2023-10-23wifi: mac80211: rename struct cfg80211_rx_assoc_resp to ↵Kalle Valo1-1/+1
cfg80211_rx_assoc_resp_data make htmldocs warns: Documentation/driver-api/80211/cfg80211:48: ./include/net/cfg80211.h:7290: WARNING: Duplicate C declaration, also defined at cfg80211:7251. Declaration is '.. c:function:: void cfg80211_rx_assoc_resp (struct net_device *dev, struct cfg80211_rx_assoc_resp *data)'. This is because there's a function named cfg80211_rx_assoc_resp() and a struct named cfg80211_rx_assoc_resp, see previous patch for more info. To workaround this rename the struct to cfg80211_rx_assoc_resp_data. The parameter for the function is named 'data' anyway so the naming here is consistent. Compile tested only.

2023-10-23wifi: mac80211: add link id to mgd_prepare_tx()Miri Korenblit1-1/+8
As we are moving to MLO and links terms, also the airtime protection will be done for a link rather than for a vif. Thus, some drivers will need to know for which link to protect airtime. Add link id as a parameter to the mgd_prepare_tx() callback.

2023-10-23wifi: mac80211: Check if we had first beacon with relevant linksMiri Korenblit1-3/+14
If there is a disassoc before the fisrt beacon we need to protect a session for the deauth frame. Currently we are checking if we had a beacon in the default link, which is wrong in a MLO connection and link id != 0. Fix this by checking all the active links, if none had a beacon then protect a session. If at least one link had a beacon there is no need for session protection.

2023-10-23wifi: mac80211: cleanup auth_data only if association continuesBenjamin Berg1-4/+13
If the association command fails then the authentication is still valid and it makes sense to keep it alive. Otherwise, we would currently get into an inconsistent state because mac80211 on the one hand is disconnected but on the other hand the state is not entirely cleared and a new authentication could not continue.

2023-09-11wifi: mac80211: take MBSSID/EHT data also from probe respJohannes Berg1-10/+15
The code that sets up the assoc link will currently take the BSS element data from the beacon only. This is correct for some of the data, notably the timing and the "have_beacon", but all the data about MBSSID and EHT really doesn't need to be taken from there, and if the EHT puncturing is misconfigured on the AP but we didn't receive a beacon yet, this causes us to connect but immediately disconnect upon receiving the first beacon, rather than connecting without EHT in the first place. Change the code to take MBSSID and EHT data also from the probe response, for a better picture of what the BSS capabilities are and to avoid that EHT puncturing problem.

2023-09-11wifi: cfg80211/mac80211: hold link BSSes when assoc fails for MLO connectionWen Gong1-5/+6
When connect to MLO AP with more than one link, and the assoc response of AP is not success, then cfg80211_unhold_bss() is not called for all the links' cfg80211_bss except the primary link which means the link used by the latest successful association request. Thus the hold value of the cfg80211_bss is not reset to 0 after the assoc fail, and then the __cfg80211_unlink_bss() will not be called for the cfg80211_bss by __cfg80211_bss_expire(). Then the AP always looks exist even the AP is shutdown or reconfigured to another type, then it will lead error while connecting it again. The detail info are as below. When connect with muti-links AP, cfg80211_hold_bss() is called by cfg80211_mlme_assoc() for each cfg80211_bss of all the links. When assoc response from AP is not success(such as status_code==1), the ieee80211_link_data of non-primary link(sdata->link[link_id]) is NULL because ieee80211_assoc_success()->ieee80211_vif_update_links() is not called for the links. Then struct cfg80211_rx_assoc_resp resp in cfg80211_rx_assoc_resp() and struct cfg80211_connect_resp_params cr in __cfg80211_connect_result() will only have the data of the primary link, and finally function cfg80211_connect_result_release_bsses() only call cfg80211_unhold_bss() for the primary link. Then cfg80211_bss of the other links will never free because its hold is always > 0 now. Hence assign value for the bss and status from assoc_data since it is valid for this case. Also assign value of addr from assoc_data when the link is NULL because the addrs of assoc_data and link both represent the local link addr and they are same value for success connection.

2023-06-14wifi: mac80211: Add getter functions for vif MLD stateIlan Peer1-21/+22
As a preparation to support disabled/dormant links, add the following function: - ieee80211_vif_usable_links(): returns the bitmap of the links that can be activated. Use this function in all the places that the bitmap of the usable links is needed. - ieee80211_vif_is_mld(): returns true iff the vif is an MLD. Use this function in all the places where an indication that the connection is a MLD is needed.

2023-06-14wifi: mac80211: fix CSA processing while scanningBenjamin Berg1-3/+4
The channel switch parsing code would simply return if a scan is in-progress. Supposedly, this was because channel switch announcements from other APs should be ignored. For the beacon case, the function is already only called if we are associated with the sender. For the action frame cases, add the appropriate check whether the frame is coming from the AP we are associated with. Finally, drop the scanning check from ieee80211_sta_process_chanswitch.

2023-06-14wifi: mac80211: add helpers to access sband iftype dataJohannes Berg1-20/+10
There's quite a bit of code accessing sband iftype data (HE, HE 6 GHz, EHT) and we always need to remember to use the ieee80211_vif_type_p2p() helper. Add new helpers to directly get it from the sband/vif rather than having to call ieee80211_vif_type_p2p(). Convert most code with the following spatch: @@ expression vif, sband; @@ -ieee80211_get_he_iftype_cap(sband, ieee80211_vif_type_p2p(vif)) +ieee80211_get_he_iftype_cap_vif(sband, vif) @@ expression vif, sband; @@ -ieee80211_get_eht_iftype_cap(sband, ieee80211_vif_type_p2p(vif)) +ieee80211_get_eht_iftype_cap_vif(sband, vif) @@ expression vif, sband; @@ -ieee80211_get_he_6ghz_capa(sband, ieee80211_vif_type_p2p(vif)) +ieee80211_get_he_6ghz_capa_vif(sband, vif) Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Gregory Greenman <gregory.greenman@intel.com> Link: https://lore.kernel.org/r/20230604120651.db099f49e764.Ie892966c49e22c7b7ee1073bc684f142debfdc84@changeid Signed-off-by: Johannes Berg <johannes.berg@intel.com>
