Hi. On a 32-bit system the display filter "tcp.len < -1" seems to be valid, and does return all TCP packets.
This happens because we use strtoul() to convert the string "-1" to a unsigned long, and the documentation states that "the string is converted to an unsigned long value in the obvious manner". I suppose this means that the value is casted from signed to unsigned without a warning. The attached patch fixes this, but can we do this check in a simpler manner? -- Stig Bjørlykke
