   4 Subject: [PATCH] inet: do not filter responses in res_query
   5 MIME-Version: 1.0
   6 Content-Type: text/plain; charset=UTF-8
   7 Content-Transfer-Encoding: 8bit
   8
   9 Fixes bug #5342
  10
  11 res_query was silently rejecting responses against T_ANY DNS
  12 questions.
  13
  14 Remove the type-filtering from res_query altogether.
  15 __dns_lookup is supposed to return the proper stuff that you asked
  16 for (and only that).
