This is a resend of an earlier patch to dst_dev_event.  I've changed
it slightly by moving the input/output assignment into dst_ifdown.

To recap, this patch drops lingering IPsec references to a device that
is being unregistered.  The child processing in the GC is too late
since it never runs until the reference on the dst hits zero which
could take a long time for things like TCP connections.

The reason I've left the input/output assignment outside the loop is
because they aren't really necessary for the IPsec dst's, and if
it were in the loop then we'll have to do the same child processing
in ___dst_free as well.

I've tested this with an ESP/IPCOMP tunnel and I can confirm that it
does fix the problem.

Modifies the LSM netlink_send() hook so that it takes a struct sock
parameter.  SELinux will use this parameter to lookup the class of socket,
which was assigned during socket security initialization.

This patch moves the security_netlink_send() LSM hook after the user copy,
so that LSM modules can safely examine skb payload content.  For SELinux,
we need to look at the Netlink message type.

This patch regenerates the SELinux module headers to reflect new class
and access vectors definitions.  The size of the diff is misleading;
much of it is simply a change in the ordering of the automatically
generated definitions. The corresponding generation script has been
changed to ensure a stable order in the future.

The patch below fixes a race between sock_orphan() and
selinux_socket_sock_rcv_skb() which can lead to a null pointer deref oops
under heavy load.  The sk_callback_lock is used in the patch to 
synchronize access to the incoming socket's inode security state.

This patch has been under test in the Fedora kernel for over a month 
without incident.

I noticed that insert_resource() incorrectly handles the case of an
existing parent resource with the same ending address as a newly added
child.  This results in incorrect nesting, like the following:

	# cat /proc/ioports

	002f0000-002fffff : PCI Bus #48
	  00200000-002fffff : /pci@800000020000003
