When killing the subcommand, it is intended to first send
SIGTERM, then SIGKILL and only report an error if it still
doesn't die after SIGKILL. The 'step' counter was not
being incremented though, so the code never got past the
SIGTERM stage.

Otherwise there is a race where the DEVICE_DELETED event has been sent but
attempts to reuse the ID will fail.
Note that similar races exist for other QemuOpts, which this patch
does not attempt to fix.
For example, if the device is a block device, then unplugging it also
deletes its backend. However, this backend's get deleted in
drive_info_del(), which is only called when properties are
destroyed. Just like device_finalize(), drive_info_del() is called
some time after DEVICE_DELETED is sent. A separate patch series has
been sent to plug this other bug. Character devices also have yet to
be fixed.

Currently the ObjectProperty iterator API works as follows:
ObjectPropertyIterator *iter;
iter = object_property_iter_init(obj);
while ((prop = object_property_iter_next(iter))) {
...
}
object_property_iter_free(iter);
This has the benefit that the ObjectPropertyIterator struct
can be opaque, but has the downside that callers need to
explicitly call a free function. It is also not in keeping
with iterator style used elsewhere in QEMU/GLib2.
This patch changes the API to use stack allocation instead:
ObjectPropertyIterator iter;
object_property_iter_init(&iter, obj);
while ((prop = object_property_iter_next(&iter))) {
...
}

When there are many instances of a given class, registering
properties against the instance is wasteful of resources. The
majority of objects have a statically defined list of possible
properties, so most of the properties are easily registerable
against the class. Only those properties which are conditionally
registered at runtime need be recorded against the klass.
Registering properties against classes also makes it possible
to provide static introspection of QOM - currently introspection
is only possible after creating an instance of a class, which
severely limits its usefulness.
This impl only supports simple scalar properties. It does not
attempt to allow child object / link object properties against
the class. There are ways to support those too, but it would
make this patch more complicated, so it is left as an exercise
for the future.
There is no equivalent to object_property_del() provided, since
classes must be immutable once they are defined.

Similarly to the commit 764eb39d1b6 fixing VNC+SASL+QXL, when starting
QEMU with SPICE but no SASL, and at the same time VNC with SASL, then
spice_server_init() will get called without a previous call to
spice_server_set_sasl_appname(), which will cause cyrus-sasl to
try to use /etc/sasl2/spice.conf (spice-server uses "spice" as its
default appname) rather than the expected /etc/sasl2/qemu.conf.
This commit unconditionally calls spice_server_set_sasl_appname()
before calling spice_server_init() in order to use the correct appname
even if SPICE without SASL was requested on qemu command line.

This pointer should be cleared in vnc_display_close()
otherwise a use-after-free can happen when when using the
old style 'x509' and 'tls' options rather than a persistent
tls-creds -object, by issuing monitor commands to change
the vnc server like so:
Start with: -vnc unix:test.socket,x509,tls
Then use the following monitor command:
change vnc unix:test.socket
After this the pointer is still set but invalid and a crash
can be triggered for instance by issuing the same command a
second time which will try to object_unparent() the same
pointer again.

Even without line editing, this makes -qmp vc more pleasant with the

In SPARC32 the env->cwp and env->psrpil state is part of the PSR
register, and gets migrated as part of that register.
In SPARC64 this state is in separate CWP and PIL registers, but we
were not doing anything to migrate those.
Add the missing fields to the migration vmstate (which is a
migration break, but without these fields migration is completely
broken anyway).
This change means that trying a save/load of a SPARC64 target at
the boot rom prompt now produces a system which at least responds
to keyboard input after the restore.

For inbound migration we really want to be able to set the PSR without
having any side effects, but cpu_put_psr() calls cpu_check_irqs() which
might try to deliver CPU interrupts. Split cpu_put_psr() into the
no-side-effect and side-effect parts.
This includes reordering the cpu_check_irqs() to the end of cpu_put_psr(),
because that function may actually end up calling cpu_interrupt(), which
does not seem like a good thing to happen in the middle of updating the PSR.

Typically a UNIX guest OS will log boot messages to a serial
port in addition to any graphical console. An admin user
may also wish to use the serial port for an interactive
console. A virtualization management system may wish to
collect system boot messages by logging the serial port,
but also wish to allow admins interactive access.
Currently providing such a feature forces the mgmt app
to either provide 2 separate serial ports, one for
logging boot messages and one for interactive console
login, or to proxy all output via a separate service
that can multiplex the two needs onto one serial port.
While both are valid approaches, they each have their
own downsides. The former causes confusion and extra
setup work for VM admins creating disk images. The latter
places an extra burden to re-implement much of the QEMU
chardev backends logic in libvirt or even higher level
mgmt apps and adds extra hops in the data transfer path.
A simpler approach that is satisfactory for many use
cases is to allow the QEMU chardev backends to have a
"logfile" property associated with them.
$QEMU -chardev socket,host=localhost,port=9000,\
server=on,nowait,id-charserial0,\
logfile=/var/log/libvirt/qemu/test-serial0.log
-device isa-serial,chardev=charserial0,id=serial0
This patch introduces a 'ChardevCommon' struct which
is setup as a base for all the ChardevBackend types.
Ideally this would be registered directly as a base
against ChardevBackend, rather than each type, but
the QAPI generator doesn't allow that since the
ChardevBackend is a non-discriminated union. The
ChardevCommon struct provides the optional 'logfile'
parameter, as well as 'logappend' which controls
whether QEMU truncates or appends (default truncate).

Create a coroutine in nbd_client_new, so that nbd_send_negotiate doesn't
need qemu_set_block().
Handlers need to be set temporarily for csock fd in case the coroutine
yields during I/O.
With this, if the other end disappears in the middle of the negotiation,
we don't block the whole event loop.
To make the code clearer, unify all function names that belong to
negotiate, so they are less likely to be misused. This is important
because we rely on negotiation staying in main loop, as commented in
nbd_negotiate_read/write().

This unifies error handling paths of NBDClient allocation:
nbd_client_new will shutdown the socket and call the "close_fn" callback

the normal close.

The qemu-char.c contains two helper methods send_all
and recv_all. These are in fact declared in sockets.h
so ought to have been in util/qemu-sockets.c. For added
fun the impl of recv_all is completely missing on Win32.
Fortunately there is only a single caller of these
methods, the TPM passthrough code, which is only
ever compiled on Linux. With only a single caller
these helpers are not compelling enough to keep so
inline them in the TPM code, avoiding the need to
fix the missing recv_all on Win32.

Fam Zheng noticed that the change in commit 36896bf ("scsi: always call
notifier on async cancellation", 2015-12-16) could cause a leak of
the request; scsi_req_cancel_async now calls scsi_req_ref
multiple times for multiple cancellations, but there is only
one call to scsi_req_cancel_complete.
So revert the patch and instead assert that the problematic case (a call
to scsi_req_cancel_async after the aiocb has been completed) cannot
happen.

When booting the VM with UEFI, UEFI takes ownership of the RTC hardware.
While UEFI can use libfdt to disable the RTC device node in the DTB that
it passes to the OS, it cannot modify AML. Therefore, we won't generate
the RTC ACPI device at all when using UEFI.

gdb won't actually dump these with 'info all-registers' since
it first tries to confirm that it should by checking the VFP
hwcap in the .auxv note. Well, we don't generate an .auxv note.

crash assumes the physical base in the kdump subheader of
makedumpfile formatted dumps is correct. Zero is not correct
for all architectures, so allow it to be changed.

This is necessary for targets that don't have TARGET_PAGE_SIZE ==
real-target-page-size. The target should set the page size to the
correct one, if known, or, if not known, to the maximum page size
it supports.

Only one of three architectures implementing qmp-dump-guest-memory write
qemu notes. And, another architecture (arm/aarch64) is coming, which
won't use them either. Make the common implementation truly common.
