mac80211: probe unexercised mesh links

2019-04-26T11:02:11Z

The requirement for mesh link metric refreshing, is that from one mesh point we be able to send some data frames to other mesh points which are not currently selected as a primary traffic path, but which are only 1 hop away. The absence of the primary path to the chosen node makes it necessary to apply some form of marking on a chosen packet stream so that the packets can be properly steered to the selected node for testing, and not by the regular mesh path lookup.

mac80211: store tx power value from user to station

2019-04-26T11:02:11Z

This patch introduce a new driver callback drv_sta_set_txpwr. This API will copy the transmit power value passed from user space and call the driver callback to set the tx power for the station.

mac80211: IEEE 802.11 Extended Key ID support

2019-04-26T11:02:11Z

Add support for Extended Key ID as defined in IEEE 802.11-2016. - Implement the nl80211 API for Extended Key ID - Extend mac80211 API to allow drivers to support Extended Key ID - Enable Extended Key ID by default for drivers only supporting SW crypto (e.g. mac80211_hwsim) - Allow unicast Tx usage to be supressed (IEEE80211_KEY_FLAG_NO_AUTO_TX) - Select the decryption key based on the MPDU keyid - Enforce existing assumptions in the code that rekeys don't change the cipher Signed-off-by: Alexander Wetzel [remove module parameter] Signed-off-by: Johannes Berg

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

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
