2013-10-02Bluetooth: Provide high speed configuration optionMarcel Holtmann
Hiding the Bluetooth high speed support behind a module parameter is not really useful. This can be enabled and disabled at runtime via the management interface. This also has the advantage that this can now be changed per controller and not just global. This patch removes the module parameter and exposes the high speed setting of the management interface to all controllers.

2013-10-02Bluetooth: Replace BDADDR_LOCAL with BDADDR_NONEMarcel Holtmann
The BDADDR_LOCAL is a relict from userspace and has never been used within the kernel. So remove that constant and replace it with a new BDADDR_NONE that is similar to HCI_DEV_NONE with all bits set.

2013-10-01regulatory: enable channels 52-64 and 100-144 for world roamingJohannes Berg
If allowed in a country, these channels typically require DFS so mark them as such. Channel 144 is a bit special, it's coming into use now to allow more VHT 80 channels, but world roaming with passive scanning is acceptable anyway. It seems fairly unlikely that it'll be used as the control channel for a VHT AP, but it needs to be present to allow a full VHT connection to an AP that uses it as one of the secondary channels. Also enable VHT 160 on these channels, and also for channels 36-48 to be able to use VHT 160 there. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-10-01mac80211: support reporting A-MSDU subframes individuallyMichal Kazior
Some devices may not be able to report A-MSDUs in single buffers. Drivers for such devices were forced to re-assemble A-MSDUs which would then be eventually disassembled by mac80211. This could lead to CPU cache thrashing and poor performance. Since A-MSDU has a single sequence number all subframes share it. This was in conflict with retransmission/duplication recovery (IEEE802.11-2012: 9.3.2.10). Patch introduces a new flag that is meant to be set for all individually reported A-MSDU subframes except the last one. This ensures the last_seq_ctrl is updated after the last subframe is processed. If an A-MSDU is actually a duplicate transmission all reported subframes will be properly discarded.

2013-09-30ath9k: fix powersave response handling for BA session packetsFelix Fietkau
When a packet is passed from mac80211 to the driver with the IEEE80211_TX_CTL_PS_RESPONSE flag set, it bypasses the normal driver internal queueing and goes directly to the UAPSD queue. When that happens, packets that are part of a BlockAck session still need to be tracked as such inside the driver, otherwise it will create discrepancies in the receiver BA reorder window, causing traffic stalls. This only happens in AP mode with powersave-enabled clients.

2013-09-30mwifiex: fix SDIO interrupt lost issueAmitkumar Karwar
601216e "mwifiex: process RX packets in SDIO IRQ thread directly" introduced a command timeout issue which can be reproduced easily on an AM33xx platform using a test application written by Daniel Mack: https://gist.github.com/zonque/6579314 mwifiex_main_process() is called from both the SDIO handler and the workqueue. In case an interrupt occurs right after the int_status check, but before updating the mwifiex_processing flag, this interrupt gets lost, resulting in a command timeout and consequently a card reset. Let main_proc_lock protect both int_status and mwifiex_processing flag. This fixes the interrupt lost issue.

2013-09-30ath10k: implement firmware IE container supportKalle Valo
Firmware IE containers can dynamically provide various information what firmware supports. Also it can embed more than one image so updating firmware is easy, user just needs to update one file in /lib/firmware/. The firmware API 2 or higher will use the IE container format, the current API 1 will not use the new format but it still is supported for some time. FW API 2 files are named as firmware-2.bin (which contains both firmware and otp images) and API 1 files are firmware.bin and otp.bin. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2013-09-30mac80211: Run deferred scan if last roc_list item is not startedJouni Malinen
mac80211 scan processing could get stuck if roc work for pending, but not started when a scan request was deferred due to such roc item. Normally the deferred scan would be started from ieee80211_start_next_roc(), but ieee80211_sw_roc_work() calls that only if the finished ROC was started. Fix this by calling ieee80211_run_deferred_scan() in the case the last ROC was not actually started. This issue was hit relatively easily in P2P find operations where Listen state (remain-on-channel) and Search state (scan) are repeated in a loop.

2013-09-30mac80211: update sta->last_rx on acked tx framesFelix Fietkau
When clients are idle for too long, hostapd sends nullfunc frames for probing. When those are acked by the client, the idle time needs to be updated. To make this work (and to avoid unnecessary probing), update sta->last_rx whenever an ACK was received for a tx packet. Only do this if the flag IEEE80211_HW_REPORTS_TX_ACK_STATUS is set.
