xen-block: Fix removal of backend instance via xenstore
Whenever a Xen block device is detach via xenstore, the image
associated with it remained open by the backend QEMU and an error is
logged:
qemu-system-i386: failed to destroy drive: Node xvdz-qcow2 is in use
This happened since object_unparent() doesn't immediately frees the
object and thus keep a reference to the node we are trying to free.
The reference is hold by the "drive" property and the call
xen_block_drive_destroy() fails.
In order to fix that, we call drain_call_rcu() to run the callback
setup by bus_remove_child() via object_unparent().

4294967295 (byte offset

(which evaluates to
4294967295).
This happens because the code is confused about which of XRa, XRb and
XRc is the output, and which are the inputs. XRa is the output, but
most of the conditions separating out different special cases are
written as if XRc is the output, with the result that we can end up
in the code path that assumes XRa is non-0 even when it is zero.
Fix the erroneous code, bringing it in to line with the structure
used in functions like gen_mxu_S32MAX_S32MIN() and
gen_mxu_Q8MAX_Q8MIN().

net: Pad short frames to minimum size before sending from SLiRP/TAP
The minimum Ethernet frame length is 60 bytes. For short frames with
smaller length like ARP packets (only 42 bytes), on a real world NIC
it can choose either padding its length to the minimum required 60
bytes, or sending it out directly to the wire. Such behavior can be
hardcoded or controled by a register bit. Similarly on the receive
path, NICs can choose either dropping such short frames directly or
handing them over to software to handle.
On the other hand, for the network backends like SLiRP/TAP, they
don't expose a way to control the short frame behavior. As of today
they just send/receive data from/to the other end connected to them,
which means any sized packet is acceptable. So they can send and
receive short frames without any problem. It is observed that ARP
packets sent from SLiRP/TAP are 42 bytes, and SLiRP/TAP just send
these ARP packets to the other end which might be a NIC model that
does not allow short frames to pass through.
To provide better compatibility, for packets sent from QEMU network
backends like SLiRP/TAP, we change to pad short frames before sending
it out to the other end, if the other end does not forbid it via the
nc->do_not_pad flag. This ensures a backend as an Ethernet sender
does not violate the spec. But with this change, the behavior of
dropping short frames from SLiRP/TAP interfaces in the NIC model
cannot be emulated because it always receives a packet that is spec
complaint. The capability of sending short frames from NIC models is
still supported and short frames can still pass through SLiRP/TAP.
This commit should be able to fix the issue as reported with some
NIC models before, that ARP requests get dropped, preventing the
guest from becoming visible on the network. It was workarounded in
these NIC models on the receive path, that when a short frame is
received, it is padded up to 60 bytes.
The following 2 commits seem to be the one to workaround this issue
in e1000 and vmxenet3 before, and should probably be reverted.

monitor: Drop query-qmp-schema 'gen': false hack
QMP commands return their response as a generated QAPI type, which the
monitor core converts to JSON via QObject.
query-qmp-schema's response is the generated introspection data. This
is a QLitObject since commit
7d0f982bfb "qapi: generate a literal
qobject for introspection", v2.12). Before, it was a string. Instead
of converting QLitObject / string -> QObject -> QAPI type
SchemaInfoList -> QObject -> JSON, we take a shortcut: the command is
'gen': false, so it can return the QObject instead of the QAPI type.
Slightly simpler and more efficient.
The next commit will filter the response for output policy, and this
is easier in the SchemaInfoList representation. Drop the shortcut.
This replaces the manual command registration by a generated one. The
manual registration makes the command available before the machine is
built by passing flag QCO_ALLOW_PRECONFIG. To keep it available
there, we need need to add 'allow-preconfig': true to its definition
in the schema.

qemu-options: New -compat to set policy for deprecated interfaces
New option -compat lets you configure what to do when deprecated
interfaces get used. This is intended for testing users of the
management interfaces. It is experimental.
-compat deprecated-input=<input-policy> configures what to do when
deprecated input is received. Input policy can be "accept" (accept
silently), or "reject" (reject the request with an error).
-compat deprecated-output=<out-policy> configures what to do when
deprecated output is sent. Output policy can be "accept" (pass on
unchanged), or "hide" (filter out the deprecated parts).
Default is "accept". Policies other than "accept" are implemented
later in this series.
For now, -compat covers only syntactic aspects of QMP, i.e. stuff
tagged with feature 'deprecated'. We may want to extend it to cover
semantic aspects, CLI, and experimental features.
Note that there is no good way for management application to detect
presence of -compat: it's not visible output of query-qmp-schema or
query-command-line-options. Tolerable, because it's meant for
testing. If running with -compat fails, skip the test.

i386: Make migration fail when Hyper-V reenlightenment was enabled but 'user_tsc_khz' is unset
KVM doesn't fully support Hyper-V reenlightenment notifications on
migration. In particular, it doesn't support emulating TSC frequency
of the source host by trapping all TSC accesses so unless TSC scaling
is supported on the destination host and KVM_SET_TSC_KHZ succeeds, it
is unsafe to proceed with migration.
KVM_SET_TSC_KHZ is called from two sites: kvm_arch_init_vcpu() and
kvm_arch_put_registers(). The later (intentionally) doesn't propagate
errors allowing migrations to succeed even when TSC scaling is not
supported on the destination. This doesn't suit 're-enlightenment'

Emulators are currently using OptsVisitor (via user_creatable_add_opts)

compared to keyval, which is automatic conversion of integers to lists
as well as support for lists as repeated options:
-object memory-backend-ram,id=pc.ram,size=

patch moves the user_creatable_add_opts logic to vl.c since it is
not needed anywhere else, and makes it go through user_creatable_add_qapi.

options in that it reorders options before it processes them. This means
that parsing object options and creating the object happen at two
different points. Split the parsing part into a separate function that
can be reused by the system emulator command line.

hmp: QAPIfy object_add
This switches the HMP command object_add from a QemuOpts-based parser to
user_creatable_add_from_str() which uses a keyval parser and enforces
the QAPI schema.
Apart from being a cleanup, this makes non-scalar properties and help
accessible. In order for help to be printed to the monitor instead of
stdout, the printf() calls in the help functions are changed to
qemu_printf().

As a side effect, fix wrong exit codes in the object parsing error path
of 'qemu-img compare'. This was broken in commit
334c43e2c3 because
&error_fatal exits with an exit code of 1, while it should have been 2.
Document that exit code 0 is also returned when just requested help was

curl: Disconnect sockets from CURLState
When a curl transfer is finished, that does not mean that CURL lets go
of all the sockets it used for it. We therefore must not free a
CURLSocket object before CURL has invoked curl_sock_cb() to tell us to
remove it. Otherwise, we may get a use-after-free, as described in this
bug report: https://bugs.launchpad.net/qemu/+bug/
1916501
(Reproducer from that report:
$ qemu-img convert -f qcow2 -O raw \
https://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img \
out.img
)
(Alternatively, it might seem logical to force-drop all sockets that
have been used for a state when the respective transfer is done, kind of
like it is done now, but including unsetting the AIO handlers.
Unfortunately, doing so makes the driver just hang instead of crashing,
which seems to evidence that CURL still uses those sockets.)
Make the CURLSocket object independent of "its" CURLState by putting all
sockets into a hash table belonging to the BDRVCURLState instead of a
list that belongs to a CURLState. Do not touch any sockets in
curl_clean_state().
Testing, it seems like all sockets are indeed gone by the time the curl
BDS is closed, so it seems like there really was no point in freeing any
socket just because a transfer is done. libcurl does invoke
curl_sock_cb() with CURL_POLL_REMOVE for every socket it has.
