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 :

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 :

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().

In the original code, if tg3_readphy() fails then it does an unnecessary
check to verify "err" is still zero and then returns -EBUSY.

My static checker complains about the unnecessary "if (!err)" check and
anyway it is better to propagate the -EBUSY error code from
tg3_readphy() instead of hard coding it here.  And really the original
code is confusing to look at.

Adding some debugging code reveals that net_fill_ifaddr() fails in

    put_cacheinfo(skb, ifa->ifa_cstamp, ifa->ifa_tstamp,
                              preferred, valid))

nla_put complains:

    lib/nlattr.c:454: skb_tailroom(skb) = 12, nla_total_size(attrlen) = 20

Apparently commit 5c766d64 ("ipv4:
introduce address lifetime") forgot to take into account the addition of
struct ifa_cacheinfo in inet_nlmsg_size(). Hence add it, like is already
done for ipv6.

Occasionally users want to know what parameters their Broadcom drivers
are running with. For example, a user may want to know if MSI is
disabled.

This patch has been compile tested.

This patch removes old and unsupported CLPS711X IrDA driver.
Support for IrDA for CLPS711X serial port now provided by commit
4a33f1f59abd (serial: clps711x: Add support for N_IRDA line
discipline), so IrDA-mode can be turned ON with "irattach" tool
through "irtty" driver.

Switch the device tree to the new compatibles introduced in the ethernet and

The Allwinner A10 compatibles were following a slightly different compatible
patterns than the rest of the SoCs for historical reasons. Add compatibles
matching the other pattern to the mdio driver for consistency, and keep the
older one for backward compatibility.

Orignal code will not detect a DMA mapping failure, causing the HW
to attempt a DMA from an invalid address.

This patch add the error check and eventually simply drops the TX
packet if we can't map it for DMA.

In original code the old RX DMA buffer is unmapped and processed and at the end
of the isr a new buffer is mapped with pci_map_single and attached to the RX
descriptor.

If pci_map_single fails then the RX descriptor remains with no valid DMA buffer
attached.
In this condition the DMA will target where it shouldn't with obvious evil
consequences.

Simply avoiding re-arming the descriptor will prevent buggy DMA but it will
result soon in RX stuck.

This patch move the DMA mapping of the new buffer at the beginning of the ISR
(and it adds error check for pci_map_single success/fail).

If the DMA mapping fails then we do not unmap the old buffer and we re-arm the
descriptor without processing it, with the old DMA buffer still attached.

In this way we lose the currently RX-ed packet, but whenever next calls to
pci_map_single will succeed again,then the RX process will go on without stuck.
