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
* 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.

* 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`.
- dupword checks for duplicate words in the source code
- durationcheck checks for two durations multiplied together
- forbidigo forbids identifiers
- mirror reports wrong mirror patterns of bytes/strings usage
- misspell finds commonly misspelled English words in comments
- predeclared finds code that shadows one of Go's predeclared identifiers
- thelper detects Go test helpers without t.Helper() call and checks the consistency of test helpers
Some reverse proxies might find 15s interval too short and respond with an enhance your-calm message
This change is setting the management and signal clients' keepalive interval to 30 seconds to minimize the number of reconnections
Add new feature to notify the user when new client route has arrived.
Refactor the initial route handling. I move every route logic into the route
manager package.
* Add notification management for client rules
* Export the route notification for Android
* Compare the notification based on network range instead of id.
Increased the default send timeout from 2 to 5
Added a max of 4 retries
with an increased timeout after the second attempt
using the grpc client context and
checking the error value for canceled context
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
Fix the status indication in the client service. The status of the
management server and the signal server was incorrect if the network
connection was broken. Basically the status update was not used by
the management and signal library.
Before defining if we will use direct or proxy connection we will exchange a
message with the other peer if the modes match we keep the decision
from the shouldUseProxy function otherwise we skip using direct connection.
Added a feature support message to the signal protocol
Added additional common blacklisted interfaces
Updated the signal protocol to pass the peer port and netbird version

This PR fixes a race condition that happens
when agents connect to a Signal stream, multiple
times within a short amount of time. Common on
slow and unstable internet connections.
Every time an agent establishes a new connection
to Signal, Signal creates a Stream and writes an entry
to the registry of connected peers storing the stream.
Every time an agent disconnects, Signal removes the
stream from the registry.
Due to unstable connections, the agent could detect
a broken connection, and attempt to reconnect to Signal.
Signal will override the stream, but it might detect
the old broken connection later, causing peer deregistration.
It will deregister the peer leaving the client thinking
it is still connected, rejecting any messages.
Right now Signal Service runs the Let'sEncrypt manager on port 80
and a gRPC server on port 10000. There are two separate listeners.
This PR combines these listeners into one with a cmux lib.
The gRPC server runs on either 443 with TLS or 80 without TLS.
Let's Encrypt manager always runs on port 80.
The Management client will try reconnecting in case.
of network issues or non-permanent errors.
If the device was off-boarded, then the client will stop retrying.
