We still have MariaDB 10.1 in Fedora 26, in base repos, and default version of openssl in F26 is OpenSSL v1.1. Since we still use OpenSSL 1.0 for MariaDB, it brought some issues like https://bugzilla.redhat.com/show_bug.cgi?id=1471159 where two different versions of OpenSSL were loaded into one process.

That is why I decided to give it a try and backported OpenSSL 1.1 support from MariaDB 10.2 to 10.1.

The patches taken are available here: https://src.fedoraproject.org/rpms/mariadb/c/39a24f0850321cbb97f3dd671a17e29fa4bdb4d4?branch=f26

If you don't plan to back-port this feature to 10.1 version, I definitely understand it, this bug is basically meant to let you know that there might be real issues caused by having MariaDB 10.1 built with OpenSSL 1.0 on Fedora 26, and that back-porting the patches is working..

Also, I'd be glad to hear any worries which this back-port might bring, or if there are some more patches related to OpenSSL that I omitted.
