If you do a page flip with no flags set then event is NULL. If event is NULL then the vmw_gfx driver likes to go digging into NULL and extracts NULL->base.file_priv. On a modern kernel with NULL mapping protection it's just another oops, without it there are some "intriguing" possibilities. What it should do is an open question but that for the driver owners to sort out.

The assignment of handle in vmw_framebuffer_create_handle doesn't actually do anything useful and is incorrectly assigning an integer value to a pointer argument. It appears that this is a typo and should be dereferencing handle rather than assigning to it directly. This fixes a bug where an undefined handle value is potentially returned to user-space.

Commit e133e737 didn't correctly fix the integer overflow issue. - unsigned int required_size; + u64 required_size; ... required_size = mode_cmd->pitch * mode_cmd->height; - if (unlikely(required_size > dev_priv->vram_size)) { + if (unlikely(required_size > (u64) dev_priv->vram_size)) { Note that both pitch and height are u32. Their product is still u32 and would overflow before being assigned to required_size. A correct way is to convert pitch and height to u64 before the multiplication. required_size = (u64)mode_cmd->pitch * (u64)mode_cmd->height; This patch calls the existing vmw_kms_validate_mode_vram() for validation.

Otherwise each driver would need to keep the information inside their own framebuffer object structure. Also add offsets[]. BOs on the other hand are driver specific, so those can be kept in driver specific structures.

There are two issues in vmw_kms_update_layout_ioctl(). First, the for loop forgets to index rects and only checks the first element. Second, there is a potential integer overflow if userspace passes in a large arg->num_outputs. The call to kzalloc() would allocate a small buffer, leading to out-of-bounds read.

To properly support the various plane formats supported by different hardware, the kernel must know the pixel format of a framebuffer object. So add a new ioctl taking a format argument corresponding to a fourcc name from the new drm_fourcc.h header file. Implement the fb creation hooks in terms of the new mode_fb_cmd2 using helpers where the old bpp/depth values are needed. v2: create DRM specific fourcc header file for sharing with libdrm etc v3: fix rebase failure and use DRM fourcc codes in intel_display.c and update commit message v4: make fb_cmd2 handle field into an array for multi-object formats pull in Ville's fix for the memcpy in drm_plane_init apply Ville's cleanup to zero out fb_cmd2 arg in drm_mode_addfb v5: add 'flags' field for interlaced support (from Ville) Signed-off-by: NVille Syrjälä <ville.syrjala@linux.intel.com> Acked-by: NAlan Cox <alan@lxorguk.ukuu.org.uk> Reviewed-by: NRob Clark <rob.clark@linaro.org> Signed-off-by: NJesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: NDave Airlie <airlied@redhat.com>

We need to redefine a connector as "connected" if it matches a window in the host preferred GUI layout. Otherwise "smart" window managers would turn on Xorg outputs that we don't want to be on. This reinstates the update_layout and adds the following information to the modesetting system. a) Connection status <-> Equivalent to real hardware connection status b) Preferred mode <-> Equivalent to real hardware reading EDID c) Host window position <-> Equivalent to a real hardware scanout address dynamic register. It should be noted that there is no assumption here about what should be displayed and where. Only how to access the host windows. This also bumps minor to signal availability of the new IOCTL.
