2024-02-02wifi: mac80211: adding missing drv_mgd_complete_tx() callJohannes Berg
There's a call to drv_mgd_prepare_tx() and so there should be one to drv_mgd_complete_tx(), but on this path it's not. Add it. Link: https://msgid.link/20240131164824.2f0922a514e1.I5aac89b93bcead88c374187d70cad0599d29d2c8@changeid Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2024-02-02wifi: mac80211: improve CSA/ECSA connection refusalJohannes Berg
As mentioned in the previous commit, we pretty quickly found that some APs have ECSA elements stuck in their probe response, so using that to not attempt to connect while CSA is happening we never connect to such an AP. Improve this situation by checking more carefully and ignoring the ECSA if cfg80211 has previously detected the ECSA element being stuck in the probe response. Additionally, allow connecting to an AP that's switching to a channel it's already using, unless it's using quiet mode. In this case, we may just have to adjust bandwidth later. If it's actually switching channels, it's better not to try to connect in the middle of that.

2023-12-21wifi: mac80211: Skip association timeout update after comeback rejectionJouni Malinen
It is possible for the TX status report for the (Re)Association Request frame to be delayed long enough for the AP's (Re)Association Response frame to be received and processed before it. If that were to happen for a case where the AP rejects the association with indication to come back later, the association timeout and retry state should not be modified anymore with the TX status information that would be processed after this. Updating the association timeout in such a reverse order of events could result in shortening the timeouts for the association comeback mechanism and that could result in the association failing. Track whether we have already processed association rejection with comeback time and if so, skip the timeout and retry update on any following TX status report.

2023-09-11wifi: cfg80211/mac80211: hold link BSSes when assoc fails for MLO connectionWen Gong
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.

2023-09-11wifi: cfg80211: remove wdev mutexJohannes Berg
Since we're now protecting everything with the wiphy mutex (and were really using it for almost everything before), there's no longer any real reason to have a separate wdev mutex. It may feel better, but really has no value. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2023-09-11wifi: mac80211: reduce iflist_mtxJohannes Berg
We now hold the wiphy mutex everywhere that we use or needed the iflist_mtx, so we don't need this mutex any more in mac80211. However, drivers may also iterate, and in some cases (e.g. mt76) do so from high-priority contexts. Thus, keep the mutex around but remove its usage in mac80211 apart from those driver-visible parts that are still needed. Most of this change was done automatically with spatch, with the parts that are still needed as described above reverted manually. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2023-09-11wifi: mac80211: fix SMPS status handlingJohannes Berg
The current SMPS status handling isn't per link, so we only ever change the deflink, which is obviously wrong, it's not even used for multi-link connections, but the request API actually includes the link ID. Use the new status_data changes to move the handling to the right link, this also saves parsing the frame again on the status report, instead we can now check only if it was an SMPS frame. Of course, move the worker to be a wiphy work so that we're able to cancel it safely for the link. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
