Host-socket egress (UDP/ICMP), SOCKS5/HTTP-CONNECT tunnels, and inbound L2 relay for the ArcBox proxy datapath
Documentation

Proxy egress and inbound relay for the ArcBox datapath.

Transport-agnostic building blocks that turn classified guest/host frames into real network I/O, with no VM/VirtIO/device dependency:

  • [socks5] — all SOCKS5 (RFC 1928): the shared address codec, the CONNECT tunnel client ([socks5::connect_via_socks5]), and the UDP-ASSOCIATE client ([socks5::Socks5UdpAssociation]), connecting by hostname so Fake-IP destinations resolve on the proxy's side.
  • [http_connect] — the HTTP CONNECT tunnel client.
  • [egress] — proxies guest UDP/ICMP through real host sockets (bypassing kernel routing / VPN interference), optionally via the SOCKS5 proxy, and dispatches inbound datagrams through the [inbound_relay].
  • [inbound_relay] — host → guest port forwarding by injecting crafted L2 frames, plus the listener manager and InboundCommand channel.

Extracted from arcbox-net so a host-level proxy can reuse the same egress and relay machinery as the VM datapath.
