mac80211: fix crash with single-queue drivers

2012-08-09T15:22:51+00:00

commit a6f38ac3cc853189705006cc1e0f17ce8467a1df upstream. Larry (and some others I think) reported that with single-queue drivers mac80211 crashes when waking the queues. This happens because we allocate just a single queue for each virtual interface in case the driver doesn't have at least 4 queues, but the code stopping/waking the virtual interface queues wasn't taking this into account.

mac80211: fix error in station state transitions during reconfig

2012-06-04T19:24:56+00:00

As part of hardware reconfig mac80211 tries to restore the station state to its values before the hardware reconfig, but it only goes to the last-state - 1. Fix this off-by-one error.

mac80211: fix ADDBA declined after suspend with wowlan

2012-05-29T17:45:24+00:00

WLAN_STA_BLOCK_BA is set while suspending but doesn't get cleared when resuming in case of wowlan. This causes further ADDBA requests received to be rejected. Fix it by clearing it in the wowlan path as well. Signed-off-by: Eyal Shapira Reviewed-by: Johannes Berg Cc: stable@vger.kernel.org Signed-off-by: John W. Linville

mac80211: add improved HW queue control

2012-04-11T20:23:50+00:00

mac80211 currently only supports one hardware queue per AC. This is already problematic for off-channel uses since if we go off channel while the BE queue is full and then try to send an off-channel frame the frame will never go out. This will become worse when we support multi-channel since then a queue on one channel might be full, but we have to stop the software queue for all channels. That is obviously not desirable. To address this problem allow drivers to register more hardware queues, and allow them to map them to virtual interfaces. When they stop a hardware queue the corresponding AC software queues on the correct interfaces will be stopped as well. Additionally, there's an off-channel queue to solve that problem and a per-interface after-DTIM beacon queue. This allows drivers to manage software queues closer to how the hardware works. Currently, there's a limit of 16 hardware queues. This may or may not be sufficient, we can adjust it as needed. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville
