I'm generating packets on an arm (aarch64) processor running trafgen 0.6.6+
and when it should send a packet with UDP checksum 0xffff, it sends 0x0000.
Here is the config:
# cat inc-dport.config
cpu(1): {
eth(daddr=00:01:02:03:04:05),
ipv4(daddr=172.16.0.5, proto=17),
udp(dport=dinc()),
fill(0xaa, 128)
}
And here is an example of a bad checksum packet (from netsniff-ng):
< ? 170 4529s.815007000ns #195611
[ tpacketv3 VLAN Prio (0), CFI (0), ID (0), Proto (0x0000) ]
[ Eth MAC (00:01:02:03:04:06 => 00:01:02:03:04:05), Proto (0x0800, IPv4) ]
[ Vendor (3COM CORPORATION => 3COM CORPORATION) ]
[ IPv4 Addr (172.16.0.6 => 172.16.0.5), Proto (17), TTL (0), TOS (0), Ver

FragOff (0), CSum (0x6226) is ok ]
[ UDP Port (0 => 64519), Len (136 Bytes, 128 Bytes Data), CSum (0x0000) ]
