Subject: [PATCH 3/3] WIP: arch/powerpc/boot: Add '-z norelro'
|
|
|
|
ld.bfd defaults to '-z norelro', whereas ld.lld defaults to '-z relro',
|
|
which results in an error when building cuImages:
|
|
|
|
ld.lld: error: section: .dynamic is not contiguous with other relro sections
|
|
|
|
Commit a538d184e3f0 ("powerpc/boot: Move the .got section to after the
|
|
.dynamic section") previously worked around this in the boot wrapper by
|
|
shuffling the sections but other areas of the kernel have just disabled
|
|
the relro program header altogether (see commit 3b92fa7485eb ("arm64:
|
|
link with -z norelro regardless of CONFIG_RELOCATABLE") and
|
|
commit 0cda9bc15dfc ("ARM: 9038/1: Link with '-z norelro'")).
