Description of problem:
SELinux is preventing firewalld from 'read' accesses on the directory netfilter.

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

If you believe that firewalld should be allowed read access on the netfilter directory 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 'firewalld' --raw | audit2allow -M my-firewalld
# semodule -X 300 -i my-firewalld.pp
