This fixes the problem of not receiving packets in the Xen bridging
environment.  The Xen script sets the device's MAC address to
FE:FF:FF:FF:FF:FF and puts the device in promiscuous mode.  The
firmware had problem receiving all packets in this configuration.

New firmware and setting the PROM_VLAN bit when in promiscuous mode
will fix this problem.

The audit_enabled flag is used to signal when syscall auditing is to be
performed.  While NetLabel uses a Netlink interface instead of syscalls, it is
reasonable to consider the NetLabel Netlink interface as a form of syscall so
pay attention to the audit_enabled flag when generating audit messages in
NetLabel.

Now that labeled IPsec makes use of the peer_sid field in the
sk_security_struct we can remove a lot of the special cases between labeled
IPsec and NetLabel.  In addition, create a new function,
security_skb_extlbl_sid(), which we can use in several places to get the
security context of the packet's external label which allows us to further
simplify the code in a few places.

This patch does a lot of cleanup in the SELinux NetLabel support code.  A
summary of the changes include:

* Use RCU locking for the NetLabel state variable in the skk_security_struct
  instead of using the inode_security_struct mutex.
* Remove unnecessary parameters in selinux_netlbl_socket_post_create().
* Rename selinux_netlbl_sk_clone_security() to
  selinux_netlbl_sk_security_clone() to better fit the other NetLabel
  sk_security functions.
* Improvements to selinux_netlbl_inode_permission() to help reduce the cost of
  the common case.

The CIPSOv4 engine currently has MLS label limits which are slightly larger
than what the draft allows.  This is not a major problem due to the current
implementation but we should fix this so it doesn't bite us later.

The CIPSOv4 translated tag #1 mapping does not always return the correct error
code if the desired mapping does not exist; instead of returning -EPERM it
returns -ENOSPC indicating that the buffer is not large enough to hold the
translated value.  This was caused by failing to check a specific error
condition.  This patch fixes this so that unknown mappings return
-EPERM which is consistent with the rest of the related CIPSOv4 code.

While the original CIPSOv4 code had provisions for multiple tag types the
implementation was not as great as it could be, pushing a lot of non-tag
specific processing into the tag specific code blocks.  This patch fixes that
issue making it easier to support multiple tag types in the future.

Currently the CIPSOv4 engine does not do any sort of checking when a new DOI
definition is added.  The tags are still verified but only as a side effect of
normal NetLabel operation (packet processing, socket labeling, etc.) which
would cause application errors due to the faulty configuration.  This patch
adds tag checking when new DOI definition are added allowing us to catch these
configuration problems when they happen.

Right now the NetLabel code always jumps into the CIPSOv4 layer to determine if
a CIPSO IP option is present.  However, we can do this check directly in the
NetLabel code by making use of the CIPSO_V4_OPTEXIST() macro which should save
us a function call in the common case of not having a CIPSOv4 option present.

The existing netlbl_lsm_secattr struct required the LSM to check all of the
fields to determine if any security attributes were present resulting in a lot
of work in the common case of no attributes.  This patch adds a 'flags' field
which is used to indicate which attributes are present in the structure; this
should allow the LSM to do a quick comparison to determine if the structure
holds any security attributes.

Example:

 if (netlbl_lsm_secattr->flags)
	/* security attributes present */
 else
	/* NO security attributes present */
