Right now, _filter_img_create just filters out everything that looks
format-dependent, and applies some filename filters. That means that we
have to add another filter line every time some format gets a new
creation option. This can be avoided by instead discarding everything
and just keeping what we know is format-independent (format, size,
backing file, encryption information[1], preallocation) or just
interesting to have in the reference output (external data file path).
Furthermore, we probably want to sort these options. Format drivers are
not required to define them in any specific order, so the output is
effectively random (although this has never bothered us until now). We
need a specific order for our reference outputs, though. Unfortunately,
just using a plain "sort" would change a lot of existing reference
outputs, so we have to pre-filter the option keys to keep our existing
order (fmt, size, backing*, data, encryption info, preallocation).
Finally, this makes it difficult for _filter_img_create to automagically
work for QMP output. Thus, this patch adds a separate
_filter_img_create_for_qmp function that echos every line verbatim that
does not start with "Formatting", and pipes those "Formatting" lines to
_filter_img_create.
[1] Actually, the only thing that is really important is whether
encryption is enabled or not. A patch by Maxim thus removes all
other "encrypt.*" options from the output:
https://lists.nongnu.org/archive/html/qemu-block/2020-06/msg00339.html
But that patch needs to come later so we can get away with changing
as few reference outputs in this patch here as possible.

'force' option will be used for some unsafe amend operations.
This includes things like erasing last keyslot in luks based formats
(which destroys the data, unless the master key is backed up
by external means), but that _might_ be desired result.

From: Maxim Levitsky <mlevitsk@redhat.com>
Some options are only useful for creation
(or hard to be amended, like cluster size for qcow2), while some other
options are only useful for amend, like upcoming keyslot management
options for luks
Since currently only qcow2 supports amend, move all its options
to a common macro and then include it in each action option list.
In future it might be useful to remove some options which are
not supported anyway from amend list, which currently
cause an error message if amended.

To: qemu-block; +Cc: Kevin Wolf, Peter Maydell, qemu-devel, Max Reitz
From: Maxim Levitsky <mlevitsk@redhat.com>
Some qcow2 create options can't be used for amend.
Remove them from the qcow2 create options and add generic logic to detect
such options in qemu-img

To: qemu-block; +Cc: Kevin Wolf, Peter Maydell, qemu-devel, Max Reitz
From: Maxim Levitsky <mlevitsk@redhat.com>
rename the write_func to create_write_func, and init_func to create_init_func.
This is preparation for other write_func that will be used to update the encryption keys.
No functional changes

To: qemu-block; +Cc: Kevin Wolf, Peter Maydell, qemu-devel, Max Reitz
From: Maxim Levitsky <mlevitsk@redhat.com>
This implements the encryption key management using the generic code in
qcrypto layer and exposes it to the user via qemu-img
This code adds another 'write_func' because the initialization
write_func works directly on the underlying file, and amend
works on instance of luks device.
This commit also adds a 'hack/workaround' I and Kevin Wolf (thanks)
made to make the driver both support write sharing (to avoid breaking the users),
and be safe against concurrent metadata update (the keyslots)
Eventually the write sharing for luks driver will be deprecated
and removed together with this hack.
The hack is that we ask (as a format driver) for BLK_PERM_CONSISTENT_READ
and then when we want to update the keys, we unshare that permission.
So if someone else has the image open, even readonly, encryption
key update will fail gracefully.
Also thanks to Daniel Berrange for the idea of
unsharing read, rather that write permission which allows
to avoid cases when the other user had opened the image read-only.

To: qemu-block; +Cc: Kevin Wolf, Peter Maydell, qemu-devel, Max Reitz
From: Maxim Levitsky <mlevitsk@redhat.com>
blockdev-amend will be used similiar to blockdev-create
to allow on the fly changes of the structure of the format based block devices.
Current plan is to first support encryption keyslot management for luks
based formats (raw and embedded in qcow2)

Commit 96927c744 replaced qdev_init_nofail() call by
isa_realize_and_unref() which has a different error
message. Update the test output accordingly.

820c6bee534ec3b added testing of qcow2.py into 291, and it breaks 291
with external data file. Actually, 291 is bad place for qcow2.py
testing, better add a separate test.
For now, drop qcow2.py testing from 291 to fix the regression.
Fixes: 820c6bee534ec3b

Hi; I see various iotest failures, different things on
PPC64 Linux, OpenBSD and FreeBSD, and on an AArch32 build
that happens to not have optional crypto libs installed.
On PPC64 Linux, lots of iotests fail like this:

Looks like you're trying to use a readarray option that doesn't
exist (maybe only exists in newer shells?)
iotests failures on aarch32 which happens to not have some
optional crypto lib dependency installed I guess; these
iotests ought to be made to skip if the functionality they're
testing isn't compiled into this QEMU:

OK. Sorry. None of this looks easily fixable, so I suppose I’ll have
to drop everything but the last two patches for now.

Yes, I am. Well, that’s a real shame. :/
I wasn’t aware that readarray’s -d option was only introduced at some
later point. Looks like that happened in 4.4, which was only released
2016. So that’s probably too new indeed.

Well that’s nice. Maxim, I think we’ll need a for (()) loop then (like
e.g. tests/qemu-iotests/common.pattern:25 does it).

I assume the SIGKILL occurred because 295 somewhere waits on some QMP
event that never happens (probably because the encryption is again not
supported), so the iotest kills it on timeout.
(Maxim, I think that we’ll need something similar to what we need in 293
to skip the test if there’s no crypto library.)

It’s assuming that \x0 produces a NUL character. It’s a shame it
doesn’t, but I suppose it doesn’t even really matter without readarray
supporting -d.
