sound fixes for 6.13-rc3
Likely the last PR in 2025, again a collection of lots of small fixes.
Most of them are various device-specific small fixes.
* An ASoC core fix for correcting the clamping behavior of *_SX mixer
elements
* Various fixes for ASoC fsl, SOF, etc
* Usual HD- and USB-audio quirks / fix-ups
* A couple of error-handling fixes for legacy PCMCIA drivers

clang: work around asm output constraint problems
Work around clang problems with "=rm" asm constraint. clang seems to always chose the memory output, while it is almost always the worst choice. Add ASM_OUTPUT_RM so that we can replace "=rm" constraint where it matters for clang, while not penalizing gcc.

drm/xe: Limit num_syncs to prevent oversized allocations
The exec and vm_bind ioctl allow userspace to specify an arbitrary num_syncs value. Without bounds checking, a very large num_syncs can force an excessively large allocation, leading to kernel warnings from the page allocator as below. Introduce DRM_XE_MAX_SYNCS (set to 1024) and reject any request exceeding this limit.

Fix this issue in the same way as rapl powercap package domain is added
from the same CPU online callback by introducing another interface which
doesn't call cpus_read_lock(). Add rapl_package_add_pmu_locked() and
rapl_package_remove_pmu_locked() which don't call cpus_read_lock().

block: add allocation size check in blkdev_pr_read_keys()
blkdev_pr_read_keys() takes num_keys from userspace and uses it to
calculate the allocation size for keys_info via struct_size(). While
there is a check for SIZE_MAX (integer overflow), there is no upper
bound validation on the allocation size itself.
A malicious or buggy userspace can pass a large num_keys value that
doesn't trigger overflow but still results in an excessive allocation
attempt, causing a warning in the page allocator when the order exceeds
MAX_PAGE_ORDER.
Fix this by introducing PR_KEYS_MAX to limit the number of keys to
a sane value. This makes the SIZE_MAX check redundant, so remove it.
Also switch to kvzalloc/kvfree to handle larger allocations gracefully.

shmem: fix recovery on rename failures
maple_tree insertions can fail if we are seriously short on memory;
simple_offset_rename() does not recover well if it runs into that.
The same goes for simple_offset_rename_exchange().
Moreover, shmem_whiteout() expects that if it succeeds, the caller will
progress to d_move(), i.e. that shmem_rename2() won't fail past the
successful call of shmem_whiteout().
Not hard to fix, fortunately - mtree_store() can't fail if the index we
are trying to store into is already present in the tree as a singleton.
For simple_offset_rename_exchange() that's enough - we just need to be
careful about the order of operations.
For simple_offset_rename() solution is to preinsert the target into the
tree for new_dir; the rest can be done without any potentially failing
operations.
That preinsertion has to be done in shmem_rename2() rather than in
simple_offset_rename() itself - otherwise we'd need to deal with the
possibility of failure after successful shmem_whiteout().

ASoC: soc-acpi / SOF: Add best_effort flag to get_function_tplg_files op
When there is no fallback possibility available for the function topology use it is better to try to create a profile for the card in best effort manner, leaving out non supported links for example. As an example: some laptops present SSPx-BT link but we don't have fragment yet to support this. If we only have support for functional topology without monolithic fallback then we would fail the card creation. The reason why the monolithic topology works on the same device is that it does not have the SSPx-BT link handled, it is ignored. In case when there is no fallback possibility we should try to create the card with links that we support as best effort instead of failing and leaving the user without a card.

netfilter: nf_tables: avoid chain re-validation if possible
Hamza Mahfooz reports cpu soft lock-ups in nft_chain_validate(): watchdog: BUG: soft lockup - CPU#1 stuck for 27s!

But there are cases where we could avoid revalidation. Consider: 1 input -> j2 -> j3 2 input -> j2 -> j3 3 input -> j1 -> j2 -> j3 Then the second rule does not need to revalidate j2, and, by extension j3, because this was already checked during validation of the first rule. We need to validate it only for rule 3. This is needed because chain loop detection also ensures we do not exceed the jump stack: Just because we know that j2 is cycle free, its last jump might now exceed the allowed stack size. We also need to update all reachable chains with the new largest observed call depth. Care has to be taken to revalidate even if the chain depth won't be an issue: chain validation also ensures that expressions are not called from invalid base chains. For example, the masquerade expression can only be called from NAT postrouting base chains. Therefore we also need to keep record of the base chain context (type, hooknum) and revalidate if the chain becomes reachable from a different hook location.

file: ensure cleanup
Brown paper bag time. This is a silly oversight where I missed to drop
the error condition checking to ensure we clean up on early error
returns. I have an internal unit testset coming up for this which will
catch all such issues going forward.

sound fixes for 6.19-rc1
The rest for 6.19 merge window. The only slightly large change is
the enablement of CIX HD-audio controller, which took a bit time to
be cooked up, while most of other changes are device-specific small
trivial fixes.
- Default disablement of the kconfig for decades old pre-release
alsa-lib PCM API; it's only the default config value change, so
it can't lead to any regressions for the existing setups
- Support for CIX HD-audio controller
- A few ASoC ACP fixes
- Fixes for ASoC cirrus, bcm, wcd, qcom, ak platforms
- Trivial hardening for FireWire and USB-audio
- HD-audio Intel binding fix and quirks

ceph: add trace points to the MDS client
This patch adds trace points to the Ceph filesystem MDS client: - request submission (CEPH_MSG_CLIENT_REQUEST) and completion (CEPH_MSG_CLIENT_REPLY) - capabilities (CEPH_MSG_CLIENT_CAPS) These are the central pieces that are useful for analyzing MDS latency/performance problems from the client's perspective. In the long run, all doutc() calls should be replaced with tracepoints. This way, the Ceph filesystem can be traced at any time (without spamming the kernel log). Additionally, trace points can be used in BPF programs (which can even deference the pointer parameters and extract more values).

inet: frags: flush pending skbs in fqdir_pre_exit()
We have been seeing occasional deadlocks on pernet_ops_rwsem since
September in NIPA. The stuck task was usually modprobe (often loading
a driver like ipvlan), trying to take the lock as a Writer.
lockdep does not track readers for rwsems so the read wasn't obvious
from the reports.
On closer inspection the Reader holding the lock was conntrack looping
forever in nf_conntrack_cleanup_net_list(). Based on past experience
with occasional NIPA crashes I looked thru the tests which run before
the crash and noticed that the crash follows ip_defrag.sh. An immediate
red flag. Scouring thru (de)fragmentation queues reveals skbs sitting
around, holding conntrack references.
The problem is that since conntrack depends on nf_defrag_ipv6,
nf_defrag_ipv6 will load first. Since nf_defrag_ipv6 loads first its
netns exit hooks run _after_ conntrack's netns exit hook.
Flush all fragment queue SKBs during fqdir_pre_exit() to release
conntrack references before conntrack cleanup runs. Also flush
the queues in timer expiry handlers when they discover fqdir->dead
is set, in case packet sneaks in while we're running the pre_exit
flush.
The commit under Fixes is not exactly the culprit, but I think
previously the timer firing would eventually unblock the spinning
conntrack.
Fixes:

bpf: Add bpf_has_frame_pointer()
Introduce a bpf_has_frame_pointer() helper that unwinders can call to determine whether a given instruction pointer is within the valid frame pointer region of a BPF JIT program or trampoline (i.e., after the prologue, before the epilogue). This will enable livepatch (with the ORC unwinder) to reliably unwind through BPF JIT frames.

lockref: add a __cond_lock annotation for lockref_put_or_lock
Add a cond_lock annotation for lockref_put_or_lock to make sparse happy with using it. Note that for this the return value has to be double-inverted as the return value convention of lockref_put_or_lock is inverted compared to _trylock conventions expected by __cond_lock, as lockref_put_or_lock returns true when it did not need to take the lock.
