Description Ian Laurie 2024-11-28 01:15:18 UTC
Description of problem:
SELinux is preventing /usr/lib/systemd/systemd-resolved from 'getattr' accesses on the file /cgroup:[4026531835].

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

If you believe that systemd-resolved should be allowed getattr access on the cgroup:[4026531835] 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 'systemd-resolve' --raw | audit2allow -M my-systemdresolve
# semodule -X 300 -i my-systemdresolve.pp
