[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. 2006-10-17 Jakub Jelinek <jakub@redhat.com> [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
