2014-07-21wireless: fixup genregdb.awk for remove of antenna gain from wireless-regdLuis R. Rodriguez2-13/+28
Since "wireless-regdb: remove antenna gain" was merged in the wireless-regdb tree, the awk script parser has been incompatible with the 'official' regulatory database. This fixes that up. Without this change the max EIRP is set to 0 making 802.11 devices useless. The fragile nature of the awk parser must be replaced, but ideas over how to do that in the most scalable way are being reviewed. In the meantime update the documentation for CFG80211_INTERNAL_REGDB so folks are aware of expectations for now.

2014-07-21mac80211: remove redundant IEEE80211_STA_CSA_RECEIVED flagLuciano Coelho2-8/+1
The csa_active flag was added in sdata a while ago and made IEEE80211_STA_CSA_RECEIVED redundant. The new flag is also used to mark when CSA is ongoing on other iftypes and took over the old one as the preferred method for checking whether we're in the middle of a channel switch.

2014-07-21mac80211: make sure TDLS teardown packet is sent on timeLiad Kaufman1-0/+11
Since the teardown packet is created while the queues are stopped, it isn't sent immediately, but rather is pending.

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.

2014-06-23mac80211: fix station/driver powersave raceJohannes Berg4-29/+51
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.
