[IPV6]: Generalise tcp_v6_search_req & tcp_v6_synq_add More work is needed tho to introduce inet6_request_sock from tcp6_request_sock, in the same layout considerations as ipv6_pinfo in inet_sock, next changeset will do that.

inet*.h: Remove extern from function prototypes There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block.

inet: Fix get port to handle zero port number with soreuseport set A user may call listen with binding an explicit port with the intent that the kernel will assign an available port to the socket. In this case inet_csk_get_port does a port scan. For such sockets, the user may also set soreuseport with the intent a creating more sockets for the port that is selected. The problem is that the initial socket being opened could inadvertently choose an existing and unreleated port number that was already created with soreuseport. This patch adds a boolean parameter to inet_bind_conflict that indicates rather soreuseport is allowed for the check (in addition to sk->sk_reuseport). In calls to inet_bind_conflict from inet_csk_get_port the argument is set to true if an explicit port is being looked up (snum argument is nonzero), and is false if port scan is done.

ipv4: add a sock pointer to ip_queue_xmit() ip_queue_xmit() assumes the skb it has to transmit is attached to an inet socket. Commit 31c70d5956fc ("l2tp: keep original skb ownership") changed l2tp to not change skb ownership and thus broke this assumption. One fix is to add a new 'struct sock *sk' parameter to ip_queue_xmit(), so that we do not assume skb->sk points to the socket used by l2tp tunnel.
