      Pull networking updates from David Miller:
       1) New offloading infrastructure and example 'rocker' driver for
          offloading of switching and routing to hardware.
          This work was done by a large group of dedicated individuals, not
          limited to: Scott Feldman, Jiri Pirko, Thomas Graf, John Fastabend,
          Jamal Hadi Salim, Andy Gospodarek, Florian Fainelli, Roopa Prabhu
       2) Start making the networking operate on IOV iterators instead of
          modifying iov objects in-situ during transfers.  Thanks to Al Viro
          and Herbert Xu.
       3) A set of new netlink interfaces for the TIPC stack, from Richard
       4) Remove unnecessary looping during ipv6 routing lookups, from Martin
          KaFai Lau.
       5) Add PAUSE frame generation support to gianfar driver, from Matei
       6) Allow for larger reordering levels in TCP, which are easily
          achievable in the real world right now, from Eric Dumazet.
       7) Add a variable of napi_schedule that doesn't need to disable cpu
          interrupts, from Eric Dumazet.
       8) Use a doubly linked list to optimize neigh_parms_release(), from
          Nicolas Dichtel.
       9) Various enhancements to the kernel BPF verifier, and allow eBPF
          programs to actually be attached to sockets.  From Alexei
      10) Support TSO/LSO in sunvnet driver, from David L Stevens.
      11) Allow controlling ECN usage via routing metrics, from Florian
      12) Remote checksum offload, from Tom Herbert.

      15) Support wildcard tunnel endpoints in ipv6 tunnels, from Steffen
      16) Do gro flushes on a per-device basis using a timer, from Eric
          Dumazet.  This tries to resolve the conflicting goals between the
          desired handling of bulk vs.  RPC-like traffic.
      17) Allow userspace to ask for the CPU upon what a packet was
          received/steered, via SO_INCOMING_CPU.  From Eric Dumazet.
      18) Limit GSO packets to half the current congestion window, from Eric

      Pull sound updates from Takashi Iwai:
       "This became a fairly large pull request.  In addition to the usual
        driver updates / fixes, there have been a high amount of cleanups in
        ASoC area, as well as control API helpers and kernel documentations
        fixes touching through the whole tree.
        In the driver side, the biggest changes are the support for new Intel
        SoC found on new x86 machines, and the updates of FireWire dice and
        oxfw drivers.
        Some remarkable items are below:
        ALSA core:
         - PCM mmap code cleanup, removal of arch-dependent codes
         - PCM xrun injection support
         - PCM hwptr tracepoint support
         - Refactoring of snd_pcm_action(), simplification of PCM locking
         - Robustified sequecner auto-load functionality
         - New control API helpers and lots of cleanups along with them
         - Lots of kerneldoc fixes and cleanups
         - The mixer resume code was largely rewritten, and the devices with
           quirks are resumed properly.
         - New hardware support: Focusrite Scarlett, Digidesign Mbox1,
           Denon/Marantz DACs, Zoom R16/24
         - DICE driver updates with better duplex and sync support, including
           MIDI support
         - New OXFW driver for Oxford Semiconductor FW970/971 chipset,
           including the previous LaCie Speakers device.  Fullduplex and MIDI
           support included as well as DICE driver.
         - Refactoring the driver-caps quirk handling in snd-hda-intel
         - More consistent control names representing the topology better
         - Fixups: HP mute LED with ALC268 codec, Ideapad S210 built-in mic
           fix, ASUS Z99He laptop EAPD
         - Conversion of AC'97 drivers to use regmap, bringing us closer to
           the removal of the ASoC level I/O code
         - Clean up a lot of old drivers that were open coding things that
           have subsequently been implemented in the core
         - Some DAPM performance improvements
         - Removal of the now seldom used CODEC mutex
         - Lots of updates for the newer Intel SoC support, including support
           for the DSP and some Cherrytrail and Braswell machine drivers
         - Support for Samsung boards using rt5631 as the CODEC
         - Removal of the obsolete AFEB9260 machine driver
         - Driver support for the TI TS3A227E headset driver used in some
         - ASIHPI driver update and cleanups
         - Lots of dev_*() printk conversions
         - Lots of trivial cleanups for the codes spotted by Coccinelle"

      Pull devicetree changes from Grant Likely:
       "Lots of activity in the devicetree code for v3.18.  Most of it is
        related to getting all of the overlay support code in place, but there
        are other important things in there.
         - OF_RECONFIG notifiers for SPI, I2C and Platform devices.  Those
           subsystems can now respond to live changes to the device tree.
         - CONFIG_OF_OVERLAY method for applying live changes to the device
         - Removal of the of_allnodes list.  This used to be used to iterate
           over all the nodes in the device tree, but it is unnecessary
           because the same thing can be done by iterating over the list of
           child pointers.  Getting rid of of_allnodes saves some memory and
           avoids the possibility of of_allnodes being sorted differently from
           the child lists.
         - Support for retrieving original DTB blob via sysfs.  Needed by
         - More unittests
         - Documentation and minor bug fixes"

      Fix race condition between vxlan_sock_add and vxlan_sock_release · 00c83b01
      Marcelo Leitner authored
      Currently, when trying to reuse a socket, vxlan_sock_add will grab
      vn->sock_lock, locate a reusable socket, inc refcount and release
      But vxlan_sock_release() will first decrement refcount, and then grab
      that lock. refcnt operations are atomic but as currently we have
      deferred works which hold vs->refcnt each, this might happen, leading to
      a use after free (specially after vxlan_igmp_leave):
        CPU 1                            CPU 2
      deferred work                    vxlan_sock_add
        ...                              ...
                                         vs = vxlan_find_sock();
          dec vs->refcnt, reaches 0
                                         vxlan_sock_hold(vs), refcnt=1
      So when we look for a reusable socket, we check if it wasn't freed
      already before reusing it.

      Or Gerlitz says:
      mlx4 driver update
      This series from Matan, Jenny, Dotan and myself is mostly about adding
      support to a new performance optimized flow steering mode (patches 4-10).
      The 1st two patches are small fixes (one for VXLAN and one for SRIOV),
      and the third patch is a fix to avoid hard-lockup situation when many
      (hunderds) processes holding user-space QPs/CQs get events.
      Matan and Or.

      net/mlx4: Add support for A0 steering · 7d077cd3
      Matan Barak authored
      Add the required firmware commands for A0 steering and a way to enable
      that. The firmware support focuses on INIT_HCA, QUERY_HCA, QUERY_PORT,
      QUERY_DEV_CAP and QUERY_FUNC_CAP commands. Those commands are used
      to configure and query the device.
      The different A0 DMFS (steering) modes are:
      Static - optimized performance, but flow steering rules are
      limited. This mode should be choosed explicitly by the user
      in order to be used.
      Dynamic - this mode should be explicitly choosed by the user.
      In this mode, the FW works in optimized steering mode as long as
      it can and afterwards automatically drops to classic (full) DMFS.
      Disable - this mode should be explicitly choosed by the user.
      The user instructs the system not to use optimized steering, even if
      the FW supports Dynamic A0 DMFS (and thus will be able to use optimized
      steering in Default A0 DMFS mode).
      Default - this mode is implicitly choosed. In this mode, if the FW
      supports Dynamic A0 DMFS, it'll work in this mode. Otherwise, it'll
      work at Disable A0 DMFS mode.
      Under SRIOV configuration, when the A0 steering mode is enabled,
      older guest VF drivers who aren't using the RX QP allocation flag
      (MLX4_RESERVE_A0_QP) will get a QP from the general range and
      fail when attempting to register a steering rule. To avoid that,
      the PF context behaviour is changed once on A0 static mode, to
      require support for the allocation flag in VF drivers too.
      In order to enable A0 steering, we use log_num_mgm_entry_size param.
      If the value of the parameter is not positive, we treat the absolute
      value of log_num_mgm_entry_size as a bit field. Setting bit 2 of this
      bit field enables static A0 steering.

      net/mlx4: Refactor QUERY_PORT · 431df8c7
      Matan Barak authored
      Currently QUERY_PORT is done as a part of QUERY_DEV_CAP firmware command.
      Since we would like to use it without querying all device capabilities,
      extract this part to be a function of its own.

      net/mlx4_core: Add explicit error message when rule doesn't meet configuration · 579d059b
      Matan Barak authored
      When a given flow steering rule is invalid in respect to the current
      steering configuration, print the correct error message to the system log.
