| * mac80211: serialize rx path workersChristian Lamparter2011-01-041-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses the issue of serialization between the main rx path and various reorder release timers. <http://www.spinics.net/lists/linux-wireless/msg57214.html> It converts the previously local "frames" queue into a global rx queue [rx_skb_queue]. This way, everyone (be it the main rx-path or some reorder release timeout) can add frames to it. Only one active rx handler worker [ieee80211_rx_handlers] is needed. All other threads which have lost the race of "runnning_rx_handler" can now simply "return", knowing that the thread who had the "edge" will also take care of their workload.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch tackles one of the problems of my reorder release timer patch from August. <http://www.spinics.net/lists/linux-wireless/msg57214.html> => What if the reorder release triggers and ap_sta_ps_end (called by ieee80211_rx_h_sta_process) accidentally clears the WLAN_STA_PS_STA flag, because 100ms ago - when the STA was still active - frames were put into the reorder buffer.

* | mac80211: add throughput based LED blink triggerJohannes Berg2010-12-221-0/+13
|/ | | | | | | | | | | | | | | iwlwifi and other drivers like to blink their LED based on throughput. Implement this generically in mac80211, based on a throughput table the driver specifies. That way, drivers can set the blink frequencies depending on their desired behaviour and max throughput. All the drivers need to do is provide an LED class device, best with blink hardware offload.

* cfg80211/mac80211: add mesh join/leave commandsJohannes Berg2010-12-061-13/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Instead of tying mesh activity to interface up, add join and leave commands for mesh. Since we must be backward compatible, let cfg80211 handle joining a mesh if a mesh ID was pre-configured when the device goes up. Note that this therefore must modify mac80211 as well since mac80211 needs to lose the logic to start the mesh on interface up. We now allow querying mesh parameters before the mesh is connected, which simply returns defaults. Setting them (internally renamed to "update") is only allowed while connected. Specify them with the new mesh join command instead where needed. In mac80211, beaconing must now also follow the mesh enabled/not enabled state, which is done by testing the mesh ID.

* mac80211: speed up AP probing using nullfunc framesFelix Fietkau2010-12-061-1/+2
| | | | | | | | | | | If the nullfunc frame used to probe the AP was not acked, there is no point in waiting for the probe timeout, so advance to the next try (or disconnect) immediately. If we do reach the probe timeout without having received a tx status, the connection is probably really bad and worth disconnecting.

* mac80211: use nullfunc instead of probe request for connection monitoringFelix Fietkau2010-11-241-0/+2
| | | | | | | | | | | | | | | nullfunc frames are better for connection monitoring, because probe requests are answered even if the AP has already dropped the connection, whereas nullfunc frames from an unassociated station will trigger a disassoc/deauth frame from the AP (WLAN_REASON_CLASS3_FRAME_FROM_NONASSOC_STA), which allows the station to reconnect immediately instead of waiting until it attempts to transmit the next unicast frame. This only works on hardware with reliable tx ACK reporting, any other hardware needs to fall back to the probe request method. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

* mac80211: calculate beacon loss time accuratelyFelix Fietkau2010-11-241-0/+1
| | | | | | | | | | | Instead of using a fixed 2 second timeout, calculate beacon loss interval from the advertised beacon interval and a frame count. With this beacon loss happens after N (default 7) consecutive frames are missed which for a typical setup (100TU beacon interval) is ~700ms (or ~1/3 previous).

* mac80211: fix powersaving clients racesJohannes Berg2010-11-171-0/+3
| | | | | | | | | | | | | | | | | | | | | | The code to handle powersaving stations has a race: when the powersave flag is lifted from a station, we could transmit a packet that is being processed for TX at the same time right away, even if there are other frames queued for it. This would cause frame reordering. To fix this, lift the flag only under the appropriate lock that blocks TX. Additionally, the code to allow drivers to block a station while frames for it are on the HW queue is never re-enabled the station, so traffic would get stuck indefinitely. Fix this by clearing the flag for this appropriately. Finally, as an optimisation, don't do anything if the driver unblocks an already unblocked station.

* mac80211: Add function to get probe request template for current APJuuso Oikarinen2010-11-161-0/+4
| | | | | | | | | | | | | | | | | Chipsets with hardware based connection monitoring need to autonomically send directed probe-request frames to the AP (in the event of beacon loss, for example.) For the hardware to be able to do this, it requires a template for the frame to transmit to the AP, filled in with the BSSID and SSID of the AP, but also the supported rate IE's. This patch adds a function to mac80211, which allows the hardware driver to fetch this template after association, so it can be configured to the hardware.

* mac80211: avoid transmitting delBA to old APJohannes Berg2010-10-061-5/+7
| | | | | | | | | | | | | | | | | When roaming while we have active BA session, we can end up transmitting delBA frames to the old AP while we're already on the new AP's channel, which can cause warnings. Simply avoid sending those frames, but still tear down the internal session state, since they are not really necessary anyway as we will implicitly disassociate when sending the association to the new AP.

| | | | | | | | | | | | | | | | The locking around ieee80211_recalc_smps is buggy -- it cannot acquire another interface's mutex while the iflist mutex is held because another code path could be holding the iface mutex and trying to acquire the iflist mutex.

* mac80211: Add validity check for beacon_crc valueJuuso Oikarinen2010-10-051-0/+1
| | | | | | | | | | | | | | | | | | | | | On association to an AP, after receiving beacons, the beacon_crc value is set. The beacon_crc value is not reset in disassociation, but the BSS data may be expired at a later point. When associating again, it's possible that a beacon for the AP is not received, resulting in the beacon_ies to remain NULL. After association, further beacons will not update the beacon data, as the crc value of the beacon has not changed, and the beacon_crc still holds a value matching the beacon. The beacon_ies will remain forever null. One of the results of this is that WLAN power save cannot be entered, the STA will remain foreven in active mode. Fix this by adding a validation flag for the beacon_crc, which is cleared on association.

The patch not only broke the optimisation, it also introduced a bug: under some (common!) circumstances the flag will be set on an already freed skb! However, investigating this in more detail, I found that most of the flags that we set should be per packet, _except_ for this one, due to a-MPDU processing. Additionally, the flags used for processing (currently just this one) need to be reset before processing a new packet. Since we haven't actually seen bugs reported as a result of the wrong flags handling (which is not too surprising -- the only real bug case I can come up with is an a-MSDU contained in an a-MPDU), I'll make a different fix for rc.

* mac80211: fix offchannel queue stopJohannes Berg2010-08-271-0/+3
| | | | | | | | | | | | | | | | | | | | | | | Somebody noticed this problem, and I outlined to them how to fix it, but haven't heard back from them. So while I was adding the state field I figured I could use it to fix it. The problem, as I understand it, is that when we go offchannel while the driver has a queue stopped, the driver will likely start draining the queue and then enable it while offchannel. This in turn will enable the interface queue, and that leads to transmitting data frames on the wrong channel. Fix this by keeping track of offchannel status per interface, and not enabling the interface queues on interfaces that are offchannel when the driver enables a queue.

* | | | | mac80211: proper IBSS lockingJohannes Berg2010-07-211-5/+2
| |_|_|/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | IBSS has never had locking, instead relying on some memory barriers etc. That's hard to get right, and I think we had it wrong too until the previous patch. Since this is not performance sensitive, it doesn't make sense to have the maintenance overhead of that, so add proper locking.
