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: ccree - Correctly handle return of sg_nents_for_len

2025-11-22T02:04:50+00:00

Fix error handling in cc_map_hash_request_update where sg_nents_for_len return value was assigned to u32, converting negative errors to large positive values before passing to sg_copy_to_buffer. Check sg_nents_for_len return value and propagate errors before assigning to areq_ctx->in_nents.

crypto: drivers - Remove redundant pm_runtime_mark_last_busy() calls

2025-07-18T10:51:59+00:00

pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(), pm_runtime_autosuspend() and pm_request_autosuspend() now include a call to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to pm_runtime_mark_last_busy(). Signed-off-by: Sakari Ailus Signed-off-by: Herbert Xu

crypto: ccree - Don't use %pK through printk

2025-06-23T09:00:27+00:00

In the past %pK was preferable to %p as it would not leak raw pointer values into the kernel log. Since commit ad67b74d2469 ("printk: hash addresses printed with %p") the regular %p has been improved to avoid this issue. Furthermore, restricted pointers ("%pK") were never meant to be used through printk(). They can still unintentionally leak raw pointers or acquire sleeping locks in atomic contexts. Switch to the regular pointer formatting which is safer and easier to reason about. Signed-off-by: Thomas Weißschuh Signed-off-by: Herbert Xu

crypto: drivers - Switch back to struct platform_driver::remove()

2024-10-19T00:44:30+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/crypto to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

crypto: ccree - Silence gcc format-truncation false positive warnings

2023-11-17T11:16:28+00:00

The heuristics used by gcc triggers false positive truncation warnings in hifn_alg_alloc. The warning triggered by the strings here are clearly false positives (see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95755). Add checks on snprintf calls to silence these warnings, including the one for cra_driver_name even though it does not currently trigger a gcc warning. Signed-off-by: Herbert Xu
