audit in /selinux directory

["Camilo Y. Campo" <camilo@br.ibm.com>]

Hi All,

Some files in /selinux have a weird behavior on audit records... When I
try read (or write) some files with no read (or write) permission, I
can't get the audit record even when I watch the file.
 
Look at this example:
[root@alex tmp]# auditctl -w /selinux/disable 
[root@alex tmp]# cat /selinux/disable
cat: /selinux/disable: Invalid argument
[root@alex tmp]# ausearch -i -f /selinux/disable
----
type=PATH msg=audit(03/09/2007 16:23:01.340:29662) : item=0
name=/selinux/disable inode=13 dev=00:0e mode=file,200 ouid=root
ogid=root rdev=00:00 obj=system_u:object_r:security_t:s0 
type=CWD msg=audit(03/09/2007 16:23:01.340:29662) :  cwd=/tmp

comm=cat exe=/bin/cat subj=abat_u:abat_r:abat_t:s0-s15:c0.c1023
key=(null) 

The cat command failed and audit is saying "success". A bit strange for
me. Could anybody clarify this point for me, please?

Best Regards
