Xin Long d7ab5cdce5 sctp: update dst pmtu with the correct daddr ... When processing pmtu update from an icmp packet, it calls .update_pmtu with sk instead of skb in sctp_transport_update_pmtu. However for sctp, the daddr in the transport might be different from inet_sock->inet_daddr or sk->sk_v6_daddr, which is used to update or create the route cache. The incorrect daddr will cause a different route cache created for the path. So before calling .update_pmtu, inet_sock->inet_daddr/sk->sk_v6_daddr should be updated with the daddr in the transport, and update it back after it's done. The issue has existed since route exceptions introduction. Fixes: 4895c771c7 ("ipv4: Add FIB nexthop exceptions.")
