Florian Westphal ce7de847f1 netfilter: conntrack: set icmpv6 redirects as RELATED ... [ Upstream commit 7d7cfb48d8 ] icmp conntrack will set icmp redirects as RELATED, but icmpv6 will not do this. For icmpv6, only icmp errors (code <= 128) are examined for RELATED state. ICMPV6 Redirects are part of neighbour discovery mechanism, those are handled by marking a selected subset (e.g. neighbour solicitations) as UNTRACKED, but not REDIRECT -- they will thus be flagged as INVALID. Add minimal support for REDIRECTs. No parsing of neighbour options is added for simplicity, so this will only check that we have the embeeded original header (ND_OPT_REDIRECT_HDR), and then attempt to do a flow lookup for this tuple. Also extend the existing test case to cover redirects. Fixes: 9fb9cbb108 ("[NETFILTER]: Add nf_conntrack subsystem.")
