This adds need_update and write_actual to rx_queue and need_update and an HCMD indicator to tx_queue.

This allows to use the firmware monitor. This capability uses a lot of contiguous memory (up to 64MB), so make its usage module parameter dependent.

2014-06-24iwlwifi: mvm: rework sched scan channel configurationEliad Peller
The current sched scan channel configuration code configures all the supported channels for scanning. However, this can result in SYSASSERT in some cases, when the configured channel is disabled. Instead, configure only the channels given in the req struct, and set the channel_count field appropriately.

2014-06-23mac80211: protect TDLS discovery sessionArik Nemtsov
After sending a TDLS discovery-request, we expect a reply to arrive on the AP's channel. We must stay on the channel (no PSM, scan, etc.), since a TDLS setup-response is a direct packet not buffered by the AP. Add a new mac80211 driver callback to allow discovery session protection.

2014-06-23mac80211: implement proper Tx path flushing for TDLSArik Nemtsov
As the spec mandates, flush data in the AP path before transmitting the first setup frame. Data packets transmitted during setup are already dropped in the Tx path. For the teardown flow, flush all packets in the direct path before transmitting the teardown frame. Un-authorize the peer sta after teardown is sent, forcing all subsequent Tx to the peer through the AP. Make sure to flush the queues when disabling the link to get the teardown packet out.

2014-06-23mac80211: stop only the queues assigned to the vif during channel switchLuciano Coelho
Instead of stopping all the hardware queues during channel switch, which is especially bad when we have large CSA counts, stop only the queues that are assigned to the vif that is performing the channel switch.

2014-06-23mac80211: add functions to stop and wake all queues assigned to a vifLuciano Coelho
In some cases we may want to stop the queues of a single vif (for instance during a channel-switch). Add a function that stops all the queues that are assigned to a vif. If a queue is assigned to more than one vif, the corresponding netdev subqueue of the other vif(s) will also be stopped. If the HW doesn't set the IEEE80211_HW_QUEUE_CONTROL flag, then all queues are stopped. Also add a corresponding function to wake the queues of a vif back.

2014-06-23mac80211: introduce refcount for queue_stop_reasonsLuciano Coelho
Sometimes different vifs may be stopping the queues for the same reason (e.g. when several interfaces are performing a channel switch). Instead of using a bitmask for the reasons, use an integer that holds a refcount instead. In order to keep it backwards compatible, introduce a boolean in some functions that tell us whether the queue stopping should be refcounted or not. For now, use not refcounted for all calls to keep it functionally the same as before. Signed-off-by: Luciano Coelho <luciano.coelho@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2014-06-23mac80211: use csa counter offsets instead of csa_activeMichal Kazior
vif->csa_active is protected by mutexes only. This means it is unreliable to depend on it on codeflow in non-sleepable beacon and CSA code. There was no guarantee to have vif->csa_active update be visible before beacons are updated on SMP systems. Using csa counter offsets which are embedded in beacon struct (and thus are protected with single RCU assignment) is much safer.

Currently, cfg80211 tries to implement ethtool, but that doesn't really scale well, with all the different operations. Make the lower-level driver responsible for it, which currently only has an effect on mac80211. It will similarly not scale well at that level though, since mac80211 also has many drivers.

2014-06-23mac80211: remove ignore_plink_timer flagBob Copeland
The mesh_plink code is doing some interesting things with the ignore_plink_timer flag. It seems the original intent was to handle this race: cpu 0 cpu 1 ----- ----- start timer handler for state X acquire sta_lock change state from X to Y mod_timer() / del_timer() release sta_lock acquire sta_lock execute state Y timer too soon However, using the mod_timer()/del_timer() return values to detect these cases is broken. As a result, timers get ignored unnecessarily, and stations can get stuck in the peering state machine. Instead, we can detect the case by looking at the timer expiration. In the case of del_timer, just ignore the timers in the following (LISTEN/ESTAB) states since they won't have timers anyway.

2014-06-23mac80211: fix station/driver powersave raceJohannes Berg
It is currently possible to have a race due to the station PS unblock work like this: * station goes to sleep with frames buffered in the driver * driver blocks wakeup * station wakes up again * driver flushes/returns frames, and unblocks, which schedules the unblock work * unblock work starts to run, and checks that the station is awake (i.e. that the WLAN_STA_PS_STA flag isn't set) * we process a received frame with PM=1, setting the flag again * ieee80211_sta_ps_deliver_wakeup() runs, delivering all frames to the driver, and then clearing the WLAN_STA_PS_DRIVER and WLAN_STA_PS_STA flags In this scenario, mac80211 will think that the station is awake, while it really is asleep, and any TX'ed frames should be filtered by the device (it will know that the station is sleeping) but then passed to mac80211 again, which will not buffer it either as it thinks the station is awake, and eventually the packets will be dropped. Fix this by moving the clearing of the flags to exactly where we learn about the situation. This creates a problem of reordering, so introduce another flag indicating that delivery is being done, this new flag also queues frames and is cleared only while the spinlock is held (which the queuing code also holds) so that any concurrent delivery/TX is handled correctly.
