Hi James,
The top patch here:
http://git.kernel.org/cgit/linux/kernel/git/dhowells/linux-fs.git/log/?h=modsign-pkcs7-2
allows demand loading of keys based on their SKID into a special keyring from
which they get erased after an arbitrary 3 minutes of existence. This key can
then be used to verify a signature instead of using the primary system keyring
used for module signature checking.
Building on this, a driver could have a SKID compiled into it which could then
be used to load a key for request_firmware() to use in verifying the blobs
that that driver requires.
David
