br_fdb_changeaddr() assumes that there is at most one local entry per port
per vlan. It used to be true, but since commit 36fd2b63 ("bridge: allow
creating/deleting fdb entries via netlink"), it has not been so.
Therefore, the function might fail to search a correct previous address
to be deleted and delete an arbitrary local entry if user has added local
entries manually.

Example of problematic case:
  ip link set eth0 address ee:ff:12:34:56:78
  brctl addif br0 eth0
  bridge fdb add 12:34:56:78:90:ab dev eth0 master
  ip link set eth0 address aa:bb:cc:dd:ee:ff
Then, the address 12:34:56:78:90:ab might be deleted instead of
ee:ff:12:34:56:78, the original mac address of eth0.

Address this issue by introducing a new flag, added_by_user, to struct
net_bridge_fdb_entry.

Note that br_fdb_delete_by_port() has to set added_by_user to 0 in cases
like:
  ip link set eth0 address 12:34:56:78:90:ab
  ip link set eth1 address aa:bb:cc:dd:ee:ff
  brctl addif br0 eth0
  bridge fdb add aa:bb:cc:dd:ee:ff dev eth0 master
  brctl addif br0 eth1
  brctl delif br0 eth0
In this case, kernel should delete the user-added entry aa:bb:cc:dd:ee:ff,
but it also should have been added by "brctl addif br0 eth1" originally,
so we don't delete it and treat it a new kernel-created entry.

FIN_WAIT2 timeout for ages (since 2.x times??).

In any case, the timeout these days is 60 seconds, so the 3 min

The patch 446fab59 ("ipv6: enable anycast addresses
as source addresses in ICMPv6 error messages") causes an Oops when pinging a not
set up IPv6 peer on a sit tunnel.

The problem is that ipv6_anycast_destination() uses unconditionally skb_dst(skb),
which is NULL in this case.

The solution is to use instead the ipv6_chk_acast_addr_src() function.

Here are the steps to reproduce it:
modprobe sit
ip link add sit1 type sit remote 10.16.0.121 local 10.16.0.249
ip l s sit1 up
ip -6 a a dev sit1 2001:1234::123 remote 2001:1234::121

John W. Linville says:

====================
Please pull this batch of fixes intended for the 3.14 stream!

For the mac80211 bits, Johannes says:

"This is just a collection of small fixes, the commit logs explain the
details. The only thing that isn't strictly a fix is the 5/10 MHz
enabling, I had forgotten this and there's little point in waiting
longer. The patch simply removes the force-disable code that I put in
when there was a problem with the userspace API (that has long been
fixed.)"

For the iwlwifi bits, Emmanuel says:

"I have an important fix that disables A band in case the driver thought
it was enabled, and the firmware disagreed. We ended up making the
firmware unhappy. I also fix the station table in AP mode and fix the
scan while we have BT working.
Johannes removes a static variable that could potentially lead to to
issues on multi-device setups and disables scheduled scan to avoid
issues with old versions of wpa_supplicant.
A small fix from David on scan and a few new device IDs for 7265."

On top of that...

Oleksij Rempel adds a USB ID to the ar5523 driver and changes the
default powersave setting for ath9k_htc to "off", due to observed
stability issues (based on an equivalent ath9k patch).

Stanislaw Gruszka similarly disables powersave for a couple of rt2x00
drivers.  He also fixes a couple of scheduling while atomic issues
in ath9k_htc.

Sujith Manoharan rounds-out the powersave disables with one for ath9k.
He also fixes a build prolem with ath9k on ARM and fixes an ath9k Tx
power calculation.

Finally, Andrea Merello fixes a couple of lingering DMA mapping
problems in the rtl8180 driver.

Netfilter/nftables/IPVS fixes for net

The following patchset contains Netfilter/IPVS fixes, mostly nftables
fixes, most relevantly they are:

* Fix a crash in the h323 conntrack NAT helper due to expectation list
  corruption, from Alexey Dobriyan.

* A couple of RCU race fixes for conntrack, one manifests by hitting BUG_ON
  in nf_nat_setup_info() and the destroy path, patches from Andrey Vagin and
  me.

* Dump direction attribute in nft_ct only if it is set, from Arturo
  Borrero.

* Fix IPVS bug in its own connection tracking system that may lead to
  copying only 4 bytes of the IPv6 address when initializing the
  ip_vs_conn object, from Michal Kubecek.

* Fix -EBUSY errors in nftables when deleting the rules, chain and tables
  in a row due mixture of asynchronous and synchronous object releasing,
  from me.

* Three fixes for the nf_tables set infrastructure when using intervals and
  mappings, from me.

* Four patches to fixing the nf_tables log, reject and ct expressions from
  the new inet table, from Patrick McHardy.

* Fix memory overrun in the map that is used to dynamically allocate names
  from anonymous sets, also from Patrick.

* Fix a potential oops if you dump a set with NFPROTO_UNSPEC and a table
  name, from Patrick McHardy.

Fix access to uninitialized data for end interval elements. The
element data part is uninitialized in interval end elements.
Signed-off-by: NPablo Neira Ayuso <pablo@netfilter.org>

This patch fixes several things which related to the handling of
end interval elements:

* Chain use underflow with intervals and map: If you add a rule
  using intervals+map that introduces a loop, the error path of the
  rbtree set decrements the chain refcount for each side of the
  interval, leading to a chain use counter underflow.

* Don't copy the data part of the end interval element since, this
  area is uninitialized and this confuses the loop detection code.

* Don't allocate room for the data part of end interval elements
  since this is unused.

So, after this patch the idea is that end interval elements don't
have a data part.

TCP pacing depends on an accurate srtt estimation.

Current srtt estimation is using jiffie resolution,
and has an artificial offset of at least 1 ms, which can produce
slowdowns when FQ/pacing is used, especially in DC world,
where typical rtt is below 1 ms.

We are planning a switch to usec resolution for linux-3.15,
but in the meantime, this patch removes the 1 ms offset.

All we need is to have tp->srtt minimal value of 1 to differentiate
the case of srtt being initialized or not, not 8.

The problematic behavior was observed on a 40Gbit testbed,
where 32 concurrent netperf were reaching 12Gbps of aggregate
speed, instead of line speed.

This patch also has the effect of reporting more accurate srtt and send
rates to iproute2 ss command as in :

sock_alloc_send_pskb() & sk_page_frag_refill()
have a loop trying high order allocations to prepare
skb with low number of fragments as this increases performance.

Problem is that under memory pressure/fragmentation, this can
trigger OOM while the intent was only to try the high order
allocations, then fallback to order-0 allocations.

We had various reports from unexpected regressions.

According to David, setting __GFP_NORETRY should be fine,
as the asynchronous compaction is still enabled, and this
will prevent OOM from kicking as in :

This is a static checker fix, but judging from the context then I think
hexidecimal 0x80 is intended here instead of decimal 80.

commit 	efe4208f:
'ipv6: make lookups simpler and faster' broke initialization of local source
address on accepted ipv6 sockets. Before the mentioned commit receive address
was copied along with the contents of ipv6_pinfo in sctp_v6_create_accept_sk.
Now when it is moved, it has to be copied separately.

This also fixes lksctp's ipv6 regression in a sense that test_getname_v6, TC5 -
'getsockname on a connected server socket' now passes.

The submission of the interrupt transfer should be done after setting
the bit of WORK_ENABLE, otherwise the callback function would have
the opportunity to be returned directly.

Clear the bit of WORK_ENABLE before killing the interrupt transfer.

bnx2x driver uses incorrect PF identifier to configure (in HW) the VF
interrupt scheme; As a result, in multi-function mode the configuration
for PFs with a high index (4+) will overflow and the PF will erroneously
configure a single ISR scheme for its VFs.
As a result, if such a VF uses multiple queues, interrupt generation will
stop after VF receives an Rx packet or sends a Tx packet on a queue
other than queue[0].

Quoting David Vrabel -
"5780 cards cannot have jumbo frames and TSO enabled together.  When
jumbo frames are enabled by setting the MTU, the TSO feature must be
cleared.  This is done indirectly by calling netdev_update_features()
which will call tg3_fix_features() to actually clear the flags.

netdev_update_features() will also trigger a new netlink message for the
feature change event which will result in a call to tg3_get_stats64()
which deadlocks on the tg3 lock."

tg3_set_mtu() does not need to be under the tg3 lock since converting
the flags to use set_bit(). Move it out to after tg3_netif_stop().
