evgeny 38c9f229bc stcp: ed25519 pubkey exchange in handshake, fix instance destroy segfault, fix chat_tcp_test
- 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

evgeny d773f1724a refactor: STCP connections as ETCP links (is_tcp)
- Add is_tcp, tcp_link, tcp_reconnect_* fields to ETCP_LINK
- Remove transport_link from ETCP_CONN, add tcp_link_count
- stcp_link: replace embedded etcp_conn with pointer; add etcp_link backpointer
- stcp_link: link_rx_cb routes ETCP data to etcp_conn_input
- stcp_link: call on_close_cb in close
- New TCP functions: etcp_link_enter_ready_tcp, etcp_tcp_link_start_connect,
  etcp_tcp_link_start_reconnect, tcp_link_close_cb, etcp_tcp_send
- etcp_link_new: handle NULL conn for TCP links; skip enter_init for TCP
- etcp_link_close: close stcp_link for TCP
- etcp_encrypt_send: redirect TCP to etcp_tcp_send (skips AES-CCM)
- tcp_server_on_link: create ETCP_LINK(is_tcp=1) + enter_ready_tcp
- etcp_connect: TCP addrs -> etcp_tcp_link_start_connect
- Remove ctx->tcp_link/tcp_ready
- test_stcp_traffic: find stcp_link via links->is_tcp instead of transport_link
- 66/68 tests pass; 2 STCP tests expected to fail (integration not complete)

evgeny dfe9d36783 wip: STCP TCP chat integration — diagnostics, invite TCP fallback, test infra 2026-08-06 18:41:41 +03:00
evgeny dc8c9f7875 fix: cm_invite_pending — deferred free + cancelled guard
Корень краша: cm_handle_invite_info_resp вызывал cm_invite_cleanup(inv)
без unlink из invite_list — висячий указатель при conn_mgr_destroy → SIGSEGV.

Механизм защиты:
- cancelled:1 в cm_invite_pending — блокирует все коллбэки после cancel
- cm_invite_cancel: cancelled=1 первой строкой, deferred free через uasync_post
- Все коллбэки (NCD, TCP ready/close, overall timer): guard + DEBUG_WARN
- Success path: temp_nq=NULL (передача владения), вызов cm_invite_cancel
- INV_CANCEL логи: skip (NULL) / done — видно что реально сделано

evgeny ef637d33a6 auto_socket: модуль авто-управления сокетами при изменении сетевых интерфейсов + fix pre-existing ASAN-багов
- 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

evgeny 4c1ea11022 conn_mgr: split handler into router (routed) and direct paths
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.

evgeny 85f23e0a94 conn_mgr: move etcp_router bind/unbind from per-group to instance level
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.

evgeny be0e76c9a6 debug: реорганизация категорий — SYS(1), ETCP(4) расширен, CONNECTION(3) очищен; fix stcp_client.c sock_err до connect()
Категории:
- DEBUG_CATEGORY_SYS=1: u_async + ll_queue + memory + timing (было 4)
- DEBUG_CATEGORY_ETCP=4: ETCP + normalizer + BBR (было 3)
- DEBUG_CATEGORY_CONNECTION=3: только события статуса линка/подключения (INFO)
- DEBUG_CATEGORY_KEEPALIVE=21: только периодический мониторинг (DEBUG)
- Удалены: NORMALIZER, BBR, CONNECTIVITY
- Устаревшие DB_SYNC → CHAT_SYNC + MEMBER_SYNC (предыдущий коммит)

CONNECTION+INFO — только: Connection UP/DOWN, Link UP/down, Link initialized/added,
  NAT address init/changed, init server/client.
CONNECTION+DEBUG — retry, collision, reinit, socket register.
KEEPALIVE — init_timer SUPPRESSED, timer started, keepalive skipped.
REINIT — ETCP+INFO.
Connection status changed — GENERAL (пользовательский callback).
Dedup link_status: if(old_link_status) перед Link down.
Убран дублирующий Conn:%s из Link down, добавлен link_id в client added link.
Молчаливые ошибки: +DEBUG_ERROR в 15 местах (merkle_sync, member_sync, db_sync).

Fix: stcp_client.c — socket_get_error() вызывался ДО connect(), проверяя
застарелое errno вместо ошибки connect(). Неблокирующий connect() возвращает
-1+EINPROGRESS (норма), но сравнивался с мусором → ложный FAIL.
Все 4 STCP-теста исправлены (68/68 pass).

Evgeny cf1843e586 fix: etcp_connect_timeout_tb=0 in utun_instance_create (missing init)
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.

- 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
2026-08-03 18:50:11 +03:00
evgeny c2191aad3b chat: user-friendly INFO logs for invite/connect flow
- chat_sync.c: invite entry, JOINED/TIMEOUT messages

  TCP connect/ready/close, membership check send/receive/confirm/deny,
  overall timeout
- node_conn_direct.c: NCD event names instead of numbers
2026-08-02 20:32:01 +03:00

2026-08-01 17:52:56 +03:00
evgeny 8237d92be9 fix: NCD close UAF + conn name + init_connections per-link ni_tmp
- ncd_down_cb: defer callback removal+close via uasync_call_soon to avoid
  UAF in etcp_cbk_fire iteration (removing ncd_up_cb corrupts saved next ptr)
- ncd_recv_control_handler: use deferred close for CLOSE handlers instead of
  direct etcp_connection_close to avoid nested etcp_cbk_fire UAF
- node_conn_direct_open/open_node: use ni->node_name if available for
  conn name, fallback to 'n_<node_id>' instead of NULL
- init_connections: build ni_tmp in link loop with only current link's addr,
  preventing NCD from creating links for ALL addrs on first socket
- utun_instance_reload: same per-link ni_tmp fix
- init_connections/reload: set ni_tmp.node_name = client->name for
  test find_client_link by name

- chatgui: call utun_instance_set_topo_group_enabled(0)
2026-07-19 08:33:33 +03:00
Evgeny c594375023 fix: derive node_id from pubkey instead of privkey
sc_derive_node_id() hashed the private key, while invite links
(joindialog.cpp) hashed the public key — giving two different
node_ids for the same keypair.

Removed sc_derive_node_id(), kept only sc_derive_node_id_from_pubkey().
All callers updated to use pubkey-based derivation.

Evgeny a7ecee01f5 etcp: replace connections linked-list with indexed ll_queue, add state/ref_count lifecycle
- Remove ETCP_CONN.next linked-list, UTUN_INSTANCE.connections list/count
- Unified connections in single ll_queue indexed by peer_node_id (0=pending)
- struct conn_queue_entry { peer_node_id, conn* } for uniform queue data
- Connection lifecycle via etcp.c: create→pending, conn_ready→indexed, close→detach+deferred free
- Close split: phase1 detach from external world, phase2 deferred via uasync_call_soon
- etcp_conn_set_peer_node_id: reindex on ID change (WARN)
- etcp_conn_ref_take/free: blocking close until refcount returns to 0

Evgeny 3c3d9a65d9 refactor: переименование route_node/route_bgp в topo_node/topo_bgp
Файлы: route_node.* route_node_lmdb.* route_bgp.* -> topo_node.* topo_node_lmdb.* topo_bgp.*

Структуры:
- ROUTE_BGP -> TOPO_BGP, ROUTE_BGP_CONN_ITEM -> TOPO_BGP_CONN_ITEM
- NODEINFO -> TOPO_NODE, NODEINFO_Q -> TOPO_NODEQ, NODEINFO_PATH -> TOPO_NODEPATH
- NODEINFO_ROUTES -> TOPO_NODESUBNETS, NODE_CONNECTIVITY -> TOPO_CONNECTIVITY
- wire: NODEINFO_MSG -> TOPOMSG_NODE, NODEINFO_IPV4_* -> TOPOMSG_*4 и т.д.
- memory: NI_IPV4_* -> TOPO_*4, NI_IPV6_* -> TOPO_*6
- ROUTE_SUBCMD_* -> TOPO_SUBCMD_*, ETCP_ID_ROUTE_ENTRY -> ETCP_ID_TOPO_ENTRY

Функции:
- route_bgp_* -> topo_bgp_*
- nodeinfo_* -> topo_node_*
- route_node_* -> topo_node_*
- route_node_lmdb_* -> topo_node_lmdb_*

Смысл: отделение механизма формирования топологии узлов от IP-роутинга.

Evgeny 8756f561be build: extract libutun.a from src/ + add db_sync module + etcp API, BBR improvements
- Add libutun.a (noinst) containing all src/*.c except utun.c
- utun binary now links libutun.a + libuasync.a
- tests/Makefile.am simplified: all tests link libutun.a instead of
  manual .o file lists (removed ~70 lines of boilerplate)
- Add db_sync module: distributed content-addressed DB with LMDB
  backend, peer-to-peer sync via etcp_router (svc 0x20)
- etcp API: etcp_send_in_order(), etcp_clear_inflight_queues(),
  verify_packet_signature(), BBR getters
- BBR: adaptive threshold (1/4 of pipe-min instead of hardcoded)
- route_bgp/etcp_connect: STCP transport support in NODEINFO
- conn_mgr: NODEINFO_ADDRS doc for nat_type/transport/proto fields
- Cleanup: removed AUDIT_FINDINGS.txt, filelist.txt, nat.txt

Evgeny 389ef00da6 refactor: split socket meta 'type' into config_type and nat_type — separate config (PUBLIC/NAT/PRIVATE) from detected NAT (EIM/STRICT/DIRECT) across NODEINFO, conn_mgr, route_bgp, route_node, etcpmon; win32 compat fixes (memmem, SHUT_WR, tun test_mode, tcp_proxy guards) 2026-07-02 18:58:34 +03:00
Evgeny a01e2f0899 tun_enabled config + socks/http stress test (50 reqs, 2 workers)
- config_parser: tun_enabled в [global] (по умолчанию yes), не дефолтить
  tun_ifname если TUN не нужен
- utun_instance: уважать tun_enabled, чистые дефолты tcp_proxy TUN
- socks_proxy: фикс дэдлока — reply сразу после CONNECT, без ожидания DATA
- utun.conf.sample: документирован tun_enabled, tun_ifname
- test_socks_http_proxy: 50 запросов (SOCKS+HTTP), 2 воркера параллельно,
  файлы 1k..100k, сверка через cmp, python http.server + curl

Evgeny 393a641e18 socks/http proxy client: SOCKS5 + HTTP CONNECT через ETCP
Добавлен модуль socks_proxy.c/h — SOCKS5 и HTTP CONNECT proxy на клиенте.
Использует tcp_io для локальных TCP соединений, туннелит трафик через
существующий ETCP-протокол (ETCP_ID_TCP_PROXY/ETCP_ID_TCP_PROXY_CLIENT).

Конфиг [tcp_proxy_client]:
- socks_enabled/socks_addr — включить SOCKS5 сервер на указанном IP:PORT
- http_proxy_enabled/http_proxy_addr — включить HTTP CONNECT сервер
- Можно включать TUN, SOCKS и HTTP прокси одновременно или раздельно

Весь трефик идёт через exit node (tcp_proxy_server), менять exit не пришлось.

Evgeny 53d41d5c62 fix: use-after-free in route table — add route_delete before u_free in route_bgp_update_my_nodeinfo and route_bgp_process_nodeinfo, relax routes_overlap to allow hierarchical routes
Root cause: when bgp->local_node was reallocated (changed=1), old route
entries remained with stale v_node_info pointing to freed memory. The freed
memory got reused by a BGP peer's NODEINFO_Q, causing route_lookup to return
wrong node_id (b3b2b1b0afaeadac instead of local), which then failed at
etcp_route_send with 'no BGP route' and dropped packets to 10.23.2.1.

Changes:
- route_node.c: route_delete(old) before u_free + route_insert(new) after alloc
- utun_instance.c: remove duplicate route_insert (now atomic inside function)
- route_bgp.c: route_delete before freeing old peer NODEINFO_Q
- route_lib.c: routes_overlap now rejects only exact prefix+network duplicates
- tests/Makefile.am: add route_lib.o to test_route6_lib
