The traditional QMP command handler interface
int qmp_FOO(Monitor *mon, const QDict *params, QObject **ret_data);
doesn't provide for returning an Error object. Instead, the handler
is expected to stash it in the monitor with qerror_report().
When we rebased QMP on top of QAPI, we didn't change this interface.
Instead, commit 776574d introduced "middle mode" as a temporary aid
for converting existing QMP commands to QAPI one by one. More than
three years later, we're still using it.
Middle mode has two effects:
* Instead of the native input marshallers
static void qmp_marshal_input_FOO(QDict *, QObject **, Error **)
it generates input marshallers conforming to the traditional QMP
command handler interface.
* It suppresses generation of code to register them with
qmp_register_command()
This permits giving them internal linkage.
As long as we need qmp-commands.hx, we can't use the registry behind
qmp_register_command(), so the latter has to stay for now.
The former has to go to get rid of qerror_report(). Changing all QMP
commands to fit the QAPI mold in one go was impractical back when we
started, but by now there are just a few stragglers left:
do_qmp_capabilities(), qmp_qom_set(), qmp_qom_get(), qmp_object_add(),
qmp_netdev_add(), do_device_add().
Switch middle mode to generate native input marshallers, and adapt the
stragglers. Simplifies both the monitor code and the stragglers.
Rename do_qmp_capabilities() to qmp_capabilities(), and
do_device_add() to qmp_device_add, because that's how QMP command
handlers are named today.

qerror_report_err() is a transitional interface to help with
converting existing monitor commands to QMP. It should not be used
elsewhere.
The only remaining user in qemu-option.c is qemu_opts_parse(). Is it
used in QMP context? If not, we can simply replace
qerror_report_err() by error_report_err().
The uses in qemu-img.c, qemu-io.c, qemu-nbd.c and under tests/ are
clearly not in QMP context.
The uses in vl.c aren't either, because the only QMP command handlers
there are qmp_query_status() and qmp_query_machines(), and they don't
call it.
Remaining uses:
* drive_def(): Command line -drive and such, HMP drive_add and pci_add
* hmp_chardev_add(): HMP chardev-add
* monitor_parse_command(): HMP core
* tmp_config_parse(): Command line -tpmdev
* net_host_device_add(): HMP host_net_add
* net_client_parse(): Command line -net and -netdev
* qemu_global_option(): Command line -global
* vnc_parse_func(): Command line -display, -vnc, default display, HMP
change, QMP change. Bummer.
* qemu_pci_hot_add_nic(): HMP pci_add
* usb_net_init(): Command line -usbdevice, HMP usb_add
Propagate errors through qemu_opts_parse(). Create a convenience
function qemu_opts_parse_noisily() that passes errors to
error_report_err(). Switch all non-QMP users outside tests to it.
That leaves vnc_parse_func(). Propagate errors through it. Since I'm
touching it anyway, rename it to vnc_parse().

all the target agnostic users really just want the cpu pointer. These
users then need to use the target-specifically defined ENV_GET_CPU to
navigate back up to the CPU from the ENV. Split the API for the two
uses cases to remove all need for ENV_GET_CPU.

The asynchronous monitor command interface goes back to commit 940cc30
(Jan 2010). Added a third case to command execution. The hope back
then according to the commit message was that all commands get
converted to the asynchronous interface, killing off the other two
cases. Didn't happen.
The initial asynchronous commands balloon and info balloon were
converted back to synchronous long ago (commit 96637bc and d72f32),
with commit messages calling the asynchronous interface "not fully
working" and "deprecated". The only other user went away in commit
3b5704b.
New code generally uses synchronous commands and asynchronous events.
What exactly is still "not fully working" with asynchronous commands?
Well, here's a bug that defeats actual asynchronous use pretty
reliably: the reply's ID is wrong (and has always been wrong) unless
you use the command synchronously! To reproduce, we need an
asynchronous command, so we have to go back before commit 3b5704b.
Run QEMU with spice:
$ qemu-system-x86_64 -nodefaults -S -spice port=5900,disable-ticketing -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 94, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}}
Connect a spice client in another terminal:
$ remote-viewer spice://localhost:5900
Set up a migration destination dummy in a third terminal:
$ socat TCP-LISTEN:12345 STDIO
Now paste the following into the QMP monitor:
{ "execute": "qmp_capabilities", "id": "i0" }
{ "execute": "client_migrate_info", "id": "i1", "arguments": { "protocol": "spice", "hostname": "localhost", "port": 12345 } }
{ "execute": "query-kvm", "id": "i2" }
Produces two replies immediately, one to qmp_capabilities, and one to
query-kvm:
{"return": {}, "id": "i0"}
{"return": {"enabled": false, "present": true}, "id": "i2"}
Both are correct. Two lines of debug output from libspice-server not
shown.
Now EOF socat's standard input to make it close the connection. This
makes the asynchronous client_migrate_info complete. It replies:
{"return": {}}
Bug: "id": "i1" is missing. Two lines of debug output from
libspice-server not shown. Cherry on top: storage for the missing ID
is leaked.
Get rid of this stuff before somebody hurts himself with it.

before using it, otherwise this may cause unexpected memory access.

Live migration with spice works like this today:
(1) client_migrate_info monitor cmd
(2) spice server notifies client, client connects to target host.
(3) qemu waits until spice client connect is finished.
(4) send over vmstate (i.e. main part of live migration).
(5) spice handover to target host.
(3) is implemented by making client_migrate_info a async monitor
command. This is the only async monitor command we have.
The original reason to implement this dance was that qemu did not accept
new tcp connections while the incoming migration was running, so (2) and
(4) could not be done in parallel. That issue was fixed long ago though.
Qemu version 1.3.0 (released Dec 2012) and newer happily accept tcp
connects while the incoming migration runs.
Time to drop step (3). This patch does exactly that, by making the
monitor command synchronous and removing the code needed to handle the
async monitor command in ui/spice-core.c

Switch all the uses of ld/st*_phys to address_space_ld/st*,

2ed1ebcf6 "timer: replace time() with QEMU_CLOCK_HOST" broke compile
when configured with --enable-profiler. Turned out the profiler has been
broken for a while.
This does s/qemu_time/tcg_time/ as the profiler only works in a TCG mode.
This also fixes the compile error.
This changes profile_getclock() to return nanoseconds rather than
CPU ticks as the "profile" HMP command prints seconds and there is no
platform-independent way to get ticks-per-second rate.
Since TCG is quite slow and get_clock() returns nanoseconds (fine
enough), this should not affect precision much.
This removes unused qemu_time_start and tlb_flush_time.

monitor_read_bdrv_key_start() does several things:
1. If no key is needed, call completion_cb() and succeed
2. If we're in QMP context, call qerror_report_err() and fail
3. Start reading the key in the monitor.
This is two things too many. Inline 1. and 2. into its callers
monitor_read_block_device_key() and usb_msd_realize_storage().
Since monitor_read_block_device_key() only ever runs in HMP context,

The monitor code for doing a memory_dump() was using ld*_raw() to do

for this purpose are ld*_p(), which take a host pointer, rather than
ld*_raw(), which take an integer representing a guest address and
are somewhat meaningless in softmmu configurations. Nobody noticed
because for softmmu the _raw functions are the same as ldl_p but
with some extra casts thrown in. Switch to using the correct functions

The commits:

- 66e56b13 (qdev: add qdev_build_hotpluggable_device_list helper)
cause a QEMU crash when trying to use HMP device_del auto-completion.
It can be easily reproduced by:
<qemu-bin> -enable-kvm ~/images/fedora.qcow2 -monitor stdio -device virtio-net-pci,id=vnet
(qemu) device_del
/home/mapfelba/git/upstream/qemu/hw/core/qdev.c:941:qdev_build_hotpluggable_device_list: Object 0x7f6ce04e4fe0 is not an instance of type device
Aborted (core dumped)
The root cause is qdev_build_hotpluggable_device_list going recursively over
all peripherals and their children assuming all are devices. It doesn't work
since PCI devices have at least on child which is a memory region (bus master).
Solved by observing that all devices appear as direct children of
/machine/peripheral container. No need of going recursively
over all the children.

Commit cdaa86a54 ("Add G_IO_HUP handler for socket chardev") exposed a bug in
the way the HMP monitor handles its command buffer. When a client closes the
connection to the monitor, tcp_chr_read() will detect the G_IO_HUP condition
and call tcp_chr_disconnect() to close the server-side connection too. Due to
the fact that monitor reads 1 byte at a time (for each tcp_chr_read()), the
monitor readline state / buffers might contain junk (i.e. a half-finished
command). Thus, without calling readline_restart() on mon->rs in
CHR_EVENT_OPEN, future HMP commands will fail.

On FreeBSD polling a master pty while the other end is not connected
with G_IO_OUT only results in an endless wait. This is different from
the Linux behaviour, that returns immediately. In order to demonstrate
this, I have the following example code:
http://xenbits.xen.org/people/royger/test_poll.c
When executed on Linux:
$ ./test_poll
In callback
On FreeBSD instead, the callback never gets called:
$ ./test_poll
So, in order to workaround this, poll the source with G_IO_HUP (which
makes the code behave the same way on both Linux and FreeBSD).

The monitor is now hooked on the new event mechanism, so that later
patches can convert event callers one by one. Most code are copied from
old monitor_protocol_* functions with some modification.
Note that two build time warnings will be raised after this patch. One is
caused by no caller of monitor_qapi_event_throttle(), the other one is
caused by QAPI_EVENT_MAX = 0. They will be fixed automatically after
full event conversion later.

The monitor support for disassembling instructions does not honor the MSR[LE]
bit for PowerPC processors.
This change enhances the monitor_disas() routine by supporting a flag bit
for Little Endian mode. Bit 16 is used since that bit was used in the
analagous guest disassembly routine target_disas().
Also, to be consistent with target_disas(), the disassembler bfd_mach field
can be passed in the flags argument.

Two new functions are added; the first one checks a given range in the

The second one should be used immediately before writing to the image
file as it calls the first function and, upon collision, marks the
image as corrupt and makes the BDS unusable, thereby preventing
further access.
Both functions take a bitmask argument specifying the structures which
should be checked for overlaps, making it possible to also check
metadata writes against colliding with other structures.

In order to support sub command in auto completion, a reentrant function
is needed, so monitor_find_completion() is split into two parts. The
first part does parsing of user input which need to be done only once,
the second part does the auto completion job according to the parsing
result, which contains the necessary code to support sub command and
works as the reentrant function. The global "info_cmds" is still used
in second part, which will be replaced by sub command code later.

The old code in help_cmd() uses global 'info_cmds' and treats it as a
special case. Actually 'info_cmds' is a sub command group of 'mon_cmds',
in order to avoid direct use of it, help_cmd() needs to change its work
mechanism to support sub command and not treat it as a special case
any more.
To support sub command, help_cmd() will first parse the input and then call
help_cmd_dump(), which works as a reentrant function. When it meets a sub
command, it simply enters the function again. Since help dumping needs to
know whole input to printf full help message include prefix, for example,
"help info block" need to printf prefix "info", so help_cmd_dump() takes all
args from input and extra parameter arg_index to identify the progress.
Another function help_cmd_dump_one() is introduced to printf the prefix
and command's help message.
Now help supports sub command, so later if another sub command group is
added in any depth, help will automatically work for it. Still "help info
block" will show error since command parser reject additional parameter,
which can be improved later. "log" is still treated as a special case.

Since this function will be used by help_cmd() later, so improve
it to make it more generic and easier to use. free_cmdline_args()
is added too as paired function to free the result.
One change of this function is that, when the valid args in input
exceed the limit of MAX_ARGS, it fails now, instead of return with
MAX_ARGS of parsed args in old code. This should not impact much
since it is rare that user input many args in monitor's "help" and
auto complete scenario.

When monitor_flush() is invoked repeatedly outside the monitor_unblocked()
callback, for example from tlb_info() -> ... -> print_pte(), several
watches may be added for the same event.
This is no problem per se because the extra monitor_unblocked() callbacks
are harmless if mon->outbuf is empty, the watches will be removed
gradually. However a big number of watches can grow "gpollfds" without
limit in glib_pollfds_fill(), triggering a -1/EINVAL condition in
g_poll().
Keep at most one such watch, by following the pattern observable in eg.
commits c874ea97 and c3d6b96e. The change has no effect when
monitor_unblocked() calls monitor_flush() (when the watch can either be
removed or renewed 1-for-1), but non-callback contexts won't create an
additional watch when the monitor already has one.

Currently macvtap based macvlan device is working in promiscuous
mode, we want to implement mac-programming over macvtap through
Libvirt for better performance.
Design:
QEMU notifies Libvirt when rx-filter config is changed in guest,
then Libvirt query the rx-filter information by a monitor command,
and sync the change to macvtap device. Related rx-filter config
of the nic contains main mac, rx-mode items and vlan table.
This patch adds a QMP event to notify management of rx-filter change,
and adds a monitor command for management to query rx-filter
information.
Test:
If we repeatedly add/remove vlan, and change macaddr of vlan
interfaces in guest by a loop script.
Result:
The events will flood the QMP client(management), management takes
too much resource to process the events.
Event_throttle API (set rate to 1 ms) can avoid the events to flood
QMP client, but it could cause an unexpected delay (~1ms), guests
guests normally expect rx-filter updates immediately.
So we use a flag for each nic to avoid events flooding, the event
is emitted once until the query command is executed. The flag
implementation could not introduce unexpected delay.
There maybe exist an uncontrollable delay if we let Libvirt do the
real change, guests normally expect rx-filter updates immediately.
But it's another separate issue, we can investigate it when the
work in Libvirt side is done.
Michael S. Tsirkin: tweaked to enable events on start
Michael S. Tsirkin: fixed not to crash when no id
Michael S. Tsirkin: fold in patch:

The TPM subsystem does not have a full front-end/back-end separation.
The sole available backend, tpm_passthrough, depends on the data
structures of the sole available frontend, tpm_tis.
However, we can at least try to split the user interface (tpm.c) from the
implementation (hw/tpm). The patches makes tpm.c not include tpm_int.h,
which is shared between tpm_tis.c and tpm_passthrough.c; instead it
moves more stuff to tpm_backend.h.

The Memory chardev driver was added because, as the Monitor's output
buffer was static, we needed a way to accumulate the output of an
HMP commmand when ran by human-monitor-command.
However, the Monitor's output buffer is now dynamic, so it's possible
for the human-monitor-command to use it instead of the Memory chardev
driver.
This commit does that change, but there are two important
observations about it:
1. We need a way to signal to the Monitor that it shouldn't call
chardev functions when flushing its output. This is done
by adding a new flag to the Monitor object called skip_flush
(which is set to true by qmp_human_monitor_command())
2. The current code has buffered semantics: QMP clients will
only see a command's output if it flushes its output with
a new-line character. This commit changes this to unbuffered,
which means that QMP clients will see a command's output
whenever the command prints anything.
I don't think this will matter in practice though, as I believe
all HMP commands print the new-line character anyway.

Commit f628926bb4 changed monitor_flush()
to retry on qemu_chr_fe_write() errors. However, the Monitor's output
buffer can keep growing while the retry is not issued and this can
cause the buffer to overflow.
To reproduce this issue, just start qemu and type on the Monitor:
(qemu) ?
This will cause an assertion to trig.
To fix this problem this commit makes the Monitor buffer dynamic,
which means that it can grow as much as needed.

The PowerPC 620 was the very first 64-bit PowerPC implementation, but
hardly anyone ever actually used the chips. qemu notionally supports the
620, but since we don't actually have code to implement the segment table,
the support is broken (quite likely in other ways too).
This patch, therefore, removes all remaining pieces of 620 support, to
stop it cluttering up the platforms we actually care about. This includes
removing support for the ASR register, used only on segment table based
machines.

This patch adds support for TPM command line options.
The command line options supported here are
./qemu-... -tpmdev passthrough,path=<path to TPM device>,id=<id>
-device tpm-tis,tpmdev=<id>,id=<other id>
and
./qemu-... -tpmdev help
where the latter works similar to -soundhw help and shows a list of
available TPM backends (for example 'passthrough').
Using the type parameter, the backend is chosen, i.e., 'passthrough' for the
passthrough driver. The interpretation of the other parameters along
with determining whether enough parameters were provided is pushed into
the backend driver, which needs to implement the interface function
'create' and return a TPMDriverOpts structure if the VM can be started or
'NULL' if not enough or bad parameters were provided.
Monitor support for 'info tpm' has been added. It for example prints the
following:
(qemu) info tpm
TPM devices:
tpm0: model=tpm-tis
\ tpm0: type=passthrough,path=/dev/tpm0,cancel-path=/sys/devices/pnp0/00:09/cancel

The setjmp() function doesn't specify whether signal masks are saved and
restored; on Linux they are not, but on BSD (including MacOSX) they are.
We want to have consistent behaviour across platforms, so we should
always use "don't save/restore signal mask" (this is also generally
going to be faster). This also works around a bug in MacOSX where the
signal-restoration on longjmp() affects the signal mask for a completely
different thread, not just the mask for the thread which did the longjmp.
The most visible effect of this was that ctrl-C was ignored on MacOSX
because the CPU thread did a longjmp which resulted in its signal mask
being applied to every thread, so that all threads had SIGINT and SIGTERM
blocked.
The POSIX-sanctioned portable way to do a jump without affecting signal
masks is to siglongjmp() to a sigjmp_buf which was created by calling
sigsetjmp() with a zero savemask parameter, so change all uses of
setjmp()/longjmp() accordingly. [Technically POSIX allows sigsetjmp(buf, 0)
to save the signal mask; however the following siglongjmp() must not
restore the signal mask, so the pair can be effectively considered as
"sigjmp/longjmp which don't touch the mask".]
For Windows we provide a trivial sigsetjmp/siglongjmp in terms of
setjmp/longjmp -- this is OK because no user will ever pass a non-zero
savemask.
The setjmp() uses in tests/tcg/test-i386.c and tests/tcg/linux-test.c
are left untouched because these are self-contained singlethreaded
test programs intended to be run under QEMU's Linux emulation, so they
have neither the portability nor the multithreading issues to deal with.

The following behaviors are possible:
'report': The behavior is the same as in 1.1. An I/O error,
respectively during a read or a write, will complete the job immediately
with an error code.
'ignore': An I/O error, respectively during a read or a write, will be
ignored. For streaming, the job will complete with an error and the
backing file will be left in place. For mirroring, the sector will be
marked again as dirty and re-examined later.
'stop': The job will be paused and the job iostatus will be set to
failed or nospace, while the VM will keep running. This can only be
specified if the block device has rerror=stop and werror=stop or enospc.
'enospc': Behaves as 'stop' for ENOSPC errors, 'report' for others.
In all cases, even for 'report', the I/O error is reported as a QMP
event BLOCK_JOB_ERROR, with the same arguments as BLOCK_IO_ERROR.
It is possible that while stopping the VM a BLOCK_IO_ERROR event will be
reported and will clobber the event from BLOCK_JOB_ERROR, or vice versa.
This is not really avoidable since stopping the VM completes all pending
I/O requests. In fact, it is already possible now that a series of
BLOCK_IO_ERROR events are reported with rerror=stop, because vm_stop

Convert 'sendkey' to use QAPI.
QAPI passes key's index of mapping table to qmp_send_key(),
not keycode. So we use help functions to convert key/code to
index of key_defs, and 'index' will be converted to 'keycode'
inside qmp_send_key().
For qmp, QAPI would check invalid key and raise error.
For hmp, invalid key is checked in hmp_send_key().

When migrating, libvirt queries the migration status, and upon migration
completions, it closes the migration src. On the other hand, when
migration is completed, spice transfers data from the src to destination
via the client. This data is required for keeping the spice session
after migration, without suffering from data loss and inconsistencies.
In order to allow this data transfer, we add QEVENT for signaling
libvirt that spice migration has completed, and libvirt needs to wait
for this event before quitting the src process.

At some point in the past, the OPEN event was changed to be issued from a

This patch adds support that enables passing of file descriptors
to the QEMU monitor where they will be stored in specified file
descriptor sets.
A file descriptor set can be used by a client like libvirt to
store file descriptors for the same file. This allows the
client to open a file with different access modes (O_RDWR,
O_WRONLY, O_RDONLY) and add/remove the passed fds to/from an fd
set as needed. This will allow QEMU to (in a later patch in this
series) "open" and "reopen" the same file by dup()ing the fd in
the fd set that corresponds to the file, where the fd has the
matching access mode flag that QEMU requests.
The new QMP commands are:
add-fd: Add a file descriptor to an fd set
remove-fd: Remove a file descriptor from an fd set
query-fdsets: Return information describing all fd sets
Note: These commands are not compatible with the existing getfd
and closefd QMP commands.

There are three possible ways of having this event, as described here:
http://lists.gnu.org/archive/html/qemu-devel/2012-07/msg02307.html
I've decided to add a new event and make it indepedent of SHUTDOWN.
This means that the SHUTDOWN event will eventually follow the
SUSPEND_DISK event.
I've choosen this way because of two reasons:
1. Having an indepedent event makes it possible to query for its
existence by using query-events
2. In the future, we may allow the user to change what QEMU should
do as a result of the guest entering S4. So it's a good idea to

IMPORTANT: this BREAKS QMP's compatibility for the error response.
This commit changes QMP's wire protocol to make use of the simpler
error format introduced by previous commits.
There are two important (and mostly incompatible) changes:
1. Almost all error classes have been replaced by GenericError. The
only classes that are still supported for compatibility with
libvirt are: CommandNotFound, DeviceNotActive, KVMMissingCap,
DeviceNotFound and MigrationExpected
2. The 'data' field of the error dictionary is gone
As an example, an error response like:
{ "error": { "class": "DeviceNotRemovable",
"data": { "device": "virtio0" },
"desc": "Device 'virtio0' is not removable" } }
Will now be emitted as:
{ "error": { "class": "GenericError",
"desc": "Device 'virtio0' is not removable" } }

"This command is only available from the human monitor. It's not very
useful because it historically hasn't been able to pretty-print events
or show them in the right order (we use a ringbuffer but it prints
them out from index 0).
Therefore, I don't think we're under any obligation to keep this

think this is a sign that no one has used it. I'd be okay with a

Allow certain event types to be rate limited to avoid flooding
monitor clients. The monitor_protocol_event() method is changed
such that instead of immediately emitting the event to Monitor
instances, it will call a new monitor_protocol_event_queue()
method.
This will check to see if the rate limit for the event has been
exceeded, and if so schedule a timer to wakeup at the end of the
rate limit period. If further events arrive before the timer fires,
the previously queued event will be discarded in favour of the new
event. The event will eventually be emitted when the timer fires.
This logic is applied to RTC_CHANGE, BALLOON_CHANGE & WATCHDOG
events, since the data associated with these events is stateless

After setting a balloon target value, applications have to
continually poll 'query-balloon' to determine whether the
guest has reacted to this request. The virtio-balloon backend
knows exactly when the guest has reacted though, and thus it
is possible to emit a JSON event to tell the mgmt application
whenever the guest balloon changes.
This introduces a new 'qemu_balloon_changed()' API which is
to be called by balloon driver backends, whenever they have
a change in balloon value. This takes the 'actual' balloon
value, as would be found in the BalloonInfo struct.
The qemu_balloon_change API emits a JSON monitor event which
looks like:
{"timestamp": {"seconds": 1337162462, "microseconds": 814521},
"event": "BALLOON_CHANGE", "data": {"actual": 944766976}}

negative before the conversion, which will lead to a flawed conversion.
For example, this:

Just "works", but the value passed by the balloon command will be
something else.
