* sysdeps/generic/dl-osinfo.h (_dl_setup_stack_chk_guard): Take
one parameter. If non-NULL use it to initialize return value. (_dl_setup_pointer_guard): New function. * sysdeps/unix/sysv/linux/dl-osinfo.h: Likewise. * sysdeps/generic/ldsodefs.h: Declare _dl_random. * elf/rtld.c (security_init): Pass _dl_random to _dl_setup_stack_chk_guard. Call _dl_setup_pointer_guard to initialize pointer_chk_guard. * elf/dl-sysdep.c (_dl_random): New variable. (_dl_sysdep_start): Handle AT_RANDOM. (_dl_show_auxv): Likewise. * elf/dl-support.c (_dl_random): New variable. (_dl_aux_init): Handle AT_RANDOM. * csu/libc-start.c [!SHARED] (libc_start_main): Pass _dl_random to _dl_setup_stack_chk_guard. * elf/elf.h (AT_RANDOM): Define AT_BASE_PLATFORM and AT_RANDOM.
