4.3-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dmitry Kasatkin <dmitry.kasatkin@xxxxxxxxx>
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.
