Chrony was updated to 4.1, bringing features and bugfixes.
Update to 4.1
* Add support for NTS servers specified by IP address (matching Subject
Alternative Name in server certificate)
* Add source-specific configuration of trusted certificates
* Allow multiple files and directories with trusted certificates
* Allow multiple pairs of server keys and certificates
* Add copy option to server/pool directive
* Increase PPS lock limit to 40% of pulse interval
* Perform source selection immediately after loading dump files
* Reload dump files for addresses negotiated by NTS-KE server
* Update seccomp filter and add less restrictive level
* Restart ongoing name resolution on online command
* Fix dump files to not include uncorrected offset
* Fix initstepslew to accept time from own NTP clients
* Reset NTP address and port when no longer negotiated by NTS-KE server
- Ensure the correct pool packages are installed for openSUSE and SLE
(bsc#1180689).
- Fix pool package dependencies, so that SLE prefers chrony-pool-suse
over chrony-pool-empty. (bsc#1194229)
- Enable syscallfilter unconditionally [bsc#1181826].
Update to 4.0
- Enhancements
- Add support for Network Time Security (NTS) authentication
- Add support for AES-CMAC keys (AES128, AES256) with Nettle
- Add authselectmode directive to control selection of unauthenticated
sources
- Add binddevice, bindacqdevice, bindcmddevice directives
- Add confdir directive to better support fragmented configuration
- Add sourcedir directive and 'reload sources' command to support
dynamic NTP sources specified in files
- Add clockprecision directive
- Add dscp directive to set Differentiated Services Code Point (DSCP)
- Add -L option to limit log messages by severity
- Add -p option to print whole configuration with included files
- Add -U option to allow start under non-root user
- Allow maxsamples to be set to 1 for faster update with -q/-Q
option
- Avoid replacing NTP sources with sources that have unreachable
address
- Improve pools to repeat name resolution to get 'maxsources' sources
- Improve source selection with trusted sources
- Improve NTP loop test to prevent synchronisation to itself
- Repeat iburst when NTP source is switched from offline state to
online
