* drm: Fix authentication kernel crashThomas Hellstrom2012-02-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | commit 598781d71119827b454fd75d46f84755bca6f0c6 upstream. If the master tries to authenticate a client using drm_authmagic and that client has already closed its drm file descriptor, either wilfully or because it was terminated, the call to drm_authmagic will dereference a stale pointer into kmalloc'ed memory and corrupt it. Typically this results in a hard system hang. This patch fixes that problem by removing any authentication tokens (struct drm_magic_entry) open for a file descriptor when that file descriptor is closed.

* drm: integer overflow in drm_mode_dirtyfb_ioctl()Xi Wang2011-12-091-0/+2
| | | | | | | | | | | | | | | commit a5cd335165e31db9dbab636fd29895d41da55dd2 upstream. There is a potential integer overflow in drm_mode_dirtyfb_ioctl() if userspace passes in a large num_clips. The call to kmalloc would allocate a small buffer, and the call to fb->funcs->dirty may result in a memory corruption.

* drm/i915: Fix typo in DRM_I915_OVERLAY_PUT_IMAGE ioctl defineOle Henrik Jahren2011-08-151-1/+1
| | | | | | | | | | | | | | | | | commit 842d452985300f4ec14c68cb86046e8a1a3b7251 upstream. Because of a typo, calling ioctl with DRM_IOCTL_I915_OVERLAY_PUT_IMAGE is broken if the macro is used directly. When using libdrm the bug is not hit, since libdrm handles the ioctl encoding internally. The typo also leads to the .cmd and .cmd_drv fields of the drm_ioctl structure for DRM_I915_OVERLAY_PUT_IMAGE having inconsistent content.

* drm: Separate EDID Header Check from EDID Block CheckThomas Reim2011-08-151-0/+1
| | | | | | | | | | | | | | | | | | | commit 051963d4832ed61e5ae74f5330b0a94489e101b9 upstream. Provides function drm_edid_header_is_valid() for EDID header check and replaces EDID header check part of function drm_edid_block_valid() by a call of drm_edid_header_is_valid(). This is a prerequisite to extend DDC probing, e. g. in function radeon_ddc_probe() for Radeon devices, by a central EDID header check.

* drm/radeon: workaround a hw bug on some radeon chipsets with all-0 EDIDs.Dave Airlie2011-06-161-0/+2
| | | | | | | | | | | | | | | Some RS690 chipsets seem to end up with floating connectors, either a DVI connector isn't actually populated, or an add-in HDMI card is available but not installed. In this case we seem to get a NULL byte response for each byte of the i2c transaction, so we detect this case and if we see it we don't do anymore DDC transactions on this connector. I've tested this on my RS690 without the HDMI card installed and it seems to work fine. Signed-off-by: Dave Airlie <airlied@redhat.com> Reviewed-by: Alex Deucher <alexdeucher@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | Below is a patch against drm-next branch of 2.6.38-rc8+ kernel that adds the capability to wait on vblank events for CRTCs that are greater than 1 and thus cannot be represented with primary/secondary flags in the legacy interface. It was discussed on the dri-devel list in these two threads: http://lists.freedesktop.org/archives/dri-devel/2011-March/009009.html http://lists.freedesktop.org/archives/dri-devel/2011-March/009025.html This patch extends the interface to drm_wait_vblank ioctl so that crtc>1 can be represented. It also adds a new capability to drm_getcap ioctl so that the user space can check whether the new interface to drm_wait_vblank is supported (and fall back to the legacy interface if not) Signed-off-by: Ilija Hadzic <ihadzic@research.bell-labs.com> Reviewed-by: Mario Kleiner <mario.kleiner at tuebingen.mpg.de> Acked-by: Mario Kleiner <mario.kleiner at tuebingen.mpg.de> Reviewed-by: Alex Deucher <alexdeucher@gmail.com> Tested-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old api has a two-step process: First search for a suitable free hole, then allocate from that specific hole. No user used this to do anything clever. So drop it for the embeddable variant of the drm_mm api (the old one retains this ability, for the time being). With struct drm_mm_node embedded, we cannot track allocations anymore by checking for a NULL pointer. So keep track of this and add a small helper drm_mm_node_allocated. Also add a function to move allocations between different struct drm_mm_node. v2: Implement suggestions by Chris Wilson.

To avoid an ugly corner case add a dummy head_node to struct drm_mm to track the hole that spans to complete allocation area when the memory manager is empty. To guarantee that there's always a preceeding/following node (that might be marked as hole_follows == 1), move the mm->node_list list_head to the head_node. The main allocator and fair-lru scan code actually becomes simpler. Only the debug code slightly suffers because free areas are no longer explicit. Also add drm_mm_for_each_node (which will be much more useful when struct drm_mm_node is embeddable).
