Description

There is a pcap that cannot trigger filestore.

Note: turn on midstream when retesting.

I think the ASYN responses header is what is causing the problem.

I do not reproduce the problem on latest master :

./src/suricata -l log -k none -r /Users/catena/Downloads/smb_store_error.pcap -c suricata.yaml --set stream.midstream=true --set vlan.use-for-tracking=false --set outputs.0.file-store.enabled=yes -S smb.rules

with smb.rules being alert smb any any -> any any (msg:"test filestore required"; filestore; sid:10; rev:1;)

Then
find log/filestore/ -type f gives me log/filestore//d5/d50ea1b6b3e8ed084afc47537dd3dc0a5397d7f57595a9268c56c80e88095eee

Did you --set vlan.use-for-tracking=false and enable filestore output ?

Working as expected with --set vlan.use-for-tracking=false
