In May 2025, the team delivered foundational enhancements to the agent management and OpenVAS result pipelines, delivering measurable reliability and integration potential. Key work included introducing the Agent Controller Module in greenbone/gvm-libs with a new API surface for agent lifecycle management (create/update/authorize/delete), along with additional CMake options and integration groundwork for an agent-control service. We also addressed robustness and memory-safety gaps across components. In greenbone/gvm-libs, the zero-count fix for agent controller list handling ensures an empty list is returned instead of NULL, with tests updated accordingly. In greenbone/gvmd, port handling in OpenVASD result reporting was corrected to properly format and reuse port values, and redundant allocations were removed to reduce memory leaks. These changes improve stability, reduce runtime risk, and enable more reliable end-to-end automation and reporting. Business value and impact: - More reliable agent lifecycle management and service integration, enabling automation and easier onboarding of agents. - Safer memory management and correct data representations in scan results, reducing leak risk and potential formatting errors in reports. - Clear, test-covered changes aligned with performance reviews and future feature work.
