tcp: make sure skb is not shared before using skb_get()
IPv6 can keep a copy of SYN message using skb_get() in tcp_v6_conn_request() so that caller wont free the skb when calling kfree_skb() later. Therefore TCP fast open has to clone the skb it is queuing in child->sk_receive_queue, as all skbs consumed from receive_queue are freed using __kfree_skb() (ie assuming skb->users == 1) Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: Yuchung Cheng <ycheng@google.com> Fixes: 5b7ed0892f2af ("tcp: move fastopen functions to tcp_fastopen.c") Signed-off-by: David S. Miller <davem@davemloft.net>
