https://bugzilla.redhat.com/show_bug.cgi?id=1182074 If they're available and we need to pass secrets to qemu, then use the qemu domain secret object in order to pass the secrets for RBD volumes instead of passing the base64 encoded secret on the command line. The goal is to make AES secrets the default and have no user interaction required in order to allow using the AES mechanism. If the mechanism is not available, then fall back to the current plain mechanism using a base64 encoded secret. New APIs: qemu_domain.c: qemuDomainGetSecretAESAlias: Generate/return the secret object alias for an AES Secret Info type. This will be called from qemuDomainSecretAESSetup. qemuDomainSecretAESSetup: (private) This API handles the details of the generation of the AES secret and saves the pieces that need to be passed to qemu in order for the secret to be decrypted. The encrypted secret based upon the domain master key, an initialization vector (16 byte random value), and the stored secret. Finally, the requirement from qemu is the IV and encrypted secret are to be base64 encoded. qemu_command.c: qemuBuildSecretInfoProps: (private) Generate/return a JSON properties object for the AES secret to be used by both the command building and eventually the hotplug code in order to add the secret object. Code was designed so that in the future perhaps hotplug could use it if it made sense. qemuBuildObjectSecretCommandLine (private) Generate and add to the command line the -object secret for the secret. This will be required for the subsequent RBD reference to the object. qemuBuildDiskSecinfoCommandLine (private) Handle adding the AES secret object. Adjustments: qemu_domain.c: The qemuDomainSecretSetup was altered to call either the AES or Plain Setup functions based upon whether AES secrets are possible (we have the encryption API) or not, we have secrets, and of course if the protocol source is RBD. qemu_command.c: Adjust the qemuBuildRBDSecinfoURI API's in order to generate the specific command options for an AES secret, such as: -object secret,id=$alias,keyid=$masterKey,data=$base64encodedencrypted, format=base64 -drive file=rbd:pool/image:id=myname:auth_supported=cephx\;none:\ mon_host=mon1.example.org\:6321,password-secret=$alias,... where the 'id=' value is the secret object alias generated by concatenating the disk alias and "-aesKey0". The 'keyid= $masterKey' is the master key shared with qemu, and the -drive syntax will reference that alias as the 'password-secret'. For the -drive syntax, the 'id=myname' is kept to define the username, while the 'key=$base64 encoded secret' is removed. While according to the syntax described for qemu commit '60390a21' or as seen in the email archive: https://lists.gnu.org/archive/html/qemu-devel/2016-01/msg04083.html it is possible to pass a plaintext password via a file, the qemu commit 'ac1d8878' describes the more feature rich 'keyid=' option based upon the shared masterKey. Add tests for checking/comparing output. NB: For hotplug, since the hotplug code doesn't add command line arguments, passing the encoded secret directly to the monitor will suffice.
