Dear Andreas,

Is there a way to provoke such an error, so we can test this?

Patch rejected. What happens if "len" turns out to be zero?
Also, the code is unnecessary complex.

If there really is such a problem, this should do as well (and  maybe
better):

	printf ("\nTFTP error: '%.*s' (%d)\n",
		len - 2,
		pkt + 2,
		ntohs(*(ushort *)pkt) );

Can you please test this (and eventually re-submit the patch) ?

Thanks.

Best regards,

Wolfgang Denk
