David Hildenbrand 9181fb7043 hostmem: Wire up RAM_NORESERVE via "reserve" property
Let's provide a way to control the use of RAM_NORESERVE via memory
backends using the "reserve" property which defaults to true (old
behavior).

Only Linux currently supports clearing the flag (and support is checked at
runtime, depending on the setting of "/proc/sys/vm/overcommit_memory").
Windows and other POSIX systems will bail out with "reserve=false".

The target use case is virtio-mem, which dynamically exposes memory
inside a large, sparse memory area to the VM. This essentially allows
avoiding to set "/proc/sys/vm/overcommit_memory == 0") when using
virtio-mem and also supporting hugetlbfs in the future.

As really only Linux implements RAM_NORESERVE right now, let's expose
the property only with CONFIG_LINUX. Setting the property to "false"
will then only fail in corner cases -- for example on very old kernels
or when memory overcommit was completely disabled by the admin.

Philippe Mathieu-Daudé caff255a54 tpm: Return QMP error when TPM is disabled in build
When the management layer queries a binary built using --disable-tpm
for TPM devices, it gets confused by getting empty responses:

  { "execute": "query-tpm" }
  {
      "return": [
      ]
  }
  { "execute": "query-tpm-types" }
  {
      "return": [
      ]
  }
  { "execute": "query-tpm-models" }
  {
      "return": [
      ]
  }

To make it clearer by returning an error:
- Make the TPM QAPI schema conditional
  All of tpm.json is now 'if': 'defined(CONFIG_TPM)'.
- Adapt the HMP command
- Remove stubs which became unnecessary

The management layer now gets a 'CommandNotFound' error:

  { "execute": "query-tpm" }
  {
      "error": {
          "class": "CommandNotFound",
          "desc": "The command query-tpm has not been found"
      }
  }

Brijesh Singh 3ea1a80243 target/i386/sev: add support to query the attestation report
The SEV FW >= 0.23 added a new command that can be used to query the
attestation report containing the SHA-256 digest of the guest memory
and VMSA encrypted with the LAUNCH_UPDATE and sign it with the PEK.

Note, we already have a command (LAUNCH_MEASURE) that can be used to
query the SHA-256 digest of the guest memory encrypted through the
LAUNCH_UPDATE. The main difference between previous and this command
is that the report is signed with the PEK and unlike the LAUNCH_MEASURE
command the ATTESATION_REPORT command can be called while the guest
is running.

Add a QMP interface "query-sev-attestation-report" that can be used
to get the report encoded in base64.

Gerd Hoffmann de74a22cc8 ui/vdagent: core infrastructure
The vdagent protocol allows the guest agent (spice-vdagent) and the
spice client exchange messages to implement features which require
guest cooperation, for example clipboard support.

This is a qemu implementation of the spice client side.  This allows
the spice guest agent talk to qemu directly when not using the spice
protocol.

usage: qemu \
  -chardev qemu-vdagent,id=vdagent \
  -device virtserialport,chardev=vdagent,name=com.redhat.spice.0

This patch adds just the protocol basics: initial handshake and
capability negotiation.  The following patches will add actual
functionality and also add fields to the initially empty
ChardevVDAgent qapi struct.

Thomas Huth 438c61e086 qapi/qom.json: Do not use CONFIG_VIRTIO_CRYPTO in common code
The ObjectType enum and ObjectOptions are included from qapi-types-qom.h
into common code. We should not use target-specific config switches like
CONFIG_VIRTIO_CRYPTO here, since this is not defined in common code and
thus the enum will look differently between common and target specific
code. For this case, it's hopefully enough to check for CONFIG_VHOST_CRYPTO
only (which is a host specific config switch, i.e. it's the same on all
targets).

Paolo Bonzini a061a71e0d qapi: qom: do not use target-specific conditionals
ObjectType and ObjectOptions are defined in a target-independent file,
therefore they do not have access to target-specific configuration
symbols such as CONFIG_PSERIES or CONFIG_SEV.  For this reason,
pef-guest and sev-guest are currently omitted when compiling the
generated QAPI files.  In addition, this causes ObjectType to have
different definitions depending on the file that is including
qapi-types-qom.h (currently this is not causing any issues, but it
is wrong).

Define the two enum entries and the SevGuestProperties type
unconditionally to avoid the issue.  We do not expect to have
many target-dependent user-creatable classes, so it is not
particularly problematic.

Markus Armbruster 624fa80c8c 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.

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.

Kevin Wolf 9151e59a8b qapi/qom: QAPIfy object-add
This converts object-add from 'gen': false to the ObjectOptions QAPI
type. As an immediate benefit, clients can now use QAPI schema
introspection for user creatable QOM objects.

It is also the first step towards making the QAPI schema the only
external interface for the creation of user creatable objects. Once all
other places (HMP and command lines of the system emulator and all
tools) go through QAPI, too, some object implementations can be
simplified because some checks (e.g. that mandatory options are set) are
already performed by QAPI, and in another step, QOM boilerplate code
could be generated from the schema.

This adds a QAPI schema for the properties of the input-* objects.

ui.json cannot be included in qom.json because the storage daemon can't
use it, so move GrabToggleKeys to common.json.

This adds a QAPI schema for the properties of the objects implementing
the confidential-guest-support interface.

pef-guest and s390x-pv-guest don't have any properties, so they only
need to be added to the ObjectType enum without adding a new branch to
ObjectOptions.
