Add ConnectionRateLimiter (HashMap<IpAddr, usize>) and AuthAttemptLimiter
with check/on_connect/on_disconnect and check/on_failure methods.
Integrate into ServerHandler with structured tracing::info! logging for
auth attempts, connection opened/closed events. No logging of tunnel
destinations per ADR-006. Also add ForwardError type and fix type
annotation in forward.rs to unblock compilation.
Add AcmeCertProvider with domain-based and IP-based modes using rustls-acme.
AcmeTlsAcceptor::bind_acme() and TlsAcceptor::bind_acme() provide ACME-integrated
TLS acceptance with automatic cert renewal via background tokio task.
Feature-gated behind 'acme' (implies 'tls'). Unit tests for config construction;
integration test for LE staging marked #[ignore].
Convert socks5.rs to directory module with protocol parsing and server
implementation. Socks5Server binds to configurable address (default
127.0.0.1:1080), handles SOCKS5 handshake (no-auth), parses IPv4/IPv6/domain
addresses, and proxies bidirectionally via SSH direct_tcpip channels.
Domain names sent unresolved (SOCKS5h) to prevent DNS leaks (ADR-006).
No logging of request targets per privacy requirements.
Add iroh QUIC P2P transport using tokio::io::join for stream duplexing
per ADR-003. Default relay is n0's https://relay.iroh.network/ (ADR-009).
Proxy URL passed to Endpoint::builder (ADR-010). Integration test marked
#[ignore] for CI since it requires iroh relay connectivity.
Address 5 critical and 7 warning issues from architecture review:
- Fix duplicate sentence in napi-and-pubsub.md server side section
- Add wraith- namespace reservation to server.md constraints (ADR-018)
- Document stealth mode TLS-only requirement in server.md
- Create ADR-019 for --proxy dual semantics (client vs server)
- Clarify NAPI connect() vs CLI wraith connect distinction
- Add SOCKS5h default as privacy design decision in client.md
- Expand reconnection section (always-on, re-register port forwards)
- Add graceful shutdown sections to client.md and server.md
- Specify OpenSSH key format for path-or-buffer inputs across all docs
- Resolve pubsub alternative approach ambiguity (ADR-018 is primary)
- Replace server.md handler impl block with behavioral description
- Standardize iroh endpoint ID terminology (base58-encoded)
- Remove iroh API implementation details from transport.md/server.md
- Add error handling pattern as cross-cutting concern in overview.md
- Update all document statuses from draft to reviewed
