Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:
Now that the full class driver is in place we can add support to the
Intel machine driver for Cirrus's new SDCA audio CODEC the cs42l45. This
makes some minor tweaks to the machine driver itself to support SDCA
devices, and then adds the necessary tables etc. to define the device.
Note, this series shouldn't have any dependencies on the other series of
improvements to the class driver that is already on the list. So either
can be merged first.
Add support for the Cirrus Logic CS42L45 standalone using SoundWire.

Currently the sof_sdw machine driver assumes that all devices involved
in the sound card are connected through a DAI link. However for SDCA
devices we still want the HID (Human Interface Device, used for jack
buttons) to be part of the sound card, but it contains no DAI links.
Add support into the machine driver to specify a list of auxiliary
devices to merged into the card.

The assumption so far is that all the DAI links for a given audio part
would be on the same device. However, as SDCA implements each audio
function on a separate auxiliary driver this will no longer be true.
This means it is necessary to add additional codec_conf structures to
get the prefix for an audio part to apply to all the auxiliary drivers
that make up that part.

There have been some complaints around the UCM files for SDCA
devices that the control system is quite hard to follow. This is
definitely true without the specification handy the naming can be
a little cryptic. However, as most of the information is parsed
from DisCo there are some limits to what the driver can safely do
to improve this.
However, one area that can be improved is the non-streaming
input/output terminals. These have a field (enum sdca_terminal_type)
that describes the usage of that terminal. These types can be
appended to the entity name to give the users a better clue as
to the purpose. For example "OT 43", would now become "OT 43
Headphone". This would follow through into the jack controls which
would change from "OT 43 Jack" to "OT 43 Headphone Jack", making the
purpose much more obvious to the user.
This provides slightly more readable controls without relying on
implicit knowledge that individual parts might not conform to.

Currently mute controls will be called "FU xx Mute Switch" (note
the switch is added programmatically outside the coverage of this
patch) and the accompanying volume control would be called "FU xx
Channel Volume". These names are taken from the SDCA specification,
however, this does not mesh well with the ALSA naming system. ALSA
generally expects enables rather than mutes and expects that mutes
and volumes have matching names.
Update the names and invert the mute controls to make them more
standard "FU XX Channel Switch", this does slightly deviate from
the SDCA specification but it makes the rest of the Linux ecosystem
a lot happier.

Use kvzalloc() instead of kzalloc() to allocate memory to cache the
content of a firmware control.
Most firmware controls are only small, typically a few bytes. But on
some firmware there can be much larger controls for coefficient or
model data.
The overhead of kvzalloc() is negligible because most control allocs
can be satisfied by the normal kmalloc() that kvzalloc() will try first.

In cs_dsp_debugfs_read_controls_show() take the pwr_lock mutex
around the list walk. This protects against debugfs returning
a partial set of new controls if those controls are being added
to the list while it is being walked.
Controls are never deleted from this list, and are only added to
the end of the list. So there was never a danger of following a
stale pointer to garbage.
The worst case was that the printed list is truncated if it saw an
entry that was the list end just before a new entry was appended to
the list.
With the original code, the truncated list from the debugfs could
show only _some_ of the new entries. This could be confusing because
it appears that some new entries are missing.
Adding the mutex means that the debugfs read provides an atomic view.
Either it shows the old content before any of the new controls were
added; or it shows the new content after all the new controls are
added.

Now that cs_dsp uses regmap_raw_write() instead of regmap_raw_write_async()
it doesn't need to keep multiple DMA-safe buffers of every chunk of data
it wrote.
See commit fe08b7d508 ("firmware: cs_dsp: Remove async regmap writes")
Only one write can be in progress at a time, so one DMA-safe buffer can be
re-used. The single DMA-safe buffer is reallocated if the next write chunk
is larger. Reallocation size is rounded up to reduce the amount of churn.
PAGE_SIZE is used as a convenient size multiple. Typically for .wmfw files
the first chunk is the largest.
A DMA-safe intermediate buffer is used because we can't assume that the
bus underlying regmap can accept non-DMA-safe buffers.
Note that a chunk from the firmware file cannot simply be split into
arbitrarily-sized chunks to avoid buffer reallocation. The data in the
firmware file is preformatted to be written directly to the device as one
block. It already takes account of alignment, write-bursts and write
length requirements of the target hardware, so that the cs_dsp driver can
treat it as an opaque blob.

This also avoids a potential use-after-free in case the DAI is ever

timers: Fix NULL function pointer race in timer_shutdown_sync()
timekeeping: Fix resource leak in tk_aux_sysfs_init() error paths
tick/sched: Fix bogus condition in report_idle_softirq()
There is a race condition between timer_shutdown_sync() and timer
expiration that can lead to hitting a WARN_ON in expire_timers().
The issue occurs when timer_shutdown_sync() clears the timer function
to NULL while the timer is still running on another CPU. The race
scenario looks like this:
CPU0 CPU1
<SOFTIRQ>
lock_timer_base()
expire_timers()
base->running_timer = timer;
unlock_timer_base()
[call_timer_fn enter]
mod_timer()
...
timer_shutdown_sync()
lock_timer_base()
// For now, will not detach the timer but only clear its function to NULL
if (base->running_timer != timer)
ret = detach_if_pending(timer, base, true);
if (shutdown)
timer->function = NULL;
unlock_timer_base()
[call_timer_fn exit]
lock_timer_base()
base->running_timer = NULL;
unlock_timer_base()
...
// Now timer is pending while its function set to NULL.
// next timer trigger
<SOFTIRQ>
expire_timers()
WARN_ON_ONCE(!fn) // hit
...
lock_timer_base()
// Now timer will detach
if (base->running_timer != timer)
ret = detach_if_pending(timer, base, true);
if (shutdown)
timer->function = NULL;
unlock_timer_base()
The problem is that timer_shutdown_sync() clears the timer function
regardless of whether the timer is currently running. This can leave a
pending timer with a NULL function pointer, which triggers the
WARN_ON_ONCE(!fn) check in expire_timers().
Fix this by only clearing the timer function when actually detaching the
timer. If the timer is running, leave the function pointer intact, which is
safe because the timer will be properly detached when it finishes running.

Merge tag 'selinux-pr-20251121' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux
Pull selinux fixes from Paul Moore:
"Three SELinux patches for v6.18 to fix issues around accessing the
per-task decision cache that we introduced in v6.16 to help reduce
SELinux overhead on path walks. The problem was that despite the cache
being located in the SELinux "task_security_struct", the parent struct
wasn't actually tied to the task, it was tied to a cred.
Historically SELinux did locate the task_security_struct in the
task_struct's security blob, but it was later relocated to the cred
struct when the cred work happened, as it made the most sense at the
time.
Unfortunately we never did the task_security_struct to
cred_security_struct rename work (avoid code churn maybe? who knows)
because it didn't really matter at the time. However, it suddenly
became a problem when we added a per-task cache to a per-cred object
and didn't notice because of the old, no-longer-correct struct naming.
Thanks to KCSAN for flagging this, as the silly humans running things
forgot that the task_security_struct was a big lie.
This contains three patches, only one of which actually fixes the
problem described above and moves the SELinux decision cache from the
per-cred struct to a newly (re)created per-task struct.
The other two patches, which form the bulk of the diffstat, take care
of the associated renaming tasks so we can hopefully avoid making the
same stupid mistake in the future.
For the record, I did contemplate sending just a fix for the cache,
leaving the renaming patches for the upcoming merge window, but the
type/variable naming ended up being pretty awful and would have made
v6.18 an outlier stuck between the "old" names and the "new" names in
v6.19. The renaming patches are also fairly mechanical/trivial and
shouldn't pose much risk despite their size.
TLDR; naming things may be hard, but if you mess it up bad things
happen"

Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>:
The CAL_SET_STATUS and CAL_DATA_RB controls are volatile and read-only, but
the existing ASoC macros to define controls don't allow setting access
permissions, so those controls were marked as non-volatile read/write.
These four patches fix that.
The first two patches add two new control macros to soc.h. I really don't
like codec drivers open-coding a kcontrol_new content for a control that
will be managed by the ASoC info/get/put handlers. If a new type of ASoC
control definition is needed it's better to have it in soc.h so all the
dependencies between ASoC and the kcontrol_new content are in one place.
Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:
This series adds an initial SDCA class driver, this consists of a
primary driver attached to the SoundWire device, and auxiliary drivers
representing each of the functions of the SDCA device. These drivers all
use the APIs added over the past series's to provide the class
functionality, as such these final drivers themselves are quite thin.
Also a few fix ups at the start of the series that have gathered up
whilst the last SDCA series was in review.
