wifi: mac80211: pass frame type to element parsing

2025-11-10T09:39:02Z

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

2025-06-24T13:19:26Z

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

2025-04-23T13:21:32Z

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.

treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12Z

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

wifi: mac80211: ibss: mark IBSS left before leaving

2025-01-13T14:34:10Z

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

2025-01-13T14:34:10Z

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.

wifi: mac80211: call rate_control_rate_update() for link STA

2024-10-23T14:43:27Z

In order to update the right link information, call the update rate_control_rate_update() with the right link_sta, and then pass that through to the driver's sta_rc_update() method. The software rate control still doesn't support it, but that'll be skipped by not having a rate control ref. Since it now operates on a link sta, rename the driver method.

wifi: mac80211: allow rate_control_rate_init() for links

2024-10-23T14:43:23Z

Andrei previously fixed an issue in the client where the NSS for links other than the primary/assoc/deflink isn't set. The same issue appears to exist on the AP side, because there's only a call to rate_control_rate_init() for the deflink, and not any other links. Rework the code a bit to do rate_control_rate_init() for links, even if it really doesn't work with software rate control yet, it does other things as well. Also add rate_control_rate_init_all_links() to actually do it properly when moving to ASSOC state in cfg80211. Change the explicit call to ieee80211_sta_init_nss() to instead be rate_control_rate_init() now in the client code, but also add a call to rate_control_rate_init() when a link is added in AP mode and the STA is already associated. This should fix the NSS initialization issue, and perhaps pave the way for actual software rate scaling a bit, in case anyone cares in the future, but that of course needs a lot more than just the init call. We still need to fix the rate control _update_ as well, and the sta_rc_update() driver method especially, but that will be in a different patch.
