             Summary: topic/jsiwek/dns-improvements
                 Key: BIT-1122
                 URL: https://bro-tracker.atlassian.net/browse/BIT-1122
             Project: Bro Issue Tracker
          Issue Type: Problem
          Components: Bro
    Affects Versions: git/master
            Reporter: Jon Siwek
             Fix For: 2.3

This branch is in bro, bro-testing, and bro-testing-private repos.

- Fixes incorrect parsing of DNS message format for messages with empty question sections.
- Changes dns.log to only include standard queries (opcode == 1).
- Adds "dns_unknown_reply" event for RR types that Bro doesn't know how to parse, which improves accuracy of request-reply pair matching performed by the default DNS scripts.
