From: Mateusz Polrola <mateuszx.potrola at intel.com>

With earlier implementation memory for NULL byte of l->filename string
was not being allocated by malloc (strlen is returning length of string
without NULL terminating byte) which may result in some random
characters appended in filename string.
Now strdup is begin used for string copy instead of malloc/strcpy.
