Subject: integrity: prevent loading untrusted certificates on the IMA trusted keyring

From: Dmitry Kasatkin <[email protected]>

commit 72e1eed8abb11c79749266d433c817ce36732893 upstream.

If IMA_LOAD_X509 is enabled, either directly or indirectly via IMA_APPRAISE_SIGNED_INIT, certificates are loaded onto the IMA trusted keyring by the kernel via key_create_or_update(). When the KEY_ALLOC_TRUSTED flag is provided, certificates are loaded without first verifying the certificate is properly signed by a trusted key on the system keyring. This patch removes the KEY_ALLOC_TRUSTED flag.
