      net: add real socket cookies · 33cf7c90
      Eric Dumazet authored
      A long standing problem in netlink socket dumps is the use
      of kernel socket addresses as cookies.
      
      1) It is a security concern.
      
      2) Sockets can be reused quite quickly, so there is
         no guarantee a cookie is used once and identify
         a flow.
      
      3) request sock, establish sock, and timewait socks
         for a given flow have different cookies.
      
      Part of our effort to bring better TCP statistics requires
      to switch to a different allocator.
      
      In this patch, I chose to use a per network namespace 64bit generator,
      and to use it only in the case a socket needs to be dumped to netlink.
      (This might be refined later if needed)
      
      Note that I tried to carry cookies from request sock, to establish sock,
      then timewait sockets.

      fib_trie: Only display main table in /proc/net/route · 654eff45
      Alexander Duyck authored
      When we merged the tries for local and main I had overlooked the iterator
      for /proc/net/route.  As a result it was outputting both local and main
      when the two tries were merged.
      
      This patch resolves that by only providing output for aliases that are
      actually in the main trie.  As a result we should go back to the original
      behavior which I assume will be necessary to maintain legacy support.

      tipc: ensure that idle links are deleted when a bearer is disabled · 169bf912
      Jon Paul Maloy authored
      commit afaa3f65
      (tipc: purge links when bearer is disabled) was an attempt to resolve
      a problem that turned out to have a more profound reason.
      
      When we disable a bearer, we delete all its pertaining links if
      there is no other bearer to perform failover to, or if the module
      is shutting down. In case there are dual bearers, we wait with
      deleting links until the failover procedure is finished.
      
      However, this misses the case when a link on the removed bearer
      was already down, so that there will be no failover procedure to
      finish the link delete. This causes confusion if a new bearer is
      added to replace the removed one, and also entails a small memory
      leak.
      
      This commit takes the current state of the link into account when
      deciding when to delete it, and also reverses the above-mentioned
      commit.

      fib_trie: Address possible NULL pointer dereference in resize · ddb4b9a1
      Alexander Duyck authored
      If the inflate call failed it would return NULL.  As a result tp would be
      set to NULL and cause use to trigger a NULL pointer dereference in
      should_halve if the inflate failed on the first attempt.
      
      In order to prevent this we should decrement max_work before we actually
      attempt to inflate as this will force us to exit before attempting to halve
      a node we should have inflated.  In order to keep things symmetric between
      inflate and halve I went ahead and also moved the decrement of max_work for
      the halve case as well so we take care of that before we actually attempt
      to halve the tnode.

      fib_trie: Correctly handle case of key == 0 in leaf_walk_rcu · 3ec320dd
      Alexander Duyck authored
      In the case of a trie that had no tnodes with a key of 0 the initial
      look-up would fail resulting in an out-of-bounds cindex on the first tnode.
      This resulted in an entire trie being skipped.
      
      In order resolve this I have updated the cindex logic in the initial
      look-up so that if the key is zero we will always traverse the child zero
      path.

      netfilter: bridge: use rcu hook to resolve br_netfilter dependency · 1a4ba64d
      Pablo Neira Ayuso authored
      e5de75bf ("netfilter: bridge: move DNAT helper to br_netfilter") results
      in the following link problem:
      
      net/bridge/br_device.c:29: undefined reference to `br_nf_prerouting_finish_bridge`
      
      Moreover it creates a hard dependency between br_netfilter and the
      bridge core, which is what we've been trying to avoid so far.
      
      Resolve this problem by using a hook structure so we reduce #ifdef
      pollution and keep bridge netfilter specific code under br_netfilter.c
      which was the original intention.

      net: dsa: remove restriction on platform_device
      
      This patch series removes the restriction in DSA to operate exclusively with
      platform_device Ethernet MAC drivers when using Device Tree. This basically
      allows arbitrary Ethernet MAC drivers to be used now in conjunction with
      Device Tree.
      
      The reason was that DSA was using a of_find_device_by_node() which limits
      the device_node to device pointer search exclusively to platform_device,
      in our case, we are interested in doing a "class" research and lookup the
      net_device.
      
      Thanks to Chris Packham for testing this on his platform.

      net: dsa: utilize of_find_net_device_by_node · 769a0202
      Florian Fainelli authored
      Using of_find_device_by_node() restricts the search to platform_device that
      match the specified device_node pointer. This is not even remotely true for
      network devices backed by a pci_device for instance.
      
      of_find_net_device_by_node() allows us to do a more thorough lookup to find the
      struct net_device corresponding to a particular device_node pointer.
      
      For symetry with the non-OF code path, we hold the net_device pointer in
      dsa_probe() just like what dev_to_net_dev() does when we call this
      function.

      net: core: add of_find_net_device_by_node() · aa836df9
      Florian Fainelli authored
      Add a helper function which allows getting the struct net_device pointer
      associated with a given struct device_node pointer. This is useful for
      instance for DSA Ethernet devices not backed by a platform_device, but a PCI
      device.
      
      Since we need to access net_class which is not accessible outside of
      net/core/net-sysfs.c, this helper function is also added here and gated
      with CONFIG_OF_NET.
      
      Network devices initialized with SET_NETDEV_DEV() are also taken into
      account by checking for dev->parent first and then falling back to
      checking the device pointer within struct net_device.

        As well as with function tracing too.  Pratyush Anand first reported
        this issue to me and supplied a patch.  When I tested this on my x86
        test box, it caused thousands of backtraces and warnings to appear in
        dmesg, which also caused a denial of service (a warning for every
        function that was listed).  I applied Pratyush's patch but it did not
        fix the issue for me.  I looked into it and found a slight problem
        with trampoline accounting.  I fixed it and sent Pratyush a patch, but
        he said that it did not fix the issue for him.
      
        I later learned tha Pratyush was using an ARM64 server, and when I
        tested on my ARM board, I was able to reproduce the same issue as
        Pratyush.  After applying his patch, it fixed the problem.  The above
        test uncovered two different bugs, one in x86 and one in ARM and
        ARM64.  As this looked like it would affect PowerPC, I tested it on my
        PPC64 box.  It too broke, but neither the patch that fixed ARM or x86
        fixed this box (the changes were all in generic code!).  The above
        test, uncovered two more bugs that affected PowerPC.  Again, the
        changes were only done to generic code.  It's the way the arch code
        expected things to be done that was different between the archs.  Some
        where more sensitive than others.
      
        The rest of this series fixes the PPC bugs as well"

       5) Fix OOPSes triggerable by the ping protocol module, due to missing
          address family validations etc.  From Lorenzo Colitti.
      
       6) Don't use RCU locking in sleepable context in team driver, from Jiri
          Pirko.
      
       7) xen-netback miscalculates statistic offset pointers when reporting
          the stats to userspace.  From David Vrabel.
      
       8) Fix a leak of up to 256 pages per VIF destroy in xen-netaback, also
          from David Vrabel.
      
       9) ip_check_defrag() cannot assume that skb_network_offset(),
          particularly when it is used by the AF_PACKET fanout defrag code.
          From Alexander Drozdov.
      
      10) gianfar driver doesn't query OF node names properly when trying to
          determine the number of hw queues available.  Fix it to explicitly
          check for OF nodes named queue-group.  From Tobias Waldekranz.
      
      11) MID field in macb driver should be 12 bits, not 16.  From Punnaiah
          Choudary Kalluri.
      
      12) Fix unintentional regression in traceroute due to timestamp socket
          option changes.  Empty ICMP payloads should be allowed in
          non-timestamp cases.  From Willem de Bruijn.
      
      13) When devices are unregistered, we have to get rid of AF_PACKET
          multicast list entries that point to it via ifindex.  Fix from
          Francesco Ruggeri.
