2025-06-05wifi: cfg80211/mac80211: correctly parse S1G beacon optional elementsLachlan Hodges1-5/+2
S1G beacons are not traditional beacons but a type of extension frame. Extension frames contain the frame control and duration fields, followed by zero or more optional fields before the frame body. These optional fields are distinct from the variable length elements. The presence of optional fields is indicated in the frame control field. To correctly locate the elements offset, the frame control must be parsed to identify which optional fields are present. Currently, mac80211 parses S1G beacons based on fixed assumptions about the frame layout, without inspecting the frame control field. This can result in incorrect offsets to the "variable" portion of the frame. Properly parse S1G beacon frames by using the field lengths defined in IEEE 802.11-2024, section 9.3.4.3, ensuring that the elements offset is calculated accurately.

2025-02-11wifi: mac80211: rework the Tx of the deauth in ieee80211_set_disassoc()Emmanuel Grumbach1-32/+36
When we disassociate we may need to send a deauth frame. Regardless of this decision, we need to flush the queues to drop all the packets on the Tx queues. The flow looks like this: 1) Flush packets waiting on the queues (drop=true) 2) Prepare Tx to send the deauth 3) Build the deauth header 4) send the deauth 5) Flush the deauth packet (drop=false) 6) Complete_tx Step 3 and 4 are done in ieee80211_send_deauth_disassoc() and that function must be called even if we decide not to send the deauth frame because we need step 3 for cfg80211. This means that if we want to send the deauth frame, we need all the steps, but if we don't want to send the deauth frame we still want step 1 and 3. Change the code to do that. Also, prevent sending the deauth frame if we are in the middle of a CSA with mode=1 in which case we won't be able to send the frame anyway. This caused issues in iwlwifi at step 5 since the firmware wouldn't send the frame and we'd be stuck flushing with drop=false. Implement this in ieee80211_set_disassoc() which has many callers.

At the beginning of it, the pointer to ifmgd::auth_data memory is copied to a local variable. If iface_work is queued again during the execution of the current one, and then the driver is flushing the wiphy_works (for its needs), ieee80211_destroy_auth_data will run again and free auth_data. Then when the execution of the original worker continues, the previously copied pointer will be freed, causing a kernel bug: kernel BUG at mm/slub.c:553! (double free) Same for association timeout (just with ieee80211_destroy_assoc_data and ifmgd::assoc_data) Fix this by NULLifying auth/assoc data right after we copied the pointer to it. That way, even in the scenario above, the code will not handle the same timeout twice.

2025-01-13wifi: mac80211: Support dynamic link addition and removalIlan Peer1-1/+756
Add support for adding and removing station links: - Adding links is done asynchronously, i.e., first an ML reconfiguration action frame is sent to the AP requesting to add links, and only when the AP replies, links which were added successfully by the AP are added locally. - Removing links is done synchronously, i.e., the links are removed before sending the ML reconfiguration action frame to the AP (to avoid using this links after the AP MLD removed them but before the station got the ML reconfiguration response). In case the AP replies with a status indicating that a link removal was not successful, disconnect (as this should not happen an is an indication that something might be wrong on the AP MLD).

2025-01-13wifi: mac80211: change disassoc sequence a bitMiri Korenblit1-2/+22
Currently, the sequence goes like this (among others): 1. flush all stations (including the AP ones) -> this will tell the drivers to remove the stations 2. notify the driver the vif is not associated. Which means that in between 1 and 2, the state is that the vif is associated, but there is no AP station, which makes no sense, and may be problematic for some drivers (for example iwlwifi) Change the sequence to: 1. flush the TDLS stations 2. move the AP station to IEEE80211_STA_NONE 3. notify the driver about the vif being unassociated 4. flush the AP station In order to not break other drivers, add a vif flag to indicate whether the driver wants to new sequence or not. If the flag is not set, then things will be done in the old sequence.

2024-12-03wifi: mac80211: fix a queue stall in certain cases of CSAEmmanuel Grumbach1-2/+0
If we got an unprotected action frame with CSA and then we heard the beacon with the CSA IE, we'll block the queues with the CSA reason twice. Since this reason is refcounted, we won't wake up the queues since we wake them up only once and the ref count will never reach 0. This led to blocked queues that prevented any activity (even disconnection wouldn't reset the queue state and the only way to recover would be to reload the kernel module. Fix this by not refcounting the CSA reason. It becomes now pointless to maintain the csa_blocked_queues state. Remove it.

2024-10-23wifi: mac80211: allow rate_control_rate_init() for linksJohannes Berg1-1/+1
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.
