tos-tbpf

TBPF virtual machine

Description

This tbpf is forked from the Anza-xyz project.

This crate contains a virtual machine for eBPF program execution. BPF, as in Berkeley Packet Filter, is an assembly-like language initially developed for BSD systems, in order to filter packets in the kernel with tools such as tcpdump so as to avoid useless copies to user-space. It was ported to Linux, where it evolved into eBPF (extended BPF), a faster version with more features. While BPF programs are originally intended to run in the kernel, the virtual machine of this crate enables running it in user-space applications; it contains an interpreter, an x86_64 JIT-compiler for eBPF programs, as well as an assembler, disassembler and verifier.

The crate is supposed to compile and run on Linux, MacOS X, and Windows, although the JIT-compiler does not work with Windows at this time.
