+* [Bug 1022] Fix compilation problems with yesterday's commit.
+* Updates and cleanup from Dave Mills:
+ I've now spent eleven months of a sabbatical year - 7 days a week, 6-10
+ hours most days - working on NTP. I have carefully reviewed every major
+ algorithm, examined its original design and evolution from that design.
+ I've trimmed off dead code and briar patches and did zillions of tests
+ contrived to expose evil vulnerabilities. The development article is in
+ rather good shape and should be ready for prime time.
+
+ 1. The protostats statistics files have been very useful in exposing
+ little twitches and turns when something hiccups, like a broken PPS
+ signal. Most of what used to be syslog messages are now repackaged as
+ protostats messages with optional syslog as well. These can also be sent
+ as traps which might be handy to tiggle a beeper or celltext. These, the
+ sysstats files and cryptostats files reveal the ambient health of a busy
+ server, monitor traffic and error counts and spot crypto attacks.
+
+ 2. Close inspection of the clock discipline behavior at long poll
+ intervals (36 h) showed it not doing as well as it should. I redesigned
+ the FLL loop to improve nominal accuracy from several tens of
+ milliseconds to something less than ten milliseconds.
+
+ 3. Autokey (again). The enhanced error checking was becoming a major
+ pain. I found a way to toss out gobs of ugly fat code and replace the
+ function with a much simpler and more comprehensive scheme. It resists
+ bait-and-switch attacks and quickly detect cases when the protocol is
+ not correctly synchronized.
+
+ 4. The interface code for the kernel PPS signal was not in sync with the
+ kernel code itself. Some error checks were duplicated and some
+ ineffective. I found none of the PPS-capable drivers, including the atom
+ driver, do anything when the prefer peer fails; the kernel PPS signal
+ remains in control. The atom driver now disables the kernel PPS when the
+ prefer peer comes bum. This is important when the prefer peer is not a
+ reference clock but a remote NTP server.
+
+ 5. The flake restrict bit turned out to be really interesting,
+ especially with symmtric modes and of those especially those using
+ Autokey. Small changes in the recovery procedures when packets are lost
+ now avoid almost all scenarios which previously required protocol resets.
+
+ 6. I've always been a little uncomfortable when using the clock filter
+ with long poll intervals because the samples become less and less
+ correlated as the sample age exceeds the Allan intercept. Various
+ schemes have been used over the years to cope with this fact. The latest
+ one and the one that works the best is to use a modified sort metric
+ where the delay is used when the age of the sample is less than the
+ intercept and the sum of delay and dispersion above that. The net result
+ is that, at small poll intervals the algorithm operates as a minimum
+ filter, while at larger poll intervals it morphs to FIFO. Left
+ unmodified, a sample could be used when twelve days old. This along with
+ the FLL modifications has made a dramatic improvement at large poll
+ intervals.
+
+- [Backward Incompatible] The 'state' variable is no longer reported or
+ available via ntpq output. The following system status bit names
+ have been changed:
+ - sync_alarm -> leap_alarm
+ - sync_atomic -> sync_pps
+ - sync_lf_clock -> sync_lf_radio
+ - sync_hf_clock -> sync_hf_radio
+ - sync_uhf_clock -> sync_uhf_radio
+ - sync_local_proto -> sync_local
+ - sync_udp/time -> sync_other
+ Other names have been changed as well. See the change history for
+ libntp/statestr.c for more details.
+ Other backward-incompatible changes in ntpq include:
+ - assID -> associd
+ - rootdispersion -> rootdisp
+ - pkt_head -> pkt_neader
+ See the change history for other details.
