systrace kernel policy question

Hello everyone:

Hopefully I didn't post this question to the incorrect group, and I
apologize if I have done so.  I'm doing some research on systrace and in
reading through Neils Provos' white paper I've learned that systrace has
an in-kernel policy for a number of system calls separate of the 
userland policies.  Unfortunately, it doesn't appear that the paper has
a listing of the various calls, which is what I'm searching for.  I've been 
crusing through the source code trying to locate a listing of these policies 
in some form, but have been unable to find the file that contains any 
reference to them.  Does anyone have knowledge of the location(s) 
and/or name(s) of the file(s) that contains these?
  
Thank you in advance for your assitance.

Roger
