Recently meson started complaining that TAP test reports don't include
the TAP protocol version. While this warning is bogus and has since been
removed from Meson, it looks like good practice to include this header
going forward. The GLib library test harness has started unconditionally
printing the version, so this brings the I/O tests into line.

When asking 'check' to list individual tests by invoking it in dry run
mode, it prints the paths to the tests relative to the base of the
I/O test directory.
When asking 'check' to run an individual test, however, it mandates that
only the unqualified test name is given, without any path prefix. This
inconsistency makes it harder to ask for a list of tests and then invoke
each one.
Thus the test listing code is change to flatten the test names, by
printing only the base name, which can be directly invoked.

The 'check' script can be invoked in "dry run" mode, in which case it
merely does test discovery and prints out all their names. Despite only
doing test discovery it still validates that the various QEMU binaries
can be found. This makes it impossible todo test discovery prior to
building QEMU. This is a desirable feature to support, because it will
let meson discover tests.
Fortunately the code in the TestEnv constructor is ordered in a way
that makes this fairly trivial to achieve. We can just short circuit
the constructor after the basic directory paths have been set.

The 'check' script has some rather dubious logic whereby it assumes
that if invoked as a symlink, then it is running from a separate
source tree and build tree, otherwise it assumes the current working
directory is a combined source and build tree.
This doesn't work if you want to invoke the 'check' script using
its full source tree path while still using a split source and build
tree layout. This would be a typical situation with meson if you ask
it to find the 'check' script path using files('check').
Rather than trying to make the logic more magical, add support for
explicitly passing the dirs using --source-dir and --build-dir. If
either is omitted the current logic is maintained.

Try writing zeroes to a FUSE export while allowing the area to be
unmapped; block/file-posix.c generally implements writing zeroes with
BDRV_REQ_MAY_UNMAP ('write -zu') by calling fallocate(PUNCH_HOLE). This
used to lead to a blk_pdiscard() in the FUSE export, which may or may
not lead to the area being zeroed. HEAD^ fixed this to use
blk_pwrite_zeroes() instead (again with BDRV_REQ_MAY_UNMAP), so verify
that running `qemu-io 'write -zu'` on a FUSE exports always results in

Currently, when querying a qcow2 image, qemu-img info reports something
like this:
image: test.qcow2
file format: qcow2
virtual size: 64 MiB (67108864 bytes)
disk size: 196 KiB
cluster_size: 65536
Format specific information:
compat: 1.1
compression type: zlib
lazy refcounts: false
refcount bits: 16
corrupt: false
extended l2: false
Child node '/file':
image: test.qcow2
file format: file
virtual size: 192 KiB (197120 bytes)
disk size: 196 KiB
Format specific information:
extent size hint: 1048576
Notably, the way the keys are named is specific for image files: The
filename is shown under "image", the BDS driver under "file format", and
the BDS length under "virtual size". This does not make much sense for
nodes that are not actually supposed to be guest images, like the /file
child node shown above.
Give bdrv_node_info_dump() a @protocol parameter that gives a hint that
the respective node is probably just used for data storage and does not
necessarily present the data for a VM guest disk. This renames the keys
so that with this patch, the output becomes:
image: test.qcow2
[...]
Child node '/file':
filename: test.qcow2
protocol type: file
file length: 192 KiB (197120 bytes)
disk size: 196 KiB
Format specific information:
extent size hint: 1048576
(Perhaps we should also rename "Format specific information", but I
could not come up with anything better that will not become problematic
if we guess wrong with the protocol "heuristic".)
This change affects iotest 302, which has protocol node information in

For every node in the backing chain, collect its BlockGraphInfo struct
using bdrv_query_block_graph_info(). Print all nodes' information,
indenting child nodes and labelling them with a path constructed from
the child names leading to the node from the root (e.g. /file/file).
Note that we open each image with BDRV_O_NO_BACKING, so its backing
child is omitted from this graph, and thus presented in the previous
manner: By simply concatenating all images' information, separated with
blank lines.
This affects two iotests:
- 065: Here we try to get the format node's format specific information.
The pre-patch code does so by taking all lines from "Format specific
information:" until an empty line. This format specific information
is no longer followed by an empty line, though, but by child node
information, so limit the range by "Child node '/file':".
- 302: Calls qemu_img() for qemu-img info directly, which does not
filter the output, so the child node information ends up in the
output.

At present there are two callers of get_tmp_filename() and they are
inconsistent.
One does:
/* TODO: extra byte is a hack to ensure MAX_PATH space on Windows. */
char *tmp_filename = g_malloc0(PATH_MAX + 1);
...
ret = get_tmp_filename(tmp_filename, PATH_MAX + 1);
while the other does:
s->qcow_filename = g_malloc(PATH_MAX);
ret = get_tmp_filename(s->qcow_filename, PATH_MAX);
As we can see different 'size' arguments are passed. There are also
platform specific implementations inside the function, and the use
of snprintf is really undesirable.
The function name is also misleading. It creates a temporary file,
not just a filename.
Refactor this routine by changing its name and signature to:
char *create_tmp_file(Error **errp)
and use g_get_tmp_dir() / g_mkstemp() for a consistent implementation.
While we are here, add some comments to mention that /var/tmp is
preferred over /tmp on non-win32 hosts.

Commit 5f76a7aac1 is looking harmless from
the first glance, but it has changed things a lot. 'libvirt' uses it to
detect that it should follow new initialization way and this changes
things considerably. With this procedure followed, blockdev_init() is
not called anymore and thus block_acct_setup() helper is not called.
This means in particular that defaults for block accounting statistics
are changed and account_invalid/account_failed are actually initialized
as false instead of true originally.
This commit changes things to match original world. There are the following
constraints:
* new default value in block_acct_init() is set to true
* block_acct_setup() inside blockdev_init() is called before
blkconf_apply_backend_options()
* thus newly created option in block device properties has precedence if
specified

According to the NBD spec, a server that advertises
NBD_FLAG_CAN_MULTI_CONN promises that multiple client connections will
not see any cache inconsistencies: when properly separated by a single
flush, actions performed by one client will be visible to another
client, regardless of which client did the flush.
We always satisfy these conditions in qemu - even when we support
multiple clients, ALL clients go through a single point of reference
into the block layer, with no local caching. The effect of one client
is instantly visible to the next client. Even if our backend were a
network device, we argue that any multi-path caching effects that
would cause inconsistencies in back-to-back actions not seeing the
effect of previous actions would be a bug in that backend, and not the
fault of caching in qemu. As such, it is safe to unconditionally
advertise CAN_MULTI_CONN for any qemu NBD server situation that
supports parallel clients.
Note, however, that we don't want to advertise CAN_MULTI_CONN when we
know that a second client cannot connect (for historical reasons,
qemu-nbd defaults to a single connection while nbd-server-add and QMP
commands default to unlimited connections; but we already have
existing means to let either style of NBD server creation alter those
defaults). This is visible by no longer advertising MULTI_CONN for
'qemu-nbd -r' without -e, as in the iotest nbd-qemu-allocation.
The harder part of this patch is setting up an iotest to demonstrate
behavior of multiple NBD clients to a single server. It might be
possible with parallel qemu-io processes, but I found it easier to do
in python with the help of libnbd, and help from Nir and Vladimir in
writing the test.

When stdout is not a terminal, the buffer may not be flushed at each end
of line, so we should flush after each test is done. This is especially
apparent when run by check-block, in two ways:
First, when running make check-block -jX with X > 1, progress indication
was missing, even though testrunner.py does theoretically print each
test's status once it has been run, even in multi-processing mode.
Flushing after each test restores this progress indication.
Second, sometimes make check-block failed altogether, with an error
message that "too few tests [were] run". I presume that's because one
worker process in the job pool did not get to flush its stdout before
the main process exited, and so meson did not get to see that worker's
test results. In any case, by flushing at the end of run_test(), the
problem has disappeared for me.

FUSE exports' allow-other option defaults to "auto", which means that it
will try passing allow_other as a mount option, and fall back to not
using it when an error occurs. We make no effort to hide fusermount's
error message (because it would be difficult, and because users might
want to know about the fallback occurring), and so when allow_other does
not work (primarily when /etc/fuse.conf does not contain
user_allow_other), this error message will appear and break the
reference output.
We do not need allow_other here, though, so we can just pass
allow-other=off to fix that.

The commit jobs changes the backing file string stored in the image file
header belonging to the node above the commit’s top node to point to the
commit target (the base node). QEMU tries to be as accurate as
possible, and so in these test cases will include the filter that is
part of the block graph in that backing file string (by virtue of making
it a json:{} description of the post-commit subgraph). This makes
little sense outside of QEMU, though: Specifically, the throttle node in
that subgraph will dearly miss its supposedly associated throttle group
object.
When starting the commit job, we can specify a custom backing file
string to write into said image file, so let’s use that feature to write
the plain filename of the backing chain’s next actual image file there.
Explicitly provide the backing file so that opening the file outside of
QEMU (Where we will not have throttle groups) will succeed.

(Note: I'm leaving the logging suppression here unchanged. I had
suggested previously we use filters to scrub the PID out of the logging
information so it could just be diffed as part of the iotest output, but
that meant *always* scrubbing PID from logger output, which defeated the
point of even offering that information in the output to begin with.
Ultimately, I decided it's fine to just suppress the logger temporarily.)

One clear problem with how qcow2's refcount structure rebuild algorithm
used to be before "qcow2: Improve refcount structure rebuilding" was
that it is prone to failure for qcow2 images on block devices: There is
generally unused space after the actual image, and if that exceeds what
one refblock covers, the old algorithm would invariably write the
reftable past the block device's end, which cannot work. The new
algorithm does not have this problem.
Test it with three tests:
(1) Create an image with more empty space at the end than what one
refblock covers, see whether rebuilding the refcount structures
results in a change in the image file length. (It should not.)
(2) Leave precisely enough space somewhere at the beginning of the image
for the new reftable (and the refblock for that place), see whether
the new algorithm puts the reftable there. (It should.)
(3) Test the original problem: Create (something like) a block device
with a fixed size, then create a qcow2 image in there, write some
data, and then have qemu-img check rebuild the refcount structures.
Before HEAD^, the reftable would have been written past the image
file end, i.e. outside of what the block device provides, which
cannot work. HEAD^ should have fixed that.
("Something like a block device" means a loop device if we can use
one ("sudo -n losetup" works), or a FUSE block export with
growable=false otherwise.)

An iotest's 'paused' condition is fickle; it will be reported as true
whenever the job is drained, for example, or when it is in the process
of completing.
030 and 041 contain such checks, we should replace them by checking the
job status instead. (As was done for 129 in commit f9a6256b48
for the 'busy' condition.)
Additionally, when we want to test that a job is paused on error, we
might want to give it some time to actually switch to the paused state.
Do that by waiting on the corresponding JOB_STATUS_CHANGE event. (But
only if they are not already paused; the loops these places are in fetch
all VM events, so they may have already fetched that event from the

When the stream block job cuts out the nodes between top and base in
stream_prepare(), it does not drain the subtree manually; it fetches the
base node, and tries to insert it as the top node's backing node with
bdrv_set_backing_hd(). bdrv_set_backing_hd() however will drain, and so
the actual base node might change (because the base node is actually not
part of the stream job) before the old base node passed to
bdrv_set_backing_hd() is installed.
This has two implications:
First, the stream job does not keep a strong reference to the base node.
Therefore, if it is deleted in bdrv_set_backing_hd()'s drain (e.g.
because some other block job is drained to finish), we will get a
use-after-free. We should keep a strong reference to that node.
Second, even with such a strong reference, the problem remains that the
base node might change before bdrv_set_backing_hd() actually runs and as
a result the wrong base node is installed.
Both effects can be seen in 030's TestParallelOps.test_overlapping_5()
case, which has five nodes, and simultaneously streams from the middle
node to the top node, and commits the middle node down to the base node.
As it is, this will sometimes crash, namely when we encounter the
above-described use-after-free.
Taking a strong reference to the base node, we no longer get a crash,
but the resuling block graph is less than ideal: The expected result is
obviously that all middle nodes are cut out and the base node is the
immediate backing child of the top node. However, if stream_prepare()
takes a strong reference to its base node (the middle node), and then
the commit job finishes in bdrv_set_backing_hd(), supposedly dropping
that middle node, the stream job will just reinstall it again.
Therefore, we need to keep the whole subtree drained in
stream_prepare(), so that the graph modification it performs is
effectively atomic, i.e. that the base node it fetches is still the base
node when bdrv_set_backing_hd() sets it as the top node's backing node.
Verify this by asserting in said 030's test case that the base node is
always the top node's immediate backing child when both jobs are done.

237: "create" call output isn't actually logged. Use qemu_img_create()
instead, which checks the return code. Remove the empty lines from
the test output.
296: Two calls;
-create: Expected to succeed. Like other create calls, the output
isn't actually logged. Switch to a checked variant
(qemu_img_create) instead. The output for this test is
a mixture of both test styles, so actually replace the
blank line for readability.
-amend: This is expected to fail. Log the output.
After this patch, the only uses of qemu_img_pipe are internal to
iotests.py and will be removed in subsequent patches.

qemu_img_pipe calls blank their output when the command being run is a
'create' call and the command succeeds. Thus, the normative output for
this command in iotest 149 is to print a blank line. We can remove the
logging from this invocation and use a checked invocation, but we still
need to inspect the actual output to see if we want to retroactively
skip the test due to missing cipher support.

Replace calls to qemu_img_pipe('map', '--output=json', ...) with this
new function, which provides better diagnostic information on failure.
Note: The output for iotest 211 changes, because logging JSON after it

In the event that the return code is negative (the program crashed), or

re-write qemu_img() as a function that will by default raise a
VerboseProcessException (extended from CalledProcessException) on
non-zero return codes. This will produce a stack trace that will show
the command line arguments and return code from the failed process run.
Users that want something more flexible (there appears to be only one)
can use check=False and manage the return themselves. However, when the
return code is negative, the Exception will be raised no matter what.
This is done under the belief that there's no legitimate reason, even in
negative tests, to see a crash from qemu-img.

All isabus_dev_print() did was to print up to two IRQ numbers per
device. This is redundant if the IRQ numbers are present as QOM
properties (see e.g. the modified tests/qemu-iotests/172.out).
Now that the last devices relying on isabus_dev_print() had their IRQ
numbers QOM'ified, the contribution of this function ultimately became
redundant. Remove it.

When developing an I/O test it is typical to add some logic to the
test script, run it to view the output diff, and then apply the
output diff to the reference file. This can be drastically simplified
by letting the test runner update the reference file in place.
By setting 'QEMU_IOTESTS_REGEN=1', the test runner will report the
failure and show the diff, but at the same time update the reference
file. So next time the I/O test is run it will succeed.
Continuing to display the diff when updating the reference gives the
developer a chance to review what was changed.

Current scheme of image fleecing looks like this:
[guest] [NBD export]
| |
|root | root
v v
[copy-before-write] -----> [temp.qcow2]
| target |
|file |backing
v |
[active disk] <-------------+
- On guest writes copy-before-write filter copies old data from active
disk to temp.qcow2. So fleecing client (NBD export) when reads
changed regions from temp.qcow2 image and unchanged from active disk
through backing link.
This patch makes possible new image fleecing scheme:
[guest] [NBD export]
| |
| root | root
v file v
[copy-before-write]<------[snapshot-access]
| |
| file | target
v v
[active-disk] [temp.img]
- copy-before-write does CBW operations and also provides
snapshot-access API. The API may be accessed through
snapshot-access driver.
Benefits of new scheme:
1. Access control: if remote client try to read data that not covered
by original dirty bitmap used on copy-before-write open, client gets
-EACCES.
2. Discard support: if remote client do DISCARD, this additionally to
discarding data in temp.img informs block-copy process to not copy
these clusters. Next read from discarded area will return -EACCES.
This is significant thing: when fleecing user reads data that was
not yet copied to temp.img, we can avoid copying it on further guest
write.
3. Synchronisation between client reads and block-copy write is more
efficient. In old scheme we just rely on BDRV_REQ_SERIALISING flag
used for writes to temp.qcow2. New scheme is less blocking:
- fleecing reads are never blocked: if data region is untouched or
in-flight, we just read from active-disk, otherwise we read from
temp.img
- writes to temp.img are not blocked by fleecing reads
- still, guest writes of-course are blocked by in-flight fleecing
reads, that currently read from active-disk - it's the minimum
necessary blocking
4. Temporary image may be of any format, as we don't rely on backing
feature.
5. Permission relation are simplified. With old scheme we have to share
write permission on target child of copy-before-write, otherwise
backing link conflicts with copy-before-write file child write
permissions. With new scheme we don't have backing link, and
copy-before-write node may have unshared access to temporary node.
(Not realized in this commit, will be in future).
6. Having control on fleecing reads we'll be able to implement
alternative behavior on failed copy-before-write operations.
Currently we just break guest request (that's a historical behavior
of backup). But in some scenarios it's a bad behavior: better
is to drop the backup as failed but don't break guest request.
With new scheme we can simply unset some bits in a bitmap on CBW
failure and further fleecing reads will -EACCES, or something like
this. (Not implemented in this commit, will be in future)
Additional application for this is implementing timeout for CBW
operations.
Iotest 257 output is updated, as two more bitmaps now live in
copy-before-write filter.

Drop the use of OUTPUT_DIR (test/qemu-iotests under the build
directory), and instead write test output files (.out.bad, .notrun, and
.casenotrun) to TEST_DIR.
With this, the same test can be run concurrently without the separate
instances interfering, because they will need separate TEST_DIRs anyway.
Running the same test separately is useful when running the iotests with
various format/protocol combinations in parallel, or when you just want
to aggressively exercise a single test (e.g. when it fails only
sporadically).
Putting this output into TEST_DIR means that it will stick around for
inspection after the test run is done (though running the same test in
the same TEST_DIR will overwrite it, just as it used to be); but given
that TEST_DIR is a scratch directory, it should be clear that users can
delete all of its content at any point. (And if TEST_DIR is on tmpfs,
it will just disappear on shutdown.) Contrarily, alternative approaches
that would put these output files into OUTPUT_DIR with some prefix to
differentiate between separate test runs might easily lead to cluttering
OUTPUT_DIR.
(This change means OUTPUT_DIR is no longer written to by the iotests, so
we can drop its usage altogether.)

Instead of failing the iotests if GNU sed is not available (or skipping
them completely in the check-block.sh script), it would be better to
simply skip the bash-based tests that rely on GNU sed, so that the other
tests could still be run. Thus we now explicitely use "gsed" (either as
direct program or as a wrapper around "sed" if it's the GNU version)
in the spots that rely on the GNU sed behavior. Statements that use the
"-r" parameter of sed have been switched to use "-E" instead, since this
switch is supported by all sed versions on our supported build hosts
(most also support "-r", but macOS' sed only supports "-E"). With all
these changes in place, we then can also remove the sed checks from the
check-block.sh script, so that "make check-block" can now be run on
systems without GNU sed, too.

Test the following scenario:
1. Some block node (null-co) attached to a user (here: NBD server) that
performs I/O and keeps the node in an I/O thread
2. Repeatedly run blockdev-add/blockdev-del to add/remove an overlay
to/from that node
Each blockdev-add triggers bdrv_refresh_limits(), and because
blockdev-add runs in the main thread, it does not stop the I/O requests.
I/O can thus happen while the limits are refreshed, and when such a
request sees a temporarily invalid block limit (e.g. alignment is 0),
this may easily crash qemu (or the storage daemon in this case).
The block layer needs to ensure that I/O requests to a node are paused
while that node's BlockLimits are refreshed.

in its READY phase.
Add two test cases for this, where we respectively mirror or commit to
an external QSD instance, which provides a throttled block device. qemu
is supposed to cancel the job so that it can quit as soon as possible
instead of waiting for the job to complete (which it did before 6.2).

Move the permission API calls into driver-specific callbacks
that always run under BQL. In this case, bdrv_crypto_luks
needs to perform permission checks before and after
qcrypto_block_amend_options(). The problem is that the caller,
block_crypto_amend_options_generic_luks(), can also run in I/O
from .bdrv_co_amend(). This does not comply with Global State-I/O API split,
as permissions API must always run under BQL.
Firstly, introduce .bdrv_amend_pre_run() and .bdrv_amend_clean()
callbacks. These two callbacks are guaranteed to be invoked under
BQL, respectively before and after .bdrv_co_amend().
They take care of performing the permission checks
in the same way as they are currently done before and after
qcrypto_block_amend_options().
These callbacks are in preparation for next patch, where we
delete the original permission check. Right now they just add redundant
control.
Then, call .bdrv_amend_pre_run() before job_start in
qmp_x_blockdev_amend(), so that it will be run before the job coroutine
is created and stay in the main loop.
As a cleanup, use JobDriver's .clean() callback to call
.bdrv_amend_clean(), and run amend-specific cleanup callbacks under BQL.
After this patch, permission failures occur early in the blockdev-amend
job to update a LUKS volume's keys. iotest 296 must now expect them in
x-blockdev-amend's QMP reply instead of waiting for the actual job to
fail later.

Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
Put an NBD block device into an I/O thread, and then read data from it,
hoping that the NBD connection will yield during that read. When it
does, the coroutine must be reentered in the block device's I/O thread,
which will only happen if the NBD block driver attaches the connection's
QIOChannel to the new AioContext. It did not do that after 4ddb5d2fde
("block/nbd: drop connection_co") and prior to "block/nbd: Move s->ioc
on AioContext change", which would cause an assertion failure.
To improve our chances of yielding, the NBD server is throttled to
reading 64 kB/s, and the NBD client reads 128 kB, so it should yield at
some point.

Prior to "block/nbd: Delete reconnect delay timer when done" and
"block/nbd: Delete open timer when done", both of those timers would
remain scheduled even after successfully (re-)connecting to the server,
and they would not even be deleted when the BDS is deleted.
This test constructs exactly this situation:
(1) Configure an @open-timeout, so the open timer is armed, and
(2) Configure a @reconnect-delay and trigger a reconnect situation
(which succeeds immediately), so the reconnect delay timer is armed.
Then we immediately delete the BDS, and sleep for longer than the
@open-timeout and @reconnect-delay. Prior to said patches, this caused
one (or both) of the timer CBs to access already-freed data.
Accessing freed data may or may not crash, so this test can produce
false successes, but I do not know how to show the problem in a better
or more reliable way. If you run this test on "block/nbd: Assert there
are no timers when closed" and without the fix patches mentioned above,
you should reliably see an assertion failure.
(But all other tests that use the reconnect delay timer (264 and 277)
will fail in that configuration, too; as will nbd-reconnect-on-open,
which uses the open timer.)
Remove this test from the quick group because of the two second sleep
this patch introduces.
(I decided to put this test case into 281, because the main bug this
series addresses is in the interaction of the NBD block driver and I/O
threads, which is precisely the scope of 281. The test case for that
other bug will also be put into the test class added here.
Also, excuse the test class's name, I couldn't come up with anything
better. The "yield" part will make sense two patches from now.)

This is a rather simple class that allows creating a QSD instance
running in the background and stopping it when no longer needed.
The __del__ handler is a safety net for when something goes so wrong in
a test that e.g. the tearDown() method is not called (e.g. setUp()
launches the QSD, but then launching a VM fails). We do not want the
QSD to continue running after the test has failed, so __del__() will
take care to kill it.

This allows us to pack in some extra information about the failure,
which guarantees that if the caller did not *intentionally* cause a
failure (by capturing this Exception), some pretty good clues will be
printed at the bottom of the traceback information.
This will help make failures in the event of a non-negative return code
more obvious when they go unhandled; the current behavior in
_post_shutdown() is to print a warning message only in the event of
signal-based terminations (for negative return codes).
(Note: In Python, catching BaseException instead of Exception catches a
broader array of Exception events, including SystemExit and
KeyboardInterrupt. We do not want to "wrap" such exceptions as a
VMLaunchFailure, because that will 'downgrade' the exception from a
BaseException to a regular Exception. We do, however, want to perform
cleanup in either case, so catch on the broadest scope and
wrap-and-re-raise only in the more targeted scope.)

to filter output, which in turns filter a compression type. So it will
help us in future when we implement a possibility to use zstd
compression by default (with help of some runtime config file or maybe
build option). For now to test you should recompile qemu with a small
addition into block/qcow2.c before
"if (qcow2_opts->has_compression_type":
if (!qcow2_opts->has_compression_type && version >= 3) {

Adding support of IMGOPTS (like in bash tests) allows user to pass a
lot of different options. Still, some may require additional logic.
Now we want compression_type option, so add some smart logic around it:
ignore compression_type=zstd in IMGOPTS, if test want qcow2 in
compatibility mode. As well, ignore compression_type for non-qcow2
formats.
Note that we may instead add support only to qemu_img_create(), but
that works bad:
1. We'll have to update a lot of tests to use qemu_img_create instead
of qemu_img('create'). (still, we may want do it anyway, but no
reason to create a dependancy between task of supporting IMGOPTS and
updating a lot of tests)
2. Some tests use qemu_img_pipe('create', ..) - even more work on
updating
3. Even if we update all tests to go through qemu_img_create, we'll
need a way to avoid creating new tests using qemu_img*('create') -
add assertions.. That doesn't seem good.

This test assumes that mirror flushes the source when entering the READY
state, and that the format level will pass that flush on to the protocol
level (where we intercept it with blkdebug).
However, apparently that does not happen when using a VMDK image with
zeroed_grain=on, which actually is the default set by testenv.py. Right
now, Python tests ignore IMGOPTS, though, so this has no effect; but
Vladimir has a series that will change this, so we need to fix this test
before that series lands.
We can fix it by writing data to the source before we start the mirror
job; apparently that makes the (VMDK) format layer change its mind and
pass on the pre-READY flush to the protocol level, so the test passes
again. (I presume, without any data written, mirror just does a 64M
zero write on the target, which VMDK with zeroed_grain=on basically just
ignores.)
Without this, we do not get a flush, and so blkdebug only sees a single
flush at the end of the job instead of two, and therefore does not
inject an error, which makes the block job complete instead of raising
an error.

First, this permission never protected a node from being changed, as
generic child-replacing functions don't check it.
Second, it's a strange thing: it presents a permission of parent node
to change its child. But generally, children are replaced by different
mechanisms, like jobs or qmp commands, not by nodes.
Graph-mod permission is hard to understand. All other permissions
describe operations which done by parent node on its child: read,
write, resize. Graph modification operations are something completely
different.
The only place where BLK_PERM_GRAPH_MOD is used as "perm" (not shared
perm) is mirror_start_job, for s->target. Still modern code should use
bdrv_freeze_backing_chain() to protect from graph modification, if we
don't do it somewhere it may be considered as a bug. So, it's a bit
risky to drop GRAPH_MOD, and analyzing of possible loss of protection
is hard. But one day we should do it, let's do it now.

If i > tail, we do on aligned WRITE_ZERO (or skip if target is zeroed)
and again one unaligned WRITE, RMW happens.
Let's do better: don't fragment the whole-zero buffer and report it as
ZERO: in case of zeroed target we just do nothing and avoid RMW. If
target is not zeroes, one unaligned WRITE_ZERO should not be much worse
than one unaligned WRITE.

This demonstrates what happens when the block status changes in
sub-min_sparse granularity, but all of the parts are zeroed out. The
alignment logic in is_allocated_sectors() prevents that the target image
remains fully sparse as expected, but turns it into a data cluster of
explicit zeros.

With CAP_DAC_OVERRIDE (which e.g. root generally has), permission checks
will be bypassed when opening files.
308 in one instance tries to open a read-only file (FUSE export) with
qemu-io as read/write, and expects this to fail. However, when running
it as root, opening will succeed (thanks to CAP_DAC_OVERRIDE) and only
the actual write operation will fail.
Note this as "Case not run", but have the test pass in either case.

Test the following scenario:
- Simple stream block in two-layer backing chain (base and top)
- The job is drained via blk_drain(), then an error occurs while the job
settles the ongoing request
- And so the job completes while in blk_drain()
This was reported as a segfault, but is fixed by "block-backend: prevent
dangling BDS pointers across aio_poll()".

It's unused now (except for permission handling)[*]. The only reasonable
user of it was block-stream job, recently updated to use own blk. And
other block jobs prefer to use own source node related objects.
So, the arguments of dropping the field are:
- block jobs prefer not to use it
- block jobs usually has more then one node to operate on, and better
to operate symmetrically (for example has both source and target
blk's in specific block-job state structure)
*: BlockJob.blk is used to keep some permissions. We simply move
permissions to block-job child created in block_job_create() together
with blk.
In mirror, we just should not care anymore about restoring state of
blk. Most probably this code could be dropped long ago, after dropping
bs->job pointer. Now it finally goes away together with BlockJob.blk
itself.
iotest 141 output is updated, as "bdrv_has_blk(bs)" check in
qmp_blockdev_del() doesn't fail (we don't have blk now). Still, new
error message looks even better.
In iotest 283 we need to add a job id, otherwise "Invalid job ID"
happens now earlier than permission check (as permissions moved from
blk to block-job node).
