How do I run it?
The same way we did it here: https://groups.google.com/d/msg/syzkaller/MHXa-o8foyc/yrGfDOrwAQAJ This will run it in infinite loop in 10 parallel processes: ./syz-execprog -repeat=0 -procs=10 -sandbox=namespace gistfile1.txt -sandbox=namespace will require CONFIG_USER_NS=y, I am not sure if it is actually required, but that's how bots triggered it. You can do -sandbox=none as well.
