https://git.stealer.net/cgit.cgi/user/sven/linux.git/atom?h=v3.72012-12-03T02:36:25Zmodsign: add symbol prefix to certificate list2012-12-03T02:36:25ZJames Hoganjames.hogan@imgtec.com2012-11-23T12:08:16Zurn:sha1:84ecfd15f5547c992c901df6ec14b4d507eb2c6e
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 kernel2012-10-10T09:31:22ZDavid Howellsdhowells@redhat.com2012-09-26T09:09:51Zurn:sha1:631cc66eb9eaa7296e303197ff1eb0f55e32b61d
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.
