Description Philip Prindeville 2011-05-27 03:17:43 UTC

Description of problem:

Following the commit of #705427, systemd now generates the following messages at Debug level:

May 26 09:01:01 localhost /usr/sbin/crond[5136]: pam_systemd(crond:session): Moving new user session for root into control group /user/root/67.
May 26 09:01:01 localhost /USR/SBIN/CROND[5136]: pam_systemd(crond:session): Moving remaining processes of user session 67 of root into control group /user/root/master.

as a consequence of authpriv.* being logged to /var/log/secure.  The fix is to raise this to "authpriv.info" instead.


Version-Release number of selected component (if applicable):

5.7.9-2.fc15

How reproducible:

Not necessary... a running f15 system should do this by default.

Steps to Reproduce:
1.
2.
3.
  
Actual results:

Lots of the above logs (one every hour).

Expected results:

Nothing, as the above log messages are non-exceptional indications (i.e. normal behavior).

Please wait for Lennart's response before doing this change to the default rsyslog.conf.

Looking at that patch, it doesn't seem to touch rsyslog... in fact, it adds a gating variable to calling syslog() so that debugging messages can be turned off altogether (which is a bit odd, since the logging level also functions as the gating variable).

Correct.

Yes. The debug messages will be off by default. It's similar to other PAM modules in this regard.

True, but is more efficient to stop emitting the messages altogether, than to wake syslog only to have them discarded (in the usual configuration).

Comment 4 Michal Schmidt 2011-06-15 22:01:37 UTC

systemd-26-4.fc15, which I have just submitted to updates-testing, does not log debug messages by default anymore.

I recommend WONTFIX for this bug.
