Description Pierre Juhen 2017-09-03 07:24:53 UTC
Description of problem:
Message : 
auditd[1127]: Error setting audit daemon pid (Invalid argument)

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

How reproducible:

No impact.

Comment 1 Steve Grubb 2017-09-13 16:31:14 UTC
This appears to be related to 


At line 471 in audit.c, it now checks for !pid and returns -EINVAL. Setting the pid to 0 is exactly how auditing is supposed to end.

Comment 2 Laura Abbott 2017-09-13 17:08:52 UTC
Paul, was this change intended?

Comment 3 Paul Moore 2017-09-13 17:12:47 UTC
What kernel version are we talking about?

 # uname -r

Comment 4 Pierre Juhen 2017-09-13 18:45:08 UTC

My kernel version is :


The problem was already present in previous  4.12 versions.


Comment 5 Paul Moore 2017-10-02 15:20:33 UTC
Since this surely isn't Fedora specific, and because it may be some time before I can address this, let's create an upstream issue tracker.

Comment 6 Paul Moore 2018-01-28 13:59:22 UTC
FYI: this is fixed upstream in the commit below and should be v4.15 which I expect to be released later today.

Laura, is F26 going to see v4.15?  If so, I'm not sure it is worth backporting this.

    audit: Allow auditd to set pid to 0 to end auditing
    The API to end auditing has historically been for auditd to set the
    pid to 0. This patch restores that functionality.

Comment 7 Laura Abbott 2018-01-28 14:04:37 UTC
Yes, F26 (and F27) will be getting 4.15, probably by the end of February assuming standard kernel timing holds.

Comment 8 Paul Moore 2018-01-28 14:21:21 UTC
Okay, thank you.  I'm going to close this as UPSTREAM, if anyone has a strong objection, speak your mind now.
