      Pull networking fixes from David Miller:
      
       1) Verify lengths of keys provided by the user is AF_KEY, from Kevin
          Easton.
      
       2) Add device ID for BCM89610 PHY. Thanks to Bhadram Varka.
      
       3) Add Spectre guards to some ATM code, courtesy of Gustavo A. R.
          Silva.
      
       4) Fix infinite loop in NSH protocol code. To Eric Dumazet we are most
          grateful for this fix.
      
       5) Line up /proc/net/netlink headers properly. This fix from YU Bo, we
          do appreciate.
      
       6) Use after free in TLS code. Once again we are blessed by the
          honorable Eric Dumazet with this fix.
      
       7) Fix regression in TLS code causing stalls on partial TLS records.
          This fix is bestowed upon us by Andrew Tomt.
      
       8) Deal with too small MTUs properly in LLC code, another great gift
          from Eric Dumazet.
      
       9) Handle cached route flushing properly wrt. MTU locking in ipv4, to
          Hangbin Liu we give thanks for this.
      
      10) Fix regression in SO_BINDTODEVIC handling wrt. UDP socket demux.
          Paolo Abeni, he gave us this.
      
      11) Range check coalescing parameters in mlx4 driver, thank you Moshe
          Shemesh.
      
      12) Some ipv6 ICMP error handling fixes in rxrpc, from our good brother
          David Howells.
      
      13) Fix kexec on mlx5 by freeing IRQs in shutdown path. Daniel Juergens,
          you're the best!
      
      14) Don't send bonding RLB updates to invalid MAC addresses. Debabrata
          Benerjee saved us!
      
      15) Uh oh, we were leaking in udp_sendmsg and ping_v4_sendmsg. The ship
          is now water tight, thanks to Andrey Ignatov.
      
      16) IPSEC memory leak in ixgbe from Colin Ian King, man we've got holes
          everywhere!
      
      17) Fix error path in tcf_proto_create, Jiri Pirko what would we do
          without you!

      net sched actions: fix refcnt leak in skbmod · a52956df
      Roman Mashak authored
      When application fails to pass flags in netlink TLV when replacing
      existing skbmod action, the kernel will leak refcnt:
      
      $ tc actions get action skbmod index 1
      total acts 0
      
              action order 0: skbmod pipe set smac 00:11:22:33:44:55
               index 1 ref 1 bind 0
      
      For example, at this point a buggy application replaces the action with
      index 1 with new smac 00:aa:22:33:44:55, it fails because of zero flags,
      however refcnt gets bumped:
      
      $ tc actions get actions skbmod index 1
      total acts 0
      
              action order 0: skbmod pipe set smac 00:11:22:33:44:55
               index 1 ref 2 bind 0
      $
      
      Tha patch fixes this by calling tcf_idr_release() on existing actions.

      Intel Wired LAN Driver Updates 2018-05-11
      
      This series contains fixes to the ice, ixgbe and ixgbevf drivers.
      
      Jeff Shaw provides a fix to ensure rq_last_status gets set, whether or
      not the hardware responds with an error in the ice driver.
      
      Emil adds a check for unsupported module during the reset routine for
      ixgbe.
      
      Luc Van Oostenryck fixes ixgbevf_xmit_frame() where it was not using the
      correct return value (int).

      Here are three fixes for AF_RXRPC and two tracepoints that were useful for

       (1) Fix missing start of expect-Rx-by timeout on initial packet
           transmission so that calls will time out if the peer doesn't respond.
      
       (2) Fix error reception on AF_INET6 sockets by using the correct family of
           sockopts on the UDP transport socket.
      
       (3) Fix setting the minimum security level on kernel calls so that they
           can be encrypted.
      
       (4) Add a tracepoint to log ICMP/ICMP6 and other error reports from the
           transport socket.
      
       (5) Add a tracepoint to log UDP sendmsg failure so that we can find out if
           transmission failure occurred on the UDP socket.

      The caller calls action's ->init() and passes pointer to "struct tc_action *a",
      which later may be initialized to point at the existing action, otherwise
      "struct tc_action *a" is still invalid, and therefore dereferencing it is an
      error as happens in tcf_idr_release, where refcnt is decremented.
      
      So in case of missing flags tcf_idr_release must be called only for
      existing actions.

      Prior to this commit, the rq_last_status was only set when hardware

      sh: switch to NO_BOOTMEM · ac21fc2d
      Rob Herring authored
      Commit 0fa1c579 ("of/fdt: use memblock_virt_alloc for early alloc")
      inadvertently switched the DT unflattening allocations from memblock to
      bootmem which doesn't work because the unflattening happens before
      bootmem is initialized. Swapping the order of bootmem init and
      unflattening could also fix this, but removing bootmem is desired. So
      enable NO_BOOTMEM on SH like other architectures have done.

      mmap: introduce sane default mmap limits · be83bbf8
      Linus Torvalds authored
      The internal VM "mmap()" interfaces are based on the mmap target doing
      everything using page indexes rather than byte offsets, because
      traditionally (ie 32-bit) we had the situation that the byte offset
      didn't fit in a register.  So while the mmap virtual address was limited
      by the word size of the architecture, the backing store was not.
      
      So we're basically passing "pgoff" around as a page index, in order to
      be able to describe backing store locations that are much bigger than
      the word size (think files larger than 4GB etc).
      
      But while this all makes a ton of sense conceptually, we've been dogged
      by various drivers that don't really understand this, and internally
      work with byte offsets, and then try to work with the page index by
      turning it into a byte offset with "pgoff << PAGE_SHIFT".
      
      Which obviously can overflow.
      
      Adding the size of the mapping to it to get the byte offset of the end
      of the backing store just exacerbates the problem, and if you then use
      this overflow-prone value to check various limits of your device driver
      mmap capability, you're just setting yourself up for problems.
      
      The correct thing for drivers to do is to do their limit math in page
      indices, the way the interface is designed.  Because the generic mmap
      code _does_ test that the index doesn't overflow, since that's what the
      mmap code really cares about.
      
      HOWEVER.
      
      Finding and fixing various random drivers is a sisyphean task, so let's
      just see if we can just make the core mmap() code do the limiting for
      us.  Realistically, the only "big" backing stores we need to care about
      are regular files and block devices, both of which are known to do this
      properly, and which have nice well-defined limits for how much data they
      can access.
      
      So let's special-case just those two known cases, and then limit other
      random mmap users to a backing store that still fits in "unsigned long".
      Realistically, that's not much of a limit at all on 64-bit, and on
      32-bit architectures the only worry might be the GPU drivers, which can
      have big physical address spaces.
      
      To make it possible for drivers like that to say that they are 64-bit
      clean, this patch does repurpose the "FMODE_UNSIGNED_OFFSET" bit in the
      file flags to allow drivers to mark their file descriptors as safe in
      the full 64-bit mmap address space.
      
      [ The timing for doing this is less than optimal, and this should really
        go in a merge window. But realistically, this needs wide testing more
        than it needs anything else, and being main-line is the only way to do
        that.
      
        So the earlier the better, even if it's outside the proper development
        cycle        - Linus ]

      Whenever return happens in udp_sendmsg() or ping_v4_sendmsg() IP options
      have to be freed if they were allocated previously.
