This is a request for comments for a new Integrity Based Access
Control(IBAC) LSM module which bases access control decisions

(Hopefully this will help clarify the interaction between an LSM
module and LIM module.)

OK, between this and the additional LIM hooks I didn't notice in an earlier
patch, we're starting to see the API. The only problem is that although
it may be the right API for *your* code, I suspect it's a non-starter without
a discussion about whether it's the right *generic* API for an LIM (which will
require at least one dramatic bun fight about what "Integrity" means).

Casey's earlier message suggested this too. 'Integrity' here in
particular does not mean online integrity guarantees through, i.e.,
information flow control. So perhaps instead of 'integrity' we should
make sure to always say 'integrity measurement'. Of course then there
is already the 'integrity measurement architecture' which is only one
implementation of a LIM module, right? So it would need to be renamed
to TIMA (TPM-enabled IMA) or something I guess.
