BPF From Scratch In Rust

Learn how to write a BPF program in Rust from scratch without using macros, frameworks, or hidden helpers. The post explains how to set up the Rust build toolchain, write a minimal BPF program that hooks into a tracepoint, and use the 'yeet' CLI and its daemon 'yeetd' to load and manage the BPF program. A step-by-step guide is provided to create, build, and run the BPF program, ensuring it integrates seamlessly with the Linux kernel and prints live output to the trace pipe.
