ALSA: pcm: Clear the full allocated memory at hw_params

2021-01-06T13:45:01+00:00

[ Upstream commit 618de0f4ef11acd8cf26902e65493d46cc20cc89 ]

The PCM hw_params core function tries to clear up the PCM buffer
before actually using for avoiding the information leak from the
previous usages or the usage before a new allocation.  It performs the
memset() with runtime->dma_bytes, but this might still leave some
remaining bytes untouched; namely, the PCM buffer size is aligned in
page size for mmap, hence runtime->dma_bytes doesn't necessarily cover
all PCM buffer pages, and the remaining bytes are exposed via mmap.

This patch changes the memory clearance to cover the all buffer pages
if the stream is supposed to be mmap-ready (that guarantees that the
buffer size is aligned in page size).

ALSA: rawmidi: Access runtime->avail always in spinlock

2021-01-06T13:45:00+00:00

commit 88a06d6fd6b369d88cec46c62db3e2604a2f50d5 upstream.

The runtime->avail field may be accessed concurrently while some
places refer to it without taking the runtime->lock spinlock, as
detected by KCSAN.  Usually this isn't a big problem, but for
consistency and safety, we should take the spinlock at each place
referencing this field.

ALSA: seq: Use bool for snd_seq_queue internal flags

2021-01-06T13:45:00+00:00

commit 4ebd47037027c4beae99680bff3b20fdee5d7c1e upstream.

The snd_seq_queue struct contains various flags in the bit fields.
Those are categorized to two different use cases, both of which are
protected by different spinlocks.  That implies that there are still
potential risks of the bad operations for bit fields by concurrent
accesses.

For addressing the problem, this patch rearranges those flags to be
a standard bool instead of a bit field.

ALSA: usb-audio: Disable sample read check if firmware doesn't give back

2020-12-30T10:26:09+00:00

commit 9df28edce7c6ab38050235f6f8b43dd7ccd01b6d upstream.

Some buggy firmware don't give the current sample rate but leaves
zero.  Handle this case more gracefully without warning but just skip
the current rate verification from the next time.

ALSA: hda/realtek: Apply jack fixup for Quanta NL3

2020-12-30T10:26:09+00:00

commit 6ca653e3f73a1af0f30dbf9c2c79d2897074989f upstream.

The Quanta NL3 laptop has both a headphone output jack and a headset
jack, on the right edge of the chassis.

The pin information suggests that both of these are at the Front.
The PulseAudio is confused to differentiate them so one of the jack
can neither get the jack sense working nor the audio output.

The ALC269_FIXUP_LIFEBOOK chained with ALC269_FIXUP_QUANTA_MUTE can
help to differentiate 2 jacks and get the 'Auto-Mute Mode' working
correctly.

ALSA: pcm: oss: Fix a few more UBSAN fixes

2020-12-30T10:26:08+00:00

commit 11cb881bf075cea41092a20236ba708b18e1dbb2 upstream.

There are a few places that call round{up|down}_pow_of_two() with the
value zero, and this causes undefined behavior warnings.  Avoid
calling those macros if such a nonsense value is passed; it's a minor
optimization as well, as we handle it as either an error or a value to
be skipped, instead.
