- 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
- etcp_connections.h: add WIRE_OVERHEAD, IP_UDP_OVERHEAD_V4/V6, SC_ENCRYPT_OVERHEAD
(properly accounts for v6 IP(40)+UDP(8)+SC(3)+CCM tag(16) = 67 vs old UDP_HDR_SIZE=28)
- etcp_connections.c etcp_encrypt_send: use WIRE_OVERHEAD instead of UDP_HDR_SIZE
- etcp_connections.c send_init_response: clamp padding to max_data = mtu - WIRE_OVERHEAD
- chat_core_priv.h: add addr_type_from_ip() classifier
- chat_profile.c, chat_sync.c, member_sync.c: use classified addr_type instead of hardcoded 0
- chat_sync.c: skip zero nat_addr in JOIN, fall back to interface_addr
- topo_node_sqlite.c, member_sync.c: remove addr_type=0 filter from SELECT/DELETE
- chat_profile.c, member_sync.c: DELETE all addresses (not just addr_type=0)
- 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
Root cause: instance_lite_restart was creating new thread without
re-setting g_event_handler, causing all chat events (CHANNEL_UPDATED,
CONNECT_RESULT, etc.) to be silently dropped after app restart.
Fixes:
- instance_lite_restart: save/restore g_event_handler across hard restart
- instance_thread restart loop: re-call chat_event_set_handler after uasync_create
- utun_bridge_restart: call instance_lite_set_event_handler before restart
- AppEventHandler SharedFlow replay: 1 → 16 to not lose early init events
- ViewModel: added diagnostic logging for channel/connect events
- Keep diagnostic logs in instance_lite (set_handler, chat_event_forward NULL check)
- instance_event_handler: removed static for cross-block forward declaration
- auto_socket.c/h: создание/удаление UDP сокетов автоматически при изменении интерфейсов через netlink/route socket
При auto_sockets=yes пропускает ручные [server] сокеты
Тип сокета: PUBLIC если публичный IP, иначе NAT
Для новых сокетов добавляются линки ко всем активным NCD-соединениям
При удалении интерфейса линки убираются, сокет закрывается
Platform-agnostic API для использования из Android/chatgui
- node_conn_direct.h/c: ncd_add_socket_links / ncd_remove_socket_links — управление линками на конкретном сокете
- socket_monitor.h/c: экспорт socket_monitor_update_if_addr для auto_socket
- config_parser.h/c: опция auto_sockets в [global]
- init_sockets(): пропуск ручных сокетов при auto_sockets=yes
- utun_instance: интеграция auto_socket_init/destroy
- media_delivery: fix stack-buffer-overflow ack[3] → ack[9]
- topo_node: fix heap-use-after-free в topo_group_update_my_nodeinfo — сохранение node_id/ver перед registry_store, использование return value
- etcp.c:466: %d→%s for log_name (was printing garbage like -2012603448)
- etcp_connections.c:2235: Server type %d→%s with server_type_str()
- etcp_connections.c:845,1578,1587: type=%d/nat_type=%d→%s with helpers
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.
1. etcp_on_down: add down_link param — log the specific lost link + remaining
Connection DOWN — link 192.168.40.247:2122 lost, remaining: [::1]:6669, [::2]:9970
Connection DOWN — closing, links: ... (for reinit/close)
2. etcp_on_link_down: pass the triggering link through to etcp_on_down
3. etcp_update_log_name: always check registry for node_name
(n_5a1b... → SM-A525F when name is available in registry)
Add helper functions server_type_str() and nat_type_str() to convert
CFG_SERVER_TYPE_* and NAT_TYPE_* codes to readable names.
Now: Add Socket type=PUBLIC instead of type=1
self-detect check: type=PUBLIC nat=UNKNOWN instead of type=1 nat_type=0
etcp_update_log_name: if name is empty, look up peer_node_id in topo_node_registry
and use node_name (e.g. 'SM-A525F') instead of empty or generic name.
Result: [45C2->03D3 [SM-A525F]] instead of [45C2->03D3 []]
- etcp_on_up: list up-link addresses after connection summary
- etcp_on_down: show all link addresses that were lost
- Link UP (server/client): add addr=X
- Connection established: add addr=X
- Link closed: add addr=X before traffic stats
- Link down (keepalive timeout): add addr=X
Now: [conn] Link 1 UP (server, mtu=1600, addr=192.168.40.247:2122)
- 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.
utun_instance_create() allocated with u_calloc (zeroed) but never
set etcp_connect_timeout_tb. utun_instance_create_from_config() had it
at line 371, but utun_instance_create (used by chatgui) was missing.
Timer with tb=0 fires instantly → CLOSE sent before handshake completes.
Diagnostics confirmed: value_tb=0, tb=0, delta_tb=0 on Windows chatgui.
- block_availability: status column (0=processing, 1=completed)
- md_ba_complete_block(): DELETE old + check exists + INSERT new id
- BLOCK_PROCESSING subcmd (0x10) — INSERT with new id, no REPLACE/IGNORE
- BLOCK_RELAY_FULL subcmd (0x11) — redirect when source/relay at capacity
- relay_block_ctx: downstream forwarding from chunk file
- md_file_load: per-file source download limit (max_downloads_per_file)
- RELAY_FULL from source node when at capacity
- relay_full handler: retry existing peers, not just new ones
