What’s new in this release

FIXES

Build

• Missing header npl_selinux.h in Makefile (noinst_HEADERS).

Libraries

• lib/container: docker API versions before v1.24 are deprecated, so 1.24 is set as the minimum version required.
• lib/sysfsparser: fix gcc warning: ‘crit_temp’ may be used uninitialized.
• lib/sysfsparser: better signature for function sysfsparser_getvalue.

Contrib (Icinga2)

• Fix Icinga2 config for check_clock by Lorenz Kästle. Previously the time reference value was evaluated only during the startup of Icinga 2 and therefore a fixed point in time. This change makes it a function which gets evaluated every time the check is executed.

ENHANCEMENTS

Plugin check_ifmount

• Add the cmdline switch -l|--list to list the mounted filesystems (same output as the mount command executed without options).

Plugin check_selinux

• New plugin check_selinux that checks if SELinux is enabled.

Package creation

• Add Linux Alpine 3.20 and drop version 3.17.
• Add Fedora 40, drop Fedora 38.

Documentation

• Fix typo.
• Add a link to discussion #147.
• Add a note on the Debian package nagios-plugins-contrib.
