      staging/lustre: remove IOC_LIBCFS_PING_TEST ioctl · d035e336
      James Simmons authored
      The ioctl IOC_LIBCFS_PING_TEST has not been used in ages.  The recent
      nidstring changes which moved all the nidstring operations from libcfs
      to the LNet layer but this ioctl code was still using an nidstring
      operation that was causing a circular dependency loop between libcfs and
      LNet.

       "A couple of fixes (-stable fodder) + dead code removal after the
        overlayfs fix.
      
        I agree that it's better to separate from the fix part to make
        backporting easier, but IMO it's not worth delaying said dead code
        removal until the next window"

      Don't reset ->total_link_count on nested calls of vfs_path_lookup() · 2788cc47
      Al Viro authored
      we already zero it on outermost set_nameidata(), so initialization in
      path_init() is pointless and wrong.  The same DoS exists on pre-4.2
      kernels, but there a slightly different fix will be needed.

      ovl: fix permission checking for setattr · acff81ec
      Miklos Szeredi authored
      [Al Viro] The bug is in being too enthusiastic about optimizing ->setattr()
      away - instead of "copy verbatim with metadata" + "chmod/chown/utimes"
      (with the former being always safe and the latter failing in case of
      insufficient permissions) it tries to combine these two.  Note that copyup
      itself will have to do ->setattr() anyway; _that_ is where the elevated
      capabilities are right.  Having these two ->setattr() (one to set verbatim
      copy of metadata, another to do what overlayfs ->setattr() had been asked
      to do in the first place) combined is where it breaks.

        with how we pass the drm master around.
      
        The rest is just some amdgpu, i915, imx and rockchip fixes.
