Segmentation fault on pthread_create when initializing connections

[deukyeon]

Note that this issue is not from Assise but the syscall_intercept library. But this will be useful if your system uses GLIBC 3.25 or higher.

When initializing Assise, threads for communication between LibFS and KernFS are created via pthread_create(). In recent systems, the pthread_create() invokes a system call with SYS_clone3, instead of SYS_clone. Unfortunately, the current syscall_intercept does not handle this syscall correctly, so it causes a segmentation fault in the syscall_intercept library.

If you were struggling with this segmentation fault, you would like to fix the syscall_intercept code based on this issue.

Today(09/12/2022), this code still does not handle the issue properly.

Hope this knowledge helps you.
