Besspin-GFE notes

Intro info

  • You can follow here to install bluspec: https://gulmezmerve.github.io/posts/2024/03/bluspec-1/ (get just bin file)

  • Add to path e.g., export PATH="$PATH:/bsc-2023.07-debian-12.1/bin/ to ~/.bashrc and source it

  • The active development CHERI-Toooba core: https://github.com/CTSRD-CHERI/Toooba

Get BESSPIN GPE

  • git clone git@github.com:gulmezmerve/BESSPIN-GFE.git

  • Follow the https://github.com/gulmezmerve/BESSPIN-GFE?tab=readme-ov-file#update-dependencies

  • BESSPIN GPE: https://github.com/CTSRD-CHERI/BESSPIN-GFE has Toooba as a submodule https://github.com/CTSRD-CHERI/BESSPIN-GFE/tree/cambridge/bluespec-processors/P3. But it is not updated as a submodule. Please get the updated the version..

  • Small note: Info ‘bluespec_p3’ refers to Toooba core:

Compile the code

src_SSITH_P3/
make clean
make
make compile

Generate the bitstreams

cd $GFE_REPO
./setup_soc_project.sh bluespec_p3 
./build.sh bluespec_p3

Utily Report

At the beginning of my PhD I at first became interested in the broader area of cybersecurity, but my current line of research really got me into the area of systems security. In particular improving the cyber-resilience and availability low-level systems software against memory corruption attacks. This has required me to develop skills, such as in-depth knowledge of the C and Rust runtimes, as well as assembly programming.

The CrowdStrike outage shows that improving software resilience and availability is as important as detecting and mitigating memory-safety vulnerabilities.

LLVM

I have been learning LLVM for a while; I added a function and variable attribute, new compiler options, wrote a hacky LLVM transformation pass, and deleted my hacky stuff in the backend! I kind of enjoyed it, kind of annoyed; in the end, I think it was good to learn!

To install the BSC compiler, follow these steps (example for Ubuntu):

Example for Ubuntu

wget https://github.com/B-Lang-org/bsc/releases/download/2023.07/bsc-2023.07-ubuntu-22.04.tar.gz 
cd ~/cheri/bsc-2023.07-debian-12.1 
export PATH="$PATH:/home/cheri/bsc-2023.07-ubuntu-22.04/bin/

It’s likely that you will also need the Bluespec library. It took me a long time to understand what was missing. You need to install this library from the following repository:
