Three tasks implementing ADR-027:
1. core/rawkey-decouple-from-iroh: TlsIdentity::RawKey now uses
Ed25519SecretKey (alknet-core-owned wrapper over ed25519_dalek)
instead of iroh::SecretKey. RawKeyCertResolver and Ed25519SigningKey
un-gated from #[cfg(all(quinn, iroh))] to #[cfg(quinn)] only.
Quinn-only builds (default) now support RFC 7250 raw-key identity.
iroh transport converts via iroh::SecretKey::from_bytes.
2. core/endpoint-request-client-cert: replaced with_no_client_auth()
with AcceptAnyCertVerifier — a custom ClientCertVerifier that
requests client certs but doesn't require them or verify against
a CA. alknet's identity model is fingerprint-based (the
authorized_fingerprints set is the trust anchor), not PKI-based.
Peer certs are extracted at the TLS layer for fingerprinting;
peers without certs connect normally.
3. core/acme-integration: TlsIdentity::Acme variant (domains,
cache_dir, directory, contact) + AcmeDirectory enum. TlsSetup
two-phase construction: synchronous for X509/RawKey/SelfSigned,
async for Acme (spawns AcmeState event loop, builds ServerConfig
with ResolvesServerCertAcme). acme-tls/1 ALPN added when ACME is
active; dispatch_quinn guard closes challenge connections
gracefully (challenge is TLS-layer-handled). acme feature gate
keeps rustls-acme out of non-ACME builds.
Workspace: build/test/clippy green across all 3 feature configs
(quinn-only, quinn+iroh, quinn+acme, all-features). 331 tests, 0
failures, 0 warnings.
Implements the foundational types in alknet-core/src/types.rs per the
core-types architecture (ADRs 002, 007, 014, 022):
- ProtocolHandler trait (alpn + async handle) with HandlerError
- Connection wrapping quinn/iroh via internal enum dispatch (feature-gated);
write-once identity via OnceLock, IdentityAlreadySet on second set
- SendStream/RecvStream concrete wrappers implementing AsyncWrite/AsyncRead
- BiStream convenience trait
- StreamError with canonical From<StreamError> for HandlerError
- Capabilities: non-serializable, Zeroize + ZeroizeOnDrop, immutable builder
API (new/with_api_key/with_http_token/get) backed by a Secret<String> wrapper
- Minimal Identity and AuthContext in auth.rs as the foundation the auth task
extends
13 unit tests cover Capabilities (build/get/clone/zeroize/redaction) and
Connection::set_identity (once succeeds, twice errors). Verified across
feature combos (default, no-default, iroh-only): build, clippy -D warnings,
test, fmt --check all clean.
(task: core/core-types)
Create crates/alknet-core with Cargo.toml (dependencies, feature flags
quinn/iroh), src/lib.rs declaring types/auth/config/endpoint modules, and
skeleton files for each module with doc comments and TODO markers. Add the
crate to the workspace members list.
Both quinn (default-on) and iroh (opt-in) are optional and can be active
simultaneously per ADR-010. Dual license MIT OR Apache-2.0 inherited from
the workspace.
Add http feature flag with axum, hyper, hyper-util, tower, and http-body-util
dependencies. Create http module with auth middleware (extracts Bearer token,
calls IdentityProvider::resolve_from_token, attaches Identity to extensions)
and router scaffold (default 404 fallback, no operational routes yet). Replace
send_fake_nginx_404 with axum router handoff when http feature is enabled;
fake 404 behavior preserved when http is disabled. Wire HttpInterface with
build_router() method and pass IdentityProvider through Server to handle_connection.
ConfigServiceImpl wraps ArcSwap<DynamicConfig> providing forwarding_policy(),
rate_limits(), and reload() methods for direct use (always available).
ConfigProtocol enum (GetForwardingPolicy, GetRateLimits, ReloadForwarding,
ReloadRateLimits) is gated behind the irpc feature flag per ADR-030.
Split alknet-core configuration into StaticConfig (immutable after startup)
and DynamicConfig (hot-reloadable at runtime via ArcSwap).
- Add StaticConfig struct in config/static_config.rs with all fields per ADR-030
- Add DynamicConfig struct with AuthPolicy, ForwardingPolicy, RateLimitConfig
- Add ForwardingPolicy with allow_all()/deny_all() defaults (ADR-031)
- Add ConfigReloadHandle with reload() method for runtime config updates
- Replace Arc<ServerAuthConfig> with Arc<ArcSwap<DynamicConfig>> in ServerHandler
- Add config_reload_handle() to Server for obtaining reload handles
- Add AuthPolicy with authenticate_publickey/authenticate_certificate methods
- All existing tests pass with the new config structure
- Default DynamicConfig produces identical behavior to current code
