The patch 446fab5933 ("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
ping6 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: Pablo 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 :
$ ss -i dst cca2
