Mariadb-client is unable to negotiate to TLSv1.2. I have tested this
with server versions: 10.1.37-MariaDB Gentoo Linux mariadb-10.1.37
10.1.34-MariaDB Gentoo Linux mariadb-10.1.34
. It should be noted that only the client version:
Ver 15.1 Distrib 10.1.37-MariaDB, for debian-linux-gnu (x86_64) using
readline 5.2 is unable to connect to the servers listed previously when
TLSv1.2 is enforced. However clients on other operating systems tested:
Ver 15.1 Distrib 10.1.34-MariaDB, for Linux (x86_64) using readline 7.0
Ver 15.1 Distrib 10.1.37-MariaDB, for Linux (x86_64) using readline 7.0
are able to connect just fine. Upon further inspection, looking at
packet traces with WireShark it appears that the Debian client is only
attempting to negotiate a connection with TLSv1.1, which is blacklisted
while the Gentoo clients are able to negotiate at TLSv1.2. The Debian
client fails and prints "ERROR 2026 (HY000): SSL connection error:
unknown error number" to stdout.
