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