Hi.  I have a few basic questions.

First, we have a particular piece of software that generates a lot of log 
entries for file deletes (successful & unsuccessful).  I'd like to limit what 
is actually captured by excluding that directory.

I'm thinking that I could add: -F dir!=/var/opt/xxx/xxx

Would that prevent logging from anything recursively from that directory and 
below or do I need to set rules to specifically exclude for each file (which I 
may do anyways)?  Is there a different/better means for doing this?

The second question is events resulting from running 'ls -al' as a normal user 
'su -' to root.  This is generating a failed syscall error for getxattr with an 
error code of 61 (no data available).  I'm assuming that this is because no 
extended attributes were set but, regardless, I'd like to avoid this.

I have the following rules that I think may be logging this but I'm not sure:

-a entry,always -F arch=b32 -S setxattr -S lsetxattr -S fsetxattr -S 
removexattr -S lremovexattr -S fremovexattr -k SYS_attribute
-a entry,always -F arch=b32 -S creat -S open -S openat -S truncate -S ftruncate

Would adding the following prevent these events from being logged or do I need 
to create a new rule(?): -F exit!=-61

Lastly, is there any benefit associated with ordering the rules in audit.rules, 
i.e., are they applied in the order they are read?

Thanks and let me know if need to provide additional information.

Aaron
