      gianfar: fix compile fail for NET_POLL=y due to struct packing · 62ed839d
      Paul Gortmaker authored
      Commit ee873fda ("gianfar: Pack struct
      gfar_priv_grp into three cachelines") moved the irq number and names
      off into a separate struct and created accessors for them.  However
      it was never tested with NET_POLL enabled, and so some conversions
      that were simply overlooked went undetected until now.
      
      Make the netpoll ones also use the gfar_irq() accessors.

      vlan: adjust vlan_set_encap_proto() for its callers · da8c8724
      Cong Wang authored
      There are two places to call vlan_set_encap_proto():
      vlan_untag() and __pop_vlan_tci().
      
      vlan_untag() assumes skb->data points after mac addr, otherwise
      the following code
      
              vhdr = (struct vlan_hdr *) skb->data;
              vlan_tci = ntohs(vhdr->h_vlan_TCI);
              __vlan_hwaccel_put_tag(skb, vlan_tci);
      
              skb_pull_rcsum(skb, VLAN_HLEN);
      
      won't be correct. But __pop_vlan_tci() assumes points _before_
      mac addr.
      
      In vlan_set_encap_proto(), it looks for some magic L2 value
      after mac addr:
      
              rawp = skb->data;
              if (*(unsigned short *) rawp == 0xFFFF)
      	...
      
      Therefore __pop_vlan_tci() is obviously wrong.
      
      A quick fix is avoiding using skb->data in vlan_set_encap_proto(),
      use 'vhdr+1' is always correct in both cases.

      ipv6: use a stronger hash for tcp · 08dcdbf6
      Eric Dumazet authored
      It looks like its possible to open thousands of TCP IPv6
      sessions on a server, all landing in a single slot of TCP hash
      table. Incoming packets have to lookup sockets in a very
      long list.
      
      We should hash all bits from foreign IPv6 addresses, using
      a salt and hash mix, not a simple XOR.
      
      inet6_ehashfn() can also separately use the ports, instead
      of xoring them.

      net: fec: Ensure that initialization is done prior to request_irq() · 7f7d6c28
      Fabio Estevam authored
      Currently request_irq() is called prior to fec_enet_init() and fec_ptp_init(),
      which causes the following crash on a mx53qsb:

      Pull networking update from David Miller:
      
       1) Checkpoint/restarted TCP sockets now can properly propagate the TCP
          timestamp offset.  From Andrey Vagin.
      
       2) VMWARE VM VSOCK layer, from Andy King.
      
       3) Much improved support for virtual functions and SR-IOV in bnx2x,
          from Ariel ELior.
      
       4) All protocols on ipv4 and ipv6 are now network namespace aware, and
          all the compatability checks for initial-namespace-only protocols is
          removed.  Thanks to Tom Parkin for helping deal with the last major
          holdout, L2TP.
      
       5) IPV6 support in netpoll and network namespace support in pktgen,
          from Cong Wang.
      
       6) Multiple Registration Protocol (MRP) and Multiple VLAN Registration
          Protocol (MVRP) support, from David Ward.
      
       7) Compute packet lengths more accurately in the packet scheduler, from
          Eric Dumazet.
      
       8) Use per-task page fragment allocator in skb_append_datato_frags(),
          also from Eric Dumazet.
      
       9) Add support for connection tracking labels in netfilter, from
          Florian Westphal.
      
      10) Fix default multicast group joining on ipv6, and add anti-spoofing
          checks to 6to4 and 6rd.  From Hannes Frederic Sowa.
      
      11) Make ipv4/ipv6 fragmentation memory limits more reasonable in modern
          times, rearrange inet frag datastructures for better cacheline
          locality, and move more operations outside of locking.  From Jesper
          Dangaard Brouer.
      
      12) Instead of strict master <--> slave relationships, allow arbitrary
          scenerios with "upper device lists".  From Jiri Pirko.
      
      13) Improve rate limiting accuracy in TBF and act_police, also from Jiri
          Pirko.
      
      14) Add a BPF filter netfilter match target, from Willem de Bruijn.
      
      15) Orphan and delete a bunch of pre-historic networking drivers from
          Paul Gortmaker.
      
      16) Add TSO support for GRE tunnels, from Pravin B SHelar.  Although
          this still needs some minor bug fixing before it's %100 correct in
          all cases.
      
      17) Handle unresolved IPSEC states like ARP, with a resolution packet
          queue.  From Steffen Klassert.
      
      18) Remove TCP Appropriate Byte Count support (ABC), from Stephen
          Hemminger.  This was long overdue.
      
      19) Support SO_REUSEPORT, from Tom Herbert.
      
      20) Allow locking a socket BPF filter, so that it cannot change after a
          process drops capabilities.
      
      21) Add VLAN filtering to bridge, from Vlad Yasevich.
      
      22) Bring ipv6 on-par with ipv4 and do not cache neighbour entries in
          the ipv6 routes, from YOSHIFUJI Hideaki.
