evgeny	61c572cae4	etcp: reset_id эпоха ресета — фикс потери NODEINFO при флапе Добавлен 64-битный reset_id (эпоха ресета) в INIT-фреймы и STCP-handshake: - генерится один раз при создании conn, меняется только при фатальном ресете (normalizer desync / bad fragment size); - при приёме чужого id slave принимает эпоху пира и ресетится, master держит свою; - первый id принимается без ресета (свежие при init); - «tcp peer clean» реинит гейтится по смене id — нет повторного сброса seq. Это устраняет коллизию seq=1 (RX dup) из-за двойного реинита нескольких TCP-линков, из-за которой NODEINFO пира терялся и member не возвращался online. Также: chat member online теперь из topo_group (без БД/merkle), тест test_etcp_seq_collision.	4 weeks ago
evgeny	f47ad7d87f	tcp_proxy: fix throughput (tx_queue backpressure) + connect timeout + integration test - Router: unified service delivery format [svc_id][src][dst][payload] (end-to-end src/dst from SVC_ROUTE header) - tcp_proxy_client: replace single tx_buf drop-on-backpressure with bounded tx_queue + send_q waiter + retry timer (no data loss, bulk window reopen — removes 62.5ms delayed-ACK stall) - tcp_io: configurable connect timeout (tcp_conn_set_connect_timeout) - tcp_proxy_server: connect_timeout config option (ms, default 2000, 0=off) - check.sh: run tcp_proxy_full integration test with sudo (skip if passwordless sudo unavailable) - test_tcp_io: connect timeout unit test; docs (lwip_nuances.md)	4 weeks ago

evgeny	f2228202e3	fix: FORTIFY vsnprintf crash on Android + foreground service type Root cause: etcp_on_up/etcp_on_down/etcp_conn_process_send_queue used fixed buffers (links_str[256], l_status[256]) with snprintf chains in loops over links.

evgeny	5e739176fa	media_delivery: fix etcp_route_send svc_id + integration test Root cause: etcp_route_send reads dgram[0] as svc_id, not subcmd. router_deliver prepends svc_id byte on receive. Fixes: - md_send/md_dl_send/msend: prepend ETCP_RT_ID_MEDIA_DELIVERY to dgram[0] - md_etcp_recv: read subcmd from data[1] (was data[0]) - etcp_api.h: document dgram[0]=svc_id convention - media_delivery_set_supernode(): public API for dynamic switching Tests: - test_media_delivery_integration: 4/4 (SERVE_REG, HAVE_BLOCK, supernode stop/start) - All 24 existing tests still pass	2 months ago

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	3 months ago
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.	3 months ago
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	3 months ago
