Evgeny	852ce401e7	Добавлен group_id в etcp_router и topo_group, удалён msg_transport - etcp_router: SVC_ROUTE_HDR (+8B), ETCP_ROUTER_CONN/TRANSIT_QUEUE хеши расширены под group_id - Все caller'ы (proxy, routing, conn_mgr, nat, chatgui, tests) обновлены - 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 - msg_transport полностью удалён из проекта 57/57 тестов	2 months ago
Evgeny	0b5a710fe6	etcp_connect + BGP_READY callbacks + router reconnect test - etcp_connect.c: async connect API with EARLY/LATE/BGP_READY callbacks - etcp_connect.h: declaration (via etcp_api.h) - connect_deliver: fix to preserve unfired callback nodes - etcp_set_routing_exchange_state: fires bgp_ready_cbk on TABLE_COMPLETE - route_bgp: TABLE_COMPLETE handler + route_bgp_send_table_complete - etcp.c: connections_count tracking, cleanup on close - test_etcp_router_reconnect: a-b-c topology with b restart (etcp_connect) - test_etcp_connect: unit tests for async connect API - etcp_router: inflight/retrans/close improvements - Various proxy/NAT/router cleanups	3 months ago
Evgeny	42d96f118d	fix: swap queue_entry_free/queue_dgram_free order in 27 places — prevents UAF when dgram_free accesses freed entry uasync: replace raw socket_node* handle with packed index — fixes UAF after socket_array realloc tcp_io: defer u_free in tcp_conn_destroy via uasync_call_soon — prevents callback-chain UAF tcp_io: guard read_cb/write_cb with NULL queue checks after deferred destroy tcp_io: save read_queue to local before queue_data_put + NULL guard after route_connectivity: linked-list probe_ctx — cancel all parallel probes before nq free	3 months ago
Evgeny	e765d62e43	etcp_route_send: add force parameter to bypass send_q limit for control messages CLOSE/ERROR/CONNECT and routing messages use force=1 to never be dropped by backpressure. Regular DATA uses force=0 (default).	4 months ago
Evgeny	a02c474b94	fix use-after-free in queue_entry_free/dgram_free ordering + add tcp_proxy stress test + proxy diagnostics logging - Fix queue_entry_free before queue_dgram_free in all proxy files (UAF bug causing segfault) - Add PROXY/RP prefixed diagnostic logs for transparent proxy flow tracking - Add tcp_proxy integration test: real utun instances, ETCP, remote_proxy, DNAT routing - 7 test scenarios: basic_1mb, concurrent_5, concurrent_20, half_close, idle, conn_refused, stress (10 threads x 20 iterations) - stress_client.py with --verbose per-thread phase timing (connect/send/recv)	4 months ago
Evgeny	a0e5446790	migrate NAT and DATA to etcp_router, fix warnings and destroy order	5 months ago
Evgeny	907ef244c6	NAT: Full Cone (EIM) NAT with ETCP_ID_NAT protocol, per-node routing, and comprehensive test suite - New ETCP protocol ETCP_ID_NAT (0x02) for NAT traffic between nodes - eim_nat.c/h: Pure NAT engine (table, port allocation, checksum updates, egress/ingress) - nat_transport.c/h: Transport layer (NAT TUN, ETCP binding, client/provider roles) - route_bgp_find_conn_for_node(): shared utility for optimal connection lookup - tun_init_nat(): dedicated TUN creation for NAT - Config: [nat] section with tun_ip, port_start/end, nat_via, forward rules - Fix: csum_update_ip/transport use htonl() halves (correct on LE systems) - Fix: IP_FRAG_MF_MASK changed to 0x2000 (after ntohs, MF is bit 13) - Tests: 26 engine unit + 4 transport integration + 7 stress (29 total)	5 months ago
