parentMODSIGN: Automatically generate module signing keys if missing (diff)
MODSIGN: Provide module signing public keys to the kernel
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.
