server
- Update clknetsim to snapshot f89702d.
- Ensure the correct pool packages are installed for openSUSE and SLE (bsc#1180689).
- Enable syscallfilter unconditionally (bsc#1181826).
Chrony was updated 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 NTP loop test to prevent synchronisation to itself
- Repeat iburst when NTP source is switched from offline state
to online
- Update clock synchronisation status and leap status more
frequently
- Update seccomp filter
- Add 'add pool' command
- Add 'reset sources' command to drop all measurements
- Add authdata command to print details about NTP
authentication

multihomed hosts
- Removed features
- Drop support for RIPEMD keys (RMD128, RMD160, RMD256, RMD320)
- Drop support for long (non-standard) MACs in NTPv4 packets
(chrony 2.x clients using non-MD5/SHA1 keys need to use
option 'version 3')
- By default we don't write log files but log to journald, so
only recommend logrotate.
- Adjust and rename the sysconfig file, so that it matches the
expectations of chronyd.service (bsc#1173277).
Chrony was updated to 3.5.1:
* Create new file when writing pidfile (CVE-2020-14367, bsc#1174911)
- Add chrony-pool-suse and chrony-pool-openSUSE subpackages that
preconfigure chrony to use NTP servers from the respective
pools for SUSE and openSUSE (bsc#1156884, SLE-11424).
- Add chrony-pool-empty to still allow installing chrony without
preconfigured servers.
- Use iburst in the default pool statements to speed up initial
synchronisation (bsc#1172113).
- Update clknetsim to version 79ffe44 (fixes bsc#1162964).
Update to 3.5:
+ Add support for more accurate reading of PHC on Linux 5.0
+ Add support for hardware timestamping on interfaces with read-only timestamping configuration
+ Add support for memory locking and real-time priority on FreeBSD, NetBSD, Solaris
+ Update seccomp filter to work on more architectures
+ Validate refclock driver options
+ Fix bindaddress directive on FreeBSD
+ Fix transposition of hardware RX timestamp on Linux 4.13 and later
+ Fix building on non-glibc systems

- Read runtime servers from /var/run/netconfig/chrony.servers (bsc#1099272)
- Move chrony-helper to /usr/lib/chrony/helper, because there should be no executables in /usr/share.
- Remove discrepancies between spec file and chrony-tmpfiles (bsc#1115529)
Update to version 3.4
* Enhancements
+ Add filter option to server/pool/peer directive
+ Add minsamples and maxsamples options to hwtimestamp directive
+ Add support for faster frequency adjustments in Linux 4.19

without root privileges to remove it on exit
+ Disable sub-second polling intervals for distant NTP sources
+ Extend range of supported sub-second polling intervals
+ Get/set IPv4 destination/source address of NTP packets on FreeBSD
+ Make burst options and command useful with short polling intervals

+ Respond from interface that received NTP request if possible
+ Add onoffline command to switch between online and offline state
according to current system network configuration
+ Improve example NetworkManager dispatcher script
* Bug fixes
+ Avoid waiting in Linux getrandom system call
