commit d8fb7d0969d5c32b3d1b9e20b63ec6c0abe80be4
Author: Paolo Bonzini <pbonzini@redhat.com>
Date: Thu May 13 11:28:34 2021 -0400
vl: switch -M parsing to keyval
Switch from QemuOpts to keyval. This enables the introduction
of non-scalar machine properties, and JSON syntax in the future.
For JSON syntax to be supported right now, we would have to
consider what would happen if string-based dictionaries (produced by
-M key=val) were to be merged with strongly-typed dictionaries
(produced by -M {'key': 123}).
The simplest way out is to never enter the situation, and only allow one
-M option when JSON syntax is in use. However, we want options such as
-smp to become syntactic sugar for -M, and this is a problem; as soon
as -smp becomes a shortcut for -M, QEMU would forbid using -M '{....}'
together with -smp. Therefore, allowing JSON syntax right now for -M
would be a forward-compatibility nightmare and it would be impossible
anyway to introduce -M incrementally in tools.
Instead, support for JSON syntax is delayed until after the main
options are converted to QOM compound properties. These include -boot,
-acpitable, -smbios, -m, -semihosting-config, -rtc and -fw_cfg. Once JSON
syntax is introduced, these options will _also_ be forbidden together
with -M '{...}'.

Switch from QemuOpts to keyval. This enables the introduction
of non-scalar machine properties, and JSON syntax in the future.
For JSON syntax to be supported right now, we would have to
consider what would happen if string-based dictionaries (produced by
-M key=val) were to be merged with strongly-typed dictionaries
(produced by -M {'key': 123}).
The simplest way out is to never enter the situation, and only allow one
-M option when JSON syntax is in use. However, we want options such as
-smp to become syntactic sugar for -M, and this is a problem; as soon
as -smp becomes a shortcut for -M, QEMU would forbid using -M '{....}'
together with -smp. Therefore, allowing JSON syntax right now for -M
would be a forward-compatibility nightmare and it would be impossible
anyway to introduce -M incrementally in tools.
Instead, support for JSON syntax is delayed until after the main
options are converted to QOM compound properties. These include -boot,
-acpitable, -smbios, -m, -semihosting-config, -rtc and -fw_cfg. Once JSON
syntax is introduced, these options will _also_ be forbidden together
with -M '{...}'.

commit 8af54b9172ff3b9bbdbb3191ed84994d275a0d81
Author: Daniel P. Berrangé <berrange@redhat.com>

machine: remove 'query-cpus' QMP command
The newer 'query-cpus-fast' command avoids side effects on the guest
execution. Note that some of the field names are different in the
'query-cpus-fast' command.

machine: remove 'query-cpus' QMP command
The newer 'query-cpus-fast' command avoids side effects on the guest

target-i386: kvm: Use env->mcg_cap when setting up MCE
When setting up MCE, instead of using the MCE_*_DEF macros
directly, just filter the existing env->mcg_cap value.
As env->mcg_cap is already initialized as
MCE_CAP_DEF|MCE_BANKS_DEF at target-i386/cpu.c:mce_init(), this
doesn't change any behavior. But it will allow us to change
mce_init() in the future, to implement different defaults
depending on CPU model, machine-type or command-line parameters.

target-i386: kvm: Abort if MCE bank count is not supported by host
Instead of silently changing the number of banks in mcg_cap based
on kvm_get_mce_cap_supported(), abort initialization if the host
doesn't support MCE_BANKS_DEF banks.
Note that MCE_BANKS_DEF was always 10 since it was introduced in
QEMU, and Linux always returned 32 at KVM_CAP_MCE since
KVM_CAP_MCE was introduced, so no behavior is being changed and
the error can't be triggered by any Linux version. The point of
the new check is to ensure we won't silently change the bank
count if we change MCE_BANKS_DEF or make the bank count
configurable in the future.

target-sparc: fix 32-bit truncation in fpackfix
This is reported by Coverity. The algorithm description at
ftp://ftp.icm.edu.pl/packages/ggi/doc/hw/sparc/Sparc.pdf suggests
that the 32-bit parts of rs2, after the left shift, is treated
as a 64-bit integer. Bits 32 and above are used to do the
saturating truncation.

exec: remove warning about mempath and hugetlbfs
The gethugepagesize() method in exec.c printed a warning if
the file path for "-mem-path" or "-object memory-backend-file"
was not on a hugetlbfs filesystem. This warning is bogus, because
QEMU functions perfectly well with the path on a regular tmpfs
filesystem. Use of hugetlbfs vs tmpfs is a choice for the management
application or end user to make as best fits their needs. As such it
is inappropriate for QEMU to have an opinion on whether the user's
choice is right or wrong in this case.

Revert "exec: silence hugetlbfs warning under qtest"
This reverts commit 1c7ba94a184df1eddd589d5400d879568d3e5d08.
That commit changed QEMU initialization order from
- object-initial, chardev, qtest, object-late
to
- chardev, qtest, object-initial, object-late
This breaks chardev setups which need to rely on objects
having been created. For example, when chardevs use TLS
encryption in the future, they need to have tls credential
objects created first.
This revert, restores the ordering introduced in

In case of live migration several queues can be enabled and not only the

qjson: Limit number of tokens in addition to total size
Commit 29c75dd "json-streamer: limit the maximum recursion depth and
maximum token count" attempts to guard against excessive heap usage by
limiting total token size (it says "token count", but that's a lie).
Total token size is a rather imprecise predictor of heap usage: many
small tokens use more space than few large tokens with the same input
size, because there's a constant per-token overhead: 37 bytes on my
system.
Tighten this up: limit the token count to 2Mi. Chosen to roughly
match the 64MiB total token size limit.

qjson: surprise, allocating 6 QObjects per token is expensive
Replace the contents of the tokens GQueue with a simple struct. This cuts
the amount of memory allocated by tests/check-qjson from ~500MB to ~20MB,
and the execution time from 600ms to 80ms on my laptop. Still a lot (some
could be saved by using an intrusive list, such as QSIMPLEQ, instead of
the GQueue), but the savings are already massive and the right thing to
do would probably be to get rid of json-streamer completely.

qga: Better mapping of SEEK_* in guest-file-seek
Exposing OS-specific SEEK_ constants in our qapi was a mistake
(if the host has SEEK_CUR as 1, but the guest has it as 2, then
the semantics are unclear what should happen); if we had a time
machine, we would instead expose only a symbolic enum. It's too
late to change the fact that we have an integer in qapi, but we
can at least document what mapping we want to enforce for all
qga clients (and luckily, it happens to be the mapping that both
Linux and Windows use); then fix the code to match that mapping.
It also helps us filter out unsupported SEEK_DATA and SEEK_HOLE.
In the future, we may wish to move our QGA_SEEK_* constants into
qga/qapi-schema.json, along with updating the schema to take an
alternate type (either the integer, or the string value of the
enum name) - but that's too much risk during hard freeze.

This test exhibits a POSIX behaviour regarding switching between write

when the buffer size is relatively small). The previous commit fixes

According to the specification:
http://pubs.opengroup.org/onlinepubs/9699919799/functions/fopen.html
"the application shall ensure that output is not directly followed by
input without an intervening call to fflush() or to a file positioning
function (fseek(), fsetpos(), or rewind()), and input is not directly
followed by output without an intervening call to a file positioning
function, unless the input operation encounters end-of-file."
Without this change, an fwrite() followed by an fread() may lose the
previously written content, as shown in the following test.

Use explicit timeouts instead of trying to approximate it by counting

In practice, the timeout if inb() dwarfed the nsleep delays, and as a
result the real timeout value became a lot larger than 5 seconds.
So: change the semantics from "Not sooner than 5 seconds" to "no more

makefile: fix qemu-ga make install for --disable-tools
ab59e3e introduced a fix for `make install` on w32 that involved
filtering out qemu-ga from $TOOLS install recipe so that we could
append $(EXESUF) to it before attempting to install the binary
via install-prog function.
install-prog takes a list of binaries to install to a particular
directory. If the list is empty it breaks. We guard against this
by ensuring $TOOLS is not empty prior to calling.
However, ab59e3e introduces extra filtering after this check which
can still result on us attempting to call install-prog with an
empty list of binaries. In particular, this occurs if we
build with the --disable-tools configure option, which results
in qemu-ga being the only member of $TOOLS.
Fix this by doing a simple s/qemu-ga/qemu-ga$(EXESUF)/ pass through
$TOOLS instead of filtering out qemu-ga to handle it seperately.

will be overflow, and it will be always less than rate limit.
There is no need to read too many data into memory when the rate limit is very large.

Assume madvise for (no)hugepage works
madvise() returns EINVAL in the case of many failures, but also
returns it in cases where the host kernel doesn't have THP enabled.
Postcopy only really cares that THP is off before it detects faults,
and turns it back on afterwards; so we're going to have
to assume that if the madvise fails then the host just doesn't do
THP and we can carry on with the postcopy.

raw-posix.c: Make GetBSDPath() handle caching options
Add support for caching options that can be specified from the command
line.
The CD-ROM raw char device bypasses the host page cache and therefore
has alignment requirements. Alignment probing is necessary so only use
the raw char device if BDRV_O_NOCACHE is set.
This patch fixes -cdrom /dev/cdrom on Mac OS X hosts, where bdrv_read()
used to fail due to misaligned requests during image format probing.

It seems that we currently have some duplication between

The actual reason is that enable is not documented correctly:
what it does is connecting ring to the backend.
This is important for MQ, because a Linux guest expects TX
packets to be completed even if it disables some queues

osdep: Change default value of qemu_hw_version() to "2.5+"
There are two issues with qemu_hw_version() today:
1) If a machine has hw_version set, the value returned by it is
not very useful, because it is not the actual QEMU version.
2) If a machine does't set hw_version, the return value of
qemu_hw_version() is broken, because it will change when
upgrading QEMU.
For those reasons, using qemu_hw_version() is strongly
discouraged, and should be used only in code that used
QEMU_VERSION in the past and needs to keep compatibility.
To fix (2), instead of making every machine broken by default
unless they set hw_version, make qemu_hw_version() simply return
"2.5+" if qemu_set_hw_version() is not called.

ivshmem: Rename property memdev to x-memdev for 2.5
The device's guest interface and its QEMU user interface are
flawed^Whotly debated. We'll resolve that in the next development
cycle, probably by deprecating the device in favour of a cleaned up,
but not quite compatible revision.
To avoid adding more baggage to the soon-to-be-deprecated interface,
mark property "memdev" as experimental, by renaming it to "x-memdev".
It's the only recent user interface change.

target-mips: flush QEMU TLB when disabling 64-bit addressing
CP0.Status.KX/SX/UX bits are responsible for enabling access to 64-bit
Kernel/Supervisor/User Segments. If bit is cleared an access to
corresponding segment should generate Address Error Exception.
However, the guest may still be able to access some pages belonging to
the disabled 64-bit segment because we forget to flush QEMU TLB.
This patch fixes it.

target-mips: Fix exceptions while UX=0
Commit 01f728857941 ("target-mips: Status.UX/SX/KX enable 32-bit address
wrapping") added a new hflag MIPS_HFLAG_AWRAP, which indicates that
64-bit addressing is disallowed in the current mode, so hflag users
don't need to worry about the complexities of working that out, for
example checking both MIPS_HFLAG_KSU and MIPS_HFLAG_UX.
However when exceptions are taken outside of exception level,
mips_cpu_do_interrupt() manipulates the env->hflags directly rather than
using compute_hflags() to update them, and this code wasn't updated
accordingly. As a result, when UX is cleared, MIPS_HFLAG_AWRAP is set,
but it doesn't get cleared on entry back into kernel mode due to an
exception. Kernel mode then cannot access the 64-bit segments resulting
in a nested exception loop. The same applies to errors and debug
exceptions.
Fix by updating mips_cpu_do_interrupt() to clear the MIPS_HFLAG_WRAP
flag when necessary, according to compute_hflags().

parallels: dirty BAT properly for continuous allocations
This patch marks part of the BAT dirty properly. There is a possibility that
multy-block allocation could have one block allocated on one BAT page and
next block on the next page. The code without the patch could not save
updated position to the file.

hostmem: Ignore ENOSYS while setting MPOL_DEFAULT
Currently hostmem backend fails if CONFIG_NUMA is enabled in QEMU
(the default) but NUMA is not supported by the kernel. This makes
it impossible to use ivshmem in such configurations.
This patch fixes the problem by ignoring ENOSYS error if policy is set to
MPOL_DEFAULT. This way the code behaves in the same way as if CONFIG_NUMA
was not defined. qemu will still fail if the user specifies some other
policy, so that the user knows it.

qom: Replace object property list with GHashTable
ARM GICv3 systems with large number of CPUs create lots of IRQ pins. Since
every pin is represented as a property, number of these properties becomes
very large. Every property add first makes sure there's no duplicates.
Traversing the list becomes very slow, therefore QEMU initialization takes
significant time (several seconds for e. g. 16 CPUs).
This patch replaces list with GHashTable, making lookup very fast. The only
drawback is that object_child_foreach() and object_child_foreach_recursive()
cannot add or remove properties during traversal, since GHashTableIter does
not have modify-safe version. However, the code seems not to modify objects
via these functions.

exec: silence hugetlbfs warning under qtest
vhost-user-test prints a warning. A test should not need to run on

condition can't check on qtest_enabled() since vhost-user-test actually
doesn't use qtest accel. However, qtest_driver() can be used, if
qtest_init() is called early enough. For that reason, move chardev and

tests: re-enable vhost-user-test
Commit 7fe34ca9c2e actually disabled vhost-user-test altogether,
since CONFIG_VHOST_NET is a per-target config variable.
tests/vhost-user-test is already x86/x64 softmmu specific test, in order
to enable it correctly, kvm & vhost-net are also conditions. To check
that, set CONFIG_VHOST_NET_TEST_$target when kvm is also enabled.
Since "check-qtest-x86_64-y = $(check-qtest-i386-y)", avoid duplication
when both x86 & x64 are enabled.
Other targets than x86 aren't enabled yet, and is intentionally left as
a future improvement, since I can't easily test those.

acpi: fix buffer overrun on migration
ich calls acpi_gpe_init with length ICH9_PMIO_GPE0_LEN so
ICH9_PMIO_GPE0_LEN/2 bytes are allocated, but then the full
ICH9_PMIO_GPE0_LEN bytes are migrated.
As a quick work-around, allocate twice the memory.
We'll probably want to tweak code to avoid
migrating the extra ICH9_PMIO_GPE0_LEN/2 bytes,
but that is a bit trickier to do without breaking
migration compatibility.

qom: Add a test case for complex property finalization
Devices have some quite complex object child/link relationships
which place some requirements on the object_property_del_all()
function to consider that properties can be modified while
being iterated over.
This extends the QOM property test case to replicate the
device like structure and expose any potential bugs in the
object_property_del_all() function.

qom: Introduce ObjectPropertyIterator struct for iteration
Some users of QOM need to be able to iterate over properties
defined against an object instance. Currently they are just
directly using the QTAIL macros against the object properties
data structure.
This is bad because it exposes them to changes in the data
structure used to store properties, as well as changes in
functionality such as ability to register properties against
the class.
This provides an ObjectPropertyIterator struct which will
insulate the callers from the particular data structure
used to store properties. It can be used thus
ObjectProperty *prop;
ObjectPropertyIterator *iter;
iter = object_property_iter_init(obj);
while ((prop = object_property_iter_next(iter))) {
... do something with prop ...
}
object_property_iter_free(iter);

qdev: Change Property::offset field to ptrdiff_t type
Property::offset field is calculated as a diff between two pointers:
arrayprop->prop.offset = eltptr - (void *)dev;
If offset is declared as int, this subtraction can cause type overflow,
thus leading to failure of the subsequent assertion:
assert(qdev_get_prop_ptr(dev, &arrayprop->prop) == eltptr);
So ptrdiff_t should be used instead.

crypto: avoid passing NULL to access() syscall
The qcrypto_tls_creds_x509_sanity_check() checks whether
certs exist by calling access(). It is valid for this
method to be invoked with certfile==NULL though, since
for client credentials the cert is optional. This caused
it to call access(NULL), which happens to be harmless on
current Linux, but should none the less be avoided.

makefile: fix w32 install target for qemu-ga
fafcaf1 added a 'qemu-ga' install target on w32, which can be used
in place of the existing qemu-ga.exe target to also handle dealing
with other components such as DLLs for VSS/fsfreeze and generating
an MSI package if appropriate configure options are present.
As part of that, qemu-ga$(EXESUF) was removed from $TOOLS in favor
of this new qemu-ga target.
The install rule however relies on a direct mapping of the $TOOLS
entry to the actual resulting binary. In the case of w32, qemu-ga
is not identical to qemu-ga$(EXESUF), and the install recipe fails
to find the 'qemu-ga' binary.
Fix this by essentially remapping 'qemu-ga' back to 'qemu-ga.exe'
in the install recipe.
This raises the question of whether or not qemu-ga should continue
to live in TOOLS as opposed to its own special target, but as a
late fix for a regression in 2.5 this commit should be safer, since
we rely on qemu-ga's presence in $TOOLS in several places throughout
Makefile.

ide: orphan all buffered requests on DMA cancel
If the guests canceles a DMA request we can prematurely
invoke all callbacks of buffered requests and flag all them
as orphaned. Ideally this avoids the need for draining all
requests. For CDROM devices this works in 100% of all cases.

ide: add support for IDEBufferedRequest
this patch adds a new aio readv compatible function which copies
all data through a bounce buffer. These buffered requests can be
flagged as orphaned which means that their original callback has
already been invoked and the request has just not been completed
by the backend storage. The bounce buffer guarantees that guest
memory corruption is avoided when such a orphaned request is
completed by the backend at a later stage.
This trick only works for read requests as a write request completed
at a later stage might corrupt data as there is no way to control
if and what data has already been written to the storage.

ide/atapi: make PIO read requests async
PIO read requests on the ATAPI interface used to be sync blk requests.
This has two significant drawbacks. First the main loop hangs util an
I/O request is completed and secondly if the I/O request does not
complete (e.g. due to an unresponsive storage) Qemu hangs completely.
Note: Due to possible race conditions requests during an ongoing
elementary transfer are still sync.

KVM can't virtualize rdtscp on AMD CPUs yet, so there's no point
in enabling it by default on AMD CPU models, as all we are

Disable rdtscp on Opteron_G* models, but keep compatibility on
pc-*-2.4 and older (just in case there are people are doing funny

target-i386: Fix mulx for identical target regs
The Intel specification clearly indicates that the low part
of the result is written first and the high part of the result
is written second; thus if ModRM:reg and VEX.vvvv are identical,
the final result should be the high part of the result.
At present, TCG may either produce incorrect results or crash
with --enable-checking.

virtio-blk: Fix double completion for werror=stop
When a request R is absorbed by request M, it is appended to the
"mr_next" queue led by M, and is completed together with the completion
of M, in virtio_blk_rw_complete.
During DMA restart in virtio_blk_dma_restart_bh, requests in s->rq are
parsed and submitted again, possibly with a stale req->mr_next. It could
be a problem if the request merging in virtio_blk_handle_request hasn't
refreshed every mr_next pointer, in which case, virtio_blk_rw_complete
could walk through unexpected requests following the stale pointers.
Fix this by unsetting the pointer in virtio_blk_rw_complete. It is safe
because this req is either completed and freed right away, or it will be
restarted and parsed from scratch out of the vq later.

input: Document why x-input-send-event is still experimental
The x-input-send-event command was introduced in 2.2 with mention
that it is experimental, but now that several releases have elapsed
without any changes, it would be nice to document why that was done
and should still remain experimental in 2.5.
Meanwhile, our documentation states that we prefer 'lower-case',
rather than 'CamelCase', for qapi enum values. The InputButton and
InputAxis enums violate this convention. However, because they are
currently used primarily for generating code that is used internally;
and their only exposure through QMP is via the experimental
'x-input-send-event' command, we are free to change their spelling.
Of course, it would be nicer to delay such a change until the same
time we promote the command to non-experimental. Adding
documentation will help us remember to do that rename.
We have plans to tighten the qapi generator to flag instances of
inconsistent use of naming conventions; if that lands first, it
will just need to whitelist these exceptions until the time we
settle on the final interface.
Fix a typo in the docs for InputAxis while at it.

seccomp: loosen library version dependency
Drop the libseccomp required version back to 2.1.0, restoring the ability
to build w/ --enable-seccomp on Ubuntu 14.04.
Commit 4cc47f8b3cc4f32586ba2f7fce1dc267da774a69 tightened the dependency
on libseccomp from version 2.1.0 to 2.1.1. This broke building on Ubuntu
14.04, the current Ubuntu LTS release. The commit message didn't mention
any specific functional need for 2.1.1, just that it was the most recent
stable version at the time. I reviewed the changes between 2.1.0 and 2.1.1,
but it looks like that update just contained minor fixes and cleanups - no
obvious (to me) new interfaces or critical bug fixes.

configure: arm/aarch64: allow enable-seccomp
This is a revert of ae6e8ef11e6cb, but with a bit of refactoring,
and also specifically adding arm/aarch64, rather than all
architectures. Currently, libseccomp code appears to also support
mips, ppc, and s390. We could therefore allow qemu to enable
seccomp for those platforms as well, with additional configure
patches, given they're tested and proven to work.

xen: fix usage of xc_domain_create in domain builder
Due to the addition of HVMlite and the requirement to always provide a
valid xc_domain_configuration_t, xc_domain_create now always takes an arch
domain config, which can be NULL in order to mimic previous behaviour.
Add a small stub called xen_domain_create that encapsulates the correct
call to xc_domain_create depending on the libxc version detected.

migration_init: Fix lock initialisation/make it explicit
Peter reported a lock error on MacOS after my a82d593b
patch.
migrate_get_current does one-time initialisation of
a bunch of variables.
migrate_init does reinitialisation even on a 2nd
migrate after a cancel.
The problem here was that I'd initialised the mutex
in migrate_get_current, and the memset in migrate_init
corrupted it.
Remove the memset and replace it by explicit initialisation
of fields that need initialising; this also turns out to be simpler
than the old code that had to preserve some fields.

block: New option to define the intervals for collecting I/O statistics
The BlockAcctStats structure contains a list of BlockAcctTimedStats.
Each one of these collects statistics about the minimum, maximum and
average latencies of all I/O operations in a certain interval of time.
This patch adds a new "stats-intervals" option that allows defining
these intervals.

This module computes the average of a set of values within a time
window, keeping also track of the minimum and maximum values.
In order to produce more accurate results it works internally by
creating two time windows of the same period, offsetted by half of
that period. Values are accounted on both windows and the data is
always returned from the oldest one.

block: rename BlkTransactionState and BdrvActionOps
These structures are misnomers, somewhat.
(1) BlockTransactionState is not state for a transaction,
but is rather state for a single transaction action.
Rename it "BlkActionState" to be more accurate.
(2) The BdrvActionOps describes operations for the BlkActionState,
above. This name might imply a 'BdrvAction' or a 'BdrvActionState',
which there isn't.
Rename this to 'BlkActionOps' to match 'BlkActionState'.
Lastly, update the surrounding in-line documentation and comments
to reflect the current nature of how Transactions operate.
This patch changes only comments and names, and should not affect
behavior in any way.

compliance to the bdrv_drain semantics we should make sure it remains

We cannot reuse qed_need_check_timer_cb because here it doesn't satisfy

block: Introduce BlockDriver.bdrv_drain callback
Drivers can have internal request sources that generate IO, like the
need_check_timer in QED. Since we want quiesced periods that contain
nested event loops in block layer, we need to have a way to disable such
event sources.
Block drivers must implement the "bdrv_drain" callback if it has any
internal sources that can generate I/O activity, like a timer or a
worker thread (even in a library) that can schedule QEMUBH in an
asynchronous callback.
Update the comments of bdrv_drain and bdrv_drained_begin accordingly.
Like bdrv_requests_pending(), we should consider all the children of bs.
Before, the while loop just works, as bdrv_requests_pending() already
tracks its children; now we mustn't miss the callback, so recurse down
explicitly.

Currently all drivers that support .bdrv_aio_ioctl also implement

easier if we unify the two paths, because we'll need to run it in a
coroutine, as required by tracked_request_begin. While we're at it, use

The two fields that will be used by ioctl handling code later are added
as union, because it's used exclusively by ioctl code which dosn't need
the four fields in the other struct of the union.

virtio-9p: add savem handlers
We don't support migration of mounted 9p shares. This is handled by a
migration blocker.
One would expect, however, to be able to migrate if the share is unmounted.
Unfortunately virtio-9p-device does not register savevm handlers at all !
Migration succeeds and leaves the guest with a dangling device...
This patch simply registers migration handlers for virtio-9p-device. Whether
migration is possible or not still depends on the migration blocker.

We used to use mmio for notification. This could be slow on some arch
(e.g on x86 without EPT). So this patch introduces pio bar and a pio
notification cap for modern device. This ability is enabled through
property "modern-pio-notify" for virtio pci devices and was disabled
by default. Management can enable when it thinks it was needed.
Benchmarks shows almost no obvious difference compared to legacy
device on machines without ept. Thanks Wenli Quan <wquan@redhat.com>

virtio-pci: use zero length mmio eventfd for 1.0 notification cap when possible
We use data match eventfd for 1.0 notification currently. This could
be slow since software decoding is needed for mmio exit. To speed this
up, we can switch to use zero length mmio eventfd for 1.0 notification
since we can examine the queue index directly from the writing
address. KVM kernel module can utilize this by registering it to fast
mmio bus which could be as fast as pio on ept capable machine when
fast mmio is supported by host kernel.
Lots of improvements were seen on a ept capable machine:

virtio-pci: fix 1.0 virtqueue migration
We don't migrate the followings fields for virtio-pci:
uint32_t dfselect;
uint32_t gfselect;
uint32_t guest_features[2];
struct {
uint16_t num;
bool enabled;
uint32_t desc[2];
uint32_t avail[2];
uint32_t used[2];
} vqs[VIRTIO_QUEUE_MAX];
This will confuse driver if migrating during initialization. Solves
this issue by:
- introduce transport specific callbacks to load and store extra
virtqueue states.
- add a new subsection for virtio to migrate transport specific modern
device state.
- implement pci specific callbacks.
- add a new property for virtio-pci for whether or not to migrate
extra state.
- compat the migration for 2.4 and elder machine types

e1000: Introducing backward compatibility command line parameter
This follows the previous patches, where support for migrating the
entire MAC registers' array, and some new MAC registers were introduced.
This patch introduces the e1000-specific boolean parameter
"extra_mac_registers", which is on by default. Setting it to off will
enable migration to older versions of QEMU, but will disable the read
and write access to the new registers, that were introduced since adding
the ability to migrate the entire MAC array.
Example for usage to enable backward compatibility and to disable the
new MAC registers:
qemu-system-x86_64 -device e1000,extra_mac_registers=off,... ...
As mentioned above, the default value is "on".

e1000: Fixing the packet address filtering procedure
Previously, if promiscuous unicast was enabled, a packet was received
straight away, even if it was a multicast or a broadcast packet. This
patch fixes that behavior, while making the filtering procedure a bit
more human-readable.

e1000: Fixing the received/transmitted octets' counters
Previously, these 64-bit registers did not stick at their maximal
values when (and if) they reached them, as they should do, according to
the specs.
This patch introduces a function that takes care of such registers,
avoiding code duplication, making the relevant parts more compatible
with the QEMU coding style, while ensuring that in the unlikely case
of reaching the maximal value, the counter will stick there, as it
supposed to.

e1000: Trivial implementation of various MAC registers
These registers appear in Intel's specs, but were not implemented.
These registers are now implemented trivially, i.e. they are initiated
with zero values, and if they are RW, they can be written or read by the
driver, or read only if they are R (essentially retaining their zero
values). For these registers no other procedures are performed.
For the trivially implemented Diagnostic registers, a debug warning is
produced on read/write attempts.
PLEASE NOTE: these registers will not be active, nor will migrate, until
a compatibility flag will be set (in a later patch in this series).
The registers implemented here are:
Transmit:
RW: AIT
Management:
RW: WUC WUS IPAV IP6AT* IP4AT* FFLT* WUPM* FFMT* FFVT*
Diagnostic:
RW: RDFH RDFT RDFHS RDFTS RDFPC PBM* TDFH TDFT TDFHS

RW: FCRUC

e1000: Introduced an array to control the access to the MAC registers
The array of uint8_t's which is introduced here, contains access metadata
about the MAC registers: if a register is accessible, but partly implemented,
or if a register requires a certain compatibility flag in order to be
accessed. Currently, 6 hypothetical flags are supported (3 exist for e1000
so far) but in the future, if more than 6 flags will be needed, the datatype
of this array can simply be swapped for a larger one.
This patch is intended to solve the following current problems:
1) In a scenario of migration between different versions of QEMU, which
differ by the MAC registers implemented in them, some registers need not to
be active if a compatibility flag is set, in order to preserve the machine's
state perfectly for the older version. Checking this for each register
individually, would create a lot of clutter in the code.
2) Some registers are (or may be) only partly implemented (e.g.
placeholders that allow reading and writing, but lack other functions).
In such cases it is better to print a debug warning on read/write attempts.
As above, dealing with this functionality on a per-register level, would
require longer and more messy code.

e1000: Add support for migrating the entire MAC registers' array
This patch makes the migration of the entire array of MAC registers
possible during live migration. The entire array is just 128 KB long, so
practically no penalty should be felt when transmitting it, additionally
to the previously transmitted individual registers. The advantage here is
eliminating the need to introduce new vmstate subsections in the future,
when additional MAC registers will be implemented.
Backward compatibility is preserved by introducing a e1000-specific
boolean parameter (in a later patch), which will be on by default.
Setting it to off would enable migration to older versions of QEMU.
Additionally, this parameter will be used to control the access to the
extra MAC registers in the future.

monitor/target-ppc: Define target_get_monitor_def
At the moment get_monitor_def() returns only registers from statically
defined monitor_defs array. However there is a lot of BOOK3S SPRs
which are not in the list and cannot be printed from the monitor.
This adds a new target platform hook - target_get_monitor_def().
The hook is called if a register was not found in the static
array returned by the target_monitor_defs() hook.
The hook is only defined for POWERPC, it returns registered
SPRs and fails on unregistered ones providing the user with information
on what is actually supported on the running CPU. The register value is
saved as uint64_t as it is the biggest supported register size;
target_ulong cannot be used because of the stub - it is in a "common"
code and cannot include "cpu.h", etc; this is also why the hook prototype
is redefined in the stub instead of being included from some header.
This replaces static descriptors for GPRs, FPRs, SRs with a helper which
looks for a value in a corresponding array in the CPUPPCState.
The immediate effect is that all 32 SRs can be printed now (instead of 16);
later this can be reused for VSX or TM registers.
This replaces callbacks for MSR and XER with static descriptors in
monitor_defs as they are stored in CPUPPCState.
While we are here, this adds "cr" as a synonym of "ccr".

s390: deprecate the non-ccw machine in 2.5
The non-ccw machine for s390 (s390-virtio) is not very well maintained
and caused several issues in the past:
- aliases like virtio-blk did not work for s390
- virtio refactoring failed due to long standing bugs (e.g.see
commit cb927b8a "s390-virtio: Accommodate guests using virtqueues too early")
- some features like memory hotplug will cause trouble due to virtio storage
being above guest memory
- the boot loader bios no longer seems to work. the source code of that
loader is also no longer maintained
2.4 changed the default to the ccw machine, let's deprecate the old
machine for 2.5.

qdev: provide qdev_reset_all_fn()
For TYPE_DEVICE, the dc->reset() function is not called on system resets
yet. Until that is changed, we have to manually register a reset handler.
Let's provide qdev_reset_all_fn(), that can directly be used - just like
the reset handler that is already available for qbus.

pc-bios/s390-ccw: El Torito 16-bit boot image size field workaround
Because of El Torito spec flaw boot image size needs to be verified.
Boot catalog entry size field has 16-bit width, and specifies size
in 512-byte units.
Thus, boot image size cannot exceed 32M.
We actually search for the file to get the file size.
This is done by scanning the ISO directory tree for the ISO block number
and reading the file size from the directory entry.

s390x/pci : fix up s390 pci iommu translation function
On s390x, each pci device has its own iommu, which is only properly
setup in qemu once the mpcifc instruction used to register the
translation table has been intercepted. Therefore, for a pci device that
is not configured or has not been initialized, proper translation is
neither required nor possible. Moreover, we may not have a host bridge
device ready yet.
This was exposed by a recent vfio change that triggers iommu translation
during the initialization of the vfio pci device. Let's do an early exit
in that case.

Move the valgrind usage into the exec subshell in _qemu_io_wrapper(),
while making sure the original return value is passed back to the
caller.

qemu-iotests: fix cleanup of background processes
Commit 934659c switched the iotests to run qemu and qemu-nbd from a bash
subshell, in order to catch segfaults. Unfortunately, this means the
process PID cannot be captured via '$!'. We stopped killing qemu and
qemu-nbd processes, leaving a lot of orphaned, running qemu processes
after executing iotests.
Since the process is using exec in the subshell, the PID is the
same as the subshell PID.
Track these PIDs for cleanup using pidfiles in the $TEST_DIR. Only
track the qemu PID, however, if requested - not all usage requires
killing the process.

throttle: Use bs->throttle_state instead of bs->io_limits_enabled
There are two ways to check for I/O limits in a BlockDriverState:
- bs->throttle_state: if this pointer is not NULL, it means that this
BDS is member of a throttling group, its ThrottleTimers structure
has been initialized and its I/O limits are ready to be applied.
- bs->io_limits_enabled: if true it means that the throttle_state
pointer is valid _and_ the limits are currently enabled.
The latter is used in several places to check whether a BDS has I/O
limits configured, but what it really checks is whether requests
are being throttled or not. For example, io_limits_enabled can be
temporarily set to false in cases like bdrv_read_unthrottled() without
otherwise touching the throtting configuration of that BDS.
This patch replaces bs->io_limits_enabled with bs->throttle_state in
all cases where what we really want to check is the existence of I/O
limits, not whether they are currently enabled or not.

throttle: Check for pending requests in throttle_group_unregister_bs()
throttle_group_unregister_bs() removes a BlockDriverState from its
throttling group and destroys the timers. This means that there must
be no pending throttled requests at that point (because it would be
impossible to complete them), so the caller has to drain them first.
At the moment throttle_group_unregister_bs() is only called from
bdrv_io_limits_disable(), which already takes care of draining the
requests, so there's nothing to worry about, but this patch makes
this invariant explicit in the documentation and adds the relevant
assertions.

qcow2: avoid misaligned 64bit bswap
If we create a buffer directly on the stack by using 12 bytes, there's
no guarantee the 64bit value we want to swap will be aligned, which
could cause errors with undefined behavior.
Spotted with clang -fsanitize=undefined and observed in iotests 15, 26,
44, 115 and 121.

qemu-iotests: Test the reopening of overlay_bs in 'block-commit'
The 'block-commit' command needs the overlay image of 'top' to
be opened in read-write mode in order to update the backing file
string. If 'top' is not the active layer or its backing file then its
overlay needs to be reopened during the block job.
This is a test case for that scenario.

commit: reopen overlay_bs before base
'block-commit' needs write access to two different nodes of the chain:
- 'base', because that's where the data is written to.
- the overlay of 'top', because it needs to update the backing file
string to point to 'base' after the operation.
Both images have to be opened in read-write mode, and commit_start()
takes care of reopening them if necessary.
With the current implementation, however, when overlay_bs is reopened
in read-write mode it has the side effect of making 'base' read-only
again, eventually making 'block-commit' fail.
This needs to be fixed in bdrv_reopen(), but until we get to that it
can be worked around simply by swapping the order of base and
overlay_bs in the reopen queue.
In order to reproduce this bug, overlay_bs needs to be initially in
read-only mode. That is: the 'top' parameter of 'block-commit' cannot
be the active layer nor its immediate backing chain.

block: add a 'blockdev-snapshot' QMP command
One of the limitations of the 'blockdev-snapshot-sync' command is that
it does not allow passing BlockdevOptions to the newly created
snapshots, so they are always opened using the default values.
Extending the command to allow passing options is not a practical
solution because there is overlap between those options and some of
the existing parameters of the command.
This patch introduces a new 'blockdev-snapshot' command with a simpler
interface: it just takes two references to existing block devices that
will be used as the source and target for the snapshot.
Since the main difference between the two commands is that one of them
creates and opens the target image, while the other uses an already
opened one, the bulk of the implementation is shared.

Passing an empty string allows opening an image but not its backing
file. This was already described in the API documentation, only the
implementation was missing.
This is useful for creating snapshots using images opened with
blockdev-add, since they are not supposed to have a backing image
before the operation.

block: check for existing device IDs in external_snapshot_prepare()
The 'snapshot-node-name' parameter of blockdev-snapshot-sync allows
setting the node name of the image that is going to be created.
Before creating the image, external_snapshot_prepare() checks that the
name is not already being used. The check is however incomplete since
it only considers existing node names, but node names must not clash
with device IDs either because they share the same namespace.
If the user attempts to create a snapshot using the name of an
existing device for the 'snapshot-node-name' parameter the operation
will eventually fail, but only after the new image has been created.
This patch replaces bdrv_find_node() with bdrv_lookup_bs() to extend
the check to existing device IDs, and thus detect possible name
clashes before the new image is created.

block: Inquire tray state before tray-moved events
blk_dev_change_media_cb() is called for all potential tray movements;
however, it is possible to request closing the tray but nothing actually
happening (on a floppy disk drive without a medium).
Thus, the actual tray status should be inquired before sending a
tray-moved event (and an event should be sent whenever the status
changed).
Checking @load is now superfluous; it was necessary because it was
possible to change a medium without having explicitly opened the tray
and closed it again (or it might have been possible, at least). This is
no longer possible, though.

spapr: Handle failure of KVM_PPC_ALLOCATE_HTAB ioctl
KVM_PPC_ALLOCATE_HTAB ioctl can return -ENOMEM for KVM guests and QEMU
never handled this correctly. But this didn't cause any problems till
now as KVM_PPC_ALLOCATE_HTAB ioctl returned with smaller than requested
HTAB when enough contiguous memory wasn't available in the host.
After the proposed kernel change: https://patchwork.ozlabs.org/patch/530501/,
KVM_PPC_ALLOCATE_HTAB ioctl will not fallback to lower sized HTAB
allocation and will fail if requested HTAB size can't be met.
Check for such failures in QEMU and abort appropriately. This will
prevent guest kernel from hanging/freezing during early boot by doing
graceful exit when host is unable to allocate requested HTAB.

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

sizeof(T). Same Coccinelle semantic patch as in commit b45c03f.

vfio/pci: Hide device PCIe capability on non-express buses for PCIe VMs
When we have a PCIe VM, such as Q35, guests start to care more about
valid configurations of devices relative to the VM view of the PCI
topology. Windows will error with a Code 10 for an assigned device if
a PCIe capability is found for a device on a conventional bus. We
also have the possibility of IOMMUs, like VT-d, where the where the
guest may be acutely aware of valid express capabilities on physical
hardware.
Some devices, like tg3 are adversely affected by this due to driver
dependencies on the PCIe capability. The only solution for such
devices is to attach them to an express capable bus in the VM.

commit 371ff5a3f04cd7d05bab49ac6e80da319026d95b
Author: Dr. David Alan Gilbert <dgilbert@redhat.com>
Date: Thu Nov 5 18:11:23 2015 +0000
Inhibit ballooning during postcopy
Postcopy detects accesses to pages that haven't been transferred yet
using userfaultfd, and it causes exceptions on pages that are 'not
present'.
Ballooning also causes pages to be marked as 'not present' when the
guest inflates the balloon.
Potentially a balloon could be inflated to discard pages that are
currently inflight during postcopy and that may be arriving at about
the same time.
To avoid this confusion, disable ballooning during postcopy.
When disabled we drop balloon requests from the guest. Since ballooning
is generally initiated by the host, the management system should avoid
initiating any balloon instructions to the guest during migration,
although it's not possible to know how long it would take a guest to
process a request made prior to the start of migration.
Guest initiated ballooning will not know if it's really freed a page
of host memory or not.
Queueing the requests until after migration would be nice, but is
non-trivial, since the set of inflate/deflate requests have to
be compared with the state of the page to know what the final
outcome is allowed to be.

Disable mlock around incoming postcopy
Userfault doesn't work with mlock; mlock is designed to nail down pages

there.
munlock the pages we userfault protect before postcopy.
mlock everything again at the end if mlock is enabled.

Postcopy: Mark nohugepage before discard
Prior to servicing userfault requests we must ensure we've not got
huge pages in the area that might include non-transferred memory,
since a hugepage could incorrectly mark the whole huge page as present.
We mark the area as non-huge page (nhp) just before we perform
discards; the discard code now tells us to discard any areas
that haven't been sent (as well as any that are redirtied);
any already formed transparent-huge-pages get fragmented
by this discard process if they cotnain any discards.
Transparent huge pages that have been entirely transferred
and don't contain any discards are not broken by this mechanism;
they stay as huge pages.
By starting postcopy after a full precopy pass, many of the pages
then stay as huge pages; this is important for maintaining performance
after the end of the migration.

Postcopy; Handle userfault requests
userfaultfd is a Linux syscall that gives an fd that receives a stream
of notifications of accesses to pages registered with it and allows
the program to acknowledge those stalls and tell the accessing
thread to carry on.
We convert the requests from the kernel into messages back to the
source asking for the pages.

Round up RAMBlock sizes to host page sizes
RAMBlocks that are not a multiple of host pages in length
cause problems for postcopy (I've seen an ACPI table on aarch64
be 5k in length - i.e. 5x target-page), so round RAMBlock sizes
up to a host-page.
This potentially breaks migration compatibility due to changes
in RAMBlock sizes; however:
1) x86 and s390 I think always have host=target page size
2) When I've tried on Power the block sizes already seem aligned.
3) I don't think there's anything else that maintains per-version
machine-types for compatibility.

Don't sync dirty bitmaps in postcopy
Once we're in postcopy the source processors are stopped and memory
shouldn't change any more, so there's no need to look at the dirty
map.
There are two notes to this:
1) If we do resync and a page had changed then the page would get
sent again, which the destination wouldn't allow (since it might
have also modified the page)
2) Before disabling this I'd seen very rare cases where a page had been
marked dirtied although the memory contents are apparently identical

Page request: Consume pages off the post-copy queue
When transmitting RAM pages, consume pages that have been queued by
MIG_RPCOMM_REQPAGE commands and send them ahead of normal page scanning.
Note:
a) After a queued page the linear walk carries on from after the
unqueued page; there is a reasonable chance that the destination
was about to ask for other closeby pages anyway.
b) We have to be careful of any assumptions that the page walking
code makes, in particular it does some short cuts on its first linear
walk that break as soon as we do a queued page.
c) We have to be careful to not break up host-page size chunks, since
this makes it harder to place the pages on the destination.

MIG_CMD_PACKAGED: Send a packaged chunk of migration stream
MIG_CMD_PACKAGED is a migration command that wraps a chunk of migration
stream inside a package whose length can be determined purely by reading
its header. The destination guarantees that the whole MIG_CMD_PACKAGED
is read off the stream prior to parsing the contents.
This is used by postcopy to load device state (from the package)
while leaving the main stream free to receive memory pages.

target-arm: Clean up DISAS_UPDATE usage in AArch32 translation code
AArch32 translation code does not distinguish between DISAS_UPDATE and
DISAS_JUMP. Thus, we cannot use any of them without first updating PC in
CPU state. Furthermore, it is too complicated to update PC in CPU state
before PC gets updated in disas context. So it is hardly possible to
correctly end TB early if is is not likely to be executed before calling
disas_*_insn(), e.g. just after calling breakpoint check helper.
Modify DISAS_UPDATE and DISAS_JUMP usage in AArch32 translation and
apply to them the same semantic as AArch64 translation does:
- DISAS_UPDATE: update PC in CPU state when finishing translation
- DISAS_JUMP: preserve current PC value in CPU state when finishing
translation
This patch fixes a bug in AArch32 breakpoint handling: when
check_breakpoints helper does not generate an exception, ending the TB
early with DISAS_UPDATE couldn't update PC in CPU state and execution
hangs.

Use the ARM boot board-setup feature to implement this. The SMC trap
implements the needed nop while all other traps will pen the CPU.
As a KVM CPU cannot run in secure mode, do not do the board-setup if

arm: boot: Add secure_board_setup flag
Add a flag that when set, will cause the primary CPU to start in secure
mode, even if the overall boot is non-secure. This is useful for when
there is a board-setup blob that needs to run from secure mode, but
device and secondary CPU init should still be done as-normal for a non-
secure boot.

hw/intc/arm_gic: Remove the definition of NUM_CPU
arm_gic.c retrieves CPU number using either NUM_CPU(s) or s->num_cpu.
Such mixed-uses make source code inconsistent. This patch removes
NUM_CPU(s), which was defined for MPCore tweak long ago, and instead
favors s->num_cpu. The source is more consistent after this small tweak.

qapi-introspect: Document lack of sorting
qapi-code-gen.txt already claims that types, commands, and
events share a common namespace; set this in stone by further
documenting that our introspection output will never have
collisions with the same name tied to more than one meta-type.
Our largest QMP enum currently has 125 values, our largest
object type has 27 members, and the mean for each is less than
10. These sizes are small enough that the per-element overhead
of O(log n) binary searching probably outweighs the speed
possible with direct O(n) linear searching (a better algorithm
with more overhead will only beat a leaner naive algorithm only
as you scale to larger input sizes).
Arguably, the overall SchemaInfo array could be sorted by name;
there, we currently have 531 entities, large enough for a binary
search to be faster than linear. However, remember that we have
mutually-recursive types, which means there is no topological
ordering that will allow clients to learn all information about
that type in a single linear pass; thus clients will want to do
random access over the data, and they will probably read the
introspection output into a hashtable for O(1) lookup rather
than O(log n) binary searching, at which point, pre-sorting our
introspection output doesn't help the client.
It doesn't help that sorting can be subjective if you introduce
locales into the mix (I'm not experienced enough with Python
to know for sure, but at least it looks like it defaults to
sorting in the C locale even when run under a different locale).
And while our current introspection output is deterministic
(because we visit entities in a sorted order), we may want
to change that order in the future (such as using OrderedDict
to stick to .json declaration order).
For these reasons, we simply document that clients should not
rely on any particular order of items in introspection output.
And since it is now a documented part of the contract, we have
the freedom to later rearrange output if needed, without
worrying about breaking well-written clients.

qapi: Provide nicer array names in introspection
For the sake of humans reading introspection output, it is nice
to have the name of implicit array types be recognizable as
arrays of the underlying type. However, while this patch allows
humans to skip from a command with return type "[123]" straight
to the definition of type "123" without having to first inspect
type "[123]", document that this shortcut should not be taken by
client apps.
This makes the resulting introspection string slightly larger by
default (just over 200 bytes), but it's in the noise (less than
0.3% of the overall 70k size of 'query-qmp-capabilities').

qapi: More tests of input arrays
Our testsuite had no coverage of empty arrays, nor of what
happens when the input does not match the expected type.
Useful to have, especially if we start changing the visitor
contracts.
I did not think it worth duplicating these additions to
test-qmp-input-strict; since all strict mode does is add
the ability to reject JSON input that has more keys than
what the visitor expects, yet the additions in this patch
error out earlier than that point regardless of whether
strict mode was requested.

qapi: Test failure in middle of array parse
Our generated list visitors have the same problem as has been
mentioned elsewhere (see commit 2f52e20): they allocate data
even on failure. An upcoming patch will correct things to
provide saner guarantees, but first we need to expose the
behavior in the testsuite to ensure we aren't introducing any
memory usage bugs.
There are more test cases throughout the test-qmp-input-* tests
that already deal with partial allocation; a later commit will
clean up all visit_type_FOO(), without marking all of the tests
with FIXME at this time.

qapi: Simplify error cleanup in test-qmp-*
We have several tests that perform multiple sub-actions that are
expected to fail. Asserting that an error occurred, then clearing
it up to prepare for the next action, turned into enough
boilerplate that it was sometimes forgotten (for example, a number
of tests added to test-qmp-input-visitor.c in d88f5fd leaked err).
Worse, if an error is not reset to NULL, we risk invalidating
later use of that error (passing a non-NULL err into a function
is generally a bad idea). Encapsulate the boilerplate into a
single helper function error_free_or_abort(), and consistently
use it.
The new function is added into error.c for use everywhere,
although it is anticipated that testsuites will be the main
client.

hw/timer/hpet.c: Avoid signed integer overflow which results in bugs on OSX
Signed integer overflow in C is undefined behaviour, and the compiler
is at liberty to assume it can never happen and optimize accordingly.
In particular, the subtractions in hpet_time_after() and hpet_time_after64()
were causing OSX clang to optimize the code such that it was prone to
hangs and complaints about the main loop stalling (presumably because
we were spending all our time trying to service very high frequency
HPET timer callbacks). The clang sanitizer confirms the UB:
hw/timer/hpet.c:119:26: runtime error: signed integer overflow: -2146967296 - 2147003978 cannot be represented in type 'int'
Fix this by doing the subtraction as an unsigned operation and then
converting to signed for the comparison.

qapi: Simplify non-error testing in test-qmp-*
By using &error_abort, we can avoid a local err variable in
situations where we expect success. It also has the nice
effect that if the test breaks, the error message from
error_abort tends to be nicer than that of g_assert().
This patch has an additional bonus of fixing several call sites that
were passing &err to two different functions without checking it in
between. In general that is unsafe practice; because if the first
function sets an error, the second function could abort() if it tries to
set a different error. We got away with it because we were asserting
that err was NULL through the entire chain, but switching to
&error_abort avoids the questionable practice up front.

qapi: Plug leaks in test-qmp-*
Make valgrind happy with the current state of the tests, so that
it is easier to see if future patches introduce new memory problems
without being drowned in noise. Many of the leaks were due to
calling a second init without tearing down the data from an earlier
visit. But since teardown is already idempotent, and we already
register teardown as part of input_visitor_test_add(), it is nicer
to just make init() safe to call multiple times than it is to have
to make all tests call teardown.
Another common leak was forgetting to clean up an error object,
after testing that an error was raised.
Another leak was in test_visitor_in_struct_nested(), failing to
clean the base member of UserDefTwo. Cleaning that up left
check_and_free_str() as dead code (since using the qapi_free_*
takes care of recursion, and we don't want double frees).
A final leak was in test_visitor_out_any(), which was reassigning
the qobj local variable to a subset of the overall structure
needing freeing; it did not result in a use-after-free, but
was not cleaning up all the qdict.
test-qmp-event and test-qmp-commands were already clean.

qapi: Share test_init code in test-qmp-input*
Rather than duplicate the body of two functions just to
decide between qobject_from_jsonv() and qobject_from_json(),
exploit the fact that qobject_from_jsonv() intentionally
takes 'va_list *' instead of the more common 'va_list', and
that qobject_from_json() just calls qobject_from_jsonv(,NULL).
For each file, our two existing init functions then become
thin wrappers around a new internal function, and future
updates to initialization don't have to be duplicated.

qapi: Use generated TestStruct machinery in tests
Commit d88f5fd and friends first introduced the various test-qmp-*
tests in 2011, with duplicated hand-rolled TestStruct machinery,
to make sure the qapi visitor interface was tested. Later, commit
4f193e3 in 2013 added a .json file for further testing use by the
files, but without consolidating any of the existing hand-rolled
visitors. And with four copies, subtle differences have crept in,
between the tests themselves (mainly whitespace differences, but
also a question of whether to use NULL or "TestStruct" when
calling visit_start_struct()) and from what the generator produces
(the hand-rolled versions did not cater to partially-allocated
objects, because they did not have a deallocation usage).
Of course, just because the visitor interface is tested does not
mean it is a sane interface; and future patches will be changing
some of the visitor contracts. Rather than having to duplicate
the cleanup work in each copy of the TestStruct visitor, and keep
each hand-rolled copy in sync with what the generator supplies, we
might as well just test what the generator should give us in the
first place.

aio: Introduce aio-epoll.c
To minimize code duplication, epoll is hooked into aio-posix's
aio_poll() instead of rolling its own. This approach also has both
compile-time and run-time switchability.
1) When QEMU starts with a small number of fds in the event loop, ppoll
is used.
2) When QEMU starts with a big number of fds, or when more devices are
hot plugged, epoll kicks in when the number of fds hits the threshold.
3) Some fds may not support epoll, such as tty based stdio. In this
case, it falls back to ppoll.
A rough benchmark with scsi-disk on virtio-scsi dataplane (epoll gets
enabled from 64 onward). Numbers are in MB/s.
===============================================
| master | epoll
| |
scsi disks # | read randrw | read randrw
-------------|----------------|----------------
1 | 86 36 | 92 45
8 | 87 43 | 86 41
64 | 71 32 | 70 38
128 | 48 24 | 58 31
256 | 37 19 | 57 28
===============================================
To comply with aio_{disable,enable}_external, we always use ppoll when
aio_external_disabled() is true.

since the field is also referenced outside CONFIG_EPOLL code.

dataplane: support non-contigious s/g
bring_map currently fails if one of the entries it's mapping is
contigious in GPA but not HVA address space. Introduce a mapped_len
parameter so it can handle this, returning the actual mapped length.
This will still fail if there's no space left in the sg, but luckily max
queue size in use is currently 256, while max sg size is 1024, so we
should be OK even is all entries happen to cross a single DIMM boundary.
Won't work well with very small DIMM sizes, unfortunately:
e.g. this will fail with 4K DIMMs where a single
request might span a large number of DIMMs.
Let's hope these are uncommon - at least we are not breaking things.

ide: remove hardcoded 2GiB transactional limit
Not that you can request a >2GiB transaction, but that's why checking
for it makes no sense anymore.
With the newer 'limit' parameter to prepare_buf, we no longer need a
static limit. The maximum limit is still 2GiB, but the limit parameter
is set to the current transaction size, which cannot surpass 32MiB
(512 * 65536). If the PRDT surpasses the transactional size, then,
we'll just carry out the normative underflow handling pathways instead
of needing an extra, strange pathway that worries about hitting some
logistical cap for the largest sglist we can support -- we'll never
even attempt to build one that big anymore.

qemu-sockets: do not test path with access() before unlinking
Using access() is a time-of-check/time-of-use race condition. It is
okay to use them to provide better error messages, but that is pretty
much it.
This is not one such case; on the other hand, access() *will* skip
unlink() for a non-existent path, so ignore ENOENT return values from
the unlink() system call.

gdbstub: Fix buffer overflows in gdb_handle_packet()
Some places in gdb_handle_packet() can get an arbitrary length (most

replay: ptimer
This patch adds deterministic replay for hardware periodic countdown timers.
ptimer uses bottom halves layer to execute such an asynchronous callback.
We put this callback into the replay queue instead of bottom halves one.
When checkpoint is met by main loop thread, the replay queue is processed
and callback is executed. Binding callback moment to one of the checkpoints
makes it deterministic.

replay: recording and replaying clock ticks
Clock ticks are considered as the sources of non-deterministic data for
virtual machine. This patch implements saving the clock values when they
are acquired (virtual, host clock).
When replaying the execution corresponding values are read from log and
transfered to the module, which wants to read the values.
Such a design required the clock polling to be synchronized. Sometimes
it is not true - e.g. when timeouts for timer lists are checked. In this case
we use a cached value of the clock, passing it to the client code.

target-i386: Set "check=off" by default on pc-*-2.4 and older
The default CPU model (qemu64) have some issues today: it enables some
features (ABM and SSE4a) that are not present in many host CPUs. That
means many hosts (but not all of them) had those features silently
disabled in the default configuration in QEMU 2.4 and older.
With the new "check=on" default, this causes warnings to be printed in
the default configuration, because of the lack of SSE4A on all Intel
hosts, and the lack of ABM on Sandy Bridge and older hosts:
$ qemu-system-x86_64 -machine pc,accel=kvm
warning: host doesn't support requested feature: CPUID.80000001H:ECX.abm [bit 5]
warning: host doesn't support requested feature: CPUID.80000001H:ECX.sse4a [bit 6]
Those issues will be fixed in pc-*-2.5 and newer. But as we can't change
the guest ABI in pc-*-2.4, disable "check" mode by default in pc-*-2.4
and older so we don't print spurious warnings.

kvmclock: add a new function to update env->tsc.
The commit 317b0a6d8 fixed an issue which caused by the outdated
env->tsc value, but the fix lead to 'cpu_synchronize_all_states()'
called twice during live migration. The 'cpu_synchronize_all_states()'
takes about 130us for a VM which has 4 vcpus, it's a bit expensive.
Synchronize the whole CPU context just for updating env->tsc is too
wasting, this patch use a new function to update the env->tsc.
Comparing to 'cpu_synchronize_all_states()', it only takes about 20us.

configure: disable FORTIFY_SOURCE under clang
Some versions of clang may have difficulty compiling glibc headers when
-D_FORTIFY_SOURCE is used. For example, Clang++ 3.5.0-9.fc22 cannot
compile glibc's stdio headers when -D_FORTIFY_SOURCE=2 is used. This
manifests currently as build failures with clang and any arm target.
According to LLVM dev Richard Smith, clang does not target or support
FORTIFY_SOURCE + glibc, and it should not be relied on.
"It's still an unsupported combination, and while it might compile, some
of the checks are unlikely to work because they require a frontend
inliner to be useful"
See: http://lists.llvm.org/pipermail/cfe-dev/2015-November/045846.html
Conclusion: disable fortify-source if we appear to be using clang instead
of testing for compile success or failure, which may be incidental or not
indicative of proper support of the feature.

backends/hostmem-file: Allow to specify full pathname for backing file
This allows to explicitly specify file name to use with the backend. This
is important when using it together with ivshmem in order to make it backed
by hugetlbfs. By default filename is autogenerated using mkstemp(), and the
file is unlink()ed after creation, effectively making it anonymous. This is
not very useful with ivshmem because it ends up in a memory which cannot be
accessed by something else.
Distinction between directory and file name is done by stat() check. If an
existing directory is given, the code keeps old behavior. Otherwise it
creates or opens a file with the given pathname.

configure: disallow ccache during compile tests
If the user is using ccache during the configuration step,
it may interfere with some of the configuration tests,
particularly the "Is ccache interfering with macro analysis" step,
which is a bit of a poetic problem.
1) Disallow ccache from reading from the cache during configure,
but don't disable it entirely to allow us to see if it causes other
problems.
2) Force off CCACHE_CPP2 during the ccache test to get a deterministic
answer over whether or not we need to enable that feature later.

cpu-exec: Fix compiler warning (-Werror=clobbered)
Reloading of local variables after sigsetjmp is only needed for some
buggy compilers.
The code which should reload these variables causes compiler warnings
with gcc 4.7 when compiler optimizations are enabled:
cpu-exec.c:204:15: error:
variable ‘cpu’ might be clobbered by ‘longjmp’ or ‘vfork’ [-Werror=clobbered]
cpu-exec.c:207:15: error:
variable ‘cc’ might be clobbered by ‘longjmp’ or ‘vfork’ [-Werror=clobbered]
cpu-exec.c:202:28: error:
argument ‘env’ might be clobbered by ‘longjmp’ or ‘vfork’ [-Werror=clobbered]
Now this code is only used for compilers which need it
(and gcc 4.5.x, x > 0 which does not need it but won't give warnings).
There were bug reports for clang and gcc 4.5.0, while gcc 4.5.1
was reported to work fine without the reload code. For clang it
is not clear which versions are affected, so simply keep the status quo
for all clang compilations. This can be improved later.

memory: call begin, log_start and commit when registering a new listener
This ensures that cpu_reload_memory_map() is called as soon as
tcg_cpu_address_space_init() is called, and before cpu->memory_dispatch
is used. qemu-system-s390x never changes the address spaces after
tcg_cpu_address_space_init() is called, and thus tcg_commit() is never
called. This causes a SIGSEGV.
Because memory_map_init() will now call mem_commit(), we have to
initialize io_mem_* before address_space_memory and friends.

osdep: Rename qemu_{get, set}_version() to qemu_{, set_}hw_version()
This makes the purpose of the function clearer: it is not about the
version of QEMU that's running, but the version string exposed in the
emulated hardware.

pc: Set hw_version on all machine classes
In 2012, QEMU had a bug where it exposed QEMU version information to the
guest, meaning a QEMU upgrade would expose different hardware to the
guest OS even if the same machine-type is being used.
The bug was fixed by commit 93bfef4c6e4b23caea9d51e1099d06433d8835a4, on
all machines up to pc-1.0. But we kept introducing the same bug on all
newer machines since then. That means we are breaking guest ABI every
time QEMU was upgraded.
Fix this by setting the hw_version on all PC machines, making sure the
hardware won't change when upgrading QEMU.
Note that QEMU_VERSION was "1.0" in QEMU 1.0, but starting on QEMU
1.1.0, it started following the "x.y.0" pattern. We have to follow it,
to make sure we use the right QEMU_VERSION string from each QEMU
release.
The 2.5 machine classes could have hw_version unset, because the default
value for qemu_get_version() is QEMU_VERSION. But I decided to set it
explicitly to QEMU_VERSION so we don't forget to update it to "2.5.0"
after we release 2.5.0 and create a 2.6 machine class.

target-i386: fix pcmpxstrx equal-ordered (strstr) mode
In this mode, referring an invalid element of the source forces the
result to false (table 4-7, last column) but referring an invalid
element of the destination forces the result to true, so the outer
loop should still be run even if some elements of the destination
will be invalid. They will be avoided in the inner loop, which
correctly bounds "i" to validd, but they will still contribute to a
positive outcome of the search.
This fixes tst_strstr in glibc 2.17.

qga: set file descriptor in qmp_guest_file_open non-blocking on Win32
Set fd non-blocking to avoid common use cases (like reading from a
named pipe) from hanging the agent. This was missed in the original
code.
The patch introduces qemu_set_handle_nonoblocking, the local analog
of qemu_set_nonblock for HANDLES.
The usage of handles in qemu_set_non/block is impossible, because for
win32 there is a difference between file discriptors and file handles,
and all file ops are made via Win32 api.

migration: defer migration_end & blk_mig_cleanup
Because of the patch 3ea3b7fa9af067982f34b of kvm, which introduces a
lazy collapsing of small sptes into large sptes mechanism, now
migration_end() is a time consuming operation because it calls
memroy_global_dirty_log_stop(), which will trigger the dropping of small
sptes operation and takes about dozens of milliseconds, so call
migration_end() before all the vmsate data has already been transferred
to the destination will prolong VM downtime. This operation should be
deferred after all the data has been transferred to the destination.
blk_mig_cleanup() can be deferred too.
For a VM with 8G RAM, this patch can reduce the VM downtime about 30 ms.

is cleared, and the specs mention setting suspend with enable being
unset is undefined behavior. So clearing them both looks reasonable,
and it actually fixes the reported bug.

vnc: fix bug: vnc server can't start when 'to' is specified
commit e0d03b8ceb52 converted VNC startup to use SocketAddress,
the interface socket_listen don't have a port_offset param, so
we need to add the port offset (5900) to both 'port' and 'to' opts.
currently only 'port' is added by offset.
This patch add the port offset to 'to' opts.

vnc: allow fall back to RAW encoding
I have observed that depending on the contents and the encoding it happens
that sending data as RAW sometimes would take less space than the encoded data.
This is especially the case for small updates or areas with high color images.
If sending RAW encoded data is beneficial allow a fall back to RAW encoding
for the framebuffer update.

ui/opengl: Reduce build required libraries for opengl
We now use epoxy to load opengl libraries. This means we don't need to
link opengl libraries directly if interfaces handled by epoxy. With
this, we just need epoxy headers and epoxy's *.so to build.
Tested with epoxy-1.3.1.
- sdl2/gtk/console egl stuff doesn't require other than epoxy
- milkymist-tmu2 glx stuff doesn't require other than epoxy
(lm32 test is limited, because can't find mmone-bios.bin, so just test
to load libGL with "./lm32-softmmu/qemu-system-lm32 -M milkymist,accel=qtest")

ui/curses: Fix pageup/pagedown on -curses
Current KEY_NPAGE/KEY_PPAGE handling is broken on -curses. Those uses
"GREY", but "KEY_MASK" masked out "GREY".
To fix, we have to use correct mask value - SCANCODE_KEYMASK.
Then, this adds support of "shift + pageup/pagedown". With this,
-curses mode can use scroll-up/down as usual like other display modes.

ui/curses: Fix monitor color with -curses when 256 colors
If TERM=xterm-256color, COLOR_PAIRS==256 and monitor passes chtype
like 0x74xx. Then, the code uses uninitialized color pair. As result,
monitor uses black for both of fg and bg color, i.e. terminal is
filled by black.

file_ram_alloc: propagate error to caller instead of terminating QEMU
QEMU shouldn't exits from file_ram_alloc() if -mem-prealloc option is specified

Propagate error to a caller and let it decide what to do with allocation failure.

kills QEMU at startup time if backends or initial memory were misconfigured/

qapi: Reserve 'u' member name
Now that we have separated union tag values from colliding with
non-variant C names, by naming the union 'u', we should reserve
this name for our use. Note that we want to forbid 'u' even in
a struct with no variants, because it is possible for a future
qemu release to extend QMP in a backwards-compatible manner while
converting from a struct to a flat union. Fortunately, no
existing clients were using this member name. If we ever find
the need for QMP to have a member 'u', we could at that time
relax things, perhaps by having c_name() munge the QMP member to
'q_u'.
Note that we cannot forbid 'u' everywhere (by adding the
rejection code to check_name()), because the existing QKeyCode
enum already uses it; therefore we only reserve it as a struct
type member name.

qapi: Finish converting to new qapi union layout
We have two issues with our qapi union layout:
1) Even though the QMP wire format spells the tag 'type', the
C code spells it 'kind', requiring some hacks in the generator.
2) The C struct uses an anonymous union, which places all tag
values in the same namespace as all non-variant members. This
leads to spurious collisions if a tag value matches a non-variant
member's name.
This patch is the back end for a series that converts to a
saner qapi union layout. Now that all clients have been
converted to use 'type' and 'obj->u.value', we can drop the
temporary parallel support for 'kind' and 'obj->value'.
Given a simple union qapi type:
{ 'union':'Foo', 'data': { 'a':'int', 'b':'bool' } }
this is the overall effect, when compared to the state before
this series of patches:
| struct Foo {
|- FooKind kind;
|- union { /* union tag is @kind */
|+ FooKind type;
|+ union { /* union tag is @type */
| void *data;
| int64_t a;
| bool b;
|- };
|+ } u;
| };
The testsuite still contains some examples of artificial restrictions
(see flat-union-clash-type.json, for example) that are no longer
technically necessary, now that there is no longer a collision between
enum tag values and non-variant member names; but fixing this will be
done in later patches, in part because some further changes are required
to keep QAPISchema*.check() from asserting. Also, a later patch will
add a reservation for the member name 'u' to avoid a collision between a
user's non-variant names and our internal choice of C union name.
Note, however, that we do not rename the generated enum, which
is still 'FooKind'. A further patch could generate implicit
enums as 'FooType', but while the generator already reserved
the '*Kind' namespace (commit 4dc2e69), there are already QMP
constructs with '*Type' naming, which means changing our
reservation namespace would have lots of churn to C code to
deal with a forced name change.

1) Even though the QMP wire format spells the tag 'type', the
C code spells it 'kind', requiring some hacks in the generator.
2) The C struct uses an anonymous union, which places all tag
values in the same namespace as all non-variant members. This
leads to spurious collisions if a tag value matches a non-variant
member's name.
Make the conversion to the new layout for block-related code.

qapi: Start converting to new qapi union layout
We have two issues with our qapi union layout:
1) Even though the QMP wire format spells the tag 'type', the
C code spells it 'kind', requiring some hacks in the generator.
2) The C struct uses an anonymous union, which places all tag
values in the same namespace as all non-variant members. This
leads to spurious collisions if a tag value matches a non-variant
member's name.
This patch is the front end for a series that converts to a
saner qapi union layout. By the end of the series, we will no
longer have the type/kind mismatch, and all tag values will be
under a named union, which requires clients to access
'obj->u.value' instead of 'obj->value'. But since the
conversion touches a number of files, it is easiest if we
temporarily support BOTH layouts simultaneously.
Given a simple union qapi type:
{ 'union':'Foo', 'data': { 'a':'int', 'b':'bool' } }
make the following changes in generated qapi-types.h:
| struct Foo {
|- FooKind kind;
|- union { /* union tag is @kind */
|+ union {
|+ FooKind kind;
|+ FooKind type;
|+ };
|+ union { /* union tag is @type */
| void *data;
| int64_t a;
| bool b;
|+ union { /* union tag is @type */
|+ void *data;
|+ int64_t a;
|+ bool b;
|+ } u;
| };
| };
Flat unions do not need the anonymous union for the tag member,
as we already fixed that to use the member name instead of 'kind'
back in commit 0f61af3e.
One additional change is needed in qapi.py: check_union() now
needs to check for collisions with 'type' in addition to those
with 'kind'.
Later, when the conversions are complete, we will remove the
duplication hacks, and also drop the check_union() restrictions.
Note, however, that we do not rename the generated enum, which
is still 'FooKind'. A further patch could generate implicit
enums as 'FooType', but while the generator already reserved
the '*Kind' namespace (commit 4dc2e69), there are already QMP
constructs with '*Type' naming, which means changing our
reservation namespace would have lots of churn to C code to
deal with a forced name change.

qapi-visit: Remove redundant functions for flat union base
The code for visiting the base class of a child struct created
visit_type_Base_fields() which covers all fields of Base; while
the code for visiting the base class of a flat union created
visit_type_Union_fields() covering all fields of the base
except the discriminator. But since the base class includes
the discriminator of a flat union, we can just visit the entire
base, without needing a separate visit of the discriminator.
Not only is consistently visiting all fields easier to
understand, it lets us share code.
The generated code in qapi-visit.c loses several now-unused
visit_type_UNION_fields(), along with changes like:
|@@ -1654,11 +1557,7 @@ void visit_type_BlockdevOptions(Visitor
| if (!*obj) {
| goto out_obj;
| }
|- visit_type_BlockdevOptions_fields(v, obj, &err);

|+ visit_type_BlockdevOptionsBase_fields(v, (BlockdevOptionsBase **)obj, &err);
| if (err) {
| goto out_obj;
| }
and forward declarations where needed. Note that the cast of obj
to BASE ** is necessary to call visit_type_BASE_fields() (and we
can't use our upcast wrappers, because those work on pointers while
we have a pointer-to-pointer).

qapi: Unbox base members
Rather than storing a base class as a pointer to a box, just
store the fields of that base class in the same order, so that
a child struct can be directly cast to its parent. This gives
less malloc overhead, less pointer dereferencing, and even less
generated code. Compare to the earlier commit 1e6c1616a "qapi:
Generate a nicer struct for flat unions" (although that patch
had fewer places to change, as less of qemu was directly using
qapi structs for flat unions). It also allows us to turn on
automatic type-safe wrappers for upcasting to the base class
of a struct.
Changes to the generated code look like this in qapi-types.h:
| struct SpiceChannel {
|- SpiceBasicInfo *base;
|+ /* Members inherited from SpiceBasicInfo: */
|+ char *host;
|+ char *port;
|+ NetworkAddressFamily family;
|+ /* Own members: */
| int64_t connection_id;
as well as additional upcast functions like qapi_SpiceChannel_base().
Meanwhile, changes to qapi-visit.c look like:
| static void visit_type_SpiceChannel_fields(Visitor *v, SpiceChannel **obj, Error **errp)
| {
| Error *err = NULL;
|
|- visit_type_implicit_SpiceBasicInfo(v, &(*obj)->base, &err);
|+ visit_type_SpiceBasicInfo_fields(v, (SpiceBasicInfo **)obj, &err);
| if (err) {
(the cast is necessary, since our upcast wrappers only deal with a
single pointer, not pointer-to-pointer); plus the wholesale
elimination of some now-unused visit_type_implicit_FOO() functions.
Without boxing, the corner case of one empty struct having
another empty struct as its base type now requires inserting a
dummy member (previously, the 'Base *base' member sufficed).
And now that we no longer consume a 'base' member in the generated
C struct, we can delete the former negative struct-base-clash-base
test.

qapi: Prefer typesafe upcasts to qapi base classes
A previous patch (commit 1e6c1616) made it possible to
directly cast from a qapi flat union type to its base type.
However, it requires the use of a C cast, which turns off
compiler type-safety checks. Fortunately, no such casts
exist, just yet.
Regardless, add inline type-safe wrappers named
qapi_FOO_base() for any union type FOO that has a base,
which can be used for a safer upcast, and enhance the
testsuite to cover the new functionality.
A future patch will extend the upcast support to structs,
where such conversions do exist already.
Note that C makes const-correct upcasts annoying because
it lacks overloads; these functions cast away const so that
they can accept user pointers whether const or not, and the
result in turn can be assigned to normal or const pointers.
Alternatively, this could have been done with macros, but
type-safe macros are hairy, and not worthwhile here.
This patch just adds upcasts. None of our code needed to
downcast from a base qapi class to a child. Also, in the
case of grandchildren (such as BlockdevOptionsQcow2), the
caller will need to call two functions to get to the inner
base (although it wouldn't be too hard to generate a
qapi_FOO_base_base() if desired). If a user changes qapi
to alter the base class hierarchy, such as going from
'A -> C' to 'A -> B -> C', it will change the type of
'qapi_C_base()', and the compiler will point out the places
that are affected by the new base.
One alternative was proposed, but was deemed too ugly to use
in practice: the generators could output redundant
information using anonymous types:
| struct Child {
| union {
| struct {
| Type1 parent_member1;
| Type2 parent_member2;
| };
| Parent base;
| };
| };
With that ugly proposal, for a given qapi type, obj->member
and obj->base.member would refer to the same storage; allowing
convenience in working with members without needing 'base.'
allowing typesafe upcast without needing a C cast by accessing
'&obj->base', and allowing downcasts from the parent back to
the child possible through container_of(obj, Child, base).

A future qapi patch will rework generated structs with a base
class to be unboxed. In preparation for that, change the code
that allocates then populates an info struct to instead merely
populate the fields of an info field passed in as a parameter
(renaming vnc_basic_info_get* to vnc_init_basic_info*). Add
rudimentary Error handling at the lowest levels for cases
where the old code returned NULL; but rather than plumb Error
all the way through the stack, the callers drop the error and
return NULL as before.

qapi: Reserve 'q_*' and 'has_*' member names
c_name() produces names starting with 'q_' when protecting a
dictionary member name that would fail to directly compile, but
in doing so can cause clashes with any member name already
beginning with 'q-' or 'q_'. Likewise, we create a C name 'has_'
for any optional member that can clash with any member name
beginning with 'has-' or 'has_'.
Technically, rather than blindly reserving the namespace,
we could try to complain about user names only when an actual
collision occurs, or even teach c_name() how to munge names
to avoid collisions. But it is not trivial, especially when
collisions can occur across multiple types (such as via
inheritance or flat unions). Besides, no existing .json
files are trying to use these names. So it's easier to just
outright forbid the potential for collision. We can always
relax things in the future if a real need arises for QMP to
express member names that have been forbidden here.
'has_' only has to be reserved for struct/union member names,
while 'q_' is reserved everywhere (matching the fact that
only members can be optional, while we use c_name() for munging
both members and entities). Note that we could relax 'q_'
restrictions on entities independently from member names; for
example, c_name('qmp_' + 'unix') would result in a different
function name than our current 'qmp_' + c_name('unix').
Update and add tests to cover the new error messages.

qapi: More robust conditions for when labels are needed
We were using regular expressions to see if ret included
any earlier text that emitted a 'goto out;' line, to decide
whether we needed to output an 'out:' label. But this is
fragile, if the ret text can possibly combine more than one
generated function body, where the first function used a
goto but the second does not. Change the code to just check
for the known conditions which cause an error check to be
needed. Besides, it's slightly more efficient to use plain
checks than regular expression searching.

tests/qapi-schema: Test for reserved names, empty struct
Add some testsuite coverage to ensure future patches are on
the right track:
Our current C representation of qapi arrays is done by appending
'List' to the element name; but we are not preventing the
creation of an object type with the same name. Add
reserved-type-list.json to test this. Then rename
enum-union-clash.json to reserved-type-kind.json to cover the
reservation that we DO detect, and shorten it to match the fact
that the name is reserved even if there is no clash.
We are failing to detect a collision between a dictionary member
and the implicit 'has_*' flag for another optional member. The
easiest fix would be for a future patch to reserve the entire
"has[-_]" namespace for member names (the collision is also
possible for branch names within flat unions, but only as long as
branch names can collide with (non-variant) members; however,
since future patches are about to remove that, it is not worth
testing here). Add reserved-member-has.json to test this.
A similar collision exists between a dictionary member where
c_name() munges what might otherwise be a reserved name to start
with 'q_', and another member explicitly starts with "q[-_]".
Again, the easiest solution for a future patch will be reserving
the entire namespace, but here for commands as well as members.
Add reserved-member-q.json and reserved-command-q.json to test
this; separate tests since arguably our munging of command 'unix'
to 'qmp_q_unix()' could be done without a q_, which is different
than the munging of a member 'unix' to 'foo.q_unix'.
Finally, our testsuite does not have any compilation coverage
of struct inheritance with empty qapi structs. Update
qapi-schema-test.json to test this.
Note that there is currently no technical reason to forbid type
name patterns from member names, or member name patterns from
types, since the two are not in the same namespace in C and
won't collide; but it's not worth adding positive tests of these
corner cases at this time, especially while there is other churn
pending in patches that rearrange which collisions actually
happen.

hw/mips_malta: Fix KVM PC initialisation
Commit 71c199c81d29 ("mips_malta: provide ememsize env variable to
kernels") changed the meaning of loaderparams.ram_size to be the whole
of RAM rather than just the low part below where the boot code is placed
for KVM, but it didn't update the PC initialisation for KVM to use
ram_low_size. Fix that now.

monitor: Throttle event VSERPORT_CHANGE separately by "id"
VSERPORT_CHANGE is emitted when the guest opens or closes a
virtio-serial port. The event's member "id" identifies the port.
When several events arrive quickly, throttling drops all but the last
of them. Because of that, a QMP client must assume that *any* port
may have changed state when it receives a VSERPORT_CHANGE event and
throttling may have happened.
Make the event more useful by throttling it for each port separately.

whether there were any requests pending, but it ignored other children.
There's no need to special case file and backing here, so just replace
these two explicit recursions by a loop recursing for all child nodes.

virtio: sync the dataplane vring state to the virtqueue before virtio_save
When creating snapshot with the dataplane enabled, the snapshot file gets
not the actual state of virtqueue, because the current state is stored in
VirtIOBlockDataPlane. Therefore, before saving snapshot need to sync
the dataplane vring state to the virtqueue. The dataplane will resume its
work at the next notify virtqueue.
When snapshot loads with loadvm we get a message:
VQ 0 size 0x80 Guest index 0x15f5 inconsistent with Host index 0x0:
delta 0x15f5
error while loading state for instance 0x0 of device
'0000:00:08.0/virtio-blk'
Error -1 while loading VM state
to reproduce the error I used the following hmp commands:
savevm snap1
loadvm snap1

Devices that are compliant with virtio-1 do not support scsi

qemu-gdb: allow using glibc_pointer_guard() on core dumps
get_fs_base() cannot be run on a core dump, because it uses the arch_prctl
system call. The fs base is the value that is returned by pthread_self(),
and it would be nice to just glean it from the "info threads" output:
* 1 Thread 0x7f16a3fff700 (LWP 33642) pthread_cond_wait@@GLIBC_2.3.2 ()
^^^^^^^^^^^^^^
but unfortunately the gdb API does not provide that. Instead, we can
look for the "arg" argument of the start_thread function if glibc debug
information are available. If not, fall back to the old mechanism.

target-mips: implement the CPU wake-up on non-enabled interrupts in R6
In Release 6, the behaviour of WAIT has been modified to make it a
requirement that a processor that has disabled operation as a result of
executing a WAIT will resume operation on arrival of an interrupt even if
interrupts are not enabled.

On event: send event, arm timer, goto state 2
State 2: Event sent recently, no additional event being delayed
Invariant: evstate->timer is pending, evstate->qdict is null
On event: store it in evstate->qdict, goto state 3
On timer: goto state 1
State 3: Event sent recently, additional event being delayed
Invariant: evstate->timer is pending, evstate->qdict is non-null
On event: store it in evstate->qdict, goto state 3
On timer: send evstate->qdict, clear evstate->qdict,
arm timer, goto state 2

This enables hotplug for multifunction devices.
Patches are very small, so I think it's OK to merge
at this stage.
There's also some new infrastructure for vhost-user testing
not enabled yet so it's harmless to merge.
I've reverted the "gap between DIMMs" workaround, as it seems too risky, and
applied my own patch in virtio, but not in dataplane code. This means that
dataplane is broken for some complex DIMM configurations for now. Waiting for

tests/vhost-user-bridge: add vhost-user bridge application
The test existing in QEMU for vhost-user feature is good for
testing the management protocol, but does not allow actual
traffic. This patch proposes Vhost-User Bridge application, which
can serve the QEMU community as a comprehensive test by running
real internet traffic by means of vhost-user interface.
Essentially the Vhost-User Bridge is a very basic vhost-user
backend for QEMU. It runs as a standalone user-level process.
For packet processing Vhost-User Bridge uses an additional QEMU
instance with a backend configured by "-net socket" as a shared
VLAN. This way another QEMU virtual machine can effectively
serve as a shared bus by means of UDP communication.
For a more simple setup, the another QEMU instance running the
SLiRP backend can be the same QEMU instance running vhost-user
client.
This Vhost-User Bridge implementation is very preliminary. It is
missing many features. I has been studying vhost-user protocol
internals, so I've written vhost-user-bridge bit by bit as I
progressed through the protocol. Most probably its internal
architecture will change significantly.
To run Vhost-User Bridge application:
1. Build vhost-user-bridge with a regular procedure. This will
create a vhost-user-bridge executable under tests directory:
$ configure; make tests/vhost-user-bridge
2. Ensure the machine has hugepages enabled in kernel with
command line like:
default_hugepagesz=2M hugepagesz=2M hugepages=2048
3. Run Vhost-User Bridge with:
$ tests/vhost-user-bridge
The above will run vhost-user server listening for connections
on UNIX domain socket /tmp/vubr.sock, and will try to connect
by UDP to VLAN bridge to localhost:5555, while listening on
localhost:4444
Run qemu with a virtio-net backed by vhost-user:
$ qemu \
-enable-kvm -m 512 -smp 2 \
-object memory-backend-file,id=mem,size=512M,mem-path=/dev/hugepages,share=on \
-numa node,memdev=mem -mem-prealloc \
-chardev socket,id=char0,path=/tmp/vubr.sock \
-netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce \
-device virtio-net-pci,netdev=mynet1 \
-net none \
-net socket,vlan=0,udp=localhost:4444,localaddr=localhost:5555 \
-net user,vlan=0 \
disk.img
vhost-user-bridge was tested very lightly: it's able to bringup a
linux on client VM with the virtio-net driver, and execute transmits
and receives to the internet. I tested with "wget redhat.com",
"dig redhat.com".
PS. I've consulted DPDK's code for vhost-user during Vhost-User
Bridge implementation.

virtio: introduce virtio_map
virtio_map_sg currently fails if one of the entries it's mapping is
contigious in GPA but not HVA address space. Introduce virtio_map which
handles this by splitting sg entries.
This new API generally turns out to be a good idea since it's harder to
misuse: at least in one case the existing one was used incorrectly.
This will still fail if there's no space left in the sg, but luckily max
queue size in use is currently 256, while max sg size is 1024, so we
should be OK even is all entries happen to cross a single DIMM boundary.
Won't work well with very small DIMM sizes, unfortunately:
e.g. this will fail with 4K DIMMs where a single
request might span a large number of DIMMs.
Let's hope these are uncommon - at least we are not breaking things.
Note: virtio-scsi calls virtio_map_sg on data loaded from network, and
validates input, asserting on failure. Copy the validating code here -
it will be dropped from virtio-scsi in a follow-up patch.

pc: memhp: do not emit inserting event for coldplugged DIMMs
currently acpi_memory_plug_cb() sets is_inserting for
cold- and hot-plugged DIMMs as result ASL MHPD.MSCN()
method issues device check even for every coldplugged
DIMM. There isn't much harm in it but if we try to
unplug such DIMM, OSPM will issue device check
intstead of device eject event. So OSPM won't eject
memory module as expected and it will try to eject it
only when another memory device is hot-(un)plugged.
As a fix do not set 'is_inserting' event and do not
issue SCI for cold-plugged DIMMs as they are
enumerated and activated by OSPM during guest's boot.

Author: Eduardo Habkost <ehabkost@redhat.com>

target-i386: Enable "check" mode by default
Current default behavior of QEMU is to silently disable features that
are not supported by the host when a CPU model is requested in the
command-line. This means that in addition to risking breaking guest ABI
by default, we are silent about it.
I would like to enable "enforce" by default, but this can easily break
existing production systems because of the way libvirt makes assumptions
about CPU models today (this will change in the future, once QEMU
provide a proper interface for checking if a CPU model is runnable).
But there's no reason we should be silent about it. So, change
target-i386 to enable "check" mode by default so at least we have some
warning printed to stderr (and hopefully logged somewhere) when QEMU
disables a feature that is not supported by the host system.

target-i386: Don't left shift negative constant
Left shift of negative values is undefined behavior. Detected by clang:
qemu/target-i386/translate.c:2423:26: runtime error:

This changes the code to reverse the sign after the left shift.

hw/arm/virt: don't use a15memmap directly
We should always go through VirtBoardInfo when we need the memmap.
To avoid using a15memmap directly, in this case, we need to defer
the max-cpus check from class init time to instance init time. In
class init we now use MAX_CPUMASK_BITS for max_cpus initialization,
which is the maximum QEMU supports, and also, incidentally, the
maximum KVM/gicv3 currently supports. Also, a nice side-effect of
delaying the max-cpus check is that we now get more appropriate
error messages for gicv2 machines that try to configure more than
123 cpus. Before this patch it would complain that the requested
number of cpus was greater than 123, but for gicv2 configs, it
should complain that the number is greater than 8.

anything. This will result in a broken machine state.

target-arm/translate.c: Handle non-executable page-straddling Thumb insns
When the memory we're trying to translate code from is not executable we have
to turn this into a guest fault. In order to report the correct PC for this
fault, and to make sure it is not reported until after any other possible
faults for instructions earlier in execution, we must terminate TBs at
the end of a page, in case the next instruction is in a non-executable page.
This is simple for T16, A32 and A64 instructions, which are always aligned
to their size. However T32 instructions may be 32-bits but only 16-aligned,
so they can straddle a page boundary.
Correct the condition that checks whether the next instruction will touch
the following page, to ensure that if we're 2 bytes before the boundary
and this insn is T32 then we end the TB.

target-arm: Fix "no 64-bit EL2" assumption in arm_excp_unmasked()
The code in arm_excp_unmasked() suppresses the ability of PSTATE.AIF
to mask exceptions from a lower EL targeting EL2 or EL3 if the
CPU is 64-bit. This is correct for a target of EL3, but not correct
for targeting EL2. Further, we go to some effort to calculate
scr and hcr values which are not used at all for the 64-bit CPU
case.
Rearrange the code to correctly implement the 64-bit CPU logic
and keep the hcr/scr calculations in the 32-bit CPU codepath.

net: Remove duplicate data from query-rx-filter on multiqueue net devices
When responding to a query-rx-filter command on a multiqueue
netdev, qemu reports the data for each queue. The data, however,
is not per-queue, but per device and the same data is reported
multiple times. This causes confusion and may also cause extra
unnecessary processing when looking at the data.
Commit 638fb14169 (net: Make qmp_query_rx_filter() with name argument
more obvious) partially addresses this issue, by limiting the output
when the name is specified. However, when the name is not specified,
the issue still persists.

vmxnet3: Do not fill stats if device is inactive
Guest OS may issue VMXNET3_CMD_GET_STATS even before device was
activated (for example in linux, after insmod but prior net-dev open).
Accessing shared descriptors prior device activation is illegal as the
VMXNET3State structures have not been fully initialized.
As a result, guest memory gets corrupted and may lead to guest OS
crashes.
Fix, by not filling the stats descriptors if device is inactive.

Qemu/Xen: Fix early freeing MSIX MMIO memory region
msix->mmio is added to XenPCIPassthroughState's object as property.
object_finalize_child_property is called for XenPCIPassthroughState's
object, which calls object_property_del_all, which is going to try to
delete msix->mmio. object_finalize_child_property() will access
msix->mmio's obj. But the whole msix struct has already been freed
by xen_pt_msix_delete. This will cause segment fault when msix->mmio
has been overwritten.
This patch is to fix the issue.

ivshmem: use little-endian int64_t for the protocol
The current ivshmem protocol uses 'long' for integers. But the
sizeof(long) depends on the host and the endianess is not defined, which
may cause portability troubles.
Instead, switch to using little-endian int64_t. This breaks the
protocol, except on x64 little-endian host where this change
should be compatible.

state->bs is assigned right after bdrv_drained_begin. Because it was
used as the flag for deletion or not in abort, now we need a separate

The reason the status of the guest device is taken into account is
because once the guest device's tray is opened, any request on the same

block/throttle-groups: Make incref/decref public
Throttle groups are not necessarily referenced by BDSs alone; a later
patch will essentially allow BBs to reference them, too. Make the
ref/unref functions public so that reference can be properly accounted
for.
Their interface is slightly adjusted in that they return and take a
ThrottleState pointer, respectively, instead of a ThrottleGroup pointer.
Functionally, they are equivalent, but since ThrottleGroup is not meant
to be used outside of block/throttle-groups.c, ThrottleState is easier
to handle.

block: Remove wr_highest_sector from BlockAcctStats
BlockAcctStats contains statistics about the data transferred from and
to the device; wr_highest_sector does not fit in with the rest.
Furthermore, those statistics are supposed to be specific for a certain
device and not necessarily for a BDS (see the comment above
bdrv_get_stats()); on the other hand, wr_highest_sector may be a rather
important information to know for each BDS. When BlockAcctStats is
finally removed from the BDS, we will want to keep wr_highest_sector in
the BDS.
Finally, wr_highest_sector is renamed to wr_highest_offset and given the
appropriate meaning. Externally, it is represented as an offset so there
is no point in doing something different internally. Its definition is
changed to match that in qapi/block-core.json which is "the offset after
the greatest byte written to". Doing so should not cause any harm since
if external programs tried to calculate the volume usage by
(wr_highest_offset + 512) / volume_size, after this patch they will just
assume the volume to be full slightly earlier than before.

block: Fix BB AIOCB AioContext without BDS
Fix the BlockBackend's AIOCB AioContext for aborting AIO in case there
is no BDS. If there is no implementation of AIOCBInfo::get_aio_context()
the AioContext is derived from the BDS the AIOCB belongs to. If that BDS
is NULL (because it has been removed from the BB) this will not work.
This patch makes blk_get_aio_context() fall back to the main loop
context if the BDS pointer is NULL and implements
AIOCBInfo::get_aio_context() (blk_aiocb_get_aio_context()) which invokes
blk_get_aio_context().

tests: test-qga, loosen assumptions about host filesystems
QGA skips pseudo-filesystems when querying filesystems via
guest-get-fsinfo. On some hosts, such as travis-ci which uses
containers with simfs filesystems, QGA might not report *any*
filesystems. Our test case assumes there would be at least one,
leading to false error messages in these situations.
Instead, sanity-check values iff we get at least one filesystem.

spapr_pci: Allow VFIO devices to work on the normal PCI host bridge
The core VFIO infrastructure more or less allows VFIO devices to work
on any normal guest PCI host bridge (PHB) without extra logic.
However, the "spapr-pci-host-bridge" device (as opposed to the special
"spapr-pci-vfio-host-bridge" device) breaks this by using a partially
KVM accelerated implementation of the guest kernel IOMMU which won't
work with VFIO devices, without additional kernel support.
This patch allows VFIO devices to work on the spapr-pci-host-bridge,
by having it switch off KVM TCE acceleration when a VFIO device is
added to the PHB (either on startup, or by hotplug).

spapr_iommu: Provide a function to switch a TCE table to allowing VFIO
Because of the way non-VFIO guest IOMMU operations are KVM accelerated, not
all TCE tables (guest IOMMU contexts) can support VFIO devices. Currently,
this is decided at creation time.
To support hotplug of VFIO devices, we need to allow a TCE table which
previously didn't allow VFIO devices to be switched so that it can. This
patch adds an spapr_tce_set_need_vfio() function to do this, by
reallocating the table in userspace if necessary.
Currently this doesn't allow the KVM acceleration to be re-enabled if all
the VFIO devices are removed. That's an optimization for another time.

The vfio_accel parameter used when creating a new TCE table (guest IOMMU
context) has a confusing name. What it really means is whether we need the
TCE table created to be able to support VFIO devices.
VFIO is relevant, because when available we use in-kernel acceleration of
the TCE table, but that may not work with VFIO devices because updates to
the table are handled in kernel, bypass qemu and so don't hit qemu's
infrastructure for keeping the VFIO host IOMMU state in sync with the guest
IOMMU state.
Rename the parameter to "need_vfio" throughout. This is a cosmetic change,
with no impact on the logic.

spapr_pci: Allow PCI host bridge DMA window to be configured
At present the PCI host bridge (PHB) for the pseries machine type has a
fixed DMA window from 0..1GB (in PCI address space) which is mapped to real
memory via the PAPR paravirtualized IOMMU.
For better support of VFIO devices, we're going to want to allow for
different configurations of the DMA window.
Eventually we'll want to allow the guest itself to reconfigure the window
via the PAPR dynamic DMA window interface, but as a preliminary this patch
allows the user to reconfigure the window with new properties on the PHB
device.

spapr: Add "slb-size" property to CPU device tree nodes
According to a commit message in the Linux kernel (see here
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b60c31d85a2a
for example), the name of the property that carries the information
about the number of SLB entries should be called "slb-size", and
not "ibm,slb-size". The Linux kernel can deal with both names, but
to be on the safe side we should support the official name, too.
[Now that LoPAPR is public, the relevant requirement can be found in
section C.6.1.8 --dwg]

crypto: add sanity checking of TLS x509 credentials
defined new variables $TEST_LIBS and $TEST_CFLAGS and
used them in tests/Makefile to augment $LIBS and $CFLAGS.
Unfortunately this overlooks the fact that tests/Makefile
is not executed via recursive-make, it is just pulled into
the top level Makefile via an include statement. So rather
than just augmenting the compiler/linker flags for tests
it polluted the global flags.
This is thought to be behind a reported failure when
building the pixman module as a sub-module, since global
$CFLAGS are passed down to configure in pixman.
This change removes the $TEST_LIBS and $TEST_CFLAGS
replacing them with $TASN1_LIBS and $TASN1_CFLAGS,
setting only against specific objects/executables
that need them.

crypto: allow use of nettle/gcrypt to be selected explicitly
Currently the choice of whether to use nettle or gcrypt is
made based on what gnutls is linked to. There are times
when it is desirable to be able to force build against a
specific library. For example, if testing changes to QEMU's
crypto code all 3 possible backends need to be checked
regardless of what the local gnutls uses.
It is also desirable to be able to enable nettle/gcrypt
for cipher/hash algorithms, without enabling gnutls
for TLS support.
This gives two new configure flags, which allow the
following possibilities
Automatically determine nettle vs gcrypt from what
gnutls links to (recommended to minimize number of
crypto libraries linked to)
./configure
Automatically determine nettle vs gcrypt based on
which is installed
./configure --disable-gnutls
Force use of nettle
./configure --enable-nettle
Force use of gcrypt
./configure --enable-gcrypt
Force use of built-in AES & crippled-DES
./configure --disable-nettle --disable-gcrypt

hw/isa/lpc_ich9: inject the SMI on the VCPU that is writing to APM_CNT
Commit 4d00636e97b7 ("ich9: Add the lpc chip", Nov 14 2012) added the
ich9_apm_ctrl_changed() ioport write callback function such that it would
inject the SMI, in response to a write to the APM_CNT register, on the
first CPU, invariably.
Since this register is used by guest code to trigger an SMI synchronously,
the interrupt should be injected on the VCPU that is performing the write.
apm_ioport_writeb() is the .write callback of the "apm_ops"
MemoryRegionOps [hw/isa/apm.c]; it is parametrized to call
ich9_apm_ctrl_changed() by ich9_lpc_init() [hw/isa/lpc_ich9.c], via
apm_init(). Therefore this change affects no other board.
ich9_generate_smi() is an unrelated function that is called by the TCO
watchdog; a watchdog is likely in its right to (asynchronously) inject
interrupts on the first CPU only.
This patch allows the combined edk2/OVMF SMM driver stack to work with
multiple VCPUs on TCG, using both qemu-system-i386 and qemu-system-x86_64.

vhost: set the correct queue index in case of migration with multiqueue
When a live migration is started the log address to mark dirty pages is provided
to the vhost backend through the vhost_dev_set_log function.
This function is called for each queue pairs but the queue index is wrongly set:
always set to the first queue pair. Then vhost backend lost descriptor addresses
of the queue pairs greater than 1 and behaviour of the vhost backend is
unpredictable.
The queue index is computed by taking account of the vq_index (to retrieve the
queue pair index) and calling the vhost_get_vq_index method of the backend.

vhost user: add rarp sending after live migration for legacy guest
A new vhost user message is added to allow QEMU to ask to vhost user backend to
broadcast a fake RARP after live migration for guest without GUEST_ANNOUNCE
capability.
This new message is sent only if the backend supports the new
VHOST_USER_PROTOCOL_F_RARP protocol feature.
The payload of this new message is the MAC address of the guest (not known by
the backend). The MAC address is copied in the first 6 bytes of a u64 to avoid
to create a new payload message type.
This new message has no equivalent ioctl so a new callback is added in the
userOps structure to send the request.
Upon reception of this new message the vhost user backend must generate and
broadcast a fake RARP request to notify the migration is terminated.

vhost user: add support of live migration
Some vhost user backends are able to support live migration.
To provide this service the following features must be added:
1. Add the VIRTIO_NET_F_GUEST_ANNOUNCE capability to vhost-net when netdev
backend is vhost-user.
2. Provide a nop receive callback to vhost-user.
This callback is called by:
* qemu_announce_self after a migration to send fake RARP to avoid network
outage for peers talking to the migrated guest.
- For guest with GUEST_ANNOUNCE capabilities, guest already sends GARP
when the bit VIRTIO_NET_S_ANNOUNCE is set.
=> These packets must be discarded.
- For guest without GUEST_ANNOUNCE capabilities, migration termination
is notified when the guest sends packets.
=> These packets can be discarded.
* virtio_net_tx_bh with a dummy boot to send fake bootp/dhcp request.
BIOS guest manages virtio driver to send 4 bootp/dhcp request in case of
dummy boot.
=> These packets must be discarded.

util: add linux-only memfd fallback
Implement memfd_create() fallback if not available in system libc.
memfd_create() is still not included in glibc today, atlhough it's been
available since Linux 3.17 in Oct 2014.
memfd has numerous advantages over traditional shm/mmap for ipc memory
sharing with fd handler, which we are going to make use of for
vhost-user logging memory in following patches.
The next patches are going to introduce helpers to use best practices of
memfd usage and provide some compatibility fallback. memfd.c is thus
temporarily useless and eventually empty if memfd_create() is provided
by the system.

XTFPGA FLASH is tied to XTFPGA system IO block. It's not very important

Map XTFPGA FLASH to system IO block and fix offsets used for mapping.

s390x/cmma: clean up cmma reset
The cmma reset is per VM, so we don't need a cpu object. We can
directly make use of kvm_state, as it is already available when
the reset is called. By moving the cmma reset in our machine reset
function, we can avoid a manual reset handler.

s390x: reset crypto only on clear reset and QEMU reset
Initializing VM crypto in initial cpu reset has multiple problems
1. We call the exact same function #VCPU times, although one time is enough
2. On SIGP initial cpu reset, we exchange the wrapping key while
other VCPUs are running. Bad!
3. It is simply wrong. According to the Pop, a reset happens only during a
clear reset.
So, we have to reset the keys
- on modified clear reset
- on load clear (QEMU reset - via machine reset)
- on qemu start (via machine reset)

s390x: machine reset function with new ipl cpu handling
Current implementation depends on the order of resets getting triggered.
If a cpu reset is triggered after the ipl device reset, the CPU is stopped and
the VM will not run. In fact, that hinders us from converting the ipl device
into a TYPE_DEVICE. Let's change that by manually configuring the ipl cpu
during a system reset, so we have full control and can demangle that code.
Also remove the superflous cpu parameter from s390_update_iplstate on the way.

vhost-net: tell tap backend about the vnet endianness

ioctl if it matches the host endian-ness.

Device hotplugs trigger a crw machine check. All machine checks

This is a band-aid suitable for stable. Long term we should
create the full mcic value dynamically depending on the active
features in the kernel interrupt handler.

coroutine: move into libqemuutil.a library
The coroutine files are currently referenced by the block-obj-y
variable. The coroutine functionality though is already used by
more than just the block code. eg migration code uses coroutine
yield. In the future the I/O channel code will also use the
coroutine yield functionality. Since the coroutine code is nicely
self-contained it can be easily built as part of the libqemuutil.a
library, making it widely available.
The headers are also moved into include/qemu, instead of the
include/block directory, since they are now part of the util
codebase, and the impl was never in the block/ directory
either.

osdep: add qemu_fork() wrapper for safely handling signals
When using regular fork() the child process of course inherits
all the parents' signal handlers. If the child then proceeds
to close() any open file descriptors, it may break some of those
registered signal handlers. The child generally does not want to
ever run any of the signal handlers that the parent may have
installed in the short time before it exec's. The parent may also
have blocked various signals which the child process will want
enabled.
This introduces a wrapper qemu_fork() that takes care to sanitize
signal handling across fork. Before forking it blocks all signals
in the parent thread. After fork returns, the parent unblocks the
signals and carries on as usual. The child, however, resets all the
signal handlers back to their defaults before it unblocks signals.
The child process can now exec the binary in a "clean" signal
environment.

Glib portable GIOChannel is used for data I/O.
Optinal stdin parameter of guest-exec command is now used as
stdin content for spawned subprocess.
If capture-output bool flag is specified, guest-exec redirects out/err
file descriptiors internally to pipes and collects subprocess
output.
Guest-exe-status is modified to return this collected data to requestor
in base64 encoding.

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,

Two, it returns T * rather than void *, which lets the compiler catch

build: qemu-ga: add 'qemu-ga' build target for w32
Currently POSIX builds rely on 'qemu-ga' target to do qga-only
distributable build. On w32, as with most standalone binary targets,
we rely on 'qemu-ga.exe' target.
Unlike with POSIX, qemu-ga for w32 has a number of related targets
such as VSS DLL and MSI package. We can do the full distributable
qga-only build on w32 with:
make qemu-ga.exe
or:
make msi
To make that work, we tie VSS dependencies onto qemu-ga.exe.
However, in reality the DLL isn't part of the binary, so we use a
filter to pull them out of the LINK recipe, which attempts to link
against prereqs for binary targets. Additionally, it could be argued
that VSS is a separate distributable, and shouldn't be implied by
qemu-ga.exe binary target.
To avoid this, we can tie the VSS dependencies only to the 'msi'
target, but that would make it impossible to do a qga-only build of
the w32 distributable without building the 'msi' package, which was
supported in the past.
An alternative approach is to add a new target to build the whole
distributable. w32 allows us to use the same build target we use
on POSIX, 'qemu-ga', since the current binary-only target on w32
is 'qemu-ga.exe'.
To further simplify the build, we also make 'qemu-ga' build the MSI
package if the appropriate ./configure options are set, making the
full qga-only build the same on both POSIX and w32: `make qemu-ga`

tcg/mips: Support r6 SEL{NE, EQ}Z instead of MOVN/MOVZ
Extend MIPS movcond implementation to support the SELNEZ/SELEQZ
instructions introduced in MIPS r6 (where MOVN/MOVZ have been removed).
Whereas the "MOVN/MOVZ rd, rs, rt" instructions have the following
semantics:
rd = [!]rt ? rs : rd
The "SELNEZ/SELEQZ rd, rs, rt" instructions are slightly different:
rd = [!]rt ? rs : 0
First we ensure that if one of the movcond input values is zero that it
comes last (we can swap the input arguments if we invert the condition).
This is so that it can exactly match one of the SELNEZ/SELEQZ
instructions and avoid the need to emit the other one.
Otherwise we emit the opposite instruction first into a temporary
register, and OR that into the result:
SELNEZ/SELEQZ TMP1, v2, c1
SELEQZ/SELNEZ ret, v1, c1
OR ret, ret, TMP1
Which does the following:
ret = cond ? v1 : v2

tcg/mips: Support r6 multiply/divide encodings
MIPSr6 adds several new integer multiply, divide, and modulo
instructions, and removes several pre-r6 encodings, along with the HI/LO
registers which were the implicit operands of some of those
instructions. Update TCG to use the new instructions when built for r6.
The new instructions actually map much more directly to the TCG ops, as
they only provide a single 32-bit half of the result and in a normal
general purpose register instead of HI or LO.
The mulu2_i32 and muls2_i32 operations are no longer appropriate for r6,
so they are removed from the TCG opcode table. This is because they
would need to emit two separate host instructions anyway (for the high
and low half of the result), which TCG can arrange automatically for us
in the absense of mulu2_i32/muls2_i32 by splitting it into mul_i32 and
mul*h_i32 TCG ops.

kvm: Allow the Hyper-V vendor ID to be specified
According to Microsoft documentation, the signature in the standard
hypervisor CPUID leaf at 0x40000000 identifies the Vendor ID and is
for reporting and diagnostic purposes only. We can therefore allow
the user to change it to whatever they want, within the 12 character
limit. Add a new hv-vendor-id option to the -cpu flag to allow
for this, ex:
-cpu host,hv_time,hv-vendor-id=KeenlyKVM

kvm: Pass PCI device pointer to MSI routing functions
In-kernel ITS emulation on ARM64 will require to supply requester IDs.
These IDs can now be retrieved from the device pointer using new
pci_requester_id() function.
This patch adds pci_dev pointer to KVM GSI routing functions and makes
callers passing it.
x86 architecture does not use requester IDs, but hw/i386/kvm/pci-assign.c
also made passing PCI device pointer instead of NULL for consistency with
the rest of the code.

hw/pci: Introduce pci_requester_id()
For GICv3 ITS implementation we are going to use requester IDs in KVM IRQ
routing code. This patch introduces reusable convenient way to obtain this
ID from the device pointer. The new function is now used in some places,
where the same calculation was used.
MemTxAttrs.stream_id also renamed to requester_id in order to better
reflect semantics of the field.

intel_iommu: Add support for translation for devices behind bridges
- Use a hash table indexed on bus pointers to store information about buses
instead of using the bus numbers.
Bus pointers are stored in a new VTDBus struct together with the vector
of device address space pointers indexed by devfn.
- The bus number is still used for lookup for selective SID based invalidate,
in which case the bus number is lazily resolved from the bus hash table and
cached in a separate index.

target-arm: Fix CPU breakpoint handling
A QEMU breakpoint match is not definitely an architectural breakpoint
match. If an exception is generated unconditionally during translation,
it is hardly possible to ignore it in the debug exception handler.

blkdebug: Don't confuse image as backing file

qemu-nbd: always compile in --aio=MODE option
The --aio=MODE option enables Linux AIO or Windows overlapped I/O.
The #ifdef CONFIG_LINUX_AIO was a layering violation that also prevented
Windows overlapped I/O from being used.
Now that raw-posix.c prints an error when Linux AIO has not been
compiled in, we can unconditionally compile the option into qemu-nbd.
After this patch qemu-nbd --aio=native works on Windows.

util - add automated ID generation utility
Multiple sub-systems in QEMU may find it useful to generate IDs
for objects that a user may reference via QMP or HMP. This patch
presents a standardized way to do it, so that automatic ID generation
follows the same rules.
This patch enforces the following rules when generating an ID:
1.) Guarantee no collisions with a user-specified ID
2.) Identify the sub-system the ID belongs to
3.) Guarantee of uniqueness
4.) Spoiling predictability, to avoid creating an assumption
of object ordering and parsing (i.e., we don't want users to think
they can guess the next ID based on prior behavior).
The scheme for this is as follows (no spaces):
# subsys D RR
Reserved char --| | | |
Subsystem String ----| | |
Unique number (64-bit) --| |
Two-digit random number ---|
For example, a generated node-name for the block sub-system may look
like this:
#block076
The caller of id_generate() is responsible for freeing the generated
node name string with g_free().

This cleans up the mess we left behind in the mirror code after the

The interface change of the mirror job that callers must consider is
that after job completion, their local BDS pointers still point to the
same node now. qemu-img must change its code accordingly (which makes it
easier to understand); the other callers stays unchanged because after
completion they don't do anything with the BDS, but just with the job,
and the job is still owned by the source BDS.

blockjob: Store device name at job creation
Some block jobs change the block device graph on completion. This means
that the device that owns the job and originally was addressed with its
device name may no longer be what the corresponding BlockBackend points
to.
Previously, the effects of bdrv_swap() ensured that the job was (at
least partially) transferred to the target image. Events that contain
the device name could still use bdrv_get_device_name(job->bs) and get
the same result.
After removing bdrv_swap(), this won't work any more. Instead, save the
device name at job creation and use that copy for QMP events and
anything else identifying the job.

block: Implement bdrv_append() without bdrv_swap()
Remember all parent nodes and just change the pointers there instead of
swapping the contents of the BlockDriverState.
Handling of snapshot=on must be moved further down in bdrv_open()
because *pbs (which is the bs pointer in the BlockBackend) must already
be set before bdrv_append() is called. Otherwise bdrv_append() changes
the BB's pointer to the temporary snapshot, but bdrv_open() overwrites
it with the read-only original image.
We also need to be careful to update callers as the interface changes
(becomes less insane): Previously, the meaning of the two parameters was
inverted when bdrv_append() returns. Now any BDS pointers keep pointing
to the same node.

Since we cannot guarantee that abort() will produce a core dump, we
should use SIGKILL instead (that does not produce any) and update the

hw/arm/virt: smbios: inform guest of kvm
ARM/AArch64 KVM guests don't have any way to identify
themselves as KVM guests (x86 guests use a CPUID leaf). Now, we
could discuss all sorts of reasons why guests shouldn't need to
know that, but then there's always some case where it'd be
nice... Anyway, now that we have SMBIOS tables in ARM guests,
it's easy for the guest to know that it's a QEMU instance. This
patch takes that one step further, also identifying KVM, when
appropriate. Again, we could debate why generally nothing
should care whether it's of type QEMU or QEMU/KVM, but again,
sometimes it's nice to know...

target-arm: Break the TB after ISB to execute self-modified code correctly
If any store instruction writes the code inside the same TB
after this store insn, the execution of the TB must be stopped
to execute new code correctly.
As described in ARMv8 manual D3.4.6 self-modifying code must do an
IC invalidation to be valid, and an ISB after it. So it's enough to end
the TB after ISB instruction on the code translation.
Also this TB break is necessary to take any pending interrupts immediately
after an ISB (as required by ARMv8 ARM D1.14.4).

qapi: Track location that created an implicit type
A future patch will move some error checking from the parser
to the various QAPISchema*.check() methods, which run only
after parsing completes. It will thus be possible to create
a python instance representing an implicit QAPI type that
parses fine but will fail validation during check(). Since
all errors have to have an associated 'info' location, we
need a location to be associated with those implicit types.
The intuitive info to use is the location of the enclosing
entity that caused the creation of the implicit type.
Note that we do not anticipate builtin types being used in
an error message (as they are not part of the user's QAPI
input, the user can't cause a semantic error in their
behavior), so we exempt those types from requiring info, by
setting a flag to track the completion of _def_predefineds(),
and tracking that flag in _def_entity().
No change to the generated code.

qapi: Create simple union type member earlier
For simple unions, we were creating the implicit 'type' tag
member during the QAPISchemaObjectTypeVariants constructor.
This is different from every other implicit QAPISchemaEntity
object, which get created by QAPISchema methods. Hoist the
creation to the caller (renaming _make_tag_enum() to
_make_implicit_tag()), and pass the entity rather than the
string name, so that we have the nice property that no
entities are created as a side effect within a different
entity. A later patch will then have an easier time of
associating location info with each entity creation.

qapi: Lazy creation of array types
Commit ac88219a had several TODO markers about whether we needed
to automatically create the corresponding array type alongside
any other type. It turns out that most of the time, we don't!
There are a few exceptions: 1) We have a few situations where we
use an array type in internal code but do not expose that type
through QMP; fix it by declaring a dummy type that forces the
generator to see that we want to use the array type.
2) The builtin arrays (such as intList for QAPI ['int']) must
always be generated, because of the way our QAPI_TYPES_BUILTIN
compile guard works: we have situations (at the very least
tests/test-qmp-output-visitor.c) that include both top-level
"qapi-types.h" (via "error.h") and a secondary
"test-qapi-types.h". If we were to only emit the builtin types
when used locally, then the first .h file would not include all
types, but the second .h does not declare anything at all because
the first .h set QAPI_TYPES_BUILTIN, and we would end up with
compilation error due to things like unknown type 'int8List'.
Actually, we may need to revisit how we do type guards, and
change from a single QAPI_TYPES_BUILTIN over to a different
usage pattern that does one #ifdef per qapi type - right now,
the only types that are declared multiple times between two qapi
.json files for inclusion by a single .c file happen to be the
builtin arrays. But now that we have QAPI 'include' statements,
it is logical to assume that we will soon reach a point where
we want to reuse non-builtin types (yes, I'm thinking about what
it will take to add introspection to QGA, where we will want to
reuse the SchemaInfo type and friends). One #ifdef per type
will help ensure that generating the same qapi type into more
than one qapi-types.h won't cause collisions when both are
included in the same .c file; but we also have to solve how to
avoid creating duplicate qapi-types.c entry points. So that
is a problem left for another day.
Generated code for qapi-types and qapi-visit is drastically
reduced; less than a third of the arrays that were blindly
created were actually needed (a quick grep shows we dropped
from 219 to 69 *List types), and the .o files lost more than
30% of their bulk. [For best results, diff the generated
files with 'git diff --patience --no-index pre post'.]
Interestingly, the introspection output is unchanged - this is
because we already cull all types that are not indirectly
reachable from a command or event, so introspection was already
using only a subset of array types. The subset of types
introspected is now a much larger percentage of the overall set
of array types emitted in qapi-types.h (since the larger set
shrunk), but still not 100% (evidence that the array types
emitted for our new Dummy structs, and the new struct itself,
don't affect QMP).

qapi: Don't use info as witness of implicit object type
A future patch will enable error reporting from the various
QAPISchema*.check() methods. But to report an error related
to an implicit type, we'll need to associate a location with
the type (the same location as the top-level entity that is
causing the creation of the implicit type), and once we do
that, keying off of whether foo.info exists is no longer a
viable way to determine if foo is an implicit type.
Instead, add an is_implicit() method to QAPISchemaEntity, and use it.
It can be overridden later for ObjectType and EnumType, when implicit
instances of those classes gain info.

qapi: Prepare for errors during check()
The next few patches will start migrating error checking from
ad hoc parse methods into the QAPISchema*.check() methods. But
for an error message to display, we first have to fix the
overall 'try' to catch those errors. We also want to enable a
few more assertions, such as making sure every attempt to
raise a semantic error is passed a valid location info, or that
various preconditions hold.
The general approach for moving error checking will then be to
relax an assertion into an if that raises an exception if the
condition does not hold, and removing the counterpart ad hoc
check done during the parse phase.

qapi: Use predicate callback to determine visit filtering
Previously, qapi-types and qapi-visit filtered out implicit
objects during visit_object_type() by using 'info' (works since
implicit objects do not [yet] have associated info); meanwhile
qapi-introspect filtered out all schema types on the first pass
by returning a python type from visit_begin(), which was then
used at a distance in QAPISchema.visit() to do the filtering.
Rather than keeping these ad hoc approaches, add a new visitor
callback visit_needed() which returns False to skip a given
entity, and which defaults to True unless overridden. Use the
new mechanism to simplify all three filtering visitors.
No change to the generated code.

synchronize_rcu() waiting for all readers to finish their critical
sections. There is at least one critical section in which we try
to get QGM (critical section is in address_space_rw() and
prepare_mmio_access() is trying to aquire QGM).
Both functions (migration_end() and migration_bitmap_extend())
are called from main thread which is holding QGM.
Thus there is a race condition that ends up with deadlock:
main thread working thread

synchronize_rcu() is |

README: fill out some useful quickstart information
The README file is usually the first thing consulted when a user
or developer obtains a copy of the QEMU source. The current QEMU
README is lacking immediately useful information and so not very
friendly for first time encounters. It either redirects users to
qemu-doc.html (which does not exist until they've actually
compiled QEMU), or the website (which assumes the user has
convenient internet access at time of reading).
This fills out the README file as simple quick-start guide on
the topics of building source, submitting patches, licensing
and how to contact the QEMU community. It does not intend to be
comprehensive, instead referring people to an appropriate web
page to obtain more detailed information. The intent is to give
users quick guidance to get them going in the right direction.

qapi: Simplify gen_visit_fields() error handling

the name of the local variable for error detection, we can
simplify the decision on whether to skip error detection (useful

qapi: Share gen_visit_fields()
Consolidate the code between visit, command marshalling, and
event generation that iterates over the members of a struct.
It reduces code duplication in the generator, so that a future
patch can reduce the size of generated code while touching only
one instead of three locations.
There are no changes to the generated marshal code.
The visitor code becomes slightly more verbose, but remains
semantically equivalent, and is actually easier to read as
it follows a more common idiom:
| visit_optional(v, &(*obj)->has_device, "device", &err);
|- if (!err && (*obj)->has_device) {
|- visit_type_str(v, &(*obj)->device, "device", &err);
|- }
| if (err) {
| goto out;
| }
|+ if ((*obj)->has_device) {
|+ visit_type_str(v, &(*obj)->device, "device", &err);
|+ if (err) {
|+ goto out;
|+ }
|+ }
The event code becomes slightly more verbose, but this is
arguably a bug fix: although the visitors are not well
documented, use of an optional member should not be attempted
unless guarded by a prior call to visit_optional(). Works only
because the output qmp visitor has a no-op visit_optional():
|+ visit_optional(v, &has_offset, "offset", &err);
|+ if (err) {
|+ goto out;
|+ }
| if (has_offset) {
| visit_type_int(v, &offset, "offset", &err);

qapi: Consistent generated code: minimize push_indent() usage
We had some pointless differences in the generated code for visit,
command marshalling, and events; unifying them makes it easier for
future patches to consolidate to common helper functions.
This is one patch of a series to clean up these differences.
This patch reduces the number of push_indent()/pop_indent() pairs
so that generated code is typically already at its natural output
indentation in the python files. It is easier to reason about
generated code if the reader does not have to track how much
spacing will be inserted alongside the code, and moreso when all
of the generators use the same patterns (qapi-type and qapi-event
were already using in-place indentation).
Arguably, the resulting python may be a bit harder to read with C
code at the same indentation as python; on the other hand, not
having to think about push_indent() is a win, and most decent
editors provide syntax highlighting that makes it easier to
visually distinguish python code from string literals that will
become C code.
There is no change to the generated output.

This is one patch of a series to clean up these differences.
This patch names the goto labels 'out' (not 'clean') and 'out_obj'
(not 'out_end'). Additionally, the generator was inconsistent on
whether labels had a leading space [our HACKING is silent; while
emacs 'gnu' style adds the space to avoid littering column 1].
For minimal churn, prefer no leading space; this also matches
the style that is more prevalent in current qemu.git.

Test flat-union-inline is updated to test only one feature
(anonymous branch dictionaries), which can be implemented

qapi: Test use of 'number' within alternates
Add some testsuite exposure for use of a 'number' as part of
an alternate. The current state of the tree has a few bugs
exposed by this: our input parser depends on the ordering of
how the qapi schema declared the alternate, and the parser
does not accept integers for a 'number' in an alternate even
though it does for numbers outside of an alternate.
Mixing 'int' and 'number' in the same alternate is unusual,
since both are supplied by json-numbers, but there does not
seem to be a technical reason to forbid it given that our
json lexer distinguishes between json-numbers that can be
represented as an int vs. those that cannot.
Improve the existing test_visitor_in_alternate() to match the
style of the new test_visitor_in_alternate_number(), and to
ensure full coverage of all possible qtype parsing.

qapi: Add tests for empty unions
The documentation claims that alternates are useful for
allowing two or more types, although nothing enforces this.
Meanwhile, it is silent on whether empty unions are allowed.
In practice, the generated code will compile, in part because
we have a 'void *data' branch; but attempting to visit such a
type will cause an abort(). While there's no technical reason
that a degenerate union could not be made to work, it's harder
to justify the time spent in chasing known (the current
abort() during visit) and unknown corner cases, than it would
be to just outlaw them. A future patch will probably take the
approach of forbidding them; in the meantime, we can at least
add testsuite coverage to make it obvious where things stand.
In addition to adding tests to expose the problems, we also
need to adjust existing tests that are meant to test something
else, but which could fail for the wrong reason if we reject
degenerate alternates/unions.
Note that empty structs are explicitly supported (for example,
right now they are the only way to specify that one branch of a
flat union adds no additional members), and empty enums are
covered by the testsuite as working (even if they do not seem
to have much use).

qapi: Avoid assertion failure on union 'type' collision
The previous commit added two tests that triggered an assertion
failure. It's fairly straightforward to avoid the failure by
just outright forbidding the collision between a union's tag
values and its discriminator name (including the implicit name
'kind' supplied for simple unions [*]). Ultimately, we'd like
to move the collision detection into QAPISchema*.check(), but
for now it is easier just to enhance the existing checks.
[*] Of course, down the road, we have plans to rename the simple
union tag name to 'type' to match the QMP wire name, but the
idea of the collision will still be present even then.
Technically, we could avoid the collision by naming the C union
members representing each enum value as '_case_value' rather
than 'value'; but until we have an actual qapi client (and not
just our testsuite) that has a legitimate reason to match a
case label to the name of a QMP key and needs the name munging
to satisfy the compiler, it's easier to just reject the qapi
as invalid.

qapi: Test for various name collisions
Expose some weaknesses in the generator: we don't always forbid
the generation of structs that contain multiple members that map
to the same C or QMP name. This has already been marked FIXME in
qapi.py in commit d90675f, but having more tests will make sure
future patches produce desired behavior; and updating existing
patches to better document things doesn't hurt, either. Some of
these collisions are already caught in the old-style parser
checks, but ultimately we want all collisions to be caught in the
new-style QAPISchema*.check() methods.
This patch focuses on C struct members, and does not consider
collisions between commands and events (affecting C function
names), or even collisions between generated C type names with
user type names (for things like automatic FOOList struct
representing array types or FOOKind for an implicit enum).
There are two types of struct collisions we want to catch:
1) Collision between two keys in a JSON object. qapi.py prevents
that within a single struct (see test duplicate-key), but it is
possible to have collisions between a type's members and its
base type's members (existing tests struct-base-clash,
struct-base-clash-deep), and its flat union variant members
(renamed test flat-union-clash-member).
2) Collision between two members of the C struct that is generated
for a given QAPI type:
a) Multiple QAPI names map to the same C name (new test
args-name-clash)
b) A QAPI name maps to a C name that is used for another purpose
(new tests flat-union-clash-branch, struct-base-clash-base,
union-clash-data). We already fixed some such cases in commit
0f61af3e and 1e6c1616, but more remain.
c) Two C names generated for other purposes clash
(updated test alternate-clash, new test union-clash-branches,
union-clash-type, flat-union-clash-type)
Ultimately, if we need to have a flat union where a tag value
clashes with a base member name, we could change the generator to
name the union (using 'foo.u.value' rather than 'foo.value') or
otherwise munge the C name corresponding to tag values. But
unless such a need arises, it will probably be easier to just
forbid these collisions.
Some of these negative tests will be deleted later, and positive
tests added to qapi-schema-test.json in their place, when the
generator code is reworked to avoid particular code generation
collisions in class 2).
[Note that viewing this patch with git rename detection enabled
may see some confusion due to renaming some tests while adding
others, but where the content is similar enough that git picks
the wrong pre- and post-patch files to associate]

qapi: Sort qapi-schema tests
Recent changes to qapi have provided quite a bit of churn in
the makefile, because we are inconsistent on what order test
names appear in, and on whether to re-wrap the list of tests or
just add arbitrary line lengths. Writing the list in a sorted
fashion, one test per line, will make future patches easier
to see what tests are being added or removed by a patch.
Although it is tempting to use $(wildcard qapi-schema/*.json)
for a more compact listing, such an approach would risk picking
up leftover garbage .json files in the directory; so keeping
the list explicit is safer for ensuring reproducible tarballs
and test results.

qemu-sockets: fix conversion of ipv4/ipv6 JSON to QemuOpts
The QemuOpts-based code treats "option not set" and "option set
to false" the same way for the ipv4 and ipv6 options, because it
is meant to handle only the ",ipv4" and ",ipv6" substrings in
hand-crafted option parsers.
When converting InetSocketAddress to QemuOpts, however, it is
necessary to handle all three cases (not set, set to true, set
to false). Currently we are not handling all cases correctly.
The rules are:
* if none or both options are absent, leave things as is
* if the single present option is Y, the other should be N.
This can be implemented by leaving things as is, or by setting
the other option to N as done in this patch.
* if the single present option is N, the other should be Y.
This is handled by the "else if" branch of this patch.
This ensures that the ipv4 option has an effect on Windows,
where creating the socket with PF_UNSPEC makes an ipv6
socket. With this patch, ",ipv4" will result in a PF_INET
socket instead.

checkpatch: port fix from kernel "## is not a valid modifier"
checkpatch currently loops on fpu/softfloat.c
Turns out this is fixed in the Linux version of checkpatch.
So this is a port of Andy Whitcrofts fix from Linux,
Original commit was commit 89a883530fe7 ("checkpatch: ## is not a
valid modifier")
As suggested by Peter Maydell for the QEMU version we drop the last "|"
as there seems to be no need for that. (FWIW, the kernel discusion about
that dried out:

kvm-all: Align to qemu_real_host_page_size in kvm_set_phys_mem
As the comment in kvm_set_phys_mem() says, KVM works in page size chunks.
However it uses hardcoded TARGET_PAGE_SIZE which is 4K on most platforms
while actual host may use different page size, for example, PPC64 hosts
use 64K system pages.
This replaces static TARGET_PAGE_SIZE with run-time calculated
qemu_real_host_page_size.

exec.c: Collect AddressSpace related fields into a CPUAddressSpace struct
Gather up all the fields currently in CPUState which deal with the CPU's
AddressSpace into a separate CPUAddressSpace struct. This paves the way
for allowing the CPU to know about more than one AddressSpace.
The rearrangement also allows us to make the MemoryListener a directly
embedded object in the CPUAddressSpace (it could not be embedded in
CPUState because 'struct MemoryListener' isn't defined for the user-only
builds). This allows us to resolve the FIXME in tcg_commit() by going
directly from the MemoryListener to the CPUAddressSpace.
This patch extracts the actual update of the cached dispatch pointer
from cpu_reload_memory_map() (which is renamed accordingly to
cpu_reloading_memory_map() as it is only responsible for breaking
cpu-exec.c's RCU critical section now). This lets us keep the definition
of the CPUAddressSpace struct private to exec.c.

cpu-exec-common.c: Clarify comment about cpu_reload_memory_map()'s RCU operations
The reason for cpu_reload_memory_map()'s RCU operations is not
so much because the guest could make the critical section very
long, but that it could have a critical section within which
it made an arbitrary number of changes to the memory map and
thus accumulate an unbounded amount of memory data structures
awaiting reclamation. Clarify the comment to make this clearer.

exec.c: Don't call cpu_reload_memory_map() from cpu_exec_init()
Currently we call cpu_reload_memory_map() from cpu_exec_init(),
but this is not necessary:
* KVM doesn't use the data structures maintained by
cpu_reload_memory_map() (the TLB and cpu->memory_dispatch)
* for TCG, we will call this function via tcg_commit() either
as soon as tcg_cpu_address_space_init() registers the listener,
or when the first MemoryRegion is added to the AddressSpace
if the AS is empty when we register the listener
The unnecessary call is awkward for adding support for multiple
address spaces per CPU, so drop it.

virtio-blk: use blk_io_plug/unplug for Linux AIO batching
The raw-posix block driver implements Linux AIO batching so multiple
requests can be submitted with a single io_submit(2) system call.
Batching is currently only used by virtio-scsi and
virtio-blk-data-plane.
Enable batching for regular virtio-blk so the number of io_submit(2)
system calls is reduced for workloads with queue depth > 1.
In 4KB random read performance tests with queue depth 32, the CPU
utilization on the host is reduced by 9.4%. The fio job is as follows:
[global]
bs=4k
ioengine=libaio
iodepth=32
direct=1
sync=0
time_based=1
runtime=30
clocksource=gettimeofday
ramp_time=5

rw=randread
filename=/dev/vdb
size=4096M
write_bw_log=fio
write_iops_log=fio
write_lat_log=fio
log_avg_msec=1000
This benchmark was run on an raw image on LVM. The disk was an SSD

You can also use it to crudely simulate network delay. Doesn't
actually delay individual packets, but batches them together, which is
a delay of sorts.
Usage:
-netdev tap,id=bn0
-object filter-buffer,id=f0,netdev=bn0,queue=rx,interval=1000
NOTE:
Interval is in microseconds, it can't be omitted currently, and can't be 0.

This caused crash for valid non-IP packets shorter than 22 bytes, as
'tx_pkt->packet_type' hasn't been assigned for such packets, and
'vmxnet3_on_tx_done_update_stats()' expects it to be properly set.

Revert "qdev: Use qdev_get_device_class() for -device <type>,help"
This reverts commit 31bed5509dfcbdfc293154ce81086a4dbd7a80b6.
The reverted commit changed qdev_device_help() to reject abstract
devices and devices that have cannot_instantiate_with_device_add_yet
set, to fix crash bugs like -device x86_64-cpu,help.
Rejecting abstract devices makes sense: they're purely internal, and
the implementation of the help feature can't cope with them.
Rejecting non-pluggable devices makes less sense: even though you
can't use them with -device, the help may still be useful elsewhere,
for instance with -global. This is a regression: -device FOO,help
used to help even for FOO that aren't pluggable.
The previous two commits fixed the crash bug at a lower layer, so
reverting this one is now safe. Fixes the -device FOO,help
regression, except for the broken devices marked
cannot_even_create_with_object_new_yet. For those, the error message
is improved.
Example of a device where the regression is fixed:
$ qemu-system-x86_64 -device PIIX4_PM,help
PIIX4_PM.command_serr_enable=bool (on/off)
PIIX4_PM.multifunction=bool (on/off)
PIIX4_PM.rombar=uint32
PIIX4_PM.romfile=str
PIIX4_PM.addr=int32 (Slot and optional function number, example: 06.0 or 06)
PIIX4_PM.memory-hotplug-support=bool
PIIX4_PM.acpi-pci-hotplug-with-bridge-support=bool
PIIX4_PM.s4_val=uint8
PIIX4_PM.disable_s4=uint8
PIIX4_PM.disable_s3=uint8
PIIX4_PM.smb_io_base=uint32
Example of a device where it isn't fixed:
$ qemu-system-x86_64 -device host-x86_64-cpu,help
Can't list properties of device 'host-x86_64-cpu'
Both failed with "Parameter 'driver' expects pluggable device type"

qdev: Protect device-list-properties against broken devices
Several devices don't survive object_unref(object_new(T)): they crash
or hang during cleanup, or they leave dangling pointers behind.
This breaks at least device-list-properties, because
qmp_device_list_properties() needs to create a device to find its
properties. Broken in commit f4eb32b "qmp: show QOM properties in
device-list-properties", v2.1. Example reproducer:
$ qemu-system-aarch64 -nodefaults -display none -machine none -S -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 50, "minor": 4, "major": 2}, "package": ""}, "capabilities": []}}
{ "execute": "qmp_capabilities" }
{"return": {}}
{ "execute": "device-list-properties", "arguments": { "typename": "pxa2xx-pcmcia" } }
qemu-system-aarch64: /home/armbru/work/qemu/memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed.
Aborted (core dumped)
[Exit 134 (SIGABRT)]
Unfortunately, I can't fix the problems in these devices right now.
Instead, add DeviceClass member cannot_destroy_with_object_finalize_yet
to mark them:
* Hang during cleanup (didn't debug, so I can't say why):
"realview_pci", "versatile_pci".
* Dangling pointer in cpus: most CPUs, plus "allwinner-a10", "digic",
"fsl,imx25", "fsl,imx31", "xlnx,zynqmp", because they create such
CPUs
* Assert kvm_enabled(): "host-x86_64-cpu", host-i386-cpu",
"host-powerpc64-cpu", "host-embedded-powerpc-cpu",
"host-powerpc-cpu" (the powerpc ones can't currently reach the
assertion, because the CPUs are only registered when KVM is enabled,
but the assertion is arguably in the wrong place all the same)
Make qmp_device_list_properties() fail cleanly when the device is so
marked. This improves device-list-properties from "crashes, hangs or
leaves dangling pointers behind" to "fails". Not a complete fix, just
a better-than-nothing work-around. In the above reproducer,
device-list-properties now fails with "Can't list properties of device
'pxa2xx-pcmcia'".
This also protects -device FOO,help, which uses the same machinery
since commit ef52358 "qdev-monitor: include QOM properties in -device
FOO, help output", v2.2. Example reproducer:
$ qemu-system-aarch64 -machine none -device pxa2xx-pcmcia,help
Before:
qemu-system-aarch64: .../memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed.
After:
Can't list properties of device 'pxa2xx-pcmcia'

tests: Fix how qom-test is run
We want to run qom-test for every architecture, without having to
manually add it to every architecture's list of tests. Commit 3687d53
accomplished this by adding it to every architecture's list
automatically.
However, some architectures inherit their tests from others, like this:
check-qtest-x86_64-y = $(check-qtest-i386-y)
check-qtest-microblazeel-y = $(check-qtest-microblaze-y)
check-qtest-xtensaeb-y = $(check-qtest-xtensa-y)
For such architectures, we ended up running the (slow!) test twice.
Commit 2b8419c attempted to avoid this by adding the test only when
it's not already present. Works only as long as we consider adding
the test to the architectures on the left hand side *after* the ones
on the right hand side: x86_64 after i386, microblazeel after
microblaze, xtensaeb after xtensa.
Turns out we consider them in $(SYSEMU_TARGET_LIST) order. Defined as
SYSEMU_TARGET_LIST := $(subst -softmmu.mak,,$(notdir \
$(wildcard $(SRC_PATH)/default-configs/*-softmmu.mak)))
On my machine, this results in the oder xtensa, x86_64, microblazeel,
microblaze, i386. Consequently, qom-test runs twice for microblazeel
and x86_64.
Replace this complex and flawed machinery with a much simpler one: add
generic tests (currently just qom-test) to check-qtest-generic-y
instead of check-qtest-$(target)-y for every target, then run
$(check-qtest-generic-y) for every target.

This causes the region to outlive the object, because it attaches the

much worse for "instance_init" because it can cause dangling pointers

memory: allow destroying a non-empty MemoryRegion
This is legal; the MemoryRegion will simply unreference all the
existing subregions and possibly bring them down with it as well.
However, it requires a bit of care to avoid an infinite loop.
Finalizing a memory region cannot trigger an address space update,
but memory_region_del_subregion errs on the side of caution and
might trigger a spurious update: avoid that by resetting mr->enabled
first.

update-linux-headers: Rename SW_MAX to SW_MAX_
The next commit will compile hw/input/virtio-input.c and
hw/input/virtio-input-hid.c even when CONFIG_LINUX is off. These
files include both "include/standard-headers/linux/input.h" and
<windows.h> then. Doesn't work, because both define SW_MAX. We don't
actually use it. Patch input.h to define SW_MAX_ instead.

trace: remove malloc tracing
The malloc vtable is not supported anymore in glib, because it broke
when constructors called g_malloc. Remove tracing of g_malloc,
g_realloc and g_free calls.
Note that, for systemtap users, glib also provides tracepoints
glib.mem_alloc, glib.mem_free, glib.mem_realloc, glib.slice_alloc
and glib.slice_free.

Casting to a union type is a gcc (and clang) extension. Other compilers

can be removed easily. Smatch now no longer complains like before:

linux-user: Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T). Same Coccinelle semantic patch as in commit b45c03f.

.travis.yml: Run make check for all targets, not just some
ed173cb ".travis.yml: remove "make check" from main matrix" stopped running
make check for all the Travis build targets for various reasons. It
continued to run make check on one Travis build, which builds for a big
list of all (? nearly all) our supported softmmu targets.
Unfortunately, due to a spacing / quoting error it only actually builds for
the alpha, arm, aarch64 and cris targets. Specifically, the list of
targets is split over several lines. Even with YAML folding, this will
leave spaces in the list, meaning $TARGETS won't have the value we need.
I had a look at the YAML spec and I couldn't quickly see a way of splitting
the list so that it doesn't end up with spaces, so this patch fixes the
problem by putting the whole list on one huge line.

Generate an interrupt if the tx buffer is empty and the tx empty interrupt

Linux commit 55c3cb1358e ("serial: imx: remove unneeded imx_transmit_buffer()

starting to send data, causing transmit stalls until there is an interrupt

tcg: Adjust CODE_GEN_AVG_BLOCK_SIZE
At present, the "average" guestimate of TB size is way too small, leading
to many unused entries in the pre-allocated TB array. For a guest with 1GB
ram, we're currently allocating 256MB for the array.
Survey arm, alpha, aarch64, ppc, sparc, i686, x86_64 guests running on
x86_64 and ppc64 hosts and select a new average. The size of the array
drops to 81MB with no more flushing than before.

tcg: Check for overflow via highwater mark
We currently pre-compute an worst case code size for any TB, which
works out to be 122kB. Since the average TB size is near 1kB, this
wastes quite a lot of storage.
Instead, check for overflow in between generating code for each opcode.
The overhead of the check isn't measurable and wastage is minimized.

But it preserves existing logic, which will be good for bisection,

vfio: Allow hotplug of containers onto existing guest IOMMU mappings
At present the memory listener used by vfio to keep host IOMMU mappings
in sync with the guest memory image assumes that if a guest IOMMU
appears, then it has no existing mappings.
This may not be true if a VFIO device is hotplugged onto a guest bus
which didn't previously include a VFIO device, and which has existing
guest IOMMU mappings.
Therefore, use the memory_region_register_iommu_notifier_replay()
function in order to fix this case, replaying existing guest IOMMU
mappings, bringing the host IOMMU into sync with the guest IOMMU.

memory: Allow replay of IOMMU mapping notifications
When we have guest visible IOMMUs, we allow notifiers to be registered
which will be informed of all changes to IOMMU mappings. This is used by
vfio to keep the host IOMMU mappings in sync with guest IOMMU mappings.
However, unlike with a memory region listener, an iommu notifier won't be
told about any mappings which already exist in the (guest) IOMMU at the
time it is registered. This can cause problems if hotplugging a VFIO
device onto a guest bus which had existing guest IOMMU mappings, but didn't
previously have an VFIO devices (and hence no host IOMMU mappings).
This adds a memory_region_iommu_replay() function to handle this case. It
replays any existing mappings in an IOMMU memory region to a specified
notifier. Because the IOMMU memory region doesn't internally remember the
granularity of the guest IOMMU it has a small hack where the caller must
specify a granularity at which to replay mappings.
If there are finer mappings in the guest IOMMU these will be reported in
the iotlb structures passed to the notifier which it must handle (probably
causing it to flag an error). This isn't new - the VFIO iommu notifier
must already handle notifications about guest IOMMU mappings too short
for it to represent in the host IOMMU.

vfio: Check guest IOVA ranges against host IOMMU capabilities
The current vfio core code assumes that the host IOMMU is capable of
mapping any IOVA the guest wants to use to where we need. However, real
IOMMUs generally only support translating a certain range of IOVAs (the
"DMA window") not a full 64-bit address space.
The common x86 IOMMUs support a wide enough range that guests are very
unlikely to go beyond it in practice, however the IOMMU used on IBM Power
machines - in the default configuration - supports only a much more limited
IOVA range, usually 0..2GiB.
If the guest attempts to set up an IOVA range that the host IOMMU can't
map, qemu won't report an error until it actually attempts to map a bad
IOVA. If guest RAM is being mapped directly into the IOMMU (i.e. no guest
visible IOMMU) then this will show up very quickly. If there is a guest
visible IOMMU, however, the problem might not show up until much later when
the guest actually attempt to DMA with an IOVA the host can't handle.
This patch adds a test so that we will detect earlier if the guest is
attempting to use IOVA ranges that the host IOMMU won't be able to deal
with.
For now, we assume that "Type1" (x86) IOMMUs can support any IOVA, this is
incorrect, but no worse than what we have already. We can't do better for
now because the Type1 kernel interface doesn't tell us what IOVA range the
IOMMU actually supports.
For the Power "sPAPR TCE" IOMMU, however, we can retrieve the supported
IOVA range and validate guest IOVA ranges against it, and this patch does
so.

vfio: Generalize vfio_listener_region_add failure path
If a DMA mapping operation fails in vfio_listener_region_add() it
checks to see if we've already completed initial setup of the
container. If so it reports an error so the setup code can fail
gracefully, otherwise throws a hw_error().
There are other potential failure cases in vfio_listener_region_add()
which could benefit from the same logic, so move it to its own
fail: block. Later patches can use this to extend other failure cases
to fail as gracefully as possible under the circumstances.

vfio: Remove unneeded union from VFIOContainer
Currently the VFIOContainer iommu_data field contains a union with
different information for different host iommu types. However:
* It only actually contains information for the x86-like "Type1" iommu
* Because we have a common listener the Type1 fields are actually used
on all IOMMU types, including the SPAPR TCE type as well
In fact we now have a general structure for the listener which is unlikely
to ever need per-iommu-type information, so this patch removes the union.
In a similar way we can unify the setup of the vfio memory listener in
vfio_connect_container() that is currently split across a switch on iommu
type, but is effectively the same in both cases.
The iommu_data.release pointer was only needed as a cleanup function
which would handle potentially different data in the union. With the
union gone, it too can be removed.

hw/vfio/platform: irqfd setup sequence update
With current implementation, eventfd VFIO signaling is first set up and
then irqfd is setup, if supported and allowed.
This start sequence causes several issues with IRQ forwarding setup
which, if supported, is transparently attempted on irqfd setup:
IRQ forwarding setup is likely to fail if the IRQ is detected as under
injection into the guest (active at irqchip level or VFIO masked).
This currently always happens because the current sequence explicitly
VFIO-masks the IRQ before setting irqfd.
Even if that masking were removed, we couldn't prevent the case where
the IRQ is under injection into the guest.
So the simpler solution is to remove this 2-step startup and directly
attempt irqfd setup. This is what this patch does.
Also in case the eventfd setup fails, there is no reason to go farther:
let's abort.

Correctly re-init EFER state during INIT IPI
When doing a re-initialization of a CPU core, the default state is to _not_
have 64-bit long mode enabled. This means the LME (long mode enable) and LMA
(long mode active) bits in the EFER model-specific register should be cleared.
However, the EFER state is part of the CPU environment which is
preserved by do_cpu_init(), so if EFER.LME and EFER.LMA were set at the
time an INIT IPI was received, they will remain set after the init completes.
This is contrary to what the Intel architecture manual describes and what
happens on real hardware, and it leaves the CPU in a weird state that the
guest can't clear.
To fix this, the 'efer' member of the CPUX86State structure has been moved
to an area outside the region preserved by do_cpu_init(), so that it can
be properly re-initialized by x86_cpu_reset().

target-i386: add ABM to Haswell* and Broadwell* CPU models
ABM is only implemented as a single instruction set by AMD; all AMD
processors support both instructions or neither. Intel considers POPCNT
as part of SSE4.2, and LZCNT as part of BMI1, but Intel also uses AMD's
ABM flag to indicate support for both POPCNT and LZCNT. It has to be
added to Haswell and Broadwell because Haswell, by adding LZCNT, has
completed the ABM.
Tested with "qemu-kvm -cpu Haswell-noTSX,enforce" (and also with older
machine types) on an Haswell-EP machine.

vl: Add another sanity check to smp_parse() function
The code in smp_parse already checks the topology information for
sockets * cores * threads < cpus and bails out with an error in
that case. However, it is still possible to supply a bad configuration
the other way round, e.g. with:
qemu-system-xxx -smp 4,sockets=1,cores=4,threads=2
QEMU then still starts the guest, with topology configuration that
is rather incomprehensible and likely not what the user wanted.
So let's add another check to refuse such wrong configurations.

block/raw-posix: Open file descriptor O_RDWR to work around glibc posix_fallocate emulation issue.
https://bugzilla.redhat.com/show_bug.cgi?id=1265196
The following command fails on an NFS mountpoint:
$ qemu-img create -f qcow2 -o preallocation=falloc disk.img 262144
Formatting 'disk.img', fmt=qcow2 size=262144 encryption=off cluster_size=65536 preallocation='falloc' lazy_refcounts=off
qemu-img: disk.img: Could not preallocate data for the new file: Bad file descriptor
The reason turns out to be because NFS doesn't support the
posix_fallocate call. glibc emulates it instead. However glibc's
emulation involves using the pread(2) syscall. The pread syscall
fails with EBADF if the file descriptor is opened without the read
open-flag (ie. open (..., O_WRONLY)).
I contacted glibc upstream about this, and their response is here:
https://bugzilla.redhat.com/show_bug.cgi?id=1265196#c9
There are two possible fixes: Use Linux fallocate directly, or (this
fix) work around the problem in qemu by opening the file with O_RDWR
instead of O_WRONLY.

As of 934659c460d46c948cf348822fda1d38556ed9a4, $QEMU_IO is generally no
longer a program name, and therefore "sudo -n $QEMU_IO" will no longer

s390x: set missing parent for hotplug and quiesce events
Existing code missed to set a parent for the quiesce and hotplug event.
While this didn't matter in practise, new introspection APIs basically now
do an object_unref(object_new(T)), which loops forever.
When trying to remove the event facility bus, the code tries to
unparent all childs on the bus, so they are properly deleted and therefore removed.
As object_unparent() on these child devices doesn't work, as there is no parent,
we loop forever.
Let's fix this by adding the event facility as a parent. Also switch from
object_initialize to object_new, so the only valid reference is in fact the
parent property. This makes it more obvious when the device (state) is actually
gone (and how the reference counting works).

pc-bios/s390-ccw: avoid floating point operations
Some gcc versions (e.g. Fedora 22 gcc 5.1.1) seem to use floating
point registers for spilling and filling of general purpose registers.
As the BIOS does not activate the AFP register setting of CR0 this can
cause data exception program checks.
Disallow floating point in the BIOS as a simple solution.

During mirror, if the target device does not support zero init, a
mirror may result in a corrupted image for sync="full" mode.
This is due to how the initial dirty bitmap is set up prior to copying
data - we did not mark sectors as dirty that are unallocated. This
means those unallocated sectors are skipped over on the target, and for
a device without zero init, invalid data may reside in those holes.
If both of the following conditions are true, then we will explicitly
mark all sectors as dirty:
1.) sync = "full"
2.) bdrv_has_zero_init(target) == false
If the target does support zero init, but a target image is passed in
with data already present (i.e. an "existing" image), it is assumed the
data present in the existing image is valid data for those sectors.

Additionally, be more aggressive when deciding when to start throttling.
Previously we waited until four unproductive memory passes. Now we begin

arbitrary and only waiting for two passes allows us to complete the migration

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T). Same Coccinelle semantic patch as in commit b45c03f.

Currently, __target_cmsg_nxthdr compares a pointer derived from
target_cmsg against the msg_control field of target_msgh (through
subtraction). This failed for me when emulating i386 code under x86_64,
because pointers in the host address space and pointers in the guest
address space were not the same. This patch passes the initial value of
target_cmsg into __target_cmsg_nxthdr.
I found and fixed two more related bugs:
- __target_cmsg_nxthdr now returns the new cmsg pointer instead of the
old one.
- tgt_space (in host_to_target_cmsg) doesn't count "sizeof (struct
target_cmsghdr)" twice anymore.

linux-user: Add proper error messages for bad options
This patch adds better support for diagnosing option

the usage text and exited when a bad option or argument

for cases like '--help' (it wasn't clear that --help was

Removes the open dialog code that runs when no arguments are supplied with QEMU.

When the user puts QEMU in the background while holding

the user lets go of the key. When the user goes back to
QEMU, QEMU will think the key is still down causing
stuck key symptoms. This patch fixes this problem by
releasing all down keys when QEMU goes into the

sheepdog: refine discard support
This patch refines discard support of the sheepdog driver. The
existing discard mechanism was implemented on SD_OP_DISCARD_OBJ, which
was introduced before fine grained reference counting on newer
sheepdog. It doesn't care about relations of snapshots and clones and
discards objects unconditionally.
With this patch, the driver just updates an inode object for updating
reference. Removing the object is done in sheep process side.

sheepdog: use per AIOCB dirty indexes for non overlapping requests
In the commit 96b14ff85acf, requests for overlapping areas are
serialized. However, it cannot handle a case of non overlapping
requests. In such a case, min_dirty_data_idx and max_dirty_data_idx
can be overwritten by the requests and invalid inode update can
happen e.g. a case like create(1, 2) and create(3, 4) are issued in
parallel.
This patch lets SheepdogAIOCB have dirty data indexes instead of
BDRVSheepdogState for avoiding the above situation.
This patch also does trivial renaming for better description:

(get_ticks_per_sec() is 10^9)
But as PCI frequency is 33 MHz, we can also do:
y = x * 30; /* 33 MHz PCI period is 30 ns */
Which is much more simple.
This implies a 33.333333 MHz PCI frequency,

i6300esb: remove muldiv64()
Originally, timers were ticks based, and it made sense to
add ticks to current time to know when to trigger an alarm.
But since commit:
7447545 change all other clock references to use nanosecond resolution accessors
All timers use nanoseconds and we need to convert ticks to nanoseconds, by
doing something like:
y = muldiv64(x, get_ticks_per_sec(), PCI_FREQUENCY)
where x is the number of device ticks and y the number of system ticks.

Backup: don't do copy-on-read in before_write_notifier
We will copy data in before_write_notifier to do backup.
It is a nested I/O request, so we cannot do copy-on-read.
The steps to reproduce it:
1. -drive copy-on-read=on,... // qemu option
2. drive_backup -f disk0 /path_to_backup.img // monitor command

Arches that do any of:
1: provide this def exactly the same way as the new default
(alpha, x86_64)
2: check against ELF_MACHINE while defining ELF_ARCH == ELF_MACHINE
(arm, aarch64)
3: check against EM_FOO directly while defining ELF_ARCH == EM_FOO
(unicore32, sparc32, ppc32, mips, openrisc, sh4, cris, m86k)
have their elf_check_arch removed as the default will provide the
correct behaviour.

linux_user: elfload: Default ELF_MACHINE to ELF_ARCH
In most (but not all) cases, ELF_MACHINE and ELF_ARCH are safely the
same. Default ELF_MACHINE to ELF_ARCH. This makes defining ELF_MACHINE
optional for target-*/cpu.h when they are known to match.

Makefile: fix build when VPATH is outside GIT tree
Steve Ellcey / Leon Alrae reported that QEMU fails to build when
the VPATH directory is outside of the GIT tree, and the system
emulators & tools build is disabled. eg
cd ..
mkdir build
cd build
../qemu/configure --disable-system --disable-tools
make
(...)
make[1]: *** No rule to make target `../qom/object.o', needed by `qemu-aarch64'. Stop.
make: *** [subdir-aarch64-linux-user] Error 2
The problem is due to the fact that some sub directory deps
were listed against SOFTMMU_SUBDIR_RULES instead of SUBDIR_RULES,
so were only processed for system emulators, not user emalutors.

scsi-generic: let guests recognize readonly=on on passthrough devices
Passed-through SCSI devices can be opened with the readonly=on option.
When this happens, Linux filters away write commands so that the guest
cannot overwrite the contents of the device.
However, the guest does not know that the device is read-only, and
accepts writes. The writes only fail later when the page cache is
flushed.
This patch modifies scsi-generic to modify the MODE SENSE data and
set the read-only bit in the device-specific parameters, so that
the guest OS treats the disk as write protected.

oslib-win32: only provide localtime_r/gmtime_r if missing
The oslib-win32 file currently provides a localtime_r and
gmtime_r replacement unconditionally. Some versions of
Mingw-w64 would provide crude macros for localtime_r/gmtime_r
which QEMU takes care to disable. Latest versions of Mingw-w64
now provide actual functions for localtime_r/gmtime_r, but
with a twist that you have to include unistd.h or pthread.h
before including time.h. By luck some files in QEMU have
such an include order, resulting in compile errors:

This change adds a configure test to see if localtime_r
exits, and only enables the QEMU impl if missing. We also
re-arrange qemu-common.h try attempt to guarantee that all
source files get unistd.h before time.h and thus see the
localtime_r/gmtime_r defs.

gtk: avoid redefining _WIN32_WINNT macro

qemu-thread: add a fast path to the Win32 QemuEvent
QemuEvents are used heavily by call_rcu. We do not want them to be slow,
but the current implementation does a kernel call on every invocation
of qemu_event_* and won't cut it.
So, wrap a Win32 manual-reset event with a fast userspace path. The
states and transitions are the same as for the futex and mutex/condvar
implementations, but the slow path is different of course. The idea
is to reset the Win32 event lazily, as part of a test-reset-test-wait
sequence. Such a sequence is, indeed, how QemuEvents are used by
RCU and other subsystems!
The patch includes a formal model of the algorithm.

vhost-user: add multiple queue support
This patch is initially based a patch from Nikolay Nikolaev.
This patch adds vhost-user multiple queue support, by creating a nc
and vhost_net pair for each queue.
Qemu exits if find that the backend can't support the number of requested
queues (by providing queues=# option). The max number is queried by a
new message, VHOST_USER_GET_QUEUE_NUM, and is sent only when protocol
feature VHOST_USER_PROTOCOL_F_MQ is present first.
The max queue check is done at vhost-user initiation stage. We initiate
one queue first, which, in the meantime, also gets the max_queues the
backend supports.
In older version, it was reported that some messages are sent more times
than necessary. Here we came an agreement with Michael that we could
categorize vhost user messages to 2 types: non-vring specific messages,
which should be sent only once, and vring specific messages, which should
be sent per queue.
Here I introduced a helper function vhost_user_one_time_request(), which
lists following messages as non-vring specific messages:
VHOST_USER_SET_OWNER
VHOST_USER_RESET_DEVICE
VHOST_USER_SET_MEM_TABLE
VHOST_USER_GET_QUEUE_NUM
For above messages, we simply ignore them when they are not sent the first
time.

virtio: ring sizes vs. reset
We allow guests to change the size of the virtqueue rings by supplying
a number of buffers that is different from the number of buffers the
device was initialized with. Current code has some problems, however,
since reset does not reset the ringsizes to the default values (as this
is not saved anywhere).
Let's extend the core code to keep track of the default ringsizes and
migrate them once the guest changed them for any of the virtqueues
for a device.

virtio-net: unbreak self announcement and guest offloads after migration
After commit 019a3edbb25f1571e876f8af1ce4c55412939e5d ("virtio: make
features 64bit wide"). Device's guest_features was actually set after
vdc->load(). This breaks the assumption that device specific load()
function can check guest_features. For virtio-net, self announcement
and guest offloads won't work after migration.
Fixing this by defer them to virtio_net_load() where guest_features
were guaranteed to be set. Other virtio devices looks fine.

hw/arm/virt-acpi-build: Fix wrong size of flash in ACPI table
While virt machine creates two flash devices with total size 0x08000000,
the ACPI table generation code was wrongly using this total size as the
size of each flash device, so it would overlap other MMIO spaces.
Make each device entry in the table half the total; this brings the
ACPI table into line with the code which generates the device tree
and which creates the flash devices themselves.

This allows us to use different GIC types from v2. There are no kernels
which could advertise KVM_CAP_DEVICE_CTRL without the actual ability to
create GIC with it.
GIC version probe code moved to kvm_arm_vgic_probe() which will be used
later.

intc/gic: Extract some reusable vGIC code
Some functions previously used only by vGICv2 are useful also for vGICv3
implementation. Untie them from GICState and make accessible from within
other modules:
- kvm_arm_gic_set_irq()
- kvm_gic_supports_attr() - moved to common code and renamed to
kvm_device_check_attr()
- kvm_gic_access() - turned into GIC-independent kvm_device_access().
Data pointer changed to void * because some GICv3 registers are
64-bit wide
Some of these changes are not used right now, but they will be helpful for
implementing live migration.
Actually kvm_dist_get() and kvm_dist_put() could also be made reusable, but
they would require two extra parameters (s->dev_fd and s->num_cpu) as well as
lots of typecasts of 's' to DeviceState * and back to GICState *. This makes
the code very ugly so i decided to stop at this point. I tried also an
approach with making a base class for all possible GICs, but it would contain
only three variables (dev_fd, cpu_num and irq_num), and accessing them through
the rest of the code would be again tedious (either ugly casts or qemu-style
separate object pointer). So i disliked it too.

Currently it is mostly a placeholder, but in future it is supposed to hold

The interface of this class is fully compatible with GICv2 one. This is

vfio/pci: Add emulated PCI IDs
Specifying an emulated PCI vendor/device ID can be useful for testing
various quirk paths, even though the behavior and functionality of
the device with bogus IDs is fully unsupportable. We need to use a
uint32_t for the vendor/device IDs, even though the registers
themselves are only 16-bit in order to be able to determine whether
the value is valid and user set.
The same support is added for subsystem vendor/device ID, though these
have the possibility of being useful and supported for more than a
testing tool. An emulated platform might want to impose their own
subsystem IDs or at least hide the physical subsystem ID. Windows
guests will often reinstall drivers due to a change in subsystem IDs,
something that VM users may want to avoid. Of course careful
attention would be required to ensure that guest drivers do not rely
on the subsystem ID as a basis for device driver quirks.
All of these options are added using the standard experimental option
prefix and should not be considered stable.

vfio/pci: Config window quirks
Config windows make use of an address register and a data register.
In VGA cards, these are often used to provide real mode code in the
BIOS an easy way to access MMIO registers since the window often
resides in an I/O port register. When the MMIO register has a mirror
of PCI config space, we need to trap those accesses and redirect them
to emulated config space.
The previous version of this functionality made use of a single
MemoryRegion and single match address. This version uses separate
MemoryRegions for each of the address and data registers and allows
for multiple match addresses. This is useful for Nvidia cards which
have two ranges which index into PCI config space.
The previous implementation is left for the follow-on patch for a more
reviewable diff.

vfio/pci: Foundation for new quirk structure
VFIOQuirk hosts a single memory region and a fixed set of data fields
that try to handle all the quirk cases, but end up making those that
don't exactly match really confusing. This patch introduces a struct
intended to provide more flexibility and simpler code. VFIOQuirk is
stripped to its basics, an opaque data pointer for quirk specific
data and a pointer to an array of MemoryRegions with a counter. This
still allows us to have common teardown routines, but adds much
greater flexibility to support multiple memory regions and quirk
specific data structures that are easier to maintain. The existing
VFIOQuirk is transformed into VFIOLegacyQuirk, which further patches
will eliminate entirely.

vfio/pci: Cleanup ROM blacklist quirk
Create a vendor:device ID helper that we'll also use as we rework the
rest of the quirks. Re-reading the config entries, even if we get
more blacklist entries, is trivial overhead and only incurred during
device setup. There's no need to typedef the blacklist structure,
it's a static private data type used once. The elements get bumped
up to uint32_t to avoid future maintenance issues if PCI_ANY_ID gets
used for a blacklist entry (avoiding an actual hardware match). Our
test loop is also crying out to be simplified as a for loop.

ppc/spapr: Implement H_RANDOM hypercall in QEMU
The PAPR interface defines a hypercall to pass high-quality
hardware generated random numbers to guests. Recent kernels can
already provide this hypercall to the guest if the right hardware
random number generator is available. But in case the user wants
to use another source like EGD, or QEMU is running with an older
kernel, we should also have this call in QEMU, so that guests that
do not support virtio-rng yet can get good random numbers, too.
This patch now adds a new pseudo-device to QEMU that either
directly provides this hypercall to the guest or is able to
enable the in-kernel hypercall if available. The in-kernel
hypercall can be enabled with the use-kvm property, e.g.:
qemu-system-ppc64 -device spapr-rng,use-kvm=true
For handling the hypercall in QEMU instead, a "RngBackend" is
required since the hypercall should provide "good" random data
instead of pseudo-random (like from a "simple" library function
like rand() or g_random_int()). Since there are multiple RngBackends
available, the user must select an appropriate back-end via the
"rng" property of the device, e.g.:
qemu-system-ppc64 -object rng-random,filename=/dev/hwrng,id=gid0 \
-device spapr-rng,rng=gid0 ...
See http://wiki.qemu-project.org/Features-Done/VirtIORNG for
other example of specifying RngBackends.

ppc/spapr: Fix buffer overflow in spapr_populate_drconf_memory()
The buffer that is allocated in spapr_populate_drconf_memory()
is used for setting both, the "ibm,dynamic-memory" and the
"ibm,associativity-lookup-arrays" property. However, only the
size of the first one is taken into account when allocating the
memory. So if the length of the second property is larger than
the length of the first one, we run into a buffer overflow here!
Fix it by taking the length of the second property into account,
too.

spapr: Fix default NUMA node allocation for threads
At present, if guest numa nodes are requested, but the cpus in each node
are not specified, spapr just uses the default behaviour or assigning each
vcpu round-robin to nodes.
If smp_threads != 1, that will assign adjacent threads in a core to
different NUMA nodes. As well as being just weird, that's a configuration
that can't be represented in the device tree we give to the guest, which
means the guest and qemu end up with different ideas of the NUMA topology.
This patch implements mc->cpu_index_to_socket_id in the spapr code to
make sure vcpus get assigned to nodes only at the socket granularity.

spapr: Move memory hotplug to RTAS_LOG_V6_HP_ID_DRC_COUNT type
Till now memory hotplug used RTAS_LOG_V6_HP_ID_DRC_INDEX hotplug type
which meant that we generated one hotplug type of EPOW event for every
256MB (SPAPR_MEMORY_BLOCK_SIZE). This quickly overruns the kernel
rtas log buffer thus resulting in loss of memory hotplug events. Switch
to RTAS_LOG_V6_HP_ID_DRC_COUNT hotplug type for memory so that we
generate only one event per hotplug request.

spapr: Don't allow memory hotplug to memory less nodes
Currently PowerPC kernel doesn't allow hot-adding memory to memory-less
node, but instead will silently add the memory to the first node that has
some memory. This causes two unexpected behaviours for the user.
- Memory gets hotplugged to a different node than what the user specified.
- Since pc-dimm subsystem in QEMU still thinks that memory belongs to
memory-less node, a reboot will set things accordingly and the previously
hotplugged memory now ends in the right node. This appears as if some
memory moved from one node to another.
So until kernel starts supporting memory hotplug to memory-less
nodes, just prevent such attempts upfront in QEMU.

spapr: Use QEMU limit for maximum CPUs number
sPAPR uses hard coded limit of maximum 255 supported CPUs which is
exactly the same as QEMU-wide limit which is MAX_CPUMASK_BITS and also
defined as 255.
This makes use of a global CPU number limit for the "pseries" machine.
In order to anticipate future increase of the MAX_CPUMASK_BITS
(or to help debugging large systems), this also bumps the FDT_MAX_SIZE
limit from 256K to 1M assuming that 1 CPU core needs roughly 512 bytes
in the device tree so the new limit can cover up to 2048 CPU cores.

spapr: Don't use QOM [*] syntax for DR connectors.
The dynamic reconfiguration (hotplug) code for the pseries machine type
uses a "DR connector" QOM object for each resource it will be possible
to hotplug. Each of these is added to its owner using
object_property_add_child(owner, "dr-connector[*], ...);
That works ok, mostly, but it means that the property indices are
arbitrary, depending on the order in which the connectors are constructed.
That might line up to something useful, but it doesn't have to.
It will get worse once we add hotplug RAM support. That will add a DR
connector object for every 256MB of potential memory. So if maxmem=2T,
for example, there are 8192 objects under the same parent.
The QOM interfaces aren't really designed for this. In particular
object_property_add() with [*] has O(n^2) time complexity (in the number of
existing children): first it has a linear search through array indices to
find a free slot, each of which is attempted to a recursive call to
object_property_add() with a specific [N]. Those calls are O(n) because
there's a linear search through all properties to check for duplicates.
By using a meaningful index value, which we already know is unique we can
avoid the [*] special behaviour. That lets us reduce the total time for
creating the DR objects from O(n^3) to O(n^2).
O(n^2) is still kind of crappy, but it's enough to reduce the startup time
of qemu (with in-progress memory hotplug support) with maxmem=2T from ~20
minutes to ~4 seconds.

spapr_drc: use RTAS return codes for methods called by RTAS
Certain methods in sPAPRDRConnector objects are only ever called by
RTAS and in many cases are responsible for the logic that determines
the RTAS return codes.
Rather than having a level of indirection requiring RTAS code to
re-interpret return values from such methods to determine the
appropriate return code, just pass them through directly.
This requires changing method return types to uint32_t to match the
type of values currently passed to RTAS helpers.
In the case of read accesses like drc->entity_sense() where we weren't
previously reporting any errors, just the read value, we modify the
function to return RTAS return code, and pass the read value back via
reference.

spapr_drc: don't allow 'empty' DRCs to be unisolated or allocated
Logical resources start with allocation-state:UNUSABLE /
isolation-state:ISOLATED. During hotplug, guests will transition
them to allocation-state:USABLE, and then to
isolation-state:UNISOLATED.
For cases where we cannot transition to allocation-state:USABLE,
in this case due to no device/resource being association with
the logical DRC, we should return an error -3.
For physical DRCs, we default to allocation-state:USABLE and stay
there, so in this case we should report an error -3 when the guest
attempts to make the isolation-state:ISOLATED transition for a DRC
with no device associated.
These are as documented in PAPR 2.7, 13.5.3.4.
We also ensure allocation-state:USABLE when the guest attempts
transition to isolation-state:UNISOLATED to deal with misbehaving
guests attempting to bring online an unallocated logical resource.
This is as documented in PAPR 2.7, 13.7.
Currently we implement no such error logic. Fix this by handling
these error cases as PAPR defines.

spapr_pci: fix device tree props for MSI/MSI-X
PAPR requires ibm,req#msi and ibm,req#msi-x to be present in the
device node to define the number of msi/msi-x interrupts the device
supports, respectively.
Currently we have ibm,req#msi-x hardcoded to a non-sensical constant
that happens to be 2, and are missing ibm,req#msi entirely. The result
of that is that msi-x capable devices get limited to 2 msi-x
interrupts (which can impact performance), and msi-only devices likely
wouldn't work at all. Additionally, if devices expect a minimum that
exceeds 2, the guest driver may fail to load entirely.
SLOF still owns the generation of these properties at boot-time
(although other device properties have since been offloaded to QEMU),
but for hotplugged devices we rely on the values generated by QEMU
and thus hit the limitations above.
Fix this by generating these properties in QEMU as expected by guests.
In the future it may make sense to modify SLOF to pass through these
values directly as we do with other props since we're duplicating SLOF
code.

pseries: Fix incorrect calculation of threads per socket for chip-id
The device tree presented to pseries machine type guests includes an
ibm,chip-id property which gives essentially the socket number of each
vcpu core (individual vcpu threads don't get a node in the device
tree).
To calculate this, it uses a vcpus_per_socket variable computed as
(smp_cpus / #sockets). This is correct for the usual case where
smp_cpus == smp_threads * smp_cores * #sockets.
However, you can start QEMU with the number of cores and threads
mismatching the total number of vcpus (whether that _should_ be
permitted is a topic for another day). It's a bit hard to say what
the "real" number of vcpus per socket here is, but for most purposes
(smp_threads * smp_cores) will more meaningfully match how QEMU
behaves with respect to socket boundaries.

pseries: define coldplugged devices as "configured"
When a device is hotplugged, attach() sets "configured" to
false, waiting an action from the OS to configure it and then
to call ibm,configure-connector. On ibm,configure-connector,
the hypervisor sets "configured" to true.
In case of coldplugged device, attach() sets "configured" to
false, but firmware and OS never call the ibm,configure-connector
in this case, so it remains set to false.
It could be harmless, but when we unplug a device, hypervisor
waits the device becomes configured because for it, a not configured
device is a device being configured, so it waits the end of configuration
to unplug it... and it never happens, so it is never unplugged.
This patch set by default coldplugged device to "configured=true",
hotplugged device to "configured=false".

ppc/spapr: Use qemu_log_mask() for hcall_dprintf()
To see the output of the hcall_dprintf statements, you currently have
to enable the DEBUG_SPAPR_HCALLS macro in include/hw/ppc/spapr.h.
This is ugly because a) not every user who wants to debug guest
problems can or wants to recompile QEMU to be able to see such issues,
and b) since this macro is disabled by default, the code in the
hcall_dprintf() brackets tends to bitrot until somebody temporarily
enables that macro again.
Since the hcall_dprintf statements except one indicate guest
problems, let's always use qemu_log_mask(LOG_GUEST_ERROR, ...) for
this macro instead. One spot indicated an unimplemented host feature,
so this is changed into qemu_log_mask(LOG_UNIMP, ...) instead. Now
it's possible to see all those messages by simply adding the CLI
parameter "-d guest_errors,unimp", without the need to re-compile
the binary.

spapr_drc: Fix potential undefined behaviour
The DRC_INDEX_ID_MASK macro does a left shift on ~0, which is a signed

particular this causes warnings from the clang sanitizer.
This fixes it by calculating the same mask without using ~0 (I think the
new method is a more common idiom for generating masks anyway). For good
measure I also use 1ULL to force the expression's type to unsigned long
long, which should be good for assigning to anything we're going to want
to.

monitor: allow device_del to accept QOM paths
Currently device_del requires that the client provide the
device short ID. device_add allows devices to be created
without giving an ID, at which point there is no way to
delete them with device_del. The QOM object path, however,
provides an alternative way to identify the devices.
Allowing device_del to accept an object path ensures all
devices are deletable regardless of whether they have an
ID.

qapi: New QMP command query-qmp-schema for QMP introspection
qapi/introspect.json defines the introspection schema. It's designed
for QMP introspection, but should do for similar uses, such as QGA.
The introspection schema does not reflect all the rules and
restrictions that apply to QAPI schemata. A valid QAPI schema has an
introspection value conforming to the introspection schema, but the
converse is not true.
Introspection lowers away a number of schema details, and makes
implicit things explicit:
* The built-in types are declared with their JSON type.
All integer types are mapped to 'int', because how many bits we use
internally is an implementation detail. It could be pressed into
external interface service as very approximate range information,
but that's a bad idea. If we need range information, we better do
it properly.
* Implicit type definitions are made explicit, and given
auto-generated names:
- Array types, named by appending "List" to the name of their
element type, like in generated C.
- The enumeration types implicitly defined by simple union types,
named by appending "Kind" to the name of their simple union type,
like in generated C.
- Types that don't occur in generated C. Their names start with ':'
so they don't clash with the user's names.
* All type references are by name.
* The struct and union types are generalized into an object type.
* Base types are flattened.
* Commands take a single argument and return a single result.
Dictionary argument or list result is an implicit type definition.
The empty object type is used when a command takes no arguments or
produces no results.
The argument is always of object type, but the introspection schema
doesn't reflect that.
The 'gen': false directive is omitted as implementation detail.
The 'success-response' directive is omitted as well for now, even
though it's not an implementation detail, because it's not used by
QMP.
* Events carry a single data value.
Implicit type definition and empty object type use, just like for
commands.
The value is of object type, but the introspection schema doesn't
reflect that.
* Types not used by commands or events are omitted.
Indirect use counts as use.
* Optional members have a default, which can only be null right now
Instead of a mandatory "optional" flag, we have an optional default.
No default means mandatory, default null means optional without
default value. Non-null is available for optional with default
(possible future extension).
* Clients should *not* look up types by name, because type names are
not ABI. Look up the command or event you're interested in, then
follow the references.
TODO Should we hide the type names to eliminate the temptation?
New generator scripts/qapi-introspect.py computes an introspection
value for its input, and generates a C variable holding it.
It can generate awfully long lines. Marked TODO.
A new test-qmp-input-visitor test case feeds its result for both
tests/qapi-schema/qapi-schema-test.json and qapi-schema.json to a
QmpInputVisitor to verify it actually conforms to the schema.
New QMP command query-qmp-schema takes its return value from that
variable. Its reply is some 85KiBytes for me right now.
If this turns out to be too much, we have a couple of options:
* We can use shorter names in the JSON. Not the QMP style.
* Optionally return the sub-schema for commands and events given as
arguments.
Right now qmp_query_schema() sends the string literal computed by
qmp-introspect.py. To compute sub-schema at run time, we'd have to
duplicate parts of qapi-introspect.py in C. Unattractive.
* Let clients cache the output of query-qmp-schema.
It changes only on QEMU upgrades, i.e. rarely. Provide a command
query-qmp-schema-hash. Clients can have a cache indexed by hash,
and re-query the schema only when they don't have it cached. Even
simpler: put the hash in the QMP greeting.

qapi: Make output visitor return qnull() instead of NULL
Before commit 1d10b44, it crashed. Since then, it returns NULL, with
a FIXME comment. The FIXME is valid: code that assumes QObject *
can't be null exists. I'm not aware of a way to feed this problematic
return value to code that actually chokes on null in the current code,
but the next few commits will create one, failing "make check".
Commit 481b002 solved a very similar problem by introducing a special
null QObject. Using this special null QObject is clearly the right
way to resolve this FIXME, so do that, and update the test
accordingly.
However, the patch isn't quite right: it messes up the reference
counting. After about SIZE_MAX visits, the reference counter
overflows, failing the assertion in qnull_destroy_obj(). Because
that's many orders of magnitude more visits of nulls than we expect,
we take this patch despite its flaws, to get the QMP introspection
stuff in without further delay. We'll want to fix it for real before
the release.

qapi-visit: Convert to QAPISchemaVisitor, fixing bugs

Patch's effect on visit_type_UserDefFlatUnion():
static void visit_type_UserDefFlatUnion_fields(Visitor *m, UserDefFlatUnion **obj, Error **errp)
{
Error *err = NULL;
+ visit_type_int(m, &(*obj)->integer, "integer", &err);

Test cases updated for the bug fix.
Fixes alternates to generate a visitor for their implicit enumeration
type. None of them are currently used, obviously. Example:
block-core.json's BlockdevRef now generates
visit_type_BlockdevRefKind().
Code is generated in a different order now, and therefore has got a
few new forward declarations. Doesn't matter.

qapi-types: Convert to QAPISchemaVisitor, fixing flat unions
Fixes flat unions to get the base's base members. Test case is from
commit 2fc0043, in qapi-schema-test.json:
{ 'union': 'UserDefFlatUnion',
'base': 'UserDefUnionBase',
'discriminator': 'enum1',
'data': { 'value1' : 'UserDefA',
'value2' : 'UserDefB',
'value3' : 'UserDefB' } }
{ 'struct': 'UserDefUnionBase',
'base': 'UserDefZero',
'data': { 'string': 'str', 'enum1': 'EnumOne' } }
{ 'struct': 'UserDefZero',
'data': { 'integer': 'int' } }
Patch's effect on UserDefFlatUnion:
struct UserDefFlatUnion {
/* Members inherited from UserDefUnionBase: */
+ int64_t integer;
char *string;
EnumOne enum1;
/* Own members: */
union { /* union tag is @enum1 */
void *data;
UserDefA *value1;
UserDefB *value2;
UserDefB *value3;
};
};
Flat union visitors remain broken. They'll be fixed next.
Code is generated in a different order now, but that doesn't matter.
The two guards QAPI_TYPES_BUILTIN_STRUCT_DECL and
QAPI_TYPES_BUILTIN_CLEANUP_DECL are replaced by just
QAPI_TYPES_BUILTIN.
Two ugly special cases for simple unions now stand out like sore
thumbs:
1. The type tag is named 'type' everywhere, except in generated C,
where it's 'kind'.
2. QAPISchema lowers simple unions to semantically equivalent flat
unions. However, the C generated for a simple unions differs from
the C generated for its equivalent flat union, and we therefore
need special code to preserve that pointless difference for now.
Mark both TODO.

qapi: New QAPISchema intermediate reperesentation
The QAPI code generators work with a syntax tree (nested dictionaries)
plus a few symbol tables (also dictionaries) on the side.
They have clearly outgrown these simple data structures. There's lots
of rummaging around in dictionaries, and information is recomputed on
the fly. For the work I'm going to do, I want more clearly defined
and more convenient interfaces.
Going forward, I also want less coupling between the back-ends and the
syntax tree, to make messing with the syntax easier.
Create a bunch of classes to represent QAPI schemata.
Have the QAPISchema initializer call the parser, then walk the syntax
tree to create the new internal representation, and finally perform
semantic analysis.
Shortcut: the semantic analysis still relies on existing check_exprs()
to do the actual semantic checking. All this code needs to move into
the classes. Mark as TODO.
Simple unions are lowered to flat unions. Flat unions and structs are
represented as a more general object type.
Catching name collisions in generated code would be nice. Mark as
TODO.
We generate array types eagerly, even though most of them aren't used.
Mark as TODO.
Nothing uses the new intermediate representation just yet, thus no
change to generated files.

The code to flush the DBDMA channel was effectively duplicated in

Newer PPC Linux kernels would timeout waiting for the FLUSH bit to clear again

Revert use of DEFINE_MACHINE() for registrations of multiple machines
The script used for converting from QEMUMachine had used one
DEFINE_MACHINE() per machine registered. In cases where multiple

tcg/mips: Fix clobbering of qemu_ld inputs
The MIPS TCG backend implements qemu_ld with 64-bit targets using the v0
register (base) as a temporary to load the upper half of the QEMU TLB
comparator (see line 5 below), however this happens before the input
address is used (line 8 to mask off the low bits for the TLB
comparison, and line 12 to add the host-guest offset). If the input
address (addrl) also happens to have been placed in v0 (as in the second
column below), it gets clobbered before it is used.
addrl in t2 addrl in v0

7 lw a0,9160(a0) lw a0,9160(a0) set addend (a0)

12 addu v0,a0,t2 addu v0,a0,v0 use addrl, addend
13 lw t0,0(v0) lw t0,0(v0)
Fix by using TCG_TMP0 (at) as the temporary instead of v0 (base),
pushing the load on line 5 forward into the delay slot of the low
comparison (line 10). The early load of the addend on line 7 also needs
pushing even further for 64-bit targets, or it will clobber a0 before
we're done with it. The output for 32-bit targets is unaffected.

qdev: Do not use slow [*] expansion for GPIO creation
Expansion of [*] suffix is very slow because index expansion is done using
trial and error strategy, starting every time from zero and retrying with
the next index until insertion succeeds. With large number of already added
properties this process takes huge amount of time (O(n^2) complexity).
Some architectures (like ARM) use very large amount of IRQ pins in interrupt
controller models. This flaw makes machine startup extremely slow
(~20 seconds for ARM64 with 32 CPUs). This patch decreases this time down to
~10 seconds.
Also in qdev_init_gpio_out_named() memset() is now called only once for the
whole array instead of per-cell cleaning

When a function returns a null pointer on error and only on error, you

instead of the more cumbersome
Error *err = NULL;
if (!foo(foos, &err)) {

}
A StringProperty's getter, however, may return null on success! We
then fail to call visit_type_str().

The initial register device-to-host FIS no longer needs to specially

fields explicitly with the signatures we want at port reset time.
(1) Signatures are decomposed into their four component registers and
set upon (AHCI) port reset.
(2) the signature cache register is no longer set manually per-each
device type, but instead just once during ahci_init_d2h.

atapi: abort transfers with 0 byte limits
We're supposed to abort on transfers like this, unless we fill
Word 125 of our IDENTIFY data with a default transfer size, which
we don't currently do.
This is an ATA error, not a SCSI/ATAPI one.
See ATA8-ACS3 sections 7.17.6.49 or 7.21.5.
If we don't do this, QEMU will loop forever trying to transfer
zero bytes, which isn't particularly useful.

- ATA4 Section 6.5 ("PACKET Command feature set")
- ATA8/ACS Section 4.3 ("The PACKET feature set")
- ACS3 Section 4.3 ("The PACKET feature set")
ACS3 has a historical command validity table in Table B.4
("Historical Command Assignments") that can be referenced to find when
a command was introduced, deprecated, obsoleted, etc.
The only reference for ATAPI command validity is by checking that
version's PACKET feature set section.
ATAPI was introduced by T13 into ATA4, all commands retired prior to ATA4
therefore are assumed to have never been ATAPI commands.
Mandatory commands, as listed in ATA8-ACS3, are:
- DEVICE RESET
- EXECUTE DEVICE DIAGNOSTIC
- IDENTIFY DEVICE
- IDENTIFY PACKET DEVICE
- NOP
- PACKET
- READ SECTOR(S)
- SET FEATURES
Optional commands as listed in ATA8-ACS3, are:
- FLUSH CACHE
- READ LOG DMA EXT
- READ LOG EXT
- WRITE LOG DMA EXT
- WRITE LOG EXT
All other commands are illegal to send to an ATAPI device and should
be rejected by the device.
CD_OK removal justifications:
0x06 WIN_DSM Defined in ACS2. Not valid for ATAPI.
0x21 WIN_READ_ONCE Retired in ATA5. Not ATAPI in ATA4.
0x94 WIN_STANDBYNOW2 Retired in ATA4. Did not coexist with ATAPI.
0x95 WIN_IDLEIMMEDIATE2 Retired in ATA4. Did not coexist with ATAPI.
0x96 WIN_STANDBY2 Retired in ATA4. Did not coexist with ATAPI.
0x97 WIN_SETIDLE2 Retired in ATA4. Did not coexist with ATAPI.
0x98 WIN_CHECKPOWERMODE2 Retired in ATA4. Did not coexist with ATAPI.
0x99 WIN_SLEEPNOW2 Retired in ATA4. Did not coexist with ATAPI.
0xE0 WIN_STANDBYNOW1 Not part of ATAPI in ATA4, ACS or ACS3.
0xE1 WIN_IDLEIMMDIATE Not part of ATAPI in ATA4, ACS or ACS3.
0xE2 WIN_STANDBY Not part of ATAPI in ATA4, ACS or ACS3.
0xE3 WIN_SETIDLE1 Not part of ATAPI in ATA4, ACS or ACS3.
0xE4 WIN_CHECKPOWERMODE1 Not part of ATAPI in ATA4, ACS or ACS3.
0xE5 WIN_SLEEPNOW1 Not part of ATAPI in ATA4, ACS or ACS3.
0xF8 WIN_READ_NATIVE_MAX Obsoleted in ACS3. Not ATAPI in ATA4 or ACS.
This patch fixes a divide by zero fault that can be caused by sending
the WIN_READ_NATIVE_MAX command to an ATAPI drive, which causes it to
attempt to use zeroed CHS values to perform sector arithmetic.

memory: Fix bad error handling in memory_region_init_ram_ptr()
Commit ef701d7 screwed up handling of out-of-memory conditions.
Before the commit, we report the error and exit(1), in one place. The
commit lifts the error handling up the call chain some, to three
places. Fine. Except it uses &error_abort in these places, changing
the behavior from exit(1) to abort(), and thus undoing the work of
commit 3922825 "exec: Don't abort when we can't allocate guest
memory".
The previous two commits fixed one of the three places, another one
was fixed in commit 33e0eb5. This commit fixes the third one.

Fix bad error handling after memory_region_init_ram()
Symptom:
$ qemu-system-x86_64 -m 10000000
Unexpected error in ram_block_add() at /work/armbru/qemu/exec.c:1456:
upstream-qemu: cannot set up guest memory 'pc.ram': Cannot allocate memory
Aborted (core dumped)
Root cause: commit ef701d7 screwed up handling of out-of-memory
conditions. Before the commit, we report the error and exit(1), in
one place, ram_block_add(). The commit lifts the error handling up
the call chain some, to three places. Fine. Except it uses
&error_abort in these places, changing the behavior from exit(1) to
abort(), and thus undoing the work of commit 3922825 "exec: Don't
abort when we can't allocate guest memory".
The three places are:
* memory_region_init_ram()
Commit 4994653 (right after commit ef701d7) lifted the error
handling further, through memory_region_init_ram(), multiplying the
incorrect use of &error_abort. Later on, imitation of existing
(bad) code may have created more.
* memory_region_init_ram_ptr()
The &error_abort is still there.
* memory_region_init_rom_device()
Doesn't need fixing, because commit 33e0eb5 (soon after commit
ef701d7) lifted the error handling further, and in the process
changed it from &error_abort to passing it up the call chain.
Correct, because the callers are realize() methods.
Fix the error handling after memory_region_init_ram() with a
Coccinelle semantic patch:
@r@
expression mr, owner, name, size, err;
position p;
@@
memory_region_init_ram(mr, owner, name, size,
(
- &error_abort
+ &error_fatal
|
err@p
)
);
@script:python@
p << r.p;
@@
print "%s:%s:%s" % (p[0].file, p[0].line, p[0].column)
When the last argument is &error_abort, it gets replaced by
&error_fatal. This is the fix.
If the last argument is anything else, its position is reported. This
lets us check the fix is complete. Four positions get reported:
* ram_backend_memory_alloc()
Error is passed up the call chain, ultimately through
user_creatable_complete(). As far as I can tell, it's callers all
handle the error sanely.
* fsl_imx25_realize(), fsl_imx31_realize(), dp8393x_realize()
DeviceClass.realize() methods, errors handled sanely further up the
call chain.
We're good. Test case again behaves:
$ qemu-system-x86_64 -m 10000000
qemu-system-x86_64: cannot set up guest memory 'pc.ram': Cannot allocate memory
[Exit 1 ]
The next commits will repair the rest of commit ef701d7's damage.

hmp: Allow for error message hints on HMP
Commits 7216ae3d and d2828429 disabled some error message hints,
all because a change to use modern error reporting meant that the
hint would be output prior to the actual error. Fix this by making
hints a first-class member of Error.
For example, we are now back to the pleasant:
$ qemu-system-x86_64 --nodefaults -S --vnc :0 --chardev null,id=,
qemu-system-x86_64: --chardev null,id=,: Parameter 'id' expects an identifier
Identifiers consist of letters, digits, '-', '.', '_', starting with a letter.

error: only prepend timestamp on stderr
The -msg timestamp=on option prepends a timestamp to error messages.
This is useful on stderr where it allows users to identify when an error
was raised.
Timestamps do not make sense on the monitor since error_report() is
called in response to a synchronous monitor command and the user already
knows "when" the command was issued. Additionally, the rest of the
monitor conversation lacks timestamps so the error timestamp cannot be
correlated with other activity.
Only prepend timestamps on stderr. This fixes libvirt's 'drive_del'
processing, which did not expect a timestamp. Other QEMU monitor
clients are probably equally confused by timestamps on monitor error
messages.

target-mips: improve exception handling
This patch improves exception handling in MIPS.
Instructions generate several types of exceptions.
When exception is generated, it breaks the execution of the current
translation block. Implementation of the exceptions handling does not
correctly restore icount for the instruction which caused the exception.
In most cases icount will be decreased by the value equal to the size of
TB. This patch passes pointer to the translation block internals to the
exception handler. It allows correct restoring of the icount value.

target-mips: fix corner case in TLBWR causing QEMU to hang
cpu_mips_get_random() function is used to generate a random index from
CP0.Wired to TLBSize-1 range. Current implementation avoids generating
the same as before value, hence the while loop. If the guest sets
CP0.Wired to TLBSize-1 (which actually does not sound to be very
practical) QEMU will get stuck in the loop infinitely as we always
generate the same index.

pic32: use LCG algorithm for generated random index of TLBWR instruction
The LFSR algorithm, used for generating random TLB indexes for TLBWR
instruction, was inclined to produce a degenerate sequence in some cases.
For example, for 16-entry TLB size and Wired=1, it gives: 15, 6, 7, 2,
7, 2, 7, 2, 7, 2, 7, 2, 7, 2, 7, 2, 7, 2, 7, 2, 7, 2, 7, 2, 7, 2, 7, 2...
When replaced with LCG algorithm from ISO/IEC 9899 standard, the sequence
looks much better, with about the same computational effort needed.

MIPS_DEBUG is a define used to dump the instruction disassembling. It

clutters translate.c.

ide: unify io_buffer_offset increments
IDEState's io_buffer_offset was originally added to keep track of offsets
in AHCI rather exclusively, but it was added to IDEState instead of an
AHCI-specific structure.
AHCI fakes all PIO transfers using DMA and a scatter-gather list. When
the core or atapi layers invoke HBA-specific mechanisms for transfers,
they do not always know that it is being backed by DMA or a sglist, so
this offset is not always updated by the HBA code everywhere.
If we modify it in dma_buf_commit, however, any HBA that needs to use
this offset to manage operating on only part of a sglist will have
access to it.
This will fix ATAPI PIO transfers performed through the AHCI HBA,
which were previously not modifying this value appropriately.
This will fix ATAPI PIO transfers larger than one sector.

target-cris: update CPU state save/load to use VMStateDescription
Update the CRIS CPU state save/load to use a VMStateDescription struct
rather than cpu_save/cpu_load functions.
Have to define TLBSet struct.

net: smc91c111: flush packets on RCR register changes
The SOFT_RST or RXEN in the control register can be used as a condition
to unblock the net layer via can_receive(). So check for possible
flushes on RCR changes. This will drop all pending packets on soft
reset or disable which is the functional intent of the can_receive()
logic.

net: smc91c111: gate can_receive() on rx FIFO having a slot
Return false from can_receive() when the FIFO doesn't have a free RX
slot. This fixes a bug in the current code where the allocated buffer
is freed before the fifo pop, triggering a premature flush of queued RX
packets. It also will handle a corner case, where the guest manually
frees the allocated buffer before popping the rx FIFO (hence it is not
enough to just delay the flush_queued_packets()).

qemu-char: Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T). Same Coccinelle semantic patch as in commit b45c03f.

update-linux-headers: copy standard-headers files one by one
cp_virtio is called for both the asm-s390/ and linux/ directories,
so it looks for pci_regs.h and input.h files in asm-s390/ too. This
makes little sense. In the next patch we will have the opposite
problem; we want to add asm-x86/hyperv.h, and there's also a
linux/hyperv.h file with unwanted dependencies on additional Linux
uapi headers. We do not want to copy linux/hyperv.h.
The solution is to make cp_virtio (now renamed to cp_portable) copy
one file only, instead of using the "find" command, and call it multiple
times. The new function is really just a reindentation of the old one.

pci: remove Link Training error from AER error list
The spec says:
Undefined – The value read from this bit is
undefined. In previous versions of this
specification, this bit was used to indicate a Link
Training Error. System software must ignore the
value read from this bit. System software is
permitted to write any value to this bit.
Do not allow injecting it.

ui: convert VNC server to use QCryptoTLSSession
Switch VNC server over to using the QCryptoTLSSession object
for the TLS session. This removes the direct use of gnutls
from the VNC server code. It also removes most knowledge
about TLS certificate handling from the VNC server code.
This has the nice effect that all the CONFIG_VNC_TLS
conditionals go away and the user gets an actual error
message when requesting TLS instead of it being silently
ignored.
With this change, the existing configuration options for
enabling TLS with -vnc are deprecated.
Old syntax for anon-DH credentials:
-vnc hostname:0,tls
New syntax:
-object tls-creds-anon,id=tls0,endpoint=server \
-vnc hostname:0,tls-creds=tls0
Old syntax for x509 credentials, no client certs:
-vnc hostname:0,tls,x509=/path/to/certs
New syntax:
-object tls-creds-x509,id=tls0,dir=/path/to/certs,endpoint=server,verify-peer=no \
-vnc hostname:0,tls-creds=tls0
Old syntax for x509 credentials, requiring client certs:
-vnc hostname:0,tls,x509verify=/path/to/certs
New syntax:
-object tls-creds-x509,id=tls0,dir=/path/to/certs,endpoint=server,verify-peer=yes \
-vnc hostname:0,tls-creds=tls0
This aligns VNC with the way TLS credentials are to be
configured in the future for chardev, nbd and migration
backends. It also has the benefit that the same TLS
credentials can be shared across multiple VNC server
instances, if desired.
If someone uses the deprecated syntax, it will internally
result in the creation of a 'tls-creds' object with an ID
based on the VNC server ID. This allows backwards compat
with the CLI syntax, while still deleting all the original
TLS code from the VNC server.

crypto: introduce new module for handling TLS sessions
Introduce a QCryptoTLSSession object that will encapsulate
all the code for setting up and using a client/sever TLS
session. This isolates the code which depends on the gnutls
library, avoiding #ifdefs in the rest of the codebase, as
well as facilitating any possible future port to other TLS
libraries, if desired. It makes use of the previously
defined QCryptoTLSCreds object to access credentials to
use with the session. It also includes further unit tests
to validate the correctness of the TLS session handshake
and certificate validation. This is functionally equivalent
to the current TLS session handling code embedded in the
VNC server, and will obsolete it.

crypto: add sanity checking of TLS x509 credentials
If the administrator incorrectly sets up their x509 certificates,
the errors seen at runtime during connection attempts are very
obscure and difficult to diagnose. This has been a particular
problem for people using openssl to generate their certificates
instead of the gnutls certtool, because the openssl tools don't
turn on the various x509 extensions that gnutls expects to be
present by default.
This change thus adds support in the TLS credentials object to
sanity check the certificates when QEMU first loads them. This
gives the administrator immediate feedback for the majority of
common configuration mistakes, reducing the pain involved in
setting up TLS. The code is derived from equivalent code that
has been part of libvirt's TLS support and has been seen to be
valuable in assisting admins.
It is possible to disable the sanity checking, however, via
the new 'sanity-check' property on the tls-creds object type,
with a value of 'no'.
Unit tests are included in this change to verify the correctness
of the sanity checking code in all the key scenarios it is
intended to cope with. As part of the test suite, the pkix_asn1_tab.c
from gnutls is imported. This file is intentionally copied from the
(long since obsolete) gnutls 1.6.3 source tree, since that version
was still under GPLv2+, rather than the GPLv3+ of gnutls >= 2.0.

crypto: introduce new base module for TLS credentials
Introduce a QCryptoTLSCreds class to act as the base class for
storing TLS credentials. This will be later subclassed to provide
handling of anonymous and x509 credential types. The subclasses
will be user creatable objects, so instances can be created &
deleted via 'object-add' and 'object-del' QMP commands respectively,
or via the -object command line arg.
If the credentials cannot be initialized an error will be reported
as a QMP reply, or on stderr respectively.
The idea is to make it possible to represent and manage TLS
credentials independently of the network service that is using
them. This will enable multiple services to use the same set of
credentials and minimize code duplication. A later patch will
convert the current VNC server TLS code over to use this object.
The representation of credentials will be functionally equivalent
to that currently implemented in the VNC server with one exception.
The new code has the ability to (optionally) load a pre-generated
set of diffie-hellman parameters, if the file dh-params.pem exists,
whereas the current VNC server will always generate them on startup.
This is beneficial for admins who wish to avoid the (small) time
sink of generating DH parameters at startup and/or avoid depleting
entropy.

crypto: move crypto objects out of libqemuutil.la
Future patches will be adding more crypto related APIs which
rely on QOM infrastructure. This creates a problem, because
QOM relies on library constructors to register objects. When
you have a file in a static .a library though which is only
referenced by a constructor the linker is dumb and will drop
that file when linking to the final executable :-( The only
workaround for this is to link the .a library to the executable
using the -Wl,--whole-archive flag, but this creates its own
set of problems because QEMU is relying on lazy linking for
libqemuutil.a. Using --whole-archive majorly increases the
size of final executables as they now contain a bunch of
object code they don't actually use.
The least bad option is to thus not include the crypto objects
in libqemuutil.la, and instead define a crypto-obj-y variable
that is referenced directly by all the executables that need
this code (tools + softmmu, but not qemu-ga). We avoid pulling
entire of crypto-obj-y into the userspace emulators as that
would force them to link to gnutls too, which is not required.

gtk: use setlocale() for LC_MESSAGES only
The QEMU code is not internationalized and assumes that it runs under
the C locale, but if we use the GTK+ UI we'll end up importing the
locale settings from the environment. This can break things, such as
the JSON generator and iotest 120 in locales that use a decimal comma.
We do however have translations for a few simple strings for the GTK+
menu items, so in order to run QEMU using the C locale, and yet have a
translated UI let's use setlocale() for LC_MESSAGES only.

qapi: allow override of default enum prefix naming
The camel_to_upper() method applies some heuristics to turn
a mixed case type name into an all-uppercase name. This is
used for example, to generate enum constant name prefixes.
The heuristics don't also generate a satisfactory name
though. eg
{ 'enum': 'QCryptoTLSCredsEndpoint',
'data': ['client', 'server']}
Results in Q_CRYPTOTLS_CREDS_ENDPOINT_CLIENT. This has
an undesirable _ after the initial Q and is missing an
_ between the CRYPTO & TLS strings.
Rather than try to add more and more heuristics to try
to cope with this, simply allow the QAPI schema to
specify the desired enum constant prefix explicitly.
eg
{ 'enum': 'QCryptoTLSCredsEndpoint',
'prefix': 'QCRYPTO_TLS_CREDS_ENDPOINT',
'data': ['client', 'server']}
Now gives the QCRYPTO_TLS_CREDS_ENDPOINT_CLIENT name.

qcow2: Make qcow2_alloc_bytes() more explicit
In case of -EAGAIN returned by update_refcount(), we should discard the
cluster offset we were trying to allocate and request a new one, because
in theory that old offset might now be taken by a refcount block.
In practice, this was not the case due to update_refcount() generally
returning strictly monotonic increasing cluster offsets. However, this
behavior is not set in stone, and it is also not obvious when looking at
qcow2_alloc_bytes() alone, so we should not rely on it.

vmdk: Fix next_cluster_sector for compressed write
When the VMDK is streamOptimized (or compressed), the
next_cluster_sector must not be incremented by a fixed number of
sectors. Instead of this, it must be rounded up to the next consecutive
sector. Fixing this results in much smaller compressed images.

qcow2: Make size_to_clusters() return uint64_t
Sadly, some images may have more clusters than what can be represented
using a plain int. We should be prepared for that case (in
qcow2_check_refcounts() we actually were trying to catch that case, but
since size_to_clusters() truncated the returned value, that check never
did anything useful).

target-arm: Use tcg_gen_extrh_i64_i32
Usually, eliminate an operation from the translator by combining
a shift with an extract.
In the case of gen_set_NZ64, we don't need a boolean value for cpu_ZF,
merely a non-zero value. Given that we can extract both halves of a
64-bit input in one call, this simplifies the code.

target-arm: Eliminate unnecessary zero-extend in disas_bitfield
For !SF, this initial ext32u can't be optimized away by the
current TCG code generator. (It would require backward bit
liveness propagation.)
But since the range of bits for !SF are already constrained by
unallocated_encoding, we'll never reference the high bits anyway.

target-arm: Share all common TCG temporaries
This is a bug fix for aarch64. At present, we have branches using
the 32-bit (translate.c) versions of cpu_[NZCV]F, but we set the flags
using the 64-bit (translate-a64.c) versions of cpu_[NZCV]F. From
the view of the TCG code generator, these are unrelated variables.
The bug is hard to see because we currently only read these variables
from branches, and upon reaching a branch TCG will first spill live
variables and then reload the arguments of the branch. Since the
32-bit versions were never live until reaching the branch, we'd re-read
the data that had just been spilled from the 64-bit versions.
There is currently no such problem with the cpu_exclusive_* variables,
but there's no point in tempting fate.

target-sh4: improve shad instruction
The SH4 shad instruction can shift in both direction, depending on the
sign of the shift. This is currently implemented using branches, which
is not really efficient and prevents the optimizer to do its job. In
practice it is often used with a constant loaded in a register just
before.
Simplify the implementation by computing both the value shifted to the
left and to the right, and then selecting the correct one with a
movcond. As with a negative value the shift amount can go up to 32 which
is undefined, we shift the value in two steps.

target-sh4: improve cmp/str instruction
Instead of testing bytes one by one, we can use the following trick
from https://graphics.stanford.edu/~seander/bithacks.html:
haszero(v) = (v - 0x01010101) & ~v & 0x80808080
The subexpression v - 0x01010101, evaluates to a high bit set in any
byte whenever the corresponding byte in v is zero or greater than 0x80.
The sub-expression ~v & 0x80808080 evaluates to high bits set in bytes
where the byte of v doesn't have its high bit set (so the byte was less
than 0x80). Finally, by ANDing these two sub-expressions the result is
the high bits set where the bytes in v were zero, since the high bits
set due to a value greater than 0x80 in the first sub-expression are
masked off by the second.

All targets ignore it for now, and all other callers pass "false".
This will allow targets who wish to split the mmu index between

prepending a spurious comma at the beginning of the list, or quoting
values unnecessarily. This patch provides the following changes:
* write and id=, if the option has an id
* do not print separator before the first element
* do not quote string arguments
* properly escape commas (,) for QEMU

i6300esb: fix timer overflow
We use muldiv64() to compute the time to wait:
timeout = muldiv64(get_ticks_per_sec(), timeout, 33000000);
but get_ticks_per_sec() is 10^9 (30 bit value) and timeout
is a 35 bit value.
Whereas muldiv64 is:
uint64_t muldiv64(uint64_t a, uint32_t b, uint32_t c)
So we loose 3 bits of timeout.
Swapping get_ticks_per_sec() and timeout fixes it.
We can also replace it by a multiplication by 30 ns,
but this changes PCI clock frequency from 33MHz to 33.333333MHz
and we need to do this on all the QEMU PCI devices (later...)

xen/pt: Remove XenPTReg->data field.
We do not want to have two entries to cache the guest configuration
registers: XenPTReg->data and dev.config. Instead we want to use
only the dev.config.
To do without much complications we rip out the ->data field
and replace it with an pointer to the dev.config. This way we
have the type-checking (uint8_t, uint16_t, etc) and as well
and pre-computed location.
Alternatively we could compute the offset in dev.config by
using the XenPTRRegInfo and XenPTRegGroup every time but
this way we have the pre-computed values.
This change also exposes some mis-use:
- In 'xen_pt_status_reg_init' we used u32 for the Capabilities Pointer
register, but said register is an an u16.
- In 'xen_pt_msgdata_reg_write' we used u32 but should have only use u16.

It should never happen, but in case it does (an developer adds

size) we want to report. The code will only write up to
reg->size so there is no runtime danger of the register spilling
across other ones - however to catch this sort of thing
we still return an error.

xen/pt: Sync up the dev.config and data values.
For a passthrough device we maintain a state of emulated
registers value contained within d->config. We also consult
the host registers (and apply ro and write masks) whenever
the guest access the registers. This is done in xen_pt_pci_write_config
and xen_pt_pci_read_config.
Also in this picture we call pci_default_write_config which
updates the d->config and if the d->config[PCI_COMMAND] register
has PCI_COMMAND_MEMORY (or PCI_COMMAND_IO) acts on those changes.
On startup the d->config[PCI_COMMAND] are the host values, not
what the guest initial values should be, which is exactly what
we do _not_ want to do for 64-bit BARs when the guest just wants
to read the size of the BAR. Huh you say?
To get the size of 64-bit memory space BARs, the guest has
to calculate ((BAR[x] & 0xFFFFFFF0) + ((BAR[x+1] & 0xFFFFFFFF) << 32))
which means it has to do two writes of ~0 to BARx and BARx+1.
prior to this patch and with XSA120-addendum patch (Linux kernel)
the PCI_COMMAND register is copied from the host it can have
PCI_COMMAND_MEMORY bit set which means that QEMU will try to
update the hypervisor's P2M with BARx+1 value to ~0 (0xffffffff)
(to sync the guest state to host) instead of just having
xen_pt_pci_write_config and xen_pt_bar_reg_write apply the
proper masks and return the size to the guest.
To thwart this, this patch syncs up the host values with the
guest values taking into account the emu_mask (bit set means
we emulate, PCI_COMMAND_MEMORY and PCI_COMMAND_IO are set).
That is we copy the host values - masking out any bits which
we will emulate. Then merge it with the initial emulation register
values. Lastly this value is then copied both in
dev.config _and_ XenPTReg->data field.
There is also reg->size accounting taken into consideration
that ends up being used in patch.
xen/pt: Check if reg->init function sets the 'data' past the reg->size
This fixes errors such as these:
(XEN) memory_map:add: dom2 gfn=fffe0 mfn=fbce0 nr=20
(DEBUG) 189 pci dev 04:0 BAR16 wrote ~0.
(DEBUG) 200 pci dev 04:0 BAR16 read 0x0fffe0004.

[The DEBUG is to illustate what the hvmloader was doing]
Also we swap from xen_host_pci_long to using xen_host_pci_get_[byte,word,long].
Otherwise we get:
xen_pt_config_reg_init: Offset 0x0004 mismatch! Emulated=0x0000, host=0x2300017, syncing to 0x2300014.
xen_pt_config_reg_init: Error: Offset 0x0004:0x2300014 expands past register size(2)!
which is not surprising. We read the value as an 32-bit (from host),
then operate it as a 16-bit - and the remainder is left unchanged.
We end up writing the value as 16-bit (so 0014) to dev.config
(as we use proper xen_set_host_[byte,word,long] so we don't spill
to other registers) but in XenPTReg->data it is as 32-bit (0x2300014)!
It is harmless as the read/write functions end up using an size mask
and never modify the bits past 16-bit (reg->size is 2).
This patch fixes the warnings by reading the value using the
proper size.
Note that the check for size is still left in-case the developer
sets bits past the reg->size in the ->init routines. The author
tried to fiddle with QEMU_BUILD_BUG to make this work but failed.

xen/pt: Use xen_host_pci_get_[byte|word] instead of dev.config
During init time we treat the dev.config area as a cache
of the host view. However during execution time we treat it
as guest view (by the generic PCI API). We need to sync Xen's
code to the generic PCI API view. This is the first step
by replacing all of the code that uses dev.config or
pci_get_[byte|word] to get host value to actually use the
xen_host_pci_get_[byte|word] functions.
Interestingly in 'xen_pt_ptr_reg_init' we also needed to swap
reg_field from uint32_t to uint8_t - since the access is only
for one byte not four bytes. We can split this as a seperate
patch however we would have to use a cast to thwart compiler
warnings in the meantime.
We also truncated 'flags' to 'flag' to make the code fit within
the 80 characters.

xen: use errno instead of rc for xc_domain_add_to_physmap
In Xen 4.6 commit cd2f100f0f61b3f333d52d1737dd73f02daee592
"libxc: Fix do_memory_op to return negative value on errors"
made the libxc API less odd-ball: On errors, return value is
-1 and error code is in errno. On success the return value
is either 0 or an positive value.
Since we could be running with an old toolstack in which the
Exx value is in rc or the newer, we add an wrapper around
the xc_domain_add_to_physmap (called xen_xc_domain_add_to_physmap)
which will always return the EXX.
Xen 4.6 did not change the libxc functions mentioned (same parameters)
so we piggyback on the fact that Xen 4.6 has a new function:
commit 504ed2053362381ac01b98db9313454488b7db40 "tools/libxc: Expose
new hypercall xc_reserved_device_memory_map" and check for that.

xen/HVM: atomically access pointers in bufioreq handling
The number of slots per page being 511 (i.e. not a power of two) means
that the (32-bit) read and write indexes going beyond 2^32 will likely
disturb operation. The hypervisor side gets I/O req server creation
extended so we can indicate that we're using suitable atomic accesses
where needed, allowing it to atomically canonicalize both pointers when
both have gone through at least one cycle.
The Xen side counterpart (which is not a functional prereq to this
change, albeit a build one) went in already (commit b7007bc6f9).

igd gfx passthrough: create a isa bridge
Currently IGD drivers always need to access PCH by 1f.0. But we
don't want to poke that directly to get ID, and although in real
world different GPU should have different PCH. But actually the
different PCH DIDs likely map to different PCH SKUs. We do the
same thing for the GPU. For PCH, the different SKUs are going to
be all the same silicon design and implementation, just different
features turn on and off with fuses. The SW interfaces should be
consistent across all SKUs in a given family (eg LPT). But just
same features may not be supported.
Most of these different PCH features probably don't matter to the
Gfx driver, but obviously any difference in display port connections
will so it should be fine with any PCH in case of passthrough.
So currently use one PCH version, 0x8c4e, to cover all HSW(Haswell)
scenarios, 0x9cc3 for BDW(Broadwell).

error: On abort, report where the error was created
This is particularly useful when we abort in error_propagate(),
because there the stack backtrace doesn't lead to where the error was
created. Looks like this:
Unexpected error in parse_block_error_action() at .../qemu/blockdev.c:322:
qemu-system-x86_64: -drive if=none,werror=foo: 'foo' invalid write error action
Aborted (core dumped)
Note: to get this example output, I monkey-patched drive_new() to pass
&error_abort to blockdev_init().
To keep the error handling boiler plate from growing even more, all
error_setFOO() become macros expanding into error_setFOO_internal()
with additional __FILE__, __LINE__, __func__ arguments. Not exactly
pretty, but it works.
The macro trickery breaks down when you take the address of an
error_setFOO(). Fortunately, we do that in just one place: qemu-ga's
Windows VSS provider and requester DLL wants to call
error_setg_win32() through a function pointer "to avoid linking glib
to the DLL". Use error_setg_win32_internal() there. The use of the
function pointer is already wrapped in a macro, so the churn isn't
bad.
Code size increases by some 35KiB for me (0.7%). Tolerable. Could be
less if we passed relative rather than absolute source file names to
the compiler, or forwent reporting __func__.

qga/vss-win32: Document the DLL requires non-null errp
requester.cpp uses this pattern to receive an error and pass it on to
the caller (err_is_set() macro peeled off for clarity):
... code that may set errset->errp ...
if (errset->errp && *errset->errp) {
... handle error ...
}
This breaks when errset->errp is null. As far as I can tell, it
currently isn't, so this is merely fragile, not actually broken.
The robust way to do this is to receive the error in a local variable,
then propagate it up, like this:
Error *err = NULL;
... code that may set err ...
if (err)
... handle error ...
error_propagate(errset->errp, err);
}

qga: Clean up unnecessarily dirty casts
qga_vss_fsfreeze() casts error_set_win32() from
void (*)(Error **, int, ErrorClass, const char *, ...)
to
void (*)(void **, int, int, const char *, ...)
The result is later called. Since the two types are not compatible,
the call is undefined behavior. It works in practice anyway.
However, there's no real need for trickery here. Clean it up as
follows:
* Declare struct Error, and fix the first parameter.
* Switch to error_setg_win32(). This gets rid of the troublesome
ErrorClass parameter. Requires converting error_setg_win32() from
macro to function, but that's trivially easy, because this is the
only user of error_set_win32().

hw/pci: fix pci_update_mappings() trace events
The current trace prototypes and (matching) trace calls lead to
"unorthodox" PCI BDF notation in at least the stderr trace backend. For
example, the four BARs of a QXL video card at 00:01.0 (bus 0, slot 1,
function 0) are traced like this (PID and timestamps removed):
pci_update_mappings_add d=0x7f14a73bf890 00:00.1 0,0x84000000+0x4000000
pci_update_mappings_add d=0x7f14a73bf890 00:00.1 1,0x80000000+0x4000000
pci_update_mappings_add d=0x7f14a73bf890 00:00.1 2,0x88200000+0x2000
pci_update_mappings_add d=0x7f14a73bf890 00:00.1 3,0xd060+0x20
The slot and function values are in reverse order.
Stick with the conventional BDF notation.

pc: memhotplug: fix incorrectly set reserved-memory-end
reserved-memory-end tells firmware address from which
it could start treating memory as PCI address space
and map PCI BARs after it to avoid collisions with
RAM.
Currently it is incorrectly pointing to address where
hotplugged memory range starts which could redirect
hotplugged RAM accesses to PCI BARs when firmware
maps them over RAM or viceverse.
Fix this by pointing reserved-memory-end to the end
of memory hotplug area.

pci: Fix pci_device_iommu_address_space() bus propagation
he current code walks up the bus tree for an iommu, however it passes
to the iommu_fn() callback the bus/devfn of the immediate child of
the level where the callback was found, rather than the original
bus/devfn where the search started from.
This prevents iommu's like POWER8 (and in fact also Q35) to properly
provide an address space for a subset of devices that aren't immediate
children of the iommu.
PCIe carries the originator bdfn acccross to the iommu on all DMA
transactions, so we must be able to properly identify devices at all
levels.
This changes the function pci_device_iommu_address_space() to pass
the original pointers to the iommu_fn() callback instead.

cutils: work around platform differences in strto{l,ul,ll,ull}
Linux returns 0 if no conversion was made, while OS X and presumably
the BSDs return EINVAL. The OS X convention rejects more invalid
inputs, so convert to it and adjust the test case.
Windows returns 1 from strtoul and strtoull (instead of -1) for
negative out-of-range input; fix it up.

cpu-exec: fix lock hierarchy for user-mode emulation
tb_lock has to be taken inside the mmap_lock (example:
tb_invalidate_phys_range is called by target_mmap), but
tb_link_page is taking the mmap_lock and it is called
with the tb_lock held.
To fix this, take the mmap_lock in tb_find_slow, not
in tb_link_page.

spinlock is only used in two cases:

* mem_helper.c: for lock helper in target-i386 (which seems broken).
It's a pthread_mutex_t in user-mode, so we can use QemuMutex directly,
with an #ifdef. The #ifdef will be removed when multithreaded TCG
will need the mutex as well.

configure: Add support for jemalloc
This adds "--enable-jemalloc" and "--disable-jemalloc" to allow linking
to jemalloc memory allocator.
We have already tcmalloc support,
but it seem to not working well with a lot of iothreads/disks.
The main problem is that tcmalloc use a shared thread cache of 16MB
by default.
With more threads, this cache is shared, and some bad garbage collections
can occur if the cache is too low.
It's possible to tcmalloc cache increase it with a env var:
TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES=256MB
With default 16MB, performances are really bad with more than 2 disks.
Increasing to 256MB, it's helping but still have problem with 16 disks/iothreads.
Jemalloc don't have performance problem with default configuration.
Here the benchmark results in iops of 1 qemu vm randread 4K iodepth=32,
with rbd block backend (librbd is doing a lot of memory allocation),

rcu: init rcu_registry_lock after fork
We were unlocking this lock after fork, which is wrong since

Makefile.target: include top level build dir in vpath
Using ccache with CCACHE_BASEDIR set to $(SRC_PATH) or a parent will
rewrite all absolute paths to relative paths. This interacts poorly with
QEMU's two-level build directory scheme. For example, lets say
BUILD_DIR=$(SRC_PATH)/build so build/blockdev.d will contain:
blockdev.o: ../blockdev.c ../include/sysemu/block-backend.h \
Now the target build under build/x86_64-softmmu or similar will depend
on ../blockdev.o which in turn will get make to source ../blockdev.d to
check its dependencies. Since make always considers paths relative to
the current working directory rather than the makefile the path appeared
in the relative path to ../blockdev.c is useless.
This change simply adds the top level build directory to vpath so paths
relative to the source directory, top build directory, and target build
directory all work just fine.

tcg: signal-free qemu_cpu_kick
Signals are slow and do not exist on Win32. The previous patches
have done most of the legwork to introduce memory barriers (some
of them were even there already for the sake of Windows!) and
we can now set the flags directly in the iothread.
qemu_cpu_kick_thread is not used anymore on TCG, since the TCG thread is
never outside usermode while the CPU is running (not halted). Instead run
the content of the signal handler (now in qemu_cpu_kick_no_halt) directly.
qemu_cpu_kick_no_halt is also used in qemu_mutex_lock_iothread to avoid
the overhead of qemu_cond_broadcast.

use qemu_cpu_kick instead of cpu_exit or qemu_cpu_kick_thread
Use the same API to trigger interruption of a CPU, no matter if
under TCG or KVM. There is no difference: these calls come from
the CPU thread, so the qemu_cpu_kick calls will send a signal
to the running thread and it will be processed synchronously,
just like a call to cpu_exit. The only difference is in the
overhead, but neither call to cpu_exit (now qemu_cpu_kick)
is in a hot path.

i8257: rewrite DMA_schedule to avoid hooking into the CPU loop
The i8257 DMA controller uses an idle bottom half, which by default
does not cause the main loop to exit. Therefore, the DMA_schedule
function is there to ensure that the CPU relinquishes the iothread
mutex to the iothread.
However, this is not enough since the iothread will call
aio_compute_timeout() and go to sleep again. In the iothread
world, forcing execution of the idle bottom half is much simpler,
and only requires a call to qemu_notify_event(). Do it, removing
the need for the "cpu_request_exit" pseudo-irq. The next patch
will remove it.

hw/intc/arm_gic_common: Configure IRQs as NS if doing direct NS kernel boot
If we directly boot a kernel in NonSecure on a system where the GIC
supports the security extensions then we must cause the GIC to
configure its interrupts into group 1 (NonSecure) rather than the
usual group 0, and with their initial priority set to the highest
NonSecure priority rather than the usual highest Secure priority.
Otherwise the guest kernel will be unable to use any interrupts.
Implement this behaviour, controlled by a flag which we set if
appropriate when the ARM bootloader code calls our ARMLinuxBootIf
interface callback.

hw/arm: new interface for devices which need to behave differently for kernel boot
For ARM we have a little minimalist bootloader in hw/arm/boot.c which
takes the place of firmware if we're directly booting a Linux kernel.
Unfortunately a few devices need special case handling in this situation
to do the initialization which on real hardware would be done by
firmware. (In particular if we're booting a kernel in NonSecure state
then we need to make a TZ-aware GIC put all its interrupts into Group 1,
or the guest will be unable to use them.)
Create a new QOM interface which can be implemented by devices which
need to do something different from their default reset behaviour.
The callback will be called after machine initialization and before
first reset.

the latter holding the active priority bits for Group 1 interrupts
(usually Nonsecure interrupts), and the Nonsecure view of the
GICC_APR<n> is the second half of the GICC_NSAPR<n> registers.
Turn our half-hearted implementation of APR<n> into a proper
implementation of both APR<n> and NSAPR<n>:
* Add the underlying state for NSAPR<n>
* Make sure APR<n> aren't visible for pre-GICv2
* Implement reading of NSAPR<n>
* Make non-secure reads of APR<n> behave correctly
* Implement writing to APR<n> and NSAPR<n>

hw/intc/arm_gic: Running priority is group priority, not full priority
Priority values for the GIC are divided into a "group priority"
and a "subpriority" (with the division being determined by the
binary point register). The running priority is only determined
by the group priority of the active interrupts, not the
subpriority. In particular, this means that there can't be more
than one active interrupt at any particular group priority.

armv7m_nvic: Implement ICSR without using internal GIC state
Change the implementation of the Interrupt Control and State Register
in the v7M NVIC to not use the running_irq and last_active internal
state fields in the GIC. These fields don't correspond to state in
a real GIC and will be removed soon.
The changes to the ICSR are:
* the VECTACTIVE field is documented as identical to the IPSR[8:0]
field, so implement it that way
* implement RETTOBASE via looking at the active state bits

cpus.c: qemu_mutex_lock_iothread fix race condition at cpu thread init
When QEMU starts the RCU thread executes qemu_mutex_lock_thread
causing error "qemu:qemu_cpu_kick_thread: No such process" and exits.
This isn't occur frequently but in glibc the thread id can exist and
this not guarantee that the thread is on active/running state. If is
inserted a sleep(1) after newthread assignment [1] the issue appears.
So not make assumption that thread exist if first_cpu->thread is set
then change the validation of cpu to created that is set into cpu
threads (kvm, tcg, dummy).

s390/sclp: ignore memory hotplug operations if it is disabled
If no memory hotplug device was created, the sclp command facility is

if any such command is executed.
This gets rid of these ugly asserts that could have been triggered

s390/sclp: temporarily fix unassignment/reassignment of memory subregions
Commit 374f2981d1f1 ("memory: protect current_map by RCU") broke
unassignment of standby memory on s390x. Looks like that the new
parallelism allows races with our (semi broken) memory hotplug code. The
flatview_unref() can now be executed after our unparenting. Therefore
memory_region_unref() tries to unreference the MemoryRegion itself instead
of the parent.
In theory, MemoryRegions are now bound to separate devices that control
their lifetime. We don't have this yet, so we really want to control their
lifetime manually.
This patch fixes it temporarily, until we have a proper rework. The only
drawback is that they won't pop up in "info qom-tree", but that's better
than qemu crashes.
We have to release the reference to a memory region after a
memory_region_find, as it automatically takes a reference. As we're now
able to reassign memory, the MemoryRegion is in fact deleted (otherwise
vmstate_register_ram() would complain).

s390/sclp: rework sclp event facility initialization + device realization
The current code only works by chance. The event facility is a sysbus
device, but specifies in its class structure as parent the DeviceClass
(instead of a device class).
The init function in return lies therefore at the same position as
the init function of SysBusDeviceClass and gets triggered instead -
a very bad idea of doing that (e.g. the parameter types don't match).
Let's bring the initialization code up to date, initializing the event
facility + child events in .instance_init and moving the realization of
the child events out of the init call, into the realization step.
Device realization is now automatically performed when the event facility
itself is realized. That realization implicitly triggers realization of
the child bus, which in turn initializes the events.
Please note that we have to manually propagate the realization of the bus
children, common code still has a TODO set for that task.

Let's get rid of this strange local variable + irq logic and

We could introduce proper QOM class + state for the cpu hotplug device,
however that would result in too much overhead for a simple
"trigger_signal" function.
Also remove one unnecessary class function initialization.

s390x/kvm: make setting of in-kernel irq routes more efficient
When we add new adapter routes we call kvm_irqchip_add_route() for every
virtqueue and in the same step also do the KVM_SET_GSI_ROUTING ioctl.
This is unnecessary costly as the interface allows us to set multiple
routes in one go. Let's first add all routes to the table stored in the
global kvm_state and then do the ioctl to commit the routes to the
in-kernel irqchip.
This saves us several ioctls to the kernel where for each call a list
is reallocated and populated.

pc-bios/s390-ccw: Device detection in higher subchannel sets
If no bootdevice was specified, we try to autodetect a suitable IPL
device. Current code only searched in subchannel set 0; extend this
search to higher subchannel sets as well.

s390x/event-facility: fix location of receive mask
For read event mask, we assumed that the layout of the sccb was
|sccb header|event buffer header|receive mask|...|
The correct layout, however, is
|sccb header|receive mask|...|
as in-buffer and
|sccb header|event buffer header|...|
as out-buffer.
Fix this: This makes selective read work.

s390x/css: start with cleared cstat/dstat
When executing the start function, we should start with a clear state
regarding subchannel and device status; it is easy to forget updating one
of them after the ccw has been processed.
Note that we don't need to care about resetting the various control
fields: They are cleared by tsch(), and if they were still pending,
we wouldn't be able to execute the start function in the first
place.
Also note that we don't want to clear cstat/dstat if a suspended
subchannel is resumed.
This fixes a bug where we would continue to present channel-program
check in cstat even though later ccw requests for the subchannel
finished without error (i.e. cstat should be 0).

Make pow2ceil() and pow2floor() inline
Since the pow2floor() function is now used in a hot code path,
make it inline; for consistency, provide pow2ceil() as an inline
function too.
Because these functions use ctz64() we have to put the inline
versions into host-utils.h, so they have access to ctz64(),
and move the inline is_power_of_2() along with them.
We then need to include host-utils.h from qemu-common.h so that
the files which use these functions via qemu-common.h still have
access to them.

hw/pci: Use pow2ceil() rather than hand-calculation
A couple of places in hw/pci use an inline calculation to round a
size up to the next largest power of 2. We have a utility routine
for this, so use it.
(The behaviour of the old code is different if the size value
is 0 -- it would leave it as 0 rather than rounding up to 1,
but in both cases we know the size can't be 0.
In the case where the size value had bit 31 set, the old code
would invoke undefined behaviour; the new code will give a
result of 0. Presumably that could never happen either.)

target-arm/arm-semi.c: Factor out repeated 'return env->regs[0]'
Factor out a repeated pattern in the semihosting code:
gdb_do_syscall(arm_semi_cb, "system,%s", arg0, (int)arg1+1);
/* arm_semi_cb sets env->regs[0] to the syscall return value */
return env->regs[0];
For A64 the return value will go in a different register; pull
the sequence out into its own function that passes the return
value in a static variable rather than overloading regs[0]
for the purpose, so the code will work on both A32/T32 and A64.
Note that the lack-of-synchronization bug noted in the FIXME
comment is not introduced by this commit, but was already present.

arm: Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T).

docs: document how to configure the qcow2 L2/refcount caches
QEMU has options to configure the size of the L2 and refcount
caches for the qcow2 format. However, choosing the right sizes for
a particular disk image is not a straightforward operation since
the ratio between the cache size and the allocated disk space is
not obvious and depends on the size of the cluster and the refcount
entries.
This document attempts to give an overview of both caches and how to
configure their sizes.

qcow2: add option to clean unused cache entries after some time
This adds a new 'cache-clean-interval' option that cleans all qcow2
cache entries that haven't been used in a certain interval, given in
seconds.
This allows setting a large L2 cache size so it can handle scenarios
with lots of I/O and at the same time use little memory during periods
of inactivity.
This feature currently relies on MADV_DONTNEED to free that memory, so
it is not useful in systems that don't follow that behavior.

qcow2: mark the memory as no longer needed after qcow2_cache_empty()
After having emptied the cache, the data in the cache tables is no
longer useful, so we can tell the kernel that we are done with it. In
Linux this frees the resources associated with it.
The effect of this can be seen in the HMP commit operation: it moves
data from the top to the base image (and fills both caches), then it
empties the top image. At this point the data in that cache is no
longer needed so it's just wasting memory.

iotests: Do not suppress segfaults in bash tests
Currently, if a qemu/qemu-io/qemu-img/qemu-nbd invocation receives a
segmentation fault, that message is invisible in most cases since the
output is generally filtered and bash suppresses the segmentation fault
notice for any but the last element of a pipe.
Most of the time, the test will then fail anyway because of missing
output, but not necessarily (as happened with test 82 recently).
Fix this by making the corresponding environment variables point to
wrapper functions which execute the respective command in a subshell.
Giving options to qemu/qemu-io/qemu-img and path names with spaces were
broken for the Python tests; this patch "accidentally" fixes that.

qemu-iotests: disable default qemu devices for cross-platform compatibility
This patch fixes an io test suite issue that was introduced with the
commit c88930a6866e74953e931ae749781e98e486e5c8 'qemu-char: Permit only
a single "stdio" character device'. The option supresses the creation of
default devices such as the floopy and cdrom. Output files for test case
067, 071, 081 and 087 need to be updated to accommodate this change.
Use virtio-blk instead of virtio-blk-pci as the device driver for test
case 067. For virtio-blk-pci is the same with virtio-blk as device
driver but other platform such as s390 may not recognize the virtio-blk-pci.
The default devices differ across machines. As the qemu output often
contains these devices (or events for them, like opening a CD tray on
reset), the reference output currently is rather machine-specific.
All existing qemu tests explicitly configure the devices they're working
with, so just pass -nodefaults to qemu by default to disable the default
devices. Update the reference outputs accordingly.

qemu-iotests: qemu machine type support
This patch adds qemu machine type support to the io test suite.
Based on the qemu default machine type and alias of the default machine
type the reference output file can now vary from the default to a
machine specific output file if necessary. When using a machine specific
reference file if the default machine has an alias then use the alias as the output
file name otherwise use the default machine name as the output file name.

qapi: Simplify error reporting for array types
check_type() first checks and peels off the array type, then checks
the element type. For two out of four error messages, it takes pains
to report errors for "array of T" instead of just T. Odd. Let's
examine the errors.
* Unknown element type, e.g.
tests/qapi-schema/args-array-unknown.json:
Member 'array' of 'data' for command 'oops' uses unknown type
'array of NoSuchType'
To make sense of this, you need to know that 'array of NoSuchType'
refers to '[NoSuchType]'. Easy enough. However, simply reporting
Member 'array' of 'data' for command 'oops' uses unknown type
'NoSuchType'
is at least as easy to understand.
* Element type's meta-type is inadmissible, e.g.
tests/qapi-schema/returns-whitelist.json:
'returns' for command 'no-way-this-will-get-whitelisted' cannot
use built-in type 'array of int'
'array of int' is technically not a built-in type, but that's
pedantry. However, simply reporting
'returns' for command 'no-way-this-will-get-whitelisted' cannot
use built-in type 'int'
avoids the issue, and is at least as easy to understand.
* The remaining two errors are unreachable, because the array checking
ensures that value is a string.
Thus, reporting some errors for "array of T" instead of just T works,
but doesn't really improve things. Drop it.

qapi: Document that input visitor semantics are prone to leaks
Most functions that can return a pointer or set an Error ** value
are decent enough to guarantee a NULL return when reporting an error.
Not so with our generated qapi visitor functions. If the caller
is not careful to clean up partially-allocated objects on error,
then the caller suffers a memory leak.
Properly fixing it is probably complex enough to save for a later
day, so merely document it for now.

qapi: Generate a nicer struct for flat unions
The struct generated for a flat union is weird: the members of its
base are at the end, except for the union tag, which is at the
beginning.
Example: qapi-schema-test.json has
{ 'struct': 'UserDefUnionBase',
'data': { 'string': 'str', 'enum1': 'EnumOne' } }
{ 'union': 'UserDefFlatUnion',
'base': 'UserDefUnionBase',
'discriminator': 'enum1',
'data': { 'value1' : 'UserDefA',
'value2' : 'UserDefB',
'value3' : 'UserDefB' } }
We generate:
struct UserDefFlatUnion
{
EnumOne enum1;
union {
void *data;
UserDefA *value1;
UserDefB *value2;
UserDefB *value3;
};
char *string;
};
Change to put all base members at the beginning, unadulterated. Not
only is this easier to understand, it also permits casting the flat
union to its base, if that should become useful.
We now generate:
struct UserDefFlatUnion
{
/* Members inherited from UserDefUnionBase: */
char *string;
EnumOne enum1;
/* Own members: */
union { /* union tag is @enum1 */
void *data;
UserDefA *value1;
UserDefB *value2;
UserDefB *value3;
};
};

Example, adapted from qapi-schema-test.json:

'data': { 'kind': 'str', 'enum1': 'EnumOne' } }
We generate:
struct UserDefFlatUnion
{
EnumOne kind;
union {
void *data;
UserDefA *value1;
UserDefB *value2;
UserDefB *value3;
};
char *kind;
};

qapi: Drop unused and useless parameters and variables
gen_sync_call()'s parameter indent is useless: gen_sync_call() uses it
only as optional argument for push_indent() and pop_indent(), their
default is four, and gen_sync_call()'s only caller passes four. Drop
the parameter.
gen_visitor_input_containers_decl()'s parameter obj is always
"QOBJECT(args)". Use that, and drop the parameter.
Drop unused parameters of gen_marshal_output(),
gen_marshal_input_decl(), generate_visit_struct_body(),
generate_visit_list(), generate_visit_enum(), generate_declaration(),
generate_enum_declaration(), generate_decl_enum().
Drop unused variables in generate_event_enum_lookup(),
generate_enum_lookup(), generate_visit_struct_fields(), check_event().

qapi-event: Clean up how name of enum QAPIEvent is made
Use c_name() instead of ad hoc code. Doesn't upcase the -p prefix,
which is an improvement in my book. Unbreaks prefix containing '.',
but other funny characters remain broken. To be fixed next.

qapi: Clean up cgen() and mcgen()
Commit 05dfb26 added eatspace stripping to mcgen(). Move it to
cgen(), just in case somebody gets tempted to use cgen() directly
instead of via mcgen().
cgen() indents blank lines. No such lines get generated right now,
but fix it anyway.
We use triple-quoted strings for program text, like this:
'''
Program text
any number of lines
'''
Keeps the program text relatively readable, but puts an extra newline
at either end. mcgen() "fixes" that by dropping the first and last
line outright. Drop only the newlines.
This unmasks a bug in qapi-commands.py: four quotes instead of three.
Fix it up.
Output doesn't change

rtl8139: Fix receive buffer overflow check
rtl8139_do_receive() tries to check for the overflow condition
by making sure that packet_size + 8 does not exceed the
available buffer space. The issue here is that RxBuffAddr,
used to calculate available buffer space, is aligned to a
a 4 byte boundry after every update. So it is possible that
every packet ends up being slightly padded when written
to the receive buffer. This padding is not taken into
account when checking for overflow and we may end up missing
the overflow condition can causing buffer overwrite.
This patch takes alignment into consideration when
checking for overflow condition.

build: qemu-ga: fix VSS dependencies
Currently VSS dll/tlb files for use in w32 builds are only built as a
result of having been added to the general 'tools' target alongside
qemu-ga. This is fine for default make target, but if we build
qemu-ga directly via `make qemu-ga.exe`, the VSS files are not
created.
Fix this by moving the VSS dependencies to qemu-ga.exe directly.
With this move we can move the VSS files back out of 'tools',
and drop the extra handling from MSI target in Makefile.
Now we can build qemu-ga MSI package with:
./configure ...
make qemu-ga.exe
make msi
or simply:
./configure ...
make msi
and no longer need to do a full build beforehand.

configure: qemu-ga: explicitly enable qemu-ga MSI support when probed
Currently, if we don't explicitly disable support for MSI installer
via --disable-guest-agent-msi, the configure variable that tracks
the flag, 'guest_agent_msi', never gets set unless one of the probes
fails. Subsequent code then treats this unset value the same as if it
were a "yes" value (via != "no" style checks).
Instead, set the default "yes" value explicitly after the probes, then
make subsequent code expect the values to be set.
This makes it easier to report on whether or not MSI support was
enabled via probe by looking at the ./configure summary.

configure: qemu-ga: move MSI installer probe after qga probe
MSI probe assumes that qemu-ga support has been probed already, but in
cases where --enable-guest-agent/--disable-guest-agent have not been
passed to configure, qemu-ga support may end up getting enabled later,
as is the case with w32 builds. This leads to MSI probe prematurely
reporting error due to lack of qemu-ga support.
Fix this by moving MSI installer probe after the final qga probes.

qemu-ga: Prevent QEMU-GA VSS provider from being unregistered on MSI reinstall
Previously, running the .msi would unregister the QEMU GA VSS service if QEMU GA was already installed on the machine, and then register it only if QEMU GA was NOT previously installed. This behavior caused the service to be registered only after the INITIAL installation, and any subsequent run of the .msi (to redo, repair, or upgrade the installation) ended in the service being unregistered.
Now, the VSS service is still unregistered if QEMU GA is already installed (so that a fix or an update could be performed) but then it is registered again (if the GA is not being uninstalled) thus finishing the repair/upgrade correctly. Additionally, downgrading is now prevented. If a user would like to downgrade a version, he/she must uninstall the newer version first.

vnc: fix memory corruption (CVE-2015-5225)
The _cmp_bytes variable added by commit "bea60dd ui/vnc: fix potential
memory corruption issues" can become negative. Result is (possibly
exploitable) memory corruption. Reason for that is it uses the stride
instead of bytes per scanline to apply limits.
For the server surface is is actually fine. vnc creates that itself,
there is never any padding and thus scanline length always equals stride.
For the guest surface scanline length and stride are typically identical
too, but it doesn't has to be that way. So add and use a new variable
(guest_ll) for the guest scanline length. Also rename min_stride to
line_bytes to make more clear what it actually is. Finally sprinkle
in an assert() to make sure we never use a negative _cmp_bytes again.

Now we have the ability to flush the TLB only for specific MMU indexes,
update the AArch64 TLB maintenance instruction implementations to only
flush the parts of the TLB they need to, rather than doing full flushes.
We take the opportunity to remove some duplicate functions (the per-asid
tlb ops work like the non-per-asid ones because we don't support
flushing a TLB only by ASID) and to bring the function names in line
with the architectural TLBI operation names.

Guest CPU TLB maintenance operations may be sufficiently
specialized to only need to flush TLB entries corresponding
to a particular MMU index. Implement cputlb functions for
this, to avoid the inefficiency of flushing TLB entries
which we don't need to.

tcg/ppc: Improve unaligned load/store handling on 64-bit backend
Currently, we get to the slow path for any unaligned access in the
backend, because we effectively preserve the bottom address bits
below the alignment requirement when comparing with the TLB entry,
so any non-0 bit there will cause the compare to fail.
For the same number of instructions, we can instead add the access
size - 1 to the address and stick to clearing all the bottom bits.
That means that normal unaligned accesses will not fallback (the HW
will handle them fine). Only when crossing a page boundary well we
end up having a mismatch because we'll end up pointing to the next
page which cannot possibly be in that same TLB entry.

tcg/i386: use softmmu fast path for unaligned accesses
Softmmu unaligned load/stores currently goes through through the slow
path for two reasons:
- to support unaligned access on host with strict alignement
- to correctly handle accesses crossing pages
x86 is only concerned by the second reason. Unaligned accesses are
avoided by compilers, but are not uncommon. We therefore would like
to see them going through the fast path, if they don't cross pages.
For that we can use the fact that two adjacent TLB entries can't contain
the same page. Therefore accessing the TLB entry corresponding to the
first byte, but comparing its content to page address of the last byte
ensures that we don't cross pages. We can do this check without adding
more instructions in the TLB code (but increasing its length by one
byte) by using the LEA instruction to combine the existing move with the
size addition.
On an x86-64 host, this gives a 3% boot time improvement for a powerpc
guest and 4% for an x86-64 guest.

tcg/optimize: track const/copy status separately
Instead of using an enum which could be either a copy or a const, track
them separately. This will be used in the next patch.
Constants are tracked through a bool. Copies are tracked by initializing

tcg/optimize: optimize temps tracking
The tcg_temp_info structure uses 24 bytes per temp. Now that we emulate
vector registers on most guests, it's not uncommon to have more than 100
used temps. This means we have initialize more than 2kB at least twice
per TB, often more when there is a few goto_tb.
Instead used a TCGTempSet bit array to track which temps are in used in
the current basic block. This means there are only around 16 bytes to
initialize.
This improves the boot time of a MIPS guest on an x86-64 host by around
7% and moves out tcg_optimize from the the top of the profiler list.

tcg/optimize: fix constant signedness
By convention, on a 64-bit host TCG internally stores 32-bit constants
as sign-extended. This is not the case in the optimizer when a 32-bit
constant is folded.
This doesn't seem to have more consequences than suboptimal code
generation. For instance the x86 backend assumes sign-extended constants,
and in some rare cases uses a 32-bit unsigned immediate 0xffffffff
instead of a 8-bit signed immediate 0xff for the constant -1. This is
with a ppc guest:

configure: Don't permit SDL or GTK on OSX
The cocoa GUI frontend assumes it is the only GUI (it redefines
main() so it always gets control before the rest of QEMU), so
it does not play well with other UIs like SDL or GTK. (Mostly
people building QEMU on OSX don't have the necessary dependencies
available for configure to build those other front ends, so
mostly this problem goes unnoticed.)
Make configure automatically disable the SDL and GTK front ends
if the cocoa front end is enabled. (We were sort of attempting
to do this for SDL before, but not in a way that worked very well.)

We don't include host-utils from qemu-common.h, to avoid dragging

This avoids having to manually swap them around when swapping to and

The VMStateDescription version changes, because the meaning of "shadow"

this, but I don't think it's worth the effort.

With these changes cpu_can_do_io boils down to a read of
cpu->can_do_io.

mirror: Fix coroutine reentrance
This fixes a regression introduced by commit dcfb3beb ("mirror: Do zero
write on target if sectors not allocated"), which was reported to cause
aborts with the message "Co-routine re-entered recursively".
The cause for this bug is the following code in mirror_iteration_done():
if (s->common.busy) {
qemu_coroutine_enter(s->common.co, NULL);
}
This has always been ugly because - unlike most places that reenter - it
doesn't have a specific yield that it pairs with, but is more
uncontrolled. What we really mean here is "reenter the coroutine if
it's in one of the four explicit yields in mirror.c".
This used to be equivalent with s->common.busy because neither
mirror_run() nor mirror_iteration() call any function that could yield.
However since commit dcfb3beb this doesn't hold true any more:
bdrv_get_block_status_above() can yield.
So what happens is that bdrv_get_block_status_above() wants to take a
lock that is already held, so it adds itself to the queue of waiting
coroutines and yields. Instead of being woken up by the unlock function,
however, it gets woken up by mirror_iteration_done(), which is obviously
wrong.
In most cases the code actually happens to cope fairly well with such
cases, but in this specific case, the unlock must already have scheduled
the coroutine for wakeup when mirror_iteration_done() reentered it. And
then the coroutine happened to process the scheduled restarts and tried
to reenter itself recursively.
This patch fixes the problem by pairing the reenter in
mirror_iteration_done() with specific yields instead of abusing
s->common.busy.

hw/pci-host/bonito: Avoid buffer overrun for bad LDMA/COP accesses
The LDMA and COP memory regions represent four 32 bit registers
each, but the memory regions themselves are 0x100 bytes large.
Add guards to the read and write accessors so that bogus accesses
beyond the four defined registers don't just run off the end of
the bonldma and boncop structs and into whatever lies beyond.

target-mips: simplify LWL/LDL mask generation
The LWL/LDL instructions mask the GPR with a mask depending on the
address alignement. It is currently computed by doing:
mask = 0x7fffffffffffffffull >> (t1 ^ 63)
It's simpler to generate it by doing:
mask = ~(-1 << t1)
It uses one TCG instruction less, and it avoids a 32/64-bit constant
loading which can take a few instructions on RISC hosts.

pci: allow 0 address for PCI IO/MEM regions
Some kernels program a 0 address for io regions. PCI 3.0 spec
section 6.2.5.1 doesn't seem to disallow this.
based on patch by Michael Roth <mdroth@linux.vnet.ibm.com>
Add pci_allow_0_addr in MachineClass to conditionally
allow addr 0 for pseries, as this can break other architectures.
This patch allows to hotplug PCI card in pseries machine, as the first
added card BAR0 is always set to 0 address.
This as a temporary hack, waiting to fix PCI memory priorities for more
machine types...

pc: Use PC_COMPAT_* for CPUID feature compatibility
Now we can use compat_props to keep CPUID feature compatibility, using
the boolean QOM properties for CPUID feature flags.
This simplifies the compatibility code, and reduces duplication between
pc_piix.c and pc_q35.c.

piix: Document coreboot-specific RAM size config register
The existing i440fx initialization code sets a PCI config register that
isn't documented anywhere in the Intel 440FX datasheet. Register 0x57 is
DRAMC (DRAM Control) and has nothing to do with the RAM size.
This was implemented in commit ec5f92ce6ac8ec09056be77e03c941be188648fa
because old coreboot code tried to read registers 0x5a-0x5f,0x56,0x57 to
get the RAM size from QEMU, but I couldn't find out why coreboot did
that. I assume it was a mistake, and the original code was supposed to
be reading the DRB[0-7] registers (offsets 0x60-0x67).
Document that coreboot-specific register offset in a macro and a
comment, for future reference.

make: load only required dependency files.
The old rules.mak loads dependency .d files using include directive
with file glob pattern "*.d". This breaks the build when build tree has
left-over *.d files from another build.
This patch fixes this by
- loading precise list of .d files made from *.o and *.mo.
- specifying explicit list of required dependency info files for
*.hex autogenerated sources.
Note that Makefile still includes some .d in root directory by including
"*.d".

make: fix where dependency *.d are stored.
In rules like "bar/%.o: %.c" there is a difference between $(*D) and
$(@D). $(*D) expands to '.', while $(@D) expands to 'bar'. It is
cleaner to generate *.d in the same directory where appropriate *.o
resides. This allows precise including of dependency info from .d files.
As a hack, we also touch two sources for generated *.hex files. Without
this hack, anyone doing "git pull; make" will not get *.hex rebuilt
correctly since the dependency file would be missing.

i.MX: Fix UART driver to work with unitialized "chardev" device
The "chardev" property initialization might have failed (for example because
there are not enough chardevs provided by QEMU).
The serial device emulator needs to be able to work with an uninitialized
(NULL) chardev device pointer.
This patch adds some missing tests on the chr pointer value before
using it.

Wire up the secure timer interrupt. Since we've defined

we now have four of them and the code is the same for each.

target-arm: Add AArch32 banked register access to secure physical timer
If EL3 is AArch32, then the secure physical timer is accessed via
banking of the registers used for the non-secure physical timer.
Implement this banking.
Note that the access controls for the AArch32 banked registers
remain the same as the physical-timer checks; they are not the
same as the controls on the AArch64 secure timer registers.

target-arm: Add debug check for mismatched cpreg resets
It's easy to accidentally define two cpregs which both try
to reset the same underlying state field (for instance a
clash between an AArch64 EL3 definition and an AArch32
banked register definition). if the two definitions disagree
about the reset value then the result is dependent on which
one happened to be reached last in the hashtable enumeration.
Add a consistency check to detect and assert in these cases:
after reset, we run a second pass where we check that the
reset operation doesn't change the value of the register.

cpu-exec: Do not invalidate original TB in cpu_exec_nocache()
Instead of invalidating an original TB in cpu_exec_nocache()
prematurely, just save a link to it in the temporary generated TB. If
cpu_io_recompile() is raised subsequently from the temporary TB,
invalidate the original one as well. That allows reusing the original TB
each time cpu_exec_nocache() is called to handle expired instruction
counter in icount mode.

block/mirror: limit qiov to IOV_MAX elements
If mirror has more free buffers than IOV_MAX, preadv(2)/pwritev(2)
EINVAL failures may be encountered.
It is possible to trigger this by setting granularity to a low value
like 8192.
This patch stops appending chunks once IOV_MAX is reached.
The spurious EINVAL failure can be reproduced with a qcow2 image file
and the following QMP invocation:
qmp.command('drive-mirror', device='virtio0', target='/tmp/r7.s1',
granularity=8192, sync='full', mode='absolute-paths',
format='raw')
While the guest is running dd if=/dev/zero of=/var/tmp/foo oflag=direct
bs=4k.

block: don't register quorum driver if SHA256 support is unavailable
Commit 488981a4 [block: convert quorum blockdrv to use crypto APIs]
broke qemu-iotest 041 on hosts with GnuTLS < 2.10.0. It converted a
compile-time check to a run-time check at device open time. The result
is that we now advertise a feature (the quorum block driver) that will
never work (on those hosts). There's no way (short of parsing
human-readable error messages) for qemu-iotests or any other API
consumer to recognise that the quorum block driver isn't _actually_
available and shouldn't be used or tested.
Move the run-time check to bdrv_quorum_init() to avoid registering the
quorum block driver if we know it cannot work. This way API consumers
can recognise it's unavailable.

>From the global state section, we don't need runstate with Xen. Right now,
the way the Xen toolstack knows when QEMU is ready is when QEMU reach
"running" runstate.
The configuration section and the section footers are not going to be
present in previous version of QEMU with xenfv machine, so we skip them.
The Xen toolstack libxenlight does not specify a particular version of the
'pc' machine, so migration from older version of QEMU used by Xen to newer
one would break due to missing "configuration" section and section footers.

migration: Fix global state with Xen.
When doing migration via the QMP command xen_save_devices_state, the
current runstate is not store into the global state section. Also the
current runstate is not the one we want on the receiver side.
During migration, the Xen toolstack paused QEMU before save the devices
state. Also, the toolstack expect QEMU to autostart when the migration is
finished.
So this patch store "running" as it's current runstate.

rtl8139: skip offload on short Ethernet/IP header (CVE-2015-5165)
Transmit offload features access Ethernet and IP headers the packet. If
the packet is too short we must not attempt to access header fields:
int proto = be16_to_cpu(*(uint16_t *)(saved_buffer + 12));
...
eth_payload_data = saved_buffer + ETH_HLEN;
...
ip = (ip_header*)eth_payload_data;

rtl8139: drop tautologous if (ip) {...} statement (CVE-2015-5165)
The previous patch stopped using the ip pointer as an indicator that the
IP header is present. When we reach the if (ip) {...} statement we know
ip is always non-NULL.
Remove the if statement to reduce nesting.

rtl8139: avoid nested ifs in IP header parsing (CVE-2015-5165)
Transmit offload needs to parse packet headers. If header fields have
unexpected values the offload processing is skipped.
The code currently uses nested ifs because there is relatively little
input validation. The next patches will add missing input validation
and a goto label is more appropriate to avoid deep if statement nesting.

tcg/mips: fix add2
The add2 code in the tcg_out_addsub2 function doesn't take into account
the case where rl == al == bl. In that case we can't compute the carry
after the addition. As it corresponds to a multiplication by 2, the
carry bit is the bit 31.
While this is a corner case, this prevents x86-64 guests to boot on a
MIPS host.

AioContext: force event loop iteration using BH
The notify_me optimization introduced in commit eabc97797310
("AioContext: fix broken ctx->dispatching optimization") skips
event_notifier_set() calls when the event loop thread is not blocked in
ppoll(2).
This optimization causes a deadlock if two aio_context_acquire() calls
race. notify_me = 0 during the race so the winning thread can enter
ppoll(2) unaware that the other thread is waiting its turn to acquire
the AioContext.
This patch forces ppoll(2) to return by scheduling a BH instead of
calling aio_notify().
The following deadlock with virtio-blk dataplane is fixed:
qemu ... -object iothread,id=iothread0 \
-drive if=none,id=drive0,file=test.img,... \
-device virtio-blk-pci,iothread=iothread0,drive=drive0
This command-line results in a hang early on without this patch.
Thanks to Paolo Bonzini <pbonzini@redhat.com> for investigating this bug
with me.

Let net_rx_packet() (which checks the same conditions) drops the packet

hw/net: handle flow control in mcf_fec driver receiver
The network mcf_fec driver emulated receive side method is not dealing
with network queue flow control properly.
Modify the receive side to check if we have enough space in the
descriptors to store the current packet. If not we process none of it
and return 0. When the guest frees up some buffers through its descriptors
we signal the qemu net layer to send more packets.

block/ssh: Avoid segfault if inet_connect doesn't set errno.
On some (but not all) systems:
$ qemu-img create -f qcow2 overlay -b ssh://xen/
Segmentation fault
It turns out this happens when inet_connect returns -1 in the
following code, but errno == 0.
s->sock = inet_connect(s->hostport, errp);
if (s->sock < 0) {
ret = -errno;
goto err;
}
In the test case above, no host called "xen" exists, so getaddrinfo fails.
On Fedora 22, getaddrinfo happens to set errno = ENOENT (although it
is *not* documented to do that), so it doesn't segfault.
On RHEL 7, errno is not set by the failing getaddrinfo, so ret =
-errno = 0, so the caller doesn't know there was an error and
continues with a half-initialized BDRVSSHState struct, and everything
goes south from there, eventually resulting in a segfault.
Fix this by setting ret to -EIO (same as block/nbd.c and
block/sheepdog.c). The real error is saved in the Error** errp
struct, so it is printed correctly:
$ ./qemu-img create -f qcow2 overlay -b ssh://xen/
qemu-img: overlay: address resolution failed for xen:22: No address associated with hostname

sheepdog: serialize requests to overwrapping area
Current sheepdog driver only serializes create requests in oid
unit. This mechanism isn't enough for handling requests to
overwrapping area spanning multiple oids, so it can result bugs like
below:
https://bugs.launchpad.net/sheepdog-project/+bug/1456421
This patch adds a new serialization mechanism for the problem. The
difference from the old one is:
1. serialize entire aiocb if their targetting areas overwrap
2. serialize all requests (read, write, and discard), not only creates
This patch also removes the old mechanism because the new one can be
an alternative.

memory: do not add a reference to the owner of aliased regions
Very often the owner of the aliased region is the same as the owner of the alias
region itself. When this happens, the reference count can never go back to 0 and
the owner is leaked. This is for example breaking hot-unplug of virtio-pci
devices (the device cannot be plugged back again with the same id).
Another common use for alias is to transform the system I/O address space
into an MMIO regions; in this case the aliased region never dies, so there
is no problem. Otherwise the owner is always the same for aliasing
and aliased region.
I checked all calls to memory_region_init_alias introduced after commit
dfde4e6 (memory: add ref/unref calls, 2013-05-06) and they do not need the
reference in order to keep the owner of the aliased region alive.

megasas: Add write function to handle write access to PCI BAR 3
This patch fixes a QEMU SEGFAULT when a write operation is performed on
the memory region of the PCI BAR 3 (base address space).
When a writeb(0xe0000000) is performed the .write function is invoked to
handle the write access, however, since the .write is not initialised,
the call to 0, causes QEMU to SEGFAULT.

main-loop: fix qemu_notify_event for aio_notify optimization
aio_notify can be optimized away, and in fact almost always will. However,
qemu_notify_event is used in places where this is incorrect---most notably,
when handling SIGTERM. When aio_notify is optimized away, it is possible that
QEMU enters a blocking ppoll immediately afterwards and stays there, without
reaching main_loop_should_exit().
Fix this by using a bottom half. The bottom half can be optimized too, but
scheduling it is enough for the ppoll not to block. The hang is thus avoided.

block: vpc - prevent overflow if max_table_entries >= 0x40000000
When we allocate the pagetable based on max_table_entries, we multiply
the max table entry value by 4 to accomodate a table of 32-bit integers.
However, max_table_entries is a uint32_t, and the VPC driver accepts
ranges for that entry over 0x40000000. So during this allocation:
s->pagetable = qemu_try_blockalign(bs->file, s->max_table_entries * 4);
The size arg overflows, allocating significantly less memory than
expected.
Since qemu_try_blockalign() size argument is size_t, cast the
multiplication correctly to prevent overflow.
The value of "max_table_entries * 4" is used elsewhere in the code as
well, so store the correct value for use in all those cases.
We also check the Max Tables Entries value, to make sure that it is <
SIZE_MAX / 4, so we know the pagetable size will fit in size_t.

virtio-blk: only clear VIRTIO_F_ANY_LAYOUT for legacy device
Chapter 6.3 of spec said
"
Transitional devices MUST offer, and if offered by the device
transitional drivers MUST accept the following:
VIRTIO_F_ANY_LAYOUT (27)
"
So this patch only clear VIRTIO_F_LAYOUT for legacy device.

axienet: Flush queued packets when rx is done
eth_can_rx checks s->rxsize and returns false if it is non-zero. Because
of the .can_receive semantics change, this will make the incoming queue
disabled by peer, until it is explicitly flushed. So we should flush it
when s->rxsize is becoming zero.
Squash eth_can_rx semantics into etx_rx and drop .can_receive()
callback, also add flush when rx buffer becomes available again after a
packet gets queued.
The other conditions, "!axienet_rx_resetting(s) &&
axienet_rx_enabled(s)" are OK because enet_write already calls
qemu_flush_queued_packets when the register bits are changed.

hw/net: add simple phy support to mcf_fec driver
The Linux fec driver needs at least basic phy support to probe and work.
The current qemu mcf_fec emulation has no support for the reading or
writing of the MDIO lines to access an attached phy.
This code adds a very simple set of register results for a fixed phy
setup - very similar to that used on an m5208evb board. This is enough
to probe and identify an emulated attached phy.

The current unit test only verifies the encryption API,

later discovered & fixed by commit bd09594, thanks to the
QEMU I/O tests for qcow2 encryption, but we should really
detect this directly in the crypto unit tests. Also remove

ide: Clear DRQ after handling all expected accesses
This is additional hardening against an end_transfer_func that fails to
clear the DRQ status bit. The bit must be unset as soon as the PIO
transfer has completed, so it's better to do this in a central place
instead of duplicating the code in all commands (and forgetting it in
some).

ide: Check array bounds before writing to io_buffer (CVE-2015-5154)
If the end_transfer_func of a command is called because enough data has
been read or written for the current PIO transfer, and it fails to
correctly call the command completion functions, the DRQ bit in the
status register and s->end_transfer_func may remain set. This allows the
guest to access further bytes in s->io_buffer beyond s->data_end, and
eventually overflowing the io_buffer.
One case where this currently happens is emulation of the ATAPI command
START STOP UNIT.
This patch fixes the problem by adding explicit array bounds checks
before accessing the buffer instead of relying on end_transfer_func to
function correctly.

framebuffer: set DIRTY_MEMORY_VGA on RAM that is used for the framebuffer
The MemoryRegionSection contains enough information to access the
RAM region underlying the framebuffer, and can be cached inside the
display device.
By doing this, the new framebuffer_update_memory_section function can
enable dirty memory logging on the relevant RAM region. The function
must be called whenever the stride or base of the framebuffer changes;
a simple way to cover these cases is to call it on every full frame
invalidation, which is a rare case.
framebuffer_update_display now works entirely on a MemoryRegionSection,
without going through cpu_physical_memory_map/unmap.

scsi: Handle no media case for scsi_get_configuration
Currently, scsi_get_configuration always returns a current
profile (DVD or CD), even when there is actually no media present.
By comparison, ide/atapi uses a default profile of 0 (MMC_PROFILE_NONE)
for this case and checks for tray_open, so let's do the same for scsi.
This fixes a problem I'm seeing with Fedora 22 guests where systemd
cdrom_id fails to unmount after a QEMU-initiated eject against a
scsi cdrom device because it believes the media is still present
(but unreadable).

qemu-char: Fix missed data on unix socket
Commit 812c1057 introduced HUP detection on unix and tcp sockets prior
to a read in tcp_chr_read. This unfortunately broke CloudStack 4.2
which relied on the old behaviour where data on a socket was readable
even if a HUP was present.
A working solution is to properly check the return values from recv,
handling a closed socket once there is no more data to read.
Also enable polling for G_IO_NVAL to ensure the callback is called
for all possible events as these should now be possible to handle
with the improved error detection.

vfio/pci: Fix RTL8168 NIC quirks
The RTL8168 quirk correctly describes using bit 31 as a signal to
mark a latch/completion, but the code mistakenly uses bit 28. This
causes the Realtek driver to spin on this register for quite a while,
20k cycles on Windows 7 v7.092 driver. Then it gets frustrated and
tries to set the bit itself and spins for another 20k cycles. For
some this still results in a working driver, for others not. About
the only thing the code really does in its current form is protect
the guest from sneaking in writes to the real hardware MSI-X table.
The fix is obviously to use bit 31 as we document that we should.
The other problem doesn't seem to affect current drivers as nobody
seems to use these window registers for writes to the MSI-X table, but
we need to use the stored data when a write is triggered, not the
value of the current write, which only provides the offset.
Note that only the Windows drivers from Realtek seem to use these
registers, the Microsoft drivers provided with Windows 8.1 do not
access them, nor do Linux in-kernel drivers.

The new spice-server function to limit the number of monitors (0.12.6)
changed while development from spice_qxl_set_monitors_config_limit to
spice_qxl_max_monitors (accepted upstream).
By mistake I post patch with former name.

AioContext: optimize clearing the EventNotifier
It is pretty rare for aio_notify to actually set the EventNotifier. It
can happen with worker threads such as thread-pool.c's, but otherwise it
should never be set thanks to the ctx->notify_me optimization. The
previous patch, unfortunately, added an unconditional call to
event_notifier_test_and_clear; now add a userspace fast path that
avoids the call.
Note that it is not possible to do the same with event_notifier_set;
it would break, as proved (again) by the included formal model.
This patch survived over 3000 reboots on aarch64 KVM.

AioContext: fix broken placement of event_notifier_test_and_clear
event_notifier_test_and_clear must be called before processing events.
Otherwise, an aio_poll could "eat" the notification before the main
I/O thread invokes ppoll(). The main I/O thread then never wakes up.
This is an example of what could happen:
i/o thread vcpu thread worker thread
---------------------------------------------------------------------
lock_iothread
notify_me = 1
...
unlock_iothread
bh->scheduled = 1
event_notifier_set
lock_iothread
notify_me = 3
ppoll
notify_me = 1
aio_dispatch
aio_bh_poll
thread_pool_completion_bh
bh->scheduled = 1
event_notifier_set
node->io_read(node->opaque)
event_notifier_test_and_clear
ppoll
*** hang ***
"Tracing" with qemu_clock_get_ns shows pretty much the same behavior as
in the previous bug, so there are no new tricks here---just stare more
at the code until it is apparent.
One could also use a formal model, of course. The included one shows
this with three processes: notifier corresponds to a QEMU thread pool
worker, temporary_waiter to a VCPU thread that invokes aio_poll(),
waiter to the main I/O thread. I would be happy to say that the
formal model found the bug for me, but actually I wrote it after the
fact.
This patch is a bit of a big hammer. The next one optimizes it,
with help (this time for real rather than a posteriori :)) from
another, similar formal model.

AioContext: fix broken ctx->dispatching optimization
This patch rewrites the ctx->dispatching optimization, which was the cause
of some mysterious hangs that could be reproduced on aarch64 KVM only.
The hangs were indirectly caused by aio_poll() and in particular by
flash memory updates's call to blk_write(), which invokes aio_poll().
Fun stuff: they had an extremely short race window, so much that
adding all kind of tracing to either the kernel or QEMU made it
go away (a single printf made it half as reproducible).
On the plus side, the failure mode (a hang until the next keypress)
made it very easy to examine the state of the process with a debugger.
And there was a very nice reproducer from Laszlo, which failed pretty
often (more than half of the time) on any version of QEMU with a non-debug
kernel; it also failed fast, while still in the firmware. So, it could
have been worse.
For some unknown reason they happened only with virtio-scsi, but
that's not important. It's more interesting that they disappeared with
io=native, making thread-pool.c a likely suspect for where the bug arose.
thread-pool.c is also one of the few places which use bottom halves
across threads, by the way.
I hope that no other similar bugs exist, but just in case :) I am
going to describe how the successful debugging went... Since the
likely culprit was the ctx->dispatching optimization, which mostly
affects bottom halves, the first observation was that there are two
qemu_bh_schedule() invocations in the thread pool: the one in the aio
worker and the one in thread_pool_completion_bh. The latter always
causes the optimization to trigger, the former may or may not. In
order to restrict the possibilities, I introduced new functions
qemu_bh_schedule_slow() and qemu_bh_schedule_fast():
/* qemu_bh_schedule_slow: */
ctx = bh->ctx;
bh->idle = 0;
if (atomic_xchg(&bh->scheduled, 1) == 0) {
event_notifier_set(&ctx->notifier);
}
/* qemu_bh_schedule_fast: */
ctx = bh->ctx;
bh->idle = 0;
assert(ctx->dispatching);
atomic_xchg(&bh->scheduled, 1);
Notice how the atomic_xchg is still in qemu_bh_schedule_slow(). This
was already debated a few months ago, so I assumed it to be correct.
In retrospect this was a very good idea, as you'll see later.
Changing thread_pool_completion_bh() to qemu_bh_schedule_fast() didn't
trigger the assertion (as expected). Changing the worker's invocation
to qemu_bh_schedule_slow() didn't hide the bug (another assumption
which luckily held). This already limited heavily the amount of
interaction between the threads, hinting that the problematic events
must have triggered around thread_pool_completion_bh().
As mentioned early, invoking a debugger to examine the state of a
hung process was pretty easy; the iothread was always waiting on a
poll(..., -1) system call. Infinite timeouts are much rarer on x86,
and this could be the reason why the bug was never observed there.
With the buggy sequence more or less resolved to an interaction between
thread_pool_completion_bh() and poll(..., -1), my "tracing" strategy was
to just add a few qemu_clock_get_ns(QEMU_CLOCK_REALTIME) calls, hoping
that the ordering of aio_ctx_prepare(), aio_ctx_dispatch, poll() and
qemu_bh_schedule_fast() would provide some hint. The output was:
(gdb) p last_prepare
$3 = 103885451
(gdb) p last_dispatch
$4 = 103876492
(gdb) p last_poll
$5 = 115909333
(gdb) p last_schedule
$6 = 115925212
Notice how the last call to qemu_poll_ns() came after aio_ctx_dispatch().
This makes little sense unless there is an aio_poll() call involved,
and indeed with a slightly different instrumentation you can see that
there is one:
(gdb) p last_prepare
$3 = 107569679
(gdb) p last_dispatch
$4 = 107561600
(gdb) p last_aio_poll
$5 = 110671400
(gdb) p last_schedule
$6 = 110698917
So the scenario becomes clearer:
iothread VCPU thread
--------------------------------------------------------------------------
aio_ctx_prepare
aio_ctx_check
qemu_poll_ns(timeout=-1)
aio_poll
aio_dispatch
thread_pool_completion_bh
qemu_bh_schedule()
At this point bh->scheduled = 1 and the iothread has not been woken up.
The solution must be close, but this alone should not be a problem,
because the bottom half is only rescheduled to account for rare situations
(see commit 3c80ca1, thread-pool: avoid deadlock in nested aio_poll()
calls, 2014-07-15).
Introducing a third thread---a thread pool worker thread, which
also does qemu_bh_schedule()---does bring out the problematic case.
The third thread must be awakened *after* the callback is complete and
thread_pool_completion_bh has redone the whole loop, explaining the
short race window. And then this is what happens:
thread pool worker
--------------------------------------------------------------------------
<I/O completes>
qemu_bh_schedule()
Tada, bh->scheduled is already 1, so qemu_bh_schedule() does nothing
and the iothread is never woken up. This is where the bh->scheduled
optimization comes into play---it is correct, but removing it would
have masked the bug.
So, what is the bug?
Well, the question asked by the ctx->dispatching optimization ("is any
active aio_poll dispatching?") was wrong. The right question to ask
instead is "is any active aio_poll *not* dispatching", i.e. in the prepare
or poll phases? In that case, the aio_poll is sleeping or might go to
sleep anytime soon, and the EventNotifier must be invoked to wake
it up.
In any other case (including if there is *no* active aio_poll at all!)
we can just wait for the next prepare phase to pick up the event (e.g. a
bottom half); the prepare phase will avoid the blocking and service the
bottom half.
Expressing the invariant with a logic formula, the broken one looked like:
!(exists(thread): in_dispatching(thread)) => !optimize
or equivalently:
!(exists(thread):
in_aio_poll(thread) && in_dispatching(thread)) => !optimize
In the correct one, the negation is in a slightly different place:
(exists(thread):
in_aio_poll(thread) && !in_dispatching(thread)) => !optimize
or equivalently:
(exists(thread): in_prepare_or_poll(thread)) => !optimize
Even if the difference boils down to moving an exclamation mark :)
the implementation is quite different. However, I think the new
one is simpler to understand.
In the old implementation, the "exists" was implemented with a boolean
value. This didn't really support well the case of multiple concurrent
event loops, but I thought that this was okay: aio_poll holds the
AioContext lock so there cannot be concurrent aio_poll invocations, and
I was just considering nested event loops. However, aio_poll _could_
indeed be concurrent with the GSource. This is why I came up with the
wrong invariant.
In the new implementation, "exists" is computed simply by counting how many
threads are in the prepare or poll phases. There are some interesting
points to consider, but the gist of the idea remains:
1) AioContext can be used through GSource as well; as mentioned in the
patch, bit 0 of the counter is reserved for the GSource.
2) the counter need not be updated for a non-blocking aio_poll, because
it won't sleep forever anyway. This is just a matter of checking
the "blocking" variable. This requires some changes to the win32
implementation, but is otherwise not too complicated.
3) as mentioned above, the new implementation will not call aio_notify
when there is *no* active aio_poll at all. The tests have to be
adjusted for this change. The calls to aio_notify in async.c are fine;
they only want to kick aio_poll out of a blocking wait, but need not
do anything if aio_poll is not running.
4) nested aio_poll: these just work with the new implementation; when
a nested event loop is invoked, the outer event loop is never in the
prepare or poll phases. The outer event loop thus has already decremented
the counter.

aio-win32: reorganize polling loop
Preparatory bugfixes and tweaks to the loop before the next patch:
- disable dispatch optimization during aio_prepare. This fixes a bug.
- do not modify "blocking" until after the first WaitForMultipleObjects
call. This is needed in the next patch.
- change the loop to do...while. This makes it obvious that the loop
is always entered at least once. In the next patch this is important
because the first iteration undoes the ctx->notify_me increment that
happened before entering the loop.

tests: remove irrelevant assertions from test-aio
In these tests, the purpose of the initial calls to aio_poll and
g_main_context_iteration is simply to put the AioContext in a
known state; the return value of the function does not really

the assertions to a while loop which expresses the intention

net: Flush queued packets when guest resumes
Since commit 6e99c63 "net/socket: Drop net_socket_can_send" and friends,
net queues need to be explicitly flushed after qemu_can_send_packet()
returns false, because the netdev side will disable the polling of fd.
This fixes the case of "cont" after "stop" (or migration).

net/vmxnet3: Fix RX TCP/UDP checksum on partially summed packets
Convert partially summed packets to be fully checksummed.
In case csum offloaded packet, vmxnet3 implementation always passes an
RxCompDesc with the "Checksum calculated and found correct" notification
to the OS. This emulates the observed ESXi behavior.
Therefore, if packet has the NEEDS_CSUM bit set, we must calculate and
place a fully computed checksum into the tcp/udp header. Otherwise, the
OS driver will receive a checksum-correct indication but with the actual
tcp/udp checksum field having just the pseudo header csum value.
If host OS performs forwarding, it will forward an incorrectly
checksummed packet.

This patch adds another short PRDT test case where the first sector can

sectors. This exercises a different code path in ide_dma_cb().

NANOSECONDS_PER_SECOND to NSEC_PER_SEC.
On Mac OS X there is a <dispatch/time.h> system header which also
defines NSEC_PER_SEC. This causes compiler warnings.
Let's use the old name instead. It's longer but it doesn't clash.

virtio-net: Flush incoming queues when DRIVER_OK is being set
This patch fixes network hang after "stop" then "cont", while network
packets keep arriving.
Tested both manually (tap, host pinging guest) and with Jason's qtest
series (plus his "[PATCH 2.4] socket: pass correct size in
net_socket_send()" fix).
As virtio_net_set_status is called when guest driver is setting status
byte and when vm state is changing, it is a good opportunity to flush
queued packets.
This is necessary because during vm stop the backend (e.g. tap) would
stop rx processing after .can_receive returns false, until the queue is
explicitly flushed or purged.
The other interesting condition in .can_receive, virtio_queue_ready(),
is handled by virtio_net_handle_rx() when guest kicks; the 3rd condition
is invalid queue index which doesn't need flushing.

crypto: avoid undefined behavior in nettle calls
Calling a function pointer that was cast from an incompatible function
results in undefined behavior. 'void *' isn't compatible with 'struct
XXX *', so we can't cast to nettle_cipher_func, but have to provide a
wrapper. (Conversion from 'void *' to 'struct XXX *' might require
computation, which won't be done if we drop argument's true type, and
pointers can have different sizes so passing arguments on stack would
bug.)
Having two different prototypes based on nettle version doesn't make
this solution any nicer.

memory: fix refcount leak in memory_region_present
memory_region_present() leaks a reference to a MemoryRegion in the
case "mr == container". While fixing it, avoid reference counting
altogether for memory_region_present(), by using RCU only.
The return value could in principle be already invalid immediately
after memory_region_present returns, but presumably the caller knows
that and it's using memory_region_present to probe for devices that
are unpluggable, or something like that. The RCU critical section
is needed anyway, because it protects as->current_map.

qxl driver is not limited on any kind on head use so can decide to use

target-i386: emulate CPUID level of real hardware
W10 insider has a bug where it ignores CPUID level and interprets
CPUID.(EAX=07H, ECX=0H) incorrectly, because CPUID in fact returned
CPUID.(EAX=04H, ECX=0H); this resulted in execution of unsupported
instructions.
While it's a Windows bug, there is no reason to emulate incorrect level.
I used http://instlatx64.atw.hu/ as a source of CPUID and checked that
it matches Penryn Xeon X5472, Westmere Xeon W3520, SandyBridge i5-2540M,
and Haswell i5-4670T.
kvm64 and qemu64 were bumped to 0xD to allow all available features for
them (and to avoid the same Windows bug).

hw/arm/boot: Increase fdt alignment
The Linux kernel on aarch64 creates a page table entry at early bootup
that spans the 2MB range on memory spanning the fdt start address:
[ ALIGN_DOWN(fdt, 2MB) ... ALIGN_DOWN(fdt, 2MB) + 2MB ]
This means that when our current 4k alignment happens to fall at the end
of the aligned region, Linux tries to access memory that is not mapped.
The easy fix is to instead increase the alignment to 2MB, making Linux's
logic always succeed.
We leave the existing 4k alignment for 32bit kernels to not cause any
regressions due to space constraints.

target-arm: Fix broken SCTLR_EL3 reset
The SCTLR_EL3 cpreg definition was implicitly resetting the
register state to 0, which is both wrong and clashes with
the reset done via the SCTLR definition (since sctlr[3]
is unioned with sctlr_s). This went unnoticed until recently,
when an unrelated change (commit a903c449b41f105aa) happened to
perturb the order of enumeration through the cpregs hashtable for
reset such that the erroneous reset happened after the correct one
rather than before it. Fix this by marking SCTLR_EL3 as an alias,
so its reset is left up to the AArch32 view.

target-mips: fix page fault address for LWL/LWR/LDL/LDR
When a LWL, LWR, LDL or LDR instruction triggers a page fault, QEMU
currently reports the aligned address in CP0 BadVAddr, while the Windows
NT kernel expects the unaligned address.
This patch adds a byte access with the unaligned address at the
beginning of the LWL/LWR/LDL/LDR instructions to possibly trigger a page
fault and fill the QEMU TLB.

linux-user: Fix MIPS N64 trap and break instruction bug
For the MIPS N64 ABI when QEMU reads the break/trap instruction so that
it can inspect the break/trap code it reads 8 rather than 4 bytes
which means it finds the code field from the instruction after the
break/trap instruction. This then causes the break/trap handling
code to fail because it does not understand the code number.
The fix forces QEMU to always read 4 bytes of instruction data rather
than deciding how much to read based on the ABI.

migration: We also want to store the global state for savevm
Commit df4b1024526cae3479da3492d6371fd4a7324a03 introduced global_state
section. But it only filled the state while doing migration. While
doing a savevm, we stored an empty string as state. So when we did a
loadvm, it complained that state was invalid.

block/curl: Don't lose original error when a connection fails.
Currently if qemu is connected to a curl source (eg. web server), and
the web server fails / times out / dies, you always see a bogus EIO
"Input/output error".
For example, choose a large file located on any local webserver which
you control:
$ qemu-img convert -p http://example.com/large.iso /tmp/test
Once it starts copying the file, stop the webserver and you will see
qemu-img fail with:
qemu-img: error while reading sector 61440: Input/output error
This patch does two things: Firstly print the actual error from curl
so it doesn't get lost. Secondly, change EIO to EPROTO. EPROTO is a
POSIX.1 compatible errno which more accurately reflects that there was
a protocol error, rather than some kind of hardware failure.
After this patch is applied, the error changes to:
$ qemu-img convert -p http://example.com/large.iso /tmp/test
qemu-img: curl: transfer closed with 469989 bytes remaining to read
qemu-img: error while reading sector 16384: Protocol error

Draining is not necessary, I/O can happen as soon as the

reopening the file for read/write, or while modifying the
backing file chain, but that is done separately in
bdrv_reopen_multiple or bdrv_close; this particular
bdrv_drain_all does nothing for that.

watchdog/diag288: correctly register for system reset requests
The diag288 watchdog is no sysbus device, therefore it doesn't get
triggered on resets automatically using dc->reset.
Let's register the reset handler manually, so we get correctly notified
again when a system reset was requested. Also reset the watchdog on
subsystem resets that don't trigger a full system reset.

rbd: make qemu's cache setting override any ceph setting
To be safe, when cache=none is used ceph settings should not be able
to override it to turn on caching. This was previously possible with
rbd_cache=true in the rbd device configuration or a ceph configuration
file. Similarly, rbd settings could have turned off caching when qemu
requested it, although this would just be a performance problem.
Fix this by changing rbd's cache setting to match qemu after all other
ceph settings have been applied.

block: Fix backing file child when modifying graph
This patch moves bdrv_attach_child() from the individual places that add
a backing file to a BDS to bdrv_set_backing_hd(), which is called by all
of them. It also adds bdrv_detach_child() there.
For normal operation (starting with one backing file chain and not
changing it until the topmost image is closed) and live snapshots, this
constitutes no change in behaviour.
For all other cases, this is a fix for the bug that the old backing file
was still referenced as a child, and the new one wasn't referenced.

It is the same as bdrv_open_image(), except that it doesn't only return

As the BdrvChild object already contains a BlockDriverState pointer (and
this is supposed to become the only pointer so that bdrv_append() and
friends can just change a single pointer in BdrvChild), the pbs
parameter is removed for bdrv_open_child().

pc: fix reuse of pc-i440fx-2.4 in pc-i440fx-2.3
commit fddd179ab962f6f78a8493742e1068d6a620e059,
"pc: Convert *_MACHINE_OPTIONS macros into functions"
broke the chaining of *_machine_options() functions on
pc-i440fx-2.3, at:
-#define PC_I440FX_2_3_MACHINE_OPTIONS \
- PC_I440FX_2_4_MACHINE_OPTIONS, \
- .alias = NULL, \
- .is_default = 0
+static void pc_i440fx_2_3_machine_options(QEMUMachine *m)
+{
+ pc_i440fx_machine_options(m);
+ m->alias = NULL;
+ m->is_default = 0;
+}
I have replaced PC_I440FX_2_4_MACHINE_OPTIONS with a
pc_i440fx_machine_options() call, instead of calling
pc_i440fx_2_4_machine_options(). This broke the setting of default_machine_opts
and default_display on pc-i440fx-{2.0,2,1,2.2,2.3}.
Fix this by making pc_i440fx_2_3_machine_options() reuse
pc_i440fx_2_4_machine_options().

Revert "virtio-net: enable virtio 1.0"
This reverts commit df91055db5c9cee93d70ca8c08d72119a240b987.
This is because:
- vhost support virtio 1.0 now
- transport code (e.g virtio-pci) set this feature when modern is
enabled, setting this unconditionally will break disable-modern=on.

tci: Fix compile failure by including qemu-common.h
Compilation of TCI was accidentally broken by the recent disassembler
changes:
CC x86_64-softmmu/arch_init.o
In file included from target-i386/cpu-qom.h:23:0,
from target-i386/cpu.h:986,
from include/qemu-common.h:122,
from include/disas/bfd.h:12,
from disas/tci.c:20:
include/qom/cpu.h:178:43: error: unknown type name ‘disassemble_info’
void (*disas_set_info)(CPUState *cpu, disassemble_info *info);
^
include/qom/cpu.h:179:1: error:
no semicolon at end of struct or union [-Werror]
} CPUClass;
^
cc1: all warnings being treated as errors
The underlying cause of this is an include loop:
bfd.h -> qemu-common.h -> target-arm/cpu.h -> target-arm/cpu-qom.h
-> qom/cpu.h -> bfd.h
which means that if bfd.h is included first then qom/cpu.h doesn't
get the definition of the disassemble_info type that it wanted.
The easiest fix for this is to include qemu-common.h from tci.c
before including disas/bfd.h.

disas: cris: Fix 0 buffer length case
Cris has the complication of variable length instructions and has
a check in place to clamp memory reads in case the disas request
doesn't have enough bytes for the instruction being disas'd. This
breaks down in the case where disassembling for the monitor where
the buffer length is defaulted to 0.
The buffer length should never be zero for a regular target_disas,
so we can safely assume the 0 case is for the monitor in which case
consider the buffer length to be the max for cris instructions.

disas: arm: QOMify target specific disas setup
Move the target_disas() ARM specifics to the QOM disas_set_info hook
and delete the ARM specific code in disas.c.
This has the extra advantage of the more fully featured target_disas()
implementation now applying to monitor_disas().
Currently, target_disas() has multi-endian, thumb and AArch64
support whereas the existing monitor_disas() support only has vanilla
AA32 support.
E.G. Running an AA64 linux kernel the following -d in_asm disas happens
(taget_disas()):

Also add corresponding cpu_exec_exit() call from unrealize.
cpu_dt_id assignment from instance_init is no longer needed since
correct assignment for cpu_dt_id is already present in realizefn.

[AF: Keep calling cpu_exec_init() for CONFIG_USER_ONLY]
Signed-off-by: Andreas Färber <afaerber@suse.de>
commit b7bca7333411bd19c449147e8202ae6b0e4a8e09
Author: Bharata B Rao <bharata@linux.vnet.ibm.com>
Date: Tue Jun 23 19:31:13 2015 -0700
cpu: Convert cpu_index into a bitmap
Currently CPUState::cpu_index is monotonically increasing and a newly
created CPU always gets the next higher index. The next available
index is calculated by counting the existing number of CPUs. This is
fine as long as we only add CPUs, but there are architectures which
are starting to support CPU removal, too. For an architecture like PowerPC
which derives its CPU identifier (device tree ID) from cpu_index, the
existing logic of generating cpu_index values causes problems.
With the currently proposed method of handling vCPU removal by parking
the vCPU fd in QEMU
(Ref: http://lists.gnu.org/archive/html/qemu-devel/2015-02/msg02604.html),
generating cpu_index this way will not work for PowerPC.
This patch changes the way cpu_index is handed out by maintaining
a bit map of the CPUs that tracks both addition and removal of CPUs.
The CPU bitmap allocation logic is part of cpu_exec_init(), which is
called by instance_init routines of various CPU targets. Newly added
cpu_exec_exit() API handles the deallocation part and this routine is
called from generic CPU instance_finalize.
Note: This new CPU enumeration is for !CONFIG_USER_ONLY only.
CONFIG_USER_ONLY continues to have the old enumeration logic.

cpu: Add Error argument to cpu_exec_init()
Add an Error argument to cpu_exec_init() to let users collect the
error. This is in preparation to change the CPU enumeration logic
in cpu_exec_init(). With the new enumeration logic, cpu_exec_init()
can fail if cpu_index values corresponding to max_cpus have already
been handed out.
Since all current callers of cpu_exec_init() are from instance_init,
use error_abort Error argument to abort in case of an error.

cpu: Reorder cpu->as, cpu->thread_id, cpu->memory_dispatch init
Instead of initializing cpu->as, cpu->thread_id, and reloading memory
map while holding cpu_list_lock(), do it earlier, before locking the CPU
list and initializing cpu_index.
This allows the code handling cpu_index and global CPU list to be
isolated from the rest.

mips/kvm: Sync with newer MIPS KVM headers
The KVM_REG_MIPS_COUNT_* definitions are now included in
linux-headers/asm-mips/kvm.h since commit b061808d39fa ("linux-headers:

in target-mips/kvm.c can now be dropped (the definitions were tweaked
slightly in commit 7a52ce8a1607 ("linux-headers: update") which
triggered the following build warnings turned errors):
target-mips/kvm.c:232:0: error: "KVM_REG_MIPS_COUNT_CTL" redefined [-Werror]

Commit 3972ef6f830d ("tcg: Push merged memop+mmu_idx parameter to

In file included from tcg/tcg.c:258:0:

It looks like lb was meant to refer to the TCGLabelQemuLdst *l

and byte-swaps it if target is BE and device is LE.
Use fixed-endian LE APIs instead.

Thanks to the last patch, pc_cmos_init() doesn't need the (optional)

pc_basic_device_init() not to hand it back to pc_init1() / pc_q35_init(),
and update the latter not to carry the FDC to pc_cmos_init(). This
simplifies the code.

hw/i386/pc: reflect any FDC @ ioport 0x3f0 in the CMOS
With the pc-q35-2.4 machine type, if the user creates an ISA FDC manually:
-device isa-fdc,driveA=drive-fdc0-0-0 \
-drive file=...,if=none,id=drive-fdc0-0-0,format=raw
then the board-default FDC will be skipped, and only the explicitly
requested FDC will exist. qtree-wise, this is correct; however such an FDC
is currently not registered in the CMOS, because that code is only reached
for the board-default FDC.
The pc_cmos_init_late() one-shot reset handler -- one-shot because the
CMOS is not reprogrammed during warm reset -- should search for any ISA
FDC devices, created implicitly (by board code) or explicitly, and set the
CMOS accordingly to the ISA FDC(s) with iobase=0x3f0:
- if there is no such FDC, report both drives absent,
- if there is exactly one such FDC, report its drives in the CMOS,
- if there are more than one such FDCs, then pick one (it is not specified
which one), and print a warning about the ambiguity.

ich9: implement strap SPKR pin logic
If the signal is sampled high, this indicates that the system is
strapped to the "No Reboot" mode (ICH9 will disable the TCO Timer system
reboot feature). The status of this strap is readable via the NO_REBOOT
bit (CC: offset 0x3410:bit 5).
The NO_REBOOT bit is set when SPKR pin on ICH9 is sampled high. This bit
may be set or cleared by software if the strap is sampled low but may
not override the strap when it indicates "No Reboot".
This patch implements the logic where hardware has ability to set SPKR
pin through a property named "noreboot" and it's sampled high by
default.

qga: added GuestPCIAddress information
PCIAddress inforfation is obtained via SetupApi, which provides the
information about address, bus, etc. We look throught entire device tree
in the system and try to find device object for given volume. For this PDO
SetupDiGetDeviceRegistryProperty is called, which reads PCI configuration
for a given devicei if it is possible.
This is the most convinient way for a userspace service. The lookup is
performed for every volume available. However, this information is
not mandatory for vss-provider.
In order to use SetupApi we need to notify linker about it. We do not need
to install additional libs, so we do not make separate configuration
option to use libsetupapi.su
SetupApi gives as the same information as kernel driver
with IRP_MN_QUERY_INTERFACE.

Windows defines more bus types than Linux. Thus some values have been added

qga: added mountpoint and filesystem type for single volume
We should use GetVolumeXXX api to work with volumes. This will help us to
resolve the situation with volumes without drive letter, i.e. when the
volume is mounted as a folder. Such volume is called mounted folder.
This volume is a regular mounted volume from all other points of view.
The information about non mounted volume is reported as System Reserved.
This volume is not mounted and thus it is not writable.
GuestDiskAddressList API is not used because operations are performed with
volumes but no with disks. This means that spanned disk will
be counted and handled as a single volume. It is worth mentioning
that the information about every disk in the volume can be queried
via IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS.

qga: win32 qmp_guest_network_get_interfaces implementation
By default, IPv4 prefixes will be derived by matching the address

matched this way due to the unpredictable order of entries.
In Windows Vista/2008 guests and newer, both IPv4 and IPv6 prefixes
can be retrieved from OnLinkPrefixLength. Setting --extra-cflags
in the build configuration to "-D_WIN32_WINNT=0x600"
or greater makes OnLinkPrefixLength available. Setting --extra-cflags
is not required and if not set, the default approach to get the prefix
will be taken.

qga/qmp_guest_fstrim: Return per path fstrim result
The current guest-fstrim support only returns an error if some
mountpoint was unable to be trimmed, skipping any possible additional
mountpoints. The result of the TRIM operation itself is also discarded.
This change returns a per mountpoint result of the TRIM operation. If an
error occurs on some mountpoints that error is returned and the
guest-fstrim continue with any additional mountpoints.
The returned values for errors, minimum and trimmed are dependant on the
filesystem, storage stacks and kernel version.

qga/commands-posix: Fix bug in guest-fstrim
The FITRIM ioctl updates the fstrim_range structure it receives. This
way the caller can determine how many bytes were trimmed. The
guest-fstrim logic reuses the same fstrim_range for each filesystem,
effectively limiting each filesystem to trim at most as much as the
previous was able to trim.
If a previous filesystem would have trimmed 0 bytes, than the next
filesystem would report an error 'Invalid argument' because a FITRIM
request with length 0 is not valid.
This change resets the fstrim_range structure for each filesystem.

sPAPR: Clear stale MSIx table during EEH reset
The PCI device MSIx table is cleaned out in hardware after EEH PE
reset. However, we still hold the stale MSIx entries in QEMU, which
should be cleared accordingly. Otherwise, we will run into another
(recursive) EEH error and the PCI devices contained in the PE have
to be offlined exceptionally.
The patch introduces function spapr_phb_vfio_eeh_pre_reset(), which
is called by sPAPR when asserting hot or fundamental reset, to clear
stale MSIx table for VFIO PCI devices before EEH PE reset so that
MSIx table could be restored properly after EEH PE reset.

spapr_vty: lookup should only return valid VTY objects
If a guest passes the reg property of a valid VIO object that is not a VTY
to either H_GET_TERM_CHAR or H_PUT_TERM_CHAR, QEMU hits a dynamic cast
assertion and aborts.
PAPR+ says "Hypervisor checks the termno parameter for validity against the
Vterm IOA unit addresses assigned to the partition, else return H_Parameter."
This patch adds a type check to ensure vty_lookup() either returns a pointer
to a valid VTY object or NULL. H_GET_TERM_CHAR and H_PUT_TERM_CHAR will
now return H_PARAMETER to the guest instead of crashing.
The patch has no effect on the reg == 0 hack used to implement the RTAS call
display-character.

xics_kvm: Don't enable KVM_CAP_IRQ_XICS if already enabled
When supporting CPU hot removal by parking the vCPU fd and reusing
it during hotplug again, there can be cases where we try to reenable
KVM_CAP_IRQ_XICS CAP for the vCPU for which it was already enabled.
Introduce a boolean member in ICPState to track this and don't
reenable the CAP if it was already enabled earlier.
Re-enabling this CAP should ideally work, but currently it results in
kernel trying to create and associate ICP with this vCPU and that
fails since there is already an ICP associated with it. Hence this
patch is needed to work around this problem in the kernel.
This change allows CPU hot removal to work for sPAPR.

Worse, the existing code was inconsistent about where it got the ram size

and sometimes a local 'ram_size' masking the global.
This cleans up the code to consistently use machine->ram_size, eliminating

Now that we have the generic MachineState, fold sPAPREnvironment into

This is mostly a matter of search and replace, although a few places which
relied on the global spapr variable are changed to find the structure via

XICS needs to know the upper value for cpu_index as it is used to compute
the number of servers:
smp_cpus * kvmppc_smt_threads() / smp_threads
When passing -smp cpus=1,threads=9 on a POWER8 host, we end up with:
1 * 8 / 9 = 0
... which leads to an assertion in both emulated:
Number of servers needs to be greater 0
Aborted (core dumped)
... and in-kernel XICS:
xics_kvm_realize: Assertion `icp->nr_servers' failed.
Aborted (core dumped)
With this patch, we are sure that nr_servers > 0. Passing the same bogus
-smp option then leads to:
qemu-system-ppc64: Cannot support more than 8 threads on PPC with KVM
... which is a lot more explicit than the XICS errors.

target-ppc: fix hugepage support when using memory-backend-file
Current PPC code relies on -mem-path being used in order for
hugepage support to be detected. With the introduction of
MemoryBackendFile we can now handle this via:
-object memory-file-backend,mem-path=...,id=hugemem0 \
-numa node,id=mem0,memdev=hugemem0
Management tools like libvirt treat the 2 approaches as
interchangeable in some cases, which can lead to user-visible
regressions even for previously supported guest configurations.
Fix these by also iterating through any configured memory
backends that may be backed by hugepages.
Since the old code assumed hugepages always backed the entirety
of guest memory, play it safe an pick the minimum across the
max pages sizes for all backends, even ones that aren't backed
by hugepages.

macio: remove nonexistent interrupt on pin 1
The current macio implementation declares an interrupt that doesn't appear to
exist in the hardware or any other emulator implementation. OpenBIOS detects
this interrupt and generates an 'interrupts' property in the macio device tree
entry. Mac OS 9 halts boot when it detects this interrupt, so it has been
removed to permit further progress in the boot process.

target-i386: avoid overflow in the tsc-frequency property
The TSC frequency fits comfortably in an int when expressed in kHz,
but it may overflow when converted to Hz. In this case,
tsc-frequency returns a negative value because x86_cpuid_get_tsc_freq
does a 32-bit multiplication before assigning to int64_t.
For simplicity just make tsc_khz a 64-bit value.

block/raw-posix: Don't think /dev/fd/<NN> is a floppy drive.
In libguestfs we use /dev/fd/<NN> to pass pre-opened file descriptors
to qemu-img. Lately I've discovered that although this works, qemu
believes that these are floppy disk images. That in itself isn't much
of a problem, but now qemu prints a warning about host floppy
pass-thru being deprecated.
Extend the existing test so that it ignores /dev/fd/ as well as
/dev/fdset/
A simple test of this, if you are using the bash shell, is:
qemu-img info <( cat /dev/null )
without this patch:
$ qemu-img info <( cat /dev/null )
qemu-img: Host floppy pass-through is deprecated
Support for it will be removed in a future release.

migration: create new section to store global state
This includes a new section that for now just stores the current qemu state.
Right now, there are only one way to control what is the state of the
target after migration.
- If you run the target qemu with -S, it would start stopped.
- If you run the target qemu without -S, it would run just after migration finishes.
The problem here is what happens if we start the target without -S and
there happens one error during migration that puts current state as
-EIO. Migration would ends (notice that the error happend doing block
IO, network IO, i.e. nothing related with migration), and when
migration finish, we would just "continue" running on destination,
probably hanging the guest/corruption data, whatever.

Fail more cleanly in mismatched RAM cases

destination, QEMU would hang waiting for a disconnect on the source
and wouldn't release from that hang until the destination was manually
killed.
Mark the stream as being in error, this causes the destination to die
and the source to carry on.

Sort destination RAMBlocks to be the same as the source
Use the order of incoming RAMBlocks from the source to record
an index number; that then allows us to sort the destination
local RAMBlock list to match the source.
Now that the RAMBlocks are known to be in the same order, this
simplifies the RDMA Registration step which previously tried to
match RAMBlocks based on offset (which isn't guaranteed to match).
Looking at the existing compress code, I think it was erroneously
relying on an assumption of matching ordering, which this fixes.

Rework ram_control_load_hook to hook during block load
We need the names of RAMBlocks as they're loaded for RDMA,
reuse a slightly modified ram_control_load_hook:
a) Pass a 'data' parameter to use for the name in the block-reg
case
b) Only some hook types now require the presence of a hook function.

Translate offsets to destination address space
The 'offset' field in RDMACompress and 'current_addr' field
in RDMARegister are commented as being offsets within a particular
RAMBlock, however they appear to actually be offsets within the
ram_addr_t space.
The code currently assumes that the offsets on the source/destination
match, this change removes the need for the assumption for these
structures by translating the addresses into the ram_addr_t space of
the destination host.
Note: An alternative would be to change the fields to actually
take the data they're commented for; this would potentially be
simpler but would break stream compatibility for those cases
that currently work.

In a later patch the block name will be used to match up two views

list.
(At some point it could be argued that it would be best just to let

Only try and read a VMDescription if it should be there
The VMDescription section maybe after the EOF mark, the current code
does a 'qemu_get_byte' and either gets the header byte identifying the
description or an error (which it ignores). Doing the 'get' upsets
RDMA which hangs on old machine types without the VMDescription.
Just avoid reading the VMDescription if we wouldn't send it.

rocker: mark copy-to-cpu pkts as forwarding offloaded
For pkts copied to the CPU (to be processed by guest driver), mark the Rx
descriptor with flag "OFFLOAD_FWD" to indicate device has already forwarded
pkt. The guest driver will use this indicator to avoid duplicate
forwarding in the guest OS.
Examples include bcast/mcast/unknown ucast pkts flooded to bridged ports.
We want to avoid both the device and the guest bridge driver flooding these
pkts, which would result in duplicates pkts on the wire. Packet sampling,
such as sFlow, can also use this technique to mark pkts for the guest OS to
record but otherwise drop.

rocker: don't queue receive pkts when port is disabled
Commit 6e99c63 ("net/socket: Drop net_socket_can_send") changed the
semantics around .can_receive for sockets to now require the device to
flush queued pkts when transitioning to a .can_receive=true state. Rocker
device was not flushing the queue on .can_receive=true transition, so the
receiver was stuck.
But, turns out we really don't want any queuing at all on the port when the
port is disabled, otherwise when the port transitions to enabled, we'd
receive and forward stale pkts that really should have been dropped. So,
let's remove .can_receive so avoid queuing and drop the pkt in .receive if
the port is disabled.

vmxnet3: Fix incorrect small packet padding
When running ESXi under qemu there is an issue with the ESXi guest
discarding packets that are too short. The guest discards any packets
under the normal minimum length for an ethernet packet (60). This
results in odd behaviour where other hosts or VMs on other hosts can
communicate with the ESXi guest just fine (since there's a physical NIC
somewhere doing padding), but VMs on the host and the host itself cannot
because the ARP request packets are too small for the ESXi host to
accept.
Someone in the past thought this was worth fixing, and added code to the
vmxnet3 qemu emulation such that if it is receiving packets smaller than
60 bytes to pad the packet out to 60. Unfortunately this code is wrong
(or at least in the wrong place). It does so BEFORE before taking into
account the vnet_hdr at the front of the packet added by the tap device.
As a result, it might add padding, but it never adds enough.
Specifically it adds 10 less (the length of the vnet_hdr) than it needs
to.
The following (hopefully "obviously correct") patch simply swaps the
order of processing the vnet header and the padding. With this patch an
ESXi guest is able to communicate with the host or other local VMs.

e1000: flush packets when link comes up
e1000_can_receive() checks the link up status register bit. If the bit

avoid wasting CPU reading packets that cannot be delivered. The queue
must be flushed once the link comes back up again.
This patch fixes broken e1000 receive with Mac OS X Snow Leopard guests
and tap networking. Flushing the queue invokes the async send callback,
which re-enables tap fd read.

ich9: add TCO interface emulation
This interface provides some registers within a 32-byte range and can be
acessed through PCI-to-LPC bridge interface (PMBASE + 0x60).
It's commonly used as a watchdog timer to detect system lockups through
SMIs that are generated -- if TCO_EN bit is set -- on every timeout. If
NO_REBOOT bit is not set in GCS (General Control and Status register),
the system will be resetted upon second timeout if TCO_RLD register
wasn't previously written to prevent timeout.
This patch adds support to TCO watchdog logic and few other features
like mapping NMIs to SMIs (NMI2SMI_EN bit), system intruder detection,
etc. are not implemented yet.

crypto: introduce new module for computing hash digests
Introduce a new crypto/ directory that will (eventually) contain
all the cryptographic related code. This initially defines a
wrapper for initializing gnutls and for computing hashes with
gnutls. The former ensures that gnutls is guaranteed to be
initialized exactly once in QEMU regardless of CLI args. The
block quorum code currently fails to initialize gnutls so it
only works by luck, if VNC server TLS is not requested. The
hash APIs avoids the need to litter the rest of the code with
preprocessor checks and simplifies callers by allocating the
correct amount of memory for the requested hash.

block: update bdrv_drain_all()/bdrv_drain() comments
The doc comments for bdrv_drain_all() and bdrv_drain() are outdated:
* The bdrv_drain() comment is a poor man's bdrv_lock()/bdrv_unlock()
which Fam Zheng is currently developing. Unfortunately this warning
was never really enough because devices keep submitting I/O and op
blockers don't prevent that.
* The bdrv_drain_all() comment is still partially correct but reflects
the nature of the implementation rather than API documentation.
Do make it clear that bdrv_drain() is only appropriate within an
AioContext. For anything spanning AioContexts you need
bdrv_drain_all().

vl: move rom_load_all after machine init done
On ARM, commit ac9d32e39664e060cd1b538ff190980d57ad69e4 postponed the
memory preparation for boot until the machine init done notifier. This
has for consequence to insert ROM at machine init done time.
However the rom_load_all function stayed called before the ROM are
inserted. As a consequence the rom_load_all function does not do
everything it is expected to do, on ARM.
It currently registers the ROM reset notifier but does not iterate through
the registered ROM list. the isrom field is not set properly. This latter
is used to report info in the monitor and also to decide whether the
rom->data can be freed on ROM reset notifier.
To fix that regression the patch moves the rom_load_all call after
machine init done. We also take the opportunity to rename the rom_load_all
function into rom_check_and_resgister_reset() and integrate the
rom_load_done in it.

vfio/pci : Add pba_offset PCI quirk for Chelsio T5 devices
Fix pba_offset initialization value for Chelsio T5 Virtual Function
device. The T5 hardware has a bug in it where it reports a Pending Interrupt
Bit Array Offset of 0x8000 for its SR-IOV Virtual Functions instead
of the 0x1000 that the hardware actually uses internally. As the hardware
doesn't return the correct pba_offset value, add a quirk to instead
return a hardcoded value of 0x1000 when a Chelsio T5 VF device is
detected.
This bug has been fixed in the Chelsio's next chip series T6 but there are
no plans to respin the T5 ASIC for this bug. It is just documented in the
T5 Errata and left it at that.

vfio: Unregister IOMMU notifiers when container is destroyed
On systems with guest visible IOMMU, adding a new memory region onto
PCI bus calls vfio_listener_region_add() for every DMA window. This
installs a notifier for IOMMU memory regions. The notifier is supposed
to be removed vfio_listener_region_del(), however in the case of mixed
PHB (emulated + VFIO devices) when last VFIO device is unplugged and
container gets destroyed, all existing DMA windows stay alive altogether
with the notifiers which are on the linked list which head was in
the destroyed container.
This unregisters IOMMU memory region notifier when a container is
destroyed.

hw/vfio/platform: add irqfd support
This patch aims at optimizing IRQ handling using irqfd framework.
Instead of handling the eventfds on user-side they are handled on
kernel side using
- the KVM irqfd framework,
- the VFIO driver virqfd framework.
the virtual IRQ completion is trapped at interrupt controller
This removes the need for fast/slow path swap.
Overall this brings significant performance improvements.

cpu-all: complete "real" host page size API
Currently the "host" page size alignment API is really aligning to both
host and target page sizes. There is the qemu_real_page_size which can
be used for the actual host page size but it's missing a mask and ALIGN
macro as provided for qemu_page_size. Complete the API. This allows
system level code that cares about the host page size to use a
consistent alignment interface without having to un-needingly align to
the target page size. This also reduces system level code dependency
on the cpu specific TARGET_PAGE_SIZE.

exec: skip MMIO regions correctly in cpu_physical_memory_write_rom_internal
Loading the BIOS in the mac99 machine is interesting, because there is a
PROM in the middle of the BIOS region (from 16K to 32K). Before memory
region accesses were clamped, when QEMU was asked to load a BIOS from
0xfff00000 to 0xffffffff it would put even those 16K from the BIOS file
into the region. This is weird because those 16K were not actually
visible between 0xfff04000 and 0xfff07fff. However, it worked.
After clamping was added, this also worked. In this case, the
cpu_physical_memory_write_rom_internal function split the write in
three parts: the first 16K were copied, the PROM area (second 16K) were
ignored, then the rest was copied.
Problems then started with commit 965eb2f (exec: do not clamp accesses
to MMIO regions, 2015-06-17). Clamping accesses is not done for MMIO
regions because they can overlap wildly, and MMIO registers can be
expected to perform full-width accesses based only on their address
(with no respect for adjacent registers that could decode to completely
different MemoryRegions). However, this lack of clamping also applied
to the PROM area! cpu_physical_memory_write_rom_internal thus failed
to copy the third range above, i.e. only copied the first 16K of the BIOS.
In effect, address_space_translate is expecting _something else_ to do
the clamping for MMIO regions if the incoming length is large. This
"something else" is memory_access_size in the case of address_space_rw,
so use the same logic in cpu_physical_memory_write_rom_internal.

Stop including qemu-common.h in memory.h
Including qemu-common.h from other header files is generally a bad
idea, because it means it's very easy to end up with a circular
dependency. For instance, if we wanted to include memory.h from
qom/cpu.h we'd end up with this loop:
memory.h -> qemu-common.h -> cpu.h -> cpu-qom.h -> qom/cpu.h -> memory.h
Remove the include from memory.h. This requires us to fix up a few
other files which were inadvertently getting declarations indirectly
through memory.h.
The biggest change is splitting the fprintf_function typedef out
into its own header so other headers can get at it without having
to include qemu-common.h.

arm_mptimer: Fix timer shutdown and mode change
The running timer can't be stopped because timer control code just
doesn't handle disabling the timer. Fix it by deleting the timer if
the enable bit is cleared.
The timer won't start periodic ticking if a ONE-SHOT -> PERIODIC mode
change happens after a one-shot tick was completed. Fix it by
re-starting ticking if the timer isn't ticking right now.
To avoid code churning, these two fixes are squashed in one commit.

hw/intc/arm_gic_common.c: Reset all registers
The arm_gic_common reset function was missing reset code for
several of the GIC's state fields:
* bpr[]
* abpr[]
* priority1[]
* priority2[]
* sgi_pending[]
* irq_target[] (SMP configurations only)
These probably went unnoticed because most guests will either
never touch them, or will write to them in the process of
configuring the GIC before enabling interrupts.

target-arm: Split DISAS_YIELD from DISAS_WFE
Currently we use DISAS_WFE for both WFE and YIELD instructions.
This is functionally correct because at the moment both of them
are implemented as "yield this CPU back to the top level loop so
another CPU has a chance to run". However it's rather confusing
that YIELD ends up calling HELPER(wfe), and if we ever want to
implement real behaviour for WFE and SEV it's likely to trip us up.
Split out the yield codepath to use DISAS_YIELD and a new
HELPER(yield) function, and have HELPER(wfe) call HELPER(yield).

ahci: fix sdb fis semantics
There are two things to fix here:
The first one is subtle: the PxSACT register in the AHCI HBA has different
semantics from the field it is shadowing, the ACT field in the
Set Device Bits FIS.
In the HBA register, PxSACT acts as a bitfield indicating outstanding
NCQ commands where a set bit indicates a pending NCQ operation. The FIS
field however operates as an RWC register update to PxSACT, where a set
bit indicates a *successfully* completed command.
Correct the FIS semantics. At the same time, move the "clear finished"
action to the SDB FIS generation instead of the register read to mimick
how the other shadow registers work, which always just report the last
reported value from a FIS, and not the most current values which may
not have been reported by a FIS yet.
Lastly and more simply, SATA 3.2 section 13.6.4.2 (and later sections)
all specify that the Interrupt bit for the SDB FIS should always be set
to one for NCQ commands. That's currently the only time we generate this
FIS, so set it on all the time.

ahci: Do not map cmd_fis to generate response
The Register D2H FIS should copy the current values of
the registers instead of just parroting back the same
values the guest sent back to it.
In this case, the SECTOR COUNT variables are actually
not generally meaningful in terms of standard commands
(See ATA8-AC3 Section 9.2 Normal Outputs), so it actually
probably doesn't matter what we put in here.
Meanwhile, we do need to use the Register update FIS from
the NCQ pathways (in error cases), so getting rid of
references to cur_cmd here is a win for AHCI concurrency.

ahci: add get_cmd_header helper
cur_cmd is an internal bookmark that points to the
current AHCI Command Header being processed by the
AHCI state machine. With NCQ needing to occasionally
rely on some of the same AHCI helpers, we cannot use
cur_cmd and will need to grab explicit pointers instead.
In an attempt to begin relying on the cur_cmd pointer
less, add a helper to let us specifically get the pointer
to the command header of particular interest.

ahci: add cmd header to ncq transfer state
While the rest of the AHCI device can rely on a single bookmarked

Add a cmdh pointer to the ncq_tfs object and make the sglist prepare
function take an AHCICmdHeader pointer so we can be explicit about
where we'd like to build SGlists from.

ahci: correct ncq sector count
uint16_t isn't enough to hold the real sector count, since a value of
zero implies a full 64K sectors, so we need a uint32_t here.
We *could* cheat and pretend that this value is 0-based and fit it in
a uint16_t, but I'd rather waste 2 bytes instead of a future dev's
10 minutes when they forget to +1/-1 accordingly somewhere.

ide: add limit to .prepare_buf()
prepare_buf should not always grab as many descriptors
as it can, sometimes it should self-limit.
For example, an NCQ transfer of 1 sector with a PRDT that
describes 4GiB of data should not copy 4GiB of data, it
should just transfer that first 512 bytes.
PIO is not affected, because the dma_buf_rw dma helpers
already have a byte limit built-in to them, but DMA/NCQ
will exhaust the entire list regardless of requested size.
AHCI 1.3 specifies in section 6.1.6 Command List Underflow that
NCQ is not required to detect underflow conditions. Non-NCQ
pathways signal underflow by writing to the PRDBC field, which
will already occur by writing the actual transferred byte count
to the PRDBC, signaling the underflow.
Our NCQ pathways aren't required to detect underflow, but since our DMA
backend uses the size of the PRDT to determine the size of the transer,
if our PRDT is bigger than the transaction (the underflow condition) it
doesn't cost us anything to detect it and truncate the PRDT.
This is a recoverable error and is not signaled to the guest, in either
NCQ or normal DMA cases.
For BMDMA, the existing pathways should see no guest-visible difference,
but any bytes described in the overage will no longer be transferred
before indicating to the guest that there was an underflow.

ahci/qtest: Execute IDENTIFY prior to data commands
If you try to execute an NCQ command before trying to engage with the
device by issuing an IDENTIFY command, the error bits that are part of
the signature will fool the test suite into thinking there was a failure.
Issue IDENTIFY first on "boot", which will clear the signature out of
the registers for us.

There's a handful of trivial bugs in the libqos/ahci functions,
squish them together.
- Zero cached pointers after freeing them
- The Command List Buffer is an array of 32x 32 byte structures, not
32x 8 byte pointers -- it's 1MiB, not 256 bytes. Zero it ALL.

ahci: Do not ignore memory access read size
The only guidance the AHCI specification gives on memory access is:
"Register accesses shall have a maximum size of 64-bits; 64-bit access
must not cross an 8-byte alignment boundary."
I interpret this to mean that aligned or unaligned 1, 2 and 4 byte
accesses should work, as well as aligned 8 byte accesses.
In practice, a real Q35/ICH9 responds to 1, 2, 4 and 8 byte reads
regardless of alignment. Windows 7 can be observed making 1 byte
reads to the middle of 32 bit registers to fetch error codes.
Introduce a wrapper to support unaligned accesses to AHCI.
This wrapper will support aligned 8 byte reads, but will make
no effort to support unaligned 8 byte reads, which although they
will work on real hardware, are not guaranteed to work and do
not appear to be used by either Windows or Linux.

s390x/migration: Introduce 2.4 machine
The section footer changes commit f68945d42bab ("Add a protective
section footer") and commit 37fb569c0198 ("Disable section footers
on older machine types") broke migration for any non-versioned
machines.
This pinpoints a problem of s390-ccw machines: it needs to
be versioned to be compatible with future changes in common
code data structures such as section footers.
Let's introduce a version scheme for s390-ccw-virtio machines.
We will use the old s390-ccw-virtio name as alias to the latest
version as all existing libvirt XML for the ccw type were expanded
by libvirt to that name.
The only downside of this patch is, that the old alias s390-ccw
will no longer be available as machines can have only one alias,
but it should not really matter.

s390x/gdb: synchronize cpu state after modifying acrs
Whenever we touch the access control registers, we have to make sure that
the values will make it into kvm. Otherwise the change will simply be lost.
When synchronizing qemu and kvm, a normal KVM_PUT_RUNTIME_STATE does not take
care of these registers. Let's simply trigger a KVM_PUT_FULL_STATE sync,
so the values will directly be written to kvm. The performance overhead can
be ignored and this is much cleaner than manually writing these registers to kvm
via our two supported ways.

s390x/ipl: Fix boot if no bootindex was specified
commit fa92e218df1d ("s390x/ipl: avoid sign extension") introduced
a regression:
qemu-system-s390x -drive file=image.qcow,format=qcow2
does not boot, the bios states
"No virtio-blk device found!"
adding bootindex=1 does boot.
The reason is that the uint32_t as return value will not do the right
thing for the return -1 (default without bootindex).
The bios itself, will interpret a 64bit -1 as autodetect (but it will
interpret 32bit -1 as ccw device address ff.ff.ffff)

block: remove redundant check before g_slist_find()
An empty GSList is represented by a NULL pointer, therefore it's a
perfectly valid argument for g_slist_find() and there's no need to

block: Fix dirty bitmap in bdrv_co_discard
Unsetting dirty globally with discard is not very correct. The discard may zero
out sectors (depending on can_write_zeroes_with_unmap), we should replicate
this change to destination side to make sure that the guest sees the same data.
Calling bdrv_reset_dirty also troubles mirror job because the hbitmap iterator
doesn't expect unsetting of bits after current position.
So let's do it the opposite way which fixes both problems: set the dirty bits
if we are to discard it.

block/iscsi: add support for request timeouts
libiscsi starting with 1.15 will properly support timeout of iscsi
commands. The default will remain no timeout, but this can
be changed via cmdline parameters, e.g.:
qemu -iscsi timeout=30 -drive file=iscsi://...
If a timeout occurs a reconnect is scheduled and the timed out command
will be requeued for processing after a successful reconnect.
The required API call iscsi_set_timeout is present since libiscsi
1.10 which was released in October 2013. However, due to some bugs
in the libiscsi code the use is not recommended before version 1.15.
Please note that this patch bumps the libiscsi requirement to 1.10
to have all function and macros defined. The patch fixes also a
off-by-one error in the NOP timeout calculation which was fixed
while touching these code parts.

kvm: First step to push iothread lock out of inner run loop
This opens the path to get rid of the iothread lock on vmexits in KVM
mode. On x86, the in-kernel irqchips has to be used because we otherwise
need to synchronize APIC and other per-cpu state accesses that could be
changed concurrently.
Regarding pre/post-run callbacks, s390x and ARM should be fine without
specific locking as the callbacks are empty. MIPS and POWER require
locking for the pre-run callback.
For the handle_exit callback, it is non-empty in x86, POWER and s390.
Some POWER cases could do without the locking, but it is left in
place for now.

The MMIO case is further broken up in two cases: if the caller does not
hold the BQL on invocation, the unlocked one takes or avoids BQL depending
on the locking strategy of the target memory region and its coalesced
MMIO handling. In this case, the caller should not hold _any_ lock
(a friendly suggestion which is disregarded by virtio-scsi-dataplane).

main-loop: introduce qemu_mutex_iothread_locked
This function will be used to avoid recursive locking of the iothread lock
whenever address_space_rw/ld*/st* are called with the BQL held, which is
almost always the case.
Tracking whether the iothread is owned is very cheap (just use a TLS
variable) but requires some care because now the lock must always be
taken with qemu_mutex_lock_iothread(). Previously this wasn't the case.
Outside TCG mode this is not a problem. In TCG mode, we need to be
careful and avoid the "prod out of compiled code" step if already
in a VCPU thread. This is easily done with a check on current_cpu,
i.e. qemu_in_vcpu_thread().
Hopefully, multithreaded TCG will get rid of the whole logic to kick
VCPUs whenever an I/O event occurs!

Fix irq route entries exceeding KVM_MAX_IRQ_ROUTES
Last month, we experienced several guests crash(6cores-8cores), qemu logs
display the following messages:
qemu-system-x86_64: /build/qemu-2.1.2/kvm-all.c:976:
kvm_irqchip_commit_routes: Assertion `ret == 0' failed.
After analysis and verification, we can confirm it's irq-balance
daemon(in guest) leads to the assertion failure. Start a 8 core guest with
two disks, execute the following scripts will reproduce the BUG quickly:
irq_affinity.sh
========================================================================
vda_irq_num=25
vdb_irq_num=27
while [ 1 ]
do
for irq in {1,2,4,8,10,20,40,80}
do
echo $irq > /proc/irq/$vda_irq_num/smp_affinity
echo $irq > /proc/irq/$vdb_irq_num/smp_affinity
dd if=/dev/vda of=/dev/zero bs=4K count=100 iflag=direct
dd if=/dev/vdb of=/dev/zero bs=4K count=100 iflag=direct
done
done
========================================================================
QEMU setup static irq route entries in kvm_pc_setup_irq_routing(), PIC and
IOAPIC share the first 15 GSI numbers, take up 23 GSI numbers, but take up
38 irq route entries. When change irq smp_affinity in guest, a dynamic route
entry may be setup, the current logic is: if allocate GSI number succeeds,
a new route entry can be added. The available dynamic GSI numbers is
1021(KVM_MAX_IRQ_ROUTES-23), but available irq route entries is only
986(KVM_MAX_IRQ_ROUTES-38), GSI numbers greater than route entries.
irq-balance's behavior will eventually leads to total irq route entries
exceed KVM_MAX_IRQ_ROUTES, ioctl(KVM_SET_GSI_ROUTING) fail and
kvm_irqchip_commit_routes() trigger assertion failure.
This patch fix the BUG.

include/exec: Move tb hash functions out
This is one of very few things in exec-all with a genuine CPU
architecture dependency. Move these hashing helpers to a new
header to trim exec-all.h down to a near architecture-agnostic
header.
The defs are only used by cpu-exec and translate-all which are both
arch-obj's so the new tb-hash.h has no core code usage.

hw/arm/virt: Make block devices default to virtio
Now we have virtio-pci, we can make the virt board's default block
device type be IF_VIRTIO. This allows users to use simplified
command lines that don't have to explicitly create virtio-pci-blk
devices; the -hda &c very short options now also work.
This means we also need to set no_cdrom to avoid getting a
default cdrom device -- this is needed because the virtio-blk
device will fail if it is connected to a block backend with
no media, which is what the default cdrom device typically is.
Providing a cdrom with media via -cdrom will succeed, but silently
create a device with non-removable medium. this is probably
not really what the user wants, but is the best we can do now.
Note that this change means that some command lines which used
to work (by accident) will stop working. Where a drive was connected
manually to a device but without 'if=none' being specified, we
used to treat this as an IDE drive, which we would then not autoplug
because the board doesn't support IDE. Now we will treat it as a
virtio disk and autoplug it, which means the attempt to use the
drive manually will fail:
qemu-system-arm: -drive file=img.qcow2,id=foo: Drive 'foo' is already
in use because it has been automatically connected to another device
(did you need 'if=none' in the drive options?)
The command line will have to be changed to include 'if=none', as the
error message suggests.

qdev-properties-system: Improve error message for drive assignment conflict
If the user forgot if=none on their drive specification they're likely
to get an error message because the drive is assigned once automatically
by QEMU and once by the manual id=/drive= user command line specification.
Improve the error message produced in this case to explicitly guide the
user towards if=none.
We rephrase the "drive conflict but not for an if=something" error as
well to keep the wording in line.
The two cases that change are:
(1) Drive specified as to be auto-connected and also manually connected
(and the board does handle this if= type):
qemu-system-x86_64 -nodefaults -display none \
-drive if=scsi,file=tmp.qcow2,id=foo -device ide-hd,drive=foo
Previously:
qemu-system-x86_64: -device ide-hd,drive=foo: Property 'ide-hd.drive'
can't take value 'foo', it's in use
Now:
qemu-system-x86_64: -device ide-hd,drive=foo: Drive 'foo' is already in
use because it has been automatically connected to another device (did
you need 'if=none' in the drive options?)
(2) Drive specified to be manually connected in two different ways:
qemu-system-x86_64 -nodefaults -display none \
-drive if=none,file=tmp.qcow2,id=foo -device ide-hd,drive=foo \
-device ide-hd,drive=foo
Previously:
qemu-system-x86_64: -device ide-hd,drive=foo: Property 'ide-hd.drive'
can't take value 'foo', it's in use
Now:
qemu-system-x86_64: -device ide-hd,drive=foo: Drive 'foo' is already in
use by another device

qdev-properties-system: Change set_pointer's parse callback to use Error
Instead of having set_pointer() call a parse callback which returns
an error number that we then convert to an Error string with
error_set_from_qdev_prop_error(), make the parse callback take an
Error** and set the error itself. This will allow parse routines
to provide more helpful error messages than the generic ones.

(The PS data type is removed in the Release 6.)
Loongson-2E and Loongson-2F don't have any implementation field in
FCSR0(FIR) but do support PS data format, therefore for these cores RI will

hw/mips: Do not clear BEV for MIPS malta kernel load
The BEV flag controls whether the boot exception vector is still
in place when starting a kernel. When cleared the exception vector
at EBASE (or hard coded address of 0x80000000) is used instead.
The early stages of the linux kernel would benefit from BEV still
being set to ensure any faults get handled by the boot rom exception
handlers. This is a moot point for system qemu as there aren't really
any BEV handlers, but there are other good reasons to change this...
The UHI (semi-hosting interface) defines special behaviours depending
on whether an application starts in an environment with BEV set or
cleared. When BEV is set then UHI assumes that a bootloader is
relatively dumb and has no advanced exception handling logic.
However, when BEV is cleared then UHI assumes that the bootloader
has the ability to handle UHI exceptions with its exception handlers
and will unwind and forward UHI SYSCALL exceptions to the exception
vector that was installed prior to running the application.

hw/pci-bridge: format special OFW unit address for PXB host
We have agreed that OpenFirmware device paths in the "bootorder" fw_cfg
file should follow the pattern
/pci@i0cf8,%x/...
for devices that live behind an extra root bus. The extra root bus in
question is the %x'th among the extra root buses. (In other words, %x
gives the position of the affected extra root bus relative to the other
extra root buses, in bus_nr order.) %x starts at 1, and is formatted in
hex.
The portion of the unit address that comes before the comma is dynamically
taken from the main host bridge, similarly to sysbus_get_fw_dev_path().

hw/core: explicit OFW unit address callback for SysBusDeviceClass
The sysbus_get_fw_dev_path() function formats OpenFirmware device path
nodes ("driver-name@unit-address") for sysbus devices. The first choice
for "unit-address" is the base address of the device's first MMIO region.
The second choice is its first IO port.
However, if two sysbus devices with the same "driver-name" lack both MMIO
and PIO resources, then there is no good way to distinguish them based on
their OFW nodes, because in this case unit-address is omitted completely
for both devices. An example is TYPE_PXB_HOST ("pxb-host").
For the sake of such devices, introduce the explicit_ofw_unit_address()
"virtual member function". With this function, each sysbus device in the
same SysBusDeviceClass can state its own address.

hw/pci-bridge: disable SHPC in PXB
OVMF downloads the ACPI linker/loader script from QEMU when the edk2 PCI
Bus driver globally signals the firmware that PCI enumeration and resource
allocation have completed. At this point QEMU regenerates the ACPI payload
in an fw_cfg read callback, and this is when the PXB's _CRS gets
populated.
Unfortunately, when this happens, the PCI_COMMAND_MEMORY bit is clear in
the root bus's command register, *unlike* under SeaBIOS. The consequences
unfold as follows:
- When build_crs() fetches dev->io_regions[i].addr, it is all-bits-one,
because pci_update_mappings() --> pci_bar_address() calculated it as
PCI_BAR_UNMAPPED, due to the PCI_COMMAND_MEMORY bit being clear.
- Consequently, the SHPC MMIO BAR (bar 0) of the bridge is not added to
the _CRS, *despite* having been programmed in PCI config space.
- Similarly, the SHPC MMIO BAR of the PXB is not removed from the main
root bus's DWordMemory descriptor.
- Guest OSes (Linux and Windows alike) notice the pre-programmed SHPC BAR
within the PXB's config space, and notice that it conflicts with the
main root bus's memory resource descriptors. Linux reports
pci 0000:04:00.0: BAR 0: can't assign mem (size 0x100)
pci 0000:04:00.0: BAR 0: trying firmware assignment [mem
0x88200000-0x882000ff 64bit]
pci 0000:04:00.0: BAR 0: [mem 0x88200000-0x882000ff 64bit] conflicts
with PCI Bus 0000:00 [mem
0x88200000-0xfebfffff]
While Windows Server 2012 R2 reports
https://technet.microsoft.com/en-us/library/cc732199%28v=ws.10%29.aspx
This device cannot find enough free resources that it can use. If you
want to use this device, you will need to disable one of the other
devices on this system. (Code 12)
This issue was apparently encountered earlier, see the "hack" in:
https://lists.nongnu.org/archive/html/qemu-devel/2015-01/msg02983.html
and the current hole-punching logic in build_crs() and build_ssdt() is
probably supposed to remedy exactly that problem -- however, for OVMF they
don't work, because at the end of the PCI enumeration and resource
allocation, which cues the ACPI linker/loader client, the command register
is clear.
The "shpc" property of "pci-bridge", introduced in the previous patches,
allows us to disable the standard hotplug controller cleanly, eliminating
the SHPC bar and the conflict.

hw/pci-bridge: introduce "shpc" property
In the PCI expander bridge, we will want to disable those features of
pci-bridge that relate to SHPC (standard hotplug controller):
- SHPC bar and underlying MemoryRegion
- interrupt (INTx or MSI)
- effective hotplug callbacks
- other SHPC hooks (initialization, cleanup, migration etc)
Introduce a new feature request bit in the PCIBridgeDev.flags field, and
turn off the above if the bit is explicitly cleared.

commit 3de3d698d942d1116152417f882c897b26b44e41
Author: Wolfgang Bumiller <w.bumiller@proxmox.com>
Date: Thu May 21 14:33:29 2015 +0200
util/qemu-sockets: improve ai_flag hints for ipv6 hosts
*) Do not use AI_ADDRCONFIG on listening sockets, because this flag
makes it impossible to explicitly listen on '127.0.0.1' if no global
ipv4 address is configured additionally, making this a very
uncomfortable option.
*) Add AI_V4MAPPED hint for connecting sockets.
If your system is globally only connected via ipv6 you often still want
to be able to use '127.0.0.1' and 'localhost' (even if localhost doesn't
also have an ipv6 entry).
For example, PVE - unless explicitly asking for insecure mode - uses
ipv4 loopback addresses with QEMU for live migrations tunneled over SSH.
These fail to start because AI_ADDRCONFIG makes getaddrinfo refuse to
work with '127.0.0.1'.
As for the AI_V4MAPPED flag: glibc uses it by default, and providing
non-0 flags removes it. I think it makes sense to use it.
I also want to point out that glibc explicitly sidesteps POSIX standards
when passing 0 as hints by then assuming both AI_V4MAPPED and
AI_ADDRCONFIG (the latter being a rather weird choice IMO), while
according to POSIX.1-2001 it should be assumed 0. (glibc considers its
choice an improvement.)
Since either AI_CANONNAME or AI_PASSIVE are passed in our cases, glibc's
default flags in turn are disabled again unless explicitly added, which
I do with this patch.

remove libdecnumber/dpd/decimal128Local.h
Commit 72ac97cdfc added two equivalent versions of decimal128Local.h,
one in libdecnumber/dpd/ and another in include/libdecnumber/dpd/.
Being identical by the code, the two files however differs in the
licensing terms. The one in libdecnumber/dpd/ (which is being
removed by this patch) is licensed as GPL3.1 (plus gcc runtime
exception), which, as far as I know, is not compatible with GPL-2.
This file is not used (it is included from
include/libdecnumber/dpd/decimal128.h, so version in include/ is
used).
More, the version in include/ can also be removed, since none
of the 3 defines from that file are actually used by the code.
Even more, one of the defines from there, decimal128SetSign,
is redefined (to equivalent value) in libdecnumber/dpd/decimal128.c,
but again, never used.
What a mess...

Revert "xen-hvm: increase maxmem before calling xc_domain_populate_physmap"
This reverts commit c1d322e6048796296555dd36fdd102d7fa2f50bf.
The original commit fixes a bug when assigning a large number of
devices which require option roms to a guest. (One known
configuration that needs extra memory is having more than 4 emulated
NICs assigned. Three or fewer NICs seems to work without this
functionality.)
However, by unilaterally increasing maxmem, it introduces two
problems.
First, now libxl's calculation of the required maxmem during migration
is broken -- any guest which exercised this functionality will fail on
migration. (Guests which have the default number of devices are not
affected.)
Secondly, it makes it impossible for a higher-level toolstack or
administer to predict how much memory a VM will actually use, making
it much more difficult to effectively use all of the memory on a
machine.

Expecting the ROM BAR to be written with an all ones value when sizing
the region is wrong - the low bit has another meaning (enable/disable)

balloon: add a feature bit to let Guest OS deflate balloon on oom
Excessive virtio_balloon inflation can cause invocation of OOM-killer,
when Linux is under severe memory pressure. Various mechanisms are
responsible for correct virtio_balloon memory management. Nevertheless it
is often the case that these control tools does not have enough time to
react on fast changing memory load. As a result OS runs out of memory and
invokes OOM-killer. The balancing of memory by use of the virtio balloon
should not cause the termination of processes while there are pages in the
balloon. Now there is no way for virtio balloon driver to free memory at
the last moment before some process get killed by OOM-killer.
This does not provide a security breach as balloon itself is running
inside Guest OS and is working in the cooperation with the host. Thus
some improvements from Guest side should be considered as normal.
To solve the problem, introduce a virtio_balloon callback which is
expected to be called from the oom notifier call chain in out_of_memory()
function. If virtio balloon could release some memory, it will make the
system return and retry the allocation that forced the out of memory
killer to run.
This behavior should be enabled if and only if appropriate feature bit
is set on the device. It is off by default.
This functionality was recently merged into vanilla Linux.

raw-posix: Introduce hdev_is_sg()
Until now, an SG device was identified only by checking if its path
started with "/dev/sg". Then, hdev_open() would set the bs->sg flag
accordingly. The patch relies on the actual properties of the device
instead of the specified file path.
To this end, test for an SG device (e.g. /dev/sg0) by ensuring that
all of the following holds:
- The specified file name corresponds to a character device
- The device supports the SG_GET_VERSION_NUM ioctl
- The device supports the SG_GET_SCSI_ID ioctl

Fix migration in case of scsi-generic
During migration, QEMU uses fsync()/fdatasync() on the open file
descriptor for read-write block devices to flush data just before
stopping the VM.
However, fsync() on a scsi-generic device returns -EINVAL which
causes the migration to fail. This patch skips flushing data in case
of an SG device, since submitting SCSI commands directly via an SG
character device (e.g. /dev/sg0) bypasses the page cache completely,
anyway.
Note that fsync() not only flushes the page cache but also the disk
cache. The scsi-generic device never sends flushes, and for
migration it assumes that the same SCSI device is used by the
destination host, so it does not issue any SCSI SYNCHRONIZE CACHE
(10) command.
Finally, remove the bdrv_is_sg() test from iscsi_co_flush() since
this is now redundant (we flush the underlying protocol at the end
of bdrv_co_flush() which, with this patch, we never reach).

virtio-blk: Use blk_drain() to drain IO requests

which works for all existing BlockDriverStates, while draining only
one is needed.
This patch replaces blk_drain_all() by blk_drain() in
virtio_blk_reset(). virtio_blk_data_plane_stop() should be called
after draining because it restores vblk->complete_request.

throttle: Check current timers before updating any_timer_armed[]
Calling throttle_group_config() cancels all timers from a particular
BlockDriverState, so any_timer_armed[] should be updated accordingly.
However, with the current code it may happen that a timer is armed in
a different BlockDriverState from the same group, so any_timer_armed[]
would be set to false in a situation where there is still a timer
armed.
The consequence is that we might end up with two timers armed. This
should not have any noticeable impact however, since all accesses to
the ThrottleGroup are protected by a lock, and the situation would
become normal again shortly thereafter as soon as all timers have been
fired.
The correct way to solve this is to check that we're actually
cancelling a timer before updating any_timer_armed[].

block: Let bdrv_drain_all() to call aio_poll() for each AioContext
After the commit 9b536adc ("block: acquire AioContext in
bdrv_drain_all()") the aio_poll() function got called for every
BlockDriverState, in assumption that every device may have its own
AioContext. If we have thousands of disks attached, there are a lot of
BlockDriverStates but only a few AioContexts, leading to tons of
unnecessary aio_poll() calls.
This patch changes the bdrv_drain_all() function allowing it find shared
AioContexts and to call aio_poll() only for unique ones.

qmp: Wean off qerror_report()
The traditional QMP command handler interface
int qmp_FOO(Monitor *mon, const QDict *params, QObject **ret_data);
doesn't provide for returning an Error object. Instead, the handler
is expected to stash it in the monitor with qerror_report().
When we rebased QMP on top of QAPI, we didn't change this interface.
Instead, commit 776574d introduced "middle mode" as a temporary aid
for converting existing QMP commands to QAPI one by one. More than
three years later, we're still using it.
Middle mode has two effects:
* Instead of the native input marshallers
static void qmp_marshal_input_FOO(QDict *, QObject **, Error **)
it generates input marshallers conforming to the traditional QMP
command handler interface.
* It suppresses generation of code to register them with
qmp_register_command()
This permits giving them internal linkage.
As long as we need qmp-commands.hx, we can't use the registry behind
qmp_register_command(), so the latter has to stay for now.
The former has to go to get rid of qerror_report(). Changing all QMP
commands to fit the QAPI mold in one go was impractical back when we
started, but by now there are just a few stragglers left:
do_qmp_capabilities(), qmp_qom_set(), qmp_qom_get(), qmp_object_add(),
qmp_netdev_add(), do_device_add().
Switch middle mode to generate native input marshallers, and adapt the
stragglers. Simplifies both the monitor code and the stragglers.
Rename do_qmp_capabilities() to qmp_capabilities(), and
do_device_add() to qmp_device_add, because that's how QMP command
handlers are named today.

qerror: Clean up QERR_ macros to expand into a single string
These macros expand into error class enumeration constant, comma,
string. Unclean. Has been that way since commit 13f59ae.
The error class is always ERROR_CLASS_GENERIC_ERROR since the previous
commit.
Clean up as follows:
* Prepend every use of a QERR_ macro by ERROR_CLASS_GENERIC_ERROR, and
delete it from the QERR_ macro. No change after preprocessing.
* Rewrite error_set(ERROR_CLASS_GENERIC_ERROR, ...) into
error_setg(...). Again, no change after preprocessing.

QemuOpts: Wean off qerror_report_err()
qerror_report_err() is a transitional interface to help with
converting existing monitor commands to QMP. It should not be used
elsewhere.
The only remaining user in qemu-option.c is qemu_opts_parse(). Is it
used in QMP context? If not, we can simply replace
qerror_report_err() by error_report_err().
The uses in qemu-img.c, qemu-io.c, qemu-nbd.c and under tests/ are
clearly not in QMP context.
The uses in vl.c aren't either, because the only QMP command handlers
there are qmp_query_status() and qmp_query_machines(), and they don't
call it.
Remaining uses:
* drive_def(): Command line -drive and such, HMP drive_add and pci_add
* hmp_chardev_add(): HMP chardev-add
* monitor_parse_command(): HMP core
* tmp_config_parse(): Command line -tpmdev
* net_host_device_add(): HMP host_net_add
* net_client_parse(): Command line -net and -netdev
* qemu_global_option(): Command line -global
* vnc_parse_func(): Command line -display, -vnc, default display, HMP
change, QMP change. Bummer.
* qemu_pci_hot_add_nic(): HMP pci_add
* usb_net_init(): Command line -usbdevice, HMP usb_add
Propagate errors through qemu_opts_parse(). Create a convenience
function qemu_opts_parse_noisily() that passes errors to
error_report_err(). Switch all non-QMP users outside tests to it.
That leaves vnc_parse_func(). Propagate errors through it. Since I'm
touching it anyway, rename it to vnc_parse().

qdev-monitor: Fix check for full bus
Property bus has always been too screwed up to be really usable for
values other than plain bus IDs. This just fixes a bug that crept in
in commit 1395af6 "qdev: add a maximum device allowed field for the
bus."
It doesn't always fail when it should:
$ qemu-system-x86_64 -nodefaults -device virtio-serial-pci -device virtio-rng-device,bus=pci.0/virtio-serial-pci/virtio-bus
Happily plugs the virtio-rng-device into the virtio-bus provided by
virtio-serial-pci, even though its only slot is already occupied by a
virtio-serial-device.
And sometimes fails when it shouldn't:
$ qemu-system-x86_64 -nodefaults -device virtio-serial-pci -device virtserialport,bus=virtio-bus/virtio-serial-device
Yes, the virtio-bus is full, but the virtio-serial-bus provided by
virtio-serial-device isn't, and that's the one we're trying to use.
Root cause: we check "bus full" when we resolve the first element of
the path. That's the correct one only when it's also the last one.
Fix by moving the "bus full" check to right before we return a bus.

qemu-system-x86_64: -device virtio-rng-device,bus=virtio-bus: Bus 'virtio-bus' is full

qemu-system-x86_64: -device virtio-rng-device,bus=virtio-bus: Bus 'virtio-bus' not found
qbus_find_recursive() reports the "is full" error itself, and leaves
reporting "not found" to its caller. The result is confusion. Write
it a function contract that permits leaving all error reporting to the
caller, and implement it. Update callers to detect and report "is
full".
Screwed up when commit 1395af6 added the max_dev limit and the "is

all the target agnostic users really just want the cpu pointer. These
users then need to use the target-specifically defined ENV_GET_CPU to
navigate back up to the CPU from the ENV. Split the API for the two
uses cases to remove all need for ENV_GET_CPU.

m68k: fix usp processing on interrupt entry and exception exit
The action to potentially switch sp register is not occurring at the correct
point in the interrupt entry or exception exit sequences.
For the interrupt entry case the sp on entry is used to create the stack
exception frame - but this may well be the user stack pointer, since we
haven't done the switch yet. Re-order the flow to switch the sp regs then
use the current sp to create the exception frame.
For the return from exception case the code is unwinding the sp after
switching sp registers. But it should always unwind the supervisor sp
first, then carry out any required sp switch.
Note that these problems don't effect operation unless the user sp bit is
set in the CACR register. Only a single sp is used in the default power up
state. Previously Linux only used this single sp mode. But modern versions
of Linux use the user sp mode now, so we need correct behavior for Linux
to work.

qom: Don't pass string table to object_get_enum() function
Now that properties can be explicitly registered as an enum
type, there is no need to pass the string table to the
object_get_enum() function. The object property registration
already has a pointer to the string table.
In changing this method signature, the hostmem backend object
has to be converted to use the new enum property registration
code, which simplifies it somewhat.

qom: Add an object_property_add_enum() helper function
A QOM property can be parsed as enum using the visit_type_enum()
helper function, but this forces callers to use the more complex
generic object_property_add() method when registering it. It
also requires that users of that object have access to the
string map when they want to read the property value.
This patch introduces a specialized object_property_add_enum()
method which simplifies the use of enum properties, so the
setters/getters directly get passed the int value.
typedef enum {
MYDEV_TYPE_FROG,
MYDEV_TYPE_ALLIGATOR,
MYDEV_TYPE_PLATYPUS,
MYDEV_TYPE_LAST
} MyDevType;
Then provide a table of enum <-> string mappings
static const char *const mydevtypemap[MYDEV_TYPE_LAST + 1] = {
[MYDEV_TYPE_FROG] = "frog",
[MYDEV_TYPE_ALLIGATOR] = "alligator",
[MYDEV_TYPE_PLATYPUS] = "platypus",
[MYDEV_TYPE_LAST] = NULL,
};
Assuming an object struct of
typedef struct {
Object parent_obj;
MyDevType devtype;
...other fields...
} MyDev;
The property can then be registered as follows:
static int mydev_prop_get_devtype(Object *obj,
Error **errp G_GNUC_UNUSED)
{
MyDev *dev = MYDEV(obj);
return dev->devtype;
}
static void mydev_prop_set_devtype(Object *obj,
int value,
Error **errp G_GNUC_UNUSED)
{
MyDev *dev = MYDEV(obj);
dev->devtype = value;
}
object_property_add_enum(obj, "devtype",
mydevtypemap, "MyDevType",
mydev_prop_get_devtype,
mydev_prop_set_devtype,
NULL);
Note there is no need to check the range of 'value' in
the setter, because the string->enum conversion code will
have already done that and reported an error as required.

qom: Add object_new_with_props() / object_new_withpropv() helpers
It is reasonably common to want to create an object, set a
number of properties, register it in the hierarchy and then
mark it as complete (if a user creatable type). This requires
quite a lot of error prone, verbose, boilerplate code to achieve.
First a pair of functions object_set_props() / object_set_propv()
are added which allow for a list of objects to be set in
one single API call.
Then object_new_with_props() / object_new_with_propv() constructors
are added which simplify the sequence of calls to create an
object, populate properties, register in the object composition
tree and mark the object complete, into a single method call.
Usage would be:
Error *err = NULL;
Object *obj;
obj = object_new_with_propv(TYPE_MEMORY_BACKEND_FILE,
object_get_objects_root(),
"hostmem0",
&err,
"share", "yes",
"mem-path", "/dev/shm/somefile",
"prealloc", "yes",
"size", "1048576",
NULL);
Note all property values are passed in string form and will
be parsed into their required data types, using normal QOM
semantics for parsing from string format.

vl: Create (most) objects before creating chardev backends
Some types of object must be created before chardevs, other types of
object must be created after chardevs. As such there is no option but
to create objects in two phases.
This takes the decision to create as many object types as possible
right away before anyother backends are created, and only delay
creation of those few which have an explicit dependency on the
chardevs. Hopefully the set which need delaying will remain small
over time.

semihosting: add --semihosting-config arg sub-argument
Add new "arg" sub-argument to the --semihosting-config allowing the user
to pass multiple input arguments separately. It is required for example
by UHI semihosting to construct argc and argv.
Also, update ARM semihosting to support new option (at the moment it is
the only target which cares about arguments).
If the semihosting is enabled and no semihosting args have been specified,
then fall back to -kernel/-append. The -append string is split on whitespace
before initializing semihosting.argv[1..n]; this is different from what
QEMU MIPS machines' pseudo-bootloaders do (i.e. argv[1] contains the whole
-append), but is more intuitive from UHI user's point of view and Linux
kernel just does not care as it concatenates argv[1..n] into single cmdline
string anyway.

target-arm: Add support for Cortex-R5
Introduce a CPU model for the Cortex R5 processor. ARMv7 with MPU,
and both thumb and ARM div instructions.
Also implement dummy ATCM and BTCM. These CPs are defined for R5 but
don't have a lot of meaning in QEMU yet. Raz them so the guest can
proceed if they are read. The TCM registers will return a size of 0,
indicating no TCM.

target-arm: Do not reset sysregs marked as ALIAS
cp_reg_reset() is called from g_hash_table_foreach() which does not
define a specific ordering of the hash table iteration. Thus doing reset
for registers marked as ALIAS would give an ambiguous result when
resetvalue is different for original and alias registers. Exit
cp_reg_reset() early when passed an alias register. Then clean up alias
register definitions from needless resetvalue and resetfn.
In particular, this fixes a bug in the handling of the PMCR register,
which had different resetvalues for its 32 and 64-bit views.

It is common for MMIO registers to overlap, for example a 4 byte register

If these registers are implemented via separate MemoryRegions, it is
wrong to clamp the accesses as the value written would be truncated.
Hence for these regions the effects of commit 23820db (exec: Respect

mc146818rtc: Reset the periodic timer on load
When loading a VM from a snapshot or migration, clock changes can cause
the periodic timer to stall or loop rapidly.
qemu-timer has a reset notifier mechanism that is used to avoid timer
stalls or loops if the host clock changes while the VM is running when
using QEMU_CLOCK_HOST. However, when loading a snapshot or migration,
qemu-timer is initialized and fires the reset notifier before
mc146818rtc is initialized and has registered its reset handler. In
addition, this mechanism isn't used when using QEMU_CLOCK_REALTIME,
which might also change when loading a snapshot or migration.
To correct that problem, this commit resets the periodic timer after
loading from a snapshot or migration if the clock has either jumped
backward or has jumped forward by more than the clock jump limit that
is used by the reset notifier code in qemu-timer.

qemu-timer: Call clock reset notifiers on forward jumps
Commit 691a0c9c introduced a mechanism by which QEMU_CLOCK_HOST can
notify other parts of the emulator when the host clock has jumped
backward. This is used to avoid stalling timers that were scheduled
based on the host clock.
However, if the host clock jumps forward, then timers that were
scheduled based on the host clock may fire rapidly and cause other
problems. For example, the mc146818rtc periodic timer will block
execution of the VM and consume host CPU while firing every interrupt
for the time period that was skipped by the host clock.
To correct that problem, this commit fires the reset notification if the
host clock jumps forward by more than a hard-coded limit. The limit is
currently set to a value of 60 seconds, which should be small enough to
prevent excessive timer loops, but large enough to avoid frequent resets
in idle VMs.

vhost: enable vhost without without MSI-X
We use vhostforce to enable vhost even if Guests don't have MSI-X
support and we fall back to QEMU virtio-net.
This gives a very small performance gain, but the disadvantage
is that guest now controls which virtio code is running
(qemu or vhost) so our attack surface is doubled.
This patch will enable vhost unconditionally whenever it's requested.
For compatibility, enable vhost when vhostforce is set, as well.

pci: Don't register a specialized 'config_write' if default behavior is intended
Few devices have their specialized 'config_write' methods which simply
call 'pci_default_write_config' followed by a 'msix_write_config' or
'msi_write_config' calls, using exact same arguments.
This is unnecessary as 'pci_default_write_config' already invokes
'msi_write_config' and 'msix_write_config'.
Also, since 'pci_default_write_config' is the default 'config_write'
handler, we can simply avoid the registration of these specialized
versions.

i8254: fix out-of-bounds memory access in pit_ioport_read()
Due converting PIO to the new memory read/write api we no longer provide
separate I/O region lenghts for read and write operations. As a result,
reading from PIT Mode/Command register will end with accessing
pit->channels with invalid index.
Fix this by ignoring read from the Mode/Command register.
This is CVE-2015-3214.

qemu-ga: adding vss-[un]install options
Existing command line options include '-s install' and '-s uninstall'.
These options install/uninstall both Windows QEMU GA service

enables guest agent integration with Volume Shadow Service.
This commit introdices new options '-s vss-install' and '-s vss-uninstall',

for registering and unregistering the COM server during MSI installation,

qemu-log: Open file for logging when specified
qemu-log defaults to stderr when there is no '-D' option mentioned on command
line. When '-D' option is specified, we also need to specify '-d' option for it
to use the specified logfile. When using monitor to enable logging this is
troublesome since there will be no '-d' option because of which monitor dumps
the logs to stderr.
Fix this by opening the log file when '-D' is specified on the command line.
Also fix an ancient comment which does not hold true since changing location and
log level has now been streamlined.

We now finally have TCG support for the basic set of instructions necessary
to run the s390-ccw machine. That means in any aspect possible that machine
type is now superior to the legacy s390-virtio machine.
Switch over to the ccw machine as default. That way people don't get a halfway

target-s390x: PER storage-alteration event support
For the PER storage-alteration event we can use the QEMU watchpoint
infrastructure. When PER is enabled or PER control register changed we
enable the corresponding watchpoints. When a watchpoint arises we can
save the event. Unfortunately the current code does not provide the
address space used to trigger the watchpoint. For now we assume it comes
from the default ASC.

translate-all: fix watchpoints if retranslation not possible
The tb_check_watchpoint function currently assumes that all memory
access is done either directly through the TCG code or through an
helper which knows its return address. This is obviously wrong as the
helpers use cpu_ldxx/stxx_data functions to access the memory.
Instead of aborting in that case, don't try to retranslate the code, but
assume that the CPU state (and especially the program counter) has been
saved before calling the helper. Then invalidate the TB based on this
address.

target-s390x: PER instruction-fetch event support
For the PER instruction-fetch, we can't use the QEMU breakpoint
infrastructure as it triggers for a single address and not a full
address range, and as it actually stop before the instruction and
not before.
We therefore call an helper with the just fetched instruction address,
which check if the address is within the PER address range. If it is
the case, an event is recorded and will be signaled through an
exception.
Note that we implement here the PER-3 behaviour, that is an invalid
opcode is not considered as an instruction fetch. Without PER-3 this
behavious is undefined.

target-s390x: PER successful-branching event support
For the PER successful-branching event support, we can't rely on any
QEMU infrastucture. We therefore call an helper in all places where
a branch can be taken. We have to pay attention to the branch to next
case, as it's still a taken branch.
We don't need to care about the cases using goto_tb, as we have disabled
them in the previous patch.

target-s390x: basic PER event handling
This patch add basic support to generate PER exceptions. It adds two
fields to the cpu structure to record for the PER address and PER
code & ATMID values. When an exception is triggered and a PER event is
pending, the two PER values are copied to the lowcore area.
At the end of an instruction, an helper is checking for a possible
pending PER event and triggers an exception in that case. For that to
work with branches, we need to disable TB chaining when PER is
activated. Fortunately it's already in the TB flags.
Finally in case of a SERVICE CALL exception, we need to trigger the PER
exception immediately after.

target-s390x: mvc_fast_memmove: access memory through softmmu
mvc_fast_memmove is bypassing the softmmu functions, getting the
physical source and destination addresses using the mmu_translate
function and accessing the corresponding physical memory. This
prevents watchpoints to work correctly.
Instead use the tlb_vaddr_to_host function to get the host addresses
corresponding to the guest source and destination addresses through the
softmmu code and fallback to the byte level code in case the
corresponding address are not in the QEMU TLB or being examined through
a watchpoint. As a bonus it works even for area crossing pages by
splitting the are into chunks contained in a single page, bringing some
performances improvements. We can therefore remove the 8-byte
loads/stores method, as it is now quite unlikely to be used.
At the same time change the name of the function to fast_memmove as it's
not specific to mvc and use the same argument order as the C memmove
function.

linux-user: ioctl() command type is int
When executing a 64bit target chroot on 64bit host,
the ioctl() command can mismatch.
It seems the previous commit doesn't solve the problem in
my case:
9c6bf9c7 linux-user: Fix ioctl cmd type mismatch on 64-bit targets
For example, a ppc64 chroot on an x86_64 host:
bash-4.3# ls
Unsupported ioctl: cmd=0x80087467
Unsupported ioctl: cmd=0x802c7415
The origin of the problem is in syscall.c:do_ioctl().
static abi_long do_ioctl(int fd, abi_long cmd, abi_long arg)
In this case (ppc64) abi_long is long (on the x86_64), and
cmd = 0x0000000080087467
then
if (ie->target_cmd == cmd)
target_cmd is int, so target_cmd = 0x80087467
and to compare an int with a long, the sign is extended to 64bit,
so the comparison is:
if (0xffffffff80087467 == 0x0000000080087467)
which doesn't match whereas it should.
This patch uses int in the case of the target command type
instead of abi_long.

required by the host. Using the get_user and put_user functions is
the easiest way to handle this and also do the byte-swapping we
require.
(Note that prior to this commit target_to_host_cmsg was incorrectly
using __put_user() rather than __get_user() for the SCM_CREDENTIALS
conversion, which meant it wasn't getting the benefit of the
misalignment handling.)

linux-user: Fix length handling in host_to_target_cmsg
The previous code for handling payload length when converting
cmsg structures from host to target had a number of problems:
* we required the msg->msg_controllen to declare the buffer
to have enough space for final trailing padding (we were
checking against CMSG_SPACE), whereas the kernel does not
require this, and common userspace code assumes this. (In
particular, glibc's "try to talk to nscd" code that it will
run on startup will receive a cmsg with a 4 byte payload and
only allocate 4 bytes for it, which was causing us to do
the wrong thing on architectures that need 8-alignment.)
* we weren't correctly handling the fact that the SO_TIMESTAMP
payload may be larger for the target than the host
* we weren't marking the messages with MSG_CTRUNC when we did
need to truncate a message that wasn't truncated by the host,
but were instead logging a QEMU message; since truncation is
always the result of a guest giving us an insufficiently
sized buffer, we should report it to the guest as the kernel
does and don't log anything
Rewrite the parts of the function that deal with length to
fix these issues, and add a comment in target_to_host_cmsg
to explain why the overflow logging it does is a QEMU bug,
not a guest issue.

target-arm: Correct "preferred return address" for cpreg access exceptions
The architecture defines that when taking an exception trying to
access a coprocessor register, the "preferred return address" for
the exception is the address of the instruction that caused the
exception. Correct an off-by-4 error which meant we were returning
the address after the instruction for traps which happened because
of a failure of a runtime access-check function on an AArch32
register. (Traps caused by translate-time checkable permissions
failures had the correct address, as did traps on AArch64 registers.)

arm: Add has-mpu property
For processors that support MPUs, add a property to de-feature it. This
is similar to the implementation of the EL3 feature.
The processor definition in init sets ARM_FEATURE_MPU if it can support
an MPU. post_init exposes the property, defaulting to true. If cleared
by the instantiator, ARM_FEATURE_MPU is then removed at realize time.
This is to support R profile processors that may or may-not have an MPU
configured.

hw/display/exynos4210_fimd: Fix bit-swapping code
fimd_swap_data() includes code to reverse the bits in a
64-bit integer, but an off-by-one error meant that it would
try to shift off the top of the integer. Correct the bug
(spotted by Coverity).

target-arm: use extended address bits from supersection short descriptor
Since ARMv7 with LPAE support, a supersection short translation table
descriptor has had extended base address fields which hold bits 39:32 of
translated address. These fields are IMPDEF in ARMv6 and ARMv7 without
LPAE support.

target-arm: Handle "extended small page" descriptors correctly
The old ARMv5-style page table format includes a kind of second level
descriptor named the "extended small page" format, whose primary purpose
is to allow specification of the TEX memory attribute bits on a 4K page.
This exists on ARMv6 and also (as an implementation extension) on XScale
CPUs; it's UNPREDICTABLE on v5.
We were mishandling this in two ways:
(1) we weren't implementing it for v6 (probably never noticed because
Linux will use the new-style v6 page table format there)
(2) we were not correctly setting the page_size, which is 4K, not 1K
The latter bug went unnoticed for years because the only thing which
the page_size affects is which TLB entries get flushed when the guest
does a TLB invalidate on an address in the page, and prior to commit
2f0d8631b7 we were doing a full TLB flush very frequently due to Linux's
habit of writing the SCTLR pointlessly a lot.
(We can assume that after commit 2f0d8631b7 the bug went unnoticed
for a year because nobody's actually using the Zaurus/XScale emulation...)
Report the correct page size for these descriptors, and permit them
on ARMv6 CPUs. This fixes a problem where a kernel image for Zaurus
can boot the kernel OK but gets random segfaults when it tries to
run userspace programs.

Starting with version 4.9, GCC assumes it can't safely dereference null
pointers, and uses this for some optimizations. On s390, the lowcore
memory is located at address 0, so this assumption is wrong and breaks
the s390-ccw firmware. Pass -fdelete-null-pointer-checks to avoid that.

Enabling this option just creates a playback buffer with the specified settings,

windows. (The first created stream dictates all other streams settings, at least

linux-user: Allocate thunk size dynamically
We store all struct types in an array of static size without ever
checking whether we overrun it. Of course some day someone (like me
in another, ancient ALSA enabling patch set) will run into the limit
without realizing it.
So let's make the allocation dynamic. We already know the number of
structs that we want to allocate, so we only need to pass the variable
into the respective piece of code.
Also, to ensure we don't accidently overwrite random memory, add some
asserts to sanity check whether a thunk is actually part of our array.

block: Fix reopen flag inheritance
When reopening an image, the block layer already takes care to reopen
bs->file as well with recalculated inherited flags. The same must happen
for any other child (most notably missing before this patch: backing
files).
If bs->file (or any other child) didn't originally inherit from bs, e.g.
because it was created separately and then only referenced, it must not
inherit flags on reopen either, so check the inherited_from field before
propagation the reopen down.
VMDK already reopened its extents manually; this code can now be
dropped.

block: Add BlockDriverState.inherits_from
Currently, the block layer assumes that any block node can have only one
parent, and if it has a parent, that it inherits some options/flags from
this parent.
This is not true any more: With references used in block device
creation, a single node can be used by multiple parents, or it can be
created separately and not inherit flags from any parent.
To handle reopens correctly, a node must know from which parent it
inherited options. This patch adds the information to BlockDriverState.

block: Add list of children to BlockDriverState
This allows iterating over all children of a given BDS, not only
including bs->file and bs->backing_hd, but also driver-specific
ones like VMDK extents or Quorum children.
For bdrv_swap(), the list of children of the swapped BDS stays at that
BDS (because that's where the pointers stay as well). The list head
moves and pointers to it must be fixed up therefore.
The list of children in the parent of the swapped BDS is not affected by
the swap. The contents of the BDS objects is swapped, so the existing
pointer in the parent automatically points to the newly swapped in BDS.

block: Drain requests before swapping nodes in bdrv_swap()
bdrv_swap() requires that there are no requests in flight on either of
the two devices. The request coroutine would work on the wrong
BlockDriverState object (with bs->opaque even being interpreted as a
different type potentially) and all sorts of bad things would result
from this.
The currently existing callers mostly ensure that there is no I/O
pending on nodes that are swapped. In detail, this is:
1. Live snapshots. This goes through qmp_transaction(), which calls
bdrv_drain_all() before doing anything. The command is executed
synchronously, so no new I/O can be issued concurrently.
2. snapshot=on in bdrv_open(). We're in the middle of opening the image
(both the original image and its temporary overlay), so there can't
be any I/O in flight yet.
3. Mirroring. bdrv_drain() is already used on the source device so that
the mirror doesn't miss anything. However, the main loop runs between
that and the bdrv_swap() (which is actually a bug, being addressed in
another series), so there is a small window in which new I/O might be
issued that would be in flight during bdrv_swap().
It is safer to just drain the request queue of both devices in
bdrv_swap() instead of relying on callers to do the right thing.

block: driver should override flags in bdrv_open()
The BDRV_O_PROTOCOL flag should have an impact only if no driver is
specified explicitly. Therefore, if bdrv_open() is called with an
explicit block driver argument (either through the options QDict or
through the drv parameter) and that block driver is a protocol block
driver, BDRV_O_PROTOCOL should be set; if it is a format block driver,
BDRV_O_PROTOCOL should be unset.
While there was code to unset the flag in case a format block driver
has been selected, it only followed the bdrv_fill_options() function
call whereas the flag in fact needs to be adjusted before it is used
there.
With that change, BDRV_O_PROTOCOL will always be set if the BDS should
be a protocol driver; if the driver has been specified explicitly, the
new code will set it; and bdrv_fill_options() will only "probe" a
protocol driver if BDRV_O_PROTOCOL is set. The probing after
bdrv_fill_options() cannot select a protocol driver.
Thus, bdrv_open_image() to open BDS.file is never called if a protocol
BDS is about to be created. With that change in turn it is impossible to
call bdrv_open_common() with a protocol drv and file != NULL, which
allows us to remove the bdrv_swap() call.
This change breaks a test case in qemu-iotest 051:
"-drive file=t.qcow2,file.driver=qcow2" now works because the explicitly
specified "qcow2" overrides the BDRV_O_PROTOCOL which is automatically
set for the "file" BDS (and the filename is just passed down).
Therefore, this patch removes that test case.

raw-posix: Fix .bdrv_co_get_block_status() for unaligned image size
Image files with an unaligned image size have a final hole that starts
at EOF, i.e. in the middle of a sector. Currently, *pnum == 0 is
returned when checking the status of this sector. In qemu-img, this
triggers an assertion failure.
In order to fix this, one type for the sector that contains EOF must be
found. Treating a hole as data is safe, so this patch rounds the
calculated number of data sectors up, so that a partial sector at EOF is
treated as a full data sector.

If a relatively large cluster size is chosen, the default of 1 MB L2
cache is not really appropriate. In this case, unless overridden by the
user, the default cache size should not be determined by its size in
bytes but by the number of L2 tables (clusters) it is supposed to
contain.
Note that without this patch, MIN_L2_CACHE_SIZE will effectively take
over the same role. However, providing space for just two L2 tables is
not enough to be the default.

The principles of the algorithm are simple:

- The active BDS computes if a wait must be done and arms the right
timer.
- If a wait must be done the token timer will be armed so the token
will become the next active BDS.

throttle: Extract timers from ThrottleState into a separate structure
Group throttling will share ThrottleState between multiple bs.
As a consequence the ThrottleState will be accessed by multiple aio
context.
Timers are tied to their aio context so they must go out of the
ThrottleState structure.
This commit paves the way for each bs of a common ThrottleState to
have its own timer.

raw-posix: Fix .bdrv_co_get_block_status() for unaligned image size
Image files with an unaligned image size have a final hole that starts
at EOF, i.e. in the middle of a sector. Currently, *pnum == 0 is
returned when checking the status of this sector. In qemu-img, this
triggers an assertion failure.
In order to fix this, one type for the sector that contains EOF must be
found. Treating a hole as data is safe, so this patch rounds the
calculated number of data sectors up, so that a partial sector at EOF is
treated as a full data sector.
This fixes https://bugzilla.redhat.com/show_bug.cgi?id=1229394

Revert "iothread: release iothread around aio_poll"
This reverts commit a0710f7995f914e3044e5899bd8ff6c43c62f916.
In qemu-devel email message <556DBF87.2020908@de.ibm.com>, Christian
Borntraeger writes:
Having many guests all with a kernel/ramdisk (via -kernel) and
several null block devices will result in hangs. All hanging
guests are in partition detection code waiting for an I/O to return
so very early maybe even the first I/O.
Reverting that commit "fixes" the hangs.
Reverting this commit for the 2.4 release. More time is needed to
investigate and correct this patch.

rocker: bring link up/down on PHY enable/disable
When the OS driver enables/disables the port, go ahead and set the port's
link status to up/down in response to the change. This more closely
emulates real hardware when the PHY for the port is brought up/down
and the PHY negotiates carrier (link status) with link partner. In
the case of qemu, the virtual rocker device can't really do link
negotiation with the link partner as that requires signally over a
physical medium (the wire), so just pretend the negotiation was
successful and bring the link up when the port is enabled.

target-sh4: split out Q and M from of SR and optimize div1
Splitting Q and M out of SR, it's possible to optimize div1 by using
TCG code instead of an helper.
At the same time removed the now unused gen_copy_bit_i32 function.

target-mips: add MTHC0 and MFHC0 instructions
Implement MTHC0 and MFHC0 instructions. In MIPS32 they are used to access
upper word of extended to 64-bits CP0 registers.
In MIPS64, when CP0 destination register specified is the EntryLo0 or
EntryLo1, bits 1:0 of the GPR appear at bits 31:30 of EntryLo0 or
EntryLo1. This is to compensate for RI and XI, which were shifted to bits
63:62 by MTC0 to EntryLo0 or EntryLo1. Therefore creating separate
functions for EntryLo0 and EntryLo1.

target-mips: add CP0.PageGrain.ELPA support
CP0.PageGrain.ELPA enables support for large physical addresses. This field
is encoded as follows:
0: Large physical address support is disabled.
1: Large physical address support is enabled.
If this bit is a 1, the following changes occur to coprocessor 0 registers:
- The PFNX field of the EntryLo0 and EntryLo1 registers is writable and
concatenated with the PFN field to form the full page frame number.
- Access to optional COP0 registers with PA extension, LLAddr, TagLo is
defined.
P5600 can operate in 32-bit or 40-bit Physical Address Mode. Therefore if
XPA is disabled (CP0.PageGrain.ELPA = 0) then assume 32-bit Address Mode.
In MIPS64 assume 36 as default PABITS (when CP0.PageGrain.ELPA = 0).
env->PABITS value is constant and indicates maximum PABITS available on
a core, whereas env->PAMask is calculated from env->PABITS and is also
affected by CP0.PageGrain.ELPA.

Add a protective section footer
Badly formatted migration streams can go undetected or produce
misleading errors due to a lock of checking at the end of sections.
In particular a section that adds an extra 0x00 at the end
causes what looks like a normal end of stream and thus doesn't produce
any errors, and something that ends in a 0x01..0x04 kind of look
like real section headers and then fail when the section parser tries
to figure out which section they are. This is made worse by the
choice of 0x00..0x04 being small numbers that are particularly common
in normal section data.
This patch adds a section footer consisting of a marker (0x7e - ~)
followed by the section-id that was also sent in the header. If
they mismatch then it throws an error explaining which section was
being loaded.

migration: move ram stuff to migration/ram
For historic reasons, ram migration have been on arch_init.c. Just
split it into migration/ram.c, the same that happened with block.c.
There is only code movement, no changes altogether.

nmi: Implement inject_nmi() for non-monitor context use
Let's introduce a general "inject_nmi()" function that doesn't rely on the cpu
index of the monitor, but uses cpu index 0 as default (except for x86).
This function can then later be used from a non-monitor context.

i386/acpi-build: fix PXB workarounds for unsupported BIOSes
The patch
apci: fix PXB behaviour if used with unsupported BIOS
uses the following condition to see if a "PXB mem/IO chunk" has *not* been
configured by the BIOS:
(!range_base || range_base > range_limit)
When this condition evaluates to true, said patch *omits* the
corresponding entry from the _CRS.
Later on the patch checks for the opposite condition (with the intent of
*adding* entries to the _CRS if the "PXB mem/IO chunks" *have* been
configured). Unfortunately, the condition was negated incorrectly: only
the first ! operator was removed, which led to the nonsensical expression
(range_base || range_base > range_limit)
leading to bogus entries in the _CRS, and causing BSOD in Windows Server
2012 R2 when it runs on OVMF.
The correct negative of the condition seen at the top is
(range_base && range_base <= range_limit)
Fix the expressions.

i386/acpi-build: more traditional _UID and _HID for PXB root buses
The ACPI specification permits the _HID and _UID objects to evaluate to
strings. (See "6.1.5 _HID (Hardware ID)" and "6.1.12 _UID (Unique ID)" in
the ACPI v6.0 spec.)
With regard to related standards, the UEFI specification can also express
a device address composed from string _HID and _UID identifiers, inside
the Expanded ACPI Device Path Node. (See "9.3.3 ACPI Device Path", Table
49, in the UEFI v2.5 spec.)
However, numeric (integer) contents for both _HID and _UID are more
traditional. They are recommended by the UEFI spec for size reasons:
[...] the ACPI Device Path node is smaller and should be used if
possible to reduce the size of device paths that may potentially be
stored in nonvolatile storage [...]
External tools support them better (for example the --acpi_hid and
--acpi_uid options of "efibootmgr" only take numeric identifiers).
Finally, numeric _HID and _UID contents are existing practice in the QEMU
source.
This patch was tested with a Fedora 20 LiveCD and a preexistent Windows
Server 2012 R2 guest. Using "acpidump" and "iasl" in the Fedora guest, we
get, in the SSDT:
> Scope (\_SB)
> {
> Device (PC04)
> {
> Name (_UID, 0x04) // _UID: Unique ID
> Name (_HID, EisaId ("PNP0A03") /* PCI Bus */) // _HID: Hardware ID

target-mips: Misaligned memory accesses for R6
Release 6 requires misaligned memory access support for all ordinary memory
access instructions (for example, LW/SW, LWC1/SWC1).
However misaligned support is not provided for certain special memory accesses
such as atomics (for example, LL/SC).

mips_malta: provide ememsize env variable to kernels
Commit 94c2b6aff43c (mips_malta: support up to 2GiB RAM) provided
support for using over 256MB of RAM with the MIPS Malta board, including
capping the memsize variable that QEMUs pseudo-bootloader provides to
the kernel at 256MB in order to match YAMON. It didn't however provide
the ememsize variable which kernels supporting memory outside of the
unmapped address spaces (ie. EVA or highmem) may use to determine the
true size of the RAM present in the system.
Set ememsize to the size of RAM so that such kernels may use all
available memory without the user having to manually specifying its size
& location.

This allows virtio-pci subclasses to change things before the

virtio-pci: correctly set host notifiers for modern bar
Currently, during host notifier set. We only add eventfd for legacy
bar, this is not correct since:
- Non-transitional device does not have legacy bar, so qemu will crash
since proxy->bar was not initialized.
- Modern device uses modern bar and notify cap to notify the device,
we should add eventfd for proxy->notify.
So this patch fixes the above two issues by adding eventfd based on
whether legacy or modern device were supported.

Note that VIRTIO_F_VERSION_1 is technically a transport feature; once
every device is ready for virtio 1.0, we can move setting this

pcnet: force the buffer access to be in bounds during tx
4096 is the maximum length per TMD and it is also currently the size of
the relay buffer pcnet driver uses for sending the packet data to QEMU
for further processing. With packet spanning multiple TMDs it can
happen that the overall packet size will be bigger than sizeof(buffer),
which results in memory corruption.
Fix this by only allowing to queue maximum sizeof(buffer) bytes.
This is CVE-2015-3209.
[Fixed 3-space indentation to QEMU's 4-space coding standard.

bios-tables-test: handle false-positive smbios signature matches
It has been reported that sometimes the .rodata section of SeaBIOS,
containing the constant string against which the SMBIOS signature
ends up being compared, also falls within the guest f-segment. In
that case, the test obviously fails, unless we continue searching
for the *real* SMBIOS entry point.
Rather than stopping at the first match for the SMBIOS signature
("_SM_") in the f-segment (0xF0000-0xFFFFF), continue scanning
until either a valid entry point table is found, or the f-segment
has been exhausted.

collides with a fw_cfg name programmatically added from

tcg: fix dead computation for repeated input arguments
When the same temp is used twice or more as an input argument to a TCG
instruction, the dead computation code doesn't recognize the second use
as a dead temp. This is because the temp is marked as live in the same
loop where dead inputs are checked.
The fix is to split the loop in two parts. This avoid emitting a move
and using a register for the movcond instruction when used as "move if
true" on x86-64. This might bring more improvements on RISC TCG targets
which don't have outputs aliased to inputs.

tcg: fix register allocation with two aliased dead inputs
For TCG ops with two outputs registers (add2, sub2, div2, div2u), when
the same input temp is used for the two inputs aliased to the two
outputs, and when these inputs are both dead, the register allocation
code wrongly assigned the same register to the same output.
This happens for example with sub2 t1, t2, t3, t3, t4, t5, when t3 is
not used anymore after the TCG op. In that case the same register is
used for t1, t2 and t3.
The fix is to look for already allocated aliased input when allocating
a dead aliased input and check that the register is not already
used.

sdl2: fix crash in handle_windowevent() when restoring the screen size
The Ctrl-Alt-u keyboard shortcut restores the screen to its original
size. In the SDL2 UI this is done by destroying the window and
creating a new one. The old window emits SDL_WINDOWEVENT_HIDDEN when
it's destroyed, but trying to call SDL_GetWindowFromID() from that
event's window ID returns a null pointer. handle_windowevent() assumes
that the pointer is never null so it results in a crash.

vhost-user: Improve -netdev/netdev_add/-net/... error reporting
When -netdev vhost-user fails, it first reports a specific error, then
one or more generic ones, like this:
$ qemu-system-x86_64 -netdev vhost-user,id=foo,chardev=xxx
qemu-system-x86_64: -netdev vhost-user,id=foo,chardev=xxx: chardev "xxx" not found
qemu-system-x86_64: -netdev vhost-user,id=foo,chardev=xxx: No suitable chardev found
qemu-system-x86_64: -netdev vhost-user,id=foo,chardev=xxx: Device 'vhost-user' could not be initialized
With the command line, the messages go to stderr. In HMP, they go to
the monitor. In QMP, the last one becomes the error reply, and the
others go to stderr.
Convert net_init_vhost_user() and its helpers to Error. This
suppresses the unwanted unspecific error messages, and makes the
specific error the QMP error reply.

vl: Fail right after first bad -object
Failure to create an object with -object is a fatal error. However,
we delay the actual exit until all -object are processed. On the one
hand, this permits detection of genuine additional errors. On the
other hand, it can muddy the waters with uninteresting additional
errors, e.g. when a later -object tries to reference a prior one that
failed.
We generally stop right on the first bad option, so do that for
-object as well.

machine: Drop use of DEFAULT_RAM_SIZE in help text
As of commit 076b35b5a (machine: add default_ram_size to machine
class) we no longer have a global default ram size, but instead
machine specific defaults. When invoking qemu --help we don't know
which machine you selected, so we can't tell the user the default RAM
size in the help text anymore now.
Thus I don't see an easy way to expose the default ram size to the
user in the help text. The easiest option IMHO is to just drop this
piece of information.

atomics: add explicit compiler fence in __atomic memory barriers
__atomic_thread_fence does not include a compiler barrier; in the
C++11 memory model, fences take effect in combination with other
atomic operations. GCC implements this by making __atomic_load and
__atomic_store access memory as if the pointer was volatile, and
leaves no trace whatsoever of acquire and release fences in the
compiler's intermediate representation.
In QEMU, we want memory barriers to act on all memory, but at the same
time we would like to use __atomic_thread_fence for portability reasons.
Add compiler barriers manually around the __atomic_thread_fence.

q35: implement SMRAM.D_LCK
Once the SMRAM.D_LCK bit has been set by the guest several bits in SMRAM
and ESMRAMC become readonly until the next machine reset. Implement
this by updating the wmask accordingly when the guest sets the lock bit.
As the lock it itself is locked down too we don't need to worry about
the guest clearing the lock bit.

q35: implement high SMRAM
When H_SMRAME is 1, low memory at 0xa0000 is left alone by
SMM, and instead the chipset maps the 0xa0000-0xbffff window at
0xfeda0000-0xfedbffff. This affects both the "non-SMM" view controlled
by D_OPEN and the SMM view controlled by G_SMRAME, so add two new
MemoryRegions and toggle the enabled/disabled state of all four

hw/i386: add a separate region that tracks the SMRAME bit
This region is exported at /machine/smram. It is "empty" if
SMRAME=0 and points to SMRAM if SMRAME=1. The CPU will
enable/disable it as it enters or exits SMRAM.
While touching nearby code, the existing memory region setup was
slightly inconsistent. The smram_region is *disabled* in order to open
SMRAM (because the smram_region shows the low VRAM instead of the RAM
at 0xa0000). Because SMRAM is closed at startup, the smram_region must
be enabled when creating the i440fx or q35 devices.

-global does not work for drivers that have a dot in their name, such as

target-i386: mask NMIs on entry to SMM
QEMU is not blocking NMIs on entry to SMM. Implementing this has to
cover a few corner cases, because:
- NMIs can then be enabled by an IRET instruction and there
is no mechanism to _set_ the "NMIs masked" flag on exit from SMM:
"A special case can occur if an SMI handler nests inside an NMI handler
and then another NMI occurs. [...] When the processor enters SMM while
executing an NMI handler, the processor saves the SMRAM state save map
but does not save the attribute to keep NMI interrupts disabled.
- However, there is some hidden state, because "If NMIs were blocked
before the SMI occurred [and no IRET is executed while in SMM], they
are blocked after execution of RSM." This is represented by the new
HF2_SMM_INSIDE_NMI_MASK bit. If it is zero, NMIs are _unblocked_
on exit from RSM.

While it is obvious that cpu_physical_memory_get_dirty returns true even if

one would expect that it returns true only if all the pages are clean, but
it actually looks for even one clean page. (By contrast, the caller of that

To clarify, rename the function to cpu_physical_memory_all_dirty and return
true if _all_ the pages are dirty. This is the opposite of the previous
meaning, because "all are 1" is the same as "not (any is 0)", so we have to

translate-all: make less of tb_invalidate_phys_page_range depend on is_cpu_write_access
is_cpu_write_access is only set if tb_invalidate_phys_page_range is called
from tb_invalidate_phys_page_fast, and hence from notdirty_mem_write.
However:
- the code bitmap can be built directly in tb_invalidate_phys_page_fast
(unconditionally, since is_cpu_write_access would always be passed as 1);
- the virtual address is not needed to mark the page as "not containing
code" (dirty code bitmap = 1), so we can also remove that use of
is_cpu_write_access. For calls of tb_invalidate_phys_page_range
that do not come from notdirty_mem_write, the next call to
notdirty_mem_write will notice that the page does not contain code
anymore, and will fix up the TLB entry.
The parameter needs to remain in order to guard accesses to cpu->mem_io_pc.

exec: use memory_region_get_dirty_log_mask to optimize dirty tracking
The memory API can now return the exact set of bitmaps that have to
be tracked. Use it instead of the in_migration variable.
In the next patches, we will also use it to set only DIRTY_MEMORY_VGA
or DIRTY_MEMORY_MIGRATION if necessary. This can make a difference
for dataplane, especially after the dirty bitmap is changed to use
more expensive atomic operations.
Of some interest is the change to stl_phys_notdirty. When migration
was introduced, stl_phys_notdirty was changed to effectively behave
as stl_phys during migration. In fact, if one looks at the function as it
was in the beginning (commit 8df1cd0, physical memory access functions,
2005-01-28), at the time the dirty bitmap was the equivalent of
DIRTY_MEMORY_CODE nowadays; hence, the function simply should not touch
the dirty code bits. This patch changes it to do the intended thing.

ram_addr: tweaks to xen_modified_memory
Invoke xen_modified_memory from cpu_physical_memory_set_dirty_range_nocode;
it is akin to DIRTY_MEMORY_MIGRATION, so set it together with that bitmap.
The remaining call from invalidate_and_set_dirty's "else" branch will go
away soon.
Second, fix the second argument to the function in the
cpu_physical_memory_set_dirty_lebitmap call site. That function is only used
by KVM, but it is better to be clean anyway.

kvm: remove special handling of DIRTY_MEMORY_MIGRATION in the dirty log mask
One recent example is commit 4cc856f (kvm-all: Sync dirty-bitmap from
kvm before kvm destroy the corresponding dirty_bitmap, 2015-04-02).
Another performance problem is that KVM keeps tracking dirty pages
after a failed live migration, which causes bad performance due to
disallowing huge page mapping.
Thanks to the previous patch, KVM can now stop hooking into
log_global_start/stop. This simplifies the KVM code noticeably.

memory: include DIRTY_MEMORY_MIGRATION in the dirty log mask
The separate handling of DIRTY_MEMORY_MIGRATION, which does not
call log_start/log_stop callbacks when it changes in a region's
dirty logging mask, has caused several bugs.
One recent example is commit 4cc856f (kvm-all: Sync dirty-bitmap from
kvm before kvm destroy the corresponding dirty_bitmap, 2015-04-02).
Another performance problem is that KVM keeps tracking dirty pages
after a failed live migration, which causes bad performance due to
disallowing huge page mapping.
This patch removes the root cause of the problem by reporting
DIRTY_MEMORY_MIGRATION changes via log_start and log_stop.
Note that we now have to rebuild the FlatView when global dirty
logging is enabled or disabled; this ensures that log_start and
log_stop callbacks are invoked.
This will also be used to make the setting of bitmaps conditional.
In general, this patch lets users of the memory API ignore the
global state of dirty logging if they handle dirty logging
generically per region.

memory: prepare for multiple bits in the dirty log mask
When the dirty log mask will also cover other bits than DIRTY_MEMORY_VGA,
some listeners may be interested in the overall zero/non-zero value of
the dirty log mask; others may be interested in the value of single bits.
For this reason, always call log_start/log_stop if bits have respectively
appeared or disappeared, and pass the old and new values of the dirty log
mask so that listeners can distinguish the kinds of change.
For example, KVM checks if dirty logging used to be completely disabled
(in log_start) or is now completely disabled (in log_stop). On the
other hand, Xen has to check manually if DIRTY_MEMORY_VGA changed,
since that is the only bit it cares about.

memory: differentiate memory_region_is_logging and memory_region_get_dirty_log_mask
For now memory regions only track DIRTY_MEMORY_VGA individually, but
this will change soon. To support this, split memory_region_is_logging
in two functions: one that returns a given bit from dirty_log_mask,
and one that returns the entire mask. memory_region_is_logging gets an
extra parameter so that the compiler flags misuse.
While VGA-specific users (including the Xen listener!) will want to keep
checking that bit, KVM and vhost check for "any bit except migration"
(because migration is handled via the global start/stop listener
callbacks).

Makefile.target: set master BUILD_DIR
make can be invoked in the individual build dirs to build an individual
target or just a single file of a target. e.g.
touch translate-all.c
make -C microblazeel-softmmu translate-all.o
There is however a small bug when using the pixman submodule.
config-host.mak will ref BUILD_DIR for the pixman -I CFLAGS:
grep BUILD_DIR config-host.mak
QEMU_CFLAGS=-I$(SRC_PATH)/pixman/pixman -I$(BUILD_DIR)/pixman/pixman ...
This causes a build failure as -I/pixman/pixman (BUILD_DIR=="") will
not be found.
BUILD_DIR is usually set by the top level Makefile. Just lazy-set it in
Makefile.target to the parent directory.
Granted, this will not work if the pixman submodule is not prebuilt,
but it at least means you can do incremental partial builds once you
have done your initial full build (or attempt) from the top level.
The next step would be refactor make infrastructure to rebuild pixman
on a submake like the one above.

phys_page_set_level is writing zeroes to a struct that has just been

whether to fill in the page "as a leaf" or "as a non-leaf".
memcpy is faster than struct assignment, which copies each bitfield
individually. A compiler bug (https://gcc.gnu.org/PR66391), and
small memcpys like this one are special-cased anyway, and optimized
to a register move, so just use the memcpy.
This cuts the cost of phys_page_set_level from 25% to 5% when

ppc: add helpful message when KVM fails to start VCPU

QEMU aborts with a non explicit error message:

error: kvm run failed Device or resource busy
To help user to diagnose the problem, this patch adds an informative

There is no easy way to check if SMT is enabled before starting the VCPU,
and as this case is the only one setting errno to EBUSY, we just check
the errno value to display a message.

target-s390x: fix MVC instruction when areas overlap
The MVC instruction and the memmove C funtion do not have the same
semantic when memory areas overlap:
MVC: When the operands overlap, the result is obtained as if the
operands were processed one byte at a time and each result byte were
stored immediately after fetching the necessary operand byte.
memmove: Copying takes place as though the bytes in src are first copied
into a temporary array that does not overlap src or dest, and the bytes
are then copied from the temporary array to dest.
The behaviour is therefore the same when the destination is at a lower
address than the source, but not in the other case. This is actually a
trick for propagating a value to an area. While the current code detects
that and call memset in that case, it only does for 1-byte value. This
trick can and is used for propagating two or more bytes to an area.
In the softmmu case, the call to mvc_fast_memmove is correct as the
above tests verify that source and destination are each within a page,
and both in a different page. The part doing the move 8 bytes by 8 bytes
is wrong and we need to check that if the source and destination
overlap, they do with a distance of minimum 8 bytes before copying 8
bytes at a time.
In the user code, we should check check that the destination is at a
lower address than source or than the end of the source is at a lower
address than the destination before calling memmove. In the opposite
case we fallback to the same code as the softmmu one. Note that l
represents (length - 1).

slow because it bypasses the QEMU softmmu TLB and because stb_phys calls
try to invalidate the corresponding memory for each access.
Instead use cpu_ldb_{primary,secondary} for the loads and
cpu_stb_{primary,secondary} for the stores. Ideally this should be
further optimized by a call to memcpy, but that already improves the
boot time of a guest by a factor 1.8.

target-s390x: fix MMU index computation
The cpu_mmu_index function wrongly looks at PSW P bit to determine the
MMU index, while this bit actually only control the use of priviledge
instructions. The addressing mode is detected by looking at the PSW ASC
bits instead.
This used to work more or less correctly up to kernel 3.6 as the kernel
was running in primary space and userland in secondary space. Since
kernel 3.7 the default is to run the kernel in home space and userland
in primary space. While the current QEMU code seems to work it open some
security issues, like accessing the lowcore memory in R/W mode from a
userspace process once it has been accessed by the kernel (it is then
cached by the QEMU TLB).
At the same time change the MMU_USER_IDX value so that it matches the
value used in recent kernels.

target-s390x: fix LOAD MULTIPLE instruction on page boundary
When consecutive memory locations are on page boundary a page fault
might occur when using the LOAD MULTIPLE instruction. In that case real
hardware doesn't load any register.
This is an important detail in case the base register is in the list
of registers to be loaded. If a page fault occurs this register might be
overwritten and when the instruction is later restarted the wrong
base register value is useD.
Fix this by first loading the first and last value from memory, hence
triggering all possible page faults, and then the remaining registers.
This fixes random segmentation faults seen in the guest.

vhost: logs sharing
Currently we allocate one vhost log per vhost device. This is sub
optimal when:
- Guest has several device with vhost as backend
- Guest has multiqueue devices
In the above cases, we can avoid the memory allocation by sharing a
single vhost log among all the vhost devices. This is done through:
- Introducing a new vhost_log structure with refcnt inside.
- Using a global pointer to vhost_log structure that will be used. And
introduce helper to get the log with expected log size and helper to
- drop the refcnt to the old log.
- Each vhost device still keep track of a pointer to the log that was
used.
With above, if no resize happens, all vhost device will share a single
vhost log. During resize, a new vhost_log structure will be allocated
and made for the global pointer. And each vhost devices will drop the
refcnt to the old log.
Tested by doing scp during migration for a 2 queues virtio-net-pci.

hw/acpi: piix4_pm_init(): take fw_cfg object no more
This PIIX4 init function has no more reason to receive a pointer to the
FwCfg object. Remove the parameter from the prototype, and update callers.
As a result, the pc_init1() function no longer needs to save the return
value of pc_memory_init() and xen_load_linux(), which makes it more
similar to pc_q35_init().
The return type & value of pc_memory_init() and xen_load_linux() are not
changed themselves; maybe we'll need their return values sometime later.

hw/acpi: move "etc/system-states" fw_cfg file from PIIX4 to core
The acpi_pm1_cnt_init() core function is responsible for setting up the
register block that will ultimately react to S3 and S4 requests (see
acpi_pm1_cnt_write()). It makes sense to advertise this configuration to
the guest firmware via an easy to parse fw_cfg file (ACPI is too complex
for firmware to parse), and indeed PIIX4 does that. However, since
acpi_pm1_cnt_init() is not specific to PIIX4, neither should be the fw_cfg
file.
This patch makes "etc/system-states" appear on all chipsets modified in
the previous patch, not just PIIX4 (assuming they have fw_cfg at all).

pseries: Enable in-kernel H_LOGICAL_CI_{LOAD, STORE} implementations
qemu currently implements the hypercalls H_LOGICAL_CI_LOAD and
H_LOGICAL_CI_STORE as PAPR extensions. These are used by the SLOF firmware
for IO, because performing cache inhibited MMIO accesses with the MMU off
(real mode) is very awkward on POWER.
This approach breaks when SLOF needs to access IO devices implemented
within KVM instead of in qemu. The simplest example would be virtio-blk
using an iothread, because the iothread / dataplane mechanism relies on
an in-kernel implementation of the virtio queue notification MMIO.
To fix this, an in-kernel implementation of these hypercalls has been made,
(kernel commit 99342cf "kvmppc: Implement H_LOGICAL_CI_{LOAD,STORE} in KVM"
however, the hypercalls still need to be enabled from qemu. This performs
the necessary calls to do so.
It would be nice to provide some warning if we encounter a problematic
device with a kernel which doesn't support the new calls. Unfortunately,
I can't see a way to detect this case which won't either warn in far too
many cases that will probably work, or which is horribly invasive.

instruct us on what types of connectors entries should be generated
for, since descriptions for different connectors may live in

spapr_events: event-scan RTAS interface
We don't actually rely on this interface to surface hotplug events, and
instead rely on the similar-but-interrupt-driven check-exception RTAS
interface used for EPOW events. However, the existence of this interface
is needed to ensure guest kernels initialize the event-reporting
interfaces which will in turn be used by userspace tools to handle these
events, so we implement this interface here.
Since events surfaced by this call are mutually exclusive to those
surfaced via check-exception, we also update the RTAS event queue code
to accept a boolean to mark/filter for events accordingly.
Events of this sort are not currently generated by QEMU, but the interface
has been tested by surfacing hotplug events via event-scan in place
of check-exception.

spapr_events: re-use EPOW event infrastructure for hotplug events
This extends the data structures currently used to report EPOW events to
guests via the check-exception RTAS interfaces to also include event types
for hotplug/unplug events.
This is currently undocumented and being finalized for inclusion in PAPR
specification, but we implement this here as an extension for guest
userspace tools to implement (existing guest kernels simply log these
events via a sysfs interface that's read by rtas_errd, and current
versions of rtas_errd/powerpc-utils already support the use of this
mechanism for initiating hotplug operations).
We also add support for queues of pending RTAS events, since in the
case of hotplug there's chance for multiple events being in-flight
at any point in time.

spapr_rtas: add ibm, configure-connector RTAS interface
This interface is used to fetch an OF device-tree nodes that describes a
newly-attached device to guest. It is called multiple times to walk the
device-tree node and fetch individual properties into a 'workarea'/buffer
provided by the guest.
The device-tree is generated by QEMU and passed to an sPAPRDRConnector during
the initial hotplug operation, and the state of these RTAS calls is tracked by
the sPAPRDRConnector. When the last of these properties is successfully
fetched, we report as special return value to the guest and transition
the device to a 'configured' state on the QEMU/DRC side.
See docs/specs/ppc-spapr-hotplug.txt for a complete description of
this interface.

spapr: add rtas_st_buffer_direct() helper
This is similar to the existing rtas_st_buffer(), but for cases
where the guest is not expecting a length-encoded byte array.
Namely, for calls where a "work area" buffer is used to pass
around arbitrary fields/data.

spapr_rtas: add get-sensor-state RTAS interface
This interface allows a guest to read various platform/device sensors.
initially, we only implement support necessary to support hotplug:
reading of the dr-entity-sense sensor, which communicates the state of
a hotplugged resource/device to the guest (EMPTY/PRESENT/UNUSABLE).

spapr_drc: initial implementation of sPAPRDRConnector device
This device emulates a firmware abstraction used by pSeries guests to
manage hotplug/dynamic-reconfiguration of host-bridges, PCI devices,
memory, and CPUs. It is conceptually similar to an SHPC device,
complete with LED indicators to identify individual slots to physical
physical users and indicate when it is safe to remove a device. In
some cases it is also used to manage virtualized resources, such a
memory, CPUs, and physical-host bridges, which in the case of pSeries
guests are virtualized resources where the physical components are
managed by the host.
Guests communicate with these DR Connectors using RTAS calls,
generally by addressing the unique DRC index associated with a
particular connector for a particular resource. For introspection
purposes we expose this state initially as QOM properties, and
in subsequent patches will introduce the RTAS calls that make use of
it. This constitutes to the 'guest' interface.
On the QEMU side we provide an attach/detach interface to associate
or cleanup a DeviceState with a particular sPAPRDRConnector in
response to hotplug/unplug, respectively. This constitutes the
'physical' interface to the DR Connector.

hw/ppc/spapr: Fix error message when firmware could not be loaded
When specifying a non-existing file with the "-bios" parameter, QEMU
complained that it "could not find LPAR rtas". That's obviously a
copy-n-paste bug from the code which loads the spapr-rtas.bin, it
should complain about a missing firmware file instead.
Additionally the error message was printed with hw_error() - which
also dumps the whole CPU state. However, this does not make much
sense here since the CPU is not running yet and thus the registers
only contain zeroes. So let's use error_report() here instead.
And while we're at it, let's also bail out if the firmware file
had zero length.

spapr_pci: Fix unsafe signed/unsigned comparisons
spapr_pci.c contains a number of expressions of the form (uval == -1) or
(uval != -1), where 'uval' is an unsigned value.
This mostly works in practice, because as long as the width of uval is
greater or equal than that of (int), the -1 will be promoted to the
unsigned type, which is the expected outcome.
However, at least for the cases where uval is uint32_t, this would break
on platforms where sizeof(int) > 4 (and a few such do exist), because then
the uint32_t value would be promoted to the larger int type, and never be
equal to -1.
This patch fixes these errors. The fixes for the (uint32_t) cases are
necessary as described above. I've made similar fixes to (uint64_t) and
(hwaddr) cases. Those are strictly theoretical, since I don't know of any
platforms where sizeof(int) > 8, but hey, it's not that hard so we might
as well be strictly C standard compliant.

hw/pci: introduce PCI Expander Bridge (PXB)
PXB is a "light-weight" host bridge whose purpose is to enable
the main host bridge to support multiple PCI root buses
for pc machines.
As oposed to PCI-2-PCI bridge's secondary bus, PXB's bus
is a primary bus and can be associated with a NUMA node
(different from the main host bridge) allowing the guest OS
to recognize the proximity of a pass-through device to
other resources as RAM and CPUs.
The PXB is composed from:
- A primary PCI bus (can be associated with a NUMA node)
Acts like a normal pci bus and from the functionality point
of view is an "expansion" of the bus behind the
main host bridge.
- A pci-2-pci bridge behind the primary PCI bus where the actual
devices will be attached.
- A host-bridge PCI device
Situated on the bus behind the main host bridge, allows
the BIOS to configure the bus number and IO/mem resources.
It does not have its own config/data register for configuration
cycles, this being handled by the main host bridge.
- A host-bridge sysbus to comply with QEMU current design.

kvm_s390_vcpu_interrupt_pre_save() and

without KVM_CAP_S390_IRQ_STATE. Move the capability check after the
check for saved IRQ state in kvm_s390_vcpu_interrupt_post_load() so that
migration between hosts without KVM_CAP_S390_IRQ_STATE (including save /
restore on the same host) continues to work.

virtio-ccw/migration: Migrate config vector for virtio devices
virtio_ccw_{save|load}_config are missing code to save and restore a vdev's
config_vector value. This causes some virtio devices to become disabled
following a migration.
This patch fixes a bug whereby the qmp/hmp balloon command (virsh setmem)
silently fails to update the guest's available memory because the device was not
properly migrated.
This will break compatibility, but vmstate_s390_cpu was bumped from
version 2 to version 4 between v2.3.0 and v2.4.0 without a compat
handler. Furthermore, there is no production environment yet so
migration is fenced anyway between any relevant version of 2.3 and 2.4.

util: socket: Add missing localaddr and localport option for DGRAM socket
The 'socket_optslist' structure does not contain the 'localaddr' and
'localport' options that are parsed in case you are creating a
'connect' type UDP character device.
I've noticed it happening after commit f43e47dbf6de24db20ec9b588bb6cc762
made qemu abort() after seeing the invalid option.
A minimal reproducer for the case is:
$ qemu-system-x86_64 -chardev udp,id=charrng0,host=127.0.0.1,port=1234,localaddr=,localport=1234
qemu-system-x86_64: -chardev udp,id=charrng0,host=127.0.0.1,port=1234,localaddr=,localport=1234: Invalid parameter 'localaddr'
Aborted (core dumped)
Prior to the commit mentioned above the error would be printed but the
value for localaddr and localport was simply ignored. I did not go
through the code to find out when it was broken.
Add the two fields so that the options can again be parsed correctly and
qemu doesn't abort().

pc: Ensure non-zero CPU ref count after attaching to ICC bus
Setting the parent bus of a device increases its ref count, which we
ultimately want to level out. However it is only safe to do so after the
last reference to the device in local code, as qom-set or similar operations
might decrease the ref count.
Therefore move the object_unref() from pc_new_cpu() into its callers.
The APIC operations on the last CPU in pc_cpus_init() are still potentially
insecure, but that is beyond the scope of this code movement.

fdc: Fix MSR.RQM flag
The RQM bit in MSR should be set whenever the guest is supposed to
access the FIFO, and it should be cleared in all other cases. This is
important so the guest can't continue writing/reading the FIFO beyond
the length that it's suppossed to access (see CVE-2015-3456).
Commit e9077462 fixed the CVE by adding code that avoids the buffer
overflow; however it doesn't correct the wrong behaviour of the floppy
controller which should already have cleared RQM.
Currently, RQM stays set all the time and during all phases while a
command is being processed. This is error-prone because the command has
to explicitly clear the flag if it doesn't need data (and indeed, the
two buggy commands that are the culprits for the CVE just forgot to do
that).
This patch clears RQM immediately as soon as all bytes that are expected
have been received. If the the FIFO is used in the next phase, the flag
has to be set explicitly there.
It also clear RQM after receiving all bytes even if the phase transition
immediately sets it again. While it's technically not necessary at the
moment because the state between clearing and setting RQM is not
observable by the guest, this is more explicit and matches how real
hardware works. It will actually become necessary in qemu once
asynchronous code paths are introduced.
This alone should have been enough to fix the CVE, but now we have two
lines of defense - even better.

hw/arm/virt: add dynamic sysbus device support
Allows sysbus devices to be instantiated from command line by
using -device option. Machvirt creates a platform bus at init.
The dynamic sysbus devices are attached to this platform bus device.
The platform bus device registers a machine init done notifier
whose role will be to bind the dynamic sysbus devices. Indeed
dynamic sysbus devices are created after machine init.
machvirt also registers a notifier that will build the device
tree nodes for the platform bus and its children dynamic sysbus
devices.

hw/arm/boot: arm_load_kernel implemented as a machine init done notifier
Device tree nodes for the platform bus and its children dynamic sysbus
devices are added in a machine init done notifier. To load the dtb once,
after those latter nodes are built and before ROM freeze, the actual
arm_load_kernel existing code is moved into a notifier notify function,
arm_load_kernel_notify. arm_load_kernel now only registers the
corresponding notifier.
Machine files that do not support platform bus stay unchanged. Machine
files willing to support dynamic sysbus devices must call arm_load_kernel
before sysbus-fdt arm_register_platform_bus_fdt_creator to make sure
dynamic sysbus device nodes are integrated in the dtb.

xen/pt: split out calculation of throughable mask in PCI config space handling
This is just to avoid having to adjust that calculation later in
multiple places.
Note that including ->ro_mask in get_throughable_mask()'s calculation
is only an apparent (i.e. benign) behavioral change: For r/o fields it
doesn't matter > whether they get passed through - either the same flag
is also set in emu_mask (then there's no change at all) or the field is
r/o in hardware (and hence a write won't change it anyway).

xen/MSI: don't open-code pass-through of enable bit modifications
Without this the actual XSA-131 fix would cause the enable bit to not
get set anymore (due to the write back getting suppressed there based
on the OR of emu_mask, ro_mask, and res_mask).
Note that the fiddling with the enable bit shouldn't really be done by
qemu, but making this work right (via libxc and the hypervisor) will
require more extensive changes, which can be postponed until after the
security issue got addressed.

xen/MSI-X: limit error messages
Limit error messages resulting from bad guest behavior to avoid allowing
the guest to cause the control domain's disk to fill.
The first message in pci_msix_write() can simply be deleted, as this
is indeed bad guest behavior, but such out of bounds writes don't
really need to be logged.
The second one is more problematic, as there guest behavior may only
appear to be wrong: For one, the old logic didn't take the mask-all bit
into account. And then this shouldn't depend on host device state (i.e.
the host may have masked the entry without the guest having done so).
Plus these writes shouldn't be dropped even when an entry is unmasked.
Instead, if they can't be made take effect right away, they should take
effect on the next unmasking or enabling operation - the specification
explicitly describes such caching behavior. Until we can validly drop
the message (implementing such caching/latching behavior), issue the
message just once per MSI-X table entry.
Note that the log message in pci_msix_read() similar to the one being
removed here is not an issue: "addr" being of unsigned type, and the
maximum size of the MSI-X table being 32k, entry_nr simply can't be
negative and hence the conditonal guarding issuing of the message will
never be true.
This is XSA-130.

xen: properly gate host writes of modified PCI CFG contents
The old logic didn't work as intended when an access spanned multiple
fields (for example a 32-bit access to the location of the MSI Message
Data field with the high 16 bits not being covered by any known field).
Remove it and derive which fields not to write to from the accessed
fields' emulation masks: When they're all ones, there's no point in
doing any host write.
This fixes a secondary issue at once: We obviously shouldn't make any
host write attempt when already the host read failed.

arm_gicv2m: Add GICv2m widget to support MSIs
The ARM GICv2m widget is a little device that handles MSI interrupt
writes to a trigger register and ties them to a range of interrupt lines
wires to the GIC. It has a few status/id registers and the interrupt wires,
and that's about it.
A board instantiates the device by setting the base SPI number and
number SPIs for the frame. The base-spi parameter is indexed in the SPI
number space only, so base-spi == 0, means IRQ number 32. When a device
(the PCI host controller) writes to the trigger register, the payload is
the GIC IRQ number, so we have to subtract 32 from that and then index
into our frame of SPIs.
When instantiating a GICv2m device, tell PCI that we have instantiated
something that can deal with MSIs. We rely on the board actually wiring
up the GICv2m to the PCI host controller.

monitor: Use trad. command interface for HMP pcie_aer_inject_error
All QMP commands use the "new" handler interface (mhandler.cmd_new).
Most HMP commands still use the traditional interface (mhandler.cmd),
but a few use the "new" one. Complicates handle_user_command() for no
gain, so I'm converting these to the traditional interface.
pcie_aer_inject_error's implementation is split into the
hmp_pcie_aer_inject_error() and pcie_aer_inject_error_print(). The
former is a peculiar crossbreed between HMP and QMP handler. On
success, it works like a QMP handler: store QDict through ret_data
parameter, return 0. Printing the QDict is left to
pcie_aer_inject_error_print(). On failure, it works more like an HMP
handler: print error to monitor, return negative number.
To convert to the traditional interface, turn
pcie_aer_inject_error_print() into a command handler wrapping around
hmp_pcie_aer_inject_error(). By convention, this command handler
should be called hmp_pcie_aer_inject_error(), so rename the existing
hmp_pcie_aer_inject_error() to do_pcie_aer_inject_error().

monitor: Drop broken, unused asynchronous command interface
The asynchronous monitor command interface goes back to commit 940cc30
(Jan 2010). Added a third case to command execution. The hope back
then according to the commit message was that all commands get
converted to the asynchronous interface, killing off the other two
cases. Didn't happen.
The initial asynchronous commands balloon and info balloon were
converted back to synchronous long ago (commit 96637bc and d72f32),
with commit messages calling the asynchronous interface "not fully
working" and "deprecated". The only other user went away in commit
3b5704b.
New code generally uses synchronous commands and asynchronous events.
What exactly is still "not fully working" with asynchronous commands?
Well, here's a bug that defeats actual asynchronous use pretty
reliably: the reply's ID is wrong (and has always been wrong) unless
you use the command synchronously! To reproduce, we need an
asynchronous command, so we have to go back before commit 3b5704b.
Run QEMU with spice:
$ qemu-system-x86_64 -nodefaults -S -spice port=5900,disable-ticketing -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 94, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}}
Connect a spice client in another terminal:
$ remote-viewer spice://localhost:5900
Set up a migration destination dummy in a third terminal:
$ socat TCP-LISTEN:12345 STDIO
Now paste the following into the QMP monitor:
{ "execute": "qmp_capabilities", "id": "i0" }
{ "execute": "client_migrate_info", "id": "i1", "arguments": { "protocol": "spice", "hostname": "localhost", "port": 12345 } }
{ "execute": "query-kvm", "id": "i2" }
Produces two replies immediately, one to qmp_capabilities, and one to
query-kvm:
{"return": {}, "id": "i0"}
{"return": {"enabled": false, "present": true}, "id": "i2"}
Both are correct. Two lines of debug output from libspice-server not
shown.
Now EOF socat's standard input to make it close the connection. This
makes the asynchronous client_migrate_info complete. It replies:
{"return": {}}
Bug: "id": "i1" is missing. Two lines of debug output from
libspice-server not shown. Cherry on top: storage for the missing ID
is leaked.
Get rid of this stuff before somebody hurts himself with it.

vhost-user: add multi queue support
Based on patch by Nikolay Nikolaev:
Vhost-user will implement the multi queue support in a similar way
to what vhost already has - a separate thread for each queue.
To enable the multi queue functionality - a new command line parameter
"queues" is introduced for the vhost-user netdev.

virtio: make features 64bit wide
Make features 64bit wide everywhere.
On migration a full 64bit guest_features field is sent if one of the
high bits is set, in addition to the lower 32bit guest_features field
which must stay for compatibility reasons. That way we send the lower
32 feature bits twice, but the code is simpler because we don't have
to split and compose the 64bit features into two 32bit fields.

Extend TPM TIS interface to support TPM 2
Following the recent upgrade to version 1.3, extend the TPM TIS
interface with capabilities introduced for support of a TPM 2.
TPM TIS for TPM 2 introduced the following extensions beyond the
TPM TIS 1.3 (used for TPM 1.2):
- A new 32bit interface Id register was introduced.
- New flags for the status (STS) register were defined.
- New flags for the capability flags were defined.
Support the above if a TPM TIS 1.3 for TPM 2 is used with a TPM 2
on the backend side. Support the old TPM TIS 1.3 configuration if a
TPM 1.2 is being used. A subsequent patch will then determine which
TPM version is being used in the backend.

It is Very annoying to carry forward an outdatEd coNtroller with a mOdern

Hence, let us not instantiate the FDC when all of the following apply:
- the machine type is pc-q35-2.4 or later,
- "-device isa-fdc" is not passed on the command line (nor in the config
file),
- no "-drive if=floppy,..." is requested.

i386/pc_q35: don't insist on board FDC if there's no default floppy
The "no_floppy = 1" machine class setting causes "default_floppy" in
main() to become zero. Consequently, default_drive() will not call
drive_add() and drive_new() for IF_FLOPPY, index=0, meaning that no
default floppy drive will be created for the virtual machine. In that
case, board code should also not insist on the creation of the
board-default FDC.
The board-default FDC will still be created if the user requests a floppy
drive with "-drive if=floppy".
Additionally, separate FDCs can be specified manually with "-device
isa-fdc". They allow the
-device isa-fdc,driveA=...
syntax that is more flexible than the one required by the board-default
FDC:
-global isa-fdc.driveA=...
This patch doesn't change the behavior observably, as all Q35 machine
types have "no_floppy = 0".

Even if board code decides not to request the creation of the FDC (keyed
off board-level factors, to be determined later), we should create the FDC
nevertheless if the user passes '-drive if=floppy' on the command line.
Otherwise '-drive if=floppy' would break without explicit '-device

i386/pc: pc_basic_device_init(): delegate FDC creation request
This patch introduces no observable change, but it allows the callers of
pc_basic_device_init(), ie. pc_init1() and pc_q35_init(), to request (or
not request) the creation of the FDC explicitly.
At the moment both callers pass constant create_fdctrl=true (hence no
observable change).
Assuming a board passes create_fdctrl=false, "floppy" will be NULL on
output, and (beyond the FDC not being created) that NULL will be passed on
to pc_cmos_init(). Luckily, pc_cmos_init() already handles that case.

virtio: move VIRTIO_F_NOTIFY_ON_EMPTY into core
Nearly all transports have been offering VIRTIO_F_NOTIFY_ON_EMPTY,
s390-virtio being the exception. There's no reason why it shouldn't
offer it as well, though (handling is done in core anyway), so let's
move it to the common virtio features.
While we're changing it anyway, fix the indentation for the
DEFINE_VIRTIO_COMMON_FEATURES macro.

pc: acpi: fix pvpanic for buggy guests
In the old times, we always had pvpanic in ACPI and a _STA method told
the guest not to use it. Automatic generation dropped the _STA method
as the specification says that missing _STA means enabled and working.
Some guests (Linux) had buggy drivers and this change made them unable
to utilize pvpanic.
A Linux patch is posted as well, but I think it's worth to make pvpanic
useable on old guests at the price of three lines and few bytes of SSDT.
The old _STA method was
Method (_STA, 0, NotSerialized) {
Store (PEST, Local0)
If (LEqual (Local0, Zero)) {
Return (Zero) }
Else {
Return (0x0F) }}
Igor pointed out that we don't need to use a method to return a constant
and that 0xB (don't show in UI) is the common definition now.
Also, the device used to be PEVT. (PEVT as in "panic event"?)

pc: Define MACHINE_OPTIONS macros consistently for all machines
Define a MACHINE_OPTIONS macro for each PC machine, and move every field
inside the QEMUMachine structs to the macros, except for name, init, and
compat_props.
This also ensures that all MACHINE_OPTIONS inherit the fields from the
next version, so their definitions carry only the changes that exist
between one version and the next one.
Comments about specific cases:
pc-*-2.1:
Existing PC_*_2_1_MACHINE_OPTIONS macros were defined as:
PC_*_MACHINE_OPTIONS,
.default_machine_opts = "firmware=bios-256k.bin"
PC_*_2_2_MACHINE_OPTIONS is:
PC_*_2_3_MACHINE_OPTIONS
which is expanded to:
PC_*_MACHINE_OPTIONS,
.default_machine_opts = "firmware=bios-256k.bin",
.default_display = "std"
The only difference between 2_1 and 2_2 is .default_display, that's why
we didn't reuse PC_*_2_2_MACHINE_OPTIONS. The good news is that having
multiple initializers for a field is allowed by C99, and the last
initializer overrides the previous ones.
So we can reuse the 2_2 macro in 2_1 and define PC_*_2_1_MACHINE_OPTIONS
as:
PC_*_2_2_MACHINE_OPTIONS,
.default_display = NULL
pc-*-1.7:
PC_*_1_7_MACHINE_OPTIONS was defined as:
PC_*_MACHINE_OPTIONS
PC_*_2_0_MACHINE_OPTIONS is defined as:
PC_*_2_1_MACHINE_OPTIONS
which is expanded to:
PC_*_2_2_MACHINE_OPTIONS,
.default_display = NULL
which is expanded to:
PC_*_2_3_MACHINE_OPTIONS,
.default_display = NULL
which is expanded to:
PC_*_MACHINE_OPTIONS,
.default_machine_opts = "firmware=bios-256k.bin",
.default_display = "std",
.default_display = NULL /* overrides the previous line */
So, the only difference between PC_*_1_7_MACHINE_OPTIONS and
PC_*_2_0_MACHINE_OPTIONS is .default_machine_opts (as .default_display
is not explicitly set by PC_*_MACHINE_OPTIONS so it is NULL).
So we can keep the macro reuse pattern and define
PC_*_2_0_MACHINE_OPTIONS as:
PC_*_2_0_MACHINE_OPTIONS,
.default_machine_opts = NULL
pc-*-2.4 (alias and is_default fields):
Set alias and is_default fields inside the 2.4 MACHINE_OPTIONS macro,
and clear it in the 2.3 macro (that reuses the 2.4 macro).
hw_machine:
As all the machines older than v1.0 set hw_version explicitly, we can
safely move the field to the MACHINE_OPTIONS macros without affecting
the other versions that reuse them.
init function:
Some machines had the init function set inside the MACHINE_OPTIONS
macro. Move it to the QEMUMachine declaration, to keep it consistent
with the other machines.

The new variables will now be inherited by pc-0.11 and older, but
pc-0.11 and pc-0.10 already have PCI.rombar=0 on compat_props, so they

madd32_q instructions, does not apply for msub32_q instructions. So remove it.

qapi: add dirty bitmap status
Bitmaps can be in a handful of different states with potentially
more to come as we tool around with migration and persistence patches.
Management applications may need to know why certain bitmaps are
unavailable for various commands, e.g. busy in another operation,
busy being migrated, etc.
Right now, all we offer is BlockDirtyInfo's boolean member 'frozen'.
Instead of adding more booleans, replace it by an enumeration member
'status' with values 'active' and 'frozen'. Then add new value
'disabled'.
Incompatible change. Fine because the changed part hasn't been
released so far.

target-arm: Avoid buffer overrun on UNPREDICTABLE ldrd/strd
A LDRD or STRD where rd is not an even number is UNPREDICTABLE.
We were letting this fall through, which is OK unless rd is 15,
in which case we would attempt to do a load_reg or store_reg
to a nonexistent r16 for the second half of the double-word.
Catch the odd-numbered-rd cases and UNDEF them instead.
To do this we rearrange the structure of the code a little
so we can put the UNDEF catches at the top before we've
allocated TCG temporaries.

the PCIe ranges. Record these ranges in MemMapEntry array, then we could
share and use them for generating ACPI table.

kbd: add brazil kbd keys to qemu
The brazilian computer keyboard layout has two extra keys (compared to
the usual 105-key intl ps/2 keyboard). This patch makes these two keys
known to qemu.
For historic reasons qemu has two ways to specify a key: A QKeyCode
(name-based) or a number (ps/2 scancode based). Therefore we have to
update multiple places to make new keys known to qemu:
(1) The QKeyCode definition in qapi-schema.json
(2) The QKeyCode <-> number mapping table in ui/input-keymap.c
This patch does just that. With this patch applied you can send those
two keys to the guest using the send-key monitor command.

Merge remote-tracking branch 'remotes/cohuck/tags/s390x-20150528' into staging
A set of patches add support for vector registers on s390x.
Notable: Floating point registers and vector registers overlap,
so extra care is needed so that we end up with a consistent state
in all cases.

When migrating a guest, be sure to include the vector registers.
The vector registers are defined in a subsection, similar to the
existing subsection for floating point registers. Since the
floating point registers are always present (and thus migrated),
we can skip them when performing the migration of the vector
registers which may or may not be present.

net/net: Record usage status of mac address
Currently QEMU dynamically generates mac address for the NIC which
doesn't specify the mac address. But when we hotplug a NIC without
specifying mac address, the mac address will increase for the same NIC
along with hotplug and hot-unplug, and at last it will overflow. And if
we codeplug one NIC with mac address e.g. "52:54:00:12:34:56", then
hotplug one NIC without specifying mac address and the mac address of
the hotplugged NIC is duplicate of "52:54:00:12:34:56".
This patch add a mac_table to record the usage status and free the mac
address when the NIC is unrealized.

tap: Improve -netdev/netdev_add/-net/... tap error reporting
When -netdev tap fails, it first reports a specific error, then a
generic one, like this:
$ qemu-system-x86_64 -netdev tap,id=foo
qemu-system-x86_64: -netdev tap,id=foo: could not configure /dev/net/tun: Operation not permitted
qemu-system-x86_64: -netdev tap,id=foo: Device 'tap' could not be initialized
With the command line, the messages go to stderr. In HMP, they go to
the monitor. In QMP, the second one becomes the error reply, and the
first one goes to stderr.
Convert net_init_tap() to Error. This suppresses the unwanted second
message, and makes the specific error the QMP error reply.
[Dropped duplicate "and" from error message as suggested by Eric Blake:
"ifname=, script=, downscript=, and vnet_hdr=, "
"queues=, and vhostfds= are invalid with helper="

tap: Improve -netdev/netdev_add/-net/... bridge error reporting
When -netdev bridge fails, it first reports a specific error, then a
generic one, like this:
$ qemu-system-x86_64 -netdev bridge,id=foo
failed to launch bridge helper
qemu-system-x86_64: -netdev bridge,id=foo: Device 'bridge' could not be initialized
The first message goes to stderr. Wrong for HMP, because errors need
to go to the monitor there.
The second message goes to stderr for -netdev, to the monitor for HMP
netdev_add, and becomes the error reply for QMP netdev_add.
Convert net_bridge_run_helper() to Error, and propagate its errors
through net_init_bridge(). This ensures the error gets reported where
the user is, and suppresses the unwanted second message.
While there, improve the error messages a bit.
The above example becomes:
$ qemu-system-x86_64 -netdev bridge,id=foo
qemu-system-x86_64: -netdev bridge,id=foo: bridge helper failed
net_init_tap() also uses net_bridge_run_helper(). Propagate its
errors there as well. Improves reporting these errors with -netdev
tap & friends.

net: Permit incremental conversion of init functions to Error
Error reporting for netdev_add is broken: the net_client_init_fun[]
report the actual errors with (at best) error_report(), and their
caller net_client_init1() makes up a generic error on top.
For command line and HMP, this produces an mildly ugly error cascade.
In QMP, the actual errors go to stderr, and the generic error becomes
the command's error reply.
To fix this, we need to convert the net_client_init_fun[] to Error.
To permit fixing them one by one, add an Error ** parameter to the
net_client_init_fun[]. If the call fails without returning an Error,
make up the same generic Error as before. But if it returns one, use
that instead. Since none of them does so far, no functional change.

net: Change help text to list -netdev instead of -net by default
Looking at the output of "qemu-system-xxx -help", you easily get
the impression that "-net" is the preferred way instead of "-netdev"
to specify host network interface, since the "-net" option is
omnipresent but the "-netdev" option is only listed as a one-liner
at the end. This is ugly since "-net" is considered as legacy and
even might be removed one day. Thus, this patch switches the output
to explain the host network interfaces with the "-netdev" option
instead, moving the old "-net" option into some few lines at
the end.

ahci: do not remap clb/fis unconditionally
This continues the IOMMU fix from 2.3, where we should not attempt
to remap the CLB or FIS RX buffers if the AHCI device is currently
running.
The same applies to migration: keep our mitts off these registers
unless the device is supposed to be on.
Does not impact backwards compatibility for the AHCI device.

qtest: pre-buffer hex nibs
Instead of converting each byte one-at-a-time and then sending each byte
over the wire, use sprintf() to pre-compute all of the hex nibs into a
single buffer, then send the entire buffer all at once.
This gives a moderate speed boost to memread() and memwrite() functions.

qtest: Add base64 encoded read/write
For larger pieces of data that won't need to be debugged and
viewing the hex nibbles is unlikely to be useful, we can encode
data using base64 instead of encoding each byte as %02x, which
leads to some space savings and faster reads/writes.
For now, the default is left as hex nibbles in memwrite() and memread().
For the purposes of making qtest io easier to read and debug, some
callers may want to specify using the old encoding format for small
patches of data where the savings from base64 wouldn't be that profound.
memwrite/memread use a data encoding that takes 2x the size of the original
buffer, but base64 uses "only" (4/3)x, so for larger buffers we can save a
decent amount of time and space.

qtest: allow arbitrarily long sends
qtest currently has a static buffer of size 1024 that if we
overflow, ignores the additional data silently which leads
to hangs or stream failures.
Use glib's string facilities to allow arbitrarily long data,
but split this off into a new function, qtest_sendf.
Static data can still be sent using qtest_send, which avoids
the malloc/copy overhead.

qtest/ahci: Add migration test
Notes:
* The migration is performed on QOSState objects.
* The migration is performed in such a way that it does not assume
consistency between the allocators attached to each. That is to say,
you can use each QOSState object completely independently and then at
an arbitrary point decide to migrate, and the destination object will
now be consistent with the memory within the source guest. The source
object that was migrated from will have a completely blank allocator.
ahci-test.c:
- verify_state is added
- ahci_migrate is added as a frontend to migrate
- test_migrate_sanity test case is added.

qemu-io: prompt for encryption keys when required
The qemu-io tool does not check if the image is encrypted so
historically would silently corrupt the sectors by writing

commit turns this mistake into a fatal abort, so check for
encryption and prompt for key when required.
This enables us to add unit tests to ensure we don't break

qcow2/qcow: protect against uninitialized encryption key
When a qcow[2] file is opened, if the header reports an
encryption method, this is used to set the 'crypt_method_header'
field on the BDRVQcow[2]State struct, and the 'encrypted' flag
in the BDRVState struct.
When doing I/O operations, the 'crypt_method' field on the
BDRVQcow[2]State struct is checked to determine if encryption
needs to be applied.
The crypt_method_header value is copied into crypt_method when
the bdrv_set_key() method is called.
The QEMU code which opens a block device is expected to always
do a check
if (bdrv_is_encrypted(bs)) {
bdrv_set_key(bs, ....key...);
}
If code forgets to do this, then 'crypt_method' is never set
and so when I/O is performed, QEMU writes plain text data
into a sector which is expected to contain cipher text, or
when reading, will return cipher text instead of plain
text.
Change the qcow[2] code to consult bs->encrypted when deciding
whether encryption is required, and assert(s->crypt_method)
to protect against cases where the caller forgets to set the
encryption key.
Also put an assert in the set_key methods to protect against
the case where the caller sets an encryption key on a block
device that does not have encryption

qemu-iotests: Make debugging python tests easier
Adding "-d" option. The output goes to "tee" so it appears in your
console. Also, raise the verbosity of unnitest runner.
When testing a topic branch, it's possible that a bug introduced by a
code change makes the python test case hang, with debug output, it is
much easier to locate the problem.
This can also be helpful if you want to watch the progress of a python
test, it offers you a way to sense the speed of each test case method
you're writing.
Note: because there is no easy way to get *both* the verbose output and
the output expected by ./check comparison, the case would always fail
with an "output mismatch". The sole purpose of using this option is
giving developers a quick way to debug when things go wrong.

qcow2: use a hash to look for entries in the L2 cache
The current cache algorithm traverses the array starting always from
the beginning, so the average number of comparisons needed to perform
a lookup is proportional to the size of the array.
By using a hash of the offset as the starting point, lookups are
faster and independent from the array size.
The hash is computed using the cluster number of the table, multiplied
by 4 to make it perform better when there are collisions.
In my tests, using a cache with 2048 entries, this reduces the average
number of comparisons per lookup from 430 to 2.5.

qcow2: use an LRU algorithm to replace entries from the L2 cache
The current algorithm to evict entries from the cache gives always
preference to those in the lowest positions. As the size of the cache
increases, the chances of the later elements of being removed decrease
exponentially.
In a scenario with random I/O and lots of cache misses, entries in
positions 8 and higher are rarely (if ever) evicted. This can be seen
even with the default cache size, but with larger caches the problem
becomes more obvious.
Using an LRU algorithm makes the chances of being removed from the
cache independent from the position.

qcow2: use one single memory block for the L2/refcount cache tables
The qcow2 L2/refcount cache contains one separate table for each cache
entry. Doing one allocation per table adds unnecessary overhead and it
also requires us to store the address of each table separately.
Since the size of the cache is constant during its lifetime, it's
better to have an array that contains all the tables using one single
allocation.
In my tests measuring freshly created caches with sizes 128MB (L2) and
32MB (refcount) this uses around 10MB of RAM less.

vmdk: Fix overflow if l1_size is 0x20000000
Richard Jones caught this bug with afl fuzzer.
In fact, that's the only possible value to overflow (extent->l1_size =
0x20000000) l1_size:
l1_size = extent->l1_size * sizeof(long) => 0x80000000;
g_try_malloc returns NULL because l1_size is interpreted as negative
during type casting from 'int' to 'gsize', which yields a enormous
value. Hence, by coincidence, we get a "not too bad" behavior:
qemu-img: Could not open '/tmp/afl6.img': Could not open
'/tmp/afl6.img': Cannot allocate memory
Values larger than 0x20000000 will be refused by the validation in
vmdk_add_extent.
Values smaller than 0x20000000 will not overflow l1_size.

qcow2: Flush pending discards before allocating cluster
Before a freed cluster can be reused, pending discards for this cluster
must be processed.
The original assumption was that this was not a problem because discards
are only cached during discard/write zeroes operations, which are
synchronous so that no concurrent write requests can cause cluster
allocations.
However, the discard/write zeroes operation itself can allocate a new L2
table (and it has to in order to put zero flags there), so make sure we
can cope with the situation.
This fixes https://bugs.launchpad.net/bugs/1349972.

Commit fc3959e466 fixed bdrv_co_write_zeroes which is the common case
for this bug, but it still exists in bdrv_aio_write_zeroes. A simpler
fix would be in bdrv_co_do_pwritev which is the NULL dereference point
and covers both cases.
So don't access it in bdrv_co_do_pwritev in this case, use three aligned
writes.

block: align bounce buffers to page
The following sequence
int fd = open(argv[1], O_RDWR | O_CREAT | O_DIRECT, 0644);
for (i = 0; i < 100000; i++)
write(fd, buf, 4096);
performs 5% better if buf is aligned to 4096 bytes.
The difference is quite reliable.
On the other hand we do not want at the moment to enforce bounce
buffering if guest request is aligned to 512 bytes.
The patch changes default bounce buffer optimal alignment to
MAX(page size, 4k). 4k is chosen as maximal known sector size on real
HDD.
The justification of the performance improve is quite interesting.
From the kernel point of view each request to the disk was split
by two. This could be seen by blktrace like this:
9,0 11 1 0.000000000 11151 Q WS 312737792 + 1023 [qemu-img]
9,0 11 2 0.000007938 11151 Q WS 312738815 + 8 [qemu-img]
9,0 11 3 0.000030735 11151 Q WS 312738823 + 1016 [qemu-img]
9,0 11 4 0.000032482 11151 Q WS 312739839 + 8 [qemu-img]
9,0 11 5 0.000041379 11151 Q WS 312739847 + 1016 [qemu-img]
9,0 11 6 0.000042818 11151 Q WS 312740863 + 8 [qemu-img]
9,0 11 7 0.000051236 11151 Q WS 312740871 + 1017 [qemu-img]
9,0 5 1 0.169071519 11151 Q WS 312741888 + 1023 [qemu-img]
After the patch the pattern becomes normal:
9,0 6 1 0.000000000 12422 Q WS 314834944 + 1024 [qemu-img]
9,0 6 2 0.000038527 12422 Q WS 314835968 + 1024 [qemu-img]
9,0 6 3 0.000072849 12422 Q WS 314836992 + 1024 [qemu-img]
9,0 6 4 0.000106276 12422 Q WS 314838016 + 1024 [qemu-img]
and the amount of requests sent to disk (could be calculated counting
number of lines in the output of blktrace) is reduced about 2 times.
Both qemu-img and qemu-io are affected while qemu-kvm is not. The guest
does his job well and real requests comes properly aligned (to page).

block: minimal bounce buffer alignment
The patch introduces new concept: minimal memory alignment for bounce
buffers. Original so called "optimal" value is actually minimal required
value for aligment. It should be used for validation that the IOVec
is properly aligned and bounce buffer is not required.
Though, from the performance point of view, it would be better if
bounce buffer or IOVec allocated by QEMU will be aligned stricter.
The patch does not change any alignment value yet.

block: return EPERM on writes or discards to read-only devices
This is the behavior in the operating system, for example Linux's
blkdev_write_iter has the following:
if (bdev_read_only(I_BDEV(bd_inode)))
return -EPERM;
This does not apply to opening a device for read/write, when the
device only supports read-only operation. In this case any of
EACCES, EPERM or EROFS is acceptable depending on why writing is
not possible.

configure: Add workaround for ccache and clang
Test if ccache is interfering with semantic analysis of macros,
disable its habit of trying to compile already pre-processed
versions of code if so. ccache attempts to save time by compiling
pre-processed versions of code, but this disturbs clang's static
analysis enough to produce false positives.
ccache allows us to disable this feature, opting instead to
compile the original version instead of its preprocessed version.
This makes ccache much slower for cache misses, but at least it
becomes usable with QEMU/clang.
This workaround only activates for users using ccache AND clang,
and only if their configuration is observed to be producing warnings.
You may need to clear your ccache for builds started without -Werror,
as those may continue to produce warnings from the cache.
Thanks to Peter Eisentraut for his writeup on the issue:

configure: silence glib unknown attribute __alloc_size__
The glib headers use GCC attributes. Unfortunately the __GNUC__ and
__GNUC_MINOR__ version macros are also defined by clang, but clang
doesn't support the same attributes as GCC.
clang 3.5.0 does not support the __alloc_size__ attribute:
https://github.com/llvm-mirror/clang/commit/c047507a9a79e89fc8339e074fa72822a7e7ea73
The following warning is produced:
gstrfuncs.h:257:44: warning: unknown attribute '__alloc_size__' ignored [-Wunknown-attributes]
G_GNUC_MALLOC G_GNUC_ALLOC_SIZE(2);
gmacros.h:67:45: note: expanded from macro 'G_GNUC_ALLOC_SIZE'
#define G_GNUC_ALLOC_SIZE(x) __attribute__((__alloc_size__(x)))
This patch checks whether glib headers cause warnings and disables
-Wunknown-attributes if it is able to.

block/parallels: optimize linear image expansion
Plain image expansion spends a lot of time to update image file size.
This seriously affects the performance. The following simple test
qemu_img create -f parallels -o cluster_size=64k ./1.hds 64G
qemu_io -n -c "write -P 0x11 0 1024M" ./1.hds
could be improved if the format driver will pre-allocate some space
in the image file with a reasonable chunk.
This patch preallocates 128 Mb using bdrv_write_zeroes, which should
normally use fallocate() call inside. Fallback to older truncate()
could be used as a fallback using image open options thanks to the
previous patch.
The benefit is around 15%.

block/parallels: add prealloc-mode and prealloc-size open paramemets
This is preparational commit for tweaks in Parallels image expansion.
The idea is that enlarge via truncate by one data block is slow. It
would be much better to use fallocate via bdrv_write_zeroes and
expand by some significant amount at once.
Original idea with sequential file writing to the end of the file without
fallocate/truncate would be slower than this approach if the image is
expanded with several operations:
- each image expanding means file metadata update, i.e. filesystem
journal write. Truncate/write to newly truncated space update file
metadata twice thus truncate removal helps. With fallocate call
inside bdrv_write_zeroes file metadata is updated only once and
this should happen infrequently thus this approach is the best one
for the image expansion
- tail writes are ordered, i.e. the guest IO queue could not be sent
immediately to the host introducing additional IO delays
This patch just adds proper parameters into BDRVParallelsState and
performs options parsing in parallels_open.

block/parallels: delay writing to BAT till bdrv_co_flush_to_os
The idea is that we do not need to immediately sync BAT to the image as
from the guest point of view there is a possibility that IO is lost
even in the physical controller until flush command was finished.
bdrv_co_flush_to_os is exactly the right place for this purpose.
Technically the patch uses loaded BAT data as a cache and performs
actual on-disk metadata updates in parallels_co_flush_to_os callback.
This patch speed ups
qemu-img create -f parallels -o cluster_size=64k ./1.hds 64G
qemu-io -f parallels -c "write -P 0x11 0 1024k" 1.hds
writing from 50-60 Mb/sec to 80-90 Mb/sec on rotational media and
from 160 Mb/sec to 190 Mb/sec on SSD disk.

block/parallels: implement incorrect close detection
The software driver must set inuse field in Parallels header to
0x746F6E59 when the image is opened in read-write mode. The presence of
this magic in the header on open forces image consistency check.
There is an unfortunate trick here. We can not check for inuse in
parallels_check as this will happen too late. It is possible to do
that for simple check, but during the fix this would always report
an error as the image was opened in BDRV_O_RDWR mode. Thus we save
the flag in BDRVParallelsState for this.
On the other hand, nothing should be done to clear inuse in
parallels_check. Generic close will do the job right.

block/parallels: support parallels image creation
Do not even care to create WithoutFreeSpace image, it is obsolete.
Always create WithouFreSpacExt one.
The code also does not spend a lot of efforts to fill cylinders and
heads fields, they are not used actually in a real life neither in
QEMU nor in Parallels products.

Main approach is taken from qcow2_co_readv.
The patch drops coroutine lock for the duration of IO operation and
peforms normal scatter-gather IO using standard QEMU backend.
The patch also adds comment about locking considerations in the driver.

serial: fix multi-pci card error cleanup.
Put the number of serial ports into a local variable in
multi_serial_pci_realize, then increment the port count
(pci->ports) as we initialize the serial port cores.
Now pci->ports always holds the number of successfully
initialized ports and we can use multi_serial_pci_exit
to properly cleanup the already initialized bits in case
of a init failure.

ui/cocoa: Avoid deprecated NSOKButton/NSCancelButton constants
In OSX 10.10, the NSOKButton and NSCancelButton constants are deprecated
and provoke compiler warnings. Avoid them by using the
NSFileHandlingPanelCancelButton and NSFileHandlingPanelOKButton constants
instead. These are the documented correct constants for the 10.6-and-up
beginSheetModalForWindow API we use. We also use the same method for
the pre-10.6 compatibility code path, but conveniently the constant
values are the same and the constant names have been present since 10.0.
Preferring the constant names that match the non-legacy API makes more
sense anyway.

ui/cocoa: Declare that QemuCocoaAppController implements NSApplicationDelegate
Our class QemuCocoaAppController implements the NSApplicationDelegate
interface, and we pass an object of this class to [NSApp setDelegate].
However, we weren't declaring in the class definition that we implemented
this interface; in OSX 10.10 this provokes the following (slighly
misleading) warning:
ui/cocoa.m:1031:24: warning: sending 'QemuCocoaAppController *' to parameter of
incompatible type 'id<NSFileManagerDelegate>'
[NSApp setDelegate:appController];
^~~~~~~~~~~~~
/System/Library/Frameworks/Foundation.framework/Headers/NSFileManager.h:109:47:
note: passing argument to parameter 'delegate' here
@property (assign) id <NSFileManagerDelegate> delegate NS_AVAILABLE(10_5,
2_0);
^
Annoyingly, this interface wasn't formally defined until OSX 10.6, so we

ui/cocoa: openPanelDidEnd returnCode should be NSInteger, not int
The type for openPanelDidEnd's returnCode argument should be NSInteger,
not int. This only matters for the OSX 10.5 code path where we pass
the method directly to an OSX function to call.

ui/cocoa: Drop tests for CGImageCreateWithImageInRect support
The code that tries to test at both compiletime and runtime
for whether CGImageCreateWithImageInRect is supported provokes
a compile warning on OSX 10.3:
ui/cocoa.m:378:13: warning: comparison of function 'CGImageCreateWithImageInRect'
equal to a null pointer is always false[-Wtautological-pointer-compare]
if (CGImageCreateWithImageInRect == NULL) { // test if "CGImageCreateWithImageInRect" is
supported on host at runtime
^~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~
The simplest way to deal with this is just to drop this code,
since we don't in practice support OSX 10.4 anyway. (10.5 was
released in 2007 and is the last PPC version, so is the earliest
we really need to continue to support at all.)

This patch makes several changes:
- Minimizes distorted full screen display by respecting aspect
ratios.
- Makes full screen mode available on Mac OS 10.7 and higher.
- Allows user to decide if video should be stretched to fill the
screen, using a menu item called "Zoom To Fit".
- Hides the normalWindow so it won't show up in full screen mode.
- Allows user to exit full screen mode.

net: cadence_gem: Split state struct and type into header
Create a new header for Cadence GEM to allow using the device with
modern SoC programming conventions. The state struct needs to be
visible to embed the device in SoC containers.

net: cadence_gem: Clean up variable names
Cleanup some variable names in preparation for migrating the state
struct and type cast macro to a public header. The acronym "GEM" on
its own is not specific enough to be used in a more global namespace
so preface with "cadence". Fix the capitalisation of "gem" in the
state type while touching the typename. Also preface the GEM_MAXREG
macro as this will need to migrate to public header.

qapi: qapi-commands.py option --type is unused, drop it
Anything but --type sync (which is the default) suppresses output
entirely, which makes no sense.
Dates back to the initial commit c17d990. Commit message says
"Currently only generators for synchronous qapi/qmp functions are
supported", so maybe output other than "synchronous qapi/qmp" was
planned at the time, to be selected with --type.
Should other kinds of output ever materialize, we can put the option
back.

qapi: Make c_type() consistently convert qapi names
Continuing the string of cleanups for supporting downstream names
containing '.', this patch focuses on ensuring c_type() can
handle a downstream name. This patch alone does not fix the
places where generator output should be calling this function
but was open-coding things instead, but it gets us a step closer.
In particular, the changes to c_list_type() and type_name() mean
that type_name(FOO) now handles the case when FOO contains '.',
'-', or is a ticklish identifier other than a builtin (builtins
are exempted because ['int'] must remain mapped to 'intList' and
not 'q_intList'). Meanwhile, ['unix'] now maps to 'q_unixList'
rather than 'unixList', to match the fact that 'unix' is ticklish;
however, our naming conventions state that complex types should
start with a capital, so no type name following conventions will
ever have the 'q_' prepended.
Likewise, changes to c_type() mean that c_type(FOO) properly
handles an enum or complex type FOO with '.' or '-' in the
name, or is a ticklish identifier (again, a ticklish identifier
as a type name violates conventions).

qapi: Tidy c_type() logic
c_type() is designed to be called on both string names and on
array designations, so 'name' is a bit misleading because it
operates on more than strings. Also, no caller ever passes
an empty string. Finally, + notation is a bit nicer to read
than '%s' % value for string concatenation.

qapi: Fix C identifiers generated for names containing '.'
c_fun() maps '.' to '_', c_var() doesn't. Nothing prevents '.' in
QAPI names that get passed to c_var().
Which QAPI names get passed to c_fun(), to c_var(), or to both is not
obvious. Names of command parameters and struct type members get
passed to c_var().
c_var() strips a leading '*', but this cannot happen. c_fun()
doesn't.
Fix c_var() to work exactly like c_fun().
Perhaps they should be replaced by a single mapping function.

ICCICR/GICC_CTLR is banked in GICv1 implementations with Security
Extensions or in GICv2 in independent from Security Extensions.
This makes it possible to enable forwarding of interrupts from
the CPU interfaces to the connected processors for Group0 and Group1.
We also allow to set additional bits like AckCtl and FIQEn by changing
the type from bool to uint32. Since the field does not only store the
enable bit anymore and since we are touching the vmstate, we use the
opportunity to rename the field to cpu_ctlr.

hw/intc/arm_gic: Add Interrupt Group Registers
The Interrupt Group Registers allow the guest to configure interrupts
into one of two groups, where Group0 are higher priority and may
be routed to IRQ or FIQ, and Group1 are lower priority and always
routed to IRQ. (In a GIC with the security extensions Group0 is
Secure interrupts and Group 1 is NonSecure.)
The GICv2 always supports interrupt grouping; the GICv1 does only
if it implements the security extensions.
This patch implements the ability to read and write the registers;
the actual functionality the bits control will be added in a
subsequent patch.

armv7m_nvic: systick: Reload the RELOAD value and count down only if ENABLE bit is set
Consider the following pseudo code to configure SYSTICK (The
recommended programming sequence from "the definitive guide to the
arm cortex-m3"):
SYSTICK Reload Value Register = 0xffff
SYSTICK Current Value Register = 0
SYSTICK Control and Status Register = 0x7
The pseudo code "SYSTICK Current Value Register = 0" leads to invoking
systick_reload(). As a consequence, the systick.tick member is updated
and the systick timer starts to count down when the ENABLE bit of
SYSTICK Control and Status Register is cleared.
The worst case is that: during the system initialization, the reset
value of the SYSTICK Control and Status Register is 0x00000000.
When the code "SYSTICK Current Value Register = 0" is executed, the
systick.tick member is accumulated with "(s->systick.reload + 1) *
systick_scale(s)". The systick_scale() gets the external_ref_clock
scale because the CLKSOURCE bit of the SYSTICK Control and Status
Register is cleared. This is the incorrect behavior because of the
code "SYSTICK Control and Status Register = 0x7". Actually, we want
the processor clock instead of the external reference clock.
This incorrect behavior defers the generation of the first interrupt.
The patch fixes the above-mentioned issue by setting the systick.tick
member and modifying the systick timer only if the ENABLE bit of
the SYSTICK Control and Status Register is set.
In addition, the Cortex-M3 Devices Generic User Guide mentioned that
"When ENABLE is set to 1, the counter loads the RELOAD value from the
SYST RVR register and then counts down". This patch adheres to the
statement of the user guide.

rocker: add new rocker switch device
Rocker is a simulated ethernet switch device. The device supports up to 62
front-panel ports and supports L2 switching and L3 routing functions, as well
as L2/L3/L4 ACLs. The device presents a single PCI device for each switch,
with a memory-mapped register space for device driver access.
Rocker device is invoked with -device, for example a 4-port switch:
-device rocker,name=sw1,len-ports=4,ports[0]=dev0,ports[1]=dev1, \
ports[2]=dev2,ports[3]=dev3
Each port is a netdev and can be paired with using -netdev id=<port name>.

rocker: add support for flow modification
We had support for flow add/del. This adds support for flow mod. I needed
this for L3 support where an existing route is modified using NLM_F_REPLACE.
For example:
ip route add 12.0.0.0/30 nexthop via 11.0.0.1 dev swp1
ip route change 12.0.0.0/30 nexthop via 11.0.0.9 dev swp2
The first cmd adds the route. The second cmd changes the existing route by
changing its nexthop info.
In the device, a mod operation results in the matching flow enty being modified
with the new settings. This is atomic to the device.

The QMP is converted from a Python literal to JSON first,

As a side-effect, this JSON output will helpfully show all

Add a special processing mode to craft transactions.
By entering "transaction(" the shell will enter a special

instead of executed as an individual command.
The transaction can be submitted by entering ")" on a line by itself.
Examples:
Separate lines:
(QEMU) transaction(
TRANS> block-dirty-bitmap-add node=drive0 name=bitmap1
TRANS> block-dirty-bitmap-clear node=drive0 name=bitmap0
TRANS> )
With a transaction action included on the first line:
(QEMU) transaction( block-dirty-bitmap-add node=drive0 name=bitmap2
TRANS> block-dirty-bitmap-add node=drive0 name=bitmap3
TRANS> )
As a one-liner, with just one transaction action:
(QEMU) transaction( block-dirty-bitmap-add node=drive0 name=bitmap0 )
As a side-effect of this patch, blank lines are now parsed as no-ops,
regardless of which shell mode you are in.

scripts: qmp-shell: Expand support for QMP expressions
This includes support for [] expressions, single-quotes in
QMP expressions (which is not strictly a part of JSON), and
the ability to use "True", "False" and "None" literals instead
of JSON's equivalent true, false, and null literals.
qmp-shell currently allows you to describe values as
JSON expressions:
key={"key":{"key2":"val"}}
But it does not currently support arrays, which are needed
for serializing and deserializing transactions:
key=[{"type":"drive-backup","data":{...}}]
qmp-shell also only currently accepts doubly quoted strings
as-per JSON spec, but QMP allows single quotes.
Lastly, python allows you to utilize "True" or "False" as
boolean literals, but JSON expects "true" or "false". Expand
qmp-shell to allow the user to type either, converting to the
correct type.
As a consequence of the above, the key=val parsing is also improved
to give better error messages if a key=val token is not provided.
CAVEAT: The parser is still extremely rudimentary and does not
expect to find spaces in {} nor [] expressions. This patch does
not improve this functionality.

to those subsystems. In the last few months he's also doing
pull requests that are a lot more relevant than the ones I

json-parser: Accept 'null' in QMP
We document that in QMP, the client may send any json-value
for the optional "id" key, and then return that same value
on reply (both success and failures, insofar as the failure
happened after parsing the id). [Note that the output may
not be identical to the input, as whitespace may change and
since we may reorder keys within a json-object, but that this
still constitutes the same json-value]. However, we were not
handling the JSON literal null, which counts as a json-value
per RFC 7159.
Also, down the road, given the QAPI schema of {'*foo':'str'} or
{'*foo':'ComplexType'}, we could decide to allow the QMP client
to pass { "foo":null } instead of the current representation of
{ } where omitting the key is the only way to get at the default
NULL value. Such a change might be useful for argument
introspection (if a type in older qemu lacks 'foo' altogether,
then an explicit "foo":null probe will force an easily
distinguished error message for whether the optional "foo" key
is even understood in newer qemu). And if we add default values
to optional arguments, allowing an explicit null would be
required for getting a NULL value associated with an optional
string that has a non-null default. But all that can come at a
later day.
The 'check-unit' testsuite is enhanced to test that parsing
produces the same object as explicitly requesting a reference
to the special qnull object. In addition, I tested with:
$ ./x86_64-softmmu/qemu-system-x86_64 -qmp stdio -nodefaults
{"QMP": {"version": {"qemu": {"micro": 91, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}}
{"execute":"qmp_capabilities","id":null}
{"return": {}, "id": null}
{"id":{"a":null,"b":[1,null]},"execute":"quit"}
{"return": {}, "id": {"a": null, "b": [1, null]}}

qobject: Add a special null QObject
I'm going to fix the JSON parser to recognize null. The obvious
representation of JSON null as (QObject *)NULL doesn't work, because
the parser already uses it as an error value. Perhaps we should
change it to free NULL for null, but that's more than I can do right
now. Create a special null QObject instead.
The existing QDict, QList, and QString all represent something that
is a pointer in C and could therefore be associated with NULL. But
right now, all three of these sub-types are always non-null once
created, so the new null sentinel object is intentionally unrelated
to them.

qobject: Clean up around qtype_code
QTYPE_NONE is a sentinel value. No QObject has this type code.
Document it properly.
Fix dump_qobject() to abort() on QTYPE_NONE, just like for any other
invalid type code.
Fix to_json() to abort() on all invalid type codes, not just
QTYPE_MAX.
Clean up Property member qtype's type: it's a qtype_code.

QJSON: Use OBJECT_CHECK
The QJSON code used casts to (QJSON*) directly, instead of OBJECT_CHECK.
There were even some functions using object_dynamic_cast() calls
followed by assert(), which is exactly what OBJECT_CHECK does (by
calling object_dynamic_cast_assert()).

qemu-nbd: only send a limited number of errno codes on the wire
Right now, NBD includes potentially platform-specific error values in
the wire protocol.
Luckily, most common error values are more or less universal: in
particular, of all errno values <= 34 (up to ERANGE), they are all the
same on supported platforms except for 11 (which is EAGAIN on Windows and
Linux, but EDEADLK on Darwin and the *BSDs). So, in order to guarantee
some portability, only keep a handful of possible error codes and squash
everything else to EINVAL.
This patch defines a limited set of errno values that are valid for the
NBD protocol, and specifies recommendations for what error to return
in specific corner cases. The set of errno values is roughly based on
the errors listed in the read(2) and write(2) man pages, with some
exceptions:
- ENOMEM is added for servers that implement copy-on-write or other
formats that require dynamic allocation.
- EDQUOT is not part of the universal set of errors; it can be changed
to ENOSPC on the wire format.
- EFBIG is part of the universal set of errors, but it is also changed
to ENOSPC because it is pretty similar to ENOSPC or EDQUOT.
Incoming values will in general match system errno values, but not
on the Hurd which has different errno values (they have a "subsystem
code" equal to 0x10 in bits 24-31). The Hurd is probably not something
to which QEMU has been ported, but still do the right thing and
reverse-map the NBD errno values to the system errno values.
The corresponding patch to the NBD protocol description can be found at
http://article.gmane.org/gmane.linux.drivers.nbd.general/3154.

rules.mak: Force CFLAGS for all objects in DSO
Because of the trick of process-archive-undefs, all .mo objects, even
with --enable-modules, are dependencies of executables.
This breaks CFLAGS propogation because the compiling of module object
will happen too early before building for DSO.
With GCC 5, the linking would fail because .o doesn't have -fPIC. Also,
BUILD_DSO will be missed. (module-common.o will have it, so the stamp
symbol was still liked in .so).
Fix the problem by forcing the CFLAGS on individual .o-cflags during
unnest-vars.

#1 0x000055555585f723 in usbnet_can_receive (nc=0x55555641e820) at hw/usb/dev-network.c:1315

#5 0x000055555587dbca in tap_can_send (opaque=0x5555562d7980) at net/tap.c:172
The command to reproduce most reliably was:
qemu-system-i386 -usb -device usb-net,vlan=0 -net tap,vlan=0
This wasn't strictly a problem with tap. Other
networking endpoints (vde, user) could trigger
this problem as well.

s390x/kvm: migrate vcpu interrupt state
This patch adds support to migrate vcpu interrupts.
We use ioctl KVM_S390_GET_IRQ_STATE and _SET_IRQ_STATE

s390x: move fpu regs into a subsection of the vmstate
Let's move the floating point registers into a seperate subsection and

s390x/kvm: use ioctl KVM_S390_IRQ for vcpu interrupts
KVM_S390_INT uses only two parameter fields. This is not
enough to pass all required information for certain interrupts.
A new ioctl KVM_S390_IRQ is available which allows us to
inject all local interrupts as defined in the Principles of
Operation. It takes a struct kvm_s390_irq as a parameter
which can store interrupt payload data for all interrupts.
Let's use the new ioctl for injecting vcpu interrupts.

Let's move operations that are only valid after the backend has been

Also reorder setting up the host feature bits to the sequence used

While we're at it, also add a ->device_unplugged callback to stop
ioeventfd, just to be on the safe side.

virtio-ccw: change realization sequence
virtio-ccw has an odd sequence of realizing devices: first the
device-specific relization (net, block, ...), then the generic
realization. It feels less odd to have the generic realization
callback trigger the device-specific realization instead (and this
also matches what virtio-pci does).
One thing to note: We need to defer initializing the cu model in the
sense id data until after the device-specific realization has been
performed, as we need to refer to the virtio device's device_id.

s390-virtio: use common features
We used to avoid enabling event_idx for virtio-blk devices via
s390-virtio, but we now have a workaround in place for guests trying
to use the device before setting DRIVER_OK. Therefore, let's add
DEFINE_VIRTIO_COMMON_FEATURES to the base device so all devices get
those common features - and make s390-virtio use the same mechanism
as the other transports do.

s390-virtio: Accommodate guests using virtqueues too early
Feature updates are not a synchronuous operation for the legacy
s390-virtio transport. This transport syncs the guest feature bits
(those from finalize) on the set_status hypercall. Before that qemu
thinks that features are zero, which means QEMU will misbehave, e.g.
it will not write the event index, even if the guest asks for it.
Let's detect the case where a kick happens before the driver is ready
and force sync the features.
With this workaround, it is now safe to switch to the common feature
bit handling code as used by all other transports.

qapi: Check for member name conflicts with a base class
Our type inheritance for both 'struct' and for flat 'union' merges
key/value pairs from the base class with those from the type in
question. Although the C code currently boxes things so that there
is a distinction between which member is referred to, the QMP wire
format does not allow passing a key more than once in a single
object. Besides, if we ever change the generated C code to not be
quite so boxy, we'd want to avoid duplicate member names there,
too.
Fix a testsuite entry added in an earlier patch, as well as adding
a couple more tests to ensure we have appropriate coverage. Ensure
that collisions are detected, regardless of whether there is a
difference in opinion on whether the member name is optional.

qapi: Support (subset of) \u escapes in strings
The handling of \ inside QAPI strings was less than ideal, and
really only worked JSON's \/, \\, \", and our extension of \'
(an obvious extension, when you realize we use '' instead of ""
for strings). For other things, like '\n', it resulted in a
literal 'n' instead of a newline.
Of course, at the moment, we really have no use for escaped
characters, as QAPI has to map to C identifiers, and we currently
support ASCII only for that. But down the road, we may add
support for default values for string parameters to a command
or struct; if that happens, it would be nice to correctly support
all JSON escape sequences, such as \n or \uXXXX. This gets us
closer, by supporting Unicode escapes in the ASCII range.
Since JSON does not require \OCTAL or \xXX escapes, and our QMP
implementation does not understand them either, I intentionally
reject it here, but it would be an easy addition if we desired it.
Likewise, intentionally refusing the NUL byte means we don't have
to worry about C strings being shorter than the qapi input.

qapi: Drop tests for inline nested structs
A future patch will be using a 'name':{dictionary} entry in the
QAPI schema to specify a default value for an optional argument;
but existing use of inline nested structs conflicts with that goal.
More precisely, a definition in the QAPI schema associates a name
with a set of properties:
Example 1: { 'struct': 'Foo', 'data': { MEMBERS... } }
associates the global name 'Foo' with properties (meta-type struct)
and MEMBERS...
Example 2: 'mumble': TYPE
within MEMBERS... above associates 'mumble' with properties (type
TYPE) and (optional false) within type Foo
The syntax of example 1 is extensible; if we need another property,
we add another name/value pair to the dictionary (such as
'base':TYPE). The syntax of example 2 is not extensible, because
the right hand side can only be a type.
We have used name encoding to add a property: "'*mumble': 'int'"
associates 'mumble' with (type int) and (optional true). Nice,
but doesn't scale. So the solution is to change our existing uses
to be syntactic sugar to an extensible form:
NAME: TYPE --> NAME: { 'type': TYPE, 'optional': false }
*ONAME: TYPE --> ONAME: { 'type': TYPE, 'optional': true }
This patch fixes the testsuite to avoid inline nested types, by
breaking the nesting into explicit types; it means that the type
is now boxed instead of unboxed in C code, but makes no difference
on the wire (and if desired, a later patch could change the
generator to not do so much boxing in C). When touching code to
add new allocations, also convert existing allocations to
consistently prefer typesafe g_new0 over g_malloc0 when a type
name is involved.

qapi: Merge UserDefTwo and UserDefNested in tests
In the testsuite, UserDefTwo and UserDefNested were identical
structs other than the member names. Reduce code duplication by
having just one type, and choose names that also favor reuse.
This will also make it easier for a later patch to get rid of
inline nested types in QAPI. When touching code related to
allocations, convert g_malloc0(sizeof(Type)) to the more typesafe
g_new0(Type, 1).

'type' embedded in 'data'. Then tweak a couple of tests whose

I also verified that the generated files for QMP and QGA (such

that I didn't leave in any accidental member name changes.

qapi: Prefer 'struct' over 'type' in generator
Referring to "type" as both a meta-type (built-in, enum, union,
alternate, or struct) and a specific type (the name that the
schema uses for declaring structs) is confusing. The confusion
is only made worse by the fact that the generator mostly already
refers to struct even when dealing with expr['type']. This
commit changes the generator to consistently refer to it as
struct everywhere, plus a single back-compat tweak that allows
accepting the existing .json files as-is, so that the meat of
this change is separate from the mindless churn of that change.
Fix the testsuite fallout for error messages that change, and
in some cases, become more legible. Improve comments to better
match our intentions where a struct (rather than any complex
type) is required. Note that in some cases, an error message
now refers to 'struct' while the schema still refers to 'type';
that will be cleaned up in the later commit to the schema.

qapi: More rigorous checking for type safety bypass
Now that we have a way to validate every type, we can also be
stricter about enforcing that callers that want to bypass
type safety in generated code. Prior to this patch, it didn't
matter what value was associated with the key 'gen', but it
looked odd that 'gen':'yes' could result in bypassing the
generated code. These changes also enforce the changes made
earlier in the series for documentation and consolidation of
using '**' as the wildcard type, as well as 'gen':false as the
canonical spelling for requesting type bypass.
Note that 'gen':false is a one-way switch away from the default;
we do not support 'gen':true (similar for 'success-response').
In practice, this doesn't matter.

qapi: Whitelist commands that don't return dictionary
...or an array of dictionaries. Although we have to cater to
existing commands, returning a non-dictionary means the command
is not extensible (no new name/value pairs can be added if more
information must be returned in parallel). By making the
whitelist explicit, any new command that falls foul of this
practice will have to be self-documenting, which will encourage
developers to either justify the action or rework the design to
use a dictionary after all.
It's a little bit sloppy that we share a single whitelist among
three clients (it's too permissive for each). If this is a
problem, a future patch could tighten things by having the
generator take the whitelist as an argument (as in
scripts/qapi-commands.py --legacy-returns=...), or by having
the generator output C code that requires explicit use of the
whitelist (as in:
#ifndef FROBNICATE_LEGACY_RETURN_OK
# error Command 'frobnicate' should return a dictionary
#endif
then having the callers define appropriate macros). But until
we need such fine-grained separation (if ever), this patch does
the job just fine.

qapi: Require valid names
Previous commits demonstrated that the generator overlooked various
bad naming situations:
- types, commands, and events need a valid name
- enum members must be valid names, when combined with prefix
- union and alternate branches cannot be marked optional
Valid upstream names match [a-zA-Z][a-zA-Z0-9_-]*; valid downstream
names match __[a-zA-Z][a-zA-Z0-9._-]*. Enumerations match the
weaker [a-zA-Z0-9._-]+ (in part thanks to QKeyCode picking an enum
that starts with a digit, which we can't change now due to
backwards compatibility). Rather than call out three separate
regex, this patch just uses a broader combination that allows both
upstream and downstream names, as well as a small hack that
realizes that any enum name is merely a suffix to an already valid
name prefix (that is, any enum name is valid if prepending _ fits
the normal rules).
We could reject new enumeration names beginning with a digit by
whitelisting existing exceptions. We could also be stricter
about the distinction between upstream names (no leading
underscore, no use of dot) and downstream (mandatory leading
double underscore), but it is probably not worth the bother.

of command; the 'base': of type and union) must resolve to an

qapi: Add some type check tests
Demonstrate that the qapi generator silently parses confusing

Most of the new tests focus on blatant errors. But
returns-whitelist is a case where we have historically allowed
returning something other than a JSON object from particular
commands; we have to keep that behavior to avoid breaking clients,
but it would be nicer to avoid adding such commands in the future,
because any return that is not an (array of) object cannot be
easily extended if future qemu wants to return additional
information. The QMP protocol already documents that clients
should ignore unknown dictionary keys, but does not require
clients to have to handle more than one type of JSON object.

qapi: Unify type bypass and add tests
For a few QMP commands, we are forced to pass an arbitrary type
without tracking it properly in QAPI. Among the existing clients,
this unnamed type was spelled 'dict', 'visitor', and '**'; this
patch standardizes on '**', matching the documentation changes
earlier in the series.
Meanwhile, for the 'gen' key, we have been ignoring the value,
although the schema consistently used "'no'" ('success-response'
was hard-coded to checking for 'no'). But now that we can support
a literal "false" in the schema, we might as well use that rather
than ignoring the value or special-casing a random string. Note
that these are one-way switches (use of 'gen':true is not the same
as omitting 'gen'). Also, the use of '**' requires 'gen':false,
but the use of 'gen':false does not mandate the use of '**'.
There is no difference to the generated code. Add some tests on
what we'd like to guarantee, although it will take later patches
to clean up test results and actually enforce the use of a bool
parameter.

qapi: Better error messages for duplicated expressions
The previous commit demonstrated that the generator overlooked
duplicate expressions:
- a complex type or command reusing a built-in type name
- redeclaration of a type name, whether by the same or different
metatype
- redeclaration of a command or event
- collision of a type with implicit 'Kind' enum for a union
- collision with an implicit MAX enum constant
Since the c_type() function in the generator treats all names
as being in the same namespace, this patch adds a global array
to track all known names and their source, to prevent collisions
before it can cause further problems. While valid .json files
won't trigger any of these cases, we might as well be nicer to

qapi: Better error messages for bad expressions
The previous commit demonstrated that the generator overlooked some
fairly basic broken expressions:
- missing metataype
- metatype key has a non-string value
- unknown key in relation to the metatype
- conflicting metatype (this patch treats the second metatype as an
unknown key of the first key visited, which is not necessarily the
first key the user typed)
Add check_keys to cover these situations, and update testcases to
match. A couple other tests (enum-missing-data, indented-expr) had
to change since the validation added here occurs so early.
Conversely, changes to ident-with-escape results show that we still
have problems where our handling of escape sequences differs from
true JSON, which will matter down the road if we allow arbitrary
default string values for optional parameters (but for now is not
too bad, as we currently can avoid unicode escaping as we don't
need to represent anything beyond C identifier material).
While valid .json files won't trigger any of these cases, we might
as well be nicer to developers that make a typo while trying to add
new QAPI code.

Note that in some cases, we reject bad QAPI merely because our
pseudo-JSON parser does not yet know how to parse numbers. This
series does not address that, but when a later series adds support
for numeric defaults of integer fields, the testsuite will ensure
that we don't lose the error (and hopefully that the error
message quality is improved).

qapi: Use 'alternate' to replace anonymous union
Previous patches have led up to the point where I create the
new meta-type "'alternate':'Foo'". See the previous patches
for documentation; I intentionally split as much work into
earlier patches to minimize the size of this patch, but a lot
of it is churn due to testsuite fallout after updating to the
new type.

qapi: Document new 'alternate' meta-type
The next patch will quit special-casing "'union':'Foo',
'discriminator':{}" and instead use "'alternate':'Foo'".
Separating docs from implementation makes it easier to focus
on wording without holding up code. In particular, making
alternate a separate type makes for a nice type hierarchy:
/-------- meta-type ------\
/ | \
simple types alternate complex types
| | | |
built-in enum type(struct) union
| \ / / \
numeric string simple flat
A later patch will then clean up 'type' vs. 'struct'
confusion.

qapi: Segregate anonymous unions into alternates in generator
Special-casing 'discriminator == {}' for handling anonymous unions
is getting awkward; since this particular type is not always a
dictionary on the wire, it is easier to treat it as a completely
different class of type, "alternate", so that if a type is listed
in the union_types array, we know it is not an anonymous union.
This patch just further segregates union handling, to make sure that
anonymous unions are not stored in union_types, and splitting up
check_union() into separate functions. A future patch will change
the qapi grammar, and having the segregation already in place will
make it easier to deal with the distinct meta-type.

qapi: Tighten checking of unions
Previous commits demonstrated that the generator had several
flaws with less-than-perfect unions:
- a simple union that listed the same branch twice (or two variant
names that map to the same C enumerator, including the implicit
MAX sentinel) ended up generating invalid C code
- an anonymous union that listed two branches with the same qtype
ended up generating invalid C code
- the generator crashed on anonymous union attempts to use an
array type
- the generator was silently ignoring a base type for anonymous
unions
- the generator allowed unknown types or nested anonymous unions
as a branch in an anonymous union

qapi: Forbid base without discriminator in unions
None of the existing QMP or QGA interfaces uses a union with a
base type but no discriminator; it is easier to avoid this in the
generator to save room for other future extensions more likely to
be useful. An earlier commit added a union-base-no-discriminator
test to ensure that we eventually give a decent error message;
likewise, removing UserDefUnion outright is okay, because we moved
all the tests we wish to keep into the tests of the simple union
UserDefNativeListUnion in the previous commit. Now is the time to
actually forbid simple union with base, and remove the last
vestiges from the testsuite.

qapi: Clean up test coverage of simple unions
The tests of UserDefNativeListUnion serve to validate code
generation of simple unions without a base type, except that it
did not have full coverage in the strict test. The next commits
will remove tests and support for simple unions with a base type,
so there is no real loss at repurposing that test here as
opposed to churn of adding a new test then deleting the old one.
Fix some indentation and long lines while at it.

qapi: Add some union tests
Demonstrate that the qapi generator doesn't deal well with unions
that aren't up to par. Later patches will update the expected
reseults as the generator is made stricter. A few tests work
as planned, but most show poor or missing error messages.
Of particular note, qapi-code-gen.txt documents 'base' only for
flat unions, but the tests here demonstrate that we currently allow
a 'base' to a simple union, although it is exercised only in the
testsuite. Later patches will remove this undocumented feature, to
give us more flexibility in adding other future extensions to union
types. For example, one possible extension is the idea of a
type-safe simple enum, where added fields tie the discriminator to
a user-defined enum type rather than creating an implicit enum from
the names in 'data'. But adding such safety on top of a simple
enum with a base type could look ambiguous with a flat enum;
besides, the documentation also mentions how any simple union can
be represented by an equivalent flat union. So it will be simpler
to just outlaw support for something we aren't using.

qapi: Better error messages for bad enums
The previous commit demonstrated that the generator had several
flaws with less-than-perfect enums:
- an enum that listed the same string twice (or two variant
strings that map to the same C enumerator) ended up generating
an invalid C enum
- because the generator adds a _MAX terminator to each enum,
the use of an enum member 'max' can also cause this clash
- if an enum omits 'data', the generator left a python stack
trace rather than a graceful message
- an enum that used a non-array 'data' was silently accepted by
the parser
- an enum that used non-string members in the 'data' member
was silently accepted by the parser
Add check_enum to cover these situations, and update testcases
to match. While valid .json files won't trigger any of these
cases, we might as well be nicer to developers that make a typo
while trying to add new QAPI code.

that we don't care about Unicode strings, and to just always
use the simpler isinstance(foo, str) everywhere.

qapi: Add copyright declaration on docs
While our top-level COPYING with its GPLv2+ license applies to
any documentation file that omits explicit instructions, these
days it's better to be a good example of calling out our
intentions. Correct use of GPL requires the use of a copyright
statement, so I'm adding notice to two QAPI documents, by
attributing these files to the initial authors and major
contributors. I used:
$ git blame --line-porcelain $file \
| sed -n 's/^author //p' | sort | uniq -c | sort -rn
to determine authorship of these two files. qmp-spec.txt blames
entirely to Red Hat (easy, since my contribution falls in that
category); while qapi-code-gen.txt has multiple contributors
representing multiple entities. But since it was originally
supplied by Michael Roth, the notice I added there copies the
notice he has used in other files. As there is no intended
change in license from the implicit one previously present from
the top level, I have not bothered to CC other contributors;
if we want to weaken things to something looser (such as LGPL)
so that there is no question that someone re-implementing the
spec is not forced to use GPL, that would be a different commit.

Note that using an entire byte for some enums that need less than
that wastes a few bits (noticeable in 32 bits, where we use
20 bytes instead of 16) but avoids extraction code, which overall
is a win--I've tested several variations of the patch, and the appended

apic_common: improve readability of apic_reset_common
Replace call of cpu_is_bsp(s->cpu) which really returns
!!(s->apicbase & MSR_IA32_APICBASE_BSP)
with directly collected value. Due to this the tracepoint
trace_cpu_get_apic_base((uint64_t)s->apicbase);
will not be hit anymore in apic_reset_common.

==17814== Syscall param ioctl(generic) points to uninitialised byte(s)

Enable NVMe start controller for Windows guest.
Windows seems to send two separate calls to NVMe controller configuration. The
first sends configuration info and the second the enable bit. I couldn't
enable the Windows 8.1 in-box NVMe driver with base Qemu. I made the
following change to store the configuration data and then handle enable and
NVMe driver works on Windows 8.1.
I am not a Windows expert and I'm not entirely sure this is the correct
approach. I'm offering it for anyone who wishes to use NVMe on Windows 8.1
using Qemu.
I have tested this change with Linux and Windows guests with NVMe devices.

kvm: better advice for failed s390x startup
If KVM_CREATE failed on s390x, we print a hint to enable the switch_amode
kernel parameter. This only applies to old kernels, and only if the
error was -EINVAL. Moreover, with new kernels, the most likely reason
for -EINVAL is that pgstes were not enabled.
Let's update the error message to give a better hint on where things
may need fixing.

s390x/kvm: Support access register mode for KVM_S390_MEM_OP ioctl
Access register mode is one of the modes that control dynamic address
translation. In this mode the address space is specified by values of
the access registers. The effective address-space-control element is
obtained from the result of the access register translation. See
the "Access-Register Introduction" section of the chapter 5 "Program
Execution" in "Principles of Operations" for more details.
When the CPU is in AR mode, the s390_cpu_virt_mem_rw() function must
know which access register number to use for address translation.
This patch does several things:
- add new parameter 'uint8_t ar' to that function
- decode ar number from intercepted instructions
- pass the ar number to s390_cpu_virt_mem_rw(), which in turn passes it
to the KVM_S390_MEM_OP ioctl.

s390x/kvm: Put vm name, extended name and UUID into STSI322 SYSIB
KVM prefills the SYSIB, returned by STSI 3.2.2. This patch allows
userspace to intercept execution, and fill in the values, that are
known to qemu: machine name (8 chars), extended machine name (256
chars), extended machine name encoding (equals 2 for UTF-8) and UUID.
STSI322 qemu handler also finds a highest virtualization level in
level-3 virtualization stack that doesn't support Extended Names
(Ext Name delimiter) and propagates zero Ext Name to all levels below,
because this level is not capable of managing Extended Names of lower
levels.

nbd/trivial: fix type cast for ioctl
This fixes ioctl behavior on powerpc e6500 platforms with 64bit kernel and 32bit
userspace. The current type cast has no effect there and the value passed to the
kernel is still 0. Probably an issue related to the compiler, since I'm assuming
the same configuration works on a similar setup on x86.
Also ensure consistency with previous type cast in TRACE message.

Makefile.target: prepend $libs_softmmu to $LIBS
I discovered a problem when trying to build QEMU statically with gcc.
libm is an element of LIBS while libpixman-1 is an element in
libs_softmmu. Libpixman references functions in libm, so the original
ordering makes linking fail.
This fix is to reorder $libs_softmmu and $LIBS to make -lm appear after
-lpixman-1. However I'm not quite sure if this is the right fix, hence
the RFC tag.
Normally QEMU is built with c++ compiler which happens to link in libm
(at least this is the case with g++), so building QEMU statically
normally just works and nobody notices this issue.

configure: Add support for tcmalloc
This adds "--enable-tcmalloc" and "--disable-tcmalloc" to allow linking
to libtcmalloc from gperftools.
tcmalloc is a malloc implementation that works well with threads and is
fast, so it is good for performance.
It is disabled by default, because the MALLOC_PERTURB_ flag we use in
tests doesn't work with tcmalloc. However we can enable tcmalloc
specific heap checker and profilers later.
An IOPS gain can be observed with virtio-blk-dataplane, other parts of
QEMU will directly benefit from it as well:

libqtest: add qmp_async
Add qmp_async, which lets us send QMP commands asynchronously.
This is useful when we want to send commands that will trigger
event responses, but we don't know in what order to expect them.
Sometimes the event responses may arrive even before the command
confirmation will show up, so it is convenient to leave the responses
in the stream.

vfio-pci: Reset workaround for AMD Bonaire and Hawaii GPUs
Somehow these GPUs manage not to respond to a PCI bus reset, removing
our primary mechanism for resetting graphics cards. The result is
that these devices typically work well for a single VM boot. If the
VM is rebooted or restarted, the guest driver is not able to init the
card from the dirty state, resulting in a blue screen for Windows
guests.
The workaround is to use a device specific reset. This is not 100%
reliable though since it depends on the incoming state of the device,
but it substantially improves the usability of these devices in a VM.

vfio-pci: Fix error path sign
This is an impossible error path due to the fact that we're reading a
kernel provided, rather than user provided link, which will certainly
always fit in PATH_MAX. Currently it returns a fixed 26 char path
plus %d group number, which typically maxes out at double digits.
However, the caller of the initfn certainly expects a less-than zero
return value on error, not just a non-zero value. Therefore we
should correct the sign here.

vfio-pci: Further fix BAR size overflow
In an analysis by Laszlo, the resulting type of our calculation for
the end of the MSI-X table, and thus the start of memory after the
table, is uint32_t. We're therefore not correctly preventing the
corner case overflow that we intended to fix here where a BAR >=4G
could place the MSI-X table to end exactly at the 4G boundary. The
MSI-X table offset is defined by the hardware spec to 32bits, so we
simply use a cast rather than changing data structure types. This
scenario is purely theoretically, typically the MSI-X table is located
at the front of the BAR.

virtio-scsi: Move DEFINE_VIRTIO_SCSI_FEATURES to virtio-scsi
So far virtio-scsi-device can't expose host features to guest while
using virtio-mmio because it doesn't set DEFINE_VIRTIO_SCSI_FEATURES on
backend or transport.
The host features belong to the backends while virtio-scsi-pci,
virtio-scsi-s390 and virtio-scsi-ccw set the DEFINE_VIRTIO_SCSI_FEATURES
on transports. But they already have the ability to forward property
accesses to the backend child. So if we move the host features to
backends, it doesn't break the backwards compatibility for them and
make host features work while using virtio-mmio.

The error reporting in pci_nic_init() is quite erratic: Some errors
are printed directly with error_report(), and some are passed back
to the caller pci_nic_init_nofail() via an Error pointer.
Since pci_nic_init() is only used by pci_nic_init_nofail(), the
functions can be simply merged to clean up this inconsistency.

iotests: add QMP event waiting queue
A filter is added to allow callers to request very specific
events to be pulled from the event queue, while leaving undesired
events still in the stream.
This allows us to poll for completion data for multiple asynchronous
events in any arbitrary order.
A new timeout context is added to the qmp pull_event method's
wait parameter to allow tests to fail if they do not complete
within some expected period of time.
Also fixed is a bug in qmp.pull_event where we try to retrieve an event
from an empty list if we attempt to retrieve an event with wait=False
but no events have occurred.

- Less than the granularity
- Less than the granularity, but across a boundary
- Less than sizeof(unsigned long)
- Less than sizeof(unsigned long), but across a ulong boundary

block: Add bitmap successors
A bitmap successor is an anonymous BdrvDirtyBitmap that is intended to
be created just prior to a sensitive operation (e.g. Incremental Backup)
that can either succeed or fail, but during the course of which we still
want a bitmap tracking writes.
On creating a successor, we "freeze" the parent bitmap which prevents
its deletion, enabling, anonymization, or creating a bitmap with the
same name.
On success, the parent bitmap can "abdicate" responsibility to the
successor, which will inherit its name. The successor will have been
tracking writes during the course of the backup operation. The parent
will be safely deleted.
On failure, we can "reclaim" the successor from the parent, unifying
them such that the resulting bitmap describes all writes occurring since
the last successful backup, for instance. Reclamation will thaw the
parent, but not explicitly re-enable it.
BdrvDirtyBitmap operations that target a single bitmap are protected
by assertions that the bitmap is not frozen and/or disabled.
BdrvDirtyBitmap operations that target a group of bitmaps, such as
bdrv_{set,reset}_dirty will ignore frozen/disabled drives with a
conditional instead.
Internal functions that enable/disable dirty bitmaps have assertions
added to them to prevent modifying frozen bitmaps.

block: Add bitmap disabled status
Add a status indicating the enabled/disabled state of the bitmap.
A bitmap is by default enabled, but you can lock the bitmap into
a read-only state by setting disabled = true.
A previous version of this patch added a QMP interface for changing
the state of the bitmap, but it has since been removed for now until
a use case emerges where this state must be revealed to the user.
The disabled state WILL be used internally for bitmap migration and
bitmap persistence.

hbitmap: add hbitmap_merge
We add a bitmap merge operation to assist in error cases
where we wish to combine two bitmaps together.
This is algorithmically O(bits) provided HBITMAP_LEVELS remains
constant. For a full bitmap on a 64bit machine:
sum(bits/64^k, k, 0, HBITMAP_LEVELS) ~= 1.01587 * bits
We may be able to improve running speed for particularly sparse
bitmaps by using iterators, but the running time for dense maps
will be worse.
We present the simpler solution first, and we can refine it later
if needed.

qmp: Add block-dirty-bitmap-add and block-dirty-bitmap-remove
The new command pair is added to manage a user created dirty bitmap. The
dirty bitmap's name is mandatory and must be unique for the same device,
but different devices can have bitmaps with the same names.
The granularity is an optional field. If it is not specified, we will
choose a default granularity based on the cluster size if available,
clamped to between 4K and 64K to mirror how the 'mirror' code was
already choosing granularity. If we do not have cluster size info
available, we choose 64K. This code has been factored out into a helper
shared with block/mirror.
This patch also introduces the 'block_dirty_bitmap_lookup' helper,
which takes a device name and a dirty bitmap name and validates the
lookup, returning NULL and setting errp if there is a problem with
either field. This helper will be re-used in future patches in this
series.
The types added to block-core.json will be re-used in future patches
in this series, see:
'qapi: Add transaction support to block-dirty-bitmap-{add, enable, disable}'

qmp: fill in the image field in BlockDeviceInfo
The image field in BlockDeviceInfo is supposed to contain an ImageInfo
object. However that is being filled in by bdrv_query_info(), not by
bdrv_block_device_info(), which is where BlockDeviceInfo is actually
created.
Anyone calling bdrv_block_device_info() directly will get a null image
field. As a consequence of this, the HMP command 'info block -n -v'
crashes QEMU.
This patch moves the code that fills in that field from
bdrv_query_info() to bdrv_block_device_info().

m25p80: add missing blk_attach_dev_nofail
Of the block devices that poked into -drive options via drive_get_next,
m25p80 was the only one who also did not attach itself to the BlockBackend.
Since sd does it, and all other devices go through a "drive" property,
with this change all block backends attached to the guest will have a
non-NULL result for blk_get_attached_dev().

block: avoid unnecessary bottom halves
bdrv_aio_* APIs can use coroutines to achieve asynchronicity. However,
the coroutine may terminate without having yielded back to the caller
(for example because of something that invokes a nested event loop,
or because the coroutine is doing nothing at all). In this case,
the bdrv_aio_* API must delay the completion to the next iteration
of the main loop, because bdrv_aio_* will never invoke the callback
before returning.
This can be done with a bottom half, and indeed bdrv_aio_* is always
using one for simplicity. It is possible to gain some performance
(~3%) by avoiding this in the common case. A new field in the
BlockAIOCBCoroutine struct is set to true until the first time the
corotine has yielded to its creator, and completion goes through a
new function bdrv_co_complete. If the flag is false, bdrv_co_complete
invokes the callback immediately. If it is true, the caller will
notice that the coroutine has completed and schedule the bottom
half itself.

blockjob: Allow nested pause
This patch changes block_job_pause to increase the pause counter and
block_job_resume to decrease it.
The counter will allow calling block_job_pause/block_job_resume
unconditionally on a job when we need to suspend the IO temporarily.
From now on, each block_job_resume must be paired with a block_job_pause
to keep the counter balanced.
The user pause from QMP or HMP will only trigger block_job_pause once
until it's resumed, this is achieved by adding a user_paused flag in
BlockJob.
One occurrence of block_job_resume in mirror_complete is replaced with
block_job_enter which does what is necessary.
In block_job_cancel, the cancel flag is good enough to instruct
coroutines to quit loop, so use block_job_enter to replace the unpaired
block_job_resume.
Upon block job IO error, user is notified about the entering to the
pause state, so this pause belongs to user pause, set the flag
accordingly and expect a matching QMP resume.

qemu-img convert: Rewrite copying logic
The implementation of qemu-img convert is (a) messy, (b) buggy, and
(c) less efficient than possible. The changes required to beat some
sense into it are massive enough that incremental changes would only
make my and the reviewers' life harder. So throw it away and reimplement
it from scratch.
Let me give some examples what I mean by messy, buggy and inefficient:
(a) The copying logic of qemu-img convert has two separate branches for
compressed and normal target images, which roughly do the same -
except for a little code that handles actual differences between
compressed and uncompressed images, and much more code that
implements just a different set of optimisations and bugs. This is
unnecessary code duplication, and makes the code for compressed
output (unsurprisingly) suffer from bitrot.
The code for uncompressed ouput is run twice to count the the total
length for the progress bar. In the first run it just takes a
shortcut and runs only half the loop, and when it's done, it toggles
a boolean, jumps out of the loop with a backwards goto and starts
over. Works, but pretty is something different.
(b) Converting while keeping a backing file (-B option) is broken in
several ways. This includes not writing to the image file if the
input has zero clusters or data filled with zeros (ignoring that the
backing file will be visible instead).
It also doesn't correctly limit every iteration of the copy loop to
sectors of the same status so that too many sectors may be copied to
in the target image. For -B this gives an unexpected result, for
other images it just does more work than necessary.
Conversion with a compressed target completely ignores any target
backing file.
(c) qemu-img convert skips reading and writing an area if it knows from
metadata that copying isn't needed (except for the bug mentioned
above that ignores a status change in some cases). It does, however,
read from the source even if it knows that it will read zeros, and
then search for non-zero bytes in the read buffer, if it's possible
that a write might be needed.
This reimplementation of the copying core reorganises the code to remove
the duplication and have a much more obvious code flow, by essentially
splitting the copy iteration loop into three parts:
1. Find the number of contiguous sectors of the same status at the
current offset (This can also be called in a separate loop before the
copying loop in order to determine the total sectors for the progress
bar.)
2. Read sectors. If the status implies that there is no data there to
read (zero or unallocated cluster), don't do anything.
3. Write sectors depending on the status. If it's data, write it. If
we want the backing file to be visible (with -B), don't write it. If
it's zeroed, skip it if you can, otherwise use bdrv_write_zeroes() to
optimise the write at least where possible.

block: Switch to host monotonic clock for IO throttling
Currently, throttle timers won't make any progress when VCPU is not
running, which would stall the request queue in utils, qtest, vm
suspending, and live migration, without special handling.
Block jobs are confusingly inconsistent between with and without
throttling: if user sets a bps limit, stops the vm, then start a block
job, the block job will not make any progress; in contrary, if user
unsets the bps limit, or if it's not set, the block job will run
normally.
After this patch, with the host clock, even if the VCPUs are stopped,
the throttle queues will be processed.
This patch also enables potential to add throttle to bdrv_drain_all.
Currently all requests are drained immediately. In other words whenever
it is called, IO throttling goes ineffective (examples: system reset,
migration and many block job operations.). This is a loophole that guest
could exploit. If we use the host clock, we can later just trust the
nested poll. This could be done on top.
Note that for qemu-iotests case 093, which uses qtest, we still keep vm
clock so the script can control the clock stepping in order to be
deterministic.

The call sites have been audited to ensure the ffs(0) - 1 == -1 case
never occurs (due to input validation, asserts, etc). Therefore we
don't need to worry about the fact that ctz32(0) == 32.

bt-sdp: fix broken uuids power-of-2 calculation
The binary search in sdp_uuid_match() only works when the number of
elements to search is a power of two.
lo = record->uuid;
hi = record->uuids;
while (hi >>= 1)
if (lo[hi] <= val)
lo += hi;
return *lo == val;
I noticed that the record->uuids calculation in
sdp_service_record_build() was suspect:
record->uuids = 1 << ffs(record->uuids - 1);
Unlike most ffs(val) - 1 users, the expression is ffs(val - 1)!
Actually ffs() is the wrong function to use for power-of-2. Use
pow2ceil() to achieve the correct effect. Now the record->uuid[] array
is sized correctly and the binary search in sdp_uuid_match() should
work.
I'm not sure how to run/test this code.

savevm: create snapshot failed when id_str already exists
The command "virsh create" will fail in such condition: vm has two
disks: vda and vdb. vda has snapshot s1 with id "1", vdb doesn't have
s1 but has snapshot s2 with id "1". When we want to run command "virsh
create s1", del_existing_snapshots() only deletes s1 in vda, and
bdrv_snapshot_create() tries to create vdb's snapshot s1 with id "1",
but id "1" alreay exists in vdb with name "s2"!
The simplest way is call find_new_snapshot_id() unconditionally.

pci: remove hard-coded bar size in msix_init_exclusive_bar()
This patch lets msix_init_exclusive_bar() can calculate the bar and
pba size based on the number of MSI-X vectors other than using a
hard-coded limit 4096. This is needed to allow device to have more
than 128 MSI_X vectors. To keep migration compatibility, keep using
4096 as bar size and 2048 for pba offset.
Notes: We don't care about the case that using vectors > 128 for
legacy machine type. Since we limit the queue max to 64, so vectors >=
65 is meaningless.
Virtio device will be the first user for this.

virtio-pci: speedup MSI-X masking and unmasking
This patch tries to speed up the MSI-X masking and unmasking through
the mapping between vector and queues. With this patch it will there's
no need to go through all possible virtqueues, which may help to
reduce the time spent when doing MSI-X masking/unmasking a single
vector when more than hundreds or even thousands of virtqueues were
supported.
Tested with 80 queue pairs virito-net-pci by changing the smp affinity
in the background and doing netperf in the same time:
Before the patch:
5711.70 Gbits/sec
After the patch:
6830.98 Gbits/sec
About 19.6% improvements in throughput.

virtio: introduce vector to virtqueues mapping
Currently we will try to traverse all virtqueues to find a subset that
using a specific vector. This is sub optimal when we will support
hundreds or even thousands of virtqueues. So this patch introduces a
method which could be used by transport to get all virtqueues that
using a same vector. This is done through QLISTs and the number of
QLISTs was queried through a transport specific method. When guest
setting vectors, the virtqueue will be linked and helpers for traverse
the list was also introduced.
The first user will be virtio pci which will use this to speed up
MSI-X masking and unmasking handling.

vhost-user: Send VHOST_RESET_OWNER on vhost stop
Ensure that the vhost-user slave knows when the vrings are valid and
when they are invalid, for example during a guest reboot.
The vhost-user protocol says this of VHOST_RESET_OWNER:
Issued when a new connection is about to be closed. The Master
will no longer own this connection (and will usually close it).
Send this message to tell the vhost-user slave that the vhost session
has ended and that session state (e.g. vrings) is no longer valid.

ioport: reserve the whole range of an I/O port in the AddressSpace
When an I/O port is more than 1 byte long, ioport.c is currently
creating "short" regions, for example 0x1ce-0x1ce for the 16-bit
Bochs index port. When I/O ports are memory mapped, and thus
accessed via a subpage_ops memory region, subpage_accepts gets
confused because it finds a hole at 0x1cf and rejects the access.
In order to fix this, modify registration of the region to cover
the whole size of the I/O port. Attempts to access an invalid
port will be blocked by find_portio returning NULL.
This only affects the VBE DISPI regions. For all other cases,
the MemoryRegionPortio entries for 2- or 4-byte accesses overlap
an entry for 1-byte accesses, thus the size of the memory region
is not affected.

ioport: loosen assertions on emulation of 16-bit ports
Right now, ioport.c assumes that the entire range specified with
MemoryRegionPortio includes a region with size == 1. This however
is not true for the VBE DISPI ports, which are 16-bit only. The
next patch will make these regions' length equal to two, which can
cause the assertions to trigger. Replace them with simple conditionals.
Also, ioport.c will emulate a 16-bit ioport with two distinct reads
or writes, even if one of the two accesses is out of the bounds given
by the MemoryRegionPortio array. Do not do this anymore, instead
discard writes to the incorrect register and read it as all-ones.
This ensures that the mrp->read and mrp->write callbacks get an
in-range ioport number.

monitor: Make client_migrate_info synchronous
Live migration with spice works like this today:
(1) client_migrate_info monitor cmd
(2) spice server notifies client, client connects to target host.
(3) qemu waits until spice client connect is finished.
(4) send over vmstate (i.e. main part of live migration).
(5) spice handover to target host.
(3) is implemented by making client_migrate_info a async monitor
command. This is the only async monitor command we have.
The original reason to implement this dance was that qemu did not accept
new tcp connections while the incoming migration was running, so (2) and
(4) could not be done in parallel. That issue was fixed long ago though.
Qemu version 1.3.0 (released Dec 2012) and newer happily accept tcp
connects while the incoming migration runs.
Time to drop step (3). This patch does exactly that, by making the
monitor command synchronous and removing the code needed to handle the
async monitor command in ui/spice-core.c

memory: Define API for MemoryRegionOps to take attrs and return status
Define an API so that devices can register MemoryRegionOps whose read
and write callback functions are passed an arbitrary pointer to some
transaction attributes and can return a success-or-failure status code.
This will allow us to model devices which:
* behave differently for ARM Secure/NonSecure memory accesses
* behave differently for privileged/unprivileged accesses
* may return a transaction failure (causing a guest exception)
for erroneous accesses
This patch defines the new API and plumbs the attributes parameter through
to the memory.c public level functions io_mem_read() and io_mem_write(),
where it is currently dummied out.
The success/failure response indication is also propagated out to
io_mem_read() and io_mem_write(), which retain the old-style
boolean true-for-error return.

qmp-commands: fix incorrect uses of ":O" specifier
As far as the QMP parser is concerned, neither the 'O' nor the 'q' format specifiers
put any constraint on the command. However, there are two differences:
1) from a documentation point of view 'O' says that this command takes
a dictionary. The dictionary will be converted to QemuOpts in the
handler to match the corresponding HMP command.
2) 'O' sets QMP_ACCEPT_UNKNOWNS, resulting in the command accepting invalid
extra arguments. For example the following is accepted:
{ "execute": "send-key",
"arguments": { "keys": [ { "type": "qcode", "data": "ctrl" },
{ "type": "qcode", "data": "alt" },
{ "type": "qcode", "data": "delete" } ], "foo": "bar" } }
Neither send-key nor migrate-set-capabilities take a QemuOpts-like
dictionary; they take an array of dictionaries. And neither command
really wants to have extra unknown arguments. Thus, the right
specifier to use in this case is 'q'; with this patch the above
command fails with
{"error": {"class": "GenericError", "desc": "Invalid parameter 'foo'"}}
as intended.

The image field in BlockDeviceInfo should never be null, however
bdrv_block_device_info() is not filling it in.
This makes the 'info block -n -v' command crash QEMU.
The proper solution is probably to move the relevant code from

close to the release for that this simpler workaround solves the
crash.

target-ppc: don't invalidate msr MSR_HVB bit in cpu_post_load
The invalidation code introduced in commit 2360b works by inverting most bits
of env->msr to ensure that hreg_store_msr() will forcibly update the CPU env
state to reflect the new msr value post-migration. Unfortunately
hreg_store_msr() is called with alter_hv set to 0 which preserves the MSR_HVB
state from the CPU env which is now the opposite value to what it should be.
Ensure that we don't invalidate the msr MSR_HVB bit during cpu_post_load so
that the correct value is restored. This fixes suspend/resume for PPC64.

Revert seccomp tests that allow it to be used on non-x86 architectures
Unfortunately it turns out that libseccomp 2.2 still does not work
correctly on non-x86 architectures; return to the previous configure
setup of insisting on libseccomp 2.1 or better and i386/x86_64 and
disabling seccomp support in all other situations.
This reverts the two commits:
* "seccomp: libseccomp version varying according to arch"
(commit 896848f0d3e2393905845ef2b244bb2601f9df0c)

The problem is that pci_nic_init_nofail() does not check whether the err

tcg/tcg-op.c: Fix ld/st of 64 bit values on 32-bit bigendian hosts
Commit 951c6300f7 out-of-lined the 32-bit-host versions of
tcg_gen_{ld,st}_i64, but in the process it inadvertently changed
an #ifdef HOST_WORDS_BIGENDIAN to #ifdef TCG_TARGET_WORDS_BIGENDIAN.
Since the latter doesn't get defined anywhere this meant we always
took the "LE host" codepath, and stored the two halves of the value
in the wrong order on BE hosts. This typically breaks any 64-bit
guest on a 32-bit BE host completely, and will have possibly more
subtle effects even for 32-bit guests.
Switch the ifdef back to HOST_WORDS_BIGENDIAN.

newer libiscsi versions may return zero events from iscsi_which_events.
In this case iscsi_service will return immediately without any progress.
To avoid busy waiting for iscsi_which_events to change we deregister all
read and write handlers in this case and schedule a timer to periodically
check iscsi_which_events for changed events.
Next libiscsi version will introduce async reconnects and zero events
are returned while libiscsi is waiting for a reconnect retry.

aio: strengthen memory barriers for bottom half scheduling
There are two problems with memory barriers in async.c. The fix is
to use atomic_xchg in order to achieve sequential consistency between
the scheduling of a bottom half and the corresponding execution.
First, if bh->scheduled is already 1 in qemu_bh_schedule, QEMU does
not execute a memory barrier to order any writes needed by the callback
before the read of bh->scheduled. If the other side sees req->state as
THREAD_ACTIVE, the callback is not invoked and you get deadlock.
Second, the memory barrier in aio_bh_poll is too weak. Without this
patch, it is possible that bh->scheduled = 0 is not "published" until
after the callback has returned. Another thread wants to schedule the
bottom half, but it sees bh->scheduled = 1 and does nothing. This causes
a lost wakeup. The memory barrier should have been changed to smp_mb()
in commit 924fe12 (aio: fix qemu_bh_schedule() bh->ctx race condition,
2014-06-03) together with qemu_bh_schedule()'s. Guess who reviewed
that patch?
Both of these involve a store and a load, so they are reproducible on
x86_64 as well. It is however much easier on aarch64, where the
libguestfs test suite triggers the bug fairly easily. Even there the
failure can go away or appear depending on compiler optimization level,
tracing options, or even kernel debugging options.
Paul Leveille however reported how to trigger the problem within 15
minutes on x86_64 as well. His (untested) recipe, reproduced here
for reference, is the following:
1) Qcow2 (or 3) is critical – raw files alone seem to avoid the problem.
2) Use “cache=directsync” rather than the default of
“cache=none” to make it happen easier.
3) Use a server with a write-back RAID controller to allow for rapid
IO rates.
4) Run a random-access load that (mostly) writes chunks to various
files on the virtual block device.
a. I use ‘diskload.exe c:25’, a Microsoft HCT load
generator, on Windows VMs.
b. Iometer can probably be configured to generate a similar load.
5) Run multiple VMs in parallel, against the same storage device,
to shake the failure out sooner.
6) IvyBridge and Haswell processors for certain; not sure about others.
A similar patch survived over 12 hours of testing, where an unpatched
QEMU would fail within 15 minutes.
This bug is, most likely, also the cause of failures in the libguestfs
testsuite on AArch64.
Thanks to Laszlo Ersek for initially reporting this bug, to Stefan
Hajnoczi for suggesting closer examination of qemu_bh_schedule, and to
Paul for providing test input and a prototype patch.

virtio-blk: correctly dirty guest memory
After qemu_iovec_destroy, the QEMUIOVector's size is zeroed and
the zero size ultimately is used to compute virtqueue_push's len

migrate their results correctly. (Writes were okay).
Save the size in virtio_blk_handle_request, and use it when the request
is completed.

In recent qemu versions, it is possible to override the backing file
name and format that is stored in the image file with values given at
runtime. In such cases, the temporary override could end up in the
image header if the qcow2 header was updated, while obviously correct
behaviour would be to leave the on-disk backing file path/format
unchanged.

target-i386: kvm: Use env->mcg_cap when setting up MCE
When setting up MCE, instead of using the MCE_*_DEF macros
directly, just filter the existing env->mcg_cap value.
As env->mcg_cap is already initialized as
MCE_CAP_DEF|MCE_BANKS_DEF at target-i386/cpu.c:mce_init(), this
doesn't change any behavior. But it will allow us to change
mce_init() in the future, to implement different defaults
depending on CPU model, machine-type or command-line parameters.

target-i386: kvm: Abort if MCE bank count is not supported by host
Instead of silently changing the number of banks in mcg_cap based
on kvm_get_mce_cap_supported(), abort initialization if the host
doesn't support MCE_BANKS_DEF banks.
Note that MCE_BANKS_DEF was always 10 since it was introduced in
QEMU, and Linux always returned 32 at KVM_CAP_MCE since
KVM_CAP_MCE was introduced, so no behavior is being changed and
the error can't be triggered by any Linux version. The point of
the new check is to ensure we won't silently change the bank
count if we change MCE_BANKS_DEF or make the bank count
configurable in the future.

target-sparc: fix 32-bit truncation in fpackfix
This is reported by Coverity. The algorithm description at
ftp://ftp.icm.edu.pl/packages/ggi/doc/hw/sparc/Sparc.pdf suggests
that the 32-bit parts of rs2, after the left shift, is treated
as a 64-bit integer. Bits 32 and above are used to do the
saturating truncation.

exec: remove warning about mempath and hugetlbfs
The gethugepagesize() method in exec.c printed a warning if
the file path for "-mem-path" or "-object memory-backend-file"
was not on a hugetlbfs filesystem. This warning is bogus, because
QEMU functions perfectly well with the path on a regular tmpfs
filesystem. Use of hugetlbfs vs tmpfs is a choice for the management
application or end user to make as best fits their needs. As such it
is inappropriate for QEMU to have an opinion on whether the user's
choice is right or wrong in this case.

Revert "exec: silence hugetlbfs warning under qtest"
This reverts commit 1c7ba94a184df1eddd589d5400d879568d3e5d08.
That commit changed QEMU initialization order from
- object-initial, chardev, qtest, object-late
to
- chardev, qtest, object-initial, object-late
This breaks chardev setups which need to rely on objects
having been created. For example, when chardevs use TLS
encryption in the future, they need to have tls credential
objects created first.
This revert, restores the ordering introduced in

stop the vm, and do block migration. In this case, we don't drain all

In case of live migration several queues can be enabled and not only the

qjson: Limit number of tokens in addition to total size
Commit 29c75dd "json-streamer: limit the maximum recursion depth and
maximum token count" attempts to guard against excessive heap usage by
limiting total token size (it says "token count", but that's a lie).
Total token size is a rather imprecise predictor of heap usage: many
small tokens use more space than few large tokens with the same input
size, because there's a constant per-token overhead: 37 bytes on my
system.
Tighten this up: limit the token count to 2Mi. Chosen to roughly
match the 64MiB total token size limit.

qjson: surprise, allocating 6 QObjects per token is expensive
Replace the contents of the tokens GQueue with a simple struct. This cuts
the amount of memory allocated by tests/check-qjson from ~500MB to ~20MB,
and the execution time from 600ms to 80ms on my laptop. Still a lot (some
could be saved by using an intrusive list, such as QSIMPLEQ, instead of
the GQueue), but the savings are already massive and the right thing to
do would probably be to get rid of json-streamer completely.

qga: Better mapping of SEEK_* in guest-file-seek
Exposing OS-specific SEEK_ constants in our qapi was a mistake
(if the host has SEEK_CUR as 1, but the guest has it as 2, then
the semantics are unclear what should happen); if we had a time
machine, we would instead expose only a symbolic enum. It's too
late to change the fact that we have an integer in qapi, but we
can at least document what mapping we want to enforce for all
qga clients (and luckily, it happens to be the mapping that both
Linux and Windows use); then fix the code to match that mapping.
It also helps us filter out unsupported SEEK_DATA and SEEK_HOLE.
In the future, we may wish to move our QGA_SEEK_* constants into
qga/qapi-schema.json, along with updating the schema to take an
alternate type (either the integer, or the string value of the
enum name) - but that's too much risk during hard freeze.

According to the specification:
http://pubs.opengroup.org/onlinepubs/9699919799/functions/fopen.html
"the application shall ensure that output is not directly followed by
input without an intervening call to fflush() or to a file positioning
function (fseek(), fsetpos(), or rewind()), and input is not directly
followed by output without an intervening call to a file positioning
function, unless the input operation encounters end-of-file."
Without this change, an fwrite() followed by an fread() may lose the
previously written content, as shown in the following test.

In practice, the timeout if inb() dwarfed the nsleep delays, and as a

makefile: fix qemu-ga make install for --disable-tools
ab59e3e introduced a fix for `make install` on w32 that involved
filtering out qemu-ga from $TOOLS install recipe so that we could
append $(EXESUF) to it before attempting to install the binary
via install-prog function.
install-prog takes a list of binaries to install to a particular
directory. If the list is empty it breaks. We guard against this
by ensuring $TOOLS is not empty prior to calling.
However, ab59e3e introduces extra filtering after this check which
can still result on us attempting to call install-prog with an
empty list of binaries. In particular, this occurs if we
build with the --disable-tools configure option, which results
in qemu-ga being the only member of $TOOLS.
Fix this by doing a simple s/qemu-ga/qemu-ga$(EXESUF)/ pass through
$TOOLS instead of filtering out qemu-ga to handle it seperately.

madvise() returns EINVAL in the case of many failures, but also

Postcopy only really cares that THP is off before it detects faults,

to assume that if the madvise fails then the host just doesn't do
THP and we can carry on with the postcopy.

raw-posix.c: Make GetBSDPath() handle caching options
Add support for caching options that can be specified from the command
line.
The CD-ROM raw char device bypasses the host page cache and therefore
has alignment requirements. Alignment probing is necessary so only use
the raw char device if BDRV_O_NOCACHE is set.

One test case closed an event notifier (event_notifier_cleanup())

resulted in a leftover handle 0 that was added to each subsequent

vhost-user: clarify start and enable
It seems that we currently have some duplication between

The actual reason is that enable is not documented correctly:
what it does is connecting ring to the backend.
This is important for MQ, because a Linux guest expects TX
packets to be completed even if it disables some queues
temporarily.

osdep: Change default value of qemu_hw_version() to "2.5+"
There are two issues with qemu_hw_version() today:
1) If a machine has hw_version set, the value returned by it is
not very useful, because it is not the actual QEMU version.
2) If a machine does't set hw_version, the return value of
qemu_hw_version() is broken, because it will change when
upgrading QEMU.
For those reasons, using qemu_hw_version() is strongly
discouraged, and should be used only in code that used
QEMU_VERSION in the past and needs to keep compatibility.
To fix (2), instead of making every machine broken by default
unless they set hw_version, make qemu_hw_version() simply return
"2.5+" if qemu_set_hw_version() is not called.

ivshmem: Rename property memdev to x-memdev for 2.5
The device's guest interface and its QEMU user interface are
flawed^Whotly debated. We'll resolve that in the next development
cycle, probably by deprecating the device in favour of a cleaned up,
but not quite compatible revision.
To avoid adding more baggage to the soon-to-be-deprecated interface,
mark property "memdev" as experimental, by renaming it to "x-memdev".
It's the only recent user interface change.

target-mips: flush QEMU TLB when disabling 64-bit addressing
CP0.Status.KX/SX/UX bits are responsible for enabling access to 64-bit
Kernel/Supervisor/User Segments. If bit is cleared an access to
corresponding segment should generate Address Error Exception.
However, the guest may still be able to access some pages belonging to
the disabled 64-bit segment because we forget to flush QEMU TLB.
This patch fixes it.

target-mips: Fix exceptions while UX=0
Commit 01f728857941 ("target-mips: Status.UX/SX/KX enable 32-bit address
wrapping") added a new hflag MIPS_HFLAG_AWRAP, which indicates that
64-bit addressing is disallowed in the current mode, so hflag users
don't need to worry about the complexities of working that out, for
example checking both MIPS_HFLAG_KSU and MIPS_HFLAG_UX.
However when exceptions are taken outside of exception level,
mips_cpu_do_interrupt() manipulates the env->hflags directly rather than
using compute_hflags() to update them, and this code wasn't updated
accordingly. As a result, when UX is cleared, MIPS_HFLAG_AWRAP is set,
but it doesn't get cleared on entry back into kernel mode due to an
exception. Kernel mode then cannot access the 64-bit segments resulting
in a nested exception loop. The same applies to errors and debug
exceptions.
Fix by updating mips_cpu_do_interrupt() to clear the MIPS_HFLAG_WRAP
flag when necessary, according to compute_hflags().

parallels: dirty BAT properly for continuous allocations
This patch marks part of the BAT dirty properly. There is a possibility that
multy-block allocation could have one block allocated on one BAT page and
next block on the next page. The code without the patch could not save
updated position to the file.

hostmem: Ignore ENOSYS while setting MPOL_DEFAULT
Currently hostmem backend fails if CONFIG_NUMA is enabled in QEMU
(the default) but NUMA is not supported by the kernel. This makes
it impossible to use ivshmem in such configurations.
This patch fixes the problem by ignoring ENOSYS error if policy is set to
MPOL_DEFAULT. This way the code behaves in the same way as if CONFIG_NUMA
was not defined. qemu will still fail if the user specifies some other
policy, so that the user knows it.

qom: Replace object property list with GHashTable
ARM GICv3 systems with large number of CPUs create lots of IRQ pins. Since
every pin is represented as a property, number of these properties becomes
very large. Every property add first makes sure there's no duplicates.
Traversing the list becomes very slow, therefore QEMU initialization takes
significant time (several seconds for e. g. 16 CPUs).
This patch replaces list with GHashTable, making lookup very fast. The only
drawback is that object_child_foreach() and object_child_foreach_recursive()
cannot add or remove properties during traversal, since GHashTableIter does
not have modify-safe version. However, the code seems not to modify objects
via these functions.

vhost-user-test prints a warning. A test should not need to run on

condition can't check on qtest_enabled() since vhost-user-test actually
doesn't use qtest accel. However, qtest_driver() can be used, if
qtest_init() is called early enough. For that reason, move chardev and

tests: re-enable vhost-user-test
Commit 7fe34ca9c2e actually disabled vhost-user-test altogether,
since CONFIG_VHOST_NET is a per-target config variable.
tests/vhost-user-test is already x86/x64 softmmu specific test, in order
to enable it correctly, kvm & vhost-net are also conditions. To check
that, set CONFIG_VHOST_NET_TEST_$target when kvm is also enabled.
Since "check-qtest-x86_64-y = $(check-qtest-i386-y)", avoid duplication
when both x86 & x64 are enabled.
Other targets than x86 aren't enabled yet, and is intentionally left as
a future improvement, since I can't easily test those.

acpi: fix buffer overrun on migration
ich calls acpi_gpe_init with length ICH9_PMIO_GPE0_LEN so
ICH9_PMIO_GPE0_LEN/2 bytes are allocated, but then the full
ICH9_PMIO_GPE0_LEN bytes are migrated.
As a quick work-around, allocate twice the memory.
We'll probably want to tweak code to avoid
migrating the extra ICH9_PMIO_GPE0_LEN/2 bytes,
but that is a bit trickier to do without breaking
migration compatibility.

qom: Add a test case for complex property finalization
Devices have some quite complex object child/link relationships
which place some requirements on the object_property_del_all()
function to consider that properties can be modified while
being iterated over.
This extends the QOM property test case to replicate the
device like structure and expose any potential bugs in the
object_property_del_all() function.

qom: Introduce ObjectPropertyIterator struct for iteration
Some users of QOM need to be able to iterate over properties
defined against an object instance. Currently they are just
directly using the QTAIL macros against the object properties
data structure.
This is bad because it exposes them to changes in the data
structure used to store properties, as well as changes in
functionality such as ability to register properties against
the class.
This provides an ObjectPropertyIterator struct which will
insulate the callers from the particular data structure
used to store properties. It can be used thus
ObjectProperty *prop;
ObjectPropertyIterator *iter;
iter = object_property_iter_init(obj);
while ((prop = object_property_iter_next(iter))) {
... do something with prop ...
}
object_property_iter_free(iter);

qdev: Change Property::offset field to ptrdiff_t type
Property::offset field is calculated as a diff between two pointers:
arrayprop->prop.offset = eltptr - (void *)dev;
If offset is declared as int, this subtraction can cause type overflow,
thus leading to failure of the subsequent assertion:
assert(qdev_get_prop_ptr(dev, &arrayprop->prop) == eltptr);
So ptrdiff_t should be used instead.

crypto: avoid passing NULL to access() syscall
The qcrypto_tls_creds_x509_sanity_check() checks whether
certs exist by calling access(). It is valid for this
method to be invoked with certfile==NULL though, since
for client credentials the cert is optional. This caused
it to call access(NULL), which happens to be harmless on
current Linux, but should none the less be avoided.

makefile: fix w32 install target for qemu-ga
fafcaf1 added a 'qemu-ga' install target on w32, which can be used
in place of the existing qemu-ga.exe target to also handle dealing
with other components such as DLLs for VSS/fsfreeze and generating
an MSI package if appropriate configure options are present.
As part of that, qemu-ga$(EXESUF) was removed from $TOOLS in favor
of this new qemu-ga target.
The install rule however relies on a direct mapping of the $TOOLS
entry to the actual resulting binary. In the case of w32, qemu-ga
is not identical to qemu-ga$(EXESUF), and the install recipe fails
to find the 'qemu-ga' binary.
Fix this by essentially remapping 'qemu-ga' back to 'qemu-ga.exe'
in the install recipe.
This raises the question of whether or not qemu-ga should continue
to live in TOOLS as opposed to its own special target, but as a
late fix for a regression in 2.5 this commit should be safer, since
we rely on qemu-ga's presence in $TOOLS in several places throughout
Makefile.

ide: orphan all buffered requests on DMA cancel
If the guests canceles a DMA request we can prematurely
invoke all callbacks of buffered requests and flag all them
as orphaned. Ideally this avoids the need for draining all
requests. For CDROM devices this works in 100% of all cases.

ide: add support for IDEBufferedRequest
this patch adds a new aio readv compatible function which copies
all data through a bounce buffer. These buffered requests can be
flagged as orphaned which means that their original callback has
already been invoked and the request has just not been completed
by the backend storage. The bounce buffer guarantees that guest
memory corruption is avoided when such a orphaned request is
completed by the backend at a later stage.
This trick only works for read requests as a write request completed
at a later stage might corrupt data as there is no way to control
if and what data has already been written to the storage.

ide/atapi: make PIO read requests async
PIO read requests on the ATAPI interface used to be sync blk requests.
This has two significant drawbacks. First the main loop hangs util an
I/O request is completed and secondly if the I/O request does not
complete (e.g. due to an unresponsive storage) Qemu hangs completely.
Note: Due to possible race conditions requests during an ongoing
elementary transfer are still sync.

KVM can't virtualize rdtscp on AMD CPUs yet, so there's no point
in enabling it by default on AMD CPU models, as all we are

Disable rdtscp on Opteron_G* models, but keep compatibility on

virtio-blk: Fix double completion for werror=stop
When a request R is absorbed by request M, it is appended to the
"mr_next" queue led by M, and is completed together with the completion
of M, in virtio_blk_rw_complete.
During DMA restart in virtio_blk_dma_restart_bh, requests in s->rq are
parsed and submitted again, possibly with a stale req->mr_next. It could
be a problem if the request merging in virtio_blk_handle_request hasn't
refreshed every mr_next pointer, in which case, virtio_blk_rw_complete
could walk through unexpected requests following the stale pointers.
Fix this by unsetting the pointer in virtio_blk_rw_complete. It is safe
because this req is either completed and freed right away, or it will be
restarted and parsed from scratch out of the vq later.

input: Document why x-input-send-event is still experimental
The x-input-send-event command was introduced in 2.2 with mention
that it is experimental, but now that several releases have elapsed
without any changes, it would be nice to document why that was done
and should still remain experimental in 2.5.
Meanwhile, our documentation states that we prefer 'lower-case',
rather than 'CamelCase', for qapi enum values. The InputButton and
InputAxis enums violate this convention. However, because they are
currently used primarily for generating code that is used internally;
and their only exposure through QMP is via the experimental
'x-input-send-event' command, we are free to change their spelling.
Of course, it would be nicer to delay such a change until the same
time we promote the command to non-experimental. Adding
documentation will help us remember to do that rename.
We have plans to tighten the qapi generator to flag instances of
inconsistent use of naming conventions; if that lands first, it
will just need to whitelist these exceptions until the time we
settle on the final interface.
Fix a typo in the docs for InputAxis while at it.

seccomp: loosen library version dependency
Drop the libseccomp required version back to 2.1.0, restoring the ability
to build w/ --enable-seccomp on Ubuntu 14.04.
Commit 4cc47f8b3cc4f32586ba2f7fce1dc267da774a69 tightened the dependency
on libseccomp from version 2.1.0 to 2.1.1. This broke building on Ubuntu
14.04, the current Ubuntu LTS release. The commit message didn't mention
any specific functional need for 2.1.1, just that it was the most recent
stable version at the time. I reviewed the changes between 2.1.0 and 2.1.1,
but it looks like that update just contained minor fixes and cleanups - no
obvious (to me) new interfaces or critical bug fixes.

configure: arm/aarch64: allow enable-seccomp
This is a revert of ae6e8ef11e6cb, but with a bit of refactoring,
and also specifically adding arm/aarch64, rather than all
architectures. Currently, libseccomp code appears to also support
mips, ppc, and s390. We could therefore allow qemu to enable
seccomp for those platforms as well, with additional configure
patches, given they're tested and proven to work.

seccomp: add cacheflush to whitelist
cacheflush is an arm-specific syscall that qemu built for arm

xen: fix usage of xc_domain_create in domain builder
Due to the addition of HVMlite and the requirement to always provide a
valid xc_domain_configuration_t, xc_domain_create now always takes an arch
domain config, which can be NULL in order to mimic previous behaviour.
Add a small stub called xen_domain_create that encapsulates the correct
call to xc_domain_create depending on the libxc version detected.

migration_init: Fix lock initialisation/make it explicit
Peter reported a lock error on MacOS after my a82d593b
patch.
migrate_get_current does one-time initialisation of
a bunch of variables.
migrate_init does reinitialisation even on a 2nd
migrate after a cancel.
The problem here was that I'd initialised the mutex
in migrate_get_current, and the memset in migrate_init
corrupted it.
Remove the memset and replace it by explicit initialisation
of fields that need initialising; this also turns out to be simpler
than the old code that had to preserve some fields.

block: Add average I/O queue depth to BlockDeviceTimedStats
This patch adds two new fields to BlockDeviceTimedStats that track the
average number of pending read and write requests for a block device.
The values are calculated for the period of time defined for that

util: Infrastructure for computing recent averages
This module computes the average of a set of values within a time
window, keeping also track of the minimum and maximum values.
In order to produce more accurate results it works internally by
creating two time windows of the same period, offsetted by half of
that period. Values are accounted on both windows and the data is
always returned from the oldest one.

block: rename BlkTransactionState and BdrvActionOps
These structures are misnomers, somewhat.
(1) BlockTransactionState is not state for a transaction,
but is rather state for a single transaction action.
Rename it "BlkActionState" to be more accurate.
(2) The BdrvActionOps describes operations for the BlkActionState,
above. This name might imply a 'BdrvAction' or a 'BdrvActionState',
which there isn't.
Rename this to 'BlkActionOps' to match 'BlkActionState'.
Lastly, update the surrounding in-line documentation and comments
to reflect the current nature of how Transactions operate.
This patch changes only comments and names, and should not affect
behavior in any way.

block: Introduce BlockDriver.bdrv_drain callback
Drivers can have internal request sources that generate IO, like the
need_check_timer in QED. Since we want quiesced periods that contain
nested event loops in block layer, we need to have a way to disable such
event sources.
Block drivers must implement the "bdrv_drain" callback if it has any
internal sources that can generate I/O activity, like a timer or a
worker thread (even in a library) that can schedule QEMUBH in an
asynchronous callback.
Update the comments of bdrv_drain and bdrv_drained_begin accordingly.
Like bdrv_requests_pending(), we should consider all the children of bs.
Before, the while loop just works, as bdrv_requests_pending() already
tracks its children; now we mustn't miss the callback, so recurse down
explicitly.

easier if we unify the two paths, because we'll need to run it in a

virtio-9p: add savem handlers
We don't support migration of mounted 9p shares. This is handled by a
migration blocker.
One would expect, however, to be able to migrate if the share is unmounted.
Unfortunately virtio-9p-device does not register savevm handlers at all !
Migration succeeds and leaves the guest with a dangling device...
This patch simply registers migration handlers for virtio-9p-device. Whether
migration is possible or not still depends on the migration blocker.

virtio-pci: introduce pio notification capability for modern device
We used to use mmio for notification. This could be slow on some arch
(e.g on x86 without EPT). So this patch introduces pio bar and a pio
notification cap for modern device. This ability is enabled through
property "modern-pio-notify" for virtio pci devices and was disabled
by default. Management can enable when it thinks it was needed.
Benchmarks shows almost no obvious difference compared to legacy
device on machines without ept. Thanks Wenli Quan <wquan@redhat.com>

virtio-pci: use zero length mmio eventfd for 1.0 notification cap when possible
We use data match eventfd for 1.0 notification currently. This could
be slow since software decoding is needed for mmio exit. To speed this
up, we can switch to use zero length mmio eventfd for 1.0 notification
since we can examine the queue index directly from the writing
address. KVM kernel module can utilize this by registering it to fast
mmio bus which could be as fast as pio on ept capable machine when
fast mmio is supported by host kernel.
Lots of improvements were seen on a ept capable machine:

virtio-pci: fix 1.0 virtqueue migration
We don't migrate the followings fields for virtio-pci:
uint32_t dfselect;
uint32_t gfselect;
uint32_t guest_features[2];
struct {
uint16_t num;
bool enabled;
uint32_t desc[2];
uint32_t avail[2];
uint32_t used[2];
} vqs[VIRTIO_QUEUE_MAX];
This will confuse driver if migrating during initialization. Solves
this issue by:
- introduce transport specific callbacks to load and store extra
virtqueue states.
- add a new subsection for virtio to migrate transport specific modern
device state.
- implement pci specific callbacks.
- add a new property for virtio-pci for whether or not to migrate
extra state.
- compat the migration for 2.4 and elder machine types

e1000: Introducing backward compatibility command line parameter
This follows the previous patches, where support for migrating the
entire MAC registers' array, and some new MAC registers were introduced.
This patch introduces the e1000-specific boolean parameter
"extra_mac_registers", which is on by default. Setting it to off will
enable migration to older versions of QEMU, but will disable the read
and write access to the new registers, that were introduced since adding
the ability to migrate the entire MAC array.
Example for usage to enable backward compatibility and to disable the
new MAC registers:
qemu-system-x86_64 -device e1000,extra_mac_registers=off,... ...
As mentioned above, the default value is "on".

e1000: Fixing the received/transmitted octets' counters
Previously, these 64-bit registers did not stick at their maximal
values when (and if) they reached them, as they should do, according to
the specs.
This patch introduces a function that takes care of such registers,
avoiding code duplication, making the relevant parts more compatible
with the QEMU coding style, while ensuring that in the unlikely case
of reaching the maximal value, the counter will stick there, as it
supposed to.

e1000: Trivial implementation of various MAC registers
These registers appear in Intel's specs, but were not implemented.
These registers are now implemented trivially, i.e. they are initiated
with zero values, and if they are RW, they can be written or read by the
driver, or read only if they are R (essentially retaining their zero
values). For these registers no other procedures are performed.
For the trivially implemented Diagnostic registers, a debug warning is
produced on read/write attempts.
PLEASE NOTE: these registers will not be active, nor will migrate, until
a compatibility flag will be set (in a later patch in this series).
The registers implemented here are:
Transmit:
RW: AIT
Management:
RW: WUC WUS IPAV IP6AT* IP4AT* FFLT* WUPM* FFMT* FFVT*
Diagnostic:
RW: RDFH RDFT RDFHS RDFTS RDFPC PBM* TDFH TDFT TDFHS

Statistic:
RW: FCRUC
R: RNBC TSCTFC MGTPRC MGTPDC MGTPTC RFC RJC SCC ECOL

e1000: Introduced an array to control the access to the MAC registers
The array of uint8_t's which is introduced here, contains access metadata
about the MAC registers: if a register is accessible, but partly implemented,
or if a register requires a certain compatibility flag in order to be
accessed. Currently, 6 hypothetical flags are supported (3 exist for e1000
so far) but in the future, if more than 6 flags will be needed, the datatype
of this array can simply be swapped for a larger one.
This patch is intended to solve the following current problems:
1) In a scenario of migration between different versions of QEMU, which
differ by the MAC registers implemented in them, some registers need not to
be active if a compatibility flag is set, in order to preserve the machine's
state perfectly for the older version. Checking this for each register
individually, would create a lot of clutter in the code.
2) Some registers are (or may be) only partly implemented (e.g.
placeholders that allow reading and writing, but lack other functions).
In such cases it is better to print a debug warning on read/write attempts.
As above, dealing with this functionality on a per-register level, would
require longer and more messy code.

e1000: Add support for migrating the entire MAC registers' array
This patch makes the migration of the entire array of MAC registers
possible during live migration. The entire array is just 128 KB long, so
practically no penalty should be felt when transmitting it, additionally
to the previously transmitted individual registers. The advantage here is
eliminating the need to introduce new vmstate subsections in the future,
when additional MAC registers will be implemented.
Backward compatibility is preserved by introducing a e1000-specific
boolean parameter (in a later patch), which will be on by default.
Setting it to off would enable migration to older versions of QEMU.
Additionally, this parameter will be used to control the access to the
extra MAC registers in the future.

monitor/target-ppc: Define target_get_monitor_def
At the moment get_monitor_def() returns only registers from statically
defined monitor_defs array. However there is a lot of BOOK3S SPRs
which are not in the list and cannot be printed from the monitor.
This adds a new target platform hook - target_get_monitor_def().
The hook is called if a register was not found in the static
array returned by the target_monitor_defs() hook.
The hook is only defined for POWERPC, it returns registered
SPRs and fails on unregistered ones providing the user with information
on what is actually supported on the running CPU. The register value is
saved as uint64_t as it is the biggest supported register size;
target_ulong cannot be used because of the stub - it is in a "common"
code and cannot include "cpu.h", etc; this is also why the hook prototype
is redefined in the stub instead of being included from some header.
This replaces static descriptors for GPRs, FPRs, SRs with a helper which
looks for a value in a corresponding array in the CPUPPCState.
The immediate effect is that all 32 SRs can be printed now (instead of 16);
later this can be reused for VSX or TM registers.
This replaces callbacks for MSR and XER with static descriptors in
monitor_defs as they are stored in CPUPPCState.
While we are here, this adds "cr" as a synonym of "ccr".

PPC: Allow Rc bit to be set on mtspr
According to the ISA setting the Rc bit on mtspr is undefined behavior.
Real 750 hardware simply ignores the bit and doesn't touch cr0 though.
Unfortunately, Mac OS 9 relies on this fact and executes a few mtspr
instructions (to set XER for example) with Rc set.
So let's handle the bit the same way hardware does and ignore it.

s390: deprecate the non-ccw machine in 2.5
The non-ccw machine for s390 (s390-virtio) is not very well maintained
and caused several issues in the past:
- aliases like virtio-blk did not work for s390
- virtio refactoring failed due to long standing bugs (e.g.see
commit cb927b8a "s390-virtio: Accommodate guests using virtqueues too early")
- some features like memory hotplug will cause trouble due to virtio storage
being above guest memory
- the boot loader bios no longer seems to work. the source code of that
loader is also no longer maintained
2.4 changed the default to the ccw machine, let's deprecate the old
machine for 2.5.

pc-bios/s390-ccw: El Torito 16-bit boot image size field workaround
Because of El Torito spec flaw boot image size needs to be verified.
Boot catalog entry size field has 16-bit width, and specifies size
in 512-byte units.
Thus, boot image size cannot exceed 32M.
We actually search for the file to get the file size.
This is done by scanning the ISO directory tree for the ISO block number
and reading the file size from the directory entry.

s390x/pci : fix up s390 pci iommu translation function
On s390x, each pci device has its own iommu, which is only properly
setup in qemu once the mpcifc instruction used to register the
translation table has been intercepted. Therefore, for a pci device that
is not configured or has not been initialized, proper translation is
neither required nor possible. Moreover, we may not have a host bridge
device ready yet.
This was exposed by a recent vfio change that triggers iommu translation
during the initialization of the vfio pci device. Let's do an early exit
in that case.

We keep the device's sense data in a byte array (following the

just blindly copy the values, the sense data will change from
de-facto BE data to de-facto cpu-endian data, which means we end
up doing an incorrect conversion on LE hosts.

qemu-iotests: fix -valgrind option for check
Commit 934659c switched the iotests to run qemu-io from a bash subshell,
in order to catch segfaults. This method is incompatible with the
current valgrind_qemu_io() bash function.
Move the valgrind usage into the exec subshell in _qemu_io_wrapper(),
while making sure the original return value is passed back to the
caller.
Update test output for tests 039, 061, and 137 as it looks for the
specific subshell command when the process is terminated.

qemu-iotests: fix cleanup of background processes
Commit 934659c switched the iotests to run qemu and qemu-nbd from a bash
subshell, in order to catch segfaults. Unfortunately, this means the
process PID cannot be captured via '$!'. We stopped killing qemu and
qemu-nbd processes, leaving a lot of orphaned, running qemu processes
after executing iotests.
Since the process is using exec in the subshell, the PID is the
same as the subshell PID.
Track these PIDs for cleanup using pidfiles in the $TEST_DIR. Only
track the qemu PID, however, if requested - not all usage requires
killing the process.

throttle: Use bs->throttle_state instead of bs->io_limits_enabled
There are two ways to check for I/O limits in a BlockDriverState:
- bs->throttle_state: if this pointer is not NULL, it means that this
BDS is member of a throttling group, its ThrottleTimers structure
has been initialized and its I/O limits are ready to be applied.
- bs->io_limits_enabled: if true it means that the throttle_state
pointer is valid _and_ the limits are currently enabled.
The latter is used in several places to check whether a BDS has I/O
limits configured, but what it really checks is whether requests
are being throttled or not. For example, io_limits_enabled can be
temporarily set to false in cases like bdrv_read_unthrottled() without
otherwise touching the throtting configuration of that BDS.
This patch replaces bs->io_limits_enabled with bs->throttle_state in
all cases where what we really want to check is the existence of I/O
limits, not whether they are currently enabled or not.

throttle: Check for pending requests in throttle_group_unregister_bs()
throttle_group_unregister_bs() removes a BlockDriverState from its
throttling group and destroys the timers. This means that there must
be no pending throttled requests at that point (because it would be
impossible to complete them), so the caller has to drain them first.
At the moment throttle_group_unregister_bs() is only called from
bdrv_io_limits_disable(), which already takes care of draining the
requests, so there's nothing to worry about, but this patch makes
this invariant explicit in the documentation and adds the relevant
assertions.

qemu-iotests: Test the reopening of overlay_bs in 'block-commit'
The 'block-commit' command needs the overlay image of 'top' to
be opened in read-write mode in order to update the backing file
string. If 'top' is not the active layer or its backing file then its
overlay needs to be reopened during the block job.
This is a test case for that scenario.

commit: reopen overlay_bs before base
'block-commit' needs write access to two different nodes of the chain:
- 'base', because that's where the data is written to.
- the overlay of 'top', because it needs to update the backing file
string to point to 'base' after the operation.
Both images have to be opened in read-write mode, and commit_start()
takes care of reopening them if necessary.
With the current implementation, however, when overlay_bs is reopened
in read-write mode it has the side effect of making 'base' read-only
again, eventually making 'block-commit' fail.
This needs to be fixed in bdrv_reopen(), but until we get to that it
can be worked around simply by swapping the order of base and
overlay_bs in the reopen queue.
In order to reproduce this bug, overlay_bs needs to be initially in
read-only mode. That is: the 'top' parameter of 'block-commit' cannot
be the active layer nor its immediate backing chain.

block: add a 'blockdev-snapshot' QMP command
One of the limitations of the 'blockdev-snapshot-sync' command is that
it does not allow passing BlockdevOptions to the newly created
snapshots, so they are always opened using the default values.
Extending the command to allow passing options is not a practical
solution because there is overlap between those options and some of
the existing parameters of the command.
This patch introduces a new 'blockdev-snapshot' command with a simpler
interface: it just takes two references to existing block devices that
will be used as the source and target for the snapshot.
Since the main difference between the two commands is that one of them
creates and opens the target image, while the other uses an already
opened one, the bulk of the implementation is shared.

block: support passing 'backing': '' to 'blockdev-add'
Passing an empty string allows opening an image but not its backing
file. This was already described in the API documentation, only the
implementation was missing.
This is useful for creating snapshots using images opened with
blockdev-add, since they are not supposed to have a backing image
before the operation.

block: check for existing device IDs in external_snapshot_prepare()
The 'snapshot-node-name' parameter of blockdev-snapshot-sync allows
setting the node name of the image that is going to be created.
Before creating the image, external_snapshot_prepare() checks that the
name is not already being used. The check is however incomplete since
it only considers existing node names, but node names must not clash
with device IDs either because they share the same namespace.
If the user attempts to create a snapshot using the name of an
existing device for the 'snapshot-node-name' parameter the operation
will eventually fail, but only after the new image has been created.
This patch replaces bdrv_find_node() with bdrv_lookup_bs() to extend
the check to existing device IDs, and thus detect possible name
clashes before the new image is created.

block: Inquire tray state before tray-moved events
blk_dev_change_media_cb() is called for all potential tray movements;
however, it is possible to request closing the tray but nothing actually
happening (on a floppy disk drive without a medium).
Thus, the actual tray status should be inquired before sending a
tray-moved event (and an event should be sent whenever the status
changed).
Checking @load is now superfluous; it was necessary because it was
possible to change a medium without having explicitly opened the tray
and closed it again (or it might have been possible, at least). This is
no longer possible, though.

spapr: Handle failure of KVM_PPC_ALLOCATE_HTAB ioctl
KVM_PPC_ALLOCATE_HTAB ioctl can return -ENOMEM for KVM guests and QEMU
never handled this correctly. But this didn't cause any problems till
now as KVM_PPC_ALLOCATE_HTAB ioctl returned with smaller than requested
HTAB when enough contiguous memory wasn't available in the host.
After the proposed kernel change: https://patchwork.ozlabs.org/patch/530501/,
KVM_PPC_ALLOCATE_HTAB ioctl will not fallback to lower sized HTAB
allocation and will fail if requested HTAB size can't be met.
Check for such failures in QEMU and abort appropriately. This will
prevent guest kernel from hanging/freezing during early boot by doing
graceful exit when host is unable to allocate requested HTAB.

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T). Same Coccinelle semantic patch as in commit b45c03f.

vfio/pci: Hide device PCIe capability on non-express buses for PCIe VMs
When we have a PCIe VM, such as Q35, guests start to care more about
valid configurations of devices relative to the VM view of the PCI
topology. Windows will error with a Code 10 for an assigned device if
a PCIe capability is found for a device on a conventional bus. We
also have the possibility of IOMMUs, like VT-d, where the where the
guest may be acutely aware of valid express capabilities on physical
hardware.
Some devices, like tg3 are adversely affected by this due to driver
dependencies on the PCIe capability. The only solution for such
devices is to attach them to an express capable bus in the VM.

Inhibit ballooning during postcopy
Postcopy detects accesses to pages that haven't been transferred yet
using userfaultfd, and it causes exceptions on pages that are 'not
present'.
Ballooning also causes pages to be marked as 'not present' when the
guest inflates the balloon.
Potentially a balloon could be inflated to discard pages that are
currently inflight during postcopy and that may be arriving at about
the same time.
To avoid this confusion, disable ballooning during postcopy.
When disabled we drop balloon requests from the guest. Since ballooning
is generally initiated by the host, the management system should avoid
initiating any balloon instructions to the guest during migration,
although it's not possible to know how long it would take a guest to
process a request made prior to the start of migration.
Guest initiated ballooning will not know if it's really freed a page
of host memory or not.
Queueing the requests until after migration would be nice, but is
non-trivial, since the set of inflate/deflate requests have to
be compared with the state of the page to know what the final
outcome is allowed to be.

Postcopy: Mark nohugepage before discard
Prior to servicing userfault requests we must ensure we've not got
huge pages in the area that might include non-transferred memory,
since a hugepage could incorrectly mark the whole huge page as present.
We mark the area as non-huge page (nhp) just before we perform
discards; the discard code now tells us to discard any areas
that haven't been sent (as well as any that are redirtied);
any already formed transparent-huge-pages get fragmented
by this discard process if they cotnain any discards.
Transparent huge pages that have been entirely transferred
and don't contain any discards are not broken by this mechanism;
they stay as huge pages.
By starting postcopy after a full precopy pass, many of the pages
then stay as huge pages; this is important for maintaining performance
after the end of the migration.

Round up RAMBlock sizes to host page sizes
RAMBlocks that are not a multiple of host pages in length
cause problems for postcopy (I've seen an ACPI table on aarch64
be 5k in length - i.e. 5x target-page), so round RAMBlock sizes
up to a host-page.
This potentially breaks migration compatibility due to changes
in RAMBlock sizes; however:
1) x86 and s390 I think always have host=target page size
2) When I've tried on Power the block sizes already seem aligned.
3) I don't think there's anything else that maintains per-version
machine-types for compatibility.

Once we're in postcopy the source processors are stopped and memory
shouldn't change any more, so there's no need to look at the dirty
map.
There are two notes to this:
1) If we do resync and a page had changed then the page would get
sent again, which the destination wouldn't allow (since it might
have also modified the page)
2) Before disabling this I'd seen very rare cases where a page had been
marked dirtied although the memory contents are apparently identical

Page request: Consume pages off the post-copy queue
When transmitting RAM pages, consume pages that have been queued by
MIG_RPCOMM_REQPAGE commands and send them ahead of normal page scanning.
Note:
a) After a queued page the linear walk carries on from after the
unqueued page; there is a reasonable chance that the destination
was about to ask for other closeby pages anyway.
b) We have to be careful of any assumptions that the page walking
code makes, in particular it does some short cuts on its first linear
walk that break as soon as we do a queued page.
c) We have to be careful to not break up host-page size chunks, since
this makes it harder to place the pages on the destination.

MIG_CMD_PACKAGED: Send a packaged chunk of migration stream
MIG_CMD_PACKAGED is a migration command that wraps a chunk of migration
stream inside a package whose length can be determined purely by reading
its header. The destination guarantees that the whole MIG_CMD_PACKAGED
is read off the stream prior to parsing the contents.
This is used by postcopy to load device state (from the package)
while leaving the main stream free to receive memory pages.

Postcopy needs to have two migration streams loading concurrently;

target-arm: Clean up DISAS_UPDATE usage in AArch32 translation code
AArch32 translation code does not distinguish between DISAS_UPDATE and
DISAS_JUMP. Thus, we cannot use any of them without first updating PC in
CPU state. Furthermore, it is too complicated to update PC in CPU state
before PC gets updated in disas context. So it is hardly possible to
correctly end TB early if is is not likely to be executed before calling
disas_*_insn(), e.g. just after calling breakpoint check helper.
Modify DISAS_UPDATE and DISAS_JUMP usage in AArch32 translation and
apply to them the same semantic as AArch64 translation does:
- DISAS_UPDATE: update PC in CPU state when finishing translation
- DISAS_JUMP: preserve current PC value in CPU state when finishing
translation
This patch fixes a bug in AArch32 breakpoint handling: when
check_breakpoints helper does not generate an exception, ending the TB
early with DISAS_UPDATE couldn't update PC in CPU state and execution
hangs.

In addition to PSCI, this board also uses SMC for cache maintenance
ops. This means we need a secure monitor to catch these and nop them.
Use the ARM boot board-setup feature to implement this. The SMC trap
implements the needed nop while all other traps will pen the CPU.
As a KVM CPU cannot run in secure mode, do not do the board-setup if
not running TCG. Report a warning explaining the limitation in this
case.

hw/intc/arm_gic: Remove the definition of NUM_CPU
arm_gic.c retrieves CPU number using either NUM_CPU(s) or s->num_cpu.
Such mixed-uses make source code inconsistent. This patch removes
NUM_CPU(s), which was defined for MPCore tweak long ago, and instead
favors s->num_cpu. The source is more consistent after this small tweak.

qapi-introspect: Document lack of sorting
qapi-code-gen.txt already claims that types, commands, and
events share a common namespace; set this in stone by further
documenting that our introspection output will never have
collisions with the same name tied to more than one meta-type.
Our largest QMP enum currently has 125 values, our largest
object type has 27 members, and the mean for each is less than
10. These sizes are small enough that the per-element overhead
of O(log n) binary searching probably outweighs the speed
possible with direct O(n) linear searching (a better algorithm
with more overhead will only beat a leaner naive algorithm only
as you scale to larger input sizes).
Arguably, the overall SchemaInfo array could be sorted by name;
there, we currently have 531 entities, large enough for a binary
search to be faster than linear. However, remember that we have
mutually-recursive types, which means there is no topological
ordering that will allow clients to learn all information about
that type in a single linear pass; thus clients will want to do
random access over the data, and they will probably read the
introspection output into a hashtable for O(1) lookup rather
than O(log n) binary searching, at which point, pre-sorting our
introspection output doesn't help the client.
It doesn't help that sorting can be subjective if you introduce
locales into the mix (I'm not experienced enough with Python
to know for sure, but at least it looks like it defaults to
sorting in the C locale even when run under a different locale).
And while our current introspection output is deterministic
(because we visit entities in a sorted order), we may want
to change that order in the future (such as using OrderedDict
to stick to .json declaration order).
For these reasons, we simply document that clients should not
rely on any particular order of items in introspection output.
And since it is now a documented part of the contract, we have
the freedom to later rearrange output if needed, without
worrying about breaking well-written clients.

qapi: Provide nicer array names in introspection
For the sake of humans reading introspection output, it is nice
to have the name of implicit array types be recognizable as
arrays of the underlying type. However, while this patch allows
humans to skip from a command with return type "[123]" straight
to the definition of type "123" without having to first inspect
type "[123]", document that this shortcut should not be taken by
client apps.
This makes the resulting introspection string slightly larger by
default (just over 200 bytes), but it's in the noise (less than
0.3% of the overall 70k size of 'query-qmp-capabilities').

qapi: More tests of input arrays
Our testsuite had no coverage of empty arrays, nor of what
happens when the input does not match the expected type.
Useful to have, especially if we start changing the visitor
contracts.
I did not think it worth duplicating these additions to
test-qmp-input-strict; since all strict mode does is add
the ability to reject JSON input that has more keys than
what the visitor expects, yet the additions in this patch
error out earlier than that point regardless of whether
strict mode was requested.

qapi: Test failure in middle of array parse
Our generated list visitors have the same problem as has been
mentioned elsewhere (see commit 2f52e20): they allocate data
even on failure. An upcoming patch will correct things to
provide saner guarantees, but first we need to expose the
behavior in the testsuite to ensure we aren't introducing any
memory usage bugs.
There are more test cases throughout the test-qmp-input-* tests
that already deal with partial allocation; a later commit will
clean up all visit_type_FOO(), without marking all of the tests
with FIXME at this time.

qapi: Simplify error cleanup in test-qmp-*
We have several tests that perform multiple sub-actions that are
expected to fail. Asserting that an error occurred, then clearing
it up to prepare for the next action, turned into enough
boilerplate that it was sometimes forgotten (for example, a number
of tests added to test-qmp-input-visitor.c in d88f5fd leaked err).
Worse, if an error is not reset to NULL, we risk invalidating
later use of that error (passing a non-NULL err into a function
is generally a bad idea). Encapsulate the boilerplate into a
single helper function error_free_or_abort(), and consistently
use it.
The new function is added into error.c for use everywhere,
although it is anticipated that testsuites will be the main
client.

hw/timer/hpet.c: Avoid signed integer overflow which results in bugs on OSX
Signed integer overflow in C is undefined behaviour, and the compiler
is at liberty to assume it can never happen and optimize accordingly.
In particular, the subtractions in hpet_time_after() and hpet_time_after64()
were causing OSX clang to optimize the code such that it was prone to
hangs and complaints about the main loop stalling (presumably because
we were spending all our time trying to service very high frequency
HPET timer callbacks). The clang sanitizer confirms the UB:
hw/timer/hpet.c:119:26: runtime error: signed integer overflow: -2146967296 - 2147003978 cannot be represented in type 'int'
Fix this by doing the subtraction as an unsigned operation and then
converting to signed for the comparison.

qapi: Simplify non-error testing in test-qmp-*
By using &error_abort, we can avoid a local err variable in
situations where we expect success. It also has the nice
effect that if the test breaks, the error message from
error_abort tends to be nicer than that of g_assert().
This patch has an additional bonus of fixing several call sites that
were passing &err to two different functions without checking it in
between. In general that is unsafe practice; because if the first
function sets an error, the second function could abort() if it tries to
set a different error. We got away with it because we were asserting
that err was NULL through the entire chain, but switching to
&error_abort avoids the questionable practice up front.

qapi: Plug leaks in test-qmp-*
Make valgrind happy with the current state of the tests, so that
it is easier to see if future patches introduce new memory problems
without being drowned in noise. Many of the leaks were due to
calling a second init without tearing down the data from an earlier
visit. But since teardown is already idempotent, and we already
register teardown as part of input_visitor_test_add(), it is nicer
to just make init() safe to call multiple times than it is to have
to make all tests call teardown.
Another common leak was forgetting to clean up an error object,
after testing that an error was raised.
Another leak was in test_visitor_in_struct_nested(), failing to
clean the base member of UserDefTwo. Cleaning that up left
check_and_free_str() as dead code (since using the qapi_free_*
takes care of recursion, and we don't want double frees).
A final leak was in test_visitor_out_any(), which was reassigning
the qobj local variable to a subset of the overall structure
needing freeing; it did not result in a use-after-free, but
was not cleaning up all the qdict.
test-qmp-event and test-qmp-commands were already clean.

qapi: Share test_init code in test-qmp-input*
Rather than duplicate the body of two functions just to
decide between qobject_from_jsonv() and qobject_from_json(),
exploit the fact that qobject_from_jsonv() intentionally
takes 'va_list *' instead of the more common 'va_list', and
that qobject_from_json() just calls qobject_from_jsonv(,NULL).
For each file, our two existing init functions then become
thin wrappers around a new internal function, and future
updates to initialization don't have to be duplicated.

qapi: Use generated TestStruct machinery in tests
Commit d88f5fd and friends first introduced the various test-qmp-*
tests in 2011, with duplicated hand-rolled TestStruct machinery,
to make sure the qapi visitor interface was tested. Later, commit
4f193e3 in 2013 added a .json file for further testing use by the
files, but without consolidating any of the existing hand-rolled
visitors. And with four copies, subtle differences have crept in,
between the tests themselves (mainly whitespace differences, but
also a question of whether to use NULL or "TestStruct" when
calling visit_start_struct()) and from what the generator produces
(the hand-rolled versions did not cater to partially-allocated
objects, because they did not have a deallocation usage).
Of course, just because the visitor interface is tested does not
mean it is a sane interface; and future patches will be changing
some of the visitor contracts. Rather than having to duplicate
the cleanup work in each copy of the TestStruct visitor, and keep
each hand-rolled copy in sync with what the generator supplies, we
might as well just test what the generator should give us in the
first place.

aio: Introduce aio-epoll.c
To minimize code duplication, epoll is hooked into aio-posix's
aio_poll() instead of rolling its own. This approach also has both
compile-time and run-time switchability.
1) When QEMU starts with a small number of fds in the event loop, ppoll
is used.
2) When QEMU starts with a big number of fds, or when more devices are
hot plugged, epoll kicks in when the number of fds hits the threshold.
3) Some fds may not support epoll, such as tty based stdio. In this
case, it falls back to ppoll.
A rough benchmark with scsi-disk on virtio-scsi dataplane (epoll gets
enabled from 64 onward). Numbers are in MB/s.
===============================================
| master | epoll
| |
scsi disks # | read randrw | read randrw
-------------|----------------|----------------
1 | 86 36 | 92 45
8 | 87 43 | 86 41
64 | 71 32 | 70 38
128 | 48 24 | 58 31
256 | 37 19 | 57 28
===============================================
To comply with aio_{disable,enable}_external, we always use ppoll when
aio_external_disabled() is true.

since the field is also referenced outside CONFIG_EPOLL code.

dataplane: support non-contigious s/g
bring_map currently fails if one of the entries it's mapping is
contigious in GPA but not HVA address space. Introduce a mapped_len
parameter so it can handle this, returning the actual mapped length.
This will still fail if there's no space left in the sg, but luckily max
queue size in use is currently 256, while max sg size is 1024, so we
should be OK even is all entries happen to cross a single DIMM boundary.
Won't work well with very small DIMM sizes, unfortunately:
e.g. this will fail with 4K DIMMs where a single
request might span a large number of DIMMs.
Let's hope these are uncommon - at least we are not breaking things.

ide: remove hardcoded 2GiB transactional limit
Not that you can request a >2GiB transaction, but that's why checking
for it makes no sense anymore.
With the newer 'limit' parameter to prepare_buf, we no longer need a
static limit. The maximum limit is still 2GiB, but the limit parameter
is set to the current transaction size, which cannot surpass 32MiB
(512 * 65536). If the PRDT surpasses the transactional size, then,
we'll just carry out the normative underflow handling pathways instead
of needing an extra, strange pathway that worries about hitting some
logistical cap for the largest sglist we can support -- we'll never
even attempt to build one that big anymore.

qemu-sockets: do not test path with access() before unlinking
Using access() is a time-of-check/time-of-use race condition. It is
okay to use them to provide better error messages, but that is pretty
much it.
This is not one such case; on the other hand, access() *will* skip
unlink() for a non-existent path, so ignore ENOENT return values from
the unlink() system call.

replay: ptimer
This patch adds deterministic replay for hardware periodic countdown timers.
ptimer uses bottom halves layer to execute such an asynchronous callback.
We put this callback into the replay queue instead of bottom halves one.
When checkpoint is met by main loop thread, the replay queue is processed
and callback is executed. Binding callback moment to one of the checkpoints
makes it deterministic.

replay: recording and replaying clock ticks
Clock ticks are considered as the sources of non-deterministic data for
virtual machine. This patch implements saving the clock values when they
are acquired (virtual, host clock).
When replaying the execution corresponding values are read from log and
transfered to the module, which wants to read the values.
Such a design required the clock polling to be synchronized. Sometimes
it is not true - e.g. when timeouts for timer lists are checked. In this case
we use a cached value of the clock, passing it to the client code.

target-i386: Set "check=off" by default on pc-*-2.4 and older
The default CPU model (qemu64) have some issues today: it enables some
features (ABM and SSE4a) that are not present in many host CPUs. That
means many hosts (but not all of them) had those features silently
disabled in the default configuration in QEMU 2.4 and older.
With the new "check=on" default, this causes warnings to be printed in
the default configuration, because of the lack of SSE4A on all Intel
hosts, and the lack of ABM on Sandy Bridge and older hosts:
$ qemu-system-x86_64 -machine pc,accel=kvm
warning: host doesn't support requested feature: CPUID.80000001H:ECX.abm [bit 5]
warning: host doesn't support requested feature: CPUID.80000001H:ECX.sse4a [bit 6]
Those issues will be fixed in pc-*-2.5 and newer. But as we can't change
the guest ABI in pc-*-2.4, disable "check" mode by default in pc-*-2.4
and older so we don't print spurious warnings.

kvmclock: add a new function to update env->tsc.
The commit 317b0a6d8 fixed an issue which caused by the outdated
env->tsc value, but the fix lead to 'cpu_synchronize_all_states()'
called twice during live migration. The 'cpu_synchronize_all_states()'
takes about 130us for a VM which has 4 vcpus, it's a bit expensive.
Synchronize the whole CPU context just for updating env->tsc is too
wasting, this patch use a new function to update the env->tsc.
Comparing to 'cpu_synchronize_all_states()', it only takes about 20us.

configure: disable FORTIFY_SOURCE under clang
Some versions of clang may have difficulty compiling glibc headers when
-D_FORTIFY_SOURCE is used. For example, Clang++ 3.5.0-9.fc22 cannot
compile glibc's stdio headers when -D_FORTIFY_SOURCE=2 is used. This
manifests currently as build failures with clang and any arm target.
According to LLVM dev Richard Smith, clang does not target or support
FORTIFY_SOURCE + glibc, and it should not be relied on.
"It's still an unsupported combination, and while it might compile, some
of the checks are unlikely to work because they require a frontend
inliner to be useful"
See: http://lists.llvm.org/pipermail/cfe-dev/2015-November/045846.html
Conclusion: disable fortify-source if we appear to be using clang instead
of testing for compile success or failure, which may be incidental or not
indicative of proper support of the feature.

backends/hostmem-file: Allow to specify full pathname for backing file
This allows to explicitly specify file name to use with the backend. This
is important when using it together with ivshmem in order to make it backed
by hugetlbfs. By default filename is autogenerated using mkstemp(), and the
file is unlink()ed after creation, effectively making it anonymous. This is
not very useful with ivshmem because it ends up in a memory which cannot be
accessed by something else.
Distinction between directory and file name is done by stat() check. If an
existing directory is given, the code keeps old behavior. Otherwise it
creates or opens a file with the given pathname.

configure: disallow ccache during compile tests
If the user is using ccache during the configuration step,
it may interfere with some of the configuration tests,
particularly the "Is ccache interfering with macro analysis" step,
which is a bit of a poetic problem.
1) Disallow ccache from reading from the cache during configure,
but don't disable it entirely to allow us to see if it causes other
problems.
2) Force off CCACHE_CPP2 during the ccache test to get a deterministic
answer over whether or not we need to enable that feature later.

cpu-exec: Fix compiler warning (-Werror=clobbered)
Reloading of local variables after sigsetjmp is only needed for some
buggy compilers.
The code which should reload these variables causes compiler warnings
with gcc 4.7 when compiler optimizations are enabled:
cpu-exec.c:204:15: error:
variable ‘cpu’ might be clobbered by ‘longjmp’ or ‘vfork’ [-Werror=clobbered]
cpu-exec.c:207:15: error:
variable ‘cc’ might be clobbered by ‘longjmp’ or ‘vfork’ [-Werror=clobbered]
cpu-exec.c:202:28: error:
argument ‘env’ might be clobbered by ‘longjmp’ or ‘vfork’ [-Werror=clobbered]
Now this code is only used for compilers which need it
(and gcc 4.5.x, x > 0 which does not need it but won't give warnings).
There were bug reports for clang and gcc 4.5.0, while gcc 4.5.1
was reported to work fine without the reload code. For clang it
is not clear which versions are affected, so simply keep the status quo
for all clang compilations. This can be improved later.

memory: call begin, log_start and commit when registering a new listener
This ensures that cpu_reload_memory_map() is called as soon as
tcg_cpu_address_space_init() is called, and before cpu->memory_dispatch
is used. qemu-system-s390x never changes the address spaces after
tcg_cpu_address_space_init() is called, and thus tcg_commit() is never
called. This causes a SIGSEGV.
Because memory_map_init() will now call mem_commit(), we have to
initialize io_mem_* before address_space_memory and friends.

pc: Set hw_version on all machine classes
In 2012, QEMU had a bug where it exposed QEMU version information to the
guest, meaning a QEMU upgrade would expose different hardware to the
guest OS even if the same machine-type is being used.
The bug was fixed by commit 93bfef4c6e4b23caea9d51e1099d06433d8835a4, on
all machines up to pc-1.0. But we kept introducing the same bug on all
newer machines since then. That means we are breaking guest ABI every
time QEMU was upgraded.
Fix this by setting the hw_version on all PC machines, making sure the
hardware won't change when upgrading QEMU.
Note that QEMU_VERSION was "1.0" in QEMU 1.0, but starting on QEMU
1.1.0, it started following the "x.y.0" pattern. We have to follow it,
to make sure we use the right QEMU_VERSION string from each QEMU
release.
The 2.5 machine classes could have hw_version unset, because the default
value for qemu_get_version() is QEMU_VERSION. But I decided to set it
explicitly to QEMU_VERSION so we don't forget to update it to "2.5.0"
after we release 2.5.0 and create a 2.6 machine class.

target-i386: fix pcmpxstrx equal-ordered (strstr) mode
In this mode, referring an invalid element of the source forces the
result to false (table 4-7, last column) but referring an invalid
element of the destination forces the result to true, so the outer
loop should still be run even if some elements of the destination
will be invalid. They will be avoided in the inner loop, which
correctly bounds "i" to validd, but they will still contribute to a
positive outcome of the search.
This fixes tst_strstr in glibc 2.17.

qga: set file descriptor in qmp_guest_file_open non-blocking on Win32
Set fd non-blocking to avoid common use cases (like reading from a
named pipe) from hanging the agent. This was missed in the original
code.
The patch introduces qemu_set_handle_nonoblocking, the local analog
of qemu_set_nonblock for HANDLES.
The usage of handles in qemu_set_non/block is impossible, because for
win32 there is a difference between file discriptors and file handles,
and all file ops are made via Win32 api.

migration: defer migration_end & blk_mig_cleanup
Because of the patch 3ea3b7fa9af067982f34b of kvm, which introduces a
lazy collapsing of small sptes into large sptes mechanism, now
migration_end() is a time consuming operation because it calls
memroy_global_dirty_log_stop(), which will trigger the dropping of small
sptes operation and takes about dozens of milliseconds, so call
migration_end() before all the vmsate data has already been transferred
to the destination will prolong VM downtime. This operation should be
deferred after all the data has been transferred to the destination.
blk_mig_cleanup() can be deferred too.
For a VM with 8G RAM, this patch can reduce the VM downtime about 30 ms.

ehci: clear suspend bit on detach
When a device is detached, clear the suspend bit (PORTSC_SUSPEND)
in the port status register.
The specs are not *that* clear what is supposed to happen in case
a suspended device is unplugged. But the enable bit (PORTSC_PED)
is cleared, and the specs mention setting suspend with enable being
unset is undefined behavior. So clearing them both looks reasonable,
and it actually fixes the reported bug.

vnc: fix bug: vnc server can't start when 'to' is specified
commit e0d03b8ceb52 converted VNC startup to use SocketAddress,
the interface socket_listen don't have a port_offset param, so
we need to add the port offset (5900) to both 'port' and 'to' opts.
currently only 'port' is added by offset.
This patch add the port offset to 'to' opts.

vnc: allow fall back to RAW encoding
I have observed that depending on the contents and the encoding it happens
that sending data as RAW sometimes would take less space than the encoded data.
This is especially the case for small updates or areas with high color images.
If sending RAW encoded data is beneficial allow a fall back to RAW encoding
for the framebuffer update.

ui/opengl: Reduce build required libraries for opengl
We now use epoxy to load opengl libraries. This means we don't need to
link opengl libraries directly if interfaces handled by epoxy. With
this, we just need epoxy headers and epoxy's *.so to build.
Tested with epoxy-1.3.1.
- sdl2/gtk/console egl stuff doesn't require other than epoxy
- milkymist-tmu2 glx stuff doesn't require other than epoxy
(lm32 test is limited, because can't find mmone-bios.bin, so just test
to load libGL with "./lm32-softmmu/qemu-system-lm32 -M milkymist,accel=qtest")

ui/curses: Fix pageup/pagedown on -curses
Current KEY_NPAGE/KEY_PPAGE handling is broken on -curses. Those uses
"GREY", but "KEY_MASK" masked out "GREY".
To fix, we have to use correct mask value - SCANCODE_KEYMASK.
Then, this adds support of "shift + pageup/pagedown". With this,
-curses mode can use scroll-up/down as usual like other display modes.

ui/curses: Fix monitor color with -curses when 256 colors
If TERM=xterm-256color, COLOR_PAIRS==256 and monitor passes chtype
like 0x74xx. Then, the code uses uninitialized color pair. As result,
monitor uses black for both of fg and bg color, i.e. terminal is
filled by black.
To fix, this initialize above than 64 with default color (fg=white,bg=black).
FIXME: on 256 color, curses may be possible better vga color emulation.

* On the remaining messages, only the trailing newlines, "qemu:" and
"error:" message prefixes were removed.

file_ram_alloc: propagate error to caller instead of terminating QEMU
QEMU shouldn't exits from file_ram_alloc() if -mem-prealloc option is specified
and "object_add memory-backend-file,..." fails allocation during memory hotplug.
Propagate error to a caller and let it decide what to do with allocation failure.
That leaves QEMU alive if it can't create backend during hotplug time and
kills QEMU at startup time if backends or initial memory were misconfigured/
too large.

qapi: Reserve 'u' member name
Now that we have separated union tag values from colliding with
non-variant C names, by naming the union 'u', we should reserve
this name for our use. Note that we want to forbid 'u' even in
a struct with no variants, because it is possible for a future
qemu release to extend QMP in a backwards-compatible manner while
converting from a struct to a flat union. Fortunately, no
existing clients were using this member name. If we ever find
the need for QMP to have a member 'u', we could at that time
relax things, perhaps by having c_name() munge the QMP member to
'q_u'.
Note that we cannot forbid 'u' everywhere (by adding the
rejection code to check_name()), because the existing QKeyCode
enum already uses it; therefore we only reserve it as a struct
type member name.

qapi: Finish converting to new qapi union layout
We have two issues with our qapi union layout:
1) Even though the QMP wire format spells the tag 'type', the
C code spells it 'kind', requiring some hacks in the generator.
2) The C struct uses an anonymous union, which places all tag
values in the same namespace as all non-variant members. This
leads to spurious collisions if a tag value matches a non-variant
member's name.
This patch is the back end for a series that converts to a
saner qapi union layout. Now that all clients have been
converted to use 'type' and 'obj->u.value', we can drop the
temporary parallel support for 'kind' and 'obj->value'.
Given a simple union qapi type:
{ 'union':'Foo', 'data': { 'a':'int', 'b':'bool' } }
this is the overall effect, when compared to the state before
this series of patches:
| struct Foo {
|- FooKind kind;
|- union { /* union tag is @kind */
|+ FooKind type;
|+ union { /* union tag is @type */
| void *data;
| int64_t a;
| bool b;
|- };
|+ } u;
| };
The testsuite still contains some examples of artificial restrictions
(see flat-union-clash-type.json, for example) that are no longer
technically necessary, now that there is no longer a collision between
enum tag values and non-variant member names; but fixing this will be
done in later patches, in part because some further changes are required
to keep QAPISchema*.check() from asserting. Also, a later patch will
add a reservation for the member name 'u' to avoid a collision between a
user's non-variant names and our internal choice of C union name.
Note, however, that we do not rename the generated enum, which
is still 'FooKind'. A further patch could generate implicit
enums as 'FooType', but while the generator already reserved
the '*Kind' namespace (commit 4dc2e69), there are already QMP
constructs with '*Type' naming, which means changing our
reservation namespace would have lots of churn to C code to
deal with a forced name change.

tests: Convert to new qapi union layout
We have two issues with our qapi union layout:
1) Even though the QMP wire format spells the tag 'type', the
C code spells it 'kind', requiring some hacks in the generator.
2) The C struct uses an anonymous union, which places all tag
values in the same namespace as all non-variant members. This
leads to spurious collisions if a tag value matches a non-variant
member's name.
Make the conversion to the new layout for testsuite code.

qapi: Start converting to new qapi union layout
We have two issues with our qapi union layout:
1) Even though the QMP wire format spells the tag 'type', the
C code spells it 'kind', requiring some hacks in the generator.
2) The C struct uses an anonymous union, which places all tag
values in the same namespace as all non-variant members. This
leads to spurious collisions if a tag value matches a non-variant
member's name.
This patch is the front end for a series that converts to a
saner qapi union layout. By the end of the series, we will no
longer have the type/kind mismatch, and all tag values will be
under a named union, which requires clients to access
'obj->u.value' instead of 'obj->value'. But since the
conversion touches a number of files, it is easiest if we
temporarily support BOTH layouts simultaneously.
Given a simple union qapi type:
{ 'union':'Foo', 'data': { 'a':'int', 'b':'bool' } }
make the following changes in generated qapi-types.h:
| struct Foo {
|- FooKind kind;
|- union { /* union tag is @kind */
|+ union {
|+ FooKind kind;
|+ FooKind type;
|+ };
|+ union { /* union tag is @type */
| void *data;
| int64_t a;
| bool b;
|+ union { /* union tag is @type */
|+ void *data;
|+ int64_t a;
|+ bool b;
|+ } u;
| };
| };
Flat unions do not need the anonymous union for the tag member,
as we already fixed that to use the member name instead of 'kind'
back in commit 0f61af3e.
One additional change is needed in qapi.py: check_union() now
needs to check for collisions with 'type' in addition to those
with 'kind'.
Later, when the conversions are complete, we will remove the
duplication hacks, and also drop the check_union() restrictions.
Note, however, that we do not rename the generated enum, which
is still 'FooKind'. A further patch could generate implicit
enums as 'FooType', but while the generator already reserved
the '*Kind' namespace (commit 4dc2e69), there are already QMP
constructs with '*Type' naming, which means changing our
reservation namespace would have lots of churn to C code to
deal with a forced name change.

qapi-visit: Remove redundant functions for flat union base
The code for visiting the base class of a child struct created
visit_type_Base_fields() which covers all fields of Base; while
the code for visiting the base class of a flat union created
visit_type_Union_fields() covering all fields of the base
except the discriminator. But since the base class includes
the discriminator of a flat union, we can just visit the entire
base, without needing a separate visit of the discriminator.
Not only is consistently visiting all fields easier to
understand, it lets us share code.
The generated code in qapi-visit.c loses several now-unused
visit_type_UNION_fields(), along with changes like:
|@@ -1654,11 +1557,7 @@ void visit_type_BlockdevOptions(Visitor
| if (!*obj) {
| goto out_obj;
| }
|- visit_type_BlockdevOptions_fields(v, obj, &err);

|+ visit_type_BlockdevOptionsBase_fields(v, (BlockdevOptionsBase **)obj, &err);
| if (err) {
| goto out_obj;
| }
and forward declarations where needed. Note that the cast of obj
to BASE ** is necessary to call visit_type_BASE_fields() (and we
can't use our upcast wrappers, because those work on pointers while
we have a pointer-to-pointer).

qapi: Unbox base members
Rather than storing a base class as a pointer to a box, just
store the fields of that base class in the same order, so that
a child struct can be directly cast to its parent. This gives
less malloc overhead, less pointer dereferencing, and even less
generated code. Compare to the earlier commit 1e6c1616a "qapi:
Generate a nicer struct for flat unions" (although that patch
had fewer places to change, as less of qemu was directly using
qapi structs for flat unions). It also allows us to turn on
automatic type-safe wrappers for upcasting to the base class
of a struct.
Changes to the generated code look like this in qapi-types.h:
| struct SpiceChannel {
|- SpiceBasicInfo *base;
|+ /* Members inherited from SpiceBasicInfo: */
|+ char *host;
|+ char *port;
|+ NetworkAddressFamily family;
|+ /* Own members: */
| int64_t connection_id;
as well as additional upcast functions like qapi_SpiceChannel_base().
Meanwhile, changes to qapi-visit.c look like:
| static void visit_type_SpiceChannel_fields(Visitor *v, SpiceChannel **obj, Error **errp)
| {
| Error *err = NULL;
|
|- visit_type_implicit_SpiceBasicInfo(v, &(*obj)->base, &err);
|+ visit_type_SpiceBasicInfo_fields(v, (SpiceBasicInfo **)obj, &err);
| if (err) {
(the cast is necessary, since our upcast wrappers only deal with a
single pointer, not pointer-to-pointer); plus the wholesale
elimination of some now-unused visit_type_implicit_FOO() functions.
Without boxing, the corner case of one empty struct having
another empty struct as its base type now requires inserting a
dummy member (previously, the 'Base *base' member sufficed).
And now that we no longer consume a 'base' member in the generated
C struct, we can delete the former negative struct-base-clash-base
test.

qapi: Prefer typesafe upcasts to qapi base classes
A previous patch (commit 1e6c1616) made it possible to
directly cast from a qapi flat union type to its base type.
However, it requires the use of a C cast, which turns off
compiler type-safety checks. Fortunately, no such casts
exist, just yet.
Regardless, add inline type-safe wrappers named
qapi_FOO_base() for any union type FOO that has a base,
which can be used for a safer upcast, and enhance the
testsuite to cover the new functionality.
A future patch will extend the upcast support to structs,
where such conversions do exist already.
Note that C makes const-correct upcasts annoying because
it lacks overloads; these functions cast away const so that
they can accept user pointers whether const or not, and the
result in turn can be assigned to normal or const pointers.
Alternatively, this could have been done with macros, but
type-safe macros are hairy, and not worthwhile here.
This patch just adds upcasts. None of our code needed to
downcast from a base qapi class to a child. Also, in the
case of grandchildren (such as BlockdevOptionsQcow2), the
caller will need to call two functions to get to the inner
base (although it wouldn't be too hard to generate a
qapi_FOO_base_base() if desired). If a user changes qapi
to alter the base class hierarchy, such as going from
'A -> C' to 'A -> B -> C', it will change the type of
'qapi_C_base()', and the compiler will point out the places
that are affected by the new base.
One alternative was proposed, but was deemed too ugly to use
in practice: the generators could output redundant
information using anonymous types:
| struct Child {
| union {
| struct {
| Type1 parent_member1;
| Type2 parent_member2;
| };
| Parent base;
| };
| };
With that ugly proposal, for a given qapi type, obj->member
and obj->base.member would refer to the same storage; allowing
convenience in working with members without needing 'base.'
allowing typesafe upcast without needing a C cast by accessing
'&obj->base', and allowing downcasts from the parent back to
the child possible through container_of(obj, Child, base).

A future qapi patch will rework generated structs with a base
class to be unboxed. In preparation for that, change the code
that allocates then populates an info struct to instead merely
populate the fields of an info field passed in as a parameter
(renaming vnc_basic_info_get* to vnc_init_basic_info*). Add
rudimentary Error handling at the lowest levels for cases
where the old code returned NULL; but rather than plumb Error
all the way through the stack, the callers drop the error and
return NULL as before.

qapi: Reserve 'q_*' and 'has_*' member names
c_name() produces names starting with 'q_' when protecting a
dictionary member name that would fail to directly compile, but
in doing so can cause clashes with any member name already
beginning with 'q-' or 'q_'. Likewise, we create a C name 'has_'
for any optional member that can clash with any member name
beginning with 'has-' or 'has_'.
Technically, rather than blindly reserving the namespace,
we could try to complain about user names only when an actual
collision occurs, or even teach c_name() how to munge names
to avoid collisions. But it is not trivial, especially when
collisions can occur across multiple types (such as via
inheritance or flat unions). Besides, no existing .json
files are trying to use these names. So it's easier to just
outright forbid the potential for collision. We can always
relax things in the future if a real need arises for QMP to
express member names that have been forbidden here.
'has_' only has to be reserved for struct/union member names,
while 'q_' is reserved everywhere (matching the fact that
only members can be optional, while we use c_name() for munging
both members and entities). Note that we could relax 'q_'
restrictions on entities independently from member names; for
example, c_name('qmp_' + 'unix') would result in a different
function name than our current 'qmp_' + c_name('unix').
Update and add tests to cover the new error messages.

qapi: More robust conditions for when labels are needed
We were using regular expressions to see if ret included
any earlier text that emitted a 'goto out;' line, to decide
whether we needed to output an 'out:' label. But this is
fragile, if the ret text can possibly combine more than one
generated function body, where the first function used a
goto but the second does not. Change the code to just check
for the known conditions which cause an error check to be
needed. Besides, it's slightly more efficient to use plain
checks than regular expression searching.

tests/qapi-schema: Test for reserved names, empty struct
Add some testsuite coverage to ensure future patches are on
the right track:
Our current C representation of qapi arrays is done by appending
'List' to the element name; but we are not preventing the
creation of an object type with the same name. Add
reserved-type-list.json to test this. Then rename
enum-union-clash.json to reserved-type-kind.json to cover the
reservation that we DO detect, and shorten it to match the fact
that the name is reserved even if there is no clash.
We are failing to detect a collision between a dictionary member
and the implicit 'has_*' flag for another optional member. The
easiest fix would be for a future patch to reserve the entire
"has[-_]" namespace for member names (the collision is also
possible for branch names within flat unions, but only as long as
branch names can collide with (non-variant) members; however,
since future patches are about to remove that, it is not worth
testing here). Add reserved-member-has.json to test this.
A similar collision exists between a dictionary member where
c_name() munges what might otherwise be a reserved name to start
with 'q_', and another member explicitly starts with "q[-_]".
Again, the easiest solution for a future patch will be reserving
the entire namespace, but here for commands as well as members.
Add reserved-member-q.json and reserved-command-q.json to test
this; separate tests since arguably our munging of command 'unix'
to 'qmp_q_unix()' could be done without a q_, which is different
than the munging of a member 'unix' to 'foo.q_unix'.
Finally, our testsuite does not have any compilation coverage
of struct inheritance with empty qapi structs. Update
qapi-schema-test.json to test this.
Note that there is currently no technical reason to forbid type
name patterns from member names, or member name patterns from
types, since the two are not in the same namespace in C and
won't collide; but it's not worth adding positive tests of these
corner cases at this time, especially while there is other churn
pending in patches that rearrange which collisions actually
happen.

target-mips: fix updating XContext on mmu exception
Correct updating XContext.Region field on mmu exceptions.
If Config3.CTXTC = 0 then the R field of XContext has to be updated
with the value of bits 63..62 of the virtual address upon a TLB
exception.
Also fixed the below line which overs 80 characters.

hw/mips_malta: Fix KVM PC initialisation
Commit 71c199c81d29 ("mips_malta: provide ememsize env variable to
kernels") changed the meaning of loaderparams.ram_size to be the whole
of RAM rather than just the low part below where the boot code is placed
for KVM, but it didn't update the PC initialisation for KVM to use
ram_low_size. Fix that now.

monitor: Throttle event VSERPORT_CHANGE separately by "id"
VSERPORT_CHANGE is emitted when the guest opens or closes a
virtio-serial port. The event's member "id" identifies the port.
When several events arrive quickly, throttling drops all but the last
of them. Because of that, a QMP client must assume that *any* port
may have changed state when it receives a VSERPORT_CHANGE event and
throttling may have happened.
Make the event more useful by throttling it for each port separately.

these two explicit recursions by a loop recursing for all child nodes.

virtio: sync the dataplane vring state to the virtqueue before virtio_save
When creating snapshot with the dataplane enabled, the snapshot file gets
not the actual state of virtqueue, because the current state is stored in
VirtIOBlockDataPlane. Therefore, before saving snapshot need to sync
the dataplane vring state to the virtqueue. The dataplane will resume its
work at the next notify virtqueue.
When snapshot loads with loadvm we get a message:
VQ 0 size 0x80 Guest index 0x15f5 inconsistent with Host index 0x0:
delta 0x15f5
error while loading state for instance 0x0 of device
'0000:00:08.0/virtio-blk'
Error -1 while loading VM state
to reproduce the error I used the following hmp commands:
savevm snap1
loadvm snap1

Devices that are compliant with virtio-1 do not support scsi

qemu-gdb: allow using glibc_pointer_guard() on core dumps
get_fs_base() cannot be run on a core dump, because it uses the arch_prctl
system call. The fs base is the value that is returned by pthread_self(),
and it would be nice to just glean it from the "info threads" output:
* 1 Thread 0x7f16a3fff700 (LWP 33642) pthread_cond_wait@@GLIBC_2.3.2 ()
^^^^^^^^^^^^^^
but unfortunately the gdb API does not provide that. Instead, we can
look for the "arg" argument of the start_thread function if glibc debug
information are available. If not, fall back to the old mechanism.

The event throttling state machine is hard to understand. I'm not
sure it's entirely correct. Rewrite it in a more straightforward
manner:
State 1: No event sent recently (less than evconf->rate ns ago)
Invariant: evstate->timer is not pending, evstate->qdict is null
On event: send event, arm timer, goto state 2
State 2: Event sent recently, no additional event being delayed
Invariant: evstate->timer is pending, evstate->qdict is null
On event: store it in evstate->qdict, goto state 3
On timer: goto state 1
State 3: Event sent recently, additional event being delayed
Invariant: evstate->timer is pending, evstate->qdict is non-null
On event: store it in evstate->qdict, goto state 3
On timer: send evstate->qdict, clear evstate->qdict,
arm timer, goto state 2

New features:
This enables hotplug for multifunction devices.
Patches are very small, so I think it's OK to merge
at this stage.
There's also some new infrastructure for vhost-user testing
not enabled yet so it's harmless to merge.
I've reverted the "gap between DIMMs" workaround, as it seems too risky, and
applied my own patch in virtio, but not in dataplane code. This means that
dataplane is broken for some complex DIMM configurations for now. Waiting for

tests/vhost-user-bridge: add vhost-user bridge application
The test existing in QEMU for vhost-user feature is good for
testing the management protocol, but does not allow actual
traffic. This patch proposes Vhost-User Bridge application, which
can serve the QEMU community as a comprehensive test by running
real internet traffic by means of vhost-user interface.
Essentially the Vhost-User Bridge is a very basic vhost-user
backend for QEMU. It runs as a standalone user-level process.
For packet processing Vhost-User Bridge uses an additional QEMU
instance with a backend configured by "-net socket" as a shared
VLAN. This way another QEMU virtual machine can effectively
serve as a shared bus by means of UDP communication.
For a more simple setup, the another QEMU instance running the
SLiRP backend can be the same QEMU instance running vhost-user
client.
This Vhost-User Bridge implementation is very preliminary. It is
missing many features. I has been studying vhost-user protocol
internals, so I've written vhost-user-bridge bit by bit as I
progressed through the protocol. Most probably its internal
architecture will change significantly.
To run Vhost-User Bridge application:
1. Build vhost-user-bridge with a regular procedure. This will
create a vhost-user-bridge executable under tests directory:
$ configure; make tests/vhost-user-bridge
2. Ensure the machine has hugepages enabled in kernel with
command line like:
default_hugepagesz=2M hugepagesz=2M hugepages=2048
3. Run Vhost-User Bridge with:
$ tests/vhost-user-bridge
The above will run vhost-user server listening for connections
on UNIX domain socket /tmp/vubr.sock, and will try to connect
by UDP to VLAN bridge to localhost:5555, while listening on
localhost:4444
Run qemu with a virtio-net backed by vhost-user:
$ qemu \
-enable-kvm -m 512 -smp 2 \
-object memory-backend-file,id=mem,size=512M,mem-path=/dev/hugepages,share=on \
-numa node,memdev=mem -mem-prealloc \
-chardev socket,id=char0,path=/tmp/vubr.sock \
-netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce \
-device virtio-net-pci,netdev=mynet1 \
-net none \
-net socket,vlan=0,udp=localhost:4444,localaddr=localhost:5555 \
-net user,vlan=0 \
disk.img
vhost-user-bridge was tested very lightly: it's able to bringup a
linux on client VM with the virtio-net driver, and execute transmits
and receives to the internet. I tested with "wget redhat.com",
"dig redhat.com".
PS. I've consulted DPDK's code for vhost-user during Vhost-User
Bridge implementation.

virtio: introduce virtio_map
virtio_map_sg currently fails if one of the entries it's mapping is
contigious in GPA but not HVA address space. Introduce virtio_map which
handles this by splitting sg entries.
This new API generally turns out to be a good idea since it's harder to
misuse: at least in one case the existing one was used incorrectly.
This will still fail if there's no space left in the sg, but luckily max
queue size in use is currently 256, while max sg size is 1024, so we
should be OK even is all entries happen to cross a single DIMM boundary.
Won't work well with very small DIMM sizes, unfortunately:
e.g. this will fail with 4K DIMMs where a single
request might span a large number of DIMMs.
Let's hope these are uncommon - at least we are not breaking things.
Note: virtio-scsi calls virtio_map_sg on data loaded from network, and
validates input, asserting on failure. Copy the validating code here -
it will be dropped from virtio-scsi in a follow-up patch.

pc: memhp: do not emit inserting event for coldplugged DIMMs
currently acpi_memory_plug_cb() sets is_inserting for
cold- and hot-plugged DIMMs as result ASL MHPD.MSCN()
method issues device check even for every coldplugged
DIMM. There isn't much harm in it but if we try to
unplug such DIMM, OSPM will issue device check
intstead of device eject event. So OSPM won't eject
memory module as expected and it will try to eject it
only when another memory device is hot-(un)plugged.
As a fix do not set 'is_inserting' event and do not
issue SCI for cold-plugged DIMMs as they are
enumerated and activated by OSPM during guest's boot.

target-i386: Enable "check" mode by default
Current default behavior of QEMU is to silently disable features that
are not supported by the host when a CPU model is requested in the
command-line. This means that in addition to risking breaking guest ABI
by default, we are silent about it.
I would like to enable "enforce" by default, but this can easily break
existing production systems because of the way libvirt makes assumptions
about CPU models today (this will change in the future, once QEMU
provide a proper interface for checking if a CPU model is runnable).
But there's no reason we should be silent about it. So, change
target-i386 to enable "check" mode by default so at least we have some
warning printed to stderr (and hopefully logged somewhere) when QEMU
disables a feature that is not supported by the host system.

target-i386: Don't left shift negative constant
Left shift of negative values is undefined behavior. Detected by clang:
qemu/target-i386/translate.c:2423:26: runtime error:

This changes the code to reverse the sign after the left shift.

hw/arm/virt: don't use a15memmap directly
We should always go through VirtBoardInfo when we need the memmap.
To avoid using a15memmap directly, in this case, we need to defer
the max-cpus check from class init time to instance init time. In
class init we now use MAX_CPUMASK_BITS for max_cpus initialization,
which is the maximum QEMU supports, and also, incidentally, the
maximum KVM/gicv3 currently supports. Also, a nice side-effect of
delaying the max-cpus check is that we now get more appropriate
error messages for gicv2 machines that try to configure more than
123 cpus. Before this patch it would complain that the requested
number of cpus was greater than 123, but for gicv2 configs, it
should complain that the number is greater than 8.

target-arm/translate.c: Handle non-executable page-straddling Thumb insns
When the memory we're trying to translate code from is not executable we have
to turn this into a guest fault. In order to report the correct PC for this
fault, and to make sure it is not reported until after any other possible
faults for instructions earlier in execution, we must terminate TBs at
the end of a page, in case the next instruction is in a non-executable page.
This is simple for T16, A32 and A64 instructions, which are always aligned
to their size. However T32 instructions may be 32-bits but only 16-aligned,
so they can straddle a page boundary.

target-arm: Fix "no 64-bit EL2" assumption in arm_excp_unmasked()
The code in arm_excp_unmasked() suppresses the ability of PSTATE.AIF
to mask exceptions from a lower EL targeting EL2 or EL3 if the
CPU is 64-bit. This is correct for a target of EL3, but not correct
for targeting EL2. Further, we go to some effort to calculate
scr and hcr values which are not used at all for the 64-bit CPU
case.
Rearrange the code to correctly implement the 64-bit CPU logic
and keep the hcr/scr calculations in the 32-bit CPU codepath.

net: Remove duplicate data from query-rx-filter on multiqueue net devices
When responding to a query-rx-filter command on a multiqueue
netdev, qemu reports the data for each queue. The data, however,
is not per-queue, but per device and the same data is reported
multiple times. This causes confusion and may also cause extra
unnecessary processing when looking at the data.
Commit 638fb14169 (net: Make qmp_query_rx_filter() with name argument
more obvious) partially addresses this issue, by limiting the output
when the name is specified. However, when the name is not specified,
the issue still persists.

vmxnet3: Do not fill stats if device is inactive
Guest OS may issue VMXNET3_CMD_GET_STATS even before device was
activated (for example in linux, after insmod but prior net-dev open).
Accessing shared descriptors prior device activation is illegal as the
VMXNET3State structures have not been fully initialized.
As a result, guest memory gets corrupted and may lead to guest OS
crashes.
Fix, by not filling the stats descriptors if device is inactive.

Qemu/Xen: Fix early freeing MSIX MMIO memory region
msix->mmio is added to XenPCIPassthroughState's object as property.
object_finalize_child_property is called for XenPCIPassthroughState's
object, which calls object_property_del_all, which is going to try to
delete msix->mmio. object_finalize_child_property() will access
msix->mmio's obj. But the whole msix struct has already been freed
by xen_pt_msix_delete. This will cause segment fault when msix->mmio
has been overwritten.
This patch is to fix the issue.

ivshmem: use little-endian int64_t for the protocol
The current ivshmem protocol uses 'long' for integers. But the
sizeof(long) depends on the host and the endianess is not defined, which
may cause portability troubles.
Instead, switch to using little-endian int64_t. This breaks the
protocol, except on x64 little-endian host where this change
should be compatible.

ivshmem: add check on protocol version in QEMU
Send a protocol version as the first message from server, clients must
close communication if they don't support this protocol version. Older
QEMUs should be fine with this change in the protocol since they
overrides their own vm_id on reception of an id associated to no
eventfd.

block: Add "drained begin/end" for transactional backup
This ensures the atomicity of the transaction by avoiding processing of
external requests such as those from ioeventfd.
Move the assignment to state->bs up right after bdrv_drained_begin, so
that we can use it in the clean callback. The abort callback will still
check bs->job and state->job, so it's OK.

The group throttling code was always meant to handle its locking

Now that bdrv_swap() no longer exists there's no need for the

If there is no BlockDriverState in a BlockBackend or if the tray of the

The reason the status of the guest device is taken into account is
because once the guest device's tray is opened, any request on the same
BlockBackend as the guest uses should fail. If the BDS tree is supposed
to be usable even after ejecting it from the guest, a different

block/throttle-groups: Make incref/decref public
Throttle groups are not necessarily referenced by BDSs alone; a later
patch will essentially allow BBs to reference them, too. Make the
ref/unref functions public so that reference can be properly accounted
for.
Their interface is slightly adjusted in that they return and take a
ThrottleState pointer, respectively, instead of a ThrottleGroup pointer.
Functionally, they are equivalent, but since ThrottleGroup is not meant
to be used outside of block/throttle-groups.c, ThrottleState is easier
to handle.

block: Remove wr_highest_sector from BlockAcctStats
BlockAcctStats contains statistics about the data transferred from and
to the device; wr_highest_sector does not fit in with the rest.
Furthermore, those statistics are supposed to be specific for a certain
device and not necessarily for a BDS (see the comment above
bdrv_get_stats()); on the other hand, wr_highest_sector may be a rather
important information to know for each BDS. When BlockAcctStats is
finally removed from the BDS, we will want to keep wr_highest_sector in
the BDS.
Finally, wr_highest_sector is renamed to wr_highest_offset and given the
appropriate meaning. Externally, it is represented as an offset so there
is no point in doing something different internally. Its definition is
changed to match that in qapi/block-core.json which is "the offset after
the greatest byte written to". Doing so should not cause any harm since
if external programs tried to calculate the volume usage by
(wr_highest_offset + 512) / volume_size, after this patch they will just
assume the volume to be full slightly earlier than before.

block: Fix BB AIOCB AioContext without BDS
Fix the BlockBackend's AIOCB AioContext for aborting AIO in case there
is no BDS. If there is no implementation of AIOCBInfo::get_aio_context()
the AioContext is derived from the BDS the AIOCB belongs to. If that BDS
is NULL (because it has been removed from the BB) this will not work.
This patch makes blk_get_aio_context() fall back to the main loop
context if the BDS pointer is NULL and implements
AIOCBInfo::get_aio_context() (blk_aiocb_get_aio_context()) which invokes
blk_get_aio_context().

QGA skips pseudo-filesystems when querying filesystems via
guest-get-fsinfo. On some hosts, such as travis-ci which uses
containers with simfs filesystems, QGA might not report *any*
filesystems. Our test case assumes there would be at least one,
leading to false error messages in these situations.
Instead, sanity-check values iff we get at least one filesystem.

spapr_pci: Allow VFIO devices to work on the normal PCI host bridge
The core VFIO infrastructure more or less allows VFIO devices to work
on any normal guest PCI host bridge (PHB) without extra logic.
However, the "spapr-pci-host-bridge" device (as opposed to the special
"spapr-pci-vfio-host-bridge" device) breaks this by using a partially
KVM accelerated implementation of the guest kernel IOMMU which won't
work with VFIO devices, without additional kernel support.
This patch allows VFIO devices to work on the spapr-pci-host-bridge,
by having it switch off KVM TCE acceleration when a VFIO device is
added to the PHB (either on startup, or by hotplug).

spapr_iommu: Provide a function to switch a TCE table to allowing VFIO
Because of the way non-VFIO guest IOMMU operations are KVM accelerated, not
all TCE tables (guest IOMMU contexts) can support VFIO devices. Currently,
this is decided at creation time.
To support hotplug of VFIO devices, we need to allow a TCE table which
previously didn't allow VFIO devices to be switched so that it can. This
patch adds an spapr_tce_set_need_vfio() function to do this, by
reallocating the table in userspace if necessary.
Currently this doesn't allow the KVM acceleration to be re-enabled if all
the VFIO devices are removed. That's an optimization for another time.

spapr_iommu: Rename vfio_accel parameter
The vfio_accel parameter used when creating a new TCE table (guest IOMMU
context) has a confusing name. What it really means is whether we need the
TCE table created to be able to support VFIO devices.
VFIO is relevant, because when available we use in-kernel acceleration of
the TCE table, but that may not work with VFIO devices because updates to
the table are handled in kernel, bypass qemu and so don't hit qemu's
infrastructure for keeping the VFIO host IOMMU state in sync with the guest
IOMMU state.
Rename the parameter to "need_vfio" throughout. This is a cosmetic change,
with no impact on the logic.

spapr_pci: Allow PCI host bridge DMA window to be configured
At present the PCI host bridge (PHB) for the pseries machine type has a
fixed DMA window from 0..1GB (in PCI address space) which is mapped to real
memory via the PAPR paravirtualized IOMMU.
For better support of VFIO devices, we're going to want to allow for
different configurations of the DMA window.
Eventually we'll want to allow the guest itself to reconfigure the window
via the PAPR dynamic DMA window interface, but as a preliminary this patch

spapr: Add "slb-size" property to CPU device tree nodes
According to a commit message in the Linux kernel (see here
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b60c31d85a2a
for example), the name of the property that carries the information
about the number of SLB entries should be called "slb-size", and
not "ibm,slb-size". The Linux kernel can deal with both names, but
to be on the safe side we should support the official name, too.
[Now that LoPAPR is public, the relevant requirement can be found in
section C.6.1.8 --dwg]

spapr: Abort when HTAB of requested size isn't allocated
Terminate the guest when HTAB of requested size isn't allocated by
the host.
When memory hotplug is attempted on a guest that has booted with
less than requested HTAB size, the guest kernel will not be able
to gracefully fail the hotplug request. This patch will ensure that
we never end up in a situation where memory hotplug fails due to
less than requested HTAB size.

crypto: add sanity checking of TLS x509 credentials
defined new variables $TEST_LIBS and $TEST_CFLAGS and
used them in tests/Makefile to augment $LIBS and $CFLAGS.
Unfortunately this overlooks the fact that tests/Makefile
is not executed via recursive-make, it is just pulled into
the top level Makefile via an include statement. So rather
than just augmenting the compiler/linker flags for tests
it polluted the global flags.
This is thought to be behind a reported failure when
building the pixman module as a sub-module, since global
$CFLAGS are passed down to configure in pixman.
This change removes the $TEST_LIBS and $TEST_CFLAGS
replacing them with $TASN1_LIBS and $TASN1_CFLAGS,
setting only against specific objects/executables
that need them.

crypto: allow use of nettle/gcrypt to be selected explicitly
Currently the choice of whether to use nettle or gcrypt is
made based on what gnutls is linked to. There are times
when it is desirable to be able to force build against a
specific library. For example, if testing changes to QEMU's
crypto code all 3 possible backends need to be checked
regardless of what the local gnutls uses.
It is also desirable to be able to enable nettle/gcrypt
for cipher/hash algorithms, without enabling gnutls
for TLS support.
This gives two new configure flags, which allow the
following possibilities
Automatically determine nettle vs gcrypt from what
gnutls links to (recommended to minimize number of
crypto libraries linked to)
./configure
Automatically determine nettle vs gcrypt based on
which is installed
./configure --disable-gnutls
Force use of nettle
./configure --enable-nettle
Force use of gcrypt
./configure --enable-gcrypt
Force use of built-in AES & crippled-DES
./configure --disable-nettle --disable-gcrypt

hw/isa/lpc_ich9: inject the SMI on the VCPU that is writing to APM_CNT
Commit 4d00636e97b7 ("ich9: Add the lpc chip", Nov 14 2012) added the
ich9_apm_ctrl_changed() ioport write callback function such that it would
inject the SMI, in response to a write to the APM_CNT register, on the
first CPU, invariably.
Since this register is used by guest code to trigger an SMI synchronously,
the interrupt should be injected on the VCPU that is performing the write.
apm_ioport_writeb() is the .write callback of the "apm_ops"
MemoryRegionOps [hw/isa/apm.c]; it is parametrized to call
ich9_apm_ctrl_changed() by ich9_lpc_init() [hw/isa/lpc_ich9.c], via
apm_init(). Therefore this change affects no other board.
ich9_generate_smi() is an unrelated function that is called by the TCO
watchdog; a watchdog is likely in its right to (asynchronously) inject
interrupts on the first CPU only.
This patch allows the combined edk2/OVMF SMM driver stack to work with
multiple VCPUs on TCG, using both qemu-system-i386 and qemu-system-x86_64.

vhost: set the correct queue index in case of migration with multiqueue
When a live migration is started the log address to mark dirty pages is provided
to the vhost backend through the vhost_dev_set_log function.
This function is called for each queue pairs but the queue index is wrongly set:
always set to the first queue pair. Then vhost backend lost descriptor addresses
of the queue pairs greater than 1 and behaviour of the vhost backend is
unpredictable.
The queue index is computed by taking account of the vq_index (to retrieve the
queue pair index) and calling the vhost_get_vq_index method of the backend.

vhost user: add rarp sending after live migration for legacy guest
A new vhost user message is added to allow QEMU to ask to vhost user backend to
broadcast a fake RARP after live migration for guest without GUEST_ANNOUNCE
capability.
This new message is sent only if the backend supports the new
VHOST_USER_PROTOCOL_F_RARP protocol feature.
The payload of this new message is the MAC address of the guest (not known by
the backend). The MAC address is copied in the first 6 bytes of a u64 to avoid
to create a new payload message type.
This new message has no equivalent ioctl so a new callback is added in the
userOps structure to send the request.
Upon reception of this new message the vhost user backend must generate and
broadcast a fake RARP request to notify the migration is terminated.

vhost user: add support of live migration
Some vhost user backends are able to support live migration.
To provide this service the following features must be added:
1. Add the VIRTIO_NET_F_GUEST_ANNOUNCE capability to vhost-net when netdev
backend is vhost-user.
2. Provide a nop receive callback to vhost-user.
This callback is called by:
* qemu_announce_self after a migration to send fake RARP to avoid network
outage for peers talking to the migrated guest.
- For guest with GUEST_ANNOUNCE capabilities, guest already sends GARP
when the bit VIRTIO_NET_S_ANNOUNCE is set.
=> These packets must be discarded.
- For guest without GUEST_ANNOUNCE capabilities, migration termination
is notified when the guest sends packets.
=> These packets can be discarded.
* virtio_net_tx_bh with a dummy boot to send fake bootp/dhcp request.
BIOS guest manages virtio driver to send 4 bootp/dhcp request in case of
dummy boot.
=> These packets must be discarded.

util: add linux-only memfd fallback
Implement memfd_create() fallback if not available in system libc.
memfd_create() is still not included in glibc today, atlhough it's been
available since Linux 3.17 in Oct 2014.
memfd has numerous advantages over traditional shm/mmap for ipc memory
sharing with fd handler, which we are going to make use of for
vhost-user logging memory in following patches.
The next patches are going to introduce helpers to use best practices of
memfd usage and provide some compatibility fallback. memfd.c is thus
temporarily useless and eventually empty if memfd_create() is provided
by the system.

s390x: reset crypto only on clear reset and QEMU reset
Initializing VM crypto in initial cpu reset has multiple problems
1. We call the exact same function #VCPU times, although one time is enough
2. On SIGP initial cpu reset, we exchange the wrapping key while
other VCPUs are running. Bad!
3. It is simply wrong. According to the Pop, a reset happens only during a
clear reset.
So, we have to reset the keys
- on modified clear reset

s390x: machine reset function with new ipl cpu handling
Current implementation depends on the order of resets getting triggered.
If a cpu reset is triggered after the ipl device reset, the CPU is stopped and
the VM will not run. In fact, that hinders us from converting the ipl device
into a TYPE_DEVICE. Let's change that by manually configuring the ipl cpu
during a system reset, so we have full control and can demangle that code.
Also remove the superflous cpu parameter from s390_update_iplstate on the way.

net: don't set native endianness
commit 5be7d9f1b1452613b95c6ba70b8d7ad3d0797991
vhost-net: tell tap backend about the vnet endianness
makes vhost net always try to set LE - even if that matches the
native endian-ness.
This makes it fail on older kernels on x86 without TUNSETVNETLE support.
To fix, make qemu_set_vnet_le/qemu_set_vnet_be skip the
ioctl if it matches the host endian-ness.

s390x/kvm: Fix vector validity bit in device machine checks
Device hotplugs trigger a crw machine check. All machine checks
have validity bits for certain register types. With vector support
we also have to claim that vector registers are valid.
This is a band-aid suitable for stable. Long term we should
create the full mcic value dynamically depending on the active
features in the kernel interrupt handler.

coroutine: move into libqemuutil.a library
The coroutine files are currently referenced by the block-obj-y
variable. The coroutine functionality though is already used by
more than just the block code. eg migration code uses coroutine
yield. In the future the I/O channel code will also use the
coroutine yield functionality. Since the coroutine code is nicely
self-contained it can be easily built as part of the libqemuutil.a
library, making it widely available.
The headers are also moved into include/qemu, instead of the
include/block directory, since they are now part of the util
codebase, and the impl was never in the block/ directory
either.

osdep: add qemu_fork() wrapper for safely handling signals
When using regular fork() the child process of course inherits
all the parents' signal handlers. If the child then proceeds
to close() any open file descriptors, it may break some of those
registered signal handlers. The child generally does not want to
ever run any of the signal handlers that the parent may have
installed in the short time before it exec's. The parent may also
have blocked various signals which the child process will want
enabled.
This introduces a wrapper qemu_fork() that takes care to sanitize
signal handling across fork. Before forking it blocks all signals
in the parent thread. After fork returns, the parent unblocks the
signals and carries on as usual. The child, however, resets all the
signal handlers back to their defaults before it unblocks signals.
The child process can now exec the binary in a "clean" signal
environment.

qga: guest-exec simple stdin/stdout/stderr redirection
Implemented with base64-encoded strings in qga json protocol.
Glib portable GIOChannel is used for data I/O.
Optinal stdin parameter of guest-exec command is now used as
stdin content for spawned subprocess.
If capture-output bool flag is specified, guest-exec redirects out/err
file descriptiors internally to pipes and collects subprocess
output.
Guest-exe-status is modified to return this collected data to requestor
in base64 encoding.

qga: guest exec functionality
Guest-exec rewritten in platform-independent style with glib spawn.
Child process is spawn asynchronously and exit status can later
be picked up by guest-exec-status command.
stdin/stdout/stderr of the child now is redirected to /dev/null
Later we will add ability to specify stdin in guest-exec command
and to get collected stdout/stderr with guest-exec-status.

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,

Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

build: qemu-ga: add 'qemu-ga' build target for w32
Currently POSIX builds rely on 'qemu-ga' target to do qga-only
distributable build. On w32, as with most standalone binary targets,
we rely on 'qemu-ga.exe' target.
Unlike with POSIX, qemu-ga for w32 has a number of related targets
such as VSS DLL and MSI package. We can do the full distributable
qga-only build on w32 with:
make qemu-ga.exe
or:
make msi
To make that work, we tie VSS dependencies onto qemu-ga.exe.
However, in reality the DLL isn't part of the binary, so we use a
filter to pull them out of the LINK recipe, which attempts to link
against prereqs for binary targets. Additionally, it could be argued
that VSS is a separate distributable, and shouldn't be implied by
qemu-ga.exe binary target.
To avoid this, we can tie the VSS dependencies only to the 'msi'
target, but that would make it impossible to do a qga-only build of
the w32 distributable without building the 'msi' package, which was
supported in the past.
An alternative approach is to add a new target to build the whole
distributable. w32 allows us to use the same build target we use
on POSIX, 'qemu-ga', since the current binary-only target on w32
is 'qemu-ga.exe'.
To further simplify the build, we also make 'qemu-ga' build the MSI
package if the appropriate ./configure options are set, making the
full qga-only build the same on both POSIX and w32: `make qemu-ga`

tcg/mips: Support r6 SEL{NE, EQ}Z instead of MOVN/MOVZ
Extend MIPS movcond implementation to support the SELNEZ/SELEQZ
instructions introduced in MIPS r6 (where MOVN/MOVZ have been removed).
Whereas the "MOVN/MOVZ rd, rs, rt" instructions have the following
semantics:
rd = [!]rt ? rs : rd
The "SELNEZ/SELEQZ rd, rs, rt" instructions are slightly different:
rd = [!]rt ? rs : 0
First we ensure that if one of the movcond input values is zero that it
comes last (we can swap the input arguments if we invert the condition).
This is so that it can exactly match one of the SELNEZ/SELEQZ
instructions and avoid the need to emit the other one.
Otherwise we emit the opposite instruction first into a temporary
register, and OR that into the result:
SELNEZ/SELEQZ TMP1, v2, c1
SELEQZ/SELNEZ ret, v1, c1
OR ret, ret, TMP1
Which does the following:
ret = cond ? v1 : v2

tcg/mips: Support r6 multiply/divide encodings
MIPSr6 adds several new integer multiply, divide, and modulo
instructions, and removes several pre-r6 encodings, along with the HI/LO
registers which were the implicit operands of some of those
instructions. Update TCG to use the new instructions when built for r6.
The new instructions actually map much more directly to the TCG ops, as
they only provide a single 32-bit half of the result and in a normal
general purpose register instead of HI or LO.
The mulu2_i32 and muls2_i32 operations are no longer appropriate for r6,
so they are removed from the TCG opcode table. This is because they
would need to emit two separate host instructions anyway (for the high
and low half of the result), which TCG can arrange automatically for us
in the absense of mulu2_i32/muls2_i32 by splitting it into mul_i32 and
mul*h_i32 TCG ops.

kvm: Allow the Hyper-V vendor ID to be specified
According to Microsoft documentation, the signature in the standard
hypervisor CPUID leaf at 0x40000000 identifies the Vendor ID and is
for reporting and diagnostic purposes only. We can therefore allow
the user to change it to whatever they want, within the 12 character
limit. Add a new hv-vendor-id option to the -cpu flag to allow
for this, ex:
-cpu host,hv_time,hv-vendor-id=KeenlyKVM

kvm: Pass PCI device pointer to MSI routing functions
In-kernel ITS emulation on ARM64 will require to supply requester IDs.
These IDs can now be retrieved from the device pointer using new
pci_requester_id() function.
This patch adds pci_dev pointer to KVM GSI routing functions and makes
callers passing it.
x86 architecture does not use requester IDs, but hw/i386/kvm/pci-assign.c
also made passing PCI device pointer instead of NULL for consistency with
the rest of the code.

hw/pci: Introduce pci_requester_id()
For GICv3 ITS implementation we are going to use requester IDs in KVM IRQ
routing code. This patch introduces reusable convenient way to obtain this
ID from the device pointer. The new function is now used in some places,
where the same calculation was used.
MemTxAttrs.stream_id also renamed to requester_id in order to better

intel_iommu: Add support for translation for devices behind bridges
- Use a hash table indexed on bus pointers to store information about buses
instead of using the bus numbers.
Bus pointers are stored in a new VTDBus struct together with the vector
of device address space pointers indexed by devfn.
- The bus number is still used for lookup for selective SID based invalidate,
in which case the bus number is lazily resolved from the bus hash table and
cached in a separate index.

target-arm: Fix CPU breakpoint handling
A QEMU breakpoint match is not definitely an architectural breakpoint
match. If an exception is generated unconditionally during translation,
it is hardly possible to ignore it in the debug exception handler.
Generate a call to a helper to check CPU breakpoints and raise an
exception only if any breakpoint matches architecturally.

qemu-nbd: always compile in --aio=MODE option
The --aio=MODE option enables Linux AIO or Windows overlapped I/O.
The #ifdef CONFIG_LINUX_AIO was a layering violation that also prevented
Windows overlapped I/O from being used.
Now that raw-posix.c prints an error when Linux AIO has not been
compiled in, we can unconditionally compile the option into qemu-nbd.
After this patch qemu-nbd --aio=native works on Windows.

raw-posix: warn about BDRV_O_NATIVE_AIO if libaio is unavailable
raw-posix.c silently ignores BDRV_O_NATIVE_AIO if libaio is unavailable.
It is confusing when aio=native performance is identical to aio=threads
because the binary was accidentally built without libaio.
Print a deprecation warning if -drive aio=native is used with a binary
that does not support libaio. There are probably users using aio=native
who would be inconvenienced if QEMU suddenly refused to start their
guests. In the future this will become an error.

util - add automated ID generation utility
Multiple sub-systems in QEMU may find it useful to generate IDs
for objects that a user may reference via QMP or HMP. This patch
presents a standardized way to do it, so that automatic ID generation
follows the same rules.
This patch enforces the following rules when generating an ID:
1.) Guarantee no collisions with a user-specified ID
2.) Identify the sub-system the ID belongs to
3.) Guarantee of uniqueness
4.) Spoiling predictability, to avoid creating an assumption
of object ordering and parsing (i.e., we don't want users to think
they can guess the next ID based on prior behavior).
The scheme for this is as follows (no spaces):
# subsys D RR
Reserved char --| | | |
Subsystem String ----| | |
Unique number (64-bit) --| |
Two-digit random number ---|
For example, a generated node-name for the block sub-system may look
like this:
#block076
The caller of id_generate() is responsible for freeing the generated
node name string with g_free().

block: Add and use bdrv_replace_in_backing_chain()
This cleans up the mess we left behind in the mirror code after the
previous patch. Instead of using bdrv_swap(), just change pointers.
The interface change of the mirror job that callers must consider is
that after job completion, their local BDS pointers still point to the
same node now. qemu-img must change its code accordingly (which makes it
easier to understand); the other callers stays unchanged because after
completion they don't do anything with the BDS, but just with the job,
and the job is still owned by the source BDS.

blockjob: Store device name at job creation
Some block jobs change the block device graph on completion. This means
that the device that owns the job and originally was addressed with its
device name may no longer be what the corresponding BlockBackend points
to.
Previously, the effects of bdrv_swap() ensured that the job was (at
least partially) transferred to the target image. Events that contain
the device name could still use bdrv_get_device_name(job->bs) and get
the same result.
After removing bdrv_swap(), this won't work any more. Instead, save the
device name at job creation and use that copy for QMP events and
anything else identifying the job.

block: Implement bdrv_append() without bdrv_swap()
Remember all parent nodes and just change the pointers there instead of
swapping the contents of the BlockDriverState.
Handling of snapshot=on must be moved further down in bdrv_open()
because *pbs (which is the bs pointer in the BlockBackend) must already
be set before bdrv_append() is called. Otherwise bdrv_append() changes
the BB's pointer to the temporary snapshot, but bdrv_open() overwrites
it with the read-only original image.
We also need to be careful to update callers as the interface changes
(becomes less insane): Previously, the meaning of the two parameters was
inverted when bdrv_append() returns. Now any BDS pointers keep pointing
to the same node.

Since we cannot guarantee that abort() will produce a core dump, we
should use SIGKILL instead (that does not produce any) and update the

hw/arm/virt: smbios: inform guest of kvm
ARM/AArch64 KVM guests don't have any way to identify
themselves as KVM guests (x86 guests use a CPUID leaf). Now, we
could discuss all sorts of reasons why guests shouldn't need to
know that, but then there's always some case where it'd be
nice... Anyway, now that we have SMBIOS tables in ARM guests,
it's easy for the guest to know that it's a QEMU instance. This
patch takes that one step further, also identifying KVM, when
appropriate. Again, we could debate why generally nothing
should care whether it's of type QEMU or QEMU/KVM, but again,
sometimes it's nice to know...

target-arm: Break the TB after ISB to execute self-modified code correctly
If any store instruction writes the code inside the same TB
after this store insn, the execution of the TB must be stopped
to execute new code correctly.
As described in ARMv8 manual D3.4.6 self-modifying code must do an
IC invalidation to be valid, and an ISB after it. So it's enough to end
the TB after ISB instruction on the code translation.
Also this TB break is necessary to take any pending interrupts immediately
after an ISB (as required by ARMv8 ARM D1.14.4).

qapi: Track location that created an implicit type
A future patch will move some error checking from the parser
to the various QAPISchema*.check() methods, which run only
after parsing completes. It will thus be possible to create
a python instance representing an implicit QAPI type that
parses fine but will fail validation during check(). Since
all errors have to have an associated 'info' location, we
need a location to be associated with those implicit types.
The intuitive info to use is the location of the enclosing
entity that caused the creation of the implicit type.
Note that we do not anticipate builtin types being used in
an error message (as they are not part of the user's QAPI
input, the user can't cause a semantic error in their
behavior), so we exempt those types from requiring info, by
setting a flag to track the completion of _def_predefineds(),
and tracking that flag in _def_entity().
No change to the generated code.

qapi: Create simple union type member earlier
For simple unions, we were creating the implicit 'type' tag
member during the QAPISchemaObjectTypeVariants constructor.
This is different from every other implicit QAPISchemaEntity
object, which get created by QAPISchema methods. Hoist the
creation to the caller (renaming _make_tag_enum() to
_make_implicit_tag()), and pass the entity rather than the
string name, so that we have the nice property that no
entities are created as a side effect within a different
entity. A later patch will then have an easier time of
associating location info with each entity creation.

qapi: Lazy creation of array types
Commit ac88219a had several TODO markers about whether we needed
to automatically create the corresponding array type alongside
any other type. It turns out that most of the time, we don't!
There are a few exceptions: 1) We have a few situations where we
use an array type in internal code but do not expose that type
through QMP; fix it by declaring a dummy type that forces the
generator to see that we want to use the array type.
2) The builtin arrays (such as intList for QAPI ['int']) must
always be generated, because of the way our QAPI_TYPES_BUILTIN
compile guard works: we have situations (at the very least
tests/test-qmp-output-visitor.c) that include both top-level
"qapi-types.h" (via "error.h") and a secondary
"test-qapi-types.h". If we were to only emit the builtin types
when used locally, then the first .h file would not include all
types, but the second .h does not declare anything at all because
the first .h set QAPI_TYPES_BUILTIN, and we would end up with
compilation error due to things like unknown type 'int8List'.
Actually, we may need to revisit how we do type guards, and
change from a single QAPI_TYPES_BUILTIN over to a different
usage pattern that does one #ifdef per qapi type - right now,
the only types that are declared multiple times between two qapi
.json files for inclusion by a single .c file happen to be the
builtin arrays. But now that we have QAPI 'include' statements,
it is logical to assume that we will soon reach a point where
we want to reuse non-builtin types (yes, I'm thinking about what
it will take to add introspection to QGA, where we will want to
reuse the SchemaInfo type and friends). One #ifdef per type
will help ensure that generating the same qapi type into more
than one qapi-types.h won't cause collisions when both are
included in the same .c file; but we also have to solve how to
avoid creating duplicate qapi-types.c entry points. So that
is a problem left for another day.
Generated code for qapi-types and qapi-visit is drastically
reduced; less than a third of the arrays that were blindly
created were actually needed (a quick grep shows we dropped
from 219 to 69 *List types), and the .o files lost more than
30% of their bulk. [For best results, diff the generated
files with 'git diff --patience --no-index pre post'.]
Interestingly, the introspection output is unchanged - this is
because we already cull all types that are not indirectly
reachable from a command or event, so introspection was already
using only a subset of array types. The subset of types
introspected is now a much larger percentage of the overall set
of array types emitted in qapi-types.h (since the larger set
shrunk), but still not 100% (evidence that the array types
emitted for our new Dummy structs, and the new struct itself,
don't affect QMP).

qapi: Don't use info as witness of implicit object type
A future patch will enable error reporting from the various
QAPISchema*.check() methods. But to report an error related
to an implicit type, we'll need to associate a location with
the type (the same location as the top-level entity that is
causing the creation of the implicit type), and once we do
that, keying off of whether foo.info exists is no longer a
viable way to determine if foo is an implicit type.
Instead, add an is_implicit() method to QAPISchemaEntity, and use it.
It can be overridden later for ObjectType and EnumType, when implicit
instances of those classes gain info.

qapi: Prepare for errors during check()
The next few patches will start migrating error checking from
ad hoc parse methods into the QAPISchema*.check() methods. But
for an error message to display, we first have to fix the
overall 'try' to catch those errors. We also want to enable a
few more assertions, such as making sure every attempt to
raise a semantic error is passed a valid location info, or that
various preconditions hold.
The general approach for moving error checking will then be to
relax an assertion into an if that raises an exception if the
condition does not hold, and removing the counterpart ad hoc
check done during the parse phase.

qapi: Use predicate callback to determine visit filtering
Previously, qapi-types and qapi-visit filtered out implicit
objects during visit_object_type() by using 'info' (works since
implicit objects do not [yet] have associated info); meanwhile
qapi-introspect filtered out all schema types on the first pass
by returning a python type from visit_begin(), which was then
used at a distance in QAPISchema.visit() to do the filtering.
Rather than keeping these ad hoc approaches, add a new visitor
callback visit_needed() which returns False to skip a given
entity, and which defaults to True unless overridden. Use the
new mechanism to simplify all three filtering visitors.
No change to the generated code.

migration: fix deadlock
Release qemu global mutex before call synchronize_rcu().
synchronize_rcu() waiting for all readers to finish their critical
sections. There is at least one critical section in which we try
to get QGM (critical section is in address_space_rw() and
prepare_mmio_access() is trying to aquire QGM).
Both functions (migration_end() and migration_bitmap_extend())
are called from main thread which is holding QGM.
Thus there is a race condition that ends up with deadlock:
main thread working thread
Lock QGA |

| Open rcu reader's critical section
Migration cleanup bh |

synchronize_rcu() is |

README: fill out some useful quickstart information
The README file is usually the first thing consulted when a user
or developer obtains a copy of the QEMU source. The current QEMU
README is lacking immediately useful information and so not very
friendly for first time encounters. It either redirects users to
qemu-doc.html (which does not exist until they've actually
compiled QEMU), or the website (which assumes the user has
convenient internet access at time of reading).
This fills out the README file as simple quick-start guide on
the topics of building source, submitting patches, licensing
and how to contact the QEMU community. It does not intend to be
comprehensive, instead referring people to an appropriate web

qapi: Simplify gen_visit_fields() error handling
Since we have consolidated all generated code to use 'err' as
the name of the local variable for error detection, we can
simplify the decision on whether to skip error detection (useful
for deallocation paths) to be a boolean.

qapi: Share gen_visit_fields()
Consolidate the code between visit, command marshalling, and
event generation that iterates over the members of a struct.
It reduces code duplication in the generator, so that a future
patch can reduce the size of generated code while touching only
one instead of three locations.
There are no changes to the generated marshal code.
The visitor code becomes slightly more verbose, but remains
semantically equivalent, and is actually easier to read as
it follows a more common idiom:
| visit_optional(v, &(*obj)->has_device, "device", &err);
|- if (!err && (*obj)->has_device) {
|- visit_type_str(v, &(*obj)->device, "device", &err);
|- }
| if (err) {
| goto out;
| }
|+ if ((*obj)->has_device) {
|+ visit_type_str(v, &(*obj)->device, "device", &err);
|+ if (err) {
|+ goto out;
|+ }
|+ }
The event code becomes slightly more verbose, but this is
arguably a bug fix: although the visitors are not well
documented, use of an optional member should not be attempted
unless guarded by a prior call to visit_optional(). Works only
because the output qmp visitor has a no-op visit_optional():
|+ visit_optional(v, &has_offset, "offset", &err);
|+ if (err) {
|+ goto out;
|+ }
| if (has_offset) {
| visit_type_int(v, &offset, "offset", &err);

qapi-commands has a nice helper gen_err_check(), but did not

easier to reduce the lines of code used for generating error

to consolidate another common pattern among the generators.

but has no semantic difference.

qapi: Consistent generated code: minimize push_indent() usage
We had some pointless differences in the generated code for visit,
command marshalling, and events; unifying them makes it easier for
future patches to consolidate to common helper functions.
This is one patch of a series to clean up these differences.
This patch reduces the number of push_indent()/pop_indent() pairs
so that generated code is typically already at its natural output
indentation in the python files. It is easier to reason about
generated code if the reader does not have to track how much
spacing will be inserted alongside the code, and moreso when all
of the generators use the same patterns (qapi-type and qapi-event
were already using in-place indentation).
Arguably, the resulting python may be a bit harder to read with C
code at the same indentation as python; on the other hand, not
having to think about push_indent() is a win, and most decent
editors provide syntax highlighting that makes it easier to
visually distinguish python code from string literals that will
become C code.
There is no change to the generated output.

We had some pointless differences in the generated code for visit,

This is one patch of a series to clean up these differences.
This patch names the goto labels 'out' (not 'clean') and 'out_obj'
(not 'out_end'). Additionally, the generator was inconsistent on
whether labels had a leading space [our HACKING is silent; while
emacs 'gnu' style adds the space to avoid littering column 1].
For minimal churn, prefer no leading space; this also matches
the style that is more prevalent in current qemu.git.

structures.
Test flat-union-inline is updated to test only one feature
(anonymous branch dictionaries), which can be implemented

idea of an anonymous base dictionary).

qapi: Test use of 'number' within alternates
Add some testsuite exposure for use of a 'number' as part of
an alternate. The current state of the tree has a few bugs
exposed by this: our input parser depends on the ordering of
how the qapi schema declared the alternate, and the parser
does not accept integers for a 'number' in an alternate even
though it does for numbers outside of an alternate.
Mixing 'int' and 'number' in the same alternate is unusual,
since both are supplied by json-numbers, but there does not
seem to be a technical reason to forbid it given that our
json lexer distinguishes between json-numbers that can be
represented as an int vs. those that cannot.
Improve the existing test_visitor_in_alternate() to match the
style of the new test_visitor_in_alternate_number(), and to
ensure full coverage of all possible qtype parsing.

qapi: Add tests for empty unions
The documentation claims that alternates are useful for
allowing two or more types, although nothing enforces this.
Meanwhile, it is silent on whether empty unions are allowed.
In practice, the generated code will compile, in part because
we have a 'void *data' branch; but attempting to visit such a
type will cause an abort(). While there's no technical reason
that a degenerate union could not be made to work, it's harder
to justify the time spent in chasing known (the current
abort() during visit) and unknown corner cases, than it would
be to just outlaw them. A future patch will probably take the
approach of forbidding them; in the meantime, we can at least
add testsuite coverage to make it obvious where things stand.
In addition to adding tests to expose the problems, we also
need to adjust existing tests that are meant to test something
else, but which could fail for the wrong reason if we reject
degenerate alternates/unions.
Note that empty structs are explicitly supported (for example,
right now they are the only way to specify that one branch of a
flat union adds no additional members), and empty enums are
covered by the testsuite as working (even if they do not seem
to have much use).

qapi: Avoid assertion failure on union 'type' collision
The previous commit added two tests that triggered an assertion
failure. It's fairly straightforward to avoid the failure by
just outright forbidding the collision between a union's tag
values and its discriminator name (including the implicit name
'kind' supplied for simple unions [*]). Ultimately, we'd like
to move the collision detection into QAPISchema*.check(), but
for now it is easier just to enhance the existing checks.
[*] Of course, down the road, we have plans to rename the simple
union tag name to 'type' to match the QMP wire name, but the
idea of the collision will still be present even then.
Technically, we could avoid the collision by naming the C union
members representing each enum value as '_case_value' rather
than 'value'; but until we have an actual qapi client (and not
just our testsuite) that has a legitimate reason to match a
case label to the name of a QMP key and needs the name munging
to satisfy the compiler, it's easier to just reject the qapi
as invalid.

qapi: Test for various name collisions
Expose some weaknesses in the generator: we don't always forbid
the generation of structs that contain multiple members that map
to the same C or QMP name. This has already been marked FIXME in
qapi.py in commit d90675f, but having more tests will make sure
future patches produce desired behavior; and updating existing
patches to better document things doesn't hurt, either. Some of
these collisions are already caught in the old-style parser
checks, but ultimately we want all collisions to be caught in the
new-style QAPISchema*.check() methods.
This patch focuses on C struct members, and does not consider
collisions between commands and events (affecting C function
names), or even collisions between generated C type names with
user type names (for things like automatic FOOList struct
representing array types or FOOKind for an implicit enum).
There are two types of struct collisions we want to catch:
1) Collision between two keys in a JSON object. qapi.py prevents
that within a single struct (see test duplicate-key), but it is
possible to have collisions between a type's members and its
base type's members (existing tests struct-base-clash,
struct-base-clash-deep), and its flat union variant members
(renamed test flat-union-clash-member).
2) Collision between two members of the C struct that is generated
for a given QAPI type:
a) Multiple QAPI names map to the same C name (new test
args-name-clash)
b) A QAPI name maps to a C name that is used for another purpose
(new tests flat-union-clash-branch, struct-base-clash-base,
union-clash-data). We already fixed some such cases in commit
0f61af3e and 1e6c1616, but more remain.
c) Two C names generated for other purposes clash
(updated test alternate-clash, new test union-clash-branches,
union-clash-type, flat-union-clash-type)
Ultimately, if we need to have a flat union where a tag value
clashes with a base member name, we could change the generator to
name the union (using 'foo.u.value' rather than 'foo.value') or
otherwise munge the C name corresponding to tag values. But
unless such a need arises, it will probably be easier to just
forbid these collisions.
Some of these negative tests will be deleted later, and positive
tests added to qapi-schema-test.json in their place, when the
generator code is reworked to avoid particular code generation
collisions in class 2).
[Note that viewing this patch with git rename detection enabled
may see some confusion due to renaming some tests while adding
others, but where the content is similar enough that git picks
the wrong pre- and post-patch files to associate]

qapi: Sort qapi-schema tests
Recent changes to qapi have provided quite a bit of churn in
the makefile, because we are inconsistent on what order test
names appear in, and on whether to re-wrap the list of tests or
just add arbitrary line lengths. Writing the list in a sorted
fashion, one test per line, will make future patches easier
to see what tests are being added or removed by a patch.
Although it is tempting to use $(wildcard qapi-schema/*.json)
for a more compact listing, such an approach would risk picking
up leftover garbage .json files in the directory; so keeping
the list explicit is safer for ensuring reproducible tarballs
and test results.

qemu-sockets: fix conversion of ipv4/ipv6 JSON to QemuOpts
The QemuOpts-based code treats "option not set" and "option set
to false" the same way for the ipv4 and ipv6 options, because it
is meant to handle only the ",ipv4" and ",ipv6" substrings in
hand-crafted option parsers.
When converting InetSocketAddress to QemuOpts, however, it is
necessary to handle all three cases (not set, set to true, set
to false). Currently we are not handling all cases correctly.
The rules are:
* if none or both options are absent, leave things as is
* if the single present option is Y, the other should be N.
This can be implemented by leaving things as is, or by setting
the other option to N as done in this patch.
* if the single present option is N, the other should be Y.
This is handled by the "else if" branch of this patch.
This ensures that the ipv4 option has an effect on Windows,
where creating the socket with PF_UNSPEC makes an ipv6
socket. With this patch, ",ipv4" will result in a PF_INET
socket instead.

checkpatch: port fix from kernel "## is not a valid modifier"
checkpatch currently loops on fpu/softfloat.c
Turns out this is fixed in the Linux version of checkpatch.
So this is a port of Andy Whitcrofts fix from Linux,
Original commit was commit 89a883530fe7 ("checkpatch: ## is not a
valid modifier")
As suggested by Peter Maydell for the QEMU version we drop the last "|"
as there seems to be no need for that. (FWIW, the kernel discusion about
that dried out:

kvm-all: Align to qemu_real_host_page_size in kvm_set_phys_mem
As the comment in kvm_set_phys_mem() says, KVM works in page size chunks.
However it uses hardcoded TARGET_PAGE_SIZE which is 4K on most platforms
while actual host may use different page size, for example, PPC64 hosts
use 64K system pages.
This replaces static TARGET_PAGE_SIZE with run-time calculated
qemu_real_host_page_size.

exec.c: Collect AddressSpace related fields into a CPUAddressSpace struct
Gather up all the fields currently in CPUState which deal with the CPU's
AddressSpace into a separate CPUAddressSpace struct. This paves the way
for allowing the CPU to know about more than one AddressSpace.
The rearrangement also allows us to make the MemoryListener a directly
embedded object in the CPUAddressSpace (it could not be embedded in
CPUState because 'struct MemoryListener' isn't defined for the user-only
builds). This allows us to resolve the FIXME in tcg_commit() by going
directly from the MemoryListener to the CPUAddressSpace.
This patch extracts the actual update of the cached dispatch pointer
from cpu_reload_memory_map() (which is renamed accordingly to
cpu_reloading_memory_map() as it is only responsible for breaking
cpu-exec.c's RCU critical section now). This lets us keep the definition
of the CPUAddressSpace struct private to exec.c.

cpu-exec-common.c: Clarify comment about cpu_reload_memory_map()'s RCU operations
The reason for cpu_reload_memory_map()'s RCU operations is not
so much because the guest could make the critical section very
long, but that it could have a critical section within which
it made an arbitrary number of changes to the memory map and
thus accumulate an unbounded amount of memory data structures
awaiting reclamation. Clarify the comment to make this clearer.

exec.c: Don't call cpu_reload_memory_map() from cpu_exec_init()
Currently we call cpu_reload_memory_map() from cpu_exec_init(),
but this is not necessary:
* KVM doesn't use the data structures maintained by
cpu_reload_memory_map() (the TLB and cpu->memory_dispatch)
* for TCG, we will call this function via tcg_commit() either
as soon as tcg_cpu_address_space_init() registers the listener,
or when the first MemoryRegion is added to the AddressSpace
if the AS is empty when we register the listener
The unnecessary call is awkward for adding support for multiple
address spaces per CPU, so drop it.

virtio-blk: use blk_io_plug/unplug for Linux AIO batching
The raw-posix block driver implements Linux AIO batching so multiple
requests can be submitted with a single io_submit(2) system call.
Batching is currently only used by virtio-scsi and
virtio-blk-data-plane.
Enable batching for regular virtio-blk so the number of io_submit(2)
system calls is reduced for workloads with queue depth > 1.
In 4KB random read performance tests with queue depth 32, the CPU
utilization on the host is reduced by 9.4%. The fio job is as follows:
[global]
bs=4k
ioengine=libaio
iodepth=32
direct=1
sync=0
time_based=1
runtime=30
clocksource=gettimeofday
ramp_time=5

rw=randread
filename=/dev/vdb
size=4096M
write_bw_log=fio
write_iops_log=fio
write_lat_log=fio
log_avg_msec=1000
This benchmark was run on an raw image on LVM. The disk was an SSD
drive and -drive cache=none,aio=native was used.

netfilter: add a netbuffer filter
This filter is to buffer/release packets. Can be used when using
MicroCheckpointing or other Remus like VM FT solutions.
You can also use it to crudely simulate network delay. Doesn't
actually delay individual packets, but batches them together, which is
a delay of sorts.
Usage:
-netdev tap,id=bn0
-object filter-buffer,id=f0,netdev=bn0,queue=rx,interval=1000
NOTE:
Interval is in microseconds, it can't be omitted currently, and can't be 0.

Validation of l2 header length assumed minimal packet size as
eth_header + 2 * vlan_header regardless of the actual protocol.
This caused crash for valid non-IP packets shorter than 22 bytes, as
'tx_pkt->packet_type' hasn't been assigned for such packets, and
'vmxnet3_on_tx_done_update_stats()' expects it to be properly set.
Refine header length validation in 'vmxnet_tx_pkt_parse_headers'.
Check its return value during packet processing flow.
As a side effect, in case IPv4 and IPv6 header validation failure,
corrupt packets will be dropped.

Revert "qdev: Use qdev_get_device_class() for -device <type>,help"
This reverts commit 31bed5509dfcbdfc293154ce81086a4dbd7a80b6.
The reverted commit changed qdev_device_help() to reject abstract
devices and devices that have cannot_instantiate_with_device_add_yet
set, to fix crash bugs like -device x86_64-cpu,help.
Rejecting abstract devices makes sense: they're purely internal, and
the implementation of the help feature can't cope with them.
Rejecting non-pluggable devices makes less sense: even though you
can't use them with -device, the help may still be useful elsewhere,
for instance with -global. This is a regression: -device FOO,help
used to help even for FOO that aren't pluggable.
The previous two commits fixed the crash bug at a lower layer, so
reverting this one is now safe. Fixes the -device FOO,help
regression, except for the broken devices marked
cannot_even_create_with_object_new_yet. For those, the error message
is improved.
Example of a device where the regression is fixed:
$ qemu-system-x86_64 -device PIIX4_PM,help
PIIX4_PM.command_serr_enable=bool (on/off)
PIIX4_PM.multifunction=bool (on/off)
PIIX4_PM.rombar=uint32
PIIX4_PM.romfile=str
PIIX4_PM.addr=int32 (Slot and optional function number, example: 06.0 or 06)
PIIX4_PM.memory-hotplug-support=bool
PIIX4_PM.acpi-pci-hotplug-with-bridge-support=bool
PIIX4_PM.s4_val=uint8
PIIX4_PM.disable_s4=uint8
PIIX4_PM.disable_s3=uint8
PIIX4_PM.smb_io_base=uint32
Example of a device where it isn't fixed:
$ qemu-system-x86_64 -device host-x86_64-cpu,help
Can't list properties of device 'host-x86_64-cpu'
Both failed with "Parameter 'driver' expects pluggable device type"

qdev: Protect device-list-properties against broken devices
Several devices don't survive object_unref(object_new(T)): they crash
or hang during cleanup, or they leave dangling pointers behind.
This breaks at least device-list-properties, because
qmp_device_list_properties() needs to create a device to find its
properties. Broken in commit f4eb32b "qmp: show QOM properties in
device-list-properties", v2.1. Example reproducer:
$ qemu-system-aarch64 -nodefaults -display none -machine none -S -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 50, "minor": 4, "major": 2}, "package": ""}, "capabilities": []}}
{ "execute": "qmp_capabilities" }
{"return": {}}
{ "execute": "device-list-properties", "arguments": { "typename": "pxa2xx-pcmcia" } }
qemu-system-aarch64: /home/armbru/work/qemu/memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed.
Aborted (core dumped)
[Exit 134 (SIGABRT)]
Unfortunately, I can't fix the problems in these devices right now.
Instead, add DeviceClass member cannot_destroy_with_object_finalize_yet
to mark them:
* Hang during cleanup (didn't debug, so I can't say why):
"realview_pci", "versatile_pci".
* Dangling pointer in cpus: most CPUs, plus "allwinner-a10", "digic",
"fsl,imx25", "fsl,imx31", "xlnx,zynqmp", because they create such
CPUs
* Assert kvm_enabled(): "host-x86_64-cpu", host-i386-cpu",
"host-powerpc64-cpu", "host-embedded-powerpc-cpu",
"host-powerpc-cpu" (the powerpc ones can't currently reach the
assertion, because the CPUs are only registered when KVM is enabled,
but the assertion is arguably in the wrong place all the same)
Make qmp_device_list_properties() fail cleanly when the device is so
marked. This improves device-list-properties from "crashes, hangs or
leaves dangling pointers behind" to "fails". Not a complete fix, just
a better-than-nothing work-around. In the above reproducer,
device-list-properties now fails with "Can't list properties of device
'pxa2xx-pcmcia'".
This also protects -device FOO,help, which uses the same machinery
since commit ef52358 "qdev-monitor: include QOM properties in -device
FOO, help output", v2.2. Example reproducer:
$ qemu-system-aarch64 -machine none -device pxa2xx-pcmcia,help
Before:
qemu-system-aarch64: .../memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed.
After:
Can't list properties of device 'pxa2xx-pcmcia'

tests: Fix how qom-test is run
We want to run qom-test for every architecture, without having to
manually add it to every architecture's list of tests. Commit 3687d53
accomplished this by adding it to every architecture's list
automatically.
However, some architectures inherit their tests from others, like this:
check-qtest-x86_64-y = $(check-qtest-i386-y)
check-qtest-microblazeel-y = $(check-qtest-microblaze-y)
check-qtest-xtensaeb-y = $(check-qtest-xtensa-y)
For such architectures, we ended up running the (slow!) test twice.
Commit 2b8419c attempted to avoid this by adding the test only when
it's not already present. Works only as long as we consider adding
the test to the architectures on the left hand side *after* the ones
on the right hand side: x86_64 after i386, microblazeel after
microblaze, xtensaeb after xtensa.
Turns out we consider them in $(SYSEMU_TARGET_LIST) order. Defined as
SYSEMU_TARGET_LIST := $(subst -softmmu.mak,,$(notdir \
$(wildcard $(SRC_PATH)/default-configs/*-softmmu.mak)))
On my machine, this results in the oder xtensa, x86_64, microblazeel,
microblaze, i386. Consequently, qom-test runs twice for microblazeel
and x86_64.
Replace this complex and flawed machinery with a much simpler one: add
generic tests (currently just qom-test) to check-qtest-generic-y
instead of check-qtest-$(target)-y for every target, then run
$(check-qtest-generic-y) for every target.

This causes the region to outlive the object, because it attaches the

much worse for "instance_init" because it can cause dangling pointers

memory: allow destroying a non-empty MemoryRegion
This is legal; the MemoryRegion will simply unreference all the
existing subregions and possibly bring them down with it as well.
However, it requires a bit of care to avoid an infinite loop.
Finalizing a memory region cannot trigger an address space update,
but memory_region_del_subregion errs on the side of caution and
might trigger a spurious update: avoid that by resetting mr->enabled
first.

trace: remove malloc tracing
The malloc vtable is not supported anymore in glib, because it broke
when constructors called g_malloc. Remove tracing of g_malloc,
g_realloc and g_free calls.
Note that, for systemtap users, glib also provides tracepoints
glib.mem_alloc, glib.mem_free, glib.mem_realloc, glib.slice_alloc
and glib.slice_free.

linux-user: Remove type casts to union type
Casting to a union type is a gcc (and clang) extension. Other compilers
might not support it. This is not a problem today, but the type casts
can be removed easily. Smatch now no longer complains like before:
linux-user/syscall.c:3190:18: warning: cast to non-scalar

linux-user: Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T). Same Coccinelle semantic patch as in commit b45c03f.

.travis.yml: Run make check for all targets, not just some
ed173cb ".travis.yml: remove "make check" from main matrix" stopped running
make check for all the Travis build targets for various reasons. It
continued to run make check on one Travis build, which builds for a big
list of all (? nearly all) our supported softmmu targets.
Unfortunately, due to a spacing / quoting error it only actually builds for
the alpha, arm, aarch64 and cris targets. Specifically, the list of
targets is split over several lines. Even with YAML folding, this will
leave spaces in the list, meaning $TARGETS won't have the value we need.
I had a look at the YAML spec and I couldn't quickly see a way of splitting
the list so that it doesn't end up with spaces, so this patch fixes the
problem by putting the whole list on one huge line.

imx_serial: Generate interrupt on tx empty if enabled
Generate an interrupt if the tx buffer is empty and the tx empty interrupt

Linux commit 55c3cb1358e ("serial: imx: remove unneeded imx_transmit_buffer()
from imx_start_tx()"). Linux now waits for the tx empty interrupt before
starting to send data, causing transmit stalls until there is an interrupt

virtio-gpu: move iov free to virtio_gpu_cleanup_mapping_iov
For symmetry reasons: virtio_gpu_create_mapping_iov() allocates it so
virtio_gpu_cleanup_mapping_iov() should free it, otherwise it's easy to
miss a free() needed and leak memory.

tcg: Adjust CODE_GEN_AVG_BLOCK_SIZE
At present, the "average" guestimate of TB size is way too small, leading
to many unused entries in the pre-allocated TB array. For a guest with 1GB
ram, we're currently allocating 256MB for the array.
Survey arm, alpha, aarch64, ppc, sparc, i686, x86_64 guests running on
x86_64 and ppc64 hosts and select a new average. The size of the array
drops to 81MB with no more flushing than before.

tcg: Check for overflow via highwater mark
We currently pre-compute an worst case code size for any TB, which
works out to be 122kB. Since the average TB size is near 1kB, this
wastes quite a lot of storage.
Instead, check for overflow in between generating code for each opcode.
The overhead of the check isn't measurable and wastage is minimized.

This perhaps isn't ideal in terms of (ab)using the "pc" field

But it preserves existing logic, which will be good for bisection,
and it certainly does save storage space.

vfio: Allow hotplug of containers onto existing guest IOMMU mappings
At present the memory listener used by vfio to keep host IOMMU mappings
in sync with the guest memory image assumes that if a guest IOMMU
appears, then it has no existing mappings.
This may not be true if a VFIO device is hotplugged onto a guest bus
which didn't previously include a VFIO device, and which has existing
guest IOMMU mappings.
Therefore, use the memory_region_register_iommu_notifier_replay()
function in order to fix this case, replaying existing guest IOMMU
mappings, bringing the host IOMMU into sync with the guest IOMMU.

memory: Allow replay of IOMMU mapping notifications
When we have guest visible IOMMUs, we allow notifiers to be registered
which will be informed of all changes to IOMMU mappings. This is used by
vfio to keep the host IOMMU mappings in sync with guest IOMMU mappings.
However, unlike with a memory region listener, an iommu notifier won't be
told about any mappings which already exist in the (guest) IOMMU at the
time it is registered. This can cause problems if hotplugging a VFIO
device onto a guest bus which had existing guest IOMMU mappings, but didn't
previously have an VFIO devices (and hence no host IOMMU mappings).
This adds a memory_region_iommu_replay() function to handle this case. It
replays any existing mappings in an IOMMU memory region to a specified
notifier. Because the IOMMU memory region doesn't internally remember the
granularity of the guest IOMMU it has a small hack where the caller must
specify a granularity at which to replay mappings.
If there are finer mappings in the guest IOMMU these will be reported in
the iotlb structures passed to the notifier which it must handle (probably
causing it to flag an error). This isn't new - the VFIO iommu notifier
must already handle notifications about guest IOMMU mappings too short
for it to represent in the host IOMMU.

vfio: Check guest IOVA ranges against host IOMMU capabilities
The current vfio core code assumes that the host IOMMU is capable of
mapping any IOVA the guest wants to use to where we need. However, real
IOMMUs generally only support translating a certain range of IOVAs (the
"DMA window") not a full 64-bit address space.
The common x86 IOMMUs support a wide enough range that guests are very
unlikely to go beyond it in practice, however the IOMMU used on IBM Power
machines - in the default configuration - supports only a much more limited
IOVA range, usually 0..2GiB.
If the guest attempts to set up an IOVA range that the host IOMMU can't
map, qemu won't report an error until it actually attempts to map a bad
IOVA. If guest RAM is being mapped directly into the IOMMU (i.e. no guest
visible IOMMU) then this will show up very quickly. If there is a guest
visible IOMMU, however, the problem might not show up until much later when
the guest actually attempt to DMA with an IOVA the host can't handle.
This patch adds a test so that we will detect earlier if the guest is
attempting to use IOVA ranges that the host IOMMU won't be able to deal
with.
For now, we assume that "Type1" (x86) IOMMUs can support any IOVA, this is
incorrect, but no worse than what we have already. We can't do better for
now because the Type1 kernel interface doesn't tell us what IOVA range the
IOMMU actually supports.
For the Power "sPAPR TCE" IOMMU, however, we can retrieve the supported
IOVA range and validate guest IOVA ranges against it, and this patch does
so.

vfio: Generalize vfio_listener_region_add failure path
If a DMA mapping operation fails in vfio_listener_region_add() it
checks to see if we've already completed initial setup of the
container. If so it reports an error so the setup code can fail
gracefully, otherwise throws a hw_error().
There are other potential failure cases in vfio_listener_region_add()
which could benefit from the same logic, so move it to its own
fail: block. Later patches can use this to extend other failure cases
to fail as gracefully as possible under the circumstances.

vfio: Remove unneeded union from VFIOContainer
Currently the VFIOContainer iommu_data field contains a union with
different information for different host iommu types. However:
* It only actually contains information for the x86-like "Type1" iommu
* Because we have a common listener the Type1 fields are actually used
on all IOMMU types, including the SPAPR TCE type as well
In fact we now have a general structure for the listener which is unlikely
to ever need per-iommu-type information, so this patch removes the union.
In a similar way we can unify the setup of the vfio memory listener in
vfio_connect_container() that is currently split across a switch on iommu
type, but is effectively the same in both cases.
The iommu_data.release pointer was only needed as a cleanup function
which would handle potentially different data in the union. With the
union gone, it too can be removed.

hw/vfio/platform: irqfd setup sequence update
With current implementation, eventfd VFIO signaling is first set up and
then irqfd is setup, if supported and allowed.
This start sequence causes several issues with IRQ forwarding setup
which, if supported, is transparently attempted on irqfd setup:
IRQ forwarding setup is likely to fail if the IRQ is detected as under
injection into the guest (active at irqchip level or VFIO masked).
This currently always happens because the current sequence explicitly
VFIO-masks the IRQ before setting irqfd.
Even if that masking were removed, we couldn't prevent the case where
the IRQ is under injection into the guest.
So the simpler solution is to remove this 2-step startup and directly
attempt irqfd setup. This is what this patch does.
Also in case the eventfd setup fails, there is no reason to go farther:
let's abort.

Correctly re-init EFER state during INIT IPI
When doing a re-initialization of a CPU core, the default state is to _not_
have 64-bit long mode enabled. This means the LME (long mode enable) and LMA
(long mode active) bits in the EFER model-specific register should be cleared.
However, the EFER state is part of the CPU environment which is
preserved by do_cpu_init(), so if EFER.LME and EFER.LMA were set at the
time an INIT IPI was received, they will remain set after the init completes.
This is contrary to what the Intel architecture manual describes and what
happens on real hardware, and it leaves the CPU in a weird state that the
guest can't clear.
To fix this, the 'efer' member of the CPUX86State structure has been moved
to an area outside the region preserved by do_cpu_init(), so that it can
be properly re-initialized by x86_cpu_reset().

as part of SSE4.2, and LZCNT as part of BMI1, but Intel also uses AMD's
ABM flag to indicate support for both POPCNT and LZCNT. It has to be
added to Haswell and Broadwell because Haswell, by adding LZCNT, has
completed the ABM.

vl: Add another sanity check to smp_parse() function
The code in smp_parse already checks the topology information for
sockets * cores * threads < cpus and bails out with an error in
that case. However, it is still possible to supply a bad configuration
the other way round, e.g. with:
qemu-system-xxx -smp 4,sockets=1,cores=4,threads=2
QEMU then still starts the guest, with topology configuration that
is rather incomprehensible and likely not what the user wanted.
So let's add another check to refuse such wrong configurations.

block/raw-posix: Open file descriptor O_RDWR to work around glibc posix_fallocate emulation issue.
https://bugzilla.redhat.com/show_bug.cgi?id=1265196
The following command fails on an NFS mountpoint:
$ qemu-img create -f qcow2 -o preallocation=falloc disk.img 262144
Formatting 'disk.img', fmt=qcow2 size=262144 encryption=off cluster_size=65536 preallocation='falloc' lazy_refcounts=off
qemu-img: disk.img: Could not preallocate data for the new file: Bad file descriptor
The reason turns out to be because NFS doesn't support the
posix_fallocate call. glibc emulates it instead. However glibc's
emulation involves using the pread(2) syscall. The pread syscall
fails with EBADF if the file descriptor is opened without the read
open-flag (ie. open (..., O_WRONLY)).
I contacted glibc upstream about this, and their response is here:
https://bugzilla.redhat.com/show_bug.cgi?id=1265196#c9
There are two possible fixes: Use Linux fallocate directly, or (this
fix) work around the problem in qemu by opening the file with O_RDWR
instead of O_WRONLY.

s390x: set missing parent for hotplug and quiesce events
Existing code missed to set a parent for the quiesce and hotplug event.
While this didn't matter in practise, new introspection APIs basically now
do an object_unref(object_new(T)), which loops forever.
When trying to remove the event facility bus, the code tries to
unparent all childs on the bus, so they are properly deleted and therefore removed.
As object_unparent() on these child devices doesn't work, as there is no parent,
we loop forever.
Let's fix this by adding the event facility as a parent. Also switch from
object_initialize to object_new, so the only valid reference is in fact the
parent property. This makes it more obvious when the device (state) is actually
gone (and how the reference counting works).

Some gcc versions (e.g. Fedora 22 gcc 5.1.1) seem to use floating
point registers for spilling and filling of general purpose registers.
As the BIOS does not activate the AFP register setting of CR0 this can
cause data exception program checks.
Disallow floating point in the BIOS as a simple solution.

block: mirror - fix full sync mode when target does not support zero init
During mirror, if the target device does not support zero init, a
mirror may result in a corrupted image for sync="full" mode.
This is due to how the initial dirty bitmap is set up prior to copying
data - we did not mark sectors as dirty that are unallocated. This
means those unallocated sectors are skipped over on the target, and for
a device without zero init, invalid data may reside in those holes.
If both of the following conditions are true, then we will explicitly
mark all sectors as dirty:
1.) sync = "full"
2.) bdrv_has_zero_init(target) == false
If the target does support zero init, but a target image is passed in
with data already present (i.e. an "existing" image), it is assumed the
data present in the existing image is valid data for those sectors.

oslib: rework anonimous RAM allocation
At the moment we first allocate RAM, sometimes more than necessary for

Rework this to avoid the temporary allocation: reserve the

necessary range with MAP_FIXED.

virtio-net: correctly drop truncated packets
When packet is truncated during receiving, we drop the packets but
neither discard the descriptor nor add and signal used
descriptor. This will lead several issues:
- sg mappings are leaked
- rx will be stalled if a lots of packets were truncated
In order to be consistent with vhost, fix by discarding the descriptor
in this case.

Additionally, be more aggressive when deciding when to start throttling.
Previously we waited until four unproductive memory passes. Now we begin
throttling after only two unproductive memory passes. Four seemed quite
arbitrary and only waiting for two passes allows us to complete the migration
faster.

migration: Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T). Same Coccinelle semantic patch as in commit b45c03f.

linux-user: fix cmsg conversion in case of multiple headers
Currently, __target_cmsg_nxthdr compares a pointer derived from
target_cmsg against the msg_control field of target_msgh (through
subtraction). This failed for me when emulating i386 code under x86_64,
because pointers in the host address space and pointers in the guest
address space were not the same. This patch passes the initial value of
target_cmsg into __target_cmsg_nxthdr.
I found and fixed two more related bugs:
- __target_cmsg_nxthdr now returns the new cmsg pointer instead of the
old one.
- tgt_space (in host_to_target_cmsg) doesn't count "sizeof (struct
target_cmsghdr)" twice anymore.

linux-user: Add proper error messages for bad options
This patch adds better support for diagnosing option
parser errors. The previous implementation just printed
the usage text and exited when a bad option or argument
was found. This made it very difficult to determine why
the usage was being displayed and it was doubly confusing
for cases like '--help' (it wasn't clear that --help was
actually an error).

ui/cocoa.m: remove open dialog code
Removes the open dialog code that runs when no arguments are supplied with QEMU.
Not everyone needs a hard drive or cdrom to boot their target. A user might only
need to use their target's bios to do work. With that said, this patch removes
the unneeded open dialog code.

ui/cocoa.m: prevent stuck key situation
When the user puts QEMU in the background while holding
down a key, QEMU will not receive the keyup event when
the user lets go of the key. When the user goes back to
QEMU, QEMU will think the key is still down causing
stuck key symptoms. This patch fixes this problem by
releasing all down keys when QEMU goes into the
background.

sheepdog: refine discard support
This patch refines discard support of the sheepdog driver. The
existing discard mechanism was implemented on SD_OP_DISCARD_OBJ, which
was introduced before fine grained reference counting on newer
sheepdog. It doesn't care about relations of snapshots and clones and
discards objects unconditionally.
With this patch, the driver just updates an inode object for updating
reference. Removing the object is done in sheep process side.

sheepdog: use per AIOCB dirty indexes for non overlapping requests
In the commit 96b14ff85acf, requests for overlapping areas are
serialized. However, it cannot handle a case of non overlapping
requests. In such a case, min_dirty_data_idx and max_dirty_data_idx
can be overwritten by the requests and invalid inode update can
happen e.g. a case like create(1, 2) and create(3, 4) are issued in
parallel.
This patch lets SheepdogAIOCB have dirty data indexes instead of
BDRVSheepdogState for avoiding the above situation.
This patch also does trivial renaming for better description:

Backup: don't do copy-on-read in before_write_notifier
We will copy data in before_write_notifier to do backup.
It is a nested I/O request, so we cannot do copy-on-read.
The steps to reproduce it:
1. -drive copy-on-read=on,... // qemu option
2. drive_backup -f disk0 /path_to_backup.img // monitor command

block/nfs: cache allocated filesize for read-only files
If the file is readonly its not expected to grow so
save the blocking call to nfs_fstat_async and use
the value saved at connection time. Also important
the monitor (and thus the main loop) will not hang

linux-user: elfload: Provide default for elf_check_arch
For many arch's this macro is defined as the predicatable behaviour
of checking the argument for eqaulity against ELF_ARCH. Provide a
default define as such, so only archs with special handling (usually
allowing multiple EM values) need to provide a def.
Arches that do any of:
1: provide this def exactly the same way as the new default
(alpha, x86_64)
2: check against ELF_MACHINE while defining ELF_ARCH == ELF_MACHINE
(arm, aarch64)
3: check against EM_FOO directly while defining ELF_ARCH == EM_FOO
(unicore32, sparc32, ppc32, mips, openrisc, sh4, cris, m86k)
have their elf_check_arch removed as the default will provide the
correct behaviour.

Makefile: fix build when VPATH is outside GIT tree
Steve Ellcey / Leon Alrae reported that QEMU fails to build when
the VPATH directory is outside of the GIT tree, and the system
emulators & tools build is disabled. eg
cd ..
mkdir build
cd build
../qemu/configure --disable-system --disable-tools
make
(...)
make[1]: *** No rule to make target `../qom/object.o', needed by `qemu-aarch64'. Stop.
make: *** [subdir-aarch64-linux-user] Error 2
The problem is due to the fact that some sub directory deps
were listed against SOFTMMU_SUBDIR_RULES instead of SUBDIR_RULES,
so were only processed for system emulators, not user emalutors.

scsi-generic: let guests recognize readonly=on on passthrough devices
Passed-through SCSI devices can be opened with the readonly=on option.
When this happens, Linux filters away write commands so that the guest
cannot overwrite the contents of the device.
However, the guest does not know that the device is read-only, and
accepts writes. The writes only fail later when the page cache is
flushed.
This patch modifies scsi-generic to modify the MODE SENSE data and
set the read-only bit in the device-specific parameters, so that
the guest OS treats the disk as write protected.

oslib-win32: only provide localtime_r/gmtime_r if missing
The oslib-win32 file currently provides a localtime_r and
gmtime_r replacement unconditionally. Some versions of
Mingw-w64 would provide crude macros for localtime_r/gmtime_r
which QEMU takes care to disable. Latest versions of Mingw-w64
now provide actual functions for localtime_r/gmtime_r, but
with a twist that you have to include unistd.h or pthread.h
before including time.h. By luck some files in QEMU have
such an include order, resulting in compile errors:

This change adds a configure test to see if localtime_r
exits, and only enables the QEMU impl if missing. We also
re-arrange qemu-common.h try attempt to guarantee that all
source files get unistd.h before time.h and thus see the
localtime_r/gmtime_r defs.

qemu-thread: add a fast path to the Win32 QemuEvent
QemuEvents are used heavily by call_rcu. We do not want them to be slow,
but the current implementation does a kernel call on every invocation
of qemu_event_* and won't cut it.
So, wrap a Win32 manual-reset event with a fast userspace path. The
states and transitions are the same as for the futex and mutex/condvar
implementations, but the slow path is different of course. The idea
is to reset the Win32 event lazily, as part of a test-reset-test-wait
sequence. Such a sequence is, indeed, how QemuEvents are used by
RCU and other subsystems!
The patch includes a formal model of the algorithm.

vhost-user: add multiple queue support
This patch is initially based a patch from Nikolay Nikolaev.
This patch adds vhost-user multiple queue support, by creating a nc
and vhost_net pair for each queue.
Qemu exits if find that the backend can't support the number of requested
queues (by providing queues=# option). The max number is queried by a
new message, VHOST_USER_GET_QUEUE_NUM, and is sent only when protocol
feature VHOST_USER_PROTOCOL_F_MQ is present first.
The max queue check is done at vhost-user initiation stage. We initiate
one queue first, which, in the meantime, also gets the max_queues the
backend supports.
In older version, it was reported that some messages are sent more times
than necessary. Here we came an agreement with Michael that we could
categorize vhost user messages to 2 types: non-vring specific messages,
which should be sent only once, and vring specific messages, which should
be sent per queue.
Here I introduced a helper function vhost_user_one_time_request(), which
lists following messages as non-vring specific messages:
VHOST_USER_SET_OWNER
VHOST_USER_RESET_DEVICE
VHOST_USER_SET_MEM_TABLE
VHOST_USER_GET_QUEUE_NUM
For above messages, we simply ignore them when they are not sent the first
time.

virtio: ring sizes vs. reset
We allow guests to change the size of the virtqueue rings by supplying
a number of buffers that is different from the number of buffers the
device was initialized with. Current code has some problems, however,
since reset does not reset the ringsizes to the default values (as this
is not saved anywhere).
Let's extend the core code to keep track of the default ringsizes and
migrate them once the guest changed them for any of the virtqueues
for a device.

virtio-net: unbreak self announcement and guest offloads after migration
After commit 019a3edbb25f1571e876f8af1ce4c55412939e5d ("virtio: make
features 64bit wide"). Device's guest_features was actually set after
vdc->load(). This breaks the assumption that device specific load()
function can check guest_features. For virtio-net, self announcement
and guest offloads won't work after migration.
Fixing this by defer them to virtio_net_load() where guest_features
were guaranteed to be set. Other virtio devices looks fine.

the ACPI table generation code was wrongly using this total size as the

Make each device entry in the table half the total; this brings the
ACPI table into line with the code which generates the device tree

intc/gic: Extract some reusable vGIC code
Some functions previously used only by vGICv2 are useful also for vGICv3
implementation. Untie them from GICState and make accessible from within
other modules:
- kvm_arm_gic_set_irq()
- kvm_gic_supports_attr() - moved to common code and renamed to
kvm_device_check_attr()
- kvm_gic_access() - turned into GIC-independent kvm_device_access().
Data pointer changed to void * because some GICv3 registers are
64-bit wide
Some of these changes are not used right now, but they will be helpful for
implementing live migration.
Actually kvm_dist_get() and kvm_dist_put() could also be made reusable, but
they would require two extra parameters (s->dev_fd and s->num_cpu) as well as
lots of typecasts of 's' to DeviceState * and back to GICState *. This makes
the code very ugly so i decided to stop at this point. I tried also an
approach with making a base class for all possible GICs, but it would contain
only three variables (dev_fd, cpu_num and irq_num), and accessing them through
the rest of the code would be again tedious (either ugly casts or qemu-style
separate object pointer). So i disliked it too.

hw/intc: Implement GIC-500 base class
This class is to be used by both software and KVM implementations of GICv3
Currently it is mostly a placeholder, but in future it is supposed to hold
qemu's representation of GICv3 state, which is necessary for migration.
The interface of this class is fully compatible with GICv2 one. This is
done in order to simplify integration with existing code.

vfio/pci: Add emulated PCI IDs
Specifying an emulated PCI vendor/device ID can be useful for testing
various quirk paths, even though the behavior and functionality of
the device with bogus IDs is fully unsupportable. We need to use a
uint32_t for the vendor/device IDs, even though the registers
themselves are only 16-bit in order to be able to determine whether
the value is valid and user set.
The same support is added for subsystem vendor/device ID, though these
have the possibility of being useful and supported for more than a
testing tool. An emulated platform might want to impose their own
subsystem IDs or at least hide the physical subsystem ID. Windows
guests will often reinstall drivers due to a change in subsystem IDs,
something that VM users may want to avoid. Of course careful
attention would be required to ensure that guest drivers do not rely
on the subsystem ID as a basis for device driver quirks.
All of these options are added using the standard experimental option
prefix and should not be considered stable.

vfio/pci: Config window quirks
Config windows make use of an address register and a data register.
In VGA cards, these are often used to provide real mode code in the
BIOS an easy way to access MMIO registers since the window often
resides in an I/O port register. When the MMIO register has a mirror
of PCI config space, we need to trap those accesses and redirect them
to emulated config space.
The previous version of this functionality made use of a single
MemoryRegion and single match address. This version uses separate
MemoryRegions for each of the address and data registers and allows
for multiple match addresses. This is useful for Nvidia cards which
have two ranges which index into PCI config space.
The previous implementation is left for the follow-on patch for a more
reviewable diff.

vfio/pci: Foundation for new quirk structure
VFIOQuirk hosts a single memory region and a fixed set of data fields
that try to handle all the quirk cases, but end up making those that
don't exactly match really confusing. This patch introduces a struct
intended to provide more flexibility and simpler code. VFIOQuirk is
stripped to its basics, an opaque data pointer for quirk specific
data and a pointer to an array of MemoryRegions with a counter. This
still allows us to have common teardown routines, but adds much
greater flexibility to support multiple memory regions and quirk
specific data structures that are easier to maintain. The existing
VFIOQuirk is transformed into VFIOLegacyQuirk, which further patches
will eliminate entirely.

vfio/pci: Cleanup ROM blacklist quirk
Create a vendor:device ID helper that we'll also use as we rework the
rest of the quirks. Re-reading the config entries, even if we get
more blacklist entries, is trivial overhead and only incurred during
device setup. There's no need to typedef the blacklist structure,
it's a static private data type used once. The elements get bumped
up to uint32_t to avoid future maintenance issues if PCI_ANY_ID gets
used for a blacklist entry (avoiding an actual hardware match). Our
test loop is also crying out to be simplified as a for loop.

ppc/spapr: Implement H_RANDOM hypercall in QEMU
The PAPR interface defines a hypercall to pass high-quality
hardware generated random numbers to guests. Recent kernels can
already provide this hypercall to the guest if the right hardware
random number generator is available. But in case the user wants
to use another source like EGD, or QEMU is running with an older
kernel, we should also have this call in QEMU, so that guests that
do not support virtio-rng yet can get good random numbers, too.
This patch now adds a new pseudo-device to QEMU that either
directly provides this hypercall to the guest or is able to
enable the in-kernel hypercall if available. The in-kernel
hypercall can be enabled with the use-kvm property, e.g.:
qemu-system-ppc64 -device spapr-rng,use-kvm=true
For handling the hypercall in QEMU instead, a "RngBackend" is
required since the hypercall should provide "good" random data
instead of pseudo-random (like from a "simple" library function
like rand() or g_random_int()). Since there are multiple RngBackends
available, the user must select an appropriate back-end via the
"rng" property of the device, e.g.:
qemu-system-ppc64 -object rng-random,filename=/dev/hwrng,id=gid0 \
-device spapr-rng,rng=gid0 ...
See http://wiki.qemu-project.org/Features-Done/VirtIORNG for
other example of specifying RngBackends.

ppc/spapr: Fix buffer overflow in spapr_populate_drconf_memory()
The buffer that is allocated in spapr_populate_drconf_memory()
is used for setting both, the "ibm,dynamic-memory" and the
"ibm,associativity-lookup-arrays" property. However, only the
size of the first one is taken into account when allocating the
memory. So if the length of the second property is larger than
the length of the first one, we run into a buffer overflow here!
Fix it by taking the length of the second property into account,
too.

spapr: Fix default NUMA node allocation for threads
At present, if guest numa nodes are requested, but the cpus in each node
are not specified, spapr just uses the default behaviour or assigning each
vcpu round-robin to nodes.
If smp_threads != 1, that will assign adjacent threads in a core to
different NUMA nodes. As well as being just weird, that's a configuration
that can't be represented in the device tree we give to the guest, which
means the guest and qemu end up with different ideas of the NUMA topology.
This patch implements mc->cpu_index_to_socket_id in the spapr code to
make sure vcpus get assigned to nodes only at the socket granularity.

rtas log buffer thus resulting in loss of memory hotplug events. Switch

spapr: Don't allow memory hotplug to memory less nodes
Currently PowerPC kernel doesn't allow hot-adding memory to memory-less
node, but instead will silently add the memory to the first node that has
some memory. This causes two unexpected behaviours for the user.
- Memory gets hotplugged to a different node than what the user specified.
- Since pc-dimm subsystem in QEMU still thinks that memory belongs to
memory-less node, a reboot will set things accordingly and the previously
hotplugged memory now ends in the right node. This appears as if some
memory moved from one node to another.
So until kernel starts supporting memory hotplug to memory-less
nodes, just prevent such attempts upfront in QEMU.

This changes the way memory node configuration is done. Currently all

for RMA is built upfront. Guest kernel boots with just that and rest of
the memory nodes (via memory@XXX or ibm,dynamic-reconfiguration-memory)
are built when guest does ibm,client-architecture-support call.

spapr: Use QEMU limit for maximum CPUs number
sPAPR uses hard coded limit of maximum 255 supported CPUs which is
exactly the same as QEMU-wide limit which is MAX_CPUMASK_BITS and also
defined as 255.
This makes use of a global CPU number limit for the "pseries" machine.
In order to anticipate future increase of the MAX_CPUMASK_BITS
(or to help debugging large systems), this also bumps the FDT_MAX_SIZE
limit from 256K to 1M assuming that 1 CPU core needs roughly 512 bytes
in the device tree so the new limit can cover up to 2048 CPU cores.

spapr: Don't use QOM [*] syntax for DR connectors.
The dynamic reconfiguration (hotplug) code for the pseries machine type
uses a "DR connector" QOM object for each resource it will be possible
to hotplug. Each of these is added to its owner using
object_property_add_child(owner, "dr-connector[*], ...);
That works ok, mostly, but it means that the property indices are
arbitrary, depending on the order in which the connectors are constructed.
That might line up to something useful, but it doesn't have to.
It will get worse once we add hotplug RAM support. That will add a DR
connector object for every 256MB of potential memory. So if maxmem=2T,
for example, there are 8192 objects under the same parent.
The QOM interfaces aren't really designed for this. In particular
object_property_add() with [*] has O(n^2) time complexity (in the number of
existing children): first it has a linear search through array indices to
find a free slot, each of which is attempted to a recursive call to
object_property_add() with a specific [N]. Those calls are O(n) because
there's a linear search through all properties to check for duplicates.
By using a meaningful index value, which we already know is unique we can
avoid the [*] special behaviour. That lets us reduce the total time for
creating the DR objects from O(n^3) to O(n^2).
O(n^2) is still kind of crappy, but it's enough to reduce the startup time
of qemu (with in-progress memory hotplug support) with maxmem=2T from ~20
minutes to ~4 seconds.

spapr_drc: use RTAS return codes for methods called by RTAS
Certain methods in sPAPRDRConnector objects are only ever called by
RTAS and in many cases are responsible for the logic that determines
the RTAS return codes.
Rather than having a level of indirection requiring RTAS code to
re-interpret return values from such methods to determine the
appropriate return code, just pass them through directly.
This requires changing method return types to uint32_t to match the
type of values currently passed to RTAS helpers.
In the case of read accesses like drc->entity_sense() where we weren't
previously reporting any errors, just the read value, we modify the
function to return RTAS return code, and pass the read value back via
reference.

spapr_drc: don't allow 'empty' DRCs to be unisolated or allocated
Logical resources start with allocation-state:UNUSABLE /
isolation-state:ISOLATED. During hotplug, guests will transition
them to allocation-state:USABLE, and then to
isolation-state:UNISOLATED.
For cases where we cannot transition to allocation-state:USABLE,
in this case due to no device/resource being association with
the logical DRC, we should return an error -3.
For physical DRCs, we default to allocation-state:USABLE and stay
there, so in this case we should report an error -3 when the guest
attempts to make the isolation-state:ISOLATED transition for a DRC
with no device associated.
These are as documented in PAPR 2.7, 13.5.3.4.
We also ensure allocation-state:USABLE when the guest attempts
transition to isolation-state:UNISOLATED to deal with misbehaving
guests attempting to bring online an unallocated logical resource.
This is as documented in PAPR 2.7, 13.7.
Currently we implement no such error logic. Fix this by handling
these error cases as PAPR defines.

spapr_pci: fix device tree props for MSI/MSI-X
PAPR requires ibm,req#msi and ibm,req#msi-x to be present in the
device node to define the number of msi/msi-x interrupts the device
supports, respectively.
Currently we have ibm,req#msi-x hardcoded to a non-sensical constant
that happens to be 2, and are missing ibm,req#msi entirely. The result
of that is that msi-x capable devices get limited to 2 msi-x
interrupts (which can impact performance), and msi-only devices likely
wouldn't work at all. Additionally, if devices expect a minimum that
exceeds 2, the guest driver may fail to load entirely.
SLOF still owns the generation of these properties at boot-time
(although other device properties have since been offloaded to QEMU),
but for hotplugged devices we rely on the values generated by QEMU
and thus hit the limitations above.
Fix this by generating these properties in QEMU as expected by guests.
In the future it may make sense to modify SLOF to pass through these
values directly as we do with other props since we're duplicating SLOF
code.

pseries: Fix incorrect calculation of threads per socket for chip-id
The device tree presented to pseries machine type guests includes an
ibm,chip-id property which gives essentially the socket number of each
vcpu core (individual vcpu threads don't get a node in the device
tree).
To calculate this, it uses a vcpus_per_socket variable computed as
(smp_cpus / #sockets). This is correct for the usual case where
smp_cpus == smp_threads * smp_cores * #sockets.
However, you can start QEMU with the number of cores and threads
mismatching the total number of vcpus (whether that _should_ be
permitted is a topic for another day). It's a bit hard to say what
the "real" number of vcpus per socket here is, but for most purposes
(smp_threads * smp_cores) will more meaningfully match how QEMU
behaves with respect to socket boundaries.

pseries: define coldplugged devices as "configured"
When a device is hotplugged, attach() sets "configured" to
false, waiting an action from the OS to configure it and then
to call ibm,configure-connector. On ibm,configure-connector,
the hypervisor sets "configured" to true.
In case of coldplugged device, attach() sets "configured" to
false, but firmware and OS never call the ibm,configure-connector
in this case, so it remains set to false.
It could be harmless, but when we unplug a device, hypervisor
waits the device becomes configured because for it, a not configured
device is a device being configured, so it waits the end of configuration
to unplug it... and it never happens, so it is never unplugged.
This patch set by default coldplugged device to "configured=true",
hotplugged device to "configured=false".

ppc/spapr: Use qemu_log_mask() for hcall_dprintf()
To see the output of the hcall_dprintf statements, you currently have
to enable the DEBUG_SPAPR_HCALLS macro in include/hw/ppc/spapr.h.
This is ugly because a) not every user who wants to debug guest
problems can or wants to recompile QEMU to be able to see such issues,
and b) since this macro is disabled by default, the code in the
hcall_dprintf() brackets tends to bitrot until somebody temporarily
enables that macro again.
Since the hcall_dprintf statements except one indicate guest
problems, let's always use qemu_log_mask(LOG_GUEST_ERROR, ...) for
this macro instead. One spot indicated an unimplemented host feature,
so this is changed into qemu_log_mask(LOG_UNIMP, ...) instead. Now
it's possible to see all those messages by simply adding the CLI
parameter "-d guest_errors,unimp", without the need to re-compile
the binary.

The DRC_INDEX_ID_MASK macro does a left shift on ~0, which is a signed

This fixes it by calculating the same mask without using ~0 (I think the
new method is a more common idiom for generating masks anyway). For good
measure I also use 1ULL to force the expression's type to unsigned long
long, which should be good for assigning to anything we're going to want

monitor: allow device_del to accept QOM paths
Currently device_del requires that the client provide the
device short ID. device_add allows devices to be created
without giving an ID, at which point there is no way to
delete them with device_del. The QOM object path, however,
provides an alternative way to identify the devices.
Allowing device_del to accept an object path ensures all
devices are deletable regardless of whether they have an
ID.

Devices are required to be marked as hotpluggable
otherwise an error is raised

qapi: New QMP command query-qmp-schema for QMP introspection
qapi/introspect.json defines the introspection schema. It's designed
for QMP introspection, but should do for similar uses, such as QGA.
The introspection schema does not reflect all the rules and
restrictions that apply to QAPI schemata. A valid QAPI schema has an
introspection value conforming to the introspection schema, but the
converse is not true.
Introspection lowers away a number of schema details, and makes
implicit things explicit:
* The built-in types are declared with their JSON type.
All integer types are mapped to 'int', because how many bits we use
internally is an implementation detail. It could be pressed into
external interface service as very approximate range information,
but that's a bad idea. If we need range information, we better do
it properly.
* Implicit type definitions are made explicit, and given
auto-generated names:
- Array types, named by appending "List" to the name of their
element type, like in generated C.
- The enumeration types implicitly defined by simple union types,
named by appending "Kind" to the name of their simple union type,
like in generated C.
- Types that don't occur in generated C. Their names start with ':'
so they don't clash with the user's names.
* All type references are by name.
* The struct and union types are generalized into an object type.
* Base types are flattened.
* Commands take a single argument and return a single result.
Dictionary argument or list result is an implicit type definition.
The empty object type is used when a command takes no arguments or
produces no results.
The argument is always of object type, but the introspection schema
doesn't reflect that.
The 'gen': false directive is omitted as implementation detail.
The 'success-response' directive is omitted as well for now, even
though it's not an implementation detail, because it's not used by
QMP.
* Events carry a single data value.
Implicit type definition and empty object type use, just like for
commands.
The value is of object type, but the introspection schema doesn't
reflect that.
* Types not used by commands or events are omitted.
Indirect use counts as use.
* Optional members have a default, which can only be null right now
Instead of a mandatory "optional" flag, we have an optional default.
No default means mandatory, default null means optional without
default value. Non-null is available for optional with default
(possible future extension).
* Clients should *not* look up types by name, because type names are
not ABI. Look up the command or event you're interested in, then
follow the references.
TODO Should we hide the type names to eliminate the temptation?
New generator scripts/qapi-introspect.py computes an introspection
value for its input, and generates a C variable holding it.
It can generate awfully long lines. Marked TODO.
A new test-qmp-input-visitor test case feeds its result for both
tests/qapi-schema/qapi-schema-test.json and qapi-schema.json to a
QmpInputVisitor to verify it actually conforms to the schema.
New QMP command query-qmp-schema takes its return value from that
variable. Its reply is some 85KiBytes for me right now.
If this turns out to be too much, we have a couple of options:
* We can use shorter names in the JSON. Not the QMP style.
* Optionally return the sub-schema for commands and events given as
arguments.
Right now qmp_query_schema() sends the string literal computed by
qmp-introspect.py. To compute sub-schema at run time, we'd have to
duplicate parts of qapi-introspect.py in C. Unattractive.
* Let clients cache the output of query-qmp-schema.
It changes only on QEMU upgrades, i.e. rarely. Provide a command
query-qmp-schema-hash. Clients can have a cache indexed by hash,
and re-query the schema only when they don't have it cached. Even
simpler: put the hash in the QMP greeting.

qapi: Make output visitor return qnull() instead of NULL
Before commit 1d10b44, it crashed. Since then, it returns NULL, with
a FIXME comment. The FIXME is valid: code that assumes QObject *
can't be null exists. I'm not aware of a way to feed this problematic
return value to code that actually chokes on null in the current code,
but the next few commits will create one, failing "make check".
Commit 481b002 solved a very similar problem by introducing a special
null QObject. Using this special null QObject is clearly the right
way to resolve this FIXME, so do that, and update the test
accordingly.
However, the patch isn't quite right: it messes up the reference
counting. After about SIZE_MAX visits, the reference counter
overflows, failing the assertion in qnull_destroy_obj(). Because
that's many orders of magnitude more visits of nulls than we expect,
we take this patch despite its flaws, to get the QMP introspection
stuff in without further delay. We'll want to fix it for real before
the release.

qapi-commands: Rearrange code
Rename gen_marshal_input() to gen_marshal(), because the generated
function marshals both arguments and results.
Rename gen_visitor_input_containers_decl() to gen_marshal_vars(), and
move the other variable declarations there, too.
Rename gen_visitor_input_block() to gen_marshal_input_visit(), and
rearrange its code slightly.
Rename gen_marshal_input_decl() to gen_marshal_proto(), because the
result isn't a full declaration, unlike gen_command_decl()'s.
New gen_marshal_decl() actually returns a full declaration.

qapi-visit: Convert to QAPISchemaVisitor, fixing bugs

commit merely added them to the struct). Same test case.
Patch's effect on visit_type_UserDefFlatUnion():
static void visit_type_UserDefFlatUnion_fields(Visitor *m, UserDefFlatUnion **obj, Error **errp)
{
Error *err = NULL;
+ visit_type_int(m, &(*obj)->integer, "integer", &err);

+ goto out;

visit_type_str(m, &(*obj)->string, "string", &err);

Test cases updated for the bug fix.
Fixes alternates to generate a visitor for their implicit enumeration
type. None of them are currently used, obviously. Example:
block-core.json's BlockdevRef now generates
visit_type_BlockdevRefKind().
Code is generated in a different order now, and therefore has got a
few new forward declarations. Doesn't matter.

qapi-types: Convert to QAPISchemaVisitor, fixing flat unions
Fixes flat unions to get the base's base members. Test case is from
commit 2fc0043, in qapi-schema-test.json:
{ 'union': 'UserDefFlatUnion',
'base': 'UserDefUnionBase',
'discriminator': 'enum1',
'data': { 'value1' : 'UserDefA',
'value2' : 'UserDefB',
'value3' : 'UserDefB' } }
{ 'struct': 'UserDefUnionBase',
'base': 'UserDefZero',
'data': { 'string': 'str', 'enum1': 'EnumOne' } }
{ 'struct': 'UserDefZero',
'data': { 'integer': 'int' } }
Patch's effect on UserDefFlatUnion:
struct UserDefFlatUnion {
/* Members inherited from UserDefUnionBase: */
+ int64_t integer;
char *string;
EnumOne enum1;
/* Own members: */
union { /* union tag is @enum1 */
void *data;
UserDefA *value1;
UserDefB *value2;
UserDefB *value3;
};
};
Flat union visitors remain broken. They'll be fixed next.
Code is generated in a different order now, but that doesn't matter.
The two guards QAPI_TYPES_BUILTIN_STRUCT_DECL and
QAPI_TYPES_BUILTIN_CLEANUP_DECL are replaced by just
QAPI_TYPES_BUILTIN.
Two ugly special cases for simple unions now stand out like sore
thumbs:
1. The type tag is named 'type' everywhere, except in generated C,
where it's 'kind'.
2. QAPISchema lowers simple unions to semantically equivalent flat
unions. However, the C generated for a simple unions differs from
the C generated for its equivalent flat union, and we therefore
need special code to preserve that pointless difference for now.
Mark both TODO.

qapi: New QAPISchema intermediate reperesentation
The QAPI code generators work with a syntax tree (nested dictionaries)
plus a few symbol tables (also dictionaries) on the side.
They have clearly outgrown these simple data structures. There's lots
of rummaging around in dictionaries, and information is recomputed on
the fly. For the work I'm going to do, I want more clearly defined
and more convenient interfaces.
Going forward, I also want less coupling between the back-ends and the
syntax tree, to make messing with the syntax easier.
Create a bunch of classes to represent QAPI schemata.
Have the QAPISchema initializer call the parser, then walk the syntax
tree to create the new internal representation, and finally perform
semantic analysis.
Shortcut: the semantic analysis still relies on existing check_exprs()
to do the actual semantic checking. All this code needs to move into
the classes. Mark as TODO.
Simple unions are lowered to flat unions. Flat unions and structs are
represented as a more general object type.
Catching name collisions in generated code would be nice. Mark as
TODO.
We generate array types eagerly, even though most of them aren't used.
Mark as TODO.
Nothing uses the new intermediate representation just yet, thus no
change to generated files.

tcg/mips: Fix clobbering of qemu_ld inputs
The MIPS TCG backend implements qemu_ld with 64-bit targets using the v0
register (base) as a temporary to load the upper half of the QEMU TLB
comparator (see line 5 below), however this happens before the input
address is used (line 8 to mask off the low bits for the TLB
comparison, and line 12 to add the host-guest offset). If the input
address (addrl) also happens to have been placed in v0 (as in the second
column below), it gets clobbered before it is used.
addrl in t2 addrl in v0

12 addu v0,a0,t2 addu v0,a0,v0 use addrl, addend
13 lw t0,0(v0) lw t0,0(v0)
Fix by using TCG_TMP0 (at) as the temporary instead of v0 (base),
pushing the load on line 5 forward into the delay slot of the low
comparison (line 10). The early load of the addend on line 7 also needs
pushing even further for 64-bit targets, or it will clobber a0 before
we're done with it. The output for 32-bit targets is unaffected.

qdev: Do not use slow [*] expansion for GPIO creation
Expansion of [*] suffix is very slow because index expansion is done using
trial and error strategy, starting every time from zero and retrying with
the next index until insertion succeeds. With large number of already added
properties this process takes huge amount of time (O(n^2) complexity).
Some architectures (like ARM) use very large amount of IRQ pins in interrupt
controller models. This flaw makes machine startup extremely slow
(~20 seconds for ARM64 with 32 CPUs). This patch decreases this time down to
~10 seconds.
Also in qdev_init_gpio_out_named() memset() is now called only once for the
whole array instead of per-cell cleaning

qom: Fix invalid error check in property_get_str()
When a function returns a null pointer on error and only on error, you
can do

}
instead of the more cumbersome
Error *err = NULL;
if (!foo(foos, &err)) {
error_propagate(errp, err);

}
A StringProperty's getter, however, may return null on success! We
then fail to call visit_type_str().

The initial register device-to-host FIS no longer needs to specially

(1) Signatures are decomposed into their four component registers and
set upon (AHCI) port reset.
(2) the signature cache register is no longer set manually per-each
device type, but instead just once during ahci_init_d2h.

atapi: abort transfers with 0 byte limits
We're supposed to abort on transfers like this, unless we fill
Word 125 of our IDENTIFY data with a default transfer size, which
we don't currently do.
This is an ATA error, not a SCSI/ATAPI one.
See ATA8-ACS3 sections 7.17.6.49 or 7.21.5.
If we don't do this, QEMU will loop forever trying to transfer
zero bytes, which isn't particularly useful.

ide: fix ATAPI command permissions
We're a little too lenient with what we'll let an ATAPI drive handle.
Clamp down on the IDE command execution table to remove CD_OK permissions
from commands that are not and have never been ATAPI commands.
For ATAPI command validity, please see:
- ATA4 Section 6.5 ("PACKET Command feature set")
- ATA8/ACS Section 4.3 ("The PACKET feature set")
- ACS3 Section 4.3 ("The PACKET feature set")
ACS3 has a historical command validity table in Table B.4
("Historical Command Assignments") that can be referenced to find when
a command was introduced, deprecated, obsoleted, etc.
The only reference for ATAPI command validity is by checking that
version's PACKET feature set section.
ATAPI was introduced by T13 into ATA4, all commands retired prior to ATA4
therefore are assumed to have never been ATAPI commands.
Mandatory commands, as listed in ATA8-ACS3, are:
- DEVICE RESET
- EXECUTE DEVICE DIAGNOSTIC
- IDENTIFY DEVICE
- IDENTIFY PACKET DEVICE
- NOP
- PACKET
- READ SECTOR(S)
- SET FEATURES
Optional commands as listed in ATA8-ACS3, are:
- FLUSH CACHE
- READ LOG DMA EXT
- READ LOG EXT
- WRITE LOG DMA EXT
- WRITE LOG EXT
All other commands are illegal to send to an ATAPI device and should
be rejected by the device.
CD_OK removal justifications:
0x06 WIN_DSM Defined in ACS2. Not valid for ATAPI.
0x21 WIN_READ_ONCE Retired in ATA5. Not ATAPI in ATA4.
0x94 WIN_STANDBYNOW2 Retired in ATA4. Did not coexist with ATAPI.
0x95 WIN_IDLEIMMEDIATE2 Retired in ATA4. Did not coexist with ATAPI.

memory: Fix bad error handling in memory_region_init_ram_ptr()
Commit ef701d7 screwed up handling of out-of-memory conditions.
Before the commit, we report the error and exit(1), in one place. The
commit lifts the error handling up the call chain some, to three
places. Fine. Except it uses &error_abort in these places, changing
the behavior from exit(1) to abort(), and thus undoing the work of
commit 3922825 "exec: Don't abort when we can't allocate guest
memory".
The previous two commits fixed one of the three places, another one
was fixed in commit 33e0eb5. This commit fixes the third one.

Fix bad error handling after memory_region_init_ram()
Symptom:
$ qemu-system-x86_64 -m 10000000
Unexpected error in ram_block_add() at /work/armbru/qemu/exec.c:1456:
upstream-qemu: cannot set up guest memory 'pc.ram': Cannot allocate memory
Aborted (core dumped)
Root cause: commit ef701d7 screwed up handling of out-of-memory
conditions. Before the commit, we report the error and exit(1), in
one place, ram_block_add(). The commit lifts the error handling up
the call chain some, to three places. Fine. Except it uses
&error_abort in these places, changing the behavior from exit(1) to
abort(), and thus undoing the work of commit 3922825 "exec: Don't
abort when we can't allocate guest memory".
The three places are:
* memory_region_init_ram()
Commit 4994653 (right after commit ef701d7) lifted the error
handling further, through memory_region_init_ram(), multiplying the
incorrect use of &error_abort. Later on, imitation of existing
(bad) code may have created more.
* memory_region_init_ram_ptr()
The &error_abort is still there.
* memory_region_init_rom_device()
Doesn't need fixing, because commit 33e0eb5 (soon after commit
ef701d7) lifted the error handling further, and in the process
changed it from &error_abort to passing it up the call chain.
Correct, because the callers are realize() methods.
Fix the error handling after memory_region_init_ram() with a
Coccinelle semantic patch:
@r@
expression mr, owner, name, size, err;
position p;
@@
memory_region_init_ram(mr, owner, name, size,
(
- &error_abort
+ &error_fatal
|
err@p
)
);
@script:python@
p << r.p;
@@
print "%s:%s:%s" % (p[0].file, p[0].line, p[0].column)
When the last argument is &error_abort, it gets replaced by
&error_fatal. This is the fix.
If the last argument is anything else, its position is reported. This
lets us check the fix is complete. Four positions get reported:
* ram_backend_memory_alloc()
Error is passed up the call chain, ultimately through
user_creatable_complete(). As far as I can tell, it's callers all
handle the error sanely.
* fsl_imx25_realize(), fsl_imx31_realize(), dp8393x_realize()
DeviceClass.realize() methods, errors handled sanely further up the
call chain.
We're good. Test case again behaves:
$ qemu-system-x86_64 -m 10000000
qemu-system-x86_64: cannot set up guest memory 'pc.ram': Cannot allocate memory
[Exit 1 ]
The next commits will repair the rest of commit ef701d7's damage.

hmp: Allow for error message hints on HMP
Commits 7216ae3d and d2828429 disabled some error message hints,
all because a change to use modern error reporting meant that the
hint would be output prior to the actual error. Fix this by making
hints a first-class member of Error.
For example, we are now back to the pleasant:
$ qemu-system-x86_64 --nodefaults -S --vnc :0 --chardev null,id=,
qemu-system-x86_64: --chardev null,id=,: Parameter 'id' expects an identifier
Identifiers consist of letters, digits, '-', '.', '_', starting with a letter.

error: only prepend timestamp on stderr
The -msg timestamp=on option prepends a timestamp to error messages.
This is useful on stderr where it allows users to identify when an error
was raised.
Timestamps do not make sense on the monitor since error_report() is
called in response to a synchronous monitor command and the user already
knows "when" the command was issued. Additionally, the rest of the
monitor conversation lacks timestamps so the error timestamp cannot be
correlated with other activity.
Only prepend timestamps on stderr. This fixes libvirt's 'drive_del'
processing, which did not expect a timestamp. Other QEMU monitor
clients are probably equally confused by timestamps on monitor error
messages.

target-mips: improve exception handling
This patch improves exception handling in MIPS.
Instructions generate several types of exceptions.
When exception is generated, it breaks the execution of the current
translation block. Implementation of the exceptions handling does not
correctly restore icount for the instruction which caused the exception.
In most cases icount will be decreased by the value equal to the size of
TB. This patch passes pointer to the translation block internals to the
exception handler. It allows correct restoring of the icount value.

target-mips: fix corner case in TLBWR causing QEMU to hang
cpu_mips_get_random() function is used to generate a random index from
CP0.Wired to TLBSize-1 range. Current implementation avoids generating
the same as before value, hence the while loop. If the guest sets
CP0.Wired to TLBSize-1 (which actually does not sound to be very
practical) QEMU will get stuck in the loop infinitely as we always
generate the same index.

pic32: use LCG algorithm for generated random index of TLBWR instruction
The LFSR algorithm, used for generating random TLB indexes for TLBWR
instruction, was inclined to produce a degenerate sequence in some cases.
For example, for 16-entry TLB size and Wired=1, it gives: 15, 6, 7, 2,
7, 2, 7, 2, 7, 2, 7, 2, 7, 2, 7, 2, 7, 2, 7, 2, 7, 2, 7, 2, 7, 2, 7, 2...
When replaced with LCG algorithm from ISO/IEC 9899 standard, the sequence
looks much better, with about the same computational effort needed.

ide: unify io_buffer_offset increments
IDEState's io_buffer_offset was originally added to keep track of offsets
in AHCI rather exclusively, but it was added to IDEState instead of an
AHCI-specific structure.
AHCI fakes all PIO transfers using DMA and a scatter-gather list. When
the core or atapi layers invoke HBA-specific mechanisms for transfers,
they do not always know that it is being backed by DMA or a sglist, so
this offset is not always updated by the HBA code everywhere.
If we modify it in dma_buf_commit, however, any HBA that needs to use
this offset to manage operating on only part of a sglist will have
access to it.
This will fix ATAPI PIO transfers performed through the AHCI HBA,
which were previously not modifying this value appropriately.
This will fix ATAPI PIO transfers larger than one sector.

net: smc91c111: flush packets on RCR register changes
The SOFT_RST or RXEN in the control register can be used as a condition
to unblock the net layer via can_receive(). So check for possible
flushes on RCR changes. This will drop all pending packets on soft
reset or disable which is the functional intent of the can_receive()
logic.

net: smc91c111: gate can_receive() on rx FIFO having a slot
Return false from can_receive() when the FIFO doesn't have a free RX
slot. This fixes a bug in the current code where the allocated buffer
is freed before the fifo pop, triggering a premature flush of queued RX
packets. It also will handle a corner case, where the guest manually
frees the allocated buffer before popping the rx FIFO (hence it is not
enough to just delay the flush_queued_packets()).

qemu-char: Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T). Same Coccinelle semantic patch as in commit b45c03f.

update-linux-headers: copy standard-headers files one by one
cp_virtio is called for both the asm-s390/ and linux/ directories,
so it looks for pci_regs.h and input.h files in asm-s390/ too. This
makes little sense. In the next patch we will have the opposite
problem; we want to add asm-x86/hyperv.h, and there's also a
linux/hyperv.h file with unwanted dependencies on additional Linux
uapi headers. We do not want to copy linux/hyperv.h.
The solution is to make cp_virtio (now renamed to cp_portable) copy
one file only, instead of using the "find" command, and call it multiple
times. The new function is really just a reindentation of the old one.

pci: remove Link Training error from AER error list
The spec says:
Undefined – The value read from this bit is
undefined. In previous versions of this
specification, this bit was used to indicate a Link
Training Error. System software must ignore the
value read from this bit. System software is
permitted to write any value to this bit.
Do not allow injecting it.

ui: convert VNC server to use QCryptoTLSSession
Switch VNC server over to using the QCryptoTLSSession object
for the TLS session. This removes the direct use of gnutls
from the VNC server code. It also removes most knowledge
about TLS certificate handling from the VNC server code.
This has the nice effect that all the CONFIG_VNC_TLS
conditionals go away and the user gets an actual error
message when requesting TLS instead of it being silently
ignored.
With this change, the existing configuration options for
enabling TLS with -vnc are deprecated.
Old syntax for anon-DH credentials:
-vnc hostname:0,tls
New syntax:
-object tls-creds-anon,id=tls0,endpoint=server \
-vnc hostname:0,tls-creds=tls0
Old syntax for x509 credentials, no client certs:
-vnc hostname:0,tls,x509=/path/to/certs
New syntax:
-object tls-creds-x509,id=tls0,dir=/path/to/certs,endpoint=server,verify-peer=no \
-vnc hostname:0,tls-creds=tls0
Old syntax for x509 credentials, requiring client certs:
-vnc hostname:0,tls,x509verify=/path/to/certs
New syntax:
-object tls-creds-x509,id=tls0,dir=/path/to/certs,endpoint=server,verify-peer=yes \
-vnc hostname:0,tls-creds=tls0
This aligns VNC with the way TLS credentials are to be
configured in the future for chardev, nbd and migration
backends. It also has the benefit that the same TLS
credentials can be shared across multiple VNC server
instances, if desired.
If someone uses the deprecated syntax, it will internally
result in the creation of a 'tls-creds' object with an ID
based on the VNC server ID. This allows backwards compat
with the CLI syntax, while still deleting all the original
TLS code from the VNC server.

crypto: introduce new module for handling TLS sessions
Introduce a QCryptoTLSSession object that will encapsulate
all the code for setting up and using a client/sever TLS
session. This isolates the code which depends on the gnutls
library, avoiding #ifdefs in the rest of the codebase, as
well as facilitating any possible future port to other TLS
libraries, if desired. It makes use of the previously
defined QCryptoTLSCreds object to access credentials to
use with the session. It also includes further unit tests
to validate the correctness of the TLS session handshake
and certificate validation. This is functionally equivalent
to the current TLS session handling code embedded in the
VNC server, and will obsolete it.

crypto: add sanity checking of TLS x509 credentials
If the administrator incorrectly sets up their x509 certificates,
the errors seen at runtime during connection attempts are very
obscure and difficult to diagnose. This has been a particular
problem for people using openssl to generate their certificates
instead of the gnutls certtool, because the openssl tools don't
turn on the various x509 extensions that gnutls expects to be
present by default.
This change thus adds support in the TLS credentials object to
sanity check the certificates when QEMU first loads them. This
gives the administrator immediate feedback for the majority of
common configuration mistakes, reducing the pain involved in
setting up TLS. The code is derived from equivalent code that
has been part of libvirt's TLS support and has been seen to be
valuable in assisting admins.
It is possible to disable the sanity checking, however, via
the new 'sanity-check' property on the tls-creds object type,
with a value of 'no'.
Unit tests are included in this change to verify the correctness
of the sanity checking code in all the key scenarios it is
intended to cope with. As part of the test suite, the pkix_asn1_tab.c
from gnutls is imported. This file is intentionally copied from the
(long since obsolete) gnutls 1.6.3 source tree, since that version
was still under GPLv2+, rather than the GPLv3+ of gnutls >= 2.0.

crypto: introduce new base module for TLS credentials
Introduce a QCryptoTLSCreds class to act as the base class for
storing TLS credentials. This will be later subclassed to provide
handling of anonymous and x509 credential types. The subclasses
will be user creatable objects, so instances can be created &
deleted via 'object-add' and 'object-del' QMP commands respectively,
or via the -object command line arg.
If the credentials cannot be initialized an error will be reported
as a QMP reply, or on stderr respectively.
The idea is to make it possible to represent and manage TLS
credentials independently of the network service that is using
them. This will enable multiple services to use the same set of
credentials and minimize code duplication. A later patch will
convert the current VNC server TLS code over to use this object.
The representation of credentials will be functionally equivalent
to that currently implemented in the VNC server with one exception.
The new code has the ability to (optionally) load a pre-generated
set of diffie-hellman parameters, if the file dh-params.pem exists,
whereas the current VNC server will always generate them on startup.
This is beneficial for admins who wish to avoid the (small) time
sink of generating DH parameters at startup and/or avoid depleting
entropy.

crypto: move crypto objects out of libqemuutil.la
Future patches will be adding more crypto related APIs which
rely on QOM infrastructure. This creates a problem, because
QOM relies on library constructors to register objects. When
you have a file in a static .a library though which is only
referenced by a constructor the linker is dumb and will drop
that file when linking to the final executable :-( The only
workaround for this is to link the .a library to the executable
using the -Wl,--whole-archive flag, but this creates its own
set of problems because QEMU is relying on lazy linking for
libqemuutil.a. Using --whole-archive majorly increases the
size of final executables as they now contain a bunch of
object code they don't actually use.
The least bad option is to thus not include the crypto objects
in libqemuutil.la, and instead define a crypto-obj-y variable
that is referenced directly by all the executables that need
this code (tools + softmmu, but not qemu-ga). We avoid pulling
entire of crypto-obj-y into the userspace emulators as that
would force them to link to gnutls too, which is not required.

gtk: use setlocale() for LC_MESSAGES only
The QEMU code is not internationalized and assumes that it runs under
the C locale, but if we use the GTK+ UI we'll end up importing the
locale settings from the environment. This can break things, such as
the JSON generator and iotest 120 in locales that use a decimal comma.
We do however have translations for a few simple strings for the GTK+
menu items, so in order to run QEMU using the C locale, and yet have a
translated UI let's use setlocale() for LC_MESSAGES only.

qapi: allow override of default enum prefix naming
The camel_to_upper() method applies some heuristics to turn
a mixed case type name into an all-uppercase name. This is
used for example, to generate enum constant name prefixes.
The heuristics don't also generate a satisfactory name
though. eg
{ 'enum': 'QCryptoTLSCredsEndpoint',
'data': ['client', 'server']}
Results in Q_CRYPTOTLS_CREDS_ENDPOINT_CLIENT. This has
an undesirable _ after the initial Q and is missing an
_ between the CRYPTO & TLS strings.
Rather than try to add more and more heuristics to try
to cope with this, simply allow the QAPI schema to
specify the desired enum constant prefix explicitly.
eg
{ 'enum': 'QCryptoTLSCredsEndpoint',
'prefix': 'QCRYPTO_TLS_CREDS_ENDPOINT',
'data': ['client', 'server']}
Now gives the QCRYPTO_TLS_CREDS_ENDPOINT_CLIENT name.

qcow2: Make qcow2_alloc_bytes() more explicit
In case of -EAGAIN returned by update_refcount(), we should discard the
cluster offset we were trying to allocate and request a new one, because
in theory that old offset might now be taken by a refcount block.
In practice, this was not the case due to update_refcount() generally
returning strictly monotonic increasing cluster offsets. However, this
behavior is not set in stone, and it is also not obvious when looking at
qcow2_alloc_bytes() alone, so we should not rely on it.

vmdk: Fix next_cluster_sector for compressed write
When the VMDK is streamOptimized (or compressed), the
next_cluster_sector must not be incremented by a fixed number of
sectors. Instead of this, it must be rounded up to the next consecutive
sector. Fixing this results in much smaller compressed images.

qcow2: Make size_to_clusters() return uint64_t
Sadly, some images may have more clusters than what can be represented
using a plain int. We should be prepared for that case (in
qcow2_check_refcounts() we actually were trying to catch that case, but
since size_to_clusters() truncated the returned value, that check never
did anything useful).

64-bit input in one call, this simplifies the code.

target-arm: Eliminate unnecessary zero-extend in disas_bitfield
For !SF, this initial ext32u can't be optimized away by the
current TCG code generator. (It would require backward bit
liveness propagation.)
But since the range of bits for !SF are already constrained by
unallocated_encoding, we'll never reference the high bits anyway.

target-arm: Share all common TCG temporaries
This is a bug fix for aarch64. At present, we have branches using
the 32-bit (translate.c) versions of cpu_[NZCV]F, but we set the flags
using the 64-bit (translate-a64.c) versions of cpu_[NZCV]F. From
the view of the TCG code generator, these are unrelated variables.
The bug is hard to see because we currently only read these variables
from branches, and upon reaching a branch TCG will first spill live
variables and then reload the arguments of the branch. Since the
32-bit versions were never live until reaching the branch, we'd re-read
the data that had just been spilled from the 64-bit versions.
There is currently no such problem with the cpu_exclusive_* variables,
but there's no point in tempting fate.

target-sh4: improve shad instruction
The SH4 shad instruction can shift in both direction, depending on the
sign of the shift. This is currently implemented using branches, which
is not really efficient and prevents the optimizer to do its job. In
practice it is often used with a constant loaded in a register just
before.
Simplify the implementation by computing both the value shifted to the
left and to the right, and then selecting the correct one with a
movcond. As with a negative value the shift amount can go up to 32 which
is undefined, we shift the value in two steps.

target-sh4: improve cmp/str instruction
Instead of testing bytes one by one, we can use the following trick
from https://graphics.stanford.edu/~seander/bithacks.html:
haszero(v) = (v - 0x01010101) & ~v & 0x80808080
The subexpression v - 0x01010101, evaluates to a high bit set in any
byte whenever the corresponding byte in v is zero or greater than 0x80.
The sub-expression ~v & 0x80808080 evaluates to high bits set in bytes
where the byte of v doesn't have its high bit set (so the byte was less
than 0x80). Finally, by ANDing these two sub-expressions the result is
the high bits set where the bytes in v were zero, since the high bits
set due to a value greater than 0x80 in the first sub-expression are
masked off by the second.

All targets ignore it for now, and all other callers pass "false".
This will allow targets who wish to split the mmu index between

This will let us print options in a format that the user would actually

prepending a spurious comma at the beginning of the list, or quoting

* write and id=, if the option has an id
* do not print separator before the first element

i6300esb: fix timer overflow
We use muldiv64() to compute the time to wait:
timeout = muldiv64(get_ticks_per_sec(), timeout, 33000000);
but get_ticks_per_sec() is 10^9 (30 bit value) and timeout
is a 35 bit value.
Whereas muldiv64 is:
uint64_t muldiv64(uint64_t a, uint32_t b, uint32_t c)
So we loose 3 bits of timeout.
Swapping get_ticks_per_sec() and timeout fixes it.
We can also replace it by a multiplication by 30 ns,
but this changes PCI clock frequency from 33MHz to 33.333333MHz
and we need to do this on all the QEMU PCI devices (later...)

xen/pt: Remove XenPTReg->data field.
We do not want to have two entries to cache the guest configuration
registers: XenPTReg->data and dev.config. Instead we want to use
only the dev.config.
To do without much complications we rip out the ->data field
and replace it with an pointer to the dev.config. This way we
have the type-checking (uint8_t, uint16_t, etc) and as well
and pre-computed location.
Alternatively we could compute the offset in dev.config by
using the XenPTRRegInfo and XenPTRegGroup every time but
this way we have the pre-computed values.
This change also exposes some mis-use:
- In 'xen_pt_status_reg_init' we used u32 for the Capabilities Pointer
register, but said register is an an u16.
- In 'xen_pt_msgdata_reg_write' we used u32 but should have only use u16.

It should never happen, but in case it does (an developer adds

size) we want to report. The code will only write up to
reg->size so there is no runtime danger of the register spilling
across other ones - however to catch this sort of thing
we still return an error.

xen/pt: Sync up the dev.config and data values.
For a passthrough device we maintain a state of emulated
registers value contained within d->config. We also consult
the host registers (and apply ro and write masks) whenever
the guest access the registers. This is done in xen_pt_pci_write_config
and xen_pt_pci_read_config.
Also in this picture we call pci_default_write_config which
updates the d->config and if the d->config[PCI_COMMAND] register
has PCI_COMMAND_MEMORY (or PCI_COMMAND_IO) acts on those changes.
On startup the d->config[PCI_COMMAND] are the host values, not
what the guest initial values should be, which is exactly what
we do _not_ want to do for 64-bit BARs when the guest just wants
to read the size of the BAR. Huh you say?
To get the size of 64-bit memory space BARs, the guest has
to calculate ((BAR[x] & 0xFFFFFFF0) + ((BAR[x+1] & 0xFFFFFFFF) << 32))
which means it has to do two writes of ~0 to BARx and BARx+1.
prior to this patch and with XSA120-addendum patch (Linux kernel)
the PCI_COMMAND register is copied from the host it can have
PCI_COMMAND_MEMORY bit set which means that QEMU will try to
update the hypervisor's P2M with BARx+1 value to ~0 (0xffffffff)
(to sync the guest state to host) instead of just having
xen_pt_pci_write_config and xen_pt_bar_reg_write apply the
proper masks and return the size to the guest.
To thwart this, this patch syncs up the host values with the
guest values taking into account the emu_mask (bit set means
we emulate, PCI_COMMAND_MEMORY and PCI_COMMAND_IO are set).
That is we copy the host values - masking out any bits which
we will emulate. Then merge it with the initial emulation register
values. Lastly this value is then copied both in
dev.config _and_ XenPTReg->data field.
There is also reg->size accounting taken into consideration
that ends up being used in patch.
xen/pt: Check if reg->init function sets the 'data' past the reg->size
This fixes errors such as these:

Also we swap from xen_host_pci_long to using xen_host_pci_get_[byte,word,long].
Otherwise we get:
xen_pt_config_reg_init: Offset 0x0004 mismatch! Emulated=0x0000, host=0x2300017, syncing to 0x2300014.
xen_pt_config_reg_init: Error: Offset 0x0004:0x2300014 expands past register size(2)!
which is not surprising. We read the value as an 32-bit (from host),
then operate it as a 16-bit - and the remainder is left unchanged.
We end up writing the value as 16-bit (so 0014) to dev.config
(as we use proper xen_set_host_[byte,word,long] so we don't spill
to other registers) but in XenPTReg->data it is as 32-bit (0x2300014)!
It is harmless as the read/write functions end up using an size mask
and never modify the bits past 16-bit (reg->size is 2).
This patch fixes the warnings by reading the value using the
proper size.
Note that the check for size is still left in-case the developer
sets bits past the reg->size in the ->init routines. The author
tried to fiddle with QEMU_BUILD_BUG to make this work but failed.

xen/pt: Use xen_host_pci_get_[byte|word] instead of dev.config
During init time we treat the dev.config area as a cache
of the host view. However during execution time we treat it
as guest view (by the generic PCI API). We need to sync Xen's
code to the generic PCI API view. This is the first step
by replacing all of the code that uses dev.config or
pci_get_[byte|word] to get host value to actually use the
xen_host_pci_get_[byte|word] functions.
Interestingly in 'xen_pt_ptr_reg_init' we also needed to swap
reg_field from uint32_t to uint8_t - since the access is only
for one byte not four bytes. We can split this as a seperate
patch however we would have to use a cast to thwart compiler
warnings in the meantime.
We also truncated 'flags' to 'flag' to make the code fit within
the 80 characters.

xen: use errno instead of rc for xc_domain_add_to_physmap
In Xen 4.6 commit cd2f100f0f61b3f333d52d1737dd73f02daee592
"libxc: Fix do_memory_op to return negative value on errors"
made the libxc API less odd-ball: On errors, return value is
-1 and error code is in errno. On success the return value
is either 0 or an positive value.
Since we could be running with an old toolstack in which the
Exx value is in rc or the newer, we add an wrapper around
the xc_domain_add_to_physmap (called xen_xc_domain_add_to_physmap)
which will always return the EXX.
Xen 4.6 did not change the libxc functions mentioned (same parameters)
so we piggyback on the fact that Xen 4.6 has a new function:
commit 504ed2053362381ac01b98db9313454488b7db40 "tools/libxc: Expose
new hypercall xc_reserved_device_memory_map" and check for that.

xen/HVM: atomically access pointers in bufioreq handling
The number of slots per page being 511 (i.e. not a power of two) means
that the (32-bit) read and write indexes going beyond 2^32 will likely
disturb operation. The hypervisor side gets I/O req server creation
extended so we can indicate that we're using suitable atomic accesses
where needed, allowing it to atomically canonicalize both pointers when
both have gone through at least one cycle.
The Xen side counterpart (which is not a functional prereq to this
change, albeit a build one) went in already (commit b7007bc6f9).

igd gfx passthrough: create a isa bridge
Currently IGD drivers always need to access PCH by 1f.0. But we
don't want to poke that directly to get ID, and although in real
world different GPU should have different PCH. But actually the
different PCH DIDs likely map to different PCH SKUs. We do the
same thing for the GPU. For PCH, the different SKUs are going to
be all the same silicon design and implementation, just different
features turn on and off with fuses. The SW interfaces should be
consistent across all SKUs in a given family (eg LPT). But just
same features may not be supported.
Most of these different PCH features probably don't matter to the
Gfx driver, but obviously any difference in display port connections
will so it should be fine with any PCH in case of passthrough.
So currently use one PCH version, 0x8c4e, to cover all HSW(Haswell)
scenarios, 0x9cc3 for BDW(Broadwell).

error: On abort, report where the error was created
This is particularly useful when we abort in error_propagate(),
because there the stack backtrace doesn't lead to where the error was
created. Looks like this:
Unexpected error in parse_block_error_action() at .../qemu/blockdev.c:322:
qemu-system-x86_64: -drive if=none,werror=foo: 'foo' invalid write error action
Aborted (core dumped)
Note: to get this example output, I monkey-patched drive_new() to pass
&error_abort to blockdev_init().
To keep the error handling boiler plate from growing even more, all
error_setFOO() become macros expanding into error_setFOO_internal()
with additional __FILE__, __LINE__, __func__ arguments. Not exactly
pretty, but it works.
The macro trickery breaks down when you take the address of an
error_setFOO(). Fortunately, we do that in just one place: qemu-ga's
Windows VSS provider and requester DLL wants to call
error_setg_win32() through a function pointer "to avoid linking glib
to the DLL". Use error_setg_win32_internal() there. The use of the
function pointer is already wrapped in a macro, so the churn isn't
bad.
Code size increases by some 35KiB for me (0.7%). Tolerable. Could be
less if we passed relative rather than absolute source file names to
the compiler, or forwent reporting __func__.

qga/vss-win32: Document the DLL requires non-null errp
requester.cpp uses this pattern to receive an error and pass it on to
the caller (err_is_set() macro peeled off for clarity):
... code that may set errset->errp ...
if (errset->errp && *errset->errp) {
... handle error ...
}
This breaks when errset->errp is null. As far as I can tell, it
currently isn't, so this is merely fragile, not actually broken.
The robust way to do this is to receive the error in a local variable,
then propagate it up, like this:
Error *err = NULL;
... code that may set err ...
if (err)
... handle error ...
error_propagate(errset->errp, err);
}

qga: Clean up unnecessarily dirty casts
qga_vss_fsfreeze() casts error_set_win32() from
void (*)(Error **, int, ErrorClass, const char *, ...)
to
void (*)(void **, int, int, const char *, ...)
The result is later called. Since the two types are not compatible,
the call is undefined behavior. It works in practice anyway.
However, there's no real need for trickery here. Clean it up as
follows:
* Declare struct Error, and fix the first parameter.
* Switch to error_setg_win32(). This gets rid of the troublesome
ErrorClass parameter. Requires converting error_setg_win32() from
macro to function, but that's trivially easy, because this is the
only user of error_set_win32().

"unorthodox" PCI BDF notation in at least the stderr trace backend. For
example, the four BARs of a QXL video card at 00:01.0 (bus 0, slot 1,

pc: memhotplug: fix incorrectly set reserved-memory-end
reserved-memory-end tells firmware address from which
it could start treating memory as PCI address space
and map PCI BARs after it to avoid collisions with
RAM.
Currently it is incorrectly pointing to address where
hotplugged memory range starts which could redirect
hotplugged RAM accesses to PCI BARs when firmware
maps them over RAM or viceverse.
Fix this by pointing reserved-memory-end to the end
of memory hotplug area.

pci: Fix pci_device_iommu_address_space() bus propagation
he current code walks up the bus tree for an iommu, however it passes
to the iommu_fn() callback the bus/devfn of the immediate child of
the level where the callback was found, rather than the original
bus/devfn where the search started from.
This prevents iommu's like POWER8 (and in fact also Q35) to properly
provide an address space for a subset of devices that aren't immediate
children of the iommu.
PCIe carries the originator bdfn acccross to the iommu on all DMA
transactions, so we must be able to properly identify devices at all
levels.
This changes the function pci_device_iommu_address_space() to pass
the original pointers to the iommu_fn() callback instead.

cutils: work around platform differences in strto{l,ul,ll,ull}
Linux returns 0 if no conversion was made, while OS X and presumably
the BSDs return EINVAL. The OS X convention rejects more invalid
inputs, so convert to it and adjust the test case.
Windows returns 1 from strtoul and strtoull (instead of -1) for
negative out-of-range input; fix it up.

tb_lock has to be taken inside the mmap_lock (example:

configure: Add support for jemalloc
This adds "--enable-jemalloc" and "--disable-jemalloc" to allow linking
to jemalloc memory allocator.
We have already tcmalloc support,
but it seem to not working well with a lot of iothreads/disks.
The main problem is that tcmalloc use a shared thread cache of 16MB
by default.
With more threads, this cache is shared, and some bad garbage collections
can occur if the cache is too low.
It's possible to tcmalloc cache increase it with a env var:
TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES=256MB
With default 16MB, performances are really bad with more than 2 disks.
Increasing to 256MB, it's helping but still have problem with 16 disks/iothreads.
Jemalloc don't have performance problem with default configuration.
Here the benchmark results in iops of 1 qemu vm randread 4K iodepth=32,
with rbd block backend (librbd is doing a lot of memory allocation),

Makefile.target: include top level build dir in vpath
Using ccache with CCACHE_BASEDIR set to $(SRC_PATH) or a parent will
rewrite all absolute paths to relative paths. This interacts poorly with
QEMU's two-level build directory scheme. For example, lets say
BUILD_DIR=$(SRC_PATH)/build so build/blockdev.d will contain:
blockdev.o: ../blockdev.c ../include/sysemu/block-backend.h \
Now the target build under build/x86_64-softmmu or similar will depend
on ../blockdev.o which in turn will get make to source ../blockdev.d to
check its dependencies. Since make always considers paths relative to
the current working directory rather than the makefile the path appeared
in the relative path to ../blockdev.c is useless.
This change simply adds the top level build directory to vpath so paths
relative to the source directory, top build directory, and target build
directory all work just fine.

tcg: signal-free qemu_cpu_kick
Signals are slow and do not exist on Win32. The previous patches
have done most of the legwork to introduce memory barriers (some
of them were even there already for the sake of Windows!) and
we can now set the flags directly in the iothread.
qemu_cpu_kick_thread is not used anymore on TCG, since the TCG thread is
never outside usermode while the CPU is running (not halted). Instead run
the content of the signal handler (now in qemu_cpu_kick_no_halt) directly.
qemu_cpu_kick_no_halt is also used in qemu_mutex_lock_iothread to avoid
the overhead of qemu_cond_broadcast.

use qemu_cpu_kick instead of cpu_exit or qemu_cpu_kick_thread
Use the same API to trigger interruption of a CPU, no matter if
under TCG or KVM. There is no difference: these calls come from
the CPU thread, so the qemu_cpu_kick calls will send a signal
to the running thread and it will be processed synchronously,
just like a call to cpu_exit. The only difference is in the
overhead, but neither call to cpu_exit (now qemu_cpu_kick)
is in a hot path.

i8257: rewrite DMA_schedule to avoid hooking into the CPU loop
The i8257 DMA controller uses an idle bottom half, which by default
does not cause the main loop to exit. Therefore, the DMA_schedule
function is there to ensure that the CPU relinquishes the iothread
mutex to the iothread.
However, this is not enough since the iothread will call
aio_compute_timeout() and go to sleep again. In the iothread
world, forcing execution of the idle bottom half is much simpler,
and only requires a call to qemu_notify_event(). Do it, removing
the need for the "cpu_request_exit" pseudo-irq. The next patch
will remove it.

hw/intc/arm_gic_common: Configure IRQs as NS if doing direct NS kernel boot
If we directly boot a kernel in NonSecure on a system where the GIC
supports the security extensions then we must cause the GIC to
configure its interrupts into group 1 (NonSecure) rather than the
usual group 0, and with their initial priority set to the highest
NonSecure priority rather than the usual highest Secure priority.
Otherwise the guest kernel will be unable to use any interrupts.
Implement this behaviour, controlled by a flag which we set if
appropriate when the ARM bootloader code calls our ARMLinuxBootIf

hw/arm: new interface for devices which need to behave differently for kernel boot
For ARM we have a little minimalist bootloader in hw/arm/boot.c which
takes the place of firmware if we're directly booting a Linux kernel.
Unfortunately a few devices need special case handling in this situation
to do the initialization which on real hardware would be done by
firmware. (In particular if we're booting a kernel in NonSecure state
then we need to make a TZ-aware GIC put all its interrupts into Group 1,
or the guest will be unable to use them.)
Create a new QOM interface which can be implemented by devices which
need to do something different from their default reset behaviour.
The callback will be called after machine initialization and before
first reset.

armv7m_nvic: Implement ICSR without using internal GIC state
Change the implementation of the Interrupt Control and State Register
in the v7M NVIC to not use the running_irq and last_active internal
state fields in the GIC. These fields don't correspond to state in
a real GIC and will be removed soon.
The changes to the ICSR are:
* the VECTACTIVE field is documented as identical to the IPSR[8:0]
field, so implement it that way
* implement RETTOBASE via looking at the active state bits

cpus.c: qemu_mutex_lock_iothread fix race condition at cpu thread init
When QEMU starts the RCU thread executes qemu_mutex_lock_thread
causing error "qemu:qemu_cpu_kick_thread: No such process" and exits.
This isn't occur frequently but in glibc the thread id can exist and
this not guarantee that the thread is on active/running state. If is
inserted a sleep(1) after newthread assignment [1] the issue appears.
So not make assumption that thread exist if first_cpu->thread is set
then change the validation of cpu to created that is set into cpu
threads (kvm, tcg, dummy).

The restrictions for memory calculation belong to the sclp device.
Let's move the calculation to that point, so we are able to unify it for

It performs the calculation and safely stores it in the machine, where
other parts of the system can access an reuse it.
The memory hotplug device is now only created when it is really needed.

s390/sclp: ignore memory hotplug operations if it is disabled
If no memory hotplug device was created, the sclp command facility is

memory hotplug and should correctly report SCLP_RC_INVALID_SCLP_COMMAND
if any such command is executed.
This gets rid of these ugly asserts that could have been triggered

s390/sclp: temporarily fix unassignment/reassignment of memory subregions
Commit 374f2981d1f1 ("memory: protect current_map by RCU") broke
unassignment of standby memory on s390x. Looks like that the new
parallelism allows races with our (semi broken) memory hotplug code. The
flatview_unref() can now be executed after our unparenting. Therefore
memory_region_unref() tries to unreference the MemoryRegion itself instead
of the parent.
In theory, MemoryRegions are now bound to separate devices that control
their lifetime. We don't have this yet, so we really want to control their
lifetime manually.
This patch fixes it temporarily, until we have a proper rework. The only
drawback is that they won't pop up in "info qom-tree", but that's better
than qemu crashes.
We have to release the reference to a memory region after a
memory_region_find, as it automatically takes a reference. As we're now
able to reassign memory, the MemoryRegion is in fact deleted (otherwise
vmstate_register_ram() would complain).

s390/sclp: rework sclp event facility initialization + device realization
The current code only works by chance. The event facility is a sysbus
device, but specifies in its class structure as parent the DeviceClass
(instead of a device class).
The init function in return lies therefore at the same position as
the init function of SysBusDeviceClass and gets triggered instead -
a very bad idea of doing that (e.g. the parameter types don't match).
Let's bring the initialization code up to date, initializing the event
facility + child events in .instance_init and moving the realization of
the child events out of the init call, into the realization step.
Device realization is now automatically performed when the event facility
itself is realized. That realization implicitly triggers realization of
the child bus, which in turn initializes the events.
Please note that we have to manually propagate the realization of the bus
children, common code still has a TODO set for that task.

Let's get rid of this strange local variable + irq logic and

We could introduce proper QOM class + state for the cpu hotplug device,
however that would result in too much overhead for a simple
"trigger_signal" function.
Also remove one unnecessary class function initialization.

s390x/kvm: make setting of in-kernel irq routes more efficient
When we add new adapter routes we call kvm_irqchip_add_route() for every
virtqueue and in the same step also do the KVM_SET_GSI_ROUTING ioctl.
This is unnecessary costly as the interface allows us to set multiple
routes in one go. Let's first add all routes to the table stored in the
global kvm_state and then do the ioctl to commit the routes to the
in-kernel irqchip.
This saves us several ioctls to the kernel where for each call a list
is reallocated and populated.

s390x/event-facility: fix location of receive mask
For read event mask, we assumed that the layout of the sccb was
|sccb header|event buffer header|receive mask|...|
The correct layout, however, is
|sccb header|receive mask|...|
as in-buffer and
|sccb header|event buffer header|...|
as out-buffer.
Fix this: This makes selective read work.

s390x/css: start with cleared cstat/dstat
When executing the start function, we should start with a clear state
regarding subchannel and device status; it is easy to forget updating one
of them after the ccw has been processed.
Note that we don't need to care about resetting the various control
fields: They are cleared by tsch(), and if they were still pending,
we wouldn't be able to execute the start function in the first
place.
Also note that we don't want to clear cstat/dstat if a suspended
subchannel is resumed.
This fixes a bug where we would continue to present channel-program
check in cstat even though later ccw requests for the subchannel
finished without error (i.e. cstat should be 0).

Make pow2ceil() and pow2floor() inline
Since the pow2floor() function is now used in a hot code path,
make it inline; for consistency, provide pow2ceil() as an inline
function too.
Because these functions use ctz64() we have to put the inline
versions into host-utils.h, so they have access to ctz64(),
and move the inline is_power_of_2() along with them.
We then need to include host-utils.h from qemu-common.h so that
the files which use these functions via qemu-common.h still have
access to them.

hw/pci: Use pow2ceil() rather than hand-calculation
A couple of places in hw/pci use an inline calculation to round a
size up to the next largest power of 2. We have a utility routine
for this, so use it.
(The behaviour of the old code is different if the size value
is 0 -- it would leave it as 0 rather than rounding up to 1,
but in both cases we know the size can't be 0.
In the case where the size value had bit 31 set, the old code
would invoke undefined behaviour; the new code will give a
result of 0. Presumably that could never happen either.)

target-arm/arm-semi.c: Factor out repeated 'return env->regs[0]'
Factor out a repeated pattern in the semihosting code:
gdb_do_syscall(arm_semi_cb, "system,%s", arg0, (int)arg1+1);
/* arm_semi_cb sets env->regs[0] to the syscall return value */
return env->regs[0];
For A64 the return value will go in a different register; pull
the sequence out into its own function that passes the return
value in a static variable rather than overloading regs[0]
for the purpose, so the code will work on both A32/T32 and A64.
Note that the lack-of-synchronization bug noted in the FIXME
comment is not introduced by this commit, but was already present.

arm: Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T).

docs: document how to configure the qcow2 L2/refcount caches
QEMU has options to configure the size of the L2 and refcount
caches for the qcow2 format. However, choosing the right sizes for
a particular disk image is not a straightforward operation since
the ratio between the cache size and the allocated disk space is
not obvious and depends on the size of the cluster and the refcount
entries.
This document attempts to give an overview of both caches and how to
configure their sizes.

qcow2: add option to clean unused cache entries after some time
This adds a new 'cache-clean-interval' option that cleans all qcow2
cache entries that haven't been used in a certain interval, given in
seconds.
This allows setting a large L2 cache size so it can handle scenarios
with lots of I/O and at the same time use little memory during periods
of inactivity.
This feature currently relies on MADV_DONTNEED to free that memory, so
it is not useful in systems that don't follow that behavior.

qcow2: mark the memory as no longer needed after qcow2_cache_empty()
After having emptied the cache, the data in the cache tables is no
longer useful, so we can tell the kernel that we are done with it. In
Linux this frees the resources associated with it.
The effect of this can be seen in the HMP commit operation: it moves
data from the top to the base image (and fills both caches), then it
empties the top image. At this point the data in that cache is no
longer needed so it's just wasting memory.

iotests: Do not suppress segfaults in bash tests
Currently, if a qemu/qemu-io/qemu-img/qemu-nbd invocation receives a
segmentation fault, that message is invisible in most cases since the
output is generally filtered and bash suppresses the segmentation fault
notice for any but the last element of a pipe.
Most of the time, the test will then fail anyway because of missing
output, but not necessarily (as happened with test 82 recently).
Fix this by making the corresponding environment variables point to
wrapper functions which execute the respective command in a subshell.
Giving options to qemu/qemu-io/qemu-img and path names with spaces were
broken for the Python tests; this patch "accidentally" fixes that.

067, 071, 081 and 087 need to be updated to accommodate this change.
Use virtio-blk instead of virtio-blk-pci as the device driver for test
case 067. For virtio-blk-pci is the same with virtio-blk as device
driver but other platform such as s390 may not recognize the virtio-blk-pci.
The default devices differ across machines. As the qemu output often
contains these devices (or events for them, like opening a CD tray on
reset), the reference output currently is rather machine-specific.
All existing qemu tests explicitly configure the devices they're working
with, so just pass -nodefaults to qemu by default to disable the default
devices. Update the reference outputs accordingly.

qemu-iotests: qemu machine type support
This patch adds qemu machine type support to the io test suite.
Based on the qemu default machine type and alias of the default machine
type the reference output file can now vary from the default to a
machine specific output file if necessary. When using a machine specific
reference file if the default machine has an alias then use the alias as the output
file name otherwise use the default machine name as the output file name.

qapi: Simplify error reporting for array types
check_type() first checks and peels off the array type, then checks
the element type. For two out of four error messages, it takes pains
to report errors for "array of T" instead of just T. Odd. Let's
examine the errors.
* Unknown element type, e.g.
tests/qapi-schema/args-array-unknown.json:
Member 'array' of 'data' for command 'oops' uses unknown type
'array of NoSuchType'
To make sense of this, you need to know that 'array of NoSuchType'
refers to '[NoSuchType]'. Easy enough. However, simply reporting
Member 'array' of 'data' for command 'oops' uses unknown type
'NoSuchType'
is at least as easy to understand.
* Element type's meta-type is inadmissible, e.g.
tests/qapi-schema/returns-whitelist.json:
'returns' for command 'no-way-this-will-get-whitelisted' cannot
use built-in type 'array of int'
'array of int' is technically not a built-in type, but that's
pedantry. However, simply reporting
'returns' for command 'no-way-this-will-get-whitelisted' cannot
use built-in type 'int'
avoids the issue, and is at least as easy to understand.
* The remaining two errors are unreachable, because the array checking
ensures that value is a string.
Thus, reporting some errors for "array of T" instead of just T works,
but doesn't really improve things. Drop it.

qapi: Document that input visitor semantics are prone to leaks
Most functions that can return a pointer or set an Error ** value
are decent enough to guarantee a NULL return when reporting an error.
Not so with our generated qapi visitor functions. If the caller
is not careful to clean up partially-allocated objects on error,
then the caller suffers a memory leak.
Properly fixing it is probably complex enough to save for a later
day, so merely document it for now.

qapi: Generate a nicer struct for flat unions
The struct generated for a flat union is weird: the members of its
base are at the end, except for the union tag, which is at the
beginning.
Example: qapi-schema-test.json has
{ 'struct': 'UserDefUnionBase',
'data': { 'string': 'str', 'enum1': 'EnumOne' } }
{ 'union': 'UserDefFlatUnion',
'base': 'UserDefUnionBase',
'discriminator': 'enum1',
'data': { 'value1' : 'UserDefA',
'value2' : 'UserDefB',
'value3' : 'UserDefB' } }
We generate:
struct UserDefFlatUnion
{
EnumOne enum1;
union {
void *data;
UserDefA *value1;
UserDefB *value2;
UserDefB *value3;
};
char *string;
};
Change to put all base members at the beginning, unadulterated. Not
only is this easier to understand, it also permits casting the flat
union to its base, if that should become useful.
We now generate:
struct UserDefFlatUnion
{
/* Members inherited from UserDefUnionBase: */
char *string;
EnumOne enum1;
/* Own members: */
union { /* union tag is @enum1 */
void *data;
UserDefA *value1;
UserDefB *value2;
UserDefB *value3;
};
};

qapi-event: Clean up how name of enum QAPIEvent is made
Use c_name() instead of ad hoc code. Doesn't upcase the -p prefix,
which is an improvement in my book. Unbreaks prefix containing '.',
but other funny characters remain broken. To be fixed next.

qapi: Clean up cgen() and mcgen()
Commit 05dfb26 added eatspace stripping to mcgen(). Move it to
cgen(), just in case somebody gets tempted to use cgen() directly
instead of via mcgen().
cgen() indents blank lines. No such lines get generated right now,
but fix it anyway.
We use triple-quoted strings for program text, like this:
'''
Program text
any number of lines
'''
Keeps the program text relatively readable, but puts an extra newline
at either end. mcgen() "fixes" that by dropping the first and last
line outright. Drop only the newlines.
This unmasks a bug in qapi-commands.py: four quotes instead of three.
Fix it up.
Output doesn't change

Routines to save/load guest storage keys are provided. register_savevm is

We prepare the protocol to support more complex parameters. So we will
later be able to support standby memory (having empty holes), compression
and "state live migration" like done for ram.

rtl8139: Fix receive buffer overflow check
rtl8139_do_receive() tries to check for the overflow condition
by making sure that packet_size + 8 does not exceed the
available buffer space. The issue here is that RxBuffAddr,
used to calculate available buffer space, is aligned to a
a 4 byte boundry after every update. So it is possible that
every packet ends up being slightly padded when written
to the receive buffer. This padding is not taken into
account when checking for overflow and we may end up missing
the overflow condition can causing buffer overwrite.
This patch takes alignment into consideration when
checking for overflow condition.

build: qemu-ga: fix VSS dependencies
Currently VSS dll/tlb files for use in w32 builds are only built as a
result of having been added to the general 'tools' target alongside
qemu-ga. This is fine for default make target, but if we build
qemu-ga directly via `make qemu-ga.exe`, the VSS files are not
created.
Fix this by moving the VSS dependencies to qemu-ga.exe directly.
With this move we can move the VSS files back out of 'tools',
and drop the extra handling from MSI target in Makefile.
Now we can build qemu-ga MSI package with:
./configure ...
make qemu-ga.exe
make msi
or simply:
./configure ...
make msi
and no longer need to do a full build beforehand.

configure: qemu-ga: explicitly enable qemu-ga MSI support when probed
Currently, if we don't explicitly disable support for MSI installer
via --disable-guest-agent-msi, the configure variable that tracks
the flag, 'guest_agent_msi', never gets set unless one of the probes
fails. Subsequent code then treats this unset value the same as if it
were a "yes" value (via != "no" style checks).
Instead, set the default "yes" value explicitly after the probes, then
make subsequent code expect the values to be set.
This makes it easier to report on whether or not MSI support was
enabled via probe by looking at the ./configure summary.

configure: qemu-ga: move MSI installer probe after qga probe
MSI probe assumes that qemu-ga support has been probed already, but in
cases where --enable-guest-agent/--disable-guest-agent have not been
passed to configure, qemu-ga support may end up getting enabled later,
as is the case with w32 builds. This leads to MSI probe prematurely
reporting error due to lack of qemu-ga support.
Fix this by moving MSI installer probe after the final qga probes.

qemu-ga: Prevent QEMU-GA VSS provider from being unregistered on MSI reinstall
Previously, running the .msi would unregister the QEMU GA VSS service if QEMU GA was already installed on the machine, and then register it only if QEMU GA was NOT previously installed. This behavior caused the service to be registered only after the INITIAL installation, and any subsequent run of the .msi (to redo, repair, or upgrade the installation) ended in the service being unregistered.
Now, the VSS service is still unregistered if QEMU GA is already installed (so that a fix or an update could be performed) but then it is registered again (if the GA is not being uninstalled) thus finishing the repair/upgrade correctly. Additionally, downgrading is now prevented. If a user would like to downgrade a version, he/she must uninstall the newer version first.

vnc: fix memory corruption (CVE-2015-5225)
The _cmp_bytes variable added by commit "bea60dd ui/vnc: fix potential
memory corruption issues" can become negative. Result is (possibly
exploitable) memory corruption. Reason for that is it uses the stride
instead of bytes per scanline to apply limits.
For the server surface is is actually fine. vnc creates that itself,
there is never any padding and thus scanline length always equals stride.
For the guest surface scanline length and stride are typically identical
too, but it doesn't has to be that way. So add and use a new variable
(guest_ll) for the guest scanline length. Also rename min_stride to
line_bytes to make more clear what it actually is. Finally sprinkle
in an assert() to make sure we never use a negative _cmp_bytes again.

Now we have the ability to flush the TLB only for specific MMU indexes,
update the AArch64 TLB maintenance instruction implementations to only
flush the parts of the TLB they need to, rather than doing full flushes.
We take the opportunity to remove some duplicate functions (the per-asid
tlb ops work like the non-per-asid ones because we don't support
flushing a TLB only by ASID) and to bring the function names in line
with the architectural TLBI operation names.

target-arm: Add CP_ACCESS_TRAP_UNCATEGORIZED_EL2, 3
Some coprocessor register access functions need to be able
to report "trap to EL3 with an 'uncategorized' syndrome";
add the necessary CPAccessResult enum and handling for it.
I don't currently know of any registers that need to trap
to EL2 with the 'uncategorized' syndrome, but adding the
_EL2 enum as well is trivial and fills in what would
otherwise be an odd gap in the handling.

tcg/ppc: Improve unaligned load/store handling on 64-bit backend
Currently, we get to the slow path for any unaligned access in the
backend, because we effectively preserve the bottom address bits
below the alignment requirement when comparing with the TLB entry,
so any non-0 bit there will cause the compare to fail.
For the same number of instructions, we can instead add the access
size - 1 to the address and stick to clearing all the bottom bits.
That means that normal unaligned accesses will not fallback (the HW
will handle them fine). Only when crossing a page boundary well we
end up having a mismatch because we'll end up pointing to the next
page which cannot possibly be in that same TLB entry.

tcg/i386: use softmmu fast path for unaligned accesses
Softmmu unaligned load/stores currently goes through through the slow
path for two reasons:
- to support unaligned access on host with strict alignement
- to correctly handle accesses crossing pages
x86 is only concerned by the second reason. Unaligned accesses are
avoided by compilers, but are not uncommon. We therefore would like
to see them going through the fast path, if they don't cross pages.
For that we can use the fact that two adjacent TLB entries can't contain
the same page. Therefore accessing the TLB entry corresponding to the
first byte, but comparing its content to page address of the last byte
ensures that we don't cross pages. We can do this check without adding
more instructions in the TLB code (but increasing its length by one
byte) by using the LEA instruction to combine the existing move with the
size addition.
On an x86-64 host, this gives a 3% boot time improvement for a powerpc
guest and 4% for an x86-64 guest.

tcg/optimize: optimize temps tracking
The tcg_temp_info structure uses 24 bytes per temp. Now that we emulate
vector registers on most guests, it's not uncommon to have more than 100
used temps. This means we have initialize more than 2kB at least twice
per TB, often more when there is a few goto_tb.
Instead used a TCGTempSet bit array to track which temps are in used in
the current basic block. This means there are only around 16 bytes to
initialize.
This improves the boot time of a MIPS guest on an x86-64 host by around
7% and moves out tcg_optimize from the the top of the profiler list.

tcg/optimize: fix constant signedness
By convention, on a 64-bit host TCG internally stores 32-bit constants
as sign-extended. This is not the case in the optimizer when a 32-bit
constant is folded.
This doesn't seem to have more consequences than suboptimal code
generation. For instance the x86 backend assumes sign-extended constants,
and in some rare cases uses a 32-bit unsigned immediate 0xffffffff
instead of a 8-bit signed immediate 0xff for the constant -1. This is
with a ppc guest:

configure: Don't permit SDL or GTK on OSX
The cocoa GUI frontend assumes it is the only GUI (it redefines
main() so it always gets control before the rest of QEMU), so
it does not play well with other UIs like SDL or GTK. (Mostly
people building QEMU on OSX don't have the necessary dependencies
available for configure to build those other front ends, so
mostly this problem goes unnoticed.)
Make configure automatically disable the SDL and GTK front ends
if the cocoa front end is enabled. (We were sort of attempting
to do this for SDL before, but not in a way that worked very well.)

qemu-common.h: Move muldiv64() to host-utils.h
Move the muldiv64() function from qemu-common.h to host-utils.h.
This puts it together with all the other arithmetic functions
where we provide a version with __int128_t and a fallback
without, and allows headers which need muldiv64() to avoid
including qemu-common.h.
We don't include host-utils from qemu-common.h, to avoid dragging
more things into qemu-common.h than it already has; in practice
everywhere that needs muldiv64() can get it via qemu/timer.h.

target-alpha: Use separate TCGv temporaries for the shadow registers
This avoids having to manually swap them around when swapping to and

The VMStateDescription version changes, because the meaning of "shadow"
changes in the save file when in PALmode. It would be possible to fix
this, but I don't think it's worth the effort.

If rcu_(un)register_thread() is called together with synchronize_rcu(),
it will wait for the synchronize_rcu() to finish. But when synchronize_rcu()
waits for some events, we can modify the list registry.
We also use the lock rcu_gp_lock to assume that synchronize_rcu() isn't
executed in more than one thread at the same time. Add a new mutex lock
rcu_sync_lock to assume it and rename rcu_gp_lock to rcu_registry_lock.

After commit 626cf8f (icount: set can_do_io outside TB execution,
2014-12-08), can_do_io is set to 1 if not executing code. It is
no longer necessary to make this assumption in cpu_can_do_io.
It is also possible to remove the use_icount test, simply by
never setting cpu->can_do_io to 0 unless use_icount is true.
With these changes cpu_can_do_io boils down to a read of
cpu->can_do_io.

mirror: Fix coroutine reentrance
This fixes a regression introduced by commit dcfb3beb ("mirror: Do zero
write on target if sectors not allocated"), which was reported to cause
aborts with the message "Co-routine re-entered recursively".
The cause for this bug is the following code in mirror_iteration_done():
if (s->common.busy) {
qemu_coroutine_enter(s->common.co, NULL);
}
This has always been ugly because - unlike most places that reenter - it
doesn't have a specific yield that it pairs with, but is more
uncontrolled. What we really mean here is "reenter the coroutine if
it's in one of the four explicit yields in mirror.c".
This used to be equivalent with s->common.busy because neither
mirror_run() nor mirror_iteration() call any function that could yield.
However since commit dcfb3beb this doesn't hold true any more:
bdrv_get_block_status_above() can yield.
So what happens is that bdrv_get_block_status_above() wants to take a
lock that is already held, so it adds itself to the queue of waiting
coroutines and yields. Instead of being woken up by the unlock function,
however, it gets woken up by mirror_iteration_done(), which is obviously
wrong.
In most cases the code actually happens to cope fairly well with such
cases, but in this specific case, the unlock must already have scheduled
the coroutine for wakeup when mirror_iteration_done() reentered it. And
then the coroutine happened to process the scheduled restarts and tried
to reenter itself recursively.
This patch fixes the problem by pairing the reenter in
mirror_iteration_done() with specific yields instead of abusing
s->common.busy.

hw/pci-host/bonito: Avoid buffer overrun for bad LDMA/COP accesses
The LDMA and COP memory regions represent four 32 bit registers
each, but the memory regions themselves are 0x100 bytes large.
Add guards to the read and write accessors so that bogus accesses
beyond the four defined registers don't just run off the end of
the bonldma and boncop structs and into whatever lies beyond.

target-mips: simplify LWL/LDL mask generation
The LWL/LDL instructions mask the GPR with a mask depending on the
address alignement. It is currently computed by doing:
mask = 0x7fffffffffffffffull >> (t1 ^ 63)
It's simpler to generate it by doing:
mask = ~(-1 << t1)
It uses one TCG instruction less, and it avoids a 32/64-bit constant
loading which can take a few instructions on RISC hosts.

pci: allow 0 address for PCI IO/MEM regions
Some kernels program a 0 address for io regions. PCI 3.0 spec

based on patch by Michael Roth <mdroth@linux.vnet.ibm.com>
Add pci_allow_0_addr in MachineClass to conditionally
allow addr 0 for pseries, as this can break other architectures.
This patch allows to hotplug PCI card in pseries machine, as the first
added card BAR0 is always set to 0 address.
This as a temporary hack, waiting to fix PCI memory priorities for more
machine types...

piix: Document coreboot-specific RAM size config register
The existing i440fx initialization code sets a PCI config register that
isn't documented anywhere in the Intel 440FX datasheet. Register 0x57 is
DRAMC (DRAM Control) and has nothing to do with the RAM size.
This was implemented in commit ec5f92ce6ac8ec09056be77e03c941be188648fa
because old coreboot code tried to read registers 0x5a-0x5f,0x56,0x57 to
get the RAM size from QEMU, but I couldn't find out why coreboot did
that. I assume it was a mistake, and the original code was supposed to
be reading the DRB[0-7] registers (offsets 0x60-0x67).
Document that coreboot-specific register offset in a macro and a
comment, for future reference.

commit 27fa7479801ac23609110535a997b2e3ed6eb867

make: load only required dependency files.
The old rules.mak loads dependency .d files using include directive
with file glob pattern "*.d". This breaks the build when build tree has
left-over *.d files from another build.
This patch fixes this by
- loading precise list of .d files made from *.o and *.mo.
- specifying explicit list of required dependency info files for
*.hex autogenerated sources.
Note that Makefile still includes some .d in root directory by including
"*.d".

commit 998b7b1db4f61ee2784d8e9050c3dda15abd4425
Author: Victor Kaplansky <victork@redhat.com>
Date: Sun Aug 9 12:39:53 2015 +0300
make: fix where dependency *.d are stored.
In rules like "bar/%.o: %.c" there is a difference between $(*D) and
$(@D). $(*D) expands to '.', while $(@D) expands to 'bar'. It is
cleaner to generate *.d in the same directory where appropriate *.o
resides. This allows precise including of dependency info from .d files.
As a hack, we also touch two sources for generated *.hex files. Without
this hack, anyone doing "git pull; make" will not get *.hex rebuilt
correctly since the dependency file would be missing.

i.MX: Fix UART driver to work with unitialized "chardev" device
The "chardev" property initialization might have failed (for example because
there are not enough chardevs provided by QEMU).
The serial device emulator needs to be able to work with an uninitialized
(NULL) chardev device pointer.
This patch adds some missing tests on the chr pointer value before
using it.

hw/arm/virt: Wire up secure timer interrupt
Wire up the secure timer interrupt. Since we've defined
that the plain old physical timer is the NS timer, we can
drop the now-out-of-date comment about QEMU not having TZ.
Use a data-driven loop to wire up the timer interrupts, since
we now have four of them and the code is the same for each.

target-arm: Add AArch32 banked register access to secure physical timer
If EL3 is AArch32, then the secure physical timer is accessed via
banking of the registers used for the non-secure physical timer.
Implement this banking.
Note that the access controls for the AArch32 banked registers
remain the same as the physical-timer checks; they are not the
same as the controls on the AArch64 secure timer registers.

target-arm: Add debug check for mismatched cpreg resets
It's easy to accidentally define two cpregs which both try
to reset the same underlying state field (for instance a
clash between an AArch64 EL3 definition and an AArch32
banked register definition). if the two definitions disagree
about the reset value then the result is dependent on which
one happened to be reached last in the hashtable enumeration.
Add a consistency check to detect and assert in these cases:
after reset, we run a second pass where we check that the
reset operation doesn't change the value of the register.

cpu-exec: Do not invalidate original TB in cpu_exec_nocache()
Instead of invalidating an original TB in cpu_exec_nocache()
prematurely, just save a link to it in the temporary generated TB. If
cpu_io_recompile() is raised subsequently from the temporary TB,
invalidate the original one as well. That allows reusing the original TB
each time cpu_exec_nocache() is called to handle expired instruction
counter in icount mode.

block/mirror: limit qiov to IOV_MAX elements
If mirror has more free buffers than IOV_MAX, preadv(2)/pwritev(2)
EINVAL failures may be encountered.
It is possible to trigger this by setting granularity to a low value
like 8192.
This patch stops appending chunks once IOV_MAX is reached.
The spurious EINVAL failure can be reproduced with a qcow2 image file
and the following QMP invocation:
qmp.command('drive-mirror', device='virtio0', target='/tmp/r7.s1',
granularity=8192, sync='full', mode='absolute-paths',
format='raw')
While the guest is running dd if=/dev/zero of=/var/tmp/foo oflag=direct
bs=4k.

block: don't register quorum driver if SHA256 support is unavailable
Commit 488981a4 [block: convert quorum blockdrv to use crypto APIs]
broke qemu-iotest 041 on hosts with GnuTLS < 2.10.0. It converted a
compile-time check to a run-time check at device open time. The result
is that we now advertise a feature (the quorum block driver) that will
never work (on those hosts). There's no way (short of parsing
human-readable error messages) for qemu-iotests or any other API
consumer to recognise that the quorum block driver isn't _actually_
available and shouldn't be used or tested.
Move the run-time check to bdrv_quorum_init() to avoid registering the
quorum block driver if we know it cannot work. This way API consumers
can recognise it's unavailable.

>From the global state section, we don't need runstate with Xen. Right now,
the way the Xen toolstack knows when QEMU is ready is when QEMU reach

The configuration section and the section footers are not going to be
present in previous version of QEMU with xenfv machine, so we skip them.
The Xen toolstack libxenlight does not specify a particular version of the

one would break due to missing "configuration" section and section footers.

migration: Fix global state with Xen.
When doing migration via the QMP command xen_save_devices_state, the
current runstate is not store into the global state section. Also the
current runstate is not the one we want on the receiver side.
During migration, the Xen toolstack paused QEMU before save the devices
state. Also, the toolstack expect QEMU to autostart when the migration is
finished.
So this patch store "running" as it's current runstate.

rtl8139: avoid nested ifs in IP header parsing (CVE-2015-5165)
Transmit offload needs to parse packet headers. If header fields have
unexpected values the offload processing is skipped.
The code currently uses nested ifs because there is relatively little
input validation. The next patches will add missing input validation

tcg/mips: fix add2
The add2 code in the tcg_out_addsub2 function doesn't take into account
the case where rl == al == bl. In that case we can't compute the carry
after the addition. As it corresponds to a multiplication by 2, the
carry bit is the bit 31.
While this is a corner case, this prevents x86-64 guests to boot on a
MIPS host.

macio: re-add TRIM support
Commit bd4214fc dropped TRIM support by mistake. Given it is still

the IDE bus to hang when the host issues a TRIM command.
This patch fixes that by re-adding the TRIM code, ported to the new
new DMA implementation.

AioContext: force event loop iteration using BH
The notify_me optimization introduced in commit eabc97797310
("AioContext: fix broken ctx->dispatching optimization") skips
event_notifier_set() calls when the event loop thread is not blocked in
ppoll(2).
This optimization causes a deadlock if two aio_context_acquire() calls
race. notify_me = 0 during the race so the winning thread can enter
ppoll(2) unaware that the other thread is waiting its turn to acquire
the AioContext.
This patch forces ppoll(2) to return by scheduling a BH instead of
calling aio_notify().
The following deadlock with virtio-blk dataplane is fixed:
qemu ... -object iothread,id=iothread0 \
-drive if=none,id=drive0,file=test.img,... \
-device virtio-blk-pci,iothread=iothread0,drive=drive0
This command-line results in a hang early on without this patch.
Thanks to Paolo Bonzini <pbonzini@redhat.com> for investigating this bug
with me.

hw/net: handle flow control in mcf_fec driver receiver
The network mcf_fec driver emulated receive side method is not dealing
with network queue flow control properly.
Modify the receive side to check if we have enough space in the
descriptors to store the current packet. If not we process none of it
and return 0. When the guest frees up some buffers through its descriptors
we signal the qemu net layer to send more packets.
[Fixed coding style: 4-space indent and curly braces on if statement.

block/ssh: Avoid segfault if inet_connect doesn't set errno.
On some (but not all) systems:
$ qemu-img create -f qcow2 overlay -b ssh://xen/
Segmentation fault
It turns out this happens when inet_connect returns -1 in the
following code, but errno == 0.
s->sock = inet_connect(s->hostport, errp);
if (s->sock < 0) {
ret = -errno;
goto err;
}
In the test case above, no host called "xen" exists, so getaddrinfo fails.
On Fedora 22, getaddrinfo happens to set errno = ENOENT (although it
is *not* documented to do that), so it doesn't segfault.
On RHEL 7, errno is not set by the failing getaddrinfo, so ret =
-errno = 0, so the caller doesn't know there was an error and
continues with a half-initialized BDRVSSHState struct, and everything
goes south from there, eventually resulting in a segfault.
Fix this by setting ret to -EIO (same as block/nbd.c and
block/sheepdog.c). The real error is saved in the Error** errp
struct, so it is printed correctly:
$ ./qemu-img create -f qcow2 overlay -b ssh://xen/
qemu-img: overlay: address resolution failed for xen:22: No address associated with hostname

sheepdog: serialize requests to overwrapping area
Current sheepdog driver only serializes create requests in oid
unit. This mechanism isn't enough for handling requests to
overwrapping area spanning multiple oids, so it can result bugs like
below:
https://bugs.launchpad.net/sheepdog-project/+bug/1456421
This patch adds a new serialization mechanism for the problem. The
difference from the old one is:
1. serialize entire aiocb if their targetting areas overwrap
2. serialize all requests (read, write, and discard), not only creates
This patch also removes the old mechanism because the new one can be
an alternative.

memory: do not add a reference to the owner of aliased regions
Very often the owner of the aliased region is the same as the owner of the alias
region itself. When this happens, the reference count can never go back to 0 and
the owner is leaked. This is for example breaking hot-unplug of virtio-pci
devices (the device cannot be plugged back again with the same id).
Another common use for alias is to transform the system I/O address space
into an MMIO regions; in this case the aliased region never dies, so there
is no problem. Otherwise the owner is always the same for aliasing
and aliased region.
I checked all calls to memory_region_init_alias introduced after commit
dfde4e6 (memory: add ref/unref calls, 2013-05-06) and they do not need the
reference in order to keep the owner of the aliased region alive.

megasas: Add write function to handle write access to PCI BAR 3
This patch fixes a QEMU SEGFAULT when a write operation is performed on
the memory region of the PCI BAR 3 (base address space).
When a writeb(0xe0000000) is performed the .write function is invoked to
handle the write access, however, since the .write is not initialised,
the call to 0, causes QEMU to SEGFAULT.

main-loop: fix qemu_notify_event for aio_notify optimization
aio_notify can be optimized away, and in fact almost always will. However,
qemu_notify_event is used in places where this is incorrect---most notably,
when handling SIGTERM. When aio_notify is optimized away, it is possible that
QEMU enters a blocking ppoll immediately afterwards and stays there, without
reaching main_loop_should_exit().
Fix this by using a bottom half. The bottom half can be optimized too, but
scheduling it is enough for the ppoll not to block. The hang is thus avoided.

block: vpc - prevent overflow if max_table_entries >= 0x40000000
When we allocate the pagetable based on max_table_entries, we multiply
the max table entry value by 4 to accomodate a table of 32-bit integers.
However, max_table_entries is a uint32_t, and the VPC driver accepts
ranges for that entry over 0x40000000. So during this allocation:
s->pagetable = qemu_try_blockalign(bs->file, s->max_table_entries * 4);
The size arg overflows, allocating significantly less memory than
expected.
Since qemu_try_blockalign() size argument is size_t, cast the
multiplication correctly to prevent overflow.
The value of "max_table_entries * 4" is used elsewhere in the code as
well, so store the correct value for use in all those cases.
We also check the Max Tables Entries value, to make sure that it is <
SIZE_MAX / 4, so we know the pagetable size will fit in size_t.

axienet: Flush queued packets when rx is done
eth_can_rx checks s->rxsize and returns false if it is non-zero. Because
of the .can_receive semantics change, this will make the incoming queue
disabled by peer, until it is explicitly flushed. So we should flush it
when s->rxsize is becoming zero.
Squash eth_can_rx semantics into etx_rx and drop .can_receive()
callback, also add flush when rx buffer becomes available again after a
packet gets queued.
The other conditions, "!axienet_rx_resetting(s) &&
axienet_rx_enabled(s)" are OK because enet_write already calls
qemu_flush_queued_packets when the register bits are changed.

hw/net: add simple phy support to mcf_fec driver
The Linux fec driver needs at least basic phy support to probe and work.
The current qemu mcf_fec emulation has no support for the reading or
writing of the MDIO lines to access an attached phy.
This code adds a very simple set of register results for a fixed phy
setup - very similar to that used on an m5208evb board. This is enough
to probe and identify an emulated attached phy.

later discovered & fixed by commit bd09594, thanks to the

detect this directly in the crypto unit tests. Also remove

ide: Check array bounds before writing to io_buffer (CVE-2015-5154)
If the end_transfer_func of a command is called because enough data has
been read or written for the current PIO transfer, and it fails to
correctly call the command completion functions, the DRQ bit in the
status register and s->end_transfer_func may remain set. This allows the
guest to access further bytes in s->io_buffer beyond s->data_end, and
eventually overflowing the io_buffer.
One case where this currently happens is emulation of the ATAPI command
START STOP UNIT.
This patch fixes the problem by adding explicit array bounds checks
before accessing the buffer instead of relying on end_transfer_func to
function correctly.

framebuffer: set DIRTY_MEMORY_VGA on RAM that is used for the framebuffer
The MemoryRegionSection contains enough information to access the
RAM region underlying the framebuffer, and can be cached inside the
display device.
By doing this, the new framebuffer_update_memory_section function can
enable dirty memory logging on the relevant RAM region. The function
must be called whenever the stride or base of the framebuffer changes;
a simple way to cover these cases is to call it on every full frame
invalidation, which is a rare case.
framebuffer_update_display now works entirely on a MemoryRegionSection,
without going through cpu_physical_memory_map/unmap.

memory: count number of active VGA logging clients
For a board that has multiple framebuffer devices, both of them
might want to use DIRTY_MEMORY_VGA on the same memory region.
The lack of reference counting in memory_region_set_log makes
this very awkward to implement.

scsi: Handle no media case for scsi_get_configuration
Currently, scsi_get_configuration always returns a current
profile (DVD or CD), even when there is actually no media present.
By comparison, ide/atapi uses a default profile of 0 (MMC_PROFILE_NONE)
for this case and checks for tray_open, so let's do the same for scsi.
This fixes a problem I'm seeing with Fedora 22 guests where systemd
cdrom_id fails to unmount after a QEMU-initiated eject against a
scsi cdrom device because it believes the media is still present
(but unreadable).

This is a guest-triggerable buffer overflow present in QEMU 2.2.0

caller does not check it.
Luckily, the massive overflow means that QEMU will just SIGSEGV,

qemu-char: Fix missed data on unix socket
Commit 812c1057 introduced HUP detection on unix and tcp sockets prior
to a read in tcp_chr_read. This unfortunately broke CloudStack 4.2
which relied on the old behaviour where data on a socket was readable
even if a HUP was present.
A working solution is to properly check the return values from recv,
handling a closed socket once there is no more data to read.
Also enable polling for G_IO_NVAL to ensure the callback is called
for all possible events as these should now be possible to handle
with the improved error detection.

vfio/pci: Fix RTL8168 NIC quirks
The RTL8168 quirk correctly describes using bit 31 as a signal to
mark a latch/completion, but the code mistakenly uses bit 28. This
causes the Realtek driver to spin on this register for quite a while,
20k cycles on Windows 7 v7.092 driver. Then it gets frustrated and
tries to set the bit itself and spins for another 20k cycles. For
some this still results in a working driver, for others not. About
the only thing the code really does in its current form is protect
the guest from sneaking in writes to the real hardware MSI-X table.
The fix is obviously to use bit 31 as we document that we should.
The other problem doesn't seem to affect current drivers as nobody
seems to use these window registers for writes to the MSI-X table, but
we need to use the stored data when a write is triggered, not the
value of the current write, which only provides the offset.
Note that only the Windows drivers from Realtek seem to use these
registers, the Microsoft drivers provided with Windows 8.1 do not
access them, nor do Linux in-kernel drivers.

AioContext: optimize clearing the EventNotifier
It is pretty rare for aio_notify to actually set the EventNotifier. It
can happen with worker threads such as thread-pool.c's, but otherwise it
should never be set thanks to the ctx->notify_me optimization. The
previous patch, unfortunately, added an unconditional call to
event_notifier_test_and_clear; now add a userspace fast path that
avoids the call.
Note that it is not possible to do the same with event_notifier_set;
it would break, as proved (again) by the included formal model.
This patch survived over 3000 reboots on aarch64 KVM.

AioContext: fix broken placement of event_notifier_test_and_clear
event_notifier_test_and_clear must be called before processing events.
Otherwise, an aio_poll could "eat" the notification before the main
I/O thread invokes ppoll(). The main I/O thread then never wakes up.
This is an example of what could happen:
i/o thread vcpu thread worker thread
---------------------------------------------------------------------
lock_iothread
notify_me = 1
...
unlock_iothread
bh->scheduled = 1
event_notifier_set
lock_iothread
notify_me = 3
ppoll
notify_me = 1
aio_dispatch
aio_bh_poll
thread_pool_completion_bh
bh->scheduled = 1
event_notifier_set
node->io_read(node->opaque)
event_notifier_test_and_clear
ppoll
*** hang ***
"Tracing" with qemu_clock_get_ns shows pretty much the same behavior as
in the previous bug, so there are no new tricks here---just stare more
at the code until it is apparent.
One could also use a formal model, of course. The included one shows
this with three processes: notifier corresponds to a QEMU thread pool
worker, temporary_waiter to a VCPU thread that invokes aio_poll(),
waiter to the main I/O thread. I would be happy to say that the
formal model found the bug for me, but actually I wrote it after the
fact.
This patch is a bit of a big hammer. The next one optimizes it,
with help (this time for real rather than a posteriori :)) from
another, similar formal model.

AioContext: fix broken ctx->dispatching optimization
This patch rewrites the ctx->dispatching optimization, which was the cause
of some mysterious hangs that could be reproduced on aarch64 KVM only.
The hangs were indirectly caused by aio_poll() and in particular by
flash memory updates's call to blk_write(), which invokes aio_poll().
Fun stuff: they had an extremely short race window, so much that
adding all kind of tracing to either the kernel or QEMU made it
go away (a single printf made it half as reproducible).
On the plus side, the failure mode (a hang until the next keypress)
made it very easy to examine the state of the process with a debugger.
And there was a very nice reproducer from Laszlo, which failed pretty
often (more than half of the time) on any version of QEMU with a non-debug
kernel; it also failed fast, while still in the firmware. So, it could
have been worse.
For some unknown reason they happened only with virtio-scsi, but
that's not important. It's more interesting that they disappeared with
io=native, making thread-pool.c a likely suspect for where the bug arose.
thread-pool.c is also one of the few places which use bottom halves
across threads, by the way.
I hope that no other similar bugs exist, but just in case :) I am
going to describe how the successful debugging went... Since the
likely culprit was the ctx->dispatching optimization, which mostly
affects bottom halves, the first observation was that there are two
qemu_bh_schedule() invocations in the thread pool: the one in the aio
worker and the one in thread_pool_completion_bh. The latter always
causes the optimization to trigger, the former may or may not. In
order to restrict the possibilities, I introduced new functions
qemu_bh_schedule_slow() and qemu_bh_schedule_fast():
/* qemu_bh_schedule_slow: */
ctx = bh->ctx;
bh->idle = 0;
if (atomic_xchg(&bh->scheduled, 1) == 0) {
event_notifier_set(&ctx->notifier);
}
/* qemu_bh_schedule_fast: */
ctx = bh->ctx;
bh->idle = 0;
assert(ctx->dispatching);
atomic_xchg(&bh->scheduled, 1);
Notice how the atomic_xchg is still in qemu_bh_schedule_slow(). This
was already debated a few months ago, so I assumed it to be correct.
In retrospect this was a very good idea, as you'll see later.
Changing thread_pool_completion_bh() to qemu_bh_schedule_fast() didn't
trigger the assertion (as expected). Changing the worker's invocation
to qemu_bh_schedule_slow() didn't hide the bug (another assumption
which luckily held). This already limited heavily the amount of
interaction between the threads, hinting that the problematic events
must have triggered around thread_pool_completion_bh().
As mentioned early, invoking a debugger to examine the state of a
hung process was pretty easy; the iothread was always waiting on a
poll(..., -1) system call. Infinite timeouts are much rarer on x86,
and this could be the reason why the bug was never observed there.
With the buggy sequence more or less resolved to an interaction between
thread_pool_completion_bh() and poll(..., -1), my "tracing" strategy was
to just add a few qemu_clock_get_ns(QEMU_CLOCK_REALTIME) calls, hoping
that the ordering of aio_ctx_prepare(), aio_ctx_dispatch, poll() and
qemu_bh_schedule_fast() would provide some hint. The output was:
(gdb) p last_prepare
$3 = 103885451
(gdb) p last_dispatch
$4 = 103876492
(gdb) p last_poll
$5 = 115909333
(gdb) p last_schedule
$6 = 115925212
Notice how the last call to qemu_poll_ns() came after aio_ctx_dispatch().
This makes little sense unless there is an aio_poll() call involved,
and indeed with a slightly different instrumentation you can see that
there is one:
(gdb) p last_prepare
$3 = 107569679
(gdb) p last_dispatch
$4 = 107561600
(gdb) p last_aio_poll
$5 = 110671400
(gdb) p last_schedule
$6 = 110698917
So the scenario becomes clearer:
iothread VCPU thread
--------------------------------------------------------------------------
aio_ctx_prepare
aio_ctx_check
qemu_poll_ns(timeout=-1)
aio_poll
aio_dispatch
thread_pool_completion_bh
qemu_bh_schedule()
At this point bh->scheduled = 1 and the iothread has not been woken up.
The solution must be close, but this alone should not be a problem,
because the bottom half is only rescheduled to account for rare situations
(see commit 3c80ca1, thread-pool: avoid deadlock in nested aio_poll()
calls, 2014-07-15).
Introducing a third thread---a thread pool worker thread, which
also does qemu_bh_schedule()---does bring out the problematic case.
The third thread must be awakened *after* the callback is complete and
thread_pool_completion_bh has redone the whole loop, explaining the
short race window. And then this is what happens:
thread pool worker
--------------------------------------------------------------------------
<I/O completes>
qemu_bh_schedule()
Tada, bh->scheduled is already 1, so qemu_bh_schedule() does nothing
and the iothread is never woken up. This is where the bh->scheduled
optimization comes into play---it is correct, but removing it would
have masked the bug.
So, what is the bug?
Well, the question asked by the ctx->dispatching optimization ("is any
active aio_poll dispatching?") was wrong. The right question to ask
instead is "is any active aio_poll *not* dispatching", i.e. in the prepare
or poll phases? In that case, the aio_poll is sleeping or might go to
sleep anytime soon, and the EventNotifier must be invoked to wake
it up.
In any other case (including if there is *no* active aio_poll at all!)
we can just wait for the next prepare phase to pick up the event (e.g. a
bottom half); the prepare phase will avoid the blocking and service the
bottom half.
Expressing the invariant with a logic formula, the broken one looked like:
!(exists(thread): in_dispatching(thread)) => !optimize
or equivalently:
!(exists(thread):
in_aio_poll(thread) && in_dispatching(thread)) => !optimize
In the correct one, the negation is in a slightly different place:
(exists(thread):
in_aio_poll(thread) && !in_dispatching(thread)) => !optimize
or equivalently:
(exists(thread): in_prepare_or_poll(thread)) => !optimize
Even if the difference boils down to moving an exclamation mark :)
the implementation is quite different. However, I think the new
one is simpler to understand.
In the old implementation, the "exists" was implemented with a boolean
value. This didn't really support well the case of multiple concurrent
event loops, but I thought that this was okay: aio_poll holds the
AioContext lock so there cannot be concurrent aio_poll invocations, and
I was just considering nested event loops. However, aio_poll _could_
indeed be concurrent with the GSource. This is why I came up with the
wrong invariant.
In the new implementation, "exists" is computed simply by counting how many
threads are in the prepare or poll phases. There are some interesting
points to consider, but the gist of the idea remains:
1) AioContext can be used through GSource as well; as mentioned in the
patch, bit 0 of the counter is reserved for the GSource.
2) the counter need not be updated for a non-blocking aio_poll, because
it won't sleep forever anyway. This is just a matter of checking
the "blocking" variable. This requires some changes to the win32
implementation, but is otherwise not too complicated.
3) as mentioned above, the new implementation will not call aio_notify
when there is *no* active aio_poll at all. The tests have to be
adjusted for this change. The calls to aio_notify in async.c are fine;
they only want to kick aio_poll out of a blocking wait, but need not
do anything if aio_poll is not running.
4) nested aio_poll: these just work with the new implementation; when
a nested event loop is invoked, the outer event loop is never in the
prepare or poll phases. The outer event loop thus has already decremented
the counter.

aio-win32: reorganize polling loop
Preparatory bugfixes and tweaks to the loop before the next patch:
- disable dispatch optimization during aio_prepare. This fixes a bug.
- do not modify "blocking" until after the first WaitForMultipleObjects
call. This is needed in the next patch.
- change the loop to do...while. This makes it obvious that the loop
is always entered at least once. In the next patch this is important
because the first iteration undoes the ctx->notify_me increment that
happened before entering the loop.

tests: remove irrelevant assertions from test-aio
In these tests, the purpose of the initial calls to aio_poll and
g_main_context_iteration is simply to put the AioContext in a
known state; the return value of the function does not really
matter. The next patch will change those return values; change
the assertions to a while loop which expresses the intention
better.

Since commit 6e99c63 "net/socket: Drop net_socket_can_send" and friends,
net queues need to be explicitly flushed after qemu_can_send_packet()

This fixes the case of "cont" after "stop" (or migration).

net/vmxnet3: Fix RX TCP/UDP checksum on partially summed packets
Convert partially summed packets to be fully checksummed.
In case csum offloaded packet, vmxnet3 implementation always passes an
RxCompDesc with the "Checksum calculated and found correct" notification
to the OS. This emulates the observed ESXi behavior.
Therefore, if packet has the NEEDS_CSUM bit set, we must calculate and
place a fully computed checksum into the tcp/udp header. Otherwise, the
OS driver will receive a checksum-correct indication but with the actual
tcp/udp checksum field having just the pseudo header csum value.
If host OS performs forwarding, it will forward an incorrectly
checksummed packet.

This patch adds another short PRDT test case where the first sector can

NANOSECONDS_PER_SECOND to NSEC_PER_SEC.
On Mac OS X there is a <dispatch/time.h> system header which also
defines NSEC_PER_SEC. This causes compiler warnings.
Let's use the old name instead. It's longer but it doesn't clash.

virtio-net: Flush incoming queues when DRIVER_OK is being set
This patch fixes network hang after "stop" then "cont", while network
packets keep arriving.
Tested both manually (tap, host pinging guest) and with Jason's qtest
series (plus his "[PATCH 2.4] socket: pass correct size in
net_socket_send()" fix).
As virtio_net_set_status is called when guest driver is setting status
byte and when vm state is changing, it is a good opportunity to flush
queued packets.
This is necessary because during vm stop the backend (e.g. tap) would
stop rx processing after .can_receive returns false, until the queue is
explicitly flushed or purged.
The other interesting condition in .can_receive, virtio_queue_ready(),
is handled by virtio_net_handle_rx() when guest kicks; the 3rd condition
is invalid queue index which doesn't need flushing.

crypto: avoid undefined behavior in nettle calls
Calling a function pointer that was cast from an incompatible function
results in undefined behavior. 'void *' isn't compatible with 'struct
XXX *', so we can't cast to nettle_cipher_func, but have to provide a
wrapper. (Conversion from 'void *' to 'struct XXX *' might require
computation, which won't be done if we drop argument's true type, and
pointers can have different sizes so passing arguments on stack would
bug.)
Having two different prototypes based on nettle version doesn't make
this solution any nicer.

memory: fix refcount leak in memory_region_present
memory_region_present() leaks a reference to a MemoryRegion in the
case "mr == container". While fixing it, avoid reference counting
altogether for memory_region_present(), by using RCU only.
The return value could in principle be already invalid immediately
after memory_region_present returns, but presumably the caller knows
that and it's using memory_region_present to probe for devices that
are unpluggable, or something like that. The RCU critical section
is needed anyway, because it protects as->current_map.

This patch allow to limit number of heads using qxl driver. By default
qxl driver is not limited on any kind on head use so can decide to use

used). This parameter will allow to limit setting a use can do (which
could be confusing).

target-i386: emulate CPUID level of real hardware
W10 insider has a bug where it ignores CPUID level and interprets
CPUID.(EAX=07H, ECX=0H) incorrectly, because CPUID in fact returned
CPUID.(EAX=04H, ECX=0H); this resulted in execution of unsupported
instructions.
While it's a Windows bug, there is no reason to emulate incorrect level.
I used http://instlatx64.atw.hu/ as a source of CPUID and checked that
it matches Penryn Xeon X5472, Westmere Xeon W3520, SandyBridge i5-2540M,
and Haswell i5-4670T.
kvm64 and qemu64 were bumped to 0xD to allow all available features for
them (and to avoid the same Windows bug).

hw/arm/boot: Increase fdt alignment
The Linux kernel on aarch64 creates a page table entry at early bootup
that spans the 2MB range on memory spanning the fdt start address:
[ ALIGN_DOWN(fdt, 2MB) ... ALIGN_DOWN(fdt, 2MB) + 2MB ]
This means that when our current 4k alignment happens to fall at the end
of the aligned region, Linux tries to access memory that is not mapped.
The easy fix is to instead increase the alignment to 2MB, making Linux's
logic always succeed.
We leave the existing 4k alignment for 32bit kernels to not cause any
regressions due to space constraints.

target-arm: Fix broken SCTLR_EL3 reset
The SCTLR_EL3 cpreg definition was implicitly resetting the
register state to 0, which is both wrong and clashes with
the reset done via the SCTLR definition (since sctlr[3]
is unioned with sctlr_s). This went unnoticed until recently,
when an unrelated change (commit a903c449b41f105aa) happened to
perturb the order of enumeration through the cpregs hashtable for
reset such that the erroneous reset happened after the correct one
rather than before it. Fix this by marking SCTLR_EL3 as an alias,
so its reset is left up to the AArch32 view.

target-mips: fix page fault address for LWL/LWR/LDL/LDR
When a LWL, LWR, LDL or LDR instruction triggers a page fault, QEMU
currently reports the aligned address in CP0 BadVAddr, while the Windows
NT kernel expects the unaligned address.
This patch adds a byte access with the unaligned address at the
beginning of the LWL/LWR/LDL/LDR instructions to possibly trigger a page
fault and fill the QEMU TLB.

linux-user: Fix MIPS N64 trap and break instruction bug
For the MIPS N64 ABI when QEMU reads the break/trap instruction so that
it can inspect the break/trap code it reads 8 rather than 4 bytes
which means it finds the code field from the instruction after the
break/trap instruction. This then causes the break/trap handling
code to fail because it does not understand the code number.
The fix forces QEMU to always read 4 bytes of instruction data rather
than deciding how much to read based on the ABI.

doing a savevm, we stored an empty string as state. So when we did a
loadvm, it complained that state was invalid.

block/curl: Don't lose original error when a connection fails.
Currently if qemu is connected to a curl source (eg. web server), and
the web server fails / times out / dies, you always see a bogus EIO
"Input/output error".
For example, choose a large file located on any local webserver which
you control:
$ qemu-img convert -p http://example.com/large.iso /tmp/test
Once it starts copying the file, stop the webserver and you will see
qemu-img fail with:
qemu-img: error while reading sector 61440: Input/output error
This patch does two things: Firstly print the actual error from curl
so it doesn't get lost. Secondly, change EIO to EPROTO. EPROTO is a
POSIX.1 compatible errno which more accurately reflects that there was
a protocol error, rather than some kind of hardware failure.
After this patch is applied, the error changes to:
$ qemu-img convert -p http://example.com/large.iso /tmp/test
qemu-img: curl: transfer closed with 469989 bytes remaining to read
qemu-img: error while reading sector 16384: Protocol error

bdrv_reopen_multiple or bdrv_close; this particular

watchdog/diag288: correctly register for system reset requests
The diag288 watchdog is no sysbus device, therefore it doesn't get

Let's register the reset handler manually, so we get correctly notified
again when a system reset was requested. Also reset the watchdog on
subsystem resets that don't trigger a full system reset.

rbd: make qemu's cache setting override any ceph setting
To be safe, when cache=none is used ceph settings should not be able
to override it to turn on caching. This was previously possible with
rbd_cache=true in the rbd device configuration or a ceph configuration
file. Similarly, rbd settings could have turned off caching when qemu
requested it, although this would just be a performance problem.
Fix this by changing rbd's cache setting to match qemu after all other
ceph settings have been applied.

block: Fix backing file child when modifying graph
This patch moves bdrv_attach_child() from the individual places that add
a backing file to a BDS to bdrv_set_backing_hd(), which is called by all
of them. It also adds bdrv_detach_child() there.
For normal operation (starting with one backing file chain and not
changing it until the topmost image is closed) and live snapshots, this
constitutes no change in behaviour.
For all other cases, this is a fix for the bug that the old backing file
was still referenced as a child, and the new one wasn't referenced.

It is the same as bdrv_open_image(), except that it doesn't only return

As the BdrvChild object already contains a BlockDriverState pointer (and
this is supposed to become the only pointer so that bdrv_append() and
friends can just change a single pointer in BdrvChild), the pbs
parameter is removed for bdrv_open_child().

commit fddd179ab962f6f78a8493742e1068d6a620e059,
"pc: Convert *_MACHINE_OPTIONS macros into functions"
broke the chaining of *_machine_options() functions on
pc-i440fx-2.3, at:
-#define PC_I440FX_2_3_MACHINE_OPTIONS \
- PC_I440FX_2_4_MACHINE_OPTIONS, \
- .alias = NULL, \
- .is_default = 0
+static void pc_i440fx_2_3_machine_options(QEMUMachine *m)
+{
+ pc_i440fx_machine_options(m);
+ m->alias = NULL;
+ m->is_default = 0;
+}
I have replaced PC_I440FX_2_4_MACHINE_OPTIONS with a
pc_i440fx_machine_options() call, instead of calling
pc_i440fx_2_4_machine_options(). This broke the setting of default_machine_opts
and default_display on pc-i440fx-{2.0,2,1,2.2,2.3}.
Fix this by making pc_i440fx_2_3_machine_options() reuse
pc_i440fx_2_4_machine_options().

Revert "virtio-net: enable virtio 1.0"
This reverts commit df91055db5c9cee93d70ca8c08d72119a240b987.
This is because:
- vhost support virtio 1.0 now
- transport code (e.g virtio-pci) set this feature when modern is
enabled, setting this unconditionally will break disable-modern=on.

tci: Fix compile failure by including qemu-common.h
Compilation of TCI was accidentally broken by the recent disassembler
changes:
CC x86_64-softmmu/arch_init.o
In file included from target-i386/cpu-qom.h:23:0,
from target-i386/cpu.h:986,
from include/qemu-common.h:122,
from include/disas/bfd.h:12,
from disas/tci.c:20:
include/qom/cpu.h:178:43: error: unknown type name ‘disassemble_info’
void (*disas_set_info)(CPUState *cpu, disassemble_info *info);
^
include/qom/cpu.h:179:1: error:
no semicolon at end of struct or union [-Werror]
} CPUClass;
^
cc1: all warnings being treated as errors
The underlying cause of this is an include loop:
bfd.h -> qemu-common.h -> target-arm/cpu.h -> target-arm/cpu-qom.h
-> qom/cpu.h -> bfd.h
which means that if bfd.h is included first then qom/cpu.h doesn't
get the definition of the disassemble_info type that it wanted.
The easiest fix for this is to include qemu-common.h from tci.c
before including disas/bfd.h.

disas: cris: Fix 0 buffer length case
Cris has the complication of variable length instructions and has
a check in place to clamp memory reads in case the disas request
doesn't have enough bytes for the instruction being disas'd. This
breaks down in the case where disassembling for the monitor where
the buffer length is defaulted to 0.
The buffer length should never be zero for a regular target_disas,
so we can safely assume the 0 case is for the monitor in which case
consider the buffer length to be the max for cris instructions.

Move the target_disas() ARM specifics to the QOM disas_set_info hook

cpu: Convert cpu_index into a bitmap
Currently CPUState::cpu_index is monotonically increasing and a newly
created CPU always gets the next higher index. The next available
index is calculated by counting the existing number of CPUs. This is
fine as long as we only add CPUs, but there are architectures which
are starting to support CPU removal, too. For an architecture like PowerPC
which derives its CPU identifier (device tree ID) from cpu_index, the
existing logic of generating cpu_index values causes problems.
With the currently proposed method of handling vCPU removal by parking
the vCPU fd in QEMU
(Ref: http://lists.gnu.org/archive/html/qemu-devel/2015-02/msg02604.html),
generating cpu_index this way will not work for PowerPC.
This patch changes the way cpu_index is handed out by maintaining
a bit map of the CPUs that tracks both addition and removal of CPUs.
The CPU bitmap allocation logic is part of cpu_exec_init(), which is
called by instance_init routines of various CPU targets. Newly added
cpu_exec_exit() API handles the deallocation part and this routine is

Note: This new CPU enumeration is for !CONFIG_USER_ONLY only.
CONFIG_USER_ONLY continues to have the old enumeration logic.

cpu: Add Error argument to cpu_exec_init()
Add an Error argument to cpu_exec_init() to let users collect the
error. This is in preparation to change the CPU enumeration logic
in cpu_exec_init(). With the new enumeration logic, cpu_exec_init()
can fail if cpu_index values corresponding to max_cpus have already
been handed out.
Since all current callers of cpu_exec_init() are from instance_init,
use error_abort Error argument to abort in case of an error.

cpu: Reorder cpu->as, cpu->thread_id, cpu->memory_dispatch init
Instead of initializing cpu->as, cpu->thread_id, and reloading memory
map while holding cpu_list_lock(), do it earlier, before locking the CPU
list and initializing cpu_index.
This allows the code handling cpu_index and global CPU list to be
isolated from the rest.

mips/kvm: Sync with newer MIPS KVM headers
The KVM_REG_MIPS_COUNT_* definitions are now included in
linux-headers/asm-mips/kvm.h since commit b061808d39fa ("linux-headers:
update linux headers to kvm/next"), therefore the duplicate definitions
in target-mips/kvm.c can now be dropped (the definitions were tweaked
slightly in commit 7a52ce8a1607 ("linux-headers: update") which
triggered the following build warnings turned errors):
target-mips/kvm.c:232:0: error: "KVM_REG_MIPS_COUNT_CTL" redefined [-Werror]
linux-headers/asm/kvm.h:129:0: note: this is the location of the previous definition

Also update the MIPS_C0_{32,64} macros to utilise definitions more

tcg/mips: Fix build error from merged memop+mmu_idx parameter
Commit 3972ef6f830d ("tcg: Push merged memop+mmu_idx parameter to
softmmu routines") caused the following build errors when building TCG
for MIPS:
In file included from tcg/tcg.c:258:0:
tcg/mips/tcg-target.c In function ‘tcg_out_qemu_ld_slow_path’:
tcg/mips/tcg-target.c:1015:22: error: ‘lb’ undeclared (first use in this function)

tcg/mips/tcg-target.c:1058:22: error: ‘lb’ undeclared (first use in this function)
It looks like lb was meant to refer to the TCGLabelQemuLdst *l
parameter, so fix both references to lb to refer to just l.

hw/i386/pc: don't carry FDC from pc_basic_device_init() to pc_cmos_init()
Thanks to the last patch, pc_cmos_init() doesn't need the (optional)
board-default FDC any longer as an input parameter. Update
pc_basic_device_init() not to hand it back to pc_init1() / pc_q35_init(),
and update the latter not to carry the FDC to pc_cmos_init(). This
simplifies the code.
pc_init1() | pc_q35_init()

hw/i386/pc: reflect any FDC @ ioport 0x3f0 in the CMOS
With the pc-q35-2.4 machine type, if the user creates an ISA FDC manually:
-device isa-fdc,driveA=drive-fdc0-0-0 \
-drive file=...,if=none,id=drive-fdc0-0-0,format=raw
then the board-default FDC will be skipped, and only the explicitly
requested FDC will exist. qtree-wise, this is correct; however such an FDC
is currently not registered in the CMOS, because that code is only reached
for the board-default FDC.
The pc_cmos_init_late() one-shot reset handler -- one-shot because the
CMOS is not reprogrammed during warm reset -- should search for any ISA
FDC devices, created implicitly (by board code) or explicitly, and set the
CMOS accordingly to the ISA FDC(s) with iobase=0x3f0:
- if there is no such FDC, report both drives absent,
- if there is exactly one such FDC, report its drives in the CMOS,
- if there are more than one such FDCs, then pick one (it is not specified
which one), and print a warning about the ambiguity.

ich9: implement strap SPKR pin logic
If the signal is sampled high, this indicates that the system is
strapped to the "No Reboot" mode (ICH9 will disable the TCO Timer system
reboot feature). The status of this strap is readable via the NO_REBOOT
bit (CC: offset 0x3410:bit 5).
The NO_REBOOT bit is set when SPKR pin on ICH9 is sampled high. This bit
may be set or cleared by software if the strap is sampled low but may
not override the strap when it indicates "No Reboot".
This patch implements the logic where hardware has ability to set SPKR
pin through a property named "noreboot" and it's sampled high by
default.

qga: added GuestPCIAddress information
PCIAddress inforfation is obtained via SetupApi, which provides the
information about address, bus, etc. We look throught entire device tree
in the system and try to find device object for given volume. For this PDO
SetupDiGetDeviceRegistryProperty is called, which reads PCI configuration
for a given devicei if it is possible.
This is the most convinient way for a userspace service. The lookup is
performed for every volume available. However, this information is
not mandatory for vss-provider.
In order to use SetupApi we need to notify linker about it. We do not need
to install additional libs, so we do not make separate configuration
option to use libsetupapi.su
SetupApi gives as the same information as kernel driver
with IRP_MN_QUERY_INTERFACE.

https://technet.microsoft.com/en-us/library/ee851589(v=ws.10).aspx
Bus type could be obtained using IOCTL_STORAGE_QUERY_PROPERTY. Enum
STORAGE_BUS_TYPE describes all buses supported by OS.
Windows defines more bus types than Linux. Thus some values have been added
to GuestDiskBusType.

qga: added mountpoint and filesystem type for single volume
We should use GetVolumeXXX api to work with volumes. This will help us to
resolve the situation with volumes without drive letter, i.e. when the
volume is mounted as a folder. Such volume is called mounted folder.
This volume is a regular mounted volume from all other points of view.
The information about non mounted volume is reported as System Reserved.
This volume is not mounted and thus it is not writable.
GuestDiskAddressList API is not used because operations are performed with
volumes but no with disks. This means that spanned disk will
be counted and handled as a single volume. It is worth mentioning
that the information about every disk in the volume can be queried
via IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS.

qga: win32 qmp_guest_network_get_interfaces implementation
By default, IPv4 prefixes will be derived by matching the address
to those returned by GetAdaptersInfo. IPv6 prefixes can not be
matched this way due to the unpredictable order of entries.
In Windows Vista/2008 guests and newer, both IPv4 and IPv6 prefixes
can be retrieved from OnLinkPrefixLength. Setting --extra-cflags
in the build configuration to "-D_WIN32_WINNT=0x600"
or greater makes OnLinkPrefixLength available. Setting --extra-cflags
is not required and if not set, the default approach to get the prefix
will be taken.

qga/qmp_guest_fstrim: Return per path fstrim result
The current guest-fstrim support only returns an error if some
mountpoint was unable to be trimmed, skipping any possible additional
mountpoints. The result of the TRIM operation itself is also discarded.
This change returns a per mountpoint result of the TRIM operation. If an
error occurs on some mountpoints that error is returned and the
guest-fstrim continue with any additional mountpoints.
The returned values for errors, minimum and trimmed are dependant on the
filesystem, storage stacks and kernel version.

qga/commands-posix: Fix bug in guest-fstrim
The FITRIM ioctl updates the fstrim_range structure it receives. This
way the caller can determine how many bytes were trimmed. The
guest-fstrim logic reuses the same fstrim_range for each filesystem,
effectively limiting each filesystem to trim at most as much as the
previous was able to trim.
If a previous filesystem would have trimmed 0 bytes, than the next
filesystem would report an error 'Invalid argument' because a FITRIM
request with length 0 is not valid.
This change resets the fstrim_range structure for each filesystem.

to not get the -2^31 case wrong. Finally don't initialize shift to 4,
it's already done in the for loop.

sPAPR: Clear stale MSIx table during EEH reset
The PCI device MSIx table is cleaned out in hardware after EEH PE
reset. However, we still hold the stale MSIx entries in QEMU, which
should be cleared accordingly. Otherwise, we will run into another
(recursive) EEH error and the PCI devices contained in the PE have
to be offlined exceptionally.
The patch introduces function spapr_phb_vfio_eeh_pre_reset(), which
is called by sPAPR when asserting hot or fundamental reset, to clear
stale MSIx table for VFIO PCI devices before EEH PE reset so that
MSIx table could be restored properly after EEH PE reset.

spapr_vty: lookup should only return valid VTY objects
If a guest passes the reg property of a valid VIO object that is not a VTY
to either H_GET_TERM_CHAR or H_PUT_TERM_CHAR, QEMU hits a dynamic cast
assertion and aborts.
PAPR+ says "Hypervisor checks the termno parameter for validity against the
Vterm IOA unit addresses assigned to the partition, else return H_Parameter."
This patch adds a type check to ensure vty_lookup() either returns a pointer
to a valid VTY object or NULL. H_GET_TERM_CHAR and H_PUT_TERM_CHAR will
now return H_PARAMETER to the guest instead of crashing.
The patch has no effect on the reg == 0 hack used to implement the RTAS call
display-character.

xics_kvm: Don't enable KVM_CAP_IRQ_XICS if already enabled
When supporting CPU hot removal by parking the vCPU fd and reusing
it during hotplug again, there can be cases where we try to reenable
KVM_CAP_IRQ_XICS CAP for the vCPU for which it was already enabled.
Introduce a boolean member in ICPState to track this and don't
reenable the CAP if it was already enabled earlier.
Re-enabling this CAP should ideally work, but currently it results in
kernel trying to create and associate ICP with this vCPU and that
fails since there is already an ICP associated with it. Hence this
patch is needed to work around this problem in the kernel.
This change allows CPU hot removal to work for sPAPR.

Now that we have the generic MachineState, fold sPAPREnvironment into

1 * 8 / 9 = 0

Number of servers needs to be greater 0

... and in-kernel XICS:

With this patch, we are sure that nr_servers > 0. Passing the same bogus

target-ppc: fix hugepage support when using memory-backend-file
Current PPC code relies on -mem-path being used in order for
hugepage support to be detected. With the introduction of
MemoryBackendFile we can now handle this via:
-object memory-file-backend,mem-path=...,id=hugemem0 \
-numa node,id=mem0,memdev=hugemem0
Management tools like libvirt treat the 2 approaches as
interchangeable in some cases, which can lead to user-visible
regressions even for previously supported guest configurations.
Fix these by also iterating through any configured memory

macio: remove nonexistent interrupt on pin 1
The current macio implementation declares an interrupt that doesn't appear to
exist in the hardware or any other emulator implementation. OpenBIOS detects
this interrupt and generates an 'interrupts' property in the macio device tree
entry. Mac OS 9 halts boot when it detects this interrupt, so it has been
removed to permit further progress in the boot process.

target-i386: avoid overflow in the tsc-frequency property
The TSC frequency fits comfortably in an int when expressed in kHz,
but it may overflow when converted to Hz. In this case,
tsc-frequency returns a negative value because x86_cpuid_get_tsc_freq
does a 32-bit multiplication before assigning to int64_t.
For simplicity just make tsc_khz a 64-bit value.

block/raw-posix: Don't think /dev/fd/<NN> is a floppy drive.
In libguestfs we use /dev/fd/<NN> to pass pre-opened file descriptors
to qemu-img. Lately I've discovered that although this works, qemu
believes that these are floppy disk images. That in itself isn't much
of a problem, but now qemu prints a warning about host floppy
pass-thru being deprecated.
Extend the existing test so that it ignores /dev/fd/ as well as
/dev/fdset/
A simple test of this, if you are using the bash shell, is:
qemu-img info <( cat /dev/null )
without this patch:
$ qemu-img info <( cat /dev/null )
qemu-img: Host floppy pass-through is deprecated
Support for it will be removed in a future release.

migration: create new section to store global state
This includes a new section that for now just stores the current qemu state.
Right now, there are only one way to control what is the state of the
target after migration.
- If you run the target qemu with -S, it would start stopped.
- If you run the target qemu without -S, it would run just after migration finishes.
The problem here is what happens if we start the target without -S and
there happens one error during migration that puts current state as
-EIO. Migration would ends (notice that the error happend doing block
IO, network IO, i.e. nothing related with migration), and when
migration finish, we would just "continue" running on destination,
probably hanging the guest/corruption data, whatever.

Fail more cleanly in mismatched RAM cases

destination, QEMU would hang waiting for a disconnect on the source
and wouldn't release from that hang until the destination was manually
killed.
Mark the stream as being in error, this causes the destination to die
and the source to carry on.

Sort destination RAMBlocks to be the same as the source
Use the order of incoming RAMBlocks from the source to record
an index number; that then allows us to sort the destination
local RAMBlock list to match the source.
Now that the RAMBlocks are known to be in the same order, this
simplifies the RDMA Registration step which previously tried to
match RAMBlocks based on offset (which isn't guaranteed to match).
Looking at the existing compress code, I think it was erroneously
relying on an assumption of matching ordering, which this fixes.

Translate offsets to destination address space
The 'offset' field in RDMACompress and 'current_addr' field
in RDMARegister are commented as being offsets within a particular
RAMBlock, however they appear to actually be offsets within the
ram_addr_t space.
The code currently assumes that the offsets on the source/destination
match, this change removes the need for the assumption for these
structures by translating the addresses into the ram_addr_t space of
the destination host.
Note: An alternative would be to change the fields to actually
take the data they're commented for; this would potentially be
simpler but would break stream compatibility for those cases
that currently work.

Only try and read a VMDescription if it should be there
The VMDescription section maybe after the EOF mark, the current code
does a 'qemu_get_byte' and either gets the header byte identifying the
description or an error (which it ignores). Doing the 'get' upsets
RDMA which hangs on old machine types without the VMDescription.
Just avoid reading the VMDescription if we wouldn't send it.

rocker: mark copy-to-cpu pkts as forwarding offloaded
For pkts copied to the CPU (to be processed by guest driver), mark the Rx
descriptor with flag "OFFLOAD_FWD" to indicate device has already forwarded
pkt. The guest driver will use this indicator to avoid duplicate
forwarding in the guest OS.
Examples include bcast/mcast/unknown ucast pkts flooded to bridged ports.
We want to avoid both the device and the guest bridge driver flooding these
pkts, which would result in duplicates pkts on the wire. Packet sampling,
such as sFlow, can also use this technique to mark pkts for the guest OS to
record but otherwise drop.

rocker: don't queue receive pkts when port is disabled
Commit 6e99c63 ("net/socket: Drop net_socket_can_send") changed the
semantics around .can_receive for sockets to now require the device to
flush queued pkts when transitioning to a .can_receive=true state. Rocker
device was not flushing the queue on .can_receive=true transition, so the
receiver was stuck.
But, turns out we really don't want any queuing at all on the port when the
port is disabled, otherwise when the port transitions to enabled, we'd
receive and forward stale pkts that really should have been dropped. So,
let's remove .can_receive so avoid queuing and drop the pkt in .receive if
the port is disabled.

vmxnet3: Fix incorrect small packet padding
When running ESXi under qemu there is an issue with the ESXi guest
discarding packets that are too short. The guest discards any packets
under the normal minimum length for an ethernet packet (60). This
results in odd behaviour where other hosts or VMs on other hosts can
communicate with the ESXi guest just fine (since there's a physical NIC
somewhere doing padding), but VMs on the host and the host itself cannot
because the ARP request packets are too small for the ESXi host to
accept.
Someone in the past thought this was worth fixing, and added code to the
vmxnet3 qemu emulation such that if it is receiving packets smaller than
60 bytes to pad the packet out to 60. Unfortunately this code is wrong
(or at least in the wrong place). It does so BEFORE before taking into
account the vnet_hdr at the front of the packet added by the tap device.
As a result, it might add padding, but it never adds enough.
Specifically it adds 10 less (the length of the vnet_hdr) than it needs
to.
The following (hopefully "obviously correct") patch simply swaps the
order of processing the vnet header and the padding. With this patch an
ESXi guest is able to communicate with the host or other local VMs.

e1000: flush packets when link comes up
e1000_can_receive() checks the link up status register bit. If the bit

avoid wasting CPU reading packets that cannot be delivered. The queue
must be flushed once the link comes back up again.
This patch fixes broken e1000 receive with Mac OS X Snow Leopard guests
and tap networking. Flushing the queue invokes the async send callback,
which re-enables tap fd read.

ich9: add TCO interface emulation
This interface provides some registers within a 32-byte range and can be
acessed through PCI-to-LPC bridge interface (PMBASE + 0x60).
It's commonly used as a watchdog timer to detect system lockups through
SMIs that are generated -- if TCO_EN bit is set -- on every timeout. If
NO_REBOOT bit is not set in GCS (General Control and Status register),
the system will be resetted upon second timeout if TCO_RLD register
wasn't previously written to prevent timeout.
This patch adds support to TCO watchdog logic and few other features
like mapping NMIs to SMIs (NMI2SMI_EN bit), system intruder detection,
etc. are not implemented yet.

crypto: introduce new module for computing hash digests
Introduce a new crypto/ directory that will (eventually) contain
all the cryptographic related code. This initially defines a
wrapper for initializing gnutls and for computing hashes with
gnutls. The former ensures that gnutls is guaranteed to be
initialized exactly once in QEMU regardless of CLI args. The
block quorum code currently fails to initialize gnutls so it
only works by luck, if VNC server TLS is not requested. The
hash APIs avoids the need to litter the rest of the code with
preprocessor checks and simplifies callers by allocating the
correct amount of memory for the requested hash.

block: update bdrv_drain_all()/bdrv_drain() comments
The doc comments for bdrv_drain_all() and bdrv_drain() are outdated:
* The bdrv_drain() comment is a poor man's bdrv_lock()/bdrv_unlock()
which Fam Zheng is currently developing. Unfortunately this warning
was never really enough because devices keep submitting I/O and op
blockers don't prevent that.
* The bdrv_drain_all() comment is still partially correct but reflects
the nature of the implementation rather than API documentation.
Do make it clear that bdrv_drain() is only appropriate within an
AioContext. For anything spanning AioContexts you need
bdrv_drain_all().

vl: move rom_load_all after machine init done
On ARM, commit ac9d32e39664e060cd1b538ff190980d57ad69e4 postponed the
memory preparation for boot until the machine init done notifier. This
has for consequence to insert ROM at machine init done time.
However the rom_load_all function stayed called before the ROM are
inserted. As a consequence the rom_load_all function does not do
everything it is expected to do, on ARM.
It currently registers the ROM reset notifier but does not iterate through
the registered ROM list. the isrom field is not set properly. This latter
is used to report info in the monitor and also to decide whether the
rom->data can be freed on ROM reset notifier.
To fix that regression the patch moves the rom_load_all call after
machine init done. We also take the opportunity to rename the rom_load_all
function into rom_check_and_resgister_reset() and integrate the
rom_load_done in it.

vfio/pci : Add pba_offset PCI quirk for Chelsio T5 devices
Fix pba_offset initialization value for Chelsio T5 Virtual Function
device. The T5 hardware has a bug in it where it reports a Pending Interrupt
Bit Array Offset of 0x8000 for its SR-IOV Virtual Functions instead
of the 0x1000 that the hardware actually uses internally. As the hardware
doesn't return the correct pba_offset value, add a quirk to instead
return a hardcoded value of 0x1000 when a Chelsio T5 VF device is
detected.
This bug has been fixed in the Chelsio's next chip series T6 but there are
no plans to respin the T5 ASIC for this bug. It is just documented in the
T5 Errata and left it at that.

PCI bus calls vfio_listener_region_add() for every DMA window. This
installs a notifier for IOMMU memory regions. The notifier is supposed
to be removed vfio_listener_region_del(), however in the case of mixed
PHB (emulated + VFIO devices) when last VFIO device is unplugged and
container gets destroyed, all existing DMA windows stay alive altogether
with the notifiers which are on the linked list which head was in
the destroyed container.
This unregisters IOMMU memory region notifier when a container is
destroyed.

hw/vfio/platform: add irqfd support
This patch aims at optimizing IRQ handling using irqfd framework.
Instead of handling the eventfds on user-side they are handled on
kernel side using
- the KVM irqfd framework,
- the VFIO driver virqfd framework.
the virtual IRQ completion is trapped at interrupt controller
This removes the need for fast/slow path swap.
Overall this brings significant performance improvements.

cpu-all: complete "real" host page size API
Currently the "host" page size alignment API is really aligning to both
host and target page sizes. There is the qemu_real_page_size which can
be used for the actual host page size but it's missing a mask and ALIGN
macro as provided for qemu_page_size. Complete the API. This allows
system level code that cares about the host page size to use a
consistent alignment interface without having to un-needingly align to
the target page size. This also reduces system level code dependency
on the cpu specific TARGET_PAGE_SIZE.

These commands are handled entirely by QEMU. Do not raise an SMI

startup) the firmware might not have installed an SMI handler.
When this happens (e.g. the kernel supports SMIs, or you are using

where there is no code to execute.

exec: skip MMIO regions correctly in cpu_physical_memory_write_rom_internal
Loading the BIOS in the mac99 machine is interesting, because there is a
PROM in the middle of the BIOS region (from 16K to 32K). Before memory
region accesses were clamped, when QEMU was asked to load a BIOS from
0xfff00000 to 0xffffffff it would put even those 16K from the BIOS file
into the region. This is weird because those 16K were not actually
visible between 0xfff04000 and 0xfff07fff. However, it worked.
After clamping was added, this also worked. In this case, the
cpu_physical_memory_write_rom_internal function split the write in
three parts: the first 16K were copied, the PROM area (second 16K) were
ignored, then the rest was copied.
Problems then started with commit 965eb2f (exec: do not clamp accesses
to MMIO regions, 2015-06-17). Clamping accesses is not done for MMIO
regions because they can overlap wildly, and MMIO registers can be
expected to perform full-width accesses based only on their address
(with no respect for adjacent registers that could decode to completely
different MemoryRegions). However, this lack of clamping also applied
to the PROM area! cpu_physical_memory_write_rom_internal thus failed
to copy the third range above, i.e. only copied the first 16K of the BIOS.
In effect, address_space_translate is expecting _something else_ to do
the clamping for MMIO regions if the incoming length is large. This
"something else" is memory_access_size in the case of address_space_rw,
so use the same logic in cpu_physical_memory_write_rom_internal.

Stop including qemu-common.h in memory.h
Including qemu-common.h from other header files is generally a bad
idea, because it means it's very easy to end up with a circular
dependency. For instance, if we wanted to include memory.h from
qom/cpu.h we'd end up with this loop:
memory.h -> qemu-common.h -> cpu.h -> cpu-qom.h -> qom/cpu.h -> memory.h
Remove the include from memory.h. This requires us to fix up a few
other files which were inadvertently getting declarations indirectly
through memory.h.
The biggest change is splitting the fprintf_function typedef out
into its own header so other headers can get at it without having
to include qemu-common.h.

hw/intc/arm_gic_common.c: Reset all registers
The arm_gic_common reset function was missing reset code for
several of the GIC's state fields:
* bpr[]
* abpr[]
* priority1[]
* priority2[]
* sgi_pending[]
* irq_target[] (SMP configurations only)
These probably went unnoticed because most guests will either
never touch them, or will write to them in the process of
configuring the GIC before enabling interrupts.

target-arm: Split DISAS_YIELD from DISAS_WFE
Currently we use DISAS_WFE for both WFE and YIELD instructions.
This is functionally correct because at the moment both of them
are implemented as "yield this CPU back to the top level loop so
another CPU has a chance to run". However it's rather confusing
that YIELD ends up calling HELPER(wfe), and if we ever want to
implement real behaviour for WFE and SEV it's likely to trip us up.
Split out the yield codepath to use DISAS_YIELD and a new
HELPER(yield) function, and have HELPER(wfe) call HELPER(yield).

ahci: fix sdb fis semantics
There are two things to fix here:
The first one is subtle: the PxSACT register in the AHCI HBA has different
semantics from the field it is shadowing, the ACT field in the
Set Device Bits FIS.
In the HBA register, PxSACT acts as a bitfield indicating outstanding
NCQ commands where a set bit indicates a pending NCQ operation. The FIS
field however operates as an RWC register update to PxSACT, where a set
bit indicates a *successfully* completed command.
Correct the FIS semantics. At the same time, move the "clear finished"
action to the SDB FIS generation instead of the register read to mimick
how the other shadow registers work, which always just report the last
reported value from a FIS, and not the most current values which may
not have been reported by a FIS yet.
Lastly and more simply, SATA 3.2 section 13.6.4.2 (and later sections)
all specify that the Interrupt bit for the SDB FIS should always be set
to one for NCQ commands. That's currently the only time we generate this
FIS, so set it on all the time.

ahci: Do not map cmd_fis to generate response
The Register D2H FIS should copy the current values of
the registers instead of just parroting back the same
values the guest sent back to it.
In this case, the SECTOR COUNT variables are actually
not generally meaningful in terms of standard commands
(See ATA8-AC3 Section 9.2 Normal Outputs), so it actually
probably doesn't matter what we put in here.
Meanwhile, we do need to use the Register update FIS from
the NCQ pathways (in error cases), so getting rid of
references to cur_cmd here is a win for AHCI concurrency.

ahci: add get_cmd_header helper
cur_cmd is an internal bookmark that points to the
current AHCI Command Header being processed by the
AHCI state machine. With NCQ needing to occasionally
rely on some of the same AHCI helpers, we cannot use
cur_cmd and will need to grab explicit pointers instead.
In an attempt to begin relying on the cur_cmd pointer
less, add a helper to let us specifically get the pointer
to the command header of particular interest.

ahci: correct ncq sector count
uint16_t isn't enough to hold the real sector count, since a value of
zero implies a full 64K sectors, so we need a uint32_t here.
We *could* cheat and pretend that this value is 0-based and fit it in
a uint16_t, but I'd rather waste 2 bytes instead of a future dev's
10 minutes when they forget to +1/-1 accordingly somewhere.

ide: add limit to .prepare_buf()
prepare_buf should not always grab as many descriptors
as it can, sometimes it should self-limit.
For example, an NCQ transfer of 1 sector with a PRDT that
describes 4GiB of data should not copy 4GiB of data, it
should just transfer that first 512 bytes.
PIO is not affected, because the dma_buf_rw dma helpers
already have a byte limit built-in to them, but DMA/NCQ
will exhaust the entire list regardless of requested size.
AHCI 1.3 specifies in section 6.1.6 Command List Underflow that
NCQ is not required to detect underflow conditions. Non-NCQ
pathways signal underflow by writing to the PRDBC field, which
will already occur by writing the actual transferred byte count
to the PRDBC, signaling the underflow.
Our NCQ pathways aren't required to detect underflow, but since our DMA
backend uses the size of the PRDT to determine the size of the transer,
if our PRDT is bigger than the transaction (the underflow condition) it
doesn't cost us anything to detect it and truncate the PRDT.
This is a recoverable error and is not signaled to the guest, in either
NCQ or normal DMA cases.
For BMDMA, the existing pathways should see no guest-visible difference,
but any bytes described in the overage will no longer be transferred
before indicating to the guest that there was an underflow.

There's a handful of trivial bugs in the libqos/ahci functions,
squish them together.
- Zero cached pointers after freeing them
- The Command List Buffer is an array of 32x 32 byte structures, not
32x 8 byte pointers -- it's 1MiB, not 256 bytes. Zero it ALL.

ahci: Do not ignore memory access read size
The only guidance the AHCI specification gives on memory access is:
"Register accesses shall have a maximum size of 64-bits; 64-bit access
must not cross an 8-byte alignment boundary."
I interpret this to mean that aligned or unaligned 1, 2 and 4 byte
accesses should work, as well as aligned 8 byte accesses.
In practice, a real Q35/ICH9 responds to 1, 2, 4 and 8 byte reads
regardless of alignment. Windows 7 can be observed making 1 byte
reads to the middle of 32 bit registers to fetch error codes.
Introduce a wrapper to support unaligned accesses to AHCI.
This wrapper will support aligned 8 byte reads, but will make
no effort to support unaligned 8 byte reads, which although they
will work on real hardware, are not guaranteed to work and do
not appear to be used by either Windows or Linux.

s390x/migration: Introduce 2.4 machine
The section footer changes commit f68945d42bab ("Add a protective
section footer") and commit 37fb569c0198 ("Disable section footers
on older machine types") broke migration for any non-versioned
machines.
This pinpoints a problem of s390-ccw machines: it needs to
be versioned to be compatible with future changes in common
code data structures such as section footers.
Let's introduce a version scheme for s390-ccw-virtio machines.
We will use the old s390-ccw-virtio name as alias to the latest
version as all existing libvirt XML for the ccw type were expanded
by libvirt to that name.
The only downside of this patch is, that the old alias s390-ccw
will no longer be available as machines can have only one alias,
but it should not really matter.

s390x/gdb: synchronize cpu state after modifying acrs
Whenever we touch the access control registers, we have to make sure that
the values will make it into kvm. Otherwise the change will simply be lost.
When synchronizing qemu and kvm, a normal KVM_PUT_RUNTIME_STATE does not take
care of these registers. Let's simply trigger a KVM_PUT_FULL_STATE sync,
so the values will directly be written to kvm. The performance overhead can
be ignored and this is much cleaner than manually writing these registers to kvm
via our two supported ways.

s390x/ipl: Fix boot if no bootindex was specified
commit fa92e218df1d ("s390x/ipl: avoid sign extension") introduced
a regression:
qemu-system-s390x -drive file=image.qcow,format=qcow2
does not boot, the bios states
"No virtio-blk device found!"
adding bootindex=1 does boot.
The reason is that the uint32_t as return value will not do the right
thing for the return -1 (default without bootindex).
The bios itself, will interpret a 64bit -1 as autodetect (but it will
interpret 32bit -1 as ccw device address ff.ff.ffff)

block: Fix dirty bitmap in bdrv_co_discard
Unsetting dirty globally with discard is not very correct. The discard may zero
out sectors (depending on can_write_zeroes_with_unmap), we should replicate
this change to destination side to make sure that the guest sees the same data.
Calling bdrv_reset_dirty also troubles mirror job because the hbitmap iterator
doesn't expect unsetting of bits after current position.
So let's do it the opposite way which fixes both problems: set the dirty bits
if we are to discard it.

block/iscsi: add support for request timeouts
libiscsi starting with 1.15 will properly support timeout of iscsi
commands. The default will remain no timeout, but this can
be changed via cmdline parameters, e.g.:
qemu -iscsi timeout=30 -drive file=iscsi://...
If a timeout occurs a reconnect is scheduled and the timed out command
will be requeued for processing after a successful reconnect.
The required API call iscsi_set_timeout is present since libiscsi
1.10 which was released in October 2013. However, due to some bugs
in the libiscsi code the use is not recommended before version 1.15.
Please note that this patch bumps the libiscsi requirement to 1.10
to have all function and macros defined. The patch fixes also a
off-by-one error in the NOP timeout calculation which was fixed
while touching these code parts.

kvm: First step to push iothread lock out of inner run loop
This opens the path to get rid of the iothread lock on vmexits in KVM
mode. On x86, the in-kernel irqchips has to be used because we otherwise
need to synchronize APIC and other per-cpu state accesses that could be
changed concurrently.
Regarding pre/post-run callbacks, s390x and ARM should be fine without
specific locking as the callbacks are empty. MIPS and POWER require
locking for the pre-run callback.
For the handle_exit callback, it is non-empty in x86, POWER and s390.
Some POWER cases could do without the locking, but it is left in
place for now.

memory: let address_space_rw/ld*/st* run outside the BQL
The MMIO case is further broken up in two cases: if the caller does not
hold the BQL on invocation, the unlocked one takes or avoids BQL depending
on the locking strategy of the target memory region and its coalesced
MMIO handling. In this case, the caller should not hold _any_ lock
(a friendly suggestion which is disregarded by virtio-scsi-dataplane).

main-loop: introduce qemu_mutex_iothread_locked
This function will be used to avoid recursive locking of the iothread lock
whenever address_space_rw/ld*/st* are called with the BQL held, which is
almost always the case.
Tracking whether the iothread is owned is very cheap (just use a TLS
variable) but requires some care because now the lock must always be
taken with qemu_mutex_lock_iothread(). Previously this wasn't the case.
Outside TCG mode this is not a problem. In TCG mode, we need to be
careful and avoid the "prod out of compiled code" step if already
in a VCPU thread. This is easily done with a check on current_cpu,
i.e. qemu_in_vcpu_thread().
Hopefully, multithreaded TCG will get rid of the whole logic to kick
VCPUs whenever an I/O event occurs!

Fix irq route entries exceeding KVM_MAX_IRQ_ROUTES
Last month, we experienced several guests crash(6cores-8cores), qemu logs
display the following messages:
qemu-system-x86_64: /build/qemu-2.1.2/kvm-all.c:976:
kvm_irqchip_commit_routes: Assertion `ret == 0' failed.
After analysis and verification, we can confirm it's irq-balance
daemon(in guest) leads to the assertion failure. Start a 8 core guest with
two disks, execute the following scripts will reproduce the BUG quickly:
irq_affinity.sh
========================================================================
vda_irq_num=25
vdb_irq_num=27
while [ 1 ]
do
for irq in {1,2,4,8,10,20,40,80}
do
echo $irq > /proc/irq/$vda_irq_num/smp_affinity
echo $irq > /proc/irq/$vdb_irq_num/smp_affinity
dd if=/dev/vda of=/dev/zero bs=4K count=100 iflag=direct
dd if=/dev/vdb of=/dev/zero bs=4K count=100 iflag=direct
done
done
========================================================================
QEMU setup static irq route entries in kvm_pc_setup_irq_routing(), PIC and
IOAPIC share the first 15 GSI numbers, take up 23 GSI numbers, but take up
38 irq route entries. When change irq smp_affinity in guest, a dynamic route
entry may be setup, the current logic is: if allocate GSI number succeeds,
a new route entry can be added. The available dynamic GSI numbers is
1021(KVM_MAX_IRQ_ROUTES-23), but available irq route entries is only
986(KVM_MAX_IRQ_ROUTES-38), GSI numbers greater than route entries.
irq-balance's behavior will eventually leads to total irq route entries
exceed KVM_MAX_IRQ_ROUTES, ioctl(KVM_SET_GSI_ROUTING) fail and
kvm_irqchip_commit_routes() trigger assertion failure.
This patch fix the BUG.

resetting the indicators, or else a guest will not be able to e.g.
switch from classic interrupts to adapter interrupts.
Split off this routine into a new function virtio_ccw_reset_virtio()
to make the distinction between resetting the virtio-related devices
and the base subchannel device clear.

The defs are only used by cpu-exec and translate-all which are both
arch-obj's so the new tb-hash.h has no core code usage.

hw/arm/virt: Make block devices default to virtio
Now we have virtio-pci, we can make the virt board's default block
device type be IF_VIRTIO. This allows users to use simplified
command lines that don't have to explicitly create virtio-pci-blk
devices; the -hda &c very short options now also work.
This means we also need to set no_cdrom to avoid getting a
default cdrom device -- this is needed because the virtio-blk
device will fail if it is connected to a block backend with
no media, which is what the default cdrom device typically is.
Providing a cdrom with media via -cdrom will succeed, but silently
create a device with non-removable medium. this is probably
not really what the user wants, but is the best we can do now.
Note that this change means that some command lines which used
to work (by accident) will stop working. Where a drive was connected
manually to a device but without 'if=none' being specified, we
used to treat this as an IDE drive, which we would then not autoplug
because the board doesn't support IDE. Now we will treat it as a
virtio disk and autoplug it, which means the attempt to use the
drive manually will fail:
qemu-system-arm: -drive file=img.qcow2,id=foo: Drive 'foo' is already
in use because it has been automatically connected to another device
(did you need 'if=none' in the drive options?)
The command line will have to be changed to include 'if=none', as the
error message suggests.

qdev-properties-system: Improve error message for drive assignment conflict
If the user forgot if=none on their drive specification they're likely
to get an error message because the drive is assigned once automatically
by QEMU and once by the manual id=/drive= user command line specification.
Improve the error message produced in this case to explicitly guide the
user towards if=none.
We rephrase the "drive conflict but not for an if=something" error as
well to keep the wording in line.
The two cases that change are:
(1) Drive specified as to be auto-connected and also manually connected
(and the board does handle this if= type):
qemu-system-x86_64 -nodefaults -display none \
-drive if=scsi,file=tmp.qcow2,id=foo -device ide-hd,drive=foo
Previously:
qemu-system-x86_64: -device ide-hd,drive=foo: Property 'ide-hd.drive'
can't take value 'foo', it's in use
Now:
qemu-system-x86_64: -device ide-hd,drive=foo: Drive 'foo' is already in
use because it has been automatically connected to another device (did
you need 'if=none' in the drive options?)
(2) Drive specified to be manually connected in two different ways:
qemu-system-x86_64 -nodefaults -display none \
-drive if=none,file=tmp.qcow2,id=foo -device ide-hd,drive=foo \
-device ide-hd,drive=foo
Previously:
qemu-system-x86_64: -device ide-hd,drive=foo: Property 'ide-hd.drive'
can't take value 'foo', it's in use
Now:
qemu-system-x86_64: -device ide-hd,drive=foo: Drive 'foo' is already in
use by another device

Instead of having set_pointer() call a parse callback which returns
an error number that we then convert to an Error string with
error_set_from_qdev_prop_error(), make the parse callback take an
Error** and set the error itself. This will allow parse routines
to provide more helpful error messages than the generic ones.

It has to raise RI exception when PS type is not implemented. (FIR.PS = 0)
(The PS data type is removed in the Release 6.)
Loongson-2E and Loongson-2F don't have any implementation field in
FCSR0(FIR) but do support PS data format, therefore for these cores RI will
not be signalled regardless of PS bit.

hw/mips: Do not clear BEV for MIPS malta kernel load
The BEV flag controls whether the boot exception vector is still
in place when starting a kernel. When cleared the exception vector
at EBASE (or hard coded address of 0x80000000) is used instead.
The early stages of the linux kernel would benefit from BEV still
being set to ensure any faults get handled by the boot rom exception
handlers. This is a moot point for system qemu as there aren't really
any BEV handlers, but there are other good reasons to change this...
The UHI (semi-hosting interface) defines special behaviours depending
on whether an application starts in an environment with BEV set or
cleared. When BEV is set then UHI assumes that a bootloader is
relatively dumb and has no advanced exception handling logic.
However, when BEV is cleared then UHI assumes that the bootloader
has the ability to handle UHI exceptions with its exception handlers
and will unwind and forward UHI SYSCALL exceptions to the exception
vector that was installed prior to running the application.

hw/pci-bridge: format special OFW unit address for PXB host
We have agreed that OpenFirmware device paths in the "bootorder" fw_cfg
file should follow the pattern
/pci@i0cf8,%x/...
for devices that live behind an extra root bus. The extra root bus in
question is the %x'th among the extra root buses. (In other words, %x
gives the position of the affected extra root bus relative to the other
extra root buses, in bus_nr order.) %x starts at 1, and is formatted in
hex.
The portion of the unit address that comes before the comma is dynamically
taken from the main host bridge, similarly to sysbus_get_fw_dev_path().

hw/core: explicit OFW unit address callback for SysBusDeviceClass
The sysbus_get_fw_dev_path() function formats OpenFirmware device path
nodes ("driver-name@unit-address") for sysbus devices. The first choice
for "unit-address" is the base address of the device's first MMIO region.
The second choice is its first IO port.
However, if two sysbus devices with the same "driver-name" lack both MMIO
and PIO resources, then there is no good way to distinguish them based on
their OFW nodes, because in this case unit-address is omitted completely
for both devices. An example is TYPE_PXB_HOST ("pxb-host").
For the sake of such devices, introduce the explicit_ofw_unit_address()
"virtual member function". With this function, each sysbus device in the
same SysBusDeviceClass can state its own address.

hw/pci-bridge: disable SHPC in PXB
OVMF downloads the ACPI linker/loader script from QEMU when the edk2 PCI
Bus driver globally signals the firmware that PCI enumeration and resource
allocation have completed. At this point QEMU regenerates the ACPI payload
in an fw_cfg read callback, and this is when the PXB's _CRS gets
populated.
Unfortunately, when this happens, the PCI_COMMAND_MEMORY bit is clear in
the root bus's command register, *unlike* under SeaBIOS. The consequences
unfold as follows:
- When build_crs() fetches dev->io_regions[i].addr, it is all-bits-one,
because pci_update_mappings() --> pci_bar_address() calculated it as
PCI_BAR_UNMAPPED, due to the PCI_COMMAND_MEMORY bit being clear.
- Consequently, the SHPC MMIO BAR (bar 0) of the bridge is not added to
the _CRS, *despite* having been programmed in PCI config space.
- Similarly, the SHPC MMIO BAR of the PXB is not removed from the main
root bus's DWordMemory descriptor.
- Guest OSes (Linux and Windows alike) notice the pre-programmed SHPC BAR
within the PXB's config space, and notice that it conflicts with the
main root bus's memory resource descriptors. Linux reports
pci 0000:04:00.0: BAR 0: can't assign mem (size 0x100)
pci 0000:04:00.0: BAR 0: trying firmware assignment [mem
0x88200000-0x882000ff 64bit]
pci 0000:04:00.0: BAR 0: [mem 0x88200000-0x882000ff 64bit] conflicts
with PCI Bus 0000:00 [mem
0x88200000-0xfebfffff]
While Windows Server 2012 R2 reports
https://technet.microsoft.com/en-us/library/cc732199%28v=ws.10%29.aspx
This device cannot find enough free resources that it can use. If you
want to use this device, you will need to disable one of the other
devices on this system. (Code 12)
This issue was apparently encountered earlier, see the "hack" in:
https://lists.nongnu.org/archive/html/qemu-devel/2015-01/msg02983.html
and the current hole-punching logic in build_crs() and build_ssdt() is
probably supposed to remedy exactly that problem -- however, for OVMF they
don't work, because at the end of the PCI enumeration and resource
allocation, which cues the ACPI linker/loader client, the command register
is clear.
The "shpc" property of "pci-bridge", introduced in the previous patches,
allows us to disable the standard hotplug controller cleanly, eliminating
the SHPC bar and the conflict.

There is no _TEST() variant of VMSTATE_BUFFER_UNSAFE_INFO() yet, but we'll

The parameter order of the new function-like macro follows that of
VMSTATE_SINGLE_TEST(): "_test" is introduced between "_state" and
"_version".

commit 3de3d698d942d1116152417f882c897b26b44e41
Author: Wolfgang Bumiller <w.bumiller@proxmox.com>
Date: Thu May 21 14:33:29 2015 +0200
util/qemu-sockets: improve ai_flag hints for ipv6 hosts
*) Do not use AI_ADDRCONFIG on listening sockets, because this flag
makes it impossible to explicitly listen on '127.0.0.1' if no global
ipv4 address is configured additionally, making this a very
uncomfortable option.
*) Add AI_V4MAPPED hint for connecting sockets.
If your system is globally only connected via ipv6 you often still want
to be able to use '127.0.0.1' and 'localhost' (even if localhost doesn't
also have an ipv6 entry).
For example, PVE - unless explicitly asking for insecure mode - uses
ipv4 loopback addresses with QEMU for live migrations tunneled over SSH.
These fail to start because AI_ADDRCONFIG makes getaddrinfo refuse to
work with '127.0.0.1'.
As for the AI_V4MAPPED flag: glibc uses it by default, and providing
non-0 flags removes it. I think it makes sense to use it.
I also want to point out that glibc explicitly sidesteps POSIX standards
when passing 0 as hints by then assuming both AI_V4MAPPED and
AI_ADDRCONFIG (the latter being a rather weird choice IMO), while
according to POSIX.1-2001 it should be assumed 0. (glibc considers its
choice an improvement.)
Since either AI_CANONNAME or AI_PASSIVE are passed in our cases, glibc's
default flags in turn are disabled again unless explicitly added, which
I do with this patch.

remove libdecnumber/dpd/decimal128Local.h
Commit 72ac97cdfc added two equivalent versions of decimal128Local.h,
one in libdecnumber/dpd/ and another in include/libdecnumber/dpd/.
Being identical by the code, the two files however differs in the
licensing terms. The one in libdecnumber/dpd/ (which is being
removed by this patch) is licensed as GPL3.1 (plus gcc runtime
exception), which, as far as I know, is not compatible with GPL-2.
This file is not used (it is included from
include/libdecnumber/dpd/decimal128.h, so version in include/ is
used).
More, the version in include/ can also be removed, since none
of the 3 defines from that file are actually used by the code.
Even more, one of the defines from there, decimal128SetSign,
is redefined (to equivalent value) in libdecnumber/dpd/decimal128.c,
but again, never used.
What a mess...

Revert "xen-hvm: increase maxmem before calling xc_domain_populate_physmap"
This reverts commit c1d322e6048796296555dd36fdd102d7fa2f50bf.
The original commit fixes a bug when assigning a large number of
devices which require option roms to a guest. (One known
configuration that needs extra memory is having more than 4 emulated
NICs assigned. Three or fewer NICs seems to work without this
functionality.)
However, by unilaterally increasing maxmem, it introduces two
problems.
First, now libxl's calculation of the required maxmem during migration
is broken -- any guest which exercised this functionality will fail on
migration. (Guests which have the default number of devices are not
affected.)
Secondly, it makes it impossible for a higher-level toolstack or
administer to predict how much memory a VM will actually use, making
it much more difficult to effectively use all of the memory on a
machine.

Expecting the ROM BAR to be written with an all ones value when sizing

balloon: add a feature bit to let Guest OS deflate balloon on oom
Excessive virtio_balloon inflation can cause invocation of OOM-killer,
when Linux is under severe memory pressure. Various mechanisms are
responsible for correct virtio_balloon memory management. Nevertheless it
is often the case that these control tools does not have enough time to
react on fast changing memory load. As a result OS runs out of memory and
invokes OOM-killer. The balancing of memory by use of the virtio balloon
should not cause the termination of processes while there are pages in the
balloon. Now there is no way for virtio balloon driver to free memory at
the last moment before some process get killed by OOM-killer.
This does not provide a security breach as balloon itself is running
inside Guest OS and is working in the cooperation with the host. Thus
some improvements from Guest side should be considered as normal.
To solve the problem, introduce a virtio_balloon callback which is
expected to be called from the oom notifier call chain in out_of_memory()
function. If virtio balloon could release some memory, it will make the
system return and retry the allocation that forced the out of memory
killer to run.
This behavior should be enabled if and only if appropriate feature bit
is set on the device. It is off by default.
This functionality was recently merged into vanilla Linux.

raw-posix: Introduce hdev_is_sg()
Until now, an SG device was identified only by checking if its path
started with "/dev/sg". Then, hdev_open() would set the bs->sg flag
accordingly. The patch relies on the actual properties of the device
instead of the specified file path.
To this end, test for an SG device (e.g. /dev/sg0) by ensuring that
all of the following holds:
- The specified file name corresponds to a character device
- The device supports the SG_GET_VERSION_NUM ioctl
- The device supports the SG_GET_SCSI_ID ioctl

Fix migration in case of scsi-generic
During migration, QEMU uses fsync()/fdatasync() on the open file
descriptor for read-write block devices to flush data just before
stopping the VM.
However, fsync() on a scsi-generic device returns -EINVAL which
causes the migration to fail. This patch skips flushing data in case
of an SG device, since submitting SCSI commands directly via an SG
character device (e.g. /dev/sg0) bypasses the page cache completely,
anyway.
Note that fsync() not only flushes the page cache but also the disk
cache. The scsi-generic device never sends flushes, and for
migration it assumes that the same SCSI device is used by the
destination host, so it does not issue any SCSI SYNCHRONIZE CACHE
(10) command.
Finally, remove the bdrv_is_sg() test from iscsi_co_flush() since
this is now redundant (we flush the underlying protocol at the end
of bdrv_co_flush() which, with this patch, we never reach).

This patch replaces blk_drain_all() by blk_drain() in
virtio_blk_reset(). virtio_blk_data_plane_stop() should be called
after draining because it restores vblk->complete_request.

throttle: Check current timers before updating any_timer_armed[]
Calling throttle_group_config() cancels all timers from a particular
BlockDriverState, so any_timer_armed[] should be updated accordingly.
However, with the current code it may happen that a timer is armed in
a different BlockDriverState from the same group, so any_timer_armed[]
would be set to false in a situation where there is still a timer
armed.
The consequence is that we might end up with two timers armed. This
should not have any noticeable impact however, since all accesses to
the ThrottleGroup are protected by a lock, and the situation would
become normal again shortly thereafter as soon as all timers have been
fired.
The correct way to solve this is to check that we're actually
cancelling a timer before updating any_timer_armed[].

block: Let bdrv_drain_all() to call aio_poll() for each AioContext
After the commit 9b536adc ("block: acquire AioContext in
bdrv_drain_all()") the aio_poll() function got called for every
BlockDriverState, in assumption that every device may have its own
AioContext. If we have thousands of disks attached, there are a lot of
BlockDriverStates but only a few AioContexts, leading to tons of
unnecessary aio_poll() calls.
This patch changes the bdrv_drain_all() function allowing it find shared
AioContexts and to call aio_poll() only for unique ones.

qmp: Wean off qerror_report()
The traditional QMP command handler interface
int qmp_FOO(Monitor *mon, const QDict *params, QObject **ret_data);
doesn't provide for returning an Error object. Instead, the handler
is expected to stash it in the monitor with qerror_report().
When we rebased QMP on top of QAPI, we didn't change this interface.
Instead, commit 776574d introduced "middle mode" as a temporary aid
for converting existing QMP commands to QAPI one by one. More than
three years later, we're still using it.
Middle mode has two effects:
* Instead of the native input marshallers
static void qmp_marshal_input_FOO(QDict *, QObject **, Error **)
it generates input marshallers conforming to the traditional QMP
command handler interface.
* It suppresses generation of code to register them with
qmp_register_command()
This permits giving them internal linkage.
As long as we need qmp-commands.hx, we can't use the registry behind
qmp_register_command(), so the latter has to stay for now.
The former has to go to get rid of qerror_report(). Changing all QMP
commands to fit the QAPI mold in one go was impractical back when we
started, but by now there are just a few stragglers left:
do_qmp_capabilities(), qmp_qom_set(), qmp_qom_get(), qmp_object_add(),
qmp_netdev_add(), do_device_add().
Switch middle mode to generate native input marshallers, and adapt the
stragglers. Simplifies both the monitor code and the stragglers.
Rename do_qmp_capabilities() to qmp_capabilities(), and
do_device_add() to qmp_device_add, because that's how QMP command
handlers are named today.

qerror: Clean up QERR_ macros to expand into a single string
These macros expand into error class enumeration constant, comma,
string. Unclean. Has been that way since commit 13f59ae.
The error class is always ERROR_CLASS_GENERIC_ERROR since the previous
commit.
Clean up as follows:
* Prepend every use of a QERR_ macro by ERROR_CLASS_GENERIC_ERROR, and
delete it from the QERR_ macro. No change after preprocessing.
* Rewrite error_set(ERROR_CLASS_GENERIC_ERROR, ...) into
error_setg(...). Again, no change after preprocessing.

QemuOpts: Wean off qerror_report_err()
qerror_report_err() is a transitional interface to help with
converting existing monitor commands to QMP. It should not be used
elsewhere.
The only remaining user in qemu-option.c is qemu_opts_parse(). Is it
used in QMP context? If not, we can simply replace
qerror_report_err() by error_report_err().
The uses in qemu-img.c, qemu-io.c, qemu-nbd.c and under tests/ are
clearly not in QMP context.
The uses in vl.c aren't either, because the only QMP command handlers
there are qmp_query_status() and qmp_query_machines(), and they don't
call it.
Remaining uses:
* drive_def(): Command line -drive and such, HMP drive_add and pci_add
* hmp_chardev_add(): HMP chardev-add
* monitor_parse_command(): HMP core
* tmp_config_parse(): Command line -tpmdev
* net_host_device_add(): HMP host_net_add
* net_client_parse(): Command line -net and -netdev
* qemu_global_option(): Command line -global
* vnc_parse_func(): Command line -display, -vnc, default display, HMP
change, QMP change. Bummer.
* qemu_pci_hot_add_nic(): HMP pci_add
* usb_net_init(): Command line -usbdevice, HMP usb_add
Propagate errors through qemu_opts_parse(). Create a convenience
function qemu_opts_parse_noisily() that passes errors to
error_report_err(). Switch all non-QMP users outside tests to it.
That leaves vnc_parse_func(). Propagate errors through it. Since I'm
touching it anyway, rename it to vnc_parse().

qdev-monitor: Fix check for full bus
Property bus has always been too screwed up to be really usable for
values other than plain bus IDs. This just fixes a bug that crept in
in commit 1395af6 "qdev: add a maximum device allowed field for the
bus."
It doesn't always fail when it should:
$ qemu-system-x86_64 -nodefaults -device virtio-serial-pci -device virtio-rng-device,bus=pci.0/virtio-serial-pci/virtio-bus
Happily plugs the virtio-rng-device into the virtio-bus provided by
virtio-serial-pci, even though its only slot is already occupied by a
virtio-serial-device.
And sometimes fails when it shouldn't:
$ qemu-system-x86_64 -nodefaults -device virtio-serial-pci -device virtserialport,bus=virtio-bus/virtio-serial-device
Yes, the virtio-bus is full, but the virtio-serial-bus provided by
virtio-serial-device isn't, and that's the one we're trying to use.
Root cause: we check "bus full" when we resolve the first element of
the path. That's the correct one only when it's also the last one.
Fix by moving the "bus full" check to right before we return a bus.

qdev-monitor: Stop error avalanche in qbus_find_recursive()
Reproducer:

qemu-system-x86_64: -device virtio-rng-device,bus=virtio-bus: Bus 'virtio-bus' is full

qemu-system-x86_64: -device virtio-rng-device,bus=virtio-bus: Bus 'virtio-bus' not found
qbus_find_recursive() reports the "is full" error itself, and leaves
reporting "not found" to its caller. The result is confusion. Write
it a function contract that permits leaving all error reporting to the
caller, and implement it. Update callers to detect and report "is
full".
Screwed up when commit 1395af6 added the max_dev limit and the "is
full" error condition to enforce it.

monitor: Split mon_get_cpu fn to remove ENV_GET_CPU
The monitor currently has one helper, mon_get_cpu() which will return
an env pointer. The target specific users of this API want an env, but
all the target agnostic users really just want the cpu pointer. These
users then need to use the target-specifically defined ENV_GET_CPU to
navigate back up to the CPU from the ENV. Split the API for the two
uses cases to remove all need for ENV_GET_CPU.

m68k: fix usp processing on interrupt entry and exception exit
The action to potentially switch sp register is not occurring at the correct
point in the interrupt entry or exception exit sequences.
For the interrupt entry case the sp on entry is used to create the stack
exception frame - but this may well be the user stack pointer, since we
haven't done the switch yet. Re-order the flow to switch the sp regs then
use the current sp to create the exception frame.
For the return from exception case the code is unwinding the sp after
switching sp registers. But it should always unwind the supervisor sp
first, then carry out any required sp switch.
Note that these problems don't effect operation unless the user sp bit is
set in the CACR register. Only a single sp is used in the default power up
state. Previously Linux only used this single sp mode. But modern versions
of Linux use the user sp mode now, so we need correct behavior for Linux
to work.

ml605_mmu: Move the hardcoded values to the init function
Move the hard coded register values to the init function.
This also allows the entire reset function to be deleted, as
PVR registers are now preserved on reset.
The hardcoded PVR0 values can be removed as they are setting
the endianness and stack protection, which is already done
or invalid.

qom: Don't pass string table to object_get_enum() function
Now that properties can be explicitly registered as an enum
type, there is no need to pass the string table to the
object_get_enum() function. The object property registration
already has a pointer to the string table.
In changing this method signature, the hostmem backend object
has to be converted to use the new enum property registration
code, which simplifies it somewhat.

qom: Add an object_property_add_enum() helper function
A QOM property can be parsed as enum using the visit_type_enum()
helper function, but this forces callers to use the more complex
generic object_property_add() method when registering it. It
also requires that users of that object have access to the
string map when they want to read the property value.
This patch introduces a specialized object_property_add_enum()
method which simplifies the use of enum properties, so the
setters/getters directly get passed the int value.
typedef enum {
MYDEV_TYPE_FROG,
MYDEV_TYPE_ALLIGATOR,
MYDEV_TYPE_PLATYPUS,
MYDEV_TYPE_LAST
} MyDevType;
Then provide a table of enum <-> string mappings
static const char *const mydevtypemap[MYDEV_TYPE_LAST + 1] = {
[MYDEV_TYPE_FROG] = "frog",
[MYDEV_TYPE_ALLIGATOR] = "alligator",
[MYDEV_TYPE_PLATYPUS] = "platypus",
[MYDEV_TYPE_LAST] = NULL,
};
Assuming an object struct of
typedef struct {
Object parent_obj;
MyDevType devtype;
...other fields...
} MyDev;
The property can then be registered as follows:
static int mydev_prop_get_devtype(Object *obj,
Error **errp G_GNUC_UNUSED)
{
MyDev *dev = MYDEV(obj);
return dev->devtype;
}
static void mydev_prop_set_devtype(Object *obj,
int value,
Error **errp G_GNUC_UNUSED)
{
MyDev *dev = MYDEV(obj);
dev->devtype = value;
}
object_property_add_enum(obj, "devtype",
mydevtypemap, "MyDevType",
mydev_prop_get_devtype,
mydev_prop_set_devtype,
NULL);
Note there is no need to check the range of 'value' in
the setter, because the string->enum conversion code will
have already done that and reported an error as required.

qom: Add object_new_with_props() / object_new_withpropv() helpers
It is reasonably common to want to create an object, set a
number of properties, register it in the hierarchy and then
mark it as complete (if a user creatable type). This requires
quite a lot of error prone, verbose, boilerplate code to achieve.
First a pair of functions object_set_props() / object_set_propv()
are added which allow for a list of objects to be set in
one single API call.
Then object_new_with_props() / object_new_with_propv() constructors
are added which simplify the sequence of calls to create an
object, populate properties, register in the object composition
tree and mark the object complete, into a single method call.
Usage would be:
Error *err = NULL;
Object *obj;
obj = object_new_with_propv(TYPE_MEMORY_BACKEND_FILE,
object_get_objects_root(),
"hostmem0",
&err,
"share", "yes",
"mem-path", "/dev/shm/somefile",
"prealloc", "yes",
"size", "1048576",
NULL);
Note all property values are passed in string form and will
be parsed into their required data types, using normal QOM
semantics for parsing from string format.

vl: Create (most) objects before creating chardev backends
Some types of object must be created before chardevs, other types of
object must be created after chardevs. As such there is no option but
to create objects in two phases.
This takes the decision to create as many object types as possible
right away before anyother backends are created, and only delay
creation of those few which have an explicit dependency on the
chardevs. Hopefully the set which need delaying will remain small
over time.

semihosting: add --semihosting-config arg sub-argument
Add new "arg" sub-argument to the --semihosting-config allowing the user
to pass multiple input arguments separately. It is required for example
by UHI semihosting to construct argc and argv.
Also, update ARM semihosting to support new option (at the moment it is
the only target which cares about arguments).
If the semihosting is enabled and no semihosting args have been specified,
then fall back to -kernel/-append. The -append string is split on whitespace
before initializing semihosting.argv[1..n]; this is different from what
QEMU MIPS machines' pseudo-bootloaders do (i.e. argv[1] contains the whole
-append), but is more intuitive from UHI user's point of view and Linux
kernel just does not care as it concatenates argv[1..n] into single cmdline
string anyway.

target-arm: Do not reset sysregs marked as ALIAS
cp_reg_reset() is called from g_hash_table_foreach() which does not
define a specific ordering of the hash table iteration. Thus doing reset
for registers marked as ALIAS would give an ambiguous result when
resetvalue is different for original and alias registers. Exit
cp_reg_reset() early when passed an alias register. Then clean up alias
register definitions from needless resetvalue and resetfn.
In particular, this fixes a bug in the handling of the PMCR register,
which had different resetvalues for its 32 and 64-bit views.

If these registers are implemented via separate MemoryRegions, it is
wrong to clamp the accesses as the value written would be truncated.
Hence for these regions the effects of commit 23820db (exec: Respect

mc146818rtc: Reset the periodic timer on load
When loading a VM from a snapshot or migration, clock changes can cause
the periodic timer to stall or loop rapidly.
qemu-timer has a reset notifier mechanism that is used to avoid timer
stalls or loops if the host clock changes while the VM is running when
using QEMU_CLOCK_HOST. However, when loading a snapshot or migration,
qemu-timer is initialized and fires the reset notifier before
mc146818rtc is initialized and has registered its reset handler. In
addition, this mechanism isn't used when using QEMU_CLOCK_REALTIME,
which might also change when loading a snapshot or migration.
To correct that problem, this commit resets the periodic timer after
loading from a snapshot or migration if the clock has either jumped
backward or has jumped forward by more than the clock jump limit that
is used by the reset notifier code in qemu-timer.

qemu-timer: Call clock reset notifiers on forward jumps
Commit 691a0c9c introduced a mechanism by which QEMU_CLOCK_HOST can
notify other parts of the emulator when the host clock has jumped
backward. This is used to avoid stalling timers that were scheduled
based on the host clock.
However, if the host clock jumps forward, then timers that were
scheduled based on the host clock may fire rapidly and cause other
problems. For example, the mc146818rtc periodic timer will block
execution of the VM and consume host CPU while firing every interrupt
for the time period that was skipped by the host clock.
To correct that problem, this commit fires the reset notification if the
host clock jumps forward by more than a hard-coded limit. The limit is
currently set to a value of 60 seconds, which should be small enough to
prevent excessive timer loops, but large enough to avoid frequent resets
in idle VMs.

vhost: enable vhost without without MSI-X
We use vhostforce to enable vhost even if Guests don't have MSI-X
support and we fall back to QEMU virtio-net.
This gives a very small performance gain, but the disadvantage
is that guest now controls which virtio code is running
(qemu or vhost) so our attack surface is doubled.
This patch will enable vhost unconditionally whenever it's requested.
For compatibility, enable vhost when vhostforce is set, as well.

pci: Don't register a specialized 'config_write' if default behavior is intended
Few devices have their specialized 'config_write' methods which simply
call 'pci_default_write_config' followed by a 'msix_write_config' or
'msi_write_config' calls, using exact same arguments.
This is unnecessary as 'pci_default_write_config' already invokes
'msi_write_config' and 'msix_write_config'.
Also, since 'pci_default_write_config' is the default 'config_write'
handler, we can simply avoid the registration of these specialized
versions.

i8254: fix out-of-bounds memory access in pit_ioport_read()
Due converting PIO to the new memory read/write api we no longer provide
separate I/O region lenghts for read and write operations. As a result,
reading from PIT Mode/Command register will end with accessing
pit->channels with invalid index.
Fix this by ignoring read from the Mode/Command register.

qemu-ga: adding vss-[un]install options
Existing command line options include '-s install' and '-s uninstall'.
These options install/uninstall both Windows QEMU GA service

enables guest agent integration with Volume Shadow Service.
This commit introdices new options '-s vss-install' and '-s vss-uninstall',

for registering and unregistering the COM server during MSI installation,

qemu-log: Open file for logging when specified
qemu-log defaults to stderr when there is no '-D' option mentioned on command
line. When '-D' option is specified, we also need to specify '-d' option for it
to use the specified logfile. When using monitor to enable logging this is
troublesome since there will be no '-d' option because of which monitor dumps
the logs to stderr.
Fix this by opening the log file when '-D' is specified on the command line.
Also fix an ancient comment which does not hold true since changing location and
log level has now been streamlined.

We now finally have TCG support for the basic set of instructions necessary

type is now superior to the legacy s390-virtio machine.

translate-all: fix watchpoints if retranslation not possible
The tb_check_watchpoint function currently assumes that all memory
access is done either directly through the TCG code or through an
helper which knows its return address. This is obviously wrong as the
helpers use cpu_ldxx/stxx_data functions to access the memory.
Instead of aborting in that case, don't try to retranslate the code, but
assume that the CPU state (and especially the program counter) has been
saved before calling the helper. Then invalidate the TB based on this
address.

target-s390x: PER instruction-fetch event support
For the PER instruction-fetch, we can't use the QEMU breakpoint
infrastructure as it triggers for a single address and not a full
address range, and as it actually stop before the instruction and
not before.
We therefore call an helper with the just fetched instruction address,
which check if the address is within the PER address range. If it is
the case, an event is recorded and will be signaled through an
exception.
Note that we implement here the PER-3 behaviour, that is an invalid
opcode is not considered as an instruction fetch. Without PER-3 this
behavious is undefined.

target-s390x: PER successful-branching event support
For the PER successful-branching event support, we can't rely on any
QEMU infrastucture. We therefore call an helper in all places where
a branch can be taken. We have to pay attention to the branch to next
case, as it's still a taken branch.
We don't need to care about the cases using goto_tb, as we have disabled
them in the previous patch.

target-s390x: basic PER event handling
This patch add basic support to generate PER exceptions. It adds two
fields to the cpu structure to record for the PER address and PER
code & ATMID values. When an exception is triggered and a PER event is
pending, the two PER values are copied to the lowcore area.
At the end of an instruction, an helper is checking for a possible
pending PER event and triggers an exception in that case. For that to
work with branches, we need to disable TB chaining when PER is
activated. Fortunately it's already in the TB flags.
Finally in case of a SERVICE CALL exception, we need to trigger the PER
exception immediately after.

target-s390x: mvc_fast_memmove: access memory through softmmu
mvc_fast_memmove is bypassing the softmmu functions, getting the
physical source and destination addresses using the mmu_translate
function and accessing the corresponding physical memory. This
prevents watchpoints to work correctly.
Instead use the tlb_vaddr_to_host function to get the host addresses
corresponding to the guest source and destination addresses through the
softmmu code and fallback to the byte level code in case the
corresponding address are not in the QEMU TLB or being examined through
a watchpoint. As a bonus it works even for area crossing pages by
splitting the are into chunks contained in a single page, bringing some
performances improvements. We can therefore remove the 8-byte
loads/stores method, as it is now quite unlikely to be used.
At the same time change the name of the function to fast_memmove as it's
not specific to mvc and use the same argument order as the C memmove
function.

linux-user: ioctl() command type is int
When executing a 64bit target chroot on 64bit host,
the ioctl() command can mismatch.
It seems the previous commit doesn't solve the problem in
my case:
9c6bf9c7 linux-user: Fix ioctl cmd type mismatch on 64-bit targets
For example, a ppc64 chroot on an x86_64 host:
bash-4.3# ls
Unsupported ioctl: cmd=0x80087467
Unsupported ioctl: cmd=0x802c7415
The origin of the problem is in syscall.c:do_ioctl().
static abi_long do_ioctl(int fd, abi_long cmd, abi_long arg)
In this case (ppc64) abi_long is long (on the x86_64), and
cmd = 0x0000000080087467
then
if (ie->target_cmd == cmd)
target_cmd is int, so target_cmd = 0x80087467
and to compare an int with a long, the sign is extended to 64bit,
so the comparison is:
if (0xffffffff80087467 == 0x0000000080087467)
which doesn't match whereas it should.
This patch uses int in the case of the target command type
instead of abi_long.

linux-user: use __get_user and __put_user in cmsg conversions
The target payloads in cmsg conversions may not have the alignment
required by the host. Using the get_user and put_user functions is
the easiest way to handle this and also do the byte-swapping we
require.
(Note that prior to this commit target_to_host_cmsg was incorrectly
using __put_user() rather than __get_user() for the SCM_CREDENTIALS
conversion, which meant it wasn't getting the benefit of the
misalignment handling.)

linux-user: Fix length handling in host_to_target_cmsg
The previous code for handling payload length when converting
cmsg structures from host to target had a number of problems:
* we required the msg->msg_controllen to declare the buffer
to have enough space for final trailing padding (we were
checking against CMSG_SPACE), whereas the kernel does not
require this, and common userspace code assumes this. (In
particular, glibc's "try to talk to nscd" code that it will
run on startup will receive a cmsg with a 4 byte payload and
only allocate 4 bytes for it, which was causing us to do
the wrong thing on architectures that need 8-alignment.)
* we weren't correctly handling the fact that the SO_TIMESTAMP
payload may be larger for the target than the host
* we weren't marking the messages with MSG_CTRUNC when we did
need to truncate a message that wasn't truncated by the host,
but were instead logging a QEMU message; since truncation is
always the result of a guest giving us an insufficiently
sized buffer, we should report it to the guest as the kernel

Rewrite the parts of the function that deal with length to

to explain why the overflow logging it does is a QEMU bug,
not a guest issue.

target-arm: Correct "preferred return address" for cpreg access exceptions
The architecture defines that when taking an exception trying to
access a coprocessor register, the "preferred return address" for
the exception is the address of the instruction that caused the
exception. Correct an off-by-4 error which meant we were returning
the address after the instruction for traps which happened because
of a failure of a runtime access-check function on an AArch32
register. (Traps caused by translate-time checkable permissions
failures had the correct address, as did traps on AArch64 registers.)

arm: Add has-mpu property
For processors that support MPUs, add a property to de-feature it. This
is similar to the implementation of the EL3 feature.
The processor definition in init sets ARM_FEATURE_MPU if it can support
an MPU. post_init exposes the property, defaulting to true. If cleared
by the instantiator, ARM_FEATURE_MPU is then removed at realize time.
This is to support R profile processors that may or may-not have an MPU
configured.

arm: Refactor get_phys_addr FSR return mechanism
Currently, the return code for get_phys_addr is overloaded for both
success/fail and FSR value return. This doesn't handle the case where
there is an error with a 0 FSR. This case exists in PMSAv7.
So rework get_phys_addr and friends to return a success/failure boolean
return code and populate the FSR via a caller provided uint32_t

Create an ARM_FEATURE_THUMB_DSP controlling the Thumb encodings of
the 85 DSP instructions (these are all Thumb2). This is enabled for
all non-M-profile CPUs with Thumb2 support, as the instructions are
mandatory for R and A profiles. On M profile they are optional and
not present in the Cortex-M3 (though they are in the M4).
The effect of this commit is that we will now treat the DSP
encodings as illegal instructions on M3, when previously we
incorrectly implemented them.

descriptor has had extended base address fields which hold bits 39:32 of
translated address. These fields are IMPDEF in ARMv6 and ARMv7 without
LPAE support.

target-arm: Handle "extended small page" descriptors correctly
The old ARMv5-style page table format includes a kind of second level
descriptor named the "extended small page" format, whose primary purpose
is to allow specification of the TEX memory attribute bits on a 4K page.
This exists on ARMv6 and also (as an implementation extension) on XScale
CPUs; it's UNPREDICTABLE on v5.
We were mishandling this in two ways:
(1) we weren't implementing it for v6 (probably never noticed because
Linux will use the new-style v6 page table format there)
(2) we were not correctly setting the page_size, which is 4K, not 1K
The latter bug went unnoticed for years because the only thing which
the page_size affects is which TLB entries get flushed when the guest
does a TLB invalidate on an address in the page, and prior to commit
2f0d8631b7 we were doing a full TLB flush very frequently due to Linux's
habit of writing the SCTLR pointlessly a lot.
(We can assume that after commit 2f0d8631b7 the bug went unnoticed
for a year because nobody's actually using the Zaurus/XScale emulation...)
Report the correct page size for these descriptors, and permit them
on ARMv6 CPUs. This fixes a problem where a kernel image for Zaurus
can boot the kernel OK but gets random segfaults when it tries to
run userspace programs.

Starting with version 4.9, GCC assumes it can't safely dereference null
pointers, and uses this for some optimizations. On s390, the lowcore
memory is located at address 0, so this assumption is wrong and breaks
the s390-ccw firmware. Pass -fdelete-null-pointer-checks to avoid that.

Enabling this option just creates a playback buffer with the specified settings,

linux-user: Allocate thunk size dynamically
We store all struct types in an array of static size without ever
checking whether we overrun it. Of course some day someone (like me
in another, ancient ALSA enabling patch set) will run into the limit
without realizing it.
So let's make the allocation dynamic. We already know the number of
structs that we want to allocate, so we only need to pass the variable
into the respective piece of code.
Also, to ensure we don't accidently overwrite random memory, add some
asserts to sanity check whether a thunk is actually part of our array.

block: Fix reopen flag inheritance
When reopening an image, the block layer already takes care to reopen
bs->file as well with recalculated inherited flags. The same must happen
for any other child (most notably missing before this patch: backing
files).
If bs->file (or any other child) didn't originally inherit from bs, e.g.
because it was created separately and then only referenced, it must not
inherit flags on reopen either, so check the inherited_from field before
propagation the reopen down.
VMDK already reopened its extents manually; this code can now be
dropped.

block: Add BlockDriverState.inherits_from
Currently, the block layer assumes that any block node can have only one
parent, and if it has a parent, that it inherits some options/flags from
this parent.
This is not true any more: With references used in block device
creation, a single node can be used by multiple parents, or it can be
created separately and not inherit flags from any parent.
To handle reopens correctly, a node must know from which parent it
inherited options. This patch adds the information to BlockDriverState.

block: Add list of children to BlockDriverState
This allows iterating over all children of a given BDS, not only
including bs->file and bs->backing_hd, but also driver-specific
ones like VMDK extents or Quorum children.
For bdrv_swap(), the list of children of the swapped BDS stays at that
BDS (because that's where the pointers stay as well). The list head
moves and pointers to it must be fixed up therefore.
The list of children in the parent of the swapped BDS is not affected by
the swap. The contents of the BDS objects is swapped, so the existing
pointer in the parent automatically points to the newly swapped in BDS.

block: Drain requests before swapping nodes in bdrv_swap()
bdrv_swap() requires that there are no requests in flight on either of
the two devices. The request coroutine would work on the wrong
BlockDriverState object (with bs->opaque even being interpreted as a
different type potentially) and all sorts of bad things would result
from this.
The currently existing callers mostly ensure that there is no I/O
pending on nodes that are swapped. In detail, this is:
1. Live snapshots. This goes through qmp_transaction(), which calls
bdrv_drain_all() before doing anything. The command is executed
synchronously, so no new I/O can be issued concurrently.
2. snapshot=on in bdrv_open(). We're in the middle of opening the image
(both the original image and its temporary overlay), so there can't
be any I/O in flight yet.
3. Mirroring. bdrv_drain() is already used on the source device so that
the mirror doesn't miss anything. However, the main loop runs between
that and the bdrv_swap() (which is actually a bug, being addressed in
another series), so there is a small window in which new I/O might be
issued that would be in flight during bdrv_swap().
It is safer to just drain the request queue of both devices in
bdrv_swap() instead of relying on callers to do the right thing.

block: driver should override flags in bdrv_open()
The BDRV_O_PROTOCOL flag should have an impact only if no driver is
specified explicitly. Therefore, if bdrv_open() is called with an
explicit block driver argument (either through the options QDict or
through the drv parameter) and that block driver is a protocol block
driver, BDRV_O_PROTOCOL should be set; if it is a format block driver,
BDRV_O_PROTOCOL should be unset.
While there was code to unset the flag in case a format block driver
has been selected, it only followed the bdrv_fill_options() function
call whereas the flag in fact needs to be adjusted before it is used
there.
With that change, BDRV_O_PROTOCOL will always be set if the BDS should
be a protocol driver; if the driver has been specified explicitly, the
new code will set it; and bdrv_fill_options() will only "probe" a
protocol driver if BDRV_O_PROTOCOL is set. The probing after
bdrv_fill_options() cannot select a protocol driver.
Thus, bdrv_open_image() to open BDS.file is never called if a protocol
BDS is about to be created. With that change in turn it is impossible to
call bdrv_open_common() with a protocol drv and file != NULL, which
allows us to remove the bdrv_swap() call.
This change breaks a test case in qemu-iotest 051:
"-drive file=t.qcow2,file.driver=qcow2" now works because the explicitly
specified "qcow2" overrides the BDRV_O_PROTOCOL which is automatically
set for the "file" BDS (and the filename is just passed down).
Therefore, this patch removes that test case.

If a relatively large cluster size is chosen, the default of 1 MB L2
cache is not really appropriate. In this case, unless overridden by the
user, the default cache size should not be determined by its size in
bytes but by the number of L2 tables (clusters) it is supposed to
contain.
Note that without this patch, MIN_L2_CACHE_SIZE will effectively take
over the same role. However, providing space for just two L2 tables is
not enough to be the default.

- The active BDS computes if a wait must be done and arms the right

- If a wait must be done the token timer will be armed so the token

Revert "iothread: release iothread around aio_poll"
This reverts commit a0710f7995f914e3044e5899bd8ff6c43c62f916.
In qemu-devel email message <556DBF87.2020908@de.ibm.com>, Christian
Borntraeger writes:
Having many guests all with a kernel/ramdisk (via -kernel) and
several null block devices will result in hangs. All hanging
guests are in partition detection code waiting for an I/O to return
so very early maybe even the first I/O.
Reverting that commit "fixes" the hangs.
Reverting this commit for the 2.4 release. More time is needed to
investigate and correct this patch.

commit 5ff1547b756a820bc7b695fe393b25d82467d1fe

rocker: bring link up/down on PHY enable/disable
When the OS driver enables/disables the port, go ahead and set the port's
link status to up/down in response to the change. This more closely
emulates real hardware when the PHY for the port is brought up/down
and the PHY negotiates carrier (link status) with link partner. In
the case of qemu, the virtual rocker device can't really do link
negotiation with the link partner as that requires signally over a
physical medium (the wire), so just pretend the negotiation was
successful and bring the link up when the port is enabled.

return 0 and read poll will be disabled until netmap_send_completed is

target-mips: add MTHC0 and MFHC0 instructions
Implement MTHC0 and MFHC0 instructions. In MIPS32 they are used to access
upper word of extended to 64-bits CP0 registers.
In MIPS64, when CP0 destination register specified is the EntryLo0 or
EntryLo1, bits 1:0 of the GPR appear at bits 31:30 of EntryLo0 or
EntryLo1. This is to compensate for RI and XI, which were shifted to bits
63:62 by MTC0 to EntryLo0 or EntryLo1. Therefore creating separate
functions for EntryLo0 and EntryLo1.

target-mips: add CP0.PageGrain.ELPA support
CP0.PageGrain.ELPA enables support for large physical addresses. This field
is encoded as follows:
0: Large physical address support is disabled.
1: Large physical address support is enabled.
If this bit is a 1, the following changes occur to coprocessor 0 registers:
- The PFNX field of the EntryLo0 and EntryLo1 registers is writable and
concatenated with the PFN field to form the full page frame number.
- Access to optional COP0 registers with PA extension, LLAddr, TagLo is
defined.
P5600 can operate in 32-bit or 40-bit Physical Address Mode. Therefore if
XPA is disabled (CP0.PageGrain.ELPA = 0) then assume 32-bit Address Mode.
In MIPS64 assume 36 as default PABITS (when CP0.PageGrain.ELPA = 0).
env->PABITS value is constant and indicates maximum PABITS available on
a core, whereas env->PAMask is calculated from env->PABITS and is also
affected by CP0.PageGrain.ELPA.

Add a protective section footer
Badly formatted migration streams can go undetected or produce
misleading errors due to a lock of checking at the end of sections.
In particular a section that adds an extra 0x00 at the end
causes what looks like a normal end of stream and thus doesn't produce
any errors, and something that ends in a 0x01..0x04 kind of look
like real section headers and then fail when the section parser tries
to figure out which section they are. This is made worse by the
choice of 0x00..0x04 being small numbers that are particularly common
in normal section data.
This patch adds a section footer consisting of a marker (0x7e - ~)
followed by the section-id that was also sent in the header. If
they mismatch then it throws an error explaining which section was
being loaded.

s390x/watchdog: introduce diag288 watchdog device
This patch introduces a new diag288 watchdog device that will, just like
other watchdogs, monitor a guest and take corresponding actions when it
detects that the guest is not responding.
diag288 is s390x specific. The wiring to s390x KVM will be done in
separate patches.

i386/acpi-build: fix PXB workarounds for unsupported BIOSes
The patch
apci: fix PXB behaviour if used with unsupported BIOS
uses the following condition to see if a "PXB mem/IO chunk" has *not* been
configured by the BIOS:
(!range_base || range_base > range_limit)
When this condition evaluates to true, said patch *omits* the
corresponding entry from the _CRS.
Later on the patch checks for the opposite condition (with the intent of
*adding* entries to the _CRS if the "PXB mem/IO chunks" *have* been
configured). Unfortunately, the condition was negated incorrectly: only
the first ! operator was removed, which led to the nonsensical expression
(range_base || range_base > range_limit)
leading to bogus entries in the _CRS, and causing BSOD in Windows Server
2012 R2 when it runs on OVMF.
The correct negative of the condition seen at the top is
(range_base && range_base <= range_limit)
Fix the expressions.

i386/acpi-build: more traditional _UID and _HID for PXB root buses
The ACPI specification permits the _HID and _UID objects to evaluate to
strings. (See "6.1.5 _HID (Hardware ID)" and "6.1.12 _UID (Unique ID)" in
the ACPI v6.0 spec.)
With regard to related standards, the UEFI specification can also express
a device address composed from string _HID and _UID identifiers, inside
the Expanded ACPI Device Path Node. (See "9.3.3 ACPI Device Path", Table
49, in the UEFI v2.5 spec.)
However, numeric (integer) contents for both _HID and _UID are more
traditional. They are recommended by the UEFI spec for size reasons:
[...] the ACPI Device Path node is smaller and should be used if
possible to reduce the size of device paths that may potentially be
stored in nonvolatile storage [...]
External tools support them better (for example the --acpi_hid and
--acpi_uid options of "efibootmgr" only take numeric identifiers).
Finally, numeric _HID and _UID contents are existing practice in the QEMU
source.
This patch was tested with a Fedora 20 LiveCD and a preexistent Windows
Server 2012 R2 guest. Using "acpidump" and "iasl" in the Fedora guest, we
get, in the SSDT:
> Scope (\_SB)
> {
> Device (PC04)
> {
> Name (_UID, 0x04) // _UID: Unique ID
> Name (_HID, EisaId ("PNP0A03") /* PCI Bus */) // _HID: Hardware ID

Commit 94c2b6aff43c (mips_malta: support up to 2GiB RAM) provided
support for using over 256MB of RAM with the MIPS Malta board, including
capping the memsize variable that QEMUs pseudo-bootloader provides to
the kernel at 256MB in order to match YAMON. It didn't however provide
the ememsize variable which kernels supporting memory outside of the
unmapped address spaces (ie. EVA or highmem) may use to determine the
true size of the RAM present in the system.
Set ememsize to the size of RAM so that such kernels may use all
available memory without the user having to manually specifying its size
& location.

target-mips: add Config5.FRE support allowing Status.FR=0 emulation
This relatively small architectural feature adds the following:
FIR.FREP: Read-only. If FREP=1, then Config5.FRE and Config5.UFE are
available.
Config5.FRE: When enabled all single-precision FP arithmetic instructions,
LWC1/LWXC1/MTC1, SWC1/SWXC1/MFC1 cause a Reserved Instructions
exception.
Config5.UFE: Allows user to write/read Config5.FRE using CTC1/CFC1
instructions.
Enable the feature in MIPS64R6-generic CPU.

waste a pci slot for each you can compose a multifunction device this way:
qemu -device virtio-keyboard-pci,addr=0d.0,multifunction=on \

virtio-pci: fill VirtIOPCIRegions early.
Initialize the modern bar and the VirtIOPCIRegion fields early, in

pci bars to VirtIOPCIProxy.
This allows virtio-pci subclasses to change things before the
device_plugged callback applies them. virtio-vga will use that to
arrange regions in a way that virtio-vga is compatible to both stdvga
(in vga mode) and virtio-gpu-pci (in pci mode).

virtio-pci: correctly set host notifiers for modern bar
Currently, during host notifier set. We only add eventfd for legacy
bar, this is not correct since:
- Non-transitional device does not have legacy bar, so qemu will crash
since proxy->bar was not initialized.
- Modern device uses modern bar and notify cap to notify the device,
we should add eventfd for proxy->notify.
So this patch fixes the above two issues by adding eventfd based on
whether legacy or modern device were supported.

pcnet: force the buffer access to be in bounds during tx
4096 is the maximum length per TMD and it is also currently the size of
the relay buffer pcnet driver uses for sending the packet data to QEMU
for further processing. With packet spanning multiple TMDs it can
happen that the overall packet size will be bigger than sizeof(buffer),
which results in memory corruption.
Fix this by only allowing to queue maximum sizeof(buffer) bytes.
This is CVE-2015-3209.

bios-tables-test: handle false-positive smbios signature matches
It has been reported that sometimes the .rodata section of SeaBIOS,
containing the constant string against which the SMBIOS signature
ends up being compared, also falls within the guest f-segment. In
that case, the test obviously fails, unless we continue searching
for the *real* SMBIOS entry point.
Rather than stopping at the first match for the SMBIOS signature
("_SM_") in the f-segment (0xF0000-0xFFFFF), continue scanning
until either a valid entry point table is found, or the f-segment
has been exhausted.

tcg: fix dead computation for repeated input arguments
When the same temp is used twice or more as an input argument to a TCG
instruction, the dead computation code doesn't recognize the second use
as a dead temp. This is because the temp is marked as live in the same
loop where dead inputs are checked.
The fix is to split the loop in two parts. This avoid emitting a move
and using a register for the movcond instruction when used as "move if
true" on x86-64. This might bring more improvements on RISC TCG targets
which don't have outputs aliased to inputs.

tcg: fix register allocation with two aliased dead inputs
For TCG ops with two outputs registers (add2, sub2, div2, div2u), when
the same input temp is used for the two inputs aliased to the two
outputs, and when these inputs are both dead, the register allocation
code wrongly assigned the same register to the same output.
This happens for example with sub2 t1, t2, t3, t3, t4, t5, when t3 is
not used anymore after the TCG op. In that case the same register is
used for t1, t2 and t3.
The fix is to look for already allocated aliased input when allocating
a dead aliased input and check that the register is not already
used.

sdl2: fix crash in handle_windowevent() when restoring the screen size
The Ctrl-Alt-u keyboard shortcut restores the screen to its original
size. In the SDL2 UI this is done by destroying the window and
creating a new one. The old window emits SDL_WINDOWEVENT_HIDDEN when
it's destroyed, but trying to call SDL_GetWindowFromID() from that
event's window ID returns a null pointer. handle_windowevent() assumes
that the pointer is never null so it results in a crash.

vhost-user: Improve -netdev/netdev_add/-net/... error reporting
When -netdev vhost-user fails, it first reports a specific error, then
one or more generic ones, like this:
$ qemu-system-x86_64 -netdev vhost-user,id=foo,chardev=xxx
qemu-system-x86_64: -netdev vhost-user,id=foo,chardev=xxx: chardev "xxx" not found
qemu-system-x86_64: -netdev vhost-user,id=foo,chardev=xxx: No suitable chardev found
qemu-system-x86_64: -netdev vhost-user,id=foo,chardev=xxx: Device 'vhost-user' could not be initialized
With the command line, the messages go to stderr. In HMP, they go to
the monitor. In QMP, the last one becomes the error reply, and the
others go to stderr.
Convert net_init_vhost_user() and its helpers to Error. This
suppresses the unwanted unspecific error messages, and makes the
specific error the QMP error reply.

vl: Fail right after first bad -object
Failure to create an object with -object is a fatal error. However,
we delay the actual exit until all -object are processed. On the one
hand, this permits detection of genuine additional errors. On the
other hand, it can muddy the waters with uninteresting additional
errors, e.g. when a later -object tries to reference a prior one that
failed.
We generally stop right on the first bad option, so do that for
-object as well.

machine: Drop use of DEFAULT_RAM_SIZE in help text
As of commit 076b35b5a (machine: add default_ram_size to machine
class) we no longer have a global default ram size, but instead
machine specific defaults. When invoking qemu --help we don't know
which machine you selected, so we can't tell the user the default RAM
size in the help text anymore now.
Thus I don't see an easy way to expose the default ram size to the
user in the help text. The easiest option IMHO is to just drop this
piece of information.

atomics: add explicit compiler fence in __atomic memory barriers
__atomic_thread_fence does not include a compiler barrier; in the
C++11 memory model, fences take effect in combination with other
atomic operations. GCC implements this by making __atomic_load and
__atomic_store access memory as if the pointer was volatile, and
leaves no trace whatsoever of acquire and release fences in the
compiler's intermediate representation.
In QEMU, we want memory barriers to act on all memory, but at the same
time we would like to use __atomic_thread_fence for portability reasons.
Add compiler barriers manually around the __atomic_thread_fence.

q35: implement high SMRAM
When H_SMRAME is 1, low memory at 0xa0000 is left alone by
SMM, and instead the chipset maps the 0xa0000-0xbffff window at
0xfeda0000-0xfedbffff. This affects both the "non-SMM" view controlled
by D_OPEN and the SMM view controlled by G_SMRAME, so add two new
MemoryRegions and toggle the enabled/disabled state of all four
in mch_update_smram.

target-i386: use memory API to implement SMRAM
Remove cpu_smm_register and cpu_smm_update. Instead, each CPU

hw/i386: add a separate region that tracks the SMRAME bit
This region is exported at /machine/smram. It is "empty" if
SMRAME=0 and points to SMRAM if SMRAME=1. The CPU will
enable/disable it as it enters or exits SMRAM.
While touching nearby code, the existing memory region setup was
slightly inconsistent. The smram_region is *disabled* in order to open
SMRAM (because the smram_region shows the low VRAM instead of the RAM
at 0xa0000). Because SMRAM is closed at startup, the smram_region must
be enabled when creating the i440fx or q35 devices.

-global does not work for drivers that have a dot in their name, such as

To allow this usage, support the full QemuOpts key/value syntax for -global

The two formats do not conflict, because the key/value syntax does not have

target-i386: mask NMIs on entry to SMM
QEMU is not blocking NMIs on entry to SMM. Implementing this has to
cover a few corner cases, because:
- NMIs can then be enabled by an IRET instruction and there
is no mechanism to _set_ the "NMIs masked" flag on exit from SMM:
"A special case can occur if an SMI handler nests inside an NMI handler
and then another NMI occurs. [...] When the processor enters SMM while
executing an NMI handler, the processor saves the SMRAM state save map
but does not save the attribute to keep NMI interrupts disabled.
- However, there is some hidden state, because "If NMIs were blocked
before the SMI occurred [and no IRET is executed while in SMM], they
are blocked after execution of RSM." This is represented by the new
HF2_SMM_INSIDE_NMI_MASK bit. If it is zero, NMIs are _unblocked_
on exit from RSM.

2) IOMMU regions were not setting mr->ram_addr to a bogus value, initialize

To clarify, rename the function to cpu_physical_memory_all_dirty and return

translate-all: make less of tb_invalidate_phys_page_range depend on is_cpu_write_access
is_cpu_write_access is only set if tb_invalidate_phys_page_range is called
from tb_invalidate_phys_page_fast, and hence from notdirty_mem_write.
However:
- the code bitmap can be built directly in tb_invalidate_phys_page_fast
(unconditionally, since is_cpu_write_access would always be passed as 1);
- the virtual address is not needed to mark the page as "not containing
code" (dirty code bitmap = 1), so we can also remove that use of
is_cpu_write_access. For calls of tb_invalidate_phys_page_range
that do not come from notdirty_mem_write, the next call to
notdirty_mem_write will notice that the page does not contain code
anymore, and will fix up the TLB entry.
The parameter needs to remain in order to guard accesses to cpu->mem_io_pc.

exec: use memory_region_get_dirty_log_mask to optimize dirty tracking
The memory API can now return the exact set of bitmaps that have to
be tracked. Use it instead of the in_migration variable.
In the next patches, we will also use it to set only DIRTY_MEMORY_VGA
or DIRTY_MEMORY_MIGRATION if necessary. This can make a difference
for dataplane, especially after the dirty bitmap is changed to use
more expensive atomic operations.
Of some interest is the change to stl_phys_notdirty. When migration
was introduced, stl_phys_notdirty was changed to effectively behave
as stl_phys during migration. In fact, if one looks at the function as it
was in the beginning (commit 8df1cd0, physical memory access functions,
2005-01-28), at the time the dirty bitmap was the equivalent of
DIRTY_MEMORY_CODE nowadays; hence, the function simply should not touch

Second, fix the second argument to the function in the
cpu_physical_memory_set_dirty_lebitmap call site. That function is only used
by KVM, but it is better to be clean anyway.

kvm: remove special handling of DIRTY_MEMORY_MIGRATION in the dirty log mask
One recent example is commit 4cc856f (kvm-all: Sync dirty-bitmap from
kvm before kvm destroy the corresponding dirty_bitmap, 2015-04-02).
Another performance problem is that KVM keeps tracking dirty pages
after a failed live migration, which causes bad performance due to
disallowing huge page mapping.
Thanks to the previous patch, KVM can now stop hooking into
log_global_start/stop. This simplifies the KVM code noticeably.

memory: include DIRTY_MEMORY_MIGRATION in the dirty log mask
The separate handling of DIRTY_MEMORY_MIGRATION, which does not
call log_start/log_stop callbacks when it changes in a region's
dirty logging mask, has caused several bugs.
One recent example is commit 4cc856f (kvm-all: Sync dirty-bitmap from
kvm before kvm destroy the corresponding dirty_bitmap, 2015-04-02).
Another performance problem is that KVM keeps tracking dirty pages
after a failed live migration, which causes bad performance due to
disallowing huge page mapping.
This patch removes the root cause of the problem by reporting
DIRTY_MEMORY_MIGRATION changes via log_start and log_stop.
Note that we now have to rebuild the FlatView when global dirty
logging is enabled or disabled; this ensures that log_start and
log_stop callbacks are invoked.
This will also be used to make the setting of bitmaps conditional.
In general, this patch lets users of the memory API ignore the
global state of dirty logging if they handle dirty logging
generically per region.

We could always treat updates as invalidations if dirty logging is

memory: prepare for multiple bits in the dirty log mask
When the dirty log mask will also cover other bits than DIRTY_MEMORY_VGA,
some listeners may be interested in the overall zero/non-zero value of
the dirty log mask; others may be interested in the value of single bits.
For this reason, always call log_start/log_stop if bits have respectively
appeared or disappeared, and pass the old and new values of the dirty log
mask so that listeners can distinguish the kinds of change.
For example, KVM checks if dirty logging used to be completely disabled
(in log_start) or is now completely disabled (in log_stop). On the
other hand, Xen has to check manually if DIRTY_MEMORY_VGA changed,
since that is the only bit it cares about.

memory: differentiate memory_region_is_logging and memory_region_get_dirty_log_mask
For now memory regions only track DIRTY_MEMORY_VGA individually, but
this will change soon. To support this, split memory_region_is_logging
in two functions: one that returns a given bit from dirty_log_mask,
and one that returns the entire mask. memory_region_is_logging gets an
extra parameter so that the compiler flags misuse.
While VGA-specific users (including the Xen listener!) will want to keep
checking that bit, KVM and vhost check for "any bit except migration"
(because migration is handled via the global start/stop listener
callbacks).

Makefile.target: set master BUILD_DIR
make can be invoked in the individual build dirs to build an individual
target or just a single file of a target. e.g.
touch translate-all.c
make -C microblazeel-softmmu translate-all.o
There is however a small bug when using the pixman submodule.
config-host.mak will ref BUILD_DIR for the pixman -I CFLAGS:
grep BUILD_DIR config-host.mak
QEMU_CFLAGS=-I$(SRC_PATH)/pixman/pixman -I$(BUILD_DIR)/pixman/pixman ...
This causes a build failure as -I/pixman/pixman (BUILD_DIR=="") will
not be found.
BUILD_DIR is usually set by the top level Makefile. Just lazy-set it in
Makefile.target to the parent directory.
Granted, this will not work if the pixman submodule is not prebuilt,
but it at least means you can do incremental partial builds once you
have done your initial full build (or attempt) from the top level.
The next step would be refactor make infrastructure to rebuild pixman
on a submake like the one above.

exec: optimize phys_page_set_level
phys_page_set_level is writing zeroes to a struct that has just been
filled in by phys_map_node_alloc. Instead, tell phys_map_node_alloc
whether to fill in the page "as a leaf" or "as a non-leaf".
memcpy is faster than struct assignment, which copies each bitfield
individually. A compiler bug (https://gcc.gnu.org/PR66391), and
small memcpys like this one are special-cased anyway, and optimized
to a register move, so just use the memcpy.
This cuts the cost of phys_page_set_level from 25% to 5% when
booting qboot.

ppc: add helpful message when KVM fails to start VCPU
On POWER8 systems, KVM checks if VCPU is running on primary threads,
and that secondary threads are offline. If this is not the case,
ioctl() fails with errno set to EBUSY.
QEMU aborts with a non explicit error message:
$ ./qemu-system-ppc64 --nographic -machine pseries,accel=kvm
error: kvm run failed Device or resource busy
To help user to diagnose the problem, this patch adds an informative
error message.
There is no easy way to check if SMT is enabled before starting the VCPU,
and as this case is the only one setting errno to EBUSY, we just check
the errno value to display a message.

target-s390x: fix MVC instruction when areas overlap
The MVC instruction and the memmove C funtion do not have the same
semantic when memory areas overlap:
MVC: When the operands overlap, the result is obtained as if the
operands were processed one byte at a time and each result byte were
stored immediately after fetching the necessary operand byte.
memmove: Copying takes place as though the bytes in src are first copied
into a temporary array that does not overlap src or dest, and the bytes
are then copied from the temporary array to dest.
The behaviour is therefore the same when the destination is at a lower
address than the source, but not in the other case. This is actually a
trick for propagating a value to an area. While the current code detects
that and call memset in that case, it only does for 1-byte value. This
trick can and is used for propagating two or more bytes to an area.
In the softmmu case, the call to mvc_fast_memmove is correct as the
above tests verify that source and destination are each within a page,
and both in a different page. The part doing the move 8 bytes by 8 bytes
is wrong and we need to check that if the source and destination
overlap, they do with a distance of minimum 8 bytes before copying 8
bytes at a time.
In the user code, we should check check that the destination is at a
lower address than source or than the end of the source is at a lower
address than the destination before calling memmove. In the opposite
case we fallback to the same code as the softmmu one. Note that l
represents (length - 1).

target-s390x: use softmmu functions for mvcp/mvcs
mvcp and mvcs helper get access to the physical memory by a call to
mmu_translate for the virtual to real conversion and then using ldb_phys
and stb_phys to physically access the data. In practice this is quite
slow because it bypasses the QEMU softmmu TLB and because stb_phys calls
try to invalidate the corresponding memory for each access.
Instead use cpu_ldb_{primary,secondary} for the loads and
cpu_stb_{primary,secondary} for the stores. Ideally this should be
further optimized by a call to memcpy, but that already improves the
boot time of a guest by a factor 1.8.

target-s390x: fix MMU index computation
The cpu_mmu_index function wrongly looks at PSW P bit to determine the
MMU index, while this bit actually only control the use of priviledge
instructions. The addressing mode is detected by looking at the PSW ASC
bits instead.
This used to work more or less correctly up to kernel 3.6 as the kernel
was running in primary space and userland in secondary space. Since
kernel 3.7 the default is to run the kernel in home space and userland
in primary space. While the current QEMU code seems to work it open some
security issues, like accessing the lowcore memory in R/W mode from a
userspace process once it has been accessed by the kernel (it is then
cached by the QEMU TLB).
At the same time change the MMU_USER_IDX value so that it matches the
value used in recent kernels.

target-s390x: fix LOAD MULTIPLE instruction on page boundary
When consecutive memory locations are on page boundary a page fault
might occur when using the LOAD MULTIPLE instruction. In that case real
hardware doesn't load any register.
This is an important detail in case the base register is in the list
of registers to be loaded. If a page fault occurs this register might be
overwritten and when the instruction is later restarted the wrong
base register value is useD.
Fix this by first loading the first and last value from memory, hence
triggering all possible page faults, and then the remaining registers.
This fixes random segmentation faults seen in the guest.

vhost: logs sharing
Currently we allocate one vhost log per vhost device. This is sub
optimal when:
- Guest has several device with vhost as backend
- Guest has multiqueue devices
In the above cases, we can avoid the memory allocation by sharing a
single vhost log among all the vhost devices. This is done through:
- Introducing a new vhost_log structure with refcnt inside.
- Using a global pointer to vhost_log structure that will be used. And
introduce helper to get the log with expected log size and helper to
- drop the refcnt to the old log.
- Each vhost device still keep track of a pointer to the log that was
used.
With above, if no resize happens, all vhost device will share a single
vhost log. During resize, a new vhost_log structure will be allocated
and made for the global pointer. And each vhost devices will drop the
refcnt to the old log.
Tested by doing scp during migration for a 2 queues virtio-net-pci.

hw/acpi: piix4_pm_init(): take fw_cfg object no more
This PIIX4 init function has no more reason to receive a pointer to the
FwCfg object. Remove the parameter from the prototype, and update callers.
As a result, the pc_init1() function no longer needs to save the return
value of pc_memory_init() and xen_load_linux(), which makes it more
similar to pc_q35_init().
The return type & value of pc_memory_init() and xen_load_linux() are not
changed themselves; maybe we'll need their return values sometime later.

hw/acpi: move "etc/system-states" fw_cfg file from PIIX4 to core
The acpi_pm1_cnt_init() core function is responsible for setting up the
register block that will ultimately react to S3 and S4 requests (see
acpi_pm1_cnt_write()). It makes sense to advertise this configuration to
the guest firmware via an easy to parse fw_cfg file (ACPI is too complex
for firmware to parse), and indeed PIIX4 does that. However, since
acpi_pm1_cnt_init() is not specific to PIIX4, neither should be the fw_cfg
file.
This patch makes "etc/system-states" appear on all chipsets modified in
the previous patch, not just PIIX4 (assuming they have fw_cfg at all).

Drop superfluous pc-dimm alignment on hot-pluggable mem

pseries: Enable in-kernel H_LOGICAL_CI_{LOAD, STORE} implementations
qemu currently implements the hypercalls H_LOGICAL_CI_LOAD and
H_LOGICAL_CI_STORE as PAPR extensions. These are used by the SLOF firmware
for IO, because performing cache inhibited MMIO accesses with the MMU off
(real mode) is very awkward on POWER.
This approach breaks when SLOF needs to access IO devices implemented
within KVM instead of in qemu. The simplest example would be virtio-blk
using an iothread, because the iothread / dataplane mechanism relies on
an in-kernel implementation of the virtio queue notification MMIO.
To fix this, an in-kernel implementation of these hypercalls has been made,
(kernel commit 99342cf "kvmppc: Implement H_LOGICAL_CI_{LOAD,STORE} in KVM"
however, the hypercalls still need to be enabled from qemu. This performs
the necessary calls to do so.
It would be nice to provide some warning if we encounter a problematic
device with a kernel which doesn't support the new calls. Unfortunately,
I can't see a way to detect this case which won't either warn in far too
many cases that will probably work, or which is horribly invasive.

spapr_events: event-scan RTAS interface
We don't actually rely on this interface to surface hotplug events, and
instead rely on the similar-but-interrupt-driven check-exception RTAS
interface used for EPOW events. However, the existence of this interface
is needed to ensure guest kernels initialize the event-reporting
interfaces which will in turn be used by userspace tools to handle these
events, so we implement this interface here.
Since events surfaced by this call are mutually exclusive to those
surfaced via check-exception, we also update the RTAS event queue code
to accept a boolean to mark/filter for events accordingly.
Events of this sort are not currently generated by QEMU, but the interface
has been tested by surfacing hotplug events via event-scan in place
of check-exception.

spapr_events: re-use EPOW event infrastructure for hotplug events
This extends the data structures currently used to report EPOW events to
guests via the check-exception RTAS interfaces to also include event types
for hotplug/unplug events.
This is currently undocumented and being finalized for inclusion in PAPR
specification, but we implement this here as an extension for guest
userspace tools to implement (existing guest kernels simply log these
events via a sysfs interface that's read by rtas_errd, and current
versions of rtas_errd/powerpc-utils already support the use of this
mechanism for initiating hotplug operations).
We also add support for queues of pending RTAS events, since in the
case of hotplug there's chance for multiple events being in-flight
at any point in time.

spapr_rtas: add ibm, configure-connector RTAS interface
This interface is used to fetch an OF device-tree nodes that describes a
newly-attached device to guest. It is called multiple times to walk the
device-tree node and fetch individual properties into a 'workarea'/buffer
provided by the guest.
The device-tree is generated by QEMU and passed to an sPAPRDRConnector during
the initial hotplug operation, and the state of these RTAS calls is tracked by
the sPAPRDRConnector. When the last of these properties is successfully
fetched, we report as special return value to the guest and transition
the device to a 'configured' state on the QEMU/DRC side.

this interface.

sensors. Initially, we only implement support necessary to control
sensors that are required for hotplug: DR connector indicators/LEDs,
resource allocation state, and resource isolation state.
See docs/specs/ppc-spapr-hotplug.txt for a complete description of
this interface.

spapr_rtas: add get/set-power-level RTAS interfaces
These interfaces manage the power domains that guest devices are
assigned to and are used to power on/off devices. Currently we
only utilize 1 power domain, the 'live-insertion' domain, which
automates power management of plugged/unplugged devices, essentially
making these calls no-ops, but the RTAS interfaces are still required
by guest hotplug code and PAPR+.
See docs/specs/ppc-spapr-hotplug.txt for a complete description of
these interfaces.

spapr_drc: initial implementation of sPAPRDRConnector device
This device emulates a firmware abstraction used by pSeries guests to
manage hotplug/dynamic-reconfiguration of host-bridges, PCI devices,
memory, and CPUs. It is conceptually similar to an SHPC device,
complete with LED indicators to identify individual slots to physical
physical users and indicate when it is safe to remove a device. In
some cases it is also used to manage virtualized resources, such a
memory, CPUs, and physical-host bridges, which in the case of pSeries
guests are virtualized resources where the physical components are
managed by the host.
Guests communicate with these DR Connectors using RTAS calls,
generally by addressing the unique DRC index associated with a
particular connector for a particular resource. For introspection
purposes we expose this state initially as QOM properties, and
in subsequent patches will introduce the RTAS calls that make use of
it. This constitutes to the 'guest' interface.
On the QEMU side we provide an attach/detach interface to associate
or cleanup a DeviceState with a particular sPAPRDRConnector in
response to hotplug/unplug, respectively. This constitutes the
'physical' interface to the DR Connector.

hw/ppc/spapr: Fix error message when firmware could not be loaded
When specifying a non-existing file with the "-bios" parameter, QEMU
complained that it "could not find LPAR rtas". That's obviously a
copy-n-paste bug from the code which loads the spapr-rtas.bin, it
should complain about a missing firmware file instead.
Additionally the error message was printed with hw_error() - which
also dumps the whole CPU state. However, this does not make much
sense here since the CPU is not running yet and thus the registers
only contain zeroes. So let's use error_report() here instead.
And while we're at it, let's also bail out if the firmware file
had zero length.

spapr_pci: Fix unsafe signed/unsigned comparisons
spapr_pci.c contains a number of expressions of the form (uval == -1) or
(uval != -1), where 'uval' is an unsigned value.
This mostly works in practice, because as long as the width of uval is
greater or equal than that of (int), the -1 will be promoted to the
unsigned type, which is the expected outcome.
However, at least for the cases where uval is uint32_t, this would break
on platforms where sizeof(int) > 4 (and a few such do exist), because then
the uint32_t value would be promoted to the larger int type, and never be
equal to -1.
This patch fixes these errors. The fixes for the (uint32_t) cases are
necessary as described above. I've made similar fixes to (uint64_t) and
(hwaddr) cases. Those are strictly theoretical, since I don't know of any
platforms where sizeof(int) > 8, but hey, it's not that hard so we might
as well be strictly C standard compliant.

hw/pci: introduce PCI Expander Bridge (PXB)
PXB is a "light-weight" host bridge whose purpose is to enable
the main host bridge to support multiple PCI root buses
for pc machines.
As oposed to PCI-2-PCI bridge's secondary bus, PXB's bus
is a primary bus and can be associated with a NUMA node
(different from the main host bridge) allowing the guest OS
to recognize the proximity of a pass-through device to
other resources as RAM and CPUs.
The PXB is composed from:
- A primary PCI bus (can be associated with a NUMA node)
Acts like a normal pci bus and from the functionality point
of view is an "expansion" of the bus behind the
main host bridge.
- A pci-2-pci bridge behind the primary PCI bus where the actual
devices will be attached.
- A host-bridge PCI device
Situated on the bus behind the main host bridge, allows
the BIOS to configure the bus number and IO/mem resources.
It does not have its own config/data register for configuration
cycles, this being handled by the main host bridge.
- A host-bridge sysbus to comply with QEMU current design.

hw/acpi: add support for i440fx 'snooping' root busses
If the machine has extra root busses that are snooping to
the i440fx host bridge, we need to add them to
acpi in order to be properly detected by guests.

s390x/kvm: always ignore empty vcpu interrupt state
kvm_s390_vcpu_interrupt_pre_save() and
kvm_s390_vcpu_interrupt_post_load() are essentially no-ops on hosts
without KVM_CAP_S390_IRQ_STATE. Move the capability check after the
check for saved IRQ state in kvm_s390_vcpu_interrupt_post_load() so that
migration between hosts without KVM_CAP_S390_IRQ_STATE (including save /
restore on the same host) continues to work.

virtio-ccw/migration: Migrate config vector for virtio devices
virtio_ccw_{save|load}_config are missing code to save and restore a vdev's
config_vector value. This causes some virtio devices to become disabled
following a migration.
This patch fixes a bug whereby the qmp/hmp balloon command (virsh setmem)
silently fails to update the guest's available memory because the device was not
properly migrated.
This will break compatibility, but vmstate_s390_cpu was bumped from
version 2 to version 4 between v2.3.0 and v2.4.0 without a compat
handler. Furthermore, there is no production environment yet so
migration is fenced anyway between any relevant version of 2.3 and 2.4.

util: socket: Add missing localaddr and localport option for DGRAM socket
The 'socket_optslist' structure does not contain the 'localaddr' and
'localport' options that are parsed in case you are creating a
'connect' type UDP character device.
I've noticed it happening after commit f43e47dbf6de24db20ec9b588bb6cc762
made qemu abort() after seeing the invalid option.
A minimal reproducer for the case is:
$ qemu-system-x86_64 -chardev udp,id=charrng0,host=127.0.0.1,port=1234,localaddr=,localport=1234
qemu-system-x86_64: -chardev udp,id=charrng0,host=127.0.0.1,port=1234,localaddr=,localport=1234: Invalid parameter 'localaddr'
Aborted (core dumped)
Prior to the commit mentioned above the error would be printed but the
value for localaddr and localport was simply ignored. I did not go
through the code to find out when it was broken.
Add the two fields so that the options can again be parsed correctly and
qemu doesn't abort().

pc: Ensure non-zero CPU ref count after attaching to ICC bus
Setting the parent bus of a device increases its ref count, which we
ultimately want to level out. However it is only safe to do so after the
last reference to the device in local code, as qom-set or similar operations
might decrease the ref count.
Therefore move the object_unref() from pc_new_cpu() into its callers.
The APIC operations on the last CPU in pc_cpus_init() are still potentially
insecure, but that is beyond the scope of this code movement.

fdc: Fix MSR.RQM flag
The RQM bit in MSR should be set whenever the guest is supposed to
access the FIFO, and it should be cleared in all other cases. This is
important so the guest can't continue writing/reading the FIFO beyond
the length that it's suppossed to access (see CVE-2015-3456).
Commit e9077462 fixed the CVE by adding code that avoids the buffer
overflow; however it doesn't correct the wrong behaviour of the floppy
controller which should already have cleared RQM.
Currently, RQM stays set all the time and during all phases while a
command is being processed. This is error-prone because the command has
to explicitly clear the flag if it doesn't need data (and indeed, the
two buggy commands that are the culprits for the CVE just forgot to do
that).
This patch clears RQM immediately as soon as all bytes that are expected
have been received. If the the FIFO is used in the next phase, the flag
has to be set explicitly there.
It also clear RQM after receiving all bytes even if the phase transition
immediately sets it again. While it's technically not necessary at the
moment because the state between clearing and setting RQM is not
observable by the guest, this is more explicit and matches how real
hardware works. It will actually become necessary in qemu once
asynchronous code paths are introduced.
This alone should have been enough to fix the CVE, but now we have two
lines of defense - even better.

hw/arm/virt: add dynamic sysbus device support
Allows sysbus devices to be instantiated from command line by
using -device option. Machvirt creates a platform bus at init.
The dynamic sysbus devices are attached to this platform bus device.
The platform bus device registers a machine init done notifier
whose role will be to bind the dynamic sysbus devices. Indeed
dynamic sysbus devices are created after machine init.
machvirt also registers a notifier that will build the device
tree nodes for the platform bus and its children dynamic sysbus
devices.

Device tree nodes for the platform bus and its children dynamic sysbus
devices are added in a machine init done notifier. To load the dtb once,
after those latter nodes are built and before ROM freeze, the actual
arm_load_kernel existing code is moved into a notifier notify function,
arm_load_kernel_notify. arm_load_kernel now only registers the
corresponding notifier.
Machine files that do not support platform bus stay unchanged. Machine
files willing to support dynamic sysbus devices must call arm_load_kernel
before sysbus-fdt arm_register_platform_bus_fdt_creator to make sure
dynamic sysbus device nodes are integrated in the dtb.

xen/pt: split out calculation of throughable mask in PCI config space handling
This is just to avoid having to adjust that calculation later in

Note that including ->ro_mask in get_throughable_mask()'s calculation
is only an apparent (i.e. benign) behavioral change: For r/o fields it
doesn't matter > whether they get passed through - either the same flag
is also set in emu_mask (then there's no change at all) or the field is
r/o in hardware (and hence a write won't change it anyway).

xen/MSI-X: limit error messages
Limit error messages resulting from bad guest behavior to avoid allowing
the guest to cause the control domain's disk to fill.
The first message in pci_msix_write() can simply be deleted, as this
is indeed bad guest behavior, but such out of bounds writes don't
really need to be logged.
The second one is more problematic, as there guest behavior may only
appear to be wrong: For one, the old logic didn't take the mask-all bit
into account. And then this shouldn't depend on host device state (i.e.
the host may have masked the entry without the guest having done so).
Plus these writes shouldn't be dropped even when an entry is unmasked.
Instead, if they can't be made take effect right away, they should take
effect on the next unmasking or enabling operation - the specification
explicitly describes such caching behavior. Until we can validly drop
the message (implementing such caching/latching behavior), issue the
message just once per MSI-X table entry.
Note that the log message in pci_msix_read() similar to the one being
removed here is not an issue: "addr" being of unsigned type, and the
maximum size of the MSI-X table being 32k, entry_nr simply can't be
negative and hence the conditonal guarding issuing of the message will
never be true.
This is XSA-130.

The old logic didn't work as intended when an access spanned multiple
fields (for example a 32-bit access to the location of the MSI Message
Data field with the high 16 bits not being covered by any known field).
Remove it and derive which fields not to write to from the accessed
fields' emulation masks: When they're all ones, there's no point in
doing any host write.
This fixes a secondary issue at once: We obviously shouldn't make any
host write attempt when already the host read failed.

arm_gicv2m: Add GICv2m widget to support MSIs
The ARM GICv2m widget is a little device that handles MSI interrupt
writes to a trigger register and ties them to a range of interrupt lines
wires to the GIC. It has a few status/id registers and the interrupt wires,
and that's about it.
A board instantiates the device by setting the base SPI number and
number SPIs for the frame. The base-spi parameter is indexed in the SPI
number space only, so base-spi == 0, means IRQ number 32. When a device
(the PCI host controller) writes to the trigger register, the payload is
the GIC IRQ number, so we have to subtract 32 from that and then index
into our frame of SPIs.
When instantiating a GICv2m device, tell PCI that we have instantiated
something that can deal with MSIs. We rely on the board actually wiring
up the GICv2m to the PCI host controller.

monitor: Use trad. command interface for HMP pcie_aer_inject_error
All QMP commands use the "new" handler interface (mhandler.cmd_new).
Most HMP commands still use the traditional interface (mhandler.cmd),
but a few use the "new" one. Complicates handle_user_command() for no
gain, so I'm converting these to the traditional interface.
pcie_aer_inject_error's implementation is split into the
hmp_pcie_aer_inject_error() and pcie_aer_inject_error_print(). The
former is a peculiar crossbreed between HMP and QMP handler. On
success, it works like a QMP handler: store QDict through ret_data
parameter, return 0. Printing the QDict is left to
pcie_aer_inject_error_print(). On failure, it works more like an HMP
handler: print error to monitor, return negative number.
To convert to the traditional interface, turn
pcie_aer_inject_error_print() into a command handler wrapping around
hmp_pcie_aer_inject_error(). By convention, this command handler
should be called hmp_pcie_aer_inject_error(), so rename the existing
hmp_pcie_aer_inject_error() to do_pcie_aer_inject_error().

monitor: Drop broken, unused asynchronous command interface
The asynchronous monitor command interface goes back to commit 940cc30
(Jan 2010). Added a third case to command execution. The hope back
then according to the commit message was that all commands get
converted to the asynchronous interface, killing off the other two
cases. Didn't happen.
The initial asynchronous commands balloon and info balloon were
converted back to synchronous long ago (commit 96637bc and d72f32),
with commit messages calling the asynchronous interface "not fully
working" and "deprecated". The only other user went away in commit
3b5704b.
New code generally uses synchronous commands and asynchronous events.
What exactly is still "not fully working" with asynchronous commands?
Well, here's a bug that defeats actual asynchronous use pretty
reliably: the reply's ID is wrong (and has always been wrong) unless
you use the command synchronously! To reproduce, we need an
asynchronous command, so we have to go back before commit 3b5704b.
Run QEMU with spice:
$ qemu-system-x86_64 -nodefaults -S -spice port=5900,disable-ticketing -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 94, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}}
Connect a spice client in another terminal:
$ remote-viewer spice://localhost:5900
Set up a migration destination dummy in a third terminal:
$ socat TCP-LISTEN:12345 STDIO
Now paste the following into the QMP monitor:
{ "execute": "qmp_capabilities", "id": "i0" }
{ "execute": "client_migrate_info", "id": "i1", "arguments": { "protocol": "spice", "hostname": "localhost", "port": 12345 } }
{ "execute": "query-kvm", "id": "i2" }
Produces two replies immediately, one to qmp_capabilities, and one to
query-kvm:
{"return": {}, "id": "i0"}
{"return": {"enabled": false, "present": true}, "id": "i2"}
Both are correct. Two lines of debug output from libspice-server not
shown.
Now EOF socat's standard input to make it close the connection. This
makes the asynchronous client_migrate_info complete. It replies:
{"return": {}}
Bug: "id": "i1" is missing. Two lines of debug output from
libspice-server not shown. Cherry on top: storage for the missing ID
is leaked.
Get rid of this stuff before somebody hurts himself with it.

virtio: make features 64bit wide
Make features 64bit wide everywhere.
On migration a full 64bit guest_features field is sent if one of the
high bits is set, in addition to the lower 32bit guest_features field
which must stay for compatibility reasons. That way we send the lower
32 feature bits twice, but the code is simpler because we don't have
to split and compose the 64bit features into two 32bit fields.

virtio-mmio: ioeventfd support
set_host_notifier and set_guest_notifiers supported by virtio-mmio now.
Most code copied from virtio-pci.
This makes it possible to use vhost-net with virtio-mmio,
improving performance by about 30%.
The kvm-arm does not yet support irqfd, need to fix the hard-coded part after
kvm-arm gets irqfd support.

Extend TPM TIS interface to support TPM 2
Following the recent upgrade to version 1.3, extend the TPM TIS
interface with capabilities introduced for support of a TPM 2.
TPM TIS for TPM 2 introduced the following extensions beyond the
TPM TIS 1.3 (used for TPM 1.2):
- A new 32bit interface Id register was introduced.
- New flags for the status (STS) register were defined.
- New flags for the capability flags were defined.
Support the above if a TPM TIS 1.3 for TPM 2 is used with a TPM 2
on the backend side. Support the old TPM TIS 1.3 configuration if a
TPM 1.2 is being used. A subsequent patch will then determine which
TPM version is being used in the backend.

i386: drop FDC in pc-q35-2.4+ if neither it nor floppy drives are wanted
It is Very annoying to carry forward an outdatEd coNtroller with a mOdern
Machine type.
Hence, let us not instantiate the FDC when all of the following apply:
- the machine type is pc-q35-2.4 or later,
- "-device isa-fdc" is not passed on the command line (nor in the config
file),
- no "-drive if=floppy,..." is requested.

i386/pc_q35: don't insist on board FDC if there's no default floppy
The "no_floppy = 1" machine class setting causes "default_floppy" in
main() to become zero. Consequently, default_drive() will not call
drive_add() and drive_new() for IF_FLOPPY, index=0, meaning that no
default floppy drive will be created for the virtual machine. In that
case, board code should also not insist on the creation of the
board-default FDC.
The board-default FDC will still be created if the user requests a floppy
drive with "-drive if=floppy".
Additionally, separate FDCs can be specified manually with "-device
isa-fdc". They allow the
-device isa-fdc,driveA=...
syntax that is more flexible than the one required by the board-default
FDC:
-global isa-fdc.driveA=...
This patch doesn't change the behavior observably, as all Q35 machine
types have "no_floppy = 0".

i386/pc: '-drive if=floppy' should imply a board-default FDC
Even if board code decides not to request the creation of the FDC (keyed
off board-level factors, to be determined later), we should create the FDC
nevertheless if the user passes '-drive if=floppy' on the command line.
Otherwise '-drive if=floppy' would break without explicit '-device
isa-fdc' on such boards.

i386/pc: pc_basic_device_init(): delegate FDC creation request
This patch introduces no observable change, but it allows the callers of
pc_basic_device_init(), ie. pc_init1() and pc_q35_init(), to request (or
not request) the creation of the FDC explicitly.
At the moment both callers pass constant create_fdctrl=true (hence no
observable change).
Assuming a board passes create_fdctrl=false, "floppy" will be NULL on
output, and (beyond the FDC not being created) that NULL will be passed on
to pc_cmos_init(). Luckily, pc_cmos_init() already handles that case.

virtio: move host_features
Move host_features from the individual transport proxies into
the virtio device. Transports may continue to add feature bits
during device plugging.
This should it make easier to offer different sets of host features
for virtio-1/transitional support.

pc: acpi: fix pvpanic for buggy guests
In the old times, we always had pvpanic in ACPI and a _STA method told
the guest not to use it. Automatic generation dropped the _STA method
as the specification says that missing _STA means enabled and working.
Some guests (Linux) had buggy drivers and this change made them unable
to utilize pvpanic.
A Linux patch is posted as well, but I think it's worth to make pvpanic
useable on old guests at the price of three lines and few bytes of SSDT.
The old _STA method was
Method (_STA, 0, NotSerialized) {
Store (PEST, Local0)
If (LEqual (Local0, Zero)) {
Return (Zero) }
Else {
Return (0x0F) }}
Igor pointed out that we don't need to use a method to return a constant
and that 0xB (don't show in UI) is the common definition now.
Also, the device used to be PEVT. (PEVT as in "panic event"?)

pc: Define MACHINE_OPTIONS macros consistently for all machines
Define a MACHINE_OPTIONS macro for each PC machine, and move every field
inside the QEMUMachine structs to the macros, except for name, init, and
compat_props.
This also ensures that all MACHINE_OPTIONS inherit the fields from the
next version, so their definitions carry only the changes that exist
between one version and the next one.
Comments about specific cases:
pc-*-2.1:
Existing PC_*_2_1_MACHINE_OPTIONS macros were defined as:
PC_*_MACHINE_OPTIONS,
.default_machine_opts = "firmware=bios-256k.bin"
PC_*_2_2_MACHINE_OPTIONS is:
PC_*_2_3_MACHINE_OPTIONS
which is expanded to:
PC_*_MACHINE_OPTIONS,
.default_machine_opts = "firmware=bios-256k.bin",
.default_display = "std"
The only difference between 2_1 and 2_2 is .default_display, that's why
we didn't reuse PC_*_2_2_MACHINE_OPTIONS. The good news is that having
multiple initializers for a field is allowed by C99, and the last
initializer overrides the previous ones.
So we can reuse the 2_2 macro in 2_1 and define PC_*_2_1_MACHINE_OPTIONS
as:
PC_*_2_2_MACHINE_OPTIONS,
.default_display = NULL
pc-*-1.7:
PC_*_1_7_MACHINE_OPTIONS was defined as:
PC_*_MACHINE_OPTIONS
PC_*_2_0_MACHINE_OPTIONS is defined as:
PC_*_2_1_MACHINE_OPTIONS
which is expanded to:
PC_*_2_2_MACHINE_OPTIONS,
.default_display = NULL
which is expanded to:
PC_*_2_3_MACHINE_OPTIONS,
.default_display = NULL
which is expanded to:
PC_*_MACHINE_OPTIONS,
.default_machine_opts = "firmware=bios-256k.bin",
.default_display = "std",
.default_display = NULL /* overrides the previous line */
So, the only difference between PC_*_1_7_MACHINE_OPTIONS and
PC_*_2_0_MACHINE_OPTIONS is .default_machine_opts (as .default_display
is not explicitly set by PC_*_MACHINE_OPTIONS so it is NULL).
So we can keep the macro reuse pattern and define
PC_*_2_0_MACHINE_OPTIONS as:
PC_*_2_0_MACHINE_OPTIONS,
.default_machine_opts = NULL
pc-*-2.4 (alias and is_default fields):
Set alias and is_default fields inside the 2.4 MACHINE_OPTIONS macro,
and clear it in the 2.3 macro (that reuses the 2.4 macro).
hw_machine:
As all the machines older than v1.0 set hw_version explicitly, we can
safely move the field to the MACHINE_OPTIONS macros without affecting
the other versions that reuse them.
init function:
Some machines had the init function set inside the MACHINE_OPTIONS
macro. Move it to the QEMUMachine declaration, to keep it consistent
with the other machines.

The new variables will now be inherited by pc-0.11 and older, but
pc-0.11 and pc-0.10 already have PCI.rombar=0 on compat_props, so they

commit 9abe3bdc45ced367fe034c0fdd7c686212389767
Author: John Snow <jsnow@redhat.com>

qapi: add dirty bitmap status
Bitmaps can be in a handful of different states with potentially
more to come as we tool around with migration and persistence patches.
Management applications may need to know why certain bitmaps are
unavailable for various commands, e.g. busy in another operation,
busy being migrated, etc.
Right now, all we offer is BlockDirtyInfo's boolean member 'frozen'.
Instead of adding more booleans, replace it by an enumeration member
'status' with values 'active' and 'frozen'. Then add new value
'disabled'.
Incompatible change. Fine because the changed part hasn't been
released so far.

target-arm: Avoid buffer overrun on UNPREDICTABLE ldrd/strd
A LDRD or STRD where rd is not an even number is UNPREDICTABLE.
We were letting this fall through, which is OK unless rd is 15,
in which case we would attempt to do a load_reg or store_reg
to a nonexistent r16 for the second half of the double-word.
Catch the odd-numbered-rd cases and UNDEF them instead.
To do this we rearrange the structure of the code a little
so we can put the UNDEF catches at the top before we've
allocated TCG temporaries.

Introduce a preliminary framework in virt-acpi-build.c with the main
ACPI build functions. It exposes the generated ACPI contents to
guest over fw_cfg.
The required ACPI v5.1 tables for ARM are:
- RSDP: Initial table that points to XSDT
- RSDT: Points to FADT GTDT MADT tables
- FADT: Generic information about the machine
- GTDT: Generic timer description table
- MADT: Multiple APIC description table
- DSDT: Holds all information about system devices/peripherals, pointed by FADT

target-arm: Don't halt on WFI unless we don't have any work
Just NOP the WFI instruction if we have work to do.
This doesn't make much difference currently (though it does avoid
jumping out to the top level loop and immediately restarting),
but the distinction between "halt" and "don't halt" will become
more important when the decision to halt requires us to trap
to a higher exception level instead.

kbd: add brazil kbd keys to qemu
The brazilian computer keyboard layout has two extra keys (compared to
the usual 105-key intl ps/2 keyboard). This patch makes these two keys
known to qemu.
For historic reasons qemu has two ways to specify a key: A QKeyCode
(name-based) or a number (ps/2 scancode based). Therefore we have to
update multiple places to make new keys known to qemu:
(1) The QKeyCode definition in qapi-schema.json
(2) The QKeyCode <-> number mapping table in ui/input-keymap.c
This patch does just that. With this patch applied you can send those
two keys to the guest using the send-key monitor command.

s390x: Migrate vector registers
When migrating a guest, be sure to include the vector registers.
The vector registers are defined in a subsection, similar to the
existing subsection for floating point registers. Since the
floating point registers are always present (and thus migrated),
we can skip them when performing the migration of the vector
registers which may or may not be present.

Handle the actual syncing of the vector registers with kernel space,
via the get/put register IOCTLs.
The vector registers that were introduced with the z13 overlay
the existing floating point registers. FP registers 0-15 are
the high-halves of vector registers 0-15. Thus, remove the
freg fields and replace them with the equivalent vector field
to avoid errors in duplication. Moreover, synchronize either the
vector registers via kvm_sync_regs, or floating point registers
via the GET/SET FPU IOCTLs.

net/net: Record usage status of mac address
Currently QEMU dynamically generates mac address for the NIC which
doesn't specify the mac address. But when we hotplug a NIC without
specifying mac address, the mac address will increase for the same NIC
along with hotplug and hot-unplug, and at last it will overflow. And if
we codeplug one NIC with mac address e.g. "52:54:00:12:34:56", then
hotplug one NIC without specifying mac address and the mac address of
the hotplugged NIC is duplicate of "52:54:00:12:34:56".
This patch add a mac_table to record the usage status and free the mac
address when the NIC is unrealized.

tap: Improve -netdev/netdev_add/-net/... tap error reporting
When -netdev tap fails, it first reports a specific error, then a
generic one, like this:
$ qemu-system-x86_64 -netdev tap,id=foo
qemu-system-x86_64: -netdev tap,id=foo: could not configure /dev/net/tun: Operation not permitted
qemu-system-x86_64: -netdev tap,id=foo: Device 'tap' could not be initialized
With the command line, the messages go to stderr. In HMP, they go to
the monitor. In QMP, the second one becomes the error reply, and the
first one goes to stderr.
Convert net_init_tap() to Error. This suppresses the unwanted second
message, and makes the specific error the QMP error reply.
[Dropped duplicate "and" from error message as suggested by Eric Blake:

tap: Improve -netdev/netdev_add/-net/... bridge error reporting
When -netdev bridge fails, it first reports a specific error, then a
generic one, like this:
$ qemu-system-x86_64 -netdev bridge,id=foo
failed to launch bridge helper
qemu-system-x86_64: -netdev bridge,id=foo: Device 'bridge' could not be initialized
The first message goes to stderr. Wrong for HMP, because errors need
to go to the monitor there.
The second message goes to stderr for -netdev, to the monitor for HMP
netdev_add, and becomes the error reply for QMP netdev_add.
Convert net_bridge_run_helper() to Error, and propagate its errors
through net_init_bridge(). This ensures the error gets reported where
the user is, and suppresses the unwanted second message.
While there, improve the error messages a bit.
The above example becomes:
$ qemu-system-x86_64 -netdev bridge,id=foo
qemu-system-x86_64: -netdev bridge,id=foo: bridge helper failed
net_init_tap() also uses net_bridge_run_helper(). Propagate its
errors there as well. Improves reporting these errors with -netdev
tap & friends.

net: Permit incremental conversion of init functions to Error
Error reporting for netdev_add is broken: the net_client_init_fun[]
report the actual errors with (at best) error_report(), and their
caller net_client_init1() makes up a generic error on top.
For command line and HMP, this produces an mildly ugly error cascade.
In QMP, the actual errors go to stderr, and the generic error becomes
the command's error reply.
To fix this, we need to convert the net_client_init_fun[] to Error.
To permit fixing them one by one, add an Error ** parameter to the
net_client_init_fun[]. If the call fails without returning an Error,
make up the same generic Error as before. But if it returns one, use
that instead. Since none of them does so far, no functional change.

net: Change help text to list -netdev instead of -net by default
Looking at the output of "qemu-system-xxx -help", you easily get
the impression that "-net" is the preferred way instead of "-netdev"
to specify host network interface, since the "-net" option is
omnipresent but the "-netdev" option is only listed as a one-liner
at the end. This is ugly since "-net" is considered as legacy and
even might be removed one day. Thus, this patch switches the output
to explain the host network interfaces with the "-netdev" option
instead, moving the old "-net" option into some few lines at
the end.

ahci: do not remap clb/fis unconditionally
This continues the IOMMU fix from 2.3, where we should not attempt
to remap the CLB or FIS RX buffers if the AHCI device is currently
running.
The same applies to migration: keep our mitts off these registers
unless the device is supposed to be on.
Does not impact backwards compatibility for the AHCI device.

qtest: pre-buffer hex nibs
Instead of converting each byte one-at-a-time and then sending each byte
over the wire, use sprintf() to pre-compute all of the hex nibs into a
single buffer, then send the entire buffer all at once.
This gives a moderate speed boost to memread() and memwrite() functions.

qtest: Add base64 encoded read/write
For larger pieces of data that won't need to be debugged and
viewing the hex nibbles is unlikely to be useful, we can encode
data using base64 instead of encoding each byte as %02x, which
leads to some space savings and faster reads/writes.
For now, the default is left as hex nibbles in memwrite() and memread().
For the purposes of making qtest io easier to read and debug, some
callers may want to specify using the old encoding format for small
patches of data where the savings from base64 wouldn't be that profound.
memwrite/memread use a data encoding that takes 2x the size of the original
buffer, but base64 uses "only" (4/3)x, so for larger buffers we can save a
decent amount of time and space.

qtest: allow arbitrarily long sends
qtest currently has a static buffer of size 1024 that if we
overflow, ignores the additional data silently which leads
to hangs or stream failures.
Use glib's string facilities to allow arbitrarily long data,
but split this off into a new function, qtest_sendf.
Static data can still be sent using qtest_send, which avoids
the malloc/copy overhead.

qtest/ahci: Add migration test
Notes:
* The migration is performed on QOSState objects.
* The migration is performed in such a way that it does not assume
consistency between the allocators attached to each. That is to say,
you can use each QOSState object completely independently and then at
an arbitrary point decide to migrate, and the destination object will
now be consistent with the memory within the source guest. The source
object that was migrated from will have a completely blank allocator.
ahci-test.c:
- verify_state is added
- ahci_migrate is added as a frontend to migrate
- test_migrate_sanity test case is added.

qcow2/qcow: protect against uninitialized encryption key
When a qcow[2] file is opened, if the header reports an
encryption method, this is used to set the 'crypt_method_header'
field on the BDRVQcow[2]State struct, and the 'encrypted' flag
in the BDRVState struct.
When doing I/O operations, the 'crypt_method' field on the
BDRVQcow[2]State struct is checked to determine if encryption
needs to be applied.
The crypt_method_header value is copied into crypt_method when
the bdrv_set_key() method is called.
The QEMU code which opens a block device is expected to always
do a check
if (bdrv_is_encrypted(bs)) {
bdrv_set_key(bs, ....key...);
}
If code forgets to do this, then 'crypt_method' is never set
and so when I/O is performed, QEMU writes plain text data
into a sector which is expected to contain cipher text, or
when reading, will return cipher text instead of plain
text.
Change the qcow[2] code to consult bs->encrypted when deciding
whether encryption is required, and assert(s->crypt_method)
to protect against cases where the caller forgets to set the
encryption key.
Also put an assert in the set_key methods to protect against
the case where the caller sets an encryption key on a block
device that does not have encryption

qemu-iotests: Make debugging python tests easier
Adding "-d" option. The output goes to "tee" so it appears in your
console. Also, raise the verbosity of unnitest runner.
When testing a topic branch, it's possible that a bug introduced by a
code change makes the python test case hang, with debug output, it is
much easier to locate the problem.
This can also be helpful if you want to watch the progress of a python
test, it offers you a way to sense the speed of each test case method
you're writing.
Note: because there is no easy way to get *both* the verbose output and
the output expected by ./check comparison, the case would always fail
with an "output mismatch". The sole purpose of using this option is
giving developers a quick way to debug when things go wrong.

qemu-io: Use getopt() correctly
POSIX says getopt() returns -1 on completion. While Linux happens
to define EOF as -1, this definition is not required by POSIX, and
there may be platforms where checking for EOF instead of -1 would
lead to an infinite loop.

qcow2: use a hash to look for entries in the L2 cache
The current cache algorithm traverses the array starting always from
the beginning, so the average number of comparisons needed to perform
a lookup is proportional to the size of the array.
By using a hash of the offset as the starting point, lookups are
faster and independent from the array size.
The hash is computed using the cluster number of the table, multiplied
by 4 to make it perform better when there are collisions.
In my tests, using a cache with 2048 entries, this reduces the average
number of comparisons per lookup from 430 to 2.5.

qcow2: use an LRU algorithm to replace entries from the L2 cache
The current algorithm to evict entries from the cache gives always
preference to those in the lowest positions. As the size of the cache
increases, the chances of the later elements of being removed decrease
exponentially.
In a scenario with random I/O and lots of cache misses, entries in
positions 8 and higher are rarely (if ever) evicted. This can be seen
even with the default cache size, but with larger caches the problem
becomes more obvious.
Using an LRU algorithm makes the chances of being removed from the
cache independent from the position.

qcow2: use one single memory block for the L2/refcount cache tables
The qcow2 L2/refcount cache contains one separate table for each cache
entry. Doing one allocation per table adds unnecessary overhead and it
also requires us to store the address of each table separately.
Since the size of the cache is constant during its lifetime, it's
better to have an array that contains all the tables using one single
allocation.
In my tests measuring freshly created caches with sizes 128MB (L2) and
32MB (refcount) this uses around 10MB of RAM less.

vmdk: Fix overflow if l1_size is 0x20000000
Richard Jones caught this bug with afl fuzzer.
In fact, that's the only possible value to overflow (extent->l1_size =
0x20000000) l1_size:
l1_size = extent->l1_size * sizeof(long) => 0x80000000;
g_try_malloc returns NULL because l1_size is interpreted as negative
during type casting from 'int' to 'gsize', which yields a enormous
value. Hence, by coincidence, we get a "not too bad" behavior:
qemu-img: Could not open '/tmp/afl6.img': Could not open
'/tmp/afl6.img': Cannot allocate memory
Values larger than 0x20000000 will be refused by the validation in
vmdk_add_extent.
Values smaller than 0x20000000 will not overflow l1_size.

qcow2: Flush pending discards before allocating cluster
Before a freed cluster can be reused, pending discards for this cluster
must be processed.
The original assumption was that this was not a problem because discards
are only cached during discard/write zeroes operations, which are
synchronous so that no concurrent write requests can cause cluster
allocations.
However, the discard/write zeroes operation itself can allocate a new L2
table (and it has to in order to put zero flags there), so make sure we
can cope with the situation.
This fixes https://bugs.launchpad.net/bugs/1349972.

Commit fc3959e466 fixed bdrv_co_write_zeroes which is the common case
for this bug, but it still exists in bdrv_aio_write_zeroes. A simpler
fix would be in bdrv_co_do_pwritev which is the NULL dereference point
and covers both cases.
So don't access it in bdrv_co_do_pwritev in this case, use three aligned
writes.

block: align bounce buffers to page
The following sequence
int fd = open(argv[1], O_RDWR | O_CREAT | O_DIRECT, 0644);
for (i = 0; i < 100000; i++)
write(fd, buf, 4096);
performs 5% better if buf is aligned to 4096 bytes.
The difference is quite reliable.
On the other hand we do not want at the moment to enforce bounce
buffering if guest request is aligned to 512 bytes.
The patch changes default bounce buffer optimal alignment to
MAX(page size, 4k). 4k is chosen as maximal known sector size on real
HDD.
The justification of the performance improve is quite interesting.
From the kernel point of view each request to the disk was split
by two. This could be seen by blktrace like this:

block: minimal bounce buffer alignment
The patch introduces new concept: minimal memory alignment for bounce
buffers. Original so called "optimal" value is actually minimal required
value for aligment. It should be used for validation that the IOVec
is properly aligned and bounce buffer is not required.
Though, from the performance point of view, it would be better if
bounce buffer or IOVec allocated by QEMU will be aligned stricter.
The patch does not change any alignment value yet.

block: return EPERM on writes or discards to read-only devices
This is the behavior in the operating system, for example Linux's
blkdev_write_iter has the following:
if (bdev_read_only(I_BDEV(bd_inode)))
return -EPERM;
This does not apply to opening a device for read/write, when the
device only supports read-only operation. In this case any of
EACCES, EPERM or EROFS is acceptable depending on why writing is
not possible.

configure: Add workaround for ccache and clang
Test if ccache is interfering with semantic analysis of macros,
disable its habit of trying to compile already pre-processed
versions of code if so. ccache attempts to save time by compiling
pre-processed versions of code, but this disturbs clang's static
analysis enough to produce false positives.
ccache allows us to disable this feature, opting instead to
compile the original version instead of its preprocessed version.
This makes ccache much slower for cache misses, but at least it
becomes usable with QEMU/clang.
This workaround only activates for users using ccache AND clang,
and only if their configuration is observed to be producing warnings.
You may need to clear your ccache for builds started without -Werror,
as those may continue to produce warnings from the cache.
Thanks to Peter Eisentraut for his writeup on the issue:

doesn't support the same attributes as GCC.
clang 3.5.0 does not support the __alloc_size__ attribute:
https://github.com/llvm-mirror/clang/commit/c047507a9a79e89fc8339e074fa72822a7e7ea73
The following warning is produced:

gmacros.h:67:45: note: expanded from macro 'G_GNUC_ALLOC_SIZE'

block/parallels: optimize linear image expansion
Plain image expansion spends a lot of time to update image file size.
This seriously affects the performance. The following simple test
qemu_img create -f parallels -o cluster_size=64k ./1.hds 64G
qemu_io -n -c "write -P 0x11 0 1024M" ./1.hds
could be improved if the format driver will pre-allocate some space
in the image file with a reasonable chunk.
This patch preallocates 128 Mb using bdrv_write_zeroes, which should
normally use fallocate() call inside. Fallback to older truncate()
could be used as a fallback using image open options thanks to the
previous patch.
The benefit is around 15%.

block/parallels: add prealloc-mode and prealloc-size open paramemets
This is preparational commit for tweaks in Parallels image expansion.
The idea is that enlarge via truncate by one data block is slow. It
would be much better to use fallocate via bdrv_write_zeroes and
expand by some significant amount at once.
Original idea with sequential file writing to the end of the file without
fallocate/truncate would be slower than this approach if the image is
expanded with several operations:
- each image expanding means file metadata update, i.e. filesystem
journal write. Truncate/write to newly truncated space update file
metadata twice thus truncate removal helps. With fallocate call
inside bdrv_write_zeroes file metadata is updated only once and
this should happen infrequently thus this approach is the best one
for the image expansion
- tail writes are ordered, i.e. the guest IO queue could not be sent
immediately to the host introducing additional IO delays
This patch just adds proper parameters into BDRVParallelsState and
performs options parsing in parallels_open.

block/parallels: delay writing to BAT till bdrv_co_flush_to_os
The idea is that we do not need to immediately sync BAT to the image as
from the guest point of view there is a possibility that IO is lost
even in the physical controller until flush command was finished.
bdrv_co_flush_to_os is exactly the right place for this purpose.
Technically the patch uses loaded BAT data as a cache and performs
actual on-disk metadata updates in parallels_co_flush_to_os callback.
This patch speed ups
qemu-img create -f parallels -o cluster_size=64k ./1.hds 64G
qemu-io -f parallels -c "write -P 0x11 0 1024k" 1.hds
writing from 50-60 Mb/sec to 80-90 Mb/sec on rotational media and
from 160 Mb/sec to 190 Mb/sec on SSD disk.

block/parallels: implement incorrect close detection
The software driver must set inuse field in Parallels header to
0x746F6E59 when the image is opened in read-write mode. The presence of
this magic in the header on open forces image consistency check.
There is an unfortunate trick here. We can not check for inuse in
parallels_check as this will happen too late. It is possible to do
that for simple check, but during the fix this would always report
an error as the image was opened in BDRV_O_RDWR mode. Thus we save
the flag in BDRVParallelsState for this.
On the other hand, nothing should be done to clear inuse in
parallels_check. Generic close will do the job right.

block/parallels: provide _co_readv routine for parallels format driver
Main approach is taken from qcow2_co_readv.
The patch drops coroutine lock for the duration of IO operation and
peforms normal scatter-gather IO using standard QEMU backend.
The patch also adds comment about locking considerations in the driver.

$ ls -l ~/root-owned/foo.sock

...which is techinically true, but the real error is that we failed to
unlink. So report it.

serial: fix multi-pci card error cleanup.
Put the number of serial ports into a local variable in
multi_serial_pci_realize, then increment the port count
(pci->ports) as we initialize the serial port cores.
Now pci->ports always holds the number of successfully
initialized ports and we can use multi_serial_pci_exit
to properly cleanup the already initialized bits in case
of a init failure.

ui/cocoa: Avoid deprecated NSOKButton/NSCancelButton constants
In OSX 10.10, the NSOKButton and NSCancelButton constants are deprecated
and provoke compiler warnings. Avoid them by using the
NSFileHandlingPanelCancelButton and NSFileHandlingPanelOKButton constants
instead. These are the documented correct constants for the 10.6-and-up
beginSheetModalForWindow API we use. We also use the same method for
the pre-10.6 compatibility code path, but conveniently the constant
values are the same and the constant names have been present since 10.0.
Preferring the constant names that match the non-legacy API makes more
sense anyway.

ui/cocoa: Declare that QemuCocoaAppController implements NSApplicationDelegate
Our class QemuCocoaAppController implements the NSApplicationDelegate
interface, and we pass an object of this class to [NSApp setDelegate].
However, we weren't declaring in the class definition that we implemented
this interface; in OSX 10.10 this provokes the following (slighly
misleading) warning:
ui/cocoa.m:1031:24: warning: sending 'QemuCocoaAppController *' to parameter of
incompatible type 'id<NSFileManagerDelegate>'
[NSApp setDelegate:appController];
^~~~~~~~~~~~~
/System/Library/Frameworks/Foundation.framework/Headers/NSFileManager.h:109:47:
note: passing argument to parameter 'delegate' here
@property (assign) id <NSFileManagerDelegate> delegate NS_AVAILABLE(10_5,
2_0);
^
Annoyingly, this interface wasn't formally defined until OSX 10.6, so we
have to surround the relevant part of the @interface line with an ifdef.

ui/cocoa: Drop tests for CGImageCreateWithImageInRect support
The code that tries to test at both compiletime and runtime
for whether CGImageCreateWithImageInRect is supported provokes
a compile warning on OSX 10.3:
ui/cocoa.m:378:13: warning: comparison of function 'CGImageCreateWithImageInRect'
equal to a null pointer is always false[-Wtautological-pointer-compare]
if (CGImageCreateWithImageInRect == NULL) { // test if "CGImageCreateWithImageInRect" is
supported on host at runtime
^~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~
The simplest way to deal with this is just to drop this code,
since we don't in practice support OSX 10.4 anyway. (10.5 was
released in 2007 and is the last PPC version, so is the earliest
we really need to continue to support at all.)

ui/cocoa: Fix several full screen issues on Mac OS X
This patch makes several changes:
- Minimizes distorted full screen display by respecting aspect
ratios.
- Makes full screen mode available on Mac OS 10.7 and higher.
- Allows user to decide if video should be stretched to fill the
screen, using a menu item called "Zoom To Fit".
- Hides the normalWindow so it won't show up in full screen mode.
- Allows user to exit full screen mode.

Clean up some variable names in preparation for migrating the state struct

not specific enough to be used in a more global namespace so preface with
"cadence". Fix the capitalisation of "uart" in the state type while touching
the typename. Preface macros used by the state struct itself with CADENCE_UART
so they don't conflict in namespace either.

net: cadence_gem: Clean up variable names
Cleanup some variable names in preparation for migrating the state
struct and type cast macro to a public header. The acronym "GEM" on
its own is not specific enough to be used in a more global namespace
so preface with "cadence". Fix the capitalisation of "gem" in the
state type while touching the typename. Also preface the GEM_MAXREG
macro as this will need to migrate to public header.

Anything but --type sync (which is the default) suppresses output

Dates back to the initial commit c17d990. Commit message says
"Currently only generators for synchronous qapi/qmp functions are
supported", so maybe output other than "synchronous qapi/qmp" was
planned at the time, to be selected with --type.
Should other kinds of output ever materialize, we can put the option
back.

qapi: Make c_type() consistently convert qapi names
Continuing the string of cleanups for supporting downstream names
containing '.', this patch focuses on ensuring c_type() can
handle a downstream name. This patch alone does not fix the
places where generator output should be calling this function
but was open-coding things instead, but it gets us a step closer.
In particular, the changes to c_list_type() and type_name() mean
that type_name(FOO) now handles the case when FOO contains '.',
'-', or is a ticklish identifier other than a builtin (builtins
are exempted because ['int'] must remain mapped to 'intList' and
not 'q_intList'). Meanwhile, ['unix'] now maps to 'q_unixList'
rather than 'unixList', to match the fact that 'unix' is ticklish;
however, our naming conventions state that complex types should
start with a capital, so no type name following conventions will
ever have the 'q_' prepended.
Likewise, changes to c_type() mean that c_type(FOO) properly
handles an enum or complex type FOO with '.' or '-' in the
name, or is a ticklish identifier (again, a ticklish identifier
as a type name violates conventions).

qapi: Tidy c_type() logic
c_type() is designed to be called on both string names and on
array designations, so 'name' is a bit misleading because it
operates on more than strings. Also, no caller ever passes
an empty string. Finally, + notation is a bit nicer to read
than '%s' % value for string concatenation.

Now that the two functions are identical, we only need one of them,

the function serves as the translation from a QAPI name into a

qapi: Fix C identifiers generated for names containing '.'
c_fun() maps '.' to '_', c_var() doesn't. Nothing prevents '.' in
QAPI names that get passed to c_var().
Which QAPI names get passed to c_fun(), to c_var(), or to both is not
obvious. Names of command parameters and struct type members get
passed to c_var().
c_var() strips a leading '*', but this cannot happen. c_fun()
doesn't.
Fix c_var() to work exactly like c_fun().
Perhaps they should be replaced by a single mapping function.

hw/intc/arm_gic: Make ICCICR/GICC_CTLR banked
ICCICR/GICC_CTLR is banked in GICv1 implementations with Security
Extensions or in GICv2 in independent from Security Extensions.
This makes it possible to enable forwarding of interrupts from
the CPU interfaces to the connected processors for Group0 and Group1.
We also allow to set additional bits like AckCtl and FIQEn by changing
the type from bool to uint32. Since the field does not only store the
enable bit anymore and since we are touching the vmstate, we use the
opportunity to rename the field to cpu_ctlr.

hw/intc/arm_gic: Add Interrupt Group Registers
The Interrupt Group Registers allow the guest to configure interrupts
into one of two groups, where Group0 are higher priority and may
be routed to IRQ or FIQ, and Group1 are lower priority and always
routed to IRQ. (In a GIC with the security extensions Group0 is
Secure interrupts and Group 1 is NonSecure.)
The GICv2 always supports interrupt grouping; the GICv1 does only
if it implements the security extensions.
This patch implements the ability to read and write the registers;
the actual functionality the bits control will be added in a
subsequent patch.

hw/sd: Don't pass BlockBackend to sd_reset()
The only valid BlockBackend to pass to sd_reset() is the one for
the SD card, which is sd->blk. Drop the second argument from this
function in favour of having it just use sd->blk.

armv7m_nvic: systick: Reload the RELOAD value and count down only if ENABLE bit is set
Consider the following pseudo code to configure SYSTICK (The
recommended programming sequence from "the definitive guide to the
arm cortex-m3"):
SYSTICK Reload Value Register = 0xffff
SYSTICK Current Value Register = 0
SYSTICK Control and Status Register = 0x7
The pseudo code "SYSTICK Current Value Register = 0" leads to invoking
systick_reload(). As a consequence, the systick.tick member is updated
and the systick timer starts to count down when the ENABLE bit of
SYSTICK Control and Status Register is cleared.
The worst case is that: during the system initialization, the reset
value of the SYSTICK Control and Status Register is 0x00000000.
When the code "SYSTICK Current Value Register = 0" is executed, the
systick.tick member is accumulated with "(s->systick.reload + 1) *
systick_scale(s)". The systick_scale() gets the external_ref_clock
scale because the CLKSOURCE bit of the SYSTICK Control and Status
Register is cleared. This is the incorrect behavior because of the
code "SYSTICK Control and Status Register = 0x7". Actually, we want
the processor clock instead of the external reference clock.
This incorrect behavior defers the generation of the first interrupt.
The patch fixes the above-mentioned issue by setting the systick.tick
member and modifying the systick timer only if the ENABLE bit of
the SYSTICK Control and Status Register is set.
In addition, the Cortex-M3 Devices Generic User Guide mentioned that
"When ENABLE is set to 1, the counter loads the RELOAD value from the
SYST RVR register and then counts down". This patch adheres to the
statement of the user guide.

rocker: add new rocker switch device
Rocker is a simulated ethernet switch device. The device supports up to 62
front-panel ports and supports L2 switching and L3 routing functions, as well
as L2/L3/L4 ACLs. The device presents a single PCI device for each switch,
with a memory-mapped register space for device driver access.
Rocker device is invoked with -device, for example a 4-port switch:
-device rocker,name=sw1,len-ports=4,ports[0]=dev0,ports[1]=dev1, \
ports[2]=dev2,ports[3]=dev3
Each port is a netdev and can be paired with using -netdev id=<port name>.

rocker: add support for flow modification
We had support for flow add/del. This adds support for flow mod. I needed
this for L3 support where an existing route is modified using NLM_F_REPLACE.
For example:
ip route add 12.0.0.0/30 nexthop via 11.0.0.1 dev swp1
ip route change 12.0.0.0/30 nexthop via 11.0.0.9 dev swp2
The first cmd adds the route. The second cmd changes the existing route by
changing its nexthop info.
In the device, a mod operation results in the matching flow enty being modified
with the new settings. This is atomic to the device.

The QMP is converted from a Python literal to JSON first,
to ensure that it is viable input to the actual QMP parser.
As a side-effect, this JSON output will helpfully show all
the necessary conversions that were performed on the input,
illustrating that "True" was transformed back into "true",

Add a special processing mode to craft transactions.
By entering "transaction(" the shell will enter a special
mode where each subsequent command will be saved as a transaction
instead of executed as an individual command.
The transaction can be submitted by entering ")" on a line by itself.
Examples:
Separate lines:
(QEMU) transaction(
TRANS> block-dirty-bitmap-add node=drive0 name=bitmap1
TRANS> block-dirty-bitmap-clear node=drive0 name=bitmap0
TRANS> )
With a transaction action included on the first line:
(QEMU) transaction( block-dirty-bitmap-add node=drive0 name=bitmap2
TRANS> block-dirty-bitmap-add node=drive0 name=bitmap3
TRANS> )
As a one-liner, with just one transaction action:
(QEMU) transaction( block-dirty-bitmap-add node=drive0 name=bitmap0 )
As a side-effect of this patch, blank lines are now parsed as no-ops,
regardless of which shell mode you are in.

scripts: qmp-shell: Expand support for QMP expressions
This includes support for [] expressions, single-quotes in
QMP expressions (which is not strictly a part of JSON), and
the ability to use "True", "False" and "None" literals instead
of JSON's equivalent true, false, and null literals.
qmp-shell currently allows you to describe values as
JSON expressions:
key={"key":{"key2":"val"}}
But it does not currently support arrays, which are needed
for serializing and deserializing transactions:
key=[{"type":"drive-backup","data":{...}}]
qmp-shell also only currently accepts doubly quoted strings
as-per JSON spec, but QMP allows single quotes.
Lastly, python allows you to utilize "True" or "False" as
boolean literals, but JSON expects "true" or "false". Expand
qmp-shell to allow the user to type either, converting to the
correct type.
As a consequence of the above, the key=val parsing is also improved
to give better error messages if a key=val token is not provided.
CAVEAT: The parser is still extremely rudimentary and does not
expect to find spaces in {} nor [] expressions. This patch does
not improve this functionality.

json-parser: Accept 'null' in QMP
We document that in QMP, the client may send any json-value
for the optional "id" key, and then return that same value
on reply (both success and failures, insofar as the failure
happened after parsing the id). [Note that the output may
not be identical to the input, as whitespace may change and
since we may reorder keys within a json-object, but that this
still constitutes the same json-value]. However, we were not
handling the JSON literal null, which counts as a json-value
per RFC 7159.
Also, down the road, given the QAPI schema of {'*foo':'str'} or
{'*foo':'ComplexType'}, we could decide to allow the QMP client
to pass { "foo":null } instead of the current representation of
{ } where omitting the key is the only way to get at the default
NULL value. Such a change might be useful for argument
introspection (if a type in older qemu lacks 'foo' altogether,
then an explicit "foo":null probe will force an easily
distinguished error message for whether the optional "foo" key
is even understood in newer qemu). And if we add default values
to optional arguments, allowing an explicit null would be
required for getting a NULL value associated with an optional
string that has a non-null default. But all that can come at a
later day.
The 'check-unit' testsuite is enhanced to test that parsing
produces the same object as explicitly requesting a reference
to the special qnull object. In addition, I tested with:
$ ./x86_64-softmmu/qemu-system-x86_64 -qmp stdio -nodefaults
{"QMP": {"version": {"qemu": {"micro": 91, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}}
{"execute":"qmp_capabilities","id":null}
{"return": {}, "id": null}
{"id":{"a":null,"b":[1,null]},"execute":"quit"}
{"return": {}, "id": {"a": null, "b": [1, null]}}

qobject: Add a special null QObject
I'm going to fix the JSON parser to recognize null. The obvious
representation of JSON null as (QObject *)NULL doesn't work, because
the parser already uses it as an error value. Perhaps we should
change it to free NULL for null, but that's more than I can do right
now. Create a special null QObject instead.
The existing QDict, QList, and QString all represent something that
is a pointer in C and could therefore be associated with NULL. But
right now, all three of these sub-types are always non-null once
created, so the new null sentinel object is intentionally unrelated
to them.

commit ca4414804114fd0095b317785bc0b51862e62ebb

qemu-nbd: only send a limited number of errno codes on the wire
Right now, NBD includes potentially platform-specific error values in
the wire protocol.
Luckily, most common error values are more or less universal: in
particular, of all errno values <= 34 (up to ERANGE), they are all the
same on supported platforms except for 11 (which is EAGAIN on Windows and
Linux, but EDEADLK on Darwin and the *BSDs). So, in order to guarantee
some portability, only keep a handful of possible error codes and squash
everything else to EINVAL.
This patch defines a limited set of errno values that are valid for the
NBD protocol, and specifies recommendations for what error to return
in specific corner cases. The set of errno values is roughly based on
the errors listed in the read(2) and write(2) man pages, with some
exceptions:
- ENOMEM is added for servers that implement copy-on-write or other
formats that require dynamic allocation.
- EDQUOT is not part of the universal set of errors; it can be changed
to ENOSPC on the wire format.
- EFBIG is part of the universal set of errors, but it is also changed
to ENOSPC because it is pretty similar to ENOSPC or EDQUOT.
Incoming values will in general match system errno values, but not
on the Hurd which has different errno values (they have a "subsystem
code" equal to 0x10 in bits 24-31). The Hurd is probably not something
to which QEMU has been ported, but still do the right thing and
reverse-map the NBD errno values to the system errno values.
The corresponding patch to the NBD protocol description can be found at
http://article.gmane.org/gmane.linux.drivers.nbd.general/3154.

rules.mak: Force CFLAGS for all objects in DSO
Because of the trick of process-archive-undefs, all .mo objects, even
with --enable-modules, are dependencies of executables.
This breaks CFLAGS propogation because the compiling of module object
will happen too early before building for DSO.
With GCC 5, the linking would fail because .o doesn't have -fPIC. Also,
BUILD_DSO will be missed. (module-common.o will have it, so the stamp
symbol was still liked in .so).
Fix the problem by forcing the CFLAGS on individual .o-cflags during
unnest-vars.

usb: fix usb-net segfault
The dev->config pointer isn't set until guest
system initializes usb devices (via
usb_desc_set_config). However qemu networking can
go through some motions prior to that, e.g.:
#0 is_rndis (s=0x555557261970) at hw/usb/dev-network.c:653
#1 0x000055555585f723 in usbnet_can_receive (nc=0x55555641e820) at hw/usb/dev-network.c:1315
#2 0x000055555587635e in qemu_can_send_packet (sender=0x5555572660a0) at net/net.c:470
#3 0x0000555555878e34 in net_hub_port_can_receive (nc=0x5555562d7800) at net/hub.c:101
#4 0x000055555587635e in qemu_can_send_packet (sender=0x5555562d7980) at net/net.c:470
#5 0x000055555587dbca in tap_can_send (opaque=0x5555562d7980) at net/tap.c:172
The command to reproduce most reliably was:
qemu-system-i386 -usb -device usb-net,vlan=0 -net tap,vlan=0
This wasn't strictly a problem with tap. Other
networking endpoints (vde, user) could trigger
this problem as well.

s390x/kvm: migrate vcpu interrupt state
This patch adds support to migrate vcpu interrupts.
We use ioctl KVM_S390_GET_IRQ_STATE and _SET_IRQ_STATE
to get/set the complete interrupt state for a vcpu.

s390x: move fpu regs into a subsection of the vmstate
Let's move the floating point registers into a seperate subsection and
bump up the version id. This cleans up the current vmstate and will
allow for a future extension with vector registers in a compatible way.
This patch is based on a patch from Eric Farman.

s390x/kvm: use ioctl KVM_S390_IRQ for vcpu interrupts
KVM_S390_INT uses only two parameter fields. This is not
enough to pass all required information for certain interrupts.
A new ioctl KVM_S390_IRQ is available which allows us to
inject all local interrupts as defined in the Principles of
Operation. It takes a struct kvm_s390_irq as a parameter
which can store interrupt payload data for all interrupts.
Let's use the new ioctl for injecting vcpu interrupts.

virtio-ccw: implement ->device_plugged
Let's move operations that are only valid after the backend has been
realized to a ->device_plugged callback, just as virtio-pci does.
Also reorder setting up the host feature bits to the sequence used

While we're at it, also add a ->device_unplugged callback to stop
ioeventfd, just to be on the safe side.

virtio-ccw: change realization sequence
virtio-ccw has an odd sequence of realizing devices: first the
device-specific relization (net, block, ...), then the generic
realization. It feels less odd to have the generic realization
callback trigger the device-specific realization instead (and this
also matches what virtio-pci does).
One thing to note: We need to defer initializing the cu model in the
sense id data until after the device-specific realization has been
performed, as we need to refer to the virtio device's device_id.

s390-virtio: use common features
We used to avoid enabling event_idx for virtio-blk devices via
s390-virtio, but we now have a workaround in place for guests trying
to use the device before setting DRIVER_OK. Therefore, let's add
DEFINE_VIRTIO_COMMON_FEATURES to the base device so all devices get
those common features - and make s390-virtio use the same mechanism
as the other transports do.

s390-virtio: Accommodate guests using virtqueues too early
Feature updates are not a synchronuous operation for the legacy
s390-virtio transport. This transport syncs the guest feature bits
(those from finalize) on the set_status hypercall. Before that qemu
thinks that features are zero, which means QEMU will misbehave, e.g.
it will not write the event index, even if the guest asks for it.
Let's detect the case where a kick happens before the driver is ready
and force sync the features.
With this workaround, it is now safe to switch to the common feature
bit handling code as used by all other transports.

qapi: Check for member name conflicts with a base class
Our type inheritance for both 'struct' and for flat 'union' merges
key/value pairs from the base class with those from the type in
question. Although the C code currently boxes things so that there
is a distinction between which member is referred to, the QMP wire
format does not allow passing a key more than once in a single
object. Besides, if we ever change the generated C code to not be
quite so boxy, we'd want to avoid duplicate member names there,
too.
Fix a testsuite entry added in an earlier patch, as well as adding
a couple more tests to ensure we have appropriate coverage. Ensure
that collisions are detected, regardless of whether there is a
difference in opinion on whether the member name is optional.

qapi: Support (subset of) \u escapes in strings
The handling of \ inside QAPI strings was less than ideal, and
really only worked JSON's \/, \\, \", and our extension of \'
(an obvious extension, when you realize we use '' instead of ""
for strings). For other things, like '\n', it resulted in a
literal 'n' instead of a newline.
Of course, at the moment, we really have no use for escaped
characters, as QAPI has to map to C identifiers, and we currently
support ASCII only for that. But down the road, we may add
support for default values for string parameters to a command
or struct; if that happens, it would be nice to correctly support
all JSON escape sequences, such as \n or \uXXXX. This gets us
closer, by supporting Unicode escapes in the ASCII range.
Since JSON does not require \OCTAL or \xXX escapes, and our QMP
implementation does not understand them either, I intentionally
reject it here, but it would be an easy addition if we desired it.
Likewise, intentionally refusing the NUL byte means we don't have
to worry about C strings being shorter than the qapi input.

qapi: Drop tests for inline nested structs
A future patch will be using a 'name':{dictionary} entry in the
QAPI schema to specify a default value for an optional argument;
but existing use of inline nested structs conflicts with that goal.
More precisely, a definition in the QAPI schema associates a name
with a set of properties:
Example 1: { 'struct': 'Foo', 'data': { MEMBERS... } }
associates the global name 'Foo' with properties (meta-type struct)
and MEMBERS...
Example 2: 'mumble': TYPE
within MEMBERS... above associates 'mumble' with properties (type
TYPE) and (optional false) within type Foo
The syntax of example 1 is extensible; if we need another property,
we add another name/value pair to the dictionary (such as
'base':TYPE). The syntax of example 2 is not extensible, because
the right hand side can only be a type.
We have used name encoding to add a property: "'*mumble': 'int'"
associates 'mumble' with (type int) and (optional true). Nice,
but doesn't scale. So the solution is to change our existing uses
to be syntactic sugar to an extensible form:
NAME: TYPE --> NAME: { 'type': TYPE, 'optional': false }
*ONAME: TYPE --> ONAME: { 'type': TYPE, 'optional': true }
This patch fixes the testsuite to avoid inline nested types, by
breaking the nesting into explicit types; it means that the type
is now boxed instead of unboxed in C code, but makes no difference
on the wire (and if desired, a later patch could change the
generator to not do so much boxing in C). When touching code to
add new allocations, also convert existing allocations to
consistently prefer typesafe g_new0 over g_malloc0 when a type
name is involved.

Referring to "type" as both a meta-type (built-in, enum, union,

is only made worse by the fact that the generator mostly already

Now that we have a way to validate every type, we can also be
stricter about enforcing that callers that want to bypass
type safety in generated code. Prior to this patch, it didn't
matter what value was associated with the key 'gen', but it
looked odd that 'gen':'yes' could result in bypassing the
generated code. These changes also enforce the changes made
earlier in the series for documentation and consolidation of
using '**' as the wildcard type, as well as 'gen':false as the
canonical spelling for requesting type bypass.
Note that 'gen':false is a one-way switch away from the default;
we do not support 'gen':true (similar for 'success-response').
In practice, this doesn't matter.

qapi: Whitelist commands that don't return dictionary
...or an array of dictionaries. Although we have to cater to
existing commands, returning a non-dictionary means the command
is not extensible (no new name/value pairs can be added if more
information must be returned in parallel). By making the
whitelist explicit, any new command that falls foul of this
practice will have to be self-documenting, which will encourage
developers to either justify the action or rework the design to
use a dictionary after all.
It's a little bit sloppy that we share a single whitelist among
three clients (it's too permissive for each). If this is a
problem, a future patch could tighten things by having the
generator take the whitelist as an argument (as in
scripts/qapi-commands.py --legacy-returns=...), or by having
the generator output C code that requires explicit use of the
whitelist (as in:
#ifndef FROBNICATE_LEGACY_RETURN_OK
# error Command 'frobnicate' should return a dictionary
#endif
then having the callers define appropriate macros). But until
we need such fine-grained separation (if ever), this patch does
the job just fine.

qapi: Require valid names
Previous commits demonstrated that the generator overlooked various
bad naming situations:
- types, commands, and events need a valid name
- enum members must be valid names, when combined with prefix
- union and alternate branches cannot be marked optional
Valid upstream names match [a-zA-Z][a-zA-Z0-9_-]*; valid downstream
names match __[a-zA-Z][a-zA-Z0-9._-]*. Enumerations match the
weaker [a-zA-Z0-9._-]+ (in part thanks to QKeyCode picking an enum
that starts with a digit, which we can't change now due to
backwards compatibility). Rather than call out three separate
regex, this patch just uses a broader combination that allows both
upstream and downstream names, as well as a small hack that
realizes that any enum name is merely a suffix to an already valid
name prefix (that is, any enum name is valid if prepending _ fits
the normal rules).
We could reject new enumeration names beginning with a digit by
whitelisting existing exceptions. We could also be stricter
about the distinction between upstream names (no leading
underscore, no use of dot) and downstream (mandatory leading
double underscore), but it is probably not worth the bother.

returns-whitelist is a case where we have historically allowed
returning something other than a JSON object from particular

but it would be nicer to avoid adding such commands in the future,
because any return that is not an (array of) object cannot be
easily extended if future qemu wants to return additional

qapi: Unify type bypass and add tests
For a few QMP commands, we are forced to pass an arbitrary type
without tracking it properly in QAPI. Among the existing clients,
this unnamed type was spelled 'dict', 'visitor', and '**'; this
patch standardizes on '**', matching the documentation changes
earlier in the series.
Meanwhile, for the 'gen' key, we have been ignoring the value,
although the schema consistently used "'no'" ('success-response'
was hard-coded to checking for 'no'). But now that we can support
a literal "false" in the schema, we might as well use that rather
than ignoring the value or special-casing a random string. Note
that these are one-way switches (use of 'gen':true is not the same
as omitting 'gen'). Also, the use of '**' requires 'gen':false,
but the use of 'gen':false does not mandate the use of '**'.
There is no difference to the generated code. Add some tests on
what we'd like to guarantee, although it will take later patches
to clean up test results and actually enforce the use of a bool
parameter.

qapi: Better error messages for duplicated expressions

- redeclaration of a type name, whether by the same or different
metatype
- redeclaration of a command or event
- collision of a type with implicit 'Kind' enum for a union
- collision with an implicit MAX enum constant
Since the c_type() function in the generator treats all names
as being in the same namespace, this patch adds a global array
to track all known names and their source, to prevent collisions
before it can cause further problems. While valid .json files

qapi: Better error messages for bad expressions
The previous commit demonstrated that the generator overlooked some
fairly basic broken expressions:
- missing metataype
- metatype key has a non-string value
- unknown key in relation to the metatype
- conflicting metatype (this patch treats the second metatype as an
unknown key of the first key visited, which is not necessarily the
first key the user typed)
Add check_keys to cover these situations, and update testcases to
match. A couple other tests (enum-missing-data, indented-expr) had
to change since the validation added here occurs so early.
Conversely, changes to ident-with-escape results show that we still
have problems where our handling of escape sequences differs from
true JSON, which will matter down the road if we allow arbitrary
default string values for optional parameters (but for now is not
too bad, as we currently can avoid unicode escaping as we don't
need to represent anything beyond C identifier material).
While valid .json files won't trigger any of these cases, we might
as well be nicer to developers that make a typo while trying to add

qapi: Segregate anonymous unions into alternates in generator
Special-casing 'discriminator == {}' for handling anonymous unions
is getting awkward; since this particular type is not always a
dictionary on the wire, it is easier to treat it as a completely
different class of type, "alternate", so that if a type is listed
in the union_types array, we know it is not an anonymous union.
This patch just further segregates union handling, to make sure that
anonymous unions are not stored in union_types, and splitting up
check_union() into separate functions. A future patch will change
the qapi grammar, and having the segregation already in place will
make it easier to deal with the distinct meta-type.

qapi: Prepare for catching more semantic parse errors
This patch widens the scope of a try block (with the attending
reindentation required by Python) in preparation for a future
patch adding more instances of QAPIExprError inside the block.
It's easier to separate indentation from semantic changes, so
this patch has no real behavior change.

qapi: Tighten checking of unions
Previous commits demonstrated that the generator had several
flaws with less-than-perfect unions:
- a simple union that listed the same branch twice (or two variant
names that map to the same C enumerator, including the implicit
MAX sentinel) ended up generating invalid C code
- an anonymous union that listed two branches with the same qtype
ended up generating invalid C code
- the generator crashed on anonymous union attempts to use an
array type
- the generator was silently ignoring a base type for anonymous
unions
- the generator allowed unknown types or nested anonymous unions
as a branch in an anonymous union

qapi: Forbid base without discriminator in unions
None of the existing QMP or QGA interfaces uses a union with a
base type but no discriminator; it is easier to avoid this in the
generator to save room for other future extensions more likely to
be useful. An earlier commit added a union-base-no-discriminator
test to ensure that we eventually give a decent error message;
likewise, removing UserDefUnion outright is okay, because we moved
all the tests we wish to keep into the tests of the simple union
UserDefNativeListUnion in the previous commit. Now is the time to
actually forbid simple union with base, and remove the last
vestiges from the testsuite.

qapi: Clean up test coverage of simple unions
The tests of UserDefNativeListUnion serve to validate code
generation of simple unions without a base type, except that it
did not have full coverage in the strict test. The next commits
will remove tests and support for simple unions with a base type,
so there is no real loss at repurposing that test here as
opposed to churn of adding a new test then deleting the old one.
Fix some indentation and long lines while at it.

qapi: Add some union tests
Demonstrate that the qapi generator doesn't deal well with unions
that aren't up to par. Later patches will update the expected
reseults as the generator is made stricter. A few tests work
as planned, but most show poor or missing error messages.
Of particular note, qapi-code-gen.txt documents 'base' only for
flat unions, but the tests here demonstrate that we currently allow
a 'base' to a simple union, although it is exercised only in the
testsuite. Later patches will remove this undocumented feature, to
give us more flexibility in adding other future extensions to union
types. For example, one possible extension is the idea of a
type-safe simple enum, where added fields tie the discriminator to
a user-defined enum type rather than creating an implicit enum from
the names in 'data'. But adding such safety on top of a simple
enum with a base type could look ambiguous with a flat enum;
besides, the documentation also mentions how any simple union can
be represented by an equivalent flat union. So it will be simpler
to just outlaw support for something we aren't using.

qapi: Better error messages for bad enums
The previous commit demonstrated that the generator had several
flaws with less-than-perfect enums:
- an enum that listed the same string twice (or two variant
strings that map to the same C enumerator) ended up generating
an invalid C enum
- because the generator adds a _MAX terminator to each enum,
the use of an enum member 'max' can also cause this clash
- if an enum omits 'data', the generator left a python stack
trace rather than a graceful message
- an enum that used a non-array 'data' was silently accepted by
the parser
- an enum that used non-string members in the 'data' member
was silently accepted by the parser
Add check_enum to cover these situations, and update testcases
to match. While valid .json files won't trigger any of these
cases, we might as well be nicer to developers that make a typo
while trying to add new QAPI code.

that we don't care about Unicode strings, and to just always
use the simpler isinstance(foo, str) everywhere.

qapi: Add copyright declaration on docs
While our top-level COPYING with its GPLv2+ license applies to
any documentation file that omits explicit instructions, these
days it's better to be a good example of calling out our
intentions. Correct use of GPL requires the use of a copyright
statement, so I'm adding notice to two QAPI documents, by
attributing these files to the initial authors and major
contributors. I used:
$ git blame --line-porcelain $file \
| sed -n 's/^author //p' | sort | uniq -c | sort -rn
to determine authorship of these two files. qmp-spec.txt blames
entirely to Red Hat (easy, since my contribution falls in that
category); while qapi-code-gen.txt has multiple contributors
representing multiple entities. But since it was originally
supplied by Michael Roth, the notice I added there copies the
notice he has used in other files. As there is no intended
change in license from the implicit one previously present from
the top level, I have not bothered to CC other contributors;
if we want to weaken things to something looser (such as LGPL)
so that there is no question that someone re-implementing the
spec is not forced to use GPL, that would be a different commit.

Note that using an entire byte for some enums that need less than
that wastes a few bits (noticeable in 32 bits, where we use
20 bytes instead of 16) but avoids extraction code, which overall
is a win--I've tested several variations of the patch, and the appended
is the best performer for OpenSSL's bntest by a very small margin:

kvm: Silence warning from valgrind
valgrind complains here about uninitialized bytes with the following message:
==17814== Syscall param ioctl(generic) points to uninitialised byte(s)
==17814== at 0x466A780: ioctl (in /usr/lib64/power8/libc-2.17.so)
==17814== by 0x100735B7: kvm_vm_ioctl (kvm-all.c:1920)
==17814== by 0x10074583: kvm_set_ioeventfd_mmio (kvm-all.c:574)
Let's fix it by using a proper struct initializer in kvm_set_ioeventfd_mmio().

Enable NVMe start controller for Windows guest.
Windows seems to send two separate calls to NVMe controller configuration. The
first sends configuration info and the second the enable bit. I couldn't
enable the Windows 8.1 in-box NVMe driver with base Qemu. I made the
following change to store the configuration data and then handle enable and
NVMe driver works on Windows 8.1.
I am not a Windows expert and I'm not entirely sure this is the correct
approach. I'm offering it for anyone who wishes to use NVMe on Windows 8.1
using Qemu.
I have tested this change with Linux and Windows guests with NVMe devices.

kvm: better advice for failed s390x startup
If KVM_CREATE failed on s390x, we print a hint to enable the switch_amode
kernel parameter. This only applies to old kernels, and only if the
error was -EINVAL. Moreover, with new kernels, the most likely reason
for -EINVAL is that pgstes were not enabled.
Let's update the error message to give a better hint on where things
may need fixing.

s390x/kvm: Support access register mode for KVM_S390_MEM_OP ioctl
Access register mode is one of the modes that control dynamic address
translation. In this mode the address space is specified by values of
the access registers. The effective address-space-control element is
obtained from the result of the access register translation. See
the "Access-Register Introduction" section of the chapter 5 "Program
Execution" in "Principles of Operations" for more details.
When the CPU is in AR mode, the s390_cpu_virt_mem_rw() function must
know which access register number to use for address translation.
This patch does several things:
- add new parameter 'uint8_t ar' to that function
- decode ar number from intercepted instructions
- pass the ar number to s390_cpu_virt_mem_rw(), which in turn passes it
to the KVM_S390_MEM_OP ioctl.

s390x/kvm: Put vm name, extended name and UUID into STSI322 SYSIB
KVM prefills the SYSIB, returned by STSI 3.2.2. This patch allows
userspace to intercept execution, and fill in the values, that are
known to qemu: machine name (8 chars), extended machine name (256
chars), extended machine name encoding (equals 2 for UTF-8) and UUID.
STSI322 qemu handler also finds a highest virtualization level in
level-3 virtualization stack that doesn't support Extended Names
(Ext Name delimiter) and propagates zero Ext Name to all levels below,
because this level is not capable of managing Extended Names of lower
levels.

nbd/trivial: fix type cast for ioctl
This fixes ioctl behavior on powerpc e6500 platforms with 64bit kernel and 32bit
userspace. The current type cast has no effect there and the value passed to the
kernel is still 0. Probably an issue related to the compiler, since I'm assuming
the same configuration works on a similar setup on x86.
Also ensure consistency with previous type cast in TRACE message.

Makefile.target: prepend $libs_softmmu to $LIBS
I discovered a problem when trying to build QEMU statically with gcc.
libm is an element of LIBS while libpixman-1 is an element in
libs_softmmu. Libpixman references functions in libm, so the original
ordering makes linking fail.
This fix is to reorder $libs_softmmu and $LIBS to make -lm appear after
-lpixman-1. However I'm not quite sure if this is the right fix, hence
the RFC tag.
Normally QEMU is built with c++ compiler which happens to link in libm
(at least this is the case with g++), so building QEMU statically
normally just works and nobody notices this issue.

configure: Add support for tcmalloc
This adds "--enable-tcmalloc" and "--disable-tcmalloc" to allow linking
to libtcmalloc from gperftools.
tcmalloc is a malloc implementation that works well with threads and is
fast, so it is good for performance.
It is disabled by default, because the MALLOC_PERTURB_ flag we use in
tests doesn't work with tcmalloc. However we can enable tcmalloc
specific heap checker and profilers later.
An IOPS gain can be observed with virtio-blk-dataplane, other parts of
QEMU will directly benefit from it as well:

vfio-pci: Reset workaround for AMD Bonaire and Hawaii GPUs
Somehow these GPUs manage not to respond to a PCI bus reset, removing
our primary mechanism for resetting graphics cards. The result is
that these devices typically work well for a single VM boot. If the
VM is rebooted or restarted, the guest driver is not able to init the
card from the dirty state, resulting in a blue screen for Windows
guests.
The workaround is to use a device specific reset. This is not 100%
reliable though since it depends on the incoming state of the device,
but it substantially improves the usability of these devices in a VM.

vfio-pci: Fix error path sign
This is an impossible error path due to the fact that we're reading a
kernel provided, rather than user provided link, which will certainly
always fit in PATH_MAX. Currently it returns a fixed 26 char path
plus %d group number, which typically maxes out at double digits.
However, the caller of the initfn certainly expects a less-than zero
return value on error, not just a non-zero value. Therefore we
should correct the sign here.

vfio-pci: Further fix BAR size overflow
In an analysis by Laszlo, the resulting type of our calculation for
the end of the MSI-X table, and thus the start of memory after the
table, is uint32_t. We're therefore not correctly preventing the
corner case overflow that we intended to fix here where a BAR >=4G
could place the MSI-X table to end exactly at the 4G boundary. The
MSI-X table offset is defined by the hardware spec to 32bits, so we
simply use a cast rather than changing data structure types. This
scenario is purely theoretically, typically the MSI-X table is located
at the front of the BAR.

virtio-scsi: Move DEFINE_VIRTIO_SCSI_FEATURES to virtio-scsi
So far virtio-scsi-device can't expose host features to guest while
using virtio-mmio because it doesn't set DEFINE_VIRTIO_SCSI_FEATURES on
backend or transport.
The host features belong to the backends while virtio-scsi-pci,
virtio-scsi-s390 and virtio-scsi-ccw set the DEFINE_VIRTIO_SCSI_FEATURES
on transports. But they already have the ability to forward property
accesses to the backend child. So if we move the host features to
backends, it doesn't break the backwards compatibility for them and
make host features work while using virtio-mmio.

transports just sync the host features from backends.

pci: Merge pci_nic_init() into pci_nic_init_nofail()
The error reporting in pci_nic_init() is quite erratic: Some errors
are printed directly with error_report(), and some are passed back
to the caller pci_nic_init_nofail() via an Error pointer.
Since pci_nic_init() is only used by pci_nic_init_nofail(), the
functions can be simply merged to clean up this inconsistency.

iotests: add QMP event waiting queue
A filter is added to allow callers to request very specific
events to be pulled from the event queue, while leaving undesired
events still in the stream.
This allows us to poll for completion data for multiple asynchronous
events in any arbitrary order.
A new timeout context is added to the qmp pull_event method's
wait parameter to allow tests to fail if they do not complete
within some expected period of time.
Also fixed is a bug in qmp.pull_event where we try to retrieve an event
from an empty list if we attempt to retrieve an event with wait=False
but no events have occurred.

- Less than the granularity, but across a boundary
- Less than sizeof(unsigned long)
- Less than sizeof(unsigned long), but across a ulong boundary

qmp: Add support of "dirty-bitmap" sync mode for drive-backup
For "dirty-bitmap" sync mode, the block job will iterate through the
given dirty bitmap to decide if a sector needs backup (backup all the
dirty clusters and skip clean ones), just as allocation conditions of
"top" sync mode.

block: Add bitmap successors
A bitmap successor is an anonymous BdrvDirtyBitmap that is intended to
be created just prior to a sensitive operation (e.g. Incremental Backup)
that can either succeed or fail, but during the course of which we still
want a bitmap tracking writes.
On creating a successor, we "freeze" the parent bitmap which prevents
its deletion, enabling, anonymization, or creating a bitmap with the
same name.
On success, the parent bitmap can "abdicate" responsibility to the
successor, which will inherit its name. The successor will have been
tracking writes during the course of the backup operation. The parent
will be safely deleted.
On failure, we can "reclaim" the successor from the parent, unifying
them such that the resulting bitmap describes all writes occurring since
the last successful backup, for instance. Reclamation will thaw the
parent, but not explicitly re-enable it.
BdrvDirtyBitmap operations that target a single bitmap are protected
by assertions that the bitmap is not frozen and/or disabled.
BdrvDirtyBitmap operations that target a group of bitmaps, such as
bdrv_{set,reset}_dirty will ignore frozen/disabled drives with a
conditional instead.
Internal functions that enable/disable dirty bitmaps have assertions
added to them to prevent modifying frozen bitmaps.

block: Add bitmap disabled status
Add a status indicating the enabled/disabled state of the bitmap.
A bitmap is by default enabled, but you can lock the bitmap into
a read-only state by setting disabled = true.
A previous version of this patch added a QMP interface for changing
the state of the bitmap, but it has since been removed for now until
a use case emerges where this state must be revealed to the user.
The disabled state WILL be used internally for bitmap migration and
bitmap persistence.

hbitmap: add hbitmap_merge
We add a bitmap merge operation to assist in error cases
where we wish to combine two bitmaps together.
This is algorithmically O(bits) provided HBITMAP_LEVELS remains
constant. For a full bitmap on a 64bit machine:
sum(bits/64^k, k, 0, HBITMAP_LEVELS) ~= 1.01587 * bits
We may be able to improve running speed for particularly sparse
bitmaps by using iterators, but the running time for dense maps
will be worse.
We present the simpler solution first, and we can refine it later
if needed.

qmp: Add block-dirty-bitmap-add and block-dirty-bitmap-remove
The new command pair is added to manage a user created dirty bitmap. The
dirty bitmap's name is mandatory and must be unique for the same device,
but different devices can have bitmaps with the same names.
The granularity is an optional field. If it is not specified, we will
choose a default granularity based on the cluster size if available,
clamped to between 4K and 64K to mirror how the 'mirror' code was
already choosing granularity. If we do not have cluster size info
available, we choose 64K. This code has been factored out into a helper
shared with block/mirror.
This patch also introduces the 'block_dirty_bitmap_lookup' helper,
which takes a device name and a dirty bitmap name and validates the
lookup, returning NULL and setting errp if there is a problem with
either field. This helper will be re-used in future patches in this
series.
The types added to block-core.json will be re-used in future patches
in this series, see:
'qapi: Add transaction support to block-dirty-bitmap-{add, enable, disable}'

qmp: fill in the image field in BlockDeviceInfo
The image field in BlockDeviceInfo is supposed to contain an ImageInfo
object. However that is being filled in by bdrv_query_info(), not by
bdrv_block_device_info(), which is where BlockDeviceInfo is actually
created.
Anyone calling bdrv_block_device_info() directly will get a null image
field. As a consequence of this, the HMP command 'info block -n -v'
crashes QEMU.
This patch moves the code that fills in that field from
bdrv_query_info() to bdrv_block_device_info().

block: avoid unnecessary bottom halves
bdrv_aio_* APIs can use coroutines to achieve asynchronicity. However,
the coroutine may terminate without having yielded back to the caller
(for example because of something that invokes a nested event loop,
or because the coroutine is doing nothing at all). In this case,
the bdrv_aio_* API must delay the completion to the next iteration
of the main loop, because bdrv_aio_* will never invoke the callback
before returning.
This can be done with a bottom half, and indeed bdrv_aio_* is always
using one for simplicity. It is possible to gain some performance
(~3%) by avoiding this in the common case. A new field in the
BlockAIOCBCoroutine struct is set to true until the first time the
corotine has yielded to its creator, and completion goes through a
new function bdrv_co_complete. If the flag is false, bdrv_co_complete
invokes the callback immediately. If it is true, the caller will
notice that the coroutine has completed and schedule the bottom
half itself.

blockjob: Allow nested pause
This patch changes block_job_pause to increase the pause counter and
block_job_resume to decrease it.
The counter will allow calling block_job_pause/block_job_resume
unconditionally on a job when we need to suspend the IO temporarily.
From now on, each block_job_resume must be paired with a block_job_pause
to keep the counter balanced.
The user pause from QMP or HMP will only trigger block_job_pause once
until it's resumed, this is achieved by adding a user_paused flag in
BlockJob.
One occurrence of block_job_resume in mirror_complete is replaced with
block_job_enter which does what is necessary.
In block_job_cancel, the cancel flag is good enough to instruct
coroutines to quit loop, so use block_job_enter to replace the unpaired
block_job_resume.
Upon block job IO error, user is notified about the entering to the
pause state, so this pause belongs to user pause, set the flag
accordingly and expect a matching QMP resume.

qemu-img convert: Rewrite copying logic
The implementation of qemu-img convert is (a) messy, (b) buggy, and
(c) less efficient than possible. The changes required to beat some
sense into it are massive enough that incremental changes would only
make my and the reviewers' life harder. So throw it away and reimplement
it from scratch.
Let me give some examples what I mean by messy, buggy and inefficient:
(a) The copying logic of qemu-img convert has two separate branches for
compressed and normal target images, which roughly do the same -
except for a little code that handles actual differences between
compressed and uncompressed images, and much more code that
implements just a different set of optimisations and bugs. This is
unnecessary code duplication, and makes the code for compressed
output (unsurprisingly) suffer from bitrot.
The code for uncompressed ouput is run twice to count the the total
length for the progress bar. In the first run it just takes a
shortcut and runs only half the loop, and when it's done, it toggles
a boolean, jumps out of the loop with a backwards goto and starts
over. Works, but pretty is something different.
(b) Converting while keeping a backing file (-B option) is broken in
several ways. This includes not writing to the image file if the
input has zero clusters or data filled with zeros (ignoring that the
backing file will be visible instead).
It also doesn't correctly limit every iteration of the copy loop to
sectors of the same status so that too many sectors may be copied to
in the target image. For -B this gives an unexpected result, for
other images it just does more work than necessary.
Conversion with a compressed target completely ignores any target
backing file.
(c) qemu-img convert skips reading and writing an area if it knows from
metadata that copying isn't needed (except for the bug mentioned
above that ignores a status change in some cases). It does, however,
read from the source even if it knows that it will read zeros, and
then search for non-zero bytes in the read buffer, if it's possible
that a write might be needed.
This reimplementation of the copying core reorganises the code to remove
the duplication and have a much more obvious code flow, by essentially
splitting the copy iteration loop into three parts:
1. Find the number of contiguous sectors of the same status at the
current offset (This can also be called in a separate loop before the
copying loop in order to determine the total sectors for the progress
bar.)
2. Read sectors. If the status implies that there is no data there to
read (zero or unallocated cluster), don't do anything.
3. Write sectors depending on the status. If it's data, write it. If
we want the backing file to be visible (with -B), don't write it. If
it's zeroed, skip it if you can, otherwise use bdrv_write_zeroes() to
optimise the write at least where possible.

block: Switch to host monotonic clock for IO throttling
Currently, throttle timers won't make any progress when VCPU is not
running, which would stall the request queue in utils, qtest, vm
suspending, and live migration, without special handling.
Block jobs are confusingly inconsistent between with and without
throttling: if user sets a bps limit, stops the vm, then start a block
job, the block job will not make any progress; in contrary, if user
unsets the bps limit, or if it's not set, the block job will run
normally.
After this patch, with the host clock, even if the VCPUs are stopped,
the throttle queues will be processed.
This patch also enables potential to add throttle to bdrv_drain_all.
Currently all requests are drained immediately. In other words whenever
it is called, IO throttling goes ineffective (examples: system reset,
migration and many block job operations.). This is a loophole that guest
could exploit. If we use the host clock, we can later just trust the
nested poll. This could be done on top.
Note that for qemu-iotests case 093, which uses qtest, we still keep vm
clock so the script can control the clock stepping in order to be
deterministic.

hw/arm/nseries: convert ffs(3) to ctz32()
It is not clear from the code how a 0 parameter should be handled by the
hardware. Keep the same behavior as ffs(0) - 1 == -1.

bt-sdp: fix broken uuids power-of-2 calculation
The binary search in sdp_uuid_match() only works when the number of
elements to search is a power of two.
lo = record->uuid;
hi = record->uuids;
while (hi >>= 1)
if (lo[hi] <= val)
lo += hi;
return *lo == val;
I noticed that the record->uuids calculation in
sdp_service_record_build() was suspect:
record->uuids = 1 << ffs(record->uuids - 1);
Unlike most ffs(val) - 1 users, the expression is ffs(val - 1)!
Actually ffs() is the wrong function to use for power-of-2. Use
pow2ceil() to achieve the correct effect. Now the record->uuid[] array
is sized correctly and the binary search in sdp_uuid_match() should
work.
I'm not sure how to run/test this code.

savevm: create snapshot failed when id_str already exists
The command "virsh create" will fail in such condition: vm has two
disks: vda and vdb. vda has snapshot s1 with id "1", vdb doesn't have
s1 but has snapshot s2 with id "1". When we want to run command "virsh
create s1", del_existing_snapshots() only deletes s1 in vda, and
bdrv_snapshot_create() tries to create vdb's snapshot s1 with id "1",
but id "1" alreay exists in vdb with name "s2"!
The simplest way is call find_new_snapshot_id() unconditionally.

pci: remove hard-coded bar size in msix_init_exclusive_bar()
This patch lets msix_init_exclusive_bar() can calculate the bar and
pba size based on the number of MSI-X vectors other than using a
hard-coded limit 4096. This is needed to allow device to have more
than 128 MSI_X vectors. To keep migration compatibility, keep using
4096 as bar size and 2048 for pba offset.
Notes: We don't care about the case that using vectors > 128 for
legacy machine type. Since we limit the queue max to 64, so vectors >=
65 is meaningless.
Virtio device will be the first user for this.

virtio-pci: speedup MSI-X masking and unmasking
This patch tries to speed up the MSI-X masking and unmasking through
the mapping between vector and queues. With this patch it will there's
no need to go through all possible virtqueues, which may help to
reduce the time spent when doing MSI-X masking/unmasking a single
vector when more than hundreds or even thousands of virtqueues were
supported.
Tested with 80 queue pairs virito-net-pci by changing the smp affinity
in the background and doing netperf in the same time:
Before the patch:
5711.70 Gbits/sec
After the patch:
6830.98 Gbits/sec
About 19.6% improvements in throughput.

virtio: introduce vector to virtqueues mapping
Currently we will try to traverse all virtqueues to find a subset that
using a specific vector. This is sub optimal when we will support
hundreds or even thousands of virtqueues. So this patch introduces a
method which could be used by transport to get all virtqueues that
using a same vector. This is done through QLISTs and the number of
QLISTs was queried through a transport specific method. When guest
setting vectors, the virtqueue will be linked and helpers for traverse
the list was also introduced.
The first user will be virtio pci which will use this to speed up
MSI-X masking and unmasking handling.

target-i386: Remove AMD feature flag aliases from CPU model table
When CPU vendor is AMD, the AMD feature alias bits on
CPUID[0x80000001].EDX are already automatically copied from CPUID[1].EDX
on x86_cpu_realizefn(). When CPU vendor is Intel, those bits are
reserved and should be zero. On either case, those bits shouldn't be set
in the CPU model table.

address_space_translate_internal will clamp the *plen length argument
based on the size of the memory region being queried. The iommu walker
logic in addresss_space_translate was ignoring this by discarding the

length argument throughout the fn, removing the len local variable.

ioport: reserve the whole range of an I/O port in the AddressSpace
When an I/O port is more than 1 byte long, ioport.c is currently
creating "short" regions, for example 0x1ce-0x1ce for the 16-bit
Bochs index port. When I/O ports are memory mapped, and thus
accessed via a subpage_ops memory region, subpage_accepts gets
confused because it finds a hole at 0x1cf and rejects the access.
In order to fix this, modify registration of the region to cover
the whole size of the I/O port. Attempts to access an invalid
port will be blocked by find_portio returning NULL.
This only affects the VBE DISPI regions. For all other cases,
the MemoryRegionPortio entries for 2- or 4-byte accesses overlap
an entry for 1-byte accesses, thus the size of the memory region
is not affected.

ioport: loosen assertions on emulation of 16-bit ports
Right now, ioport.c assumes that the entire range specified with
MemoryRegionPortio includes a region with size == 1. This however
is not true for the VBE DISPI ports, which are 16-bit only. The
next patch will make these regions' length equal to two, which can
cause the assertions to trigger. Replace them with simple conditionals.
Also, ioport.c will emulate a 16-bit ioport with two distinct reads
or writes, even if one of the two accesses is out of the bounds given
by the MemoryRegionPortio array. Do not do this anymore, instead
discard writes to the incorrect register and read it as all-ones.
This ensures that the mrp->read and mrp->write callbacks get an
in-range ioport number.

monitor: Make client_migrate_info synchronous
Live migration with spice works like this today:
(1) client_migrate_info monitor cmd
(2) spice server notifies client, client connects to target host.
(3) qemu waits until spice client connect is finished.
(4) send over vmstate (i.e. main part of live migration).
(5) spice handover to target host.
(3) is implemented by making client_migrate_info a async monitor
command. This is the only async monitor command we have.
The original reason to implement this dance was that qemu did not accept
new tcp connections while the incoming migration was running, so (2) and
(4) could not be done in parallel. That issue was fixed long ago though.
Qemu version 1.3.0 (released Dec 2012) and newer happily accept tcp
connects while the incoming migration runs.
Time to drop step (3). This patch does exactly that, by making the
monitor command synchronous and removing the code needed to handle the
async monitor command in ui/spice-core.c

Now that we have memory access attribute information in the watchpoint
checking code, we can correctly implement handling of watchpoints
which should match only on userspace accesses, where LDRT/STRT/LDT/STT
from EL1 are treated as userspace accesses.

memory: Define API for MemoryRegionOps to take attrs and return status
Define an API so that devices can register MemoryRegionOps whose read
and write callback functions are passed an arbitrary pointer to some
transaction attributes and can return a success-or-failure status code.
This will allow us to model devices which:
* behave differently for ARM Secure/NonSecure memory accesses
* behave differently for privileged/unprivileged accesses
* may return a transaction failure (causing a guest exception)
for erroneous accesses
This patch defines the new API and plumbs the attributes parameter through
to the memory.c public level functions io_mem_read() and io_mem_write(),
where it is currently dummied out.
The success/failure response indication is also propagated out to
io_mem_read() and io_mem_write(), which retain the old-style
boolean true-for-error return.

qmp-commands: fix incorrect uses of ":O" specifier
As far as the QMP parser is concerned, neither the 'O' nor the 'q' format specifiers
put any constraint on the command. However, there are two differences:
1) from a documentation point of view 'O' says that this command takes
a dictionary. The dictionary will be converted to QemuOpts in the
handler to match the corresponding HMP command.
2) 'O' sets QMP_ACCEPT_UNKNOWNS, resulting in the command accepting invalid
extra arguments. For example the following is accepted:
{ "execute": "send-key",
"arguments": { "keys": [ { "type": "qcode", "data": "ctrl" },
{ "type": "qcode", "data": "alt" },
{ "type": "qcode", "data": "delete" } ], "foo": "bar" } }
Neither send-key nor migrate-set-capabilities take a QemuOpts-like
dictionary; they take an array of dictionaries. And neither command
really wants to have extra unknown arguments. Thus, the right
specifier to use in this case is 'q'; with this patch the above
command fails with
{"error": {"class": "GenericError", "desc": "Invalid parameter 'foo'"}}
as intended.

The image field in BlockDeviceInfo should never be null, however

This makes the 'info block -n -v' command crash QEMU.
The proper solution is probably to move the relevant code from

crash.

target-ppc: don't invalidate msr MSR_HVB bit in cpu_post_load
The invalidation code introduced in commit 2360b works by inverting most bits
of env->msr to ensure that hreg_store_msr() will forcibly update the CPU env
state to reflect the new msr value post-migration. Unfortunately
hreg_store_msr() is called with alter_hv set to 0 which preserves the MSR_HVB
state from the CPU env which is now the opposite value to what it should be.
Ensure that we don't invalidate the msr MSR_HVB bit during cpu_post_load so
that the correct value is restored. This fixes suspend/resume for PPC64.

Revert seccomp tests that allow it to be used on non-x86 architectures
Unfortunately it turns out that libseccomp 2.2 still does not work
correctly on non-x86 architectures; return to the previous configure
setup of insisting on libseccomp 2.1 or better and i386/x86_64 and
disabling seccomp support in all other situations.
This reverts the two commits:
* "seccomp: libseccomp version varying according to arch"
(commit 896848f0d3e2393905845ef2b244bb2601f9df0c)
* "seccomp: update libseccomp version and remove arch restriction"

pci: Fix crash with illegal "-net nic, model=xxx" option
Current QEMU crashes when specifying an illegal model with the

qemu-system-x86_64: Unsupported NIC model: n/a
Program received signal SIGSEGV, Segmentation fault.

The problem is that pci_nic_init_nofail() does not check whether the err
parameter from pci_nic_init has been set up and thus passes a NULL pointer
to error_report_err(). Fix it by correctly checking the err parameter.

tcg/tcg-op.c: Fix ld/st of 64 bit values on 32-bit bigendian hosts
Commit 951c6300f7 out-of-lined the 32-bit-host versions of
tcg_gen_{ld,st}_i64, but in the process it inadvertently changed
an #ifdef HOST_WORDS_BIGENDIAN to #ifdef TCG_TARGET_WORDS_BIGENDIAN.
Since the latter doesn't get defined anywhere this meant we always
took the "LE host" codepath, and stored the two halves of the value
in the wrong order on BE hosts. This typically breaks any 64-bit
guest on a 32-bit BE host completely, and will have possibly more
subtle effects even for 32-bit guests.
Switch the ifdef back to HOST_WORDS_BIGENDIAN.

newer libiscsi versions may return zero events from iscsi_which_events.
In this case iscsi_service will return immediately without any progress.
To avoid busy waiting for iscsi_which_events to change we deregister all
read and write handlers in this case and schedule a timer to periodically
check iscsi_which_events for changed events.
Next libiscsi version will introduce async reconnects and zero events
are returned while libiscsi is waiting for a reconnect retry.

aio: strengthen memory barriers for bottom half scheduling
There are two problems with memory barriers in async.c. The fix is
to use atomic_xchg in order to achieve sequential consistency between
the scheduling of a bottom half and the corresponding execution.
First, if bh->scheduled is already 1 in qemu_bh_schedule, QEMU does
not execute a memory barrier to order any writes needed by the callback
before the read of bh->scheduled. If the other side sees req->state as
THREAD_ACTIVE, the callback is not invoked and you get deadlock.
Second, the memory barrier in aio_bh_poll is too weak. Without this
patch, it is possible that bh->scheduled = 0 is not "published" until
after the callback has returned. Another thread wants to schedule the
bottom half, but it sees bh->scheduled = 1 and does nothing. This causes
a lost wakeup. The memory barrier should have been changed to smp_mb()
in commit 924fe12 (aio: fix qemu_bh_schedule() bh->ctx race condition,
2014-06-03) together with qemu_bh_schedule()'s. Guess who reviewed
that patch?
Both of these involve a store and a load, so they are reproducible on
x86_64 as well. It is however much easier on aarch64, where the
libguestfs test suite triggers the bug fairly easily. Even there the
failure can go away or appear depending on compiler optimization level,
tracing options, or even kernel debugging options.
Paul Leveille however reported how to trigger the problem within 15
minutes on x86_64 as well. His (untested) recipe, reproduced here
for reference, is the following:
1) Qcow2 (or 3) is critical – raw files alone seem to avoid the problem.
2) Use “cache=directsync” rather than the default of
“cache=none” to make it happen easier.
3) Use a server with a write-back RAID controller to allow for rapid
IO rates.
4) Run a random-access load that (mostly) writes chunks to various
files on the virtual block device.
a. I use ‘diskload.exe c:25’, a Microsoft HCT load
generator, on Windows VMs.
b. Iometer can probably be configured to generate a similar load.
5) Run multiple VMs in parallel, against the same storage device,
to shake the failure out sooner.
6) IvyBridge and Haswell processors for certain; not sure about others.
A similar patch survived over 12 hours of testing, where an unpatched
QEMU would fail within 15 minutes.
This bug is, most likely, also the cause of failures in the libguestfs
testsuite on AArch64.
Thanks to Laszlo Ersek for initially reporting this bug, to Stefan
Hajnoczi for suggesting closer examination of qemu_bh_schedule, and to
Paul for providing test input and a prototype patch.

virtio-blk: correctly dirty guest memory
After qemu_iovec_destroy, the QEMUIOVector's size is zeroed and
the zero size ultimately is used to compute virtqueue_push's len
argument. Therefore, reads from virtio-blk devices did not
migrate their results correctly. (Writes were okay).
Save the size in virtio_blk_handle_request, and use it when the request
is completed.

qcow2: Fix header update with overridden backing file
In recent qemu versions, it is possible to override the backing file
name and format that is stored in the image file with values given at
runtime. In such cases, the temporary override could end up in the
image header if the qcow2 header was updated, while obviously correct
behaviour would be to leave the on-disk backing file path/format
unchanged.
