mariadb/include/mysql/plugin_audit.h.pp
Hashim Syed b76760360a MDEV-12182 Add Client TCP Port Number to MySQL Audit Plugin Logs 
In environments with load balancers or proxies, the audit plugin logs
only the IP address, making it difficult to differentiate individual client
connections from the same IP.

Add a new 'port' field to the appropriate event objects to capture the
client's TCP port number. Populate the port field with thd->port  in the
appropriate functions. The audit plugin receives and logs this port field
along  with  other connection information, enabling better identification
of individual client connections.

are either new files or modified ones, are contributed under the BSD-new license.
