[PATCH 5.0 078/137] netfilter: fix nf_l4proto_log_invalid to log invalid packets




[ Upstream commit d48668052b2603b6262459625c86108c493588dd ]

It doesn't log a packet if sysctl_log_invalid isn't equal to protonum
OR sysctl_log_invalid isn't equal to IPPROTO_RAW. This sentence is
always true. I believe we need to replace OR to AND.
