KEYS: validate certificate trust only with selected key
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 further restricts the certificates to those signed by a
particular key on the system keyring.
This patch defines a new kernel parameter 'ca_keys' to identify the
specific key which must be used for trust validation of certificates.
Simplified Mimi's "KEYS: define an owner trusted keyring" patch.
Changelog:
- support for builtin x509 public keys only
- export "asymmetric_keyid_match"
- remove ifndefs MODULE
- rename kernel boot parameter from keys_ownerid to ca_keys
