Subject: ath6kl: Use cfg80211_roamed_bss() to report roaming event

This is to avoid the scenario where the bss entry of the AP got
expired when reporting roaming event to current AP. As the bss
entry for the current bss is available in driver, pass this bss
to cfg80211. This fixes WARNING: at net/wireless/sme.c:586.

This patch depends on the following patch in cfg80211
"cfg80211: Fix race in bss timeout".

Subject: ath6kl: Fix connect command to clear previously used IEs

Empty IE buffer means that the new association is not supposed to
include extra IEs. Make sure any previously configured (Re)Association
Request frame IEs get cleared in such a case. This is based on a patch
from Shuibing.

Subject: ath6kl: Avoid taking struct as argument in ath6kl_wmi_set_ip_cmd

In this way, caller is free to pass only the value of IP addr
to configure.

In addition to this,
  * 'ips' variable data type in struct wmi_set_ip_cmd is changed
     from __le32 to __be32 in order to match network byte order.
  *  ipv4_is_multicast() is used to validate multicast ip addr.
  *  New argument if_idx is added to supply correct vif index
     to ath6kl_wmi_cmd_send().

This will be used in the next patch.

Subject: ath6kl: Send own IP addr to the firmware during WOW suspend

Firmware ARP module requires own IP addr in order to respond
to the outside world when the target is in WOW suspend state.

At present, firmware ARP module has capability to hold 2 IP addr.
So, WOW mode will be disabled if the total IP addr configured in
net_dev for our device is greater than firmware limit (MAX_IP_ADDRS)
which is 2 at this moment.

Subject: ath6kl: handle firmware names more dynamically

Currently ath6kl has just hardcoded paths to each firmware file. Change
this more dynamic by separating the the directory and file name from each
other. That way it's easier to dynamically create full paths to firmware and
code looks better. And now it's possible to remove a function needed by
devicetree code.

While at it add a structure inside struct ath6kl_hw to contain all
firmware names. I deliberately omitted board file support as
those will be handled later.

This is needed for firmware API 3.

Subject: ath6kl: add support for FW API 3

As firmware starting from 3.2.0.12 has some API changes and doesn't work
with older versions of ath6kl we need to bump up the API version. This
way we don't break anything.

Also store which version of API is used and print that during boot:

ath6kl: ar6003 hw 2.1.1 sdio fw 3.2.0.13 api 3

Subject: ath6kl: Fix panic when setting a channel

cfg80211 could pass a NULL net_device to the driver via the
set_channel() callback, when it receives a request to set the
device's channel. Not handling this case properly results in this panic:

Subject: ath6kl: Add del_station cfg80211_ops

hostapd/wpa_supplicant AP mode uses this operation to flush the station
entries. Implement this in ath6kl to avoid unnecessary warnings from
NL80211_CMD_DEL_STATION failing.

Subject: ath6kl: Advertise TX/RX support for frames in AP mode

This is needed to fix current hostapd/wpa_supplicant AP operations for
frame registration. P2P GO mode already advertised these, but AP mode
was forgotten and could not be used after the hostapd/wpa_supplicant
frame registration changes.

Subject: ath6kl: Support for TCP checksum offload to firmware

The change enables offloading TCP checksum calculation to firmware.
There are still some issues with the checksum offload so better to
disable it by default until the issues are resolved.

To enable TCP checksum offload for tx and rx paths, use
the ethtool as follows:
ethtool -K <interface> tx on
ethtool -K <interface> rx on

To disable TCP checksum offload, for tx and rx paths, use
the ethtool as follows:
ethtool -K <interface> tx off
ethtool -K <interface> rx off

Subject: ath6kl: send TCMD response through testmode events

ath6kl no longer knows what it is transmitting through
cfg80211_testmode, and simply passes opaque buffers between userspace
and the firmware. Leave the CONT_RX enum for backwards compatibility.

kvalo: change ATH6KL_TM_CMD_RX_REPORT to return -EOPNOTSUPP

Subject: ath6kl: Implement ndo_set_rx_mode()

There are maximum of seven multicast filter are supported
by hw. When the requested number of filters exceeds the
maximum supported one, multicast filtering is completely
disabled, the requested filters will be configured in
firmware and the only multicast frames that host is interested
in will be passed to host for further processing otherwise.

Subject: ath6kl: Remove deadcode in main.c

In ath6kl_reset_device(), since control can never reach switch..case
when the target_type is neither TARGET_TYPE_AR6003 nor TARGET_TYPE_AR6004,
remove the default option of switch statement.

Subject: ath6kl: Change ielen in ath6kl_add_new_sta() from u8 to size_t

Otherwise if (ielen <= ATH6KL_MAX_IE) is dead code. It looks safe to
change the type of ielen from u8 to size_t instead of removing this
if check, this ielen can have the length of more than one ies in future.

Subject: ath6kl: Use a mutex_lock to avoid race in diabling and handling irq

Currently this race is handled but in a messy way an atomic
variable is being checked in a loop which sleeps upto ms
in every iteration. Remove this logic and use a mutex
to make sure irq is not disabled when irq handling is in
progress.

Subject: ath6kl: Fix listen interval handling

This patch addresses a few problems with the commit:

"ath6kl: Implement support for listen interval from userspace"

* The debugfs file required for reading/writing the listen interval
  wasn't created. Fix this.

* The interface index was being hardcoded to zero. Fix this.

* Two separate parameters, "listen_interval_time and listen_interval_beacons"
  were being used. This fails to work as expected because the FW assigns
  higher precedence to "listen_interval_beacons" and "listen_interval_time"
  ends up being never used at all.

  To handle this, fix the host driver to exclusively use listen interval
  based on units of beacon intervals.

To set the listen interval, a user would now do something like this:

echo "10" > /sys/kernel/debug/ieee80211/*/ath6kl/listen_interval

kvalo: fix two checkpatch warnings

Subject: ath6kl: Add support for uAPSD

* A new APSD power save queue is added in the station structure.
* When a station has APSD capability and goes to power save, the frame
  designated to the station will be buffered in APSD queue.
* When the host receives a frame which the firmware marked as trigger,
  host delivers the buffered frame from the APSD power save queue.
  Number of frames to deliver is decided by MAX SP length.
* When a station moves from sleep to awake state, all frames buffered
  in APSD power save queue are sent to the firmware.
* When a station is disconnected, all frames bufferes in APSD power save
  queue are dropped.
* When the host queues the first frame to the APSD queue or removes the
  last frame from the APSD queue, it is indicated to the firmware using
  WMI_AP_APSD_BUFFERED_TRAFFIC_CMD.

kvalo: fix buggy handling of sks queues, made it more obvious
the user priority when wmm is disabled, remove unneed else block and
combined some variable declarations

Subject: ath6kl: Remove useless initialization in ath6kl_read_fwlogs()

ath6kl_read_fwlogs() assigns the value zero to the variable 'ret'
at the time of declaration. Later, return value of ath6kl_diag_read32()
repalces the init value. Hence removing useless zero assignment.

Subject: ath6kl: use netdev_features_t

Commit c8f44affb7 ("net: introduce and use netdev_features_t for
device features sets") added netdev_features_t to ndo_set_features.
Change ath6kl to use the new type.

This fixes a warning:

Subject: ath6kl: fix uninitialized warning in ath6kl_process_uapsdq()

Before I commited patch c1762a3fe ("ath6kl: Add support for uAPSD") I
did a minor change how up variable is initialised in
ath6kl_process_uapsdq(). But I was sloppy and caused this compiler
warning:

txrx.c:88:5: warning: 'up' may be used uninitialized in this function

Revert my change to fix the warning.

Add testmode 2 for 6003 ART. When you insmod ath6kl_sdio.ko testmode=2, ath6kl
will load ART firmware utf.bin and testscript nullTestFlow.bin. These files
should be put in the firmware folder.

Subject: ath6kl: add ATH6KL_CONF_UART_DEBUG

Add ATH6KL_CONF_UART_DEBUG which is set whenever uart_debug module
parameter is enabled. This way we can keep the uart_debug parameter
static when core.c file is introduced.

Subject: ath6kl: create core.c

Currently core functions are spread between various files, group all
the functions into file and rename the functions to follow the style
used elsewhere in the driver. This will make it easier to a separate core
module.

Also fix a bug where wiphy is freed too early.

Subject: ath6kl: get rid of AR_DBG_LVL_CHECK()

We don't need it as debug calls already have a log level and compiler
should be smart enough to optimise away the code when ath6kl debug code
is not enabled. Also it makes it easier to abstract core code to
ath6kl_core.ko.

In ath6kl_dump_registers() I had to change the debug level from ANY to IRQ
as I removed the AR_DBG_LVL_CHECK() check before calling the function.

That way it's possible to not export debug_mask outside the upcoming
ath6kl_core.ko and that makes it easier to ath6kl_core.ko in the
following patch.

Subject: ath6kl: create ath6kl_core.ko

Now ath6kl is ready for splitting core code to ath6kl_core.ko module.
This also makes it possible to link both sdio and usb code to kernel
at the same time, which earlier failed miserably.

From 241b128b6b69ad41fc6f12cba45a3c3e64bce673 Mon Sep 17 00:00:00 2001

Subject: ath6kl: add back beginnings of USB support

John Linville had to revert the part of USB support which was already
in ath6kl due to build problems in commit cb00ec382b ("ath6kl: revert
USB support"). Now that I fixed the build problems properly by adding
ath6kl_core.ko kernel module it's possible to add back the
(incomplete) USB support. This patch is a revert of John's patch and
adds back the USB code which as already in ath6kl, only difference
being minor changes in Makefile and adapting usb.c to new core
function names.

Note that USB support in ath6kl is not complete yet. This code only
makes it possible to boot firmware but as HTC layer does not yet
support USB it's not possible to send any WMI commands nor data
packets to the firmware. That will be added soon.

Subject: ath6kl: Make sure to delete rx aggregation timer in
 aggr_reset_state()

The timer which is used to flush rx aggregation frames needs to
be disabled when resetting the aggregation state. This is found
in code review.

Subject: ath6kl: Fix memory leak when unloading ath6kl_sdio

The patch "ath6kl: create core.c" removes wiphy_free() from
ath6kl_cfg80211_cleanup() and misses to free wiphy in
ath6kl_sdio_remove(). This patch fixes this regression.

Subject: ath6kl: Define a structure for connection specific aggregation
 information

This patch just groups connection specific aggregation information
from struct aggr_info into a new structure (struct aggr_info_conn)
so that, in softAP mode, this can be used when each connected station
is made to have it's own aggregation state.

Subject: ath6kl: Fix bug in using tid given by addba/delba req events

The tid which is given in addba/delba req event is not
just tid but also muxed with the assoc id (MSB 4 bits)
which can be used to determine the corresponding connected
station in softap mode. The actual tid is LSB 4 bits. Using
the tid as it is with rx_tid[] would result in OOB or invalid
memory access in AP mode.

Subject: ath6kl: Fix bug in maintaining aggregation state in AP mode

Currently rx aggregation related states are maintained per
vif, but this will not properly work when operating in AP mode.
Aggregation is completely broken when more than one
11n stations are connected to AP mode vif. Fix this issue
by keeping station specific aggregation state in sta_list.

Subject: iwlwifi: fix uCode event tracing

Fix multiple bugs in event tracing:

1) If you enable uCode tracing with the device down,
   it will still attempt to access the device and
   continuously log "MAC is in deep sleep!" errors.
   Fix this by only starting logging when the device
   is actually alive.

2) Now you can set the flag when the device is down,
   but logging doesn't happen when you bring it up.
   To fix that, start logging when the device comes
   alive. This means we don't log before -- we could
   do that but I don't need it right now.

3) For some reason we read the error instead of the
   event log -- use the right pointer.

4) Optimise SRAM reading of event log header.

5) Fix reading write pointer == capacity, which can
   happen due to racy SRAM access

6) Most importantly: fix an error where we would try
   to read WAY too many events (like 2^32-300) when
   we read the wrap counter before it is updated by
   the uCode -- this does happen in practice and will
   cause the driver to hang the machine.

7) Finally, change the timer to 10ms instead of 100ms
   as 100ms is too slow to capture all data with a
   normal event log and with 100ms the log will wrap
   multiple times before we have a chance to read it.

Subject: iwlwifi: always restrict scan dwell in P2P

Whenever the PAN (P2P) context is active, it
has timers in the uCode that prevent sleep,
so scanning can't be out of channel for more
than the beacon interval programmed into the
device.

Before this patch, a full scan including any
passive channels when P2P was active would
stall forever because it wouldn't find time
to execute the passive requests (for default
beacon intervals of 100 TU.)

Testmode (TCMD and ART) was not enabled when fw-2.bin or fw-3.bin files
were available, fix that by fetching testmode file just after the
board file but before rest of the firmware files are fetched.

I also added testmode field to struct ath6kl and moved the module parameter
to core.c. Now all module parameters are grouped in one place.

Subject: ath6kl: Fix kernel panic during rx aggregation

"ath6kl: Define a structure for connection specific aggregation information"
introduces this. In aggr_conn_init(), vif->aggr_cntxt is assigned to
aggr_conn->aggr_info, but vif->aggr_cntxt is not initialized at this
point, this would end up accessing an invalid pointer in aggregation
receive path. Fix this by passing the correct aggr_info to aggr_conn_init().
The panic trace would look like.

Subject: ath6kl: Re-architect suspend mode handling in ath6kl_sdio_suspend

Using this patch, the user can bypass existing auto
suspend mode selection logic and force ath6kl to enter
into the suspend mode what he/she wants.

If the user doesn't choose any suspend mode while doing
insmod of the driver, auto suspend mode selection logic
will kick in and choose suspend mode based on the host
SDIO controller capability.

Generic module parameter is required to specify suspend
mode including Deep Sleep and WOW while doing insmod.
Renaming existing mod param variable suspend_cutpower
would be sufficient to meet this requirement.

New module parameter suspend_mode can take any one of
the below suspend state,
   1. cut power
   2. deep sleep
   3. wow

Subject: ath6kl: Configure WOW patterns while going to wow_suspend

First preference is given to the user configured WOW patterns.
If the user doesn't configure any patterns (for ex, via iw command),
the default patterns will be configured based on the current mode
(vif->nw_type) while going to WOW suspend.

Summary of changes:

  * ath6kl_wow_ap() is added to configure the below default
    patterns when the system enters into WOW suspend in AP mode.
      + Unicast IP, EAPOL-like and ARP packet pattern
      + ARP packet pattern
      + mDNS/SSDP/LLMNR pattern
      + DHCP broadcast pattern

 * ath6kl_wow_sta() is added to configure the below default
   patterns when the system enters into WOW suspend in STA mode.
      + Unicast packet pattern
      + mDNS/SSDP/LLMNR pattern

  * Move the user provided WOW patterns configuration code
    from ath6kl_wow_suspend() to a separate function called
    ath6kl_wow_usr().

  * Two argument variable's ('filter' and 'mask) data type in
    ath6kl_wmi_add_wow_pattern_cmd() are changed from 'u8 *' to
    'const u8 *'. This is needed to make all pattern and mask
    arrays to be 'static const u8' in the caller function.

  * New conditional check is added to make sure user
    configured pattern count is within the limit (WOW_MAX_FILTERS_PER_LIST).

Subject: ath6kl: Wait for host sleep mode cmd processed event during WOW
 suspend

For every WMI_SET_HOST_SLEEP_MODE_CMDID command (send from the host),
the firmware sends WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID as
an acknowledgement to the host.

In order to being sync with the firmware, the host has to wait for
WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENT event before going to
the suspend state. This patch ensures ath6kl_wow_suspend() waits
until it gets this event after sending set host sleep mode command.

This patch adds,
 * New command WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID in
   WMI event table.
 * New WMI function ath6kl_wmi_host_sleep_mode_cmd_prcd_evt_rx()
   to process the event.
 * New flag HOST_SLEEP_MODE_CMD_PROCESSED in VIF flags to record
   the arrival of the event.

Subject: ath6kl: Return a proper error code when not in connected state

Error code ENOTCONN is more suitable than EINVAL to report
when the driver is not in connected state in ath6kl_wow_suspend().

I found this during code review.

Subject: ath6kl: fix compiler warning in ath6kl_init_hw_params()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both Luis and John reported that they see a compiler warning:

drivers/net/wireless/ath/ath6kl/init.c: In function 'ath6kl_init_hw_params':
drivers/net/wireless/ath/ath6kl/init.c:1377:26: warning: ‘hw’
may be used uninitialized in this function

Oddly enough I have never seen it. But AFAICT the code is correct and
hw is not used uninitalized so add uninitialized_var() to inform that to
the compiler.

Subject: iwlwifi: allocate the transport from the bus layer

Change the way we alloc the transport on the way.
Since the transport is allocated from a bus specific area, we can
give the bus specific parameters (i.e. pci_dev for PCI) to the
transport. This will be useful when the bus layer will be killed.

Subject: iwlwifi: give trans to all the read / write functions

From now on, the transport layer in charge of providing access to the
device. So change all the driver to give a pointer to the transport
to all the low level functions that actually access the device.

Subject: iwlwifi: introduce trans_ops->stop_hw

This handler stops the HW and puts it in low power state.
It will allow to clean up the flows in the upper layers.

Subject: iwlwifi: consolidate the start_device flow

Now there is only one transport function that launch a specific fw:
trans_ops->start_fw. This one replaces trans_ops->start_device and
trans_ops->kick_nic. The code that actually loads the fw to the
device has been moved to the transport specific code.

Subject: iwlwifi: stop_hw replace enable_rfkill_int

This trans_ops->stop_hw leaves the RFKILL interrupt enabled,
we can call that one instead of enable_rfkill_int. By that,
we reduce the numbers of acceesses to the NIC from the upper
layers.

The message was misleading when a queue is deactivated. The fifo
number is irrelevant then, so don't print it.

Subject: mac80211: move managed mode station state modification

Move the station state modification right before insert,
this just makes the current code more readable (you can
tell that it's before insertion looking at a single
screenful of code) right now, but some upcoming changes
will require this.

Subject: mac80211: simplify AP_VLAN handling

Setting keys and updating TKIP keys must use the
BSS sdata (not AP_VLAN), so we translate. Move
the translation into driver-ops wrappers instead
of having it inline in the code to simplify the
normal code flow.

The same can be done for sta_add/remove which
already does the translation in the wrapper.

Subject: mac80211: dont program keys for stations not uploaded

If a station couldn't be uploaded to the driver but
is still kept (only in IBSS mode) we still shouldn't
try to program the keys for it into hardware; fix
this bug by skipping the key upload in this case.

Subject: mac80211: add sta_state callback

(based on Eliad's patch)

Add a callback to notify the low-level driver whenever
the state of a station changes. The driver is only
notified when the station is actually in the mac80211
hash table, not for pre-insert state transitions.

To allow the driver to replace sta_add/remove calls
with this, call extra transitions with the NOTEXIST
state.

This callback can fail, so we need to be careful in
handling it when a station is inserted, particularly
in the IBSS case where we still keep the station entry
around for mac80211 purposes.

Subject: mac80211: implement sta_add/sta_remove in sta_state

Instead of maintaining separate sta_add/sta_remove
callsites, implement it in sta_state when the driver
has no sta_state implementation.

The only behavioural change this should cause is in
secure mesh mode: with this the station entries will
only be created after the stations are set to AUTH.
Given which drivers support mesh, this seems to not
be a problem.

Subject: mac80211: remove dummy STA support

The dummy STA support was added because I didn't
want to change the driver API at the time. Now
that we have state transitions triggering station
add/remove in the driver, we only call add once a
station reaches ASSOCIATED, so we can remove the
dummy station stuff again.

While at it, tighten the RX check and accept only
port control (EAP) frames from the AP station if
it's not associated yet -- in other cases there's
no race.

Subject: cfg80211: stop tracking authenticated state

To track authenticated state seems to have been
a design mistake in cfg80211. It is possible to
have out of band authentication (FT), tracking
multiple authentications caused more problems
than it ever helped, and the implementation in
mac80211 is too complex.

Remove all this complexity, and let userspace
do whatever it wants to, mac80211 can deal with
that just fine. Association is still tracked of
course, but authentication no longer is. Local
auth state changes are thus no longer of value,
so ignore them completely.

This will also help implement SAE -- asking the
driver to do an authentication is now almost
equivalent to sending an authentication frame,
with the exception of shared key authentication
which is still handled completely.

Subject: cfg80211: export cfg80211_ref_bss

This is needed by mac80211 to keep a reference
to a BSS alive for the auth process. Remove the
old version of cfg80211_ref_bss() since it's
not actually used.

Subject: mac80211: redesign auth/assoc

This is the second part of the auth/assoc redesign,
the mac80211 part. This moves the auth/assoc code
out of the work abstraction and into the MLME, so
that we don't flip channels all the time etc.

The only downside is that when we are associated,
we need to drop the association in order to create
a connection to another AP, but for most drivers
this is actually desirable and the ability to do
was never used by any applications. If we want to
implement resource reservation with FT-OTA, we'd
probably best do it with explicit R-O-C in wpa_s.

Subject: bcma: make some functions __devinit

bcma_core_pci_hostmode_init() has to be in __devinit as it will call a
function in that section and so all functions calling it also have to
be in __devinit.

Subject: bcma: add PCIe host controller

Some SoCs have a PCIe host controller to make it possible to attach
some other devices to it, like an other Wifi card.
This code was tested with an Netgear WNDR3400 (bcm4716 based), but
should work with all bcma based SoCs.

In set_channel() callback handler, "priv" pointer is derived from

This patch fixes the problem by deriving "priv" from wiphy

Subject: mac80211: support hw scan while idle

Currently, mac80211 goes to idle-off before starting a scan.
However, some devices that implement hw scan might not
need going idle-off in order to perform a hw scan, and
thus saving some energy and simplifying their state machine.

(Note that this is also the case for sched scan - it
currently doesn't make mac80211 go idle-off)

Add a new flag to indicate support for hw scan while idle.

Subject: rtlwifi: Fix PCI probe error path orphaned memory

Memory allocated by ieee80211_alloc_hw() will get orphaned
if any subsequent initializations fail.

Also don't pci_set_drvdata(pdev, NULL) until just before disabling
the PCI device. Functions called by rtl_deinit_core(hw) may eventually need
the context (when its actually implemented).

Subject: mwifiex: update correct dtim_period in dump_station()

Earlier we were using dtim period extracted from scan response
buffer provided by FW in scan operation. But it is observed that
sometimes the buffer doesn't contain dtim period tlv, and wrong
value (0) was sent to user space.

After association FW will start listening to beacon frames of
connected AP and store dtim period. Therefore we can get it from
FW in dump_station() instead of using wrong value obtained in
scanning.

Redundant code after adapting new approach for dtim period is
also removed in this patch.

Subject: mac80211: call rate control only after init

There are situations where we don't have the
necessary rate control information yet for
station entries, e.g. when associating. This
currently doesn't really happen due to the
dummy station handling; explicitly disabling
rate control when it's not initialised will
allow us to remove dummy stations.

Subject: orinoco: Remove old mailing lists from MAINTAINERS

The two orinoco mailing lists on sourceforge were set up many years
ago and are now more or less moribund.  I'd like to shut them down, so
I don't have to keep filtering the spam from them (which is most of
what comes through now).  In preparation, this patch removes the
reference to them from the MAINTAINERS file.  Any remaining discussion
of this approaching obsolete driver can go to the linux-wireless list.

Subject: rt2x00: Introduce concept of driver data in struct rt2x00_dev.

We are getting more and more fields in struct rt2x00_dev that are
specific to one or two of the low-level drivers. Instead of putting
these fields inside the main structure and thus clobbering all low-level
drivers with these fields, introduce the concept of driver data inside
struct rt2x00_dev, whose size is indicated by the low-level driver and
which can be populated by the low-level driver.

Subject: rt2x00: Update comment on freq_offset field in struct rt2x00_dev.

The comment states that the field is only used for rt61pci and rt73usb.
However, it is now used by rt2800pci and rt2800usb as well, so the
comment is not correct anymore.

Update the comment to not state any low-level drivers anymore.

Subject: mac80211: rename mesh static path_lookup()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If you want to use mesh support from mac80211 on a recent
kernel on 2.6.24 you'll run into a name clash when compiling
against include/linux/namei.h, so rename this routine.

/home/mcgrof/tmp/compat-wireless-3.2.5-1/net/mac80211/mesh_pathtbl.c: At top level:
/home/mcgrof/tmp/compat-wireless-3.2.5-1/net/mac80211/mesh_pathtbl.c:342:26: error: conflicting types for ‘path_lookup’
include/linux/namei.h:71:12: note: previous declaration of ‘path_lookup’ was here

Although this could sit as a separate patch in compat-wireless it seems
best to just merge upstream.

Callers of rtl_pci_init expect zero to be returned on error. Returning
the error code leads to, amongst other things, divide by zero panics
attempting to use the ring size that is set to zero.

Subject: Bluetooth: Fix l2cap conn failures for ssp devices

Commit 330605423c fixed l2cap conn establishment for non-ssp remote
devices by not setting HCI_CONN_ENCRYPT_PEND every time conn security
is tested (which was always returning failure on any subsequent
security checks).

However, this broke l2cap conn establishment for ssp remote devices
when an ACL link was already established at SDP-level security. This
fix ensures that encryption must be pending whenever authentication
is also pending.

Subject: Bluetooth: l2cap_set_timer needs jiffies as timeout value

After moving L2CAP timers to workqueues l2cap_set_timer expects timeout
value to be specified in jiffies but constants defined in miliseconds
are used. This makes timeouts unreliable when CONFIG_HZ is not set to
1000.

__set_chan_timer macro still uses jiffies as input to avoid multiple
conversions from/to jiffies for sk_sndtimeo value which is already
specified in jiffies.

Subject: Bluetooth: silence lockdep warning

Since bluetooth uses multiple protocols types, to avoid lockdep
warnings, we need to use different lockdep classes (one for each
protocol type).

This is already done in bt_sock_create but it misses a couple of cases
when new connections are created. This patch corrects that to fix the
following warning:

Subject: Bluetooth: Fix potential deadlock

We don't need to use the _sync variant in hci_conn_hold and
hci_conn_put to cancel conn->disc_work delayed work. This way

This issue has been brought up earlier here:

https://lkml.org/lkml/2011/5/21/127

The issue appears to be the rfcomm_session_put in rfcomm_recv_ua. This
operation doesn't seem be to required as for the non-initiator case we
have the rfcomm_process_rx doing an explicit put and in the initiator
case the last dlc_unlink will drive the reference counter to 0.

There have been several attempts to fix these issue:

6c2718d Bluetooth: Do not call rfcomm_session_put() for RFCOMM UA on closed socket
683d949 Bluetooth: Never deallocate a session when some DLC points to it

but AFAICS they do not fix the issue just make it harder to reproduce.

Subject: Bluetooth: Remove usage of __cancel_delayed_work()

__cancel_delayed_work() is being used in some paths where we cannot
sleep waiting for the delayed work to finish. However, that function
might return while the timer is running and the work will be queued
again. Replace the calls with safer cancel_delayed_work() version
which spins until the timer handler finishes on other CPUs and
cancels the delayed work.

Subject: mac80211: call rate control only after init

There are situations where we don't have the
necessary rate control information yet for
station entries, e.g. when associating. This
currently doesn't really happen due to the
dummy station handling; explicitly disabling
rate control when it's not initialised will
allow us to remove dummy stations.

Subject: mac80211: do not call rate control .tx_status before .rate_init

Most rate control implementations assume .get_rate and .tx_status are only
called once the per-station data has been fully initialized.
minstrel_ht crashes if this assumption is violated.

Subject: mwifiex: clear previous security setting during association

Driver maintains different flags for WEP, WPA, WPA2 security modes.
Appropriate flag is set using security information provided in
connect request. mwifiex_is_network_compatible() routine uses them
to check if driver's setting is compatible with AP. Association is
aborted if the routine fails.

For some corner cases, it is observed that association is failed
even for valid security information based on association history.
This patch fixes the problem by clearing previous security setting
during each association.

We should set WEP key provided in connect request as default tx key.
This missing change is also added here.

Subject: ath9k: stop on rates with idx -1 in ath9k rate control's .tx_status

Rate control algorithms are supposed to stop processing when they
encounter a rate with the index -1.  Checking for rate->count not being
zero is not enough.

Allowing a rate with negative index leads to memory corruption in
ath_debug_stat_rc().

One consequence of the bug is discussed at
https://bugzilla.redhat.com/show_bug.cgi?id=768639
