(from [link this mailing list post])

To add a new permission to SELinux: 1) checkout a copy of the refpolicy from 2) cd refpolicy/policy/flask/ 3) edit access_vectors and add your definition 4) run make 5) run make LINUX_D=/path/to/linux-2.6 tokern to push the kernel headers to your kernel tree 6) run make LIBSELINUX_D=/path/to/libselinux tolib to push the libselinux headers to your libselinux tree.

Then you can generate patches against policy, kernel, and libselinux.

There is also the backward compatibility issue - we must not break akpm's system if he boots a new kernel on an existing distro that lacks new policy.
