      Pull ARM SoC fixes from Arnd Bergmann:
       "This should be the last set of bugfixes for arm-soc in v4.9. None of
        these are critical regressions, but it would be nice to still get them
        merged.
      
         - On the Juno platform, the idle latency was described wrong, leading
           to suboptimal cpuidle tuning.
      
         - Also on the same platform, PCI I/O space was set up incorrectly and
           could not work.
      
         - On the sti platform, a syntactically incorrect DT entry caused
           warnings.
      
         - The newly added 'gr8' platform has somewhat confusing file names,
           which we rename for consistency"

          Johan Hovold.
      
       2) Fix race in packet_set_ring(), from Philip Pettersson.

          skb->protocol value as we enter the IPSEC engine and this causes all

      11) Buffer refcount problems in tun and macvtap on errors, from Jason
          Wang.
      
      12) We don't set Kconfig symbol DEFAULT_TCP_CONG properly when the user

      net: avoid signed overflows for SO_{SND|RCV}BUFFORCE · b98b0bc8
      Eric Dumazet authored
      CAP_NET_ADMIN users should not be allowed to set negative
      sk_sndbuf or sk_rcvbuf values, as it can lead to various memory
      corruptions, crashes, OOM...
      
      Note that before commit 82981930 ("net: cleanups in
      sock_setsockopt()"), the bug was even more serious, since SO_SNDBUF
      and SO_RCVBUF were vulnerable.
      
      This needs to be backported to all known linux kernels.
      
      Again, many thanks to syzkaller team for discovering this gem.

      geneve: avoid use-after-free of skb->data · 5b010147
      Sabrina Dubroca authored
      geneve{,6}_build_skb can end up doing a pskb_expand_head(), which
      makes the ip_hdr(skb) reference we stashed earlier stale. Since it's
      only needed as an argument to ip_tunnel_ecn_encap(), move this
      directly in the function call.

      tipc: check minimum bearer MTU · 3de81b75
      Michal Kubeček authored
      Qian Zhang (张谦) reported a potential socket buffer overflow in
      tipc_msg_build() which is also known as CVE-2016-8632: due to
      insufficient checks, a buffer overflow can occur if MTU is too short for
      even tipc headers. As anyone can set device MTU in a user/net namespace,
      this issue can be abused by a regular user.
      
      As agreed in the discussion on Ben Hutchings' original patch, we should
      check the MTU at the moment a bearer is attached rather than for each
      processed packet. We also need to repeat the check when bearer MTU is
      adjusted to new device MTU. UDP case also needs a check to avoid
      overflow when calculating bearer MTU.

      sh_eth: remove unchecked interrupts for RZ/A1 · 33d446db
      Chris Brandt authored
      When streaming a lot of data and the RZ/A1 can't keep up, some status bits
      will get set that are not being checked or cleared which cause the

      __bcmgenet_tx_reclaim() and bcmgenet_free_rx_buffers() are not using the
      same struct device during unmap that was used for the map operation,
      which makes DMA-API debugging warn about it. Fix this by always using
      &priv->pdev->dev throughout the driver, using an identical device
      reference for all map/unmap calls.

      Merge branch 'mvneta-64bit' · 4f4f907a
      David S. Miller authored
      Gregory CLEMENT says:
      
      ====================
      Support Armada 37xx SoC (ARMv8 64-bits) in mvneta driver
      
      The Armada 37xx is a new ARMv8 SoC from Marvell using same network
      controller as the older Armada 370/38x/XP SoCs. This series adapts the
      driver in order to be able to use it on this new SoC. The main changes
      are:
      
      - 64-bits support: the first patches allow using the driver on a 64-bit
        architecture.
      
      - MBUS support: the mbus configuration is different on Armada 37xx
        from the older SoCs.
      
      - per cpu interrupt: Armada 37xx do not support per cpu interrupt for
        the NETA IP, the non-per-CPU behavior was added back.
      
      The first patch is an optimization in the rx path in swbm mode.
      The second patch remove unnecessary allocation for HWBM.
      The first item is solved by patches 4 and 5.
      The 2 last items are solved by patch 6.
      In patch 7 the dt support is added.
      
      Beside Armada 37xx, this series have been again tested on Armada XP
      and Armada 38x (with Hardware Buffer Management and with Software
      Buffer Management).
      
      This is the 6th version of the series:
      - 1st version:
      http://lists.infradead.org/pipermail/linux-arm-kernel/2016-November/469588.html
      
      - 2nd version:
      http://lists.infradead.org/pipermail/linux-arm-kernel/2016-November/470476.html
      
      - 3rd version:
      http://lists.infradead.org/pipermail/linux-arm-kernel/2016-November/470901.html
      
      - 4th version:
      http://lists.infradead.org/pipermail/linux-arm-kernel/2016-November/471039.html
      
      - 5th version:
      http://lists.infradead.org/pipermail/linux-arm-kernel/2016-November/471478.html
      
      Changelog:
      v5 -> v6:
       - Added Tested-by from  Marcin Wojtas on the series
       - Added Reviewed-by from Jisheng Zhang on patch 3
       - Fix eth1 phy mode for Armada 3720 DB board on patch 7
      
      v4 -> v5:
       - remove unnecessary cast in patch 3
      
      v3 -> v4:
       - Adding new patch: "net: mvneta: do not allocate buffer in rxq init
         with HWBM"
      
       - Simplify the HWBM case in patch 3 as suggested by Marcin
      
      v2 -> v3:
       - Adding patch 1 "Optimize rx path for small frame"
      
       - Fix the kbuild error by moving the "phys_addr += pp->rx_offset_correction;"
        line from patch 2 to patch 3 where rx_offset_correction is introduced.
      
       - Move the memory allocation of the buf_virt_addr of the rxq to be
         called by the probe function in order to avoid a memory leak.
