Security update for chrony
Description of the patch
This update for chrony fixes the following issues:
- Update to version 4.8:
* Add maxunreach option to limit selection of unreachable sources
* Add -u option to chronyc to drop root privileges (default
chronyc user is set by configure script)
* Fix refclock extpps option to work on Linux >= 6.15
* Validate refclock samples for reachability updates
- Fix racy socket creation which allows privilege escalation to root (bsc#1246544)
- Update to version 4.7:
* Add opencommands directive to select remote monitoring
commands
* Add interval option to driftfile directive
* Add waitsynced and waitunsynced options to local directive
* Add sanity checks for integer values in configuration
* Add support for systemd Type=notify service
* Add RTC refclock driver
* Allow PHC refclock to be specified with network interface name
* Don’t require multiple refclock samples per poll to simplify
filter configuration
* Keep refclock reachable when dropping samples with large delay
* Improve quantile-based filtering to adapt faster to larger
delay
* Improve logging of selection failures
* Detect clock interference from other processes
* Try to reopen message log (-l option) on cyclelogs command
* Fix sourcedir reloading to not multiply sources
* Fix tracking offset after failed clock step
* Drop support for NTS with Nettle < 3.6 and GnuTLS < 3.6.14
* Drop support for building without POSIX threads
- Update to version 4.6.1:
* Add ntsaeads directive to enable only selected AEAD algorithms
for NTS.
* Negotiate use of compliant NTS keys with AES-128-GCM-SIV AEAD
algorithm.
* Switch to compliant NTS keys if first response from server is
NTS NAK.
- Drop rcFOO symlinks for CODE16 (PED-266).
- Update to version 4.6:
* Add activate option to local directive to set activation threshold
* Add ipv4 and ipv6 options to server/pool/peer directive
* Add kod option to ratelimit directive for server KoD RATE support
* Add leapseclist directive to read NIST/IERS leap-seconds.list file
* Add ptpdomain directive to set PTP domain for NTP over PTP
* Allow disabling pidfile
* Improve copy server option to accept unsynchronised status instantly
* Log one selection failure on start
* Add offset command to modify source offset correction
* Add timestamp sources to ntpdata report
* Fix crash on sources reload during initstepslew or RTC initialisation
* Fix source refreshment to not repeat failed name resolving attempts
