- topo_group: глобальный реестр TOPO_NODE по node_id, ref_count=0 при создании
- BGP-обмен активируется для всех групп (а не только дефолтной)
- Протокол: group_id добавлен в WITHDRAW/TABLE_REQ/TABLE_COMPLETE/ERR_GROUP_MISMATCH
- Per-connection коллбэки заменены на instance-level conn_status

Evgeny 58b9f28149 fix chatgui: prevent invite deadlock on connection flap
cs_on_conn_down: remove invite state zeroing on disconnection.
Only timeout callbacks and explicit protocol end (CS_MSG_ERROR,
transition to JOIN phase) clear the invite state.

Connection flap now causes automatic retry:
  conn_up → pending_invite_ch_id != 0 && !info_req_timer → resend
  CHANNEL_INFO_REQ. No deadlock possible.

Evgeny f617dcd68e db_sync: LMDB→SQLite, multi-instance, etcp_api, chatgui integration
- src/db_sync: LMDB replaced with SQLite (separate tables per instance: db_sync_name_id)
  TTL index (author, timestamp), WAL mode, per-instance peers/timers
  opaque DB_SYNC_INSTANCE* handle, insert callback, select API
  new fields: author_signature, delivered_peers, delivery_chain
  transport: etcp_api direct P2P (was etcp_router)

- src/db_sync.h: user-oriented API docs, multi-instance lifecycle

- lib/Makefile.am: liblmdb sources removed
- lib/sqlite3.c+h: SQLite amalgamation added

- topo_node: LMDB→SQLite (src/topo_node_sqlite.c moved from chatgui)

- chatgui: real db_sync.c replaces db_sync_stub.c
  chat_core: db_sync_insert_signed + dual-write insert callback
  utun_node: db_sync_init/destroy replaces chat_sync_init/destroy
  CMakeLists: stubs removed, real db_sync.c added

Evgeny 19a4505a03 chat_sync: новый протокол синхронизации чата вместо ChatPropagator
- gui_bridge.h/cpp — кросс-поточные асинхронные коллбэки uasync↔GUI
- chat_sync.h/c — протокол синхронизации (INIT_SYNC/RESP, SEND_DATA, PUSH/ACK, SYNC_DONE)
- DbManager полностью переписан: per-channel таблицы msg_<ch> + peers_<ch>,
  4 ключа в channels, signature, protocol/rtt в node_addresses, sync-методы
- ChatPropagator удалён, заменён на chat_sync
- db_sync_stub.c — заглушки для сборки chatgui без LMDB-версии db_sync
- db_schema.md актуализирован под новую схему

Evgeny 2cd38988e6 AGENTS: add ASAN build instructions 2026-07-02 15:49:10 +03:00
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

- sc_compute_public_key_from_private via EVP_PKEY_new_raw_private_key

- Remove all TinyCrypt code (~860 lines), always use OpenSSL
- Remove TinyCrypt from build system, drop test_crypto/test_ecc_encrypt

Evgeny 3bf178475d Docs: Added cp/кп command note and important development guidelines in Russian 2026-01-22 10:03:58 +03:00
Evgeny 56dfd2f0df Ревизия: добавлены DEBUG сообщения для ошибок и предупреждений
Добавлены комплексные DEBUG сообщения в критические точки проекта:

- **ETCP протокол** (etcp.c): ошибки инициализации криптоконтекста, выделения памяти для очередей, коротких пакетов, сбоев шифрования
- **ETCP соединения** (etcp_connections.c): ошибки установки публичных ключей, расшифровки пакетов, шифрования при отправке
- **TUN интерфейс** (tun_if.c): ошибки создания устройства, настройки IP/MTU, чтения/записи
- **Конфигурация** (config_parser.c): ошибки выделения памяти для структур конфигурации, парсинга IP-адресов
- **Маршрутизация** (routing.c): ошибки выделения памяти для таблиц, отсутствие маршрутов

Все DEBUG сообщения используют существующую систему категорий (CRYPTO, MEMORY, CONFIG, ROUTING, TUN, CONNECTION, ETCP) и предоставляют детальную информацию для диагностики проблем.

Evgeny f6c337bd1c FINAL: Encryption fully implemented with tests. Add etcp_connections_get_crypto_stats signature fix and tests in Makefile.am 2026-01-18 21:20:56 +03:00
Evgeny c869ccf174 Major refactoring: Tasks 1-4 complete
Task 1: Migrate to GNU Autotools
- Add configure.ac, Makefile.am files (root, src, u_async, tests)
- Add autogen.sh bootstrap script
- Create INSTALL.autotools guide
- Update .gitignore for autotools
- Old Makefile backed up as Makefile.old

Task 2: Refactor typedef struct → struct STRUCT_NAME
- Remove 24 of 28 typedef struct declarations
- Convert to struct STRUCT_NAME pattern per AGENTS.md
- Files affected: routing, memory_pool, packet_buffer/pool,
  tun_if, etcp_sockets/connections, config_parser,
  pkt_normalizer, secure_channel, utun_instance, etcp
- Code now 86% compliant with AGENTS.md style guide

Task 3: Clean up legacy tests
- Remove 7 obsolete test files (connection*, sc_lib, udp_secure, etc.)
- Update 4 test files to new API (epkt_t → struct ETCP_CONN)
- Clean Makefile of legacy references
- Test suite reduced from 17 to 10 focused tests

Task 4: Replace fprintf with debug system
- Replace 60 fprintf(stderr) calls with DEBUG_ERROR/WARNING macros
- Add debug_config.h includes to all modified files
- Use appropriate DEBUG_CATEGORY_* for each error type
- Debug output now runtime-configurable

Impact: 32 files modified, ~350 lines changed, all 4 tasks complete,
build system modernized, code follows AGENTS.md, debugging improved.
