[Qemu-devel] [PULL 01/18] block: reintroduce bdrv_flush_all

[Kevin Wolf]

From: John Snow <jsnow@redhat.com>

Commit fe1a9cbc moved the flush_all routine from the bdrv layer to the
block-backend layer. In doing so, however, the semantics of the routine
changed slightly such that flush_all now used blk_flush instead of
bdrv_flush.

blk_flush can fail if the attached device model reports that it is not
"available," (i.e. the tray is open.) This changed the semantics of
flush_all such that it can now fail for e.g. open CDROM drives.

Reintroduce bdrv_flush_all to regain the old semantics without having to
alter the behavior of blk_flush or blk_flush_all, which are already
'doing the right thing.'

[Qemu-devel] [PULL 02/18] qemu: use bdrv_flush_all for vm_stop et al

[Kevin Wolf]

From: John Snow <jsnow@redhat.com>

Reimplement bdrv_flush_all for vm_stop. In contrast to blk_flush_all,
bdrv_flush_all does not have device model restrictions. This allows
us to flush and halt unconditionally without error.

This allows us to do things like migrate when we have a device with
an open tray, but has a node that may need to be flushed, or nodes
that aren't currently attached to any device and need to be flushed.

Specifically, this allows us to migrate when we have a CDROM with
an open tray.

[Qemu-devel] [PULL 03/18] block-backend: remove blk_flush_all

[Kevin Wolf]

From: John Snow <jsnow@redhat.com>

We can teach Xen to drain and flush each device as it needs to, instead
of trying to flush ALL devices. This removes the last user of
blk_flush_all.

The function is therefore removed under the premise that any new uses
of blk_flush_all would be the wrong paradigm: either flush the single
device that requires flushing, or use an appropriate flush_all mechanism
from outside of the BlkBackend layer.

[Qemu-devel] [PULL 07/18] block/qapi: Move 'aio' option to file driver

[Kevin Wolf]

The option whether or not to use a native AIO interface really isn't a
generic option for all drivers, but only applies to the native file
protocols. This patch moves the option in blockdev-add to the
appropriate places (raw-posix and raw-win32).

We still have to keep the flag BDRV_O_NATIVE_AIO for compatibility
because so far the AIO option was usually specified on the wrong layer
(the top-level format driver, which didn't even look at it) and then
inherited by the protocol driver (where it was actually used). We can't
forbid this use except in new interfaces.

Amongst others, this means that you can now use the 'detect-zeroes'
option for non-top-level nodes in blockdev-add, like the QAPI schema
promises.

[Kevin Wolf]

Instead of modifying the new BDS after it has been opened, use the newly
supported 'detect-zeroes' option in bdrv_open_common() so that all
requirements are checked (detect-zeroes=unmap requires discard=unmap).

[Qemu-devel] [PULL 10/18] block: Move 'discard' option to bdrv_open_common()

[Kevin Wolf]

This enables its use for nested child nodes. The compatibility
between the 'discard' and 'detect-zeroes' setting is checked in
bdrv_open_common() now as the former setting isn't available before
calling bdrv_open() any more.

[Qemu-devel] [PULL 11/18] block: Remove qemu_root_bds_opts

[Kevin Wolf]

The remaining options in qemu_root_bds_opts (aio and copy-on-read)
aren't used any more, the QAPI schema doesn't contain them. Therefore
all the code processing qemu_root_bds_opts options is dead and can be
removed.

[Qemu-devel] [PULL 12/18] oslib-posix: add helpers for stack alloc and free

[Kevin Wolf]

From: Peter Lieven <pl@kamp.de>

the allocated stack will be adjusted to the minimum supported stack size
by the OS and rounded up to be a multiple of the system pagesize.
Additionally an architecture dependent guard page is added to the stack
to catch stack overflows.

[Qemu-devel] [PULL 18/18] coroutine: reduce stack size to 60kB

[Kevin Wolf]

From: Peter Lieven <pl@kamp.de>

evaluation with the recently introduced maximum stack usage monitoring revealed
that the actual used stack size was never above 4kB so allocating 1MB stack
for each coroutine is a lot of wasted memory. So reduce the stack size to
60kB which should still give enough head room. The guard page added
in qemu_alloc_stack will catch a potential stack overflow introduced
by this commit. The 60kB + guard page will result in an allocation of
64kB per coroutine on systems where a page is 4kB.

I asked on IRC, but as you don't seem to be around at the moment, I'll
keep things on the list instead.

Can you tell me the exact 'configure' and 'make check' command lines
you're using? I always run the tests with clang/Linux on x86_64 before
sending a pull request, and I repeated it now, but the tests pass for
me.

This is what I'm doing (yesterday I built all targets, today only
i386-softmmu because that seems to be what fails for you):

$ clang --version
clang version 3.4.2 (tags/RELEASE_34/dot2-final)
Target: x86_64-redhat-linux-gnu
Thread model: posix
$ ../qemu/configure --cc=clang --host-cc=clang --cxx=clang++ --target-list=i386-softmmu
$ make -j4
$ make check

This is with Ubuntu Xenial's clang. configure args are

'--cc=clang' '--cxx=clang++' '--enable-gtk'
'--extra-cflags=-fsanitize=undefined -Werror'

and the build is just 'make all -j8 && make check' in the build
directory.

Thanks, Peter, this is useful.

The series contains a patch that reduces the coroutine stack size, so I
guess it's not quite infinite, but pretty deep recursion anyway. I will
drop that final patch that reduces the stack size and hope that the rest
will pass your testing (I tried some more to reproduce it, but I still
didn't manage to).

John, can you have a look at the IDE code and check whether we can get
rid of the deep recursion? It seems that the test issues a large request
that is then split into many small requests. But it should be possible
to do this iteratively rather than recursively.

Kevin

Guess I have to float this one to the top.

Ah, I see. I suspect the clang build (since it has the sanitizer
enabled) is a worst-case for stack usage.

Is it possible for a guest to issue a sufficiently large
request that it blows the stack, or is that capped
somehow?

Would it be enough to hide the call to s->bus->dma->ops->start_transfer
behind a bottom half?

Probably the simplest way, even if not the prettiest.

If the qtest can blow the stack, so can a guest. In practice it does not 
happen that guests send requests so large, but mum's the word on a 
naughty guest.

Seems this change makes libvirt not see the discard option any more,
"virsh start" throws this error now ...

error: Failed to start domain fedora-org-xhci
