88be7b4be4 block: Fix bdrv_next() memory leak
The bdrv_next() users all leaked the BdrvNextIterator after completing
the iteration. Simply changing bdrv_next() to free the iterator before
returning NULL at the end of list doesn't work because some callers exit
the loop before looking at all BDSes.

This patch moves the BdrvNextIterator from the heap to the stack of
the caller and switches to a bdrv_first()/bdrv_next() interface for
initialising the iterator.

ae50a7702c arm: qmp: add query-gic-capabilities interface
This patch add "query-gic-capabilities" but does not implement it. The
command is ARM-only. The command will return a list of GICCapability
structs that describes all GIC versions that current QEMU and system
support.

Libvirt is possibly the first consumer of this new command.

Before this patch, a libvirt user can successfully configure all kinds
of GIC devices for ARM guests, no matter whether current QEMU/kernel
supports them. If the specified GIC version/type is not supported, the
user will get an ambiguous "QEMU boot failure" error when trying to start
the VM. This is not user-friendly.

With this patch, libvirt should be able to query which type (and which
version) of GIC device is supported. Using this information, libvirt
can warn the user during configuration of guests when specified GIC
device type is not supported. Or better, we can just list those versions
that we support, and filter out the unsupported ones.

For example, if we got the query result:

{"return": [{"emulated": false, "version": 3, "kernel": true},
            {"emulated": true, "version": 2, "kernel": false}]}

then it means that we support emulated GIC version 2 using:

  qemu-system-aarch64 -M virt,accel=tcg,gic-version=2 ...

or KVM-accelerated GIC version 3 using:

  qemu-system-aarch64 -M virt,accel=kvm,gic-version=3 ...

If we specify other explicit GIC versions rather than the above, QEMU
will not be able to boot.

The community is working on a more generic way to query these kinds of
information about valid values of machine properties. However, due to
the importance of supporting this specific use case, weecided to first
implement this ad-hoc one; then when the generic method is ready, we
can move on to that one smoothly.

73bcb24d93 Replaced get_tick_per_sec() by NANOSECONDS_PER_SECOND
This patch replaces get_ticks_per_sec() calls with the macro
NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec()
is then removed.  This replacement improves the readability and
understandability of code.

For example,

    timer_mod(fdctrl->result_timer,
	      qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50));

NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns
matches the unit of the expression on the right side of the plus.

in a child of a Quorum device. This event is emitted at a maximum rate

193227f9e5 error: Use error_report_err() instead of monitor_printf()
Both error_report_err() and monitor_printf() print to the same
destination when monitor_printf() is used correctly, i.e. within an
HMP monitor.  Elsewhere, monitor_printf() does nothing, while
error_report_err() reports to stderr.

Most changed functions are HMP command handlers.  These should only
run within an HMP monitor.  The one exception is bdrv_password_cb(),
which should also only run within an HMP monitor.

Four command handlers prefix the error message with the command name:
balloon, migrate_set_capability, migrate_set_parameter, migrate.
Pointless, drop.

Unlike monitor_printf(), error_report_err() uses the error whole
instead of just its message obtained with error_get_pretty().  This
avoids suppressing its hint (see commit 50b7b00).  Example:

    (qemu) device_add ivshmem,id=666
    Parameter 'id' expects an identifier
    Identifiers consist of letters, digits, '-', '.', '_', starting with a letter.
    Try "help device_add" for more information

The "Identifiers consist of..." line is new with this patch.

d20a580bc0 qapi: Change munging of CamelCase enum values
When munging enum values, the fact that we were passing the entire
prefix + value through camel_to_upper() meant that enum values
spelled with CamelCase could be turned into CAMEL_CASE.  However,
this provides a potential collision (both OneTwo and One-Two would
munge into ONE_TWO) for enum types, when the same two names are
valid side-by-side as QAPI member names.  By changing the generation
of enum constants to always be prefix + '_' + c_name(value,
False).upper(), and ensuring that there are no case collisions (in
the next patches), we no longer have to worry about names that
would be distinct as QAPI members but collide as variant tag names,
without having to think about what munging the heuristics in
camel_to_upper() will actually perform on an enum value.

Making the change will affect enums that did not follow coding
conventions, using 'CamelCase' rather than desired 'lower-case'.

Thankfully, there are only two culprits: InputButton and ErrorClass.
We already tweaked ErrorClass to make it an alias of QapiErrorClass,
where only the alias needs changing rather than the whole tree.  So
the bulk of this change is modifying INPUT_BUTTON_WHEEL_UP to the
new INPUT_BUTTON_WHEELUP (and likewise for WHEELDOWN).  That part
of this commit may later need reverting if we rename the enum
constants from 'WheelUp' to 'wheel-up' as part of moving
x-input-send-event to a stable interface; but at least we have
documentation bread crumbs in place to remind us (commit 513e7cd),
and it matches the fact that SDL constants are also spelled
SDL_BUTTON_WHEELUP.

f22a28b898 qapi: Add alias for ErrorClass
The qapi enum ErrorClass is unusual that it uses 'CamelCase' names,
contrary to our documented convention of preferring 'lower-case'.
However, this enum is entrenched in the API; we cannot change
what strings QMP outputs.  Meanwhile, we want to simplify how
c_enum_const() is used to generate enum constants, by moving away
from the heuristics of camel_to_upper() to a more straightforward
c_name(N).upper() - but doing so will rename all of the ErrorClass
constants and cause churn to all client files, where the new names
are aesthetically less pleasing (ERROR_CLASS_DEVICENOTFOUND looks
like we can't make up our minds on whether to break between words).

So as always in computer science, solve the problem by some more
indirection: rename the qapi type to QapiErrorClass, and add a
new enum ErrorClass in error.h whose members are aliases of the
qapi type, but with the spelling expected elsewhere in the tree.
Then, when c_enum_const() changes the munging, we only have to
adjust the one alias spot.

7fb1cf1606 qapi: Don't let implicit enum MAX member collide
Now that we guarantee the user doesn't have any enum values
beginning with a single underscore, we can use that for our
own purposes.  Renaming ENUM_MAX to ENUM__MAX makes it obvious
that the sentinel is generated.

This patch was mostly generated by applying a temporary patch:

|diff --git a/scripts/qapi.py b/scripts/qapi.py
|index e6d014b..b862ec9 100644
|--- a/scripts/qapi.py
|+++ b/scripts/qapi.py
|@@ -1570,6 +1570,7 @@ const char *const %(c_name)s_lookup[] = {

|     ret += mcgen('''
|     [%(max_index)s] = NULL,
|+// %(max_index)s
| };
| ''',
|                max_index=max_index)

then running:

$ cat qapi-{types,event}.c tests/test-qapi-types.c |
    sed -n 's,^// \(.*\)MAX,s|\1MAX|\1_MAX|g,p' > list
$ git grep -l _MAX | xargs sed -i -f list

The only things not generated are the changes in scripts/qapi.py.

Rejecting enum members named 'MAX' is now useless, and will be dropped
in the next patch.

0a9516c2d6 monitor/target-ppc: Define target_get_monitor_def
At the moment get_monitor_def() returns only registers from statically
defined monitor_defs array. However there is a lot of BOOK3S SPRs
which are not in the list and cannot be printed from the monitor.

This adds a new target platform hook - target_get_monitor_def().
The hook is called if a register was not found in the static
array returned by the target_monitor_defs() hook.

The hook is only defined for POWERPC, it returns registered
SPRs and fails on unregistered ones providing the user with information
on what is actually supported on the running CPU. The register value is
saved as uint64_t as it is the biggest supported register size;
target_ulong cannot be used because of the stub - it is in a "common"
code and cannot include "cpu.h", etc; this is also why the hook prototype
is redefined in the stub instead of being included from some header.

This replaces static descriptors for GPRs, FPRs, SRs with a helper which
looks for a value in a corresponding array in the CPUPPCState.
The immediate effect is that all 32 SRs can be printed now (instead of 16);
later this can be reused for VSX or TM registers.

This replaces callbacks for MSR and XER with static descriptors in
monitor_defs as they are stored in CPUPPCState.

While we are here, this adds "cr" as a synonym of "ccr".

7de0be6573 monitor: Throttle event VSERPORT_CHANGE separately by "id"
VSERPORT_CHANGE is emitted when the guest opens or closes a
virtio-serial port.  The event's member "id" identifies the port.

When several events arrive quickly, throttling drops all but the last
of them.  Because of that, a QMP client must assume that *any* port
may have changed state when it receives a VSERPORT_CHANGE event and
throttling may have happened.

Make the event more useful by throttling it for each port separately.

39a1815816 qapi: New QMP command query-qmp-schema for QMP introspection
qapi/introspect.json defines the introspection schema.  It's designed
for QMP introspection, but should do for similar uses, such as QGA.

The introspection schema does not reflect all the rules and
restrictions that apply to QAPI schemata.  A valid QAPI schema has an
introspection value conforming to the introspection schema, but the
converse is not true.

Introspection lowers away a number of schema details, and makes
implicit things explicit:

* The built-in types are declared with their JSON type.

  All integer types are mapped to 'int', because how many bits we use
  internally is an implementation detail.  It could be pressed into
  external interface service as very approximate range information,
  but that's a bad idea.  If we need range information, we better do
  it properly.

* Implicit type definitions are made explicit, and given
  auto-generated names:

  - Array types, named by appending "List" to the name of their
    element type, like in generated C.

  - The enumeration types implicitly defined by simple union types,
    named by appending "Kind" to the name of their simple union type,
    like in generated C.

  - Types that don't occur in generated C.  Their names start with ':'
    so they don't clash with the user's names.

* All type references are by name.

* The struct and union types are generalized into an object type.

* Base types are flattened.

* Commands take a single argument and return a single result.

  Dictionary argument or list result is an implicit type definition.

  The empty object type is used when a command takes no arguments or
  produces no results.

  The argument is always of object type, but the introspection schema
  doesn't reflect that.

  The 'gen': false directive is omitted as implementation detail.

  The 'success-response' directive is omitted as well for now, even
  though it's not an implementation detail, because it's not used by
  QMP.

* Events carry a single data value.

  Implicit type definition and empty object type use, just like for
  commands.

  The value is of object type, but the introspection schema doesn't
  reflect that.

* Types not used by commands or events are omitted.

  Indirect use counts as use.

* Optional members have a default, which can only be null right now

  Instead of a mandatory "optional" flag, we have an optional default.
  No default means mandatory, default null means optional without
  default value.  Non-null is available for optional with default
  (possible future extension).

* Clients should *not* look up types by name, because type names are
  not ABI.  Look up the command or event you're interested in, then
  follow the references.

  TODO Should we hide the type names to eliminate the temptation?

New generator scripts/qapi-introspect.py computes an introspection
value for its input, and generates a C variable holding it.

It can generate awfully long lines.  Marked TODO.

A new test-qmp-input-visitor test case feeds its result for both
tests/qapi-schema/qapi-schema-test.json and qapi-schema.json to a
QmpInputVisitor to verify it actually conforms to the schema.

New QMP command query-qmp-schema takes its return value from that
variable.  Its reply is some 85KiBytes for me right now.

If this turns out to be too much, we have a couple of options:

* We can use shorter names in the JSON.  Not the QMP style.

* Optionally return the sub-schema for commands and events given as
  arguments.

  Right now qmp_query_schema() sends the string literal computed by
  qmp-introspect.py.  To compute sub-schema at run time, we'd have to
  duplicate parts of qapi-introspect.py in C.  Unattractive.

* Let clients cache the output of query-qmp-schema.

  It changes only on QEMU upgrades, i.e. rarely.  Provide a command
  query-qmp-schema-hash.  Clients can have a cache indexed by hash,
  and re-query the schema only when they don't have it cached.  Even
  simpler: put the hash in the QMP greeting.

485febc6d1 qmp: Wean off qerror_report()
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.

70b9433109 QemuOpts: Wean off qerror_report_err()
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().

Add QMP/HMP support for rocker devices.  This is mostly for debugging purposes
to see inside the device's tables and port configurations.  Some examples:

779cec4d20 monitor: Fix QMP ABI breakage around "id"
Commit 65207c5 accidentally dropped a line of code we need along with
a comment that became wrong then.  This made QMP reject "id":

    {"execute": "system_reset", "id": "1"}
    {"error": {"class": "GenericError", "desc": "QMP input object member 'id' is unexpected"}}

Put the lost line right back, so QMP again accepts and returns "id",
as promised by the ABI:

    {"execute": "system_reset", "id": "1"}
    {"return": {}, "id": "1"}

318660f84a monitor: Use traditional command interface for HMP device_add
All QMP commands use the "new" handler interface (mhandler.cmd_new).
Most HMP commands still use the traditional interface (mhandler.cmd),
but a few use the "new" one.  Complicates handle_user_command() for no
gain, so I'm converting these to the traditional interface.

For device_add, that's easy: just wrap the obvious hmp_device_add()
around do_device_add().

monitor_user_noop() is now unused, drop it.

65207c59d9 monitor: Drop broken, unused asynchronous command interface
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.

bcfa4d6014 monitor: check return value of qemu_find_net_clients_except()
qemu_find_net_clients_except() may return a value which is greater
than the size of array we provided. So we should check this value
before using it, otherwise this may cause unexpected memory access.

This patch fixes the net related command completion when we have a
virtio-net nic with more than 255 queues.

3b5704b2f8 monitor: Make client_migrate_info synchronous
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

42874d3a8c Switch non-CPU callers from ld/st*_phys to address_space_ld/st*
Switch all the uses of ld/st*_phys to address_space_ld/st*,
except for those cases where the address space is the CPU's
(ie cs->as). This was done with the following script which
generates a Coccinelle patch.

A few over-80-columns lines in the result were rewrapped by
hand where Coccinelle failed to do the wrapping automatically,
as well as one location where it didn't put a line-continuation
'\' when wrapping lines on a change made to a match inside
a macro definition.

2d5a8346a4 qmp: Give saner messages related to qmp_capabilities misuse
Pretending that QMP doesn't understand a command merely because
we are not in the right mode doesn't help first-time users figure
out what to do to correct things.  Although the documentation for
QMP calls out capabilities negotiation, we should also make it
clear in our error messages what we were expecting.  With this
patch, I now get the following transcript:

89d5cbddee profiler: Reenable built-in profiler
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.

9b14e0efcc monitor usb: Inline monitor_read_bdrv_key_start()'s first part
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,
drop 2. there.

The next commit will clean up the result in usb_msd_realize_storage().

1677f4c66c monitor: Clean up around monitor_handle_fd_param()
monitor_handle_fd_param() is a wrapper around
monitor_handle_fd_param2() that feeds errors to qerror_report_err()
instead of returning them.  qerror_report_err() is inappropriate in
many contexts.  monitor_handle_fd_param() looks simpler than
monitor_handle_fd_param2(), which tempts use.  Remove the temptation:
drop the wrapper and open-code the (trivial) error handling instead.

Replace the open-coded qerror_report_err() by error_report_err() in
places that already use error_report().  Turns out that's everywhere.

While there, rename monitor_handle_fd_param2() to monitor_fd_param().

The monitor code for doing a memory_dump() was using ld*_raw() to do
target-CPU accesses out of a local buf[] array. The correct functions
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
instead.

4cae4d5aca hmp: fix regression of HMP device_del auto-completion
The commits:
 - 6a1fa9f5 (monitor: add del completion for peripheral device)
 - 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.

7797a73947 hmp: Remove "info pcmcia"
This command lists PCMCIA sockets and cards.  Only a few ARM boards
have sockets (akita, borzoi, connex, mainstone, spitz, terrier, tosa,
verdex, z2), the only card is the DSCM-1xxxx Hitachi Microdrive (qdev
"microdrive"), and it is only inserted during machine init, if ever.
So this command doesn't really tell anybody anything new so far.

Moreover, pcmcia_socket_unregister() has a use-after-free bug, flagged
by Coverity.  Has never been used, because there has never been code
to eject a PCMCIA card.

Not worth fixing & converting to QMP.  Remove it.

e5554e2015 monitor: Reset HMP mon->rs in CHR_EVENT_OPEN
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.

e02bc6de30 serial: poll the serial console with G_IO_HUP
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).

f2ae8abf1f mc146818rtc: add rtc-reset-reinjection QMP command
It is necessary to reset RTC interrupt reinjection backlog if
guest time is synchronized via a different mechanism, such as
QGA's guest-set-time command.

Failing to do so causes both corrections to be applied (summed),
resulting in an incorrect guest time.

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.

1c38f84373 monitor: QEMU Monitor Instruction Disassembly Incorrect for PowerPC LE Mode
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.

c60bf3391b readline: decouple readline from the monitor
Make the readline.c functionality reusable.  Instead of calling
monitor_printf() and monitor_flush() directly, invoke function pointers
provided by the user.

This way readline.c does not know about Monitor and other users will be
able to make use of readline.c.

Note that there is already an "opaque" argument to the ReadLineFunc
callback.  Consistently call it "readline_opaque" from now on to
distinguish from the ReadLinePrintfFunc/ReadLineFlushFunc "opaque"
argument.

I also dropped the printf macro trickery since it's now highly unlikely
that anyone modifying readline.c would call printf(3) directly.  We no
longer need this protection.

a40f1c2add qcow2: Metadata overlap checks
Two new functions are added; the first one checks a given range in the
image file for overlaps with metadata (main header, L1 tables, L2
tables, refcount table and blocks).

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.

c35b640033 monitor: refine monitor_find_completion()
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.

66855495fb monitor: support sub command in help
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.

dcc70cdf09 monitor: refine parse_cmdline()
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.

293d2a0014 monitor: maintain at most one G_IO_OUT watch
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.

b1be42803b net: add support of mac-programming over macvtap in QEMU side
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:
   "additional fixes for mac-programming feature"
Amos Kong: always notify QMP client if mactable is changed

bdee56f546 tpm: reorganize headers and split hardware part
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.

48c043d0d1 hmp: human-monitor-command: stop using the Memory chardev driver
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.

e1f2641b59 Monitor: Make output buffer dynamic
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.

9baea4a303 target-ppc: Remove vestigial PowerPC 620 support
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.

d1a0cf738d Support for TPM command line options
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

6ab7e5465a Replace all setjmp()/longjmp() with sigsetjmp()/siglongjmp()
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.
