      ALSA: firewire: fix NULL pointer dereference when releasing uninitialized data of iso-resource · 0c264af7
      Takashi Sakamoto authored
      When calling 'iso_resource_free()' for uninitialized data, this function
      causes NULL pointer dereference due to its 'unit' member. This occurs when
      unplugging audio and music units on IEEE 1394 bus at failure of card
      This commit fixes the bug. The bug exists since kernel v4.5.

      A Senheisser headset requires the typical sample-rate quirk for

      ALSA: seq: 2nd attempt at fixing race creating a queue · 7e1d90f6
      Daniel Mentz authored
      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
      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).

      ALSA: seq: Fix CONFIG_SND_SEQ_MIDI dependency · 4d3a8693
      Takashi Iwai authored
      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.

      NFSv4.1: Fix a race where CB_NOTIFY_LOCK fails to wake a waiter · b7dbcc0e
      Benjamin Coddington authored
      nfs4_retry_setlk() sets the task's state to TASK_INTERRUPTIBLE within the
      same region protected by the wait_queue's lock after checking for a
      notification from CB_NOTIFY_LOCK callback.  However, after releasing that
      lock, a wakeup for that task may race in before the call to
      freezable_schedule_timeout_interruptible() and set TASK_WAKING, then
      freezable_schedule_timeout_interruptible() will set the state back to
      TASK_INTERRUPTIBLE before the task will sleep.  The result is that the task
      will sleep for the entire duration of the timeout.
      Since we've already set TASK_INTERRUPTIBLE in the locked section, just use
      freezable_schedule_timout() instead.

        I have also included a couple of cleanup patches in this pull request
        for OMAP2+, related to the omap_hsmmc driver. The reason is because of
        the changes are also depending on OMAP SoC specific code, so this

      lightnvm: pblk: advance bio according to lba index · 75cb8e93
      Javier González authored
      When a lba either hits the cache or corresponds to an empty entry in the
      L2P table, we need to advance the bio according to the position in which
      the lba is located. Otherwise, we will copy data in the wrong page, thus
      causing data corruption for the application.
      In case of a cache hit, we assumed that bio->bi_iter.bi_idx would
      contain the correct index, but this is no necessarily true. Instead, use
      the local bio advance counter and iterator. This guarantees that lbas
      hitting the cache are copied into the right bv_page.
      In case of an empty L2P entry, we omitted to advance the bio. In the
      cases when the same I/O also contains a cache hit, data corresponding
      to this lba will be copied to the wrong bv_page. Fix this by advancing
      the bio as we do in the case of a cache hit.

      Harsha Priya N authored
      This patch fixes the pop noise in dmic recording using rt5514 on kabylake platform.
      This patch enables the rt5514 to use MCLK instead of BLCK as the sysclock which fixes
      the pop noise.

      ASoC: Intel: Enabling ASRC for RT5663 codec on kabylake platform · 349d63c3
      Harsha Priya N authored
      This patch fixes the cracking noise in rt5663 headphones for kabylake platform
      by calling rt5663_sel_asrc_clk_src() for RT5663_AD_STEREO_FILTER to set ASRC.
      The ASRC function is for asynchronous MCLK and LRCK. For RT5663 ASRC should be
      enabled to  support special i2s clock format like Intel's 100fs.
      ASRC function will track i2s clock and generate a corresponding
      system clock for codec. Calling this function helps select the clock source
      for both RT5663_AD_STEREO_FILTER and RT5663_DA_STEREO_FILTER filters
      which fixes the crackling sound.

      arm64: mmu: Place guard page after mapping of kernel image · 92bbd16e
      Will Deacon authored
      The vast majority of virtual allocations in the vmalloc region are followed
      by a guard page, which can help to avoid overruning on vma into another,
      which may map a read-sensitive device.
      This patch adds a guard page to the end of the kernel image mapping (i.e.
      following the data/bss segments).
