simplified mandatory access control module using the LSM framework
the module is an implementation of the MLS policy working mimicing Bel-Lapadula metholodgy a process with C clearense level could read files with C clearense and blow, and write to files with C clearense and above (0<=C<=3) file propertiy is stored as an extended attribute in the security name space a forked process will inherit his "father" clearense
use setfclass,getfclass to control the module the module is using lsm hooks and extendad attributes to implement the Bell-Lapadula module
its recommended to backup the kernel image before making any changes, with make bzimage the new image will be saved under arch/x86/boot/bzimage load you new image to boot/vmlinuz-x.x.xx/ and reboot the system
