In `connlib`, when a CIDR resource gets disabled, we remove it from the `IpNetworkTable` that does the routing for the packets. This ensures that when we check for the `longest_match` of a packet, disabled resources are not considered. In https://github.com/firezone/firezone/actions/runs/10449400486/job/28931681264?pr=6339, CI found a bug where the reference implementation in the tests diverged from this behaviour because it implements this behaviour slightly differently. To ensure we don't match against a disabled resource, we match all resources, filter out the disabled ones and then pick the one with the highest netmask which should be the most specific one.
Rust development guide
Firezone uses Rust for all data plane components. This directory contains the Linux and Windows clients, and low-level networking implementations related to STUN/TURN.
We target the last stable release of Rust using rust-toolchain.toml.
If you are using rustup, that is automatically handled for you.
Otherwise, ensure you have the latest stable version of Rust installed.
Reading Client logs
The Client logs are written as JSONL for machine-readability.
To make them more human-friendly, pipe them through jq like this:
cd path/to/logs # e.g. `$HOME/.cache/dev.firezone.client/data/logs` on Linux
cat *.log | jq -r '"\(.time) \(.severity) \(.message)"'
Resulting in, e.g.

2024-04-01T18:25:47.238193266Z INFO GIT_VERSION = 1.0.0-pre.11-35-gcc0d43531
