* csu/elf-init.c (__libc_csu_fini): Don't do anything here.
* sysdeps/generic/libc-start.c: Don't register program destructor here. * dlfcn/Makefile: Add rules to build dlfcn.c. (LDFLAGS-dl.so): Removed. * dlfcn/dlclose.c: _dl_close is now in ld.so, use function pointer table. * dlfcn/dlmopen.c: Likewise for _dl_open. * dlfcn/dlopen.c: Likewise. * dlfcn/dlopenold.c: Likewise. * elf/dl-libc.c: Likewise for _dl_open and _dl_close. * elf/Makefile (routines): Remove dl-open and dl-close. (dl-routines): Add dl-open, dl-close, and dl-trampoline. Add rules to build and run tst-audit1. * elf/tst-audit1.c: New file. * elf/tst-auditmod1.c: New file. * elf/Versions [libc]: Remove _dl_open and _dl_close. * elf/dl-close.c: Change for use inside ld.so instead of libc.so. * elf/dl-open.c: Likewise. * elf/dl-debug.c (_dl_debug_initialize): Allow reinitialization, signaled by nonzero parameter. * elf/dl-init.c: Fix use of r_state. * elf/dl-load.c: Likewise. * elf/dl-close.c: Add auditing checkpoints. * elf/dl-open.c: Likewise. * elf/dl-fini.c: Likewise. * elf/dl-load.c: Likewise. * elf/dl-sym.c: Likewise. * sysdeps/generic/libc-start.c: Likewise. * elf/dl-object.c: Allocate memory for auditing information. * elf/dl-reloc.c: Remove RESOLV.

Correctly initialize slotinfo. * elf/dynamic-link.h: Adjust after removal of RESOLV. * sysdeps/hppa/dl-lookupcfg.h: Likewise. * sysdeps/ia64/dl-lookupcfg.h: Likewise. * sysdeps/powerpc/powerpc64/dl-lookupcfg.h: Removed. * elf/dl-runtime.c (_dl_fixup): Little cleanup. (_dl_profile_fixup): New parameters to point to register struct and variable for frame size. Add auditing checkpoints. (_dl_call_pltexit): New function. Don't define trampoline code here. * elf/rtld.c: Recognize LD_AUDIT. Load modules on startup. Remove all the functions from _rtld_global_ro which only _dl_open and _dl_close needed. Add auditing checkpoints. * elf/link.h: Define symbols for auditing interfaces. * include/link.h: Likewise. * include/dlfcn.h: Define __RTLD_AUDIT. Remove prototypes for _dl_open and _dl_close. Adjust access to argc and argv in libdl. * dlfcn/dlfcn.c: New file. * sysdeps/generic/dl-lookupcfg.h: Remove all content now that RESOLVE is gone. * sysdeps/generic/ldsodefs.h: Add definitions for auditing interfaces. * sysdeps/generic/unsecvars.h: Add LD_AUDIT. * sysdeps/i386/dl-machine.h: Remove trampoline code here.
