2009-05-06p54: call p54_wake_free_queues on every p54_free_skb and p54_rx_frame_sentMax Filippov
Currently queues are stopped when their length reaches their length limit, but are restarted only when the size of freed range of packet buffer is not less than the size of the largest possible packet. This causes permanent queue stop on radio visibility loss in the middle of ping series: there is plenty of room in the packet buffer, but it is never freed more than 3 (size of 'best effort' queue) * 288 (ping packet plus headers) bytes at once.

2009-05-06mac80211: Comment the order of HT RX reorder handler vs. RX handlersJouni Malinen
We are currently processing block ack reordering as a separate task before all other RX handlers. In theory, this is wrong since this step should be done only after duplicate removal (see Figure 6-1 in IEEE 802.11n). However, moving this needs some work and the current situation is not too bad. Add a comment here so that this small detail does not get forgotten and who knows, maybe someone has some extra time to take a look at cleaning this up.

2009-05-06mac80211: Add a timeout for frames in the RX reorder bufferJouni Malinen
This patch allows skbs to be released from the RX reorder buffer in case they have been there for an unexpectedly long time without us having received the missing frames before them. Previously, these frames were only released when the reorder window moved and that could take very long time unless new frames were received constantly (e.g., TCP connections could be killed more or less indefinitely). This situation should not happen very frequently, but it looks like there are some scenarious that trigger it for some reason. As such, this should be considered mostly a workaround to speed up recovery from unexpected siutation that could result in connections hanging for long periods of time. The changes here will only check for timeout situation when adding new RX frames to the reorder buffer. It does not handle all possible cases, but seems to help for most cases that could result from common network usage (e.g., TCP retrying at least couple of times). For more completely coverage, a timer could be used to periodically check whether there are any frames remaining in the reorder buffer if no new frames are received.

2009-05-06iwlagn: disable PS support for iwlagnReinette Chatre
Some issues in PS prevent us from supporting it reliably. When 4965 goes to sleep it stores some data in host DRAM, reads it back when device wakes up. In 4965 there is a problem that the data is not correct when ucode starts using it upon wakeup. For all iwlagn devices there is a problem where command is sent when PS is enabled. At the moment there is a locking problem with priv->lock not being held and thus not requesting nic access correctly. We disable PS until these issues have been resolved.

2009-05-06ath5k: Enable AP modeJiri Slaby
After some debuging we were hitting the following bugs so far... * Due to huge channel list hostapd couldn't get infos from the driver and couldn't set the channel. If we manualy set the channel after hostapd starts (by setting channel to 0 -auto), beacons are sent but they wont show up on scan because they are malformed (they have channel = 0 because hostapd doesn't update the channel info -this is probably a hostapd bug so i'm CCing Jouni) and they get dropped. Bob fixed this by only allowing standard channels to be registered so now hostapd works as expected. * Docs (and HAL source) say that we must write 0 on timer0 when operating on AP mode to start TSF increment but this seems to mess with DBA in many cases and beacon queue never gets started. We fixed that on the previous patch. We have some more things to deal with... * For some reason (hw bug or something else) after restarting hostapd a few times, beacon inteval seems to change from 100ms to a sec (we get one beacon per sec). * We need to set sleep timers on STA mode and enable power saving + support PCF. ...but i think it's time we enable AP support "officialy" so that we can get more feedback from users. I ran ath5k with the mentioned patches + hostapd 0.6.8 and AP mode worked fine (it had some less throughput on my tests than IBSS but it worked).

2009-05-06ath5k: Beaconing fixesNick Kossifidis
* Write next beacon timer even on AP mode since without this we get no beacons + ath9k does it too. Docs say that we must write 0 on this register on AP mode to start TSF increment, we do both to be on the safe side. * Fix num_tx_pending function, we never read the register :P that's why we got all those "beacon queue 7 didn't stop messages". * Put full prioriy on beacon queue, lock all queues with lower priority using the arblock and also bypass any arblock by seting the arblock ignore flag. * For the CAB queue (do we need this thing ?, it seems crap) since it's supposed to fire up after each beacon (we don't use it on driver part, ath9k/MadWiFi does), don't make it DBA gated but instead make it fire after each beacon by using the beacon sent gated flag. * Increase bmiss threshold to 10, that's what we used on MadWiFi for a long time. Also when we have pending frames on the beacon queue (we got a beacon that didn't make it on the air) it's more likely that the beacon queue never started, probably due to faulty DBA setting, so change that "beacon queue didn't stop" message.

2009-05-06mac80211: tell driver when idleJohannes Berg
When we aren't doing anything in mac80211, we can turn off much of the hardware, depending on the driver/hw. Not doing anything, aka being idle, means: * no monitor interfaces * no AP/mesh/wds interfaces * any station interfaces are in DISABLED state * any IBSS interfaces aren't trying to be in a network * we aren't trying to scan By creating a new function that verifies these conditions and calling it at strategic points where the states of those conditions change, we can easily make mac80211 tell the driver when we are idle to save power. Additionally, this fixes a small quirk where a recalculated powersave state is passed to the driver even if the hardware is about to stopped completely. This patch intentionally doesn't touch radio_enabled because that is currently implemented to be a soft rfkill which is inappropriate here when we need to be able to wake up with low latency. One thing I'm not entirely sure about is this: phy0: device no longer idle - in use wlan0: direct probe to AP 00:11:24:91:07:4d try 1 wlan0 direct probe responded wlan0: authenticate with AP 00:11:24:91:07:4d wlan0: authenticated > phy0: device now idle > phy0: device no longer idle - in use wlan0: associate with AP 00:11:24:91:07:4d wlan0: RX AssocResp from 00:11:24:91:07:4d (capab=0x401 status=0 aid=1) wlan0: associated Is it appropriate to go into idle state for a short time when we have just authenticated, but not associated yet? This happens only with the userspace SME, because we cannot really know how long it will wait before asking us to associate. Would going idle after a short timeout be more appropriate? We may need to revisit this, depending on what happens. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
