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

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)

Evgeny fcf3fb7f51 refactor: move transport (etcp/stcp/normalizer) to transport_layer/, routing (bgp/pings/topo*) to routing_layer/ 2026-07-21 20:25:41 +03:00
Evgeny 93871c592b db_sync: timeout for stuck sync_state=1, handle ERROR properly 
- Add sync_start_tb to SI_PEER, set in db_sync_initiate_sync
- peer_check_cb: after 15s timeout reset sync_state=0 with WARN
- db_handle_error: accept si, reset sync_state=0, DEBUG_ERROR with details
- DB_SYNC_SYNC_TIMEOUT=15 added to db_sync.h

Evgeny 3d04c37f56 stcp: add on_close callback to stcp_server_create/stcp_client_connect; member_sync: add join_ts/update_sig/update_ts fields, verify update_sig in apply; topo_node_sqlite: add join_ts/update_sig/update_ts to member_put, add member_get_join, add node_update_verified; chat_sync: include join_ts in join_msg, add update_sig/update_ts to CHANNEL_INFO_RESP; WELCOME verify join_sig; tests: use generated node_ids, reduce max ticks 2026-07-16 19:04:00 +03:00
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)

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

Evgeny ba14e31e09 fix: remove retry_timer, use waiter-based round-robin on send_q for fairness 
- tcp_proxy_server: drain_cb uses etcp_router_on_send_ready instead of retry_timer
- socks_proxy: on_read_cb + tx_waiter_cb use etcp_router_on_send_ready instead of waiter_register
- Result: FIFO round-robin via ll_queue waiters on send_q, all streams get fair share
- No timers — wakeup is event-driven via queue_data_get → check_waiters
- TCP backpressure: read_queue callback_suspended prevents over-reading

Evgeny 5b850ea5da test: add profiling (MB/s per file per worker) to socks_http_proxy 2026-07-03 15:54:09 +03:00
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

Evgeny 2cb85cbc3d socks_proxy: поддержка HTTP-прокси (GET/POST/HEAD/OPTIONS/...) — не только CONNECT 
process_http_request() теперь обрабатывает любые HTTP-методы:
- CONNECT — туннель как раньше, без изменений
- GET/POST/PUT/HEAD/OPTIONS/... — парсинг абсолютного URL, DNS,
  send_connect + пересборка строки с относительным путём + тело DATA

test_socks_http_proxy: +3-й worker (http_proxy через -x без --proxytunnel),
+проверки POST (echo), HEAD (200 OK), OPTIONS (Allow). Все 78 проверок — PASS.
 2026-07-02 22:04:37 +03:00
Evgeny de8cce521a all 51 tests pass: fd=0 protection + clean socks_http_proxy test 
- socket_compat: never close fd=0
- socks_http_proxy: rewritten cleanly, 2 workers, 25 reqs each, up to 100KB
- uasync_socket_race: dup2-based fd=0 reservation
- u_async: removed DIAG spam
- tcp_io: removed debug fprintf

Result: 51/51 tests pass.

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
