init accurately describes when conn->initialized=1, before keepalives establish UP.
Also fire etcp_fire_conn_status INIT at this point instead of create time.
- Add etcp_add_conn_status_cbk/remove/set — unified callback for all connections
- 4 statuses: NEW, UP, DOWN, DELETE — one subscription covers all connections
- Fire points in etcp.c: create→NEW, on_up→UP, on_down→DOWN, close→DELETE
- chat_sync.c: replace cs_on_new_conn+per-conn subs with cs_on_conn_status
- db_sync.c: same migration to instance-level callback
- cs_is_peer_online: use conn->links_up instead of link->link_status (was 0 during INIT handshake)
- chat_core_connect_auto: direct ETCP connect from SQLite (no BGP)
- auto_connect: parallel connect to peers with 3s timeout, retry 10s
- RTT saved to node_addresses on disconnect
- vertical status bar + circle badge with online count per channel
- ChannelListView prevents deselection
Added #ifdef __cplusplus / extern "C" { ... } / #endif to ~65 headers
in src/ and lib/, enabling the C library to be linked into C++ code (chatgui).
Fixed packet_dump.h (added missing header guard) and etcp_bbr.h
(#pragma once guard).
- UDP proxy: datagram relay client↔exit over ETCP
- ICMP proxy: echo ping relay client↔exit over ETCP
- Move via_node_id from per-forward-mapping to global tcp_proxy setting
- Support multiple concurrent tcp_proxy instances (no singleton g_tcp_proxy)
- Cap handshake padding to stay within 1472+overhead
- Handle non-TCP packets (UDP/ICMP) in tcp_proxy raw/tun input paths
- Add utun_instance_create_from_str() for test config creation
etcp_router: routable service packets with dst/src node_id
- etcp_router_bind/unbind: per-instance service handler registry
- etcp_route_send: send to node by id via BGP routing
- multi-hop forwarding through intermediate nodes
- loopback optimization (dst==self dispatches directly)
remote_proxy: exit node creating OS sockets on demand
- handles CONNECT/DATA/CLOSE via etcp_router
- non-blocking socket connect with uasync callbacks
- echo back response data to requesting node
tcp_proxy: etcp_transport for remote proxy
- via_node_id in mapping selects between sock/etcp transport
- unified handler for both tcp_proxy and remote_proxy roles
- config: forward = port -> ip:port via NODE_HEX [remote_proxy] section
tests: test_etcp_router (20 pkts bidirectional), test_remote_proxy (echo)
- Add route_bgp.c/h with BGP-like route exchange functionality
- Implement route_bgp_init/destroy for module lifecycle
- Add route_bgp_new_conn to send routing table on connection
- Implement route_bgp_receive_cbk for processing incoming routes
- Add route_table_delete_entry for individual route removal
- Extend ROUTE_ENTRY with endpoint_ip, endpoint_port, destination_node_id
- Add DEBUG_CATEGORY_BGP to debug_config.h
- Integrate BGP initialization into utun_instance_create
- Call route_bgp_new_conn from etcp_connections on link init
- Create integration test test_bgp_route_exchange.c
- Add route_bgp_delete_entry tests to test_route_lib.c
- Update Makefiles to include new module
Route exchange tested and working in both directions (client-server)
Changed from global bindings to per-instance bindings:
1. Added struct ETCP_BINDINGS in etcp_api.h:
- Contains array of callbacks[ETCP_MAX_BINDINGS]
- NULL means not bound
2. Updated UTUN_INSTANCE (utun_instance.h):
- Added field: struct ETCP_BINDINGS api_bindings
- Initialized to NULL by calloc in utun_instance_create
3. Updated API functions (etcp_api.h/c):
- etcp_bind(inst, id, callback) - per-instance binding
- etcp_unbind(inst, id) - per-instance unbinding
- Removed etcp_api_init/etcp_api_deinit (not needed)
- etcp_int_recv now uses conn->instance->api_bindings.callbacks[id]
4. Updated test_etcp_api.c:
- Separate callbacks for server and client
- Register via etcp_bind(server_instance, ...) and etcp_bind(client_instance, ...)
- Removed global etcp_api_init/etcp_api_deinit calls
Test passes: All 100 packets transmitted in each direction.
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
Implemented:
- etcp_send(conn, entry) - отправляет пакет в очередь normalizer
- etcp_bind(id, callback) - подписка на пакеты с определенным ID
- etcp_unbind(id) - отписка от пакетов
- etcp_recv(queue, arg) - коллбэк для маршрутизации пакетов по ID
- etcp_api_init/deinit - инициализация API
Integration:
- pn_init() теперь устанавливает etcp_recv как callback для pn->output
- Добавлены etcp_api.c/h в src/Makefile.am
- Добавлен etcp_api.o в тестовые зависимости
API использует первый байт кодограммы (cmd) как ID для маршрутизации.
ID=0 используется как default handler если нет специфичного binding.
