Good day.
ntpd currently performs constraints checking on startup, but once the
constraints are successfully checked cstr->state remains in
STATE_REPLY_RECEIVED forever. As such, the constraints are never checked again.
The following patch has resolved this for me, and constraints checking now
proceeds every CONSTRAINT_SCAN_INTERVAL.
