With TLS enabled, records that are encrypted and appended to TLS TX
list can fail to see a retry if the underlying TCP socket is busy, for
example, hitting an EAGAIN from tcp_sendmsg_locked(). This is not known
to the NVMe TCP driver, as the TLS layer successfully generated a record.
Typically, the TLS write_space() callback would ensure such records are
retried, but in the NVMe TCP Host driver, write_space() invokes
nvme_tcp_write_space(). This causes a partially sent record in the TLS TX
list to timeout after not being retried.
This patch fixes the above by calling queue->write_space(), which calls
into the TLS layer to retry any pending records.

ASoC: Fixes for v6.18
A moderately large collection of driver specific fixes, plus a few new
quirks and device IDs. The NAU8821 changes are a little large but more
in mechanical ways than in ways that are complex.
When __lookup_instance() allocates a func_instance structure but fails
to allocate the must_write_set array, it returns an error without freeing
the previously allocated func_instance. This causes a memory leak of 192
bytes (sizeof(struct func_instance)) each time this error path is triggered.
Fix by freeing 'result' on must_write_set allocation failure.

The new drm_*() logging functions take a struct drm_device * as the

the specific DRM device name and instance, which is essential for
distinguishing logs when multiple GPUs or display controllers are present.

one time from skb_consume_udp(), then a second time from skb_defer_free_flush()
and napi_consume_skb().
As Sabrina suggested, remove skb_release_head_state() call from

If obj_exts allocation failed, slab->obj_exts is set to OBJEXTS_ALLOC_FAIL,
But we do not clear it when freeing the slab. Since OBJEXTS_ALLOC_FAIL and
MEMCG_DATA_OBJEXTS currently share the same bit position, during the
release of the associated folio, a VM_BUG_ON_FOLIO() check in
folio_memcg_kmem() is triggered because the OBJEXTS_ALLOC_FAIL flag was
not cleared, causing it to be interpreted as a kmem folio (non-slab)
with MEMCG_OBJEXTS_DATA flag set, which is invalid because
MEMCG_OBJEXTS_DATA is supposed to be set only on slabs.
Another problem that predates sharing the OBJEXTS_ALLOC_FAIL and
MEMCG_DATA_OBJEXTS bits is that on configurations with
is_check_pages_enabled(), the non-cleared bit in page->memcg_data will
trigger a free_page_is_bad() failure "page still charged to cgroup"
When freeing a slab, we clear slab->obj_exts if the obj_ext array has
been successfully allocated. So let's clear it also when the allocation
has failed.

When adding dependencies with drm_sched_job_add_dependency(), that
function consumes the fence reference both on success and failure, so in
the latter case the dma_fence_put() on the error path (xarray failed to
expand) is a double free.
Interestingly this bug appears to have been present ever since
commit ebd5f74255 ("drm/sched: Add dependency tracking"), since the code
back then looked like this:
drm_sched_job_add_implicit_dependencies():
...
for (i = 0; i < fence_count; i++) {
ret = drm_sched_job_add_dependency(job, fences[i]);
if (ret)
break;
}
for (; i < fence_count; i++)
dma_fence_put(fences[i]);
Which means for the failing 'i' the dma_fence_put was already a double
free. Possibly there were no users at that time, or the test cases were
insufficient to hit it.
The bug was then only noticed and fixed after
commit 9c2ba26535 ("drm/scheduler: use new iterator in drm_sched_job_add_implicit_dependencies v2")
landed, with its fixup of
commit 4eaf02d607 ("drm/scheduler: fix drm_sched_job_add_implicit_dependencies").
At that point it was a slightly different flavour of a double free, which
commit 963d0b3569 ("drm/scheduler: fix drm_sched_job_add_implicit_dependencies harder")
noticed and attempted to fix.
But it only moved the double free from happening inside the
drm_sched_job_add_dependency(), when releasing the reference not yet
obtained, to the caller, when releasing the reference already released by
the former in the failure case.
As such it is not easy to identify the right target for the fixes tag so
lets keep it simple and just continue the chain.
While fixing we also improve the comment and explain the reason for taking
the reference and not dropping it.

Merge series from Cristian Ciocaltea <cristian.ciocaltea@collabora.com>:
This patch series addresses a set of issues in the Nuvoton NAU88L21
audio codec driver related to interrupt handling and jack hotplug
detection reliability.
The changes focus on:
* Eliminating race conditions between jack insertion and ejection events
* Ensuring interrupts are consistently and correctly cleared before
unmasking
* Introducing a DMI-based quirk to bypass the jack debounce circuit on
Valve Steam Deck, improving detection accuracy under stress
* Improving robustness of the IRQ handler by avoiding unnecessary
blocking operations
The series has been tested on affected hardware to verify correct
behavior during repeated and rapid jack hotplug cycles.

If the location madvise() is set to
DRM_XE_PREFERRED_LOC_DEFAULT_SYSTEM, the drm_pagemap in the
SVM gpu fault handler will be set to NULL. However there is nothing
that explicitly migrates the data to system if it is already present
in device memory.
In that case, set the device memory owner to NULL to ensure
data gets properly migrated to system on page-fault.

With async crypto, we rely on tx_work to actually transmit records
once encryption completes. But while send() is running, both the
tx_lock and socket lock are held, so tx_work_handler cannot process
the queue of encrypted records, and simply reschedules itself. During
a large send(), this could last a long time, and use a lot of memory.
Transmit any pending encrypted records before restarting the main
loop of tls_sw_sendmsg_locked.

Async decryption calls tls_strp_msg_hold to create a clone of the
input skb to hold references to the memory it uses. If we fail to
allocate that clone, proceeding with async decryption can lead to
various issues (UAF on the skb, writing into userspace memory after
the recv() call has returned).
In this case, wait for all pending decryption requests.

When userspace wants to send a non-DATA record (via the
TLS_SET_RECORD_TYPE cmsg), we need to send any pending data from a
previous MSG_MORE send() as a separate DATA record. If that DATA record
is encrypted asynchronously, tls_handle_open_record will return
-EINPROGRESS. This is currently treated as an error by
tls_process_cmsg, and it will skip setting record_type to the correct
value, but the caller (tls_sw_sendmsg_locked) handles that return
value correctly and proceeds with sending the new message with an
incorrect record_type (DATA instead of whatever was requested in the
cmsg).
Always set record_type before handling the open record. If
tls_handle_open_record returns an error, record_type will be
ignored. If it succeeds, whether with synchronous crypto (returning 0)
or asynchronous (returning -EINPROGRESS), the caller will proceed
correctly.

If we hit an error during the main loop of tls_sw_sendmsg_locked (eg
failed allocation), we jump to send_end and immediately
return. Previous iterations may have queued async encryption requests
that are still pending. We should wait for those before returning, as
we could otherwise be reading from memory that userspace believes
we're not using anymore, which would be a sort of use-after-free.
This is similar to what tls_sw_recvmsg already does: failures during
the main loop jump to the "wait for async" code, not straight to the
unlock/return.

During tls_sw_sendmsg_locked, we pre-allocate the encrypted message
for the size we're expecting to send during the current iteration, but
we may end up sending less, for example when splicing: if we're
getting the data from small fragments of memory, we may fill up all
the slots in the skmsg with less data than expected.
In this case, we need to trim the encrypted message to only the length
we actually need, to avoid pushing uninitialized bytes down the
underlying TCP socket.
