In fctx_query(), resquery_ref(query) is called before dns_dispatch_connect() in anticipation of the resquery_connected() callback consuming the reference. When dns_dispatch_connect() fails synchronously on TCP (e.g. from dns_transport_get_tlsctx() failing in tcp_dispatch_connect()), the connect callback is never scheduled, so the extra reference is never consumed. The error path then tears down the query via manual cleanup (isc_mem_put) without going through the refcount destructor, leaving the reference imbalanced. Fix by dropping the extra reference on the error path, just after dns_dispatch_done() which cleans up the dispatch entry. |
