The kernel is now built with -fms-extensions. Anonymous structs or
unions permitted by these extensions have been used in several places,
and can end up in the generated vmlinux.h file, for example:
struct ns_tree {
[...]
};
[...]
struct ns_common {
[...]
union {
struct ns_tree;
struct callback_head ns_rcu;
};
};
Trying to include this header for compiling a tool may result in build
warnings, if the compiler does not expect these extensions. This is the
case, for example, with bpftool:
In file included from skeleton/pid_iter.bpf.c:3:
.../tools/testing/selftests/bpf/tools/build/bpftool/vmlinux.h:64057:3:
warning: declaration does not declare anything
[-Wmissing-declarations]
64057 | struct ns_tree;
| ^~~~~~~~~~~~~~
Fix these build warnings in bpftool by turning on Microsoft extensions
when compiling the two BPF programs that rely on vmlinux.h.

On SMP systems the CPU hotplug callbacks in the "starting" range are
invoked while the CPU is brought up and interrupts are still
disabled. Callbacks which are added later are invoked via the
hotplug-thread on the target CPU and interrupts are explicitly disabled.
In the UP case callbacks which are added later are invoked directly without
the thread indirection. This is in principle okay since there is just one
CPU but those callbacks are invoked with interrupt disabled code. That's
incorrect as those callbacks assume interrupt disabled context.
Disable interrupts before invoking the callbacks on UP if the state is
atomic and interrupts are expected to be disabled. The "save" part is
required because this is also invoked early in the boot process while
interrupts are disabled and must not be enabled prematurely.

When mounting a btrfs file system on virtio-blk which supports native
Zone Append there has been a WARN triggering in btrfs' space management
code.
Further looking into btrfs' zoned statistics uncovered the filesystem
expecting the zones to be used, but the write pointers being 0:
# cat /sys/fs/btrfs/8eabd2e7-3294-4f9e-9b58-7e64135c8bf4/zoned_stats
active block-groups: 4
reclaimable: 0
unused: 0
need reclaim: false
data relocation block-group: 1342177280
active zones:
start: 1073741824, wp: 0 used: 0, reserved: 0, unusable: 0
start: 1342177280, wp: 0 used: 0, reserved: 0, unusable: 0
start: 1610612736, wp: 0 used: 16384, reserved: 0, unusable: 18446744073709535232
start: 1879048192, wp: 0 used: 131072, reserved: 0, unusable: 18446744073709420544
Looking at the blkzone report output for the zone in question
(1610612736) the write pointer on the device moved, but the filesystem
did not see a change on the write pointer:
# blkzone report -c 1 -o 0x300000 /dev/vda
start: 0x000300000, len 0x080000, cap 0x080000, wptr 0x000040 reset:0 non-seq:0, zcond: 2(oi) [type: 2(SEQ_WRITE_REQUIRED)]
The zone write pointer is 0, because btrfs is using the cached version
of blkdev_report_zones() and as virtio-blk is supporting native zone
append, but blkdev_revalidate_zones() does not initialize the zone write
plugs in this case.
Not skipping the revalidate of sequential zones in
blkdev_revalidate_zones() callchain fixes this issue.

Building the KVM intel module failed to build with UT=1:

make[3]: *** [/work/git/test-linux.git/scripts/Makefile.modfinal:62: arch/x86/kvm/kvm-intel.ko] Error 1
The reason is that the module only uses the tracepoints defined and
exported by the main kvm module. The tracepoint-update.c code fails the
build if a tracepoint is used, but there's no tracepoints defined. But
this is acceptable in modules if the tracepoints are defined in the vmlinux
proper or another module and exported.
Do not fail to build if a tracepoint is used but no tracepoints are
defined if the code is a module. This should still never happen for the
vmlinux itself.

Using min_wait, two timeouts are given:
1) The min_wait timeout, within which up to 'wait_nr' events are
waited for.
2) The overall long timeout, which is entered if no events are generated
in the min_wait window.
If the min_wait has expired, any event being posted must wake the task.
For SQPOLL, that isn't the case, as it won't trigger the io_has_work()
condition, as it will have already processed the task_work that happened
when an event was posted. This causes any event to trigger post the
min_wait to not always cause the waiting application to wakeup, and
instead it will wait until the overall timeout has expired. This can be
shown in a test case that has a 1 second min_wait, with a 5 second
overall wait, even if an event triggers after 1.5 seconds:
axboe@m2max-kvm /d/iouring-mre (master)> zig-out/bin/iouring
info: MIN_TIMEOUT supported: true, features: 0x3ffff
info: Testing: min_wait=1000ms, timeout=5s, wait_nr=4
info: 1 cqes in 5000.2ms
where the expected result should be:
axboe@m2max-kvm /d/iouring-mre (master)> zig-out/bin/iouring
info: MIN_TIMEOUT supported: true, features: 0x3ffff
info: Testing: min_wait=1000ms, timeout=5s, wait_nr=4
info: 1 cqes in 1500.3ms
When the min_wait timeout triggers, reset the number of completions
needed to wake the task. This should ensure that any future events will
wake the task, regardless of how many events it originally wanted to
wait for.

Merge the two ksimd scopes in the implementation of SM4-XTS to prevent

The ciphertext stealing logic in the AES-XTS implementation creates a
separate ksimd scope to call into the FP/SIMD core routines, and in some
cases (CONFIG_KASAN_STACK is one, but there might be others), the 528
byte kernel mode FP/SIMD buffer that is allocated inside this scope is
not shared with the preceding ksimd scope, resulting in unnecessary
stack bloat.
Considering that
a) the XTS ciphertext stealing logic is never called for block
encryption use cases, and XTS is rarely used for anything else,
b) in the vast majority of cases, the entire input block is processed
during the first iteration of the loop,
we can combine both ksimd scopes into a single one with no practical
impact on how often/how long FP/SIMD is en/disabled, allowing us to
reuse the same stack slot for both FP/SIMD routine calls.

As we're doing in the BLAKE2b code, use unrolled_full to make the

BLAKE2b has a state of 16 64-bit words. Add the message data in and
there are 32 64-bit words. With the current code where all the rounds
are unrolled to enable constant-folding of the blake2b_sigma values,
this results in a very large code size on 32-bit kernels, including a
recurring issue where gcc uses a large amount of stack.
There's just not much benefit to this unrolling when the code is already
so large. Let's roll up the rounds when !CONFIG_64BIT.
To avoid having to duplicate the code, just write the code once using a
loop, and conditionally use 'unrolled_full' from <linux/unroll.h>.
Then, fold the now-unneeded ROUND() macro into the loop. Finally, also
remove the now-unneeded override of the stack frame size warning.
Code size improvements for blake2b_compress_generic():
Size before (bytes) Size after (bytes)
------------------- ------------------
i386, gcc 27584 3632
i386, clang 18208 3248
arm32, gcc 19912 2860
arm32, clang 21336 3344
Running the BLAKE2b benchmark on a !CONFIG_64BIT kernel on an x86_64
processor shows a 16384B throughput change of 351 => 340 MB/s (gcc) or
442 MB/s => 375 MB/s (clang). So clearly not much of a slowdown either.
But also that microbenchmark also effectively disregards cache usage,
which is important in practice and is far better in the smaller code.
Note: If we rolled up the loop on x86_64 too, the change would be
7024 bytes => 1584 bytes and 1960 MB/s => 1396 MB/s (gcc), or
6848 bytes => 1696 bytes and 1920 MB/s => 1263 MB/s (clang).
Maybe still worth it, though not quite as clearly beneficial.

Replace the RISCV_ISA_V dependency of the RISC-V crypto code with
RISCV_EFFICIENT_VECTOR_UNALIGNED_ACCESS, which implies RISCV_ISA_V as
well as vector unaligned accesses being efficient.
This is necessary because this code assumes that vector unaligned
accesses are supported and are efficient. (It does so to avoid having
to use lots of extra vsetvli instructions to switch the element width
back and forth between 8 and either 32 or 64.)
This was omitted from the code originally just because the RISC-V kernel
support for detecting this feature didn't exist yet. Support has now
been added, but it's fragmented into per-CPU runtime detection, a
command-line parameter, and a kconfig option. The kconfig option is the
only reasonable way to do it, though, so let's just rely on that.

v2 survivability breadcrumbs introduces a new mode called
SPI Flash Descriptor Override mode (FDO). This is enabled by
PCODE when MEI itself fails and firmware cannot be updated via
MEI using igsc. This mode provides the ability to update
the firmware directly via SPI driver.
Xe KMD initializes the nvm aux driver if FDO mode is enabled.
Userspace should check FDO mode entry in survivability info sysfs before
using the SPI driver to update firmware.
/sys/bus/pci/devices/<device>/survivability_info/fdo_mode

Redesign survivability mode to have only one value per file.
1) Retain the survivability_mode sysfs to indicate the type
cat /sys/bus/pci/devices/0000\:03\:00.0/survivability_mode
(Boot / Runtime)
2) Add survivability_info directory to expose boot breadcrumbs.
Entries in survivability mode sysfs are only visible when
boot breadcrumb registers are populated.
/sys/bus/pci/devices/0000:03:00.0/survivability_info
├── aux_info0
├── aux_info1
├── aux_info2
├── aux_info3
├── aux_info4
├── capability_info
├── postcode_trace
└── postcode_trace_overflow
Capability Info:
Provides data about boot status and has bits that
indicate the support for the other breadcrumbs
Postcode Trace / Postcode Trace Overflow :
Each postcode is represented as an 8-bit value and represents
a boot failure event. When a new failure event is logged by Pcode
the existing postcodes are shifted left. These entries provide a
history of 8 postcodes.
Auxiliary Info:
Some failures have additional debug information.

happy with using it. Note that for this the return value has to be
double-inverted as the return value convention of lockref_put_or_lock
is inverted compared to _trylock conventions expected by __cond_lock,
as lockref_put_or_lock returns true when it did not need to take the

When autosuspend is triggered, driver rpm_on flag is set to indicate that
a suspend/resume is already in progress. However, when a userspace
application submits a command during this narrow window,
amdxdna_pm_resume_get() may incorrectly skip the resume operation because
the rpm_on flag is still set. This results in commands being submitted
while the device has not actually resumed, causing unexpected behavior.
The set_dpm() is called by suspend/resume, it relied on rpm_on flag to
avoid calling into rpm suspend/resume recursivly. So to fix this, remove
the use of the rpm_on flag entirely. Instead, introduce aie2_pm_set_dpm()
which explicitly resumes the device before invoking set_dpm(). With this
change, set_dpm() is called directly inside the suspend or resume execution
path. Otherwise, aie2_pm_set_dpm() is called.

If wait for ring space started just before migration, it can delay
the recovery process, by waiting without bailout path for up to 2
seconds.
Two second wait for recovery is not acceptable, and if the ring was
completely filled even without the migration temporarily stopping
execution, then such a wait will result in up to a thousand new jobs
(assuming constant flow) being added while the wait is happening.
While this will not cause data corruption, it will lead to warning
messages getting logged due to reset being scheduled on a GT under
recovery. Also several seconds of unresponsiveness, as the backlog
of jobs gets progressively executed.
Add a bailout condition, to make sure the recovery starts without
much delay. The recovery is expected to finish in about 100 ms when
under moderate stress, so the condition verification period needs to be
below that - settling at 64 ms.
The theoretical max time which the recovery can take depends on how
many requests can be emitted to engine rings and be pending execution.
While stress testing, it was possible to reach 10k pending requests
on rings when a platform with two GTs was used. This resulted in max
recovery time of 5 seconds. But in real life situations, it is very
unlikely that the amount of pending requests will ever exceed 100,
and for that the recovery time will be around 50 ms - well within our
claimed limit of 100ms.

The function hugetlb_reserve_pages() returns the number of pages added
to the reservation map on success and a negative error code on failure
(e.g. -EINVAL, -ENOMEM). However, in some error paths, it may return -1
directly.
For example, a failure at:
if (hugetlb_acct_memory(h, gbl_reserve) < 0)
goto out_put_pages;
results in returning -1 (since add = -1), which may be misinterpreted
in userspace as -EPERM.
Fix this by explicitly capturing and propagating the return values from
helper functions, and using -EINVAL for all other failure cases.

min_order_for_split() returns -EBUSY when the folio is truncated and
cannot be split. In commit 77008e1b2ef7 ("mm/huge_memory: do not change
split_huge_page*() target order silently"), memory_failure() does not
handle it and pass -EBUSY to try_to_split_thp_page() directly.
try_to_split_thp_page() returns -EINVAL since -EBUSY becomes 0xfffffff0 as
new_order is unsigned int in __folio_split() and this large new_order is
rejected as an invalid input. The code does not cause a bug.
soft_offline_in_use_page() also uses min_order_for_split() but it always
passes 0 as new_order for split.
Fix it by making min_order_for_split() always return an order. When the
given folio is truncated, namely folio->mapping == NULL, return 0 and let
a subsequent split function handle the situation and return -EBUSY.
Add kernel-doc to min_order_for_split() to clarify its use.

can_split_folio() is just a refcount comparison, making sure only the
split caller holds an extra pin. Open code it with
folio_expected_ref_count() != folio_ref_count() - 1. For the extra_pins
used by folio_ref_freeze(), add folio_cache_ref_count() to calculate it.
Also replace folio_expected_ref_count() with folio_cache_ref_count() used
by folio_ref_unfreeze(), since they are returning the same values when a
folio is frozen and folio_cache_ref_count() does not have unnecessary
folio_mapcount() in its implementation.

Patch series "Improve folio split related functions", v4.
This patchset improves several folio split related functions to avoid
future misuse. The changes are:
1. Consolidated folio splittable checks by moving truncated folio check,
huge zero folio check, and writeback folio check into
folio_split_supported(). Changed the function return type. Renamed it
to folio_check_splittable() for clarification.
2. Replaced can_split_folio() with open coded folio_expected_ref_count()
and folio_ref_count() and introduced folio_cache_ref_count().
3. Changed min_order_for_split() to always return an order.
4. Fixed folio split stats counting.
Motivation
==========
This is based on Wei's observation[1] and solves several potential
issues:
1. Dereferencing NULL folio->mapping in try_folio_split_to_order() if it
is called on truncated folios.
2. Not handling of negative return value of min_order_for_split() in
mm/memory-failure.c
There is no bug in the current code.
This patch (of 4):
folio_split_supported() used in try_folio_split_to_order() requires
folio->mapping to be non NULL, but current try_folio_split_to_order() does
not check it. There is no issue in the current code, since
try_folio_split_to_order() is only used in truncate_inode_partial_folio(),
where folio->mapping is not NULL.
To prevent future misuse, move folio->mapping NULL check (i.e., folio is
truncated) into folio_split_supported(). Since folio->mapping NULL check
returns -EBUSY and folio_split_supported() == false means -EINVAL, change
folio_split_supported() return type from bool to int and return error
numbers accordingly. Rename folio_split_supported() to
folio_check_splittable() to match the return type change.
While at it, move is_huge_zero_folio() check and folio_test_writeback()
check into folio_check_splittable() and add kernel-doc.
Remove all warnings inside folio_check_splittable() and give warnings
in __folio_split() instead, so that bool warns parameter can be removed.
