The res field has a value of 1 instead of either success or fail

The res field has a value of 1 instead of either success or fail

Hello,

According to this [1] and the definition of the res field here [2], the res field should have a value of either success or fail.

Here are some logs I generated on Debian:

type=USER_START msg=audit(1464013671.525:405): pid=3569 uid=0 auid=1000 ses=7 msg='op=PAM:session_open acct="root" exe="/usr/bin/sudo" hostname=? addr=? terminal=/dev/pts/1 res=success'
type=CONFIG_CHANGE msg=audit(1464013671.541:406): auid=1000 ses=7 op="add rule" key=(null) list=4 res=1
type=USER_END msg=audit(1464013671.549:407): pid=3569 uid=0 auid=1000 ses=7 msg='op=PAM:session_close acct="root" exe="/usr/bin/sudo" hostname=? addr=? terminal=/dev/pts/1 res=success’

As you can see, there is a res field which value is 1.

Is it because my auditd is outdated? Is there a missing res field which is purely numeric (just like the fields called fp [3])?

As Steve said in previous emails, it is possible and it might be fixed already. I’ll try to find out if I get similar logs with the latest auditd (2.6.5) on CentOS 6.8-i386 later.

Cheers!

I confirm that it is possible to generate a type=CONFIG_CHANGE record with a res=1 field on CentOS 6.8 with auditd v2.6.5.

No. There is inconsistency because different people do it their way without 
regard for anyone who is trying to make sense of the audit trail. This is why 
I have published so many specifications. I want to point to the docs and say 
you have to conform. And this is also why I want to write a validation suite. 
We need to find all the outliers and fix them.
