ASoC: SOF: Intel: hda: modify period size constraints for ACE4

2026-04-08T12:15:40Z

Intel ACE4 based products set more strict constraints on HDA BDLE start address and length alignment. Add a constraint to align period size to 128 bytes. The commit removes the "minimum as per HDA spec" comment. This comment was misleading as spec actually does allow a 2 byte BDLE length, and more importantly, period size also directly impacts how the BDLE start addresses are aligned, so it is not sufficient just to consider allowed buffer length.

ASoC: SOF: Intel: fix iteration in is_endpoint_present()

2026-04-06T12:23:32Z

is_endpoint_present() iterates over sdca_data.num_functions, but checks the dai_type according to codec info list, which will cause problems if not all endpoints from the codec info list are present. Make sure the type of actually present functions is compared against target dai_type.

ASoC: SOF: Intel: Fix endpoint index if endpoints are missing

2026-04-06T12:23:31Z

In case of missing endpoints, the sequential numbering will cause wrong mapping. Instead, assign the original DAI index from codec_info_list.

ASoC: SOF: ipc4-topology: Allow bytes controls without initial payload

2026-03-26T11:16:03Z

It is unexpected, but allowed to have no initial payload for a bytes control and the code is prepared to handle this case, but the size check missed this corner case. Update the check for minimal size to allow the initial size to be 0.

ASoC: SOF: topology: reject invalid vendor array size in token parser

2026-03-20T12:52:41Z

sof_parse_token_sets() accepts array->size values that can be invalid for a vendor tuple array header. In particular, a zero size does not advance the parser state and can lead to non-progress parsing on malformed topology data. Validate array->size against the minimum header size and reject values smaller than sizeof(*array) before parsing. This preserves behavior for valid topologies and hardens malformed-input handling.

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00Z

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

Convert 'alloc_flex' family to use the new default GFP_KERNEL argument

2026-02-22T01:09:51Z

This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'. Signed-off-by: Linus Torvalds

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

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
