This changes ensures that the routing entry investigated by the suppress
function actually does point to a device struct before following that pointer,
fixing a possible kernel oops situation when verifying the interface group
associated with a routing table entry.

According to Daniel Golle, this Oops can be triggered by a user process trying
to establish an outgoing IPv6 connection while having no real IPv6 connectivity
set up (only autoassigned link-local addresses).

Brett Ciphery reported that new ipv6 addresses failed to get installed
because the addrconf generated dsts where counted against the dst gc
limit. We don't need to count those routes like we currently don't count
administratively added routes.

Because the max_addresses check enforces a limit on unbounded address
generation first in case someone plays with router advertisments, we
are still safe here.

====================
The following patchset contains three Netfilter fixes for your net tree,
they are:

* fix incorrect comparison in the new netnet hash ipset type, from
  Dave Jones.

* fix splat in hashlimit due to missing removal of the content of its
  proc entry in netnamespaces, from Sergey Popovich.

* fix missing rule flushing operation by table in nf_tables. Table
  flushing was already discussed back in October but this got lost and
  no patch has hit the tree to address this issue so far, from me.

Commit e40526cb introduced a cached dev pointer, that gets
hooked into register_prot_hook(), __unregister_prot_hook() to
update the device used for the send path.

We need to fix this up, as otherwise this will not work with
sockets created with protocol = 0, plus with sll_protocol = 0
passed via sockaddr_ll when doing the bind.

So instead, assign the pointer directly. The compiler can inline
these helper functions automagically.

While at it, also assume the cached dev fast-path as likely(),
and document this variant of socket creation as it seems it is
not widely used (seems not even the author of TX_RING was aware
of that in his reference example [1]). Tested with reproducer
from e40526cb.

In (32263dd1 netfilter: xt_hashlimit: fix namespace destroy path)
the hashlimit_net_exit() function is always called right before
hashlimit_mt_destroy() to release netns data. If you use xt_hashlimit
with IPv4 and IPv6 together, this produces the following splat via
netconsole in the netns destroy path:

br_stp_rcv() is reached by non-rx_handler path. That means there is no
guarantee that dev is bridge port and therefore simple NULL check of
->rx_handler_data is not enough. There is need to check if dev is really
bridge port and since only rcu read lock is held here, do it by checking
->rx_handler pointer.

Note that synchronize_net() in netdev_rx_handler_unregister() ensures
this approach as valid.

Introduced originally by:
commit f350a0a8
  "bridge: use rx_handler_data pointer to store net_bridge_port pointer"

Fixed but not in the best way by:
commit b5ed54e9
  "bridge: fix RCU races with bridge port"

Reintroduced by:
commit 716ec052
  "bridge: fix NULL pointer deref of br_port_get_rcu"

Please apply to stable trees as well. Thanks.

We must clear local_df when passing the skb between namespaces as the
packet is not local to the new namespace any more and thus may not get
fragmented by local rules. Fred Templin noticed that other namespaces
do fragment IPv6 packets while forwarding. Instead they should have send
back a PTB.

The same problem should be present when forwarding DF-IPv4 packets
between namespaces.

kill memcg_tcp_enter_memory_pressure.  The only function of
memcg_tcp_enter_memory_pressure was to reduce deal with the
unnecessary abstraction that was tcp_memcontrol.  Now that struct
tcp_memcontrol is gone remove this unnecessary function, the
unnecessary function pointer, and modify sk_enter_memory_pressure to
set this field directly, just as sk_leave_memory_pressure cleas this
field directly.

This fixes a small bug I intruduced when killing struct tcp_memcontrol
that caused memcg_tcp_enter_memory_pressure to never be called and
thus failed to ever set cg_proto->memory_pressure.

Remove the cg_proto enter_memory_pressure function as it now serves
no useful purpose.

Don't test cg_proto->memory_presser in sk_leave_memory_pressure before
clearing it.  The test was originally there to ensure that the pointer
was non-NULL.  Now that cg_proto is not a pointer the pointer does not
matter.

When I install the bonding with the wrong arp_ip_target,
just like arp_ip_target=500.500.500.500, the arp_ip_target
was transfored to 245.245.245.244 and stored in the ip
target success, it is uncorrect, so I add checks to avoid
adding wrong address.

The in4_pton() will set wrong ip address to 0.0.0.0 and
return 0, also use the micro IS_IP_TARGET_UNUSABLE_ADDRESS
to simplify the code.

As Michael pointed out that when max_burst is 0, it just disable
max_burst. It declared in rfc6458#section-8.1.24. so add the check
in sctp_transport_burst_limited, when it 0, just do nothing.

When booted with device tree, we may still have platform data passed
as auxdata. For am3517 this is needed for passing the interrupt_enable
and interrupt_disable callbacks that access the omap system control module
registers. These callback functions will eventually go away when we have
a separate system control module driver.

Some of the things that are currently passed as platform data we don't need
to set up as device tree properties as they are always the same on am3517.
So let's use a new compatible flag for those so we can get those from
the device tree match data.

Also note that we need to fix setting of phy_dev to NULL instead of an empty
string as the code later on uses that to find the first phy on the mdio bus.
This seems to have been caused by 5d69e007 (net: davinci_emac: switch to
new mdio).

The code to detect fragments in checksum_setup() was missing for IPv4 and
too eager for IPv6. (It transpires that Windows seems to send IPv6 packets
with a fragment header even if they are not a fragment - i.e. offset is zero,
and M bit is not set).

This patch also incorporates a fix to callers of maybe_pull_tail() where
skb->network_header was being erroneously added to the length argument.

====================
Please pull this batch of fixes intende for the 3.13 stream!

For the mac80211 bits, Johannes says:

"For now I have various fixes all over, mostly for issues introduced in
relatively recent patches. There's no real pattern to it. Some of the
issues like go back longer, but still seemed 3.13 material."

And...

"These are just two patches disabling the broken CSA code. Once this
goes into your tree I'll merge it into mac80211-next and revert there
(since we fixed the bugs there)."

For the iwlwifi bits, Emmanuel says:

"I have here a few fixes for BT Coex. One of them is a NULL pointer
dereference. Another one avoids to enable a feature that can make the
firmware unhappy since the firmware isn't ready for it yet. WE also
avoid a WARNING that can be triggered upon association in not-so-bad
cases even if the association succeeded. We add support for new NICs
(not yet on the market) and bump the API so that 3.13 will be able to
work with the new firmware that will be out soon hopefully.
I also have a boundary check from Johannes."

In addition to those...

- Arend van Spriel fixes a brcmfmac problem that could use an
uninitialized variable in an error path.

- Borislav Petkov fixes a Kconfig-based build breakage problem for
brcmsmac.

- Michal Nazarewicz fixes a couple of NULL pointer dereference problems
in ath9k and wcn36xx.

- Sujith Manoharan fixes a couple of ath9k problems related to
incorrect interpretation of EEPROM configuration data.

- Ujjal Roy fixes a memory leak in mwifiex.

Fixes T5 adapter init, due to incorrect FW version check

This patch series fixes, Chelsio T5 adapter initialization failure due to
incorrect firmware version check. This patch series modifies the firmware
flashing mechanism for T4/T5 adapter.

The patch series moves chip type from struct adapter to struct adapter_params.
It changes the references of chip type in cxgb4 and cxgb4vf drivers such that
build failure is avoided.

Patch 3/3 is dependent on patch 1/3
Patch 2/3 is also dependent on patch 1/3

We would like to request this patch series to get merged via David Miller's
'net' tree.

We have included all the maintainers of respective drivers. Kindly review the
change and let us know in case of any review comments.
