treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

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

crypto: qce - fix priority to be less than ARMv8 CE

2024-12-14T09:21:43+00:00

As QCE is an order of magnitude slower than the ARMv8 Crypto Extensions on the CPU, and is also less well tested, give it a lower priority. Previously the QCE SHA algorithms had higher priority than the ARMv8 CE equivalents, and the ciphers such as AES-XTS had the same priority which meant the QCE versions were chosen if they happened to be loaded later.

crypto: qce - Set DMA alignment explicitly

2022-12-09T10:45:00+00:00

This driver has been implicitly relying on kmalloc alignment to be sufficient for DMA. This may no longer be the case with upcoming arm64 changes. This patch changes it to explicitly request DMA alignment from the Crypto API. Signed-off-by: Herbert Xu
