About:
Libbpf is a userspace library for loading and interacting with BPF (Berkeley Packet Filter) programs and maps. It serves as the modern foundation for high-performance networking and observability tools like BCC and libbpf-tools. Its main value is providing a streamlined, efficient interface to the kernel's BPF virtual machine, enabling powerful system instrumentation.

Key Features:

eBPF object file loading and verification
Interaction with BPF maps and programs
Skeleton generation for type-safe BPF access
Low-level BPF helper function wrappers

Use Cases:

Building high-performance networking and traffic control applications
Creating advanced system observability and monitoring tools
Developing low-overhead security monitoring and policy enforcement

Alternatives:

BCC – BCC includes a full Clang toolchain and is easier for quick scripting, while libbpf is lighter and requires a separate compilation step.
