ui/console: Private QemuDmaBuf struct

From: Dongwon Kim <dongwon.kim@intel.com> This series introduces privacy enhancements to the QemuDmaBuf struct and its contained data to bolster security. it accomplishes this by introducing of helper functions for allocating, deallocating, and accessing individual fields within the struct and replacing all direct references to individual fields in the struct with methods using helpers throughout the codebase. This change was made based on a suggestion from Marc-André Lureau <marcandre.lureau@redhat.com> (Resumitting same patch series with this new cover-leter) v6: fixed some typos in patch - ui/console: Introduce dpy_gl_qemu_dmabuf_get_..() helpers) v7: included minor fix (ui/gtk: Check if fence_fd is equal to or greater than 0) (Marc-André Lureau <marcandre.lureau@redhat.com>) migrated all helpers and QemuDmaBuf struct into dmabuf.c and their prototypes to dmabuf.h for better encapsulation (ui/dmabuf: New dmabuf.c and dmabuf.h..) (Daniel P. Berrangé <berrange@redhat.com> and Marc-André Lureau <marcandre.lureau@redhat.com>) removed 'dpy_gl' from all helpers' names Defined autoptr clean up function for QemuDmaBuf* (Daniel P. Berrangé <berrange@redhat.com>) Minor corrections v8: Introduce new dmabuf.c and dmabuf.h and all helper functions in the second patch in the series (ui/console: new dmabuf.h and dmabuf.c for QemuDma....) (Philippe Mathieu-Daudé <philmd@linaro.org>) v9: set dmabuf->allow_fences true when it is created in virtio-gpu-udmabuf removed unnecessary spaces were added in the patch, 'ui/console: Use qemu_dmabuf_new() a...' v10: Change the license type for both dmabuf.h and dmabuf.c from MIT to GPL to be in line with QEMU's default license (Daniel P. Berrangé <berrange@redhat.com>) v11: New helpers added - qemu_dmabuf_dup_fd, qemu_dmabuf_close for duplicating and closing dmabuf->fd. And use them in places where applicable. (Daniel P. Berrangé <berrange@redhat.com>) qemu_dmabuf_free helper now close dmabuf->fd before freeing the struct to prevent any potential leakage (This eliminates the need for qemu_dmabuf_close in several places as qemu_dmabuf_close is done anyway.) (Daniel P. Berrangé <berrange@redhat.com>) v12: --- qemu_dmabuf_free does not include qemu_dmabuf_close as there are cases where fd still needs to be used even after QemuDmaBuf struct is destroyed (virtio-gpu: res->dmabuf_fd) --- 'dmabuf' is now allocated space so it should be freed at the end of dbus_scanout_texture Dongwon Kim (6): ui/gtk: Check if fence_fd is equal to or greater than 0 ui/console: new dmabuf.h and dmabuf.c for QemuDmaBuf struct and helpers ui/console: Use qemu_dmabuf_get_..() helpers instead ui/console: Use qemu_dmabuf_set_..() helpers instead ui/console: Use qemu_dmabuf_new() and free() helpers instead ui/console: move QemuDmaBuf struct def to dmabuf.c include/hw/vfio/vfio-common.h | 2 +- include/hw/virtio/virtio-gpu.h | 4 +- include/ui/console.h | 20 +-- include/ui/dmabuf.h | 49 +++++++ hw/display/vhost-user-gpu.c | 26 ++-- hw/display/virtio-gpu-udmabuf.c | 27 ++-- hw/vfio/display.c | 32 ++--- ui/console.c | 4 +- ui/dbus-console.c | 9 +- ui/dbus-listener.c | 72 +++++----- ui/dmabuf.c | 229 ++++++++++++++++++++++++++++++++ ui/egl-headless.c | 23 +++- ui/egl-helpers.c | 59 ++++---- ui/gtk-egl.c | 52 +++++--- ui/gtk-gl-area.c | 41 ++++-- ui/gtk.c | 12 +- ui/spice-display.c | 50 ++++--- ui/meson.build | 1 + 18 files changed, 519 insertions(+), 193 deletions(-) create mode 100644 include/ui/dmabuf.h create mode 100644 ui/dmabuf.c
