ddidderr be9596c188 feat(relay): add runtime CLI config
Replace the placeholder relay binary with a typed command-line configuration
entry point. This gives the future QUIC server loop the listen endpoint and room
limit configuration it needs without mixing command parsing into networking or
room-state code.

The relay now accepts --listen as either a socket address or an explicit UDP
shorthand such as 443/udp, defaults to 0.0.0.0:443/udp, and validates that the
per-room client limit is positive. The binary currently reports the parsed
configuration and clearly states that the QUIC server loop is not wired yet, so
this commit does not pretend to provide a working relay.

Test Plan:
- cargo fmt --check
- cargo test --workspace
- cargo clippy --workspace --all-targets -- -D warnings
- cargo run -p lanparty-relay -- --listen 443/udp

softlan-vpn

Monorepo for a Layer 2 over QUIC LAN party bridge.

Workspace crates

  • lanparty-proto: shared frame format, MAC validation, MTU helpers.
  • lanparty-ctrl: control-plane messages (join/hello/role/version).
  • lanparty-obs: shared diagnostics/logging event models.
  • lanparty-client-core: platform-agnostic client session state.
  • lanparty-client-win: Windows TAP + route/metric handling binary.
  • lanparty-gateway: Linux AF_PACKET gateway binary.
  • lanparty-relay: public QUIC relay binary.

lanparty-proto

Transport-agnostic tunnel contract shared by all binaries:

  • overlay datagram header encoding and decoding
  • Ethernet frame header parsing
  • MAC address parsing and identity validation
  • QUIC datagram to TAP MTU budget helpers

lanparty-ctrl

Reliable control-plane schema shared by the QUIC stream handlers:

  • endpoint hello messages with role, room, MAC, and datagram budget
  • server welcome, reject, peer lifecycle, stats, and disconnect messages
  • room-code, role/MAC, peer-id, and effective-MTU validation
  • length-prefixed JSON control frames for reliable QUIC streams

lanparty-obs

Shared diagnostics and structured logging vocabulary:

  • gateway/relay frame logs with MACs, ethertype, length, peer, and action
  • tunnel counters shared by control messages and runtime diagnostics
  • client connectivity/TAP diagnostics and user-facing status messages

lanparty-relay

Public relay binary and relay-owned room state:

  • room admission for clients and gateways
  • one gateway per room, duplicate client MAC rejection, and room limits
  • stable effective room MTU chosen before Ethernet datagrams flow
  • Ethernet datagram forwarding decisions with no ingress reflection

Build

cargo check --workspace

Relay

cargo run -p lanparty-relay -- --listen 443/udp

--listen accepts either a socket address or a UDP port shorthand such as 443/udp. The relay QUIC server loop is not wired yet.
