- Fixed incorrect init_connections() call in test_etcp_simple_traffic.c (was calling server_instance instead of client_instance)
- Fixed double free in timeout_heap_pop() when handling deleted elements
- Enhanced NULL pointer safety in uasync_print_resources() by removing complex heap manipulation
- Added debug logging to timeout_heap_pop() for better error tracking
Test results: test_etcp_simple_traffic now passes without double free errors
- Added missing structure members to ETCP_CONN (ack_packets_count, last_rx_ack_id, rtt_history, rtt_history_idx, total_packets_sent)
- Added missing bandwidth member to ETCP_LINK structure
- Fixed include path for ll_queue.h header
- Added math library linking (-lm) to build system
- Added etcp_loadbalancer.c to build sources
- Fixed forward declarations and function calls in ETCP modules
- Updated test dependencies to include loadbalancer object files
All simple compilation errors resolved, project builds successfully and tests pass (except TUN permission test which is expected in container).
- Deleted 11 obsolete debug/isolation test files
- Restored test_pkt_normalizer.c from git repository
- Added test_ecc_encrypt and test_routing to Makefile (2 new functional tests)
- Removed settings.o from PN_OBJS (settings.c deleted)
- Added crc32.o to SC_LIB_OBJS and ETCP_OBJS to fix linker errors
- Removed unused routing_get_stats() function (undefined routing_stats_t type)
- Updated changelog with detailed cleanup summary
Current test count: 16 tests in Makefile (14 original + 2 new)Active test files in tests/: 25 files (was 35)test_ecc_encrypt: PASStest_routing: Compilation OK
- Устранена критическая race condition: callback больше не пытается отменить уже удаленный waiter
- Упрощена логика управления waiter'ами: callback просто очищает указатель и отправляет следующий пакет
- Добавлена статистика pacing для анализа производительности
- Оптимизирована производительность: убраны лишние отладочные сообщения в hot path
- Улучшена обработка NULL от queue_wait_threshold: разделены случаи очередь пуста и ошибка
- Добавлена условная компиляция для отладочных сообщений в ll_queue.c
- Pacing теперь работает быстро при нулевых очередях: callback вызывается немедленно при опустошении
- Add utun VPN daemon with config parsing, control socket, routing, and TUN interface
- Refactor net_emulator/u_async to support multiple independent instances
- Replace linked-list timeout management with heap-based implementation
- Fix timeout processing bug (process timeouts after select)
- Add comprehensive random timeout and instance isolation tests
- Update Makefile to build utun and new test targets
