wifi: mac80211: isolate driver from inactive links

2022-09-06T08:12:44+00:00

In order to let the driver select active links and properly make multi-link connections, as a first step isolate the driver from inactive links, and set the active links to be only the association link for client-side interfaces. For AP side nothing changes since APs always have to have all their links active. To simplify things, update the for_each_sta_active_link() API to include the appropriate vif pointer. This also implies not allocating a chanctx for an inactive link, which requires a few more changes. Since we now no longer try to program multiple links to the driver, remove the check in the MLME code. Signed-off-by: Johannes Berg

wifi: mac80211: remove link_id parameter from link_info_changed()

2022-07-15T09:43:20+00:00

Since struct ieee80211_bss_conf already contains link_id, passing link_id is not necessary. Signed-off-by: Gregory Greenman Signed-off-by: Johannes Berg

wifi: mac80211: replace link_id with link_conf in switch/(un)assign_vif_chanctx()

2022-07-15T09:43:20+00:00

Since mac80211 already has a protected pointer to link_conf, pass it to the driver to avoid additional RCU locking. Signed-off-by: Gregory Greenman Signed-off-by: Johannes Berg

wifi: mac80211: replace link_id with link_conf in start/stop_ap()

2022-07-15T09:43:17+00:00

When calling start/stop_ap(), mac80211 already has a protected link_conf pointer. Pass it to the driver, so it shouldn't handle RCU protection. Signed-off-by: Gregory Greenman Signed-off-by: Johannes Berg

wifi: mac80211: change QoS settings API to take link into account

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

Take the link into account in the QoS settings (EDCA parameters) APIs. 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: pass the link id in start/stop ap

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

In start_ap and stop_ap mac80211 callbacks pass the link_id to the drivers. Signed-off-by: Shaul Triebitz Signed-off-by: Johannes Berg

wifi: mac80211: add sta link addition/removal

2022-06-20T10:56:06+00:00

Add the necessary infrastructure, including a new driver method, to add/remove links to/from a station. To do this, refactor the link alloc/free a bit, splitting that so we can do it without linking them, to handle failures better. Note that a station entry must be created representing an MLD or a non-MLD STA, it cannot change between the two. When representing an MLD, the 'deflink' is used for the first link, which might be removed later, in which case the memory isn't reused. Signed-off-by: Johannes Berg

wifi: mac80211: add vif link addition/removal

2022-06-20T10:55:59+00:00

Add the necessary infrastructure, including a new driver method, to add/remove links to/from an interface. Also add the missing link address to bss_conf (which we use as link_conf too), and fill it, in station mode for now just randomly, in AP mode we get the address from cfg80211 since the link must be created with an address first.

wifi: mac80211: make channel context code MLO-aware

2022-06-20T10:55:15+00:00

Make the channel context code MLO aware, along with some functions that it uses, so that the chan.c file is now MLD-clean and no longer uses deflink/bss_conf/etc. Signed-off-by: Johannes Berg
