Merge tag 'drm-misc-next-2019-05-24' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

2019-05-27T22:59:11+00:00

drm-misc-next for v5.3, try #2: UAPI Changes: - Add HDR source metadata property. - Make drm.h compile on GNU/kFreeBSD by including stdint.h - Clarify how the userspace reviewer has to review new kernel UAPI. - Clarify that for using new UAPI, merging to drm-next or drm-misc-next should be enough. Cross-subsystem Changes: - video/hdmi: Add unpack function for DRM infoframes. - Device tree bindings: * Updating a property for Mali Midgard GPUs * Updating a property for STM32 DSI panel * Adding support for FriendlyELEC HD702E 800x1280 panel * Adding support for Evervision VGG804821 800x480 5.0" WVGA TFT panel * Adding support for the EDT ET035012DM6 3.5" 320x240 QVGA 24-bit RGB TFT. * Adding support for Three Five displays TFC S9700RTWV43TR-01B 800x480 panel with resistive touch found on TI's AM335X-EVM. * Adding support for EDT ETM0430G0DH6 480x272 panel. - Add OSD101T2587-53TS driver with DT bindings. - Add Samsung S6E63M0 panel driver with DT bindings. - Add VXT VL050-8048NT-C01 800x480 panel with DT bindings. - Dma-buf: - Make mmap callback actually optional. - Documentation updates. - Fix debugfs refcount inbalance. - Remove unused sync_dump function. - Fix device tree bindings in drm-misc-next after a botched merge. Core Changes: - Add support for HDR infoframes and related EDID parsing. - Remove prime sg_table caching, now done inside dma-buf. - Add shiny new drm_gem_vram helpers for simple VRAM drivers; with some fixes to the new API on top. - Small fix to job cleanup without timeout handler. - Documentation fixes to drm_fourcc. - Replace lookups of drm_format with struct drm_format_info; remove functions that become obsolete by this conversion. - Remove double include in bridge/panel.c and some drivers. - Remove drmP.h include from drm/edid and drm/dp. - Fix null pointer deref in drm_fb_helper_hotplug_event(). - Remove most members from drm_fb_helper_crtc, only mode_set is kept. - Remove race of fb helpers with userspace; only restore mode when userspace is not master. - Move legacy setup from drm_file.c to drm_legacy_misc.c - Rework scheduler job destruction. - drm/bus was removed, remove from TODO. - Add __drm_atomic_helper_crtc_reset() to subclass crtc_state, and convert some drivers to use it (conversion is not complete yet). - Bump vblank timeout wait to 100 ms for atomic. - Docbook fix for drm_hdmi_infoframe_set_hdr_metadata. Driver Changes: - sun4i: Use DRM_GEM_CMA_VMAP_DRIVER_OPS instead of definining manually. - v3d: Small cleanups, adding support for compute shaders, reservation/synchronization fixes and job management refactoring, fixes MMU and debugfs. - lima: Fix null pointer in irq handler on startup, set default timeout for scheduled jobs. - stm/ltdc: Assorted fixes and adding FB modifier support. - amdgpu: Avoid hw reset if guilty job was already signaled. - virtio: Add seqno to fences, add trace events, use correct flags for fence allocation. - Convert AST, bochs, mgag200, vboxvideo, hisilicon to the new drm_gem_vram API. - sun6i_mipi_dsi: Support DSI GENERIC_SHORT_WRITE_2 transfers. - bochs: Small fix to use PTR_RET_OR_ZERO and driver unload. - gma500: header fixes - cirrus: Remove unused files. - mediatek: Fix compiler warning after merging the HDR series. - vc4: Rework binner bo handling.

drm/edid: Fix a missing-check bug in drm_load_edid_firmware()

2019-05-24T18:01:33+00:00

In drm_load_edid_firmware(), fwstr is allocated by kstrdup(). And fwstr is dereferenced in the following codes. However, memory allocation functions such as kstrdup() may fail and returns NULL. Dereferencing this null pointer may cause the kernel go wrong. Thus we should check this kstrdup() operation. Further, if kstrdup() returns NULL, we should return ERR_PTR(-ENOMEM) to the caller site.
