umnsec / crix Goto Github PK

hello,
for disabling inlining, there is a patch file in your repository.
how can I apply it to my downloaded llvm-10?
Thank you

Paper https://www-users.cs.umn.edu/~kjlu/papers/crix.pdf describes Two-Layer Type Analysis that refines type analysis by restricting the indirect call targets based on struct types. It appears in the code this is referred as MLTA, and implemented in function findCalleesWithMLTA in file CallGraph.cc. However, I notice the code seems to be missing the second layer refinement based on the struct types. You apparently collect struct type definitions to CallGraphPass::typeConfineMap, but it is not used anywhere to actually refine the call targets.

Is the published version perhaps not the final version of the code?

Thanks for providing this project for others to experiment with. To make it clear for people considering to built upon the work you have done, I suggest you add a license and state the copyright holder. This way you set the terms under which others can reuse your software.

Github projects without a license are not open source as explained in: https://docs.github.com/en/github/creating-cloning-and-archiving-repositories/licensing-a-repository#choosing-the-right-license.

Can you please add an open source license to the project?

Hi, your work on detecting missing checks is very interesting! The Usenix slides pointed me to this repo, but I only see the rewritten error code headers. Is the rest of the code available?
