Peter Maydell 6b699ae1be tests/vm: Increase timeout waiting for VM to boot to 5 minutes
The VM tests currently have a timeout of 2 minutes for trying
to connect to ssh. Since the guest VM has to boot from cold
to the point of accepting inbound ssh during this time, if the
host machine is heavily loaded it can spuriously time out.
Increase the timeout from 2 to 5 minutes.

Thomas Huth 410573aa2c tests/device-introspect: Test with all machines, not only with "none"
Certain device introspection crashes used to only happen if you were
using a certain machine, e.g. if the machine was using serial_hd() or
nd_table[], and a device was trying to use these in its instance_init
function, too.

To be able to catch these problems, let's extend the device-introspect
test to check the devices on all machine types, with and without the
"-nodefaults" parameter (since this makes a difference sometimes, too).
Since this is a rather slow operation, and most of the problems are
already handled by testing with the "none" machine only, the test with
all machines is only run in the "make check SPEED=slow" mode.

Thomas Huth d068521264 tests/device-introspection: Check that the qom-tree and qtree do not change
Introspection should not change the qom-tree / qtree, so we should check
this in the device-introspect-test, too. This patch helped to find lots
of instrospection bugs during the QEMU v3.0 soft/hard-freeze period in the
last two months.

Thomas Huth 1f4a0d81af tests: Skip old versioned machine types in quick testing mode
The tests that check something for all machine types currently spend
a lot of time checking old machine types (like "pc-i440fx-2.0" for
example). The chances that we find something new there in addition
to checking the latest version of a machine type are pretty low, so
we should not waste the time of the developers by testing this again
and again in the "quick" testing mode.
Thus let's add some code to determine whether we are testing a current
machine type or an old one, and only test the old types if we are
running in "SPEED=slow" mode.
This decreases the testing time quite a bit now, e.g. the qom-test
now finishes within 4 seconds for qemu-system-x86_64 instead of 30
seconds when testing all machines.

Thomas Huth 880b169a45 tests/migration-test: Silence the kvm_hv message by default
When running "make check" on a non-POWER host, the output is quite
distorted like this:

  [...]
  GTESTER check-qtest-nios2
  GTESTER check-qtest-or1k
  GTESTER check-qtest-ppc64
Skipping test: kvm_hv not available Skipping test: kvm_hv not available Skipping test: kvm_hv not available Skipping test: kvm_hv not available   GTESTER check-qtest-ppcemb
  GTESTER check-qtest-ppc
  GTESTER check-qtest-riscv32
  GTESTER check-qtest-riscv64
  [...]

Move the check to the beginning of the main function instead, so that
we do not have to test the condition again and again for each test,
and better use g_test_message() instead of g_print() here, like it is
also done in ufd_version_check() already.

Paolo Bonzini 06d09a018f tests: virtio: separate ccw tests from libqos
Because qtest does not support s390 channel I/O, s390 only performs smoke tests on
those few devices that do not have any functional tests.  Therefore, every time we
add functional tests for a virtio device, the choice is between removing
those tests from the s390 suite (so that s390 actually _loses_ coverage)
or sprinkling the test with architecture checks.

This patch simply creates a ccw-specific test that only performs smoke tests on
all virtio-ccw devices.  If channel I/O support is ever added to qtest and libqos,
then this file can go away.  In the meanwhile, it simplifies maintenance and
makes sure that all virtio devices are tested.

Hervé Poussineau 54c86f5a48 hw/ppc: deprecate the machine type 'prep', replaced by '40p'
- prep machine is a fictional machine, so has no specifications. Which
  devices can be changed/added/removed without impact? Are interrupts
  correctly mapped?
- prep firmware (OHW) has support only for IDE drives (no SCSI).
  Booting from IDE has been broken approximatively 3 years ago, and nobody complained.
- OHW is limited on IDE boot to a specific set of OS loaders.
  These operating systems are of the 2004 time frame.
- OHW can use -kernel. Linux kernel freezes a long time after PS/2 mouse
  detection, and then screen becomes garbage. This was already broken in
  QEMU v2.7, 2 years ago, and nobody complained.

On the other side:
- 40p is a real machine, so emulation can be checked against
  hardware specifications
- OpenBIOS has support for SCSI block devices, including 40p LSI adapter
- OpenBIOS can start mostly all Linux kernels (including recent ones)
  and recent operating system (like NetBSD 7.1.2)

Peter Maydell 627fce6178 tests/boot-serial-test: Bump timeout to 6 minutes
On a SPARC host that I'm using as a build test machine, the
boot-serial-test for the SPARC guest machines takes about 65
seconds to execute. This means that it hits the current
60 second timer on these tests. Push the timeout up so
that it doesn't trigger spuriously on slow hosts like this one.

Markus Armbruster f9e986d237 libqtest: Improve error reporting for bad read from QEMU
When read() from the qtest socket or the QMP socket fails or EOFs, we
report "Broken pipe" and exit(1).  This commonly happens when QEMU
crashes.  It also happens when QEMU refuses to run because the test
passed it bad arguments.  Sadly, we neglect to report either.

Improve this by calling abort() instead of exit(1), so kill_qemu()
runs, and reports how QEMU died.  This improves error reporting to
something like

    /x86_64/device/introspect/list: Broken pipe
    tests/libqtest.c:129: kill_qemu() detected QEMU death from signal 6 (Aborted) (dumped core)

Three exit() remain in libqtest.c:

* In qmp_response(), when we can't parse a QMP reply read from the QMP
  socket.  Change to abort() for consistency.

* In qtest_qemu_binary(), when QTEST_QEMU_BINARY isn't in the
  environment.  This can only happen before we start QEMU.  Leave
  alone.

* In qtest_init_without_qmp_handshake(), when the fork()ed child fails
  to execlp().  Leave alone.

exit() elsewhere are unlikely due to QEMU dying on us.  If that should
turn out to be wrong, we can move kill_qemu() from @abrt_hooks to
atexit() or something.

Eric Blake 71a268a5fd tests/libqtest: Improve kill_qemu()
In kill_qemu() we have an assert that checks that the QEMU process
didn't dump core:
            assert(!WCOREDUMP(wstatus));

Unfortunately the WCOREDUMP macro here means the resulting message
is not very easy to comprehend on at least some systems:

ahci-test: tests/libqtest.c:113: kill_qemu: Assertion `!(((__extension__ (((union { __typeof(wstatus) __in; int __i; }) { .__in = (wstatus) }).__i))) & 0x80)' failed.

and it doesn't identify what signal the process took. What's more,
WCOREDUMP is not reliable - in some cases, setrlimit() coupled with
kernel dump settings can result in the flag not being set.  It's
better to log ALL death by signal, instead of caring whether a core
dump was attempted (although once we know a signal happened, also
mentioning if a core dump is present can be helpful).

Furthermore, we are NOT detecting EINTR (while EINTR shouldn't be
happening if we didn't install signal handlers, it's still better
to always be robust).

Finally, even non-signal death with a non-zero status is suspicious,
since qemu's SIGINT handler is supposed to result in exit(0).

Instead of using a raw assert, print the information in an
easier to understand way:

/i386/ahci/sanity: tests/libqtest.c:129: kill_qemu() detected QEMU death from signal 11 (Segmentation fault) (core dumped)

(Of course, the really useful information would be why the QEMU
process dumped core in the first place, but we don't have that
by the time the test program has picked up the exit status.)

13 of 13 C99 library function pairs taking ... or a va_list parameter
are called FOO() and vFOO().  In QEMU, we sometimes call the one
taking a va_list FOOv() instead.  Bad taste.  libqtest.h uses both
spellings.  Normalize it to the standard spelling.

Markus Armbruster 88b988c895 libqtest: Replace qtest_startf() by qtest_initf()
qtest_init() creates a new QTestState, and leaves @global_qtest alone.
qtest_start() additionally assigns it to @global_qtest, but
qtest_startf() additionally assigns NULL to @global_qtest.  This makes
no sense.  Replace it by qtest_initf() that works like qtest_init(),
i.e. leaves @global_qtest alone.

Markus Armbruster c44a56d8ba migration-test: Clean up string interpolation into QMP, part 3
Leaving interpolation into JSON to qmp() is more robust than building
QMP input manually, as explained in the recent commit "tests: Clean up
string interpolation into QMP input (simple cases)".

migration-test.c interpolates strings into JSON in a few places:

* migrate_set_parameter() interpolates string parameter @value as a
  JSON number.  Change it to long long.  This requires changing
  migrate_check_parameter() similarly.

* migrate_set_capability() interpolates string parameter @value as a
  JSON boolean.  Change it to bool.

* deprecated_set_speed() interpolates string parameter @value as a
  JSON number.  Change it to long long.

Bonus: gets rid of non-literal format strings.  A step towards
compile-time format string checking without triggering
-Wformat-nonliteral.

Falls apart if @command contain '%'.  Two ways to disarm this trap:
