Jimmy Jones created BIT-1246:

             Summary: Missing last TCP segment
                 Key: BIT-1246
                 URL: https://bro-tracker.atlassian.net/browse/BIT-1246
             Project: Bro Issue Tracker
          Issue Type: Problem
          Components: Bro
    Affects Versions: 2.3, git/master
         Environment: CentOS 6
            Reporter: Jimmy Jones
         Attachments: get-hole2.trace

Possibly related to BIT-1240, I've got a sample (attached) where the penultimate TCP segment of the http response is missing.

Using the file analysis framework I'm extracting the payload, but I don't get any of the last segment. Without the fix in BIT-1240 additionally the NULL padding for the missing packets happens in the wrong place.

Used the following bro script:

event file_new(f: fa_file)
{ Files::add_analyzer(f, Files::ANALYZER_EXTRACT, [$extract_filename=f$id]); }
