sctp: Make the endpoint hashtable handle multiple network namespaces
- Use struct net in the hash calculation - Use sock_net(endpoint.base.sk) in the endpoint lookups. - On receive calculate the network namespace from skb->dev. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com> Acked-by: Vlad Yasevich <vyasevich@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
