This is odd. libcap-1.x should be passing in 0x19980330.
Next, given the -EINVAL return value ntpd should be seeing a NULL result from cap_get_proc() and exiting right there.
What version of ntpd is this? (I must be looking at a wrong value, but even so the fact that cap_get_proc()->capget() is using 0x20071026 for version doesn't make sense)
