Martin KaFai Lau e646b657f6 ipv6: udp: Do a route lookup and update during release_cb ... This patch adds a release_cb for UDPv6. It does a route lookup and updates sk->sk_dst_cache if it is needed. It picks up the left-over job from ip6_sk_update_pmtu() if the sk was owned by user during the pmtu update. It takes a rcu_read_lock to protect the __sk_dst_get() operations because another thread may do ip6_dst_store() without taking the sk lock (e.g. sendmsg). Fixes: 45e4fd2668 ("ipv6: Only create RTF_CACHE routes after encountering pmtu exception") Signed-off-by: Martin KaFai Lau <kafai@fb.com> Reported-by: Wei Wang <weiwan@google.com> Cc: Cong Wang <xiyou.wangcong@gmail.com> Cc: Eric Dumazet <edumazet@google.com> Cc: Wei Wang <weiwan@google.com> Signed-off-by: David S.
