      ALSA: usb-audio: UAC2 jack detection · 5a222e84
      Andrew Chant authored
      This implements UAC2 jack detection support, presenting
      jack status as a boolean read-only mono mixer.
      
      The presence of any channel in the UAC2_TE_CONNECTOR
      control for a terminal will result in the mixer saying
      the jack is connected.
      
      Mixer naming follows the convention in sound/core/ctljack.c,
      terminating the mixer with " Jack".
      For additional clues as to which jack is being presented,
      the name is prefixed with " - Input Jack" or " - Output Jack"
      depending on if it's an input or output terminal.
      
      This is required because terminal names are ambiguous
      between inputs and outputs and often duplicated -
      Bidirectional terminal types (0x400 -> 0x4FF)
      "... may be used separately for input only or output only.
      These types require two Terminal descriptors. Both have the same type."
      (quote from "USB Device Class Definition for Terminal Types")
      
      Since bidirectional terminal types are common for headphone adapters,
      this distinguishes between two otherwise identically-named
      jack controls.
      
      Tested with a UAC2 audio device with connector control capability.

      ALSA: pcm: Return -EBUSY for OSS ioctls changing busy streams · 40cab6e8
      Takashi Iwai authored
      OSS PCM stream management isn't modal but it allows ioctls issued at
      any time for changing the parameters.  In the previous hardening
      patch ("ALSA: pcm: Avoid potential races between OSS ioctls and
      read/write"), we covered these races and prevent the corruption by
      protecting the concurrent accesses via params_lock mutex.  However,
      this means that some ioctls that try to change the stream parameter
      (e.g. channels or format) would be blocked until the read/write
      finishes, and it may take really long.
      
      Basically changing the parameter while reading/writing is an invalid
      operation, hence it's even more user-friendly from the API POV if it
      returns -EBUSY in such a situation.
      
      This patch adds such checks in the relevant ioctls with the addition
      of read/write access refcount.

      ALSA: pcm: Avoid potential races between OSS ioctls and read/write · 02a5d692
      Takashi Iwai authored
      Although we apply the params_lock mutex to the whole read and write
      operations as well as snd_pcm_oss_change_params(), we may still face
      some races.
      
      First off, the params_lock is taken inside the read and write loop.
      This is intentional for avoiding the too long locking, but it allows
      the in-between parameter change, which might lead to invalid
      pointers.  We check the readiness of the stream and set up via
      snd_pcm_oss_make_ready() at the beginning of read and write, but it's
      called only once, by assuming that it remains ready in the rest.
      
      Second, many ioctls that may change the actual parameters
      (i.e. setting runtime->oss.params=1) aren't protected, hence they can
      be processed in a half-baked state.
      
      This patch is an attempt to plug these holes.  The stream readiness
      check is moved inside the read/write inner loop, so that the stream is
      always set up in a proper state before further processing.  Also, each
      ioctl that may change the parameter is wrapped with the params_lock
      for avoiding the races.
      
      The issues were triggered by syzkaller in a few different scenarios,
      particularly the one below appearing as GPF in loopback_pos_update.

      ALSA: usb-audio: Integrate native DSD support for ITF-USB based DACs. · f3b906d7
      Nobutaka Okabe authored
      Integrate the native DSD support quirk codes of "ITF-USB DSD" based DACs.
      
      Now, "is_itf_usb_dsd_2alts_dac()" and "is_itf_usb_dsd_3alts_dac()" is
      integrated into one function "is_itf_usb_dsd_dac()".
      So, remove the logic to distinguish UD-501 and UD-501V2 by the
      "Product Name".
      
      The integration is possible by changing the following two functions.
      
      - snd_usb_select_mode_quirk():
      Change the determination condition of the DSD mode switch command,
      from the altset number being used, to the audio format being played.
      Actually, this operation is same as playback using ASIO driver in
      Windows environment.
      
      - snd_usb_interface_dsd_format_quirk():
      To which altset supports native DSD is determined by the number of altsets.
      Previously, it's a constant "2" or "3".

      ALSA: aloop: Fix access to not-yet-ready substream via cable · 8e6b1a72
      Takashi Iwai authored
      In loopback_open() and loopback_close(), we assign and release the
      substream object to the corresponding cable in a racy way.  It's
      neither locked nor done in the right position.  The open callback
      assigns the substream before its preparation finishes, hence the other
      side of the cable may pick it up, which may lead to the invalid memory
      access.
      
      This patch addresses these: move the assignment to the end of the open
      callback, and wrap with cable->lock for avoiding concurrent accesses.

      ALSA: aloop: Sync stale timer before release · 67a01afa
      Takashi Iwai authored
      The aloop driver tries to stop the pending timer via timer_del() in
      the trigger callback and in the close callback.  The former is
      correct, as it's an atomic operation, while the latter expects that
      the timer gets really removed and proceeds the resource releases after
      that.  But timer_del() doesn't synchronize, hence the running timer
      may still access the released resources.
      
      A similar situation can be also seen in the prepare callback after
      trigger(STOP) where the prepare tries to re-initialize the things
      while a timer is still running.
      
      The problems like the above are seen indirectly in some syzkaller
      reports (although it's not 100% clear whether this is the only cause,
      as the race condition is quite narrow and not always easy to
      trigger).
      
      For addressing these issues, this patch adds the explicit alls of
      timer_del_sync() in some places, so that the pending timer is properly
      killed / synced.

      ALSA: hda - Force polling mode on CFL for fixing codec communication · a8d7bde2
      Takashi Iwai authored
      We've observed too long probe time with Coffee Lake (CFL) machines,
      and the likely cause is some communication problem between the
      HD-audio controller and the codec chips.  While the controller expects
      an IRQ wakeup for each codec response, it seems sometimes missing, and
      it takes one second for the controller driver to time out and read the
      response in the polling mode.
      
      Although we aren't sure about the real culprit yet, in this patch, we
      put a workaround by forcing the polling mode as default for CFL
      machines; the polling mode itself isn't too heavy, and much better
      than other workarounds initially suggested (e.g. disabling
      power-save), at least.

      ALSA: hda/realtek - Always immediately update mute LED with pin VREF · e40bdb03
      Takashi Iwai authored
      Some HP laptops have a mute mute LED controlled by a pin VREF.  The
      Realtek codec driver updates the VREF via vmaster hook by calling
      snd_hda_set_pin_ctl_cache().
      
      This works fine as long as the driver is running in a normal mode.
      However, when the VREF change happens during the codec being in
      runtime PM suspend, the regmap access will skip and postpone the
      actual register change.  This ends up with the unchanged LED status
      until the next runtime PM resume even if you change the Master mute
      switch.  (Interestingly, the machine keeps the LED status even after
      the codec goes into D3 -- but it's another story.)
      
      For improving this usability, let the driver temporarily powering up /
      down only during the pin VREF change.  This can be achieved easily by
      wrapping the call with snd_hda_power_up_pm() / *_down_pm().

      dmaengine: mv_xor_v2: Fix clock resource by adding a register clock · 3cd2c313
      Gregory CLEMENT authored
      On the CP110 components which are present on the Armada 7K/8K SoC we need
      to explicitly enable the clock for the registers. However it is not
      needed for the AP8xx component, that's why this clock is optional.
      
      With this patch both clock have now a name, but in order to be backward
      compatible, the name of the first clock is not used. It allows to still
      use this clock with a device tree using the old binding.

      ALSA: pcm: Fix UAF in snd_pcm_oss_get_formats() · 01c0b426
      Takashi Iwai authored
      snd_pcm_oss_get_formats() has an obvious use-after-free around
      snd_mask_test() calls, as spotted by syzbot.  The passed format_mask
      argument is a pointer to the hw_params object that is freed before the
      loop.  What a surprise that it has been present since the original
      code of decades ago...

      Pull device mapper fixes from Mike Snitzer:
      
       - Fix an uninitialized variable false warning in dm bufio
      
       - Fix DM's passthrough ioctl support to be race free against an
         underlying device being removed.
      
       - Fix corner-case of DM raid resync reporting if/when the raid becomes
         degraded during resync; otherwise automated raid repair will fail.
      
       - A few DM multipath fixes to make non-SCSI optimizations, that were
         introduced during the 4.16 merge, useful for all non-SCSI devices,
         rather than narrowly define this non-SCSI mode in terms of "nvme".
      
         This allows the removal of "queue_mode nvme" that really didn't need
         to be introduced. Instead DM core will internalize whether
         nvme-specific IO submission optimizations are doable and DM multipath
         will only do SCSI-specific device handler operations if SCSI is in
         use.
