wpa_supplicant floods log with scan error when ssid is not present

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



New to wpa_supplicant and wpa_cli and am using systemd-resolved as
network manager.

I have everything working reasonably well, but struggled with one
thing. I get this
error flooding the journal log:

Jul 01 13:26:10 pi4 wpa_supplicant[420]: wlan0: Failed to initiate sched scan
Jul 01 13:26:19 pi4 wpa_supplicant[420]: wlan0: Failed to initiate sched scan
Jul 01 13:26:28 pi4 wpa_supplicant[420]: wlan0: Failed to initiate sched scan

This occurs when there is a known ssid in the config, the ssid is
enabled by wpa_cli, but this ssid is not visible and the wlan is not
connected to any other ssid.

If I disable the network: 'wpa_cli disable network 0', it stops
spamming the log. If It stays enabled yet I connect to another ssid,
it does not spam the log. It is only when it is not connected and
there is an ssid in the config that it cannot 'see'.

It appears that when wpa_supplicant is complaining that it 'Failed to
initiate sched scan' it will immediately connect to that known network
when it reappears. As long as the ssid is not available, and is in the
list (in /etc/wpa_supplicant.conf) and 'enabled' by wpa_cli the log
gets spammed with this. It seems a bit strange that this would be an
unexpected situation: that wpa_supplicant may not be connected yet
have an ssid listed that may not be available.

I am running this on an RPi which is running RPiOS with systemd and
have tried this with wpa_supplicant.service (dbus version edited to
specify wlan0 so that it can save the configs) and with
wpa_supplicant@wlan0 (without dbus).

Any help appreciated.
