Daniel Borkmann 9013341594 bpf, verifier: detect misconfigured mem, size argument pair ... I've seen two patch proposals now for helper additions that used ARG_PTR_TO_MEM or similar in reg_X but no corresponding ARG_CONST_SIZE in reg_X+1. Verifier won't complain in such case, but it will omit verifying the memory passed to the helper thus ending up badly. Detect such buggy helper function signature and bail out during verification rather than finding them through review.
