wifi: mt76: fix race condition related to checking tx queue fill status

2023-09-30T18:03:03Z

When drv_tx calls race against local tx scheduling, the queue fill status checks can potentially race, leading to dma queue entries being overwritten. Fix this by deferring packets from drv_tx calls to the tx worker, in order to ensure that all regular queue tx comes from the same context. Reported-by: Ryder Lee Signed-off-by: Felix Fietkau

wifi: mt76: report non-binding skb tx rate when WED is active

2023-07-25T19:59:40Z

AQL relies on accurate tx rate reporting, so add this patch for non-binding skb rate when WED is enabled. Co-developed-by: Ryder Lee Signed-off-by: Ryder Lee Signed-off-by: Peter Chiu Signed-off-by: Felix Fietkau

wifi: mt76: mt7915: rework tx bytes counting when WED is active

2023-07-25T19:59:40Z

Concurrent binding/non-binding skbs could be handled anywhere which leads to mixed byte counting, so switch to use PPDU TxS reporting regardless Tx paths when WED is active.

wifi: mt76: add missing locking to protect against concurrent rx/status calls

2023-04-17T13:39:05Z

According to the documentation, ieee80211_rx_list must not run concurrently with ieee80211_tx_status (or its variants). Cc: stable@vger.kernel.org Fixes: 88046b2c9f6d ("mt76: add support for reporting tx status with skb") Reported-by: Brian Coverstone Signed-off-by: Felix Fietkau

wifi: ieee80211: correctly mark FTM frames non-bufferable

2023-04-13T14:32:02Z

The checks of whether or not a frame is bufferable were not taking into account that some action frames aren't, such as FTM. Check this, which requires some changes to the function ieee80211_is_bufferable_mmpdu() since we need the whole skb for the checks now. Reviewed-by: Ilan Peer Signed-off-by: Johannes Berg

wifi: mt76: fix rate reporting / throughput regression on mt7915 and newer

2022-10-06T05:19:04Z

mt7915 and newer need to report the rate_info that's stored in wcid->rate, since they don't fill info->status.rates.
