Thomas Zimmermann 2712ca878b Revert "drm/gem-framebuffer: Use dma_buf from GEM object instance" ... This reverts commit cce16fcd74. The dma_buf field in struct drm_gem_object is not stable over the object instance's lifetime. The field becomes NULL when user space releases the final GEM handle on the buffer object. This resulted in a NULL-pointer deref. Workarounds in commit 5307dce878 ("drm/gem: Acquire references on GEM handles for framebuffers") and commit f6bfc9afc7 ("drm/framebuffer: Acquire internal references on GEM handles") only solved the problem partially. They especially don't work for buffer objects without a DRM framebuffer associated. Hence, this revert to going back to using .import_attach->dmabuf. v3: - cc stable Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Simona Vetter <simona.vetter@ffwll.ch> Acked-by: Christian König <christian.koenig@amd.com> Acked-by: Zack Rusin <zack.rusin@broadcom.com> Cc: <stable@vger.kernel.org> # v6.15+ Link: https://lore.kernel.org/r/20250715155934.150656-6-tzimmermann@suse.de		2025-07-17 12:26:19 +02:00
