Description

Currently signature using ip and tcp and using a file keyword like filemd5 are not valid in the sense they will not match:

alert ip any any -> any any (msg:"guess what"; filemd5:test.md5; sid: 1; rev: 1;)
alert tcp any any -> any any (msg:"guess what"; filemd5:test.md5; sid: 2; rev: 1;)

But Suricata does not complain about it.
