For example, test case 152 has an IPID of 21152 with scenario 21 and 36152 for scenarii 36.=20 (2) These IPIDs are, however, repeated across the runs. For the other tested IPv4 and IPv6 targets, we do not usually reboot the target between the runs, since we do not observe inconsistent test case reassemblies. However, after= the FreeBSD host reboot (which should discard any previously received fragments, right?), we still observe inconsistent reassemblies.=20 You can find here https://filesender.renater.fr/?s=3Ddownload&token=3D5f407a38-1bc5-47db-aeef= -cce91bdabc73 a minimal version of our testing tool with two testing scenarii for which w= e've found inconsistencies across our runs, namely peoef and peosp-nf. I prepared some instructions in the README, but you might need additional ones. Do not hesitate if you need anything. --=20 You are receiving this mail because: You are the assignee for the bug.=
