No more report of quantity of rules successfully loaded

No more report of quantity of rules successfully loaded

Hi, I am running auditd-3.0.7-4 on an Alma Linux v8.8.

I know that for all of RHEL 6 and RHEL 7 variants that I worked with, to
include CentOS (not Stream) that after I rebooted a server or restarted the
auditd service (with -e 1 set) that I would 100% of the time get a report
in /var/log/messages about the quantity of rules that successfully loaded.

I could compare that to my unified rules file
(/etc/audit/rules.d/Unified.rules - for a reference) and strip out the
typical for auditd Control rules (-D, -e 1, -f 1, -b, -r, for examples) and
then assess if I had the full set of files loaded or not.

With this implementation of auditd, on version 3.0.7-4, I am not getting
those results anymore.
Am I looking in the wrong place, because for me this is important
information?

Yes, I know that I can also manually execute "auditctl -l  | wc -l" and get
that information  too, but I was wondering if this is planned or if I am
looking in the wrong place, or what to do.


Thanks,

It has never done that unless someone else has a patch they did not send 
upstream.

It has never done that. auditctl -D gives the output of auditctl -s as a 
convenience. But auditctl -s has never reported how many rules are loaded. I 
don't think the kernel has a counter. It has a variable for if any rules are 
loaded, but not the quantity.

It has never done that and is not planned.

Minor correction: there is a kernel variable (audit_n_rules) that counts
the number of syscall rules in place, but it isn't reported directly
outside the kernel.  This feeds the boolean (struct
audit_context)->dummy.

Obviously both of you are correct.  I am thinking about the number of rules
that load when not all of the rules load.  Specifically, it gives a line
number of the last line that loaded from the rules.  Which, for
troubleshooting purposes, I always put into a single file and sort
"alphabetically."

Also, I solved my own problem on the ruleset in the single file I was
working with on my VM.  I had 220 lines of syntax, and many of the lines
were auditd controls, because I do not know the exact term to label them;
things like -D -b -e -f and so on.

Thank you both, sorry for the disruption.
