The TUXEDO Sirius 16 Gen1 and the TUXEDO Sirius 16 Gen2 Notebooks have an
additional "fan" key next to F12.
Pressing it alone sends a F14 key press which can be bound by user space.
Pressing it while holding the FN key triggers two things:
- The EC firmware locks the fan speed of the internal fans at 100%
- F13 key press is registered which by default is already bound in xkb and
desktop environments (e.g. in KDE Plasma it launches system settings)
To avoid this unexpected double duty of the FN shortcut, this bpf program
suppresses the F13 key press.

Commit 3775fc538f ("PM: sleep: core: Synchronize runtime PM status of
parents and children") exposed an issue related to simple_pm_bus_pm_ops
that uses pm_runtime_force_suspend() and pm_runtime_force_resume() as
bus type PM callbacks for the noirq phases of system-wide suspend and
resume.
The problem is that pm_runtime_force_suspend() does not distinguish
runtime-suspended devices from devices for which runtime PM has never
been enabled, so if it sees a device with runtime PM status set to
RPM_ACTIVE, it will assume that runtime PM is enabled for that device
and so it will attempt to suspend it with the help of its runtime PM
callbacks which may not be ready for that. As it turns out, this
causes simple_pm_bus_runtime_suspend() to crash due to a NULL pointer
dereference.
Another problem related to the above commit and simple_pm_bus_pm_ops is
that setting runtime PM status of a device handled by the latter to
RPM_ACTIVE will actually prevent it from being resumed because
pm_runtime_force_resume() only resumes devices with runtime PM status
set to RPM_SUSPENDED.
To mitigate these issues, do not allow power.set_active to propagate
beyond the parent of the device with DPM_FLAG_SMART_SUSPEND set that
will need to be resumed, which should be a sufficient stop-gap for the
time being, but they will need to be properly addressed in the future
because in general during system-wide resume it is necessary to resume
all devices in a dependency chain in which at least one device is going
to be resumed.

The code was restructured where the function graph notrace code, that
would not trace a function and all its children is done by setting a
NOTRACE flag when the function that is not to be traced is hit.
There's a TRACE_GRAPH_NOTRACE_BIT which defines the bit in the flags and a
TRACE_GRAPH_NOTRACE which is the mask with that bit set. But the
restructuring used TRACE_GRAPH_NOTRACE_BIT when it should have used
TRACE_GRAPH_NOTRACE.
For example:
# cd /sys/kernel/tracing
# echo set_track_prepare stack_trace_save > set_graph_notrace
# echo function_graph > current_tracer
# cat trace
[..]

0) | free_to_partial_list() {
0) | arch_stack_walk() {

# echo > set_graph_notrace

0) | set_track_prepare() {
0) | stack_trace_save() {
0) | arch_stack_walk() {

Where the filter should look like:

-Wenum-enum-conversion was strengthened in clang-19 to warn for C, which
caused the kernel to move it to W=1 in commit 75b5ab134b ("kbuild:
Move -Wenum-{compare-conditional,enum-conversion} into W=1") because
there were numerous instances that would break builds with -Werror.
Unfortunately, this is not a full solution, as more and more developers,
subsystems, and distributors are building with W=1 as well, so they
continue to see the numerous instances of this warning.
Since the move to W=1, there have not been many new instances that have
appeared through various build reports and the ones that have appeared
seem to be following similar existing patterns, suggesting that most
instances of this warning will not be real issues. The only alternatives
for silencing this warning are adding casts (which is generally seen as
an ugly practice) or refactoring the enums to macro defines or a unified
enum (which may be undesirable because of type safety in other parts of
the code).
Move the warning to W=2, where warnings that occur frequently but may be
relevant should reside.

Pull vfs fixes from Christian Brauner:
- Fix fsnotify FMODE_NONOTIFY* handling.
This also disables fsnotify on all pseudo files by default apart from
very select exceptions. This carries a regression risk so we need to
watch out and adapt accordingly. However, it is overall a significant
improvement over the current status quo where every rando file can
get fsnotify enabled.
- Cleanup and simplify lockref_init() after recent lockref changes.
- Fix vboxfs build with gcc-15.
- Add an assert into inode_set_cached_link() to catch corrupt links.
- Allow users to also use an empty string check to detect whether a
given mount option string was empty or not.
- Fix how security options were appended to statmount()'s ->mnt_opt
field.
- Fix statmount() selftests to always check the returned mask.
- Fix uninitialized value in vfs_statx_path().
- Fix pidfs_ioctl() sanity checks to guard against ioctl() overloading
and preserve extensibility.

I no longer have any faith left in the kernel development process or
community management approach.
Apple/ARM platform development will continue downstream. If I feel like
sending some patches upstream in the future myself for whatever subtree
I may, or I may not. Anyone who feels like fighting the upstreaming
fight themselves is welcome to do so.

Lockdep reported that, as steam_do_deck_input_event is called from
steam_raw_event inside of an IRQ context, it can lead to issues if that IRQ
occurs while the work to be cancelled is running. By using cancel_delayed_work,
this issue can be avoided. The exact ordering of the work and the event
processing is not super important, so this is safe.

Due to an interplay between locking in the input and hid transport subsystems,
attempting to register or deregister the relevant input devices during the
hidraw open/close events can lead to a lock ordering issue. Though this
shouldn't cause a deadlock, this commit moves the input device manipulation to
deferred work to sidestep the issue.

Syzbot[1] has detected a stack-out-of-bounds read of the ep_addr array from
hid-thrustmaster driver. This array is passed to usb_check_int_endpoints
function from usb.c core driver, which executes a for loop that iterates
over the elements of the passed array. Not finding a null element at the end of
the array, it tries to read the next, non-existent element, crashing the kernel.
To fix this, a 0 element was added at the end of the array to break the for
loop.

The Omoton KB066 is an Apple A1255 keyboard clone (HID product code
05ac:022c). On both keyboards, the F6 key becomes Num Lock when the Fn
key is held. But unlike its Apple exemplar, when the Omoton's F6 key is
pressed without Fn, it sends the usage code 0xC0301 from the reserved
section of the consumer page instead of the standard F6 usage code
0x7003F from the keyboard page. The nonstandard code is translated to
KEY_UNKNOWN and becomes useless on Linux. The Omoton KB066 is a pretty
popular keyboard, judging from its 29,058 reviews on Amazon at time of
writing, so let's account for its quirk to make it more usable.
By the way, it would be nice if we could automatically set fnmode to 0
for Omoton keyboards because they handle the Fn key internally and the
kernel's Fn key handling creates undesirable side effects such as making
F1 and F2 always Brightness Up and Brightness Down in fnmode=1 (the
default) or always F1 and F2 in fnmode=2. Unfortunately I don't think
there's a way to identify Bluetooth keyboards more specifically than the
HID product code which is obviously inaccurate. Users of Omoton
keyboards will just have to set fnmode to 0 manually to get full Fn key
functionality.

This costs a strlen() call when instatianating a symlink.
Preferably it would be hidden behind VFS_WARN_ON (or compatible), but
there is no such facility at the moment. With the facility in place the
call can be patched out in production kernels.
In the meantime, since the cost is being paid unconditionally, use the
result to a fixup the bad caller.
This is not expected to persist in the long run (tm).
Sample splat:
bad length passed for symlink [/tmp/syz-imagegen43743633/file0/file0] (got 131109, expected 37)

Pidfs supports extensible and non-extensible ioctls. The extensible
ioctls need to check for the ioctl number itself not just the ioctl
command otherwise both backward- and forward compatibility are broken.
The pidfs ioctl handler also needs to look at the type of the ioctl
command to guard against cases where "[...] a daemon receives some
random file descriptor from a (potentially less privileged) client and
expects the FD to be of some specific type, it might call ioctl() on
this FD with some type-specific command and expect the call to fail if
the FD is of the wrong type; but due to the missing type check, the
kernel instead performs some action that userspace didn't expect."

After introducing pre-content events, we had a regression related to
disabling huge faults on files that should never have pre-content events
enabled.
This happened because the default f_mode of allocated files (0) does
not disable pre-content events.
Pre-content events are disabled in file_set_fsnotify_mode_by_watchers()
but internal files may not get to call this helper.
Initialize f_mode to disable permission and pre-content events for all
files and if needed they will be enabled for the callers of
file_set_fsnotify_mode_by_watchers().

STATMOUNT_MNT_OPTS can actually be missing if there are no options. This
is a change of behavior since 75ead69a71 ("fs: don't let statmount return
empty strings").
The other checks shouldn't actually trigger, but add them for correctness
and for easier debugging if the test fails.
