[RFC 1/1] NetLabel: add audit support for configuration changes

[Linda Knippers]

Thanks for sending the audit records.

>  # netlabelctl unlbl accept on
> 
> type=UNKNOWN[1406] msg=audit(1159362394.806:420): netlabel: module=unlbl 
> action=accept auid=0 uid=0 euid=0 tty=pts0 pid=6711 comm="netlabelctl"  
> exe="/usr/local/sbin/netlabelctl"
> 
>  (there is also an audit message for "unlbl accept off" which changes
>   "action=accept" to "action=deny")

One nit-picky comment is that once the user-space tools know about the
message type and insert "MAC_UNLBL_ACCEPT" as the type, the module=
and action= fields will be somewhat redundant.  I think the same is
true for the other types of audit records.  You could omit the switch
statement in netlbl_audit_start_common() and shorten the audit records
if we rely on the audit record type to provide that module/action information.
