eBPFeBPF (extended Berkeley Packet Filter) is a Linux kernel tec… is a core and increasingly ubiquitous technology for networking, observability, and security.
eBPFeBPF (extended Berkeley Packet Filter) is a Linux kernel tec… has been evolving in Linux kernels for a decade, it has matured as *the* way to secure workloads running on both Linux and also Windows– and it’s the increasing use cases and scope that is revolutionizing security across the cloud and the internet.
When security and development pros use eBPFeBPF (extended Berkeley Packet Filter) is a Linux kernel tec… for security, they are doing so to answer these questions:
In this article we’ll explore how eBPFeBPF (extended Berkeley Packet Filter) is a Linux kernel tec… has grown in popularity among observability and security circles in recent years, and what the future looks like.
eBPFeBPF (extended Berkeley Packet Filter) is a Linux kernel tec… was originally developed as a way to filter network packets in the Linux kernel. eBPFeBPF (extended Berkeley Packet Filter) is a Linux kernel tec… has matured into a powerful tool for tracing and analysing system activity — but it is not just a packet filter anymore.
eBPFeBPF (extended Berkeley Packet Filter) is a Linux kernel tec… is a technology that allows running sandboxed programs in the kernel, extending its capabilities without changing its source code or loading kernel modules.
Brendan Gregg, a computer scientist at Intel said:
eBPFeBPF (extended Berkeley Packet Filter) is a Linux kernel tec… is superpowers for Linux
eBPFeBPF (extended Berkeley Packet Filter) is a Linux kernel tec… evolved from the classic Berkeley Packet Filter (BPF), which was introduced in 1993 as a way of filtering network packets in the kernel.
In the beginning, the original BPF had a limited instruction set and only two 32-bit registers.
But since 2014, Alexei Starovoitov and Daniel Borkmann proposed an extended version of BPF (eBPFeBPF (extended Berkeley Packet Filter) is a Linux kernel tec…), which added ten 64-bit registers, new instructions, a call instruction, and a register passing convention, and a different encoding for the instructions.
They also added an in-kernel verifier that checks the safety and validity of the programs before loading them into the kernel. The verifier ensures that the programs do not crash, hang, or interfere with the kernel negatively. The programs can also be either interpreted or JIT compiled for native execution performance.
in the past decade, eBPFeBPF (extended Berkeley Packet Filter) is a Linux kernel tec… has been enhanced with many additional features:
eBPFeBPF (extended Berkeley Packet Filter) is a Linux kernel tec… has also attracted a large community of contributors and users from various domains and industries.
Linus Torvalds, the Linux OG, said of BPF (exchangeable with eBPFeBPF (extended Berkeley Packet Filter) is a Linux kernel tec…):
BPF has actually been really useful, and the real power of it is how it allows people to do specialized code that isn’t enabled until asked for. Things like tracing and statistics (and obviously network filters) are prime examples of things where people want to do
