       "A set of fixes for ARM platforms for 3.12.  Among them:
      
         - A fix for build breakage in the MTD subsystem for some PXA devices.
           David Woodhouse has this patch in his for-next branch but has not
           been responding to our requests to send it up so here it is.  I
           should have amended the commit message to describe the build
           failure for CONFIG_OF=n setups, but forgot and now it's down in the
           stack of commits.
      
         - Added device-tree for the BeagleBone Black.  Turns out people have
           been using the older "regualar" bone DT for the newer boards, and
           there's risk of damaging hardware that way.
      
         - Misc DT and regular fixes for OMAP.
      
         - Fix to make the ST-Ericsson "snowball" boards boot with
           multi_v7_defconfig, and enable one of the ST-E reference boards on
           the same config.
      
         - Kconfig cleanup for u300 to hide submenus when the platform isn't
           enabled.
      
         - Enable ARM_ATAG_DTB_COMPAT to let firmware override command line
           when booting with an appended devicetree on non-DT-enabled firmware
           (needed to boot snowball)"

      Pull networking fixes from David Miller:
      
       1) If the local_df boolean is set on an SKB we have to allocate a
          unique ID even if IP_DF is set in the ipv4 headers, from Ansis
          Atteka.
      
       2) Some fixups for the new chipset support that went into the sfc
          driver, from Ben Hutchings.
      
       3) Because SCTP bypasses a good chunk of, and actually duplicates, the
          logic of the ipv6 output path, some IPSEC things don't get done
          properly.  Integrate SCTP better into the ipv6 output path so that
          these problems are fixed and such issues don't get missed in the
          future either.  From Daniel Borkmann.
      
       4) Fix skge regressions added by the DMA mapping error return checking
          added in v3.10, from Mikulas Patocka.

       8) Prevent format-string injection into xen-netback driver, from Kees
          Cook.

          check for the right ETH_P_ARP protocol code.  From Sonic Zhang.

          Francois Romieu.
      
      11) Cure freezes due to recent changes in the rt2x00 wireless driver,
          from Stanislaw Gruszka.
      
      12) Don't do SPI transfers (which can sleep) in interrupt context in
          cw1200 driver, from Solomon Peachy.
      
      13) Fix LEDs handling bug in 5720 tg3 chips already handled for 5719.
          From Nithin Sujir.
      
      14) Make xen_netbk_count_skb_slots() count the actual number of slots
          that will be used, taking into consideration packing and other
          issues that the transmit path will run into.  From David Vrabel.
      
      15) Use the correct maximum age when calculating the bridge
          message_age_timer, from Chris Healy.

      20) Missing workqueue destroy in cxgb4 error handling, from Wei Yang.
      
      21) Internal switch not initialized properly in bgmac driver, from Rafał
          Miłecki.
      
      22) Netlink messages report wrong local and remote addresses in IPv6
          tunneling, from Ding Zhi.
      
      23) ICMP redirects should not generate socket errors in DCCP and SCTP.
          We're still working out how this should be handled for RAW and UDP
          sockets.  From Daniel Borkmann and Duan Jiong.
      
      24) We've had several bugs wherein the network namespace's loopback
          device gets accessed after it is free'd, NULL it out so that we can
          catch these problems more readily.  From Eric W Biederman.
      
      25) Fix regression in TCP RTO calculations, from Neal Cardwell.

      netconsole: fix a deadlock with rtnl and netconsole's mutex · c71380ff
      Nikolay Aleksandrov authored
      This bug was introduced by commit
      7a163bfb ("netconsole: avoid a crash with
      multiple sysfs writers"). In store_enabled() we have the following
      sequence: acquire nt->mutex then rtnl, but in the netconsole netdev
      notifier we have rtnl then nt->mutex effectively leading to a deadlock.
      The NULL pointer dereference that the above commit tries to fix is
      actually due to another bug in netpoll_cleanup(). This is fixed by dropping
      the mutex from the netdev notifier as it's already protected by rtnl.

      netpoll: fix NULL pointer dereference in netpoll_cleanup · d0fe8c88
      Nikolay Aleksandrov authored
      I've been hitting a NULL ptr deref while using netconsole because the
      np->dev check and the pointer manipulation in netpoll_cleanup are done
      without rtnl and the following sequence happens when having a netconsole
      over a vlan and we remove the vlan while disabling the netconsole:
      	CPU 1					CPU2
      					removes vlan and calls the notifier
      enters store_enabled(), calls
      netdev_cleanup which checks np->dev
      and then waits for rtnl
      					executes the netconsole netdev
      					release notifier making np->dev
      					== NULL and releases rtnl
      continues to dereference a member of
      np->dev which at this point is == NULL

      skge: fix broken driver · c194992c
      Mikulas Patocka authored
      The patch 136d8f37 broke the skge driver.
      Note this part of the patch:
      +               if (skge_rx_setup(skge, e, nskb, skge->rx_buf_size) < 0) {
      +                       dev_kfree_skb(nskb);
      +                       goto resubmit;
      +               }
      +
                      pci_unmap_single(skge->hw->pdev,
                                       dma_unmap_addr(e, mapaddr),
                                       dma_unmap_len(e, maplen),
                                       PCI_DMA_FROMDEVICE);
                      skb = e->skb;
                      prefetch(skb->data);
      -               skge_rx_setup(skge, e, nskb, skge->rx_buf_size);
      
      The function skge_rx_setup modifies e->skb to point to the new skb. Thus,
      after this change, the new buffer, not the old, is returned to the
      networking stack.
      
      This bug is present in kernels 3.11, 3.11.1 and 3.12-rc1. The patch should
      be queued for 3.11-stable.

      ip: generate unique IP identificator if local fragmentation is allowed · 703133de
      Ansis Atteka authored
      If local fragmentation is allowed, then ip_select_ident() and
      ip_select_ident_more() need to generate unique IDs to ensure
      correct defragmentation on the peer.
      
      For example, if IPsec (tunnel mode) has to encrypt large skbs
      that have local_df bit set, then all IP fragments that belonged
      to different ESP datagrams would have used the same identificator.
      If one of these IP fragments would get lost or reordered, then
      peer could possibly stitch together wrong IP fragments that did
      not belong to the same datagram. This would lead to a packet loss
      or data corruption.
