- 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
- utun_instance.c: move stcp_server_list_destroy_all to Phase J (before ETCP),
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
- test_stcp.c: update stcp_server_create/stcp_client_connect callsites
- tools/chat_tcp_test: change transport udp→tcp
- Assign ETCP_ID_NAT_DETECTION = 0x02, etcp_bind in create, etcp_unbind in destroy
- nat_detection_receive_cbk: own packet dispatcher (PING_REQ/RESP, NAT_INFO/CHECK_REQ)
- 4 handle_* become static internal, send_nat_check_req stays static (dead code)
- Rename TOPO_* -> NATDET_*: all subcommands, structs, message types
- Remove all NAT/PING constants and structs from topo_group.h
- Remove dispatch lines and subcmd_name cases from topo_group_receive_cbk
- API: clear sections (lifecycle/internal service/control/test helpers)
- trigger_checks: marked with IMPORTANT note about call order (must be after add_to_senders)
- Renamed TOPO_BGP to TOPO_GROUP with topo_group_id (64bit)
- Added TOPO_GROUPS container (ll_queue group_list) in UTUN_INSTANCE
- Memory pools moved from TOPO_GROUP to TOPO_GROUPS (instance-level)
- Default group: TOPO_GROUP_UTUN = 0x8000000000000000
- topo_groups_get_default() searches by group_id, not just first entry
- All topo_bgp_* renamed to topo_group_*; function signatures updated
- Files: topo_bgp.h/c -> topo_group.h/c
- Rename NAT types: OPEN->EIM, RESTRICTED->STRICT across all code
- Add flat addr list {type,ip,port,socket_id} to NODEINFO (NODEINFO_IPV4_ADDR)
- Add NODEINFO_IPV4_SOCKET_META for per-socket metadata
- Add NODE_CONNECTIVITY with per-type probe status and min_rtt
- New module: route_connectivity.c/h (probing engine with socket fallback)
- STRICT verified addresses excluded from NODEINFO broadcast
- Trigger probing on new/updated BGP node, cancel on remove/withdraw
- Update NAT type names in etcpmon GUI
req_pkt memory could be freed by etcp_send callback before pending->request_id
was assigned. Store request_id in local variable and use it for pending.
- Changed request_id from uint64_t to uint32_t in BGP_PING_REQUEST/RESPONSE
- Added uint16_t reserved field after subcmd for proper alignment
- Updated next_ping_req_id from uint64_t to uint32_t in ROUTE_BGP
- Fixed all log format strings from %016llx to %08x
- All 26 tests passing
1. Добавлен via_conn в struct route_ping_pending - отслеживает через
какое соединение (third_conn) отправлен запрос на ping
2. route_ping_cancel_for_conn теперь отменяет pending при падении ЛЮБОГО
из двух conn: владельца линка (link->etcp) ИЛИ third_conn (via_conn)
3. nat_link_check_cb проверяет link->nat_check_status == IN_PROGRESS
перед обработкой - защита от race condition когда conn упал раньше
чем пришел ответ
4. Убраны избыточные DEBUG-логи, оставлены только информативные
- Исправлена критическая ошибка: использовалось na->link->conn вместо
na->link->etcp (struct ETCP_LINK.conn = ETCP_SOCKET*, а .etcp = ETCP_CONN*)
- Добавлен подробный дебаг в 4 места:
* route_ping_send_req_addr - при создании pending
* route_ping_cancel_for_conn - при поиске и отмене
* route_bgp_remove_conn - состояние линков перед отменой
* etcp_connection_close - очистка линков при закрытии
- route_bgp_remove_conn теперь отменяет pending NAT checks перед удалением
- Добавлена route_ping_cancel_for_conn: ищет pending запросы для conn,
отменяет таймеры, сбрасывает arg->link = NULL, удаляет из списка
- struct nat_check_arg вынесена в route_bgp.h для видимости из route_ping.c
- После отмены pending, статусы линков с NAT_CHECK_IN_PROGRESS сбрасываются в NONE
- etcp_connections.c: парсинг NAT IP через memcpy (сохраняет NBO)
- route_bgp.c: убраны ntohl() для IP в NAT detection и route_bgp_send_nat_info
- route_ping.c: убран htonl() для IP в ping request
- тесты: обновлены ожидания NBO для nat_ip
- route_ping.c: burst mode - send next ping immediately on response
- route_ping.h: add target_ipv4/target_port/pubkey to BGP_PING_REQUEST
- test_nat_detection.c: add test for ping without embedded pubkey
- test_etcp_simple_traffic.c: use dynamic ports + fix timebase units
- Makefile.am: show test execution time in ms
- Add get_node_v6_sockets() function in route_node
- Add local_defaultroute_ip6 field to ETCP_SOCKET
- Fix IPv6 address logging in bind, init, new connection
- Fix socket lookup for IPv6 in init_connections
- Fix route_ping_handle_req to support both v4 and v6 sockets
