wifi: mt76: mt7925: replace chan config with extend txpower config for clc

2024-09-06T12:23:08Z

Since MT792x_CLC_CHAN is currently not in use, we have added an extension for setting txpower to replace it. Signed-off-by: Ming Yen Hsieh Link: https://patch.msgid.link/20240819015334.14580-2-mingyen.hsieh@mediatek.com Signed-off-by: Felix Fietkau

wifi: mt76: mt7925: fix a potential array-index-out-of-bounds issue for clc

2024-09-06T12:23:08Z

Due to the lack of checks on the clc array, if the firmware supports more clc configuration, it will cause illegal memory access.

wifi: mt76: mt7615: check devm_kasprintf() returned value

2024-09-06T12:23:07Z

devm_kasprintf() can return a NULL pointer on failure but this returned value is not checked. Fix this lack and check the returned value. Found by code review.

wifi: mt76: mt7925: convert comma to semicolon

2024-09-06T12:23:07Z

Replace comma between expressions with semicolons. Using a ',' in place of a ';' can have unintended side effects. Although that is not the case here, it is seems best to use ';' unless ',' is intended. Found by inspection. No functional change intended. Compile tested only.

wifi: mt76: mt7925: fix a potential association failure upon resuming

2024-09-06T12:23:07Z

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 warnings

2024-09-06T12:23:07Z

-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.
