Worked on the ntop/nDPI repository to enhance stability, memory efficiency, and cross-platform reliability in C. Focused on stabilizing ndpiReader’s statistics handling for duration-based live captures by refactoring memory management and lifecycle logic, which reduced crashes and improved data structure reuse. Introduced dynamic allocation for ndpi_flow_info’s src_name and dst_name fields, optimizing RAM usage by allocating buffers only as needed per IP version and ensuring proper deallocation. Addressed Windows build issues in Proto Unit Tests by resolving MinGW-specific errors, improving CI reliability. Applied skills in C programming, memory management, and unit testing to deliver safer, more efficient network processing features.

Jul 1, 2025July 2025 performance summary for ntop/nDPI: Implemented a memory-optimized refactor by making ndpi_flow_info's src_name and dst_name dynamically allocated based on IP version. This eliminates pre-allocated IPv6 buffers when not needed, reducing RAM usage significantly. The change includes null-pointer safety checks and proper deallocation when flow info is freed, improving safety and reliability under high-load conditions. Commit reference: 4eff2cdb9991eed51e7e00e4dcc2f5fa1955cf17 ("Refactor: make src_name/dst_name dynamically allocated to reduce RAM usage (#2908)").

Jun 1, 2025Monthly work summary for 2025-06 focusing on ntop/nDPI ndpiReader stabilization and reliability improvements. The primary focus was fixing memory management and lifecycle issues in statistics handling during duration-based live captures, resulting in safer reuse of data structures, improved stability, and reduced risk of crashes. The changes introduced a centralized reset of statistics per thread after cleanup of all flow roots and included refactors to initialization, reset, and freeing sequences.
