* elf/Makefile (tests): Add nodlopen. Add rules to generate nodlopen. * include/dlfcn.h: Define __RTLD_DLOPEN. * elf/dl-load.c (_dl_map_object_from_fd): If DF_1_NOOPEN is set and this is a dlopen() call, do not load the binary. * dlfcn/dlopen.c: Add __RTLD_DLOPEN to mode passed down to _dl_open. * dlfcn/dlopenold.c: Likewise. * configure.in: Add test for -z nodelete option. * config.make.in: Define have-z-nodelete with libc_cv_z_nodelete. 2000-07-20 Mark Kettenis <kettenis@gnu.org> Make Hesiod NSS module thread-safe. * hesiod/README.hesiod: Update. * hesiod/Versions [GLIBC_2.2]: Add _nss_hesiod_getservbyport_r, _nss_hesiod_setprotoent, _nss_hesiod_endprotoent, _nss_hesiod_getprotobyname_r, and _nss_hesiod_getprotobynumber_r. * hesiod/Makefile (libnss_hesiod-routines): Add hesiod-init and hesiod-proto. * hesiod/nss_hesiod/hesiod-init.c: New file. * hesiod/nss_hesiod/hesiod-pwd.c: Rewritten for thread-safeness. * hesiod/nss_hesiod/hesiod-grp.c: Likewise. * hesiod/nss_hesiod/nss_hesiod.h: New file. * hesiod/nss_hesiod/hesiod-service.c (_nss_hesiod_getservbyport_r): New function. Provide support for looking up services by port number. * hesiod/nss_hesiod/hesiod-proto.c: New file. * hesiod/hesiod.c: Update from BIND 8.2.3-T5B. * hesiod/hesiod.h: Likewise. * hesiod/hesiod_p.h: Likewise. 2000-07-20 Mark Kettenis <kettenis@gnu.org> Fix problems with `struct __res_state' getting too big. * resolv/resolv.h (struct __sockaddr_in): New definition. (struct __res_state): Use __sockaddr_in instead of sockaddr_in in the private parts of the structure to save some space. * resolv/res_send.c (res_nsend): Cast &EXT(statp).nsaddrs[ns] to (struct sockaddr_in *) in call to sock_eq. Use memcpy to copy statp->nsaddr_list[ns] to &EXT(statp).nsaddrs[ns]. 2000-07-20 Ulrich Drepper <drepper@redhat.com> * sysdeps/mach/hurd/dl-sysdep.c: Likewise.
