[ Upstream commit 9b5f8ee43e ]
The SH DAC audio driver uses the kmalloc'ed buffer as the main PCM
buffer, and the data is transferred via hrtimer callbacks manually
from there to the hardware. Meanwhile, some of its code are written
as if the buffer is on iomem and use the special helpers for the iomem
(e.g. copy_from_iter_toio() or memset_io()). Those are rather useless
and the standard helpers should be used.
Similarly, the PCM mmap callback is set to a special one with
snd_pcm_lib_mmap_iomem, but this is also nonsense, because SH
architecture doesn't support this function, hence it leads just to
NULL -- the fallback to the standard helper.
This patch replaces those special setups with the standard ones.

[ Upstream commit 4f9d674377 ]
The low-latency mode of USB-audio driver uses a similar approach like
the implicit feedback mode but it has an explicit queuing at the
trigger start time. The difference is, however, that no packet will
be handled any longer after all queued packets are handled but no
enough data is fed. In the case of implicit feedback mode, the
capture-side packet handling triggers the re-queuing, and this checks
the XRUN. OTOH, in the low-latency mode, it just stops without XRUN
notification unless any new action is taken from user-space via ack
callback. For example, when you stop the stream in aplay, no XRUN is
reported.
This patch adds the XRUN check at the packet complete callback in the
case all pending URBs are exhausted. Strictly speaking, this state
doesn't match really with XRUN; in theory the application may queue
immediately after this happens. But such behavior is only for
1-period configuration, which the USB-audio driver doesn't support.
So we may conclude that this situation leads certainly to XRUN.
A caveat is that the XRUN should be triggered only for the PCM RUNNING
state, and not during DRAINING. This additional state check is put in
notify_xrun(), too.

An atomicity violation occurs when the validity of the variables
da7219->clk_src and da7219->mclk_rate is being assessed. Since the entire
assessment is not protected by a lock, the da7219 variable might still be
in flux during the assessment, rendering this check invalid.
To fix this issue, we recommend adding a lock before the block
if ((da7219->clk_src == clk_id) && (da7219->mclk_rate == freq)) so that
the legitimacy check for da7219->clk_src and da7219->mclk_rate is
protected by the lock, ensuring the validity of the check.
This possible bug is found by an experimental static analysis tool
developed by our team. This tool analyzes the locking APIs
to extract function pairs that can be concurrently executed, and then
analyzes the instructions in the paired functions to identify possible
concurrency bugs including data races and atomicity violations.

The current USB-audio driver code doesn't check bLength of each
descriptor at traversing for clock descriptors. That is, when a
device provides a bogus descriptor with a shorter bLength, the driver
might hit out-of-bounds reads.
For addressing it, this patch adds sanity checks to the validator
functions for the clock descriptor traversal. When the descriptor
length is shorter than expected, it's skipped in the loop.
For the clock source and clock multiplier descriptors, we can just
check bLength against the sizeof() of each descriptor type.
OTOH, the clock selector descriptor of UAC2 and UAC3 has an array
of bNrInPins elements and two more fields at its tail, hence those
have to be checked in addition to the sizeof() check.

[ Upstream commit b04dcbb7f7 ]
The USB disconnect callback is supposed to be short and not too-long
waiting. OTOH, the current code uses snd_card_free() at
disconnection, but this waits for the close of all used fds, hence it
can take long. It eventually blocks the upper layer USB ioctls, which
may trigger a soft lockup.
An easy workaround is to replace snd_card_free() with
snd_card_free_when_closed(). This variant returns immediately while
the release of resources is done asynchronously by the card device
release at the last close.
This patch also splits the code to the disconnect and the free phases;
the former is called immediately at the USB disconnect callback while
the latter is called from the card destructor.

[ Upstream commit b7df09bb34 ]
The USB disconnect callback is supposed to be short and not too-long
waiting. OTOH, the current code uses snd_card_free() at
disconnection, but this waits for the close of all used fds, hence it
can take long. It eventually blocks the upper layer USB ioctls, which
may trigger a soft lockup.
An easy workaround is to replace snd_card_free() with
snd_card_free_when_closed(). This variant returns immediately while
the release of resources is done asynchronously by the card device
release at the last close.
The loop of us122l->mmap_count check is dropped as well. The check is
useless for the asynchronous operation with *_when_closed().

The last parameter 1 means BIT(0), which should be the
correct BIT(X).
