    Description

      This is a spin-off from MDEV-4379. Quoting from there

      If a mariadb is configured to bind to a hostname, it should be possible for it to bind to both the ipv4 and ipv6 addresses defined for that hostname if the host is set up that way. This is the standard behavior with server software (openldap, postfix, apache, etc). Most also include options to force binding only to a specific ip protocol if desired. This is helpful for dual stack systems where it may be desired to have a server bind to both the ipv4 and ipv6 addresses for serving clients.

            The lack of support for multiple sockets is what breaks dual-stack support on OpenBSD.

            MDEV-5536 also needs to expand the number of listening interface descriptors.

            Still looking forward to this. We're up from 10.0 to 10.4, but IPv6 support is still broken without this.

            I request a change around WaitForMultipleObjects(), in the very unlikely case wait_events.size() exceeds MAXIMUM_WAIT_OBJECTS=64. This would require at least 40 IP addresses for a name, and I'm not sure how it is possible, but the check must be there. Looks OK otherwise.

            All merged. Feels good to finally close of 6.5 year old bugs.

            Thanks rinat.ibragimov for the code. It is helping my MDEV-5536 significantly.
