      [DCCP]: Fix skb->cb conflicts with IP · 028b0275
      Patrick McHardy authored
      
      
      dev_queue_xmit() and the other IP output functions expect to get a skb
      with clear or properly initialized skb->cb. Unlike TCP and UDP, the
      dccp_skb_cb doesn't contain a struct inet_skb_parm at the beginning,
      so the DCCP-specific data is interpreted by the IP output functions.
      This can cause false negatives for the conditional POST_ROUTING hook
      invocation, making the packet bypass the hook.
      
      Add a inet_skb_parm/inet6_skb_parm union to the beginning of
      dccp_skb_cb to avoid clashes. Also add a BUILD_BUG_ON to make
      sure it fits in the cb.
      
      [ Combined with patch from Gerrit Renker to remove two now unnecessary
        memsets of IPCB(skb)->opt ]

      [SOCK] proto: Add hashinfo member to struct proto · ab1e0a13
      Arnaldo Carvalho de Melo authored
      
      
      This way we can remove TCP and DCCP specific versions of
      
      sk->sk_prot->get_port: both v4 and v6 use inet_csk_get_port
      sk->sk_prot->hash:     inet_hash is directly used, only v6 need
                             a specific version to deal with mapped sockets
      sk->sk_prot->unhash:   both v4 and v6 use inet_hash directly
      
      struct inet_connection_sock_af_ops also gets a new member, bind_conflict, so
      that inet_csk_get_port can find the per family routine.
      
      Now only the lookup routines receive as a parameter a struct inet_hashtable.
      
      With this we further reuse code, reducing the difference among INET transport
      protocols.
      
      Eventually work has to be done on UDP and SCTP to make them share this
      infrastructure and get as a bonus inet_diag interfaces so that iproute can be
      used with these protocols.
