From: Hauke Mehrtens Date: Sat, 22 Apr 2023 17:52:22 +0000 (+0200) Subject: kernel: Activate CONFIG_ARM64_SW_TTBR0_PAN X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=ca5555d27e6c62229a3f17d7ac2158d3c24b6af9;p=openwrt%2Fstaging%2Fjow.git kernel: Activate CONFIG_ARM64_SW_TTBR0_PAN This activates the CONFIG_ARM64_SW_TTBR0_PAN option for all arm64 kernels by default. The CONFIG_ARM64_SW_TTBR0_PAN option prevents the kernel form accessing user space memory directly. This makes it harder to exploit the kernel. This is activated by default and was already activate on all other arm64 targets before.
