Thomas Zimmermann 8260731cca drm/gem: Internally test import_attach for imported objects ... Test struct drm_gem_object.import_attach to detect imported objects. During object clenanup, the dma_buf field might be NULL. Testing it in an object's free callback then incorrectly does a cleanup as for native objects. Happens for calls to drm_mode_destroy_dumb_ioctl() that clears the dma_buf field in drm_gem_object_exported_dma_buf_free(). v3: - only test for import_attach (Boris) v2: - use import_attach.dmabuf instead of dma_buf (Christian) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Fixes: b57aa47d39 ("drm/gem: Test for imported GEM buffers with helper") Reported-by: Andy Yan <andyshrk@163.com> Closes: https://lore.kernel.org/dri-devel/38d09d34.4354.196379aa560.Coremail.andyshrk@163.com/ Tested-by: Andy Yan <andyshrk@163.com> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: Anusha Srivatsa <asrivats@redhat.com> Cc: Christian König <christian.koenig@amd.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <mripard@kernel.org> Cc: David Airlie <airlied@gmail.com> Cc: Simona Vetter <simona@ffwll.ch> Cc: Sumit Semwal <sumit.semwal@linaro.org> Cc: "Christian König" <christian.koenig@amd.com> Cc: dri-devel@lists.freedesktop.org Cc: linux-media@vger.kernel.org Cc: linaro-mm-sig@lists.linaro.org Reviewed-by: Boris Brezillon <boris.brezillon@collabora.com> Reviewed-by: Simona Vetter <simona.vetter@ffwll.ch> Link: https://lore.kernel.org/r/20250416065820.26076-1-tzimmermann@suse.de		2025-04-17 09:52:48 +02:00
