I'll push 3 patches to master, after make test is finished.

I think this is wrong as cname is maybe the talloc chunk with the scope
at the end, but with a \0 in the middle. We should not expose such a
string to the caller, as the caller may want to use
talloc_*_append_buffer().

-	r->name = talloc_strdup(ndr->current_mem_ctx, cname);
-	NDR_ERR_HAVE_NO_MEMORY(r->name);
-
-	talloc_free(cname);
+	r->name = talloc_steal(ndr->current_mem_ctx, cname);
