To add a new permission to SELinux:
1) checkout a copy of the refpolicy from oss.tresys.com or build prep the rawhide selinux policy src rpm
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.
