Ulrich Drepper 6aa10807fc [BZ #677]
* 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.

	[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.
