wifi: mac80211: fix min center freq offset tracing

2023-05-24T16:32:46+00:00

[ Upstream commit 248e4776514bf70236e6b1a54c65aa5324c8b1eb ] We need to set the correct trace variable, otherwise we're overwriting something else instead and the right one that we print later is not initialized.

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: move ps setting to vif config

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

This really shouldn't be in a per-link config, we don't want to let anyone control it that way (if anything, link powersave could be forced through APIs to activate/deactivate a link), and we don't support powersave in software with devices that can do MLO. 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.
