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 Acked-by: Hannes Frederic Sowa Signed-off-by: David S.
