When starting a guest via libvirt with "virsh start --console ...",
the first second of the console output is missing. This is especially
annoying on s390x that only has a text console by default and no graphical
output - if the bios fails to boot here, the information about what went
wrong is completely lost.
One part of the problem (there is also some things to be done on the
libvirt side) is that QEMU only checks with a 1 second timer whether
the other side of the pty is already connected, so the first second of
the console output is always lost.
This likely used to work better in the past, since the code once checked
for a re-connection during write, but this has been removed in commit
f8278c7d74 ("char-pty: remove the check for connection on write") to avoid
some locking.
To ease the situation here at least a little bit, let's check with g_poll()
whether we could send out the data anyway, even if the connection has not
been marked as "connected" yet. The file descriptor is marked as non-blocking
anyway since commit fac6688a18 ("Do not hang on full PTY"), so this should
not cause any trouble if the other side is not ready for receiving yet.
With this patch applied, I can now successfully see the bios output of
a s390x guest when running it with "virsh start --console" (with a patched
version of virsh that fixes the remaining issues there, too).

The fw_cfg DMA write callback in ramfb prepares a new display surface in
QEMU; this new surface is put to use ("swapped in") upon the next display
update. At that time, the old surface (if any) is released.
If the guest triggers the fw_cfg DMA write callback at least twice between
two adjacent display updates, then the second callback (and further such
callbacks) will leak the previously prepared (but not yet swapped in)
display surface.
The issue can be shown by:
(1) starting QEMU with "-trace displaysurface_free", and
(2) running the following program in the guest UEFI shell:
> #include <Library/ShellCEntryLib.h> // ShellAppMain()
> #include <Library/UefiBootServicesTableLib.h> // gBS
> #include <Protocol/GraphicsOutput.h> // EFI_GRAPHICS_OUTPUT_PROTOCOL
>
> INTN
> EFIAPI
> ShellAppMain (
> IN UINTN Argc,
> IN CHAR16 **Argv
> )
> {
> EFI_STATUS Status;
> VOID *Interface;
> EFI_GRAPHICS_OUTPUT_PROTOCOL *Gop;
> UINT32 Mode;
>
> Status = gBS->LocateProtocol (
> &gEfiGraphicsOutputProtocolGuid,
> NULL,
> &Interface
> );
> if (EFI_ERROR (Status)) {
> return 1;
> }
>
> Gop = Interface;

> Mode = 1;
> for ( ; ;) {

> if (EFI_ERROR (Status)) {
> break;
> }
>
> Mode = 1 - Mode;
> }
>
> return 1;
> }
The symptom is then that:
- only one trace message appears periodically,
- the time between adjacent messages keeps increasing -- implying that
some list structure (containing the leaked resources) keeps growing,
- the "surface" pointer is ever different.

We figured this wasn't a CVE-worthy problem, as only small amounts of
memory were leaked (the framebuffer itself is mapped from guest RAM, QEMU
only allocates administrative structures), plus libvirt restricts QEMU
memory footprint anyway, thus the guest can only DoS itself.
Plug the leak, by releasing the last prepared (not yet swapped in) display
surface, if any, in the fw_cfg DMA write callback.
Regarding the "reproducer", with the fix in place, the log is flooded with
trace messages (one per fw_cfg write), *and* the trace message alternates
between just two "surface" pointer values (i.e., nothing is leaked, the
allocator flip-flops between two objects in effect).
This issue appears to date back to the introducion of ramfb (995b30179b,
"hw/display: add ramfb, a simple boot framebuffer living in guest ram",
2018-06-18).

dpy_get_ui_info() shouldn't be called if the underlying GPU doesn't

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.

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.

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.

Commit 58d5870845 ("ui/console: move graphic fields to

the "device" property lookup in qemu_console_is_multihead() now crashes,

Although an input is routed depending on the console,
qemu_input_is_absolute() had no mechanism to specify the console.
Accept QemuConsole as an argument for qemu_input_is_absolute, and let
the display know the absolute/relative state for a particular console.

Now that all callers support setting an audiodev, forbid using the default
audiodev if -nodefaults is provided on the command line.

Starting from audio_driver_init, propagate errors via Error ** so that
audio_init_audiodevs can simply pass &error_fatal, and AUD_register_card
can signal faiure.

Many machine types have default audio devices with no way to set the underlying
audiodev. Instead of adding an option for each and every one of them, this new
property can be used as a default during machine initialisation when creating
such devices.

These have been deprecated for a long time, and the introduction of
-audio in 7.1.0 has cemented the new way of specifying an audio backend's
parameters. However, there is still a need for simple configuration
of the audio backend in the desktop case; therefore, if no audiodev is
passed to audio_init(), go through a bunch of simple Audiodev* structures
and pick the first that can be initialized successfully.
The only QEMU_AUDIO_* option that is left in, waiting for a better idea,
is QEMU_AUDIO_DRV=none which is used by qtest.
Remove all the parsing code, including the concept of "can_be_default"
audio drivers: now that audio_prio_list[] is only used in a single place,
wav can be excluded directly in that function.

An error is already printed by audio_driver_init, but we can make
it more precise if the driver can return an Error *.

Since all callers require a valid audiodev this function can now safely
abort in case of missing AudioState.
