handle_qmp_command() reports certain errors right away. This is wrong
when OOB is enabled, because the errors can "jump the queue" then, as
the previous commit demonstrates.
To fix, we need to delay errors until dispatch. Do that for semantic
errors, mostly by reverting ill-advised parts of commit cf869d53172
"qmp: support out-of-band (oob) execution". Bonus: doesn't run
qmp_dispatch_check_obj() twice, once in handle_qmp_command(), and
again in do_qmp_dispatch(). That's also due to commit cf869d53172.
The next commit will fix queue jumping for syntax errors.

Commit cf869d53172 "qmp: support out-of-band (oob) execution" added a
general mechanism for command-independent arguments just for an
out-of-band flag:
The "control" key is introduced to store this extra flag. "control"
field is used to store arguments that are shared by all the commands,
rather than command specific arguments. Let "run-oob" be the first.
However, it failed to reject unknown members of "control". For
instance, in QMP command
{"execute": "query-name", "id": 42, "control": {"crap": true}}
"crap" gets silently ignored.
Instead of fixing this, revert the general "control" mechanism
(because YAGNI), and do it the way I initially proposed, with key
"exec-oob". Simpler code, simpler interface.
An out-of-band command
{"execute": "migrate-pause", "id": 42, "control": {"run-oob": true}}
becomes
{"exec-oob": "migrate-pause", "id": 42}

[Commit message typo fixed]

Commit cf869d53172 "qmp: support out-of-band (oob) execution"
accidentally made qemu-ga accept and ignore "control". Fix that.
Out-of-band execution in a monitor that doesn't support it now fails
with
{"error": {"class": "GenericError", "desc": "QMP input member 'control' is unexpected"}}
instead of
{"error": {"class": "GenericError", "desc": "Please enable out-of-band first for the session during capabilities negotiation"}}
The old description is suboptimal when out-of-band cannot not be
enabled, or the command doesn't support out-of-band execution.
The new description is a bit unspecific, but it'll do.

Commit cf869d53172 "qmp: support out-of-band (oob) execution" changed
how we check "id":
Note that in the patch I exported qmp_dispatch_check_obj() to be
used to check the request earlier, and at the same time allowed
"id" field to be there since actually we always allow that.
The part after "and" is ill-advised: it makes qemu-ga accept and
ignore "id". Revert.

tests/qmp-test tests an out-of-band command overtaking a slow in-band
command. To do that, it needs:
1. An in-band command that *reliably* takes long enough to be
overtaken.
2. An out-of-band command to do the overtaking.
3. To avoid delays, a way to make the in-band command complete quickly
after it was overtaken.
To satisfy these needs, commit 469638f9cb3 provides the rather
peculiar oob-capable QMP command x-oob-test:
* With "lock": true, it waits for a global semaphore.
* With "lock": false, it signals the global semaphore.
To satisfy 1., the test runs x-oob-test in-band with "lock": true.
To satisfy 2. and 3., it runs x-oob-test out-of-band with "lock": false.
Note that waiting for a semaphore violates the rules for oob-capable
commands. Running x-oob-test with "lock": true hangs the monitor
until you run x-oob-test with "lock": false on another monitor (which
you might not have set up).
Having an externally visible QMP command that may hang the monitor is
not nice. Let's apply a little more ingenuity to the problem. Idea:
have an existing command block on reading a FIFO special file, unblock
it by opening the FIFO for writing.
For 1., use
{"execute": "blockdev-add", "id": ID1,
"arguments": {
"driver": "blkdebug", "node-name": ID1, "config": FIFO,
"image": { "driver": "null-co"}}}
where ID1 is an arbitrary string, and FIFO is the name of the FIFO.
For 2., use
{"execute": "migrate-pause", "id": ID2, "control": {"run-oob": true}}
where ID2 is a different arbitrary string. Since there's no migration
to pause, the command will fail, but that's fine; instant failure is
still a test of out-of-band responses overtaking in-band commands.
For 3., open FIFO for writing.
Drop QMP command x-oob-test.

Events are broadcast to all monitors. If another monitor's client has
a command with the same ID in flight, the event will incorrectly claim
that command was dropped. This must be fixed before out-of-band

Add #if defined(CONFIG_VNC) in generated code, and adjust the
qmp/hmp code accordingly.
query-qmp-schema no longer reports the command/events etc as
available when disabled at compile.
Commands made conditional:
* query-vnc, query-vnc-servers, change-vnc-password
Before the patch, the commands for !CONFIG_VNC are stubs that fail
like this:
{"error": {"class": "GenericError",
"desc": "The feature 'vnc' is not enabled"}}
Afterwards, they fail like this:
{"error": {"class": "CommandNotFound",
"desc": "The command FOO has not been found"}}
I call that an improvement, because it lets clients distinguish
between command unavailable (class CommandNotFound) and command failed
(class GenericError).
Events made conditional:
* VNC_CONNECTED, VNC_INITIALIZED, VNC_DISCONNECTED
HMP change:
* info vnc
Will return "unknown command: 'info vnc'" when VNC is compiled
out (same as error for spice when --disable-spice)
Occurrences of VNC (case insensitive) in the schema that aren't
covered by this change:
* add_client
Command has other uses, including "socket bases character devices".
These are unconditional as far as I can tell.
* set_password, expire_password
In theory, these commands could be used for managing any service's
password. In practice, they're used for VNC and SPICE services.
They're documented for "remote display session" / "remote display
server".
The service is selected by argument @protocol. The code special-cases
protocol-specific argument checking, then calls a protocol-specific
function to do the work. If it fails, the command fails with "Could
not set password". It does when the service isn't compiled in (it's a
stub then).
We could make these commands conditional on the conjunction of all
services [currently: defined(CONFIG_VNC) || defined(CONFIG_SPICE)],
but I doubt it's worthwhile.
* change
Command has other uses, namely changing media.
This patch inlines a stub; no functional change.

In order to test that the NBD server is properly advertising
dirty bitmaps, we need a bare minimum client that can request
and read the context. Since feature freeze for 3.0 is imminent,
this is the smallest workable patch, which replaces the qemu
block status report with the results of the NBD server's dirty
bitmap (making it very easy to use 'qemu-img map --output=json'
to learn where the dirty portions are). Note that the NBD
protocol defines a dirty section with the same bit but opposite
sense that normal "base:allocation" uses to report an allocated
section; so in qemu-img map output, "data":true corresponds to
clean, "data":false corresponds to dirty.
A more complete solution that allows dirty bitmaps to be queried
at the same time as normal block status will be required before
this addition can lose the x- prefix. Until then, the fact that
this replaces normal status with dirty status means actions
like 'qemu-img convert' will likely misbehave due to treating
dirty regions of the file as if they are unallocated.
The next patch adds an iotest to exercise this new code.

This patch adds Windows crashdumping feature. Now QEMU can produce ELF-dump
containing Windows crashdump header, which can help to convert to a valid
WinDbg-understandable crashdump file, or immediately create such file.
The crashdump will be obtained by joining physical memory dump and 8K header
exposed through vmcoreinfo/fw_cfg device by guest driver at BSOD time. Option
'-w' was added to dump-guest-memory command. At the moment, only x64
configuration is supported.

This patch implements active synchronous mirroring. In active mode, the
passive mechanism will still be in place and is used to copy all
initially dirty clusters off the source disk; but every write request
will write data both to the source and the target disk, so the source
cannot be dirtied faster than data is mirrored to the target. Also,
once the block job has converged (BLOCK_JOB_READY sent), source and
target are guaranteed to stay in sync (unless an error occurs).
Active mode is completely optional and currently disabled at runtime. A
later patch will add a way for users to enable it.

Legacy -drive supports "password-secret" parameter that isn't
available with -blockdev / blockdev-add. That's because we backed out
our first try to provide it there due to interface design doubts, in
commit 577d8c9a811, v2.9.0.
This is the second try. It brings back the parameter, except it's
named "key-secret" now.
Let's review our reasons for backing out the first try, as stated in
the commit message:
* BlockdevOptionsRbd member @password-secret isn't actually a
password, it's a key generated by Ceph.
Addressed by the rename.
* We're not sure where member @password-secret belongs (see the
previous commit).
See previous commit.
* How @password-secret interacts with settings from a configuration
file specified with @conf is undocumented.
Not actually true, the documentation for @conf says "Values in the
configuration file will be overridden by options specified via QAPI",
and we've tested this.

Parameter auth-client-required lets you configure authentication
methods. We tried to provide that in v2.9.0, but backed out due to
interface design doubts (commit 464444fcc16).
This commit is similar to what we backed out, but simpler: we use a
list of enumeration values instead of a list of objects with a member
of enumeration type.
Let's review our reasons for backing out the first try, as stated in
the commit message:
* The implementation uses deprecated rados_conf_set() key
"auth_supported". No biggie.
Fixed: we use "auth-client-required".
* The implementation makes -drive silently ignore invalid parameters
"auth" and "auth-supported.*.X" where X isn't "auth". Fixable (in
fact I'm going to fix similar bugs around parameter server), so
again no biggie.
That fix is commit 2836284db60. This commit doesn't bring the bugs
back.
* BlockdevOptionsRbd member @password-secret applies only to
authentication method cephx. Should it be a variant member of
RbdAuthMethod?
We've had time to ponder, and we decided to stick to the way Ceph
configuration works: the key configured separately, and silently
ignored if the authentication method doesn't use it.
* BlockdevOptionsRbd member @user could apply to both methods cephx
and none, but I'm not sure it's actually used with none. If it
isn't, should it be a variant member of RbdAuthMethod?
Likewise.
* The client offers a *set* of authentication methods, not a list.
Should the methods be optional members of BlockdevOptionsRbd instead
of members of list @auth-supported? The latter begs the question
what multiple entries for the same method mean. Trivial question
now that RbdAuthMethod contains nothing but @type, but less so when
RbdAuthMethod acquires other members, such the ones discussed above.
Again, we decided to stick to the way Ceph configuration works, except
we make auth-client-required a list of enumeration values instead of a
string containing keywords separated by delimiters.
* How BlockdevOptionsRbd member @auth-supported interacts with
settings from a configuration file specified with @conf is
undocumented. I suspect it's untested, too.
Not actually true, the documentation for @conf says "Values in the
configuration file will be overridden by options specified via QAPI",
and we've tested this.

Activating the block devices causes the locks to be taken on
the backing file. If we're running with -S and the destination libvirt
hasn't started the destination with 'cont', it's expecting the locks are
still untaken.
Don't activate the block devices if we're not going to autostart the VM;
'cont' already will do that anyway. This change is tied to the new
migration capability 'late-block-activate' that defaults to off, keeping
the old behaviour by default.

The recently introduced qom-list-properties QMP command raised
a question what properties it (and its cousin - device-list-properties)
can possibly print - only those defined by DeviceClass::props
or dynamically created in TypeInfo::instance_init() so properties created
elsewhere won't show up and this behaviour might confuse the user.
For example, PIIX4 does that from piix4_pm_realize() via
piix4_pm_add_propeties():
object_property_add_uint8_ptr(OBJECT(s), ACPI_PM_PROP_ACPI_ENABLE_CMD,
&acpi_enable_cmd, NULL);
This adds a note to the command descriptions about the limitation.

This option allows pausing QEMU in the new RUN_STATE_PRECONFIG state,
allowing the configuration of QEMU from QMP before the machine jumps
into board initialization code of machine_run_board_init()
The intent is to allow management to query machine state and additionally
configure it using previous query results within one QEMU instance
(i.e. eliminate the need to start QEMU twice, 1st to query board specific
parameters and 2nd for actual VM start using query results for
additional parameters).
The new option complements -S option and could be used with or without
it. The difference is that -S pauses QEMU when the machine is completely
initialized with all devices wired up and ready to execute guest code
(QEMU needs only to unpause VCPUs to let guest execute its code),
while the "preconfig" option pauses QEMU early before board specific init
callback (machine_run_board_init) is executed and allows the configuration
of machine parameters which will be used by board init code.
When early introspection/configuration is done, command 'exit-preconfig'
should be used to exit RUN_STATE_PRECONFIG and transition to the next
requested state (i.e. if -S is used then QEMU will pause the second
time when board/device initialization is completed or start guest
execution if -S isn't provided on CLI)
PS:
Initially 'preconfig' is planned to be used for configuring numa
topology depending on board specified possible cpus layout.
