      ALSA: usb-audio: Fix use-after-free of usb_device at disconnect · 6ff1a253
      Takashi Iwai 提交于
      The usb-audio driver implements the deferred device disconnection for
      the device in use.  In this mode, the disconnection callback returns
      immediately while the actual ALSA card object removal happens later
      when all files get closed.  As Shuah reported, this code flow,
      however, leads to a use-after-free, detected by KASAN:

      It's the code trying to clear drvdata of the assigned usb_device where
      the usb_device itself was already released in usb_release_dev() after
      the disconnect callback.
      
      This patch fixes it by checking whether the code path is via the
      disconnect callback, i.e. chip->shutdown flag is set.

      ALSA: hda - Fix mic regression by ASRock mobo fixup · 9a254191
      Takashi Iwai 提交于
      The commit [1a3f0991: ALSA: hda - Fix surround output pins for
      ASRock B150M mobo] introduced a fixup of pin configs for ASRock
      mobos to fix the surround outputs.  However, this overrides the pin
      configs of the mic pins as if they are outputs-only, effectively
      disabling the mic inputs.  Of course, it's a regression wrt mic
      functionality.
      
      Actually the pins 0x18 and 0x1a don't need to be changed; we just need
      to disable the bogus pins 0x14 and 0x15.  Then the auto-parser will
      pick up mic pins as switchable and assign the surround outputs there.
      
      This patch removes the incorrect pin overrides of NID 0x18 and 0x1a
      from the ASRock fixup.

      ALSA: info: Return error for invalid read/write · 6809cd68
      Takashi Iwai 提交于
      Currently the ALSA proc handler allows read or write even if the proc
      file were write-only or read-only.  It's mostly harmless, does thing
      but allocating memory and ignores the input/output.  But it doesn't
      tell user about the invalid use, and it's confusing and inconsistent
      in comparison with other proc files.
      
      This patch adds some sanity checks and let the proc handler returning
      an -EIO error when the invalid read/write is performed.

      ALSA: info: Limit the proc text input size · 027a9fe6
      Takashi Iwai 提交于
      The ALSA proc handler allows currently the write in the unlimited size
      until kmalloc() fails.  But basically the write is supposed to be only
      for small inputs, mostly for one line inputs, and we don't have to
      handle too large sizes at all.  Since the kmalloc error results in the
      kernel warning, it's better to limit the size beforehand.
      
      This patch adds the limit of 16kB, which must be large enough for the
      currently existing code.

      ASoC: sun4i-codec: return error code instead of NULL when create_card fails · 85915b63
      Chen-Yu Tsai 提交于
      When sun4i_codec_create_card fails, we do not assign a proper error
      code to the return value. The return value would be 0 from the previous
      function call, or we would have bailed out sooner. This would confuse
      the driver core into thinking the device probe succeeded, when in fact
      it didn't, leaving various devres based resources lingering.
      
      Make the create_card function pass back a meaningful error code, and
      assign it to the return value.

      x86/smpboot: Init apic mapping before usage · 1e90a13d
      Thomas Gleixner 提交于
      The recent changes, which forced the registration of the boot cpu on UP
      systems, which do not have ACPI tables, have been fixed for systems w/o
      local APIC, but left a wreckage for systems which have neither ACPI nor
      mptables, but the CPU has an APIC, e.g. virtualbox.
      
      The boot process crashes in prefill_possible_map() as it wants to register
      the boot cpu, which needs to access the local apic, but the local APIC is
      not yet mapped.
      
      There is no reason why init_apic_mapping() can't be invoked before
      prefill_possible_map(). So instead of playing another silly early mapping
      game, as the ACPI/mptables code does, we just move init_apic_mapping()
      before the call to prefill_possible_map().
      
      In hindsight, I should have noticed that combination earlier.
      
      Sorry for the churn (also in stable)!

      ACPICA: Dispatcher: Fix order issue of method termination · 25ccd242
      Lv Zheng 提交于
      The last step of the method termination should be the end of the method
      serialization. Otherwise, the steps happening after it will face the race
      issues that cannot be protected by the method serialization mechanism.
      
      This patch fixes this issue by moving the per-method-object deletion code
      prior than the end of the method serialization. Otherwise, the possible
      race issues may result in AE_ALREADY_EXISTS error in a parallel
      environment.
