fb22ee75b2 meson: Explicitly specify dbus-display1.h dependency
Explicitly specify dbus-display1.h as a dependency so that files
depending on it will not get compiled too early.

2e5c9d5462 ui/console: Fix console resize with placeholder surface
In `qemu_console_resize()`, the old surface of the console is keeped if the new
console size is the same as the old one. If the old surface is a placeholder,
and the new size of console is the same as the placeholder surface (640*480),
the surface won't be replace.
In this situation, the surface's `QEMU_PLACEHOLDER_FLAG` flag is still set, so
the console won't be displayed in SDL display mode.
This patch fixes this problem by forcing a new surface if the old one is a
placeholder.

it will be more obvious which assumption was violated.

480a6adc83 ui/clipboard: mark type as not available when there is no data
With VNC, a client can send a non-extended VNC_MSG_CLIENT_CUT_TEXT
message with len=0. In qemu_clipboard_set_data(), the clipboard info
will be updated setting data to NULL (because g_memdup(data, size)
returns NULL when size is 0). If the client does not set the
VNC_ENCODING_CLIPBOARD_EXT feature when setting up the encodings, then
the 'request' callback for the clipboard peer is not initialized.
Later, because data is NULL, qemu_clipboard_request() can be reached
via vdagent_chr_write() and vdagent_clipboard_recv_request() and
there, the clipboard owner's 'request' callback will be attempted to
be called, but that is a NULL pointer.

In particular, this can happen when using the KRDC (22.12.3) VNC
client.

Another scenario leading to the same issue is with two clients (say
noVNC and KRDC):

The noVNC client sets the extension VNC_FEATURE_CLIPBOARD_EXT and
initializes its cbpeer.

The KRDC client does not, but triggers a vnc_client_cut_text() (note
it's not the _ext variant)). There, a new clipboard info with it as
the 'owner' is created and via qemu_clipboard_set_data() is called,
which in turn calls qemu_clipboard_update() with that info.

In qemu_clipboard_update(), the notifier for the noVNC client will be
called, i.e. vnc_clipboard_notify() and also set vs->cbinfo for the
noVNC client. The 'owner' in that clipboard info is the clipboard peer
for the KRDC client, which did not initialize the 'request' function.
That sounds correct to me, it is the owner of that clipboard info.

Then when noVNC sends a VNC_MSG_CLIENT_CUT_TEXT message (it did set
the VNC_FEATURE_CLIPBOARD_EXT feature correctly, so a check for it
passes), that clipboard info is passed to qemu_clipboard_request() and
the original segfault still happens.

Fix the issue by handling updates with size 0 differently. In
particular, mark in the clipboard info that the type is not available.

While at it, switch to g_memdup2(), because g_memdup() is deprecated.

4fd56da337 ui: reject extended clipboard message if not activated
The extended clipboard message protocol requires that the client
activate the extension by requesting a psuedo encoding. If this
is not done, then any extended clipboard messages from the client
should be considered invalid and the client dropped.

ebfbf39467 ui/vnc-clipboard: fix inflate_buffer
Commit d921fea338 ("ui/vnc-clipboard: fix infinite loop in
inflate_buffer (CVE-2023-3255)") removed this hunk, but it is still
required, because it can happen that stream.avail_in becomes zero
before coming across a return value of Z_STREAM_END in the loop.

This fixes the host->guest direction of the clipboard with noVNC and
TigerVNC as clients.

53a939f1bf ui/gtk-egl: move function calls back to regular code path
Commit 6f189a08c1 ("ui/gtk-egl: Check EGLSurface before doing
scanout") introduced a regression when QEMU is running with a
virtio-gpu-gl-device on a host under X11. After the guest has
initialized the virtio-gpu-gl-device, the guest screen only
shows "Display output is not active.".

Commit 6f189a08c1 moved all function calls in
gd_egl_scanout_texture() to a code path which is only called
once after gd_egl_init() succeeds in gd_egl_scanout_texture().
Move all function calls in gd_egl_scanout_texture() back to
the regular code path so they get always called if one of the
gd_egl_init() calls was successful.

default VC then, and set them up to fix a regression when using remote

b7f1bb38b0 ui: use "vc" chardev for dbus, gtk & spice-app
Those display have their own implementation of "vc" chardev, which
doesn't use pixman. They also don't implement the width/height/cols/rows
options, so qemu_display_get_vc() should return a compatible argument.

This patch was meant to be with the pixman series, when the "vc" field
was introduced. It fixes a regression where VC are created on the
tty (or null) instead of the display own "vc" implementation.

547ec5a0a4 ui/sdl2: use correct key names in win title on mac
Previously, when using the SDL2 UI on MacOS, the title bar uses incorrect
key names (such as Ctrl and Alt instead of the standard MacOS key symbols
like ⌃ and ⌥). This commit changes sdl_update_caption in ui/sdl2.c to
use the correct symbols when compiling for MacOS (CONFIG_DARWIN is
defined).

Unfortunately, standard Mac keyboards do not include a "Right-Ctrl" key,
so in the case that the SDL grab mode is set to HOT_KEY_MOD_RCTRL, the
default text is still used.

1bec1cc0da ui/console: allow to override the default VC
If a display is backed by a specialized VC, allow to override the
default "vc:80Cx24C".

As suggested by Paolo, if the display doesn't implement a VC (get_vc()
returns NULL), use a fallback that will use a muxed console on stdio.

This changes the behaviour of "qemu -display none", to create a muxed
serial/monitor by default (on TTY & not daemonized).

6f189a08c1 ui/gtk-egl: Check EGLSurface before doing scanout
The first time gd_egl_scanout_texture() is called, there's a possibility
that the GTK drawing area might not be realized yet, in which case its
associated GdkWindow is NULL. This means gd_egl_init() was also skipped
and the EGLContext and EGLSurface stored in the VirtualGfxConsole are
not valid yet.

Continuing with the scanout in this conditions would result in hitting
an assert in libepoxy: "Couldn't find current GLX or EGL context".

A possible workaround is to just ignore the scanout request, giving the
the GTK drawing area some time to finish its realization. At that point,
the gd_egl_init() will succeed and the EGLContext and EGLSurface stored
in the VirtualGfxConsole will be valid.

d9cda21303 migration: simplify notifiers
Pass the callback function to add_migration_state_change_notifier so
that migration can initialize the notifier on add and clear it on
delete, which simplifies the call sites.  Shorten the function names
so the extra arg can be added more legibly.  Hide the global notifier
list in a new function migration_call_notifiers, and make it externally
visible so future live update code can call it.

No functional change.

c8a7fc5179 migration: simplify blockers
Modify migrate_add_blocker and migrate_del_blocker to take an Error **
reason.  This allows migration to own the Error object, so that if
an error occurs in migrate_add_blocker, migration code can free the Error
and clear the client handle, simplifying client code.  It also simplifies
the migrate_del_blocker call site.

In addition, this is a pre-requisite for a proposed future patch that would
add a mode argument to migration requests to support live update, and
maintain a list of blockers for each mode.  A blocker may apply to a single
mode or to multiple modes, and passing Error** will allow one Error object
to be registered for multiple modes.

No functional change.

9bd4d3df63 ui/gtk: fix UI info precondition
dpy_get_ui_info() shouldn't be called if the underlying GPU doesn't
support it.

Before the assert() was added and the regression introduced, GTK code
used to get "zero" UI info, for ex with a simple VGA device. The assert
was added to prevent from calling when there are no console too. The
other display backend that calls dpy_get_ui_info() correctly checks that
pre-condition.

Calling dpy_set_ui_info() is "safe" in this case, it will simply return
an error that can be generally ignored.

Fixes: commit a92e7bb4c ("ui: add precondition for dpy_get_ui_info()")

65d7ceb49b ui/console: sanitize search in qemu_graphic_console_is_multihead()
qemu_graphic_console_is_multihead() declares the graphical console "c" a
"multihead" console if there are two different graphical consoles in the
system that (a) both reference "c->device", and (b) have different
"c->head" numbers. In effect, if at least two graphical consoles exist
that are different heads of the same device that underlies "c". In fact,
"c" may be one of these two graphical consoles, or "c" may differ from
both of those consoles (in case "c->device" has at least three heads).

The loop currently uses this awkward "two different consoles" approach
because the function used not to have access to "c", only to "c->device",
which didn't allow for fetching (and comparing) "c->head". But, we've
changed that in the last patch; we now pass all of "c" to
qemu_graphic_console_is_multihead().

Thus, look for the *first* (and possibly *only*) graphical console, if
any, that refers to the same "device" as "c", but by a different "head"
number.

2c0c4c1f65 ui/console: eliminate QOM properties from qemu_console_is_multihead()
According to Marc-André's and Gerd's descriptions, the "device" and
"head" members of QemuGraphicConsole are exposed as QOM properties for two
purposes:

(1) Introspection (e.g., "qom-get" monitor command).

(2) A VNC server can display a specific device + head. This lets us run a
    multihead configuration by using multiple VNC servers (one for each
    head).

    Further, we can link input devices to device + head, so input events
    are routed to different devices dependent on where they are coming
    from. Which is most useful for tablet devices in a VNC multihead
    setup, each head has its own tablet device then. This does requires
    manual guest-side configuration, for establishing the same tablet <->
    head relationship.

However, neither goal seems to justify the complicated QOM property lookup
that's internal to qemu_console_is_multihead().

Rework qemu_console_is_multihead() with plain old C language field
accesses.

4ce2f97c00 ui/console: only walk QemuGraphicConsoles in qemu_console_is_multihead()
qemu_console_is_multihead() declares the console "c" a "multihead" console
if there are two different consoles in the system that (a) both reference
"c->device", and (b) have different "c->head" numbers. In effect, if at
least two consoles exist that are different heads of the same device that
underlies "c".

Commit 58d5870845 ("ui/console: move graphic fields to
QemuGraphicConsole", 2023-09-04) pushed the "device" and "head" members
from the QemuConsole base class down to the QemuGraphicConsole subclass,
adjusting the referring QOM properties accordingly as well. As a result,
the "device" property lookup in qemu_console_is_multihead() now crashes,
in case the candidate console being investigated for criterion (a) is not
a QemuGraphicConsole instance:

> Unexpected error in object_property_find_err() at qom/object.c:1314:
> qemu: Property 'qemu-fixed-text-console.device' not found
> Aborted (core dumped)

This is effectively an unchecked downcast. Make it checked: only consider
such console candidates that are themselves QemuGraphicConsole instances.
