2026-02-21Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds
This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21treewide: Replace kmalloc with kmalloc_obj for non-scalar typesKees Cook
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org>
2025-02-05ASoC: SOF: stream-ipc: Check for cstream nullity in sof_ipc_msg_data()Peter Ujfalusi
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.

2023-01-17ASoC: SOF: Add support for compress API for stream data/offsetDaniel Baluta
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.

2021-10-07ASoC: SOF: Make Intel IPC stream ops genericBud Liviu-Alexandru
This operations should be generic as there is nothing Intel specific. This works well for NXP i.MX8 stream IPC ops. We start by moving sof/intel/intel-ipc.c into sof/stream-ipc.c and rename the functions to be generic. Notice that we use newly introduced snd_sof_dsp_mailbox_read instead of sof_mailbox_read, to make sure that we are not bound to existing MMIO memory access, and we allow platform to implement their own memory access routines.
