Add newfstatat() syscall to seccomp filter allow list. #95

Closed szanni closed 3 years ago

szanni commented 3 years ago

Seemingly newer versions of glibc call newfstatat(), wrapping fstatat() and breaking kutil_openlog().

According to man 2 newfstatat[0] the employed system call might be called fstatat64() on some systems, meaning this patch might not fix all Linux systems.

This fixes #92 on my system.
