Daniel Borkmann 3f96a53211 net: sctp: rfc4443: do not report ICMP redirects to user space ... Adapt the same behaviour for SCTP as present in TCP for ICMP redirect messages. For IPv6, RFC4443, section 2.4. says: ... (e) An ICMPv6 error message MUST NOT be originated as a result of receiving the following: ... (e.2) An ICMPv6 redirect message [IPv6-DISC]. ... Therefore, do not report an error to user space, just invoke dst's redirect callback and leave, same for IPv4 as done in TCP as well. The implication w/o having this patch could be that the reception of such packets would generate a poll notification and in worst case it could even tear down the whole connection. Therefore, stop updating sk_err on redirects.
