[PATCH v1a 0/2] KEYS: validate key trust with owner and builtin keys only

[Dmitry Kasatkin <dmitry.kasatkin@gmail.com>]

This is a repost of the patchset cleanly on the top of linux-integrity
next-trusted-keys branch.

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:xxx | builtin}'
to use specific key or any builtin key.

Thanks,
Dmitry
