Unix sockets generally have a maximum path length. Depending on your
$TEST_DIR, it may be exceeded and then all tests that create and use
Unix sockets there may fail.
Circumvent this by adding a new scratch directory specifically for
Unix socket files. It defaults to a temporary directory (mktemp -d)
that is completely removed after the iotests are done.
(By default, mktemp -d creates a /tmp/tmp.XXXXXXXXXX directory, which
should be short enough for our use cases.)
Use mkdir -p to create the directory (because it seems right), and do
the same for $TEST_DIR (because there is no reason for that to be
created in any different way).

case_notrun() does not actually skip the current test case. It just
adds a "notrun" note and then returns to the caller, who manually has to
skip the test. Generally, skipping a test case is as simple as
returning from the current function, but not always: For example, this
model does not allow skipping tests already in the setUp() function.
Thus, add a QMPTestCase.case_skip() function that invokes case_notrun()
and then self.skipTest(). To make this work, we need to filter the
information on how many test cases were skipped from the unittest
output.

Without HEAD^, the following happens when you attempt a large write
request to a qcow2 file such that the number of bytes covered by all
clusters involved in a single allocation will exceed INT_MAX:
(A) handle_alloc_space() decides to fill the whole area with zeroes and
fails because bdrv_co_pwrite_zeroes() fails (the request is too
large).
(B) If handle_alloc_space() does not do anything, but merge_cow()
decides that the requests can be merged, it will create a too long
IOV that later cannot be written.
(C) Otherwise, all parts will be written separately, so those requests
will work.
In either B or C, though, qcow2_alloc_cluster_link_l2() will have an
overflow: We use an int (i) to iterate over nb_clusters, and then
calculate the L2 entry based on "i << s->cluster_bits" -- which will
overflow if the range covers more than INT_MAX bytes. This then leads
to image corruption because the L2 entry will be wrong (it will be
recognized as a compressed cluster).
Even if that were not the case, the .cow_end area would be empty
(because handle_alloc() will cap avail_bytes and nb_bytes at INT_MAX, so
their difference (which is the .cow_end size) will be 0).
So this test checks that on such large requests, the image will not be
corrupted. Unfortunately, we cannot check whether COW will be handled
correctly, because that data is discarded when it is written to null-co
(but we have to use null-co, because writing 2 GB of data in a test is
not quite reasonable).

For long test image paths, the order of the "Formatting" line and the

fact, the interaction between the prompt and the line may lead to the
"Formatting" to being greppable at all after "read"-ing it (if the
prompt injects an IFS character into the "Formatting" string).
So just wait until we get a prompt. At that point, the block job must
have been started, so "info block-jobs" will only return "No active

The BDRV_REQ_NO_FALLBACK flag means that an operation should only be
performed if it can be offloaded or otherwise performed efficiently.
However a misaligned write request requires a RMW so we should return
an error and let the caller decide how to proceed.
This hits an assertion since commit c8bb23cbdb if the required
alignment is larger than the cluster size:
qemu-img create -f qcow2 -o cluster_size=2k img.qcow2 4G
qemu-io -c "open -o driver=qcow2,file.align=4k blkdebug::img.qcow2" \
-c 'write 0 512'
qemu-io: block/io.c:1127: bdrv_driver_pwritev: Assertion `!(flags & BDRV_REQ_NO_FALLBACK)' failed.
Aborted
The reason is that when writing to an unallocated cluster we try to
skip the copy-on-write part and zeroize it using BDRV_REQ_NO_FALLBACK
instead, resulting in a write request that is too small (2KB cluster
size vs 4KB required alignment).

Drop write notifiers and use filter node instead.
= Changes =
1. Add filter-node-name argument for backup qmp api. We have to do it
in this commit, as 257 needs to be fixed.
2. There are no more write notifiers here, so is_write_notifier
parameter is dropped from block-copy paths.
3. To sync with in-flight requests at job finish we now have drained
removing of the filter, we don't need rw-lock.
4. Block-copy is now using BdrvChildren instead of BlockBackends
5. As backup-top owns these children, we also move block-copy state
into backup-top's ownership.
= Iotest changes =
56: op-blocker doesn't shoot now, as we set it on source, but then
check on filter, when trying to start second backup.
To keep the test we instead can catch another collision: both jobs will
get 'drive0' job-id, as job-id parameter is unspecified. To prevent
interleaving with file-posix locks (as they are dependent on config)
let's use another target for second backup.
Also, it's obvious now that we'd like to drop this op-blocker at all
and add a test-case for two backups from one node (to different
destinations) actually works. But not in these series.
141: Output changed: prepatch, "Node is in use" comes from bdrv_has_blk
check inside qmp_blockdev_del. But we've dropped block-copy blk
objects, so no more blk objects on source bs (job blk is on backup-top
filter bs). New message is from op-blocker, which is the next check in
qmp_blockdev_add.
257: The test wants to emulate guest write during backup. They should
go to filter node, not to original source node, of course. Therefore we
need to specify filter node name and use it.

Launching the destination VM before the source VM gives us a regression
test for HEAD^:
The guest device causes a read from the disk image through
guess_disk_lchs(). This will not work if the first sector (containing
the partition table) is yet unallocated, we use COR, and the node is
inactive.
By launching the source VM before the destination, however, the COR
filter on the source will allocate that area in the image shared between
both VMs, thus the problem will not become apparent.
Switching the launch order causes the sector to still be unallocated
when guess_disk_lchs() runs on the inactive node in the destination VM,
and thus we get our test case.

server reported: Option 0x7 not permitted before TLS
The problem? As specified, -drive is trying to pass tls-creds to the
raw format driver instead of the nbd protocol driver, but before we
get to the point where we can detect that raw doesn't know what to do
with tls-creds, the nbd driver has already failed because the server
complained. The fix to the broken command line? Pass
'...,file.tls-creds=tls0' to ensure the tls-creds option is handed to
nbd, not raw. But since the error message was rather cryptic, I'm
trying to improve the error message.
With this patch, the error message adds a line:
qemu-system-x86_64: -drive id=drive_image1,if=none,snapshot=off,aio=threads,cache=none,format=raw,file=nbd:localhost:9000,werror=stop,rerror=stop,tls-creds=tls0: TLS negotiation required before option 7 (go)
Did you forget a valid tls-creds?
server reported: Option 0x7 not permitted before TLS
And with luck, someone grepping for that error message will find this
commit message and figure out their command line mistake. Sadly, the
only mention of file.tls-creds in our docs relates to an --image-opts
use of PSK encryption with qemu-img as the client, rather than x509
certificate encryption with qemu-kvm as the client.

With the '-valgrind' option, let all the QEMU processes be run under
the Valgrind tool. The Valgrind own parameters may be set with its
environment variable VALGRIND_OPTS, e.g.
$ VALGRIND_OPTS="--leak-check=yes" ./check -valgrind <test#>
or they may be listed in the Valgrind checked file ./.valgrindrc or
~/.valgrindrc like
--memcheck:leak-check=no
--memcheck:track-origins=yes
To exclude a specific process from running under the Valgrind, the
corresponding environment variable VALGRIND_QEMU_<name> is to be set
to the empty string:
$ VALGRIND_QEMU_IO= ./check -valgrind <test#>
When QEMU-IO process is being killed, the shell report refers to the
text of the command in _qemu_io_wrapper(), which was modified with this
patch. So, the benchmark output for the tests 039, 061 and 137 is to be
changed also.

We have two Python unittest-style tests that test NBD. As such, they
should specify supported_protocols=['nbd'] so they are skipped when the
user wants to test some other protocol.
Furthermore, we should restrict their choice of formats to 'raw'. The
idea of a protocol/format combination is to use some format over some
protocol; but we always use the raw format over NBD. It does not really
matter what the NBD server uses on its end, and it is not a useful test
of the respective format driver anyway.

[eblake: update iotests 223, 233]
When creating a read-only image, we are still advertising support for
TRIM and WRITE_ZEROES to the client, even though the client should not
be issuing those commands. But seeing this requires looking across
multiple functions:
All callers to nbd_export_new() passed a single flag based solely on
whether the export allows writes. Later, we then pass a constant set
of flags to nbd_negotiate_options() (namely, the set of flags which we
always support, at least for writable images), which is then further
dynamically modified with NBD_FLAG_SEND_DF based on client requests
for structured options. Finally, when processing NBD_OPT_EXPORT_NAME
or NBD_OPT_EXPORT_GO we bitwise-or the original caller's flag with the
runtime set of flags we've built up over several functions.
Let's refactor things to instead compute a baseline of flags as soon
as possible which gets shared between multiple clients, in
nbd_export_new(), and changing the signature for the callers to pass
in a simpler bool rather than having to figure out flags. We can then
get rid of the 'myflags' parameter to various functions, and instead
refer to client for everything we need (we still have to perform a
bitwise-OR for NBD_FLAG_SEND_DF during NBD_OPT_EXPORT_NAME and
NBD_OPT_EXPORT_GO, but it's easier to see what is being computed).
This lets us quit advertising senseless flags for read-only images, as
well as making the next patch for exposing FAST_ZERO support easier to
write.

[eblake: improve commit message, update iotest 223]
A server may have a reason to reject a request for structured replies,
beyond just not recognizing them as a valid request; similarly, it may
have a reason for rejecting a request for a meta context. It doesn't
hurt us to continue talking to such a server; otherwise 'qemu-nbd
--list' of such a server fails to display all available details about
the export.
Encountered when temporarily tweaking nbdkit to reply with
NBD_REP_ERR_POLICY. Present since structured reply support was first
added (commit d795299b reused starttls handling, but starttls is
different in that we can't fall back to other behavior on any error).
Note that for an unencrypted client trying to connect to a server that
requires encryption, this defers the point of failure to when we
finally execute a strict command (such as NBD_OPT_GO or NBD_OPT_LIST),
now that the intermediate NBD_OPT_STRUCTURED_REPLY does not diagnose
NBD_REP_ERR_TLS_REQD as fatal; but as the protocol eventually gets us
to a command where we can't continue onwards, the changed error
message doesn't cause any security concerns.

[eblake: fix iotest 233]
The NBD specification defines NBD_FLAG_CAN_MULTI_CONN, which can be
advertised when the server promises cache consistency between
simultaneous clients (basically, rules that determine what FUA and
flush from one client are able to guarantee for reads from another
client). When we don't permit simultaneous clients (such as qemu-nbd
without -e), the bit makes no sense; and for writable images, we
probably have a lot more work before we can declare that actions from
one client are cache-consistent with actions from another. But for
read-only images, where flush isn't changing any data, we might as
well advertise multi-conn support. What's more, advertisement of the
bit makes it easier for clients to determine if 'qemu-nbd -e' was in
use, where a second connection will succeed rather than hang until the
first client goes away.
This patch affects qemu as server in advertising the bit. We may want
to consider patches to qemu as client to attempt parallel connections
for higher throughput by spreading the load over those connections
when a server advertises multi-conn, but for now sticking to one
connection per nbd:// BDS is okay.

It is possible to enable only a subset of the block drivers with the
"--block-drv-rw-whitelist" option of the "configure" script. All other
drivers are marked as unusable (or only included as read-only with the
"--block-drv-ro-whitelist" option). If an iotest is now using such a
disabled block driver, it is failing - which is bad, since at least the
tests in the "auto" group should be able to deal with this situation.
Thus let's introduce a "_require_drivers" function that can be used by
the shell tests to check for the availability of certain drivers first,
and marks the test as "not run" if one of the drivers is missing.
This patch mainly targets the test in the "auto" group which should
never fail in such a case, but also improves some of the other tests
along the way. Note that we also assume that the "qcow2" and "file"
drivers are always available - otherwise it does not make sense to
run "make check-block" at all (which only tests with qcow2 by default).

When creating an image with preallocation "off" or "falloc", the first
block of the image is typically not allocated. When using Gluster
storage backed by XFS filesystem, reading this block using direct I/O
succeeds regardless of request length, fooling alignment detection.
In this case we fallback to a safe value (4096) instead of the optimal
value (512), which may lead to unneeded data copying when aligning
requests. Allocating the first block avoids the fallback.
Since we allocate the first block even with preallocation=off, we no
longer create images with zero disk size:
$ ./qemu-img create -f raw test.raw 1g
Formatting 'test.raw', fmt=raw size=1073741824
$ ls -lhs test.raw
4.0K -rw-r--r--. 1 nsoffer nsoffer 1.0G Aug 16 23:48 test.raw
And converting the image requires additional cluster:
$ ./qemu-img measure -f raw -O qcow2 test.raw
required size: 458752
fully allocated size: 1074135040
When using format like vmdk with multiple files per image, we allocate
one block per file:
$ ./qemu-img create -f vmdk -o subformat=twoGbMaxExtentFlat test.vmdk 4g
Formatting 'test.vmdk', fmt=vmdk size=4294967296 compat6=off hwversion=undefined subformat=twoGbMaxExtentFlat
$ ls -lhs test*.vmdk
4.0K -rw-r--r--. 1 nsoffer nsoffer 2.0G Aug 27 03:23 test-f001.vmdk
4.0K -rw-r--r--. 1 nsoffer nsoffer 2.0G Aug 27 03:23 test-f002.vmdk
4.0K -rw-r--r--. 1 nsoffer nsoffer 353 Aug 27 03:23 test.vmdk
I did quick performance test for copying disks with qemu-img convert to
new raw target image to Gluster storage with sector size of 512 bytes:
for i in $(seq 10); do
rm -f dst.raw
sleep 10
time ./qemu-img convert -f raw -O raw -t none -T none src.raw dst.raw

The regular expressions in the "check" script currently expect that there
is always a space after the test number in the group file, so you can't
have a test in there without a group unless the line still ends with a
space - which is quite error prone since some editors might remove spaces
at the end of lines automatically.
Thus let's fix the regular expressions so that it is also possible to
have lines with one test number only in the group file.

When qemu quits, all throttling should be ignored. That means, if there
is a mirror job running from a throttled node, it should be cancelled
immediately and qemu close without blocking.

Before the previous patches, the first case resulted in a failed
assertion (which is noted as qemu receiving a SIGABRT in the test
output), and the second usually triggered a segmentation fault.

If a test has issued a quit command already (which may be useful to do
explicitly because the test wants to show its effects),
QEMUMachine.shutdown() should not do so again. Otherwise, the VM may
well return an ECONNRESET which will lead QEMUMachine.shutdown() to
killing it, which then turns into a "qemu received signal 9" line.

The Valgrind tool reports about the uninitialised buffer 'buf'
instantiated on the stack of the function guess_disk_lchs().
Pass 'read-zeroes=on' to the null block driver to make it deterministic.
The output of the tests 051, 186 and 227 now includes the parameter
'read-zeroes'. So, the benchmark output files are being changed too.

This tests that the stream job exits cleanly (without abort) when the
top node is read-only and cannot be reopened read/write.
