Front-window bakery material. Catches the eye, delivers the goods.
Summary
This article serves as an introductory guide to eBPF (extended Berkeley Packet Filter), a Linux kernel technology that allows running sandboxed programs in the kernel without modifying kernel source code. It explains how eBPF enables kernel-level programming for monitoring, observability, and extending kernel capabilities safely. The content appears to be an educational tutorial aimed at developers interested in Linux kernel programming and system-level development.
