Adds Relay.HasURLs/AllURLs helpers so all relay-enabled checks use the
same definition ("any URL is configured, regardless of whether it came
from Addresses or Endpoints"), and a Normalize step run at startup that:
- Drops unknown transport identifiers (anything outside ws/quic/wt),
reporting them via a warning log so misconfigurations surface loudly
instead of being silently advertised to clients.
- De-duplicates endpoint URLs and per-endpoint transports.
- Preserves empty Transports lists — that's the valid "unknown, let the
client try whatever it supports" signal, distinct from a typo'd list.
The two relay-token guard sites in server.go switch to HasURLs so a
deployment with only Endpoints (no Addresses) actually issues tokens;
before this change those branches would skip token generation. The
startup log now prints the merged URL list plus per-endpoint transport
hints, matching what clients will receive.
Two follow-ups to the WebTransport/ALPN-mux landing:
Deployment templates publish UDP alongside TCP for the relay so the
single ALPN-multiplexed socket can serve raw QUIC and WebTransport
clients on the same port as the existing WebSocket transport.
- docker-compose.yml.tmpl: adds the matching `/udp` mapping; the relay
was already binding both stacks, the host port just wasn't published.
- docker-compose.yml.tmpl.traefik: WebTransport is the awkward case —
Traefik can't proxy WT sessions, so the relay container now publishes
UDP/443 directly and obtains its own Let's Encrypt cert (separate
volume), while the TCP /relay route stays behind Traefik unchanged so
WS-only clients keep working.
Management server learned to advertise per-relay transport hints:
- Config gains an optional `Endpoints []{URL, Transports}` block on the
Relay section, mirrored to clients as RelayConfig.endpoints.
- `Addresses` is still emitted as RelayConfig.urls so older agents keep
working unchanged.
- A single BuildRelayConfigProto helper is the only place that builds
the proto, called from both toNetbirdConfig and the token push paths.
The GeoDNS case is operator-asserted, not probed: a single URL fans out
to several physical relays, and the Transports list must already be the
intersection of what every backend supports. Documented on the config
struct — if any backend behind a hostname can't speak h3, the operator
drops "wt" from that hostname's list and no client tries it there.
Embed Dex as a built-in IdP to simplify self-hosting setup.
Adds an embedded OIDC Identity Provider (Dex) with local user management and optional external IdP connectors (Google/GitHub/OIDC/SAML), plus device-auth flow for CLI login. Introduces instance onboarding/setup endpoints (including owner creation), field-level encryption for sensitive user data, a streamlined self-hosting provisioning script, and expanded APIs + test coverage for IdP management.
