Pull vfs fix from Christian Brauner:
"An openat() call from io_uring triggering an audit call can apparently
cause the refcount of struct filename to be incremented from multiple
threads concurrently during async execution, triggering a refcount
underflow and hitting a BUG_ON(). That bug has been lurking around
since at least v5.16 apparently.
Switch to an atomic counter to fix that. The underflow check is
downgraded from a BUG_ON() to a WARN_ON_ONCE() but we could easily
remove that check altogether tbh"

fine as it added also a definition of __NR_seccomp for 64-bit. But it
failed to do so for 32-bit as instead of ifndef, ifdef was used.
Fix this typo (so fix the build of perf on 32-bit).

This reverts commit 45e34c8af58f23db4474e2bfe79183efec09a18b, and the
two subsequent fixes to it:
3f874c9b2aae ("x86/smp: Don't send INIT to non-present and non-booted CPUs")
b1472a60a584 ("x86/smp: Don't send INIT to boot CPU")
because it seems to result in hung machines at shutdown. Particularly
some Dell machines, but Thomas says
"The rest seems to be Lenovo and Sony with Alderlake/Raptorlake CPUs -
at least that's what I could figure out from the various bug reports.
I don't know which CPUs the DELL machines have, so I can't say it's a
pattern.
I agree with the revert for now"
Ashok Raj chimes in:
"There was a report (probably this same one), and it turns out it was a
bug in the BIOS SMI handler.
The client BIOS's were waiting for the lowest APICID to be the SMI
rendevous master. If this is MeteorLake, the BSP wasn't the one with
the lowest APIC and it triped here.
The BIOS change is also being pushed to others for assimilation :)
Server BIOS's had this correctly for a while now"
and it does look likely to be some bad interaction between SMI and the
non-BSP cores having put into INIT (and thus unresponsive until reset).

Commit 295525e29a5b ("virtio_net: merge dma operations when filling
mergeable buffers") unmaps the buffer with DMA_ATTR_SKIP_CPU_SYNC when
the dma->ref is zero. We do that with DMA_ATTR_SKIP_CPU_SYNC, because we
do not want to do the sync for the entire page_frag. But that misses the
sync for the current area.
This patch does cpu sync regardless of whether the ref is zero or not.

After commit f6fca3917b4d and 5da431b71d4b, the sequence of events for
a data chunk allocation on a non-zoned filesystem is:
1. btrfs_create_chunk calls init_alloc_chunk_ctl, which copies
space_info->chunk_size (default 10 GiB) to ctl->max_stripe_len
unmodified. Before f6fca3917b4d, ctl->max_stripe_len value was
1 GiB for non-zoned data chunks and not configurable.
2. btrfs_create_chunk calls gather_device_info which consumes
and produces more fields of chunk_ctl.
3. gather_device_info multiplies ctl->max_stripe_len by
ctl->dev_stripes (which is 1 in all cases except dup)
and calls find_free_dev_extent with that number as num_bytes.
4. find_free_dev_extent locates the first dev_extent hole on
a device which is at least as large as num_bytes. With default
max_chunk_size from f6fca3917b4d, it finds the first hole which is
longer than 10 GiB, or the largest hole if that hole is shorter
than 10 GiB. This is different from the pre-f6fca3917b4d
behavior, where num_bytes is 1 GiB, and find_free_dev_extent
may choose a different hole.
5. gather_device_info repeats step 4 with all devices to find
the first or largest dev_extent hole that can be allocated on
each device.
6. gather_device_info sorts the device list by the hole size
on each device, using total unallocated space on each device to
break ties, then returns to btrfs_create_chunk with the list.
7. btrfs_create_chunk calls decide_stripe_size_regular.
8. decide_stripe_size_regular finds the largest stripe_len that
fits across the first nr_devs device dev_extent holes that were
found by gather_device_info (and satisfies other constraints
on stripe_len that are not relevant here).
9. decide_stripe_size_regular caps the length of the stripe it
computed at 1 GiB. This cap appeared in 5da431b71d4b to correct
one of the other regressions introduced in f6fca3917b4d.
10. btrfs_create_chunk creates a new chunk with the above
computed size and number of devices.
At step 4, gather_device_info() has found a location where stripe up to
10 GiB in length could be allocated on several devices, and selected
which devices should have a dev_extent allocated on them, but at step
9, only 1 GiB of the space that was found on each device can be used.
This mismatch causes new suboptimal chunk allocation cases that did not
occur in pre-f6fca3917b4d kernels.
Consider a filesystem using raid1 profile with 3 devices. After some
balances, device 1 has 10x 1 GiB unallocated space, while devices 2
and 3 have 1x 10 GiB unallocated space, i.e. the same total amount of
space, but distributed across different numbers of dev_extent holes.
For visualization, let's ignore all the chunks that were allocated before
this point, and focus on the remaining holes:
Device 1: [_] [_] [_] [_] [_] [_] [_] [_] [_] [_] (10x 1 GiB unallocated)
Device 2: [__________] (10 GiB contig unallocated)
Device 3: [__________] (10 GiB contig unallocated)
Before f6fca3917b4d, the allocator would fill these optimally by
allocating chunks with dev_extents on devices 1 and 2 ([12]), 1 and 3
([13]), or 2 and 3 ([23]):
[after 0 chunk allocations]
Device 1: [_] [_] [_] [_] [_] [_] [_] [_] [_] [_] (10 GiB)
Device 2: [__________] (10 GiB)
Device 3: [__________] (10 GiB)
[after 1 chunk allocation]
Device 1: [12] [_] [_] [_] [_] [_] [_] [_] [_] [_]
Device 2: [12] [_________] (9 GiB)
Device 3: [__________] (10 GiB)
[after 2 chunk allocations]
Device 1: [12] [13] [_] [_] [_] [_] [_] [_] [_] [_] (8 GiB)
Device 2: [12] [_________] (9 GiB)
Device 3: [13] [_________] (9 GiB)
[after 3 chunk allocations]
Device 1: [12] [13] [12] [_] [_] [_] [_] [_] [_] [_] (7 GiB)
Device 2: [12] [12] [________] (8 GiB)
Device 3: [13] [_________] (9 GiB)
[...]
[after 12 chunk allocations]
Device 1: [12] [13] [12] [13] [12] [13] [12] [13] [_] [_] (2 GiB)
Device 2: [12] [12] [23] [23] [12] [12] [23] [23] [__] (2 GiB)
Device 3: [13] [13] [23] [23] [13] [23] [13] [23] [__] (2 GiB)
[after 13 chunk allocations]
Device 1: [12] [13] [12] [13] [12] [13] [12] [13] [12] [_] (1 GiB)
Device 2: [12] [12] [23] [23] [12] [12] [23] [23] [12] [_] (1 GiB)
Device 3: [13] [13] [23] [23] [13] [23] [13] [23] [__] (2 GiB)
[after 14 chunk allocations]
Device 1: [12] [13] [12] [13] [12] [13] [12] [13] [12] [13] (full)
Device 2: [12] [12] [23] [23] [12] [12] [23] [23] [12] [_] (1 GiB)
Device 3: [13] [13] [23] [23] [13] [23] [13] [23] [13] [_] (1 GiB)
[after 15 chunk allocations]
Device 1: [12] [13] [12] [13] [12] [13] [12] [13] [12] [13] (full)
Device 2: [12] [12] [23] [23] [12] [12] [23] [23] [12] [23] (full)
Device 3: [13] [13] [23] [23] [13] [23] [13] [23] [13] [23] (full)
This allocates all of the space with no waste. The sorting function used
by gather_device_info considers free space holes above 1 GiB in length
to be equal to 1 GiB, so once find_free_dev_extent locates a sufficiently
long hole on each device, all the holes appear equal in the sort, and the
comparison falls back to sorting devices by total free space. This keeps
usable space on each device equal so they can all be filled completely.
After f6fca3917b4d, the allocator prefers the devices with larger holes
over the devices with more free space, so it makes bad allocation choices:
[after 1 chunk allocation]
Device 1: [_] [_] [_] [_] [_] [_] [_] [_] [_] [_] (10 GiB)
Device 2: [23] [_________] (9 GiB)
Device 3: [23] [_________] (9 GiB)
[after 2 chunk allocations]
Device 1: [_] [_] [_] [_] [_] [_] [_] [_] [_] [_] (10 GiB)
Device 2: [23] [23] [________] (8 GiB)
Device 3: [23] [23] [________] (8 GiB)
[after 3 chunk allocations]
Device 1: [_] [_] [_] [_] [_] [_] [_] [_] [_] [_] (10 GiB)
Device 2: [23] [23] [23] [_______] (7 GiB)
Device 3: [23] [23] [23] [_______] (7 GiB)
[...]
[after 9 chunk allocations]
Device 1: [_] [_] [_] [_] [_] [_] [_] [_] [_] [_] (10 GiB)
Device 2: [23] [23] [23] [23] [23] [23] [23] [23] [23] [_] (1 GiB)
Device 3: [23] [23] [23] [23] [23] [23] [23] [23] [23] [_] (1 GiB)
[after 10 chunk allocations]
Device 1: [12] [_] [_] [_] [_] [_] [_] [_] [_] [_] (9 GiB)
Device 2: [23] [23] [23] [23] [23] [23] [23] [23] [12] (full)
Device 3: [23] [23] [23] [23] [23] [23] [23] [23] [_] (1 GiB)
[after 11 chunk allocations]
Device 1: [12] [13] [_] [_] [_] [_] [_] [_] [_] [_] (8 GiB)
Device 2: [23] [23] [23] [23] [23] [23] [23] [23] [12] (full)
Device 3: [23] [23] [23] [23] [23] [23] [23] [23] [13] (full)
No further allocations are possible, with 8 GiB wasted (4 GiB of data
space). The sort in gather_device_info now considers free space in
holes longer than 1 GiB to be distinct, so it will prefer devices 2 and
3 over device 1 until all but 1 GiB is allocated on devices 2 and 3.
At that point, with only 1 GiB unallocated on every device, the largest
hole length on each device is equal at 1 GiB, so the sort finally moves
to ordering the devices with the most free space, but by this time it
is too late to make use of the free space on device 1.
Note that it's possible to contrive a case where the pre-f6fca3917b4d
allocator fails the same way, but these cases generally have extensive
dev_extent fragmentation as a precondition (e.g. many holes of 768M
in length on one device, and few holes 1 GiB in length on the others).
With the regression in f6fca3917b4d, bad chunk allocation can occur even
under optimal conditions, when all dev_extent holes are exact multiples
of stripe_len in length, as in the example above.
Also note that post-f6fca3917b4d kernels do treat dev_extent holes
larger than 10 GiB as equal, so the bad behavior won't show up on a
freshly formatted filesystem; however, as the filesystem ages and fills
up, and holes ranging from 1 GiB to 10 GiB in size appear, the problem
can show up as a failure to balance after adding or removing devices,
or an unexpected shortfall in available space due to unequal allocation.
To fix the regression and make data chunk allocation work
again, set ctl->max_stripe_len back to the original SZ_1G, or
space_info->chunk_size if that's smaller (the latter can happen if the
user set space_info->chunk_size to less than 1 GiB via sysfs, or it's
a 32 MiB system chunk with a hardcoded chunk_size and stripe_len).
While researching the background of the earlier commits, I found that an
identical fix was already proposed at:
https://lore.kernel.org/linux-btrfs/de83ac46-a4a3-88d3-85ce-255b7abc5249@gmx.com/
The previous review missed one detail: ctl->max_stripe_len is used
before decide_stripe_size_regular() is called, when it is too late for
the changes in that function to have any effect. ctl->max_stripe_len is
not used directly by decide_stripe_size_regular(), but the parameter
does heavily influence the per-device free space data presented to
the function.

Kernel v6.5 converted overlayfs to new mount api.
As an added bonus, it also added a feature to allow appending lowerdirs
using lowerdir=:/lower2,lowerdir=::/data3 syntax.
This new syntax has raised some concerns regarding escaping of colons.
We decided to try and disable this syntax, which hasn't been in the wild
for so long and introduce it again in 6.7 using explicit mount options
lowerdir+=/lower2,datadir+=/data3.

Before commit b36a5780cb44 ("ovl: modify layer parameter parsing"),
spaces and commas in lowerdir mount option value used to be escaped using
seq_show_option().
In current upstream, when lowerdir value has a space, it is not escaped
in /proc/mounts, e.g.:
none /mnt overlay rw,relatime,lowerdir=l l,upperdir=u,workdir=w 0 0
which results in broken output of the mount utility:
none on /mnt type overlay (rw,relatime,lowerdir=l)
Store the original lowerdir mount options before unescaping and show
them using the same escaping used for seq_show_option() in addition to
escaping the colon separator character.

Touch controllers need some time after receiving reset command for the
firmware to finish re-initializing and be ready to respond to commands
from the host. The driver already had handling for the post-reset delay
for I2C and SPI transports, this change adds the handling to
SMBus-connected devices.
SMBus devices are peculiar because they implement legacy PS/2
compatibility mode, so reset is actually issued by psmouse driver on the
associated serio port, after which the control is passed to the RMI4
driver with SMBus companion device.
Note that originally the delay was added to psmouse driver in
92e24e0e57f7 ("Input: psmouse - add delay when deactivating for SMBus
mode"), but that resulted in an unwanted delay in "fast" reconnect
handler for the serio port, so it was decided to revert the patch and
have the delay being handled in the RMI4 driver, similar to the other
transports.

When the SMBus connection is attempted psmouse_smbus_init() sets
the fast_reconnect pointer to psmouse_smbus_reconnecti(). If SMBus
initialization fails, elantech_setup_ps2() and synaptics_init_ps2() will
fallback to PS/2 mode, replacing the psmouse private data. This can cause
issues on resume, since psmouse_smbus_reconnect() expects to find an
instance of struct psmouse_smbus_dev in psmouse->private.
The issue was uncovered when in 92e24e0e57f7 ("Input: psmouse - add
delay when deactivating for SMBus mode") psmouse_smbus_reconnect()
started attempting to use more of the data structure. The commit was
since reverted, not because it was at fault, but because there was found
a better way of doing what it was attempting to do.
Fix the problem by resetting the fast_reconnect pointer in psmouse
structure in elantech_setup_ps2() and synaptics_init_ps2() when the PS/2
mode is used.

An io_uring openat operation can update an audit reference count
from multiple threads resulting in the call trace below.
A call to io_uring_submit() with a single openat op with a flag of
IOSQE_ASYNC results in the following reference count updates.
These first part of the system call performs two increments that do not race.
do_syscall_64()
__do_sys_io_uring_enter()
io_submit_sqes()
io_openat_prep()
__io_openat_prep()
getname()
getname_flags() /* update 1 (increment) */
__audit_getname() /* update 2 (increment) */
The openat op is queued to an io_uring worker thread which starts the
opportunity for a race. The system call exit performs one decrement.
do_syscall_64()
syscall_exit_to_user_mode()
syscall_exit_to_user_mode_prepare()
__audit_syscall_exit()
audit_reset_context()
putname() /* update 3 (decrement) */
The io_uring worker thread performs one increment and two decrements.
These updates can race with the system call decrement.
io_wqe_worker()
io_worker_handle_work()
io_wq_submit_work()
io_issue_sqe()
io_openat()
io_openat2()
do_filp_open()
path_openat()
__audit_inode() /* update 4 (increment) */
putname() /* update 5 (decrement) */
__audit_uring_exit()
audit_reset_context()
putname() /* update 6 (decrement) */
The fix is to change the refcnt member of struct audit_names
from int to atomic_t.

* tag 'acpi-6.6-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
ACPI: resource: Add TongFang GM6BGEQ, GM6BG5Q and GM6BG0Q to irq1_edge_low_force_override[]
ACPI: EC: Add quirk for the HP Pavilion Gaming 15-dk1xxx
ACPI: resource: Skip IRQ override on ASUS ExpertBook B1402CBA
* A handful of build fixes.
* A fix to avoid mixing up user/kernel-mode breakpoints, which can
manifest as a hang when mixing k/uprobes with other breakpoint
sources.
* A fix to avoid double-allocting crash kernel memory.
* A fix for tracefs syscall name mangling, which was causing syscalls
not to show up in tracefs.
* A fix to the perf driver to enable the hw events when selected, which
can trigger a BUG on some userspace access patterns.
