How about a closer collaboration?

I stumbled upon hase today when I was googling for an VEX IROp. This is a really cool project, and I like it (it actually killed one of my project ideas).

I wonder what the status of hase is, and what plan you have in mind for hase to move forward in the near future. We have some research projects that can really benefit from hase.

It seems that some angr updates broke hase in the past. One way to solve this problem gracefully is to add hase to angr CI, so we can make sure that new commits and PRs to master will not break hase (or at least, you will get a notification from us if we really have to break compatibility).

Also, it would be great if we can incorporate your "angr hacks" in your angr fork to angr master. Most of the code there looks legitimate to me.

Looking forward to your reply!

I am sorry to say that I gave up on this project. There were too many problems I didn't know how to solve given the time constraint of my PhD. And also my motivation dropped in the process.

Feel free to use any code or data of this project or ask questions regarding the implementation. In particular the recording part should be quiet good, having only up to 1% overhead in the SPEC benchmark: https://github.com/hase-project/hase/blob/master/hase/pt.py

We also collected crash traces of a large corpus for a rather large corpus, that might be helpful: https://github.com/hase-project/bug-db
You can download the collected traces/coredumps using via the rsync protocol:

rsync -va thalheim.io::hase /tmp/hase

Thanks for replying! I think this is a great project, and I’m sorry to hear that you do not plan to continue it.

What license does hase use? There isn’t any license as far as I know.

[Mic92]

Good point. I actually added a license file to my project, but forgot to push it:

https://github.com/hase-project/hase/blob/master/LICENSE.md

Same license as angr to keep things simple.

Hey Fish, I hope you are doing well. I hope we can collaborate on this. We are trying to see what kind of resources we can dedicate to this on our end, and we'll be in touch very soon.

I hope we can collaborate on this.

Yep! That'll be great. It would be awesome to know your plans for this project to move forward, as well as your research ideas. We should collaborate on both fronts.

@Mic92 Thanks for choosing BSD 2!
