2024-08-16idpf: remove redundant 'req_vec_chunks' NULL checkPavan Kumar Linga1-18/+5
'req_vec_chunks' is used to store the vector info received from the device control plane. The memory for it is allocated in idpf_send_alloc_vectors_msg and returns an error if the memory allocation fails. 'req_vec_chunks' cannot be NULL in the later code flow. So remove the conditional check to extract the vector ids received from the device control plane. Smatch static checker warning: drivers/net/ethernet/intel/idpf/idpf_lib.c:417 idpf_intr_req() error: we previously assumed 'adapter->req_vec_chunks' could be null (see line 360) Reported-by: Dan Carpenter <[email protected]> Closes: https://lore.kernel.org/intel-wired-lan/[email protected]/ Reviewed-by: Dan Carpenter <[email protected]> Signed-off-by: Pavan Kumar Linga <[email protected]> Tested-by: Krishneil Singh <[email protected]> Signed-off-by: Tony Nguyen <[email protected]> Link: https://patch.msgid.link/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>

2024-08-16drm/radeon/evergreen_cs: fix int overflow errors in cs track offsetsNikita Zhandarovich1-31/+31
Several cs track offsets (such as 'track->db_s_read_offset') either are initialized with or plainly take big enough values that, once shifted 8 bits left, may be hit with integer overflow if the resulting values end up going over u32 limit. Same goes for a few instances of 'surf.layer_size * mslice' multiplications that are added to 'offset' variable - they may potentially overflow as well and need to be validated properly. While some debug prints in this code section take possible overflow issues into account, simply casting to (unsigned long) may be erroneous in its own way, as depending on CPU architecture one is liable to get different results. Fix said problems by: - casting 'offset' to fixed u64 data type instead of ambiguous unsigned long. - casting one of the operands in vulnerable to integer overflow cases to u64. - adjust format specifiers in debug prints to properly represent 'offset' values. Found by Linux Verification Center (linuxtesting.org) with static analysis tool SVACE.
