jeka/utun2 - utun2 - Gitea: Git with a cup of tea

Author	SHA1	Message	Date
Evgeny	e5d11ef9c1	refactor tcp_proxy: remove local socket mode, simplify architecture - remove sock_transport, transport abstraction, active connections API - simplify proxy_conn to 13 fields (was 15), remove tcp_proxy_mapping linked list - new protocol: stream_id 4B, seq 2B cyclic, HDR_SIZE 8B - add ERROR subcmd for immediate abort, CLOSE for graceful half-close - proper half-close: shutdown SHUT_WR, keep reading, no timer - exhaustive DEBUG_ERROR/WARN on all error/unusual branches - config parser: report unknown options with filename:line and valid keys	4 months ago
Evgeny	cec736a4b0	redesign TCP close: closing_tun/closing_rem flags, poll-driven cleanup, proper half-close	5 months ago
Evgeny	d3b6057f82	add framed read for raw fd (2-byte len prefix), TCP_NODELAY, fix test half-close ordering	5 months ago
Evgeny	ad8bc0ae00	fix lwip_tcp port byte order (double-htons), mapping lookup, socket error handling - Fix port encoding: PCB stores ports in host byte order, tcp_create_segment uses htons - Fix tcp_bind/tcp_connect: ntohs incoming network-order ports - Fix demux comparisons: use host-order sport/dport statics instead of in-place ntohs - Fix tcp_output_alloc_header_common: htons for port output - Add static sport/dport variables (host byte order) to avoid tcphdr corruption - Fix sock_transport_error_callback: handle EPOLLERR during non-blocking connect - Fix mapping local_port: store host-order port for find_mapping_by_port - Fix tcp_proxy_raw_read/tun_input: use IP total length for packet boundaries - test_tcp_proxy: reduce size to 2KB, fix port, add debug_init, add echo server log - test_tcp_proxy handshake and basic data flow now working (known: cwnd/poll throughput tuning needed)	5 months ago
Evgeny	c05e1c9991	replace uIP with adapted lwIP TCP stack (lwip_tcp) - Replace uIP (src/uip/) with adapted lwIP 2.1.x TCP module - Remove original src/lwip/ (replaced by src/lwip_tcp/) - New src/lwip_tcp/ module: lwip_pbuf, lwip_tcp core/in/out - Full TCP state machine, sliding window, congestion control - Fast retransmit/recovery, Van Jacobson RTT estimation - Nagle algorithm (TF_NODELAY), delayed ACK - OOSEQ reassembly, TIME-WAIT handling - Memory: memory_pool for PCB, listen PCB, tcp_seg - Timers: uasync periodic timer drives fast/slow timers - Output: callback-based IP packet output (TUN/raw-fd) - Error codes: LERR_ prefix to avoid conflicts - pbuf: simplified PBUF_RAM with proper header space reservation - Integrate into tcp_proxy.c/h with per-pcb callbacks - Active connection API: struct proxy_conn* instead of int conn_idx - Makefile: remove uip, add lwip_tcp files - test_tcp_proxy updated for new API; test_tcp_proxy_remote disabled - Known: test_tcp_proxy data transfer needs flow tuning (WIP)	5 months ago
Evgeny	a6311a17d0	add UDP/ICMP proxy, refactor tcp_proxy via_node to instance-level - UDP proxy: datagram relay client↔exit over ETCP - ICMP proxy: echo ping relay client↔exit over ETCP - Move via_node_id from per-forward-mapping to global tcp_proxy setting - Support multiple concurrent tcp_proxy instances (no singleton g_tcp_proxy) - Cap handshake padding to stay within 1472+overhead - Handle non-TCP packets (UDP/ICMP) in tcp_proxy raw/tun input paths - Add utun_instance_create_from_str() for test config creation	5 months ago
Evgeny	075d97a459	fix .gitignore: stop ignoring test_*.c source files; add missing test_ipv6_sockets, test_tcp_proxy, test_radix, test_route6_lib sources	5 months ago
