Description Mikhail 2021-03-22 15:19:08 UTC
Description of problem:
SELinux is preventing /usr/lib/systemd/systemd-rfkill from using the 'fowner' capabilities.

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

If you believe that systemd-rfkill should have the fowner capability 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 'systemd-rfkill' --raw | audit2allow -M my-systemdrfkill
# semodule -X 300 -i my-systemdrfkill.pp

Comment 1 Zdenek Pytela 2021-03-22 17:47:04 UTC
There currently seems to be a problem with XFS and new kernels. Could you try if it reproduces with an older kernel from the 5.11 series?
