Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

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

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

Replace sprintf() with sysfs_emit() in verify_compress_show() and sync_mode_show(). sysfs_emit() is preferred to format sysfs output as it provides better bounds checking. No functional changes. Signed-off-by: Thorsten Blum Acked-by: Kanchana P Sridhar Signed-off-by: Herbert Xu

crypto: qat - fix duplicate restarting msg during AER error

2025-12-29T00:44:14+00:00

The restarting message from PF to VF is sent twice during AER error handling: once from adf_error_detected() and again from adf_disable_sriov(). This causes userspace subservices to shutdown unexpectedly when they receive a duplicate restarting message after already being restarted. Avoid calling adf_pf2vf_notify_restarting() and adf_pf2vf_wait_for_restarting_complete() from adf_error_detected() so that the restarting msg is sent only once from PF to VF.

crypto: iaa - Fix out-of-bounds index in find_empty_iaa_compression_mode

2025-12-19T06:47:47+00:00

The local variable 'i' is initialized with -EINVAL, but the for loop immediately overwrites it and -EINVAL is never returned. If no empty compression mode can be found, the function would return the out-of-bounds index IAA_COMP_MODES_MAX, which would cause an invalid array access in add_iaa_compression_mode(). Fix both issues by returning either a valid index or -EINVAL.
