I'll be happy to help out; I'd consider my self neutral in this space
not having worked with any of the LSM out there. I do think we need to
be somewhat critical to what we accept; we should at least be able to
filter out "pretend security" somehow. (this is not the same as saying
that you're bad if you only provide a limited security, in the
contrary, I strongly believe in simple pieces. What I mean is that we
should be critical to things that appear/claim to be strong but are
not).
Secondly, we should make sure that no new holes are added (the original
SMACK series suffered from this, Al Viro helped getting that reviewed
bigtime).
In addition we probably should strive to getting some sort of rough
"this is sort of where we draw the line" guideline set up, just to keep
things more objective.
(Oh and of course, if a security module is deeply involved in another
kernel subsystem, say networking or the VFS, very obviously we should
consult and listen to the respective maintainers of that subsystem; LSM
is not there to be a big hook to bypass the process of well maintained
subsystems)
