eBPF with Rust (Aya)

Purpose

Guide agents through building production eBPF programs in Rust using the Aya framework: writing kernel-side BPF code with aya-bpf, structured logging with aya-log, sharing maps between BPF and userspace, and integrating with async tokio.

Triggers

• "How do I write an eBPF program in Rust?"
• "How do I use the Aya framework?"
• "How do I share a BPF map between kernel and userspace in Rust?"
• "How do I log from a BPF program in Rust?"
• "My Aya program fails to load — how do I debug it?"
• "How do I integrate an eBPF program with tokio?"

Workflow
