4224dfbd8SPaul Moore  * SELinux must keep a mapping of network nodes to labels/SIDs.  This
5224dfbd8SPaul Moore  * mapping is maintained as part of the normal policy but a fast cache is
6224dfbd8SPaul Moore  * needed to reduce the lookup overhead since most of these queries happen on
7224dfbd8SPaul Moore  * a per-packet basis.
