Now that we have the latency between peers available we can use this data to consider when choosing the best route. This way the route with the routing peer with the lower latency will be preferred over others with the same target network.
* Add Linux legacy routing if ip rule functionality is not available
* Ignore exclusion route errors if host has no route
* Exclude iOS from route manager
* Also retrieve IPv6 routes
* Ignore loopback addresses not being in the main table
* Ignore "not supported" errors on cleanup
* Fix regression in ListenUDP not using fwmarks
All routes are now installed in a custom netbird routing table.
Management and wireguard traffic is now marked with a custom fwmark.
When the mark is present the traffic is routed via the main routing table, bypassing the VPN.
When the mark is absent the traffic is routed via the netbird routing table, if:
- there's no match in the main routing table
- it would match the default route in the routing table
IPv6 traffic is blocked when a default route IPv4 route is configured to avoid leakage.
* adding peer healthcheck
* generate proto file
* fix return in udp mux and replace with continue
* use ice agent for latency checks
* fix status output
* remove some logs
* fix status test
* revert bind and ebpf code
* fix error handling on binding response callback
* extend error handling on binding response callback

* Fix using wrong array index in log to avoid potential panic
* Increase gRPC connection timeout and add the timeout resolv.conf option
This makes sure the dns client is able to failover to a second
configured nameserver, if present. That is the case then when using the
dns `file` manager and a resolv.conf file generated for netbird.
* On file backup restore, remove the first NS if it's the netbird NS
* Bump dns mangager discovery message from debug to info to ease debugging
This changes the default behavior for new peers, by requiring the agent to be executed with allow-server-ssh set to true in order for the management configuration to take effect.
With these changes, the command up supports the flag --disable-auto-connect that allows users to disable auto connection on the client after a computer restart or when the daemon restarts.
This PR implements the following posture checks:
* Agent minimum version allowed
* OS minimum version allowed
* Geo-location based on connection IP
For the geo-based location, we rely on GeoLite2 databases which are free IP geolocation databases. MaxMind was tested and we provide a script that easily allows to download of all necessary files, see infrastructure_files/download-geolite2.sh.
The OpenAPI spec should extensively cover the life cycle of current version posture checks.
* Make sure our iOS dialer does not get overwritten
* set dial timeout for both clients on ios

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.
Ensure we use WG address instead of loopback addresses for eBPF.
- First try to use 53 port
- Try to use 5053 port on WG interface for eBPF
- Try to use 5053 on WG interface or loopback interface
In the case of disabled stub listeren the list of name servers is unordered. The solution is to configure the resolv.conf file directly instead of dbus API.
Because third-party services also can manipulate the DNS settings the agent watch the resolv.conf file and keep it up to date.
- apply file type DNS manager if in the name server list does not exist the 127.0.0.53 address
- watching the resolv.conf file with inotify service and overwrite all the time if the configuration has changed and it invalid
- fix resolv.conf generation algorithm
* 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
