wifi: mac80211: export ieee80211_calculate_rx_timestamp

2026-04-07T13:36:02+00:00

The function is quite useful when handling beacon timestamps. Export it so that it can be used by mac80211_hwsim and others.

wifi: mac80211: don't consider the sband when processing capabilities

2026-03-24T15:32:16+00:00

In NAN, we have one set of (HT, VHT, HE) capabilities for all bands, which means that we will need to process those capabilities without a given sband. To prepare for that, remove the sband argument from ieee80211_ht_cap_ie_to_sta_ht_cap and ieee80211_he_cap_ie_to_sta_he_cap and pass our own capabilities instead. For ieee80211_vht_cap_ie_to_sta_vht_cap, make the sband argument optional, since it is also used to check if there is at least one channel that supports 80 MHz. (Note that this check doesn't make much sense, but this can be handled in a different patch.)

wifi: move action code from per-type frame structs

2026-03-06T09:36:26+00:00

The action code actually serves to identify the type of action frame, so it really isn't part of the per-type structure. Pull it out and have it in the general action frame format. In theory, whether or not the action code is present in this way is up to each category, but all categories that are defined right now all have that value. While at it, and since this change requires changing all users, remove the 'u' and make it an anonymous union in this case, so that all code using this changes. Change IEEE80211_MIN_ACTION_SIZE to take an argument which says how much of the frame is needed, e.g. category, action_code or the specific frame type that's defined in the union. Again this also ensures that all code is updated. In some cases, fix bugs where the SKB length was checked after having accessed beyond the checked length, in particular in FTM code, e.g. ieee80211_is_ftm().

wifi: mac80211: pass frame type to element parsing

2025-11-10T09:39:02+00:00

This will be needed for UHR operation parsing, and we already pass whether or not the frame is an action frame, replace that by the full type. Note this fixes a few cases where 'false' was erroneously passed (mesh and TDLS) and removes ieee802_11_parse_elems_crc() as it's unused.

wifi: mac80211: add support towards MLO handling of station statistics

2025-06-24T13:19:26+00:00

Currently, in supporting API's to fill sinfo structure from sta structure, is mapped to fill the fields from sta->deflink. However, for multi-link (ML) station, sinfo structure should be filled from corresponding link_id. Therefore, add link_id as an additional argument in supporting API's for filling sinfo structure correctly. Link_id is set to -1 for non-ML station and corresponding link_id for ML stations. In supporting API's for filling sinfo structure, check for link_id, if link_id < 0, fill the sinfo structure from sta->deflink, otherwise fill from sta->link[link_id]. Current, changes are done at the deflink level i.e, pass -1 as link_id. Actual link_id will be added in subsequent patches to support station statistics for MLO.

wifi: cfg80211/mac80211: remove more 5/10 MHz code

2025-04-23T13:21:32+00:00

We still have ieee80211_chandef_rate_flags() and all that, but all the users seem pretty much broken (deflink, etc.) Remove all the code. It's been two years since last anyone even vaguely entertained the notion of looking at this and fixing it.

wifi: mac80211: ibss: mark IBSS left before leaving

2025-01-13T14:34:10+00:00

Mark that we left the IBSS before actually leaving (which requires calling the driver). Otherwise, it's possible to have the driver do some work flushing etc. while leaving, and then get into the work trying to join again while all data is being destroyed.

wifi: mac80211: ibss: stop transmit when merging IBSS

2025-01-13T14:34:10+00:00

We disable the carrier, but that doesn't immediately take effect, and as such a concurrent transmit can go into the driver while drv_leave_ibss() is happening and confuse it. Synchronize to avoid that.
