A recent review of related changes noted that we should split the creation (or generation) of the master key into the qemuProcessPrepareDomain and leave the writing of the master key for qemuProcessPrepareHost. Made the adjustment and modified some comments to functions that have changed calling parameters, but didn't change the intro doc.

Commit id '40d8e2ba3' added the function to qemuProcessStart because in order to set up some secrets in the future we will need the master key. However, since the previous patch split the master key creation into two parts (create just the key and create the file), we can now call qemuDomainSecretPrepare from qemuProcessPrepareDomain since the file is not necessary.

Add the data structure and infrastructure to support an initialization vector (IV) secrets. The IV secret generation will need to have access to the domain private master key, so let's make sure the prepare disk and hostdev functions can accept that now. Anywhere that needs to make a decision over which secret type to use in order to fill in or use the IV secret has a switch added.

New APIs: qemuDomainGetIVKeyAlias: Generate/return the secret object alias for an initialization vector (IV) secret info type. This will be saved in the secret info block. This will be called from qemuDomainSecretIVSetup. qemuDomainSecretHaveEncrypt: Boolean function to determine whether the underly encryption API is available. This function will utilize a similar mechanism as the 'gnutls_rnd' did in configure.ac. For this patch it just returns false. This API is separate from the following one so that it's possible for the caller to determine whether or not it's possible to create an IV secret before trying and if not available fall back to the plain secret mechanism. qemuDomainSecretIVSetup: (private) This API handles the details of the generation of the IV 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. They can be passed either directly or within a file. This implementation chooses to pass directly rather than a file. qemuDomainSecretSetup: (private) Shim to call either the IV or Plain Setup functions based upon whether IV secrets are possible (we have the encryption API) or not. For this patch, the call will still be to set up the Plain since qemuDomainSecretHaveEncrypt hasn't been enabled yet. Use the qemuDomainSecretSetup in qemuDomainSecretDiskPrepare and qemuDomainSecretHostdevPrepare to add the secret rather than assuming plain.

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 iSCSI and RBD volumes instead of passing plaintext or base64 encoded secrets on the command line. Adjust the qemuDomainSecretHaveEncrypt API in order to check for the HAVE_GNUTLS_CIPHER_ENCRYPT being set as the primary decision point to whether an IV secret can be attempted and fall back to plain secret if the API is not available. The goal is to make IV secrets the default and have no user interaction required in order to allow using the IV mechanism. If the mechanism is not available, then fall back to the current mechanism. New API's: qemuBuildSecretInfoProps: (private) Generate/return a JSON properties object for the IV 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. qemuBuildSecretIVCommandLine (private) Generate and add to the command line the -object secret for the IV secret. This will be required for the subsequent iSCSI or RBD reference to the object. qemuBuildiSCSICommandLine: (private) Required for iSCSI since qemu only processes the "user=" and "password-secret=" options for an "-iscsi" entry. At some point in a future release, qemu may support those options on the -drive command line for iscsi devices. The one caveat to this code is rather than provide an 'id=' field for the -iscsi command, use the "initiator-name=" argument since it doesn't have the same restrictions regarding characters. The initiator-name is described as taking an IQN, which is the path argument. qemuBuildDiskSecinfoCommandLine qemuBuildHostdevSecretCommandLine These API's will handle adding the IV secret object and if necessary the '-iscsi' command line option. For an RBD disk, only the IV secret object will be required. Command Building: Adjust the qemuBuild{General|RBD}SecinfoURI API's in order to generate the specific command options for an IV secret, such as: For iSCSI: -object secret,id=$alias,keyid=$masterKey,data=$base64encodedencrypted, format=base64 -iscsi -initiator-name=$iqn,user=user,password-secret=$alias -drive file=iscsi://example.com/$iqn,... For RBD: -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 for both 'id=' value is the secret object alias generated by concatenating the disk/hostdev alias and "-ivKey0". The 'keyid= $masterKey' is the master key shared with qemu, and the -drive syntax will reference that alias as the 'password-secret'. For the iSCSI object 'user=' replaces the URI generated 'user:secret@' prepended to the iSCSI 'host' name (example.com). For the RBD -drive syntax, the 'id=myname' is kept to define the username, while the 'key=$base64 encoded secret' is removed. While according to the syntax described for qemu commits 'b189346eb' (iSCSI) and '60390a21' (RBD) 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. Tests: Add mock's for virRandomBytes and gnutls_rnd in order to return a constant stream of '0xff' in the bytes for a non random key in order to generate "constant" values for the secrets so that the tests can use those results to compare results. Hotplug: Since the hotplug code doesn't add command line arguments, passing the encoded/plaintext secrets directly to the monitor will suffice. Besides, it's passing the IV secret via '-iscsi' won't be possible. Perhaps when the -drive command is modified to accept not only the initiator-name, but -user and -password-secret arguments, then the IV code can be utilized for hotplug secrets.
