Thomas Eizinger 3e9ef4772b feat(gateway): extend flow logs with more client properties (#10717)
In order to make the flow logs emitted by the Gateway more useful and
self-contained, we extend the `authorize_flow` message sent to the
Gateway with some more context around the Client and Actor of that flow.
In particular, we now also send the following to the Gateway:

- `client_version`
- `device_os_version`
- `device_os_name`
- `device_serial`
- `device_uuid`
- `device_identifier_for_vendor`
- `device_firebase_installation_id`
- `identity_id`
- `identity_name`
- `actor_id`
- `actor_email`

We only extend the `authorize_flow` message with these additional
properties. The legacy messages for 1.3.x Clients remain as is. For
those Clients, the above properties will be empty in the flow logs.

Resolves: #10690

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. Provide the token to the Gateway using one of these methods:
    • Set the FIREZONE_TOKEN=<gateway_token> environment variable
    • Set a systemd credential named FIREZONE_TOKEN.
  3. Set FIREZONE_ID to a unique string to identify this gateway in the portal, e.g. export FIREZONE_ID=$(head -c 32 /dev/urandom | sha256sum | cut -d' ' -f1). The Gateway requires this variable at startup. We recommend this to be a 64 character hex string.
  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.
