Attach packet drivers to initially empty ETCP connections. Share BLE neighbor
tracking and group fallback between desktop and Android in cgathui_common.
Deliver join links through a dedicated Write/Indicate characteristic with
independent fragmentation queues, application acknowledgements, deduplication
and bounded retries. Merge LAN/BLE discovery and add a separate Bluetooth
invitation reception setting to both clients.
Validation: 230 core tests, BLE transport/BlueZ/UI tests, ASAN/UBSAN,
Linux GUI and Android builds, and Windows backend cross-compilation.
Physical Android/Linux invitation exchange passed with either GATT initiator.
The Android-initiated run also verified all 32 ETCP packets of 1500 bytes;
the desktop-initiated load run reached 7/32 within its 45-second time limit.
Keep the borrowed audio provider on UTUN_INSTANCE across chat service restarts.
Attach and detach Android voice from the core worker and reject DSP startup
after detach. Preserve TX owner epochs, pending slots and foreign-instance RX
isolation. Remove the unused cross-thread online API and keep its check local
to call.c.
Add eight lifecycle regressions with real cores and the Android host bridge.
Audit public call, DSP, clock, headless and desktop audio contracts and record
the findings and validation scope.
Validation: voice/desktop 38/38, four native call suites, native and both Android
ABI builds, full check 204/204 plus proxy/burst/load. JVM results remain Gradle
UP-TO-DATE (155 app and 15 router). No hardware runtime validation.
Require signed and encrypted call audio/video using static identity keys. Fix attachment service ID collisions and media download handle lifetime; isolate LAN tests and audit the shared service registry.
Receive keepalive through the owning ETCP link, preserve RX deadlines, and report routing metrics without TUN. Use independent netlink requests and track installed routes for rollback. Reject incomplete resource initialization and release partially constructed cores while preserving caller config ownership.
Validated startup failure and rollback, padded keepalive, standby, STCP traffic, transport lifecycle, dynamic sockets, and daemon startup. Real TUN/netlink checks passed in an isolated Linux network namespace; modified modules passed FreeBSD compilation checks.
Track visited nodes outside the signed body for all routed packet types. Recheck queued transit routes without losing FIFO priority, reject unknown-group transit, and suppress BGP announcements caused only by RTT jitter.
Document routing rules and wire format. Validate graph churn, REINIT, encrypted transit, malformed paths, loop drops and queue cleanup; full suite: 106 passed, 1 skipped, plus proxy integration and sanitizer checks.
Новый модуль src/radio (radio/radio_audio/radio_headless) — push-to-talk
радио поверх topo-групп, доставка аудио в канал, headless-режим и тесты.
Интеграция в chatgui (ptt_hotkey_manager, radio_audio_engine, радионастройки,
вызовы) и chatgui-android (RadioAudioEngine, RadioOverlayService, UI).
Полностью убрана фича периодического обмена CSV-метриками с Ed25519-подписью:
- ETCP_SECTION_METRICS и парсинг/верификация секции
- struct etcp_metrics, etcp_metrics_add_*/start/stop и снапшот-таймер
- мёртвый API on_metrics_rcvd/metrics_user_ptr (никто не подписан)
- link->remote_ed25519_pubkey (заполнялся только на клиенте → верификация на сервере всегда падала)
- stats_dir в UTUN_INSTANCE
Общий sc_stream_sign_* (деривация Ed25519 из X25519) и INIT-передача обоих ключей сохранены.
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)
- новый модуль etcp_keepalive.c/h: keepalive-пакеты, таймер, адаптивный период,
согласование при handshake вынесены из etcp_connections.c как есть
- протокол KEEPALIVE_REQ/RESP (0x09/0x0A): мобильный узел при смене active mode
шлёт желаемый режим; отвечающий считает max (standby при любом standby), не-мобильный
применяет как есть; инициатор применяет согласованный режим после RESP
- режимы: NORMAL (3с, адаптивный рост), STANDBY (30с, ka_pinned=1 без роста)
- active mode как событие: utun_add/remove_activity_cbk; подписчики topo_group
(nodeinfo) и etcp_keepalive (рассылка REQ всем линкам)
- 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
- 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
