Evgeny 3c3d9a65d9 refactor: переименование route_node/route_bgp в topo_node/topo_bgp 
Файлы: route_node.* route_node_lmdb.* route_bgp.* -> topo_node.* topo_node_lmdb.* topo_bgp.*

Структуры:
- ROUTE_BGP -> TOPO_BGP, ROUTE_BGP_CONN_ITEM -> TOPO_BGP_CONN_ITEM
- NODEINFO -> TOPO_NODE, NODEINFO_Q -> TOPO_NODEQ, NODEINFO_PATH -> TOPO_NODEPATH
- NODEINFO_ROUTES -> TOPO_NODESUBNETS, NODE_CONNECTIVITY -> TOPO_CONNECTIVITY
- wire: NODEINFO_MSG -> TOPOMSG_NODE, NODEINFO_IPV4_* -> TOPOMSG_*4 и т.д.
- memory: NI_IPV4_* -> TOPO_*4, NI_IPV6_* -> TOPO_*6
- ROUTE_SUBCMD_* -> TOPO_SUBCMD_*, ETCP_ID_ROUTE_ENTRY -> ETCP_ID_TOPO_ENTRY

Функции:
- route_bgp_* -> topo_bgp_*
- nodeinfo_* -> topo_node_*
- route_node_* -> topo_node_*
- route_node_lmdb_* -> topo_node_lmdb_*

Смысл: отделение механизма формирования топологии узлов от IP-роутинга.

Evgeny 4914348557 etcp_router: транзитные очереди per (src,dst) с backpressure + унификация etcp_send 
- TRANSIT_QUEUE: отдельная очередь на каждую пару src+dst узлов
- ll_queue с хеш-индексом для быстрого поиска transit-очередей
- backpressure через waiter на send_input_q (threshold=0, один пакет за вызов, round-robin)
- Очередь создаётся при первом пакете который не получается отправить напрямую, удаляется при опустошении
- Унифицирован etcp_send: единый путь queue_data_put(send_input_q) для UDP (normalizer->input) и STCP (tx_queue)
- Убран STCP-ветвления из router_forward_transit/drain_cb
- Исправлено перекрытие ll.data и tq->q в TRANSIT_QUEUE (добавлены явные поля src_node_id/dst_node_id)
- Фикс лика dgram в tx_queue_cb/client_tx_queue_cb (добавлен queue_dgram_free)
- transit_queues живут внутри ETCP_CONN, инициализируются лениво, очищаются в etcp_connection_close (до pn_deinit) и stcp_link_close

Evgeny 4862c30261 add CFG_SERVER_TYPE_LOCAL (type=local) and UNKNOWN semantics: PRIVATE/LOCAL hidden from nodeinfo, PRIVATE blocks incoming INIT, LOCAL accepts; UNKNOWN treated as PUBLIC; self-detection of PUBLIC IP on incoming INIT; filter LOCAL from NAT checks and connectivity 2026-07-02 19:30:08 +03:00
Evgeny 389ef00da6 refactor: split socket meta 'type' into config_type and nat_type — separate config (PUBLIC/NAT/PRIVATE) from detected NAT (EIM/STRICT/DIRECT) across NODEINFO, conn_mgr, route_bgp, route_node, etcpmon; win32 compat fixes (memmem, SHUT_WR, tun test_mode, tcp_proxy guards) 2026-07-02 18:58:34 +03:00

Evgeny 1f4fe37fe5 proxy: rename + simplify + backpressure 
- tcp_proxy/remote_proxy → tcp_proxy_client/tcp_proxy_server
- Все proxy файлы перенесены в src/proxy/
- Конфиг: [tcp_proxy]→[tcp_proxy_client], [remote_proxy]→[tcp_proxy_server]
- Убран subcmd CONNECTED (0x02) — клиент шлёт DATA сразу после CONNECT
- Backpressure: etcp_router_waiter_register/cancel через ll_queue threshold waiter
- Клиент: recv_cb send fail → tx_buf+waiter, не tcp_recved() (окно lwIP=0)
- Сервер: read_cb send fail → pause_buf+waiter, пауза read_id
- CLOSE/ERROR отправляется только после drain всех очередей
- Fail: conn не найден/closed → send ERROR вместо CLOSE/silent drop
- PROTOCOL.md: полная архитектура с диаграммами состояний и потоков

- etcp_connections.h: поле bbr_loss_since_ack для per-link учёта потерь в байтах
- etcp_bbr.c: везде где BBR_CWND_MIN_TARGET — умножить на mss (юнит-мизматч пакеты/байты)
  - bbr_quantization_budget, bbr_set_cwnd, bbr_bound_cwnd_for_inflight_model, bbr_probe_rtt_cwnd
  - bbr_init_lower_bounds: инициализация inflight_hi из cwnd (был ~0U навсегда)
