Package: nagios-plugins-contrib
Version: 17.20161211
check_libs doesn't report processes that have mmaped files which have
been deleted in the meantime.
Importantly that includes libraries that have been upgraded.
To reproduce on buster with systemd (but obviously applies to other
processes as well):
apt install --reinstall libseccomp2
# /usr/lib/nagios/plugins/check_libs
No upgraded libs linked in running processes
This is caused by on overly aggressive optimization introduced in the
lsof-speedup patch here:
https://salsa.debian.org/nagios-team/pkg-nagios-plugins-contrib/commit/cd5eacf4faa9f81ec82d57befd44bf6d623c7e26#24f6022115d4e658ca493136b4c17be4fc7e0537_8_8
When reverting that patch to (removing -a +L1)
> my $LSOF = '/usr/bin/lsof -nPF0';
it correctly reports systemd processes
# /usr/lib/nagios/plugins/check_libs
The following processes have libs linked that were upgraded: root:
(sd-pam) (544), systemd (1, 543), [...]

When running this on buster with package 27.20200511+1:
# /usr/lib/nagios/plugins/check_libs
The following processes have libs linked that were upgraded:
systemd-logind (662), systemd (11284, 11282)
I guess this was fixed with 27.20200511+1 by:
* [45d41ae] check_libs is now a symlink to check_libs_ng
Yes, this report doesn't apply to the new implementation.
Closing it now.
Felix
