wifi: mac80211: use wiphy work for SMPS

2023-06-07T17:53:22+00:00

SMPS requests are per link, and currently there's a potential deadlock with canceling. Use the new wiphy work to handle SMPS instead, so that the cancel cannot deadlock. Signed-off-by: Johannes Berg

wifi: mac80211: Fix iTXQ AMPDU fragmentation handling

2023-01-10T12:24:17+00:00

mac80211 must not enable aggregation wile transmitting a fragmented MPDU. Enforce that for mac80211 internal TX queues (iTXQs).

wifi: mac80211: keep A-MSDU data in sta and per-link

2022-09-06T08:17:08+00:00

The A-MSDU data needs to be stored per-link and aggregated into a single value for the station. Add a new struct ieee_80211_sta_aggregates in order to store this data and a new function ieee80211_sta_recalc_aggregates to update the current data for the STA. Note that in the non MLO case the pointer in ieee80211_sta will directly reference the data in deflink.agg, which means that recalculation may be skipped in that case.

wifi: mac80211: make smps_mode per-link

2022-09-06T08:11:44+00:00

The SMPS power save mode needs to be per-link rather than being shared for all links. As such, move it into struct ieee80211_link_sta. Signed-off-by: Benjamin Berg Signed-off-by: Johannes Berg

wifi: mac80211: move ieee80211_request_smps_mgd_work

2022-07-15T09:43:15+00:00

This function can be static. Signed-off-by: Johannes Berg

wifi: mac80211: RCU-ify link/link_conf pointers

2022-07-15T09:43:14+00:00

Since links can be added and removed dynamically, we need to somehow protect the sdata->link[] and vif->link_conf[] array pointers from disappearing when accessing them without locks. RCU-ify the pointers to achieve this, which requires quite a bit of rework. Signed-off-by: Johannes Berg

wifi: mac80211: RCU-ify link STA pointers

2022-06-20T10:57:08+00:00

We need to be able to access these in a race-free way under traffic while adding/removing them, so RCU-ify the pointers. This requires passing a link_sta to a lot of functions so we don't have to do the RCU handling everywhere. Signed-off-by: Johannes Berg

wifi: mac80211: make some SMPS code MLD-aware

2022-06-20T10:55:30+00:00

Start making some SMPS related code MLD-aware. This isn't really done yet, but again cuts down our 'deflink' reliance. Signed-off-by: Johannes Berg

wifi: mac80211: HT: make ieee80211_ht_cap_ie_to_sta_ht_cap() MLO-aware

2022-06-20T10:55:29+00:00

Update ieee80211_ht_cap_ie_to_sta_ht_cap() to handle per-link data. Signed-off-by: Johannes Berg

wifi: mac80211: reorg some iface data structs for MLD

2022-06-20T10:55:06+00:00

Start reorganizing interface related data structures toward MLD. The most complex part here is for the keys, since we have to split the various kinds of GTKs off to the link but still need to use (for WEP) the other keys as a fallback even for multicast frames. Signed-off-by: Johannes Berg
