evgeny 38c9f229bc stcp: ed25519 pubkey exchange in handshake, fix instance destroy segfault, fix chat_tcp_test 
- u_async.c: process immediate_queue BEFORE epoll_wait in uasync_poll
- stcp_link.c: defensive NULL etcp_conn/etcp_link in stcp_link_close

  add deferred drain in both Phase J and L
- stcp.h/c: STCP_HS_ENC_CLIENT 6→38, STCP_HS_ENC_SERVER 7→39,
  exchange ed25519_pubkey in both handshake directions
- etcp_connections.c: copy peer_ed25519 from STCP to ETCP_CONN in
  etcp_link_enter_ready_tcp; guard link->etcp in tcp_link_close_cb
- chat_sync.c: fix lk->conn NULL dereference for TCP links

- tools/chat_tcp_test: change transport udp→tcp
 2026-08-07 00:48:27 +03:00
evgeny d773f1724a refactor: STCP connections as ETCP links (is_tcp) 
- Add is_tcp, tcp_link, tcp_reconnect_* fields to ETCP_LINK
- Remove transport_link from ETCP_CONN, add tcp_link_count
- stcp_link: replace embedded etcp_conn with pointer; add etcp_link backpointer
- stcp_link: link_rx_cb routes ETCP data to etcp_conn_input
- stcp_link: call on_close_cb in close
- New TCP functions: etcp_link_enter_ready_tcp, etcp_tcp_link_start_connect,
  etcp_tcp_link_start_reconnect, tcp_link_close_cb, etcp_tcp_send
- etcp_link_new: handle NULL conn for TCP links; skip enter_init for TCP
- etcp_link_close: close stcp_link for TCP
- etcp_encrypt_send: redirect TCP to etcp_tcp_send (skips AES-CCM)
- tcp_server_on_link: create ETCP_LINK(is_tcp=1) + enter_ready_tcp
- etcp_connect: TCP addrs -> etcp_tcp_link_start_connect
- Remove ctx->tcp_link/tcp_ready
- test_stcp_traffic: find stcp_link via links->is_tcp instead of transport_link
- 66/68 tests pass; 2 STCP tests expected to fail (integration not complete)

Evgeny 11ab897fe5 chatgui: fix RTT display 10x overstatement (DB stores 0.1ms, displayed as ms); remove unused rtt_avg_100 2026-07-26 08:57:02 +03:00
Evgeny 0381f4df89 Убраны TCP_TIMESTAMPS и TCP_KEEPALIVE из lwip_tcp_opts.h (не используются, конфликтовали с ws2ipdef.h на Windows) 2026-07-17 17:49:15 +03:00
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 1f4fe37fe5 proxy: rename + simplify + backpressure 
- tcp_proxy/remote_proxy → tcp_proxy_client/tcp_proxy_server
- Все proxy файлы перенесены в src/proxy/
