Using either an interpreter or a JIT compiler, the eBPF will convert the bytecode into actionable machine code. However, eBPF is an event-driven technology, so it runs in response to specific hook points or events within the kernel (system calls, network events, process initiation, CPU idling...
Extended Berkeley Packet Filter (eBPF) is a powerful technology that allows developers to run sandboxed programs in the Linux kernel without changing kernel source code. This guide explores the applications of eBPF in networking, security, and performance monitoring. Learn about the benefits of eBPF ...
The kernel expects all eBPF programs to be loaded as bytecode, so unless bytecode is being written, we need a way to compile higher level languages. To build out this compiler, eBPF usesLLVMas its back-end infrastructure on which a front-end for any programming language can be built. Bec...
Learn what eBPF is and how it offers unparalleled real-time observability, enabling granular insights directly from the kernel.
What is eBPF? eBPF, which is short for extended Berkeley Packet Filter, is a Linux kernel feature that makes it possible to run sandboxed programs within kernel space. eBPF extends the functionality of the operating system in a safe and controlled manner, taking advantage of the kernel's acces...

In order to do so, however, the eBPF programs need to know what data structures they’re dealing with. You can achieve that with one simple line: #include “vmlinux.h”. In this blog, I’ll explain what vmlinux.h is and why you should start using it when writing your eBPF programs...
