[Bug 1703987] [NEW] New style permitnonkernelfacility imklog option inside module() doesn't work

[Andreas Hasenack]

Public bug reported:

artful 8.16.0-1ubuntu5 (which is way behind upstream and debian, btw)

There are two ways to load the imklog module and pass it an option
(PermitNonKernelFacility in this case).

a) legacy
$ModLoad imklog
$KLogPermitNonKernelFacility on


b) "new style", also referred to as "v6+":
module(load="imklog" permitnonkernelfacility="on")

For a while the ubuntu package was using a mix: loading the module with
the new style, but setting the option via the legacy method. In bug
#1531622 this was fixed for yakkety+.

Problem is, upstream isn't honouring the new style option setting due to
a bug of its own: https://github.com/rsyslog/rsyslog/issues/477

With the legacy config:
#module(load="imklog" permitnonkernelfacility="on")
$ModLoad imklog
$KLogPermitNonKernelFacility on

I get kernel messages in /var/log/syslog:
root at nsn7:~# grep andreas-was-here /var/log/syslog
root at nsn7:~# echo andreas-was-here > /dev/kmsg
root at nsn7:~# grep andreas-was-here /var/log/syslog
Jul 12 16:46:33 nsn7 kernel: [27774.476193] andreas-was-here
root at nsn7:~#

But with this new v6 config style:
module(load="imklog" permitnonkernelfacility="on") # provides kernel logging support
#$ModLoad imklog
#$KLogPermitNonKernelFacility on

The text doesn't show up in /var/log/syslog. That's the upstream bug.
