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	6c2aeb69a1	fix INIT bounds checks and eim_nat port uint16_t wrap	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)	6 months ago
