DARPA: Translating All C to Rust (TRACTOR) (users.rust-lang.org)

The TRACTOR program aims to automate the translation of legacy C code to Rust. The goal is to achieve the same quality and style that a skilled Rust developer would produce, thereby eliminating the entire class of memory safety security vulnerabilities present in C programs. This program may involve novel combinations of software analysis, such as static analysis and dynamic analysis, and machine learning techniques like large language models.

Highlights from the forum thread:

There's even a conspiracy theory that the Rust Foundation's 501 organization type was chosen so it can conduct lobbying. The implication being that the Rust Foundation is behind government recommendations to move toward memory safe languages. (Big Borrow-Checker, if you will).

Assuming a worst case scenario, this could be the worst thing to happen to Rust’s image. We end up with billions of lines of rewritten Rust code that is full of soundness and logic bugs, and that no one understands.

DARPA funds some projects on a "there is an infinitesimal chance of success, but if you succeed, it's a big deal" basis. Silent Talk is an example here - very unlikely to succeed, even at the beginning, but if you could hold a radio conversation without sound, that'd be a huge deal for special operations forces.

I don't even understand how they are going to get around the memory security they are doing this translation for. Watch them have to break the security features of Rust just to make certain programs work.

I would expect that's part of the point, if a C program can't be converted to a language that doesn't allow memory violations that probably indicates that there are execution pathways that result in memory violations.
