It can also operate as an NTPv4 (RFC 5905) \ +server and peer to provide a time service to other computers in the \ +network. \ +\ +It is designed to perform well in a wide range of conditions, \ +including intermittent network connections, heavily congested \ +networks, changing temperatures (ordinary computer clocks are \ +sensitive to temperature), and systems that do not run continuously, or \ +run on a virtual machine. \ +\ +Typical accuracy between two machines on a LAN is in tens, or a few \ +hundreds, of microseconds; over the Internet, accuracy is typically \ +within a few milliseconds. With a good hardware reference clock \ +sub-microsecond accuracy is possible. \ +\ +Two programs are included in chrony: chronyd is a daemon that can be \ +started at boot time and chronyc is a command-line interface program \ +which can be used to monitor chronyd's performance and to change \ +various operating parameters whilst it is running. \ +\ +This recipe produces two binary packages: 'chrony' which contains chronyd, \ +the configuration file and the init script, and 'chronyc' which contains \ +the client program only." + +HOMEPAGE = "https://chrony.tuxfamily.org/" +SECTION = "net" +LICENSE = "GPLv2" +LIC_FILES_CHKSUM = "file://COPYING;md5=751419260aa954499f7abaabaa882bbe" + +SRC_URI = "https://download.tuxfamily.org/chrony/chrony-${PV}.tar.gz \ + file://chrony.conf \ + file://chronyd \ + file://arm_eabi.patch \ +" + +SRC_URI:append:libc-musl = " \ + file://0001-Fix-compilation-with-musl.patch \ +" +SRC_URI[sha256sum] = "273f9fd15c328ed6f3a5f6ba6baec35a421a34a73bb725605329b1712048db9a" + +DEPENDS = "pps-tools" + +# Note: Despite being built via './configure; make; make install', +# chrony does not use GNU Autotools. +inherit update-rc.d systemd + +# Add chronyd user if privdrop packageconfig is selected +inherit ${@bb.utils.contains('PACKAGECONFIG', 'privdrop', 'useradd', '', d)} +USERADD_PACKAGES = "${@bb.utils.contains('PACKAGECONFIG', 'privdrop', '${PN}', '', d)}" +USERADD_PARAM:${PN} += "${@bb.utils.contains('PACKAGECONFIG', 'privdrop', '--system -d / -M --shell /bin/nologin chronyd;', '', d)}" + +# Configuration options: +# - For command line editing support in chronyc, you may specify either +# 'editline' or 'readline' but not both. editline is smaller, but +# many systems already have readline for other purposes so you might want +# to choose that instead.
