Thomas Eizinger 0310bafbcd feat(clients): gracefully close connections on shutdown (#10400)
In #10076, connlib gained the ability to gracefully close connections
between peers. The Gateway already uses this when it is being gracefully
shutdown such as during an upgrade. This allows Clients to immediately
fail-over to a different Gateway instead of waiting for an ICE timeout.

When a Client signs out, we currently just drop all the state, resulting
in an ICE timeout on the Gateway ~15 seconds later. This makes it
difficult for us to analyze, whether an ICE timeout in the logs presents
an actual problem where a network connection got cut or whether the
Client simply signed out.

Whilst not water-tight, attempting to gracefully close our connections
when the Client signs out is better than nothing so we implement this
here.

All Clients use the `Session` abstraction from `client-shared` which
spawns the event-loop into a dedicated task.

- For the Linux and Windows GUI client, the already present tokio
runtime instance of the tunnel service is used for this.
- For Android and Apple, we create a dedicated, single-threaded runtime
instance for connlib.
- For the headless client, we also reuse the already existing tokio
runtime instance of the binary.

In case of Android, Apple and the headless client, this means we need to
ensure the tokio runtime instances stays alive long enough to actually
complete the graceful shutdown task. We achieve this by draining the
`EventStream` returned from `Session`. The `EventStream` is a wrapper
around a channel connected to the event-loop. This stream only finishes
once the event-loop is entirely dropped (and therefore completed the
graceful shutdown) as it holds the sender-end of the channel.

In case of the Linux and Windows GUI client, the runtime outlives the
`Session` because it is scoped to the entire tunnel process. Therefore,
no additional measures are necessary there to ensure the graceful
shutdown task completes.

A modern alternative to legacy VPNs.

Overview

Firezone is an open source platform to securely manage remote access for any-sized organization. Unlike most VPNs, Firezone takes a granular, least-privileged approach to access management with group-based policies that control access to individual applications, entire subnets, and everything in between.

architecture

Features

Firezone is:

  • Fast: Built on WireGuard® to be 3-4 times faster than OpenVPN.
  • Scalable: Deploy two or more gateways for automatic load balancing and failover.
  • Private: Peer-to-peer, end-to-end encrypted tunnels prevent packets from routing through our infrastructure.
  • Secure: Zero attack surface thanks to Firezone's holepunching tech which establishes tunnels on-the-fly at the time of access.
  • Open: Our entire product is open-source, allowing anyone to audit the codebase.
  • Flexible: Authenticate users via email, Google Workspace, Okta, Entra ID, or OIDC and sync users and groups automatically.
  • Simple: Deploy gateways and configure access in minutes with a snappy admin UI.

Firezone is not:

  • A tool for creating bi-directional mesh networks
  • A full-featured router or firewall
  • An IPSec or OpenVPN server

Frequently asked questions (FAQ)

Can I self-host Firezone?

Our license won't stop you from self-hosting the entire Firezone product top to bottom, but our internal APIs are changing rapidly so we can't meaningfully support self-hosting Firezone in production at this time.

If you're feeling especially adventurous and want to self-host Firezone for educational or hobby purposes, follow the instructions to spin up a local development environment in CONTRIBUTING.md.

The latest published clients (on App Stores and on releases) are only guaranteed to work with the managed version of Firezone and may not work with a self-hosted portal built from this repository. This is because Apple and Google can sometimes delay updates to their app stores, and so the latest published version may not be compatible with the tip of main from this repository.

Therefore, if you're experimenting with self-hosting Firezone, you will probably want to use clients you build and distribute yourself as well.

See the READMEs in the following directories for more information on building each client:

How long will 0.7 be supported until?

Firezone 0.7 is currently end-of-life and has stopped receiving updates as of January 31st, 2024. It will continue to be available indefinitely from the legacy branch of this repo under the Apache 2.0 license.

How much does it cost?

We offer flexible per-seat monthly and annual plans for the cloud-managed version of Firezone, with optional invoicing for larger organizations. See our pricing page for more details.

Those experimenting with self-hosting can use Firezone for free without feature or seat limitations, but we can't provide support for self-hosted installations at this time.
