tests are not working on my system about fssb

Update:
I added a default: to the switch statement in handle_syscalls that prints unhandled syscalls.
I got this output:

The tests work when i copy the code from SYS_creat to a new case SYS_openat except the path arg is now 1 and the flag arg is now 2. I don't know if this creates new problems or works in all cases though...
