365d7f3c7a ui/cocoa.m: remove open dialog code
Removes the open dialog code that runs when no arguments are supplied with QEMU.
Not everyone needs a hard drive or cdrom to boot their target. A user might only
need to use their target's bios to do work. With that said, this patch removes
the unneeded open dialog code.

3b178b7130 ui/cocoa.m: prevent stuck key situation
When the user puts QEMU in the background while holding
down a key, QEMU will not receive the keyup event when
the user lets go of the key. When the user goes back to
QEMU, QEMU will think the key is still down causing
stuck key symptoms. This patch fixes this problem by
releasing all down keys when QEMU goes into the
background.

This patch prevents the user from accidentally quitting QEMU by pushing
Command-Q or by pushing the close button on the main window. When
the user does one of these two things, a dialog box appears verifying

b2af43cc37 spice: surface switch fast path requires same format too.
Commit "555e72f spice: rework mirror allocation, add no-resize fast path"
adds a fast path for surface switches which does't go through the full
primary surface destroy and re-recreation in case the new surface is
identical to the old one (page-flip).  It checks the size only though,
but the format must be identical too.  This patch adds the format check.

Commit "0002a51 ui/spice: Support shared surface for most pixman
formats" increases the chance to actually trigger this.

3e305e4a47 ui: convert VNC server to use QCryptoTLSSession
Switch VNC server over to using the QCryptoTLSSession object
for the TLS session. This removes the direct use of gnutls
from the VNC server code. It also removes most knowledge
about TLS certificate handling from the VNC server code.
This has the nice effect that all the CONFIG_VNC_TLS
conditionals go away and the user gets an actual error
message when requesting TLS instead of it being silently
ignored.

With this change, the existing configuration options for
enabling TLS with -vnc are deprecated.

Old syntax for anon-DH credentials:

  -vnc hostname:0,tls

New syntax:

  -object tls-creds-anon,id=tls0,endpoint=server \
  -vnc hostname:0,tls-creds=tls0

Old syntax for x509 credentials, no client certs:

  -vnc hostname:0,tls,x509=/path/to/certs

New syntax:

  -object tls-creds-x509,id=tls0,dir=/path/to/certs,endpoint=server,verify-peer=no \
  -vnc hostname:0,tls-creds=tls0

Old syntax for x509 credentials, requiring client certs:

  -vnc hostname:0,tls,x509verify=/path/to/certs

New syntax:

  -object tls-creds-x509,id=tls0,dir=/path/to/certs,endpoint=server,verify-peer=yes \
  -vnc hostname:0,tls-creds=tls0

This aligns VNC with the way TLS credentials are to be
configured in the future for chardev, nbd and migration
backends. It also has the benefit that the same TLS
credentials can be shared across multiple VNC server
instances, if desired.

If someone uses the deprecated syntax, it will internally
result in the creation of a 'tls-creds' object with an ID
based on the VNC server ID. This allows backwards compat
with the CLI syntax, while still deleting all the original
TLS code from the VNC server.

2cb5d2a47c gtk: use setlocale() for LC_MESSAGES only
The QEMU code is not internationalized and assumes that it runs under
the C locale, but if we use the GTK+ UI we'll end up importing the
locale settings from the environment. This can break things, such as
the JSON generator and iotest 120 in locales that use a decimal comma.

We do however have translations for a few simple strings for the GTK+
menu items, so in order to run QEMU using the C locale, and yet have a
translated UI let's use setlocale() for LC_MESSAGES only.

Kick off all grabbing logic from fullscreen mode.  In the current state
it seems to create more problems than it solves.  Try running qemu/gtk
fullscreen on one head of a multihead host for example ...

There probably was a reason the grab-on-fullscreen logic was added in
the first place.  So please test and report any issues so we can try to
find a sane way to handle it.

eb8934b041 vnc: fix memory corruption (CVE-2015-5225)
The _cmp_bytes variable added by commit "bea60dd ui/vnc: fix potential
memory corruption issues" can become negative.  Result is (possibly
exploitable) memory corruption.  Reason for that is it uses the stride
instead of bytes per scanline to apply limits.

For the server surface is is actually fine.  vnc creates that itself,
there is never any padding and thus scanline length always equals stride.

For the guest surface scanline length and stride are typically identical
too, but it doesn't has to be that way.  So add and use a new variable
(guest_ll) for the guest scanline length.  Also rename min_stride to
line_bytes to make more clear what it actually is.  Finally sprinkle
in an assert() to make sure we never use a negative _cmp_bytes again.

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().

08d49df0db sdl2: fix crash in handle_windowevent() when restoring the screen size
The Ctrl-Alt-u keyboard shortcut restores the screen to its original
size. In the SDL2 UI this is done by destroying the window and
creating a new one. The old window emits SDL_WINDOWEVENT_HIDDEN when
it's destroyed, but trying to call SDL_GetWindowFromID() from that
event's window ID returns a null pointer. handle_windowevent() assumes
that the pointer is never null so it results in a crash.

1640b200d5 QemuOpts: Drop qemu_opt_foreach() parameter abort_on_failure
When the argument is non-zero, qemu_opt_foreach() stops on callback
returning non-zero, and returns that value.

When the argument is zero, it doesn't stop, and returns the callback's
value from the last iteration.

The two callers that pass zero could just as well pass one:

* qemu_spice_init()'s callback add_channel() either returns zero or
  exit()s.

* config_write_opts()'s callback config_write_opt() always returns
  zero.

Drop the parameter, and always stop.

42af3e3a02 ui/console: remove dpy_gfx_update_dirty
dpy_gfx_update_dirty expects DIRTY_MEMORY_VGA logging to be always on,
but that will not be the case soon.  Because it computes the memory
region on the fly for every update (with memory_region_find), it cannot
enable/disable logging by itself.

We could always treat updates as invalidations if dirty logging is
not enabled, assuming that the board will enable logging on the
RAM region that includes the framebuffer.

However, the function is unused, so just drop it.

Note that gtk got native opengl support with release 3.16.

b771f470f3 kbd: add brazil kbd keys to qemu
The brazilian computer keyboard layout has two extra keys (compared to
the usual 105-key intl ps/2 keyboard).  This patch makes these two keys
known to qemu.

For historic reasons qemu has two ways to specify a key:  A QKeyCode
(name-based) or a number (ps/2 scancode based).  Therefore we have to
update multiple places to make new keys known to qemu:

  (1) The QKeyCode definition in qapi-schema.json
  (2) The QKeyCode <-> number mapping table in ui/input-keymap.c

This patch does just that.  With this patch applied you can send those
two keys to the guest using the send-key monitor command.

In OSX 10.10, the NSOKButton and NSCancelButton constants are deprecated

NSFileHandlingPanelCancelButton and NSFileHandlingPanelOKButton constants
instead. These are the documented correct constants for the 10.6-and-up
beginSheetModalForWindow API we use. We also use the same method for
the pre-10.6 compatibility code path, but conveniently the constant
values are the same and the constant names have been present since 10.0.
Preferring the constant names that match the non-legacy API makes more
sense anyway.

b63901d84c ui/cocoa: Drop tests for CGImageCreateWithImageInRect support
The code that tries to test at both compiletime and runtime
for whether CGImageCreateWithImageInRect is supported provokes
a compile warning on OSX 10.3:

ui/cocoa.m:378:13: warning: comparison of function 'CGImageCreateWithImageInRect'
      equal to a null pointer is always false[-Wtautological-pointer-compare]
        if (CGImageCreateWithImageInRect == NULL) { // test if "CGImageCreateWithImageInRect" is
supported on host at runtime
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~    ~~~~

The simplest way to deal with this is just to drop this code,
since we don't in practice support OSX 10.4 anyway. (10.5 was
released in 2007 and is the last PPC version, so is the earliest
we really need to continue to support at all.)

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

2cdb5e142f CVE-2015-1779: limit size of HTTP headers from websockets clients
The VNC server websockets decoder will read and buffer data from
websockets clients until it sees the end of the HTTP headers,
as indicated by \r\n\r\n. In theory this allows a malicious to
trick QEMU into consuming an arbitrary amount of RAM. In practice,
because QEMU runs g_strstr_len() across the buffered header data,
it will spend increasingly long burning CPU time searching for
the substring match and less & less time reading data. So while
this does cause arbitrary memory growth, the bigger problem is
that QEMU will be burning 100% of available CPU time.

A novnc websockets client typically sends headers of around
512 bytes in length. As such it is reasonable to place a 4096
byte limit on the amount of data buffered while searching for
the end of HTTP headers.

a2bebfd6e0 CVE-2015-1779: incrementally decode websocket frames
The logic for decoding websocket frames wants to fully
decode the frame header and payload, before allowing the
VNC server to see any of the payload data. There is no
size limit on websocket payloads, so this allows a
malicious network client to consume 2^64 bytes in memory
in QEMU. It can trigger this denial of service before
the VNC server even performs any authentication.

The fix is to decode the header, and then incrementally
decode the payload data as it is needed. With this fix
the websocket decoder will allow at most 4k of data to
be buffered before decoding and processing payload.

51941e4695 ui: enforce TLS when using websockets server
When TLS is required, the primary VNC server considers it to be
mandatory. ie the server admin decides whether or not TLS is used,
and the client has to comply with this decision. The websockets
server, however, treated it as optional, allowing non-TLS clients
to connect to a server which had setup TLS. Thus enabling websockets
lowers the security of the VNC server leaving the admin no way to
enforce use of TLS.

This removes the code that allows non-TLS fallback in the websockets
server, so that if TLS is requested for VNC it is now mandatory for
both the primary VNC server and the websockets VNC server.

f9148c8ae7 ui: fix setup of VNC websockets auth scheme with TLS
The way the websockets TLS code was integrated into the VNC server
made it essentially useless. The only time that the websockets TLS
support could be used is if the primary VNC server had its existing
TLS support disabled. ie QEMU had to be launched with:

  # qemu -vnc localhost:1,websockets=5902,x509=/path/to/certs

Note the absence of the 'tls' flag. This is already a bug, because
the docs indicate that 'x509' is ignored unless 'tls' is given.

If the primary VNC server had TLS turned on via the 'tls' flag,
then this prevented the websockets TLS support from being used,
because it activates the VeNCrypt auth which would have resulted
in TLS being run over a TLS session. Of course no websockets VNC
client supported VeNCrypt so in practice, since the browser clients
cannot setup a nested TLS session over the main HTTPS connection,
so it would not even get past auth.

This patch causes us to decide our auth scheme separately for the
main VNC server vs the websockets VNC server. We take account of
the fact that if TLS is enabled, then the websockets client will
use https, so setting up VeNCrypt is thus redundant as it would
lead to nested TLS sessions.

d169f04b8b ui: report error if user requests VNC option that is unsupported
If the VNC server is built without tls, sasl or websocket support
and the user requests one of these features, they are just silently
ignored. This is bad because it means the VNC server ends up running
in a configuration that is less secure than the user asked for.
It also leads to an tangled mass of preprocessor conditionals when
configuring the VNC server.

This ensures that the tls, sasl & websocket options are always
processed and an error is reported back to the user if any of
them were disabled at build time.

8c7d064573 ui: fix regression in x509verify parameter for VNC server
The 'x509verify' parameter is documented as taking a path to the
x509 certificates, ie the same syntax as the 'x509' parameter.

  commit 4db14629c3
  Author: Gerd Hoffmann <kraxel@redhat.com>
  Date:   Tue Sep 16 12:33:03 2014 +0200

    vnc: switch to QemuOpts, allow multiple servers

caused a regression by turning 'x509verify' into a boolean
parameter instead. This breaks setup from libvirt and is not

3e5a50d64c hmp: Name HMP command handler functions hmp_COMMAND()
Some are called do_COMMAND() (old ones, usually), some hmp_COMMAND(),
and sometimes COMMAND pointlessly differs in spelling.

Normalize to hmp_COMMAND(), where COMMAND is exactly the command name
with '-' replaced by '_'.

Exceptions:

* do_device_add() and client_migrate_info() *not* renamed to
  hmp_device_add(), hmp_client_migrate_info(), because they're also
  QMP handlers.  They still need to be converted to QAPI.

* do_memory_dump(), do_physical_memory_dump(), do_ioport_read(),
  do_ioport_write() renamed do hmp_* instead of hmp_x(), hmp_xp(),
  hmp_i(), hmp_o(), because those names are too cryptic for my taste.

* do_info_help() renamed to hmp_info_help() instead of hmp_info(),
  because it only covers help.

 * Each vnc server returns a list of server sockets.  Followup patch
   will use that to also report websockets.  In case we add support for

e5f34cdd2d vnc: track & limit connections
Also track the number of connections in "connecting" and "shared" state
(in addition to the "exclusive" state).  Apply a configurable limit to
these connections.

The logic to apply the limit to connections in "shared" state is pretty
simple:  When the limit is reached no new connections are allowed.

The logic to apply the limit to connections in "connecting" state (this
is the state you are in *before* successful authentication) is
slightly different:  A new connect kicks out the oldest client which is
still in "connecting" state.  This avoids a easy DoS by unauthenticated
users by simply opening connections until the limit is reached.

d3f3a0f453 sdl2: Work around SDL2 SDL_ShowWindow() bug
Apparently it is possible for X to send an event to a hidden SDL2
window, leading to SDL2 believing it is now shown. SDL2 will pass the
SDL_WINDOWEVENT_SHOWN message to the application without actually
showing the window; the problem is that the next SDL_ShowWindow() will
be a no-op because SDL2 assumes the window is already shown.

The correct way to react to SDL_WINDOWEVENT_SHOWN would be to clear
scon->hidden (analogous for SDL_WINDOWEVENT_HIDDEN). However, due to the
window not actually being shown, this will somehow not be correct after
all.

Therefore, just hide the window on SDL_WINDOWEVENT_SHOWN if it is
supposed to be hidden (and analogous for SDL_WINDOWEVENT_HIDDEN).

1dfc5c8808 sdl2: Use correct sdl2_console for window events
SDL_PollEvent() polls events for all windows; therefore,
sdl2_poll_events() will poll the events for all windows and not only for
the one identified by the given sdl2_console.

This should be considered in handle_windowevent(): The window affected
by the event is not necessarily the one identified by the sdl2_console
object given to sdl2_poll_events(), but the one identified by
ev->window.windowID.

a41642708a spice: fix memory leak
If errors happen for middle items of channel_list,
qmp_query_spice_channels() returns NULL, and the variable
cur_item going out of scope leaks the storage it points to.

The flag is a compatibility thing for older spice-server
versions. Meanwhile our minimum spice version requirement is
new enough that we should never ever see this error, and if we
do something went very seriously wrong. Let's using assert()
instead of returning NULL to avoid a memory leak.

51fc44768a QMP/input-send-event: make console parameter optional
The 'QemuConsole' is the input source for handler, we share some
input handlers to process the input events from different QemuConsole.

Normally we only have one set of keyboard, mouse, usbtablet, etc.
The devices have different mask, it's fine to just checking mask to
insure that the handler has the ability to process the event.

I saw we try to bind console to handler in usb/dev-hid.c, but display
always isn't available at that time.

If we have multiseat setup (as Gerd said), we only have 'problem' in
this case. Actually event from different devices have the same effect
for system, it's fine to always use the first available handler
without caring about the console.

For send-key command, we just pass a NULL for console parameter in
calling qemu_input_event_send_key(NULL, ..), but 'input-send-event'
needs to care more devices.

Conclusion:
Generally assigning the special console is meanless, and we can't
directly remove the QMP parameter for compatibility.

So we can make the parameter optional. The parameter might be useful
for some special condition: we have multiple devices without binding
console and they all have the ability(mask) to process events, and
we don't want to use the first one.

b0f3182064 gtk: Hide the menubar when in fullscreen mode (lp 1294898)
In fullscreen mode, we attempt to shrink the menubar to 1 pixel in height,
so it takes up as little room as possible while still allowing us to use
the keyboard shortcuts for its various operations.

However this shrinking is disregarded on gtk3, so the entire menu bar is
visible, which isn't very pleasant. This patch hides the menu bar instead.

The side effect is that the only keyboard shortcuts that will work in this
mode are the ones that we explicitly register on the top level window and
not the menu bar. The previous patches changed the fullscreen and vc
shortcuts to work like that, which I think are the only ones that really
matter in for the fullscreen case.

550830f935 block: delete cow block driver
This patch removes support for the cow file format.

Normally we do not break backwards compatibility but in this case there
is no impact and it is the most logical option.  Extraordinary claims
require extraordinary evidence so I will show why removing the cow block
driver is the right thing to do.

The cow file format is the disk image format for Usermode Linux, a way
of running a Linux system in userspace.  The performance of UML was
never great and it was hacky, but it enjoyed some popularity before
hardware virtualization support became mainstream.

QEMU's block/cow.c is supposed to read this image file format.
Unfortunately the file format was underspecified:

1. Earlier Linux versions used the MAXPATHLEN constant for the backing
   filename field.  The value of MAXPATHLEN can change, so Linux
   switched to a 4096 literal but QEMU has a 1024 literal.

2. Padding was not used on the header struct (both in the Linux kernel
   and in QEMU) so the struct layout varied across architectures.  In
   particular, i386 and x86_64 were different due to int64_t alignment
   differences.  Linux now uses __attribute__((packed)), QEMU does not.

Therefore:

1. QEMU cow images do not conform to the Linux cow image file format.

2. cow images cannot be shared between different host architectures.

This means QEMU cow images are useless and QEMU has not had bug reports
from users actually hitting these issues.

Let's get rid of this thing, it serves no purpose and no one will be
affected.

This may delay sensitive updates as mouse movements or typing in the console.
As we currently prepare all data in a buffer and then send as much as we can
disabling the Nagle algorithm should not cause big trouble. Well established
VNC servers like TightVNC set TCP_NODELAY as well.
A regular framebuffer update request generates exactly one framebuffer update

30f1e661b6 console: stop using PixelFormat
With this patch the qemu console core stops using PixelFormat and pixman
format codes side-by-side, pixman format code is the primary way to
specify the DisplaySurface format:

 * DisplaySurface stops carrying a PixelFormat field.
 * qemu_create_displaysurface_from() expects a pixman format now.

Functions to convert PixelFormat to pixman_format_code_t (and back)
exist for those who still use PixelFormat.   As PixelFormat allows
easy access to masks and shifts it will probably continue to exist.

ab9509ccea spice: make sure we don't overflow ssd->buf
Related spice-only bug.  We have a fixed 16 MB buffer here, being
presented to the spice-server as qxl video memory in case spice is
used with a non-qxl card.  It's also used with qxl in vga mode.

When using display resolutions requiring more than 16 MB of memory we
are going to overflow that buffer.  In theory the guest can write,
indirectly via spice-server.  The spice-server clears the memory after
setting a new video mode though, triggering a segfault in the overflow
case, so qemu crashes before the guest has a chance to do something
evil.

Fix that by switching to dynamic allocation for the buffer.

e72b59fa93 ui/gtk: Restore keyboard focus after Page change
(Resending for correct email addresses via MAINTAINERS ...)

In the GTK UI, after changing focus to the qemu monitor Notebook Page,
when restoring focus to the virtual machine page, the keyboard focus is lost
to a hidden GTK widget. Focus can only be restored to the virtual machine by
pressing "tab" or any of the four directional arrow keys.

Clicking in the window or grabbing/ungrabbing input does not restore keyboard
focus to the child widget.

This patch adjusts the Notebook page switching callback to automatically
steal keyboard focus on the Page switch event, so that keyboard input
does not appear to break or disappear after tabbing to the QEMU monitor.

bea60dd767 ui/vnc: fix potential memory corruption issues
this patch makes the VNC server work correctly if the
server surface and the guest surface have different sizes.

Basically the server surface is adjusted to not exceed VNC_MAX_WIDTH
x VNC_MAX_HEIGHT and additionally the width is rounded up to multiple of
VNC_DIRTY_PIXELS_PER_BIT.

If we have a resolution whose width is not dividable by VNC_DIRTY_PIXELS_PER_BIT
we now get a small black bar on the right of the screen.

If the surface is too big to fit the limits only the upper left area is shown.

On top of that this fixes 2 memory corruption issues:

The first was actually discovered during playing
around with a Windows 7 vServer. During resolution
change in Windows 7 it happens sometimes that Windows
changes to an intermediate resolution where
server_stride % cmp_bytes != 0 (in vnc_refresh_server_surface).
This happens only if width % VNC_DIRTY_PIXELS_PER_BIT != 0.

The second is a theoretical issue, but is maybe exploitable
by the guest. If for some reason the guest surface size is bigger
than VNC_MAX_WIDTH x VNC_MAX_HEIGHT we end up in severe corruption since
this limit is nowhere enforced.

f9a70e7939 ui/vnc: limit client_cut_text msg payload size
currently a malicious client could define a payload
size of 2^32 - 1 bytes and send up to that size of
data to the vnc server. The server would allocated
that amount of memory which could easily create an
out of memory condition.

This patch limits the payload size to 1MB max.

Please note that client_cut_text messages are currently
silently ignored.

f61c387ea6 ui/cocoa: Fix handling of absolute positioning devices
Fix handling of absolute positioning devices, which were basically
unusable for two separate reasons:
 (1) as soon as you pressed the left mouse button we would call
     CGAssociateMouseAndMouseCursorPosition(FALSE), which means that
     the absolute coordinates of the mouse events are never updated
 (2) we didn't account for MacOSX coordinate origin being bottom left
     rather than top right, and so all the Y values sent to the guest
     were inverted

We fix (1) by aligning our behaviour with the SDL UI backend for
absolute devices:
 * when the mouse moves into the window we do a grab (which means
   hiding the host cursor and sending special keys to the guest)
 * when the mouse moves out of the window we un-grab
and fix (2) by doing the correct transformation in the call to
qemu_input_queue_abs().

381600dad9 ui/cocoa: Cope with first surface being same as initial window size
Do the recalculation of the content dimensions in switchSurface if the
current cdx is zero as well as if the new surface is a different size to
the current window. This catches the case where the first surface registered
happens to be 640x480 (our current window size), and fixes a bug where we
would always display a black screen until the first surface of a different
size was registered.

82fc18099a gtk: window sizing overhaul
Major overhaul for window size handling.  This basically switches qemu
over to use geometry hints for the window manager instead of trying to
get the job done with widget resize requests.  This allows to specify
better what we need and also avoids window resizes.

FIXME: on gtk2 someone overwrites the geometry hints :(

800b0e814b gtk: Implement grab-on-click behavior in relative mode
This patch changes the behavior in the relative mode to be compatible
with other UIs, namely, grabbing the input at the first left click.
It improves the usability a lot; otherwise you have to press ctl-alt-G
or select from menu at each time you want to move the pointer.  Also,
the input grab is cleared when the current mode is switched to the
absolute mode.

The automatic reset of the implicit grabbing is needed since the
switching to the absolute mode happens always after the click even on
Gtk.  That is, we cannot check whether the absolute mode is already
available at the first click time even though it should have been
switched in X11 input driver side.

ecce1929bc gtk: Remember the last grabbed pointer position
It's pretty annoying that the pointer reappears at a random place once
after grabbing and ungrabbing the input.  Better to restore to the
original position where the pointer was grabbed.

e61031cdd8 gtk: Fix the relative pointer tracking mode
The relative pointer tracking mode was still buggy even after the
previous fix of the motion-notify-event since the events are filtered
out when the pointer moves outside the drawing window due to the
boundary check for the absolute mode.

This patch fixes the issue by moving the unnecessary boundary check
into the if block of absolute mode, and keep the coordinate in the
relative mode even if it's outside the drawing area.  But this makes
the coordinate (last_x, last_y) possibly pointing to (-1,-1),
introduce a new flag to indicate the last coordinate has been
updated.

0d0e044dee gtk: Use gtk generic event signal instead of motion-notify-event
The GDK motion-notify-event isn't generated when the pointer goes out
of the target window even if the pointer is grabbed, which essentially
means to lose the pointer tracking in gtk-ui.

Meanwhile the generic "event" signal is sent when the pointer is
grabbed, so we can use this and pick the motion notify events manually
there instead.

39f72ef94b qom: Add check() argument to object_property_add_link()
There are currently three types of object_property_add_link() callers:

1. The link property may be set at any time.
2. The link property of a DeviceState instance may only be set before
   realize.
3. The link property may never be set, it is read-only.

Something similar can already be achieved with
object_property_add_str()'s set() argument.  Follow its example and add
a check() argument to object_property_add_link().

Also provide default check() functions for case #1 and #2.  Case #3 is
covered by passing a NULL function pointer.

9561fda8d9 qom: Make QOM link property unref optional
Some object_property_add_link() callers expect property deletion to
unref the link property object.  Other callers expect to manage the
refcount themselves.  The former are currently broken and therefore leak
the link property object.

This patch adds a flags argument to object_property_add_link() so the
caller can specify which refcount behavior they require.  The new
OBJ_PROP_LINK_UNREF_ON_RELEASE flag causes the link pointer to be
unreferenced when the property is deleted.

This fixes refcount leaks in qdev.c, xilinx_axidma.c, xilinx_axienet.c,
s390-virtio-bus.c, virtio-pci.c, virtio-rng.c, and ui/console.c.

Rationale for refcount behavior:

 * hw/core/qdev.c
   - bus children are explicitly unreferenced, don't interfere
   - parent_bus is essentially a read-only property that doesn't hold a
     refcount, don't unref
   - hotplug_handler is leaked, do unref

 * hw/dma/xilinx_axidma.c
   - rx stream "dma" links are set using set_link, therefore they
     need unref
   - tx streams are set using set_link, therefore they need unref

 * hw/net/xilinx_axienet.c
   - same reasoning as hw/dma/xilinx_axidma.c

 * hw/pcmcia/pxa2xx.c
   - pxa2xx bypasses set_link and therefore does not use refcounts

 * hw/s390x/s390-virtio-bus.c
 * hw/virtio/virtio-pci.c
 * hw/virtio/virtio-rng.c
 * ui/console.c
   - set_link is used and there is no explicit unref, do unref

You can see this error in action by using -vga qxl, however even after this
patch the mouse warps in small increments up and to the left, -7x and -3y
pixels at a time, until the pointer is warped off the widget. I think it's
a qxl bug, but the next patch covers it up.

All bits clean - vnc_update_client_new: 0.07 secs

                 vnc_update_client_old: 10.98 secs

All bits dirty - vnc_update_client_new: 11.26 secs
               - vnc_update_client_new2: 0.29 secs
                 vnc_update_client_old: 20.19 secs

Few bits dirty - vnc_update_client_new: 0.07 secs
               - vnc_update_client_new2: 0.07 secs
                 vnc_update_client_old: 10.98 secs

vnc_update_client_new2 shows the performance of vnc_update_client
with this patch added.

Comparing with the test run of the last patch the performance
is at least unchanged while it is significantly improved
for the all bits dirty case.

12b316d4c1 ui/vnc: optimize dirty bitmap tracking
vnc_update_client currently scans the dirty bitmap of each client
bitwise which is a very costly operation if only few bits are dirty.
vnc_refresh_server_surface does almost the same.
this patch optimizes both by utilizing the heavily optimized
function find_next_bit to find the offset of the next dirty
bit in the dirty bitmaps.

The following artifical test (just the bitmap operation part) running
vnc_update_client 65536 times on a 2560x2048 surface illustrates the
performance difference:

All bits clean - vnc_update_client_new: 0.07 secs
 vnc_update_client_old: 10.98 secs

All bits dirty - vnc_update_client_new: 11.26 secs
 vnc_update_client_old: 20.19 secs

Few bits dirty - vnc_update_client_new: 0.08 secs
 vnc_update_client_old: 10.98 secs

The case for all bits dirty is still rather slow, this
is due to the implementation of find_and_clear_dirty_height.
This will be addresses in a separate patch.

38ee14f4f3 vnc: fix use-after-free in vnc_update_client_sync
Spotted by Coverity:

876     static int vnc_update_client_sync(VncState *vs, int has_dirty)
877     {

(1) Event freed_arg:    "vnc_update_client(VncState *, int)" frees "vs".  [details]
Also see events:        [deref_arg]

878         int ret = vnc_update_client(vs, has_dirty);

(2) Event deref_arg:    Calling "vnc_jobs_join(VncState *)" dereferences freed pointer "vs". [details]
Also see events:        [freed_arg]

879         vnc_jobs_join(vs);
880         return ret;
881     }

Remove vnc_update_client_sync wrapper, replace it with an additional
argument to vnc_update_client, so we can so the sync properly in
vnc_update_client (i.e. skip it in case of a client disconnect).

e3c1adf16e vnc: Fix qemu crashed when vnc client disconnect suddenly
Hi,

When I use RealVNC viewer client (http://www.realvnc.com/) to connect vnc server,
the client disconnect suddenly, and I click reconnect button immediately, then the Qemu crashed.

In the function vnc_worker_thread_loop, will call vnc_async_encoding_start
to set the local vs->output buffer by global queue's buffer. Then send rectangles to
the vnc client call function vnc_send_framebuffer_update. Finally, Under normal circumstances,
call vnc_async_encoding_end to set the global queue'buffer by the local vs->output conversely.

When the vnc client disconnect, the job->vs->csock will be set to -1. And the current prcoess
logic will goto disconnected partion without call function vnc_async_encoding_end.
But, the function vnc_send_framebuffer_update will call buffer_reserve, which
maybe call g_realloc reset the local vs's buffer, meaning the global queue's buffer is modified also.
If anyone use the original global queue's buffer memory will cause corruption and then crash qemu.

This patch assure the function vnc_async_encoding_end being called
even though the vnc client disconnect suddenly.

2e7bcdb99a vnc: Fix tight_detect_smooth_image() for lossless case
VncTight member uint8_t quality is either (uint8_t)-1 for lossless or
less than 10 for lossy.

tight_detect_smooth_image() first promotes it to int, then compares
with -1.  Always unequal, so we always execute the lossy code.  Reads
beyond tight_conf[] and returns crap when quality is actually
lossless.

Compare to (uint8_t)-1 instead, like we do elsewhere.

47c03744b3 ui/sdl2 : initial port to SDL 2.0 (v2.0)
I've ported the SDL1.2 code over, and rewritten it to use the SDL2 interface.

The biggest changes were in the input handling, where SDL2 has done a major
overhaul, and I've had to include a generated translation file to get from
SDL2 codes back to qemu compatible ones. I'm still not sure how the keyboard
layout code works in qemu, so there may be further work if someone can point
me a test case that works with SDL1.2 and doesn't with SDL2.

Some SDL env vars we used to set are no longer used by SDL2,
Windows, OSX support is untested,

I don't think we can link to SDL1.2 and SDL2 at the same time, so I felt
using --with-sdlabi=2.0 to select the new code should be fine, like how
gtk does it.

v1.1: fix keys in text console
v1.2: fix shutdown, cleanups a bit of code, support ARGB cursor

v2.0: merge the SDL multihead patch into this, g_new the number of consoles
needed, wrap DCL inside per-console structure.
