bpf linuxIn the past few months I’ve been working with Red Sift on RedBPF, a BPF toolkit for Rust. Red Sift uses RedBPF to power the security monitoring agent InGRAINd. Peter recently blogged about RedBPF and InGRAINd, and ran a workshop at RustFest Barcelona. We’ve continued to improve RedBPF since, fixing bugs, improving and adding new APIs, adding support for Google Kubernetes Engine kernels and more. We’ve also completed the relicensing of the project to Apache2/MIT – the licensing scheme used by many of the most prominent crates in the Rust ecosystem – which will hopefully make it even easier to adopt RedBPF.
In this post I’m going to go into some details into what RedBPF is, what its main components are, and what the full process of writing a BPF program looks like.

bpf linuxDuring the product development process monitoring our pipelines proved challenging, and we wanted more visibility into our containers. After a short period of exploration, we found that eBPF would address most of the pain points and dark spots we were encountering.
There was one catch: no eBPF tooling would help us deploy and maintain new probes within our small, but focused ops team. BCC, while great for tinkering, requires significant effort to roll out to production. It also makes it difficult to integrate our toolkit into our usual CI/CD deployment models.
Faced with this dilemma, we decided the only option was for us to write our own Rust-based agent that integrated well with our testing and deployment strategies.
