Before this commit, nss_dns would send a query which did not contain a host name as the query name (such as invalid\032name.example.com) and then reject the answer in getanswer_r and gaih_getanswer_slice, using a check based on res_hnok. With this commit, no query is sent, and a host-not-found error is returned to NSS without network interaction. |
