Reset client management grpc client backoff after successful connected to management API.
Current Situation:
If the connection duration exceeds MaxElapsedTime, when the connection is interrupted, the backoff fails immediately due to timeout and does not actually perform a retry.
* Add OAuth select_account prompt support to PKCE flow
Extends LoginFlag enum with select_account options to enable
multi-account selection during authentication. This allows users
to choose which account to use when multiple accounts have active
sessions with the identity provider.
The new flags are backward compatible - existing LoginFlag values
(0=prompt login, 1=max_age=0) retain their original behavior.
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.
- Port dnat changes from https://github.com/netbirdio/netbird/pull/4015 (nftables/iptables/userspace)
- For userspace: rewrite the original port to the target port
- Remember original destination port in conntrack
- Rewrite the source port back to the original port for replies
- Redirect incoming port 5353 to 22054 (tcp/udp)
- Revert port changes based on the network map received from management
- Adjust tracer to show NAT stages
makes the DNS forwarder port configurable in the management and client components, while changing the well-known port from 5454 to 22054. The change includes version-aware port assignment to ensure backward compatibility.
- Adds a configurable `ForwarderPort` field to the DNS configuration protocol
- Implements version-based port computation that returns the new port (22054) only when all peers support version 0.59.0 or newer
- Updates the client to dynamically restart the DNS forwarder when the port changes
This PR improves the NetBird client's status checking mechanism by implementing earlier detection of client state changes and better handling of connection lifecycle management. The key improvements focus on:
• Enhanced status detection - Added waitForReady option to StatusRequest for improved client status handling
• Better connection management - Improved context handling for signal and management gRPC connections• Reduced connection timeouts - Increased gRPC dial timeout from 3 to 10 seconds for better reliability
• Cleaner error handling - Enhanced error propagation and context cancellation in retry loops
Key Changes
Core Status Improvements:
- Added waitForReady optional field to StatusRequest proto (daemon.proto:190)
- Enhanced status checking logic to detect client state changes earlier in the connection process
- Improved handling of client permanent exit scenarios from retry loops
Connection & Context Management:
- Fixed context cancellation in management and signal client retry mechanisms
- Added proper context propagation for Login operations
- Enhanced gRPC connection handling with better timeout management
Error Handling & Cleanup:
- Moved feedback channels to upper layers for better separation of concerns
- Improved error handling patterns throughout the client server implementation
- Fixed synchronization issues and removed debug logging
- 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 PR adds user approval functionality to the management system, allowing administrators to manually approve new users joining via domain matching. When enabled, users are blocked with pending approval status until explicitly approved by an admin.
Adds UserApprovalRequired setting to control manual user approval requirement
Introduces user approval and rejection endpoints with corresponding business logic
Prevents pending approval users from adding peers or logging in
In this PR, speed up the GRPC message processing, force the recreation of the ICE agent when getting a new, remote offer (do not wait for local STUN timeout).
The health check endpoint listens on a dedicated HTTP server.
By default, it is available at 0.0.0.0:9000/health. This can be configured using the --health-listen-address flag.
The results are cached for 3 seconds to avoid excessive calls.
The health check performs the following:
Checks the number of active listeners.
Validates each listener via WebSocket and QUIC dials, including TLS certificate verification.
