ASoC: hdmi-codec: Fix OOB memory accesses

2022-02-08T17:34:03Z

commit 06feec6005c9d9500cd286ec440aabf8b2ddd94d upstream. Correct size of iec_status array by changing it to the size of status array of the struct snd_aes_iec958. This fixes out-of-bounds slab read accesses made by memcpy() of the hdmi-codec driver. This problem is reported by KASAN.

ALSA: rawmidi: introduce SNDRV_RAWMIDI_IOCTL_USER_PVERSION

2021-09-23T07:26:40Z

The new framing mode causes the user space regression, because the alsa-lib code does not initialize the reserved space in the params structure when the device is opened. This change adds SNDRV_RAWMIDI_IOCTL_USER_PVERSION like we do for the PCM interface for the protocol acknowledgment.

ASoC: Intel: Skylake: Support multiple format configs

2021-08-23T15:40:02Z

A module can have two kinds of set params, as per topology requirements. For example, one pre-init and one post-init. But currently, there is support for just one type, as the format_config. This patch extends the format_configs to 4, so as to be able to support pre-init, post-init and post-bind type of set params, for the same module, simultaneously.

ALSA: pcm: Add SNDRV_PCM_INFO_EXPLICIT_SYNC flag

2021-08-14T06:38:25Z

ALSA PCM core has an optimized way to communicate with user-space for its control and status data via mmap on the supported architectures like x86. Depending on the situation, however, we'd rather want to enforce user-space notifying the applptr or hwptr change explicitly via ioctl. For example, the upcoming non-contig and non-coherent buffer handling would need an explicit sync, and this needs to catch the applptr and hwptr changes. Also, ASoC SOF driver will have the SPIB support that has the similar requirement for the explicit control of the applptr and hwptr. This patch adds the new PCM hardware info flag, SNDRV_PCM_INFO_EXPLICIT_SYNC. When this flag is set, PCM core disables both the control and the status mmap, which enforces user-space to update via SYNC_PTR ioctl. In that way, drivers can catch the applptr and hwptr update and apply the sync operation if needed.

ALSA: rawmidi: Add framing mode

2021-05-17T14:02:44Z

This commit adds a new framing mode that frames all MIDI data into 32-byte frames with a timestamp. The main benefit is that we can get accurate timestamps even if userspace wakeup and processing is not immediate. Testing on a Celeron N3150 with this mode has a max jitter of 2.8 ms, compared to the in-kernel seq implementation which has a max jitter of 5 ms during idle and much worse when running scheduler stress tests in parallel.

ALSA: fix kernel-doc markups

2020-10-26T14:26:31Z

Kernel-doc markups should use this format: identifier - description There is a common comment marked, instead, with kernel-doc notation. Some identifiers have different names between their prototypes and the kernel-doc markup.
