The QMP monitor code has two helper methods object_add
and qmp_object_del that are called from several places
in the code (QMP, HMP and main emulator startup).
The HMP and main emulator startup code also share
further logic that extracts the qom-type & id
values from a qdict.
We soon need to use this logic from qemu-img, qemu-io
and qemu-nbd too, but don't want those to depend on
the monitor, nor do we want to duplicate the code.
To avoid this, move some code out of qmp.c and hmp.c
adding new methods to qom/object_interfaces.c
- user_creatable_add - takes a QDict holding a full
object definition & instantiates it
- user_creatable_add_type - takes an ID, type name,
and QDict holding object properties & instantiates
it
- user_creatable_add_opts - takes a QemuOpts holding
a full object definition & instantiates it
- user_creatable_add_opts_foreach - variant on
user_creatable_add_opts which can be directly used
in conjunction with qemu_opts_foreach.
- user_creatable_del - takes an ID and deletes the
corresponding object
The existing code is updated to use these new methods.

This patch implements proposal from Paolo to handle system reset when

"After a reset, main_loop_should_exit should actually transition

visit_start_struct() and visit_type_enum() had a 'kind' argument
that was usually set to either the stringized version of the
corresponding qapi type name, or to NULL (although some clients
didn't even get that right). But nothing ever used the argument.
It's even hard to argue that it would be useful in a debugger,
as a stack backtrace also tells which type is being visited.
Therefore, drop the 'kind' argument as dead.

[Harmless rebase mistake cleaned up]
Signed-off-by: Markus Armbruster <armbru@redhat.com>
JSON uses "name":value, but many of our visitor interfaces were
called with visit_type_FOO(v, &value, name, errp). This can be
a bit confusing to have to mentally swap the parameter order to
match JSON order. It's particularly bad for visit_start_struct(),
where the 'name' parameter is smack in the middle of the
otherwise-related group of 'obj, kind, size' parameters! It's
time to do a global swap of the parameter ordering, so that the
'name' parameter is always immediately after the Visitor argument.
Additional reason in favor of the swap: the existing include/qjson.h
prefers listing 'name' first in json_prop_*(), and I have plans to
unify that file with the qapi visitors; listing 'name' first in
qapi will minimize churn to the (admittedly few) qjson.h clients.
Later patches will then fix docs, object.h, visitor-impl.h, and
those clients to match.
Done by first patching scripts/qapi*.py by hand to make generated
files do what I want, then by running the following Coccinelle
script to affect the rest of the code base:
$ spatch --sp-file script `git grep -l '\bvisit_' -- '**/*.[ch]'`
I then had to apply some touchups (Coccinelle insisted on TAB
indentation in visitor.h, and botched the signature of
visit_type_enum() by rewriting 'const char *const strings[]' to
the syntactically invalid 'const char*const[] strings'). The
movement of parameters is sufficient to provoke compiler errors
if any callers were missed.

Guarantee that visit_end_struct() is called if
visit_start_struct() succeeded. This matches the behavior of
most other uses of visitors, and is a step towards the possibility
of a future patch that adds and enforces some tighter semantics to
the visitor interface (namely, cleanup of the visitor would no
longer have to mop up as many leftovers from an aborted partial
visit).
The change to code here matches the flow of hmp.c:hmp_object_add();
a later patch will then further simplify the cleanup logic of both
places by refactoring visit_end_struct() to not require a second
local error object.

The qapi visitor contract allows us to visit a virtual structure,
where we don't have any corresponding qapi struct. Most such uses
pass NULL for @obj; but these two callers were passing a dummy
pointer, which then gets allocated to heap memory but then
immediately freed without use. Clean this up to suppress unwanted
allocation, like we do elsewhere.

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))) {
...
}

vhost-user-test prints a warning. A test should not need to run on
hugetlbfs, let's silence the warning under qtest. The
condition can't check on qtest_enabled() since vhost-user-test actually
doesn't use qtest accel. However, qtest_driver() can be used, if
qtest_init() is called early enough. For that reason, move chardev and
qtest initialization early.

Stop directly accessing the Object::properties field data
structure and instead use the formal object property iterator
APIs. This insulates the code from future data structure
changes in the Object struct.

The HOST_PAGE_ALIGN macros don't work until the page size variables
have been set up; later in postcopy I use those macros in the RAM
code, and it can be triggered using -object.
Fix this by initialising page_size_init() earlier - it's currently
initialised inside the accelerators, move it up into vl.c.

This patch introduces command line options for enabling recording or replaying
virtual machine behavior. These options are added to icount command line
parameter. They include 'rr' which switches between record and replay
and 'rrfile' for specifying the filename for replay log.

This makes the purpose of the function clearer: it is not about the
version of QEMU that's running, but the version string exposed in the

Straightforward replacement, except for qemu_kill_report(), which
printed a common part of its error message first, then the applicable
special part. Print each complete message with a single
error_report() instead.
Multi-line messages were replaced by error_report() followed by
error_printf().
The following changes were made to the error messages:
* The "invalid date format" message was reworded to better fit
the new error_report()+error_printf() pattern.
* On the remaining messages, only the trailing newlines, "qemu:" and
"error:" message prefixes were removed.

This filter is to buffer/release packets. Can be used when using
MicroCheckpointing or other Remus like VM FT solutions.
You can also use it to crudely simulate network delay. Doesn't
actually delay individual packets, but batches them together, which is
a delay of sorts.
Usage:
-netdev tap,id=bn0
-object filter-buffer,id=f0,netdev=bn0,queue=rx,interval=1000
NOTE:
Interval is in microseconds, it can't be omitted currently, and can't be 0.
