Subject: [PATCH v9 6/8] powerpc/configs: Enable STRICT_MODULE_RWX in skiroot_defconfig
Date: Tue, 16 Mar 2021 14:17:39 +1100	[thread overview]
Message-ID: <20210316031741.1004850-6-jniethe5@gmail.com> (raw)
In-Reply-To: <20210316031741.1004850-1-jniethe5@gmail.com>

From: Russell Currey <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.
