      ALSA: usb-audio: Apply sample rate quirk to Sennheiser headset · a8e800fe
      由 Takashi Iwai 提交于 
      A Senheisser headset requires the typical sample-rate quirk for
avoiding spurious errors from inquiring the current sample rate like:
 usb 1-1: 2:1: cannot get freq at ep 0x4
 usb 1-1: 3:1: cannot get freq at ep 0x83

The USB ID 1395:740a has to be added to the entries in
snd_usb_get_sample_rate_quirk().

      ALSA: seq: 2nd attempt at fixing race creating a queue · 7e1d90f6
      由 Daniel Mentz 提交于 
      commit 4842e98f ("ALSA: seq: Fix race at
creating a queue") attempted to fix a race reported by syzkaller. That
fix has been described as follows:

"
When a sequencer queue is created in snd_seq_queue_alloc(),it adds the
new queue element to the public list before referencing it.  Thus the
queue might be deleted before the call of snd_seq_queue_use(), and it
results in the use-after-free error, as spotted by syzkaller.

The fix is to reference the queue object at the right time.
"

Even with that fix in place, syzkaller reported a use-after-free error.
It specifically pointed to the last instruction "return q->queue" in
snd_seq_queue_alloc(). The pointer q is being used after kfree() has
been called on it.

It turned out that there is still a small window where a race can
happen. The window opens at
snd_seq_ioctl_create_queue()->snd_seq_queue_alloc()->queue_list_add()
and closes at
snd_seq_ioctl_create_queue()->queueptr()->snd_use_lock_use(). Between
these two calls, a different thread could delete the queue and possibly
re-create a different queue in the same location in queue_list.

This change prevents this situation by calling snd_use_lock_use() from
snd_seq_queue_alloc() prior to calling queue_list_add(). It is then the
caller's responsibility to call snd_use_lock_free(&q->use_lock).

      ASoC: codecs: make snd_soc_platform_driver const · 0ed6f157
      由 Bhumika Goyal 提交于 
      Make these const as they are either passed as the 2nd argument to the
function devm_snd_soc_register_platform or snd_soc_register_platform,
and the arguments are of type const.
Done using Coccinelle.

      ALSA: seq: Fix CONFIG_SND_SEQ_MIDI dependency · 4d3a8693
      由 Takashi Iwai 提交于 
      The commit 0181307a ("ALSA: seq: Reorganize kconfig and build")
rewrote the dependency of each sequencer module in a standard way, but
there was one change applied mistakenly: CONFIG_SND_SEQ_MIDI isn't
enabled properly by CONFIG_SND_RAWMIDI.  I seem to have changed the
wrong one instead, CONFIG_SND_SEQ_MIDI_EMUL, which is eventually
reverse-selected by CONFIG_SND_SEQ_MIDI itself.  This ended up the
lack of snd-seq-midi module as reported below.

The fix is to put def_tristate properly to CONFIG_SND_SEQ_MIDI instead
of *_MIDI_EMUL entry.
