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.
