Evgeny 355824792d Fix test_etcp_simple_traffic for new tun_if API 2026-02-07 02:30:53 +03:00
Evgeny 5a7107b855 Simplify tun_if: unified init, write, close API with queue-based reads
- 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

Evgeny 528c1ddd00 WIP: Current normalizer changes before error handling fix 2026-02-04 23:24:25 +03:00
Evgeny 5840e77e1e Fix test_pkt_normalizer_etcp: fixed packet normalizer and test verification logic

Evgeny 1e5a381f06 Prepare for ETCP traffic flow debugging - analysis complete
Analyzed current ETCP test infrastructure and identified key issues:
- TUN permission problems blocking traffic flow testing
- Missing packet tracing and traffic analysis tools
- Need for TUN-less test mode for connection debugging
- Lack of traffic generation and protocol verification tools

Identified comprehensive debugging requirements:
- Connection establishment verification (INIT handshake)
- Packet flow tracing through ETCP pipeline
- Retransmission and ACK behavior analysis
- RTT/bandwidth calculation validation
- Multi-link failover testing
- Encryption/decryption verification

Ready to implement enhanced traffic flow debugging capabilities.

Evgeny e048b10899 Fix: ETCP module compilation errors and build system issues
- 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).

Evgeny 56dfd2f0df Ревизия: добавлены DEBUG сообщения для ошибок и предупреждений
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.
