NetLabel audit messages

[Paul Moore <paul.moore@hp.com>]

In order to meet certain certification requirements, the NetLabel kernel
subsystem needs to write a small number of audit messages.  From what I
can tell this is going to require a new message type as well as
agreement on the content and formatting of the messages themselves.  Am
I missing anything?

For the new message type, I would like to propose the following:

 #define AUDIT_NLBL 1480


For the messages themselves, here is what I was thinking:

 "netlabel: <protocol> op=<operation> pid=<pid> tty=<tty> comm=<name>
            exe=<path> uid=<uid> auid=<auid> euid=<euid> suid=<suid>
            fsuid=<fsuid> gid=<gid> egid=<euid> sgid=<suid>
            fsgid=<fsuid> [<cipsov4 extras>|<managment extras>]"

 <protocol>         => cipsov4 | unlabeled | management

 <operation>        => (for protocol == cipsov4) add | del
                       (for protocol == unlabeled) accept | deny
                       (for protocol == management) map_add | map_delete

 <cipsov4 extras>   => doi=<DOI #> type=<DOI type>
  <DOI #>    => (CIPSO DOI value, i.e. unsigned 32-bit value)
  <DOI type> => std | pass

 <mangement extras> => domain=<domain> protocol=<protocol> [doi=<DOI #>]
  <domain>   => "(domain string, i.e. foo_t)" | default

Comments and suggestions are welcome.
