      ipv6: release reference of ip6_null_entry's dst entry in __ip6_del_rt · 6825a26c
      Gao feng authored
      as we hold dst_entry before we call __ip6_del_rt,
      so we should alse call dst_release not only return
      -ENOENT when the rt6_info is ip6_null_entry.
      
      and we already hold the dst entry, so I think it's
      safe to call dst_release out of the write-read lock.

      ====================
      here are three patches for the v3.7 release cycle. Two patches by Peter Senna
      Tschudin which fix the return values in the error handling path of the sja1000
      peak pci and pcmcia driver. And one patch by myself that fixes a compile
      breakage of the mpc5xxx_can mscan driver due to a section conflict.

      tipc: prevent dropped connections due to rcvbuf overflow · e57edf6b
      Erik Hugne authored
      When large buffers are sent over connected TIPC sockets, it
      is likely that the sk_backlog will be filled up on the
      receiver side, but the TIPC flow control mechanism is happily
      unaware of this since that is based on message count.
      
      The sender will receive a TIPC_ERR_OVERLOAD message when this occurs
      and drop it's side of the connection, leaving it stale on
      the receiver end.
      
      By increasing the sk_rcvbuf to a 'worst case' value, we avoid the
      overload caused by a full backlog queue and the flow control
      will work properly.
      
      This worst case value is the max TIPC message size times
      the flow control window, multiplied by two because a sender
      will transmit up to double the window size before a port is marked
      congested.
      We multiply this by 2 to account for the sk_buff and other overheads.

      silence some noisy printks in irda · 09689581
      Dave Jones authored
      Fuzzing causes these printks to spew constantly.
      Changing them to DEBUG statements is consistent with other usage in the file,
      and makes them disappear when CONFIG_IRDA_DEBUG is disabled.

      team: set qdisc_tx_busylock to avoid LOCKDEP splat · b3c581d5
      Eric Dumazet authored
      If a qdisc is installed on a team device, its possible to get
      a lockdep splat under stress, because nested dev_queue_xmit() can
      lock busylock a second time (on a different device, so its a false
      positive)
      
      Avoid this problem using a distinct lock_class_key for team
      devices.

      sctp: check src addr when processing SACK to update transport state · edfee033
      Nicolas Dichtel authored
      Suppose we have an SCTP connection with two paths. After connection is
      established, path1 is not available, thus this path is marked as inactive. Then
      traffic goes through path2, but for some reasons packets are delayed (after
      rto.max). Because packets are delayed, the retransmit mechanism will switch
      again to path1. At this time, we receive a delayed SACK from path2. When we
      update the state of the path in sctp_check_transmitted(), we do not take into
      account the source address of the SACK, hence we update the wrong path.

      ipv4: add a fib_type to fib_info · f4ef85bb
      Eric Dumazet authored
      commit d2d68ba9 (ipv4: Cache input routes in fib_info nexthops.)
      introduced a regression for forwarding.
      
      This was hard to reproduce but the symptom was that packets were
      delivered to local host instead of being forwarded.
      
      David suggested to add fib_type to fib_info so that we dont
      inadvertently share same fib_info for different purposes.
      
      With help from Julian Anastasov who provided very helpful
      hints, reproduced here :
      
      <quote>
              Can it be a problem related to fib_info reuse
      from different routes. For example, when local IP address
      is created for subnet we have:
      
      broadcast 192.168.0.255 dev DEV  proto kernel  scope link  src
      192.168.0.1
      192.168.0.0/24 dev DEV  proto kernel  scope link  src 192.168.0.1
      local 192.168.0.1 dev DEV  proto kernel  scope host  src 192.168.0.1
      
              The "dev DEV  proto kernel  scope link  src 192.168.0.1" is
      a reused fib_info structure where we put cached routes.
      The result can be same fib_info for 192.168.0.255 and
      192.168.0.0/24. RTN_BROADCAST is cached only for input
      routes. Incoming broadcast to 192.168.0.255 can be cached
      and can cause problems for traffic forwarded to 192.168.0.0/24.
      So, this patch should solve the problem because it
      separates the broadcast from unicast traffic.
      
              And the ip_route_input_slow caching will work for
      local and broadcast input routes (above routes 1 and 3) just
      because they differ in scope and use different fib_info.
      
      </quote>
      
      Many thanks to Chris Clayton for his patience and help.

      Since commit:
          6d99c4c5 can: mpc5xxx_can: make data used as *of_device_id.data const
      
      both "struct mpc5xxx_can_data mpc5200_can_data" and "mpc5121_can_data" are
      marked as "const" but also as "__devinitdata". This leads to the following

      drivers/net/can/mscan/mpc5xxx_can.c:388: error: mpc5121_can_data causes a section type conflict
      
      This patch changes the "__devinitdata" to "__devinitconst" and marks the

         - refactoring from Thierry Redding at Arnd Bergmann's request to use
           the seq_file iterator interface in gpiolib.
         - A new driver for Avionic Design's N-bit GPIO expander.
         - Two instances of mutexes replaced by spinlocks from Axel Lin to
           code that is supposed to be fastpath compliant.
         - IRQ demuxer and gpio_to_irq() support for pcf857x by Kuninori
           Morimoto.
         - Dynamic GPIO numbers, device tree support, daisy chaining and some
           other fixes for the 74x164 driver by Maxime Ripard.
         - IRQ domain and device tree support for the tc3589x driver by Lee
           Jones.
         - Some conversion to use managed resources devm_* code.
         - Some instances of clk_prepare() or clk_prepare_enable() added to
           support the new, stricter common clock framework.
         - Some for_each_set_bit() simplifications.
         - Then a lot of fixes as we fixed up all of the above tripping over
           our own shoelaces and that kind of thing."

      workqueue: avoid using deprecated functions · 916082b0
      Linus Torvalds authored
      The network merge brought in a few users of functions that got
      deprecated by the workqueue cleanups: the 'system_nrt_wq' is now the
      same as the regular system_wq, since all workqueues are now non-
      reentrant.
      
      Similarly, remove one use of flush_work_sync() - the regular
      flush_work() has become synchronous, and the "_sync()" version is thus
      deprecated as being superfluous.

      Pull networking changes from David Miller:
      
       1) GRE now works over ipv6, from Dmitry Kozlov.
      
       2) Make SCTP more network namespace aware, from Eric Biederman.
      
       3) TEAM driver now works with non-ethernet devices, from Jiri Pirko.
      
       4) Make openvswitch network namespace aware, from Pravin B Shelar.
      
       5) IPV6 NAT implementation, from Patrick McHardy.
      
       6) Server side support for TCP Fast Open, from Jerry Chu and others.
      
       7) Packet BPF filter supports MOD and XOR, from Eric Dumazet and Daniel
          Borkmann.
      
       8) Increate the loopback default MTU to 64K, from Eric Dumazet.
      
       9) Use a per-task rather than per-socket page fragment allocator for
          outgoing networking traffic.  This benefits processes that have very
          many mostly idle sockets, which is quite common.
      
          From Eric Dumazet.
      
      10) Use up to 32K for page fragment allocations, with fallbacks to
          smaller sizes when higher order page allocations fail.  Benefits are
          a) less segments for driver to process b) less calls to page
          allocator c) less waste of space.
      
          From Eric Dumazet.
      
      11) Allow GRO to be used on GRE tunnels, from Eric Dumazet.
      
      12) VXLAN device driver, one way to handle VLAN issues such as the
          limitation of 4096 VLAN IDs yet still have some level of isolation.
          From Stephen Hemminger.
      
      13) As usual there is a large boatload of driver changes, with the scale
          perhaps tilted towards the wireless side this time around.
      
      Fix up various fairly trivial conflicts, mostly caused by the user
      namespace changes.
