Subject: [PATCH 0/4] Fix ro_after_init vs static_call
Date: Wed,  1 Sep 2021 16:37:53 -0700	[thread overview]
Message-ID: <20210901233757.2571878-1-keescook@chromium.org> (raw)

Hi,

It seems the .static_call_sites section was not being marked as
ro-after-init in modules. Adjust the macro names, add comments, refactor
the module section list, and fix .static_call_sites.

Thanks!

-Kees

Kees Cook (4):
  vmlinux.lds.h: Use regular *RODATA and *RO_AFTER_INIT_DATA suffixes
  vmlinux.lds.h: Split .static_call_sites from .static_call_tramp_key
  module: Use a list of strings for ro_after_init sections
  module: Include .static_call_sites in module ro_after_init
