e07db352ca ath10k: add back enum ath10k_bus
Commit 3a0861fffd ("ath10k: remove ath10k_bus") removed enum ath10k_bus
because it was not used for anything at the time. But now it's needed for for
retrieving the right calibration data file so add it back. Only new addition is
ath10k_bus_str().

82d7aba715 ath10k: fix kernel panic while shutting down AP
Based on GFP flag given to DMA coherent allocation, the behaviour of
dma_free_coherent is changed. This behavioural diffrence is noticeable
in ARM platform. If DMA memory is allocated with GFP_KERNEL, free
coherent can not be called inside spin lock. This is causing kernel
crash in ARM platforms. Fix this by changing GFP flag to atomic.

This is most likely a regression from commit 64badcb6d6 ("ath10k: workaround
fw beaconing bug").

====================
pull request: wireless-next 2014-10-09

Please pull this batch of fixes intended for the 3.18 stream!

Andrea Merello makes rtl818x_pci use a more reasonable transmission
rate for HW generated frames.

Fabian Frederick tweaks some kernel-doc bits to avoid warnings.

Larry Finger corrects a possible unaligned access in the rtlwifi code.

Marek Puzyniak avoids a kernel panic in ath9k_hw_reset.

Sujith Manoharan goes for the hat trick -- he fixes a smatch warning
in the shared ath code, he fixes a crash in ath9k, and he corrects
a sequence number assignment problem in ath9k too.

For ease of merging, I pulled the last bits of the wireless tree as well...

Please let me know if there are problems!

Pull networking updates from David Miller:
 "Most notable changes in here:

   1) By far the biggest accomplishment, thanks to a large range of
      contributors, is the addition of multi-send for transmit.  This is
      the result of discussions back in Chicago, and the hard work of
      several individuals.

      Now, when the ->ndo_start_xmit() method of a driver sees
      skb->xmit_more as true, it can choose to defer the doorbell
      telling the driver to start processing the new TX queue entires.

      skb->xmit_more means that the generic networking is guaranteed to
      call the driver immediately with another SKB to send.

      There is logic added to the qdisc layer to dequeue multiple
      packets at a time, and the handling mis-predicted offloads in
      software is now done with no locks held.

      Finally, pktgen is extended to have a "burst" parameter that can
      be used to test a multi-send implementation.

      Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4,
      virtio_net

      Adding support is almost trivial, so export more drivers to
      support this optimization soon.

      I want to thank, in no particular or implied order, Jesper
      Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal
      Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann,
      David Tat, Hannes Frederic Sowa, and Rusty Russell.

   2) PTP and timestamping support in bnx2x, from Michal Kalderon.

   3) Allow adjusting the rx_copybreak threshold for a driver via
      ethtool, and add rx_copybreak support to enic driver.  From
      Govindarajulu Varadarajan.

   4) Significant enhancements to the generic PHY layer and the bcm7xxx
      driver in particular (EEE support, auto power down, etc.) from
      Florian Fainelli.

   5) Allow raw buffers to be used for flow dissection, allowing drivers
      to determine the optimal "linear pull" size for devices that DMA
      into pools of pages.  The objective is to get exactly the
      necessary amount of headers into the linear SKB area pre-pulled,
      but no more.  The new interface drivers use is eth_get_headlen().
      From WANG Cong, with driver conversions (several had their own
      by-hand duplicated implementations) by Alexander Duyck and Eric
      Dumazet.

   6) Support checksumming more smoothly and efficiently for
      encapsulations, and add "foo over UDP" facility.  From Tom
      Herbert.

   7) Add Broadcom SF2 switch driver to DSA layer, from Florian
      Fainelli.

   8) eBPF now can load programs via a system call and has an extensive
      testsuite.  Alexei Starovoitov and Daniel Borkmann.

   9) Major overhaul of the packet scheduler to use RCU in several major
      areas such as the classifiers and rate estimators.  From John
      Fastabend.

  10) Add driver for Intel FM10000 Ethernet Switch, from Alexander
      Duyck.

  11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric
      Dumazet.

  12) Add Datacenter TCP congestion control algorithm support, From
      Florian Westphal.

  13) Reorganize sk_buff so that __copy_skb_header() is significantly
      faster.  From Eric Dumazet"

QoS-data frames are handled properly since they

79ee65659e rtl818x_pci: fix response rate may be incorrect.
Currently the allowed "respose rate" set (rates for HW generated frames
like ACKs) is the same as the basic rate set.

The HW will use the higher allowed response rate that is lower than the
rate of the received frame.

This is more or less what IEEE80211 mandates, but I missed the fact
that IEEE80211 also says that whenever it happens that for a modulation
class there is no any rate in the basic rates set, then the response rate
set shall include also all the mandatory rates for that modulation class.

This patch adds mandatory OFDM rates to the allowed response rate set if
no OFDM rate is included in the basic rate set.

Depending by the AP, I faced cases in which this patch seems to cause a
noticeable perfomance improvement.

- With my usual test AP there is no particular perfomance difference.
- With a prism54/hostapd AP this patch causes RX thoughput increase from
  about 5Mbps to about 20Mbps.

Hopefully this patch may help people that faced performance regression wrt
the old staging driver.

- DT properties additions to handle different quirks
- A bunch of fixes for smartphone IOP related issues

For ST Microelectronics' ST21NFCA and ST21NFCB drivers:

- ISO15693 support for st21nfcb
- checkpatch and sparse related warning fixes
- Code cleanups and a few minor fixes

Finally, Marvell added ISO15693 support to the NCI stack, together with a
couple of NCI fixes."

For the Bluetooth bits, Johan says:

"This 3.18 pull request replaces the one I did on Monday ("bluetooth-next
2014-09-22", which hasn't been pulled yet). The additions since the last
request are:

 - SCO connection fix for devices not supporting eSCO
 - Cleanups regarding the SCO establishment logic
 - Remove unnecessary return value from logging functions
 - Header compression fix for 6lowpan
 - Cleanups to the ieee802154/mrf24j40 driver

Here's a copy from previous request that this one replaces:

'
Here are some more patches for 3.18. They include various fixes to the
btusb HCI driver, a fix for LE SMP, as well as adding Jukka to the
MAINTAINERS file for generic 6LoWPAN (as requested by Alexander Aring).

I've held on to this pull request a bit since we were waiting for a SCO
related fix to get sorted out first. However, since the merge window is
getting closer I decided not to wait for it. If we do get the fix sorted
out there'll probably be a second small pull request later this week.
'"

And,

"Unless 3.17 gets delayed this will probably be our last -next pull request for
3.18. We've got:

  - New Marvell hardware supportr
  - Multicast support for 6lowpan
  - Several of 6lowpan fixes & cleanups
  - Fix for a (false-positive) lockdep warning in L2CAP
  - Minor btusb cleanup"

On top of all that comes the usual sort of updates to ath5k, ath9k,
ath10k, brcmfmac, mwifiex, and wil6210.  This time around there are
also a number of rtlwifi updates to enable some new hardware and
to reconcile the in-kernel drivers with some newer releases of the
Realtek vendor drivers.  Also of note is some device tree work for
the bcma bus.

Please let me know if there are problems!

e2cba8d759 ath9k: Fix flushing in MCC mode
When we are attempting to switch to a new
channel context, the TX queues are flushed, but
the mac80211 queues are not stopped and traffic
can still come down to the driver.

This patch fixes it by stopping the queues

5ba8d9d2f0 ath9k: Fix queue handling for channel contexts
When a full chip reset is done, all the queues
across all VIFs are stopped, but if MCC is enabled,
only the queues of the current context is awakened,
when we complete the reset.

This results in unfairness for the inactive context.
Since frames are queued internally in the driver if
there is a context mismatch, we can awaken all the
queues when coming out of a reset.

The VIF-specific queues are still used in flow control,
to ensure fairness when traffic is high.

It might also have been causing other stability issues because of the

changed to kzalloc and vzalloc. The change fixes a problem that was causing
HT operations to be cancelled.

8084bb0369 rtl818x_pci: add RSSI information for rtl8187SE
This patch makes the driver to report signal strength information
to mac80211 for rtl8187se boards.

It differs from my previous RFT patch:
http://marc.info/?l=linux-wireless&m=140155388332534&w=2
because:
- I have now a working rtl8187se card, so I could serve my RFT by myself. :)
- CCK measurement code has changed a bit, but it does basically the same things.
- OFDM measurement method is changed because the older method reported incorrect
  measures, at least for signals stronger than -40dBm).

CCK measurement seems quite good. OFDM seems less accurate, but this is the
same as the "reference" staging driver dose. I wanted not to change things just
to make measures of _one_ (my) card a bit more close to what _I_ (in my setup)
expected..

IMHO results are still good enough to justify reporting signal in dBm rather than in
"unspecified" units, so this is what this patch actually does.

Results of my tests with a working rtl8187se card connected with coaxes and
various RF attenuators to my AP are:

Input (approx) | CCK meas | OFDM meas
--------------------------------------
      -30dBm   |  -32dBm  |  -31dBm
      -40dBm   |  -40dBm  |  -41dBm
      -50dBm   |  -50dBm  |  -55dBm
      -60dBm   |  -59dBm  |  -63dBm
      -70dBm   |  -69dBm  |  -73dBm
      -80dBm   |  -79dBm  |  -83dBm

Also some real-field tests has been done (no coax, packets in the air) for the CCK
measure method, and they resulted in reasonable values.

Certain frames like provision requests use the device address

device address is not used.

John W. Linville says:

====================
pull request: wireless-next 2014-09-22

Please pull this batch of updates intended for the 3.18 stream...

For the mac80211 bits, Johannes says:

"This time, I have some rate minstrel improvements, support for a very
small feature from CCX that Steinar reverse-engineered, dynamic ACK
timeout support, a number of changes for TDLS, early support for radio
resource measurement and many fixes. Also, I'm changing a number of
places to clear key memory when it's freed and Intel claims copyright
for code they developed."

For the bluetooth bits, Johan says:

"Here are some more patches intended for 3.18. Most of them are cleanups
or fixes for SMP. The only exception is a fix for BR/EDR L2CAP fixed
channels which should now work better together with the L2CAP
information request procedure."

For the iwlwifi bits, Emmanuel says:

"I fix here dvm which was broken by my last pull request. Arik
continues to work on TDLS and Luca solved a few issues in CT-Kill. Eyal
keeps digging into rate scaling code, more to come soon. Besides this,
nothing really special here."

Beyond that, there are the usual big batches of updates to ath9k, b43,
mwifiex, and wil6210 as well as a handful of other bits here and there.
Also, rtlwifi gets some btcoexist attention from Larry.

Please let me know if there are problems!

AHB bus support was added in v2.6.38, through commit a0b907ee2a
("ath5k: Add AHB bus support."). That code can only be build if the
Kconfig symbol ATHEROS_AR231X is set. But that symbol has never been
added to the tree. So AHB bus support has always been dead code.

Let's remove all code that depends on ATHEROS_AR231X. If that symbol
ever gets added to the tree the AHB bus support can be re-added too.

f8adaf0ae9 brcmfmac: Fix off by one bug in brcmf_count_20mhz_channels()
In the brcmf_count_20mhz_channels function we are looping through a list
of channels received from firmware. Since the index of the first channel
is 0 the condition leads to an off by one bug. This is causing us to hit
the WARN_ON_ONCE(1) calls in the brcmu_d11n_decchspec function, which is
how I discovered the bug.

64badcb6d6 ath10k: workaround fw beaconing bug
Some firmware revisions don't wait for beacon tx
completion before sending another SWBA event. This
could lead to hardware using old (freed) beacon
data in some cases, e.g. tx credit starvation
combined with missed TBTT. This is very very rare.

On non-IOMMU-enabled hosts this could be a
possible security issue because hw could beacon
some random data on the air.  On IOMMU-enabled
hosts DMAR faults would occur in most cases and
target device would crash.

Since there are no beacon tx completions (implicit
nor explicit) propagated to host the only
workaround for this is to allocate a DMA-coherent
buffer for a lifetime of a vif and use it for all
beacon tx commands. Worst case for this approach
is some beacons may become corrupted, e.g. garbled
IEs or out-of-date TIM bitmap.

Keep the original beacon-related code as-is in
case future firmware revisions solve this problem
so that the old path can be easily re-enabled with
a fw_feature flag.

statistics of sent vs. acked of such a BA. This can improve the
reaction time of the RS algorithm. Also, an upcoming change in
the firmware would cause BA timeout to be reported as a BA notif
with 0 acked so this change is required for that as well.

3edf8ff617 iwlwifi: mvm: prepare for scheduler config command
The scheduler is a HW sub-block that directs the work of the Flow
Handler by issuing requests for frame transfers, specifying source
and destination. Its primary function is to allocate flows into the
TX FIFOs based upon a pre-determined mapping.

The driver has some responsibilities to the scheduler, namely
initialising and maintaining the hardware registers. This is
currently done by directly accessing them, which can cause races
with the firmware also accessing the registers.

To address this problem, change the driver to no longer directly
access the registers but go through the firmware for this if the
firmware has support for DQA and thus the new command.

d21ccfd0a6 ath9k_htc: fix random decryption failure
In v3.15 the driver stopped to accept network packets after successful
authentification, which could be worked around by passing the
nohwcrypt=1 module parameter.  This was not reproducible by
everyone, and showed random behaviour in some tests.
It was caused by an uninitialized variable introduced
in 4ed1a8d4a2 ("ath9k_htc: use ath9k_cmn_rx_accept") and
used in 341b29b9cd ("ath9k_htc: use ath9k_cmn_rx_skb_postprocess").

87c4790330 brcmfmac: handle IF event for P2P_DEVICE interface
The firmware notifies about interface changes through the IF event
which has a NO_IF flag that means host can ignore the event. This
behaviour was introduced in the driver by:

  commit 2ee8382fc6
  Author: Arend van Spriel <arend@broadcom.com>
  Date:   Sat Aug 10 12:27:24 2013 +0200

      brcmfmac: ignore IF event if firmware indicates it

It turns out that the IF event for the P2P_DEVICE also has this
flag set, but the event should not be ignored in this scenario.
The mentioned commit caused a regression in 3.12 kernel in creation
of the P2P_DEVICE interface.

than the port limit is aggregated in this case. ex. 15 instead of

The reason is we have redundant port limit checks before current

a659c4306b mwifiex: fix 5G association failure after leaving 2.4G IBSS
When assocaiting to an AP , mwifiex set supported data rates
based on target AP's capability. For 5G AP(11a mode), a/n/ac mode
would possibly be set.
However, for some chips which dont support 11AC mode current config_bands
will be used instead.

For example, if we join an IBSS in 11b mode ,adapter->config_bands
will be set to 1(11b mode). Then we leave IBSS ,and try to connect
5G a/n mode AP. At this time , only 11b mode data rates will be
supported in assoc request , which result in assoc failure with
reason code 18: Association denied due to requesting station not
supporting all rates.

This patch fix such a cornel case, by adding additional check for
current chip's 11ac capability.

When interfaces of different types are present
in a context and an offchannel request is received
on a STA interface, we end up trying to process
beacons received when we are offchannel. This hits
the below warning since offchannel will not have proper
beacon parameters.

Fix this by not processing beacons received when we

Skip over dtim was capped by 300TU where it should be by 306TU.
It should also be subjected to several conditions:
Not a DFS channel, dtim period < 10, and the multicast wake-lock
is off.  Concerning multicast lock - there is an implementation gap

Reading the temperature directly from the hardware, without the help
of the firmware, is a complex process and is not entirely the same for
different hardware.  Also, some NICs don't easily allow access to the
sensors when the firmware is not running, which would add even more
complexity to the code.

To reduce the code complexity and to avoid code duplication between
the firmware and the driver, boot the firmware briefly to read the
current temperature while in CT kill mode.

a bad memory dereference.

Different crashes decode in different manners, so
this will help the crash-report testing as well as
offer better ways to test firmware failure and
recovery.

43d2a30fa8 ath10k: add testmode
Add testmode interface for starting and using UTF firmware which is used to run
factory tests. This is implemented by adding new state ATH10K_STATE_UTF and user
space can enable this state with ATH10K_TM_CMD_UTF_START command. To go back to
normal mode user space can send ATH10K_TM_CMD_UTF_STOP.

167bf96dd8 ath9k: Fix beacon miss handling
The NoA duration for a GO is half the beacon interval
and a concurrent context like a STA can be active only
for that duration, before switching back to the GO's
operating channel.

Currently, when multiple beacons are missed, the dwell
time for the STA context is extended to improve the
chances of receiving a beacon. But the NoA is not updated
and this will cause problems since the GO is offline
for a period that is longer than the advertised duration.

Fix this by ensuring that the NoA is updated first before
extending the time slot for the STA context. Also make
sure that non-periodic NoA is used for a one-time, longer
absence period.

* The index has to incremented only when advertising

* Switch to non-periodic NoA when starting a scan operation

* Make sure that periodic NoA is advertised again when
  scan ends. Since the offchannel timer moves the offchannel

  active, use a flag "force_noa_update" to update the
  NoA contents.

[89846.807008] ---[ end trace d6fdc17cd27d18f6 ]---

Reason is the following: when removing Rx vring
(wil_netdev_ops.ndo_stop -> wil_stop -> wil_down -> __wil_down -> wil_rx_fini),
Rx interrupt occurs. It trigger Rx NAPI, calling wil_rx_handle() that reaps
(already cleaned) buffer, causing skb referring to garbage memory being set into reorder buffer.
Then, network stack trying to access this buffer and fails.

Prevent Rx NAPI from being scheduled if device going to stop. Bit wil_status_napi_en reflects
NAPI enablement state, check it when triggering Rx NAPI.

Testing shows that check for wil_status_napi_en sometimes gets negative, and new error message
get printed - in this case kernel oops would be observed. Original oops is no more reproducible.

This change requires also changes in the AP flows.
Properly enable/disable NAPI for the AP. Make sure Rx VRING is disabled
when resetting target.

For this, promote __wil_up() and __wil_down() to the module scope, and use it
in the relevant flows.

ae0fd63541 Revert "ath9k: Calculate sleep duration"
This reverts commit 09ebb81092.

ath9k_hw_set_sta_beacon_timers() configures AR_TIM_PERIOD with
the beacon interval. Before this commit, the sleepduration was
never greater than the beacon interval. But now, the behavior
has changed. For example, with an AP that uses a beacon interval of 100:

ath: phy9: next beacon 61128704
ath: phy9: beacon period 204800
ath: phy9: DTIM period 204800

If the sleepduration is calculated based on the listen time, then
the bmiss threshold should also be changed since the HW would
be in sleep state for a longer time, but that is not done currently.

To avoid configuring a higher beacon interval based on the sleepduration,
revert to the original behavior. Power consumption is not a
problem since PS is disabled in ath9k anyway.

367b341edb ath9k: Fix MCC scanning
Scanning is curently broken when two channel contexts
are active. For example in a P2P-GO/STA setup, the
offchannel timer allows HZ / 10 to elapse before initiating
a switch to the next scan channel from the current operating
channel, which in this case would be the P2P-GO context.

But, the channel context timer might decide to switch
to the STA context when an SWBA comes early and a beacon
is sent out. Since pending offchannel requests are processed
in EVENT_BEACON_PREPARE, this causes inconsistent scanning.

Fix this by making sure that a context switch happens
before processing the pending offchannel request. This
also makes sure that active channel contexts will always
have higher priority than offchannel operations and the
scan sequence looks like this:

p2p-go, sta, p2p-go, offchannel, p2p-go, sta, p2p-go, offchannel,.....

The oper-channel is p2p-go, so the STA context has to
switch to p2p-go again before switching offchannel.

updated based on the TSF timer when an absence notification
is sent by the P2P GO. When two channel contexts are active,
continuous, cyclic NoA is announced by setting the count value to 255,
but the start time is updated only once, for one beacon and
the same value is sent in all subsequent beacons, even
though the timestamp keeps moving.

and assign the interface's start_time/duration values directly
when there is more than one active context.

9bf30ff93d ath9k: Fix panic when adding an AP interface
If a station interface is already assigned to a context
and is active and a second interface of type AP is added,
then beaconing on the new interface has to be begin only
after the BSS_CHANGED_BEACON_ENABLED flag is sent by mac80211
to the driver.

But, since we issue ATH_CHANCTX_EVENT_ENABLE_MULTICHANNEL as soon
as a new channel context is added, a switch occurs almost immediately
before BSS_CHANGED_BEACON_ENABLED is received. When a HW reset
is done for the new context, beacons are enabled for the
interface since "enable_beacon" in the BSS config maintained
in mac80211 is true - but the driver hasn't been notified yet.
This causes a panic, since the beacon interval is zero for this
interface and ath9k_cmn_beacon_config_ap() doesn't have a safety check.

Fix this panic by checking if the beacon params has been cached
for this context and use the "enable_beacon" flag maintained
locally in the driver. Also, recalculate the summary data
after the beacon params have been cached when BSS_CHANGED_BEACON_ENABLED
is received.

12a1b3d4c3 ath9k: Fix beacon configuration for channel contexts
In channel context mode, when a new context is added,
mac80211 issues a bss_info_changed() notfication when
preparing the connection for the new interface/context.

But, this is done prior to the mgd_prepare_tx() call which
is where we switch to the new context. Since the current
context will be different when the earlier bss_info_changed()
is handled, the beacon information for the VIF is not
updated, but discarded since the rules for the current context
disallows it.

In the subsequent association process for the new context/vif,
this becomes a problem because the beacon parameters are invalid.
This causes problems with the TSF timer, causing large jumps.

To fix this, check if the beacon info is being updated for a
different context and if so, allow it without any checks since
we limit the max. interfaces to two anyway.

aa11bbf3df iwlwifi: mvm: treat EAPOLs like mgmt frames wrt rate
Using the LQ table which is initially set according to
the rssi could lead to EAPOLs being sent in high legacy
rates like 54mbps.
It's better to avoid sending EAPOLs in high rates as it reduces
the chances of a successful 4-Way handshake.
Avoid this and treat them like other mgmt frames which would
initially get sent at the basic rate.

The firmware would like to have a MAC context (unassoc)
before the AP station is removed (we do this) but would
like to keep the BSSID until after it is removed, so we
need to send two commands - one with the BSSID before
and one without the BSSID after.

In order to do this, we need to store the BSSID as it
will have been cleared by mac80211 by the time we get
notified of the disassociation. Also pass it around as
an override to the various functions needing it, and
keep taking it from the mac80211 data otherwise. This

84fd7608a0 iwlwifi: mvm: add use_ps-poll debugfs power option
By default, when uapsd is not used, the ucode uses
null data packet to exit power-save and get then
pending frames.

However, some tests require the explicit usage of ps-poll.
Allow setting use_ps_poll power option (through debugfs)
to configure the ucode to use ps-poll instead.

The ucode configuration is done by setting the advanced-pm
flag while setting all the ACs to non-upasd mode.

7ceb98a313 iwlwifi: mvm: reduce the AMPDU size in low latency mode
This allows to leave a frame in the Tx Fifo which allows
the firmware to try to enter burst mode.
The end result of this is a better latency since the
firmware utilises the TxOP better.

Also limit the AMPDU size to the limit set in the ADDBA
response. This doesn't change much since the AMPDU size
was limited by the configuration of the hardware scheduler,
but here we add a software limit by the mean of the link
quality command.

e75db4e368 ath10k: re-enable interrupts properly in hw recovery
Recent changes done to start/restart sequences
broke hw recovery in some hw configurations. The
pci transport was stopped twice however due to a
workaround in the pci disabling code the
disable/enable for first msi interrupt was not
balanced. This ended up with irqs not being
properly re-enabled and the following print out
during recovery:

 ath10k: failed to receive control response completion, polling..
 ath10k: Service connect timeout: -110
 ath10k: Could not init core: -110

Legacy interrupt mode was unaffected while msi
ranged mode would be partially crippled (it would
miss fw indication interrupts but otherwise it
worked fine).

This fixes completely broken fw recovery for a
single msi interrupt mode and fixes subsequent fw
crash reports for msi range interrupt mode.

6a5d088a92 carl9170: tx: Replace rcu_assign_pointer() with RCU_INIT_POINTER()
According to RCU_INIT_POINTER()'s block comment 3.a, it can be used if
"3.   The referenced data structure has already been exposed to readers either
at compile time or via rcu_assign_pointer() -and-
 a.   You have not made -any- reader-visible changes to this structure since
then".

This case fulfills the conditions above because between the rcu_dereference()
call (cvif = rcu_dereference(ar->beacon_iter);) and the rcu_assign_pointer()
call there is no update of the "cvif" variable.
Therefore, this patch makes the replacement.

The following Coccinelle semantic patch was used:
@@
identifier v;
@@

v = rcu_dereference(...);
... when != rcu_dereference(...);
    when != v = ...;
    when != (<+...v...+>)++;
    when != \(memcpy\|memset\)(...);
(
- rcu_assign_pointer
+ RCU_INIT_POINTER
  (..., v);
|
 if(...) {
... when != v = ...;
- rcu_assign_pointer
+ RCU_INIT_POINTER
  (..., v);
... when any
 }
)

Because there are cases where between a “rcu_dereference()” call and a
“rcu_assign_pointer()” call might be updates of the value that interests us,
the Coccinelle semantic patch ignores them and replaces with
"RCU_INIT_POINTER()" only when the update is not happening.

499afaccf6 ath9k: Isolate ath9k_use_chanctx module parameter
This patch ensures that the module parameter "use_chanctx" is
visible only when CONFIG_ATH9K_CHANNEL_CONTEXT is selected.
Also register the channel context callbacks with mac80211 only
when it is explicitly enabled and compile them out of the driver
when CONFIG_ATH9K_CHANNEL_CONTEXT is not selected.

ba1fa3cd61 ath9k_htc: advertise support for TDLS
Based on a quick test with AR9271, TDLS seems to be working fine.

Tests were done with 2 Atheros AR9271 based devices with firmware
1.3 (sha1 8d49f928aa40ac53c729189bff1333cd373a7fb5), associated
with a WAP54G access point. TDLS worked fine both in WPA2 mode and
without encryption. Stations maintained ping flood traffic between
each other and towards the AP without significant losses.

Not tested with AR7010.

TDLS was enabled in earlier patches the same way for other
Atheros drivers:
ath9k (fd6562344d),
and carl9170 (d1f3de71a5).

In the cfg80211_rx_mgmt(), parameter @gfp was used for the memory allocation.
But, memory get allocated under spin_lock_bh(), this implies atomic context.
So, one can't use GFP_KERNEL, only variants with no __GFP_WAIT. Actually, in all
occurrences GFP_ATOMIC is used (wil6210 use GFP_KERNEL by mistake),
and it should be this way or warning triggered in the memory allocation code.

Remove @gfp parameter as no actual choice exist, and use hard coded
GFP_ATOMIC for memory allocation.

ec76643b00 b43: implement PPR (Power Per Rate) management/API
Broadcom hardware supports auto-adjustment of TX power depending on the
currently used rate. So far all calculations were handled without any
helpers (API) using big arrays and magic offsets.
It seems Broadcom recently decided to clean this up by developing PPR.
Their wlc_ppr.h can be found in open parts of the SDK.
As we plan to implement support for rate-based TX power it makes sense
to also implement our version of PPR as well.

29e20aa6c6 at76c50x-usb: fix use after free on failure path in at76_probe()
After commit 174beab7d4 ("at76c50x-usb: Don't perform DMA from stack memory")
at76_delete_device() and usb_put_dev() are called both
if at76_init_new_device() fails in at76_probe().
But at76_delete_device() does usb_put_dev(priv->dev) itself
that means double usb_put_dev().

The patch avoids the problem by moving usb_put_dev() from
at76_delete_device() to at76_disconnect().

This fixes two corner cases.

One is a race between disabling copy engine

host. This could end up with a runaway tasklet and
consequently memory leak of a few copy engine
rx buffers.

The other one is an unexpected (and non-maskable
via device CSR) MSI fw indication interrupt during
teardown. This could trigger the same problem as
the first corner case.

5c81c7fd62 ath10k: introduce a stricter scan state machine
This aims at fixing some rare scan bugs related to
firmware reporting unexpected scan event
sequences.

One such bug was if spectral scan phyerr reporting
prevented firmware from properly propagating scan
events to host. This led to scan timeout. After
that next scan would trigger scan completed event
first (before scan started event) leading to
ar->scan.in_progress and timeout timer states to
be overwritten incorrectly and making the very
next scan to hang forever.

671796dd96 carl9170: fix sending URBs with wrong type when using full-speed
The driver assumes that endpoint 4 is always an interrupt endpoint.
Unfortunately the type differs between high-speed and full-speed
configurations while in the former case it is indeed an interrupt
endpoint this is not true for the latter case - here it is a bulk
endpoint. When sending URBs with the wrong type the kernel will
generate a warning message including backtrace. In this specific
case there will be a huge amount of warnings which can bring the system
to freeze.

To fix this we are now sending URBs to endpoint 4 using the type
found in the endpoint descriptor.

A side note: The carl9170 firmware currently specifies endpoint 4 as
interrupt endpoint even in the full-speed configuration but this has
no relevance because before this firmware is loaded the endpoint type
is as described above and after the firmware is running the stick is not
reenumerated and so the old descriptor is used.

Pull timer and time updates from Thomas Gleixner:
 "A rather large update of timers, timekeeping & co

   - Core timekeeping code is year-2038 safe now for 32bit machines.
     Now we just need to fix all in kernel users and the gazillion of
     user space interfaces which rely on timespec/timeval :)

   - Better cache layout for the timekeeping internal data structures.

   - Proper nanosecond based interfaces for in kernel users.

   - Tree wide cleanup of code which wants nanoseconds but does hoops
     and loops to convert back and forth from timespecs.  Some of it
     definitely belongs into the ugly code museum.

   - Consolidation of the timekeeping interface zoo.

   - A fast NMI safe accessor to clock monotonic for tracing.  This is a
     long standing request to support correlated user/kernel space
     traces.  With proper NTP frequency correction it's also suitable
     for correlation of traces accross separate machines.

   - Checkpoint/restart support for timerfd.

   - A few NOHZ[_FULL] improvements in the [hr]timer code.

   - Code move from kernel to kernel/time of all time* related code.

   - New clocksource/event drivers from the ARM universe.  I'm really
     impressed that despite an architected timer in the newer chips SoC
     manufacturers insist on inventing new and differently broken SoC
     specific timers.

[ Ed. "Impressed"? I don't think that word means what you think it means ]

   - Another round of code move from arch to drivers.  Looks like most
     of the legacy mess in ARM regarding timers is sorted out except for
     a few obnoxious strongholds.

   - The usual updates and fixlets all over the place"

Minor conflicts in iphc.c were changes overlapping with some

John W. Linville says:

====================
Please pull this last(?) batch of wireless change intended for the
3.17 stream...

For the NFC bits, Samuel says:

"This is a rather quiet one, we have:

- A new driver from ST Microelectronics for their NCI ST21NFCB,
  including device tree  support.

- p2p support for the ST21NFCA driver

- A few fixes an enhancements for the NFC digital laye"

For the Atheros bits, Kalle says:

"Michal and Janusz did some important RX aggregation fixes, basically we
were missing RX reordering altogether. The 10.1 firmware doesn't support
Ad-Hoc mode and Michal fixed ath10k so that it doesn't advertise Ad-Hoc
support with that firmware. Also he implemented a workaround for a KVM
issue."

For the Bluetooth bits, Gustavo and Johan say:

"To quote Gustavo from his previous request:

'Some last minute fixes for -next. We have a fix for a use after free in
RFCOMM, another fix to an issue with ADV_DIRECT_IND and one for ADV_IND with
auto-connection handling.  Last, we added support for reading the codec and
MWS setting for controllers that support these features.'

Additionally there are fixes to LE scanning, an update to conform to the 4.1
core specification as well as fixes for tracking the page scan state. All
of these fixes are important for 3.17."

And,

"We've got:

- 6lowpan fixes/cleanups
- A couple crash fixes, one for the Marvell HCI driver and another in LE SMP.
- Fix for an incorrect connected state check
- Fix for the bondable requirement during pairing (an issue which had
  crept in because of using "pairable" when in fact the actual meaning
  was "bondable" (these have different meanings in Bluetooth)"

Along with those are some late-breaking hardware support patches in
brcmfmac and b43 as well as a stray ath9k patch.

necessary APIs to proto, implements dummy functions in BCDC and
adds calls to proto wherever necessary by wl_cfg80211.

46de06839b brcmfmac: Do not use strcpy and strcat
Commit "c1b2053 brcmfmac: Make firmware path a module parameter"
introduced use of strcpy and strcat. The strcpy and strcat require
using null terminated strings and can cause out-of-bounds memory
access and subsequent corruption. This patch replaces these by
strncpy and strncat respectively to assure array boundaries are
not crossed.

John W. Linville says:

====================
pull request: wireless-next 2014-07-25

Please pull this batch of updates intended for the 3.17 stream!

For the mac80211 bits, Johannes says:

"We have a lot of TDLS patches, among them a fix that should make hwsim
tests happy again. The rest, this time, is mostly small fixes."

For the Bluetooth bits, Gustavo says:

"Some more patches for 3.17. The most important change here is the move of
the 6lowpan code to net/6lowpan. It has been agreed with Davem that this
change will go through the bluetooth tree. The rest are mostly clean up and
fixes."

and,

"Here follows some more patches for 3.17. These are mostly fixes to what
we've sent to you before for next merge window."

For the iwlwifi bits, Emmanuel says:

"I have the usual amount of BT Coex stuff. Arik continues to work
on TDLS and Ariej contributes a few things for HS2.0. I added a few
more things to the firmware debugging infrastructure. Eran fixes a
small bug - pretty normal content."

And for the Atheros bits, Kalle says:

"For ath6kl me and Jessica added support for ar6004 hw3.0, our latest
version of ar6004.

For ath10k Janusz added a printout so that it's easier to check what
ath10k kconfig options are enabled. He also added a debugfs file to
configure maximum amsdu and ampdu values. Also we had few fixes as
usual."

On top of that is the usual large batch of various driver updates --
brcmfmac, mwifiex, the TI drivers, and wil6210 all get some action.
Rafał has also been very busy with b43 and related updates.

Also, I pulled the wireless tree into this in order to resolve a
merge conflict...

P.S.  The change to fs/compat_ioctl.c reflects a name change in a
Bluetooth header file...

The 10.2 firmware is a successor of 10.1 firmware
(formerly identified as 10.x). Both share a lot
but have some slight ABI differences that need to
be taken care of.

The 10.2 firmware introduces some new features but
those can be added in subsequent patches. This
patch makes ath10k boot and work with 10.2 with
comparable functionality to 10.1.

0ccb7a3485 ath10k: handle attention flags correctly when using A-MSDU
In case of A-MSDU RX we should check attention flags
correctly to be sure we report correct FCS status for
A-MSDU subframes. Without a patch we could report A-MSDU
subframes with wrong FCS as a correct to the stack, next
get a lot of DUP ACK TCP packets. Finally TP drop is seen
and this drop depends on FCS errors ratio for A-MSDU frame.

Example test case when TP drop is seen:
- ath10k configured as an AP
- used ath10k station
- forced A-MSDU (7 frames) on STA
- other traffic on channel (often FCS errors)
- monitor iface added on AP
- TCP STA -> AP traffic (iperf)
