2026-03-23drm/amd/ras: Add input pointer validation in ras core helpersSrinivasan Shanmugam-0/+9

2026-03-23drm/amd/ras: Remove redundant NULL check in pending bad-bank list iterationSrinivasan Shanmugam-1/+1
ras_umc_log_pending_bad_bank() walks through a list of pending ECC bad-bank entries. These entries are saved when a bad-bank error cannot be processed immediately, for example during a GPU reset. Later, this function iterates over the pending list and retries logging each bad-bank error. If logging succeeds, the entry is removed from the list and the memory for that node is freed. The loop uses list_for_each_entry_safe(), which already guarantees that ecc_node points to a valid list entry while the loop body is executing. Checking "ecc_node &&" inside the loop is therefore unnecessary and redundant. Fixes the below: drivers/gpu/drm/amd/amdgpu/../ras/rascore/ras_umc.c:225 ras_umc_log_pending_bad_bank() warn: variable dereferenced before check 'ecc_node' (see line 223) Fixes: 7a3f9c0992c4 ("drm/amd/ras: Add umc common ras functions") Cc: Dan Carpenter <dan.carpenter@linaro.org> Cc: YiPeng Chai <YiPeng.Chai@amd.com> Cc: Tao Zhou <tao.zhou1@amd.com> Cc: Hawking Zhang <Hawking.Zhang@amd.com> Cc: Christian König <christian.koenig@amd.com> Cc: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Srinivasan Shanmugam <srinivasan.shanmugam@amd.com> Reviewed-by: YiPeng Chai <YiPeng.Chai@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2026-03-17drm/amd/ras: Fix NULL deref in ras_core_get_utc_second_timestamp()Srinivasan Shanmugam-2/+5
ras_core_get_utc_second_timestamp() retrieves the current UTC timestamp (in seconds since the Unix epoch) through a platform-specific RAS system callback and is used for timestamping RAS error events. The function checks ras_core in the conditional statement before calling the sys_fn callback. However, when the condition fails, the function prints an error message using ras_core->dev. If ras_core is NULL, this can lead to a potential NULL pointer dereference when accessing ras_core->dev. Add an early NULL check for ras_core at the beginning of the function and return 0 when the pointer is not valid. This prevents the dereference and makes the control flow clearer.

2026-02-21Convert 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>
2026-02-21Convert '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>
