Update.
2000-07-18 Mark Kettenis <kettenis@gnu.org> Update resolver code to BIND 8.2.3-T5B. * resolv/Versions [GLIBC_2.2] (libc): Add __res_init and __res_nclose. [GLIBC_2.2] (libresolv): Add __dn_expand, __ns_samename, __res_mkquery, __res_nsend, __res_query, __res_querydomain and __res_search. * resolv/Banner: BIND-8.2.3-T5B. * resolv/base64.c: Update from BIND 8.2.3-T5B. * resolv/herror.c: Likewise. * resolv/inet_addr.c: Likewise. * resolv/inet_net_ntop.c: Likewise. * resolv/inet_net_pton.c: Likewise. * resolv/inet_neta.c: Likewise. * resolv/inet_ntop.c: Likewise. * resolv/nsap_addr.c: Likewise. * resolv/inet_pton.c: Likewise. Reject a few more more invalid IPv6 addresses (ISC bug #520). * resolv/ns_name.c: Avoid emitting RCS ID in object file. * resolv/ns_parse.c: Likewise. * resolv/ns_netint.c: Likewise. * resolv/ns_samedomain.c: Likewise. * resolv/ns_ttl.c: Likewise. * resolv/ns_print.c: Update from BIND 8.2.3-T5B. Avoid emitting RCS ID in object file. * resolv/res_debug.c: Update from BIND 8.2.3-T5B. * resolv/res_mkquery.c: Likewise. * resolv/res_query.c: Likewise. * resolv/res_init.c: Likewise. (res_setoptions): Mark internal. * resolv/res_send.c: Likewise. [_LIBC]: Fully reinstate the code that avoids the FD_SETSIZE limit by using poll instead. * resolv/res_comp.c: Likewise. [SHLIB_COMPAT (libresolv, GLIBC_2_0, GLIBC_2_2)]: Make dn_expand a weak alias for __dn_expand. * resolv/res_data.c: Likewise. (res_close) [_LIBC]: Don't call res_nclose if RES_INIT isn't set in _res.options. Avoids a potential security risk by avoiding a close (0). [SHLIB_COMPAT (libresolv, GLIBC_2_0, GLIBC_2_2)]: Make res_mkquery, res_query, res_querydomain adn res_search weak aliases for __res_mkquery, __res_query, __res_querydomain and __res_search. * resolv/res_libc.c: (_res): Don't initialize. Fix res_close instead to avoid close(0). (res_init): Always use the static resolver context. [SHLIB_COMPAT (libc, GLIBC_2.0, GLIBC_2_2)]: Make res_init a weak alias for __res_init. * resolv/resolv.h: Update from BIND 8.2.3-T5B. Move definition of RES_SET_H_ERRNO and accompanying comment to... * include/resolv.h: ... here. * resolv/arpa/namser.h: Update from BIND 8.2.3-T5B. * resolv/arpa/nameser_compat.h: Likewise.
