For UDP the send socket was changed from SOCK_DGRAM to SOCK_RAW and thus the UDP checksum need be calculated by application itself other than the kernel. outpacket is filled with zeros by line 707, thus the first round the UDP checksum is correct. But subsequent rounds outudp->uh_sum will be left with garbage.
