      ALSA: hdspm - Fix midi port initialization · 7c7102b7
      Adrian Knoth 提交于
      Depending on the model and the presence of a TCO module, the number of
      midi ports varies. Some have 1 port (MADIface), some have 2 (default),
      with TCO, there are 3.
      
      Don't hardcode the number of midi ports to initialize.
      
      This patch also fixes a boot lockup on MADIface.

      Original patch by Dan Rosenberg <drosenberg@vsecurity.com> under commit
      e68d3b31. I'm copying his text here:
      
      The SNDRV_HDSPM_IOCTL_GET_CONFIG_INFO ioctl in hdspm.c allow unprivileged
      users to read uninitialized kernel stack memory, because several fields
      of the hdspm_config struct declared on the stack are not altered
      or zeroed before being copied back to the user.  This patch takes care
      of it.

      ALSA: usb-audio: fix oops due to cleanup race when disconnecting · 382225e6
      Takashi Iwai 提交于
      When a USB audio device is disconnected, snd_usb_audio_disconnect()
      kills all audio URBs.  At the same time, the application, after being
      notified of the disconnection, might close the device, in which case
      ALSA calls the .hw_free callback, which should free the URBs too.
      
      Commit de1b8b93 "[ALSA] Fix hang-up at disconnection of usb-audio"
      prevented snd_usb_hw_free() from freeing the URBs to avoid a hang that
      resulted from this race, but this introduced another race because the
      URB callbacks could now be executed after snd_usb_hw_free() has
      returned, and try to access already freed data.
      
      Fix the first race by introducing a mutex to serialize the disconnect
      callback and all PCM callbacks that manage URBs (hw_free and hw_params).
