FTP response buffering against TCP stream

Status:
Closed
Priority:
Normal
Assignee:

Target version:
6.0.0beta1
Affected Versions:
4.1.6, 5.0.1

Difficulty:
Label:
Needs backport to 4.1, Needs backport to 5.0

Description

Now, Suricata parses FTP response packets as if they are always complete.
This is not the TCP logic of streaming.
We have to keep buffering until the response is complete, and we can parse multiple responses in one TCP stream in one time.

Found by running suricata-verify tests while doing TCP stream splitting

Fix proposed https://github.com/OISF/suricata/pull/4789
