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.

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)

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
with the message:

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.

Commit 2cc4d1c5ea ("tests/check-block: Skip iotests when sanitizers
are enabled") changed iotests to skip when sanitizers are enabled.
The rationale is that AddressSanitizer emits warnings and reports leaks,
which results in test breakage. Later, sanitizers that are enabled for
production environments (safe-stack and cfi-icall) were exempted.
However, this approach has a few problems.
- It requires rebuild to disable sanitizers if the existing build has
them enabled.
- It disables other useful non-production sanitizers.
- The exemption of safe-stack and cfi-icall is not correctly
implemented, so qemu-iotests are incorrectly enabled whenever either
safe-stack or cfi-icall is enabled *and*, even if there is another
sanitizer like AddressSanitizer.
To solve these problems, direct AddressSanitizer warnings to separate
files to avoid changing the test results, and selectively disable
leak detection at runtime instead of requiring to disable all
sanitizers at buildtime.

Detaching filters using detach_subchain=true can cause segfaults as
described in #3149.
More specifically, this was observed when executing concurrent
block-stream and query-named-block-nodes. block-stream adds a
copy-on-read filter as the main BDS for the blockjob; that filter was
dropped with detach_subchain=true but not unref'd until the the blockjob
was free'd. Because query-named-block-nodes assumes that a filter will
always have exactly one child, it caused a segfault when it observed the
detached filter. Stacktrace:

As discussed in 20251024-second-fix-3149-v1-1-d997fa3d5ce2@canonical.com,
a filter should not exist without children in the first place; therefore,
drop the parameter entirely as it is only used for filters.
This is a partial revert of 3108a15cf0.
After this change, a blockdev-backup job's copy-before-write filter will
hold references to its children until the filter is unref'd. This causes
an additional flush during bdrv_close, so also update iotest 257.

AioContext's glib integration only supports ppoll(2) file descriptor
monitoring. epoll(7) and io_uring(7) disable themselves and switch back
to ppoll(2) when the glib event loop is used. The main loop thread
cannot use epoll(7) or io_uring(7) because it always uses the glib event
loop.
Future QEMU features may require io_uring(7). One example is uring_cmd
support in FUSE exports. Each feature could create its own io_uring(7)
context and integrate it into the event loop, but this is inefficient
due to extra syscalls. It would be more efficient to reuse the
AioContext's existing fdmon-io_uring.c io_uring(7) context because
fdmon-io_uring.c will already be active on systems where Linux io_uring
is available.
In order to keep fdmon-io_uring.c's AioContext operational even when the
glib event loop is used, extend FDMonOps with an API similar to
GSourceFuncs so that file descriptor monitoring can integrate into the
glib event loop.
A quick summary of the GSourceFuncs API:
- prepare() is called each event loop iteration before waiting for file
descriptors and timers.
- check() is called to determine whether events are ready to be
dispatched after waiting.
- dispatch() is called to process events.
More details here: https://docs.gtk.org/glib/struct.SourceFuncs.html
Move the ppoll(2)-specific code from aio-posix.c into fdmon-poll.c and
also implement epoll(7)- and io_uring(7)-specific file descriptor
monitoring code for glib event loops.
Note that it's still faster to use aio_poll() rather than the glib event
loop since glib waits for file descriptor activity with ppoll(2) and
does not support adaptive polling. But at least epoll(7) and io_uring(7)
now work in glib event loops.
Splitting this into multiple commits without temporarily breaking
AioContext proved difficult so this commit makes all the changes. The
next commit will remove the aio_context_use_g_source() API because it is
no longer needed.

test-nested-aio-poll relies on internal details of how fdmon-poll.c
handles AioContext polling. Skip it when other fdmon implementations are
in use.
The reason why fdmon-io_uring.c behaves differently from fdmon-poll.c is
that its fdmon_ops->need_wait() function returns true when
io_uring_enter(2) must be called (e.g. to submit pending SQEs).
AioContext polling is skipped when ->need_wait() returns true, so the
test case will never enter AioContext polling mode with
fdmon-io_uring.c.
Restrict this test to fdmon-poll.c and drop the
aio_context_use_g_source() call since it's no longer necessary.
Note that this test is only built on POSIX systems so it is safe to
include "util/aio-posix.h".

Add explicit validation for QAPI documentation formatting rules:
1. Lines must not exceed 70 columns in width (including '# ' prefix)
2. Sentences must be separated by two spaces
Example sections and literal :: blocks (seldom case) are excluded, we
don't require them to be <= 70, that would be too restrictive. Anyway,
they share common 80-columns recommendations (not requirements).
Add two simple tests, illustrating the change.

Currently, when postcopy starts, the source VM starts switchover and
sends a package containing the state of all non-postcopiable devices.
When the destination loads this package, the switchover is complete and
the destination VM starts. However, if the device state load fails or
the destination side crashes, the source side is already in
POSTCOPY_ACTIVE state and cannot be recovered, even when it has the most
up-to-date machine state as the destination has not yet started.
This patch introduces a new POSTCOPY_DEVICE state which is active while
the destination machine is loading the device state, is not yet running,
and the source side can be resumed in case of a migration failure.
Return-path is required for this state to function, otherwise it will be
skipped in favor of POSTCOPY_ACTIVE.
To transition from POSTCOPY_DEVICE to POSTCOPY_ACTIVE, the source
side uses a PONG message that is a response to a PING message processed
just before the POSTCOPY_RUN command that starts the destination VM.
Thus, this feature is effective even if the destination side does not
yet support this new state.

The x509 TLS credentials code will load the identity certs once to
perform sanity chcking on the certs, then discard the certificate
objects and let gnutls load them a second time.
This extends the previous QCryptoTLSCredsX509Files struct to also
hold the identity certificates & key loaded for sanity checking
and pass them on to gnutls, avoiding the duplicated loading.
The unit tests need updating because we now correctly diagnose the
error scenario where the cert PEM file exists, without its matching
key PEM file. Previously that error was mistakenly ignored.

We've seen a GitLab CI timeout failure in the test_pseries.py test,
where it appears likely that the test has hung in a self.qmp('quit')
call, but we don't have conclusive proof. Adding the QMP log category
to what we capture should help us diagnose this, at the cost of the
base.log file becoming significantly more verbose. The previous
commit to include the logger category name and function should at
least help understanding the more verbose logs.

As we collect debug logs from a wide range of code it becomes
increasingly confusing to understand where each log messages comes

based on the python __name__ symbol, aka the code module name.
Then "%(funcName)s" completes the story by identifying the function.

should be marked with an underscore, "when > then and when < now"
can be simplified to "now > when > then" and expectData doesn't conform
to the usual snake_case naming style.

Pylint complains about too many positional arguments for the __init__
function of the QEMUBitsMachine class, use a "*" to enforce argument
passing by names instead (which the calling sites are doing here already).
Second, use lazy logging when calling self.log.info() with a "%s" format
string, and drop a superfluous "else:" that is not necessary after a
"raise" statement.

pylint complains about bad indentation in two lines. Use 12 spaces
instead of 11 spaces to get it right.

TemporaryDirectory prefer explicit call to .cleanup() (or
use context manager). Otherwise it may produce a warning like:
/usr/lib/python3.10/tempfile.py:1008: \
ResourceWarning: Implicitly cleaning up \
<TemporaryDirectory '/tmp/qemu_func_test_sock_4esmf5ba'>
Currently, the only test using socket_dir() is
tests/functional/x86_64/test_vfio_user_client.py, and it does
print this warning, at least with python 3.10.12. With this commit,
the warning disappears.

This file does not use LinuxKernelTest directly (but AspeedTest),
so we can remove this unnecessary import here.

The "raise" without an Exception was a real problem, the other
spots are rather cosmetics.
