| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In multi-channel scenarios, the granted channel must be aborted before suspending. Otherwise, the firmware will be put into a wrong state, resulting in an association failure after resuming. With this patch, the granted channel will be aborted before suspending if necessary.

| * wifi: mt76: Avoid multiple -Wflex-array-member-not-at-end warningsGustavo A. R. Silva2024-09-062-14/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | -Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally. So, in order to avoid ending up with a flexible-array member in the middle of multiple other structs, we use the `struct_group_tagged()` helper to create a new tagged `struct mt76_connac2_mcu_rxd_hdr`. This structure groups together all the members of the flexible `struct mt76_connac2_mcu_rxd` except the flexible array. As a result, the array is effectively separated from the rest of the members without modifying the memory layout of the flexible structure. We then change the type of the middle struct members currently causing trouble from `struct mt76_connac2_mcu_rxd` to `struct mt76_connac2_mcu_rxd_hdr`. We also want to ensure that when new members need to be added to the flexible structure, they are always included within the newly created tagged struct. For this, we use `static_assert()`. This ensures that the memory layout for both the flexible structure and the new tagged struct is the same after any changes. This approach avoids having to implement `struct mt76_connac2_mcu_rxd_hdr` as a completely separate structure, thus preventing having to maintain two independent but basically identical structures, closing the door to potential bugs in the future. So, with these changes, fix the following warnings: drivers/net/wireless/mediatek/mt76/mt7915/mcu.h:32:37: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/net/wireless/mediatek/mt76/mt7915/mcu.h:40:37: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/net/wireless/mediatek/mt76/mt7915/mcu.h:49:37: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/net/wireless/mediatek/mt76/mt7915/mcu.h:58:37: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Signed-off-by: Gustavo A.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to IEEE P802.11be/D6.0 Table 9-417n, beamformee SS field stands for the maximum number of spatial streams that the STA can receive in an EHT sounding NDP minus 1, and the minimum value of this field is 3. This value indicates the decoding capability of a beamformee, which is independent of current antenna settings. Correct the value for mt7996 and mt7992 chipsets based on their HW capability.

* | wifi: mac80211: handle ieee80211_radar_detected() for MLOAditya Kumar Singh2024-09-064-5/+5
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently DFS works under assumption there could be only one channel context in the hardware. Hence, drivers just calls the function ieee80211_radar_detected() passing the hardware structure. However, with MLO, this obviously will not work since number of channel contexts will be more than one and hence drivers would need to pass the channel information as well on which the radar is detected. Also, when radar is detected in one of the links, other link's CAC should not be cancelled. Hence, in order to support DFS with MLO, do the following changes - * Add channel context conf pointer as an argument to the function ieee80211_radar_detected(). During MLO, drivers would have to pass on which channel context conf radar is detected. Otherwise, drivers could just pass NULL. * ieee80211_radar_detected() will iterate over all channel contexts present and * if channel context conf is passed, only mark that as radar detected * if NULL is passed, then mark all channel contexts as radar detected * Then as usual, schedule the radar detected work. * In the worker, go over all the contexts again and for all such context which is marked with radar detected, cancel the ongoing CAC by calling ieee80211_dfs_cac_cancel() and then notify cfg80211 via cfg80211_radar_event(). * To cancel the CAC, pass the channel context as well where radar is detected to ieee80211_dfs_cac_cancel(). This ensures that CAC is canceled only on the links using the provided context, leaving other links unaffected. This would also help in scenarios where there is split phy 5 GHz radio, which is capable of DFS channels in both lower and upper band. In this case, simultaneous radars can be detected.
