| |
Instead of allowing public keys, with certificates signed by any key on the system trusted keyring, to be added to a trusted keyring, this patch set further restricts the certificates to those signed by a particular key or builtin keys on the system keyring.
This patch defines a new kernel parameter 'keys_ownerid={id: | builtin}' to use specific key or any builtin key.
Changes to v1: * key id matching code from asymmetric_type.c is reused in the patch
Thanks, Dmitry
