Resolving syscall numbers
by Steve
This may not be appropriate for this list, if it isn't I apologize and
you may ignore it.
Is there an quick way to resolve the syscall number that auditd returns
within a message to a syscall name? (ie. 5->open)?
I am programming in C, if that helps.
Thanks,
Steve

Possibly wrong audit messages
by Glauber de Oliveira Costa
Hi,
I'm in a FC5 box, and tryied to shoot an setsebool command as
secadm_r:SystemHigh (mls policy)
Instead of an audit message identifying the set operation, I'm getting 81 AVC
messages (81 is the number of booleans present in /selinux/booleans/)
indicating a success. Such a large number of messages makes the correct
information hard to find, IMHO. This does not seem to be the right behaviour
to me.
A typical message looks like this:
type=AVC msg=audit(1149411239.670:6462): avc: granted { setbool }
for pid=3460 comm="setsebool" scontext=root:secadm_r:secadm_t:s15:c0.c255
tcontext=system_u:object_r:security_t:s15:c0.c255 tclass=security
If this is really the expected behaviour, sorry for the bogus report.

audit-current git
by Robert Giles
Howdy folks - this isn't really an audit related question, but where do
all the [PATCH git] fixes end up after being posted to the list?
I'm looking at http://www.kernel.org/git/, and the last change to the
"audit-current" git tree was four weeks ago (but there have been quite a
few [PATCH git] postings to the list since then).
Also - the "audit-current" that's up there now (based on 2.6.17-rc3) works
great on SuSE 10.1 + audit-1.2.2 with filesystem watches (THANKS!!!).

Monitoring events
by Steve
I have the program adding rules to Audit now. Thank you for your help.
I also have my program monitoring the output from auditd (via the
dispatch option in auditd.conf).
Ideally, I would like to only capture (or parse) events pertaining to
rules I have created (since other system processes are using auditd as
well). Is there's any kind of identifier that ties events to rules?
Thank you again,
Steve

watching files/directories with audit the contains turkish characters in file/directory name
by Evren Kalayciklioglu
I want to monitor some specific file with audit. These
files' names mostly includes Turkish characters. When
i tried the program, for including Turkish characters,
log for these files is unreadable. I can change all
these files' names but my boss does not accept this.
He wants to watch with Turkish characters and the
output file is correct and readable for Turkish
according to him.
So, i am thinking to change the source if there is
definite character codes. what i want to do that
change the valid character code to unicode UTF-8 or
add unicode UTF-8.
Is it possible? or not? If it is possible, which file
is interested what i want to do in source code?
Thanks a lot.

Adding rules
by Steve
I am attempting to create a c program that can add rules to the audit
sub-system and monitor the resulting events. I have read through the
code in libaudit.h, audit.h, audit.c, and auditsc.c as well as several
man pages pertaining to audit and extended searching of the web.
I am trying to add a rule using audit_add_rule() so audit will "watch" a
file. The first problem is that there doesn't seem to be an appropriate
field under the "Rule Fields" section of audit.h. The second is that
the value must be an integer...
I have succeeded in adding the rule from the command-line using auditctl.
I would appreciate any help you can offer,
Steve
I am using: audit-1.2.3-1 and glibc-kernheaders-3.0-37

cups userspace -- trusted programs?
by Michael C Thompson
Hey all,
I'm wondering if the intent of the cups userspace tools are to be
trusted programs? Specifically I'm curious about cupsaccept, cupsreject,
cupsenable and cupsdisable. The reason I ask is because if they are
supposed to be trusted programs, they don't generate unique audit
messages like other programs.
Personally, I think these tools should generate messages since they are
a source for leaking information, and therefore should be restricted to
administrators.
Thanks,
Mike
