Fixes panic occurring when body is nil (this usually happens when connections is refused) due to lack of nil check by centralizing response.Body.Close() behavior.
When a gRPC error occurs in the Flow package, it will be propagated to the upper layers and handled similarly to a Management gRPC error.
Always report a disconnected state in the event of any error
Hide the underlying gRPC errors
Force close the gRPC connection in the event of any error
This PR fixes configuration inconsistencies and updates the store engine type usage throughout the management code. Key changes include:
- Replacing outdated server.Config references with types.Config and updating related flag variables (e.g. types.MgmtConfigPath).
- Converting engine constants (SqliteStoreEngine, PostgresStoreEngine, MysqlStoreEngine) to use types.Engine for consistent type–safety.
- Adjusting various test and migration code paths to correctly reference the new configuration and engine types.
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

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.

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.
* 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

* Add geoname indexes
* move db file check to connectDB
* Add concurrency safety to SQL queries and database reloading
The commit adds mutex locks to the GetAllCountries and GetCitiesByCountry functions to ensure thread-safety during database queries. Additionally, it introduces a mechanism to safely close the old database connection before a new connection is established upon reloading, which improves the reliability of database operations. Lastly, it moves the checking of database file existence to the connectDB function.
* Add sha256 sum check to geolocation store before reload
* Use read lock
* Check SHA256 twice when reload geonames db

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.
* 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
* Add gocritic linter
`gocritic` provides diagnostics that check for bugs, performance, and style issues
We disable the following checks:
- commentFormatting
- captLocal
- deprecatedComment
This PR contains many `//nolint:gocritic` to disable `appendAssign`.
