Subject: [PATCH AUTOSEL 6.0 14/18] ARM: decompressor: Include .data.rel.ro.local
Date: Sun, 9 Oct 2022 16:51:31 -0400 [thread overview]
Message-ID: <20221009205136.1201774-14-sashal@kernel.org> (raw)
In-Reply-To: <20221009205136.1201774-1-sashal@kernel.org>
From: Kees Cook <keescook@chromium.org>
[ Upstream commit 1b64daf413acd86c2c13f5443f6b4ef3690c8061 ]
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'
