Introduction to TOMOYO
The fundamental concept of TOMOYO Linux is "tracking process invocation history". TOMOYO Linux splits domains using "process invocation history" and the process transits to a different domain whenever execution of a program (i.e. do_execve()) is requested. By transiting to a different domain whenever execution of a program is requested, each domain will have the minimal permissions that are essential for processes in that domain to do their roles.

Patch the kernel source:
patch -p1 -i ../sched-cfs-v2.6.22.9-v22.patch && patch -p1 -i ccs-patch-2.6.22.txt
Compile and install a new TOMOYO aware kernel. Ensure you enable the TOMOYO features.
2.6.23 Kernel
Apply the TOMOYO patches to the kernel source:
for i in `cat patches/series`; do patch -p1 < patches/$i; done
