[Labeled-nfs] Interface for DOI mapping

[Dave Quigley]

Hello,
    With help from Neil I have the actual daemon code working for DOI
translations. Now I have to come up with an interface for allowing an
LSM to specify its translations. Either in the form of a separate
library or in the daemon code itself I intend to dlopen a shared library
and make calls into it. The question is what functionality do we want
here and where should it be placed. 

In the long run it would be nice to have a server which maintains the
mappings for all of the clients in its domain similar to kerberos.
However the client also needs to be able to operate without such a
server. 

If you have suggestions for this feel free to make them now while I am
still designing this.
