20 months agofuzz: Disable QEMU's SIG{INT,HUP,TERM} handlers
Alexander Bulekov [Wed, 14 Oct 2020 14:21:57 +0000 (10:21 -0400)] 
fuzz: Disable QEMU's SIG{INT,HUP,TERM} handlers

Prior to this patch, the only way I found to terminate the fuzzer was
either to:
 1. Explicitly specify the number of fuzzer runs with the -runs= flag
 2. SIGKILL the process with "pkill -9 qemu-fuzz-*" or similar

In addition to being annoying to deal with, SIGKILLing the process skips
over any exit handlers(e.g. registered with atexit()). This is bad,
since some fuzzers might create temporary files that should ideally be
removed on exit using an exit handler. The only way to achieve a clean
exit now is to specify -runs=N , but the desired "N" is tricky to
identify prior to fuzzing.

Why doesn't the process exit with standard SIGINT,SIGHUP,SIGTERM
signals? QEMU installs its own handlers for these signals in
os-posix.c:os_setup_signal_handling, which notify the main loop that an
exit was requested. The fuzzer, however, does not run qemu_main_loop,
which performs the main_loop_should_exit() check.  This means that the
fuzzer effectively ignores these signals. As we don't really care about
cleanly stopping the disposable fuzzer "VM", this patch uninstalls
QEMU's signal handlers. Thus, we can stop the fuzzer with
SIG{INT,HUP,TERM} and the fuzzing code can optionally use atexit() to
clean up temporary files/resources.

build: replace ninjatool with ninja

Now that the build is done entirely by Meson, there is no need
to keep the Makefile conversion.  Instead, we can ask Ninja about
the targets it exposes and forward them.

The main advantages are, from smallest to largest:

- reducing the possible namespace pollution within the Makefile

- removal of a relatively large Python program

- faster build because parsing Makefile.ninja is slower than
parsing build.ninja; and faster build after Meson runs because
we do not have to generate Makefile.ninja.

- tracking of command lines, which provides more accurate rebuilds

In addition the change removes the requirement for GNU make 3.82, which
was annoying on Mac, and avoids bugs on Windows due to ninjatool not
knowing how to convert Windows escapes to POSIX escapes.

win32: Simplify gmtime_r detection not depends on if _POSIX_C_SOURCE are defined on msys2/mingw

We remove the CONFIG_LOCALTIME_R detection option in configure, and move the check
existence of gmtime_r from configure into C header and source directly by using macro
`_POSIX_THREAD_SAFE_FUNCTIONS`.
Before this patch, the configure script are always assume the compiler doesn't define
_POSIX_C_SOURCE macro at all, but that's not true, because thirdparty library such
as ncursesw may define -D_POSIX_C_SOURCE in it's pkg-config file. And that C Flags will
added -D_POSIX_C_SOURCE into each QEMU_CFLAGS. And that's causing the following compiling error:

20 months agosoftmmu/vl: Be less verbose about missing KVM when running the qtests

softmmu/vl: Be less verbose about missing KVM when running the qtests

Some of the qtests use "-accel kvm -accel tcg" to run real guest code.
This causes some error messages when kvm is not available. We do not
really care about these messages since the fallback to tcg is expected
here. So let's silence them to avoid that they spoil the output of
the tests.

Unfortunately, we can not use the qtest_enabled() wrapper in this case,
since the qtest accelerator itself is not initialized. Thus we have to
test for the qtest_chrdev variable instead.

tests/migration: Allow longer timeouts

   a) The vCPU thread (100% flat out)

if (b) & (c) are slow for any reason - gcov+gperf or a slow host -

qtest: add fuzz test case

Currently the device fuzzer finds more and more issues.
For every fuzz case, we need not only the fixes but also
the corresponding test case. We can analysis the reproducer
for every case and find what happened in where and write
a beautiful test case. However the raw data of reproducer is not
friendly to analysis. It will take a very long time, even far more
than the fixes itself. So let's create a new file to hold all of
the fuzz test cases and just use the raw data to act as the test
case. This way nobody will be afraid of writing a test case for
the fuzz reproducer.

20 months agoqemu-iotests, qtest: rewrite test 067 as a qtest

qemu-iotests, qtest: rewrite test 067 as a qtest

Test 067 from qemu-iotests is executing QMP commands to hotplug
and hot-unplug disks, devices and blockdevs.  Because the power
of the text-based test harness is limited, it is actually limiting
the checks that it does, for example by skipping DEVICE_DELETED
events.

tests/qtest already has a similar test, drive_del-test.c.
We can merge them, and even reuse some of the existing code in
drive_del-test.c.  This will improve the quality of the test by
covering DEVICE_DELETED events and testing multiple architectures
(therefore covering multiple PCI hotplug mechanisms as well as s390x
virtio-ccw).

The only difference is that the new test will always use null-co:// for
the medium rather than qcow2 or raw, but this should be irrelevant for
what the test is covering.  For example there are no "qemu-img check"
runs in 067 that would check that the file is properly closed.

The new tests requires PCI hot-plug support, so drive_del-test
is moved from qemu-system-ppc to qemu-system-ppc64.

20 months agoqtest: check that drives are really appearing and disappearing

qtest: check that drives are really appearing and disappearing

Do not just trust the HMP commands to create and delete the drive, use
query-block to check that this is actually the case.
