Comment # 1 on bug 9749 from 
Hi Antonio,

Wireshark only follow the RFC about length :

For UDP (RFC768)

Length is the length  in octets  of this user datagram  including  this
header  and the data.   (This  means  the minimum value of the length is
eight.)

For TCP (RFC793)
The TCP Length is the TCP header length plus the data length in octets (this is
not an explicitly transmitted quantity, but is computed), and it does not count
the 12 octets of the pseudo header.

But may be add udp.data_len field (udp.len - 8) with generated flag
