      Pull networking fixes from David Miller:
       1) Null termination fix in dns_resolver got the pointer dereferncing
          wrong, fix from Ben Hutchings.
       2) ip_options_compile() has a benign but real buffer overflow when
          parsing options.  From Eric Dumazet.
       3) Table updates can crash in netfilter's nftables if none of the state
          flags indicate an actual change, from Pablo Neira Ayuso.
       4) Fix race in nf_tables dumping, also from Pablo.
       5) GRE-GRO support broke the forwarding path because the segmentation
          state was not fully initialized in these paths, from Jerry Chu.
       6) sunvnet driver leaks objects and potentially crashes on module
          unload, from Sowmini Varadhan.
       7) We can accidently generate the same handle for several u32
          classifier filters, fix from Cong Wang.
       8) Several edge case bug fixes in fragment handling in xen-netback,
          from Zoltan Kiss.

       "Tony Luck found that using the "uptime" trace clock that uses jiffies

        with the tracing system and making the clock useless.
        He converted that clock to use jiffies_64 and made it into a counter
        instead of nanosecond conversions, and displayed the clock with the
        straight jiffy count, which works much better than it did in the past"

      pull request [net]: batman-adv 20140721
      here you have two fixes that we have been testing for quite some time
      (this is why they arrived a bit late in the rc cycle).
      Patch 1) ensures that BLA packets get dropped and not forwarded to the
      mesh even if they reach batman-adv within QinQ frames. Forwarding them
      into the mesh means messing up with the TT database of other nodes which
      can generate all kind of unexpected behaviours during route computation.
      Patch 2) avoids a couple of race conditions triggered upon fast VLAN
      deletion-addition. Such race conditions are pretty dangerous because
      they not only create inconsistencies in the TT database of the nodes
      in the network, but such scenario is also unrecoverable (unless
      nodes are rebooted).

      ipv4: fix buffer overflow in ip_options_compile() · 10ec9472
      Eric Dumazet authored
      There is a benign buffer overflow in ip_options_compile spotted by
      AddressSanitizer[1] :
      Its benign because we always can access one extra byte in skb->head
      (because header is followed by struct skb_shared_info), and in this case
      this byte is not even used.

      tracing: Fix wraparound problems in "uptime" trace clock · 58d4e21e

      The "uptime" trace clock added in:
          commit 8aacf017
          tracing: Add "uptime" trace clock that uses jiffies
      has wraparound problems when the system has been up more
      than 1 hour 11 minutes and 34 seconds. It converts jiffies
      to nanoseconds using:
              (u64)jiffies_to_usecs(jiffy) * 1000ULL
      but since jiffies_to_usecs() only returns a 32-bit value, it
      truncates at 2^32 microseconds.  An additional problem on 32-bit
      systems is that the argument is "unsigned long", so fixing the
      return value only helps until 2^32 jiffies (49.7 days on a HZ=1000
      Avoid these problems by using jiffies_64 as our basis, and
      not converting to nanoseconds (we do convert to clock_t because
      user facing API must not be dependent on internal kernel
      HZ values).

      batman-adv: fix TT VLAN inconsistency on VLAN re-add · 35df3b29
      Antonio Quartulli authored
      When a VLAN interface (on top of batX) is removed and
      re-added within a short timeframe TT does not have enough
      time to properly cleanup. This creates an internal TT state
      mismatch as the newly created softif_vlan will be
      initialized from scratch with a TT client count of zero
      (even if TT entries for this VLAN still exist). The
      resulting TT messages are bogus due to the counter / tt
      client listing mismatch, thus creating inconsistencies on
      every node in the network
      To fix this issue destroy_vlan() has to not free the VLAN
      object immediately but it has to be kept alive until all the
      TT entries for this VLAN have been removed. destroy_vlan()
      still removes the sysfs folder so that the user has the
      feeling that everything went fine.
      If the same VLAN is re-added before the old object is free'd,
      then the latter is resurrected and re-used.
      Implement such behaviour by increasing the reference counter
      of a softif_vlan object every time a new local TT entry for
      such VLAN is created and remove the object from the list
      only when all the TT entries have been destroyed.
