ASoC: cs35l56: Log a message if firmware is missing
If the amp is still reporting FIRMWARE_MISSING after cs35l56_patch()
has completed it is helpful to log a warning.
After a complete firmware download the FIRMWARE_MISSING flag will be
clear. If this isn't the case, the driver should log a message to
report this.
The amp can produce basic audio output without firmware, as a fallback,
so this wasn't originally logged as a warning condition because the amp
is still in an operational state - just not with full functionality.
However, it was not at all obvious to an end user that anything is
unusual.
firmware: cs_dsp: Add test cases for client_ops == NULL
Add test cases for the client not providing a pointer to a
struct cs_dsp_client_ops. This proves that it is safe for the client
to leave the client_ops pointer at NULL if it does not need to
implement any of the callbacks.
firmware: cs_dsp: Don't require client to provide a struct cs_dsp_client_ops
A client of cs_dsp does not necessarily need to implement any of the
optional callbacks in struct cs_dsp_client_ops, so allow the client_ops
pointer to be NULL.
This has been done by pointing client_ops at a default empty
cs_dsp_client_ops. It keeps the code cleaner by avoiding having to add
double nested NULL checks everywhere one of these callbacks is called.

a lot happier.
firmware: cs_dsp: Take pwr_lock around reading controls debugfs
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.

Smatch complains that the call to snd_soc_component_get_drvdata(component)

function will never be called with a NULL component pointer so just
delete the check.
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 fe08b7d5085a ("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.

timers: Fix NULL function pointer race in timer_shutdown_sync()
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.

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

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

For the record, I did contemplate sending just a fix for the cache,
leaving the renaming patches for the upcoming merge window, but the

samples: work around glibc redefining some of our defines wrong
Apparently as of version 2.42, glibc headers define AT_RENAME_NOREPLACE
and some of the other flags for renameat2() and friends in <stdio.h>.
Which would all be fine, except for inexplicable reasons glibc decided
to define them _differently_ from the kernel definitions, which then
makes some of our sample code that includes both kernel headers and user
space headers unhappy, because the compiler will (correctly) complain
about redefining things.
Now, mixing kernel headers and user space headers is always a somewhat
iffy proposition due to namespacing issues, but it's kind of inevitable
in our sample and selftest code. And this is just glibc being stupid.
Those defines come from the kernel, glibc is exposing the kernel
interfaces, and glibc shouldn't make up some random new expressions for
these values.
It's not like glibc headers changed the actual result values, but they
arbitrarily just decided to use a different expression to describe those
values. The kernel just does
instead. Same value in the end, but very different macro definition.
For absolutely no reason.
This has since been fixed in the glibc development tree, so eventually
we'll end up with the canonical expressions and no clashes. But in the
meantime the broken headers are in the glibc-2.42 release and have made
it out into distributions.
Do a minimal work-around to make the samples build cleanly by just
undefining the affected macros in between the user space header include
and the kernel header includes.
ASoC: Intel: avs: Replace snprintf() with scnprintf()
snprintf() as defined by the C99 standard,returns the
number of characters that *would have been* written if
enough space were available.Use scnprintf() that returns
the actual number of characters written.
Commit 69896119dc9d ("MIPS: vdso: Switch to generic storage
implementation") switches to a generic vdso storage, which increases
the number of data pages from 1 to 4. But there is only one page
reserved, which causes segementation faults depending where the VDSO
area is randomized to. To fix this use the same size of reservation
and allocation of the VDSO data pages.

MIPS: mm: Prevent a TLB shutdown on initial uniquification
Depending on the particular CPU implementation a TLB shutdown may occur
if multiple matching entries are detected upon the execution of a TLBP
or the TLBWI/TLBWR instructions. Given that we don't know what entries
we have been handed we need to be very careful with the initial TLB
setup and avoid all these instructions.
Therefore read all the TLB entries one by one with the TLBR instruction,
bypassing the content addressing logic, and truncate any large pages in
place so as to avoid a case in the second step where an incoming entry
for a large page at a lower address overlaps with a replacement entry
chosen at another index. Then preinitialize the TLB using addresses
outside our usual unique range and avoiding clashes with any entries
received, before making the usual call to local_flush_tlb_all().
This fixes (at least) R4x00 cores if TLBP hits multiple matching TLB
entries (SGI IP22 PROM for examples sets up all TLBs to the same virtual
address).

- openvswitch: remove never-working support for setting NSH fields
- xfrm: number of fixes for error paths of xfrm_state creation/
modification/deletion
- xfrm: fixes for offload
- fix the determination of the protocol of the inner packet
- don't push locally generated packets directly to L2 tunnel

firmware: cs_dsp: Cleanup debugfs for wmfw and bin
Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>:
These two patches improve the implementation of the debugfs files for
the wmfw and bin file names. First patch removes duplicated code. Second
patch replaces the old clunkiness of storing the filename with an appended
\n. The \n can be appended when the file is read, to keep the stored string
sane.
ASoC: cs35l56: Use SND_SOC_BYTES_E_ACC() for CAL_DATA_RB control
Use the new SND_SOC_BYTES_E_ACC() macro instead of SND_SOC_BYTES_E()
to define the CAL_DATA_RB control, so that it is marked as read-only
and volatile.
This avoids userland code expecting to be able to write to it and
then getting an unexpected EPERM error, or assuming that its value
can never change.
