Expand description

Virtual machine and JIT compiler for eBPF programs.

Modules

  • aligned_memory
    Aligned memory
  • assembler
    This module translates eBPF assembly language to binary.
  • call_frames
    Call frame handler
  • disassembler
    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.
  • ebpf
    This module contains all the definitions related to eBPF, and some functions permitting to manipulate eBPF instructions.
  • elf
    This module relocates a BPF ELF
  • error
    This module contains all the definitions related to eBPF, and some functions permitting to manipulate eBPF instructions.
  • fuzz
    This module defines memory regions
  • insn_builder
    Module provides API to create eBPF programs by Rust programming language
  • memory_region
    This module defines memory regions
  • static_analysis
    Static Byte Code Analysis
  • syscalls
    This module implements some built-in syscalls that can be called from within an eBPF program.
  • user_error
    This module defines an example user error definition
  • verifier
    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).
  • vm
    Virtual machine and JIT compiler for eBPF programs.
