Cédric Le Goater e37a0d514a tests/vhost-user-bridge.c: Fix const qualifier build errors with recent glibc
A recent change in glibc 2.42.9000 [1] changes the return type of
strstr() and other string functions to be 'const char *' when the
input is a 'const char *'. This breaks the build in :

../tests/vhost-user-bridge.c: In function ‘vubr_parse_host_port’:
../tests/vhost-user-bridge.c:749:15: error: initialization discards ‘const’ qualifier from pointer target type [-Werror=discarded-qualifiers]
  749 |     char *p = strchr(buf, ':');
      |               ^~~~~~

Fix this by using the glib g_strsplit() routine instead of strdup().

Alex Bennée 7242e51517 tests/tcg: honour the available QEMU binaries when running check-tcg
Currently configure can identify all the targets that have
cross-compilers available from the supplied target-list. By default
this is the default_target_list which is all possible targets we can
build.

At the same time the target list passed to meson is filtered down
depending on various factors including not building 64 bit targets on
32 bit hosts. As a result make check-tcg will erroneously attempt to
run tests for which we haven't built a QEMU.

Solve this by filtering the final list of TCG_TEST_TARGETS based on
what actually was configured by meson. Rename the variable that
configure spits out to TCG_TESTS_WITH_COMPILERS for clarity and to
avoid larger churn in the Makefile.

Peter Xu b1d67d86db tests/migration-test: Merge shmem_opts into memory_backend
The two parameters are more or less duplicated in migrate_args().  They all
describe the memory type.  When one is used, the other is not.

mem_type currently uses numa parameter to specify the memory backend, while
memory_backend (the two users of such uses "-machine memory-backend=ID").

This patch merges the use of the two variables so that we always generate a
memory object string and put it into "memory_backend" variable.  Now we can
drop shmem_opts parameter in the function.

Meanwhile we always use a memory-backend-* no matter which mem type is
used.  This brings mem_type to be aligned with memory_backend usage, then
we stick with this as this is flexible enough.

This paves way that we merge mem_type and memory_backend in MigrateStart.

Peter Xu b187a183b1 tests/migration-test: Introduce MemType
Some migration tests need to be run with shmem, the rest by default use
anonymous memory.

Introduce MemType and replace use_shmem with such a enumeration.  This
prepares for a 3rd type of memory to be tested for migration.

Careful readers may also already notice that MigrateStart has another field
called memory_backend, which makes the whole "memory type" definition
convoluted.  That'll be merged into MemType soon in a follow up patch.

When doing this, introduce some migrate_mem_type_*() helpers to do the
work for each memory type.

This commit was created with scripts/clean-includes:
 ./scripts/clean-includes --git tests tests

with one hand-edit to remove a now-empty #ifndef WIN32...#endif
from tests/qtest/dbus-display-test.c .

All .c should include qemu/osdep.h first.  The script performs three
related cleanups:

* Ensure .c files include qemu/osdep.h first.
* Including it in a .h is redundant, since the .c  already includes
  it.  Drop such inclusions.
* Likewise, including headers qemu/osdep.h includes is redundant.
  Drop these, too.

Running "./check -ssh 207" fails for me with lots of lines like this
in the output:

While looking closer at it, I noticed that the grep -v "\\^#" command
in this test is not working as expected - it is likely meant to filter
out the comment lines that are starting with a "#", but at least my
version of grep (GNU grep 3.11) does not work with the backslashes here.
There does not seem to be a compelling reason for these backslashes,
so let's simply drop them to fix this issue.

Eric Blake 24fd6d75b3 iotests: Add coverage of recent NBD qio deadlock fix
Test that all images in a qcow2 chain using an NBD backing file can be
served by the same process.  Prior to the recent QIONetListener fixes,
this test would demonstrate deadlock.

The test borrows heavily from the original formula by "John Doe" in
the gitlab bug, but uses a Unix socket rather than TCP to avoid port
contention, and uses a full-blown QEMU rather than qemu-storage-daemon
since both programs were impacted.

The test starts out with the even simpler task of directly adding an
NBD client without qcow2 chain ('client'), which also provokes the
deadlock; but commenting out the 'Adding explicit NBD client' section
will still show deadlock when reaching the 'Adding wrapper image...'.

Alberto Garcia 909852ba6b qemu-img rebase: don't exceed IO_BUF_SIZE in one operation
During a rebase operation data is copied from the backing chain into
the target image using a loop, and each iteration looks for a
contiguous region of allocated data of at most IO_BUF_SIZE (2 MB).

Once that region is found, and in order to avoid partial writes, its
boundaries are extended so they are aligned to the (sub)clusters of
the target image (see commit 12df580b).

This operation can however result in a region that exceeds the maximum
allowed IO_BUF_SIZE, crashing qemu-img.

This can be easily reproduced when the source image has a smaller
cluster size than the target image:

base <- int <- active

$ qemu-img create -f qcow2 base.qcow2 4M
$ qemu-img create -f qcow2 -F qcow2 -b base.qcow2 -o cluster_size=1M int.qcow2
$ qemu-img create -f qcow2 -F qcow2 -b int.qcow2  -o cluster_size=2M active.qcow2
$ qemu-io -c "write -P 0xff 1M 2M" int.qcow2
$ qemu-img rebase -F qcow2 -b base.qcow2 active.qcow2
qemu-img: qemu-img.c:4102: img_rebase: Assertion `written + pnum <= IO_BUF_SIZE' failed.

Thomas Huth 67685a2331 tests/qemu-iotest: Add more image formats to the thorough testing
Now that the "check" script is a little bit smarter with providing
a list of tests that are supported for an image format, we can also
add more image formats that can be used for generic block layer
testing. (Note: qcow1 and luks are not added because some tests
there currently fail, and other formats like bochs, cloop, dmg and
vvfat do not work with the generic tests and thus would only get
skipped if we'd tried to add them here)

Thomas Huth f00a45e9ca tests/qemu-iotests: Improve the dry run list to speed up thorough testing
When running the tests in thorough mode, e.g. with:

 make -j$(nproc) check SPEED=thorough

we currently always get a huge amount of total tests that the test
runner tries to execute (2457 in my case), but a big bunch of them are
only skipped (1099 in my case, meaning that only 1358 got executed).
This happens because we try to run the whole set of iotests for multiple
image formats while a lot of the tests can only run with one certain
format only and thus are marked as SKIP during execution. This is quite a
waste of time during each test run, and also unnecessarily blows up the
displayed list of executed tests in the console output.

Thus let's try to be a little bit smarter: If the "check" script is run
with "-n" and an image format switch (like "-qed") at the same time (which
is what we do for discovering the tests for the meson test runner already),
only report the tests that likely support the given format instead of
providing the whole list of all tests. We can determine whether a test
supports a format or not by looking at the lines in the file that contain
a "supported_fmt" or "unsupported_fmt" statement. This is only heuristics,
of course, but it is good enough for running the iotests via "make
check-block" - I double-checked that the list of executed tests does not
get changed by this patch, it's only the tests that are skipped anyway that
are now not run anymore.

This way the amount of total tests drops from 2457 to 1432 for me, and
the amount of skipped tests drops from 1099 to just 74 (meaning that we
still properly run 1432 - 74 = 1358 tests as we did before).

If qemu-img does not support throttling, test 184 currently skips

But that's wrong, it's not about the image format, it's about the
throttling not being available in qemu-img. Thus fix this by using
_notrun with a proper message instead.
