      myri10ge: Add vlan rx for better GRO perf. · 1b4c44e6
      Andrew Gallatin authored
      Unlike LRO, GRO requires that vlan tags be removed before
      aggregation can occur.  Since the myri10ge NIC does not support
      hardware vlan tag offload, we must remove the tag in the driver
      to achieve performance comparable to LRO for vlan tagged frames.
      Thanks to Eric Duzamet for his help simplifying the original patch.

      myri10ge: Convert from LRO to GRO · 4ca3221f
      Andrew Gallatin authored
      Convert myri10ge from LRO to GRO, and simplify the driver by removing
      various LRO-related code which is no longer needed including
      ndo_fix_features op, custom skb building from frags, and LRO
      header parsing.

      rtnelink: remove unused parameter from rtnl_create_link(). · c0713563
      Rami Rosen authored
      This patch removes an unused parameter (src_net) from rtnl_create_link()
      method and from the method single invocation, in veth.
      This parameter was used in the past when calling
      ops->get_tx_queues(src_net, tb) in rtnl_create_link().
      The get_tx_queues() member of rtnl_link_ops was replaced by two methods,
      get_num_tx_queues() and get_num_rx_queues(), which do not get any
      parameter. This was done in commit d40156aa by
      Jiri Pirko ("rtnl: allow to specify different num for rx and tx queue count").

        superfluous typecasting from 'u64' to 'unsigned long *'.
      - Convert superfluous atomic bitops to non atomic bitops.  The bitmap
        is allocated on the stack and it is not accessed by any other threads,
        so using atomic bitops is not necessary.
      - Use find_next_zero_bit and find_next_zero_bit instead of calling

      8021q: fix vlan device to inherit the unicast filtering capability flag · 6e22ce2c
      Yi Zou authored
      This bug is observed on running FCoE over a VLAN device associated w/
      a real device that has IFF_UNICAST_FLT set since FCoE would add unicast
      address such as FLOGI MAC to the VLAN interface that FCoE is on. Since
      currently, VLAN device is not inheriting the IFF_UNICAST_FLT flag from the
      parent real device even though the real device is capable of doing unicast
      filtering. This forces the VLAN device and its real device go to promiscuous
      mode unnecessarily even the added address is actually being added to the
      available unicast filter table in real device.

      bonding: delete migrated IP addresses from the rlb hash table · e53665c6
      Jiri Bohac authored
      Bonding in balance-alb mode records information from ARP packets
      passing through the bond in a hash table (rx_hashtbl).
      At certain situations (e.g. link change of a slave),
      rlb_update_rx_clients() will send out ARP packets to update ARP
      caches of other hosts on the network to achieve RX load
      The problem is that once an IP address is recorded in the hash
      table, it stays there indefinitely. If this IP address is
      migrated to a different host in the network, bonding still sends
      out ARP packets that poison other systems' ARP caches with
      invalid information.
      This patch solves this by looking at all incoming ARP packets,
      and checking if the source IP address is one of the source
      addresses stored in the rx_hashtbl. If it is, but the MAC
      addresses differ, the corresponding hash table entries are
      removed. Thus, when an IP address is migrated, the first ARP
      broadcast by its new owner will purge the offending entries of
      The hash table is hashed by ip_dst. To be able to do the above
      check efficiently (not walking the whole hash table), we need a
      reverse mapping (by ip_src).
      I added three new members in struct rlb_client_info:
         rx_hashtbl[x].src_first will point to the start of a list of
            entries for which hash(ip_src) == x.
         The list is linked with src_next and src_prev.
      When an incoming ARP packet arrives at rlb_arp_recv()
      rlb_purge_src_ip() can quickly walk only the entries on the
      corresponding lists, i.e. the entries that are likely to contain
      the offending IP address.
      To avoid confusion, I renamed these existing fields of struct
      	next -> used_next
      	prev -> used_prev
      	rx_hashtbl_head -> rx_hashtbl_used_head
      (The current linked list is _not_ a list of hash table
      entries with colliding ip_dst. It's a list of entries that are
      being used; its purpose is to avoid walking the whole hash table
      when looking for used entries.)

      bonding: rlb mode of bond should not alter ARP originating via bridge · 567b871e
      zheng.li authored
      Do not modify or load balance ARP packets passing through balance-alb
      mode (wherein the ARP did not originate locally, and arrived via a bridge).
      Modifying pass-through ARP replies causes an incorrect MAC address
      to be placed into the ARP packet, rendering peers unable to communicate
      with the actual destination from which the ARP reply originated.
      Load balancing pass-through ARP requests causes an entry to be
      created for the peer in the rlb table, and bond_alb_monitor will
      occasionally issue ARP updates to all peers in the table instrucing them
      as to which MAC address they should communicate with; this occurs when
      some event sets rx_ntt.  In the bridged case, however, the MAC address
      used for the update would be the MAC of the slave, not the actual source
      MAC of the originating destination.  This would render peers unable to
      communicate with the destinations beyond the bridge.

      This series of improvements for 3.8/net-next contains four components:
       * Support for modifying IPv6 headers
       * Support for matching and setting skb->mark for better integration with
         things like iptables
       * Ability to recognize the EtherType for RARP packets
       * Two small performance enhancements
      The movement of ipv6_find_hdr() into exthdrs_core.c causes two small merge
      conflicts.  I left it as is but can do the merge if you want.  The conflicts
       * ipv6_find_hdr() and ipv6_find_tlv() were both moved to the bottom of
         exthdrs_core.c.  Both should stay.
       * A new use of ipv6_find_hdr() was added to net/netfilter/ipvs/ip_vs_core.c
         after this patch.  The IPVS user has two instances of the old constant
         name IP6T_FH_F_FRAG which has been renamed to IP6_FH_F_FRAG.

      Pull networking fixes from David Miller:
       "Some more fixes trickled in over the past few days:
         1) PIM device names can overflow the IFNAMSIZ buffer unless we
            properly limit the allowed indexes, fix from Eric Dumazet.
         2) Under heavy load we can OOPS in icmp reply processing due to an
            unchecked inet_putpeer() call.  Fix from Neal Cardwell.
         3) SCTP round trip calculations need to use 64-bit math to avoid
            overflows, fix from Schoch Christian.
         4) Fix a memory leak and an error return flub in SCTP and IRDA
            triggerable by userspace.  Fix from Tommi Rantala and found by the
            syscall fuzzer (trinity).
         5) MLX4 driver gives bogus size to memcpy() call, fix from Amir
         6) Fix length calculation in VHOST descriptor translation, from
            Michael S Tsirkin.
         7) Ambassador ATM driver loops forever while loading firmware, fix
            from Dan Carpenter.
         8) Over MTU packets in openvswitch warn about wrong device, fix from
            Jesse Gross.
         9) Netfilter IPSET's netlink code can overrun a string buffer because
            it's not properly limited to IFNAMSIZ.  Fix from Florian Westphal.
        10) PCAN USB driver sets wrong timestamp in SKB, from Oliver Hartkopp.
        11) Make sure the RX ifindex always has a valid value in the CAN BCM
            driver, even if we haven't received a frame yet.  Fix also from
            Oliver Hartkopp."

      John W. Linville says:
      This pull request is intended for the 3.8 stream.  It is a bit large
      -- I guess Thanksgiving got me off track!  At least the code got to
      spend some time in linux-next... :-)
      This includes the usual batch of pulls for Bluetooth, NFC, and mac80211
      as well as iwlwifi.  Also here is an ath6kl pull, and a new driver
      in the rtlwifi family.  The brcmfmac, brcmsmac, ath9k, and mwl8k get
      their usual levels of attention, and a handful of other updates tag
      along as well.
      For more detail on the pulls, please see below...
      On Bluetooth, Gustavo says:
      "Another set of patches for integration in wireless-next. There are two big set
      of changes in it: Andrei Emeltchenko and Mat Martineau added more patches
      towards a full Bluetooth High Speed support and Johan Hedberg improve the
      single mode support for Bluetooth dongles. Apart from that we have small fixes
      and improvements."
      "A few patches to 3.8. The majority of the work here is from Andrei on the High
      Speed support. Other than that Johan added support for setting LE advertising
      data. The rest are fixes and clean ups and small improvements like support for
      a new broadcom hardware."
      On mac80211, Johannes says:
      "This is for mac80211, for -next (3.8). Plenty of changes, as you can see
      below. Some fixes for previous changes like the export.h include, the
      beacon listener fix from Ben Greear, etc. Overall, no exciting new
      features, though hwsim does gain channel context support for people to
      try it out and look at."
      "This one contains the mac80211-next material. Apart from a few small new
      features and cleanups I have two fixes for the channel context code. The
      RX_END timestamp support will probably be reworked again as Simon Barber
      noted the calculations weren't really valid, but the discussions there
      are still going on and it's better than what we had before."
      "Please pull (see below) to get the following changes:
       * a fix & a debug aid in IBSS from Antonio,
       * mesh cleanups from Marco,
       * a few bugfixes for some of my previous patches from Arend and myself,
       * and the big initial VHT support patchset"
      And on iwlwifi, Johannes says:
      "In addition to the previous four patches that I'm not resending,
      we have a number of cleanups, message reduction, firmware error
      handling improvements (yes yes... we need to fix them instead)
      and various other small things all over."
      "In his quest to try to understand the current iwlwifi problems (like
      stuck queues etc.) Emmanuel has first cleaned up the PCIe code, I'm
      including his changes in this pull request. Other than that I only have
      a small cleanup from Sachin Kamat to remove a duplicate include and a
      bugfix to turn off MFP if software crypto is enabled, but this isn't
      really interesting as MFP isn't supported right now anyway."
      On NFC, Samuel says:
      "With this one we have:
      - A few HCI improvements in preparation for an upcoming HCI chipset support.
      - A pn544 code cleanup after the old driver was removed.
      - An LLCP improvement for notifying user space when one peer stops ACKing I
      On ath6kl, Kalle says:
      "Major changes this time are firmware recover support to gracefully
      handle if firmware crashes, support for changing regulatory domain and
      support for new ar6004 hardware revision 1.4. Otherwise there are just
      smaller fixes or cleanups from different people."
      Thats about it... :-)  Please let me know if there are problems!

      openvswitch: Use RCU callback when detaching netdevices. · 92eb1d47
      Jesse Gross authored
      Currently, each time a device is detached from an OVS datapath
      we call synchronize RCU before freeing associated data structures.
      However, if a bridge is deleted (which detaches all ports) when
      many devices are connected then there can be a long delay.  This
      switches to use call_rcu() to group the cost together.
