Actually, I think security composition is such a difficult problem that we should not provide support for it via LSM. The LSMs can themselves implement and compose security models if needed, e.g. SELinux already does this with TE/RBAC/MLS and self-stacks the capabilities code for application compatibility (the latter could be done via a library and does not need to be stacked). I don't think arbitary composition of security models is a service that the Linux kernel should provide. - James -- James Morris <jmorris@private>  e.g. see chapter 24 of Amoroso's Fundamentals of Computer Security & the referenced papers on the topic.
