KEYS: verify a certificate is signed by a 'trusted' key
Only public keys, with certificates signed by an existing 'trusted' key on the system trusted keyring, should be added to a trusted keyring. This patch adds support for verifying a certificate's signature. This is derived from David Howells pkcs7_request_asymmetric_key() patch. Changelog v6: - on error free key - Dmitry - validate trust only for not already trusted keys - Dmitry - formatting cleanup Changelog: - define get_system_trusted_keyring() to fix kbuild issues Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com> Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Dmitry Kasatkin <dmitry.kasatkin@gmail.com>
