ASoC: SOF: stream-ipc: Check for cstream nullity in sof_ipc_msg_data()

2026-06-01T15:39:31+00:00

[ Upstream commit d8d99c3b5c485f339864aeaa29f76269cc0ea975 ] The nullity of sps->cstream should be checked similarly as it is done in sof_set_stream_data_offset() function. Assuming that it is not NULL if sps->stream is NULL is incorrect and can lead to NULL pointer dereference.

ASoC: SOF: pcm: Clear the susbstream pointer to NULL on close

2026-06-01T15:39:31+00:00

[ Upstream commit 46c7b901e2a03536df5a3cb40b3b26e2be505df6 ] The spcm->stream[substream->stream].substream is set during open and was left untouched. After the first PCM stream it will never be NULL and we have code which checks for substream NULLity as indication if the stream is active or not. For the compressed cstream pointer the same has been done, this change will correct the handling of PCM streams.

ASoC: SOF: compress: return the configured codec from get_params

2026-06-01T15:39:13+00:00

[ Upstream commit 2c4fdd055f92a2fc8602dcd88bcea08c374b7e8b ] The SOF compressed offload path accepts codec parameters in sof_compr_set_params() and forwards them to firmware as extended data in the SOF IPC stream params message. However, sof_compr_get_params() still returns success without filling the snd_codec structure. Since the compress core allocates that structure zeroed and copies it back to userspace on success, SNDRV_COMPRESS_GET_PARAMS returns an all-zero codec description even after the stream has been configured successfully. The stale TODO in this callback conflates get_params() with capability discovery. Supported codec enumeration belongs in get_caps() and get_codec_caps(). get_params() should report the current codec settings. Cache the codec accepted by sof_compr_set_params() in the per-stream SOF compress state and return it from sof_compr_get_params().

ASoC: SOF: Add support for compress API for stream data/offset

[ Upstream commit 090349a9feba3ceee3997d31d68ffe54e5b57acb ] snd_sof_pcm_stream keeps information about both PCM (snd_pcm_substream) and Compress (snd_compr_stream) streams. When PCM substream pointer is NULL this means we are dealing with a compress stream.

ASoC: SOF: Don't allow pointer operations on unconfigured streams

2026-06-01T15:38:53+00:00

commit c5b6285aae050ff1c3ea824ca3d88ac4be1e69c8 upstream. When reporting the pointer for a compressed stream we report the current I/O frame position by dividing the position by the number of channels multiplied by the number of container bytes. These values default to 0 and are only configured as part of setting the stream parameters so this allows a divide by zero to be configured. Validate that they are non zero, returning an error if not Fixes: c1a731c71359 ("ASoC: SOF: compress: Add support for computing timestamps") Cc: stable@vger.kernel.org Link: https://patch.msgid.link/20260326-asoc-compress-tstamp-params-v1-1-3dc735b3d599@kernel.org Signed-off-by: Mark Brown Signed-off-by: Greg Kroah-Hartman
