5a4cb61ae1 ui/gtk: enable backend to send multi-touch events
GTK3 provides the infrastructure to receive and process multi-touch
events through the "touch-event" signal and the GdkEventTouch type.
Make use of it to transpose events from the host to the guest.

This allows users of machines with hardware capable of receiving
multi-touch events to run guests that can also receive those events
and interpret them as gestures, when appropriate.

An example of this in action can be seen here:

8e9ebd7523 virtio-input: add a virtio-mulitouch device
Add a virtio-multitouch device to the family of devices emulated by
virtio-input implementing the Multi-touch protocol as descripted here:

https://www.kernel.org/doc/html/latest/input/multi-touch-protocol.html?highlight=multi+touch

This patch just add the device itself, without connecting it to any
backends. The following patches will add a PCI-based multitouch device,
some helpers in "ui" and will enable the GTK3 backend to transpose
multi-touch events from the host to the guest.

4c93ce54e7 ui/cursor: make width/height unsigned 16-bit integer
Although not actually exploitable at the moment, a negative width/height
could make datasize wrap around and potentially lead to buffer overflow.
Since there is no reason a negative width/height is ever appropriate,
modify QEMUCursor struct and cursor_alloc prototype to accept uint16_t.
This protects us against accidentally introducing future bugs.

1dfea3f212 ui/sdl2: disable SDL_HINT_GRAB_KEYBOARD on Windows
Windows sends an extra left control key up/down input event for
every right alt key up/down input event for keyboards with
international layout. Since commit 830473455f ("ui/sdl2: fix
handling of AltGr key on Windows") QEMU uses a Windows low level
keyboard hook procedure to reliably filter out the special left
control key and to grab the keyboard on Windows.

The SDL2 version 2.0.16 introduced its own Windows low level
keyboard hook procedure to grab the keyboard. Windows calls this
callback before the QEMU keyboard hook procedure. This disables
the special left control key filter when the keyboard is grabbed.

To fix the problem, disable the SDL2 Windows low level keyboard
hook procedure.

efc00a3709 ui/sdl2: Grab Alt+Tab also in fullscreen mode

529969b8d0 virtio-gpu: add a FIXME for virtio_gpu_load()
It looks like the virtio_gpu_load() does not compute and set the offset,
the same way virtio_gpu_set_scanout() does. This probably results in
incorrect display until the scanout/framebuffer is updated again, I
guess we should fix it, although I haven't checked this yet.

d89f30b4df win32: wrap socket close() with an exception handler
Since commit abe34282 ("win32: avoid mixing SOCKET and file descriptor
space"), we set HANDLE_FLAG_PROTECT_FROM_CLOSE on the socket FD, to
prevent closing the HANDLE with CloseHandle. This raises an exception
which under gdb is fatal, and qemu exits.

Let's catch the expected error instead.

Note: this appears to work, but the mingw64 macro is not well documented
or tested, and it's not obvious how it is meant to be used.

f8a951bb95 ui/gtk-egl: fix scaling for cursor position in scanout mode
vc->gfx.w and vc->gfx.h are not updated appropriately in this code path,
which leads to a different scaling factor for rendering the cursor on
some edge cases (e.g. the focus has left and re-entered the gtk window).
This can be reproduced using vhost-user-gpu with the gtk ui on the x11
backend.
Use the surface dimensions which are already updated accordingly.

2f31663ed4 ui/gtk: use widget size for cursor motion event
The gd_motion_event size has some calculations for the cursor position,
which also take into account things like different size of the
framebuffer compared to the window size.
The use of window size makes things more difficult though, as at least
in the case of Wayland includes the size of ui elements like a menu bar
at the top of the window. This leads to a wrong position calculation by
a few pixels.
Fix it by using the size of the widget, which already returns the size
of the actual space to render the framebuffer.

2babbd9390 Hexagon: fix outdated hex_new_* comments
Some code comments refer to hex_new_value and hex_new_pred_value, which
have been transferred to DisasContext and, in the case of hex_new_value,
should now be accessed through get_result_gpr().

In order to fix this outdated comments and also avoid having to tweak
them whenever we make a variable name change in the future, let's
replace them with pseudocode.

3608c2419c target/hexagon/*.py: clean up used 'toss' and 'numregs' vars
Many Hexagon python scripts call hex_common.get_tagregs(), but only one
call site use the full reg structure given by this function. To make the
code cleaner, let's make get_tagregs() filter out the unused fields
(i.e. 'toss' and 'numregs'), properly removed the unused variables at
the call sites. The hex_common.bad_register() function is also adjusted
to work exclusively with 'regtype' and 'regid' args. For the single call
site that does use toss/numregs, we provide an optional parameter to
get_tagregs() which will restore the old full behavior.

3fd49e2217 Hexagon (target/hexagon) Fix assignment to tmp registers
The order in which instructions are generated by gen_insn() influences
assignment to tmp registers. During generation, tmp instructions (e.g.
generate_V6_vassign_tmp) use vreg_src_off() to determine what kind of
register to use as source. If some instruction (e.g.
generate_V6_vmpyowh_64_acc) uses a tmp register but is generated prior
to the corresponding tmp instruction, the vregs_updated_tmp bit map
isn't updated in time.

Exmple:
    { v14.tmp = v16; v25 = v14 } This works properly because
    generate_V6_vassign_tmp is generated before generate_V6_vassign
    and the bit map is updated.

    { v15:14.tmp = vcombine(v21, v16); v25:24 += vmpyo(v18.w,v14.h) }
    This does not work properly because vmpyo is generated before
    vcombine and therefore the bit map does not yet know that there's
    a tmp register.

The parentheses in the decoding function were in the wrong place.
Moving them to the correct location makes shuffling of .tmp vector
registers work as expected.

db01d85f16 meson: Add static glib dependency for initrd-stress.img
We recently moved glib detection code to meson but this changes the
linker command line from -lglib-2.0 to using a path to libglib-2.0.so.
This does not work for static linking, which is used by stress.c:

 $ make V=1 tests/migration/initrd-stress.img
 cc -m64 -mcx16 -o tests/migration/stress ... -static -Wl,--start-group
 /usr/lib64/libglib-2.0.so -Wl,--end-group
 ...
 bin/ld: attempted static link of dynamic object `/usr/lib64/libglib-2.0.so'

Add a specific dependency for stress.c, which is linked statically.
The compiler command line is now:

 cc -m64 -mcx16 -o tests/migration/stress ... -static -pthread
 -Wl,--start-group -lm /usr/lib64/libpcre.a -lglib-2.0 -Wl,--end-group

5b507233e6 configure: unset harmful environment variables
Apart from CLICOLOR_FORCE and GREP_OPTIONS, there are other variables
that are listed in the Autoconf manual.  While Autoconf neutralizes them
very early, and assumes it does not (yet) run in a shell that has "unset",
QEMU assumes that the user invoked configure under a POSIX shell, and
therefore can simply use "unset" to clear them.

CDPATH is particularly nasty because it messes up "cd ... && pwd".

b987718bbb hw/scsi/lsi53c895a: Fix reentrancy issues in the LSI controller (CVE-2023-0330)
We cannot use the generic reentrancy guard in the LSI code, so
we have to manually prevent endless reentrancy here. The problematic
lsi_execute_script() function has already a way to detect whether
too many instructions have been executed - we just have to slightly
change the logic here that it also takes into account if the function
has been called too often in a reentrant way.

The code in fuzz-lsi53c895a-test.c has been taken from an earlier
patch by Mauro Matteo Cascella.

d139fe9ad8 lsi53c895a: disable reentrancy detection for MMIO region, too
While trying to use a SCSI disk on the LSI controller with an
older version of Fedora (25), I'm getting:

 qemu: warning: Blocked re-entrant IO on MemoryRegion: lsi-mmio at addr: 0x34

and the SCSI controller is not usable. Seems like we have to
disable the reentrancy checker for the MMIO region, too, to
get this working again.

The problem could be reproduced it like this:

./qemu-system-x86_64 -accel kvm -m 2G -machine q35 \
 -device lsi53c810,id=lsi1 -device scsi-hd,drive=d0 \
 -drive if=none,id=d0,file=.../somedisk.qcow2 \
 -cdrom Fedora-Everything-netinst-i386-25-1.3.iso

Where somedisk.qcow2 is an image that contains already some partitions
and file systems.

In the boot menu of Fedora, go to
"Troubleshooting" -> "Rescue a Fedora system" -> "3) Skip to shell"

Then check "dmesg | grep -i 53c" for failure messages, and try to mount
a partition from somedisk.qcow2.
