11 daysConvert more 'alloc_obj' cases to default GFP_KERNEL argumentsLinus Torvalds-2/+1
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 <torvalds@linux-foundation.org>
12 daysConvert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds-9/+9
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>
12 daystreewide: Replace kmalloc with kmalloc_obj for non-scalar typesKees Cook-11/+11
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>

2025-12-10drm/amd/ras: Reduce stack usage in amdgpu_virt_ras_get_cper_records()Srinivasan Shanmugam-4/+13
amdgpu_virt_ras_get_cper_records() was using a large stack array of ras_log_info pointers. This contributed to the frame size warning on this function. Replace the fixed-size stack array: struct ras_log_info *trace[MAX_RECORD_PER_BATCH]; with a heap-allocated array using kcalloc(). We free the trace buffer together with out_buf on all exit paths. If allocation of trace or out_buf fails, we return a generic RAS error code. This reduces stack usage and keeps the runtime behaviour unchanged.

2025-12-08drm/amd/ras: Reduce stack usage in ras_umc_handle_bad_pages()Srinivasan Shanmugam-8/+21
ras_umc_handle_bad_pages() function used a large local array: struct eeprom_umc_record records[MAX_ECC_NUM_PER_RETIREMENT]; Move this array off the stack by allocating it with kcalloc() and freeing it before return. This reduces the stack frame size of ras_umc_handle_bad_pages() and avoids the frame size warning. Fixes the below: drivers/gpu/drm/amd/amdgpu/../ras/rascore/ras_umc.c:498:5: warning: stack frame size (1208) exceeds limit (1024) in 'ras_umc_handle_bad_pages' [-Wframe-larger-than] v2: Removed the duplicate ras_umc_get_new_records() invocation.
