enhances debugging capabilities by adding support for goroutine, mutex, and block profiling while updating state dump tracking and refining test and release settings.
- Adds pprof-based profiling for goroutine, mutex, and block profiles in the debug bundle.
- Updates state dump functionality by incorporating new status and key fields.
- Adjusts test validations and default flag/retention settings.
adds NetFlow functionality to track and log network traffic information between peers, with features including:
- Flow logging for TCP, UDP, and ICMP traffic
- Integration with connection tracking system
- Resource ID tracking in NetFlow events
- DNS and exit node collection configuration
- Flow API and Redis cache in management
- Memory-based flow storage implementation
- Kernel conntrack counters and userspace counters
- TCP state machine improvements for more accurate tracking
- Migration from net.IP to netip.Addr in the userspace firewall
- Refactor the network monitoring to handle one event and it after return
- In the engine restart cancel the upper layer context and the responsibility of the engine stop will be the upper layer
- Before triggering a restart, the engine checks whether the state is already down. This helps avoid unnecessary delayed network restart events.
The "runningChan" provides feedback to the UI or any client about whether the service is up and running. If the client exits earlier than when the service successfully starts, then this channel causes a block.
- Added timeout for reading the channel to ensure we don't cause blocks for too long for the caller
- Modified channel writing operations to be non-blocking
- When a peer is connected with TURN and a Relay connection is established, do not force switching to Relay. Keep using TURN until disconnection.
-In the proxy preparation phase, the Bind Proxy does not set the remote conn as a fake address for Bind. When running the Work() function, the proper proxy instance updates the conn inside the Bind.
