For

even though all program instructions are valid, the program has been
rejected because it was deemed unsafe.
This may be because it may have
accessed a disallowed memory region or an uninitialized stack/register or
because the function constraints don't match the actual types or because
there was a misaligned memory access.
In this case, it is recommended to call
.BR bpf ()
