Large number of crda failures

Large number of crda failures

[Adam Cottrel]

Hi,

On start up I am getting a large number of error faults reported with CRDA:-
➢ ies0600133 systemd-udevd[3949]: Process '/sbin/crda' failed with exit code 234
Typically, over 50 lines are reported to the syslogs

However, once the system has fully started, I do not get any issues with running:-
➢ iw reg set XX

These errors are doubling the boot time for Linux. My kernel is 4.14.4 and I am running a Debian base.

Please can someone advise what is going wrong?

Best,
Adam

Code 234 => exit(-EINVAL)
Could be that crda is started in a context where the COUNTRY environment variable is invalid, or started with an argument (crda must be run without argument).

Dear Jean-Pierre,

Thank you for getting back to me.

My regulatory settings are working, and so the errors might not be very important - however, it is important that know why they are happening.

This is very a good suggestion - I can see that my COUNTRY environment is not set. However, when I set COUNTRY the error code gets replaced with -7.

The CRDA always reports errors on startup, but my wireless regulatory domains are working normally. For example I can change them using the following commands:-
 # iw reg set XX
 # iw reg get 

Why do I still get warnings if the underlying mechanism is working OK?

Best,
Adam
