From mboxrd@z Thu Jan 1 00:00:00 1970 From: Kees Cook Subject: [PATCH 0/2] gcc-plugins: structleak: Generalize to all variable types Date: Tue, 12 Feb 2019 10:04:39 -0800 Message-Id: <20190212180441.15340-1-keescook@chromium.org> To: linux-kernel@vger.kernel.org Cc: Kees Cook , Emese Revfy , Alexander Popov , Ard Biesheuvel , Laura Abbott , Jann Horn , Alexander Potapenko , kernel-hardening@lists.openwall.com List-ID: Instead of a new plugin for stack initialization[1], this improves structleak to handle initialization of all variable types. Since the instrumentation happens at a different point, the "switch" statement changes from the earlier posting[2] are no longer needed. As before, this also introduces a stack initialization regression testing module to validate various kinds of stack variable usage vs compiler instrumentation for initialization. See the individual patches for more details.
