This blog post describes vmlinux.h — a generated header containing all kernel type definitions — and shows how to generate it with bpftool so eBPF programs can correctly interpret kernel data structures. It also explains how libbpf’s CO:RE mechanisms (e.g., BPF_CORE_READ) help compiled eBPF programs remain portable across different Linux kernel versions.
