      Pull networking updates from David Miller:
      
       1) Missing netlink attribute validation in nft_lookup, from Patrick
          McHardy.
      
       2) Restrict ipv6 partial checksum handling to UDP, since that's the
          only case it works for.  From Vlad Yasevich.
      
       3) Clear out silly device table sentinal macros used by SSB and BCMA
          drivers.  From Joe Perches.
      
       4) Make sure the remote checksum code never creates a situation where
          the remote checksum is applied yet the tunneling metadata describing
          the remote checksum transformation is still present.  Otherwise an
          external entity might see this and apply the checksum again.  From
          Tom Herbert.
      
       5) Use msecs_to_jiffies() where applicable, from Nicholas Mc Guire.
      
       6) Don't explicitly initialize timer struct fields, use setup_timer()
          and mod_timer() instead.  From Vaishali Thakkar.
      
       7) Don't invoke tg3_halt() without the tp->lock held, from Jun'ichi
          Nomura.
      
       8) Missing __percpu annotation in ipvlan driver, from Eric Dumazet.
      
       9) Don't potentially perform skb_get() on shared skbs, also from Eric
          Dumazet.
      
      10) Fix COW'ing of metrics for non-DST_HOST routes in ipv6, from Martin
          KaFai Lau.
      
      11) Fix merge resolution error between the iov_iter changes in vhost and
          some bug fixes that occurred at the same time.  From Jason Wang.
      
      12) If rtnl_configure_link() fails we have to perform a call to
          ->dellink() before unregistering the device.  From WANG Cong.

      md/raid5: Fix livelock when array is both resyncing and degraded. · 26ac1073
      NeilBrown authored
      Commit a7854487
      
      :
        md: When RAID5 is dirty, force reconstruct-write instead of read-modify-write.
      
      Causes an RCW cycle to be forced even when the array is degraded.
      A degraded array cannot support RCW as that requires reading all data
      blocks, and one may be missing.
      
      Forcing an RCW when it is not possible causes a live-lock and the code
      spins, repeatedly deciding to do something that cannot succeed.
      
      So change the condition to only force RCW on non-degraded arrays.

      The value resulting from the SECCOMP_RET_DATA mask could exceed MAX_ERRNO
      when setting errno during a SECCOMP_RET_ERRNO filter action.  This makes
      sure we have a reliable value being set, so that an invalid errno will not
      be ignored by userspace.

      scripts/gdb: disable pagination while printing from breakpoint handler · a9c5bcfa
      Jan Kiszka authored
      
      
      While reporting the (refreshed) list of modules on automatic updates we
      may hit the page boundary of the output console and cause a stop if
      pagination is enabled.  However, gdb does not accept user input while
      running over the breakpoint handler.  So we get stuck, and the user is
      forced to interrupt gdb.
      
      Resolve this by disabling pagination during automatic symbol updates.  We
      restore the user's configuration once done.

      Daniel Wagner authored
      
      
      The iterator does not return any task_struct from the thread_group list
      because the first condition in the 'if not t or ...' will only be the
      first time None.
      
      Instead of keeping track of the state ourself in the next() function, we
      fall back using Python's generator.

      scripts/gdb: port to python3 / gdb7.7 · 276d97d9

      I tried to use these scripts in an ubuntu 14.04 host (gdb 7.7 compiled
      against python 3.3) but there were several errors.
      
      I believe this patch fixes these issues so that the commands now work (I
      tested lx-symbols, lx-dmesg, lx-lsmod).
      
      Main issues that needed to be resolved:
      
        * In python 2 iterators have a "next()" method. In python 3 it is
          __next__() instead (so let's just add both).
      
        * In older python versions there was an implicit conversion
          in object.__format__() (used when an object is in string.format())
          where it was converting the object to str first and then
          calling str's __format__(). This has now been removed so
          we must explicitly convert to str the objects for which
          we need to keep this behavior.
      
        * In dmesg.py: in python 3 log_buf is now a "memoryview" object
          which needs to be converted to a string in order to use string
          methods like "splitlines()". Luckily memoryview exists in
          python 2.7.6 as well, so we can convert log_buf to memoryview
          and use the same code in both python 2 and python 3.
      
      This version of the patch has now been tested with gdb 7.7 and both python
      3.4 and python 2.7.6 (I think asking for at least python 2.7.6 is a
      reasonable requirement instead of complicating the code with version
      checks etc).
