2013-05-24ath9k_hw: improve performance for AR934x v1.3+Felix Fietkau
AR934x v1.3 no longer needs the DCU backoff reduction workaround for preventing rx overruns, but in turn needs the number of usable Tx buffers to be reduced slightly. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2013-05-24ath9k_hw: fix host interface reset on AR934xFelix Fietkau
If a local bus timeout has been detected, the host interface needs to be reset to clear the errors. AR934x uses a different synchronous interrupt bit to indicate this, so the check needs to be fixed.

2013-05-23mac80211: fix queue handling crashJohannes Berg
The code I added in "mac80211: don't start new netdev queues if driver stopped" crashes for monitor and AP VLAN interfaces because while they have a netdev, they don't have queues set up by the driver. To fix the crash, exclude these from queue accounting here and just start their netdev queues unconditionally. For monitor, this is the best we can do, as we can redirect frames there to any other interface and don't know which one that will since it can be different for each frame. For AP VLAN interfaces, we can do better later and actually properly track the queue status. Not doing this is really a separate bug though.

2013-05-22ath9k: prevent aggregation session deadlocksFelix Fietkau
Waiting for all subframes of an existing aggregation session to drain before allowing mac80211 to start a new one is fragile and deadlocks caused by this behavior have been observed. Since mac80211 has proper synchronization for aggregation session start/stop handling, a better approach to session handling is to simply allow mac80211 to start a new session at any time. This requires changing the code to discard any packets outside of the BlockAck window in the A-MPDU software retry code. This patch implements the above and also simplifies the code.

2013-05-17ath9k: fix draining aggregation tid buffersFelix Fietkau
After a tx attempt, an A-MPDU subframe can still have fi->retries at 0 (if the retry count wasn't incremented due to powersave). In that case it is still tracked as part of the block ack window, so when draining the tid queue, its sequence number needs to be cleared from the pending frame bitmap.

2013-05-16iwlwifi: mvm: fix aggregation drain flowEmmanuel Grumbach
Move the counter for non-AMPDU frames to mvm. It is needed for the drain flow which happens once the ieee80211_sta has been freed, so keeping it in iwl_mvm_sta which is embed into ieee80211_sta is not a good idea. Also, since its purpose it to remove the STA in the fw only after all the frames for this station have exited the shared Tx queues, we need to decrement it in the reclaim flow. This flow can happen after ieee80211_sta has been removed, which means that we have no iwl_mvm_sta there. So we can't know what is the vif type. Hence, we know audit these frames for all the vif types. In order to avoid spawning sta_drained_wk all the time, we now check that we are in a flow in which draining might happen - only when mvmsta is NULL. This is better than previous code that would spawn sta_drained_wk all the time in AP mode.

2013-05-16mac80211: report deauth to cfg80211 for local state changeJohannes Berg
Even if the frame isn't transmitted to the AP, we need to report it to cfg80211 so the state there can be updated correctly. Reported-by: Jouni Malinen <j@w1.fi> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-05-16cfg80211: fix interface down/disconnect state handlingJohannes Berg
When the interface goes down, there's no need to call cfg80211_mlme_down() after __cfg80211_disconnect() as the latter will call the former (if appropriate.) Also, in __cfg80211_disconnect(), if the cfg80211 SME isn't used, __cfg80211_disconnected() may still need to be called (depending on the current state) so that the SME state gets cleared.

2013-05-16mac80211: fix AP-mode frame matchingJohannes Berg
In AP mode, ignore frames with mis-matched BSSID that aren't multicast or sent to the correct destination. This fixes reporting public action frames to userspace multiple times on multiple virtual AP interfaces.

2013-05-16mac80211: use just spin_lock() in ieee80211_get_tkip_p2k()Johannes Berg
ieee80211_get_tkip_p2k() may be called with interrupts disabled, so spin_unlock_bh() isn't safe and leads to warnings. Since it's always called with BHs disabled already, just use spin_lock().

2013-05-16mac80211: fix HT beacon-based channel switch handlingJohannes Berg
When an HT AP is advertising channel switch in a beacon, it doesn't (and shouldn't, according to 802.11-2012 Table 8-20) include a secondary channel offset element. The only possible interpretation is that the previous secondary channel offset remains valid, so use that when switching channel based only on beacon information. VHT requires the Wide Bandwidth Channel Switch subelement to be present in the Channel Switch Wrapper element, so the code for that is probably ok (see 802.11ac Draft 4, 8.4.2.165.)

2013-05-16mac80211: fix IEEE80211_SDATA_DISCONNECT_RESUMEJohannes Berg
Since commit 12e7f517029dad819c45eca9ca01fdb9ba57616b, IEEE80211_SDATA_DISCONNECT_RESUME no longer worked as it would simply never be tested. Restore a bit of the code removed there and in 9b7d72c1041ec5b20b24af487a9 to make it work again. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-05-16cfg80211: fix WoWLAN wakeup tracingJohannes Berg
If the device reports a non-wireless wakeup reason, the tracing code crashes trying to dereference a NULL pointer. Fix this by checking the pointer on all accesses and also add a non_wireless tag to the event. Cc: stable@vger.kernel.org Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-05-16mac80211_hwsim: correctly register the platform driverSasha Levin

2013-05-16cfg80211: fix wiphy_register error pathJohannes Berg
If rfkill_register() fails in wiphy_register() the struct device is unregistered but everything else isn't (regulatory, debugfs) and we even leave the wiphy instance on all internal lists even though it will likely be freed soon, which is clearly a problem. Fix this by cleaning up properly. Cc: stable@vger.kernel.org Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-05-10Merge branch 'wireless'David S. Miller
John W. Linville says: ==================== Here is a batch of fixes intended for the 3.10 stream. Amitkumar Karwar provides an mwifiex fix to plug a memory leak when the driver is unloaded. Bing Zhao brings an mwifiex fix for some flag handling that leads to log spam and an unusable interface. Daniel Drake offers an mwifiex fix for multicast filter setup, to correctly implement wakeup behaviour for multicast WOL. Felix Fietkau fixes an ath9k problem that produces logspam and keycache errors due to a bad return code. Stanislaw Gruszka produces an fix for a WARNING from ath5k, and an iwl4965 workaround to stop advertising a feature that doesn't work with the current mac80211 implementation. Sujith Manoharan gives us an ath9k fix to reprogram the HW beacon timers after a TSF update, and an initvals fix for the AR9565 device. Thommy Jakobsson fixes an rx descriptor underrun on b43. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
