Description of problem:
SELinux is preventing iptables from 'ioctl' accesses on the directory /sys/fs/cgroup.

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

If you believe that iptables should be allowed ioctl access on the cgroup 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 'iptables' --raw | audit2allow -M my-iptables
# semodule -X 300 -i my-iptables.pp
