When a CPU hot removal causes a v1 cpuset to lose all its CPUs, the
cpuset hotplug handler will schedule a work function to migrate tasks
in that cpuset with no CPU to its ancestor to enable those tasks to
continue running.
If a strict security policy is in place, however, the task migration
may fail when security_task_setscheduler() call in cpuset_can_attach()
returns a -EACCES error. That will mean that those tasks will have
no CPU to run on. The system administrators will have to explicitly
intervene to either add CPUs to that cpuset or move the tasks elsewhere
if they are aware of it.
This problem was found by a reported test failure in the LTP's
cpuset_hotplug_test.sh. Fix this problem by treating this special case as
an exception to skip the setsched security check in cpuset_can_attach()
when a v1 cpuset with tasks have no CPU left.
With that patch applied, the cpuset_hotplug_test.sh test can be run
successfully without failure.

The Lenovo Yoga Pro 7 14IMH9 (DMI: 83E2) shares PCI SSID 17aa:3847
with the Legion 7 16ACHG6, but has a different codec subsystem ID
(17aa:38cf). The existing SND_PCI_QUIRK for 17aa:3847 applies
ALC287_FIXUP_LEGION_16ACHG6, which attempts to initialize an external
I2C amplifier (CLSA0100) that is not present on the Yoga Pro 7 14IMH9.
As a result, pin 0x17 (bass speakers) is connected to DAC 0x06 which
has no volume control, making hardware volume adjustment completely
non-functional. Audio is either silent or at maximum volume regardless
of the slider position.
Add a HDA_CODEC_QUIRK entry using the codec subsystem ID (17aa:38cf)
to correctly identify the Yoga Pro 7 14IMH9 and apply
ALC287_FIXUP_YOGA9_14IMH9_BASS_SPK_PIN, which redirects pin 0x17 to
DAC 0x02 and restores proper volume control. The existing Legion entry
is preserved unchanged.
This follows the same pattern used for 17aa:386e, where Legion Y9000X
and Yoga Pro 7 14ARP8 share a PCI SSID but are distinguished via
HDA_CODEC_QUIRK.

This reverts commit c073f07576 ("ASoC: Intel: sof_sdw: select PINCTRL_CS42L43 and SPI_CS42L43")
Currently, SND_SOC_INTEL_SOUNDWIRE_SOF_MACH selects PINCTRL_CS42L43
without also selecting or depending on PINCTRL, despite PINCTRL_CS42L43
depending on PINCTRL.
See the following Kbuild warning:
WARNING: unmet direct dependencies detected for PINCTRL_CS42L43

In response to v1 of this patch [1], Arnd pointed out that there is
no compile-time dependency sof_sdw and the PINCTRL_CS42L43 driver.
After testing, I can confirm that the kernel compiled with
SND_SOC_INTEL_SOUNDWIRE_SOF_MACH enabled and PINCTRL_CS42L43 disabled.
This unmet dependency was detected by kconfirm, a static analysis
tool for Kconfig.

In rt5660_hw_params(), the error path for snd_soc_dai_set_sysclk()
correctly uses rtd->dev as the logging device, but the error path for
snd_soc_dai_set_pll() uses codec_dai->dev instead.
These two devices are distinct:
- rtd->dev is the platform device of the PCM runtime (the Intel HDA/SSP
controller, e.g. 0000:00:1f.3), which owns the machine driver callback.
- codec_dai->dev is the I2C device of the rt5660 codec itself
(i2c-10EC5660:00).
Since hw_params is a machine driver operation and both calls are made
within the same function from the machine driver's context, all error
messages should be attributed to rtd->dev. Using codec_dai->dev for one
of them would suggest the error originates inside the codec driver,
which is misleading.
Align the PLL error log with the sysclk one to use rtd->dev, matching
the convention used by all other Intel board drivers in this directory.

The recent refactoring of xfi driver changed the assignment of
atc->daios[] at atc_get_resources(); now it loops over all enum
DAIOTYP entries while it looped formerly only a part of them.
The problem is that the last entry, SPDIF1, is a special type that
is used only for hw20k1 CTSB073X model (as a replacement of SPDIFIO),
and there is no corresponding definition for hw20k2. Due to the lack
of the info, it caused a kernel crash on hw20k2, which was already
worked around by the commit b045ab3dff ("ALSA: ctxfi: Fix missing
SPDIFI1 index handling").
This patch addresses the root cause of the regression above properly,
simply by skipping the incorrect SPDIF1 type in the parser loop.
For making the change clearer, the code is slightly arranged, too.

The Pin Complex 0x17 (bass/woofer speakers) is incorrectly reported as
unconnected in the BIOS (pin default 0x411111f0 = N/A). This causes the
kernel to configure speaker_outs=0, meaning only the tweeters (pin 0x14)
are used. The result is very low, tinny audio with no bass.
The existing quirk ALC287_FIXUP_YOGA9_14IAP7_BASS_SPK_PIN (already present
in patch_realtek.c for SSID 0x17aa3801) fixes the issue completely.

ep93xx_i2s_enable() calls clk_prepare_enable() on three clocks in
sequence (mclk, sclk, lrclk) without checking the return value of any

enabled are never rolled back, leaking them until the next disable cycle
— which may never come if the stream never started cleanly.
Change ep93xx_i2s_enable() from void to int. Add error checking after

Add a test that creates a 3-CPU kick_wait cycle (A->B->C->A). A BPF
scheduler kicks the next CPU in the ring with SCX_KICK_WAIT on every
enqueue while userspace workers generate continuous scheduling churn via
sched_yield(). Without the preceding fix, this hangs the machine within seconds.

SCX_KICK_WAIT busy-waits in kick_cpus_irq_workfn() using
smp_cond_load_acquire() until the target CPU's kick_sync advances. Because
the irq_work runs in hardirq context, the waiting CPU cannot reschedule and
its own kick_sync never advances. If multiple CPUs form a wait cycle, all
CPUs deadlock.
Replace the busy-wait in kick_cpus_irq_workfn() with resched_curr() to
force the CPU through do_pick_task_scx(), which queues a balance callback
to perform the wait. The balance callback drops the rq lock and enables
IRQs following the sched_core_balance() pattern, so the CPU can process
IPIs while waiting. The local CPU's kick_sync is advanced on entry to
do_pick_task_scx() and continuously during the wait, ensuring any CPU that
starts waiting for us sees the advancement and cannot form cyclic
dependencies.

rtla supports building without libbpf. However, BPF actions
patchset [1] adds an include of bpf/libbpf.h into timerlat_bpf.h,
which breaks build on systems that don't have libbpf headers
installed.
This is a leftover from a draft version of the patchset where
timerlat_bpf_set_action() (which takes a struct bpf_program * argument)
was defined in the header. timerlat_bpf.c already includes bpf/libbpf.h
via timerlat.skel.h when libbpf is present.
Remove the redundant include to fix build on systems without libbpf
headers.

The loop creates a whitespace-stripped copy of the card shortname
where `len < sizeof(card->id)` is used for the bounds check. Since
sizeof(card->id) is 16 and the local id buffer is also 16 bytes,
writing 16 non-space characters fills the entire buffer,
overwriting the terminating nullbyte.
When this non-null-terminated string is later passed to
snd_card_set_id() -> copy_valid_id_string(), the function scans
forward with `while (*nid && ...)` and reads past the end of the
stack buffer, reading the contents of the stack.
A USB device with a product name containing many non-ASCII, non-space
characters (e.g. multibyte UTF-8) will reliably trigger this as follows:
BUG: KASAN: stack-out-of-bounds in copy_valid_id_string
sound/core/init.c:696 [inline]
BUG: KASAN: stack-out-of-bounds in snd_card_set_id_no_lock+0x698/0x74c
sound/core/init.c:718
The off-by-one has been present since commit bafeee5b1f ("ALSA:
snd_usb_caiaq: give better shortname") from June 2009 (v2.6.31-rc1),
which first introduced this whitespace-stripping loop. The original
code never accounted for the null terminator when bounding the copy.
Fix this by changing the loop bound to `sizeof(card->id) - 1`,
ensuring at least one byte remains as the null terminator.

Pull vfs fixes from Christian Brauner:
- Fix netfs_limit_iter() hitting BUG() when an ITER_KVEC iterator
reaches it via core dump writes to 9P filesystems. Add ITER_KVEC
handling following the same pattern as the existing ITER_BVEC code.
- Fix a NULL pointer dereference in the netfs unbuffered write retry
path when the filesystem (e.g., 9P) doesn't set the prepare_write
operation.
- Clear I_DIRTY_TIME in sync_lazytime for filesystems implementing
->sync_lazytime. Without this the flag stays set and may cause
additional unnecessary calls during inode deactivation.
- Increase tmpfs size in mount_setattr selftests. A recent commit
bumped the ext4 image size to 2 GB but didn't adjust the tmpfs
backing store, so mkfs.ext4 fails with ENOSPC writing metadata.
- Fix an invalid folio access in iomap when i_blkbits matches the folio
size but differs from the I/O granularity. The cur_folio pointer
would not get invalidated and iomap_read_end() would still be called
on it despite the IO helper owning it.
- Fix hash_name() docstring.
- Fix read abandonment during netfs retry where the subreq variable
used for abandonment could be uninitialized on the first pass or
point to a deleted subrequest on later passes.
- Don't block sync for filesystems with no data integrity guarantees.
Add a SB_I_NO_DATA_INTEGRITY superblock flag replacing the per-inode
AS_NO_DATA_INTEGRITY mapping flag so sync kicks off writeback but
doesn't wait for flusher threads. This fixes a suspend-to-RAM hang on
fuse-overlayfs where the flusher thread blocks when the fuse daemon
is frozen.
- Fix a lockdep splat in iomap when reads fail. iomap_read_end_io()
invokes fserror_report() which calls igrab() taking i_lock in hardirq
context while i_lock is normally held with interrupts enabled. Kick
failed read handling to a workqueue.
- Remove the redundant netfs_io_stream::front member and use
stream->subrequests.next instead, fixing a potential issue in the
direct write code path.

Merge tag 'ovl-fixes-7.0-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/overlayfs/vfs
Pull overlayfs fixes from Amir Goldstein:
- Fix regression in 'xino' feature detection
I clumsily introduced this regression myself when working on another
subsystem (fsnotify). Both the regression and the fix have almost no
visible impact on users except for some kmsg prints.
- Fix to performance regression in v6.12.
This regression was reported by Google COS developers.
It is not uncommon these days for the year-old mature LTS to get
adopted by distros and get exposed to many new workloads. We made a
sub-smart move of making a behavior change in v6.12 which could
impact performance, without making it opt-in. Fixing this mistake
retroactively, to be picked by LTS.

ovl: make fsync after metadata copy-up opt-in mount option
ovl: fix wrong detection of 32bit inode numbers
Add a test issue an ext4 warning (not a WARN_ON) if there are still
dirty pages attached to an evicted inode.
A lot of ext4 bug fixes including:
* Fix a number of Syzkaller issues.
* Fix memory leaks on error paths.
* Replace some BUG and WARN with EFSCORRUPTED reporting.
* Fix a potential crash when disabling discard via remount followed
by an immediate unmount. (Found by Sashiko)
* Fix a corner case which could lead to allocating blocks for an
indirect-mapped inode block numbers > 2**32.
* Fix a race when reallocating a freed inode that could result in
a deadlock.
* Fix a user-after-free in update_super_work when racing with umount.
* Fix build issues when trying to build ext4's kunit tests as a module
* Fix a bug where ext4_split_extent_zeroout() could fail to pass
back an error from ext4_ext_dirty().
* Avoid allocating blocks from a corrupted block group in
ext4_mb_find_by_goal().
* Fix a percpu_counters list corruption BUG triggered by an
ext4 extents kunit.
* Fix a potetial crash caused by the fast commit flush path potentially
accessing the jinode structure before it is fully initialized.
* Fix fsync(2) in no-journal mode to make sure the dirtied inode is
write to storage.
* Fix a bug when in no-journal mode, when ext4 tries to avoid using
recently deleted inodes, if lazy itable initialization is enabled,
can lead to an unitialized inode getting skipped and triggering
an e2fsck complaint.
* Fix journal credit calculation when setting an xattr when both
the encryption and ea_inode feeatures are enabled.
* Fix corner cases which could result in stale xarray tags after
writeback.
* Fix generic/475 failures caused by ENOSPC errors while creating
a symlink when the system crashes resulting to a file system
inconsistency when replaying the fast commit journal.
