[Qemu-block] [PATCH v5 00/10] Make qemu-img/qemu-nbd/qemu-io CLI more flexible |
Date: |
Tue, 2 Feb 2016 12:57:34 +0000 |
This series of patches expands the syntax of the qemu-img,
qemu-nbd and qemu-io commands to make them more flexible.
v0: https://lists.gnu.org/archive/html/qemu-devel/2015-10/msg04365.html
v1: https://lists.gnu.org/archive/html/qemu-devel/2015-12/msg04014.html
v2: https://lists.gnu.org/archive/html/qemu-devel/2015-12/msg04354.html
v3: https://lists.gnu.org/archive/html/qemu-devel/2016-01/msg03381.html
v4: https://lists.gnu.org/archive/html/qemu-devel/2016-01/msg04984.html
First all three gain a --object parameter, which allows
instantiation of user creatable object types. The immediate
use case is to allow for creation of the 'secret' object
type to pass passwords for curl, iscsi and rbd drivers.
For qemu-nbd this will also be needed to create TLS
certificates for encryption support.
Then all three gain a '--image-opts' parameter which causes
the positional filenames to be interepreted as option strings
rather tha nplain filenames. This avoids the need to use the
JSON syntax, or to add custom CLI args for each block backend
option that exists. The immediate use case is to allow the
user to specify the ID of the 'secret' object they just created.
Finally, there are a few small cleanup patches
The first 4 patches in this series are a pre-requisite for
3 other series
- Support for TLS in NBD
- Support for secrets for passwd auth in curl, rbd, iscsi
(fixes a CVE issue in libvirt)
- Support for LUKS encryption passwords
Changed in v5:
- Move more common object creation code into qom/ (Kevin)
- Add missing @var{} syntax in CLI help definition (Kevin)
- Declare QemuOpts closer to time of use (Kevin)
- Directly reference registered opts instead of calling
qemu_find_opts (Kevin)
- Use consistent exit/return/goto pattern in qemu-img (Kevin)
- Remove special casing of 'file' in QemuOpts handling
for bdrv_open (Kevin)
- Split file file opening code out into separate method
(Kevin)
Changed in v4:
- Fix error reporting when object_create fails
Changed in v3:
- Rebase to resolve with conflicts against recently
merged code
- Remove use of errx()
Changed in v2:
- Share more common code in qom/object_interfaces.c to
avoid duplicating so much of 'object_create' in each
command
- Remove previously added '--source optstring' parameter
which replaced the positional filenames, in favour of
keeping the positional filenames but using a --image-opts
boolean arg to change their interpretation
- Added docs for --image-opts to qemu-img man page
- Use printf instead of echo -n in examples
- Line wrap help string based on user terminal width not
source code width
- Update qemu-nbd/qemu-io to use constants for options
- Update qemu-nbd to avoid overlapping option values
Daniel P. Berrange (10):
qom: add helpers for UserCreatable object types
qemu-img: add support for --object command line arg
qemu-nbd: add support for --object command line arg
qemu-io: add support for --object command line arg
qemu-io: allow specifying image as a set of options args
qemu-nbd: allow specifying image as a set of options args
qemu-img: allow specifying image as a set of options args
qemu-nbd: don't overlap long option values with short options
qemu-nbd: use no_argument/required_argument constants
qemu-io: use no_argument/required_argument constants
