Evgeny	13d469d866	add orig_src_ip to ICMP proxy protocol, fix deliver_reply dst_ip (was wrong tun_ip_addr)	5 months ago
Evgeny	02c7153822	add icmp_proxy diagnostic logging on all reply path stages	5 months ago
Evgeny	07540b7ff8	fix icmp: use SOCK_RAW for FreeBSD compat, add socket diagnostic logging	5 months ago
Evgeny	edeb83ce89	replace fake ICMP echo reply with test_loopback flag, honest error when no raw socket	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
