From: Emil Velikov Date: Mon, 27 May 2019 08:17:37 +0000 (+0100) Subject: drm/omap: drop DRM_AUTH from DRM_RENDER_ALLOW ioctls X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7042a33deb1411523c88e98d8e79ac7399fdee4c;p=openwrt%2Fstaging%2Fblogic.git drm/omap: drop DRM_AUTH from DRM_RENDER_ALLOW ioctls The authentication can be circumvented, by design, by using the render node. From the driver POV there is no distinction between primary and render nodes, thus we can drop the token. Note: the outstanding DRM_AUTH instance is: - (badly coped) legacy DRI1 ioctl, which is a noop Cc: Tomi Valkeinen Cc: David Airlie Cc: Daniel Vetter Signed-off-by: Emil Velikov Acked-by: Tomi Valkeinen Link: https://patchwork.freedesktop.org/patch/msgid/20190527081741.14235-9-emil.l.velikov@gmail.com --- diff --git a/drivers/gpu/drm/omapdrm/omap_drv.c b/drivers/gpu/drm/omapdrm/omap_drv.c index 5929f8688e5a..7bd2da5eb1ce 100644 --- a/drivers/gpu/drm/omapdrm/omap_drv.c +++ b/drivers/gpu/drm/omapdrm/omap_drv.c @@ -477,19 +477,19 @@ static int ioctl_gem_info(struct drm_device *dev, void *data, static const struct drm_ioctl_desc ioctls[DRM_COMMAND_END - DRM_COMMAND_BASE] = { DRM_IOCTL_DEF_DRV(OMAP_GET_PARAM, ioctl_get_param, - DRM_AUTH | DRM_RENDER_ALLOW), + DRM_RENDER_ALLOW), DRM_IOCTL_DEF_DRV(OMAP_SET_PARAM, drm_invalid_op, DRM_AUTH | DRM_MASTER | DRM_ROOT_ONLY), DRM_IOCTL_DEF_DRV(OMAP_GEM_NEW, ioctl_gem_new, - DRM_AUTH | DRM_RENDER_ALLOW), + DRM_RENDER_ALLOW), /* Deprecated, to be removed. */ DRM_IOCTL_DEF_DRV(OMAP_GEM_CPU_PREP, drm_noop, - DRM_AUTH | DRM_RENDER_ALLOW), + DRM_RENDER_ALLOW), /* Deprecated, to be removed. */ DRM_IOCTL_DEF_DRV(OMAP_GEM_CPU_FINI, drm_noop, - DRM_AUTH | DRM_RENDER_ALLOW), + DRM_RENDER_ALLOW), DRM_IOCTL_DEF_DRV(OMAP_GEM_INFO, ioctl_gem_info, - DRM_AUTH | DRM_RENDER_ALLOW), + DRM_RENDER_ALLOW), }; /*
