Simply wrapping the system calls isn't going to get a CAPP (or C2)
compliant audit implementation. It also isn't how the "unified security
hooks" (aka LSM, Linux Security Modules) are working.

SGI is working towards a CAPP compliant audit implementation under the LSM
framework, I'd suggest that you head over to http://lsm.immunix.org/ for
more details on LSM.
