      Says Jens:
      
       "Time to push off some of the pending items.  I really wanted to wait
        until we had the regression nailed, but alas it's not quite there yet.
        But I'm very confident that it's "just" a missing expire on exit, so
        fix from Tejun should be fairly trivial.  I'm headed out for a week on
        the slopes.
      
        - Killing the barrier part of mtip32xx.  It doesn't really support
          barriers, and it doesn't need them (writes are fully ordered).
      
        - A few fixes from Dan Carpenter, preventing overflows of integer
          multiplication.
      
        - A fixup for loop, fixing a previous commit that didn't quite solve
          the partial read problem from Dave Young.
      
        - A bio integer overflow fix from Kent Overstreet.
      
        - Improvement/fix of the door "keep locked" part of the cdrom shared
          code from Paolo Benzini.
      
        - A few cfq fixes from Shaohua Li.
      
        - A fix for bsg sysfs warning when removing a file it did not create
          from Stanislaw Gruszka.
      
        - Two fixes for floppy from Vivek, preventing a crash.
      
        - A few block core fixes from Tejun.  One killing the over-optimized
          ioc exit path, cleaning that up nicely.  Two others fixing an oops
          on elevator switch, due to calling into the scheduler merge check
          code without holding the queue lock."

      block: fix lockdep warning on io_context release put_io_context() · d8c66c5d
      Tejun Heo 提交于
      11a3122f "block: strip out locking optimization in put_io_context()"
      removed ioc_lock depth lockdep annoation along with locking
      optimization; however, while recursing from put_io_context() is no
      longer possible, ioc_release_fn() may still end up putting the last
      reference of another ioc through elevator, which wlil grab ioc->lock
      triggering spurious (as the ioc is always different one) A-A deadlock
      warning.
      
      As this can only happen one time from ioc_release_fn(), using non-zero
      subclass from ioc_release_fn() is enough.  Use subclass 1.

      Quoth David:
      
      1) GRO MAC header comparisons were ethernet specific, breaking other
         link types.  This required a multi-faceted fix to cure the originally
         noted case (Infiniband), because IPoIB was lying about it's actual
         hard header length.  Thanks to Eric Dumazet, Roland Dreier, and
         others.
      
      2) Fix build failure when INET_UDP_DIAG is built in and ipv6 is modular.
         From Anisse Astier.
      
      3) Off by ones and other bug fixes in netprio_cgroup from Neil Horman.
      
      4) ipv4 TCP reset generation needs to respect any network interface
         binding from the socket, otherwise route lookups might give a
         different result than all the other segments received.  From Shawn
         Lu.
      
      5) Fix unintended regression in ipv4 proxy ARP responses, from Thomas
         Graf.
      
      6) Fix SKB under-allocation bug in sh_eth, from Yoshihiro Shimoda.
      
      7) Revert skge PCI mapping changes that are causing crashes for some
         folks, from Stephen Hemminger.
      
      8) IPV4 route lookups fill in the wildcarded fields of the given flow
         lookup key passed in, which is fine most of the time as this is
         exactly what the caller's want.  However there are a few cases that
         want to retain the original flow key values afterwards, so handle
         those cases properly.  Fix from Julian Anastasov.
      
      9) IGB/IXGBE VF lookup bug fixes from Greg Rose.
      
      10) Properly null terminate filename passed to ethtool flash device
          method, from Ben Hutchings.
      
      11) S3 resume fix in via-velocity from David Lv.
      
      12) Fix double SKB free during xmit failure in CAIF, from Dmitry
          Tarnyagin.

      net: Don't proxy arp respond if iif == rt->dst.dev if private VLAN is disabled · 70620c46
      Thomas Graf 提交于
      Commit 653241 (net: RFC3069, private VLAN proxy arp support) changed
      the behavior of arp proxy to send arp replies back out on the interface
      the request came in even if the private VLAN feature is disabled.
      
      Previously we checked rt->dst.dev != skb->dev for in scenarios, when
      proxy arp is enabled on for the netdevice and also when individual proxy
      neighbour entries have been added.
      
      This patch adds the check back for the pneigh_lookup() scenario.

      the nexthop of SRR in ip_option->nexthop and update iph->daddr until
      we get to ip_forward_options(), but we need to update it before
      ip_rt_get_source(), otherwise we may get a wrong src.

      When the netprio_cgroup module is not loaded, net_prio_subsys_id
      is -1, and so sock_update_prioidx() accesses cgroup_subsys array
      with negative index subsys[-1].

      Neil Horman 提交于
      So we delay the allocation till the priority is set through cgroup,
      and this makes skb_update_priority() faster when it's not set.
      
      This also eliminates an off-by-one bug similar with the one fixed
      in the previous patch.
