BorrowSanitizer is a work-in-progress LLVM instrumentation pass for detecting aliasing violations in multi-language Rust applications. Our project is still in early development, but may help you find cross-language bugs otherwise undetectable by Miri. Our goal is to support detecting the following types of errors:

* Violations of Rust's [*Tree Borrows*](https://perso.crans.org/vanille/treebor/) aliasing model.
* Accesses out-of-bounds
* Use-after free errors.

This project contains a fork of Miri's borrow tracker ([`bsan-shared`](https://github.com/BorrowSanitizer/bsan/tree/main/bsan-shared), [`bsan-rt`](https://github.com/BorrowSanitizer/bsan/tree/main/bsan-rt)), as well as several other components from both Miri and the Rust compiler.

Check out [our website](https://borrowsanitizer.com) for more information.

## Usage
The easiest way to try BorrowSanitizer is inside a Docker container. Our image supports the following platforms:

|   **Platform**    |         **Target**            | **Description**            |
|-------------------|-------------------------------|----------------------------|
|   `linux/amd64`   | `aarch64-unknown-linux-gnu`   |ARM64 Linux                 |
|   `linux/arm64`   |  `x86_64-unknown-linux-gnu`   |X86 Linux                   |

First, pull our [latest image](https://github.com/BorrowSanitizer/bsan/pkgs/container/bsan) from GitHub's container registry.
```
docker pull ghcr.io/borrowsanitizer/bsan:latest
```
Then, launch a container and attach a shell.
```
docker run -it bsan:latest
```
Once inside the container, you can use our Cargo plugin to build and test crates using BorrowSanitizer. 
```
cargo bsan test
```
Our plugin supports most of the same subcommands as Miri. When it's used for the first time, it will perform a one-time setup step of building an instrumented sysroot. You can trigger this step manually using the `setup` subcommand.

## Building from Source
Every single command needed to build, test, and install BorrrowSanitizer can be accessed through `xb`, our build script. For first-time setup, run:
```
xb setup
```
This will install a [custom Rust toolchain](https://github.com/BorrowSanitizer/rust) under the name `bsan`.
Then, to install BorrowSanitizer, run:
```
xb install
```
This will place our tool's binaries into Cargo's [home directory](https://doc.rust-lang.org/cargo/guide/cargo-home.html) (`$HOME/.cargo`). You will need to have `bsan` set as the active toolchain (e.g. `rustup default bsan`) for our tool to work.

You can build and test components of the project using the `build` and `test` subcommands. For example, running `xb build` will build everything, but you can also pass the name of a subdirectory to build just that component, like so:
```
xb build bsan-rt
```
Nearly every subcommand can be used this way.

After making a change, you should run all of our CI steps locally using:
```
xb ci
```
