2013-02-15mac80211: add radar detection command/eventSimon Wunderlich
Add command to trigger radar detection in the driver/FW. Once radar detection is started it should continuously monitor for radars as long as the channel active. If radar is detected usermode notified with 'radar detected' event. Scanning and remain on channel functionality must be disabled while doing radar detection/scanning, and vice versa.

2013-02-15nl80211/cfg80211: add radar detection command/eventSimon Wunderlich
Add new NL80211_CMD_RADAR_DETECT, which starts the Channel Availability Check (CAC). This command will also notify the usermode about events (CAC finished, CAC aborted, radar detected, NOP finished). Once radar detection has started it should continuously monitor for radars as long as the channel is active. This patch enables DFS for AP mode in nl80211/cfg80211.

2013-02-14mwifiex: device specific sleep cookie handling for PCIeAvinash Patil
This patch adds support for handling of PCIe sleep cookie depending upon device properties. Some PCIe devices need sleep cookie probing before accessing HW while some others don't. A new sleep_cookie variable is defined as part of mwifiex_pcie_card_reg strcture and set/reset as per device capability. Sleep cookie is allocated/accessed/freed only when flag sleep_cookie for this particular device is enabled.

This partially reverts commit 44ba973699b831414c3f8eef68ee5a7fe1208a05. rate_control_rate_init assumes the rate_init member of struct rate_control_ops is not NULL therefore not initializing it leads to an oops as soon the driver succesfully associates to an AP. The removal of rate_update from 44ba973699b831414c3f8eef68ee5a7fe1208a05 is ok because rate_update is checked for NULL before being called.

In managed mode, the HT/VHT capabilities aren't set when the station is initially added, so update the station when it is marked associated. In AP/GO mode, the station will typically be added with full capabilities today, but an upcoming change in hostapd may mean a similar scenario as for managed mode, therefore do the update unconditionally.

2013-02-12iwlwifi: mvm: don't wait for session protection to startJohannes Berg
Now that mac80211 no longer starts the auth/assoc timeouts when it transmits the frame, but only when the frame status arrives, we no longer need to wait for the session protection time event to start, we can schedule it and enqueue the auth/assoc frame right away. This reduces the amount of time we block mac80211's workqueue. Also, since now we no longer need different behavior for session protection and P2P time events, refactor the code to have just a common implementation.

Implement proper WoWLAN wakeup and query the wakeup reasons, then report them to userspace. Note that this is tricky: a firmware bug (that has been fixed in later versions) means that the status command response isn't properly closed in hardware and thus won't arrive at the host. Sending another command after it closes the status response but the next command gets stuck, etc. We reset the device after querying though, so this is not a big issue, just makes for strange code.

Replace each valid byte in pattern by 1 and don't care byte by 0: 10110111 1000 (0000) 1st byte of pattern corresponds to lower order bit in first byte of mask.

2013-02-11mac80211: Add flushes before going off-channelSeth Forshee
We've got a couple of races when enabling powersave with an AP for off-channel operation. The first is fairly simple. If we go off-channel before the nullfunc frame to enable PS is transmitted then it may not be received by the AP. Add a flush after enabling off-channel PS to prevent this from happening. The second race is a bit more subtle. If the driver supports QoS and has frames queued when the nullfunc frame is queued, those frames may get transmitted after the nullfunc frame. If PM is not set then the AP is being told that we've exited PS before we go off-channel and may try to deliver frames. To prevent this, add a flush after stopping the queues but before passing the nullfunc frame to the driver.

2013-02-11mac80211: Fix tx queue handling during scansSeth Forshee
Scans currently work by stopping the netdev tx queues but leaving the mac80211 queues active. This stops the flow of incoming packets while still allowing mac80211 to transmit nullfunc and probe request frames to facilitate scanning. However, the driver may try to wake the mac80211 queues while in this state, which will also wake the netdev queues. To prevent this, add a new queue stop reason, IEEE80211_QUEUE_STOP_REASON_OFFCHANNEL, to be used when stopping the tx queues for off-channel operation. This prevents the netdev queues from waking when a driver wakes the mac80211 queues. This also stops all frames from being transmitted, even those meant to be sent off-channel. Add a new tx control flag, IEEE80211_TX_CTL_OFFCHAN_TX_OK, which allows frames to be transmitted when the queues are stopped only for the off-channel stop reason. Update all locations transmitting off-channel frames to use this flag. Signed-off-by: Seth Forshee <seth.forshee@canonical.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-02-11mac80211: remove unused code to mark AP station authenticatedJohannes Berg
When we get to association, the AP station already exists and is marked authenticated, so moving it into IEEE80211_STA_AUTH again is a NOP, remove it. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-02-11mac80211: simplify idle handlingJohannes Berg
Now that we have channel contexts, idle is (pretty much) equivalent to not having a channel context. Change the code to use this relation so that there no longer is a need for a lot of idle recalculate calls everywhere. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-02-11mac80211: remove IEEE80211_HW_SCAN_WHILE_IDLEJohannes Berg
There are only a few drivers that use HW scan, and all of those don't need a non-idle transition before starting the scan -- some don't even care about idle at all. Remove the flag and code associated with it. The only driver that really actually needed this is wl1251 and it can just do it itself in the hw_scan callback -- implement that.

2013-02-11mac80211: remove dynamic PS driver interfaceJohannes Berg
The functions were added for some sort of Bluetooth coexistence, but aren't used, so remove them again. Reviewed-by: Luciano Coelho <coelho@ti.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-02-11mac80211: introduce beacon-only timing dataJohannes Berg
In order to be able to predict the next DTIM TBTT in the driver, add the ability to use timing data from beacons only with the new hardware flag IEEE80211_HW_TIMING_BEACON_ONLY and the BSS info value sync_dtim_count which is only valid if the timing data came from a beacon. The data can only come from a beacon, and if no beacon was received before association it is updated later together with the DTIM count notification.

2013-02-11cfg80211: move TSF into IEsJohannes Berg
While technically the TSF isn't an IE, it can be necessary to distinguish between the TSF from a beacon and a probe response, in particular in order to know the next DTIM TBTT, as not all APs are spec compliant wrt. TSF==0 being a DTIM TBTT and thus the DTIM count needs to be taken into account as well. To allow this, move the TSF into the IE struct so it can be known whence it came.
