The extended BPF (eBPF) virtual machine allows programs to be loaded into and executed with the kernel — and, increasingly, other environments. As the use of BPF grows, so does interest in defining what the BPF virtual machine actually is. In an effort to ensure a consistent and fair environment for defining what constitutes the official BPF language and run-time environment, and to encourage NVMe vendors to support BPF offloading, a recent effort has been undertaken to standardize BPF.

This early-stage project is not a fork, Redmond insists Share Copy Microsoft on Monday launched an open source project to make a Linux kernel tool known as eBPF, short for Extended Berkeley Packet Filter, work on Windows. Inspired by network packet filtering and capture software dubbed Berkeley Packet Filter, eBPF is a register-based virtual machine designed to run custom 64-bit RISC-like architecture via just-in-time compilation inside the Linux kernel. As such, eBPF programs are particularly well-situated for debugging and system analysis, such as tracing file system and registry ca...
