From 2f54c82dacba646139a773ab43fc2cdb47ee1f5b Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Fri, 21 Jul 2000 04:12:25 +0000 Subject: 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 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 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 * sysdeps/mach/hurd/dl-sysdep.c: Likewise. --- hesiod/nss_hesiod/hesiod-grp.c | 79 ++++++++++-------------------------------- 1 file changed, 18 insertions(+), 61 deletions(-) (limited to 'hesiod/nss_hesiod/hesiod-grp.c') diff --git a/hesiod/nss_hesiod/hesiod-grp.c b/hesiod/nss_hesiod/hesiod-grp.c index a973fab80f..2d5b96b7f9 100644 --- a/hesiod/nss_hesiod/hesiod-grp.c +++ b/hesiod/nss_hesiod/hesiod-grp.c @@ -21,11 +21,12 @@ #include #include #include +#include #include #include #include -#include -#include + +#include "nss_hesiod.h" /* Get the declaration of the parser function. */ #define ENTNAME grent @@ -33,50 +34,15 @@ #define EXTERN_PARSER #include -/* Locks the static variables in this file. */ -__libc_lock_define_initialized (static, lock); - -static void *context = NULL; - -static enum nss_status -internal_setgrent (void) -{ - if (!context) - { - if (hesiod_init (&context) == -1) - return NSS_STATUS_UNAVAIL; - } - - return NSS_STATUS_SUCCESS; -} - enum nss_status _nss_hesiod_setgrent (void) { - enum nss_status status; - - __libc_lock_lock (lock); - - status = internal_setgrent (); - - __libc_lock_unlock (lock); - - return status; + return NSS_STATUS_SUCCESS; } enum nss_status _nss_hesiod_endgrent (void) { - __libc_lock_lock (lock); - - if (context) - { - hesiod_end (context); - context = NULL; - } - - __libc_lock_unlock (lock); - return NSS_STATUS_SUCCESS; } @@ -84,32 +50,37 @@ static enum nss_status lookup (const char *name, const char *type, struct group *grp, char *buffer, size_t buflen, int *errnop) { - enum nss_status status; struct parser_data *data = (void *) buffer; size_t linebuflen; + void *context; char **list; int parse_res; size_t len; - status = internal_setgrent (); - if (status != NSS_STATUS_SUCCESS) - return status; + context = _nss_hesiod_init (); + if (context == NULL) + return NSS_STATUS_UNAVAIL; list = hesiod_resolve (context, name, type); if (list == NULL) - return errno == ENOENT ?
