Thomas Eizinger e169150ee7 fix(gateway): don't errenously suspend eventloop (#4486)
Within the gateway's eventloop, we MUST only return `Poll::Pending` if
`Waker`s are registered for anything that needs to happen. To ensure
that, we MUST `loop` around our the calls to `poll()` to ensure we drain
everything that is `Poll::Ready`.

Only once all sub-state machines return `Poll::Pending`, we can return
`Poll::Pending`.

gateway

This crate houses the Firezone gateway.

Building

You can build the gateway using: cargo build --release --bin firezone-gateway

You should then find a binary in target/release/firezone-gateway.

Running

The Firezone Gateway supports Linux only. To run the Gateway binary on your Linux host:

  1. Generate a new Gateway token from the "Gateways" section of the admin portal and save it in your secrets manager.
  2. Ensure the FIREZONE_TOKEN=<gateway_token> environment variable is set securely in your Gateway's shell environment. The Gateway requires this variable at startup.
  3. Set FIREZONE_ID to a unique string to identify this gateway in the portal, e.g. export FIREZONE_ID=$(uuidgen). The Gateway requires this variable at startup.
  4. Now, you can start the Gateway with:
firezone-gateway

If you're running as a non-root user, you'll need the CAP_NET_ADMIN capability to open /dev/net/tun. You can add this to the gateway binary with:

sudo setcap 'cap_net_admin+eip' /path/to/firezone-gateway

Ports

The gateway requires no open ports. Connections automatically traverse NAT with STUN/TURN via the relay.
