Update.
* 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].

* sysdeps/mach/hurd/dl-sysdep.c: Likewise.
