From a239b032a018c49fa570c6568f62e858ce738ba2 Mon Sep 17 00:00:00 2001 From: Christian Breunig Date: Sun, 21 Jan 2024 08:29:52 +0100 Subject: ntp: T5692: add support to configure leap second behavior * set service ntp leap-second [ignore|smear|system|timezone] Where timezone is the new and old default resulting in adding "leapsectz right/UTC" to chrony.conf. The most prominent new option is "smear" which will add leapsecmode slew maxslewrate 1000 smoothtime 400 0.001 leaponly to chrony. See https://chrony-project.org/doc/4.3/chrony.conf.html leapsecmode for additional information (cherry picked from commit 7ae064bab0010dff8827a0ed5e1239d2778dc7c1) --- data/templates/chrony/chrony.conf.j2 | 10 +++++++++ interface-definitions/service_ntp.xml.in | 36 +++++++++++++++++++++++++++---- smoketest/scripts/cli/test_service_ntp.py | 33 +++++++++++++++++++++++----- src/conf_mode/service_ntp.py | 4 ++-- 4 files changed, 72 insertions(+), 11 deletions(-) diff --git a/data/templates/chrony/chrony.conf.j2 b/data/templates/chrony/chrony.conf.j2 index d02fbf71d..e3f078fdc 100644 --- a/data/templates/chrony/chrony.conf.j2 +++ b/data/templates/chrony/chrony.conf.j2 @@ -21,7 +21,17 @@ ntsdumpdir /run/chrony pidfile {{ config_file | replace('.conf', '.pid') }} # Determine when will the next leap second occur and what is the current offset +{% if leap_second is vyos_defined('timezone') %} leapsectz right/UTC +{% elif leap_second is vyos_defined('ignore') %} +leapsecmode ignore +{% elif leap_second is vyos_defined('smear') %} +leapsecmode slew +maxslewrate 1000 +smoothtime 400 0.001024 leaponly +{% elif leap_second is vyos_defined('system') %} +leapsecmode system +{% endif %} user {{ user }} diff --git a/interface-definitions/service_ntp.xml.in b/interface-definitions/service_ntp.xml.in index 65a45d7a1..c057b62b5 100644 --- a/interface-definitions/service_ntp.xml.in +++ b/interface-definitions/service_ntp.xml.in @@ -9,6 +9,38 @@ 900 + #include + #include + #include + #include + + + Leap second behavior + + ignore smear system timezone + + + ignore + No correction is applied to the clock for the leap second + + + smear + Correct served time slowly be slewing instead of stepping + + + system + Kernel steps the system clock forward or backward + + + timezone + Use UTC timezone database to determine when will the next leap second occur + + + (ignore|smear|system|timezone) + + + timezone + Network Time Protocol (NTP) server @@ -56,10 +88,6 @@ - #include - #include - #include - #include diff --git a/smoketest/scripts/cli/test_service_ntp.py b/smoketest/scripts/cli/test_service_ntp.py index 5e385d5ad..ae45fe2f4 100755 --- a/smoketest/scripts/cli/test_service_ntp.py +++ b/smoketest/scripts/cli/test_service_ntp.py @@ -1,6 +1,6 @@ #!/usr/bin/env python3 # -# Copyright (C) 2019-2023 VyOS maintainers and contributors +# Copyright (C) 2019-2024 VyOS maintainers and contributors # # This program is free software;
