      drm: use noop_llseek · dc880abe
      Arnd Bergmann 提交于
      The drm device drivers currently allow seeking on the
      character device but never care about the actual
      file position.
      
      When we change the default llseek operation to be
      no_llseek, calling llseek on a drm device would
      return an error condition, which is an API change.
      
      Explicitly setting noop_llseek lets us keep the
      current API.

      drm: block userspace under allocating buffer and having drivers overwrite it (v2) · 1b2f1489
      Dave Airlie 提交于
      With the current screwed but its ABI, ioctls for the drm, Linus pointed out that we could allow userspace to specify the allocation size, but we pass it to the driver which then uses it blindly to store a struct. Now if userspace specifies the allocation size as smaller than the driver needs, the driver can possibly overwrite memory.
      
      This patch restructures the driver ioctls so we store the structure size we are expecting, and make sure we allocate at least that size. The copy from/to userspace are still restricted to the size the user specifies, this allows ioctl structs to grow on both sides of the equation.
      
      Up until now we didn't really use the DRM_IOCTL defines in the kernel, so this cleans them up and adds them for nouveau.
      
      v2:
      fix nouveau pushbuf arg (thanks to Ben for pointing it out)
