Alex Bennée 4f575c08ca tests/softfloat: always do quick softfloat tests
Some operations take a long time and enabling "-l 2 -r all" can take
more than a day which is stretching the definition of a "slow" test.
Lets default to the quick test and leave a note for those who wish to
run by hand.

Thomas Huth d99e97e691 configure: Add a proper check for openpty() in libutil
On Linux (and maybe some BSDs), we require libutil for the openpty()
function. However, this library is not available on some other systems, so
we currently use a fragile if-statement in the configure script to check
whether we need the library or not. Unfortunately, we also hard-coded a
"-lutil" in the tests/Makefile.include file, so this breaks the build on
Solaris, for example (see buglink below). To fix the issue, add the "-lutil"
to "libs_tools" in the configure script instead, then this gets properly
propagated to the tests, too.
And while we're at it, also replace the fragile if-statement in the confi-
gure script with a proper link-check for the availability of this function.

Kevin Wolf 4720cbeea1 block: Fix hangs in synchronous APIs with iothreads
In the block layer, synchronous APIs are often implemented by creating a
coroutine that calls the asynchronous coroutine-based implementation and
then waiting for completion with BDRV_POLL_WHILE().

For this to work with iothreads (more specifically, when the synchronous
API is called in a thread that is not the home thread of the block
device, so that the coroutine will run in a different thread), we must
make sure to call aio_wait_kick() at the end of the operation. Many
places are missing this, so that BDRV_POLL_WHILE() keeps hanging even if
the condition has long become false.

Note that bdrv_dec_in_flight() involves an aio_wait_kick() call. This
corresponds to the BDRV_POLL_WHILE() in the drain functions, but it is
generally not enough for most other operations because they haven't set
the return value in the coroutine entry stub yet. To avoid race
conditions there, we need to kick after setting the return value.

The race window is small enough that the problem doesn't usually surface
in the common path. However, it does surface and causes easily
reproducible hangs if the operation can return early before even calling
bdrv_inc/dec_in_flight, which many of them do (trivial error or no-op
success paths).

The bug in bdrv_truncate(), bdrv_check() and bdrv_invalidate_cache() is
slightly different: These functions even neglected to schedule the
coroutine in the home thread of the node. This avoids the hang, but is
obviously wrong, too. Fix those to schedule the coroutine in the right
AioContext in addition to adding aio_wait_kick() calls.

Markus Armbruster a95291007b qapi: Eliminate indirection through qmp_event_get_func_emit()
The qapi_event_send_FOO() functions emit events like this:

    QMPEventFuncEmit emit;

    emit = qmp_event_get_func_emit();
    if (!emit) {
        return;
    }

    qmp = qmp_event_build_dict("FOO");
    [put event arguments into @qmp...]

    emit(QAPI_EVENT_FOO, qmp);

The value of qmp_event_get_func_emit() depends only on the program:

* In qemu-system-FOO, it's always monitor_qapi_event_queue.

* In tests/test-qmp-event, it's always event_test_emit.

* In all other programs, it's always null.

This is exactly the kind of dependence the linker is supposed to
resolve; we don't actually need an indirection.

Note that things would fall apart if we linked more than one QAPI
schema into a single program: each set of qapi_event_send_FOO() uses
its own event enumeration, yet they share a single emit function.
Which takes the event enumeration as an argument.  Which one if
there's more than one?

More seriously: how does this work even now?  qemu-system-FOO wants
QAPIEvent, and passes a function taking that to
qmp_event_set_func_emit().  test-qmp-event wants test_QAPIEvent, and
passes a function taking that to qmp_event_set_func_emit().

It works by type trickery, of course:

    typedef void (*QMPEventFuncEmit)(unsigned event, QDict *dict);

    void qmp_event_set_func_emit(QMPEventFuncEmit emit);

    QMPEventFuncEmit qmp_event_get_func_emit(void);

We use unsigned instead of the enumeration type.  Relies on both
enumerations boiling down to unsigned, which happens to be true for
the compilers we use.

Clean this up as follows:

* Generate qapi_event_send_FOO() that call PREFIX_qapi_event_emit()
  instead of the value of qmp_event_set_func_emit().

* Generate a prototype for PREFIX_qapi_event_emit() into
  qapi-events.h.

* PREFIX_ is empty for qapi/qapi-schema.json, and test_ for
  tests/qapi-schema/qapi-schema-test.json.  It's qga_ for
  qga/qapi-schema.json, and doc-good- for
  tests/qapi-schema/doc-good.json, but those don't define any events.

* Rename monitor_qapi_event_queue() to qapi_event_emit() instead of
  passing it to qmp_event_set_func_emit().  This takes care of
  qemu-system-FOO.

* Rename event_test_emit() to test_qapi_event_emit() instead of
  passing it to qmp_event_set_func_emit().  This takes care of
  tests/test-qmp-event.

* Add a qapi_event_emit() that does nothing to stubs/monitor.c.  This
  takes care of all other programs that link code emitting QMP events.

* Drop qmp_event_set_func_emit(), qmp_event_get_func_emit().

listed, so in order to be accurate it's necessary to list those that
will run.  The same is true for "check-clean".

Then, to give a better visual impression of the differences in the

Paolo Bonzini 9df43317b8 test: replace gtester with a TAP driver
gtester is deprecated by upstream glib (see for example the announcement
at https://blog.gtk.org/2018/07/11/news-from-glib-2-58/) and it does
not support tests that call g_test_skip in some glib stable releases.

glib suggests instead using Automake's TAP support, which gtest itself
supports since version 2.38 (QEMU's minimum requirement is 2.40).
We do not support Automake, but we can use Automake's code to beautify
the TAP output.  I chose to use the Perl copy rather than the shell/awk
one, with some changes so that it can accept TAP through stdin, in order
to reuse Perl's TAP parsing package.  This also avoids duplicating the
parser between tap-driver.pl and tap-merge.pl.

Thomas Huth c2077ec2d9 tests/display-vga: Enable virtio-vga test
There are some "#ifdef CONFIG_VIRTIO_VGA" in the code here which
do not work as expected: CONFIG_VIRTIO_VGA is a Makefile switch,
but not a CPP macro, so the "guarded" code currently simply never
gets enabled.

So enable this code now unconditionally, with some runtime switches
for the architectures that have the VIRTIO_VGA device enabled by
default. Looking at the other if-statement in the main function here,
it also seems like this test was originally supposed to be running
on "mips" and "alpha", too, so enable it now for these architectures
in the Makefile, too.

Paolo Bonzini 87ad860c62 nvme: fix out-of-bounds access to the CMB
Because the CMB BAR has a min_access_size of 2, if you read the last
byte it will try to memcpy *2* bytes from n->cmbuf, causing an off-by-one
error.  This is CVE-2018-16847.

Another way to fix this might be to register the CMB as a RAM memory
region, which would also be more efficient.  However, that might be a
change for big-endian machines; I didn't think this through and I don't
know how real hardware works.  Add a basic testcase for the CMB in case
somebody does this change later on.

Let's provide a convenient way for QEMU developers to run them,

Also, while the Avocado test runner will take care of creating a
location to save test results to, it was understood that it's better

Eric Blake 7a6c377f6b tests: Prevent more accidental test disabling
GNU make is perfectly happy to use 'check-FOO-y += bar' to
initialize check-FOO-y.  (GNU Automake strictly insists that
you cannot use += until after an initial = per variable, but
thankfully we aren't using automake).

As we have had more than one instance where copy-and-paste of
'check-FOO-y = bar' from a first test under category FOO into
an additional test, which ends up disabling the first (see
commits 992159c7 and 4429532b), it's better to just always use
the form that survives copy-and-paste, even for categories that
don't currently add more than one test.

Wei Huang c02b37814c tests: Add migration test for aarch64
This patch adds migration test support for aarch64. The test code, which
implements the same functionality as x86, is booted as a kernel in qemu.
Here are the design choices we make for aarch64:

 * We choose this -kernel approach because aarch64 QEMU doesn't provide a
   built-in fw like x86 does. So instead of relying on a boot loader, we
   use -kernel approach for aarch64.
 * The serial output is sent to PL011 directly.
 * The physical memory base for mach-virt machine is 0x40000000. We change
   the start_address and end_address for aarch64.

In addition to providing the binary, this patch also includes the source
code and the build script in tests/migration/aarch64. So users can change
the source and/or re-compile the binary as they wish.
