Tests that need root or mutate host state (nftables/iptables/DNS, TUN/WireGuard
interfaces, routes, eBPF, SSH/service install) are now gated behind a
//go:build privileged tag. The default `go test ./client/...` runs as a non-root
user with no sudo and leaves host networking untouched; mixed files were split so
pure-logic tests stay in the default suite.
A self-hosting ory/dockertest/v4 harness (client/testutil/privileged) runs the
privileged suite inside a --privileged --cap-add=NET_ADMIN container via
`make test-privileged`; a DOCKER_CI=true guard skips the spawn when already inside
the container. Added `make test-unit` for the host-safe run.
- Move `util/grpc` and `util/net` to `client` so `internal` packages can be accessed
- Add methods to return the next best interface after the NetBird interface.
- Use `IP_UNICAST_IF` sock opt to force the outgoing interface for the NetBird `net.Dialer` and `net.ListenerConfig` to avoid routing loops. The interface is picked by the new route lookup method.
- Some refactoring to avoid import cycles
- Old behavior is available through `NB_USE_LEGACY_ROUTING=true` env var
updates the route manager on Unix to use a unique, incrementing sequence number for each route message instead of a fixed value.
Replace the static Seq: 1 with a call to r.getSeq()
Add an atomic seq field and the getSeq method in SysOps
Code cleaning around the util/net package. The goal was to write a more understandable source code but modify nothing on the logic.
Protect the WireGuard UDP listeners with marks.
The implementation can support the VPN permission revocation events in thread safe way. It will be important if we start to support the running time route and DNS update features.
- uniformize the file name convention: [struct_name] _ [functions] _ [os].go
- code cleaning in net_linux.go
- move env variables to env.go file
In the case of user space WireGuard mode, use in-memory proxy between the TURN/Relay connection and the WireGuard Bind. We keep the UDP proxy and eBPF proxy for kernel mode.
The key change is the new wgproxy/bind and the iface/bind/ice_bind changes. Everything else is just to fulfill the dependencies.
This new one uses functions from netioapi.h to monitor route changes.
This change ensures that we include routes that point to virtual
interfaces, such as vEthernet created by the Hyper-V Virtual Switch.
