[BZ #3313]
2006-10-17 Jakub Jelinek <jakub@redhat.com>
* sunrpc/xdr_mem.c (xdrmem_setpos): Don't compare addresses
as signed longs, check for x_base + pos overflow.
* sunrpc/Makefile (tests): Add tst-xdrmem2.
* sunrpc/tst-xdrmem2.c: New test.
2006-10-18 Ulrich Drepper <drepper@redhat.com>
* elf/dl-lookup.c (_dl_lookup_symbol_x): Add warning to
_dl_lookup_symbol_x code.
2006-10-17 Jakub Jelinek <jakub@redhat.com>
* elf/dl-runtime.c: Include sysdep-cancel.h.
(_dl_fixup, _dl_profile_fixup): Use __rtld_mrlock_* and
scoperec->nusers only if !SINGLE_THREAD_P. Use atomic_*
instead of catomic_* macros.
* elf/dl-sym.c: Include sysdep-cancel.h.
(do_sym): Use __rtld_mrlock_* and scoperec->nusers only
if !SINGLE_THREAD_P. Use atomic_* instead of catomic_* macros.
* elf/dl-close.c: Include sysdep-cancel.h.
(_dl_close): Use __rtld_mrlock_* and scoperec->nusers only
if !SINGLE_THREAD_P. Use atomic_* instead of catomic_* macros.
* elf/dl-open.c: Include sysdep-cancel.h.
(dl_open_worker): Use __rtld_mrlock_* and scoperec->nusers only
if !SINGLE_THREAD_P. Use atomic_* instead of catomic_* macros.

[BZ #3313]
* malloc/malloc.c (malloc_consolidate): Set maxfb to address of last
fastbin rather than end of fastbin array.
2006-10-18 Ulrich Drepper <drepper@redhat.com>
* sysdeps/i386/i486/bits/atomic.h (catomic_decrement): Use correct
body macro.
* sysdeps/x86_64/bits/atomic.h
(__arch_c_compare_and_exchange_val_64_acq): Add missing casts.
(catomic_decrement): Use correct body macro.
2006-10-17 Jakub Jelinek <jakub@redhat.com>
* include/atomic.h: Add a unique prefix to all local variables
in macros.
* csu/tst-atomic.c (do_test): Test also catomic_* macros.
* include/link.h: Include <rtld-lowlevel.h>. Define struct
