Subject: [PATCH v5 5/5] powerpc/configs: Enable STRICT_MODULE_RWX in skiroot_defconfig
Date: Wed, 30 Oct 2019 18:31:11 +1100 [thread overview]
Message-ID: <20191030073111.140493-6-ruscur@russell.cc> (raw)
In-Reply-To: <20191030073111.140493-1-ruscur@russell.cc>
skiroot_defconfig is the only powerpc defconfig with STRICT_KERNEL_RWX
enabled, and if you want memory protection for kernel text you'd want it
for modules too, so enable STRICT_MODULE_RWX there.
