      udp: add rehash on connect() · 719f8358
      Eric Dumazet authored
      commit 30fff923
      
       introduced in linux-2.6.33 (udp: bind() optimisation)
      added a secondary hash on UDP, hashed on (local addr, local port).
      
      Problem is that following sequence :
      
      fd = socket(...)
      connect(fd, &remote, ...)
      
      not only selects remote end point (address and port), but also sets
      local address, while UDP stack stored in secondary hash table the socket
      while its local address was INADDR_ANY (or ipv6 equivalent)
      
      Sequence is :
       - autobind() : choose a random local port, insert socket in hash tables
                    [while local address is INADDR_ANY]
       - connect() : set remote address and port, change local address to IP
                    given by a route lookup.
      
      When an incoming UDP frame comes, if more than 10 sockets are found in
      primary hash table, we switch to secondary table, and fail to find
      socket because its local address changed.
      
      One solution to this problem is to rehash datagram socket if needed.
      
      We add a new rehash(struct socket *) method in "struct proto", and
      implement this method for UDP v4 & v6, using a common helper.
      
      This rehashing only takes care of secondary hash table, since primary
      hash (based on local port only) is not changed.

      inet: rename some inet_sock fields · c720c7e8
      Eric Dumazet authored
      
      
      In order to have better cache layouts of struct sock (separate zones
      for rx/tx paths), we need this preliminary patch.
      
      Goal is to transfert fields used at lookup time in the first
      read-mostly cache line (inside struct sock_common) and move sk_refcnt
      to a separate cache line (only written by rx path)
      
      This patch adds inet_ prefix to daddr, rcv_saddr, dport, num, saddr,
      sport and id fields. This allows a future patch to define these
      fields as macros, like sk_refcnt, without name clashes.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
