Analyze and fix the following issue in the Linux kernel code: xfrm: Sanitize marks before insert
Problem Details: Prior to this patch, the mark is sanitized (applying the state's mask to the state's value) only on inserts when checking if a conflicting XFRM state or policy exists. We discovered in Cilium that this same sanitization does not occur in the hot-path __xfrm_state_lookup. In the hot-path, the sk_buff's...
