gethstbynm3_r. * nscd/gethstbynm2_r.c: Remove. * nscd/gethstbynm3_r.c: New file. * nscd/aicache.c (addhstaiX): Use __gethostbyaddr2_r instead of __gethostbyaddr_r. * nscd/gethstbyad_r.c: Generate __gethostbyaddr2_r function. Define __gethostbyaddr_r compatibility wrapper. * nscd/hstcache.c (cache_addhst): Add ttl parameter. Use it when determining timeout of entry. (lookup): Take new parameter and pass it to __gethostbyname3_r and __gethostbyaddr2_r. (addhstbyX): Pass reference to variable for TTL to lookup and cache_addhst. * nss/Versions [glibc] (GLIBC_PRIVATE): Export __nss_passwd_lookup2, __nss_group_lookup2, __nss_hosts_lookup2, __nss_services_lookup2, and __nss_next2. Remove __nss_services_lookup. * nss/XXX-lookup.c: Name function now *_lookup2. Add new parameter. Add compat wrapper. * nss/getXXbyYY_r.c: Changes to call new *_lookup2 functions and __nss_next2. * nss/getXXent_r.c: Likewise. * nss/getnssent_r.c: Likewise. * nss/nsswitch.c (__nss_lookup): Add new parameter. If first function does not exist in module, try the optional second name. (__nss_next2): New function. (__nss_next): Now wrapper around __nss_next2. * nss/nsswitch.h: Adjust __nss_lookup prototype. Declare __nss_next2. Adjust definition of db_lookup_function type. * nss/service-lookup.c: Define NO_COMPAT. * include/netdb.h: Declare __gethostbyaddr2_r and __gethostbyname3_r. * inet/ether_hton.c: Use __nss_next2 instead of __nss_next. * inet/ether_ntoh.c: Likewise. * sunrpc/netname.c: Likewise. * sunrpc/publickey.c: Likewise. * inet/getnetgrent.c: Likewise. Adjust calls to __nss_lookup. * inet/gethstbyad_r.c (DB_LOOKUP_FCT): Change to __nss_hosts_lookup2. * inet/gethstbynm2_r.c (DB_LOOKUP_FCT): Likewise. * inet/gethstbynm_r.c (DB_LOOKUP_FCT): Likewise. * inet/gethstent_r.c (DB_LOOKUP_FCT): Likewise. * nscd/aicache.c (addhstaiX): Fix default TTL handling. * inet/getnetgrent.c (setup): Encrypt static pointer.
