Most of the support for trusted boot already exists in Fedora but all of the pieces have never been put together. The goal of this feature is to allow users to boot a kernel, and after it is booted to know that the kernel they are running is the kernel they expected to have running.
Benefit to Fedora
Security minded users have no way of knowing if their kernel is the expected kernel. They have no way of knowing if the system under them has been trojaned. The point of this feature is to give users a method to verify that the system that booted was the system they expected to boot.
Changes are expected to be needed in grub, tpmutils, trousers, and possibly in the kernel configuration.
How To Test
- At the moment testing isn't well defined. Ultimately tests will involve users with TPM enabled hardware to be able to verify the same kernel booted they expected or a different kernel booted than they expected.
- FIXME--more details needed
No one will notice a change unless they specifically configure their system. There are no planned default changes.
The grub changes, and possibly the intel TXT support are requirements which I may not be able to control but which may cause the feature to fail to complete.
None necessary, if it doesn't work, it wasn't going to be default anyway. Users just won't be able to use it.
- FIXME--Nothing et.
- FIXME---No good note yet as there is no documentation. There is no upstream.
