Thanks for raising this issue.
The patch is merged on all branches but not released.We will release the
next release ASAP.
But on the other hand, if you build an OpenStack cloud through kolla and be
the internet, you'd better use an external network(interface) for internet
access. There are lots of port
enabled on the internal network. like MariaDB, Memcached.
