Porting PRoot to Rust

[oxr463]

Project Title: Porting PRoot to Rust

Description:

There is already a proof of concept in progress, (See: https://github.com/proot-me/proot-rs). However, this implementation is very basic and only runs on a single architecture. Work is still needed to complete a functioning prototype, as outlined here, https://github.com/proot-me/proot-rs/issues/1:

Remaining steps for the bare minimum (single-tracee, no glue, no extensions, no ptrace-translation, no unix-socket translation, no qemu, -r/-R, -w and -b cli options only, no seccomp, and x86-64 with 64bits programs only)

Deliverable:

Fully functional, albeit minimal, PRoot implementation written in Rust.

Mentor: @oxr463

Skills: ptrace, rust

Skill Level: Medium

Get started: See: https://github.com/proot-me/proot-rs/issues/1

Hi oxr463,

I'm imlk, and I am studying computer science at Beijing University of Posts and Telecommunications in China. I have experience in developing toy operating systems using Rust, and I used to work as an intern in a company that uses the Rust language.

I saw this idea on GSOC. I am very interested in the work of Porting PRoot to Rust and intend to participate in it.

I forked the code and have made some changes (https://github.com/KB5201314/proot-rs) :

• CI: I noticed that the introduction of Travis CI happened before the GitHub Action was released, so I replaced it with the Github Action, which is more convenient.

• Fix build problems, such as build failure caused by lazy_static, llvm_asm, and syscall

• Pre-commit hook: Setup git hooks so that we can check the code format before submitting https://github.com/KB5201314/proot-rs/commit/da19bd12ea667f530dced82e24cca782571ee81e

• Fixed some problems detected by cargo clippy https://github.com/KB5201314/proot-rs/commit/7d537c0ed0874f11d6e7d67f0668c7ab0907414c

Currently, I'm still gaining an understanding of the existing code. I think it will be beneficial to start with fixing the cargo test failure. :)
