           completely. With 'nosmt' being a popular option it's required to

      Rasmus Villemoes authored
      If userspace doesn't end the input with a newline (which can easily
      happen if the write happens from a C program that does write(fd,
      iface, strlen(iface))), we may end up including garbage from a
      previous, longer value in the device_name. For example
      
      # cat device_name
      
      # printf 'eth12' > device_name
      # cat device_name
      eth12
      # printf 'eth3' > device_name
      # cat device_name
      eth32
      
      I highly doubt anybody is relying on this behaviour, so switch to
      simply copying the bytes (we've already checked that size is <
      IFNAMSIZ) and unconditionally zero-terminate it; of course, we also
      still have to strip a trailing newline.
      
      This is also preparation for future patches.
