hw/arm/sysbus-fdt: Fix assertion in copy_properties_from_host()
When copy_properties_from_host() ignores the error for an optional
property, it frees the error, but fails to reset it.
Hence if two or more optional properties are missing, an assertion is
triggered:
util/error.c:57: error_setv: Assertion `*errp == NULL' failed.
Fis this by resetting err to NULL after ignoring the error.

tests: fix TLS handshake failure with TLS 1.3
When gnutls negotiates TLS 1.3 instead of 1.2, the order of messages
sent by the handshake changes. This exposed a logic bug in the test
suite which caused us to wait for the server to see handshake
completion, but not wait for the client to see completion. The result
was the client didn't receive the certificate for verification and the
test failed.
This is exposed in Fedora 29 rawhide which has just enabled TLS 1.3 in
its GNUTLS builds.

set and instead asserting on a return value. This means that when an

making failures hard to diagnose. Changing these tests to pass in
&error_abort will make unexpected failures print messages to stderr.

tests: don't silence error reporting for all tests
The test-vmstate test is a bit chatty because it triggers various

instead of accepting 'Error **errp' parameters. To silence this test the
stubs for error_vprintf() were changed to send errors via
g_test_message() instead of stderr:

Message-Id: <

Unfortunately this change has global impact across the entire test suite
and means that when tests fail for unexpected reasons, the message is
not displayed on stderr. eg when using &error_abort in a call the test
merely prints
Unexpected error in qcrypto_tls_session_check_certificate() at crypto/tlssession.c:280:
and the actual error message is hidden, making it impossible to diagnose
the failure. This is especially problematic in CI or build systems where
it isn't possible to easily pass the --debug-log flag to tests and
re-run with the test log visible.
This change makes the previous big hammer much more nuanced, providing a
flag in the stub error_vprintf() that can used on a per-test basis to
silence the errors. Only the test-vmstate silences errors initially.

target/arm: Escalate to correct HardFault when AIRCR.BFHFNMINS is set
When we escalate a v8M exception to HardFault, if AIRCR.BFHFNMINNS is
set then we need to decide whether it should become a secure HardFault
or a nonsecure HardFault. We should always escalate to the same
target security state as the original exception. The current code
tries to test this using the 'secure' bool, which is not right because
that flag indicates whether the target security state only for
banked exceptions; the effect was that we were incorrectly escalating
always-secure exceptions like SecureFault to a nonsecure HardFault.

hw/intc/exynos4210_gic: Turn instance_init into realize function
The instance_init function of the "exynos4210.gic" device creates a
new "arm_gic" device and immediately realizes it with qdev_init_nofail().
This will leave a lot of object in the QOM tree during introspection of
the "exynos4210.gic" device, e.g. reproducible by starting QEMU like this:
qemu-system-aarch64 -M none -nodefaults -nographic -monitor stdio
And then by running "info qom-tree" at the HMP monitor, followed by
"device_add exynos4210.gic,help" and finally checking "info qom-tree"
again.
Also note that qdev_init_nofail() can exit QEMU in case of errors - and
this must never happen during an instance_init function, otherwise QEMU
could terminate unexpectedly during introspection of a device.
Since most of the code that follows the qdev_init_nofail() depends on
the realized "gicbusdev", the easiest solution to the problem is to
turn the whole instance_init function into a realize function instead.

target/arm: Correctly handle overlapping small MPU regions
To correctly handle small (less than TARGET_PAGE_SIZE) MPU regions,
we must correctly handle the case where the address being looked
up hits in an MPU region that is not small but the address is
in the same page as a small region. For instance if MPU region
1 covers an entire page from 0x2000 to 0x2400 and MPU region
2 is small and covers only 0x2200 to 0x2280, then for an access
to 0x2000 we must not return a result covering the full page
even though we hit the page-sized region 1. Otherwise we will
then cache that result in the TLB and accesses that should
hit region 2 will incorrectly find the region 1 information.
Check for the case where we miss an MPU region but it is still
within the same page, and in that case narrow the size we will
pass to tlb_set_page_with_attrs() for whatever the final
outcome is of the MPU lookup.

monitor: Fix unsafe sharing of @cur_mon among threads
@cur_mon is null unless the main thread is running monitor code, either
HMP code within monitor_read(), or QMP code within
monitor_qmp_dispatch().
Use of @cur_mon outside the main thread is therefore unsafe.
Most of its uses are in monitor command handlers. These run in the main
thread.
However, there are also uses hiding elsewhere, such as in
error_vprintf(), and thus error_report(), making these functions unsafe
outside the main thread. No such unsafe uses are known at this time.
Regardless, this is an unnecessary trap. It's an ancient trap, though.
More recently, commit
cf869d53172 "qmp: support out-of-band (oob)
execution" spiced things up: the monitor I/O thread assigns to @cur_mon
when executing commands out-of-band. Having two threads save, set and
restore @cur_mon without synchronization is definitely unsafe. We can
end up with @cur_mon null while the main thread runs monitor code, or
non-null while it runs non-monitor code.
We could fix this by making the I/O thread not mess with @cur_mon, but
that would leave the trap armed and ready.
Instead, make @cur_mon thread-local. It's now reliably null unless the
thread is running monitor code.

linux-user: fix ELF load alignment error
When we try to use some targets on ppc64, it can happen the target
doesn't support the host page size to align ELF load sections and
fails with:
ELF load command alignment not page-aligned
Since commit
a70daba3771 ("linux-user: Tell guest about big host
page sizes") the host page size is used to align ELF sections, but
this doesn't work if the alignment required by the load section is
smaller than the host one. For these cases, we continue to use the
TARGET_PAGE_SIZE instead of the host one.
I have tested this change on ppc64, and it fixes qemu linux-user for:
s390x, m68k, i386, arm, aarch64, hppa
and I have tested it doesn't break the following targets:
x86_64, mips64el, sh4
mips and mipsel abort, but I think for another reason.

throttle-groups: fix hang when group member leaves
Throttle groups consist of members sharing one throttling state
(including bps/iops limits). Round-robin scheduling is used to ensure
fairness. If a group member already has a timer pending then other
groups members do not schedule their own timers. The next group member
will have its turn when the existing timer expires.
A hang may occur when a group member leaves while it had a timer
scheduled. Although the code carefully removes the group member from
the round-robin list, it does not schedule the next member. Therefore
remaining members continue to wait for the removed member's timer to
expire.
This patch schedules the next request if a timer is pending.
Unfortunately the actual bug is a race condition that I've been unable
to capture in a test case.
Sometimes drive2 hangs when drive1 is removed from the throttling group:

s390x/cpumodel: fix segmentation fault when baselining models
Usually, when baselining two CPU models, whereby one of them has base
CPU features disabled (e.g. z14-base,msa=off), we fallback to an older
model that did not have these features in the base model. We always try to
create a "sane" CPU model (as far as possible), and one part of it is that
removing base features is no good and to be avoided.
Now, if we disable base features that were part of a z900, we're out of
luck. We won't find a CPU model and QEMU will segfault. This is a
scenario that should never happen in real life, but it can be used to
crash QEMU.
So let's properly report an error if we baseline e.g.:
{ "execute": "query-cpu-model-baseline",
"arguments" : { "modela": { "name": "z14-base", "props": {"esan3" : false}},
"modelb": { "name": "z14"}} }

the first loop to store the parse module names in a list, and the second
loop can now use these names. This avoids having to pass NULL to the
get_opt_value() method which means it can safely assume a non-NULL param.

i386: fix regression parsing multiboot initrd modules
The logic for parsing the multiboot initrd modules was messed up in

opts: don't silently truncate long option values
Causing the length to be undercounter, and the number of modules over
counted. It also passes NULL to get_opt_value() which was not robust
at accepting a NULL value.

hw/arm/xlnx-zynqmp: Fix crash when introspecting the "xlnx, zynqmp" device
QEMU currently crashes when e.g. doing something like this:
echo "{'execute':'qmp_capabilities'} {'execute':'device-list-properties'," \
"'arguments':{'typename':'xlnx,zynqmp'}}" \
"{'execute': 'human-monitor-command', " \
"'arguments': {'command-line': 'info qtree'}}" \

Use the new object_initialize_child() and sysbus_init_child_obj()
functions to get the refernce counting of the child objects right, so
that they are properly cleaned up when the parent gets destroyed.

hw/display/xlnx_dp: Move problematic code from instance_init to realize
aux_create_slave() calls qdev_init_nofail() which in turn "realizes"
the corresponding object. This is unlike qdev_create(), and it is wrong
because qdev_init_nofail() must not be called from an instance_init
function. Move qdev_init_nofail() and the subsequent aux_map_slave into
the caller's realize function.
There are two more bugs that needs to be fixed here, too, where the
objects are created but not added as children. Therefore when
you call object_unparent on them, nothing happens.
In particular dpcd and edid give you an infinite loop in bus_unparent,
because device_unparent is not called and does not remove them from
the list of devices on the bus.
