Eric Dumazet ca10b9e9a8 selinux: add a skb_owned_by() hook ... Commit 90ba9b1986 (tcp: tcp_make_synack() can use alloc_skb()) broke certain SELinux/NetLabel configurations by no longer correctly assigning the sock to the outgoing SYNACK packet. Cost of atomic operations on the LISTEN socket is quite big, and we would like it to happen only if really needed. This patch introduces a new security_ops->skb_owned_by() method, that is a void operation unless selinux is active.
