Description Jack Greiner 2025-01-10 04:21:32 UTC
Description of problem:
Setting the power profile using powerprofilesctl to any profile will trip SELinux.

Example command: powerprofilesctl launch -p performance glxgears

This will change the performance govenor to performance, and then launch glxgears. An SELinux warning will follow shortly afterwards.
SELinux is preventing power-profiles- from 'write' accesses on the file scaling_governor.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that power-profiles- should be allowed write access on the scaling_governor file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'power-profiles-' --raw | audit2allow -M my-powerprofiles
# semodule -X 300 -i my-powerprofiles.pp
