- Add sa_family_t typedef for Windows in platform_compat.h
- Add forward declaration of struct ll_queue in ll_queue.h to fix warnings
- Replace arpa/inet.h includes with platform_compat.h in:
tun_linux.c, etcp_connections.c, route_lib.c, route_bgp.c,
utun_instance.c, routing.c, utun.c, packet_dump.h, config_parser.c
- All 22 tests pass on Linux
- Changed routing_pkt_from_etcp_cb to new signature for etcp_bind
- Register callback via etcp_bind(instance, 0, callback) in routing_create
- Implement full routing in routing_pkt_from_tun_cb using route_table_lookup
- Send packets to ETCP via etcp_send with ID prefix (0x00)
- routing_add_conn/routing_del_conn now deprecated (no-op)
- Added etcp_unbind in routing_destroy for cleanup
The pn_init() function now sets up etcp_int_recv as callback for pn->output.
Tests that manually poll pn->output need to reset this callback to NULL.
Changes:
- test_pkt_normalizer_etcp.c: Reset callback after pn_init() for client and server
- test_pkt_normalizer_standalone.c: Reset callback after pn_init()
This allows tests to manually poll output queue without conflicting
with the automatic callback mechanism.
Test Results: All 19 tests PASS
- 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.
- 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.
