*	modsign: add symbol prefix to certificate list	James Hogan	2012-12-03	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Add the arch symbol prefix (if applicable) to the asm definition of modsign_certificate_list and modsign_certificate_list_end. This uses the recently defined SYMBOL_PREFIX which is derived from CONFIG_SYMBOL_PREFIX. This fixes the build of module signing on the blackfin and metag architectures.

*	MODSIGN: Provide module signing public keys to the kernel	David Howells	2012-10-10	1	-0/+113
	Include a PGP keyring containing the public keys required to perform module verification in the kernel image during build and create a special keyring during boot which is then populated with keys of crypto type holding the public keys found in the PGP keyring. These can be seen by root: [root@andromeda ~]# cat /proc/keys 07ad4ee0 I----- 1 perm 3f010000 0 0 crypto modsign.0: RSA 87b9b3bd [] 15c7f8c3 I----- 1 perm 1f030000 0 0 keyring .module_sign: 1/4 ... It is probably worth permitting root to invalidate these keys, resulting in their removal and preventing further modules from being loaded with that key.
