I am currently working on a project where I need to test a specific Linux kernel function using KLEE. The function in question is btrfs_map_block located in fs/btrfs/volumes.c, and I am focusing on addressing the vulnerability CVE-2019-19816.
Problem: I am unsure about the steps to set up this function to be compatible with KLEE for testing purposes. Additionally, I would like to understand how to incorporate the necessary Linux headers for accurate testing.
Question: What steps should I follow to prepare the btrfs_map_block function for testing with KLEE? How can I ensure the inclusion of relevant Linux headers for proper functioning of the function during KLEE testing?
Important Note: Please provide clear and detailed instructions, and if possible, include examples or references to documentation that can aid in this process. Thank you.
I've experimented with copying other dependent functions. I attempted to directly incorporate the header file into KLEE's setup. I explored alternative approaches to replicating the function's dependencies.
