2023-09-04ui/gtk: fix leaks found wtih fuzzingDmitry Frolov1-1/+2
It is true, that there is no problem during runtime from the first sight, because the memory is lost just before qemu exits. Nevertheless, this change is necessary, because AddressSanitizer is not able to recognize this situation and produces crash-report (which is false-positive in fact). Lots of False-Positive warnings are davaluing problems, found with fuzzing, and thus the whole methodology of dynamic analysis. This patch eliminates such False-Positive reports, and makes every problem, found with fuzzing, more valuable.

2023-09-04ui/dbus: implement damage regions for GLBilal Elmoussaoui1-7/+25
Currently, when using `-display dbus,gl=on` all updates to the client become "full scanout" updates, meaning there is no way for the client to limit damage regions to the display server. Instead of using an "update count", this patch tracks the damage region and propagates it to the client. This was less of an issue when clients were using GtkGLArea for rendering, as you'd be doing full-surface redraw. To be efficient, the client needs both a DMA-BUF and the damage region to be updated.

Use autofree heap allocation instead of variable-length array on the stack. The codebase has very few VLAs, and if we can get rid of them all we can make the compiler error on new additions.

2023-09-04ui/vnc-enc-hextile: Use static rather than dynamic length stack arrayPeter Maydell1-1/+7
In the send_hextile_tile_* function we create a variable length array data[]. In fact we know that the client_pf.bytes_per_pixel is at most 4 (enforced by set_pixel_format()), so we can make the array a compile-time fixed length of 1536 bytes. The codebase has very few VLAs, and if we can get rid of them all we can make the compiler error on new additions.

2023-09-04ui/vc: do not parse VC-specific options in Spice and GTKMarc-André Lureau3-4/+8
In commit 6f974c843c ("gtk: overwrite the console.c char driver"), I shared the VC console parse handler with GTK. And later on in commit d8aec9d9 ("display: add -display spice-app launching a Spice client"), I also used it to handle spice-app VC. This is not necessary, the VC console options (width/height/cols/rows) are specific, and unused by tty-level GTK/Spice VC. This is not a breaking change, as those options are still being parsed by QAPI ChardevVC. Adjust the documentation about it.

Although at this point only QemuGraphicConsole have hw_ops that implements ui_info() callback, it makes sense to keep the code in the base QemuConsole, to simplify conditions for the caller. As of now, the code didn't reach a NULL timer because dpy_set_ui_info() checks if dpy_ui_info_supported() (hw_ops->ui_info != NULL), which is false for text_console_ops.

There is no obvious reason to defer text console initialization. We can simply take the global display state in new_console(). This simplify somewhat the code to allow moving the VC to a separate unit. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Daniel P.

2023-09-01ui/console: call dpy_gfx_update() regardless of have_gfxMarc-André Lureau1-1/+1
The function will handle the case when no listeners are gfx, without extra meaningful cost. This allows to get rid of DisplayState dependency in VC implementation.

2023-09-01ui/console: console_select() regardless of have_gfxMarc-André Lureau1-6/+4
Even if we don't have a gfx listener, we should call displaychangelistener_display_console() which handle that case correctly.

2023-09-01ui/vc: drop have_textMarc-André Lureau1-29/+13
If there are no "text" listener, the callback will simply be ignored. The rest of text handling can be done cheaply. This allows to remove some dependency on DisplayState from VC implementation.

2023-09-01ui/vc: replace vc_chr_write() with generic qemu_chr_write()Marc-André Lureau1-3/+3
We shouldn't call the callback directly, but use the chardev API, unless there is a clear reason. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Daniel P.
