- route_node_format_all(): format all BGP nodes to snprintf buffer
- control_server: 'nodes' action sends ETCPMON_RSP_ACTION_RESULT (0x89) with text
- etcpmon_protocol.h: new response type + struct, increase MAX_MSG_SIZE to 32K
- etcpmon_client: on_action_result callback, send_action via send_request with seq_id
- etcpmon_gui: ETCPMonActionResult popup window class with EDIT multiline,
on_action_result creates popup (same size as main) or appends text + scrolls
Add route_node_dump_all() in route_node.c that walks bgp->nodes list
and outputs per-node info: node_id, name, version, pubkeys, IPv4/IPv6
addrs/sockets/subnets, paths with hop list, connectivity state, conn_mgr.
Wire 'nodes' action in control_server to call this function.
Root cause: test1 used lks() (INIT links up) but conn_mgr needs BGP NODEINFO.
Nodeinfo arrives after INIT, so test1 must wait for it.
Also made result volatile to prevent loop optimization.
Both req (INIT_REQUEST) and resp (INIT_RESPONSE) point to pkt->data.
resp->peer_port at offset 23-24 overwrites req->src_ipv4[0..1] at same offset.
Save src_ipv4/src_port before building the response.
- Extract ETCP_INIT_REQUEST_PKT / ETCP_INIT_RESPONSE_PKT named structs
- Replace anonymous structs and manual offset parsing with typed struct access
- Add src_ipv4/src_port fields (V2) to INIT REQUEST for DIRECT detection
- Server compares reported client addr with observed src; match + public IP → NAT_TYPE_DIRECT
- Skip STUN NAT check for DIRECT links
- route_bgp: handle NAT_TYPE_DIRECT → NAT_VERIFIED_DIRECT in handle_nat_info
- Add ed25519_public_key[32] to NODEINFO struct for pubkey distribution
- Add ed25519_public_key[32] to ROUTE_BGP (derived from X25519 privkey at init)
- Add ROUTER_FLAG_SIGNED (0x08) to SVC_ROUTE_HDR flags byte
- router_send_one_flags: when is_signed, sign [hdr][payload] and append 64-byte sig
- etcp_router_recv_cb: verify Ed25519 signature when ROUTER_FLAG_SIGNED set
- New API: etcp_router_conn_send_signed()
- Drop signed packets if sender node not in routing table or no Ed25519 key
- 5 unit tests in test_etcp_router_unit.c covering OK/tampered/unknown/no-key/short
last_recv_local_time was not set in the server INIT processing path,
causing the keepalive timer to see a stale timestamp and trigger a
false link-down → route_bgp_remove_conn() right after reconnect.
Routes could be deleted before the first normal packet from the
client updated the timestamp via process_decrypted.
- debug_get_category_name(): replace switch/case with table lookup in g_debug_categories[]
- etcpmon_gui: remove hardcoded cat_names[], create labels/radios dynamically from server CSV
- Add acked_bytes/acked_packets to struct ETCP_LINK (init, reset, increment per ACK)
- Add DEBUG_CATEGORY_BBR (23) for BBR-specific debug output
- Add BBR input/output DEBUG_DEBUG around bbr_main call in etcp_ack_recv
- Add "bbr" category name to debug_config and etcpmon GUI
- Вынесена общая логика обработки фатальных ошибок сокета
- Обработчик: close сокета, обнуление коллбэков, аварийный drain, вызов on_error
- Устранён use-after-free: пулы освобождаются до вызова on_error
- flush_write_buf возвращает int (0=ok, 1=error/tc destroyed)
- Все ошибки аллокации write_buf ведут к вызову on_error (ENOMEM)
- Обновлён header: документация в актуальное состояние
Check queue_find_data_by_index(ack_q) before creating a new ACK_PACKET
in ETCP_SECTION_PAYLOAD handler. Previously every duplicate packet
created a new entry in ack_q, and with links blocked (inf_block) the
queue grew without bounds.
- etcp_conn_reset: queue_resume_callback after clear_queue (input_queue,
input_send_q, input_wait_ack) to prevent suspended callback deadlock
- is_connection_established: check conn->initialized (reliable across
reinit) instead of link->initialized (never cleared on reinit)
- test: force etcp_conn_reinit after server recreation so conn_ok
waits for fresh INIT handshake
- test: guard send_packets() with is_connection_established in reconnect
phases to avoid sending data while conn is down
