From: Ard Biesheuvel Date: Tue, 22 Jan 2019 11:09:12 +0000 (+0100) Subject: ARM: multi_v7_defconfig: enable GCC plugin support and structleak plugin X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=34332ef736c09f87af87586a4080e94740c350e2;p=linux.git ARM: multi_v7_defconfig: enable GCC plugin support and structleak plugin Enable the base GCC plugin support symbol CONFIG_GCC_PLUGINS for multi_v7_defconfig so that builds hosted on systems that have a supported version of GCC along with the prerequisite headers will allow GCC plugins to be used during the build. At the moment, this will also enable the ARM per-task stack protector plugin, since all its remaining Kconfig dependencies are fulfilled by default. At the same time, enable the structleak plugin. This plugin ensures that local struct type variables are fully initialized, preventing inadvertent leaks of kernel state if such variables are shared with userland. This is a reasonable transformation to apply by default, since it does not adversely affect performance, and does not affect GCC compiler diagnostics regarding the use of uninitialized local variables.
