2020-03-17mt76: mt7615: fix monitor injection of beacon framesFelix Fietkau3-5/+5
When injecting beacon frames via monitor interface, they must not be sent to the beacon hardware queue, because they don't follow normal hardware beacon tx rules.

2020-03-17mt76: mt76u: rely only on data buffer for usb control messaggesLorenzo Bianconi2-5/+4
Starting from commit 'a6bfb6d13f33 ("mt76: usb: use max packet length for m76u_copy")' reg_val does not share memory with usb data buffer. On non-coherent devices this approach can corrupt data pointer since data and reg_val share the same cache-line, resulting in the following crash: [ 371.544901] CPU 0 Unable to handle kernel paging request at virtual address 00000000, epc == 8042fbb0 [ 371.558521] CPU: 0 PID: 11 Comm: kworker/u2:2 Not tainted 4.14.160 #0 [ 371.565204] Workqueue: mt76u mt76u_deinit [mt76_usb] [ 371.570331] task: 83823ac0 task.stack: 8386c000 [ 371.575004] $ 0 : 00000000 80590000 00000000 00000000 [ 371.580407] $ 4 : 82edaad0 00000002 83823ac0 fffffff8 [ 371.585810] $ 8 : fffffffd 0000fc00 8052da00 00000000 [ 371.591212] $12 : 000b2285 ae53a1a9 00108845 89da44c4 [ 371.596615] $16 : 82edaad0 82ed9d20 00001798 832edf00 [ 371.602019] $20 : 00000000 8386dda8 80530000 fffffffe [ 371.607421] $24 : 8051d040 76274d1b [ 371.612824] $28 : 8386c000 8386dd88 82edaad4 830d4d50 [ 371.618228] Hi : 000000f7 [ 371.621203] Lo : 33333371 [ 371.624196] epc : 8042fbb0 __mutex_lock.isra.2+0x134/0x378 [ 371.630043] ra : 830d4d50 mt76u_deinit+0x418/0xa6c [mt76_usb] [ 371.636237] Status: 1000fc03KERNEL EXL IE [ 371.640557] Cause : 0080000c (ExcCode 03) [ 371.644696] BadVA : 00000000 [ 371.647671] PrId : 00019374 (MIPS 24Kc) [ 371.726123] usbcore nls_base usb_common [ 371.730180] Process kworker/u2:2 (pid: 11, threadinfo=8386c000, task=83823ac0, tls=00000000) [ 371.738884] Stack : 833d009c 83210b4c 82ed8bc0 8386ddac 000001ff 8008ac50 8386ddac 83b74b00 [ 371.747519] 82edaad4 00000000 83b74b48 83210c38 82edaad0 82ed9d20 00001798 832edf00 [ 371.756157] 00000000 00000000 80530000 fffffffe 80530000 830d4d50 00000040 8389d850 [ 371.764794] 8052d9d8 8389d850 8386de30 82ed9d20 8386de5f 831c27bc 833d48ec 8052d9d8 [ 371.773431] 83823ac0 83823af0 82edab00 82ed9d20 8386de5f 831c5c30 00000000 8052d9a8 [ 371.782069] ...

2020-02-14mt76: mt7615: rework rx phy index handlingFelix Fietkau4-50/+75
Overwriting the RMAC_CHFREQ register is not reliable enough, as the firmware could potentially write it again. Since there is no PHY index indication in the rx info, we need to use another way: If both PHYs are using different channels, find the PHY where chfreq matches the register value. The only corner case remaining is when both PHYs are using the same channel. In that case, the per-packet noise value on the primary PHY will have information belonging to the chains of the secondary PHY from the previous received packet of that PHY. The secondary PHY will set noise to 0 for extra chains. Signed-off-by: Felix Fietkau <nbd@nbd.name>
