Description Sumit Bhardwaj 2018-11-14 07:59:52 UTC
Description of problem:
SELinux is preventing /usr/lib/systemd/systemd-timesyncd from 'getattr' accesses on the lnk_file /var/lib/systemd/timesync.

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

If you believe that systemd-timesyncd should be allowed getattr access on the timesync lnk_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# ausearch -c 'systemd-timesyn' --raw | audit2allow -M my-systemdtimesyn
# semodule -X 300 -i my-systemdtimesyn.pp
