router_handle_data_packet выбрасывал физический conn, а router_incoming_q_cb
восстанавливал его через topo_group_find_conn_for_node, который возвращает NULL,
когда у узла-источника нет пути в топологии. В итоге callback сервиса (routing,
conn_mgr) получал conn=0x0. Теперь физический conn сохраняется в rconn->recv_conn
и прокидывается в deliver.
standby.h/c: duty-cycle ACTIVE/SLEEP, standby_wait() будит в burst сразу,
в SLEEP — до следующего burst; notify_network_activity для раннего пробуждения.
Интеграция (по флагу UTUN_HAVE_STANDBY, десктоп без изменений):
- conn_mgr: bg_ping/candidate_ping в SLEEP defer через standby_wait
- route_connectivity: probe_node откладывается (PROBE_STATUS_DEFERRED)
- topo_group_connect: пауза между попытками — активный режим 1с, фон standby_wait
- jni_bridge/ConfigProvider/NetworkActivityMonitor: set_active + сетевая активность
- chat_setting: standby_active_sec/sleep_sec/min_sleep_sec
+ юнит-тест test_standby (31 проверок)
- Добавлен device_type (1 байт, CLIENT_TYPE_*) в INIT_REQUEST и INIT_RESPONSE
- Добавлен keepalive_interval (2 байта) в INIT_RESPONSE
- STCP handshake расширен с 43 до 46 байт (device_type+keepalive)
- negotiate_keepalive(): оба desktop/server → min, иначе (есть mobile) → max
- keepalive_interval вынесен в UTUN_INSTANCE для использования в handshake
- stcp_client_connect() принимает device_type и keepalive_interval
- peer_device_type/peer_keepalive_interval передаются через stcp_link в ETCP_LINK
- ntp_node_time.c: respond to TIME_SYNC only when peer is unsynced (not always)
Prevents infinite 10-byte ping-pong that ate bandwidth when both sides synced.
- pkt_normalizer.c: add in_total_pkts/in_total_bytes increments in
etcp_input_ready_cb (real send path), matching pn_packer_send (test path).
- conn_mgr_core.c/conn_mgr_priv.h: full INVITE_INFO_RESP with channel info
auto_socket.c: create_iface_tcp_socket returns stcp_server* instead of int,
ifa->v4_tcp/ifa->v6_tcp now properly track the created server, preventing
duplicate bind/listen on every reconcile_iface call.
etcp_connections.c: tcp_socket_add now resolves interface_addr via
get_interface_ip_by_index/get_interface_ipv6_addr_nl for any type (not just
PUBLIC), preventing NAT TCP v4 sockets from being destroyed due to INADDR_ANY.
- 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
- stcp_server: send handshake response BEFORE on_ready to prevent ETCP INIT data mixing into client recv buffer (crc mismatch)
- conn_mgr: relax peer_node_id match for INVITE_INFO_RESP when peer_node_id==0 (STCP connections)
- chat_tcp_test: remove invalid 'local' outside function
- node_put/node_update_verified: set online=1 on INSERT (nodes created when conn is UP)
- channel_peers_all: fix peer_needed calculation (atl byte was missing)
- cs_send_channel_join: add proto byte to address serialization matching all parsers
conn_mgr_router_recv_handler (etcp_router_bind): DIRECT_REQ, INTERM_EXCHANGE, DISCONNECT
conn_mgr_direct_recv_handler (etcp_bind): INVITE_INFO_REQ, INVITE_INFO_RESP
Each transport path now has its own handler — no more mixed concerns.
svc_id=17 (ETCP_RT_ID_CONN_MGR) is a singleton resource — bind once
at utun_instance_init, unbind once at utun_instance_destroy.
Previously each conn_mgr (one per group) called bind/unbind separately,
causing 'overwriting' and 'not bound' WARNs on every group init/shutdown.
Handler dispatches by group_id from message — no need for per-group binding.
- member_sync apply_items: empty payload is normal sync completion, not error
- topo_node_sqlite node_load: no addresses is normal for stub/seed nodes
- conn_mgr_core: node skipped when not in routing (normal for nodes w/o addrs)
- topo_group send_nodeinfo: downgrade ERROR→WARN in DEBUG category
- db_sync INIT_RESP: protocol details belong in DEBUG, not INFO
cm_invite_fail and cm_handle_invite_info_resp: always close invite's NCD
handle before freeing the invite struct. Previously the NCD close was
skipped when nq->handle != NULL (success path never closed it at all),
leaving cm_invite_ncd_callback registered with a dangling pointer.
On subsequent NCD DOWN event the stale callback caused SIGSEGV.
- conn_mgr_core.c: убрана запись node_name из cm_handle_invite_info_resp
- topo_node_sqlite.c: name в nodes не перезаписывается пустой строкой
- android_jni_bridge.c: bridge_get_node_name читает peers_<ch>.userinfo если nodes.name пуст
node_conn_direct:
- ncd_init_cb: skip UP when links_up==0, ncd_up_cb delivers when link comes up
- close/force_close: handle_count safety checks, callback clearing
- open/open_node case 2: create links on reused dead conn
- ncd_create_links: skip duplicate link on same conn (stale->etcp==conn)
- set_callback: optional callback change on live handle
conn_mgr:
- cm_ncd_callback: DOWN only delivers event (handle stays alive)
- cm_ncd_callback: TIMEOUT force_close BEFORE cm_deliver_event
- cm_deliver_event: read handle fields to locals before callback (reentrany-safe)
- INVITE_INFO_REQ/RESP: add duplicate cmd byte for direct-send protocol
- cm_handle_invite_info_resp: search invite by group_id in channel conn_mgr
Android:
- node_id computed by sc_derive_node_id_from_pubkey in C, not Kotlin
- utun_bridge_join_channel: recompute node_id, log mismatch
- invite_link_c: compute nodeId from pubkey via sc_derive_node_id_from_pubkey
- NativeLib.deriveNodeId, InviteLink.kt uses C function
- CONN_MGR entries: replace dynamic array with ll_queue (hash=256, key_size=8)
cm_find_entry now O(1) via queue_find_data_by_index
cm_ensure_entry uses queue_entry_new + queue_data_put_with_index
cm_entry_cleanup removes from queue and frees entry
- TOPO_GROUP_NODE: replace handles** array with single CONN_MGR_HANDLE*
remove topo_node_handle_register/unregister/count — dead indirection
nq->handle = h / nq->handle = NULL in all call sites
- TOPO_GROUP_NODE: remove dead fields dirty, best_socket, tranzit_data/count
dirty replaced with local variable in nat_detection.c
tranzit_data removed from wire format (TOPOMSG_NODE), serialize, deserialize
update struct layout: one field per line with comments
- CM_V6_ANY for :: socket (matches all v6 addr classes)
- sin6_scope_id from s->netif_index (not from local_addr where :: has scope=0)
- getnameinfo in stcp_link_connect to preserve scope_id in addr string
- scope_id in cm_invite_tcp_connect, ncd_create_links, connect_create_links_v6, cm_bg_ping_to_node
Android chatgui:
- New MemberListScreen with member list, detail card, edit dialog
- Link status dots (green/red/grey) per address in detail card (1s poll)
- Self-node name coloured green
- ChatScreen: people icon in TopAppBar
IPv6 autoconnect fixes (3 bugs in conn_mgr/topo):
- topo_node_sqlite_node_load: load v6 addresses from DB
- topo_node_registry_store: merge v6_addrs into existing node
- cm_sock_v6_classify: wildcard [::] treated as CM_V6_DIR
- cm_add_v6_link: htons(port) was missing
Memory fixes:
- strdup→u_strdup in bridge (7 instances)
- u_realloc cap update before success check (3 instances)
- char sql[256]→[512] for truncated SELECT
Chat member hash now includes addresses for change detection
Linux chatgui:
- Link status dots in AccountList detail panel (1s poll)
- Self-node name in green in member list
