resolv/nss_dns : dns-host.c
Log message:
Adjust for __libc_res_nsearch interface 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.
