eCryptfs: verify authentication tokens before their use
Authentication tokens content may change if another requestor calls the update() method of the corresponding key. The new function ecryptfs_verify_auth_tok_from_key() retrieves the authentication token from the provided key and verifies if it is still valid before being used to encrypt or decrypt an eCryptfs file.
