wifi: mac80211: don't require cipher and keylen in gtk rekey

2025-07-22T08:43:19+00:00

ieee80211_add_gtk_rekey receives a keyconf as an argument, and the cipher and keylen are taken from there to the new allocated key. But in rekey, both the cipher and the keylen should be the same as of the old key, so let ieee80211_add_gtk_rekey find those, so drivers won't have to fill it in.

wifi: rtw89: wow: Add Basic Rate IE to probe request in scheduled scan mode

2025-07-18T06:36:56+00:00

In scheduled scan mode, the current probe request only includes the SSID IE, but omits the Basic Rate IE. Some APs do not respond to such incomplete probe requests, causing net-detect failures. To improve interoperability and ensure APs respond correctly, add the Basic Rate IE to the probe request in driver.

wifi: rtw89: Lower the timeout in rtw89_fwdl_check_path_ready_ax() for USB

2025-07-18T06:22:35+00:00

When the chip is not powered on correctly (like during driver development) rtw89_fwdl_check_path_ready_ax() can fail. read_poll_timeout_atomic() with a delay of 1 µs and a timeout of 400000 µs can take 50 seconds with USB because of the time it takes to send a USB control message. The firmware upload is tried 5 times, so in total it takes 250 seconds. Lower the timeout to 3200 for USB in order to reduce the time rtw89_fwdl_check_path_ready_ax() takes from 50 seconds to less than 1 second.

wifi: rtw89: Lower the timeout in rtw89_fw_read_c2h_reg() for USB

2025-07-18T06:21:29+00:00

This read_poll_timeout_atomic() with a delay of 1 µs and a timeout of 1000000 µs can take ~250 seconds in the worst case because sending a USB control message takes ~250 µs. Lower the timeout to 4000 for USB in order to reduce the maximum polling time to ~1 second. This problem was observed with RTL8851BU while suspending to RAM with WOWLAN enabled. The computer sat for 4 minutes with a black screen before suspending.

wifi: rtw89: check path range before using in rtw89_fw_h2c_rf_ps_info()

2025-07-18T06:03:34+00:00

The variable 'path' from rtw89_phy_get_syn_sel() as index of array could be 3, but array size is 2. Fortunately, current chip->rf_path_num is smaller or equal to 2, so it is safe. To prevent mistakes in the future, add a checking and avoid Coverity warnings.

wifi: rtw89: purge obsoleted scan events with software sequence number

2025-07-18T06:02:03+00:00

The queued and obsoleted scan events can be wrongly treated as events of new scan request, causing unexpected scan result. Attach a software sequence number to scan request and its corresponding events. When a new scan request is acknowledged by firmware, purge the scan events if its sequence number is not belong to current request.

When the 'Disabled Subchannel Bitmap' within the EHT Operation element is changed, mac80211 parse and pass it to the driver. The driver is then updated with this puncturing bitmap to optimize bandwidth usage and prevent interference from degrading performance across the entire channel.
