struct audit_rule_data {
[...]
char buf[0]; /* string fields buffer */
};
The last element in the struct is 0 length. But the allocation in
audit_krule_to_data() looks like:
data = kmalloc(sizeof(*data) + krule->buflen, GFP_KERNEL);
So now data->buf appears as an allocation of size krule->buflen.
We do not need to free it separately. This is a pretty common C trick.
