wifi: mt76: handle failure of vzalloc in mt7615_coredump_work

2023-05-11T14:11:16Z

[ Upstream commit 9e47dd9f64a47ae00ca0123017584c37209ee900 ] vzalloc may fails, dump might be null and will cause illegal address access later.

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

2023-05-11T14:10:51Z

commit 5b8ccdfb943f6a03c676d2ea816dd38c149e920b upstream. According to the documentation, ieee80211_rx_list must not run concurrently with ieee80211_tx_status (or its variants).

wifi: mt76: ignore key disable commands

2023-04-13T15:02:55Z

commit e6db67fa871dee37d22701daba806bfcd4d9df49 upstream. This helps avoid cleartext leakage of already queued or powersave buffered packets, when a reassoc triggers the key deletion.

wifi: mt76: fix rx checksum offload on mt7615/mt7915/mt7921

2022-10-11T08:41:20Z

Checking the relevant rxd bits for the checksum information only indicates if the checksum verification was performed by the hardware and doesn't show actual checksum errors. Checksum errors are indicated in the info field of the DMA descriptor. Fix packets erroneously marked as CHECKSUM_UNNECESSARY by checking the extra bits as well. Those bits are only passed to the driver for MMIO devices at the moment, so limit checksum offload to those.

wifi: mt76: fix receiving LLC packets on mt7615/mt7915

2022-10-11T08:41:20Z

When 802.3 decap offload is enabled, the hardware indicates header translation failure, whenever either the LLC-SNAP header was not found, or a VLAN header with an unregcognized tag is present. In that case, the hardware inserts a 2-byte length fields after the MAC addresses. For VLAN packets, this tag needs to be removed. However, for 802.3 LLC packets, the length bytes should be preserved, since there is no separate ethertype field in the data. This fixes an issue where the length field was omitted for LLC frames, causing them to be malformed after hardware decap.
