  Much of ntpd’s most convoluted code lives in ntp_proto.c, which
  implements the state machine central to the protocol. Of the 29
  vulnerabilities that have received CVEs so far in 2016, a couple
  of multi-KLOC functions in ntp_proto.c are responsible for 15 of
  them — just over half. Of course, "just rip it out" wouldn’t
  suffice in this case: this is core business logic, not junk code.
  So we rewrote those functions from scratch, cutting line count
  considerably and yielding a far more readable result.
