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.

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.

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.

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.

When an address is added on loopback (ip -6 a a 2002::1/128 dev lo), a route
to fe80::/64 is added in the main table:
  unreachable fe80::/64 dev lo  proto kernel  metric 256  error -101

This route does not match any prefix (no fe80:: address on lo). In fact,
addrconf_dev_config() will not add link local address because this function
filters interfaces by type. If the link local address is added manually, the
route to the link local prefix will be automatically added by
addrconf_add_linklocal().
Note also, that this route is not deleted when the address is removed.

After looking at the code, it seems that addrconf_add_lroute() is redundant with
addrconf_add_linklocal(), because this function will add the link local route
when the link local address is configured.

Pull pinctrl changes from Linus Walleij:
 "Some of this stuff is hitting arch/arm/* and have been ACKed by the
  ARM SoC folks, or it's device tree bindings pertaining to the specific
  driver.

  These are the bulk pinctrl changes for kernel v3.7:
   - Add subdrivers for the DB8540 and NHK8815 Nomadik-type ASICs,
     provide platform config for the Nomadik.
   - Add a driver for the i.MX35.
   - Add a driver for the BCM2835, an advanced GPIO expander.
   - Various fixes and clean-ups and minor improvements for the core,
     Nomadik, pinctr-single, sirf drivers.
   - Some platform config for the ux500."

Pull GPIO changes from Linus Walleij:
 "So this is the LW GPIO patch stack for v3.7:
   - 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."

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.

Pull sparc updates from David Miller:
 "Largely this is simply adding support for the Niagara 4 cpu.

  Major areas are perf events (chip now supports 4 counters and can
  monitor any event on each counter), crypto (opcodes are availble for
  sha1, sha256, sha512, md5, crc32c, AES, DES, CAMELLIA, and Kasumi
  although the last is unsupported since we lack a generic crypto layer
  Kasumi implementation), and an optimized memcpy.

  Finally some cleanups by Peter Senna Tschudin."
