WARNING: Forcing protocol to TCP due to option specification. Please explicitly state intended protocol.

I just started getting this warning message since upgrading slackware current. I ran bash -x and bash -v and can't find why this is triggered.

The warning message does not appear if you use the value "127.0.0.1" instead of "localhost" inside the configuration file:

# Host name (or IP address) of MySQL server e.g localhost
CONFIG_mysql_dump_host='127.0.0.1'

Read here: https://mariadb.com/kb/en/mysql-command-line-client/

Chapter: Linux/Unix
If hostname is not specified or hostname is localhost, then Unix sockets are used.
In other cases (hostname is given and it's not localhost) then a TCP/IP connection through the port option is used.
Note that localhost is a special value. Using 127.0.0.1 is not the same thing. The latter will connect to the mysqld server through TCP/IP.

Thanks. Helped.
