86ce1f6e2b qemu-img: add the 'dd' subcommand
This patch adds a basic dd subcommand analogous to dd(1) to qemu-img.

For the start, this implements the bs, if, of and count options and requires
both if and of to be specified (no stdin/stdout if not specified) and doesn't
support tty, pipes, etc.

The image format must be specified with -O for the output if the raw format
is not the intended one.

Two tests are added to test qemu-img dd.

4e9b25fb05 block: enable testing of LUKS driver with block I/O tests
This adds support for testing the LUKS driver with the block
I/O test framework.

   cd tests/qemu-io-tests
   ./check -luks

A handful of test cases are modified to work with luks

 - 004 - whitelist luks format
 - 012 - use TEST_IMG_FILE instead of TEST_IMG for file ops
 - 048 - use TEST_IMG_FILE instead of TEST_IMG for file ops.
         don't assume extended image contents is all zeros,
         explicitly initialize with zeros
         Make file size smaller to avoid having to decrypt
         1 GB of data.
 - 052 - don't assume initial image contents is all zeros,
         explicitly initialize with zeros
 - 100 - don't assume initial image contents is all zeros,
         explicitly initialize with zeros

With this patch applied, the results are as follows:

The reasons for the failed tests are:

 - 033 - needs adapting to use image opts syntax with blkdebug
         and test image in order to correctly set align property
 - 120 - needs adapting to use correct -drive syntax for luks
 - 140 - needs adapting to use correct -drive syntax for luks
 - 145 - needs adapting to use correct -drive syntax for luks

The vast majority of skipped tests are exercising code that is
qcow2 specific, though a couple could probably be usefully
enabled for luks too.

b7e875b2f9 block: add support for encryption secrets in block I/O tests
The LUKS block driver tests will require the ability to specify
encryption secrets with block devices. This requires using the
--object argument to qemu-img/qemu-io to create a 'secret'
object.

When the IMGKEYSECRET env variable is set, it provides the
password to be associated with a secret called 'keysec0'

The _qemu_img_wrapper function isn't modified as that needs
to cope with differing syntax for subcommands, so can't be
made to use the image opts syntax unconditionally.

076003f526 block: add support for --image-opts in block I/O tests
Currently all block tests use the traditional syntax for images
just specifying a filename. To support the LUKS driver without
resorting to JSON, the tests need to be able to use the new
--image-opts argument to qemu-img and qemu-io.

This introduces a new env variable IMGOPTSSYNTAX. If this is
set to 'true', then qemu-img/qemu-io should use --image-opts.

e6c17669eb qemu-iotests: fix -valgrind option for check
Commit 934659c switched the iotests to run qemu-io from a bash subshell,
in order to catch segfaults.  This method is incompatible with the
current valgrind_qemu_io() bash function.

Move the valgrind usage into the exec subshell in _qemu_io_wrapper(),
while making sure the original return value is passed back to the
caller.

Update test output for tests 039, 061, and 137 as it looks for the
specific subshell command when the process is terminated.

f6c8c2e055 qemu-iotests: fix cleanup of background processes
Commit 934659c switched the iotests to run qemu and qemu-nbd from a bash
subshell, in order to catch segfaults.  Unfortunately, this means the
process PID cannot be captured via '$!'. We stopped killing qemu and
qemu-nbd processes, leaving a lot of orphaned, running qemu processes
after executing iotests.

Since the process is using exec in the subshell, the PID is the
same as the subshell PID.

Track these PIDs for cleanup using pidfiles in the $TEST_DIR. Only
track the qemu PID, however, if requested - not all usage requires
killing the process.

934659c460 iotests: Do not suppress segfaults in bash tests
Currently, if a qemu/qemu-io/qemu-img/qemu-nbd invocation receives a
segmentation fault, that message is invisible in most cases since the
output is generally filtered and bash suppresses the segmentation fault
notice for any but the last element of a pipe.

Most of the time, the test will then fail anyway because of missing
output, but not necessarily (as happened with test 82 recently).

Fix this by making the corresponding environment variables point to
wrapper functions which execute the respective command in a subshell.

Giving options to qemu/qemu-io/qemu-img and path names with spaces were
broken for the Python tests; this patch "accidentally" fixes that.

e8f8624d3b iotests: Allow out-of-tree run
As out-of-tree builds are preferred for qemu, running the qemu-iotests
in that out-of-tree build should be supported as well. To do so, a
symbolic link has to be created pointing to the check script in the
source directory. That script will check whether it has been run through
a symlink, and if so, will assume it is run in the build tree. All
output and temporary operations performed by iotests are then redirected
here and, unless specified otherwise by the user, QEMU_PROG etc. will be
set to paths appropriate for the build tree.

Also, drop making every test case executable if it is not yet, as this
would modify the source tree which is not desired for out-of-tree runs
and should be fixed in the repository anyway.

This adds the VHDX format to the qemu-iotests format, and adds

was created with Hyper-V under Windwos Server 2012.

The image file is a 1GB dynamic image, with 32MB blocks.

The pattern 0xa5 exists from 0MB-33MB (past a block size boundary)

The pattern 0x96 exists from 33MB-66MB (past another block boundary,
and leaving a partial blank block)

From 66MB-1024MB, all reads should return 0.

Although 1GB dynamic image with 66MB of data, the bzip2'ed image
file size is only 874 bytes.

This also adds in the IMGFMT_GENERIC flag, so r/o images can be

4c2e946500 qemu-iotests: Discard specific info in _img_info
In _img_info, filter out additional information specific to the image
format provided by qemu-img info, since tests designed for multiple
image formats would produce different outputs for every image format
otherwise.

In a human-readable dump, that new information will always be last for
each "image information block" (multiple blocks are emitted when
inspecting the backing file chain). Every block is separated by an empty
line. Therefore, in this case, everything starting with the line "Format
specific information:" up to that empty line (or EOF, if it is the last
block) has to be stripped.

The JSON dump will always emit pretty JSON data. Therefore, the opening
and closing braces of every object will be on lines which are indented
by exactly the same amount, and all lines in between will have more
indentation. Thus, in this case, everything starting with a line
matching the regular expression /^ *"format-specific": {/ until /^ *},?/
has to be stripped, where the number of spaces at the beginning of the
respective lines is equal.

85edbd375b qemu-iotests: Add basic ability to use binary sample images
For image formats that are not "QEMU native", but supported for
compatibility, it is useful to verify that an image created with
the 'gold standard' native tool can be read / written to successfully
by QEMU.

In addition to testing non-native images, this could also be useful to
test against image files created by older versions of QEMU.

This provides a directory to store small sample images, for use by
scripts in tests/qemu-iotests.

Image files should be compressed with bzip2.

To use a sample image from a bash script, the _use_sample_img function
will copy and decompress the image into $TEST_DIR, and set $TEST_IMG to
be the decompressed sample image copy.  To cleanup, call
_cleanup_test_img as normal.

2c78857bf6 qemu-iotests: Adjustments due to error propagation
When opening/creating images, propagating errors instead of immediately
emitting them on occurrence results in errors generally being printed on
a single line rather than being split up into multiple ones. This in
turn requires adjustments to some test results.

Also, test 060 used a sed to filter out the test image directory and
format by removing everything from the affected line after a certain
keyword; this now also removes the error message itself, which can be
fixed by using _filter_testdir and _filter_imgfmt.

Finally, _make_test_img in common.rc did not filter out the test image
directory etc. from stderr. This has been fixed through a redirection of
stderr to stdout (which is already done in _check_test_img and
_img_info).

c6bb9ad198 qemu-img: find the image end offset during check
This patch adds the support for reporting the image end offset (in
bytes). This is particularly useful after a conversion (or a rebase)
where the destination is a block device in order to find the first
unused byte at the end of the image.

a9660664fd tests: allow qemu-iotests to be run against nbd backend
To do this, we start a qemu-nbd process at _make_test_img and kill
it in _cleanup_test_img. $TEST_IMG is changed to point at the TCP
server. We also remove the checks for existence of binaries from
common.config - they're duplicated in common, and we can make the
qemu-nbd check conditional on $IMGPROTO being "nbd" if we do it there.

b0869a46b2 qemu-iotests: Be more flexible with image creation options
qemu-iotests already filters out image creation options that may be
present or not in order to get the same output in both cases. However,
often it only considers the default value of the option. Cover all valid
values instead so that ./check -o name=value can be used successfull for
all of them.

Hide the default lazy_refcounts=off output from qemu-img like we do with
other image creation options.  This ensures that existing golden outputs
continue to pass despite the new option that has been added.

Note that this patch applies before the one that actually introduces the
lazy_refcounts=on|off option.  This ensures git-bisect(1) continues to
work.

GNU getopt also allows options at the end, but POSIX getopt
doesn't. Try "export POSIXLY_CORRECT=y" to get the POSIX

bfe8524862 qemu-iotests: Update filter for default cluster size
Until recently, qemu-img create displayed cluster_size=0 for the default
cluster size. It is changed to display the real cluster size now, which results
in the cluster size not being filtered out any more.

If the cluster size is specified explicitly in CLUSTER_SIZE, keep the output,
and if using the default, filter it out. This mostly restores the old behaviour
of the test cases; test 015 must be fixed to use CLUSTER_SIZE instead of using
extra_img_options for it.
