- 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).
✅ Implemented compact packet dump format for better readability
✅ Added configurable packet dump modes (compact vs full)
✅ Created log_packet_compact() for high-frequency packet logging
✅ Added packet type and timestamp extraction for better analysis
✅ Single-line format: [ETCP] SEND: link=0x... type=0x02 ts=123 len=77
✅ Full hex dump available at DEBUG_TRACE level for small packets
✅ Maintains compatibility with existing multi-line format
✅ All tests pass with new packet dump functionality
The new format provides:
- Single-line packet info for better readability
- Packet type and timestamp extraction
- Configurable output modes
- Efficient logging for high-frequency packet flows
Example output:
[ETCP] SEND: link=0x55f2c3e4a5c0 type=0x02 ts=12345 len=77
[ETCP] RECV: link=NULL type=0x03 ts=0 len=25
- Reduced test timeout from 10s to 3s
- Decreased monitoring interval from 1000ms to 200ms
- Shortened server initialization wait from 2s to 0.5s
- Added immediate exit on successful connection
- Test now completes in ~0.5s vs ~10s previously
- All tests pass without crashes or memory leaks
The test_etcp_two_instances now runs 20x faster and exits immediately
upon successful connection establishment.
✅ Fixed critical segmentation fault (SIGABRT) in test_etcp_two_instances
✅ Added comprehensive timer debug logging with DEBUG_CATEGORY_TIMERS
✅ Created uasync_print_resources() function for resource diagnostics
✅ Created utun_instance_diagnose_leaks() function for leak analysis
✅ Fixed cleanup order - cancel timers before destroying uasync instances
✅ Fixed timer cancellation to properly update counters
✅ Fixed socket cleanup to unregister from uasync before destruction
✅ Added detailed diagnostic output for memory leak tracking
✅ All tests now pass without crashes
Key fixes:
- Fixed use-after-free in test cleanup sequence
- Added proper timer leak detection and cleanup
- Enhanced debug capabilities for future debugging
- Fixed ETCP socket cleanup to prevent resource leaks
The test_etcp_two_instances now runs successfully without segmentation faults.
- Made get_current_time_units() function globally accessible in etcp.h
- Improved packet dump formatting for better debugging clarity
- Added link timing tracking with last_recv_local_time and last_recv_timestamp
- Fixed packet parsing to properly skip timestamp bytes
- Enhanced connection state monitoring and error handling
- Removed obsolete etcp_connections.c4 debug file
- Updated test output formatting for better readability
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.
