Major architectural changes: - utun_instance_run() now does single iteration instead of mainloop - Added tun_read_callback() to handle TUN device packets - Added utun_instance_register_sockets() for uasync integration - Mainloop moved to main() with proper signal handling - Removed parse config file functions from debug_config - all fprintf replaced with DEBUG_* macros Files changed: - src/utun.c: Added mainloop, signal handlers, proper init order - src/utun_instance.c: Added callback, socket registration, single-run - src/utun_instance.h: Added declarations, tun_socket_id field - u_async/debug_config.c: Removed file parsing and auto-reload - u_async/debug_config.h: Removed file functions, added categories - changelog.txt: Added all changes Breaking changes: - debug_parse_config_file() removed (use debug_parse_config() only) - etcp crypto integration needs fixing (separate issue) AGENTS.md principles followed: - No backward compatibility preserved - Removed 103+ lines of legacy code - Added statistics tracking - Clean architecture: create -> init -> register -> run -> destroyv2_dev

Формат кодограммы: |
||||
------------------ |
||||
Каждая кодограмма состоит из обязательного заголовка и опциональных секций: |
||||
1. Обязательный заголовок (4 байта): |
||||
[ID high][ID low][Timestamp high][Timestamp low] |
||||
- ID: 16-битный циклический номер (0 = служебный пакет без данных) |
||||
- Timestamp: время отправки в единицах 0.1 мс (циклическое) |
||||
|
||||
2. Опциональные секции (одна или несколько): |
||||
а) Подтверждения (ACK) - заголовок 0x01: |
||||
[0x01][count][(id_hi,id_lo,ts_hi,ts_lo)×count][last_delivered_hi,lo][last_rx_hi,lo] |
||||
- count: количество пар ID+timestamp (1-32) |
||||
- last_delivered_id: последний ID, доставленный получателю |
||||
- last_rx_id: последний полученный ID (для синхронизации прогресса) |
||||
б) Запросы ретрансмиссии - заголовок 0x10-0x2F: |
||||
[0x10+(count-1)][(id_hi,id_lo)×count][last_delivered_hi,lo][last_rx_hi,lo] |
||||
- count: (заголовок & 0x0F) + 1 (1-32) |
||||
- last_delivered_id, last_rx_id: для синхронизации состояния |
||||
в) Полезная нагрузка - заголовок 0x00: |
||||
[0x00][данные...] |
||||
- Данные произвольной длины |
||||
|
||||
Пакет может содержать несколько секций (например, ACK + данные). Секция с данными |
||||
обычно идет последней. |
||||
|
||||
|
||||
Кодограммы с этими секциями обрабатываются в etcp_connections (в этих кодограммах всегда только одна секция): |
||||
г) Init запрос - заголовок 0x02: (у инициирующей стороны всегда есть publick key удаленного пира) |
||||
[0x02] [my_node_id 64bit] [my publick key, binary] [my mtu high] [my mty low] [keepalive high] [keepalive low] |
||||
- Инициирует первый connection и + etcp instance |
||||
|
||||
д) Init подтверждение - заголовок 0x03: |
||||
[0x03] [my_node_id 64bit] [my mtu high] [my mty low] [keepalive high] [keepalive low] |
||||
|
||||
г) Channel init запрос - добавляем дополнительный канал для подключения |
||||
[0x04] [my_node_id 64bit] [keepalive high] [keepalive low] |
||||
- Инициирует новый connection в существующем etcp instance |
||||
|
||||
д) Channel init подтверждение - заголовок 0x05: |
||||
[0x05] [my_node_id 64bit] |
||||
- Подтверждение иниуиализации дополнительного канала |
||||
|
||||
е) Reset запрос: |
||||
[0x06] |
||||
- отправляется в ответ отправителю, если соединение не инициализировано и получен пакет не init (0x02, 0x03) |
||||
|
||||
При получении init получатель пакета должен: |
||||
- удалить ETCP_LINK с этим ip_port если оно есть |
||||
- создать новый ETCP_CONN с этим node_id. если уже существует подключение с этим node_id - вызвать etcp_reset (функция сброса окон неподтвержденных данных и нумерации) |
