With the fix of taking into account link-scoped routes in #10554 we introduced a bug: If a customer defines routes in Firezone that conflict with the link-scope ones, those currently take priority as they are usually more specific. To fix this, we introduce tiered routing tables controlled by a set of rules with different priority. 1. In the first "Firezone" routing table, we add all CIDR/IP routes that users define in Firezone. 2. In the second "Firezone" routing table, we sync in all link-scope routes from the system. 3. In the third "Firezone" routing table, we only add the Internet Resource if it is active. By evaluating the routing tables in this order, we effectively always prioritize Firezone-controlled routes over local ones but still allow access to LAN resources when the Internet Resource is active. --------- Signed-off-by: Thomas Eizinger <thomas@eizinger.io> Co-authored-by: Jamil <jamilbk@users.noreply.github.com>
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.
2024-04-01T18:25:47.237661392Z INFO started log
2024-04-01T18:25:47.238193266Z INFO GIT_VERSION = 1.0.0-pre.11-35-gcc0d43531
2024-04-01T18:25:48.295243016Z INFO No token / actor_name on disk, starting in signed-out state
2024-04-01T18:25:48.295360641Z INFO null
Benchmarking on Linux
The recommended way for benchmarking any of the Rust components is Linux' perf utility.
For example, to attach to a running application, do:
- Ensure the binary you are profiling is compiled with the
releaseprofile. sudo perf record -g --freq 10000 --pid $(pgrep <your-binary>).- Run the speed test or whatever load-inducing task you want to measure.
sudo perf script > profile.perf- Open profiler.firefox.com and load
profile.perf
Instead of attaching to a process with --pid, you can also specify the path to executable directly.
That is useful if you want to capture perf data for a test or a micro-benchmark.
