Message-Id: <20220907225520.55855-1-keescook@chromium.org> Date: Wed, 7 Sep 2022 15:55:20 -0700 From: Kees Cook <keescook@...omium.org> To: Russell King <linux@...linux.org.uk> Cc: Kees Cook <keescook@...omium.org>, kernel test robot <lkp@...el.com>, linux-arm-kernel@...ts.infradead.org, Chris Down <chris@...isdown.name>, linux-kernel@...r.kernel.org, linux-hardening@...r.kernel.org Subject: [PATCH] ARM: decompressor: Include .data.rel.ro.local The .data.rel.ro.local section has the same semantics as .data.rel.ro here, so include it in the .rodata section of the decompressor. Additionally, Since the .printk_index section isn't usable outside of the core kernel, discard it in the decompressor. Avoids these warnings: arm-linux-gnueabi-ld: warning: orphan section `.data.rel.ro.local' from `arch/arm/boot/compressed/fdt_rw.o' being placed in section `.data.rel.ro.local' arm-linux-gnueabi-ld: warning: orphan section `.printk_index' from `arch/arm/boot/compressed/fdt_rw.o' being placed in section `.printk_index' Reported-by: kernel test robot <lkp@...el.com> Link: https://lore.kernel.org/linux-mm/202209080545.qMIVj7YM-lkp@intel.com Cc: Russell King <linux@...linux.org.uk> Cc: linux-arm-kernel@...ts.infradead.org Signed-off-by: Kees Cook <keescook@...omium.org> --- arch/arm/boot/compressed/vmlinux.lds.S | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/arm/boot/compressed/vmlinux.lds.S b/arch/arm/boot/compressed/vmlinux.lds.S index 1bcb68ac4b01..3fcb3e62dc56 100644 --- a/arch/arm/boot/compressed/vmlinux.lds.S +++ b/arch/arm/boot/compressed/vmlinux.lds.S @@ -23,6 +23,7 @@ SECTIONS *(.ARM.extab*) *(.note.*) *(.rel.*) + *(.printk_index) /* * Discard any r/w data - this produces a link error if we have any, * which is required for PIC decompression.
