Subject: ath6kl: handle concurrent AP-STA channel switches

If an ath6kl AP vif is beaconing on one channel, and a STA vif
associates on a different channel, a WMI_DISCONNECT event will be sent
to the AP vif. Make the AP vif follow the STA interface, and notify
userspace.

kvalo: fix a sparse warning with vif->next_chan

If, in

the call to wait_for_completion_interruptible() returns -ERESTARTSYS
then we'll return without freeing the (as yet unused) memory we

Subject: ath6kl: list_first_entry() is never NULL

We can remove the NULL check here.  It triggers a Smatch warning because
list_first_entry() never is NULL and people who check for it normally
intend to check for list_empty() instead.  In these cases however,
we've already verified that the lists are not empty.

Subject: ath6kl: Configure probed SSID list consistently

Set max_scan_ssids and max_sched_scan_ssids to same value. These use the
same probed SSID list, so there is no point in using different maximum
number of SSIDs.

Clear probed SSID entries that are not used. This was already done for
sched_scan, but not for scan. Be consistent and clear the table for both
cases to avoid leaving bogus entries.

In addition, share the same function for setting the probed SSIDs for
scan and sched_scan paths. This fixes setting of wildcard SSID flag
(ANY_SSID_FLAG) and changes the scan path to use probed SSID index
consistently (i.e., start with 0 similarly to sched_scan; firmware
will handle the needed internal mapping).

Subject: ath6kl: support fw reporting phy capabilities

Currently the supported bands are just hard coded in the driver.
However, the ath6kl FW will include its 11n and band capabilites in a

Subject: ath6kl: Multicast filter support in wow suspend and non-suspend

This patch enables all multicast packets in non suspend mode
and enable multicast filtering in wow suspend mode. This also
fixes a bug in multicast where the driver assumed disable
multicast-all command disabled/filtered all multicast
packets, which was wrong assumption, because firmware will
apply the programmed filter.

Multicast requirements
 - Enable forward all multicast packets(no filtering) in
      non suspend mode.
 - Enable multicast filtering in wow suspend mode for both
      AP and CLIENT.

Subject: ath6kl: Fix bss filter setting while scanning

bss filter is configured to allow the frames from all the bss other
than the currenly connected one, this is done when a scan is requested
in connected state. There is no reason to filter out the currently
connected bss, configure the filter to allow all the bss. This would
fix the reporting of stale rssi of the current bss while scanning.

Subject: ath6kl: handle background(BK) stream properly on htc mbox layer

When a STA sends huge BK QoS data frame first and then sends BE/VI/VO
QoS data frame, the corresponding throughput becomes much lower than
that without sends BK QoS data frame before.

The root cause is that when station send BK stream, the tx credits of
BK stream don't return back to higher priority QoS stream such as BE,
VI, and VO stream. This patch will handle BK stream properly, when
there is higher priority QoS stream, it will seek tx credits from BK
stream properly.

On the htc mbox layer, it will assign each endpoint (AC) with a
different Tx-packet-drop threshold, so lower priority AC is more
likely to drop packets and the cookies become more available to higher
priority AC.

On the htc pipe layer, assign the tx packet drop threshold as well, it
will let AC to drop packets when cookies below the tx packet drop
threshold.

Subject: ath6kl_sdio: Fix the EAPOL out of order issue

Send the EAPOL and management frames in the same AC_VO queue. The issue
happens when the AP supports QOS, the management frames are sent to AC_VO
queue and EAP frame goes to AC_BE queue. Even though the EAP frame is
queued before the DEAUTH management frame, as they are queued on different
h/w queues, order of delivery between these frames cannot be controlled.

This fixes the connection failure seen in P2P case.

Subject: Bluetooth: Remove redundant hdev->parent field

We initialize the "struct device" in hci_alloc_dev() for a long time now
so we can access hdev->dev.parent directly. Hence, we can drop the
temporary field hdev->parent which is used in no other place than
hci_add_sysfs().

SET_HCIDEV_DEV() is never called after registering a device by the
drivers so we do not overwrite internal device-state. Furthermore,
hdev->dev is initialized to 0 by kzalloc() inside hci_alloc_dev() so the
default behavior with dev.parent = NULL is kept.

Subject: Bluetooth: vhci: Ignore return code of nonseekable_open()

The comment in ./fs/open.c clearly states that nonseekable_open() will
never fail. Therefore, we can safely ignore the return code. This is the
recommended way to deal with nonseekable_open().
Our current code looks like nonseekable_open() is checked for the return
code. However, if we check the return code, we must also kfree() our
private data if the open fails. To avoid this overhead and to avoid
confusion, we simply drop the return code and return 0.

Subject: Bluetooth: btmrvl_sdio: remove pointless conditional before
 release_firmware()

release_firmware() deals gracefullt with NULL pointers so there's no
reason to test for one prior to calling the function.

Subject: Bluetooth: btmrvl: configure default host sleep parameters

Currently debugfs commands "hscfgcmd" and "gpiogap" are provided
for host sleep configuration. But if user doesn't configure host
sleep parameters using these commands, host sleep activation is
failed during suspend (support for suspend and resume handlers is
added in next patch).

Default host sleep configuration is done during driver initialisation
in this patch.

Subject: mac80211_hwsim: Fix rate control by correctly reporting transmission
 counts

Drivers need to report the number of transmission attempts for each rate
as well as to terminate the rate array with -1.  The in-kernel datapath
of hwsim simulates a perfect medium, therefore the driver only needs to
report that the first transmission attempt was sucessfully completed at
the most favorable rate.

Rate control is working again for this driver.  Tested mesh mode with
minstrel.

Subject: iwlwifi: don't disable AGG queues that are not enabled

If the BA session is torn down before we had a chance to start it
we shouldn't disable the AGG tx queues that weren't enabled.
This can happen in two cases:

1) We get a delBA before we drained our Tx queues in agg start flow
2) We didn't get the (successfull) addBA response on time

Subject: ath9k_hw: Fix RTT calibration

This patch fixes multiple issues with the current RTT
implementation in ath9k.

* The data that is obtained from the RTT interface registers
  are stored in 31:5 - mask out the extra bits when reading them.

* A history buffer is maintained which is not needed at all.
  Remove this array and just store the baseband data for each
  chain (or bank).

* A 'num_readings' variable was being used to handle the
  last entry. But it was being used in an improper manner, with
  the result that the RTT values were never being written
  to the RTT Interface registers. Fix this by using a simple
  flag.

* Stop baseband operations before programming the calibration values
  to the HW.

* Do not restore RX gain settings as part of RTT.

Subject: brcmfmac: remove unused parameter of brcmf_sdcard_reg_read

The size parameter for brcmf_sdcard_reg_read is always 4. Remove it
to make the code neat.

Subject: brcmfmac: decouple set_sbaddr_window from register write interface

brcmf_sdcard_set_sbaddr_window configures 3 registers on SDIO
function misc bank to change current silicon backplane programming
window. This patch makes it call brcmf_sdioh_request_byte directly
in order to prepare for the write register interface unification.

Subject: brcmfmac: introduce unified register access interface for SDIO

Both brcmf_sdcard_cfg_read/write and brcmf_sdcard_reg_read/write
are used as interface functions for register access of SDIO WiFi
dongle. A unified interface brcmf_sdio_regr/w is introduced in
this patch in order to simplify the interface and keep the
complexity within the lower layer.

Subject: brcmfmac: replace brcmf_sdcard_cfg_read with brcmf_sdio_regrb

Use the newly introduced brcmf_sdio_regrb to replace
brcmf_sdcard_cfg_read as part of the SDIO WiFi dongle register
access interface clean up.

Subject: brcmfmac: replace brcmf_sdcard_cfg_write with brcmf_sdio_regwb

Use the newly introduced brcmf_sdio_regwb to replace
brcmf_sdcard_cfg_write as part of the SDIO WiFi dongle register
access interface clean up.

Subject: brcmfmac: replace brcmf_sdcard_reg_read with brcmf_sdio_regrl

Use the newly introduced brcmf_sdio_regrl to replace
brcmf_sdcard_reg_read as part of the SDIO WiFi dongle register
access interface clean up.

Subject: brcmfmac: remove redundant retries for SDIO core register access

The new brcmf_sdio_regrl/regwl interface has already performed
retries on failed attempts. It is no longer necessary to have the
retry mechanism in r_sdreg32/w_sdreg32.

Subject: brcmfmac: remove function brcmf_sdcard_regfail

The new interface brcmf_sdio_regr/w provides result of access
attempts. It is no longer necessary to use dedicated variable
and function to provide enquiry for failure.

Subject: b43legacy: Fix error due to MMIO access with SSB unpowered

There is a dummy read of a PCI MMIO register that occurs before the SSB bus
has been powered, which is an error. This bug has not been seen earlier,
but was apparently exposed when udev was updated to version 182.

Subject: NFC: Cache the core NFC active target pointer instead of its index

The NFC Core now caches the active nfc target pointer, thereby avoiding
the need to lookup the target table for each invocation of a driver ops.
Consequently, pn533, HCI and NCI now directly receive an nfc_target
pointer instead of a target index.

Subject: NFC: Remove unneeded pn533 dev NULL check

container_of() works by subtracting the offset of the member.  The math
can't really return a zero here.  Sometimes people check it when they
actually meant to check something else but in this case we can just
remove the check.

Subject: wlcore: use GFP_KERNEL together with GFP_DMA

GFP_DMA should not be used by itself, it still needs GFP_KERNEL or
such.  Fix two occurrences of allocations with GFP_DMA only.

Subject: wl12xx: support wowlan wakeup patterns

Use FW RX data filters to support cfg80211 wowlan wakeup patterns.
This enables to wake up the host from suspend following detection
of certain configurable patterns within an incoming packet.
Up to 5 patterns are supported. Once the host is resumed
any configured RX data filter is cleared.
A single pattern can match several bytes sequences with different
offsets within a packet.

Subject: wireless: TI wlxxx depends on MAC80211

wl12xx build fails with many undefined symbol errors when MAC80211
and CFG80211 are not enabled, so make WLCORE and WL12XX depend
on MAC80211 (which already depends on CFG80211).

Subject: wlcore: fix size of two memset's in wl1271_cmd_build_arp_rsp()

We currently do this:

int wl1271_cmd_build_arp_rsp(struct wl1271 *wl, struct wl12xx_vif *wlvif)
...
      struct wl12xx_arp_rsp_template *tmpl;
      struct ieee80211_hdr_3addr *hdr;
...
      tmpl = (struct wl12xx_arp_rsp_template *)skb_put(skb, sizeof(*tmpl));
      memset(tmpl, 0, sizeof(tmpl));
...
      hdr = (struct ieee80211_hdr_3addr *)skb_push(skb, sizeof(*hdr));
      memset(hdr, 0, sizeof(hdr));
...

I believe we want to set the entire structures to 0 with those
memset() calls, not just zero the initial part of them (size of the
pointer bytes).

Subject: ssb: remove rev from boardinfo

Previously the rev contained the revision read from the pci config
space and was used as board_rev in the wireless drivers. This is wrong
the board_rev is only fetched from the sprom accordingly to the open
source part of the Broadcom SDK and brcmsmac. This patch removes the
rev from the boardinfo structure and uses the board_rev attribute from
sprom instead. This attribute is filled by PCI, PCMCIA, SDIO and SoC
code.

Subject: ssb/bcma: fill attribute alpha2 from sprom

The attribute country_code and alpha2 are two different attributes in
the sprom. country_code contains some code in an 8 bit coding and
alpha2 contains two chars with the country code. The attributes where
read out wrongly in the past and country_code is only available on
sprom version 1.

Subject: brcmsmac: remove brcmsmac own sprom parsing

brcmsmac now takes the sprom from bcma and do not uses its own sprom
parsing any more. Remove this code as it is not used any more.

bcma now provide this data and brcmsmac should get it from there and
not parse it by its self.

Subject: brcmsmac: remove support for cc rev < 20

The lowest chip common version used on bcma based devices is 31 on the
bcm4718 and 32 on the bcm4313, bcm43224, and bcm43225, so the support
for the old versions could be removed.

Subject: brcmsmac: remove references to PCI

There are no devices which are using bcma and have a PCI bus, just a
PCIe bus or something else. bcma does not support PCI devices, so lets
also remove PCI support from brcmsmac. All devices currently supported
by brcmsmac are PCIe based.

Subject: brcmsmac: remove PCIe functions needed for PCIe core rev <= 10

The devices I know of are not using a PCIe core with rev <= 10. The
BCM4718 uses a PCIe core with revision 14 and the BCM43224 uses a PCIe
core with revision 15. This patch removes support for old PCIe core
versions, which are not found on devices supported by brcmsmac.

Subject: mwifiex: support for creation of AP interface

1. wiphy structure is per device; hence moved it to mwifiex_adapter
mwifiex_register_cfg80211 takes mwifiex_adapter as parameter.
This function only registers wiphy with cfg80211.
2. Creation of interfaces is moved to cfg80211 add_virtual_interface
handler.
3. Create 2 interfaces by default: station and AP

Subject: mwifiex: save adapter pointer in wiphy_priv

Since wiphy structure is per adapter we would save adapter,
instead of mwifiex private pointer, in wiphy_priv.
Also move country_info from mwifiex_private to mwifiex_adapter
as making it part of mwifiex_adapter looks logical.

Subject: mwifiex: append peer mac address TLV in key material command to
 firmware

Modify key related cfg80211 handlers to copy peer mac address for
pairwise keys. If peer mac address is not present or group keys,
it will be sent as broadcast mac address.
This would be required since hostapd downloads per peer PTK.

Subject: mwifiex: common set_wiphy_params cfg80211 handler for AP and STA
 interface

Add support for setting fragmentation threshold, RTS threshold
and retry limit.
Since wiphy parameters are properties of physical device,
appropriate function to set phy parameters is invoked depending
upon bss_type(STA or AP) for each virtual interface.

Subject: mwifiex: add AP event handling framework

Added logic to handle AP event that are generated
by the firmware. As MLME/SME is implemented in the
firmware, events such as station association and
deauthentication, must be sent to userspace (hostapd)
for creating and deleting station database.

Subject: mwifiex: add WPA2 support for AP

1. Support for parsing security related parameters from
   cfg80211_ap_settings in start_ap cfg80211 handler
2. Conversion of these security information into FW understandle TLVs
   and setting into FW thru sys_config command
3. key management is done on host. This ensures that FW forwards EAPOL
   key packets to host instead of processing on its own.

Subject: mwifiex: add custom IE framework

1. support for setting custom IE from application hostapd etc.
Custom IE addition using auto-indexing and Custom IE deletion using
static indices (which are allocated during IE addition and stored in
driver) are supported.
2. Separate file for handling IE related execution.

Subject: mwifiex: retrieve IEs from cfg80211_beacon_data and send to firmware

This patch adds logic for setting tail beacon IE, probe response IE
and assoc response IE from cfg80211_ap_settings parameter of
start_ap handler into FW.

RSN IE is also retrieved from tail IE buffer and sent to firmware.

Subject: iwlwifi: fix scan_cmd_size allocation

Allocate scan command with dynamic size based on uCode capability
and num of channels.
This isn't an important fix as the previous allocation was always
too large as it added the scan command size but later subtracted
it (which meant it was supposed to be part of the max scan size.)

Subject: iwlwifi: disable default wildcard ssid scan

iwl_fill_probe_request has used to add a wildcard ssid IE to
any probe request template, now it's disabled and it will
send wildcard ssid only for full scan. Instead, the highest
priority ssid is set to the template.
Due to adding high priority SSID to the template, it reduce
IE len, but since we had only 260 bytes for IEs before changing
allocation size to be dynamic, now we should have a bit more room
for IEs.
