Crate solana_rbpf

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

interpreter

Interpreter for eBPF programs.

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 for eBPF programs.

Macros

question_mark

Error handling for SyscallObject::call methods
