From 626b37d70aad163089598e33da2590f838f6dd8c Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sat, 22 Apr 2023 15:52:56 +0200 Subject: kernel: Activate CONFIG_HARDENED_USERCOPY for all targets This activates CONFIG_HARDENED_USERCOPY for the remaining targets. This adds additional checks in the copy_from_user() and copy_to_user() functions. This was not activated for ARCHS38 before because of a bug in the Linux kernel 5.4 till 5.14, which as fixed and is described here: https://github.com/foss-for-synopsys-dwc-arc-processors/linux/issues/15 I do not know why this was deactivated for mt7629 and rockchip.
