mac80211: make ieee80211_schedule_txq schedule empty TXQs

2019-04-08T11:31:31Z

Currently there is no way for the driver to signal to mac80211 that it should schedule a TXQ even if there are no packets on the mac80211 part of that queue. This is problematic if the driver has an internal retry queue to deal with software A-MPDU retry. This patch changes the behavior of ieee80211_schedule_txq to always schedule the queue, as its only user (ath9k) seems to expect such behavior already: it calls this function on tx status and on powersave wakeup whenever its internal retry queue is not empty. Also add an extra argument to ieee80211_return_txq to get the same behavior. This fixes an issue on ath9k where tx queues with packets to retry (and no new packets in mac80211) would not get serviced.

mac80211: rework locking for txq scheduling / airtime fairness

2019-03-29T10:27:44Z

Holding the lock around the entire duration of tx scheduling can create some nasty lock contention, especially when processing airtime information from the tx status or the rx path. Improve locking by only holding the active_txq_lock for lookups / scheduling list modifications. Signed-off-by: Felix Fietkau Acked-by: Toke Høiland-Jørgensen Signed-off-by: Johannes Berg

mac80211: notify driver on subsequent CSA beacons

2019-02-22T12:45:51Z

Some drivers may want to track further the CSA beacons, for example to compensate for buggy APs that change the beacon count or quiet mode during CSA flow. Signed-off-by: Sara Sharon Signed-off-by: Luca Coelho Signed-off-by: Johannes Berg

mac80211: abort CSA if beacon does not include CSA IEs

2019-02-22T12:43:53Z

In case we receive a beacon without CSA IE while we are in the middle of channel switch - abort the operation. Signed-off-by: Sara Sharon Signed-off-by: Luca Coelho Signed-off-by: Johannes Berg

mac80211: support max channel switch time element

2019-02-22T12:42:54Z

2018 REVmd of the spec introduces the max channel switch time element which is optionally included in beacons/probes when there is a channel switch / extended channel switch element. The value represents the maximum delay between the time the AP transmitted the last beacon in current channel and the expected time of the first beacon in the new channel, in TU. Parse the value and pass it to the driver. Signed-off-by: Sara Sharon Signed-off-by: Luca Coelho Signed-off-by: Johannes Berg

mac80211: indicate support for multiple BSSID

2019-02-08T12:56:37Z

Set multi-bssid support flags according to driver support. Signed-off-by: Sara Sharon Signed-off-by: Johannes Berg

mac80211: support multi-bssid

2019-02-08T12:56:37Z

Add support for multi-bssid. This includes: - Parsing multi-bssid element - Overriding DTIM values - Taking into account in various places the inner BSSID instead of transmitter BSSID - Save aside some multi-bssid properties needed by drivers Signed-off-by: Sara Sharon Signed-off-by: Johannes Berg

mac80211: fix missing/malformed documentation

2019-02-01T11:11:13Z

Fix the missing and malformed documentation that kernel-doc and sphinx warn about. While at it, also add some things to the docs to fix missing links. Sadly, the only way I could find to fix this was to add some trailing whitespace. Signed-off-by: Johannes Berg

mac80211: Fix documentation strings for airtime-related variables

2019-02-01T10:04:53Z

There was a typo in the documentation for weight_multiplier in mac80211.h, and the doc was missing entirely for airtime and airtime_weight in sta_info.h. Reported-by: kbuild test robot Signed-off-by: Toke Høiland-Jørgensen Signed-off-by: Johannes Berg

mac80211: Expose ieee80211_schedule_txq() function

2019-01-25T13:05:27Z

Since we reworked ieee80211_return_txq() so it assumes that the caller takes care of logging, we need another function that can be called without holding any locks. Introduce ieee80211_schedule_txq() which serves this purpose. Signed-off-by: Toke Høiland-Jørgensen Signed-off-by: Johannes Berg
