I've suddenly realized wpa_supplicant is spamming my system logs with these messages: Sep 02 08:07:17 elite wpa_supplicant[3054]: wlp1s0: CTRL-EVENT-SIGNAL-CHANGE above=1 signal=-64 noise=9999 txrate=648500 Sep 02 08:07:20 elite wpa_supplicant[3054]: wlp1s0: CTRL-EVENT-SIGNAL-CHANGE above=1 signal=-58 noise=9999 txrate=648500 Sep 02 08:07:23 elite wpa_supplicant[3054]: wlp1s0: CTRL-EVENT-SIGNAL-CHANGE above=1 signal=-58 noise=9999 txrate=648500 Sep 02 08:07:26 elite wpa_supplicant[3054]: wlp1s0: CTRL-EVENT-SIGNAL-CHANGE above=1 signal=-64 noise=9999 txrate=648500 Sep 02 08:07:29 elite wpa_supplicant[3054]: wlp1s0: CTRL-EVENT-SIGNAL-CHANGE above=1 signal=-64 noise=9999 txrate=432300 Sep 02 08:07:32 elite wpa_supplicant[3054]: wlp1s0: CTRL-EVENT-SIGNAL-CHANGE above=1 signal=-63 noise=9999 txrate=432300 Sep 02 08:07:35 elite wpa_supplicant[3054]: wlp1s0: CTRL-EVENT-SIGNAL-CHANGE above=1 signal=-63 noise=9999 txrate=576400 Sep 02 08:07:38 elite wpa_supplicant[3054]: wlp1s0: CTRL-EVENT-SIGNAL-CHANGE above=1 signal=-64 noise=9999 txrate=576400 Sep 02 08:07:41 elite wpa_supplicant[3054]: wlp1s0: CTRL-EVENT-SIGNAL-CHANGE above=1 signal=-64 noise=9999 txrate=576400 Sep 02 08:07:44 elite wpa_supplicant[3054]: wlp1s0: CTRL-EVENT-SIGNAL-CHANGE above=1 signal=-63 noise=9999 txrate=576400 I want this to stop. My WiFi works perfectly but these seemingly debug messages drive me insane and generate over 2GB of disk writes daily. For the past three days: journalctl | grep CTRL-EVENT-SIGNAL-CHANGE | wc -l 24500 Components used: NetworkManager-1.46.2-1.fc40.x86_64 wpa_supplicant-2.11-3.fc40.x86_64 kernel-6.10.7-200.fc40.x86_64 I posted a solution here but I hate it: https://unix.stackexchange.com/questions/782886/how-to-stop-ctrl-event-signal-change-spam-in-system-logs
This was first raised five years ago: https://groups.google.com/g/beagleboard/c/GzAMt9MFzC4 And then repeated multiple times with no resolutions: https://discussion.fedoraproject.org/t/how-to-debug-lots-of-wlp2s0-ctrl-event-signal-change-messages-on-journalct/72555 https://www.google.com/search?q=%22CTRL-EVENT-SIGNAL-CHANGE+above%3D1%22 Just pure bonkers.
I made a patch and it was applied upstream https://w1.fi/cgit/hostap/commit/?id=c330b5820eefa8e703dbce7278c2a62d9c69166a
Thanks a TON!
