Adds support for using a random available WireGuard port when the user specifies port `0`.
- Updates `freePort` logic to bind to the requested port (including `0`) without falling back to the default.
- Removes default port assignment in the configuration path, allowing `0` to propagate.
- Adjusts tests to handle dynamically assigned ports when using `0`.
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.
- 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

Moving code to ensure wgInterface is gone right after context is
cancelled/stop in the off chance that on next retry the backoff
operation is permanently cancelled and interface is abandoned without
destroying.
This update adds new relay integration for NetBird clients. The new relay is based on web sockets and listens on a single port.
- Adds new relay implementation with websocket with single port relaying mechanism
- refactor peer connection logic, allowing upgrade and downgrade from/to P2P connection
- peer connections are faster since it connects first to relay and then upgrades to P2P
- maintains compatibility with old clients by not using the new relay
- updates infrastructure scripts with new relay service
wait on engine down to not only wait for the interface to be down but completely removed. If the waiting loop reaches the timeout we will trigger an interface destroy. On the up command, it now waits until the engine is fully running before sending the response to the CLI. Includes a small refactor of probes to comply with sonar rules about parameter count in the function call
Rely on net.ListenUDP to get an available port for wireguard in case the configured one is in use

* Enable network monitoring by default for Windows and Darwin
* Enable network monitoring by default on Windows and macOS
* fix merge
* Prevent updating config if no changes
* compile client under freebsd (#1620)
Compile netbird client under freebsd and now support netstack and userspace modes.
Refactoring linux specific code to share same code with FreeBSD, move to *_unix.go files.
Not implemented yet:
Kernel mode not supported
DNS probably does not work yet
Routing also probably does not work yet
SSH support did not tested yet
Lack of test environment for freebsd (dedicated VM for github runners under FreeBSD required)
Lack of tests for freebsd specific code
info reporting need to review and also implement, for example OS reported as GENERIC instead of FreeBSD (lack of FreeBSD icon in management interface)
Lack of proper client setup under FreeBSD
Lack of FreeBSD port/package
* Add DNS routes (#1943)
Given domains are resolved periodically and resolved IPs are replaced with the new ones. Unless the flag keep_route is set to true, then only new ones are added.
This option is helpful if there are long-running connections that might still point to old IP addresses from changed DNS records.
* Add process posture check (#1693)
Introduces a process posture check to validate the existence and active status of specific binaries on peer systems. The check ensures that files are present at specified paths, and that corresponding processes are running. This check supports Linux, Windows, and macOS systems.
