New in version 1.19
|
|

|
|
|
|
* Auto-detect kernel's timer interrupt rate (so-called 'HZ') when chronyd

|
|
assertions.
|
|
* Fix bugs in clamping code for the tick value used when slewing a large
|
|
offset.
|
|

|
|
building awkward as ordinary user.)
|
|
* Include chrony.spec file for building RPMs
|
|
|
|
New in version 1.18
|
|
===================
|
|
* Amend homepage and mailing list information to chrony.sunsite.dk
|
|
* Delete pidfile on exit from chronyd.
|
|
* Improvements to readline interface to chronyc
|

|
|
* More things in contrib directory.
|
|
* New options to help package builders: --infodir/--mandir for configure, and

DESTDIR=xxx for make. (See section 2.2 of chrony.txt for details).
|
|
* Changed the wording of the messages generated by mailonchange and logchange
|
|
directives.
|
|
|
|
New in version 1.17
|
|
===================
|
|
* Port to NetBSD
|
|
* Configuration supports Linux on PPC
|
|
* Fix compilation warnings
|
|
* Several documentation improvements
|
|
* Bundled manpages (taken from the 'missing manpages project')
|
|
* Cope with lack of bzero function for Solaris 2.3 systems
|
|
* Store chronyd's pid in a file (default /var/run/chronyd.pid) and check if
|
|
chronyd may already be running when starting up. New pidfile directive in
|
|
configuration file.
|
|
* Any size subnet is now allowed in allow and deny commands. (Example:
|
|
6.7.8/20 or 6.7.8.x/20 (any x) mean a 20 bit subnet).
|
|
* The environment variables CC and CFLAGS passed to configure can now be used
|
|
to select the compiler and optimisation/debug options to use
|
|
* Write syslog messages when chronyd loses synchronisation.
|
|
* Print GPL text when chronyc is run.
|
|
* Add NTP broadcast server capability (new broadcast directive).
|
|
* Add 'auto_offline' option to server/peer (conf file) or add server/peer (via
|
|
chronyc).
|
|
* Add 'activity' command to chronyc, to report how many servers/peers are
|
|
currently online/offline.
|
|
* Fix long-standing bug with how the system time quantum was calculated.
|
|
* Include support for systems with HZ!=100 (HZ is the timer interrupt
|
|
frequency).
|
|
* Include example chrony.conf and chrony.keys files (examples subdirectory).
|
|
* Include support for readline in chronyc.
|
|
|
|
New in version 1.16.1
|
|
=====================
|
|
* Fix compilation problem on Linux 2.4.13 (spinlock.h / spinlock_t)
|
|
|
|
New in version 1.16
|
|
===================
|
|
* More informative captions for 'sources' and 'sourcestats' commands in chronyc
|
|
(use 'sources -v' and 'sourcestats -v' to get them).
|
|
* Correct behaviour for Solaris versions>=2.6 (dosynctodr not required on these
|
|
versions.)
|
|
* Remove some compiler warnings (Solaris)
|
|
* If last line of keys file doesn't have end-of-line, don't truncate final
|
|
character of that key.

|
|
* Minor documentation updates and improvements.

|
|
|
New in version 1.15
|
|
===================
|
|
* Add contributed change to 'configure' to support Solaris 2.8 on x86
|
|
* Workaround for assertion failure that arises if two received packets occur
|
|
close together. (Still need to find out why this happens at all.)
|
|
* Hopefully fix problem where fast slewing was incompatible with machines
|
|
that have a large background drift rate (=> tick value went out of range
|
|
for adjtimex() on Linux.)
|
|
* Fix rtc_linux.c compile problems with 2.4.x kernel include files.
|
|
* Include support for RTC device not being at /dev/rtc (new rtcdevice directive
|
|
in configuration file).
|
|
* Include support for restricting network interfaces for commands (new
|
|
bindcmdaddress directive in configuration file)
|
|
* Fix potential linking fault in pktlength.c (use of CROAK macro replaced by
|
|
normal assert).
|
|
* Add some material on bug reporting + contributing to the chrony.texi file
|
|
* Made the chrony.texi file "Vim6-friendly" (removed xrefs on @node lines,

|
|
New in version 1.1
|
|
==================
|
|
|
|
Bug fixes
|
|
---------
|
|
|
|
* Made linear regression more resistant to rounding errors (old one
|
|
occasionally generated negative variances which made everything go
|
|
haywire). Trap infinite or 'not-a-number' values being used to
|
|
alter system clock to increase robustness further.
|
|
|
|
Other changes/Enhancements
|
|
--------------------------
|
|
|
|
* Support for Linux 2.1 and 2.2 kernels
|
|
|
|
* New command 'makestep' in chronyc to immediately jump the system
|
|
time to match the NTP estimated time (Linux only) - a response to
|
|
systems booting an hour wrong after summertime/wintertime changes,
|
|
due to RTCs running on local time. Needs extending to Sun driver
|
|
files too.
|
|
|
|
* New directives 'logchange' and 'mailonchange' to log to syslog or
|
|
email to a specific address respectively if chronyd detects a clock
|
|
offset exceeding a defined threshold.
|
|
|
|
* Added capability to log all client/peer NTP accesses and command
|
|
accesses (can be turned off with conf file directive 'noclientlog').
|
|
Added 'clients' command to chronyc to display this data.
|
|
|
|
* Improved manual mode to use robust regression rather than 2 point
|
|
fit.
|
|
|
|
* Added 'manual list' and 'manual delete' commands to chronyc to
|
|
allow display of entered timestamps and discretionary deletion of
|
|
outliers.
|
|
|
|
* If host goes unsynchronised the dummy IP address 0.0.0.0 is detected
|
|
to avoid attempting a reverse name lookup (to stop dial on demand IP
|
|
links from being started)
|
|
|
|
* Changed chronyc/chronyd protocol so messages are now all variable
|
|
length. Saves on network bandwidth particularly for large replies
|
|
from chronyd to chronyc (to support the clients command).
|
|
|
|
* Added bindaddress directive to configuration file, to give
|
|
additional control over limiting which hosts can access the local
|
|
server.
|
|
|
|
* Groundwork done for a port to Windows NT to compile with Cygwin
|
|
toolkit. chronyc works (to monitor another host). sys_winnt.c
|
|
needs finishing to use NT clock control API. Program structure
|
|
needs adapting to use Windows NT service functions, so it can be
|
|
started at boot time. Hopefully a Windows NT / Cygwin guru with
|
|
some spare time can take this port over :-)
|
|
|
|
New in version 1.02
|
|
===================
|
|
|
|
Bug fixes
|
|
---------
|
|
|
|
* Fix error messages in chronyc if daemon is not reachable.
|
|
|
|
* Fix config file problem for 'allow all' and 'deny all' without a
|
|
trailing machine address.
|
|
|
|
* Remove fatal failed assertion if command socket cannot be read from
|
|
in daemon.
|
|
|
|
* Rewrote timezone handling for Linux real time clock, following
|
|
various reported problems related to daylight saving.
|
|
|
|
Other changes/Enhancements
|
|
--------------------------
|
|
|
|
* Configure script recognizes BSD/386 and uses SunOS 4.1 driver for
|
|
it.
|
|
|
|
* Log files now print date as day-month-year rather than as a day
|
|
number. Milliseconds removed from timestamps of logged data.
|
|
Banners included in file to give meanings of columns.
|
|
|
|
* Only do 1 initial step (followed by a trimming slew) when
|
|
initialising from RTC on Linux (previously did 2 steps).
|
|
|
|
New in version 1.01
|
|
===================
|
|
|
|
Bug fixes
|
|
---------
|
|
|
|
* Handle timezone of RTC correctly with respect to daylight saving
|
|
time
|
|
|
|
* Syntax check the chronyc 'local' command properly
|
|
|
|
* Fixed assertion failed fault in median finder (used by RTC
|
|
regression fitting)
|
|
|
|
Other changes/Enhancements
|
|
--------------------------
|
|
|
|
* Log selection of new NTP reference source to syslog.
|
|
|
|
* Don't zero-pad IP address fields
|
|
|
|
* Add new command to chronyc to allow logfiles to be cycled.
|
|
|
|
* Extend allow/deny directive syntax in configuration file to so
|
|
directive can apply to all hosts on the Internet.
|
|
|
|
* Tidy up printout of timestamps to make it clear they are in UTC
|
|
|
|
* Make 'configure' check the processor type as well as the operating
|
|
system.
