[PATCH v2] ALSA: hda/realtek: More robust component matching for CS35L41
by Takashi Iwai 30 Sep '22

30 Sep '22

As the previous commit implies, a system may have a different SPI bus number that is embedded in the device string. And, assuming the fixed bus number is rather fragile; it may be assigned differently depending on the configuration or on the boot environment. Once when a bus number change happens, the binding fails, resulting in the silence. This patch tries to make the matching a bit more relaxed, allowing to bind with a different bus number (or without it). So the previous fix, the introduction of ALC245_FIXUP_CS35L41_SPI1_2 fixup became superfluous, and this is unified to ALC245_FIXUP_CS35L41_SPI_2.

[PATCH -next 0/4] Fix PM disable depth imbalance in probe
by Zhang Qilong 30 Sep '22

30 Sep '22

The pm_runtime_enable will increase power disable depth. Thus a pairing decrement is needed on the error handling path to keep it balanced according to context. We fix it by moving pm_runtime_enable to the endding of probe.

[PATCH] ASoC: core: clarify the driver name initialization
by Jaroslav Kysela 30 Sep '22

30 Sep '22

The driver field in the struct snd_ctl_card_info is a valid user space identifier. Actually, many ASoC drivers do not care and let to initialize this field using a standard wrapping method. Unfortunately, in this way, this field becomes unusable and unreadable for the drivers with longer card names. Also, there is a possibility to have clashes (driver field has only limit of 15 characters). This change will print an error when the wrapping is used. The developers of the affected drivers should fix the problem. Also, it does not make sense to set the driver field to the card name composed from DMI. This card name is longer in most (all?) cases. Use a generic "ASoC-DMI" string here.

[PATCH] ASoC: soc-pcm: fix fe and be race when accessing substream->runtime
by Eugeniu Rosca 29 Sep '22

29 Sep '22

From: xiao jin <jin.xiao(a)intel.com> After start of fe and be, fe might go to close without triggering STOP, and substream->runtime is freed. However, be is still at START state and its substream->runtime still points to the freed runtime. Later on, FE is opened/started again, and triggers STOP. snd_pcm_do_stop => dpcm_fe_dai_trigger => dpcm_fe_dai_do_trigger => dpcm_be_dai_trigger => dpcm_do_trigger => soc_pcm_trigger => skl_platform_pcm_trigger skl_platform_pcm_trigger accesses the freed old runtime data and kernel panic. The patch fixes it by assigning be_substream->runtime in dpcm_be_dai_startup when be's state is START.

A divide error bug in snd_pcm_write
by butt3rflyh4ck 29 Sep '22

29 Sep '22

Hi, there is a divide error bug in snd_pcm_write in sound/core/pcm_native.c in the latest kernel. ##Root Cause When open the device of /dev/snd/pcmC#D#p, there would attach a runtime to pcm->substream via snd_pcm_open_substream. see the code below: ``` int snd_pcm_attach_substream(struct snd_pcm *pcm, int stream, struct file *file, struct snd_pcm_substream **rsubstream) { ...... runtime = kzalloc(sizeof(*runtime), GFP_KERNEL); if (runtime == NULL) return -ENOMEM; size = PAGE_ALIGN(sizeof(struct snd_pcm_mmap_status)); runtime->status = alloc_pages_exact(size, GFP_KERNEL); if (runtime->status == NULL) { kfree(runtime); return -ENOMEM; } memset(runtime->status, 0, size); size = PAGE_ALIGN(sizeof(struct snd_pcm_mmap_control)); runtime->control = alloc_pages_exact(size, GFP_KERNEL); if (runtime->control == NULL) { free_pages_exact(runtime->status, PAGE_ALIGN(sizeof(struct snd_pcm_mmap_status))); kfree(runtime); return -ENOMEM; } memset(runtime->control, 0, size); init_waitqueue_head(&runtime->sleep); init_waitqueue_head(&runtime->tsleep); runtime->status->state = SNDRV_PCM_STATE_OPEN; mutex_init(&runtime->buffer_mutex); atomic_set(&runtime->buffer_accessing, 0); substream->runtime = runtime; substream->private_data = pcm->private_data; substream->ref_count = 1; substream->f_flags = file->f_flags; substream->pid = get_pid(task_pid(current)); pstr->substream_opened++; *rsubstream = substream; return 0; } ``` It would kzmalloc a new runtime. And initialize runtime simply. If we write some data to the device. it would call snd_pcm_write or snd_pcm_writev. and read some date from the device, it would call snd_pcm_read or snd_pcm_readv. Anyway, the four function would use data of runtime, but some data of runtime is NULL not be initialized, see the code below: ``` static ssize_t snd_pcm_write(struct file *file, const char __user *buf, size_t count, loff_t * offset) { struct snd_pcm_file *pcm_file; struct snd_pcm_substream *substream; struct snd_pcm_runtime *runtime; snd_pcm_sframes_t result; pcm_file = file->private_data; substream = pcm_file->substream; if (PCM_RUNTIME_CHECK(substream)) return -ENXIO; runtime = substream->runtime; if (runtime->status->state == SNDRV_PCM_STATE_OPEN || runtime->status->state == SNDRV_PCM_STATE_DISCONNECTED) return -EBADFD; if (!frame_aligned(runtime, count)) /////// [1] return -EINVAL; count = bytes_to_frames(runtime, count); /////// [2] result = snd_pcm_lib_write(substream, buf, count); if (result > 0) result = frames_to_bytes(runtime, result); return result; } ``` [1] call frame_aligned to aligned. ``` static inline int frame_aligned(struct snd_pcm_runtime *runtime, ssize_t bytes) { return bytes % runtime->byte_align == 0; } ``` but runtime->byte_align is NULL. [2] call bytes_to_frames. ``` static inline ssize_t frames_to_bytes(struct snd_pcm_runtime *runtime, snd_pcm_sframes_t size) { return size * runtime->frame_bits / 8; } ``` but runtime->frame_bits is NULL. ##reproduce it [ 1189.305083][ T4656] divide error: 0000 [#1] PREEMPT SMP [ 1189.305600][ T4656] CPU: 1 PID: 4656 Comm: snd_pcm_write Not tainted 6.0.0-rc7 #16 [ 1189.306157][ T4656] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.13.0-1ubuntu1 04/01/2014 [ 1189.306760][ T4656] RIP: 0010:snd_pcm_write+0x33/0xa0 [ 1189.307155][ T4656] Code: 8b 38 48 85 ff 74 72 48 8b 9f c0 00 00 00 48 85 db 74 66 48 8b 83 00 01 00 00 f7 00 f7 ff ff ff 74 6b 48 89 d0 48 89 d1 31 d2 <48> f7 b3 91 [ 1189.308553][ T4656] RSP: 0018:ffffc9000adc7e68 EFLAGS: 00010246 [ 1189.309034][ T4656] RAX: 0000000000000000 RBX: ffff888048ec2000 RCX: 0000000000000000 [ 1189.309583][ T4656] RDX: 0000000000000000 RSI: 0000000000000000 RDI: ffff888046fc9c00 [ 1189.310163][ T4656] RBP: 0000000000000000 R08: 0000000000000000 R09: 0000000000020026 [ 1189.310679][ T4656] R10: 0000000000000001 R11: 0000000000000000 R12: 0000000000000000 [ 1189.311226][ T4656] R13: ffffc9000adc7f08 R14: 0000000000000000 R15: 0000000000000000 [ 1189.311754][ T4656] FS: 00000000012d8880(0000) GS:ffff88807ec00000(0000) knlGS:0000000000000000 [ 1189.312350][ T4656] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 1189.312780][ T4656] CR2: 0000000020000000 CR3: 000000004b496000 CR4: 00000000000006e0 [ 1189.313234][ T4656] Call Trace: [ 1189.313424][ T4656] <TASK> [ 1189.313597][ T4656] vfs_write+0xe6/0x4d0 [ 1189.313836][ T4656] ksys_write+0x60/0xe0 [ 1189.314071][ T4656] do_syscall_64+0x35/0xb0 [ 1189.314324][ T4656] entry_SYSCALL_64_after_hwframe+0x63/0xcd [ 1189.314734][ T4656] RIP: 0033:0x44dc3d [ 1189.315007][ T4656] Code: 28 c3 e8 36 29 00 00 66 0f 1f 44 00 00 f3 0f 1e fa 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f8 [ 1189.316338][ T4656] RSP: 002b:00007ffcbdf5ef38 EFLAGS: 00000246 ORIG_RAX: 0000000000000001 [ 1189.317012][ T4656] RAX: ffffffffffffffda RBX: 0000000000400530 RCX: 000000000044dc3d [ 1189.317693][ T4656] RDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000000000003 [ 1189.318172][ T4656] RBP: 00007ffcbdf5ef50 R08: 0000000082000000 R09: 0000000000000000 [ 1189.318648][ T4656] R10: 000000000000ffff R11: 0000000000000246 R12: 00000000004030a0 [ 1189.319182][ T4656] R13: 0000000000000000 R14: 00000000004c5018 R15: 0000000000000000 Regrads, butt3rflyh4ck. -- Active Defense Lab of Venustech

[PATCH] ASoC: wcd-mbhc-v2: Revert "ASoC: wcd-mbhc-v2: use pm_runtime_resume_and_get()"
by Krzysztof Kozlowski 29 Sep '22

29 Sep '22

This reverts commit ddea4bbf287b6028eaa15a185d0693856956ecf2 ("ASoC: wcd-mbhc-v2: use pm_runtime_resume_and_get()"), because it introduced double runtime PM put if pm_runtime_get_sync() returns -EACCES: wcd934x-codec wcd934x-codec.3.auto: WCD934X Minor:0x1 Version:0x401 wcd934x-codec wcd934x-codec.3.auto: Runtime PM usage count underflow! The commit claimed no changes in functionality except dropping the reference on -EACCESS. This is exactly the change introducing bug because function calls unconditionally pm_runtime_put_autosuspend() at the end.

[PATCH 0/8] ALSA: hda: Add model option to codec drivers, too
by Takashi Iwai 29 Sep '22

29 Sep '22

Hi, this is a trivial patch set to add the "model" option to each HD-audio codec driver that works equivalently with snd-hda-intel or SOF driver's model option. It makes it easer for users to specify the quirk to the right target.
