What do you mean by secure IPC?
As I understand it, presently the memory for the message queue is shared based
on user and group ownership of the process. By "secure IPC" is meaning a
security mechanism that provides a more fine granularity of specifying who
are allowed to send (or receive) messages... and maby also a way to resolve
the question of "Can I trust the message I received?"
I think the gnumach (sorry for the typo in my last e-mail) concept, fixes
the sending and receiving permission problem. See the gnumach
documentation and source code.
