Christian Schoenebeck 23820025af libqos/qgraph_internal: add qos_printf() and qos_printf_literal()
These two are macros wrapping regular printf() call. They are intended
to be used instead of calling printf() directly in order to avoid
breaking TAP output format.

TAP output format is enabled by using --tap command line argument.
Starting with glib 2.62 it is enabled by default.

Unfortunately there is currently no public glib API available to check
whether TAP output format is enabled. For that reason qos_printf()
simply always prepends a '#' character for now.

Christian Schoenebeck f6a2c6eee7 libqos/qgraph: add qos_node_create_driver_named()
So far the qos subsystem of the qtest framework had the limitation
that only one instance of the same official QEMU (QMP) driver name
could be created for qtests. That's because a) the created qos
node names must always be unique, b) the node name must match the
official QEMU driver name being instantiated and c) all nodes are
in a global space shared by all tests.

This patch removes this limitation by introducing a new function
qos_node_create_driver_named() which allows test case authors to
specify a node name being different from the actual associated
QEMU driver name. It fills the new 'qemu_name' field of
QOSGraphNode for that purpose.

Adjust build_driver_cmd_line() and qos_graph_node_set_availability()
to correctly deal with either accessing node name vs. node's
qemu_name correctly.

Peter Maydell 0250edf1eb tests/qtest/libqos/ahci.c: Avoid NULL dereference in ahci_exec()
In ahci_exec() we attempt to permit the caller to pass a NULL pointer
for opts_in (in which case we use a default set of options).  However
although we check for NULL when setting up the opts variable at the
top of the function, we unconditionally dereference opts_in at the
end of the function as part of freeing the opts->buffer.

Switch to checking whether the final buffer is the same as the
buffer we started with, instead of assuming the value we started
with is always opts_in->buffer.

At the moment all the callers pass a non-NULL opts argument, so
we never saw any crashes in practice.

So let's just do that and log an info-level message at least, because we
actually only care if the required directory exists and we do have an
existence check for that in place already.

Christian Schoenebeck 136b7af227 tests/9pfs: fix test dir for parallel tests
Use mkdtemp() to generate a unique directory for the 9p 'local' tests.

This fixes occasional 9p test failures when running 'make check -jN' if
QEMU was compiled for multiple target architectures, because the individual
architecture's test suites would run in parallel and interfere with each
other's data as the test directory was previously hard coded and hence the
same directory was used by all of them simultaniously.

This also requires a change how the test directory is created and deleted:
As the test path is now randomized and virtio_9p_register_nodes() being
called in a somewhat undeterministic way, that's no longer an appropriate
place to create and remove the test directory. Use a constructor and
destructor function for creating and removing the test directory instead.
Unfortunately libqos currently does not support setup/teardown callbacks
to handle this more cleanly.

The constructor functions needs to be in virtio-9p-test.c, not in
virtio-9p.c, because in the latter location it would cause all apps that
link to libqos (i.e. entirely unrelated test suites) to create a 9pfs
test directory as well, which would even break other test suites.

Christian Schoenebeck 051f0e5be1 tests/9pfs: wipe local 9pfs test directory
Before running the first 9pfs test case, make sure the test directory
for running the 9pfs 'local' tests on is entirely empty. For that
reason simply delete the test directory (if any) before (re)creating
it on test suite startup.

Note: The preferable precise behaviour would be the test directory
only being wiped once *before* a test suite run. Right now the test
directory is also wiped at the *end* of a test suite run because
libqos is calling the virtio_9p_register_nodes() callback for some
reason also when a test suite completed. This is suboptimal as
developers cannot immediately see what files and directories the
9pfs local tests created precisely after the test suite completed.
But fortunately the test directory is not wiped if some test failed.
So it is probably not worth it drilling another hole into libqos
for this issue.

Christian Schoenebeck 3a565c641a tests/9pfs: introduce local tests
This patch introduces 9pfs test cases using the 9pfs 'local'
filesystem driver which reads/writes/creates/deletes real files
and directories.

In this initial version, there is only one local test which actually
only checks if the 9pfs 'local' device was created successfully.

Before the 9pfs 'local' tests are run, a test directory 'qtest-9p-local'
is created (with world rwx permissions) under the current working
directory. At this point that test directory is not auto deleted yet.

This is intended to solve the race in regard to ordering of qmp events

In addition to that, define qtest_qmp_event_ref a function which only scans
the buffer that qtest_qmp_receive stores the events to.  This is intended
for callers that are only interested in events that were received during
the last call to the qtest_qmp_receive.

Paolo Bonzini c138156ba5 meson: fix libqos linking
Add genh to the sources to avoid race conditions between QAPI
file generation and libqos compilation.

Make the name_suffix .fa for consistency with other link_whole
static libraries and to work around a Meson issue where
lots of linker flags are placed between -Wl,--start-group and
-Wl,--end-group and this breaks the fork-fuzz.ld linker script.

qmp_assert_error_class() does more than just assert: it also unrefs
the @rsp argument.  Rename to qmp_expect_error_and_unref() to reduce
confusion.

Markus Armbruster a56f3cdbdf fuzz: Simplify how we compute available machines and types
apply_to_qlist(), apply_to_node() work with QObjects.  This is
designed for use by tests/qtest/qos-test.c, which gets the data in
that form via QMP.  Goes back to commit fc281c8020 "tests: qgraph API
for the qtest driver framework".

Commit 275ab39d86 "fuzz: add support for qos-assisted fuzz targets"
added another user: qtest/fuzz/qos_fuzz.c.  To get the data as
QObjects, it uses qmp_marshal_query_machines() and
qmp_marshal_qom_list_types().

All this code is rather cumbersome.  Switch to working with generated
QAPI types instead:

* Replace apply_to_qlist() & friends by machines_apply_to_node() and
  types_apply_to_node().

* Have qos_fuzz.c use qmp_query_machines() and qmp_qom_list_types()
  instead.

* Have qos_test.c convert from QObject to the QAPI types.

There should no longer be a reason to prevent TCG providing FWNMI.
System Reset interrupts are generated to the guest with nmi monitor
command and H_SIGNAL_SYS_RESET. Machine Checks can not be injected
currently, but this could be implemented with the mce monitor cmd
similarly to i386.

Philippe Mathieu-Daudé f7795e4096 misc: Replace zero-length arrays with flexible array member (automatic)
Description copied from Linux kernel commit from Gustavo A. R. Silva
(see [3]):

--v-- description start --v--

  The current codebase makes use of the zero-length array language
  extension to the C90 standard, but the preferred mechanism to
  declare variable-length types such as these ones is a flexible
  array member [1], introduced in C99:

  struct foo {
      int stuff;
      struct boo array[];
  };

  By making use of the mechanism above, we will get a compiler
  warning in case the flexible array does not occur last in the
  structure, which will help us prevent some kind of undefined
  behavior bugs from being unadvertenly introduced [2] to the
  Linux codebase from now on.

--^-- description end --^--

Do the similar housekeeping in the QEMU codebase (which uses
C99 since commit 7be41675f7).

All these instances of code were found with the help of the
following Coccinelle script:

  @@
  identifier s, m, a;
  type t, T;
  @@
   struct s {
      ...
      t m;
  -   T a[0];
  +   T a[];
  };
  @@
  identifier s, m, a;
  type t, T;
  @@
   struct s {
      ...
      t m;
  -   T a[0];
  +   T a[];
   } QEMU_PACKED;

Greg Kurz 63d57c8f91 tests: Silence various warnings with pseries
Some default features of the pseries machine are only available with
KVM. Warnings are printed when the pseries machine is used with another
accelerator:

qemu-system-ppc64: warning: TCG doesn't support requested feature,
cap-ccf-assist=on
qemu-system-ppc64: warning: Firmware Assisted Non-Maskable
Interrupts(FWNMI) not supported in TCG
qemu-system-ppc64: warning: TCG doesn't support requested feature,
cap-ccf-assist=on
qemu-system-ppc64: warning: Firmware Assisted Non-Maskable
Interrupts(FWNMI) not supported in TCG
qemu-system-ppc64: warning: TCG doesn't support requested feature,
cap-ccf-assist=on
qemu-system-ppc64: warning: Firmware Assisted Non-Maskable
Interrupts(FWNMI) not supported in TCG

This is annoying for CI since it usually runs without KVM. We already
disable features that emit similar warnings thanks to properties of
the pseries machine, but this is open-coded in various
places. Consolidate the set of properties in a single place. Extend it
to silence the above warnings. And use it in the various tests that
start pseries machines.
