chrony (4.8-4ubuntu1) stonking; urgency=medium
* Merge with Debian unstable (LP: #2154097). Remaining changes:
- Set -x as default if unable to set time (e.g. in containers) (LP #1589780)
Chrony is a single service which acts as both NTP client (i.e. syncing the
local clock) and NTP server (i.e. providing NTP services to the network),
and that is both desired and expected in the vast majority of cases.
But in containers syncing the local clock is usually impossible, but this
shall not break the providing of NTP services to the network.
To some extent this makes chrony's default config more similar to 'ntpd',
which complained in syslog but still provided NTP server service in those
cases.
+ debian/chrony.service: allow the service to run without CAP_SYS_TIME
+ d/control: add new dependency libcap2-bin for capsh (usually
installed anyway, but make them explicit to be sure).
+ d/chrony.default: new option SYNC_IN_CONTAINER to not fall
back (Default off)
+ d/chronyd-starter.sh: wrapper to handle special cases in
containers and if CAP_SYS_TIME is missing. Effectively allows
running the NTP server in containers on a default installation
and avoid failing to sync time (or if allowed to sync, avoid
multiple containers fighting over it by accident).
+ d/chrony.install: Make chrony-starter.sh available on install.
+ d/docs, d/README.container: Provide documentation about the
handling of this case.
- d/rules, d/chrony.examples: Ship restricted service as an example
not installed to the system for use. (See LP #2051028)
- d/chrony.conf: remove Debian NTP pool and Document non-NTS sources from
DHCP (LP #2115565)
- Install Ubuntu NTP sources in
/etc/chrony/sources.d/ubuntu-ntp-pools.sources, gated on a low priority
(default yes) debconf question (LP #2048876):
+ d/templates: Add debconf question to customize installation of
/etc/chrony/sources.d/ubuntu-ntp-pools.sources
+ d/chrony.install, d/ubuntu-ntp-pools.sources: Install
ubuntu-ntp-pools.sources in /usr/share/chrony
+ d/control: add dependency on debconf
+ d/postinst: handle Ubuntu pools via debconf and ucf
+ d/postrm: handle Ubuntu pools via debconf and ucf
+ d/NEWS: Add information about default time sources moving out from
chrony.conf to /etc/chrony/sources.d/ubuntu-ntp-pools.sources.
+ d/chrony.config: debconf script to handle Ubuntu pools
+ d/t/control, d/t/default-ubuntu-sources-behavior: new test to check the
debconf behavior
- Use Ubuntu NTS servers by default (LP #2084585):
+ d/conf.d/ubuntu-nts.conf: refer to the CA used to sign the NTS bootstrap
server
+ d/nts-bootstrap-{,staging}-ubuntu.crt: CA certificate for the NTS
bootstrap servers
+ d/chrony.install: install the NTS bootstrap CAs
+ d/ubuntu-ntp-pools.sources: use NTS by default
+ d/t/default-ubuntu-sources-behavior: update tests for NTS support
+ d/NEWS: add news entry about the NTS change
- d/chrony.service: Allow real chronyd to send READY=1 via sd_notify in
place of the chronyd-starter.sh wrapper.
- d/control: Recommends: networkd-dispatcher (LP #2132159)
- configure: switch sed separator from % to # to cope with dpkg
- d/t/upstream-simulation-test-suite: revert update of clknetsim done in
4.8-1 which redefines __open64_2 and breaks armhf build
* Dropped:
- d/t/helper-functions: show some logs in case of failure
[In 4.8-3]
- d/usr.sbin.chronyd: adjust apparmor rule so that chronyd is also allowed
to access subdirectories of /run/chrony
[In 4.8-3]
