- src/tun_windows.c: Windows TUN implementation improvements
- src/control_server.c: removed premature return statement

- Добавлена опция tun_test_mode в конфиг для работы без реального TUN устройства
- Добавлены функции для работы с очередями TUN в тестовом режиме
- Добавлен API для программного создания instance из структуры конфига
- Создан тест test_routing_mesh.c с 3-instance mesh топологией
- Ключи генерируются автоматически и распределяются между instance
- Split TUN implementation into platform-specific files:
- tun_if.c: Common code (queues, callbacks, statistics)
- tun_linux.c: Linux TUN/TAP implementation (/dev/net/tun + ioctl)
- tun_windows.c: Windows Wintun implementation (wintun.dll + IP Helper)
- Update tun_if.h with platform abstraction layer:
- tun_platform_init/cleanup/read/write/get_poll_fd
- Platform handles: fd (Linux), WINTUN handles (Windows)
- Windows implementation features:
- Dynamic loading of wintun.dll with graceful error handling
- IP Helper API for IP address and MTU configuration
- HANDLE-based uasync integration
- Clear error message if wintun.dll is not found
- Update build system:
- configure.ac: Detect Windows (mingw/msys/cygwin)
- src/Makefile.am: Conditional compilation of tun_linux/tun_windows
- tests/Makefile.am: Link platform-specific TUN objects
- Add wintun.dll and wintun.h to lib/ directory
- All 22 tests pass on Linux
- Ready for MSYS2 UCRT64 Windows build
- Fixed race condition: routing_add_conn called before etcp->normalizer was assigned
- Moved routing_add_conn from pn_init to etcp_connection_create after normalizer init
- Added routing.h include to etcp.c
- Fixed tests: disable routing callback on output_queue to keep packets for test verification
All 19 tests now pass.
- New struct tun_if with internal queue for incoming packets
- Single tun_init() does everything: create TUN, set MTU=1500, up, register in uasync
- tun_write() for outgoing packets
- tun_close() cleans up everything including queue
- Removed: tun_create, tun_set_ip, tun_set_up, tun_set_mtu, tun_read, tun_get_config
- Removed: utun_instance_register/unregister_sockets (now internal)
- Updated utun_instance to use new tun_if* pointer
- Updated test_etcp_two_instances for new API
- 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).
Добавлены комплексные DEBUG сообщения в критические точки проекта:
- **ETCP протокол** (etcp.c): ошибки инициализации криптоконтекста, выделения памяти для очередей, коротких пакетов, сбоев шифрования
- **ETCP соединения** (etcp_connections.c): ошибки установки публичных ключей, расшифровки пакетов, шифрования при отправке
- **TUN интерфейс** (tun_if.c): ошибки создания устройства, настройки IP/MTU, чтения/записи
- **Конфигурация** (config_parser.c): ошибки выделения памяти для структур конфигурации, парсинга IP-адресов
- **Маршрутизация** (routing.c): ошибки выделения памяти для таблиц, отсутствие маршрутов
Все DEBUG сообщения используют существующую систему категорий (CRYPTO, MEMORY, CONFIG, ROUTING, TUN, CONNECTION, ETCP) и предоставляют детальную информацию для диагностики проблем.
