2020-02-14mt76: clear skb pointers from rx aggregation reorder buffer during cleanupFelix Fietkau1-0/+1
During the cleanup of the aggregation session, a rx handler (or release timer) on another CPU might still hold a pointer to the reorder buffer and could attempt to release some packets. Clearing pointers during cleanup avoids a theoretical use-after-free bug here. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-02-14mt76: mt7603: fix input validation issues for powersave-filtered framesFelix Fietkau1-4/+15
Before extracting the tid out of the packet, check if it was qos-data. Only accept tid values 0-7 Also, avoid accepting the hardware queue as skb queue mapping, it could lead to an overrun. Instead, derive the hardware queue from the tid number, in order to avoid issues with packets being filtered multiple times. This also fixes a mismatch between hardware and software queue indexes.

2020-02-14mt76: speed up usb bulk copyMarkus Theil2-7/+19
Use larger batches for usb copy to speed this operation up. Otherwise it would be too slow for copying new beacons or broadcast frames over usb.

2020-02-14mt76: mt76x02: remove a copy call for usb speedupMarkus Theil1-4/+15
This patch removes a mt76_wr_copy call from the beacon path to hw. The skb which is used in this place gets therefore build with txwi inside its data. For mt76 usb drivers, this saves one synchronuous copy call over usb, which lets the beacon work complete faster. In mmio case, there is not enough headroom to put the txwi into the skb, it is therefore using an additional mt76_wr_copy, which is fast over mmio. Thanks Stanislaw for pointing this out.

2020-02-14mt76: mt76x02: add check for invalid vif idxMarkus Theil1-1/+3

2020-02-14mt76: mt76x02: split beaconingMarkus Theil6-65/+28
Sending beacons to the hardware always happens in batches. In order to speed up beacon processing on usb devices, this patch splits out common code an calls it only once. Beacons are sequentially written into the beacon memory area, by tracking its usage with the dev->beacon_data_count. For MBSS support and buffered traffic dev->beacon_data_count is used to create the bypass mask. The code is also adapted for the mmio part of the driver, but should not have any performance implication there. MBSS tests were performed with AVM AC860 USB NIC with temporary support for 5 BSS'. Different combinations of active vifs were created and brought up. Afterwards connection and data transfer was tested for the announced BSS'.

2020-02-14mt76: mt76x02: omit beacon slot clearingMarkus Theil1-8/+0
mt76 hw does not send beacons from beacon slots, if the corresponding bitmask is set accordingly. Therefore we can omit clearing the beacon memory. Clearing uses many usb calls, if usb drivers are used. These calls unnecessarily slow down the beacon tasklet. Thanks to Stanislaw Gruzska for pointing this out.

2020-02-14mt76: use AC specific reorder timeoutMarkus Theil2-4/+14
Before this patch, mt76 handled rx traffic for all TIDs equally, when released from reorder buffer early. This patch uses an AC specific reorder timeout, in order to release partial aggregated frames for video ACs earlier. Voice ACs are currently not aggregated (thanks to Felix for this hint). For example, ath10k also uses AC specific reorder timeouts (reported by firmware in that case). Signed-off-by: Markus Theil <markus.theil@tu-ilmenau.de> Signed-off-by: Felix Fietkau <nbd@nbd.name>
