This whitepaper introduces eBPF as a major evolution of Linux kernel programmability that extends far beyond packet filtering. It explains how eBPF programs are written in user space, verified for safety, attached to kernel hook points such as syscalls, tracepoints, file-system events, and network events, and then exchange data through maps and perf events. The paper emphasizes why eBPF is a breakthrough: high performance, dynamic updates, rich kernel context, and safer extensibility than traditional kernel modules. It also explores practical adoption across observability and security tools and makes a strong case for eBPF as the data and enforcement layer for AI-driven systems, enabling real-time telemetry, behavioral detection, adaptive policies, and in-kernel automated response.
