From e2f387d2df0ece6d4418bb09bef7802cfaf7142d Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Fri, 25 Aug 2017 02:59:41 +0200 Subject: netfilter: conntrack: don't log "invalid" icmpv6 connections When enabling logging for invalid connections we currently also log most icmpv6 types, which we don't track intentionally (e.g. neigh discovery). "invalid" should really mean "invalid", i.e. short header or bad checksum. We don't do any logging for icmp(v4) either, its just useless noise.
