__stack_chk_fail is called on corrupted stack. Stack backtrace is very unreliable against corrupted stack. __libc_message is changed to accept enum __libc_message_action and call BEFORE_ABORT only if action includes do_backtrace. __fortify_fail_abort is added to avoid backtrace from __stack_chk_fail. [BZ #12189] * debug/Makefile (CFLAGS-tst-ssp-1.c): New. (tests): Add tst-ssp-1 if -fstack-protector works. * debug/fortify_fail.c: Include <stdbool.h>. (_fortify_fail_abort): New function. (__fortify_fail): Call _fortify_fail_abort. (__fortify_fail_abort): Add a hidden definition. * debug/stack_chk_fail.c: Include <stdbool.h>. (__stack_chk_fail): Call __fortify_fail_abort, instead of __fortify_fail. * debug/tst-ssp-1.c: New file. * include/stdio.h (__libc_message_action): New enum. (__libc_message): Replace int with enum __libc_message_action. (__fortify_fail_abort): New hidden prototype. * malloc/malloc.c (malloc_printerr): Update __libc_message calls. * sysdeps/posix/libc_fatal.c (__libc_message): Replace int with enum __libc_message_action. Call BEFORE_ABORT only if action includes do_backtrace. (__libc_fatal): Update __libc_message call. |
