       "This set includes adding support for Neon acceleration of RAID6 XOR
        code from Ard Biesheuvel, cache flushing and barrier updates from Will
        Deacon, and a cleanup to the ARM debug code which reduces the amount

        A few other cleanups, such as constifying the machine descriptors
        which already shouldn't be written to, cleaning up the printing of the
        L2 cache size"

      net: stmmac: fix bad merge conflict resolution · 356f9e74
      Olof Johansson 提交于
      Merge commit 06c54055 did a bad conflict resolution accidentally
      leaving out a closing brace.  Add it back.
      
      This breaks a handful of defconfigs on ARM, so it'd be good to see it
      applied pretty quickly.

      Pull networking changes from David Miller:
       "Noteworthy changes this time around:
      
         1) Multicast rejoin support for team driver, from Jiri Pirko.
      
         2) Centralize and simplify TCP RTT measurement handling in order to
            reduce the impact of bad RTO seeding from SYN/ACKs.  Also, when
            both timestamps and local RTT measurements are available prefer
            the later because there are broken middleware devices which
            scramble the timestamp.
      
            From Yuchung Cheng.
      
         3) Add TCP_NOTSENT_LOWAT socket option to limit the amount of kernel
            memory consumed to queue up unsend user data.  From Eric Dumazet.
      
         4) Add a "physical port ID" abstraction for network devices, from
            Jiri Pirko.
      
         5) Add a "suppress" operation to influence fib_rules lookups, from
            Stefan Tomanek.
      
         6) Add a networking development FAQ, from Paul Gortmaker.
      
         7) Extend the information provided by tcp_probe and add ipv6 support,
            from Daniel Borkmann.
      
         8) Use RCU locking more extensively in openvswitch data paths, from
            Pravin B Shelar.
      
         9) Add SCTP support to openvswitch, from Joe Stringer.
      
        10) Add EF10 chip support to SFC driver, from Ben Hutchings.
      
        11) Add new SYNPROXY netfilter target, from Patrick McHardy.
      
        12) Compute a rate approximation for sending in TCP sockets, and use
            this to more intelligently coalesce TSO frames.  Furthermore, add
            a new packet scheduler which takes advantage of this estimate when
            available.  From Eric Dumazet.
      
        13) Allow AF_PACKET fanouts with random selection, from Daniel
            Borkmann.

      openvswitch: Fix alignment of struct sw_flow_key. · 0d40f75b
      Jesse Gross 提交于
      sw_flow_key alignment was declared as " __aligned(__alignof__(long))".
      However, this breaks on the m68k architecture where long is 32 bit in
      size but 16 bit aligned by default. This aligns to the size of a long to
      ensure that we can always do comparsions in full long-sized chunks. It
      also adds an additional build check to catch any reduction in alignment.

      This commit implements the ->ndo_do_ioctl() operation so that the
      PHY-related ioctl() calls can work from userspace, which allows
      applications like mii-tool or mii-diag to do their job.

      net: mvneta: properly disable HW PHY polling and ensure adjust_link() works · 71408602
      Thomas Petazzoni 提交于
      This commit fixes a long-standing bug that has been reported by many
      users: on some Armada 370 platforms, only the network interface that
      has been used in U-Boot to tftp the kernel works properly in
      Linux. The other network interfaces can see a 'link up', but are
      unable to transmit data. The reports were generally made on the Armada
      370-based Mirabox, but have also been given on the Armada 370-RD
      board.
      
      The network MAC in the Armada 370/XP (supported by the mvneta driver
      in Linux) has a functionality that allows it to continuously poll the
      PHY and directly update the MAC configuration accordingly (speed,
      duplex, etc.). The very first versions of the driver submitted for
      review were using this hardware mechanism, but due to this, the driver
      was not integrated with the kernel phylib. Following reviews, the
      driver was changed to use the phylib, and therefore a software based
      polling. In software based polling, Linux regularly talks to the PHY
      over the MDIO bus, and sees if the link status has changed. If it's
      the case then the adjust_link() callback of the driver is called to
      update the MAC configuration accordingly.
      
      However, it turns out that the adjust_link() callback was not
      configuring the hardware in a completely correct way: while it was
      setting the speed and duplex bits correctly, it wasn't telling the
      hardware to actually take into account those bits rather than what the
      hardware-based PHY polling mechanism has concluded. So, in fact the
      adjust_link() callback was basically a no-op.
      
      However, the network happened to be working because on the network
      interfaces used by U-Boot for tftp on Armada 370 platforms because the
      hardware PHY polling was enabled by the bootloader, and left enabled
      by Linux. However, the second network interface not used for tftp (or
      both network interfaces if the kernel is loaded from USB, NAND or SD
      card) didn't had the hardware PHY polling enabled.
      
      This patch fixes this situation by:
      
       (1) Making sure that the hardware PHY polling is disabled by clearing
           the MVNETA_PHY_POLLING_ENABLE bit in the MVNETA_UNIT_CONTROL
           register in the driver ->probe() function.
      
       (2) Making sure that the duplex and speed selections made by the
           adjust_link() callback are taken into account by clearing the
           MVNETA_GMAC_AN_SPEED_EN and MVNETA_GMAC_AN_DUPLEX_EN bits in the
           MVNETA_GMAC_AUTONEG_CONFIG register.
      
      This patch has been tested on Armada 370 Mirabox, and now both network
      interfaces are usable after boot.

      ethernet/arc/arc_emac: Fix huge delays in large file copies · 27082ee1
      Vineet Gupta 提交于
      copying large files to a NFS mounted host was taking absurdly large
      time.
      
      Turns out that TX BD reclaim had a sublte bug.
      
      Loop starts off from @txbd_dirty cursor and stops when it hits a BD
      still in use by controller. However when it stops it needs to keep the
      cursor at that very BD to resume scanning in next iteration. However it
      was erroneously incrementing the cursor, causing the next scan(s) to
      fail too, unless the BD chain was completely drained out.

      qlcnic: use standard NAPI weights · df95fc44
      Michal Schmidt 提交于
      Since commit 82dc3c63 ("net: introduce NAPI_POLL_WEIGHT")
      netif_napi_add() produces an error message if a NAPI poll weight
      greater than 64 is requested.
      
      qlcnic requests the weight as large as 256 for some of its rings, and
      smaller values for other rings. For instance in qlcnic_82xx_napi_add()
      I think the intention was to give the tx+rx ring a bigger weight than
      to rx-only rings, but it's actually doing the opposite. So I'm assuming
      the weights do not really matter much.
      
      Just use the standard NAPI weights for all rings.

      ipv6:introduce function to find route for redirect · b55b76b2
      Duan Jiong 提交于
      RFC 4861 says that the IP source address of the Redirect is the
      same as the current first-hop router for the specified ICMP
      Destination Address, so the gateway should be taken into
      consideration when we find the route for redirect.
      
      There was once a check in commit
      a6279458 ("NDISC: Search over
      all possible rules on receipt of redirect.") and the check
      went away in commit b94f1c09
      ("ipv6: Use icmpv6_notify() to propagate redirect, instead of
      rt6_redirect()").
      
      The bug is only "exploitable" on layer-2 because the source
      address of the redirect is checked to be a valid link-local
      address but it makes spoofing a lot easier in the same L2
      domain nonetheless.

      vxlan: Notify drivers for listening UDP port changes · 53cf5275
      Joseph Gasparakis 提交于
      This patch adds two more ndo ops: ndo_add_rx_vxlan_port() and
      ndo_del_rx_vxlan_port().
      
      Drivers can get notifications through the above functions about changes
      of the UDP listening port of VXLAN. Also, when physical ports come up,
      now they can call vxlan_get_rx_port() in order to obtain the port number(s)
      of the existing VXLAN interface in case they already up before them.
      
      This information about the listening UDP port would be used for VXLAN
      related offloads.
      
      A big thank you to John Fastabend (john.r.fastabend@intel.com) for his
      input and his suggestions on this patch set.

      Merge tag 'fbdev-3.12-omap-legacy-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux
      
      Pull OMAP specific fbdev changes from Tomi Valkeinen:
       "I've got this pull request separate from the main fbdev pull request,
        as this contains a bunch of OMAP board file changes and thus could
        possibly be rejected in case of bad conflicts.
      
        The removal of the old display drivers depend on the board file
        changes, so Tony Lindgren suggested taking them together via fbdev
        tree.  These are in linux-next, and also Tony didn't see any conflicts
        with any of the branches he had, so they should go in clean.
      
         - Change the OMAP board files to use the new OMAP display drivers
      
         - Remove all the old drivers, and the related auxiliary code"
