KEYS: prevent keys from being removed from specified keyrings Userspace should not be allowed to remove keys from certain keyrings (eg. blacklist), though the keys themselves can expire. This patch defines a new key flag named KEY_FLAG_KEEP to prevent userspace from being able to unlink, revoke, invalidate or timed out a key on a keyring. When this flag is set on the keyring, all keys subsequently added are flagged. In addition, when this flag is set, the keyring itself can not be cleared.
