+	* resolv/res_send.c (__libc_res_nsend): Take additional parameter.
+	Use it instead of locally defined resplen2 variable.
+	(res_nsend): Adjust for __libc_res_nsend interface change.
+	(send_vc): Initialize *resplen2 if necessary.  Read length of
+	package into an appropriately aligned variable.  Store converted length
+	in new variable and use it appropriately.
+	Add branch prediction help.
+	* resolv/res_query.c (__libc_res_nquery): Take additional parameter
+	and pass it on to __libc_res_nsend.  Adjust all callers.
+	(__libc_res_nsearch): Likewise.
+	(__libc_res_nqeurydomain): Likewise.

+	change.
+	(_nss_dns_gethostbyname4): Don't unconditionally allocate tmp array.
+	Define resplen2 variable and pass it to __libc_res_nsearch and then
+	to gaih_getanswer.
+	(getanswer_r): In case of incorrect DNS data don't overread buffer.
+	Add branch prediction.
+	(gaih_getanswer_slice): Likewise.  Check for invalid data types.
+	(gaih_getanswer): Don't decode second slice if first one failed due
+	to a too small buffer.  Don't let not found status of second
+	decoder shadow results of the first.
