+SELINUX SUPPORT
+===============
+
+The security class "key" has been added to SELinux so that mandatory access
+controls can be applied to keys created within various contexts. This support
+is preliminary, and is likely to change quite significantly in the near future.
+Currently, all of the basic permissions explained above are provided in SELinux
+as well; SE Linux is simply invoked after all basic permission checks have been
+performed.
+
+Each key is labeled with the same context as the task to which it belongs.
+Typically, this is the same task that was running when the key was created.
+The default keyrings are handled differently, but in a way that is very
+intuitive:
+
+ (*) The user and user session keyrings that are created when the user logs in
+ are currently labeled with the context of the login manager.
+
+ (*) The keyrings associated with new threads are each labeled with the context
+ of their associated thread, and both session and process keyrings are
+ handled similarly.
+
+Note, however, that the default keyrings associated with the root user are
+labeled with the default kernel context, since they are created early in the
+boot process, before root has a chance to log in.
