Another motivation to use ftrace for testing is that it does not
affect the performance in production.
We should keep klp_ftrace_handler() as fast as possible so that we
could livepatch also performance sensitive functions.

Why not use the same terms and design decisions that the C code has? To
differ needs to have a good reason, otherwise it's just going to cause
us all confusion as we have to learn two different terms for the same
thing.

Wait, why can't you have a static "rust_driver" type thing? Having it
be in ram feels like a waste of memory. We are working hard to move
more and more of these driver model structures into read-only memory for
good reasons (security, reduce bugs, etc.), moving backwards to having
them all be dynamically created/copied around feels wrong.
We are one stage away from being able to mark all 'driver_*()' calls as
using a const * to struct driver, please don't make that work pointless
if you want to write a driver in rust instead.
And again, a driver should never know/care/wonder if it has been
registered or not, that is up to the driver core to handle, not the rust
code, as it is the only thing that can know this, and the only thing
that should need to know it. A driver structure should not have any
dynamic memory associated with it to require knowing its "state" in the
system, so let's not move backwards here to require that just because we
are using Rust.

Again, this should not be needed. If so, something is designed

Then all of that should be in a separate file as they belong to a "bus"
not a driver, as each and every bus will have a different way of
expressing the list of devices a driver can bind to.
And again, the core "struct device_driver" does not have a list of ids,
and neither should the rust bindings, that belongs to the bus logic.

A lifecycle of a device is:
device create by the bus
device register with driver core
device bind to a driver (i.e. probe() callback in the driver)
device unbind from a driver (i.e. remove() callback in the driver, can be triggered many ways)
device destroy by the bus
"remove" can happen for a driver where it needs to clean up everything
it has done for a specific device, but that does not mean the device is
actually gone from the system, that's up to the bus to decide, as it
owns the device lifecycle and gets to decide when it thinks it is really
gone. And then, when the bus tells the driver core that it wants to
mark the device as "destroyed", it's up to the driver core to eventually
call back into the bus to really clean that device up from the system at
some later point in time.
Try splitting this file out into driver and bus and device logic, like
the driver core has, and see if that helps in explaining and making all
of this more understandable, and to keep with the names/design of the
model we currently have.
Note, all of this is my biggest worry about writing a driver in rust,
getting the lifecycle of the driver core and it's logic of how it
handles memory manged in C, to align up with how rust is going to access
it with its different rules and requirements, is not going to be simple
as you have two different models intersecting at the same place. I've
been working over the past year to make the rust side happen easier by
marking more and more of the C structures as "not mutable", i.e. const
*, so that the Rust side doesn't have to worry that the driver core
really will change things it passes to the C side, but there is more to
be done (see above about making struct device_driver * const).
I want to see this happen, but it's going to be a hard slog due to the
different expectations of these two systems. Keeping naming identical
where possible is one way to make it simpler for everyone involved, as
would splitting the logic out the same way and not mixing it all up into
one big hairy file that combines different things into a single chunk.

Justified questions – it is public because the Drop implementation for
pci::Bar requires the ioptr to pass it to pci_iounmap().
The alternative would be to give pci::Bar a copy of ioptr (it's just an
integer after all), but that would also not be exactly beautiful.
The subsystem (as PCI does here) shall not make an instance of IoMem
mutable, so the driver programmer couldn't modify ioptr.
I'm very open for ideas for alternatives, though. See also the other
mail where Danilo brainstorms about making IoMem a trait.

Only if IoMem is mutable, correct?
The commit message states (btw this file would get more extensive
comments soonish) that with this design its the subsystem that is
responsible for creating IoMem validly, because the subsystem is the
one who knows about the memory regions and lengths and stuff.
The driver should only ever take an IoMem through a subsystem, so that
would be safe.
> One could

Yes, if the addition violates the capacity of a usize. But that would
then be a bug we really want to notice, wouldn't we?
Only alternative I can think of would be to do a wrapping_add(), but
that would be even worse UB.
Ideas?

Yes, we're aware of that one. We also did some experiments with it.

* [PATCH] mm/hugetlb: Move vmf_anon_prepare upfront in hugetlb_wp

hugetlb_wp calls vmf_anon_prepare() after having allocated a page, which
means that we might need to call restore_reserve_on_error() upon error.
vmf_anon_prepare() releases the vma lock before returning, but
restore_reserve_on_error() expects the vma lock to be held by the caller.
Fix it by calling vmf_anon_prepare() before allocating the page.
Signed-off-by: Oscar Salvador <osalvador@suse.de>
Fixes: 9acad7ba3e25 ("hugetlb: use vmf_anon_prepare() instead of anon_vma_prepare()")
---
I did not hit this bug, I just spotted this because I was looking at hugetlb_wp
for some other reason. And I did not want to get creative to see if I could
trigger this so I could get a backtrace.
My assumption is that we could trigger this if 1) this was a shared mapping,
so no anon_vma and 2) we call in GUP code with FOLL_WRITE, which would cause
the FLAG_UNSHARE to be passed, so we will end up in hugetlb_wp().

could you elaborate, please? We use ftrace exactly for this purpose and
our testing process is also more or less automated.

Why?

Yes, but the information you get is limited compared to what is available
now. You would obtain the information that a patched function was called
but ftrace could also give you the context and more.
It would not hurt to add a new attribute per se but I am wondering about
the reason and its usage. Once we have it, the commit message should be
improved based on that.

* [PATCH 1/2] f2fs: fix to do sanity check on F2FS_INLINE_DATA flag in inode during GC

syzbot reports a f2fs bug as below:
------------[ cut here ]------------
kernel BUG at fs/f2fs/inline.c:258!
CPU: 1 PID: 34 Comm: kworker/u8:2 Not tainted 6.9.0-rc6-syzkaller-00012-g9e4bc4bcae01 #0

ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:244
The root cause is: inline_data inode can be fuzzed, so that there may
be valid blkaddr in its direct node, once f2fs triggers background GC
to migrate the block, it will hit f2fs_bug_on() during dirty page
writeback.
Let's add sanity check on F2FS_INLINE_DATA flag in inode during GC,
so that, it can forbid migrating inline_data inode's data block for
fixing.

Just for my clarification:
First index of "data" is updated here with tag and data pointer incremented.
Next comment for continuation

Here we are effectively setting second and third index of original "data" pointer as "data" pointer was incremented earlier.
So second index of original "data" pointer is not touched. Also returning 3rd index pointer of original data pointer
Is that intentional?
Thanks

Besides the issue pointed by the test robot:
Acked-by: Dmitry Vyukov <dvyukov@google.com>
Thanks for fixing this.
This section of code does not rely on reentrancy, right? E.g. one
callback won't wait for completion of another callback?
At some point we started seeing lots of "remote cover enable write
trace failed (errno 17)" errors while running syzkaller. Can these
errors be caused by this issue?

Expand asn1_encode_integer() to variable size integers, meaning that it
will get a blob in big-endian format as integer and length of the blob as
parameters. This is required in order to encode RSA public key modulus.

dt-bindings: remoteproc: qcom,sdm845-adsp-pil: Fix qcom,halt-regs definition (2024-05-06 19:41:38 -0700)
----------------------------------------------------------------
remoteproc updates for v6.10
This makes the remoteproc core rproc_class const.
DeviceTree bindings for a few different Qualcomm remoteprocs are updated
to remove a range of validation warnings/errors. The Qualcomm SMD
binding marks qcom,ipc deprecated, in favor or the mailbox interface.
The TI K3 R5 remoteproc driver is updated to ensure that cores are
powered up in the appropriate order. The driver also see a couple of
fixes related to cleanups in error paths during probe.
The Mediatek remoteproc driver is extended to support the MT8188 SCP
core 1. Support for varying DRAM and IPI shared buffer sizes are
introduced. This together with a couple of bug fixes and improvements to
the driver.
Support for the AMD-Xilinx Versal and Versal-NET platforms are added.
Coredump support and support for parsing TCM information from DeviceTree
is added to the Xilinx R5F remoteproc driver.

Hi all,
Do not add any work intended for v6.11 to your linux-next included
branches until after v6.10-rc1 has been released.
Changes since 20240520:
The refactor-heap tree still had its conflicts against the block tree
for which I dropped the refactor-heap tree.
Non-merge commits (relative to Linus' tree): 2731
2938 files changed, 400487 insertions(+), 52014 deletions(-)
----------------------------------------------------------------------------
I have created today's linux-next tree at
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
(patches at http://www.kernel.org/pub/linux/kernel/next/ ). If you
are tracking the linux-next tree using git, you should not use "git pull"
to do so as that will try to merge the new linux-next release with the
old one. You should use "git fetch" and checkout or reset to the new
master.
You can see which trees have been included by looking in the Next/Trees
file in the source. There is also the merge.log file in the Next
directory. Between each merge, the tree was built with a ppc64_defconfig
for powerpc, an allmodconfig for x86_64, a multi_v7_defconfig for arm
and a native build of tools/perf. After the final fixups (if any), I do
an x86_64 modules_install followed by builds for x86_64 allnoconfig,
powerpc allnoconfig (32 and 64 bit), ppc44x_defconfig, allyesconfig
and pseries_le_defconfig and i386, arm64, s390, sparc and sparc64
defconfig and htmldocs. And finally, a simple boot test of the powerpc
pseries_le_defconfig kernel in qemu (with and without kvm enabled).
Below is a summary of the state of the merge.
I am currently merging 373 trees (counting Linus' and 103 trees of bug
fix patches pending for the current merge release).
Stats about the size of the tree over time can be seen at
http://neuling.org/linux-next-size.html .
Status of my local build tests will be at
http://kisskb.ellerman.id.au/linux-next . If maintainers want to give
advice about cross compilers/configs that work, we are always open to add
more builds.
Thanks to Randy Dunlap for doing many randconfig builds. And to Paul
Gortmaker for triage and bug fixes.

Cheers,
Stephen Rothwell

No disagreement there, I think it's more correct to not propagate
any errors resulting from reclaim failure. Was just explaining why the
original code had propensity for propagating errors to guest, and why it
still needs to be done for firmware errors.

In practice userspace will get an unhandled exit and kill the vcpu/guest,
but we could additionally flag the guest as dead. Is there a existing
mechanism for this?

Yah, the v2 patch will only propagate the firmware error if reclaim was
successful.

The guest side is upstream, and Dionna submitted HV patches last year. I think
these are the latest ones:
https://www.spinics.net/lists/kvm/msg301438.html
I think it probably makes sense to try to get the throttling support in
for 6.11

OK. The point is not to argue about L1 how to handle, but whether we
should inject to L1 -- L1 can do whatever it believes legal/sane.
But I understand the purpose is to test/validate, so it's fine for L0 to
handle, and by handle it eventually means we want to just dump that #VE
exit.
But now L0 always handles #VE exits from L2, and AFAICT L0 will just
kill the L1, until the patch:
KVM: VMX: Don't kill the VM on an unexpected #VE
lands.
So looks that patch at least should be done first. Otherwise it doesn't
make a lot sense to kill L1 for #VE exits from L2.

Yeah. I am not sure the purpose of validating #VE exits from L2.

Not "should never", "can never". If L1 attempts to enable EPT_VIOLATION_VE, then
VM-Enter will VM-Fail.

No. Architecturally, from L1's perspective, a #VE VM-Exit _cannot_ occur in L2.
L1 can inject a #VE into L2, but a #VE cannot be generated by the CPU and thus
cannot cause a VM-Exit.
> Unconditionally disable #VE in vmcs02 can avoid such issue because it's just
> not possible for L2 to have the #VE exit.
Sure, but by that argument we could just avoid all nested VMX issues by never
enabling anything for L2.
If there's an argument to be made for disabling EPT_VIOLATION_VE in vmcs02, it's
that the potential maintenance cost of keeping nEPT, nVMX, and the shadow MMU
healthy outweighs the benefits. I.e. we don't have a use case for enabling
EPT_VIOLATION_VE while L2 is running, so why validate it?
If whatever bug the KUT EPT found ends up being a KVM bug that specifically only
affects nVMX, then it'd be worth revisiting whether or not it's worth enabling
EPT_VIOLATION_VE in vmcs02. But that's a rather big "if" at this point.

* [PATCH net] testing: net-drv: use stats64 for testing
@ 2024-05-20 23:58 2% Joe Damato
0 siblings, 0 replies; 200+ results
From: Joe Damato @ 2024-05-20 23:58 UTC (permalink / raw)

Cc: nalramli, Joe Damato, Shuah Khan, Jakub Kicinski,
David S. Miller, open list:KERNEL SELFTEST FRAMEWORK
Testing a network device that has large numbers of bytes/packets may
overflow. Using stats64 when comparing fixes this problem.
I tripped on this while iterating on a qstats patch for mlx5. See below
for confirmation without my added code that this is a bug.
Before this patch (with added debugging output):
$ NETIF=eth0 tools/testing/selftests/drivers/net/stats.py
KTAP version 1
1..4
ok 1 stats.check_pause
ok 2 stats.check_fec
rstat: 481708634 qstat: 666201639514 key: tx-bytes
not ok 3 stats.pkt_byte_sum
ok 4 stats.qstat_by_ifindex
Note the huge delta above ^^^ in the rtnl vs qstats.
After this patch:
$ NETIF=eth0 tools/testing/selftests/drivers/net/stats.py
KTAP version 1

ok 4 stats.qstat_by_ifindex
It looks like rtnl_fill_stats in net/core/rtnetlink.c will attempt to
copy the 64bit stats into a 32bit structure which is probably why this
behavior is occurring.
To show this is happening, you can get the underlying stats that the
stats.py test uses like this:
$ ./cli.py --spec ../../../Documentation/netlink/specs/rt_link.yaml \
--do getlink --json '{"ifi-index": 7}'
And examine the output (heavily snipped to show relevant fields):
'stats': {
'multicast': 3739197,
'rx-bytes': 1201525399,
'rx-packets': 56807158,
'tx-bytes': 492404458,
'tx-packets': 1200285371,
'stats64': {
'multicast': 3739197,
'rx-bytes': 35561263767,
'rx-packets': 56807158,
'tx-bytes': 666212335338,
'tx-packets': 1200285371,
The stats.py test prior to this patch was using the 'stats' structure
above, which matches the failure output on my system.
Comparing side by side, rx-bytes and tx-bytes, and getting ethtool -S
output:
rx-bytes stats: 1201525399
rx-bytes stats64: 35561263767
rx-bytes ethtool: 36203402638
tx-bytes stats: 492404458
tx-bytes stats64: 666212335338
tx-bytes ethtool: 666215360113
Note that the above was taken from a system with an mlx5 NIC, which only
exposes ndo_get_stats64.
Based on the ethtool output and qstat output, it appears that stats.py
should be updated to use the 'stats64' structure for accurate
comparisons when packet/byte counters get very large.
To confirm that this was not related to the qstats code I was iterating
on, I booted a kernel without my driver changes and re-ran the test
which shows the qstats are skipped (as they don't exist for mlx5):
NETIF=eth0 tools/testing/selftests/drivers/net/stats.py
KTAP version 1
1..4
ok 1 stats.check_pause
ok 2 stats.check_fec
ok 3 stats.pkt_byte_sum # SKIP qstats not supported by the device
ok 4 stats.qstat_by_ifindex # SKIP No ifindex supports qstats
But, fetching the stats using the CLI
$ ./cli.py --spec ../../../Documentation/netlink/specs/rt_link.yaml \
--do getlink --json '{"ifi-index": 7}'
Shows the same issue (heavily snipped for relevant fields only):
'stats': {
'multicast': 105489,
'rx-bytes': 530879526,
'rx-packets': 751415,
'tx-bytes': 2510191396,
'tx-packets': 27700323,
'stats64': {
'multicast': 105489,
'rx-bytes': 530879526,
'rx-packets': 751415,
'tx-bytes': 15395093284,
'tx-packets': 27700323,
Comparing side by side with ethtool -S on the unmodified mlx5 driver:
tx-bytes stats: 2510191396
tx-bytes stats64: 15395093284
tx-bytes ethtool: 17718435810

I think the key word above is "exploited", implying some sort of
unauthorised action.
This bug can cause the system to not boot, but only by someone who
builds a new kernel and installs it - and if they have permission to do
that they can just replace the kernel with anything, they don't need a
bug.

Yes please.

KEYS: trusted: Do not use WARN when encode fails (2024-05-21 02:35:10 +0300)
----------------------------------------------------------------
Hi,
These are couple of bugs I found from trusted keys while working on a new
asymmetric key type for TPM2 [1]. Both originate form v5.13. Memory leak is
more crucial but I don't think it is either good idea if kernel throws WARN
when ASN.1 parser fails, even if it is related to programming error, as it
is not that mature code yet.
There's at least two WARN's in that code but I picked just the one more
likely to trigger. Planning to fix the other one too over time.
BR, Jarkko

But failure to convert a pfn back to shared is a _host_ issue, not a guest issue.
E.g. it most likely indicates a bug in the host software stack, or perhaps a bad
CPU or firmware bug.

I was thinking more along the lines of KVM marking the VM as dead/bugged.

If and only the hypervisor completes the event.
The hypervisor must save the SNP_GUEST_REQUEST return code in the lower 32-bits
of the SW_EXITINFO2 field before completing the Guest Request NAE event.
If KVM terminates the VM, there's obviously no need to fill SW_EXITINFO2.
Side topic, is there a plan to ratelimit Guest Requests?
To avoid the possibility of a guest creating a denial of service attack against
the SNP firmware, it is recommended that some form of rate limiting be implemented
should it be detected that a high number of Guest Request NAE events are being
issued.

I get this regardless building with GCC 13.2 or CLANG 18 (https://github.com/ClangBuiltLinux/linux/issues/2020). Nathan also found out the test fails when the machine has more than 867 MB of RAM.
In the original upstream discussion (https://lore.kernel.org/linux-mm/CA+fCnZeeJub5iCwwwGM2pDt9wzX=T4+wpZbbGhKQ7Qbtb+tFeA@mail.gmail.com/#t) Andrey suggested to open a separate thread pointing out the issue could originate in vmalloc issues.

The issue can also be seen on qemu. I run my attached .config kernel build on via: qemu-system-ppc -machine mac99,via=pmu -cpu 7450 -m 2G -nographic -append console=ttyS0 -kernel /var/cache/distfiles/vmlinux-6.9.1-PMacG4-dirty -hda Debian-VM_g4.img

Right, looks like we don't currently have UBSan instrumentation for "I
modified an object declared const." Instead, it just leads to fun
bugs like "why was my write elided" or in this case "why did my
constant folding change between compiler versions?" Such are the joys
of UB.

Wouldn't it be more user-friendly if this check would be left out? Does any code
depend on max_copy_bytes being a multiple of the logical block size?

queue_copy_max_show() shows max_copy_sectors while queue_copy_max_store()
modifies max_user_copy_sectors. Is that perhaps a bug?

Two new limits are documented in Documentation/ABI/stable/sysfs-block while three
new parameters are added in struct queue_limits. Why three new limits instead of
two? Please add a comment above the new parameters that explains the role of the
new parameters.
> +/* maximum copy offload length, this is set to 128MB based on current testing */

"current testing" sounds vague. Why is this limit required? Why to cap what the
driver reports instead of using the value reported by the driver without modifying it?
Additionally, since this constant is only used in source code that occurs in the
block/ directory, please move the definition of this constant into a source or header
file in the block/ directory.
Thanks,
Bart.

arch: Fix name collision with ACPI's video.o (2024-05-20 21:17:06 +0000)
----------------------------------------------------------------
asm-generic cleanups for 6.10
These are a few cross-architecture cleanup patches:
- Thomas Zimmermann works on separating fbdev support from the asm/video.h
contents that may be used by either the old fbdev drivers or the
newer drm display code.
- Thorsten Blum contributes cleanups for the generic bitops code
and asm-generic/bug.h
- I remove the orphaned include/asm-generic/page.h header that used to
included by long-removed mmu-less architectures.
------------
I finally managed to resend this pull request after
merging another regression fix for the original
contents that were missing the tag on git.kernel.org
during my travels.
----------------------------------------------------------------

* [PATCH] kcov, usb: disable interrupts in kcov_remote_start_usb_softirq

From: Andrey Konovalov <andreyknvl@gmail.com>
After commit 8fea0c8fda30 ("usb: core: hcd: Convert from tasklet to BH
workqueue"), usb_giveback_urb_bh() runs in the BH workqueue with
interrupts enabled.
Thus, the remote coverage collection section in usb_giveback_urb_bh()->
__usb_hcd_giveback_urb() might be interrupted, and the interrupt handler
might invoke __usb_hcd_giveback_urb() again.
This breaks KCOV, as it does not support nested remote coverage collection
sections within the same context (neither in task nor in softirq).
Update kcov_remote_start/stop_usb_softirq() to disable interrupts for the
duration of the coverage collection section to avoid nested sections in
the softirq context (in addition to such in the task context, which are
already handled).

I have around 50 hosts handling high I/O (each with 20Gbps+ uplinks
and multiple NVMe drives), running RockyLinux 8/9. The stock RHEL
kernel 8/9 is NOT affected, and the long-term kernel 5.15.X is NOT affected.
However, with long-term kernels 6.1.XX and 6.6.XX,
(tested at least 10 different versions), this lockup always appears
after 2-30 days, similar to the report in the original thread.
The more load (for example, copying a lot of local files while
serving 20Gbps traffic), the higher the chance that the bug will appear.
I haven't been able to reproduce this during synthetic tests,
but it always occurs in production on 6.1.X and 6.6.X within 2-30 days.
If anyone can provide a patch, I can test it on multiple machines
over the next few days.
Regards,
Marcin

^^^^^^^^^^^^^^^^
This is a gross way to handle anonymous struct fields. What happens
when struct inode changes and we have to do a giant treewide sed?
(and yes, I understand that's likely going to be a rustc change...)

Hi Linus,
Could you please consider this pull reuqest?
Thanks,
The following changes since commit 928a87efa42302a23bb9554be081a28058495f22:
Merge tag 'gfs2-v6.8-fix' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2 (2024-03-25 10:53:39 -0700)

f2fs: initialize last_block_in_bio variable (2024-05-15 04:18:40 +0000)
----------------------------------------------------------------
f2fs update for 6.10-rc1
In this round, we've tried to address some performance issues on zoned storage
such as direct IO and write_hints. In addition, we've migrated some IO paths
using folio. Meanwhile, there are multiple bug fixes in the compression paths,
sanity check conditions, and error handlers.
Enhancement:
- allow direct io of pinned files for zoned storage
- assign the write hint per stream by default
- convert read paths and test_writeback to folio
- avoid allocating WARM_DATA segment for direct IO
Bug fix:
- fix false alarm on invalid block address
- fix to add missing iput() in gc_data_segment()
- fix to release node block count in error path of f2fs_new_node_page()
- compress: don't allow unaligned truncation on released compress inode
- compress: fix to cover {reserve,release}_compress_blocks() w/ cp_rwsem lock
- compress: fix error path of inc_valid_block_count()
- compress: fix to update i_compr_blocks correctly
- fix block migration when section is not aligned to pow2
- don't trigger OPU on pinfile for direct IO
- fix to do sanity check on i_xattr_nid in sanity_check_inode()
- write missing last sum blk of file pinning section
- clear writeback when compression failed
- fix to adjust appropirate defragment pg_end
As usual, there are several minor code clean-ups, and fixes to manage missing
corner cases in the error paths.
----------------------------------------------------------------

f2fs: support .shutdown in f2fs_sops
f2fs: fix to detect inconsistent nat entry during truncation

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying

When asn1_encode_sequence() fails, WARN is not the correct solution.
1. asn1_encode_sequence() is not an internal function (located
in lib/asn1_encode.c).
2. Location is known, which makes the stack trace useless.
3. Results a crash if panic_on_warn is set.
It is also noteworthy that the use of WARN is undocumented, and it
should be avoided unless there is a carefully considered rationale to
use it.
Replace WARN with pr_err, and print the return value instead, which is
only useful piece of information.

'scratch' is never freed. Fix this by calling kfree() in the success, and
in the error case.

* [PATCH 0/3] Resolve problems with kexec identity mapping

Although there was a previous fix to avoid early kernel access to the
EFI config table on Intel systems, the problem can still exist on AMD
systems that support SEV (Secure Encrypted Virtualization). The
command line option "nogbpages" brings this bug to the surface. And
this is what caused the regression with my earlier patch that
attempted to reduce the use of gbpages. This patch series fixes that
problem and restores my earlier patch.
The following 2 commits caused the EFI config table, and the CC_BLOB
entry in that table, to be accessed when enabling SEV at kernel
startup.
commit ec1c66af3a30 ("x86/compressed/64: Detect/setup SEV/SME features
earlier during boot")
commit c01fce9cef84 ("x86/compressed: Add SEV-SNP feature
detection/setup")
These accesses happen before the new kernel establishes its own
identity map, and before establishing a routine to handle page faults.
But the areas referenced are not explicitly added to the kexec
identity map.
This goes unnoticed when these areas happen to be placed close enough
to others areas that are explicitly added to the identity map, but
that is not always the case.
Under certain conditions, for example Intel Atom processors that don't
support 1GB pages, it was found that these areas don't end up mapped,
and the SEV initialization code causes an unrecoverable page fault,
and the kexec fails.
Tau Liu had offered a patch to put the config table into the kexec
identity map to avoid this problem:
https://lore.kernel.org/all/20230601072043.24439-1-ltao@redhat.com/
But the community chose instead to avoid referencing this memory on
non-AMD systems where the problem was reported.
commit bee6cf1a80b5 ("x86/sev: Do not try to parse for the CC blob
on non-AMD hardware")
I later wanted to make a different change to kexec identity map
creation, and had this patch accepted:
commit d794734c9bbf ("x86/mm/ident_map: Use gbpages only where full GB page should be mapped.")
but it quickly needed to be reverted because of problems on AMD systems.
The reported regression problems on AMD systems were due to the above
mentioned references to the EFI config table. In fact, on the same
systems, the "nogbpages" command line option breaks kexec as well.
So I resubmit Tau Liu's original patch that maps the EFI config
table, add an additional patch by me that ensures that the CC blob is
also mapped (if present), and also resubmit my earlier patch to use
gpbages only when a full GB of space is requested to be mapped.
I do not advocate for removing the earlier, non-AMD fix. With kexec,
two different kernel versions can be in play, and the earlier fix
still covers non-AMD systems when the kexec'd-from kernel doesn't have
these patches applied.
All three of the people who reported regression with my earlier patch
have retested with this patch series and found it to work where my
single patch previously did not. With current kernels, all fail to
kexec when "nogbpages" is on the command line, but all succeed with
"nogbpages" after the series is applied.
Tao Liu (1):
x86/kexec: Add EFI config table identity mapping for kexec kernel
Steve Wahl (2):
x86/kexec: Add EFI Confidential Computing blob to kexec identity
mapping.
x86/mm/ident_map: Use gbpages only where full GB page should be
mapped.

Expand asn1_encode_integer() to variable size integers, meaning that it
will get a blob in big-endian format as integer and length of the blob as
parameters. This is required in order to encode RSA public key modulus.

Hmm, that should have been fixed with this pull request:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e92b99ae8216dec2566711dae0a9b7b47591e315
Let me know if you have that, and if so, please send me your config.
Oh, and make sure that you have the latest selftests running too.
Thanks,

This is a list of bugs being fixed. The bug was a panic, the fix is
stop decoding.
Likewise, the other fix is not adding a KCFI violation.
Thanks for making my day :-D
Joke apart, I thought it was clear enough, but I take note to word
things differently next time.

Hi Steven,
If I execute test.d/00basic/test_ownership.tc in a row,
it passes in the first run, and fails in the second run.
I observe this on the Ubuntu 24.04 (6.8 kernel),
and also on the latest linux-next (next-20240520).
Is this a limitation of the test or a kernel bug?
vagrant@debian:~/linux/tools/testing/selftests/ftrace$ sudo

In my case I use the official Thunderbolt cable that came with my
CalDigit TS3 Plus and yet the log - attached in a previous email -
says current link speed 10.0 Gb/s. I just tried a good quality USB4
cable too and nothing changed.
Maybe it's relevant to note that I'm using the Thunderbolt dock via
USB4 on a PC with an AMD Ryzen 7 7735HS.

Add an (always) reference counted abstraction for a generic struct
device. This abstraction encapsulates existing struct device instances
and manages its reference count.
Subsystems may use this abstraction as a base to abstract subsystem
specific device instances based on a generic struct device.

Possibly this is because the driver's probe function doesn't clean up
itself properly if it fails in the middle (e.g. due to the system running
out of memory and kmalloc() fails). These aren't easy to reproduce, because
you would need to make probing fails somehow.
Example fix: ac83631230f7 ("staging: r8712: Fix memory leak in
_r8712_init_xmit_priv()")

To keep the log small I unplugged all USB devices from the dock.
But even if connected I don't have issues with them.

Exactly only the second monitor is/was not working.

My dock is a little different model (see https://www.caldigit.com/usb-c-pro-dock/)
I don't have a CalDigit TS3 Plus.

The dock was connected with a Thunderbolt cable, that I used for a couple of years without any issues.
Based on the hint I replaced the cable and the issue is now gone for me.
I still don't understand why this happened as it was working great for years and is still working with kernels 6.8.7 or older.
But nevertheless sorry if I wasted time of anyone because of broken hardware.

Yup, I think it'd be better to have a patch per issue to attack the exact
problem.

Well, I wasn't going to pull that based on the description, but it
turns out it's not a panic at all, it's just a "stop decoding".
Because panicking on broken firmware would be horrible.

May I ask why is this classified a CVE?
How can a malicious user exploit this to do something harmful?
The race was solved to silence KCSAN warnings, as from time to time we have
someone reporting it, but other than that, it should be harmless.
Thanks.

All the USB devices seem to work fine (assuming I read this right).
There is the DP tunneling limitation but other than that how the dock
does not work? At least reading this log everything else seems to be
fine except the second monitor?
Now it is interesting why the link is only 20G and not 40G. I do have
this same device and it gets the link up as 40G just fine:
[ 17.867868] thunderbolt 0000:00:0d.2: 1: current link speed 20.0 Gb/s
[ 17.867869] thunderbolt 0000:00:0d.2: 1: current link width symmetric, single lane
[ 17.868437] thunderbolt 0000:00:0d.2: 0:1: total credits changed 120 -> 60
[ 17.868625] thunderbolt 0000:00:0d.2: 0:2: total credits changed 0 -> 60
[ 17.872472] thunderbolt 0000:00:0d.2: 1: TMU: current mode: bi-directional, HiFi
[ 17.872608] thunderbolt 0-1: new device found, vendor=0x3d device=0x11
[ 17.879102] thunderbolt 0-1: CalDigit, Inc. TS3 Plus
Do you use a Thunderbolt cable or some regular type-C one? There is the
lightning symbol on the connector when it is Thunderbolt one.

you still don't say what problem not posting most patches solves? You
imply it would slow you down, but getting git-send-email to post to a
mailing list can actually be automated through a pre-push commit hook
with no slowdown in the awesome rate at which you apply patches to your
own tree.
Linux kernel process exists because it's been found to work over time.
That's not to say it can't be changed, but it usually requires at least
some stab at a reason before that happens.

These are echo chamber reviews. Even if you echo chamber happens
produce good reviews there's still no harm in getting them from outside
it as well. Plus we can't make this generic workflow because too many
less awesome contributors would take advantage of the laxity it offers.

Just because you won't check others' code for bugs doesn't mean that

This is an unknown unknown problem: you can't bring up to others things

So you didn't answer whether you ran checkpatch and ignored the warning
(in which case a commit comment explaining why would have been useful)
or didn't run checkpatch (in which case why not?).

I attached the requested kernel logs as text files (hope this is ok).
In both cases I used the stable ArchLinux kernel 6.9.1
The iommu_dma_protection is both cases "1".

All this is showing is that the switch downstream ports on bus 0004:02
have a slot capability. I already know that (see what I said
previously about physical links). The fact the downstream ports have a
slot capability also has absolutely nothing to do with anything I was
saying. Look at the lspci output for 0004:01:00.0 which is the
switch's upstream port. The upstream port device will not have a slot
capability because it's a bridge into the virtual PCI bus that is
internal to the switch.

The point of this series is to fix the behaviour of pnv_php, is it
not? Powering off a PCI(e) slot is supposed to render it safe to
remove the card in that slot. Currently if you "power off" C5, the
kernel is still going to have active references to the switch's
upstream port device (at 0004:01:00.0) and the switch management
function (at 0004:01:00.1). If the kernel has active references to PCI
devices physically located in the slot we supposedly powered off, then
the hotplug driver isn't doing its job. The asymmetry between hot add
and removal that you're trying to fix here is a side effect of the
fact that pnv_php is advertising the wrong thing as a slot. I think
you should stop pnv_php from advertising something as a slot when it's
not actually a slot because that's the root of all your problems.

Right, as I said above I don't think handing the more generic case is
actually required if pnv_php is doing its job properly. It doesn't
hurt though.

I already read your patch so I'm not sure why you feel the need to
re-describe it in tedious detail.

Yes, do that.
Also, do not post HTML emails to linux development lists. It breaks
plain text inline quoting which makes your messages annoying to reply
to. Some linux development lists will also silently drop HTML emails.
Please talk to the other LTC engineers about how to set up your mail
client to send plain text emails to avoid these problems in the
future.

I am inclined to think that this issue might be false positive. During
repro the device is initialized correctly, does some work and then
exits, calling all required functions to clean things up
(i.e. _free_xmit_priv()), including pxmitbuf->pallocated_buf.
Kmemleak triggers disappear if you set longer intervals between
scannning for them (obviously). And if all the things get cleared up
when the device disconnects, isn't that correct and expected
behaviour? Could the scanner just "lose track" of some of the objects
here?
Or am I missing something?
Regards,
Nikita

You're right, that phrase was awkward in the direct translation. Thanks
for catching that.

I will send version 2 patch. Thank you!

* [PATCH v2] arm64: asm-bug: Add .align 2 to the end of __BUG_ENTRY

When CONFIG_DEBUG_BUGVERBOSE=n, we fail to add necessary padding bytes
to bug_table entries, and as a result the last entry in a bug table will
be ignored, potentially leading to an unexpected panic(). All prior
entries in the table will be handled correctly.
The arm64 ABI requires that struct fields of up to 8 bytes are
naturally-aligned, with padding added within a struct such that struct
are suitably aligned within arrays.
When CONFIG_DEBUG_BUGVERPOSE=y, the layout of a bug_entry is:
struct bug_entry {
signed int bug_addr_disp; // 4 bytes
signed int file_disp; // 4 bytes
unsigned short line; // 2 bytes
unsigned short flags; // 2 bytes
}
... with 12 bytes total, requiring 4-byte alignment.
When CONFIG_DEBUG_BUGVERBOSE=n, the layout of a bug_entry is:
struct bug_entry {
signed int bug_addr_disp; // 4 bytes
unsigned short flags; // 2 bytes
< implicit padding > // 2 bytes
}
... with 8 bytes total, with 6 bytes of data and 2 bytes of trailing
padding, requiring 4-byte alginment.
When we create a bug_entry in assembly, we align the start of the entry
to 4 bytes, which implicitly handles padding for any prior entries.
However, we do not align the end of the entry, and so when
CONFIG_DEBUG_BUGVERBOSE=n, the final entry lacks the trailing padding
bytes.
For the main kernel image this is not a problem as find_bug() doesn't
depend on the trailing padding bytes when searching for entries:
for (bug = __start___bug_table; bug < __stop___bug_table; ++bug)
if (bugaddr == bug_addr(bug))
return bug;
However for modules, module_bug_finalize() depends on the trailing
bytes when calculating the number of entries:
mod->num_bugs = sechdrs[i].sh_size / sizeof(struct bug_entry);
... and as the last bug_entry lacks the necessary padding bytes, this entry
will not be counted, e.g. in the case of a single entry:
sechdrs[i].sh_size == 6
sizeof(struct bug_entry) == 8;
sechdrs[i].sh_size / sizeof(struct bug_entry) == 0;
Consequently module_find_bug() will miss the last bug_entry when it does:
for (i = 0; i < mod->num_bugs; ++i, ++bug)
if (bugaddr == bug_addr(bug))
goto out;
... which can lead to a kenrel panic due to an unhandled bug.
This can be demonstrated with the following module:
static int __init buginit(void)
{
WARN(1, "hello\n");
return 0;
}
static void __exit bugexit(void)
{
}
module_init(buginit);
module_exit(bugexit);
MODULE_LICENSE("GPL");
... which will trigger a kernel panic when loaded:

Thanks for translating new Documentation/process/cve document to Korean
Language. Most of the Korean sentences are looks good to me. But only
one sentence seemed unnatural.

When the first modifier "해당" is first used in a Korean sentence, like
"the", there needs to be an explanation of what it is targeting.
However, in the process of literal translation, it seems that "the"
became "해당" due to the difference in word order between Korean and
English, And since the translated sentence did not describe which "Linux
distributor" is being described, it would be very difficult if
"특정(specific)" were used instead. It seems natural.

Putting my RT hat on, I really don't like the above fix. The
rb_check_pages() iterates all subbuffers which makes the time interrupts
are disabled non-deterministic.
Instead, I would rather have something where we disable readers while we do
the check, and re-enable them.
raw_spin_lock_irqsave(&cpu_buffer->reader_lock, flags);
cpu_buffer->read_disabled++;
raw_spin_unlock_irqrestore(&cpu_buffer->reader_lock, flags);
// Also, don't put flags on a new line. We are allow to go 100 characters now.
rb_check_pages(cpu_buffer);
raw_spin_lock_irqsave(&cpu_buffer->reader_lock, flags);
cpu_buffer->read_disabled--;
raw_spin_unlock_irqrestore(&cpu_buffer->reader_lock, flags);
Or something like that. Yes, that also requires creating a new
"read_disabled" field in the ring_buffer_per_cpu code.
That said, I'm going to accept these patches as is (moving flags onto the
same line). But would like the above code for the next merge window as it
would then not affect RT.
I'll accept these patches because it does fix the bug now.

Thank you very much for your patience and professional review.
Indeed, we have not clearly expressed the specific layout
of `struct bug_entry` under the arm64 ABI
and how it causes the problem. We have only briefly described
that the assembly code does not consistent with
the binary layout of the C struct.
Your commit messge is much more accurate
in describing the problem, and we couldn't agree more.
I will follow your advice to submit our V2 patch.

It fixes a problem like an oops, a hang, data corruption, a real
security issue, a hardware quirk, a build error (but not for things
marked CONFIG_BROKEN), or some “oh, that’s not good” issue.
Your description of the very first message transfer failing sounds
like a data corruption? Using the commit which adds the driver is also
fine, some bugs have been there all the time.

To: Andrew Morton; +Cc: linux-nilfs, syzbot, syzkaller-bugs, linux-kernel, sjb7183
Syzbot has reported a potential hang in nilfs_detach_log_writer()
called during nilfs2 unmount.
Analysis revealed that this is because nilfs_segctor_sync(), which
synchronizes with the log writer thread, can be called after
nilfs_segctor_destroy() terminates that thread, as shown in the call
trace below:
nilfs_detach_log_writer
nilfs_segctor_destroy
nilfs_segctor_kill_thread --> Shut down log writer thread
flush_work
nilfs_iput_work_func
nilfs_dispose_list
iput
nilfs_evict_inode
nilfs_transaction_commit
nilfs_construct_segment (if inode needs sync)
nilfs_segctor_sync --> Attempt to synchronize with
log writer thread
*** DEADLOCK ***
Fix this issue by changing nilfs_segctor_sync() so that the log writer
thread returns normally without synchronizing after it terminates, and
by forcing tasks that are already waiting to complete once after the
thread terminates.
The skipped inode metadata flushout will then be processed together in
the subsequent cleanup work in nilfs_segctor_destroy().

Hello Andrew,
Please apply this series as bug fixes.
This bug fix series covers three nilfs2 log writer-related issues,
including a timer use-after-free issue and potential deadlock issue on
unmount, and a potential freeze issue in event synchronization found
during their analysis. Details are described in each commit log.
thank you always.

The implementation of risc-v BUG_ENTRY does handle
the `implicit padding` at the end of the struct correctly,
however, it does not handle the `implicit padding` in the middle of
the struct correctly, for example, assume that
the struct bug_entry changes as follows in the future:
struct bug_entry {
signed int bug_addr_disp; // 4 bytes
unsigned short flags; // 2 bytes
< implicit padding > // 6 bytes
unsigned long long flags2; // 8 bytes
}
Even the implementation of risc-v BUG_ENTRY
can't handle this situation. Referencing risc-v solution
complicates things, but doesn't completely solve the problem.
In the current scenario, we know the contents of struct bug_entry
and generate variables using assembly language.
I don't think it's necessary to complicate things.

I can see why that appears nice, but we can't do that in asm-bug.h
without something in asm-offets.h, and I suspect that's going to lead to
pain with circular header dependencies.
Regardless, if things change we'll need to make other changes here, so I
don't think we gain much.
I think it's preferable to have the explicit .align for now.
Mark.

I'm going to start by putting out two reports from dmesg's journal.
This is the complete log of the first boot up of the ARM platform
development board.
：https://paste.ubuntu.com/p/H4Wf88tb6r/
The main problem with this log is that when I just connect to the
internet the kernel log shows ‘[ 145.531887] mtk_t7xx 0000:01:00.0:
CLDMA0 queue 5 is not empty
[ 273.561922] NOHZ tick-stop error: local softirq work is pending,
handler #08!!!’ and the speed is unstable
This log is after the development board performs a reboot.
： https://paste.ubuntu.com/p/CwVVMwkcqD/
The main problem is that wwan0at0 and wwan0mbim0 cannot be generated properly.
This email has been translated from Chinese to English using a
translation tool, and I apologise for any semantic differences.

Sorry just forgot to reply to this！
Yes, after loading the xas, the entry (aka req) is checked to see if it
meets
expectations, and only when it does do we null the xas and complete the
request.

The use of .align 2 here is based on the assumption that struct
bug_entry is 4-byte aligned. Currently, there is no problem with this
assumption, but for compatibility reasons, refer to the riscv
architecture and refactor the implementation of __BUG_FLAGS:
#define __BUG_FLAGS(flags) \
do { \
__asm__ __volatile__ ( \
"1:\n\t" \
"ebreak\n" \
".pushsection __bug_table,\"aw\"\n\t" \

__BUG_ENTRY "\n\t" \
".org 2b + %3\n\t" \
".popsection" \
: \
: "i" (__FILE__), "i" (__LINE__), \
"i" (flags), \
"i" (sizeof(struct bug_entry))); \
} while (0)
Align the real size of struct bug_entry through .org. What do you think?

Sorry to bother you, do you have some suggestions on this topic?
On my side I did some investigation to see how else it could be implemented
but I don't have much clue how to go forward.
Would you prefer to have a separate API to deal with domain power on in
this scenario? Maybe one that should run only in the reboot context?
Would you consider only updating the description of dev_pm_genpd_resume()
and genpd_sync_power_on() to specify that it could run in a reboot context?
Would you consider updating the genpd_switch_state() to take into system
reboot state and do locking based on that, too?

The clock driver doesn't implement clk_ops::prepare in all
micro-architectures that this watchdog driver is used. This may be the
reason the clk_prepare_enable() was used on this path from the beginning.
Even though, a simple solution I have in mind for this is to keep the clk
prepared all the time.

This one prints TDX version info in the TDX guest, but not host.
The attached diff prints the TDX version (something like below) during
module initialization, and should meet Juergen's needs for temporary use:

From this thread I think it makes sense to add code to the TDX host code
to print the TDX version during module initialization. I'll start to work
on this.
One thing is from the spec TDX has "4 versions": major, minor, update,
internal. They are all 16-bit, and the overall version can be written in:
<Major>.<Minor>.<Update>.<Internal>, e.g., 1.5.05.01
(see TDX module 1.5 API spec, section 3.3.2 "TDX Module Version".)
The attached diff only prints major, minor and internal, but leaves the
update out because I believe it is for module runtime update (yet to
confirm).
Given there are 4 versions, I think it makes sense to implement reading
them based on this patchset ...
https://lore.kernel.org/kvm/6940c326-bfca-4c67-badf-ab5c086bf492@intel.com/T/
... which extends the global metadata reading code to support any
arbitrary struct and all element sizes (although all 4 versions are 16-
bit)?

OK. I sent v3 for reviewing first. If v3 patch is fine, I'll send v4
after May 26th.

The warning report is different with the dead-lock syzbot report. The
warning is "WARN_ON_ONCE((gfp_flags & __GFP_NOFAIL) && (order > 1))" in
rmqueue() and it is caused by "kzalloc(sizeof(struct xfs_mount),
GFP_KERNEL | __GFP_NOFAIL)" in xfs_init_fs_context().

I think it is a false positive, because without KASAN enabled, the size
of xfs_mount is about 2496 bytes and it is impossible to trigger the
WARN_ON_ONCE(). However with KASAN enabled, the size of xfs_mount will
be greater than 4096, so the warning will be triggered accordingly when
the 8KB-slab needs to refill its slabs.

The normal lock sequence is trie->lock and then zone->lock, the syzbot
constructs a reversed lock sequence by attaching a bpf program to
trace_contention_end() on zone->lock and calls trie_delete_elem() in the
bpf program, so the dead-lock is indeed possible.
There are two feasible ways to fix the problem:
1) switch from bpf_map_kmalloc_node()/kfree to bpf memory allocator for
lpm trie
2) add a dead-lock checking map just like hash-table does and also need
to make lockdep be happy with the try-lock mechanism.
I prefer 1), but it could not eliminate the dead-lock completely,
because the syzbot may construct a bpf program which invokes
trie_delete_elem(), attach to trace_contention_end() on trie->lock and
leads to a dead-lock, so will fix the syzbot report by 2).

Ouch; sorry about this.
I reckon we should spell out the reason for this a bit more; would you
be happy with the commit message below?
| When CONFIG_DEBUG_BUGVERBOSE=n, we fail to add necessary padding bytes
| to bug_table entries, and as a result the last entry in a bug table will
| be ignored, potentially leading to an unexpected panic(). All prior
| entries in the table will be handled correctly.
|
| The arm64 ABI requires that struct fields of up to 8 bytes are
| naturally-aligned, with padding added within a struct such that struct
| are suitably aligned within arrays.
|
| When CONFIG_DEBUG_BUGVERPOSE=y, the layout of a bug_entry is:
|
| struct bug_entry {
| signed int bug_addr_disp; // 4 bytes
| signed int file_disp; // 4 bytes
| unsigned short line; // 2 bytes
| unsigned short flags; // 2 bytes
| }
|
| ... with 12 bytes total, requiring 4-byte alignment.
|
| When CONFIG_DEBUG_BUGVERBOSE=n, the layout of a bug_entry is:
|
| struct bug_entry {
| signed int bug_addr_disp; // 4 bytes
| unsigned short flags; // 2 bytes
| < implicit padding > // 2 bytes
| }
|
| ... with 8 bytes total, with 6 bytes of data and 2 bytes of trailing
| padding, requiring 4-byte alginment.
|
| When we create a bug_entry in assembly, we align the start of the entry
| to 4 bytes, which implicitly handles padding for any prior entries.
| However, we do not align the end of the entry, and so when
| CONFIG_DEBUG_BUGVERBOSE=n, the final entry lacks the trailing padding
| bytes.
|
| For the main kernel image this is not a problem as find_bug() doesn't
| depend on the trailing padding bytes when searching for entries:
|
| for (bug = __start___bug_table; bug < __stop___bug_table; ++bug)
| if (bugaddr == bug_addr(bug))
| return bug;
|
| However for modules, module_bug_finalize() depends on the trailing
| bytes when calculating the number of entries:
|
| mod->num_bugs = sechdrs[i].sh_size / sizeof(struct bug_entry);
|
| ... and as the last bug_entry lacks the necessary padding bytes, this entry
| will not be counted, e.g. in the case of a single entry:
|
| sechdrs[i].sh_size == 6
| sizeof(struct bug_entry) == 8;
|
| sechdrs[i].sh_size / sizeof(struct bug_entry) == 0;
|
| Consequently module_find_bug() will miss the last bug_entry when it does:
|
| for (i = 0; i < mod->num_bugs; ++i, ++bug)
| if (bugaddr == bug_addr(bug))
| goto out;
|
| ... which can lead to a kenrel panic due to an unhandled bug.
|
| This can be demonstrated with the following module:
|
| static int __init buginit(void)
| {
| WARN(1, "hello\n");
| return 0;
| }
|
| static void __exit bugexit(void)
| {
| }
|
| module_init(buginit);
| module_exit(bugexit);
| MODULE_LICENSE("GPL");
|
| ... which will trigger a kernel panic when loaded:

Cheers Jerry, that's reassuring. I'll write up a proper patch shortly -
with Monday morning eyes I realise this isn't entirely the right fix for
how I messed up here - and hope that my guess was right and it's the
source of Jon's issues as well. From experience I know that the effects
of the IOVA allocator going wrong can be varied and downright weird...
Thanks,
Robin.

That's not a valid tag here. Every bug we find - like hundreds of my

It's a cleanup not a bug fixing, so I think Fixes: tag is unnecessary.

My tests deliberately created/destroyed the mm for each test; surely we
don't want to inherit an MM in some arbitrary state? ... or is this just
so the mm can be allocated lazily upon the first mmap() within a test?

Why do we need this VMA given you have kunit_vm_mmap()?
This existed in my uaccess tests because I didn't use vm_mmap(), and I
wanted complete control over the addresses used.
Given you add kunit_vm_mmap(), I don't think we want this VMA -- it
doesn't serve any real purpose to tests, and accesses can erroneously
hit it, which is problematic.
UBUF_ADDR_BASE shouldn't be necessary either with kunit_vm_mmap(),
unless you want to use fixed addresses. That was just arbitrarily chosen
to be above NULL and the usual minimum mmap limit.

I2C core removes an argument from the i2c_mux_add_adapter() call to
further deprecate class based I2C device instantiation. All users are
converted, too. Other that that, Andi collected a number if I2C host
driver patches. Those merges have their own description.

How this is done? since the following xarray_erase() following the first
xarray_erase() will fail as the xarray slot referred by the same id has
already been erased?

Okay I understand. But this is indeed quite confusing. I see no cost of
also converting to cachefiles_req_put(req).

We will hold xa_lock while erasing the id to avoid concurrency.

The ondemand_read tends to confuse whether it's
ondemand_daemon_read or ondemand_data_read. I think it's better
to emphasise the read request, and currently only the ondemand
mode has a cachefiles req.

The definition of "vulnerability" from CVE.org is:
An instance of one or more weaknesses in a Product that can be
exploited, causing a negative impact to confidentiality, integrity, or
availability; a set of conditions or behaviors that allows the
violation of an explicit or implicit security policy.
Having a system that does not boot is a "negative impact to
availability", which is why this was selected for a CVE. I.e. if a new
kernel update has this problem in it, it would not allow the system to
boot correctly.
But, if the maintainer of the subsystem thinks this should not be
assigned a CVE because of this fix, we'll be glad to revoke it.
Michael, still want this revoked?

I think we might better to avoid unnecessary dependencies
since it relies on some "AI" magic and often mis-backportes
real dependencies.
I tend to leave real bugfixes first, and do cleanup next.
But please don't leave cleanup patches with "Fixes:" tags
anyway since it just misleads people.

The idea here is that because the wait only holds one reference count,
complete(&req->done) can only be called when the req has been
successfully removed from the xarry, otherwise the following UAF may
occur:
daemon_thread1 | daemon_thread2
-------------------------------------------
cachefiles_ondemand_daemon_read
xa_lock(&cache->reqs)
// select req_A
xa_unlock(&cache->reqs)
// restore req_A and read again
cachefiles_ondemand_daemon_read
xa_lock(&cache->reqs)
// select req_A
xa_unlock(&cache->reqs)
// goto error, erase success
xa_erase(&cache->reqs, id)
complete(&req_A->done)
// free req_A
// goto error, erase failed
complete(&req_A->done)
// req_A use-after-free
This is also why error requests and CLOSE requests are handled
together and why xas_load(&xas) == req is checked.

As mentioned above, the req may have been deleted or even the id

I don't think that's necessary, stable automatically backports the
relevant dependency patches in case of backport patch conflicts,
and later patches modify the logic here as well.
Or add Fixes tag for patch 2?

When "goto out;" is called in cachefiles_ondemand_send_req(),
it means that the req is unallocated/failed to be allocated/failed to
be inserted into the xarry, and therefore the req can only be accessed
by the current function, so there is no need to consider concurrency
and reference counting.
Thanks!

As Greg says, with PPC64_BIG_ENDIAN_ELF_ABI_V2 enabled the system won't
boot, so there is no chance of a vulnerability.

* [PATCH v4 3/3] perf annotate: LLVM-based disassembler
@ 2024-05-20 8:30 3% ` Steinar H. Gunderson
0 siblings, 0 replies; 200+ results
From: Steinar H. Gunderson @ 2024-05-20 8:30 UTC (permalink / raw)
To: acme; +Cc: linux-perf-users, linux-kernel, irogers, Steinar H. Gunderson
Support using LLVM as a disassembler method, allowing helperless
annotation in non-distro builds. (It is also much faster than
using libbfd or bfd objdump on binaries with a lot of debug
information.)
This is nearly identical to the output of llvm-objdump; there are
some very rare whitespace differences, some minor changes to demangling
(since we use perf's regular demangling and not LLVM's own) and
the occasional case where llvm-objdump makes a different choice
when multiple symbols share the same address. It should work across
all of LLVM's supported architectures, although I've only tested 64-bit
x86, and finding the right triple from perf's idea of machine
architecture can sometimes be a bit tricky. Ideally, we should have
some way of finding the triplet just from the file itself.

* [PATCH v3 3/3] perf annotate: LLVM-based disassembler
@ 2024-05-20 8:24 3% ` Steinar H. Gunderson
0 siblings, 0 replies; 200+ results
From: Steinar H. Gunderson @ 2024-05-20 8:24 UTC (permalink / raw)
To: acme; +Cc: linux-perf-users, linux-kernel, irogers, Steinar H. Gunderson
Support using LLVM as a disassembler method, allowing helperless
annotation in non-distro builds. (It is also much faster than
using libbfd or bfd objdump on binaries with a lot of debug
information.)
This is nearly identical to the output of llvm-objdump; there are
some very rare whitespace differences, some minor changes to demangling
(since we use perf's regular demangling and not LLVM's own) and
the occasional case where llvm-objdump makes a different choice
when multiple symbols share the same address. It should work across
all of LLVM's supported architectures, although I've only tested 64-bit
x86, and finding the right triple from perf's idea of machine
architecture can sometimes be a bit tricky. Ideally, we should have
some way of finding the triplet just from the file itself.

This requires a little more work actually. The CCS driver should probably
have the lens and flash bound to its pixel array rather than the source
(binner or scaler) sub-device.
I'll post a patch to add a warning for non-subdev use of this now, the rest
will need to wait a little.

Sorry the above description makes me confused. As the same request may
be got by different daemon threads multiple times, the introduced
refcount mechanism can't protect it from being completed multiple times
(which is expected). The refcount only protects it from being freed
multiple times.

This is actually a combination of a fix and a cleanup which combines the
logic of removing error request and the CLOSE requests into one place.
Also it relies on the cleanup made in patch 2 ("cachefiles: remove
err_put_fd tag in cachefiles_ondemand_daemon_read()"), making it
difficult to be atomatically back ported to the stable (as patch 2 is
not marked as "Fixes").
Thus could we make the fix first, and then make the cleanup.

Don't we need to also convert "kfree(req)" to cachefiles_req_put(req)
for the error path of cachefiles_ondemand_send_req()?
```
out:
/* Reset the object to close state in error handling path.

Hi Miroslav
First, in most cases, testing process is should be automated, which make using existing tracing infrastructure inconvenient. Second, livepatch is already use ftrace for functional replacement, I don’t think it is a good choice of using kernel tracing tool to trace a patched function.
At last, this attribute can be thought of as a state of a livepatch function. It is a state, like the "patched" "transition" state of a klp_patch. Adding this state will not break the state consistency of livepatch.

Wardenjohn

IMHO this doesn't warrant a CVE. The crash mentioned above happens at
boot, so the system is not vulnerable it's just broken :)

This is not a "bug", but a discrepancy; the following comment
by the author says "Start with the initial condition of 0 huge
pages", I am just ensuring that that is actually done. Although,
I am not sure about the utility of doing this in the first place,
since we are anyways trying to increase hugepages after that.
In the second patch, I have moved away this entire logic of
setting nr_hugepages to zero, to the place before we start
filling up memory; if you feel that this patch is unnecessary,
we may squash it.

FYI, we tested this patch on a Sapphire Rapids machine in our test
infrastructure. There are both improvements and regressions across
different benchmarks, which does show that the impact may be very
workload-dependent.

Over the course of my career, I've found the kind of workflow and level
of review you seem to asking for to be at best not useful, and at worst
harmful to productive functioning of a team - to my ability to teach
people and get them happy and productive.
The reality has just been that no one has ever been able to keep up with
the rate at which I work and write code [0], and attempting to do code
review of every patch means no one else gets anything done and we get
sidetracked on irrelevant details. When I do post my patches to the
list, the majority of what I get ends up being spelling fixes or at best
the kinds of bugs that shake out quickly in real testing. In short, I've
had to learn to write code without anyone looking over my shoulder, and
I take pride in debugging my own code and not saddling other people with
that.
So instead, I prioritize:
- real discussion over the work being done, which does tend to happen
person to person or in meetings (getting more of that on the list
would not be a bad idea; I do need to be spending more time writing
documentation and design docs, especially at this point).
- good effective test infrastructure
- heavy and thoughtful use of assertions; there's a real art to
effective use of assertions, where you think about what the
correctness proof would look like and write assertions for the
invariants (and assertions should be on _state_, not _logic_)
I also do (try to) post patches to the list that are doing something
interesting and worth discussion; the vast majority this cycle has been
boring syzbot crap...
IOW, I'm not trying to _flout_ process here, even if I do things
somewhat differently; I've got quite a few people I'm actively teaching
and bringing in and that's where most of my energy is going. And we do
spend a lot of time going over code together, the meetings I run
(especially with the younger guys) are very much code-and-workflow
focused.
You'll also find I'm quite responsive, on IRC and the list, should you
have anything you wish to complain or yell about.
(btw, there's also been some discussions in fs land about other people
changing their workflows to something that looks more like mine; get the
important stuff on the list, make the list less spammy, work with each
other on a quicker timeline than that. They're not quite doing what I'm
doing, but I do think there's room for the /way/ we do code review and
the expectations around it to evolve a bit. Personally, I mostly just
want code to be readable).
I personally approach code review as being primarily about mentorship...
I don't want people to have the expectation that I'm going to pore over
their code and find their bugs; I'm not going to do that. I expect
people to be adults, and take as much time as they need to to get it
right; if there's something they're not sure about, I expect _them_ to
bring it up. I personally feel that this mindset teaches more
responsibility and the "right" kind of defensiveness that it takes to
write reliable code.

So that particular code is used in debugfs (root only) or in dumps when
we're panicing; the reason it's %px and not hashed is because I not
uncommonly do things like grab addresses from the introspection and then
use kgdb for further inspection.
Does that alleviate your concern, if it's only exposed that way?
If not, perhaps some sort of config option is appropriate.
[0]: except Linus, who quite frequently leaves my jaw hanging with how
quickly he can read code and spot real issues.

* linux-next: Tree for May 20

Hi all,
Do not add any work intended for v6.11 to your linux-next included
branches until after v6.10-rc1 has been released.
Changes since 20240517:
The tip tree gained a conflict against the kbuild tree.
The refactor-heap tree still had its conflicts against the block tree
for which I dropped the refactor-heap tree.
Non-merge commits (relative to Linus' tree): 3211
3362 files changed, 433429 insertions(+), 58866 deletions(-)
----------------------------------------------------------------------------
I have created today's linux-next tree at
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
(patches at http://www.kernel.org/pub/linux/kernel/next/ ). If you
are tracking the linux-next tree using git, you should not use "git pull"
to do so as that will try to merge the new linux-next release with the
old one. You should use "git fetch" and checkout or reset to the new
master.
You can see which trees have been included by looking in the Next/Trees
file in the source. There is also the merge.log file in the Next
directory. Between each merge, the tree was built with a ppc64_defconfig
for powerpc, an allmodconfig for x86_64, a multi_v7_defconfig for arm
and a native build of tools/perf. After the final fixups (if any), I do
an x86_64 modules_install followed by builds for x86_64 allnoconfig,
powerpc allnoconfig (32 and 64 bit), ppc44x_defconfig, allyesconfig
and pseries_le_defconfig and i386, arm64, s390, sparc and sparc64
defconfig and htmldocs. And finally, a simple boot test of the powerpc
pseries_le_defconfig kernel in qemu (with and without kvm enabled).
Below is a summary of the state of the merge.
I am currently merging 373 trees (counting Linus' and 103 trees of bug
fix patches pending for the current merge release).
Stats about the size of the tree over time can be seen at
http://neuling.org/linux-next-size.html .
Status of my local build tests will be at
http://kisskb.ellerman.id.au/linux-next . If maintainers want to give
advice about cross compilers/configs that work, we are always open to add
more builds.
Thanks to Randy Dunlap for doing many randconfig builds. And to Paul
Gortmaker for triage and bug fixes.

Cheers,
Stephen Rothwell

I haven't got the root cause either.
From the log and code reading, it's using kexec_load to load kernel
for kexec rebooting. And the loading is being done when 2G memory is
being exhausted. Currently, the kexec_load will load memory at the top
of system RAM, near 2G. The left free memory should scatter in all
over the system RAM. While, seems the allocated page via
kimage_alloc_pages() are mostly destination pages, or the
kimage_is_destination_range() function incorrectly, then the while loop
will last very long and cost many pages, then causing the deadlock.
I will read code again when I am in very clear headed state.

* [RESEND PATCH v10 09/12] mm: implement LUF(Lazy Unmap Flush) defering tlb flush when folios get unmapped
2024-05-20 2:17 1% [RESEND PATCH v10 00/12] LUF(Lazy Unmap Flush) reducing tlb numbers over 90% Byungchul Park

A new mechanism, LUF(Lazy Unmap Flush), defers tlb flush until folios
that have been unmapped and freed, eventually get allocated again. It's
safe for folios that had been mapped read-only and were unmapped, since
the contents of the folios don't change while staying in pcp or buddy
so we can still read the data through the stale tlb entries.
tlb flush can be defered when folios get unmapped as long as it
guarantees to perform tlb flush needed, before the folios actually
become used, of course, only if all the corresponding ptes don't have
write permission. Otherwise, the system will get messed up.
To achieve that:
1. For the folios that map only to non-writable tlb entries, prevent
tlb flush during unmapping but perform it just before the folios
actually become used, out of buddy or pcp.
2. When any non-writable ptes change to writable e.g. through fault
handler, give up luf mechanism and perform tlb flush required
right away.
3. When a writable mapping is created e.g. through mmap(), give up
luf mechanism and perform tlb flush required right away.
No matter what type of workload is used for performance evaluation, the
result would be positive thanks to the unconditional reduction of tlb
flushes, tlb misses and interrupts. For the test, I picked up one of
the most popular and heavy workload, llama.cpp that is a
LLM(Large Language Model) inference engine.
The result would depend on memory latency and how often reclaim runs,
which implies tlb miss overhead and how many times unmapping happens.
In my system, the result shows:
1. tlb flushes are reduced about 95%.
2. tlb misses(itlb) are reduced about 80%.
3. tlb misses(dtlb store) are reduced about 57%.
4. tlb misses(dtlb load) are reduced about 24%.
5. tlb shootdown interrupts are reduced about 95%.
6. The test program runtime is reduced about 5%.
The test environment and the result is like:
Machine: bare metal, x86_64, Intel(R) Xeon(R) Gold 6430
CPU: 1 socket 64 core with hyper thread on
Numa: 2 nodes (64 CPUs DRAM 42GB, no CPUs CXL expander 98GB)
Config: swap off, numa balancing tiering on, demotion enabled
The test set:
llama.cpp/main -m $(70G_model1) -p "who are you?" -s 1 -t 15 -n 20 &
llama.cpp/main -m $(70G_model2) -p "who are you?" -s 1 -t 15 -n 20 &
llama.cpp/main -m $(70G_model3) -p "who are you?" -s 1 -t 15 -n 20 &
wait
where -t: nr of threads, -s: seed used to make the runtime stable,
-n: nr of tokens that determines the runtime, -p: prompt to ask,
-m: LLM model to use.
Run the test set 10 times successively with caches dropped every run
via 'echo 3 > /proc/sys/vm/drop_caches'. Each inference prints its
runtime at the end of each.

Hi everyone,
While I'm working with a tiered memory system e.g. CXL memory, I have
been facing migration overhead esp. tlb shootdown on promotion or
demotion between different tiers. Yeah.. most tlb shootdowns on
migration through hinting fault can be avoided thanks to Huang Ying's
work, commit 4d4b6d66db ("mm,unmap: avoid flushing tlb in batch if PTE
is inaccessible"). See the following link for more information:
https://lore.kernel.org/lkml/20231115025755.GA29979@system.software.com/
However, it's only for migration through hinting fault. I thought it'd
be much better if we have a general mechanism to reduce all the tlb
numbers that we can apply to any unmap code, that we normally believe
tlb flush should be followed.
I'm suggesting a new mechanism, LUF(Lazy Unmap Flush), defers tlb flush
until folios that have been unmapped and freed, eventually get allocated
again. It's safe for folios that had been mapped read-only and were
unmapped, since the contents of the folios don't change while staying in
pcp or buddy so we can still read the data through the stale tlb entries.
tlb flush can be defered when folios get unmapped as long as it
guarantees to perform tlb flush needed, before the folios actually
become used, of course, only if all the corresponding ptes don't have
write permission. Otherwise, the system will get messed up.
To achieve that:
1. For the folios that map only to non-writable tlb entries, prevent
tlb flush during unmapping but perform it just before the folios
actually become used, out of buddy or pcp.
2. When any non-writable ptes change to writable e.g. through fault
handler, give up luf mechanism and perform tlb flush required
right away.
3. When a writable mapping is created e.g. through mmap(), give up
luf mechanism and perform tlb flush required right away.
No matter what type of workload is used for performance evaluation, the
result would be positive thanks to the unconditional reduction of tlb
flushes, tlb misses and interrupts. For the test, I picked up one of
the most popular and heavy workload, llama.cpp that is a
LLM(Large Language Model) inference engine.
The result would depend on memory latency and how often reclaim runs,
which implies tlb miss overhead and how many times unmapping happens.
In my system, the result shows:
1. tlb flushes are reduced about 95%.
2. tlb misses(itlb) are reduced about 80%.
3. tlb misses(dtlb store) are reduced about 57%.
4. tlb misses(dtlb load) are reduced about 24%.
5. tlb shootdown interrupts are reduced about 95%.
6. The test program runtime is reduced about 5%.
The test environment and the result is like:
Machine: bare metal, x86_64, Intel(R) Xeon(R) Gold 6430
CPU: 1 socket 64 core with hyper thread on
Numa: 2 nodes (64 CPUs DRAM 42GB, no CPUs CXL expander 98GB)
Config: swap off, numa balancing tiering on, demotion enabled
The test set:
llama.cpp/main -m $(70G_model1) -p "who are you?" -s 1 -t 15 -n 20 &
llama.cpp/main -m $(70G_model2) -p "who are you?" -s 1 -t 15 -n 20 &
llama.cpp/main -m $(70G_model3) -p "who are you?" -s 1 -t 15 -n 20 &
wait
where -t: nr of threads, -s: seed used to make the runtime stable,
-n: nr of tokens that determines the runtime, -p: prompt to ask,
-m: LLM model to use.
Run the test set 10 times successively with caches dropped every run
via 'echo 3 > /proc/sys/vm/drop_caches'. Each inference prints its
runtime at the end of each.

Changes from v9:
1. Expand the candidate to apply this mechanism:
BEFORE - The souce folios at any type of migration.
AFTER - Any folios that have been unmapped and freed.
2. Change the workload for test:
BEFORE - XSBench
AFTER - llama.cpp (one of the most popluar real workload)
3. Change the test environment:
BEFORE - qemu machine, too small DRAM(1GB), large remote mem
AFTER - bare metal, real CXL memory, practical memory size
4. Rename the mechanism from MIGRC(Migration Read Copy) to
LUF(Lazy Unmap Flush) to reflect the current version of the
mechanism can be applied not only to unmap during migration
but any unmap code e.g. unmap in shrink_folio_list().
5. Fix build error for riscv. (feedbacked by kernel test bot)
6. Supplement commit messages to describe what this mechanism is
for, especially in the patches for arch code. (feedbacked by
Thomas Gleixner)
7. Clean up some trivial things.
Changes from v8:
1. Rebase on akpm/mm.git mm-unstable as of April 18, 2024.
2. Supplement comments and commit message.
3. Change the candidate to apply migrc mechanism:
BEFORE - The source folios at demotion and promotion.
AFTER - The souce folios at any type of migration.
4. Change how migrc mechanism works:
BEFORE - Reduce tlb flushes by deferring folio_free() for
source folios during demotion and promotion.
AFTER - Reduce tlb flushes by deferring tlb flush until they
actually become used, out of pcp or buddy. The
current version of migrc does *not* defer calling
folio_free() but let it go as it is as the same as
vanilla kernel, with the folios marked kind of 'need
to tlb flush'. And then handle the flush when the
page exits from pcp or buddy so as to prevent
changing vm stats e.g. free pages.
Changes from v7:
1. Rewrite cover letter to explain what 'migrc' mechasism is.
(feedbacked by Andrew Morton)
2. Supplement the commit message of a patch 'mm: Add APIs to
free a folio directly to the buddy bypassing pcp'.
(feedbacked by Andrew Morton)
Changes from v6:
1. Fix build errors in case of
CONFIG_ARCH_WANT_BATCHED_UNMAP_tlb_FLUSH disabled by moving
migrc_flush_{start,end}() calls from arch code to
try_to_unmap_flush() in mm/rmap.c.
Changes from v5:
1. Fix build errors in case of CONFIG_MIGRATION disabled or
CONFIG_HWPOISON_INJECT moduled. (feedbacked by kernel test
bot and Raymond Jay Golo)
2. Organize migrc code with two kconfigs, CONFIG_MIGRATION and
CONFIG_ARCH_WANT_BATCHED_UNMAP_tlb_FLUSH.
Changes from v4:
1. Rebase on v6.7.
2. Fix build errors in arm64 that is doing nothing for tlb flush
but has CONFIG_ARCH_WANT_BATCHED_UNMAP_tlb_FLUSH. (reported
by kernel test robot)
3. Don't use any page flag. So the system would give up migrc
mechanism more often but it's okay. The final improvement is
good enough.
4. Instead, optimize full tlb flush(arch_tlbbatch_flush()) by
avoiding redundant CPUs from tlb flush.
Changes from v3:
1. Don't use the kconfig, CONFIG_MIGRC, and remove sysctl knob,
migrc_enable. (feedbacked by Nadav)
2. Remove the optimization skipping CPUs that have already
performed tlb flushes needed by any reason when performing
tlb flushes by migrc because I can't tell the performance
difference between w/ the optimization and w/o that.
(feedbacked by Nadav)
3. Minimize arch-specific code. While at it, move all the migrc
declarations and inline functions from include/linux/mm.h to
mm/internal.h (feedbacked by Dave Hansen, Nadav)
4. Separate a part making migrc paused when the system is in
high memory pressure to another patch. (feedbacked by Nadav)
5. Rename:
a. arch_tlbbatch_clean() to arch_tlbbatch_clear(),
b. tlb_ubc_nowr to tlb_ubc_ro,
c. migrc_try_flush_free_folios() to migrc_flush_free_folios(),
d. migrc_stop to migrc_pause.
(feedbacked by Nadav)
6. Use ->lru list_head instead of introducing a new llist_head.
(feedbacked by Nadav)
7. Use non-atomic operations of page-flag when it's safe.
(feedbacked by Nadav)
8. Use stack instead of keeping a pointer of 'struct migrc_req'
in struct task, which is for manipulating it locally.
(feedbacked by Nadav)
9. Replace a lot of simple functions to inline functions placed
in a header, mm/internal.h. (feedbacked by Nadav)
10. Add additional sufficient comments. (feedbacked by Nadav)
11. Remove a lot of wrapper functions. (feedbacked by Nadav)
Changes from RFC v2:
1. Remove additional occupation in struct page. To do that,
unioned with lru field for migrc's list and added a page
flag. I know page flag is a thing that we don't like to add
but no choice because migrc should distinguish folios under
migrc's control from others. Instead, I force migrc to be
used only on 64 bit system to mitigate you guys from getting
angry.
2. Remove meaningless internal object allocator that I
introduced to minimize impact onto the system. However, a ton
of tests showed there was no difference.
3. Stop migrc from working when the system is in high memory
pressure like about to perform direct reclaim. At the
condition where the swap mechanism is heavily used, I found
the system suffered from regression without this control.
4. Exclude folios that pte_dirty() == true from migrc's interest
so that migrc can work simpler.
5. Combine several patches that work tightly coupled to one.
6. Add sufficient comments for better review.
7. Manage migrc's request in per-node manner (from globally).
8. Add tlb miss improvement in commit message.
9. Test with more CPUs(4 -> 16) to see bigger improvement.
Changes from RFC:
1. Fix a bug triggered when a destination folio at the previous
migration becomes a source folio at the next migration,
before the folio gets handled properly so that the folio can
play with another migration. There was inconsistency in the
folio's state. Fixed it.
2. Split the patch set into more pieces so that the folks can
review better. (Feedbacked by Nadav Amit)
3. Fix a wrong usage of barrier e.g. smp_mb__after_atomic().
(Feedbacked by Nadav Amit)
4. Tried to add sufficient comments to explain the patch set
better. (Feedbacked by Nadav Amit)

I think the root cause is that PG_reserved is inhibited on compound pages. So my original version of patch breaks the assumption.
But since PG_reserved is to be removed, I have dropped this patch.
Thanks.

* [PATCH] f2fs: fix to truncate preallocated blocks in f2fs_file_open()

It is because inode.i_crypt_info is not initialized during below path:
- mount
- f2fs_fill_super
- f2fs_disable_checkpoint
- f2fs_gc
- f2fs_iget
- f2fs_truncate
So, let's relocate truncation of preallocated blocks to f2fs_file_open(),
after fscrypt_file_open().
Fixes: d4dd19ec1ea0 ("f2fs: do not expose unwritten blocks to user by DIO")

Livepatch module usually used to modify kernel functions.
If the patched function have bug, it may cause serious result
such as kernel crash.
This is a kobject attribute of klp_func. Sysfs interface named
"called" is introduced to livepatch which will be set as true
if the patched function is called.
/sys/kernel/livepatch/<patch>/<object>/<function,sympos>/called
This value "called" is quite necessary for kernel stability
assurance for livepatching module of a running system.
Testing process is important before a livepatch module apply to
a production system. With this interface, testing process can
easily find out which function is successfully called.
Any testing process can make sure they have successfully cover
all the patched function that changed with the help of this interface.

When asn1_encode_sequence() fails, WARN is not the correct solution.
1. asn1_encode_sequence() is not an internal function (located
in lib/asn1_encode.c).
2. Location is known, which makes the stack trace useless.
3. Results a crash if panic_on_warn is set.
It is also noteworthy that the use of WARN is undocumented, and it
should be avoided unless there is a carefully considered rationale to
use it.
Replace WARN with pr_err, and print the return value instead, which is
only useful piece of information.

The MCQ_OPR_OFFSET_n macro has taken 'hba' on the caller context
without receiving 'hba' instance as an argument. To prevent potential
bugs in future use cases, this patch added an argument 'hba'.

Hello,
This patch set fixes an potential bug for further usages in ufs-mcq.c and
contains a simple clean-up converting macro to an inline function.
Please review.
Thanks,
v2:
- Fix missing argument 'hba' in MCQ_OPR_OFFSET_n by converting it to an
inline function (Bart)
- Added [2/2] patch to convert the remaining one macro in ufs-mcq.c to an
inline function along with the previous patch for the sake of consistency.

For tests that need to allocate using vm_mmap() (e.g. usercopy and
execve), provide the interface to have the allocation tracked by KUnit
itself. This requires bringing up a placeholder userspace mm.
This combines my earlier attempt at this with Mark Rutland's version[1].

bcachefs: add no_invalid_checks flag (2024-05-09 16:24:30 -0400)
----------------------------------------------------------------
bcachefs changes for 6.10-rc1
- More safety fixes, primarily found by syzbot
- Run the upgrade/downgrade paths in nochnages mode. Nochanges mode is
primarily for testing fsck/recovery in dry run mode, so it shouldn't
change anything besides disabling writes and holding dirty metadata in
memory.
The idea here was to reduce the amount of activity if we can't write
anything out, so that bringing up a filesystem in "super ro" mode
would be more lilkely to work for data recovery - but norecovery is
the correct option for this.
- btree_trans->locked; we now track whether a btree_trans has any btree
nodes locked, and this is used for improved assertions related to
trans_unlock() and trans_relock(). We'll also be using it for
improving how we work with lockdep in the future: we don't want
lockdep to be tracking individual btree node locks because we take too
many for lockdep to track, and it's not necessary since we have a
cycle detector.
- Trigger improvements that are prep work for online fsck
- BTREE_TRIGGER_check_repair; this regularizes how we do some repair
work for extents that goes with running triggers in fsck, and fixes
some subtle issues with transaction restarts there.
- bch2_snapshot_equiv() has now been ripped out of fsck.c; snapshot
equivalence classes are for when snapshot deletion leaves behind
redundant snapshot nodes, but snapshot deletion now cleans this up
right away, so the abstraction doesn't need to leak.
- Improvements to how we resume writing to the journal in recovery. The
code for picking the new place to write when reading the journal is
greatly simplified and we also store the position in the superblock
for when we don't read the journal; this means that we preserve more
of the journal for list_journal debugging.
- Improvements to sysfs btree_cache and btree_node_cache, for debugging
memory reclaim.
- We now detect when we've blocked for 10 seconds on the allocator in
the write path and dump some useful info.
- Safety fixes for devices references: this is a big series that changes
almost all device lookups to properly check if the device exists and
take a reference to it.
Previously we assumed that if a bkey exists that references a device
then the device must exist, and this was enforced in .invalid methods,
but this was incorrect because it meant device removal relied on
accounting being correct to not leave keys pointing to invalid
devices, and that's not something we can assume.
Getting the "pointer to invalid device" checks out of our .invalid()
methods fixes some long standing device removal bugs; the only
outstanding bug with device removal now is a race between the discard
path and deleting alloc info, which should be easily fixed.
- The allocator now prefers not to expand the new
member_info.btree_allocated bitmap, meaning if repair ever requires
scanning for btree nodes (because of a corrupt interior nodes) we
won't have to scan the whole device(s).
- New coding style document, which among other things talks about the
correct usage of assertions

Hi all,
I have the exact same bug. I'm using the NixOS kernel but as soon as it
was updated to 6.8.10 my server has gone in a crash-reboot-loop.
The server is hosting an NFS deamon and it crashes about 10 seconds
after the tty login prompt is displayed.
Dowgrading to 6.8.9 fixes the issue.

* [PATCH net v5] nfc: nci: Fix uninit-value in nci_rx_work

syzbot reported the following uninit-value access issue [1]
nci_rx_work() parses received packet from ndev->rx_q. It should be
validated header size, payload size and total packet size before
processing the packet. If an invalid packet is detected, it should be
silently discarded.
Fixes: d24b03535e5e ("nfc: nci: Fix uninit-value in nci_dev_up and nci_ntf_packet")
Reported-and-tested-by: syzbot+d7b4dc6cd50410152534@syzkaller.appspotmail.com
Closes: https://syzkaller.appspot.com/bug?extid=d7b4dc6cd50410152534 [1]
Signed-off-by: Ryosuke Yasuoka <ryasuoka@redhat.com>

v5
- As Jakub pointed out, add BUILD_BUG_ON() and make the patch simpler.
All validating packet size has been done in nci_valid_size() before
switch statement.
- Also, v4 patch changed break to continue when the invalid packet is
detected. Since it is unrelated to this patch, leave it in this patch.
This fix was proposed in another patch.
v4
- v3 patch uses goto statement and it makes codes complicated. So this
patch simply calls kfree_skb inside loop and remove goto statement.
- [2] inserted kcov_remote_stop() to fix kcov check. However, as we
discuss about my v3 patch [3], it should not exit the for statement
and should continue processing subsequent packets. This patch removes
them and simply insert continue statement.
[2] https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=19e35f24750d
v3
https://lore.kernel.org/netdev/20240502082323.250739-1-ryasuoka@redhat.com/T/
- As Simon pointed out, the valid packets will reach invalid_pkt_free
and kfree_skb(skb) after being handled correctly in switch statement.
It can lead to double free issues, which is not intended. So this patch
uses "continue" instead of "break" in switch statement.
- In the current implementation, once zero payload size is detected, the
for statement exits. It should continue processing subsequent packets.
So this patch just frees skb in invalid_pkt_free when the invalid
packets are detected. [3]

Many people/distros run the built-in unit tests at boot time, and having
crashes is not a good idea. So if you don't enable this option, great,
this CVE isn't relevent, but if you do, it's an in-kernel crash which is
not good, and this is the fix for that.
So I don't think this CVE should be rejected, sorry.

So, if there is an error, we just continue through? What about the code
that accesses the region afterwards?
If error handling becomes void, then there should be an early return
instead of dropping the error check completely.

You have dropped the iounmap(). However now the error path should
remain. The put_device() must be called. So fix the label name and just
drop the iounmap().

* [PATCH] livepatch: introduce klp_func called interface

Livepatch module usually used to modify kernel functions.
If the patched function have bug, it may cause serious result
such as kernel crash.
This commit introduce a read only interface of livepatch
sysfs interface. If a livepatch function is called, this
sysfs interface "called" of the patched function will
set to be 1.
/sys/kernel/livepatch/<patch>/<object>/<function,sympos>/called
This value "called" is quite necessary for kernel stability assurance for livepatching
module of a running system. Testing process is important before a livepatch module
apply to a production system. With this interface, testing process can easily
find out which function is successfully called. Any testing process can make sure they
have successfully cover all the patched function that changed with the help of this interface.

After further experimentation, I've come to the conclusion that this is
a bug in the pxa uart driver, and this patch simply exposed the bug.
I'll submit a patch to fix the issue in the pxa driver.
If anyone's interested in the details: basically, the pxa driver in its
current state doesn't work correctly if it receives a TX interrupt when
the circular buffer is empty. It handles it, but then gets stuck waiting
for the next TX IRQ that will never happen because no characters were
transmitted. The way stop_tx() was previously being called before the
transmitter was empty, it prevented that situation from happening
because toggling the TX interrupt enable flag off (with stop_tx) and
back on (with the next start_tx) causes a new TX interrupt to fire and
kickstarts the transmit process again.
The 8250 driver, for example, isn't affected by this problem because it
effectively does stop_tx() on its own if it detects an empty circular
buffer in the TX interrupt handler. Adding similar logic to the pxa
driver fixes it.
Doug

Serge E. Hallyn, open list:SECURITY SUBSYSTEM
When asn1_encode_sequence() fails, WARN is not the correct solution.
1. asn1_encode_sequence() is not an internal function (located
in lib/asn1_encode.c).
2. Location is known, which makes the stack trace useless.
3. Results a crash if panic_on_warn is set.
It is also noteworthy that the use of WARN is undocumented, and it
should be avoided unless there is a carefully considered rationale to
use it.
Replace WARN with pr_err, and print the return value instead, which is
only useful piece of information.

When asn1_encode_sequence() fails, WARN is not the correct solution.
1. asn1_encode_sequence() is not an internal function (located
in lib/asn1_encode.c).
2. Location is known, which makes the stack trace useless.
3. Results a crash if panic_on_warn is set.
It is also noteworthy that the use of WARN is undocumented, and it
should be avoided unless there is a carefully considered rationale to
use it.
Replace WARN with pr_err, and print the return value instead, which is
only useful piece of information.

appears to be causing this circular lock dependency.

With this in place I no longer see the mapping fail on the nvidia system.

* [PATCH v2 3/3] perf annotate: LLVM-based disassembler
@ 2024-05-18 16:53 3% ` Steinar H. Gunderson
0 siblings, 0 replies; 200+ results
From: Steinar H. Gunderson @ 2024-05-18 16:53 UTC (permalink / raw)
To: acme; +Cc: linux-perf-users, linux-kernel, irogers, Steinar H. Gunderson
Support using LLVM as a disassembler method, allowing helperless
annotation in non-distro builds. (It is also much faster than
using libbfd or bfd objdump on binaries with a lot of debug
information.)
This is nearly identical to the output of llvm-objdump; there are
some very rare whitespace differences, some minor changes to demangling
(since we use perf's regular demangling and not LLVM's own) and
the occasional case where llvm-objdump makes a different choice
when multiple symbols share the same address. It should work across
all of LLVM's supported architectures, although I've only tested 64-bit
x86, and finding the right triple from perf's idea of machine
architecture can sometimes be a bit tricky. Ideally, we should have
some way of finding the triplet just from the file itself.

The sysctl core is preparing to only expose instances of
struct ctl_table as "const".
This will also affect the ctl_table argument of sysctl handlers,
for which bpf_sysctl_kern::table is also used.
As the function prototype of all sysctl handlers throughout the tree
needs to stay consistent that change will be done in one commit.
To reduce the size of that final commit, switch this utility type which
is not bound by "typedef proc_handler" to "const struct ctl_table".
No functional change.

This patch(set) is meant to be applied through your subsystem tree.
Or at your preference through the sysctl tree.
Motivation
==========
Moving structures containing function pointers into unmodifiable .rodata
prevents attackers or bugs from corrupting and diverting those pointers.
Also the "struct ctl_table" exposed by the sysctl core were never meant
to be mutated by users.
For this goal changes to both the sysctl core and "const" qualifiers for
various sysctl APIs are necessary.
Full Process
============
* Drop ctl_table modifications from the sysctl core ([0], in mainline)
* Constify arguments to ctl_table_root::{set_ownership,permissions}
([1], in mainline)
* Migrate users of "ctl_table_header::ctl_table_arg" to "const".
(in mainline)
* Afterwards convert "ctl_table_header::ctl_table_arg" itself to const.
(in mainline)
* Prepare helpers used to implement proc_handlers throughout the tree to
use "const struct ctl_table *". ([2], in progress, this patch)
* Afterwards switch over all proc_handlers callbacks to use
"const struct ctl_table *" in one commit. ([2], in progress)
Only custom handlers will be affected, the big commit avoids a
disruptive and messy transition phase.
* Switch over the internals of the sysctl core to "const struct ctl_table *" (to be done)
* Switch include/linux/sysctl.h to "const struct ctl_table *" (to be done)
* Transition instances of "struct ctl_table" through the tree to const (to be done)

Calibrated data will be set to default after loading DSP config params,
which will cause speaker protection work abnormally. Reload calibrated
data after loading DSP config params. Remove declaration of unused API
which load calibrated data in wrong sequence, changed the copyright year
and correct file name in license
header.
Fixes: ef3bcde75d06 ("ASoc: tas2781: Add tas2781 driver")

v6:
- Merge into one patch
v5:
- correct changelog has no much relationship with the patch
v4:
- Use the the culprit of the bug itself as the fixes tag
- Better variant for tasdev_load_calibrated_data in order to much easier
to read and understand and maintain, as it makes harder to squeeze the
code.
- Fix the indentation and move operator to the previous line.
v3:
- No changes.
- Remove redundant return in tasdev_load_calibrated_data
- Put the second function parameter into the previous line for
tasdev_load_calibrated_data
v2:
- In the Subject, fixed --> Fix
- Add Fixes tag
- dsp --> DSP
- Changed the copyright year to 2024 in the related files
- In tas2781-dsp.h, __TASDEVICE_DSP_H__ --> __TAS2781_DSP_H__
v1:
- Download calibrated data after loading the new DSP config params
- Remove tasdevice_prmg_calibdata_load, because it is unnecessary to load
calibrated data after loading DSP program.
- call tasdevice_prmg_load instead of tasdevice_prmg_calibdata_load, it
is unnecessary to load calibrated data after loading DSP program. Load
it after loading DSP config params each time.

* [PATCH] mm/hugetlb: constify ctl_table arguments of utility functions

The sysctl core is preparing to only expose instances of
struct ctl_table as "const".
This will also affect the ctl_table argument of sysctl handlers.
As the function prototype of all sysctl handlers throughout the tree
needs to stay consistent that change will be done in one commit.
To reduce the size of that final commit, switch utility functions which
are not bound by "typedef proc_handler" to "const struct ctl_table".
No functional change.

This patch(set) is meant to be applied through your subsystem tree.
Or at your preference through the sysctl tree.
Motivation
==========
Moving structures containing function pointers into unmodifiable .rodata
prevents attackers or bugs from corrupting and diverting those pointers.
Also the "struct ctl_table" exposed by the sysctl core were never meant
to be mutated by users.
For this goal changes to both the sysctl core and "const" qualifiers for
various sysctl APIs are necessary.
Full Process
============
* Drop ctl_table modifications from the sysctl core ([0], in mainline)
* Constify arguments to ctl_table_root::{set_ownership,permissions}
([1], in mainline)
* Migrate users of "ctl_table_header::ctl_table_arg" to "const".
(in mainline)
* Afterwards convert "ctl_table_header::ctl_table_arg" itself to const.
(in mainline)
* Prepare helpers used to implement proc_handlers throughout the tree to
use "const struct ctl_table *". ([2], in progress, this patch)
* Afterwards switch over all proc_handlers callbacks to use
"const struct ctl_table *" in one commit. ([2], in progress)
Only custom handlers will be affected, the big commit avoids a
disruptive and messy transition phase.
* Switch over the internals of the sysctl core to "const struct ctl_table *" (to be done)
* Switch include/linux/sysctl.h to "const struct ctl_table *" (to be done)
* Transition instances of "struct ctl_table" through the tree to const (to be done)

I'm pretty sure that the 'undefined' behaviour of signed overflow
it so that cpu can do saturating arithmetic (useful on analogue data)
or can fault (and maybe generate a signal) and still be compliant.
The Linux kernel (and pretty much all userspace) doesn't want either
behaviour.
(Unexpected saturation leads to very confusing bugs that are as bad
as wrapping but much less obvious.)
I do wonder whether trying to remove all arithmetic on char/short
variables should be an aim.
The only reason to have char/short is to reduce the size of a structure.
A first stage would removing all short locals, function parameters
and function returns.
There will be some (sensible) false positives for char.
If you breath on a char/short it becomes 'signed int',
even (x ? 'a' : 'b') is 'signed int'.

xmit() functions should consume skb or return error codes in error
paths.
When the configuration "CONFIG_INET_ESPINTCP" is not set, the
implementation of the function "esp_output_tail_tcp" violates this rule.
The function frees the skb and returns the error code.
This change removes the kfree_skb from both functions, for both
esp4 and esp6.
WARN_ON is added because esp_output_tail_tcp() should never be called if
CONFIG_INET_ESPINTCP is not set.
This bug was discovered and resolved using Coverity Static Analysis
Security Testing (SAST) by Synopsys, Inc.

* [RFC PATCH v2 0/1] Introduce per-task io utilization boost

There is a feature inside of both schedutil and intel_pstate called
iowait boosting which tries to prevent selecting a low frequency
during IO workloads when it impacts throughput.
The feature is implemented by checking for task wakeups that have
the in_iowait flag set and boost the CPU of the rq accordingly
(implemented through cpufreq_update_util(rq, SCHED_CPUFREQ_IOWAIT)).
The necessity of the feature is argued with the potentially low
utilization of a task being frequently in_iowait (i.e. most of the
time not enqueued on any rq and cannot build up utilization).
The RFC focuses on the schedutil implementation.
intel_pstate implementation is possible, but with reviews of v1 it
seems a governor-based implementation is preferred.
Current schedutil iowait boosting has several issues:
1. Boosting happens even in scenarios where it doesn't improve
throughput. [1]
2. The boost is not accounted for in EAS: a) feec() will only consider
the actual task utilization for task placement, but another CPU might
be more energy-efficient at that capacity than the boosted one.)
b) When placing a non-IO task while a CPU is boosted compute_energy()
assumes a lower OPP than what is actually applied. This leads to
wrong EAS decisions.
3. Actual IO heavy workloads are hardly distinguished from infrequent
in_iowait wakeups.
4. The boost isn't associated with a task, it therefore isn't considered
for task placement, potentially missing out on higher capacity CPUs on
heterogeneous CPU topologies.
5. The boost isn't associated with a task, it therefore lingers on the
rq even after the responsible task has migrated / stopped.
6. The boost isn't associated with a task, it therefore needs to ramp
up again when migrated.
7. Since schedutil doesn't know which task is getting woken up,
multiple unrelated in_iowait tasks might lead to boosting.
8. Boosting is hard to control with UCLAMP_MAX.
We attempt to mitigate all of the above by reworking the way the
iowait boosting (io boosting from here on) works in two major ways:
- Carry the boost in task_struct, so it is a per-task attribute and
behaves similar to utilization of the task in some ways.
- Employ a counting-based tracking strategy that only boosts as long
as it sees benefits and returns to minimal boosting dynamically.
Note that some the issues (1, 3) can be solved by using a
counting-based strategy on a per-rq basis, i.e. in sugov entirely.
Experiments with Android in particular showed that such a strategy
(which necessarily needs longer intervals to be reasonably stable)
is too prone to migrations to be useful generally.
We therefore consider the additional complexity of such a per-task
based approach like proposed to be worth it.
We require a minimum of 1000 iowait wakeups per second to start
boosting.
This isn't too far off from what sugov currently does, since it resets
the boost if it hasn't seen an iowait wakeup for TICK_NSEC.
For CONFIG_HZ=1000 we are on par, for anything below we are stricter.
We justify this by the small possible improvement by boosting in the
first place with 'rare' iowait wakeups.
When IO even leads to a task being in iowait isn't as straightforward
to explain.
Of course if the issued IO can be served by the page cache (e.g. on
reads because the pages are contained, on writes because they can be
marked dirty and the writeback takes care of it later) the actual
issuing task is usually not in iowait.
We consider this the good case, since whenever the scheduler and a
potential userspace / kernel switch is in the critical path for IO
there is possibly overhead impacting throughput.
We therefore focus on random read from here on, because (on synchronous
IO [3]) this will lead to the task being set in iowait for every IO.
This is where iowait boosting shows its biggest throughput improvement.
From here on IOPS (IO operations per second, assume 4K size) and iowait
wakeups may therefore be used interchangeably.
Performance:
Throughput for random read tries to be on par with the sugov
implementation of iowait boosting for reasonably long-lived workloads.
See the following table for some results, values are in IOPS, the tests
are ran for 30s with pauses in-between, results are sorted.

Based on the above we can basically categorize these into the following
three:
a) boost is useful
b) boost irrelevant (util dominates)
c) boost is energy-inefficient (boost dominates)
The aim of the patch is to boost as much as necessary for a) while
boosting little for c) (thus saving energy).
Energy-savings:
Regarding sugov iowait boosting problem 1 mentioned earlier,
some improvement can be seen:
Tested on rk3399 (LLLL)(bb) with an NVMe, 30s runtime
CPU0 perf domain spans 0-3 with 400MHz to 1400MHz
CPU4 perf domain spans 4-5 with 400MHz to 1800MHz
iouring6x128:
Sugov iowait boost:
Average frequency for CPU0 : 1.180 GHz
Average frequency for CPU4 : 1.504 GHz
Per-task tracking:
Average frequency for CPU0 : 0.858 GHz
Average frequency for CPU4 : 1.271 GHz
iouring12x128:
Sugov iowait boost:
Average frequency for CPU0 : 1.324 GHz
Average frequency for CPU4 : 1.444 GHz
Per-task tracking:
Average frequency for CPU0 : 0.962 GHz
Average frequency for CPU4 : 1.155 GHz
(In both cases actually 400MHz on both perf domains is possible, more
fine-tuning could get us closer. [2])
[1]
There are many scenarios when it doesn't, so let's start with
explaining when it does:
Boosting improves throughput if there is frequent IO to a device from
one or few origins, such that the device is likely idle when the task
is enqueued on the rq and reducing this time cuts down on the device
idle time.
This might not be true (and boosting doesn't help) if:
- The device uses the idle time to actually commit the IO to
persistent storage or do other management activity (this can be
observed with e.g. writes to flash-based storage, which will usually
write to cache and flush the cache when idle or necessary).
- The device is under thermal pressure and needs idle time to cool off
(not uncommon for e.g. nvme devices).
Furthermore the assumption (the device being idle while task is
enqueued) is false altogether if:
- Other tasks use the same device.
- The task uses asynchronous IO with iodepth > 1 like io_uring, the
in_iowait is then just to fill the queue on the host again.
- The task just sets in_iowait to signal it is waiting on io to not
appear as system idle, it might not send any io at all (cf. with
the various occurrences of in_iowait, io_mutex_lock, io_schedule*
and wait_for_*io*).
[3]
Unfortunately even for asynchronous IO iowait may be set, in the case
of io_uring this is specifically for the iowait boost to trigger, see
commit ("8a796565cec3 io_uring: Use io_schedule* in cqring wait")
which is why the energy-savings are so significant here, as io_uring
load on the CPU is minimal.
Problems encountered:
- Higher cap is not always beneficial, we might place the task away
from the CPU where the interrupt handler is running, making it run
on an unboosted CPU which may have a bigger impact than the difference
between the CPU's capacity the task moved to. (Of course the boost will
then be reverted again, but a ping-pong every interval is possible).
- [2] tracking and scaling can be improved (io_uring12 still shows
boosting): Unfortunately tracking purely per-task shows some limits.
One task might show more iowaits per second when boosted, but overall
throughput doesn't increase => there is still some boost.
The task throughput improvement is somewhat limited though,
so by fine-tuning the thresholds there could be mitigations.
v1 discussion:
https://lore.kernel.org/lkml/20240304201625.100619-1-christian.loehle@arm.com/
Changes since v1:
- Rebase onto 6.9
- Range from reducing the level to increasing depends on the total number
of iowaits now. (io_boost_threshold())
- Fixed bug at io_boost_level reduce.
- Removed open-coding for task placement through uclamp_eff_value()
- Move most of the logic into sugov.
- Added a mechanism to maintain boost when boosted task is not on the rq.
v1 relied on rate_limit_us being high enough to maintain the boost.
Thereby also removing the rq max-aggregation and its atomic update.
This is implemented by the most recent io boost being held, which
works well enough in practice to not warrant anything like a rolling
window tracking of recent io boosts at the rq.
- Benchmark numbers all taken with direct and none as io scheduler to
address Bart's comments. Also removed most benchmarks for now as
discussion from v1 suggested to ignore single completion-queue systems,
as they are more and more becoming a thing of the past.
v1 reviews not (yet) addressed:
- Qais would prefer the logic to take affect during actual in_iowait flag
setting, instead of enqueue/dequeue, that is a bit awkward as of now, as
in_iowait is being set both through various wrappers and directly.
This might change though:
https://lore.kernel.org/lkml/20240416121526.67022-1-axboe@kernel.dk/
Until then moving the cpufreq_update_util shouldn't be a problem anymore,
it doesn't depend on enqueue/dequeue (actually at context_switch, the
currently present hack can be removed.)
(context is
https://lore.kernel.org/lkml/20240516204802.846520-1-qyousef@layalina.io/
I assume. The patch is written with the context-switch update in mind
and will be a lot cleaner if that precedes it.)
- UFS device with multi-completion queue benchmarks (Bart):
Sorry haven't gotten my hands on one I can experiment nicely with.
- Peter's comments about the design of the tracking.
I agree that it's complexity is hard to swallow, but "iowait wakeup" is
very little information to work with. I don't see a way that provides
us with some inference on whether the boost was effective and worth
keeping (while still being reasonably on par with previous sugov iowait
boosting performance and an acceptable ramp-up time).
The current design must evolve if we want to do per-task tracking and
therefore already necessarily comes with increased complexity that
needs to be justified, the proposed design at least adds potential
power-savings during IO workloads as a benefit.

Hi Pengfei,
I reviewed this commit multiple times, but I still couldn't figure out why this
commit would cause this issue. Could someone else please take a look? Thank you

>
> How to reproduce:
> git clone https://gitlab.com/xupengfe/repro_vm_env.git
> cd repro_vm_env
> tar -xvf repro_vm_env.tar.gz
> cd repro_vm_env; ./start3.sh // it needs qemu-system-x86_64 and I used v7.1.0
> // start3.sh will load bzImage_2241ab53cbb5cdb08a6b2d4688feb13971058f65 v6.2-rc5 kernel
> // You could change the bzImage_xxx as you want
> // Maybe you need to remove line "-drive if=pflash,format=raw,readonly=on,file=./OVMF_CODE.fd \" for different qemu version
> You could use below command to log in, there is no password for root.
> ssh -p 10023 root@localhost
>
> After login vm(virtual machine) successfully, you could transfer reproduced
> binary to the vm by below way, and reproduce the problem in vm:
> gcc -pthread -o repro repro.c
> scp -P 10023 repro root@localhost:/root/
>
> Get the bzImage for target kernel:
> Please use target kconfig and copy it to kernel_src/.config
> make olddefconfig
> make -jx bzImage //x should equal or less than cpu num your pc has
>
> Fill the bzImage file into above start3.sh to load the target kernel in vm.
>
>
> Tips:
> If you already have qemu-system-x86_64, please ignore below info.
> If you want to install qemu v7.1.0 version:
> git clone https://github.com/qemu/qemu.git
> cd qemu
> git checkout -f v7.1.0
> mkdir build
> cd build
> yum install -y ninja-build.x86_64
> yum -y install libslirp-devel.x86_64
> ../configure --target-list=x86_64-softmmu --enable-kvm --enable-vnc --enable-gtk --enable-sdl --enable-usb-redir --enable-slirp
