The wait_for_completion_timeout function returns 0 if timed out or a
positive value if completed. Hence, "less than zero" comparison always
misses timeouts and doesn't kill the URB as it should, leading to
re-sending it while it is active.

The previous commit fixed handling of incomplete packets but broke error
handling: offsetof returns an unsigned value (size_t), but when compared
against the signed return value, the return value is interpreted as if
it were unsigned, so negative return values are never less than the
offset.
To make the code easier to read, calculate the minimal packet length
once and separately, and assign it to a signed int variable to eliminate
unsigned math and the need for type casts. It then becomes immediately
obvious how the actual data length is calculated and why the return
value cannot be less than the minimal length.

Some Apple ISO keyboards have a quirk where the backtick/tilde key is
swapped with the less-than/greater-than key. Unfortunately, there is no
perfectly reliable way to detect whether a keyboard has the quirk or
not, but the quirk appears to only be present on models that support
Bluetooth, and the affected keyboards usually report country code 13 in
the HID descriptor.
Therefore, the best we can do is to change
/sys/module/hid_apple/parameters/iso_layout to a ternary:
0 = Not ISO or ISO and not quirky
1 = ISO and quirky
-1 = Guess based on product ID and country code

When a finger is on the screen, the UPERFECT Y portable touchscreen
monitor reports a contact in the first place. However, after this
initial report, contacts are not reported at the refresh rate of the
screen as required by the Windows 8 specs.
This behaviour triggers the release_timer, removing the fingers even
though they are still present.
To avoid it, add a new class, similar to MT_CLS_WIN_8 but without the
MT_QUIRK_STICKY_FINGERS quirk for this device.

Since the actual_length calculation is performed unsigned, packets
shorter than 7 bytes (e.g. packets without data or otherwise truncated)
or non-received packets ("zero" bytes) can cause buffer overflow.

The problem is the driver assumes the device must have an input report but
some malicious devices violate this assumption.
So this patch checks hid_device's input is non empty before it's been used.

some updates to the basic clk types to use determine_rate for the
divider type and add a power of two fractional divider flag though.
Otherwise, this is a collection of clk driver updates. More than half
the diffstat is in the Qualcomm clk driver where we add a bunch of data
to describe clks on various SoCs and fix bugs. The other big new thing
in here is the Mediatek MT8192 clk driver. That's been under review for
a while and it's nice to see that it's finally upstream.
Beyond that it's the usual set of minor fixes and tweaks to clk drivers.
There are some non-clk driver bits in here which have all been acked by
the respective maintainers.
New Drivers:
- Support video, gpu, display clks on qcom sc7280 SoCs
- GCC clks on qcom MSM8953, SM4250/6115, and SM6350 SoCs
- Multimedia clks (MMCC) on qcom MSM8994/MSM8992
- RPMh clks on qcom SM6350 SoCs
- Support for Mediatek MT8192 SoCs
- Add display (DU and DSI) clocks on Renesas R-Car V3U
- Add I2C, DMAC, USB, sound (SSIF-2), GPIO, CANFD, and ADC clocks and
resets on Renesas RZ/G2L
Updates:
- Support the SD/OE pin on IDT VersaClock 5 and 6 clock generators
- Add power of two flag to fractional divider clk type
- Migrate some clk drivers to clk_divider_ops.determine_rate
- Migrate to clk_parent_data in gcc-sdm660

'kvmalloc()' is a convenience function for people who want to do a
kmalloc() but fall back on vmalloc() if there aren't enough physically
contiguous pages, or if the allocation is larger than what kmalloc()
supports.
However, let's make sure it doesn't get _too_ easy to do crazy things
with it. In particular, don't allow big allocations that could be due
to integer overflow or underflow. So make sure the allocation size fits
in an 'int', to protect against trivial integer conversion issues.

- Fix a potential log livelock on busy filesystems when there's so much
work going on that we can't finish a quotaoff before filling up the log
by removing the ability to disable quota accounting.
- Introduce the ability to use per-CPU data structures in XFS so that
we can do a better job of maintaining CPU locality for certain
operations.
- Defer inode inactivation work to per-CPU lists, which will help us
batch that processing. Deletions of large sparse files will *appear*
to run faster, but all that means is that we've moved the work to the
backend.
- Drop the EXPERIMENTAL warnings from the y2038+ support and the inode
btree counters, since it's been nearly a year and no complaints have
come in.
- Remove more of our bespoke kmem* variants in favor of using the
standard Linux calls.
- Prepare for the addition of log incompat features in upcoming cycles
by actually adding code to support this.
- Small cleanups of the xattr code in preparation for landing support
for full logging of extended attribute updates in a future cycle.
- Replace the various log shutdown state and flag code all over xfs
with a single atomic bit flag.
- Fix a serious log recovery bug where log item replay can be skipped
based on the start lsn of a transaction even though the transaction
commit lsn is the key data point for that by enforcing start lsns to
appear in the log in the same order as commit lsns.
- Enable pipelining in the code that pushes log items to disk.
- Drop ->writepage.
- Fix some bugs in GETFSMAP where the last fsmap record reported for a
device could extend beyond the end of the device, and a separate bug
where query keys for one device could be applied to another.
- Don't let GETFSMAP query functions edit their input parameters.
- Small cleanups to the scrub code's handling of perag structures.
- Small cleanups to the incore inode tree walk code.
- Constify btree function parameters that aren't changed, so that there
will never again be confusion about range query functions changing
their input parameters.
- Standardize the format and names of tracepoint data attributes.
- Clean up all the mount state and feature flags to use wrapped bitset
functions instead of inconsistently open-coded flag checks.
- Fix some confusion between xfs_buf hash table key variable vs. block
number.
- Fix a mis-interaction with iomap where we reported shared delalloc
cow fork extents to iomap, which would cause the iomap unshare
operation to return IO errors unnecessarily.
- Fix DONTCACHE behavior.

Merge tag 'xfs-5.15-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Darrick Wong:
"There's a lot in this cycle.
Starting with bug fixes: To avoid livelocks between the logging code
and the quota code, we've disabled the ability of quotaoff to turn off
quota accounting. (Admins can still disable quota enforcement, but
truly turning off accounting requires a remount.) We've tried to do
this in a careful enough way that there shouldn't be any user visible
effects aside from quotaoff no longer randomly hanging the system.
We've also fixed some bugs in runtime log behavior that could trip up
log recovery if (otherwise unrelated) transactions manage to start and
commit concurrently; some bugs in the GETFSMAP ioctl where we would
incorrectly restrict the range of records output if the two xfs
devices are of different sizes; a bug that resulted in fallocate
funshare failing unnecessarily; and broken behavior in the xfs inode
cache when DONTCACHE is in play.
As for new features: we now batch inode inactivations in percpu
background threads, which sharply decreases frontend thread wait time
when performing file deletions and should improve overall directory
tree deletion times. This eliminates both the problem where closing an
unlinked file (especially on a frozen fs) can stall for a long time,
and should also ease complaints about direct reclaim bogging down on
unlinked file cleanup.
Starting with this release, we've enabled pipelining of the XFS log.
On workloads with high rates of metadata updates to different shards
of the filesystem, multiple threads can be used to format committed
log updates into log checkpoints.
Lastly, with this release, two new features have graduated to
supported status: inode btree counters (for faster mounts), and
support for dates beyond Y2038. Expect these to be enabled by default
in a future release of xfsprogs.
Summary:
- Fix a potential log livelock on busy filesystems when there's so
much work going on that we can't finish a quotaoff before filling
up the log by removing the ability to disable quota accounting.
- Introduce the ability to use per-CPU data structures in XFS so that
we can do a better job of maintaining CPU locality for certain
operations.
- Defer inode inactivation work to per-CPU lists, which will help us
batch that processing. Deletions of large sparse files will
*appear* to run faster, but all that means is that we've moved the
work to the backend.
- Drop the EXPERIMENTAL warnings from the y2038+ support and the
inode btree counters, since it's been nearly a year and no
complaints have come in.
- Remove more of our bespoke kmem* variants in favor of using the
standard Linux calls.
- Prepare for the addition of log incompat features in upcoming
cycles by actually adding code to support this.
- Small cleanups of the xattr code in preparation for landing support
for full logging of extended attribute updates in a future cycle.
- Replace the various log shutdown state and flag code all over xfs
with a single atomic bit flag.
- Fix a serious log recovery bug where log item replay can be skipped
based on the start lsn of a transaction even though the transaction
commit lsn is the key data point for that by enforcing start lsns
to appear in the log in the same order as commit lsns.
- Enable pipelining in the code that pushes log items to disk.
- Drop ->writepage.
- Fix some bugs in GETFSMAP where the last fsmap record reported for
a device could extend beyond the end of the device, and a separate
bug where query keys for one device could be applied to another.
- Don't let GETFSMAP query functions edit their input parameters.
- Small cleanups to the scrub code's handling of perag structures.
- Small cleanups to the incore inode tree walk code.
- Constify btree function parameters that aren't changed, so that
there will never again be confusion about range query functions
changing their input parameters.
- Standardize the format and names of tracepoint data attributes.
- Clean up all the mount state and feature flags to use wrapped
bitset functions instead of inconsistently open-coded flag checks.
- Fix some confusion between xfs_buf hash table key variable vs.
block number.
- Fix a mis-interaction with iomap where we reported shared delalloc
cow fork extents to iomap, which would cause the iomap unshare
operation to return IO errors unnecessarily.
- Fix DONTCACHE behavior"

<debugfs>/printk/index/. It can be used when monitoring important
kernel messages on a farm of various hosts. The monitor has to be

a newly deployed kernel.
- Add printk.console_no_auto_verbose boot parameter. It allows to
generate crash dump even with slow consoles in a reasonable time
frame.
- Remove printk_safe buffers. The messages are always stored directly
to the main logbuffer, even in NMI or recursive context. Also it
allows to serialize syslog operations by a mutex instead of a spin
lock.
