Bug Description
When the --icmp-ipid option is used to set the identifier field in the ICMP echo request, the corresponding echo reply packet is ignored. I have verified this behavior with tcpdump -- the packets do indeed arrive, but they are not recorded:
$ sudo hping3 -1 --icmp-ipid 256 8.8.8.8
HPING 8.8.8.8 (eth0 8.8.8.8): icmp mode set, 28 headers + 0 data bytes
^C
--- 8.8.8.8 hping statistic ---
4 packets transmitted, 0 packets received, 100% packet loss
round-trip min/avg/max = 0.0/0.0/0.0 ms
Patch to follow. With the patch:
$ sudo hping3 -1 --icmp-ipid 256 8.8.8.8
HPING 8.8.8.8 (eth0 8.8.8.8): icmp mode set, 28 headers + 0 data bytes
