Description

I run Suricata on MacOS:

# suricata -i en6 -F filter.bpf -v

filter.bpf limits the traffic to a single IP address:

host 192.168.1.19

fast.log shows an alert:

04/06/2022-11:45:39.142492 [**] [1:2260002:1] SURICATA Applayer Detect protocol only one direction [**] [Classification: Generic Protocol Command Decode] [Priority: 3] {TCP} 192.168.1.19:64527 -> 192.168.1.178:7000

However, the traffic contains both directions. See attached PCAP.

I have reported this issue at forum.suricata.io (https://forum.suricata.io/t/applayer-detect-protocol-only-one-direction/2371/2) and Andrea Herz was able to reproduce it.
