commit 3075476a7af666de3ec10b4f35d8e62db8fd5b6d upstream.
After commit f79473ed9220 ("pm: cpupower: Makefile: Allow overriding
cross-compiling env params") we would fail to cross compile cpupower in
buildroot which uses the recipe at [1] where only the CROSS variable is
being set.
The issue here is the use of the lazy evaluation for all variables: CC,
LD, AR, STRIP, RANLIB, rather than just CROSS.

commit 6e64d6b3a3c39655de56682ec83e894978d23412 upstream.
In commit e4b5ccd392b9 ("drm/v3d: Ensure job pointer is set to NULL
after job completion"), we introduced a change to assign the job pointer
to NULL after completing a job, indicating job completion.
However, this approach created a race condition between the DRM
scheduler workqueue and the IRQ execution thread. As soon as the fence is
signaled in the IRQ execution thread, a new job starts to be executed.
This results in a race condition where the IRQ execution thread sets the
job pointer to NULL simultaneously as the `run_job()` function assigns
a new job to the pointer.
This race condition can lead to a NULL pointer dereference if the IRQ
execution thread sets the job pointer to NULL after `run_job()` assigns
it to the new job. When the new job completes and the GPU emits an
interrupt, `v3d_irq()` is triggered, potentially causing a crash.

Fix the crash by assigning the job pointer to NULL before signaling the
fence. This ensures that the job pointer is cleared before any new job
starts execution, preventing the race condition and the NULL pointer
dereference crash.

commit 66372fa9936088bf29c4f47907efeff03c51a2c8 upstream.
8BitDo Pro 2 Wired Controller shares the same USB identifier
(2dc8:3106) as a different device, so amend name to reflect that and
reduce confusion as the user might think the controller was misdetected.
Because Pro 2 Wired will not work in XTYPE_XBOXONE mode (button presses
won't register), tagging it as XTYPE_XBOX360 remains appropriate.

commit 907bc9268a5a9f823ffa751957a5c1dd59f83f42 upstream.
Microsoft defined Meta+Shift+F23 as the Copilot shortcut instead of a
dedicated keycode, and multiple vendors have their keyboards emit this
sequence in response to users pressing a dedicated "Copilot" key.
Unfortunately the default keymap table in atkbd does not map scancode
0x6e (F23) and so the key combination does not work even if userspace
is ready to handle it.
Because this behavior is common between multiple vendors and the
scancode is currently unused map 0x6e to keycode 193 (KEY_F23) so that
key sequence is generated properly.
MS documentation for the scan code:
https://learn.microsoft.com/en-us/windows/win32/inputdev/about-keyboard-input#scan-codes
Confirmed on Lenovo, HP and Dell machines by Canonical.

commit 19d340a2988d4f3e673cded9dde405d727d7e248 upstream.
When IORING_REGISTER_CLONE_BUFFERS is used to clone buffers from uring
instance A to uring instance B, where A and B use different MMs for
accounting, the accounting can go wrong:
If uring instance A is closed before uring instance B, the pinned memory
counters for uring instance B will be decremented, even though the pinned
memory was originally accounted through uring instance A; so the MM of
uring instance B can end up with negative locked memory.

commit 88006b8eca63467cf1b28fed839f4954c578eeff upstream.
If an LED has a default_trigger set prior to being registered with
the subsystem, that trigger will be executed with a brightness value
defined by `trigger->brightness`. Our driver was not setting this
value, which was causing problems. It would cause the selected LED
to be turned off, as well as corrupt the hlv/llv values assigned to
other LEDs (since calling `wacom_led_brightness_set` will overite
these values).
This patch sets the value of `trigger->brightness` to an appropriate
value. We use `wacom_leds_brightness_get` to transform the llv/hlv
values into a brightness that is understood by the rest of the LED
subsystem.
Fixes: 822c91e72eac ("leds: trigger: Store brightness set by led_trigger_event()")

commit 575a5adf48b06a2980c9eeffedf699ed5534fade upstream.
This patch addresses a null-ptr-deref in qt2_process_read_urb() due to
an incorrect bounds check in the following:
if (newport > serial->num_ports) {
dev_err(&port->dev,
"%s - port change to invalid port: %i\n",
__func__, newport);
break;
}
The condition doesn't account for the valid range of the serial->port
buffer, which is from 0 to serial->num_ports - 1. When newport is equal
to serial->num_ports, the assignment of "port" in the
following code is out-of-bounds and NULL:
serial_priv->current_port = newport;
port = serial->port[serial_priv->current_port];
The fix checks if newport is greater than or equal to serial->num_ports
indicating it is out-of-bounds.

commit 5f537664e705b0bf8b7e329861f20128534f6a83 upstream.
When the 'cachestat()' system call was added in commit cf264e1329fb
("cachestat: implement cachestat syscall"), it was meant to be a much
more convenient (and performant) version of mincore() that didn't need
mapping things into the user virtual address space in order to work.
But it ended up missing the "check for writability or ownership" fix for
mincore(), done in commit 134fca9063ad ("mm/mincore.c: make mincore()
more conservative").
This just adds equivalent logic to 'cachestat()', modified for the file
context (rather than vma).

commit 3d88ba86ba6f35a0467f25a88c38aa5639190d04 upstream.
This reverts commit 251efae73bd46b097deec4f9986d926813aed744.
Quoting Wang Yuli:
"The 27C6:01E0 touchpad doesn't require the workaround and applying it
would actually break functionality.
The initial report came from a BBS forum, but we suspect the
information provided by the forum user may be incorrect which could
happen sometimes. [1]
Further investigation showed that the Lenovo Y9000P 2024 doesn't even
use a Goodix touchpad. [2]
For the broader issue of 27c6:01e0 being unusable on some devices, it
just need to address it with a libinput quirk.
In conclusion, we should revert this commit, which is the best
solution."

commit b9b588f22a0c049a14885399e27625635ae6ef91 upstream.
The mtree mechanism has been effective at creating directory offsets
that are stable over multiple opendir instances. However, it has not
been able to handle the subtleties of renames that are concurrent
with readdir.
Instead of using the mtree to emit entries in the order of their
offset values, use it only to map incoming ctx->pos to a starting
entry. Then use the directory's d_children list, which is already
maintained properly by the dcache, to find the next child to emit.
One of the sneaky things about this is that when the mtree-allocated
offset value wraps (which is very rare), looking up ctx->pos++ is
not going to find the next entry; it will return NULL. Instead, by
following the d_children list, the offset values can appear in any
order but all of the entries in the directory will be visited
eventually.
Note also that the readdir() is guaranteed to reach the tail of this
list. Entries are added only at the head of d_children, and readdir
walks from its current position in that list towards its tail.

commit 68a3a65003145644efcbb651e91db249ccd96281 upstream.
According to getdents(3), the d_off field in each returned directory
entry points to the next entry in the directory. The d_off field in
the last returned entry in the readdir buffer must contain a valid
offset value, but if it points to an actual directory entry, then
readdir/getdents can loop.
This patch introduces a specific fixed offset value that is placed
in the d_off field of the last entry in a directory. Some user space
applications assume that the EOD offset value is larger than the
offsets of real directory entries, so the largest valid offset value
is reserved for this purpose. This new value is never allocated by
simple_offset_add().
When ->iterate_dir() returns, getdents{64} inserts the ctx->pos
value into the d_off field of the last valid entry in the readdir
buffer. When it hits EOD, offset_readdir() sets ctx->pos to the EOD
offset value so the last entry is updated to point to the EOD marker.
When trying to read the entry at the EOD offset, offset_readdir()
terminates immediately.
It is worth noting that using a Maple tree for directory offset
value allocation does not guarantee a 63-bit range of values --
on platforms where "long" is a 32-bit type, the directory offset
value range is still 0..(2^31 - 1). For broad compatibility with
32-bit user space, the largest tmpfs directory cookie value is now
S32_MAX.

commit b662d858131da9a8a14e68661656989b14dbf113 upstream.
The current directory offset allocator (based on mtree_alloc_cyclic)
stores the next offset value to return in octx->next_offset. This
mechanism typically returns values that increase monotonically over
time. Eventually, though, the newly allocated offset value wraps
back to a low number (say, 2) which is smaller than other already-
allocated offset values.
Yu Kuai <yukuai3@huawei.com> reports that, after commit 64a7ce76fb90
("libfs: fix infinite directory reads for offset dir"), if a
directory's offset allocator wraps, existing entries are no longer
visible via readdir/getdents because offset_readdir() stops listing
entries once an entry's offset is larger than octx->next_offset.
These entries vanish persistently -- they can be looked up, but will
never again appear in readdir(3) output.
The reason for this is that the commit treats directory offsets as
monotonically increasing integer values rather than opaque cookies,
and introduces this comparison:
if (dentry2offset(dentry) >= last_index) {
On 64-bit platforms, the directory offset value upper bound is
2^63 - 1. Directory offsets will monotonically increase for millions
of years without wrapping.
On 32-bit platforms, however, LONG_MAX is 2^31 - 1. The allocator
can wrap after only a few weeks (at worst).
Revert commit 64a7ce76fb90 ("libfs: fix infinite directory reads for
offset dir") to prepare for a fix that can work properly on 32-bit
systems and might apply to recent LTS kernels where shmem employs
the simple_offset mechanism.

commit d7bde4f27ceef3dc6d72010a20d4da23db835a32 upstream.
simple_empty() and simple_offset_empty() perform the same task.
The latter's use as a canary to find bugs has not found any new
issues. A subsequent patch will remove the use of the mtree for
iterating directory contents, so revert back to using a similar
mechanism for determining whether a directory is indeed empty.
Only one such mechanism is ever needed.

commit 903dc9c43a155e0893280c7472d4a9a3a83d75a6 upstream.
Testing shows that the EBUSY error return from mtree_alloc_cyclic()
leaks into user space. The ERRORS section of "man creat(2)" says:
> EBUSY O_EXCL was specified in flags and pathname refers
> to a block device that is in use by the system
> (e.g., it is mounted).
ENOSPC is closer to what applications expect in this situation.
Note that the normal range of simple directory offset values is
2..2^63, so hitting this error is going to be rare to impossible.

Pull tracing fix from Steven Rostedt:
"Fix regression in GFP output in trace events
It was reported that the GFP flags in trace events went from human
readable to just their hex values:
gfp_flags=GFP_HIGHUSER_MOVABLE|__GFP_COMP to gfp_flags=0x140cca
This was caused by a change that added the use of enums in calculating
the GFP flags.
As defines get translated into their values in the trace event format
files, the user space tooling could easily convert the GFP flags into
their symbols via the __print_flags() helper macro.
The problem is that enums do not get converted, and the names of the
enums show up in the format files and user space tooling cannot
translate them.
Add TRACE_DEFINE_ENUM() around the enums used for GFP flags which is
the tracing infrastructure macro that informs the tracing subsystem
what the values for enums and it can then expose that to user space"

Tracing tools like perf and trace-cmd read the /sys/kernel/tracing/events/*/*/format
files to know how to parse the data and also how to print it. For the
"print fmt" portion of that file, if anything uses an enum that is not
exported to the tracing system, user space will not be able to parse it.
The GFP flags use to be defines, and defines get translated in the print
fmt sections. But now they are converted to use enums, which is not.
The mm_page_alloc trace event format use to have:
print fmt: "page=%p pfn=0x%lx order=%d migratetype=%d gfp_flags=%s",
REC->pfn != -1UL ? (((struct page *)vmemmap_base) + (REC->pfn)) : ((void

Where the GFP values are shown and not their names. But after the GFP
flags were converted to use enums, it has:
print fmt: "page=%p pfn=0x%lx order=%d migratetype=%d gfp_flags=%s",
REC->pfn != -1UL ? (vmemmap + (REC->pfn)) : ((void *)0), REC->pfn != -1UL
? REC->pfn : 0, REC->order, REC->migratetype, (REC->gfp_flags) ?
__print_flags(REC->gfp_flags, "|", {( unsigned long)((((((((
gfp_t)(((((1UL))) << (___GFP_DIRECT_RECLAIM_BIT))|((((1UL))) <<
(___GFP_KSWAPD_RECLAIM_BIT)))) | (( gfp_t)((((1UL))) << (___GFP_IO_BIT)))
| (( gfp_t)((((1UL))) << (___GFP_FS_BIT))) | (( gfp_t)((((1UL))) <<
(___GFP_HARDWALL_BIT)))) | (( gfp_t)((((1UL))) << (___GFP_HIGHMEM_BIT))))
| (( gfp_t)((((1UL))) << (___GFP_MOVABLE_BIT))) | (( gfp_t)0)) | ((
gfp_t)((((1UL))) << (___GFP_COMP_BIT))) ...
Where the enums names like ___GFP_KSWAPD_RECLAIM_BIT are shown and not their
values. User space has no way to convert these names to their values and
the output will fail to parse. What is shown is now:
mm_page_alloc: page=0xffffffff981685f3 pfn=0x1d1ac1 order=0 migratetype=1 gfp_flags=0x140cca
The TRACE_DEFINE_ENUM() macro was created to handle enums in the print fmt
files. This causes them to be replaced at boot up with the numbers, so
that user space tooling can parse it. By using this macro, the output is
back to the human readable:
mm_page_alloc: page=0xffffffff981685f3 pfn=0x122233 order=0 migratetype=1 gfp_flags=GFP_HIGHUSER_MOVABLE|__GFP_COMP

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing fixes from Steven Rostedt:
- Fix a regression in the irqsoff and wakeup latency tracing
The function graph tracer infrastructure has become generic so that
fprobes and BPF can be based on it. As it use to only handle function
graph tracing, it would always calculate the time the function
entered so that it could then calculate the time it exits and give
the length of time the function executed for. But this is not needed
for the other users (fprobes and BPF) and reading the clock adds a
non-negligible overhead, so the calculation was moved into the
function graph tracer logic.
But the irqsoff and wakeup latency tracers, when the "display-graph"
option was set, would use the function graph tracer to calculate the
times of functions during the latency. The movement of the calltime
calculation made the value zero for these tracers, and the output no
longer showed the length of time of each tracer, but instead the
absolute timestamp of when the function returned (rettime - calltime
where calltime is now zero).
Have the irqsoff and wakeup latency tracers also do the calltime
calculation as the function graph tracer does and report the proper
length of the function timings.
- Update the tracing display to reflect the new preempt lazy model
When the system is configured with preempt lazy, the output of the
trace data would state "unknown" for the current preemption model.
Because the lazy preemption model was just added, make it known to
the tracing subsystem too. This is just a one line change.
- Document multiple function graph having slightly different timings
Now that function graph tracer infrastructure is separate, this also
allows the function graph tracer to run in multiple instances (it
wasn't able to do so before). If two instances ran the function graph
tracer and traced the same functions, the timings for them will be
slightly different because each does their own timings and collects
the timestamps differently. Document this to not have people be
confused by it.
