Virtual machine and JIT compiler for eBPF programs.

Modules

Aligned memory

This module translates eBPF assembly language to binary.

Call frame handler

Functions in this module are used to handle eBPF programs with a higher level representation, for example to disassemble the code into a human-readable format.

This module contains all the definitions related to eBPF, and some functions permitting to manipulate eBPF instructions.

This module relocates a BPF ELF

This module contains all the definitions related to eBPF, and some functions permitting to manipulate eBPF instructions.

This module defines memory regions

Module provides API to create eBPF programs by Rust programming language

Interpreter for eBPF programs.

This module defines memory regions

Static Byte Code Analysis

This module implements some built-in syscalls that can be called from within an eBPF program.

This module defines an example user error definition

This “verifier” performs simple checks when the eBPF program is loaded into the VM (before it is interpreted or JIT-compiled). It has nothing to do with the much more elaborated verifier inside Linux kernel. There is no verification regarding the program flow control (should be a Direct Acyclic Graph) or the consistency for registers usage (the verifier of the kernel assigns types to the registers and is much stricter).
