      Pull networking fixes from David Miller:
      
       1) In TCP, don't register an FRTO for cumulatively ACK'd data that was
          previously SACK'd, from Neal Cardwell.
      
       2) Need to hold RNL mutex in ipv4 multicast code namespace cleanup,
          from Cong WANG.
      
       3) Similarly we have to hold RNL mutex for fib_rules_unregister(), also
          from Cong WANG.
      
       4) Revert and rework netns nsid allocation fix, from Nicolas Dichtel.
      
       5) When we encapsulate for a tunnel device, skb->sk still points to the
          user socket.  So this leads to cases where we retraverse the
          ipv4/ipv6 output path with skb->sk being of some other address
          family (f.e. AF_PACKET).  This can cause things to crash since the
          ipv4 output path is dereferencing an AF_PACKET socket as if it were
          an ipv4 one.
      
          The short term fix for 'net' and -stable is to elide these socket
          checks once we've entered an encapsulation sequence by testing
          xmit_recursion.
      
          Longer term we have a better solution wherein we pass the tunnel's
          socket down through the output paths, but that is way too invasive
          for 'net' and -stable.
      
          From Hannes Frederic Sowa.
      
       6) l2tp_init() failure path forgets to unregister per-net ops, from
          Cong WANG.

      Commit 1daa4303 ("net/mlx4_core: Deprecate error message at
      ConnectX-2 cards startup to debug") did the deprecation only for port 1
      of the card. Need to deprecate for port 2 as well.

      net: dsa: fix filling routing table from OF description · 30303813
      Pavel Nakonechny authored
      According to description in 'include/net/dsa.h', in cascade switches
      configurations where there are more than one interconnected devices,
      'rtable' array in 'dsa_chip_data' structure is used to indicate which
      port on this switch should be used to send packets to that are destined
      for corresponding switch.
      
      However, dsa_of_setup_routing_table() fills 'rtable' with port numbers
      of the _target_ switch, but not current one.
      
      This commit removes redundant devicetree parsing and adds needed port
      number as a function argument. So dsa_of_setup_routing_table() now just
      looks for target switch number by parsing parent of 'link' device node.
      
      To remove possible misunderstandings with the way of determining target
      switch number, a corresponding comment was added to the source code and
      to the DSA device tree bindings documentation file.
      
      This was tested on a custom board with two Marvell 88E6095 switches with
      following corresponding routing tables: { -1, 10 } and { 8, -1 }.

      not be called directly. The result of calling it directly is as below:

      ipv6: protect skb->sk accesses from recursive dereference inside the stack · f60e5990
      hannes@stressinduktion.org authored
      We should not consult skb->sk for output decisions in xmit recursion
      levels > 0 in the stack. Otherwise local socket settings could influence
      the result of e.g. tunnel encapsulation process.
      
      ipv6 does not conform with this in three places:
      
      1) ip6_fragment: we do consult ipv6_npinfo for frag_size
      
      2) sk_mc_loop in ipv6 uses skb->sk and checks if we should
         loop the packet back to the local socket
      
      3) ip6_skb_dst_mtu could query the settings from the user socket and
         force a wrong MTU
      
      Furthermore:
      In sk_mc_loop we could potentially land in WARN_ON(1) if we use a
      PF_PACKET socket ontop of an IPv6-backed vxlan device.
      
      Reuse xmit_recursion as we are currently only interested in protecting
      tunnel devices.
