      [NET]: Added GSO header verification · 576a30eb
      Herbert Xu 提交于
      When GSO packets come from an untrusted source (e.g., a Xen guest domain),
      we need to verify the header integrity before passing it to the hardware.
      
      Since the first step in GSO is to verify the header, we can reuse that
      code by adding a new bit to gso_type: SKB_GSO_DODGY.  Packets with this
      bit set can only be fed directly to devices with the corresponding bit
      NETIF_F_GSO_ROBUST.  If the device doesn't have that bit, then the skb
      is fed to the GSO engine which will allow the packet to be sent to the
      hardware if it passes the header check.
      
      This patch changes the sg flag to a full features flag.  The same method
      can be used to implement TSO ECN support.  We simply have to mark packets
      with CWR set with SKB_GSO_ECN so that only hardware with a corresponding
      NETIF_F_TSO_ECN can accept them.  The GSO engine can either fully segment
      the packet, or segment the first MTU and pass the rest to the hardware for
      further segmentation.

      [NET]: move struct proto_ops to const · 90ddc4f0
      Eric Dumazet 提交于
      I noticed that some of 'struct proto_ops' used in the kernel may share
      a cache line used by locks or other heavily modified data. (default
      linker alignement is 32 bytes, and L1_CACHE_LINE is 64 or 128 at
      least)
      
      This patch makes sure a 'struct proto_ops' can be declared as const,
      so that all cpus can share all parts of it without false sharing.
      
      This is not mandatory : a driver can still use a read/write structure
      if it needs to (and eventually a __read_mostly)
      
      I made a global stubstitute to change all existing occurences to make
      them const.
      
      This should reduce the possibility of false sharing on SMP, and
      speedup some socket system calls.

      [IP_SOCKGLUE]: Remove most of the tcp specific calls · d83d8461
      Arnaldo Carvalho de Melo 提交于
      As DCCP needs to be called in the same spots.
      
      Now we have a member in inet_sock (is_icsk), set at sock creation time from
      struct inet_protosw->flags (if INET_PROTOSW_ICSK is set, like for TCP and
      DCCP) to see if a struct sock instance is a inet_connection_sock for places
      like the ones in ip_sockglue.c (v4 and v6) where we previously were looking if
      sk_type was SOCK_STREAM, that is insufficient because we now use the same code
      for DCCP, that has sk_type SOCK_DCCP.

      Linux-2.6.12-rc2 · 1da177e4
      Linus Torvalds 提交于
      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!
