This is the sixth general posting of the newest version of the
AppArmor security module it has been rewritten to use the security_path
hooks instead of the previous vfs approach.  The current implementation
is aimed at being as semantically close to previous versions of AppArmor
as possible while using the existing LSM infrastructure.

Development is on going and
improvements to file, capability, network, resource usage and ipc mediation
are planned.

With this submission we believe AppArmor is ready for inclusion into
the kernel.

_Issues NOT specifically addressed_
* The d_namespace_path function still manually strips the " (deleted)"
  string that __d_path appends.  A fix to __d_path is being pursued
  independently of the AppArmor submission.
