      Pull networking fixes from David Miller:
       "Mostly these are fixes for fallout due to merge window changes, as
        well as cures for problems that have been with us for a much longer
        period of time"
      
       1) Johannes Berg noticed two major deficiencies in our genetlink
          registration.  Some genetlink protocols we passing in constant
          counts for their ops array rather than something like
          ARRAY_SIZE(ops) or similar.  Also, some genetlink protocols were
          using fixed IDs for their multicast groups.
      
          We have to retain these fixed IDs to keep existing userland tools
          working, but reserve them so that other multicast groups used by
          other protocols can not possibly conflict.
      
          In dealing with these two problems, we actually now use less state
          management for genetlink operations and multicast groups.
      
       2) When configuring interface hardware timestamping, fix several
          drivers that simply do not validate that the hwtstamp_config value
          is one the driver actually supports.  From Ben Hutchings.
      
       3) Invalid memory references in mwifiex driver, from Amitkumar Karwar.
      
       4) In dev_forward_skb(), set the skb->protocol in the right order
          relative to skb_scrub_packet().  From Alexei Starovoitov.
      
       5) Bridge erroneously fails to use the proper wrapper functions to make
          calls to netdev_ops->ndo_vlan_rx_{add,kill}_vid.  Fix from Toshiaki
          Makita.
      
       6) When detaching a bridge port, make sure to flush all VLAN IDs to
          prevent them from leaking, also from Toshiaki Makita.
      
       7) Put in a compromise for TCP Small Queues so that deep queued devices
          that delay TX reclaim non-trivially don't have such a performance
          decrease.  One particularly problematic area is 802.11 AMPDU in
          wireless.  From Eric Dumazet.
      
       8) Fix crashes in tcp_fastopen_cache_get(), we can see NULL socket dsts
          here.  Fix from Eric Dumzaet, reported by Dave Jones.
      
       9) Fix use after free in ipv6 SIT driver, from Willem de Bruijn.
      
      10) When computing mergeable buffer sizes, virtio-net fails to take the
          virtio-net header into account.  From Michael Dalton.
      
      11) Fix seqlock deadlock in ip4_datagram_connect() wrt.  statistic
          bumping, this one has been with us for a while.  From Eric Dumazet.
      
      12) Fix NULL deref in the new TIPC fragmentation handling, from Erik
          Hugne.
      
      13) 6lowpan bit used for traffic classification was wrong, from Jukka
          Rissanen.
      
      14) macvlan has the same issue as normal vlans did wrt.  propagating LRO
          disabling down to the real device, fix it the same way.  From Michal
          Kubecek.
      
      15) CPSW driver needs to soft reset all slaves during suspend, from
          Daniel Mack.
      
      16) Fix small frame pacing in FQ packet scheduler, from Eric Dumazet.
      
      17) The xen-netfront RX buffer refill timer isn't properly scheduled on
          partial RX allocation success, from Ma JieYue.
      
      18) When ipv6 ping protocol support was added, the AF_INET6 protocol
          initialization cleanup path on failure was borked a little.  Fix
          from Vlad Yasevich.
      
      19) If a socket disconnects during a read/recvmsg/recvfrom/etc that
          blocks we can do the wrong thing with the msg_name we write back to
          userspace.  From Hannes Frederic Sowa.  There is another fix in the
          works from Hannes which will prevent future problems of this nature.
      
      20) Fix route leak in VTI tunnel transmit, from Fan Du.

      genetlink: clean up multicast group APIs
      
      The generic netlink multicast group registration doesn't have to
      be dynamic, and can thus be simplified just like I did with the
      ops. This removes some complexity in registration code.
      
      Additionally, two users of generic netlink already use multicast
      groups in a wrong way, add workarounds for those two to keep the
      userspace API working, but at the same time make them not clash
      with other users of multicast groups as might happen now.
      
      While making it all a bit easier, also prevent such abuse by adding
      checks to the APIs so each family can only use the groups it owns.

      genetlink: make multicast groups const, prevent abuse · 2a94fe48
      Johannes Berg authored
      Register generic netlink multicast groups as an array with
      the family and give them contiguous group IDs. Then instead
      of passing the global group ID to the various functions that
      send messages, pass the ID relative to the family - for most
      families that's just 0 because the only have one group.
      
      This avoids the list_head and ID in each group, adding a new
      field for the mcast group ID offset to the family.
      
      At the same time, this allows us to prevent abusing groups
      again like the quota and dropmon code did, since we can now
      check that a family only uses a group it owns.

      Johannes Berg authored
      The quota code is abusing the genetlink API and is using
      its family ID as the multicast group ID, which is invalid
      and may belong to somebody else (and likely will.)
      
      Make the quota code use the correct API, but since this
      is already used as-is by userspace, reserve a family ID
      for this code and also reserve that group ID to not break
      userspace assumptions.

      code to preserve the userspace API. Since drop monitor can
      be a module, don't clear the bit for it on unregistration.

      genetlink: only pass array to genl_register_family_with_ops() · c53ed742
      Johannes Berg authored
      As suggested by David Miller, make genl_register_family_with_ops()
      a macro and pass only the array, evaluating ARRAY_SIZE() in the
      macro, this is a little safer.
      
      The openvswitch has some indirection, assing ops/n_ops directly in
      that code. This might ultimately just assign the pointers in the
      family initializations, saving the struct genl_family_and_ops and
      code (once mcast groups are handled differently.)

      tcp: don't update snd_nxt, when a socket is switched from repair mode · dbde4979
      Andrey Vagin authored
      snd_nxt must be updated synchronously with sk_send_head.  Otherwise
      tp->packets_out may be updated incorrectly, what may bring a kernel panic.
      
      Here is a kernel panic from my host.
      [  103.043194] BUG: unable to handle kernel NULL pointer dereference at 0000000000000048
      [  103.044025] IP: [<ffffffff815aaaaf>] tcp_rearm_rto+0xcf/0x150
      ...
      [  146.301158] Call Trace:
      [  146.301158]  [<ffffffff815ab7f0>] tcp_ack+0xcc0/0x12c0
      
      Before this panic a tcp socket was restored. This socket had sent and
      unsent data in the write queue. Sent data was restored in repair mode,
      then the socket was switched from reapair mode and unsent data was
      restored. After that the socket was switched back into repair mode.
      
      In that moment we had a socket where write queue looks like this:
      snd_una    snd_nxt   write_seq
         |_________|________|
                   |
      	  sk_send_head
      
      After a second switching from repair mode the state of socket was
      changed:
      
      snd_una          snd_nxt, write_seq
         |_________ ________|
                   |
      	  sk_send_head
      
      This state is inconsistent, because snd_nxt and sk_send_head are not
      synchronized.
      
      Bellow you can find a call trace, how packets_out can be incremented
      twice for one skb, if snd_nxt and sk_send_head are not synchronized.
      In this case packets_out will be always positive, even when
      sk_write_queue is empty.
      
      tcp_write_wakeup
      	skb = tcp_send_head(sk);
      	tcp_fragment
      		if (!before(tp->snd_nxt, TCP_SKB_CB(buff)->end_seq))
      			tcp_adjust_pcount(sk, skb, diff);
      	tcp_event_new_data_sent
      		tp->packets_out += tcp_skb_pcount(skb);
      
      I think update of snd_nxt isn't required, when a socket is switched from
      repair mode.  Because it's initialized in tcp_connect_init. Then when a
      write queue is restored, snd_nxt is incremented in tcp_event_new_data_sent,
      so it's always is in consistent state.
      
      I have checked, that the bug is not reproduced with this patch and
      all tests about restoring tcp connections work fine.

      lockdep: Correctly annotate hardirq context in irq_exit() · f1a83e65
      Peter Zijlstra authored
      There was a reported deadlock on -rt which lockdep didn't report.
      
      It turns out that in irq_exit() we tell lockdep that the hardirq
      context ends and then do all kinds of locking afterwards.
      
      To fix it, move trace_hardirq_exit() to the very end of irq_exit(), this
      ensures all locking in tick_irq_exit() and rcu_irq_exit() are properly
      recorded as happening from hardirq context.
      
      This however leads to the 'fun' little problem of running softirqs
      while in hardirq context. To cure this make the softirq code a little
      more complex (in the CONFIG_TRACE_IRQFLAGS case).
      
      Due to stack swizzling arch dependent trickery we cannot pass an
      argument to __do_softirq() to tell it if it was done from hardirq
      context or not; so use a side-band argument.
      
      When we do __do_softirq() from hardirq context, 'atomically' flip to
      softirq context and back, so that no locking goes without being in
      either hard- or soft-irq context.
      
      I didn't find any new problems in mainline using this patch, but it
      did show the -rt problem.

        While most of them are just build fixes, there are some fixes for real

        A few of those might be considered a security risk, if the i2c-dev
        module is loaded, as someone could be sending very long I2C data that
        could potentially overflow the Kernel stack.  Ok, as using /dev/i2c-*

         1) there are several patch series ready, but depending on DT review.
            I decided to grant some extra time for DT maintainers to look on
            it, as they're expecting to have more time with the changes agreed
            during ARM mini-summit and KS.  If they can't review in time for
            3.14, I'll review myself and apply for the next merge window.
      
         2) I suspect that having both LinuxCon EU and LinuxCon NA happening
            during the same merge window affected the development
            productivity, as several core media developers participated on
