2019-11-20mt76: refactor cc_lock locking schemeLorenzo Bianconi2-13/+19
Read busy counters not holding cc_lock spinlock since usb read can't be performed in interrupt context. Move cc_active and cc_rx counters out of cc_lock since they are not modified in interrupt context. Grab cc_lock updating cur_cc_bss_rx in mt76_airtime_report and do not hold rx_lock in mt76_update_survey. Moreover grab mt76 mutex in mt76_get_survey before running mt76_update_survey.

2019-11-20mt76: mt76x0: eeprom: add support for MAC address from OFPawel Dembicki1-0/+1
mt76x0e driver only supports MAC addresses from calibration data eeprom. Many routers however do not have a valid stock address set in this field. This patch makes it possible to take a MAC address from OF (e.g. from mtd).

2019-11-20mt76: avoid enabling interrupt if NAPI poll is still pendingFelix Fietkau1-3/+1

Cancel the workqueue after the tid has been cleaned up, in order to avoid a possible rescheduling from within the work function. Signed-off-by: Felix Fietkau <[email protected]>
2019-11-20mt76: drop rcu read lock in mt76_rx_aggr_stopFelix Fietkau1-7/+3
A rcu read locked section is not allowed to sleep, and the rcu lock here isn't actually necessary, because we're holding dev->mutex. Fixes an issue when the tid work item is still running while freeing a station or stopping the aggregation session Signed-off-by: Felix Fietkau <[email protected]>
2019-11-20mt76: add missing locking around ampdu actionFelix Fietkau3-0/+6

2019-11-20mt76: do not use devm API for led classdevFelix Fietkau1-1/+10
With the devm API, the unregister happens after the device cleanup is done, after which the struct mt76_dev which contains the led_cdev has already been freed. This leads to a use-after-free bug that can crash the system. Signed-off-by: Felix Fietkau <[email protected]>

2019-11-20mt76: mt7603: switch to a different counter for survey busy timeFelix Fietkau1-1/+1
