- 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.
