BZ #15754: CVE-2013-4788 The pointer guard used for pointer mangling was not initialized for static applications resulting in the security feature being disabled. The pointer guard is now correctly initialized to a random value for static applications. Existing static applications need to be recompiled to take advantage of the fix. The test tst-ptrguard1-static and tst-ptrguard1 add regression coverage to ensure the pointer guards are sufficiently random and initialized to a default value. 2013-09-23 00:52:09 -04:00
BZ #15754: Fix test case for ARM. Statically built binaries use __pointer_chk_guard_local, while dynamically built binaries use __pointer_chk_guard. Provide the right definition depending on the test case we are building. 2013-09-23 01:44:38 -04:00			`#ifdef PTRGUARD_LOCAL`
