* nscd/nscd.c (termination_handler): Avoid segfault if some database is not enabled. * nscd/nscd_getai.c (__nscd_getai): If ai_resp->found == -1, set __nss_not_use_nscd_hosts and return -1. * nscd/nscd_initgroups.c (__nscd_getgrouplist): If initgr_resp->found == -1, set __nss_not_use_nscd_group and return -1. Avoid leaking sockets. 2005-01-28 Andreas Schwab <schwab@suse.de> H.J. Lu <hongjiu.lu@intel.com> [BZ #677] * elf/dl-runtime.c (fixup): Change return type to DL_FIXUP_VALUE_TYPE. Use DL_FIXUP_VALUE_TYPE, DL_FIXUP_MAKE_VALUE and DL_FIXUP_VALUE_CODE_ADDR for relocation values. Use DL_FIXUP_VALUE_ADDR and DL_FIXUP_ADDR_VALUE to store and retrieve relocation values. (profile_fixup): Likewise. * include/link.h (link_map): Use DL_FIXUP_VALUE_TYPE for l_reloc_result. * sysdeps/generic/dl-fptr.h (link_map): Forward declaration. * sysdeps/generic/dl-lookupcfg.h (DL_FIXUP_VALUE_TYPE): New. (DL_FIXUP_MAKE_VALUE): Likewise. (DL_FIXUP_VALUE_CODE_ADDR): Likewise. (DL_FIXUP_VALUE_ADDR): Likewise. (DL_FIXUP_ADDR_VALUE): Likewise. * sysdeps/ia64/dl-lookupcfg.h: Include <dl-fptr.h> for "struct fdesc". (DL_FIXUP_VALUE_TYPE): New. (DL_FIXUP_MAKE_VALUE): Likewise. (DL_FIXUP_VALUE_CODE_ADDR): Likewise. (DL_FIXUP_VALUE_ADDR): Likewise. (DL_FIXUP_ADDR_VALUE): Likewise. * sysdeps/ia64/dl-machine.h (elf_machine_profile_fixup_plt): Removed. (elf_machine_profile_plt): Removed. (elf_machine_fixup_plt): Change return type and type of value parameter to struct fdesc. (elf_machine_plt_value): Likewise. (elf_machine_rela): Use DL_FIXUP_MAKE_VALUE to construct argument for elf_machine_fixup_plt. 2005-02-07 Jakub Jelinek <jakub@redhat.com>
