  cirrus.yml: Fix the MSYS2 task (2021-05-14 13:11:48 +0200)

----------------------------------------------------------------
* Replace YAML anchors by extends in the gitlab-CI yaml files
* Many small qtest fixes (e.g. to fix issues discovered by Coverity)
* Poison more config switches in common code
* Fix the failing Travis-CI and Cirrus-CI tasks
----------------------------------------------------------------

Note: This PR replaces my PR from May 3rd - the moxie removal has
      already been merged via Markus' tree, and I addes some other
      CI- and qtest related patches instead.

+Troubleshooting unavailable tests

+
+It is possible to troubleshoot unavailable tests by running::

+  ...
+  # }
+
+The ``virtio-net-tests/announce-self`` test is listed as "available" in the
+"ALL QGRAPH NODES" output. This means the test will execute. We can follow the
+qgraph path in the "ALL QGRAPH EDGES" output as follows: '' -> 'x86_64/pc' ->
+'i440FX-pcihost' -> 'pci-bus-pc' -> 'pci-bus' -> 'virtio-net-pci' ->
+'virtio-net'. The root of the qgraph is '' and the depth first search begins
+there.
+
+The ``arm/raspi`` machine node is listed as "UNAVAILABLE". Although it is
+reachable from the root via '' -> 'arm/raspi2' the node is unavailable because
+the QEMU binary did not list it when queried by the framework. This is expected
+because we used the ``qemu-system-x86_64`` binary which does not support ARM
+machine types.
+
+If a test is unexpectedly listed as "UNAVAILABLE", first check that the "ALL
+QGRAPH EDGES" output reports edge connectivity from the root ('') to the test.
+If there is no connectivity then the qgraph nodes were not set up correctly and
+the driver or test code is incorrect. If there is connectivity, check the
+availability of each node in the path in the "ALL QGRAPH NODES" output. The
+first unavailable node in the path is the reason why the test is unavailable.
+Typically this is because the QEMU binary lacks support for the necessary
+machine type or device.

[PULL 07/20] libqtest: refuse QTEST_QEMU_BINARY=qemu-kvm

[Thomas Huth]

From: Stefan Hajnoczi <stefanha@redhat.com>

Some downstreams rename the QEMU binary to "qemu-kvm". This breaks
qtest_get_arch(), which attempts to parse the target architecture from
the QTEST_QEMU_BINARY environment variable.

Print an error instead of returning the architecture "kvm". Things fail
in weird ways when the architecture string is bogus.

Arguably qtests should always be run in a build directory instead of
against an installed QEMU. In any case, printing a clear error when this
happens is helpful.

Since this is an error that is triggered by the user and not a test
failure, use exit(1) instead of abort(). Change the existing abort()
call in qtest_get_arch() to exit(1) too for the same reason and to be
consistent.

[PULL 08/20] util/compatfd.c: Replaced a malloc call with g_malloc.

[Thomas Huth]

From: Mahmoud Mandour <ma.mandourr@gmail.com>

Replaced a call to malloc() and its respective call to free()
with g_malloc() and g_free().

g_malloc() is preferred more than g_try_* functions, which
return NULL on error, when the size of the requested
allocation  is small. This is because allocating few
bytes should not be a problem in a healthy system.
Otherwise, the system is already in a critical state.

Subsequently, removed NULL-checking after g_malloc().

[PULL 09/20] tests/qtest/ahci-test.c: Calculate iso_size with 64-bit arithmetic

[Thomas Huth]

From: Peter Maydell <peter.maydell@linaro.org>

Coverity notes that when calculating the 64-bit iso_size value in
ahci_test_cdrom() we actually only do it with 32-bit arithmetic.
This doesn't matter for the current test code because nsectors is
always small; but adding the cast avoids the coverity complaints.

[PULL 10/20] tests/qtest/npcm7xx_pwm-test.c: Avoid g_assert_true() for non-test assertions

[Thomas Huth]

From: Peter Maydell <peter.maydell@linaro.org>

In the glib API, the distinction between g_assert() and
g_assert_true() is that the former is for "bug, terminate the
application" and the latter is for "test check, on failure either
terminate or just mark the testcase as failed".  For QEMU, g_assert()
is always fatal, so code can assume that if the assertion fails
execution does not proceed, but this is not true of g_assert_true().

In npcm7xx_pwm-test, the pwm_index() and pwm_module_index() functions
include some assertions that are just guarding against possible bugs
in the test code that might lead us to out-of-bounds array accesses.
These should use g_assert() because they aren't part of what the test
is testing and the code does not correctly handle the case where the
condition was false.

This fixes some Coverity issues where Coverity knows that
g_assert_true() can continue when the condition is false and
complains about the possible array overrun at various callsites.

From: Peter Maydell <peter.maydell@linaro.org>

In rtc-test.c we know that s is non-NULL because qtest_start()
will return a non-NULL value, and we assume this when we
pass s to qtest_irq_intercept_in(). So we can drop the
initial assignment of NULL and the "if (s)" condition at
the end of the function.

[PULL 17/20] configure: Poison all current target-specific #defines

[Thomas Huth]

We are generating a lot of target-specific defines in the *-config-devices.h
and *-config-target.h files. Using them in common code is wrong and leads
to very subtle bugs since a "#ifdef CONFIG_SOMETHING" is not working there
as expected. To avoid these issues, we are already poisoning many of the
macros in include/exec/poison.h - but it's cumbersome to maintain this
list manually. Thus let's generate an additional list of poisoned macros
automatically from the current config switches - this should give us a
much better test coverage via the different CI configurations.

Note that CONFIG_TCG (which is also defined in config-host.h) and
CONFIG_USER_ONLY are special, so we have to filter these out.

[PULL 18/20] tests/qtest/migration-test: Use g_autofree to avoid leaks on error paths

[Thomas Huth]

From: Peter Maydell <peter.maydell@linaro.org>

Coverity notices that several places in the migration-test code fail
to free memory in error-exit paths.  This is pretty unimportant in
test case code, but we can avoid having to manually free the memory
entirely by using g_autofree.

The places where Coverity spotted a leak were relating to early exits
not freeing 'uri' in test_precopy_unix(), do_test_validate_uuid(),
migrate_postcopy_prepare() and test_migrate_auto_converge().  This
patch converts all the string-allocation in the test code to
g_autofree for consistency.

Fixes: Coverity CID 1432313, 1432315, 1432352, 1432364

[PULL 19/20] pc-bios/s390-ccw: Fix inline assembly for older versions of Clang

[Thomas Huth]

Clang versions before v11.0 insist on having the %rX or %cX register
names instead of just a number. Since our Travis-CI is currently
still using Clang v6.0, we have to fix this to avoid failing jobs.

[PULL 20/20] cirrus.yml: Fix the MSYS2 task

[Thomas Huth]

The MSYS2 task in the Cirrus-CI is currently failing with error messages
like this:

 warning: database file for 'ucrt64' does not exist (use '-Sy' to download)
 :: Starting core system upgrade...
  there is nothing to do
 :: Starting full system upgrade...
 error: failed to prepare transaction (could not find database)

Seems like it can be fixed by switching to a newer release and by refreshing
the database one more time after changing the /etc/pacman.conf file.
