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 - Remove chat_connections — use unified connections queue directly - Update all iteration/search patterns across 40 files (src + tests + chatgui)	3 months ago
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	3 months ago
jeka	7139969acd	fix: Windows/MSYS2 build compatibility - proxy/icmp_proxy.c: define struct icmp/ip + ICMP constants for _WIN32 - lwip_tcp_priv.h: use #include <winsock2.h> instead of #define htonl/htons - lwip_tcp.h/c: rename poll field to pollfn (avoid WSAPoll macro conflict) - tests: guard Unix-only headers with #ifndef _WIN32, skip fork/socketpair tests	3 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	73f707ef9b	crypto: migrate ECDH(secp256r1) to X25519, drop TinyCrypt - SC_PUBKEY_SIZE: 64 -> 32 bytes, SC_PUBKEY_ENC_SIZE: 72 -> 40 - sc_set_peer_public_key uses EVP_PKEY_derive with X25519 - sc_generate_keypair via EVP_PKEY_keygen(EVP_PKEY_X25519) - sc_compute_public_key_from_private via EVP_PKEY_new_raw_private_key - sc_validate_key: check non-zero (X25519 has no invalid keys) - sc_obfuscate_pubkey: XOR now 32 bytes - Remove all TinyCrypt code (~860 lines), always use OpenSSL - Remove TinyCrypt from build system, drop test_crypto/test_ecc_encrypt - Update all test keys (128 hex -> 64 hex) - Fix bbr_integration.c split-line pubkeys	4 months ago
Evgeny	0dd942be63	fix: стабилизация тестов test_tcp_io и test_bbr_integration - test_bbr_integration: bbr_max_cwnd=100KB (16×BDP) — устранён overshoot очереди - test_tcp_io: адаптирован под EPOLLHUP на socketpair (send до poll, error_cb вместо fin) - tcp_io: расширенная диагностика error_cb с состоянием сокета	4 months ago
Evgeny	075c4f4583	memory_pool: name field — идентификация пула в диагностике коррапшна	4 months ago
Evgeny	2a259191b9	feat: queue_set_waiter_defer — immediate or call_soon callback mode queue_waiter_handle stores defer_q/cb/arg, no extra malloc. queue_set_waiter_defer(q, 1) enables call_soon dispatch for waiter callbacks. bbr_integration uses it instead of manual send_waiter_cb wrapper.	4 months ago
Evgeny	331d43c6f7	fix: proxy ERROR loop, BBR test backpressure, O(1) u_free, test ordering - tcp_proxy: ERROR silently dropped (no ERROR->ERROR loop), Russian removed from logs - etcp_bbr: swap min(lo) and max(4mss) in bbr_bound_cwnd_for_inflight_model - test_etcp_bbr: fix cwnd comparison (packets vs bytes) - ll_queue: double-put detection (abort), Floyd cycle detection in consistency check - ll_queue: QUEUE_DEBUG commented out (was always-on, O(N) per put) - mem: u_free_impl now O(1) via doubly-linked list, double-free detection - bbr_integration: queue_waiter_wait + call_soon backpressure (threshold=1) - tests/Makefile.am: fast tests first, .log cleanup before run	4 months ago
Evgeny	0adff0253d	bbr: исправить отображение сырых BW-значений (bw_latest/bw_lo/bw_hi) с /125 на /2097 BW_RAW_TO_KBPS = bw_raw * 8000 / BW_UNIT = bw_raw / 2097.152 pacing_rate / 125 остаётся без изменений (уже в bytes/sec после bbr_rate_bytes_per_sec)	4 months ago
Evgeny	4f0baa37db	bbr: исправить передачу потерь в BBR + пол для cwnd на уровне BBR_CWND_MIN_TARGETmss - etcp.c: rs->lost из link->bbr_loss_since_ack (был хардкод 0), вызов bbr_note_loss при ретрансмите - etcp_connections.h: поле bbr_loss_since_ack для per-link учёта потерь в байтах - etcp_bbr.c: везде где BBR_CWND_MIN_TARGET — умножить на mss (юнит-мизматч пакеты/байты) - bbr_quantization_budget, bbr_set_cwnd, bbr_bound_cwnd_for_inflight_model, bbr_probe_rtt_cwnd - bbr_init_lower_bounds: инициализация inflight_hi из cwnd (был ~0U навсегда) - control_server.c + etcpmon: экспорт BBR-метрик (bw_hi/lo, inflight_hi/lo, режим, потери) - tests/bbr_integration: интеграционный тест BBR (15с, 50ms/5%loss/1Mbit) с таблицей метрик - устранён death spiral BBR при высоких потерях: cwnd теперь не падает ниже 4mss	4 months ago
