Paul Moore eda61d32e8 NetLabel: introduce a new kernel configuration API for NetLabel
Add a new set of configuration functions to the NetLabel/LSM API so that
LSMs can perform their own configuration of the NetLabel subsystem without
relying on assistance from userspace.

Paul Moore 95d4e6be25 [NetLabel]: audit fixups due to delayed feedback
Fix some issues Steve Grubb had with the way NetLabel was using the audit
subsystem.  This should make NetLabel more consistent with other kernel
generated audit messages specifying configuration changes.

Paul Moore d15c345fe3 [NetLabel]: core NetLabel subsystem
Add a new kernel subsystem, NetLabel, to provide explicit packet
labeling services (CIPSO, RIPSO, etc.) to LSM developers.  NetLabel is
designed to work in conjunction with a LSM to intercept and decode
security labels on incoming network packets as well as ensure that
outgoing network packets are labeled according to the security
mechanism employed by the LSM.  The NetLabel subsystem is configured
through a Generic NETLINK interface described in the header files
included in this patch.
