Description

The ipopts keyword may be misfiring.

https://forum.suricata.io/t/suricata-cant-define-ip-options/4494/7 describes a situation where the OP requested an alert when strict source route occurs but found that the rule was creating an alert with a packet having the stream id IP option.

The rule used by the OP:

alert ip any any -> any any (ipopts: ssrr; msg: "issue"; rev: 1; sid:1;)
