The SELinux kernel code unhooks itself from the kernel code paths if you use SELINUX=disabled in /etc/selinux/config (and never hooks at all if you use selinux=0 in grub.conf). So the kernel code is not actively executed when disabled.
That, at least, is somewhat a relief.
The userland code should be doing an is_selinux_enabled() check before doing SELinux processing, and skipping it if disabled. If not, then that's a bug.
I'm sure it's not the only one. :-)
If you want to be able to remove the libraries (e.g. libselinux), someone would need to rework the users of the libraries to use dlopen()
How about implementing a library with just appropriate stubs?
and friends to dynamically lookup the selinux symbols and fall back to non-selinux behavior if not present rather than linking against libselinux at build time. Doable, but at a cost (in time to rework all calling code, and in runtime for the dlopen). If you want to make that happen, patches that implement such changes are the best way...
