ICMPv6: treat dest unreachable codes 5 and 6 as EACCES, not EPROTO
[ Upstream commit 61e76b178dbe7145e8d6afa84bb4ccea71918994 ] RFC 4443 has defined two additional codes for ICMPv6 type 1 (destination unreachable) messages: 5 - Source address failed ingress/egress policy 6 - Reject route to destination Now they are treated as protocol error and icmpv6_err_convert() converts them to EPROTO. RFC 4443 says: "Codes 5 and 6 are more informative subsets of code 1." Treat codes 5 and 6 as code 1 (EACCES) Btw, connect() returning -EPROTO confuses firefox, so that fallback to other/IPv4 addresses does not work: https://bugzilla.mozilla.org/show_bug.cgi?id=910773 Signed-off-by: Jiri Bohac <jbohac@suse.cz> Acked-by: Hannes Frederic Sowa <hannes@stressinduktion.org> Signed-off-by: David S.
