Description of problem:
SELinux is preventing ip6tables from 'ioctl' accesses on the directory /sys/fs/cgroup.

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

If you believe that ip6tables 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 'ip6tables' --raw | audit2allow -M my-ip6tables
# semodule -X 300 -i my-ip6tables.pp
