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
optimizes the NetBird client startup process by avoiding unnecessary login commands when the peer is already authenticated. The changes increase the default login timeout and expand the log message patterns used to detect successful authentication.
- Increased default login timeout from 1 to 5 seconds for more reliable authentication detection
- Enhanced log pattern matching to detect both registration and ready states
- Added extended regex support for more flexible pattern matching
- 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
DNS record filtering to only include peers that a peer can connect to, reducing unnecessary DNS data in the peer's network map.
- Adds a new `filterZoneRecordsForPeers` function to filter DNS records based on peer connectivity
- Modifies `GetPeerNetworkMap` to use filtered DNS records instead of all records in the custom zone
- Includes comprehensive test coverage for the new filtering functionality
The client status is not enough to protect the RPC calls from concurrency issues, because it is handled internally in the client in an asynchronous way.
Deduplicate STUN package sending.
Originally, because every peer shared the same UDP address, the library could not distinguish which STUN message was associated with which candidate. As a result, the Pion library responded from all candidates for every STUN message.
* Remove aur support and start service on ostree
The aur installation was adding many packages and installing more than just the client. For now is best to remove it and rely on binary install
Some users complained about ostree installation not starting the client, we add two explicit commands to it
* use ${SUDO}
* fix if closure
