      Pull networking fixes from David Miller:
      
       1) Receive packet length needs to be adjust by 2 on RX to accomodate
          the two padding bytes in altera_tse driver.  From Vlastimil Setka.
      
       2) If rx frame is dropped due to out of memory in macb driver, we leave
          the receive ring descriptors in an undefined state.  From Punnaiah
          Choudary Kalluri
      
       3) Some netlink subsystems erroneously signal NLM_F_MULTI.  That is
          only for dumps.  Fix from Nicolas Dichtel.
      
       4) Fix mis-use of raw rt->rt_pmtu value in ipv4, one must always go via
          the ipv4_mtu() helper.  From Herbert Xu.
      
       5) Fix null deref in bridge netfilter, and miscalculated lengths in
          jump/goto nf_tables verdicts.  From Florian Westphal.
      
       6) Unhash ping sockets properly.
      
       7) Software implementation of BPF divide did 64/32 rather than 64/64
          bit divide.  The JITs got it right.  Fix from Alexei Starovoitov.

      virtio: pass baton to Michael Tsirkin · feda5f93
      Rusty Russell authored
      With my job change kernel work will be "own time"; I'm keeping lguest
      and modules (and the virtio standards work), but virtio kernel has to
      go.
      
      This makes it clear that Michael is in charge.  He's good, but having
      me watch over his shoulder won't help.
      
      Good luck Michael!

      If we don't do that, then the poison value is left in the ->pprev
      backlink.
      
      This can cause crashes if we do a disconnect, followed by a connect().

      Merge branch 'rt6_pmtu' · 36c82963
      David S. Miller authored
      Martin KaFai Lau says:
      
      ====================
      ipv6: Stop /128 route from disappearing after pmtu update
      
      The series is separated from another patch series,
      'ipv6: Only create RTF_CACHE route after encountering pmtu exception',
      which can be found here:
      http://thread.gmane.org/gmane.linux.network/359140
      
      This series focus on fixing the /128 route issues.  It is currently targeted
      for net-next due to the number of code churn but it is also applicable
      to net (should be without conflict).  The original reported problem can be
      found here:
      http://thread.gmane.org/gmane.linux.network/348138
      
      Patch 01 and 02 are to prepare the fib6 search to expect both the
      RTF_CACHE clone and its original route exist at the same fib6_node.
      
      Patch 03 fixes the /128 route disappearing bug.
      
      Patch 04 and 05 stop rt6_info from using the inet_peer's metrics to
      avoid the /128 routes (like the /128 clone and its original route)
      from stepping on each others' metrics.
      
      The second patch is by 'Steffen Klassert <steffen.klassert@secunet.com>'
      which I pulled off from netdev.  The third patch is also mostly by
      Steffen with one minor optimization.
      
      Many thanks to Hannes Frederic Sowa <hannes@stressinduktion.org> on
      reviewing the patches and giving advice.

      ipv6: Remove DST_METRICS_FORCE_OVERWRITE and _rt6i_peer · afc4eef8
      Martin KaFai Lau authored
      _rt6i_peer is no longer needed after the last patch,
      'ipv6: Stop rt6_info from using inet_peer's metrics'.
      
      DST_METRICS_FORCE_OVERWRITE is added by
      commit e5fd387a ("ipv6: do not overwrite inetpeer metrics prematurely").
      Since inetpeer is no longer used for metrics, this bit is also not needed.

      ipv6: Stop rt6_info from using inet_peer's metrics · 4b32b5ad
      Martin KaFai Lau authored
      inet_peer is indexed by the dst address alone.  However, the fib6 tree
      could have multiple routing entries (rt6_info) for the same dst. For
      example,
      1. A /128 dst via multiple gateways.
      2. A RTF_CACHE route cloned from a /128 route.
      
      In the above cases, all of them will share the same metrics and
      step on each other.
      
      This patch will steer away from inet_peer's metrics and use
      dst_cow_metrics_generic() for everything.
      
      Change Highlights:
      1. Remove rt6_cow_metrics() which currently acquires metrics from
         inet_peer for DST_HOST route (i.e. /128 route).
      2. Add rt6i_pmtu to take care of the pmtu update to avoid creating a
         full size metrics just to override the RTAX_MTU.
      3. After (2), the RTF_CACHE route can also share the metrics with its
         dst.from route, by:
         dst_init_metrics(&cache_rt->dst, dst_metrics_ptr(cache_rt->dst.from), true);
      4. Stop creating RTF_CACHE route by cloning another RTF_CACHE route.  Instead,
         directly clone from rt->dst.
      
         [ Currently, cloning from another RTF_CACHE is only possible during
           rt6_do_redirect().  Also, the old clone is removed from the tree
           immediately after the new clone is added. ]
      
         In case of cloning from an older redirect RTF_CACHE, it should work as
         before.
      
         In case of cloning from an older pmtu RTF_CACHE, this patch will forget
         the pmtu and re-learn it (if there is any) from the redirected route.
      
      The _rt6i_peer and DST_METRICS_FORCE_OVERWRITE will be removed
      in the next cleanup patch.
