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.
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.
qemuDomainSecretInfoGetAlias:
Return a pointer to the alias to the specific secret info as
long as the secret object is supported (future patches may add
a new secret info type with a different pointer to return).
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. This function creates
the encrypted secret based upon the domain master key, an
initialization vector (16 byte random value), and the stored secret.
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 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 (file passing is shown below).
qemuBuildiSCSICommandLine: (private)
qemuBuildDiskiSCSICommandLine
qemuBuildHostdeviSCSICommandLine
These API's will handle adding the IV secret onto an '-iscsi'
command line option.
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.
Changes for qemuDomainSecret{Disk|Hostdev}Prepare:
If both the encryption API exists and the secret object exist, then
setup the IV secret (qemuDomainSecretIVSetup) as the default means
for the disk/hostdev to provide the secret to qemu. Prior to command
line generation and during hotplug, these prepare API's are called
allowing for code after the API to perform the right steps.
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=sec0,keyid=$masterKey,filename=/path/to/example.pw
or
-object secret,id=sec0,keyid=$masterKey,data=$base64encodedencrypted,
format=base64
-iscsi -initiator-name=$iqn,user=user,password-secret=sec0
-drive file=iscsi://example.com/$iqn/1,...
For RBD:
-object secret,id=secret0,keyid=$masterKey,file=/path/to/poolkey.b64,
format=base64
or
-object secret,id=secret0,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=secret0,...
where for both 'id=' value is the secret object alias, 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.
The goal is to make this 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.
