This converts the qcow driver to make use of the QCryptoBlock
APIs for encrypting image content. This is only wired up to
permit use of the legacy QCow encryption format. Users who wish
to have the strong LUKS format should switch to qcow2 instead.
With this change it is now required to use the QCryptoSecret
object for providing passwords, instead of the current block
password APIs / interactive prompting.
$QEMU \
-object secret,id=sec0,file=/home/berrange/encrypted.pw \
-drive file=/home/berrange/encrypted.qcow,encrypt.format=aes,\
encrypt.key-secret=sec0
Though note that running QEMU system emulators with the AES
encryption is no longer supported, so while the above syntax
is valid, QEMU will refuse to actually run the VM in this
particular example.
Likewise when creating images with the legacy AES-CBC format
qemu-img create -f qcow \
--object secret,id=sec0,file=/home/berrange/encrypted.pw \
-o encrypt.format=aes,encrypt.key-secret=sec0 \
/home/berrange/encrypted.qcow 64M

In the process of getting rid of docs/qmp-commands.txt, we managed
to regress on some of the text that changed after the point where
the move was first branched and when the move actually occurred.
For example, commit 3282eca for blockdev-snapshot re-added the
extra "options" layer which had been cleaned up in commit 0153d2f.
This clears up all regressions identified over the range
02b351d..bd6092e:
https://lists.gnu.org/archive/html/qemu-devel/2017-05/msg05127.html
as well as a cleanup to x-blockdev-remove-medium to prefer

SocketAddress is a simple union, and simple unions are awkward: they
have their variant members wrapped in a "data" object on the wire, and
require additional indirections in C. I intend to limit its use to
existing external interfaces, and convert all internal interfaces to
SocketAddressFlat.
BlockdevOptionsNbd is an external interface using SocketAddress. We
already use SocketAddressFlat elsewhere in blockdev-add. Replace it
by SocketAddressFlat while we can (it's new in 2.9) for simplicity and
consistency. For example,
{ "execute": "blockdev-add",
"arguments": { "node-name": "foo", "driver": "nbd",
"server": { "type": "inet",
"data": { "host": "localhost",
"port": "12345" } } } }
becomes
{ "execute": "blockdev-add",
"arguments": { "node-name": "foo", "driver": "nbd",
"server": { "type": "inet",
"host": "localhost", "port": "12345" } } }
Since the internal interfaces still take SocketAddress, this requires
conversion function socket_address_crumple(). It'll go away when I
update the interfaces.
Unfortunately, SocketAddress is also visible in -drive since 2.8:
-drive if=none,driver=nbd,server.type=inet,server.data.host=127.0.0.1,server.data.port=12345
Nobody should be using it, as it's fairly new and has never been
documented, so adding still more compatibility gunk to keep it working
isn't worth the trouble. You now have to use
-drive if=none,driver=nbd,server.type=inet,server.host=127.0.0.1,server.port=12345

[mreitz: Change iotest 147 accordingly]
Because of this interface change, iotest 147 has to be adapted.
Unfortunately, we cannot just flatten all of the addresses because
nbd-server-start still takes a plain SocketAddress. Therefore, we need
both and this is most easily achieved by writing the SocketAddress into
the code and flattening it where necessary.

This reverts a part of commit 8a47e8e. We're having second thoughts
on the QAPI schema (and thus the external interface), and haven't
reached consensus, yet. Issues include:
* BlockdevOptionsRbd member @password-secret isn't actually a
password, it's a key generated by Ceph.
* We're not sure where member @password-secret belongs (see the
previous commit).
* How @password-secret interacts with settings from a configuration
file specified with @conf is undocumented.
Let's avoid painting ourselves into a corner now, and revert the
feature for 2.9.
Note that users can still configure an authentication key with a
configuration file. They probably do that anyway if they use Ceph
outside QEMU as well.

This reverts half of commit 0a55679. We're having second thoughts on
the QAPI schema (and thus the external interface), and haven't reached
consensus, yet. Issues include:
* The implementation uses deprecated rados_conf_set() key
"auth_supported". No biggie.
* The implementation makes -drive silently ignore invalid parameters
"auth" and "auth-supported.*.X" where X isn't "auth". Fixable (in
fact I'm going to fix similar bugs around parameter server), so
again no biggie.
* BlockdevOptionsRbd member @password-secret applies only to
authentication method cephx. Should it be a variant member of
RbdAuthMethod?
* BlockdevOptionsRbd member @user could apply to both methods cephx
and none, but I'm not sure it's actually used with none. If it
isn't, should it be a variant member of RbdAuthMethod?
* The client offers a *set* of authentication methods, not a list.
Should the methods be optional members of BlockdevOptionsRbd instead
of members of list @auth-supported? The latter begs the question
what multiple entries for the same method mean. Trivial question
now that RbdAuthMethod contains nothing but @type, but less so when
RbdAuthMethod acquires other members, such the ones discussed above.
* How BlockdevOptionsRbd member @auth-supported interacts with
settings from a configuration file specified with @conf is
undocumented. I suspect it's untested, too.
Let's avoid painting ourselves into a corner now, and revert the
feature for 2.9.
Note that users can still configure authentication methods with a
configuration file. They probably do that anyway if they use Ceph
outside QEMU as well.
Further note that this doesn't affect use of key "auth-supported" in
-drive file=rbd:...:key=value.
qemu_rbd_array_opts()'s parameter @type now must be RBD_MON_HOST,
which is silly. This will be cleaned up shortly.

We use InetSocketAddress in the QAPI schema. However, the code
doesn't use inet_connect_saddr(), but formats "host" and "port" into a
configuration string for rados_conf_set(). Thus, members "numeric",
"to", "ipv4" and "ipv6" are silently ignored. Not nice. Example:
-blockdev rbd,node-name=nn,pool=p,image=i,server.0.host=h0,server.0.port=12345,server.0.ipv4=off
Factor a suitable InetSocketAddressBase out of InetSocketAddress, and
use that. "numeric", "to", "ipv4" and "ipv6" are now rejected.

We traditionally mark optional members #optional in the doc comment.
Before commit 3313b61, this was entirely manual.
Commit 3313b61 added some automation because its qapi2texi.py relied
on #optional to determine whether a member is optional. This is no
longer the case since the previous commit: the only thing qapi2texi.py
still does with #optional is stripping it out. We still reject bogus
qapi-schema.json and six places for qga/qapi-schema.json.
Thus, you can't actually rely on #optional to see whether something is
optional. Yet we still make people add it manually. That's just
busy-work.
Drop the code to check, fix up and strip out #optional, along with all
instances of #optional. To keep it out, add code to reject it, to be
dropped again once the dust settles.
