* resolv/res_send.c (__libc_res_nsend): Take additional parameter.cvs/fedora-glibc-20080728T2320
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. * resolv/nss_dns/dns-host.c: 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. * resolv/gethnamaddr.c (gethostbyname2): Adjust for __libc_res_nsearch and __libc_res_nquery interface changes (gethostbyaddr): Adjust for __libc_res_nquery interface change. * include/resolv.h: Adjust prototypes for __libc_res_nquery, __libc_res_nsearch, and __libc_res_nsend. * resolv/nss_dns/dns-canon.c: Adjust for __libc_res_nquery interface change. * resolv/nss_dns/dns-network.c: Adjust for __libc_res_nquery and __libc_res_nsearch interface changes.
