Changes during merge - Changed the policy script to use an event handler that behaves for like the base script: &priority=5, msg$opcode != early-out, no record field existence checks - Also extended dns_query_reply event with original_query param - Removed ExtractName overload, and just use default param * 'dns-original-query-case' of https://github.com/rvictory/zeek: Fixed some places where tabs became spaces Stricter checking if we have a dns field on the connection being processed Modified the DNS protocol analyzer to add a new parameter to the dns_request event which includes the DNS query in its original case. Added a policy script that will add the original_case to the dns.log file as well. Created new btests to test both.
