Subject: wl12xx: sleep instead of wakeup after tx work

commit d05c806 ("wl12xx: rearrange some ELP wake_up/sleep calls")
introduced a bug in which wl1271_ps_elp_wakeup() was called instead
of wl1271_ps_elp_sleep() after completing the tx work.

Subject: wl12xx: avoid premature elp entrance

The elp_work is being enqueued on wl1271_ps_elp_sleep, but doesn't get
cancelled on wl1271_ps_elp_wakeup. This might cause immediate entrance
to elp when the wl->mutex is being released, rather than using the delayed
enqueueing optimization.

Cancel elp_work on wakeup request, and add a new WL1271_FLAG_ELP_REQUESTED
flag to further synchronize the elp actions.

Subject: wl12xx: avoid redundant join on interface reconfiguration

ieee80211_reconfig() sets most of the "changed" flags regardless
of the actual change (e.g. BSS_CHANGED_ASSOC will be set even if
the interface is still not associated). in this case the driver
will issue some unneeded commands.

Since the driver relies solely on the BSS_CHANGED_ASSOC flag,
without checking if there was an actual change, it will end up
issuing unjoin() and dummy_join() commands, although it was
never associated and should just remain idle.

Avoid it by checking the actual state change, in addition to the
"changed" flag.

(there seem to be more redundant configuration commands being
issued, but they shouldn't harm)

When working in ibss mode, we don't configure rate policy per station

1mb/s rate is being used.

Instead, configure the firmware to use the whole 11b rates by default.

Subject: wl12xx: Modify memory configuration for 128x/AP

The 128x/AP firmware does not yet support dynamic memory. Temporarily,
the memory configuration for the 127x was used both for 127x/AP as well
as 128x/AP. Since the two chips don't have the same number of memory
blocks, TP was significantly degraded.

This hasn't been fine tuned yet, but using the base 128x numbers
(without dynamic memory) seems to yield much better results (around 30%
more). Additional fine tuning will be required in the future.

Subject: wl12xx: Restart TX when TX descriptors are available

The driver stops sending TX packets when either there aren't enough
memory blocks, or it runs out of TX descriptors. The driver continues to
send packets to the FW only when more memory blocks are available.

The FW might free TX descriptors without freeing the corresponding
memory blocks, especially when dynamic memory is enabled. In cases where
memory blocks are not freed at all, the driver will keep waiting for
more memory blocks indefinitely.

Fix this by clearing the WL1271_FLAG_FW_TX_BUSY flag when there are
available TX descriptors.

Subject: wl12xx: Enable dynamic memory for 127x

The FW can dynamically manage its internal TX & RX memory pools, moving
blocks from one pool to another when necessary. This can significantly
improve performance. Currently this feature is enabled only for 128x.

Enable dynamic memory for 127x as well. Other parameters in the memory
configuration structure may need to be fine tuned, as the optimal values
for these may change once dynamic memory is enabled.

Subject: wl12xx: use wiphy values for setting rts, frag thresholds on init

Use the wiphy RTS and fragmentation thresholds for initializing the FW
when possible. This mitigates a bug where previously set values are
forgotten after interface down/up.

Add checks before settings these values to ensure they are valid. Use
default values when invalid thresholds are configured.

Update the default RTS threshold to the maximum value given by the
specification.

Subject: wl12xx: schedule recovery on command timeout

We use a long timeout (2 seconds) when sending commands to the FW.
When a command times out, it means the FW is stuck, and we should
commence recovery.

This should make recovery times shorter as we'll recover on the first
timeout indication.

Subject: wl12xx: AP-mode - overhaul rate policy configuration

Use the minimal rate configured in the basic rates set as the AP
broadcast and multicast rate. The minimal rate is used to ensure weak
links can still communicate.

When the basic rates contains at least one OFDM rate, configure all
unicast TX rates to OFDM only.

Unify rate configuration on initialization and on change notification
into a single function.

Subject: wl12xx: fix race condition during recovery in AP mode

When operating as AP, the TX queues are not stopped when we start
recovery. mac80211 is notified only after the fact. When there is
pending TX, it will be queued even after the FW is down. This leads to
situations where the TX queues are stopped (because of the TX-watermark
mechanism), and are never woken up when we return from recovery.

Fix this by explicitly stopping the TX queues when before initiating
recovery.

Subject: wl12xx: export driver state to debugfs

By reading the "driver_state" debugfs value we get all the important
state information from the wl12xx driver. This helps testing and
debugging, particularly in situations where the driver seems "stuck".

Subject: Bluetooth: Add l2cap_add_psm() and l2cap_add_scid()

The intention is to get rid of the l2cap_sk_list usage inside
l2cap_core.c. l2cap_sk_list will soon be replaced by a list that does not
depend on socket usage.

When the user doesn't specify a psm we have the choose one for the
channel. Now we do this inside l2cap_add_psm().

A new list was added to replace the socket based one. This new list
doesn't depent on sock and then fits better inside l2cap_core.c code.

It also rename l2cap_chan_alloc() to l2cap_chan_create() and
l2cap_chan_free() to l2cap_chan_destroy)

Subject: ath9k: Fix drain txq failure in flush

While draining the txq in flush, the buffers can be
added into the tx queue by tx_tasklet which leads to
unneccesary chip reset.

This issue was originially found with AR9382 and
running heavy uplink udp traffic with higher bandwidth
and doing frequent bgscan.

Subject: mac80211: use wake_queue to restart trasmit

netif_tx_start_all_queues is used to allow the upper layer
to transmit frames but it does not restart transmission.
To restart the trasmission use netif_tx_wake_all_queues.
Not doing so, sometimes stalls the transmission and the
application has to be restarted to proceed further.

This issue was originally found while sending udp traffic
in higer bandwidth in open environment without bgscan.

Subject: libertas: remove tx_timeout handler

As described at http://marc.info/?l=linux-netdev&m=130428493104730&w=2
libertas frequently generates spurious tx timeouts, because the tx
queue is brought down for extended periods during scanning. The net
layer takes a look and incorrectly assumes the queue has been down for
several seconds, and generates a tx_timeout.

One way to fix this is to bump the trans_start counter while scanning
so that the network layer knows that the device is still alive, but
I think the tx_timeout handler is implemented wrongly here and not of
any real use, so I vote to remove it.

As explained at http://marc.info/?l=linux-wireless&m=130430311115755&w=2
the watchdog is primarily meant to deal with lockup on the hardware TX
path (detected by the tx queue being stopped for an extended period of
time), but this is unlikely to happen with libertas. In this case, the tx
queue is stopped only while waiting for lbs_thread to send the queued frame
to the driver, and lbs_thread wakes up the queue immediately after, even
if the frame could not be sent correctly.

So, the only hardware-related possibility that this catches is if
hw_host_to_card hangs - this is something I have never seen. And if it
were to happen, nothing done by lbs_tx_timeout would actually wake up
lbs_thread any quicker than otherwise.

Removing this oddly-behaving spuriously-firing tx_timeout handler should
fix an occasional kernel crash during resume
(http://dev.laptop.org/ticket/10748)

The queue mapping of internal mgmt packets is set to VO. Set the TID
value to match the queue mapping. Otherwise drivers that only look at
the TID might get confused.

Subject: mac80211: Postpond ps timer if tx is stopped by others

Whenever the driver's queue depth reaches the max, the queues are
stopped by the driver till the driver can accept the frames.
At the mean time dynamic_ps_timer can be expired due to not
receiving packet from upper layer which could restart the transmission
at the end of ps work. Due to the mismatch with driver state,
mac80211 is unneccesarity buffering all the frames till the driver
wakes up the queue.

Check whether there is no transmit or the tx queues were stopped by some
reasons. If any of the queue was stopped, the postpond ps timer and
do not restart netif_tx.

Subject: rtlwifi: rtl8192se: Modify Kconfig and Makefile routines for new
 driver

Modify rtlwifi routines for rtl8192se and set up Kconfig
and Makefile for new driver.

This patch also disables ASPM for the RTL8192SE to prevent some strange
crashes on LF's system.

From 57f16b5da03784d1660133fbec7281ea5735da69 Mon Sep 17 00:00:00 2001
From: Amitkumar Karwar <akarwar@marvell.com>

Subject: mwifiex: fix simultaneous assoc and scan issue

When scan and assoc (infra/ibss) commands are simultaneously
given in two terminals, association response is erroneously
served while serving the scan response.

mwifiex_cfg80211_results() is the common routine for sending
ioctl (scan, assoc etc.) results to cfg80211 stack. In above
scenario even if the common routine is called for scan ioctl
context, it also tries to send information about assoc ioctl to
cfg80211 because "priv->assoc_request/priv->ibss_join_request"
flag is on at that time.

Fix the issue by updating request variable after assoc handling
and modifying the variable check in mwifiex_cfg80211_results.

Subject: nl80211: Fix set_key regression with some drivers

Commit dbd2fd656f2060abfd3a16257f8b51ec60f6d2ed added a mechanism for
user space to indicate whether a default key is being configured for
only unicast or only multicast frames instead of all frames. This
commit added a driver capability flag for indicating whether separate
default keys are supported and validation of the set_key command based
on that capability.

However, this single capability flag is not enough to cover possible
difference based on mode (AP/IBSS/STA) and the way this change was
introduced resulted in a regression with drivers that do not indicate
the new capability (i.e.., more or less any non-mac80211 driver using
cfg80211) when using a recent wpa_supplicant snapshot.

Fix the regression by removing the new check which is not strictly
speaking needed. The new separate default key functionality is needed
only for RSN IBSS which has a separate capability indication.

The only user of WIPHY_FLAG_SUPPORTS_SEPARATE_DEFAULT_KEYS was removed
and consequently, this flag can be removed, too. In addition, a single
capability flag was not enough to indicate this capability clearly since
the device behavior may be different based on which operating mode is
being used.

Subject: carl9170: fix allmulticast mode

Currently, the driver only disable multicast filtering when the
FIF_ALLMULTI driver flag has been just set (ie,
if changed_flags& FIF_ALLMULTI and *new_flags& FIF_ALLMULTI) or else
it will reenable multicast filtering.

But next time, this condition will be false and multicast filtering
will be reenabled, even through FIF_ALLMULTI is still set.

This mean that allmulticast only works for less than two minutes in
ad-hoc mode.  This patch fixes that to disable multicast filtering
as long as FIF_ALLMULTI is set.

for configuring WoWLAN triggers, and getting
the configuration out again. Changes from the
original patchset are too numerous to list,

the suspend() callback is passed NULL for the
trigger configuration if userspace has not
configured WoWLAN at all.

Subject: mac80211: add basic support for WoWLAN

This adds basic support for the new WoWLAN
configuration in mac80211. The behaviour is
completely offloaded to the driver though,
with two new callbacks (suspend/resume).

Options for the driver include a complete
reconfiguration after wakeup, and exposing
all the triggers it wants to support.

Subject: ath9k_hw: do noise floor calibration only on required chains

At present the noise floor calibration is processed in supported
control and extension chains rather than required chains.
Unnccesarily doing nfcal in all supported chains leads to
invalid nf readings on extn chains and these invalid values
got updated into history buffer. While loading those values
from history buffer is moving the chip to deaf state.

This issue was observed in AR9002/AR9003 chips while doing
associate/dissociate in HT40 mode and interface up/down
in iterative manner. After some iterations, the chip was moved
to deaf state. Somehow the pci devices are recovered by poll work
after chip reset. Raading the nf values in all supported extension chains
when the hw is not yet configured in HT40 mode results invalid values.

Subject: rt2x00: Fix transfer speed regression for USB hardware

Patch:
  rt2x00: Make rt2x00_queue_entry_for_each more flexible
  commit: 10e11568ca8b8a15f7478f6a4ceebabcbdba1018

introduced a severe regression on the throughput
for USB hardware. It turns out that the exiting of
the rt2x00queue_for_each_entry() was done too early.

The exact cause for this regression is unknown,
but by disabling the premature exiting of the loop
seems to resolve the issue.

Subject: ath9k_hw: fix power for the HT40 duplicate frames

With AR9003 at about ~ 10 feet from an AP that uses RTS / CTS you
will be able to associate but not not get data through given that
the power for the rates used was set too low. This increases the
power and permits data connectivity at longer distances from
access points when connected with HT40. Without this you will not
get any data through when associated to APs configured in HT40
at about more than 10 feet away.

Since firmware is capable of generating IV's for all crypto
suits (TKIP, CCMP and WEP), do not ask mac80211 to generate
IV when HW crypto is being used. Instead only reserve
appropriate space in tx skb's in the driver, so that the
firmware can write IV's values.

Subject: iwlwifi: support the svtool messages interactions through nl80211
 test mode

This patch adds the feature to support the test mode operation through
the generic netlink channel NL80211_CMD_TESTMODE between intel
wireless device iwlwifi and the user space application svtool.

The main purpose is to create a transportation layer between the iwlwifi
device and the user space application so that the interaction between the
user space application svtool and the iwlwifi device in the kernel space is
in a way of generic netlink messaging.

The detail specific functions are:

1. The function iwl_testmode_cmd() is added to digest the svtool test command
   from the user space application. The svtool test commands are categorized  to
   three types : commands to be processed by the device ucode, commands to access
   the registers, and commands to be processed at the driver level(such as reload
   the ucode). iwl_testmode_cmd() dispatches the commands the corresponding handlers
   and reply to user space regarding the command execution status. Extra data is
   returned to the user space application if there's any.

2. The function iwl_testmode_ucode_rx_pkt() is added to multicast all the spontaneous
   messages from the iwlwifi device to the user space. Regardless the message types,
   whenever there is a valid spontaneous message received by the iwlwifi ISR,
   iwl_testmode_ucode_rx_pkt() is invoked to multicast the message content to user
   space. The message content is not attacked and the message parsing is left to
   the user space application.

Implementation guidelines:

1. The generic netlink messaging for iwliwif test mode is through  NL80211_CMD_TESTMODE
   channel, therefore, the codes need to follow the regulations set by cfg80211.ko
   to get the actual device instance ieee80211_ops via cfg80211.ko, so that the iwlwifi
   device is indicated with ieee80211_ops and can be actually accessed.

   Therefore, a callback iwl_testmode_cmd() is added to the structure
   iwlagn_hw_ops in iwl-agn.c.

2. It intends to utilize those low level device access APIs from iwlwifi device driver
   (ie. iwlagn.ko) rather than creating it's own set of device access functions.
   For example, iwl_send_cmd(), iwl_read32(), iwl_write8(), and iwl_write32() are reused.

3. The main functions are maintained in new files instead of spreading all over the
   existing iwlwifi driver files.

   The new files added are :

   drivers/net/wireless/iwlwifi/iwl-sv-open.c
        - to handle the user space test mode application command
          and reply the respective command status to the user space application.
        - to multicast the spontaneous messages from device to user space.

   drivers/net/wireless/iwlwifi/iwl-testmode.h
        - the commonly referenced definitions for the TLVs used in
          the generic netlink messages

code, all to avoid a single allocation. Remove it
and consolidate the beacon sending code.

Subject: iwlagn: check DMA mapping errors

DMA mappings can fail, but the current code
doesn't check for that. Add checking, which
requires some restructuring for proper error
paths.

Subject: ath9k: avoid enabling interrupts while processing rx

The assumsion is that while processing ath9k tasklet,
interrupts were already disabled and it will be enabled
at the completion of ath9k tasklet. But whenever TSFOOR is raised,
the driver configures the beacon timers after having received a
beacon frame from the AP which inturn enables the interrupts.

Subject: iwlagn: fix iwl_is_any_associated

The function iwl_is_any_associated() was intended
to check both contexts, but due to an oversight
it only checks the BSS context. This leads to a
problem with scanning since the passive dwell
time isn't restricted appropriately and a scan
that includes passive channels will never finish
if only the PAN context is associated since the
default dwell time of 120ms won't fit into the
normal 100 TU DTIM interval.

Fix the function by using for_each_context() and
also reorganise the other functions a bit to take
advantage of each other making the code easier to
read.

Subject: rtlwifi: Move 2 large arrays off stack

In driver rtlwifi, efuse_read() places two relatively large arrays on the
stack - a 1D u8 array of size 128, and a 2D array of u16 with 128 * 4 elements.
With driver rtl8192de, the sizes will be 256 and 256 * 4 respectively. As that
will make the 2D array be 2048 bytes, I have changed the code to use kmalloc to
allocate the space.

Subject: mac80211: don't drop frames where skb->len < 24 in
 ieee80211_scan_rx()

This seems to be a leftover from the old days, when we didn't support
any frames that didn't contain the full ieee802.11 header.  This is
not the case anymore.  It does not cause problems now, because they
are only dropped during scan.  But when scheduled scans get merged,
this would become a problem because we would drop all small frames
while scheduled scan is running.

To fix this, return RX_CONTINUE instead of RX_DROP_MONITOR.

Subject: bcma: add Broadcom specific AMBA bus driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Broadcom has released cards based on a new AMBA-based bus type. From a
programming point of view, this new bus type differs from AMBA and does
not use AMBA common registers. It also differs enough from SSB. We
decided that a new bus driver is needed to keep the code clean.

In its current form, the driver detects devices present on the bus and
registers them in the system. It allows registering BCMA drivers for
specified bus devices and provides them basic operations. The bus driver
itself includes two important bus managing drivers: ChipCommon core
driver and PCI(c) core driver. They are early used to allow correct
initialization.

Currently code is limited to supporting buses on PCI(e) devices, however
the driver is designed to be used also on other hosts. The host
abstraction layer is implemented and already used for PCI(e).

Support for PCI(e) hosts is working and seems to be stable (access to
80211 core was tested successfully on a few devices). We can still
optimize it by using some fixed windows, but this can be done later
without affecting any external code. Windows are just ranges in MMIO
used for accessing cores on the bus.

+Broadcom introduced new bus as replacement for older SSB. It is based on AMBA,
+however from programming point of view there is nothing AMBA specific we use.
+
+Standard AMBA drivers are platform specific, have hardcoded addresses and use
+AMBA standard fields like CID and PID.
+
+In case of Broadcom's cards every device consists of:
+1) Broadcom specific AMBA device. It is put on AMBA bus, but can not be treated
+   as standard AMBA device. Reading it's CID or PID can cause machine lockup.
+2) AMBA standard devices called ports or wrappers. They have CIDs (AMBA_CID)
+   and PIDs (0x103BB369), but we do not use that info for anything. One of that
+   devices is used for managing Broadcom specific core.
+
+Addresses of AMBA devices are not hardcoded in driver and have to be read from
+EPROM.
+
+In this situation we decided to introduce separated bus. It can contain up to
+16 devices identified by Broadcom specific fields: manufacturer, id, revision
+and class.

Subject: mwifiex: remove unnecessary struct mwifiex_opt_sleep_confirm_buffer

The structure definition is
struct mwifiex_opt_sleep_confirm_buffer {
       u8 hdr[4];
       struct mwifiex_opt_sleep_confirm ps_cfm_sleep;
} __packed;

For sleep_confirm command we already reserve 4 bytes (using skb_reserve())
for an interface header. It will be filled later by interface specific code.
We don't need "hdr[4]" element in above structure. So we can use
"struct mwifiex_opt_sleep_confirm" directly instead of
"struct mwifiex_opt_sleep_confirm_buffer".

Subject: ssb: update list of devices supporting multiple 80211 cores
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some of the BCM43xx chips contain cores that are attached to the SSB, but are
inactive as they do not connect to the external environment. These must not be
registered. Several of these types are handled in driver ssb; however, the
specific case of an inactive 802.11 cores is now treated in b43 and b43legacy.
Although the current setup works, this minor change will place all such
workarounds in ssb, and simplify the code in drivers b43 and b43legacy.

From: Joe Perches <joe@perches.com>
Date: Mon, 2 May 2011 16:49:15 -0700
Subject: libertas: Use netdev_<level> or dev_<level> where possible

Using the more descriptive logging styles gives a bit
more information about the device being operated on.

Makes the object trivially smaller too.

Subject: Bluetooth: Double check sec req for pre 2.1 device

In case of pre v2.1 devices authentication request will return
success immediately if the link key already exists without any
authentication process.

That means, it's not possible to re-authenticate the link if you
already have combination key and for instance want to re-authenticate
to get the high security (use 16 digit pin).

Therefore, it's necessary to check security requirements on auth
complete event to prevent not enough secure connection.

Subject: nl80211: Introduce NL80211_MESH_SETUP_USERSPACE_AMPE

Introduce a new configuration option to support AMPE from userspace.

Prior to this series we only supported authentication in userspace: an
authentication daemon would authenticate peer candidates in userspace
and hand them over to the kernel.  From that point the mesh stack would
take over and establish a peer link (Mesh Peering Management).

These patches introduce support for Authenticated Mesh Peering Exchange
in userspace.  The userspace daemon implements the AMPE protocol and on
successfull completion create mesh peers and install encryption keys.

Subject: open80211s: Stop using zero for address 3 in mesh plink mgmt frames

Previous versions of 11s draft used the all zeroes address.  Current
draft uses the same address as address 2.

Also, use the ANA-approved action category code for peer establishment frames.

Note: This breaks compatibility with previous mesh protocol instances.

Subject: cfg80211: Use capability info to detect mesh beacons.

Mesh beacons no longer use all-zeroes BSSID.  Beacon frames for MBSS,
infrastructure BSS, or IBSS are differentiated by the Capability
Information field in the Beacon frame.  A mesh STA sets the ESS and IBSS
subfields to 0 in transmitted Beacon or Probe Response management
frames.

Subject: mac80211: Check size of a new mesh path table for changes since
 allocation.

Not sure if I'm chasing a ghost here, seems like the
mesh_path->size_order needs to be inside an RCU-read section to prevent
that value from changing between table allocation and copying.  We have
observed crashes that might be caused by this.

Subject: mac80211: Fix locking bug on mesh path table access

The mesh and mpp path tables are accessed from softirq and workqueue
context so non-irq locking cannot be used.  Or at least that's what
PROVE_RCU seems to tell us here:

The functions drv_add_interface() and drv_remove_interface() print out
the same values in the traces.  Combine the traces of these two

Also add a new class for functions drv_set_frag_threshold() and

Subject: cfg80211/nl80211: add support for scheduled scans

Implement new functionality for scheduled scan offload.  With this feature we
can scan automatically at certain intervals.

The idea is that the hardware can perform scan automatically and filter on
desired results without waking up the host unnecessarily.

Add NL80211_CMD_START_SCHED_SCAN and NL80211_CMD_STOP_SCHED_SCAN
commands to the nl80211 interface.  When results are available they are
reported by NL80211_CMD_SCHED_SCAN_RESULTS events.  The userspace is
informed when the scheduled scan has stopped with a
NL80211_CMD_SCHED_SCAN_STOPPED event, which can be triggered either by
the driver or by a call to NL80211_CMD_STOP_SCHED_SCAN.

Subject: mac80211: add support for HW scheduled scan

Implement support for HW scheduled scan.  The mac80211 code doesn't perform
scheduled scans itself, but calls the driver to start and stop scheduled
scans.

This patch also creates a trace event class to be used by drv_hw_scan
and the new drv_sched_scan_start and drv_sched_stop functions, in
order to avoid duplicate code.

Subject: cfg80211/nl80211: add interval attribute for scheduled scans

Introduce NL80211_ATTR_SCHED_SCAN_INTERVAL as a required attribute for
NL80211_CMD_START_SCHED_SCAN.  This value informs the driver at which
intervals the scheduled scan cycles should be executed.

Subject: cfg80211: restrict AP beacon intervals

Multiple virtual AP interfaces can currently try
to use different beacon intervals, but that just
leads to problems since it won't actually be done
that way by drivers. Return an error in this case
to make sure it won't be done wrong.

Also, ignore attempts to change the DTIM period
or beacon interval during the lifetime of the BSS.

Subject: mac80211: fix contention time computation in minstrel, minstrel_ht

When transmitting a frame, the transmitter waits a random number of
slots between 0 and cw. Thus, the contention time is (cw / 2) * t_slot
which we can represent instead as (cw * t_slot) >> 1. Also fix a few
other accounting bugs around contention time, and add comments.

band. Users of these cards then would see 2.4 GHz channels
but you would never get any scan results from these channels
given that the radio is not present.

The function
- increments dropped rx_packet count if status code
  passed to it is "-1".
- frees SKB buffer.

But currently the function is being called with "0" status code.
This patch replaces above function by dev_kfree_skb_any() call.

Subject: mac80211: remove pointless mesh path timer RCU code

The code here to RCU-dereference a pointer that's
on the stack is totally pointless, RCU isn't magic
(like say Java's weak references are), so the code
can't work like whoever wrote it thought it might.

Remove it so readers don't get confused. Note that
it seems that a bug is there anyway: I don't see
any code that cancels the timer when a mesh path
struct is destroyed.

Subject: mac80211: make key locking clearer

The code in ieee80211_del_key() doesn't acquire the
key_mtx properly when it dereferences the keys. It
turns out that isn't actually necessary since the
key_mtx itself seems to be redundant since all key
manipulations are done under the RTNL, but as long
as we have the key_mtx we should use it the right
way too.

Subject: mac80211: fix another key non-race

The code here is only not racy because all the
places that assign the pointers it uses are
holding the sta_mtx as well as the key_mtx and
so can't race against this because this code
holds the sta_mtx. But that's not intuitive,
so fix it to hold the key_mtx.

Subject: cfg80211/mac80211: avoid bounce back mac->cfg->mac on
 sched_scan_stopped

When sched_scan_stopped was called by the driver, mac80211 calls
cfg80211, which in turn was calling mac80211 back with a flag
"driver_initiated".  This flag was used so that mac80211 would do the
necessary cleanup but would not call the driver.  This was enough to
prevent the bounce back between the driver and mac80211, but not
between mac80211 and cfg80211.

To fix this, we now do the cleanup in mac80211 before calling
cfg80211.  To help with locking issues, the workqueue was moved from
cfg80211 to mac80211.

Subject: mac80211: mesh: move some code to make it static

There's no need to have table functions in one
file and all users in another, move the functions
to the right file and make them static. Also move
a static variable to the beginning of the file to
make it easier to find.

Subject: wl12xx: simplify wl1271_ssid_set()

Simplify wl1271_ssid_set by re-using cfg80211_find_ie instead of
reimplementing it.

Additionally, add a length check to prevent a potential buffer overflow.

Subject: wl12xx: Don't filter beacons that include changed HT IEs

This patch adds a beacon filter rule to pass up the beacons that
contain changed HT information elements.  These beacons need to be
passed to mac80211 so that it can act on such changes.

Set the spectrum management bit in the hw flags so that mac80211 will

(which in practice means that we support 802.11h spectrum management).

Subject: wl12xx_sdio: set MMC_PM_KEEP_POWER flag on suspend

if a wow trigger was configured, set the MMC_PM_KEEP_POWER flag
on suspend, so our power will be kept while the system is suspended.

We needed to set this flag on each suspend attempt (when we want
to keep power)

Subject: wl12xx: prevent scheduling while suspending (WoW enabled)

When WoW is enabled, the interface will stay up and the chip will
be powered on, so we have to flush/cancel any remaining work, and
prevent the irq handler from scheduling a new work until the system
is resumed.

Add 2 new flags:
* WL1271_FLAG_SUSPENDED - the system is (about to be) suspended.
* WL1271_FLAG_PENDING_WORK - there is a pending irq work which
   should be scheduled when the system is being resumed.

In order to wake-up the system while getting an irq, we initialize
the device as wakeup device, and calling pm_wakeup_event() upon
getting the interrupt (while the system is about to be suspended)

Subject: cfg80211: advertise possible interface combinations

Add the ability to advertise interface combinations in nl80211.
This allows the driver to indicate what the combinations are
that it supports. "Combinations" of just a single interface are
implicit, as previously. Note that cfg80211 will enforce that
the restrictions are met, but not for all drivers yet (once all
drivers are updated, we can remove the flag and enforce for all).

When no combinations are actually supported, an empty list will
be exported so that userspace can know if the kernel exported
this info or not (although it isn't clear to me what tools using
the info should do if the kernel didn't export it).

Since some interface types are purely virtual/software and don't
fit the restrictions, those are exposed in a new list of pure SW
types, not subject to restrictions. This mainly exists to handle
AP-VLAN and monitor interfaces in mac80211.

 /**
+ * DOC: Virtual interface / concurrency capabilities
+ *
+ * Some devices are able to operate with virtual MACs, they can have
+ * more than one virtual interface. The capability handling for this
+ * is a bit complex though, as there may be a number of restrictions
+ * on the types of concurrency that are supported.
+ *
+ * To start with, each device supports the interface types listed in
+ * the %NL80211_ATTR_SUPPORTED_IFTYPES attribute, but by listing the
+ * types there no concurrency is implied.
+ *
+ * Once concurrency is desired, more attributes must be observed:
+ * To start with, since some interface types are purely managed in
+ * software, like the AP-VLAN type in mac80211 for example, there's
+ * an additional list of these, they can be added at any time and
+ * are only restricted by some semantic restrictions (e.g. AP-VLAN
+ * cannot be added without a corresponding AP interface). This list
+ * is exported in the %NL80211_ATTR_SOFTWARE_IFTYPES attribute.
+ *
+ * Further, the list of supported combinations is exported. This is
+ * in the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute. Basically,
+ * it exports a list of "groups", and at any point in time the
+ * interfaces that are currently active must fall into any one of
+ * the advertised groups. Within each group, there are restrictions
+ * on the number of interfaces of different types that are supported
+ * and also the number of different channels, along with potentially
+ * some other restrictions. See &enum nl80211_if_combination_attrs.
+ *
+ * All together, these attributes define the concurrency of virtual
+ * interfaces that a given device supports.

Subject: mac80211: fix TX a-MPDU locking

During my quest to make mac80211 not have any RCU
warnings from sparse, I came across the a-MPDU code
again and it wasn't quite clear why it isn't racy.
So instead of assigning the tid_tx array with just
the spinlock held in ieee80211_start_tx_ba_session
use a separate temporary array protected only by
the spinlock and protect all assignments to the
"live" array by both the spinlock and the mutex so
that other code is easily verified to be correct.

Due to pointer assignment atomicity I don't think
this is a real issue, but I'm not sure, especially
on Alpha the current code might be problematic.

Subject: mac80211: sparse RCU annotations

This adds sparse RCU annotations to most of
mac80211, only the mesh code remains to be
done.

Due the the previous patches, the annotations
are pretty simple. The only thing that this
actually changes is removing the RCU usage of
key->sta in debugfs since this pointer isn't
actually an RCU-managed pointer (it only has
a single assignment done before the key even
goes live). As that is otherwise harmless, I
decided to make it part of this patch.

Subject: net/rfkill/core.c: Avoid leaving freed data in a list

The list_for_each_entry loop can fail, in which case the list element is
not removed from the list rfkill_fds.  Since this list is not accessed by
the loop, the addition of &data->list into the list is just moved after the
loop.

The sematic match that finds this problem is as follows:

Subject: ath9k_hw: define antenna diversity group

AR9285 belongs to diversity group 0 and AR9485 belongs to diversity
group 2. Based on the diversity group we configure certain antenna
diversity paramaters such as lna1_lna2_delta and fast diversity
bias values. For AR9485 we have some gain table parameter which
selects the gain table 0/1 for main and alternate antenna

Subject: ath9k: Implement an API to swap main/ALT LNA's

for the diversity group 2(AR9485) we swap the LNA's of main/ALT antenna
based on alternate antenna's rssi average in comparision with main
antenna's rssi, while for AR9285(antenna diversity group 0)we still
follow the older method of looking at the packet count in alternate
antenna

Subject: ath9k: make sure main_rssi is positive

some times the rssi control descriptor for the main antenna may be
negative like that of alternate antenna, hence before  incrementing
packet counts/rssi of main/alternate antenna make sure both main_rssi
and alt_rssi are positive only. this avoids wrong selection of antenna
due to diversity

we are not doing anything by tracking the number of pending frames.
bail out when we first find a pending frame in any one of the 10 queues.

Subject: nl80211: Move peer link state definition to nl80211

These definitions need to be exposed now that we can set the peer link
states via NL80211_ATTR_STA_PLINK_STATE.  They were already being
(opaquely) reported by NL80211_STA_INFO_PLINK_STATE.

Subject: cfg80211: make stripping of 802.11 header optional from AMSDU

Currently the devices that have already stripped IEEE 802.11
header from the AMSDU SKB can not use ieee80211_amsdu_to_8023s
routine. This patch enhances ieee80211_amsdu_to_8023s() API by
changing mandatory removing of IEEE 802.11 header from AMSDU
to optional.

Subject: mwifiex: use ieee80211_amsdu_to_8023s routine

mwifiex was using its own implementation of converting 802.11n
AMSDU to 802.3s.  This patch removes mwifiex specific
implementation and uses existing ieee80211_amsdu_to_8023s
routine.
