2024-10-23wifi: iwlwifi: work around -Wenum-compare-conditional warningArnd Bergmann
This is one of only three -Wenum-compare-conditional warnings we get in randconfig builds: drivers/net/wireless/intel/iwlwifi/mvm/sta.c:4331:17: error: conditional expression between different enumeration types ('enum iwl_fw_sta_type' and 'enum iwl_sta_type') [-Werror,-Wenum-compare-conditional] 4331 | u32 type = mld ? STATION_TYPE_PEER : IWL_STA_LINK; | ^ ~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~ This is a false positive since the code works as intended, but the warning is otherwise sensible, so slightly rewrite it in order to not trigger the warning.

2024-10-23wifi: mac80211: re-order assigning channel in activate linksAditya Kumar Singh
The current flow in _ieee80211_set_active_links() does not align with the operational requirements of drivers that groups multiple hardware under a single wiphy. These drivers (e.g ath12k) rely on channel assignment to determine the appropriate hardware for each link. Without this, the drivers cannot correctly establish the link interface. Currently in _ieee80211_set_active_links(), after calling drv_change_vif_links() on the driver, the state of all connected stations is updated via drv_change_sta_links(). This is followed by handling keys in the links, and finally, assigning the channel to the links. Consequently, drv_change_sta_links() prompts drivers to create the station entry at their level and within their firmware. However, since channels have not yet been assigned to links at this stage, drivers have not created the necessary link interface for establishing link stations, leading to failures in activating the links. Therefore, re-order the logic so that after drv_change_vif_links() and removing the old links, channels are assigned to newly added links. Following this, the flow proceeds to station handling.

2024-09-03wifi: iwlwifi: mvm: properly set the rates in link cmdMiri Korenblit
When a channel ctx is assigned to a link, we set the LINK_CONTEXT_MODIFY_RATES_INFO to indicate that the rate fields are now valid. But then we always take the rates of 2.4 GHz regardless of actual used band. This is because we are getting the band from bss_conf->chanctx_conf, but this is assigned only after drv_assign_vif_chanctx returns, so we take the bands of 2.4 GHz. Fix it by taking the band from the iwl_mvm_link_info::phy_ctxt instead, as this has already assigned in this point.

This shouldn't happen at all, since in station mode all MMPDUs go through the TXQ for the STA, and not this function. There may or may not be a race in mac80211 through which this might happen for some frames while a station is being added, but in that case we can also just drop the frame and pretend the STA didn't exist yet. Also, the code is simply wrong since it uses deflink, and it's not easy to fix it since the mvmvif->ap_sta pointer cannot be used without the mutex, and perhaps the right link might not even be known.

2024-08-27wifi: iwlwifi: mvm: Offload RLC/SMPS functionality to firmwareDaniel Gabay
Currently, the driver handles SMPS decisions by tracking AP capabilities, BT coexistence changes, sending necessary SMPS frames to the AP, and updating firmware with RX chain info using the RLC_CONFIG_CMD. Starting with version 3 of the RLC_CONFIG_CMD, the firmware takes over this responsibility. It now tracks SMPS, sends frames, and configures the RLC. In this patch: 1. Stop sending RLC_CONFIG_CMD when firmware supports RLC offload (version 3), as rlc.rx_chain_info is not needed by firmware, and no other field in the cmd is used. 2. Prevent the driver from forwarding any SMPS requests to mac80211, i.e., the driver should not transmit SMPS frames to the AP as firmware handles that. 3. Set NL80211_FEATURE_DYNAMIC_SMPS and NL80211_FEATURE_STATIC_SMPS conditionally based on RLC version.

2024-08-27wifi: iwlwifi: mvm: Fix a race in scan abort flowIlan Peer
When the upper layer requests to cancel an ongoing scan, a race is possible in which by the time the driver starts to handle the upper layers scan cancel flow, the FW already completed handling the scan request and the driver received the scan complete notification but still did not handle the notification. In such a case the FW will simply ignore the scan abort request coming from the driver, no notification would arrive from the FW and the entire abort flow would be considered a failure. To better handle this, check the status code returned by the FW for the scan abort command. In case the status indicates that no scan was aborted, complete the scan abort flow with success, i.e., the scan was aborted, as the flow is expected to consume the scan complete notification.
