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 patches to the kernel source:

for i in `cat patches/series`; do
    patch -p1 < patches/$i;
done

Compile and install a new TOMOYO aware kernel. Ensure you enable the TOMOYO features. Go to "Security options" screen and unselect "Default Linux Capabilities", "Root Plug Support", "NSA SELinux Support" and select "TOMOYO Linux support".
