evgeny	21ec740d82	socks_proxy: defer conn free to fix UAF from synchronous write_queue flush	2 weeks ago
evgeny	fbea9c3869	socks_proxy: fix client stall + non-blocking DNS via async_dns - fix HTTP_STATE_RELAY == SOCKS_STATE_CONNECTING enum collision (relay data dropped) - fix wrong waiter cancel (etcp_router_waiter_cancel -> etcp_router_cancel_send_ready) - add backpressure retry timer, restore lost queue_resume_callback, defer FIN on pending tx_buf - async_dns: /etc/hosts fast-path + hosts loading (avoid 4s DNS timeout for localhost)	4 weeks ago
evgeny	38c9f229bc	stcp: ed25519 pubkey exchange in handshake, fix instance destroy segfault, fix chat_tcp_test - 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	2 months ago
evgeny	d773f1724a	refactor: STCP connections as ETCP links (is_tcp) - Add is_tcp, tcp_link, tcp_reconnect_* fields to ETCP_LINK - Remove transport_link from ETCP_CONN, add tcp_link_count - stcp_link: replace embedded etcp_conn with pointer; add etcp_link backpointer - stcp_link: link_rx_cb routes ETCP data to etcp_conn_input - stcp_link: call on_close_cb in close - New TCP functions: etcp_link_enter_ready_tcp, etcp_tcp_link_start_connect, etcp_tcp_link_start_reconnect, tcp_link_close_cb, etcp_tcp_send - etcp_link_new: handle NULL conn for TCP links; skip enter_init for TCP - etcp_link_close: close stcp_link for TCP - etcp_encrypt_send: redirect TCP to etcp_tcp_send (skips AES-CCM) - tcp_server_on_link: create ETCP_LINK(is_tcp=1) + enter_ready_tcp - etcp_connect: TCP addrs -> etcp_tcp_link_start_connect - Remove ctx->tcp_link/tcp_ready - test_stcp_traffic: find stcp_link via links->is_tcp instead of transport_link - 66/68 tests pass; 2 STCP tests expected to fail (integration not complete)	2 months ago
Evgeny	797c0736a7	headers: add extern "C" guards for C++ interop (chatgui) Added #ifdef __cplusplus / extern "C" { ... } / #endif to ~65 headers in src/ and lib/, enabling the C library to be linked into C++ code (chatgui). Fixed packet_dump.h (added missing header guard) and etcp_bbr.h (#pragma once guard).	3 months ago
Evgeny	2fba5c31c4	fix: backpressure data loss in socks/http proxy + comprehensive test socks_proxy (client side): - tx_buf buffering on send_data failure in RELAY path, retry in tx_waiter_cb - process_http_request: version_str null-term fix (memcpy(vlen)+explicit \0) - process_http_request: assemble hdr+body+extra into heap pkt, atomic send - socks_proxy_handle_etcp: alloc failure logs write_queue state + byte counters tcp_proxy_server (exit node): - read_queue_drain_cb: tx_buf buffering on backpressure, retry_timer (500ms, force=1) - on_fin_cb: defer FIN when read_queue+tx_buf has pending data (dst_fin_deferred) - handle_data + drain_cb: per-stream byte counters (sent/recv/relayed/drain_count) - on_fin_cb/on_error_cb: detailed state logging (counters, queues, buffers) test_socks_http_proxy: - 4 workers: socks_ipv4, socks_domain (DNS resolution via SOCKS), http_proxy, https_connect - 4 file sizes: 1KB, 100KB, 1MB, 10MB — deterministic content, byte-by-byte cmp -s - HTTPS server with self-signed cert, POST/echo, HEAD, OPTIONS - 51/51 tests PASS	3 months ago
Evgeny	7d460ca156	fix: ASAN-detected UAFs and buffer overflows across 6 modules - etcp_connections: fix link leak & UAF in etcp_socket_remove — remove_link inside etcp_link_close shifts array, skip NULL set and i++ - stcp_server: fix UAF in stcp_conn_process_recv — defer free via uasync_call_soon after stcp_conn_do_close - etcp: save pkt_len before queue_data_put to output_queue (callback may free entry synchronously) - socks_proxy: add pool bounds check before memcpy, UINT16_MAX truncation guard, freed flag - tcp_proxy_server: reorder cleanup (cancel waiters before tcp_conn_destroy), UINT16_MAX guard - test_route6_lib: increase nodes[] array to STRESS_NODES + STRESS_OPS	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
