[PATCH AUTOSEL 5.18 08/39] ALSA: hda: Fix page fault in snd_hda_codec_shutdown()
by Sasha Levin 14 Aug '22

14 Aug '22

From: Cezary Rojewski <cezary.rojewski(a)intel.com> [ Upstream commit 980b3a8790b402e959a6d773b38b771019682be1 ] If early probe of HDAudio bus driver fails e.g.: due to missing firmware file, snd_hda_codec_shutdown() ends in manipulating uninitialized codec->pcm_list_head causing page fault. Iinitialization of HDAudio codec in ASoC is split in two: - snd_hda_codec_device_init() - snd_hda_codec_device_new() snd_hda_codec_device_init() is called during probe_codecs() by HDAudio bus driver while snd_hda_codec_device_new() is called by codec-component's ->probe(). The second call will not happen until all components required by related sound card are present within the ASoC framework. With firmware failing to load during the PCI's deferred initialization i.e.: probe_work(), no platform components are ever registered. HDAudio codec enumeration is done at that point though, so the codec components became registered to ASoC framework, calling snd_hda_codec_device_init() in the process. Now, during platform reboot snd_hda_codec_shutdown() is called for every codec found on the HDAudio bus causing oops if any of them has not completed both of their initialization steps. Relocating field initialization fixes the issue.

[PATCH AUTOSEL 5.19 39/48] ALSA: control: Use deferred fasync helper

From: Takashi Iwai <tiwai(a)suse.de> [ Upstream commit 4a971e84a7ae10a38d875cd2d4e487c8d1682ca3 ] For avoiding the potential deadlock via kill_fasync() call, use the new fasync helpers to defer the invocation from the control API. Note that it's merely a workaround. Another note: although we haven't received reports about the deadlock with the control API, the deadlock is still potentially possible, and it's better to align the behavior with other core APIs (PCM and timer); so let's move altogether.

[PATCH AUTOSEL 5.19 36/48] ALSA: core: Add async signal helpers
by Sasha Levin 14 Aug '22

14 Aug '22

From: Takashi Iwai <tiwai(a)suse.de> [ Upstream commit ef34a0ae7a2654bc9e58675e36898217fb2799d8 ] Currently the call of kill_fasync() from an interrupt handler might lead to potential spin deadlocks, as spotted by syzkaller. Unfortunately, it's not so trivial to fix this lock chain as it's involved with the tasklist_lock that is touched in allover places. As a temporary workaround, this patch provides the way to defer the async signal notification in a work. The new helper functions, snd_fasync_helper() and snd_kill_faync() are replacements for fasync_helper() and kill_fasync(), respectively. In addition, snd_fasync_free() needs to be called at the destructor of the relevant file object.

[PATCH AUTOSEL 5.19 26/48] ASoC: Intel: sof_es8336: ignore GpioInt when looking for speaker/headset GPIO lines
by Sasha Levin 14 Aug '22

14 Aug '22

From: Andrey Turkin <andrey.turkin(a)gmail.com> [ Upstream commit 751e77011f7a43a204bf2a5d02fbf5f8219bc531 ] This fixes speaker GPIO detection on machines those ACPI tables list their jack detection GpioInt before output GpioIo. GpioInt entry can never be the speaker/headphone amplifier control so it makes sense to only look for GpioIo entries when looking for them.
