      ====================
      sctp: add support for sk_reuseport
      
      sctp sk_reuseport allows multiple socks to listen on the same port and
      addresses, as long as these socks have the same uid. This works pretty
      much as TCP/UDP does, the only difference is that sctp is multi-homing
      and all the bind_addrs in these socks will have to completely matched,
      otherwise listen() will return err.
      
      The below is when 5 sockets are listening on 172.16.254.254:6400 on a
      server, 26 sockets on a client connect to 172.16.254.254:6400 and each
      may be processed by a different socket on the server which is selected
      by hash(lport, pport, paddr) in reuseport_select_sock():

      sctp: process sk_reuseport in sctp_get_port_local · 6ba84574
      Xin Long authored
      When socks' sk_reuseport is set, the same port and address are allowed
      to be bound into these socks who have the same uid.
      
      Note that the difference from sk_reuse is that it allows multiple socks
      to listen on the same port and address.

      sctp: add sock_reuseport for the sock in __sctp_hash_endpoint · 76c6d988
      Xin Long authored
      This is a part of sk_reuseport support for sctp. It defines a helper
      sctp_bind_addrs_check() to check if the bind_addrs in two socks are
      matched. It will add sock_reuseport if they are completely matched,
      and return err if they are partly matched, and alloc sock_reuseport
      if all socks are not matched at all.
      
      It will work until sk_reuseport support is added in
      sctp_get_port_local() in the next patch.
      
      v1->v2:
        - use 'laddr->valid && laddr2->valid' check instead as Marcelo
          pointed in sctp_bind_addrs_check().

      sctp: do reuseport_select_sock in __sctp_rcv_lookup_endpoint · 532ae2f1
      Xin Long authored
      This is a part of sk_reuseport support for sctp, and it selects a
      sock by the hashkey of lport, paddr and dport by default. It will
      work until sk_reuseport support is added in sctp_get_port_local()
      in the next patch.
      
      v1->v2:
        - define lport as __be16 instead of __be32 as Marcelo pointed in
          __sctp_rcv_lookup_endpoint().

            same time. From Eric Dumazet.
