During May 2025, Tietz extended the kamailio/kamailio repository by implementing WebSocket Secure (WSS) support within the TLS RPC interfaces. This work involved enhancing the TLS module’s RPC endpoints, specifically tls_list and tls_kill, to recognize and manage WSS connections using protocol enumeration (PROTO_WSS). By focusing on targeted C programming and network programming techniques, Tietz improved operational visibility and control over secure WebSocket traffic without introducing unnecessary code complexity. The update strengthened the security posture of the system and laid groundwork for future RPC-based WSS tooling, demonstrating a deep understanding of RPC design and protocol extension within a production codebase.

May 2025 monthly summary for kamailio/kamailio: Implemented WebSocket Secure (WSS) support in TLS RPC interfaces, enabling listing and termination of WSS connections via tls_list and tls_kill. This extends the TLS module RPC surface to PROTO_WSS, improving observability, security, and operational control over WSS traffic. No major bugs fixed in this period for this repo. Overall impact: stronger security posture, easier WSS management, and a foundation for future RPC-based WSS tooling. Technologies/skills demonstrated: TLS RPC extension, WebSocket Secure (WSS), protocol enumeration (PROTO_WSS), RPC design, and focused code changes with minimal surface area.
