Per RFC 4592 section 2.2.1, wildcards should only match when the queried
name does not exist in the zone. Previously, if host.example.com had an
A record and *.example.com had an AAAA record, querying AAAA for
host.example.com would incorrectly return the wildcard AAAA instead of
NODATA.
Now the resolver checks if the domain exists (with any record type)
before falling back to wildcard matching, returning proper NODATA
responses for existing names without the requested record type.
* **New Features**
* Wildcard DNS fallback for eligible query types (excluding NS/SOA): attempts wildcard records when no exact match, rewrites wildcard names back to the original query, and rotates responses; preserves CNAME resolution.
* **Tests**
* Vastly expanded coverage for wildcard behaviors, precedence, multi-record round‑robin, multi-type chains, multi-hop and cross-zone scenarios, and edge cases (NXDOMAIN/NODATA, fallthrough).
* **Chores**
* CI lint config updated to ignore an additional codespell entry.
Adds a per-instance uint64 hash to DefaultServer to detect identical merged host DNS configs (including extra domains). applyHostConfig computes and compares the hash, skips applying if unchanged, treats hash errors as a fail-safe (proceed to apply), and updates the stored hash only after successful hashing and apply.
in some cases iOS and macOS may be locked when looking for management domains during network changes
This change introduce an additional timeout on top of the context call
Two new boolean flags, SearchDomainDisabled and SkipPTRProcess, are added to CustomZone and its protobuf; they are propagated through the engine to DNS host logic. Host matching now uses SearchDomainDisabled directly, and PTR collection skips zones with SkipPTRProcess; reverse zones are initialized with SearchDomainDisabled: true.
Upgrade Go toolchain and golang.org/x/* deps to 1.24.10, standardize GitHub Actions to derive Go version from go.mod and adjust checkout ordering, raise WASM size limit to 55 MB, update FreeBSD tarball and gomobile refs, fix a few format-string/logging calls, treat usernames ending with $ as system accounts, and add Windows tests.
- Move `util/grpc` and `util/net` to `client` so `internal` packages can be accessed
- Add methods to return the next best interface after the NetBird interface.
- Use `IP_UNICAST_IF` sock opt to force the outgoing interface for the NetBird `net.Dialer` and `net.ListenerConfig` to avoid routing loops. The interface is picked by the new route lookup method.
- Some refactoring to avoid import cycles
- Old behavior is available through `NB_USE_LEGACY_ROUTING=true` env var
This will allow running netbird commands (including debugging) against the daemon and provide a flow similar to non-container usages.
It will by default both log to file and stderr so it can be handled more uniformly in container-native environments.
With the lazy connection feature, the peer will connect to target peers on-demand. The trigger can be any IP traffic.
This feature can be enabled with the NB_ENABLE_EXPERIMENTAL_LAZY_CONN environment variable.
When the engine receives a network map, it binds a free UDP port for every remote peer, and the system configures WireGuard endpoints for these ports. When traffic appears on a UDP socket, the system removes this listener and starts the peer connection procedure immediately.
Key changes
Fix slow netbird status -d command
Move from engine.go file to conn_mgr.go the peer connection related code
Refactor the iface interface usage and moved interface file next to the engine code
Add new command line flag and UI option to enable feature
The peer.Conn struct is reusable after it has been closed.
Change connection states
Connection states
Idle: The peer is not attempting to establish a connection. This typically means it's in a lazy state or the remote peer is expired.
Connecting: The peer is actively trying to establish a connection. This occurs when the peer has entered an active state and is continuously attempting to reach the remote peer.
Connected: A successful peer-to-peer connection has been established and communication is active.
