RHEL7, internal IPv6 networking, 3 node Galera cluster

Hi, can you open a pull request for your contribution. Similar to other open source projects, the MariaDB Foundation needs to have shared ownership of all code that is included in the MariaDB distribution. The easiest way to achieve this is by submitting your code under the BSD-new license.

The other alternative is to sign the code contribution agreement which can be found here: https://mariadb.com/kb/en/mariadb/mca/

Please indicate in a comment in your pull request that you are contributing your new code of the whole pull request, including one or several files that are either new files or modified ones, under the BSD-new license or that you have filled out the contribution agreement and sent it.

Test something like this (after MDEV-15496 is fixed) as the wsrep_sst_common parses the address into host/port components already:

Untested is if the logic in check_pid_and_port. lsof seems to expects escaped however grep has non literal meanings for '[ipv6]'. This whole function needs to be rewritten to use the capabilities of lsof to get the right output parsing its output (example - see wsrep_sst_xtrabackup-v2)

Can we have this looked at? Currently Galera does not support internal IPv6 network using rsync SST method. We have an application that wants to use Galera over IPv6 with rsync and they cannot get it to work. They have indicated that my workaround above did not work for them. I have requested their server.cnf file.

In my understanding this has been fixed on more recent versions.
