[PATCH] sound/isa/sb/emu8000: Fix a use after free in snd_emu8000_create_mixer
by Lv Yunlong 26 Apr '21

26 Apr '21

Our code analyzer reported a uaf. In snd_emu8000_create_mixer, the callee snd_ctl_add(..,emu->controls[i]) calls snd_ctl_add_replace(.., kcontrol,..). Inside snd_ctl_add_replace(), if error happens, kcontrol will be freed by snd_ctl_free_one(kcontrol). Then emu->controls[i] points to a freed memory, and the execution comes to __error branch of snd_emu8000_create_mixer. The freed emu->controls[i] is used in snd_ctl_remove(card, emu->controls[i]). My patch set emu->controls[i] to NULL if snd_ctl_add() failed to avoid the uaf.

[PATCH] ALSA: hda/realtek: fix static noise on ALC285 Lenovo laptops
by Sami Loone 26 Apr '21

26 Apr '21

Remove a duplicate vendor+subvendor pin fixup entry as one is masking the other and making it unreachable. Consider the more specific newcomer as a second chance instead. The generic entry is made less strict to also match for laptops with slightly different 0x12 pin configuration. Tested on Lenovo Yoga 6 (AMD) where 0x12 is 0x40000000.

[PATCH] firmware: replace HOTPLUG with UEVENT in FW_ACTION defines

26 Apr '21

With commit 312c004d36ce ("[PATCH] driver core: replace "hotplug" by "uevent"") already in the tree over a decade, update the name of FW_ACTION defines to follow semantics, and reflect what the defines are really meant for, i.e. whether or not generate user space event.

[PATCH] ALSA: usb-audio: Fix implicit sync clearance at stopping stream
by Takashi Iwai 26 Apr '21

26 Apr '21

The recent endpoint management change for implicit feedback mode added a clearance of ep->sync_sink (formerly ep->sync_slave) pointer at snd_usb_endpoint_stop() to assure no leftover for the feedback from the already stopped capture stream. This turned out to cause a regression, however, when full-duplex streams were running and only a capture was stopped. Because of the above clearance of ep->sync_sink pointer, no more feedback is done, hence the playback will stall. This patch fixes the ep->sync_sink clearance to be done only after all endpoints are released, for addressing the regression.

ASoc / PCM recording-related regression between v5.4 and v5.5
by Hin-Tak Leung 24 Apr '21

24 Apr '21

Hi, I am trying to find the cause of a rather unusual regression between kernel v5.4 and v5.5, for an out-of-tree driver on the raspberrypi. Everything looks identical between v5.4 and 5.5, within accountable differences, even when I enable dynamic debugging and echo "file sound/* +p" > /sys/kernel/debug/dynamic_debug/control for the whole of sound sub-system. It records fines against v5.4, but blocks on v5.5, and on ctrl-c, does ^CAborted by signal Interrupt... arecord: pcm_read:2145: read error: Interrupted system call I have gradually replaced the include/sound and sound/ directories between the two (the pi v5.4 and v5.5 kernels are separate branches off linux-stable, so one cannot do ordinary bisects), and narrowed it down to the following 13 commits from 5 people: 4104faaeeda0e23a169c50e43f309ff7435087b1 ASoC: soc-core: disable route checks for legacy devices 4bf2e385aa59c2fae5f880aa25cfd2b470109093 ASoC: core: Init pcm runtime work early to avoid warnings fb5126778333d289b2623a7e6260beeb1ac1b819 ASoC: core: add SND_SOC_BYTES_E dc73d73aa7145f55412611f3eead1e85ae026785 ASoC: add control components management 509ba54fcfd1e45bceebe8ccea59dc496312f1a0 ASoC: soc.h: dobj is used only when SND_SOC_TOPOLOGY e443c20593de9f8efd9b2935ed40eb0bbacce30b ASoC: soc-core: don't call snd_soc_dapm_new_dai_widgets() at snd_soc_register_dai() 5d07519703bc2f0bf19d33652401552a480d68b8 ASoC: soc-core: have legacy_dai_naming at snd_soc_register_dai() e11381f38f34789b374880c4a149e25e8d7f0cfd ASoC: soc-core: add snd_soc_unregister_dai() 4baabbf932ed4f97df8e18cf546d39b7c2138020 ASoC: soc-dpcm: tidyup for_each_dpcm_xx() macro 2b544dd7b43b19fb55ea4fbb3e30b60eb20b7828 ASoC: soc-core: add for_each_rtd_components() and replace 33536a14879515949b065721cdb7fedb276d8e8a ASoC: soc-core: remove for_each_rtdcom_safe() 8ec241c495dde3d19a0459304298c2468c60182b ASoC: soc-core: add snd_soc_pcm_lib_ioctl() b7c5bc45ee94a03a0dc45a862180e17db8ea8e9d ASoC: soc-core: merge soc_free_pcm_runtime() and soc_rtd_free() I think it is overlay / devicetree related, since another audio device of the same family and similar hardware but different overlay works fine. As I already did 'echo "file sound/* +p" > /sys/kernel/debug/dynamic_debug/control' , I likely need some additional debug statement or enable debugging at another part to go further, despite it being a regression in 'include/sound/soc*.h' and 'sound/soc/soc-*'. Building the pi kernel cleanly - from 'make mrproper', copy .config then 'make oldconnfig' - takes about an hour, so switching between the two and compare takes about 3 hours, and quite slow. I can possibly narrow the changes further from the 13 commits (9 of them from Kuninori Morimoto), but I think some more dev_dbg() is needed as the current ones in "sound/*" don't help; and it is worth bring it to alsa-devel since it is so unusual - all the dev_dbg() in kernel/sound/ and the driver side emits to the same messages, v5.4 can records while v5.5 blocks on stuck system call. More details at https://github.com/raspberrypi/linux/issues/4279 and it was initially at https://github.com/respeaker/seeed-voicecard/issues/290 . The "seeed-8mic-voicecard-overlay.dts" is the dts corresponds to the problematic device ; The one with similar hardware but okay is "seeed-4mic-voicecard-overlay.dts" . I am subscribed to alsa-devel actually, but receive it in digest form, and haven't opened the digests for a while... Thanks a lot. Hin-Tak

Warnings on startup

23 Apr '21

alsa-project/alsa-plugins issue #20 was opened from bramtayl: I've been trying to get Julia's PortAudio to load alsa-plugins (it's been a process). I thought I might as well see if I can cut down on the warnings on start up (`using PortAudio` from Julia) and some of them I've been able to knock out but some of them not so much: These ones ``` ALSA lib pcm.c:2660:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear ALSA lib pcm.c:2660:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe ALSA lib pcm.c:2660:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side ``` I got rid of by commenting out lines in my alsa.conf file: ``` # pcm.rear cards.pcm.rear # pcm.center_lfe cards.pcm.center_lfe # pcm.side cards.pcm.side ``` This one ``` ALSA lib pcm_route.c:877:(find_matching_chmap) Found no matching channel map ``` I got rid of by commening out: ``` # pcm.surround21 cards.pcm.surround21 # pcm.surround40 cards.pcm.surround40 # pcm.surround41 cards.pcm.surround41 # pcm.surround50 cards.pcm.surround50 # pcm.surround51 cards.pcm.surround51 # pcm.surround71 cards.pcm.surround71 ``` I'm not sure if these work arounds are the best solutions...shouldn't alsa be able to tell that my laptop doesn't have surround sound? This one is expected, I haven't yet figured out how to build jack on Julia's BinaryBuilder: ``` ALSA lib dlmisc.c:339:(snd_dlobj_cache_get0) Cannot open shared library libasound_module_pcm_jack.so (/home/brandon/.julia/artifacts/d587f48a6815c72dec4b083bf297caec7a8e3f4b/lib/alsa-lib/libasound_module_pcm_jack.so: cannot open shared object file: No such file or directory) ``` These ones are a bit confusing; ``` ALSA lib pcm_oss.c:377:(_snd_pcm_oss_open) Unknown field port ALSA lib pcm_usb_stream.c:486:(_snd_pcm_usb_stream_open) Invalid type for card ``` Is it possible that `oss/50-oss.conf` and `usb_stream/98-usb-stream.conf` need to get updated?

[PATCH v4] ASoC: rt711-sdca: change capture switch controls
by shumingf＠realtek.com 23 Apr '21

23 Apr '21

From: Shuming Fan <shumingf(a)realtek.com> The DAPM event and mixer control could mute/unmute the capture directly. That will be confused that capture still works if the user settings is unmute before the capture. Therefore, this patch uses the variables to record the capture switch status of DAPM and mixer.

[PATCH] ASoC: simple-card: Fix breakage on kontron-sl28-var3-ads2
by Mark Brown 23 Apr '21

23 Apr '21

A KernelCI bisection identified 59c35c44a9cf89 "ASoC: simple-card: add simple_parse_node()" as causing simple-card to fail to instantiate on kontron-sl28-var3-ads2 systems. Since the merge window is expected to open over the weekend drop that commit and subsequent ones which depend on it for now in case other systems are affected too. The boot log showed the error as: <4>[ 9.948821] sysfs: cannot create duplicate filename '/devices/platform/sound/(null)-wm8904-hifi' (backtrace) <3>[ 10.191982] kobject_add_internal failed for (null)-wm8904-hifi with -EEXIST, don't try to register things with the same name in the same directory.
