* Fix Relay disconnection handling
If has an active P2P connection meanwhile the Relay connection broken with the server then we removed the WireGuard peer configuration.
* Change logs
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
* 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.

sends an extra server reflexive candidate to the remote peer with our related port (usually the Wireguard port)
this is useful when a network has an existing port forwarding rule for the Wireguard port and the local peer and avoids creating a 1:1 NAT on the local network.
* Adds management, signal, and relay (STUN/TURN) health probes to the status command.
* Adds a reason when the management or signal connections are disconnected.
* Adds last wireguard handshake and received/sent bytes per peer
This PR aims to integrate Rosenpass with NetBird. It adds a manager for Rosenpass that starts a Rosenpass server and handles the managed peers. It uses the cunicu/go-rosenpass implementation. Rosenpass will then negotiate a pre-shared key every 2 minutes and apply it to the wireguard connection.
The Feature can be enabled by setting a flag during the netbird up --enable-rosenpass command.
If two peers are both support and have the Rosenpass feature enabled they will create a post-quantum secure connection. If one of the peers or both don't have this feature enabled or are running an older version that does not have this feature yet, the NetBird client will fall back to a plain Wireguard connection without pre-shared keys for those connections (keeping Rosenpass negotiation for the rest).
Additionally, this PR includes an update of all Github Actions workflows to use go version 1.21.0 as this is a requirement for the integration.

In case of 'always-on' feature has switched on, after the reboot the service do not start properly in all cases.
If the device is in offline state (no internet connection) the auth login steps will fail and the service will stop.
For the auth steps make no sense in this case because if the OS start the service we do not have option for
the user interaction.
EBPF proxy between TURN (relay) and WireGuard to reduce number of used ports used by the NetBird agent.
- Separate the wg configuration from the proxy logic
- In case if eBPF type proxy has only one single proxy instance
- In case if the eBPF is not supported fallback to the original proxy Implementation
Between the signature of eBPF type proxy and original proxy has
differences so this is why the factory structure exists
Reduce the peer status notifications
When receive new network map invoke multiple notifications for
every single peers. It cause high cpu usage We handle the in a
batch the peer notification in update network map.
- Remove the unnecessary UpdatePeerFQDN calls in addNewPeer
- Fix notification in RemovePeer function
- Involve FinishPeerListModifications logic
Prevent peer updates if the status is not changing from disconnected to connected and vice versa.
Fixed route score calculation, added tests and changed the log message
fixed installer /usr/local/bin creation
This PR brings support of a shared port between stun (ICE agent) and
the kernel WireGuard
It implements a single port mode for execution with kernel WireGuard
interface using a raw socket listener.
BPF filters ensure that only STUN packets hit the NetBird userspace app
Removed a lot of the proxy logic and direct mode exchange.
Now we are doing an extra hole punch to the remote WireGuard
port for best-effort cases and support to old client's direct mode.
This PR adds supports for the WireGuard userspace implementation
using Bind interface from wireguard-go.
The newly introduced ICEBind struct implements Bind with UDPMux-based
structs from pion/ice to handle hole punching using ICE.
The core implementation was taken from StdBind of wireguard-go.
The result is a single WireGuard port that is used for host and server reflexive candidates.
Relay candidates are still handled separately and will be integrated in the following PRs.
ICEBind checks the incoming packets for being STUN or WireGuard ones
and routes them to UDPMux (to handle hole punching) or to WireGuard respectively.
Refactored updateServerStates and calculateState
added some checks to ensure we are not sending connecting on context canceled
removed some state updates from the RunClient function
