    Hi,

I'm trying to start a quick project to evaluate the performance
implications of adding security checks during read/write/seeks.  I'd like
to use LSM for this, but I'm having a hard time figuring out what I need
to get up and running using it.

If I have a Debian installation, grab the stock 2.4.20 kernel from
kernel.org, and use the latest stable 2.4 patch from lsm.immunix.org, is
that sufficient to write a kernel module which can provide an
implementation for LSM's file_permission hook?

Do I need to also pick up the Traditional Super User module or an SELinux
implementation?

Does anyone have recommendations for howtos or guides to getting started?

Thanks,
Everett
