wifi: mac80211: split mesh fast tx cache into local/proxied/forwarded

2024-04-17T07:21:32Z

Depending on the origin of the packets (and their SA), 802.11 + mesh headers could be filled in differently. In order to properly deal with that, add a new field to the lookup key, indicating the type (local, proxied or forwarded). This can fix spurious packet drop issues that depend on the order in which nodes/hosts communicate with each other.

wifi: mac80211: check EHT/TTLM action frame length

2024-04-08T18:11:21Z

Check the EHT action frame length before accessing the action code, if it's not present then the frame cannot be valid.

wifi: mac80211: implement MLO multicast deduplication

If the vif is an MLD then it may receive multicast from different links, and should drop those frames according to the SN. Implement that. Link: https://msgid.link/20240129200456.693b77d14b44.I491846f2bea0058c14eab6422962c10bfae9b675@changeid Signed-off-by: Johannes Berg

wifi: mac80211: process and save negotiated TID to Link mapping request

2024-01-26T08:39:48Z

An MLD may send TID-to-Link mapping request frame to negotiate TID to link mapping with a peer MLD. Support handling negotiated TID-to-Link mapping request frame by parsing the frame, asking the driver whether it supports the received mapping or not, and sending a TID-to-Link mapping response to the AP MLD. Theoretically, links that became inactive due to the received TID-to-Link mapping request, can be selected to be activated but this would require tearing down the negotiated TID-to-Link mapping, which is still not supported.

wifi: mac80211: allow 64-bit radiotap timestamps

2023-12-21T19:35:15Z

When reporting the radiotap timestamp, the mactime field is usually unused, we take the data from the device_timestamp. However, there can be cases where the radiotap timestamp is better reported as a 64-bit value, so since the mactime is free, add a flag to support using the mactime as a 64-bit radiotap timestamp.
