Subject: [PATCHv2 0/2] Hardening configs refactor/rename
Date: Fri,  3 Feb 2017 09:52:20 -0800	[thread overview]
Message-ID: <1486144343-24998-1-git-send-email-labbott@redhat.com> (raw)

Hi,

This is a follow up to my proposal to rename/refactor CONFIG_DEBUG_RODATA
and CONFIG_DEBUG_SET_MODULE_RONX. Among other objections, there shouldn't
be 'debug' in the name since these provide necessary kernel protection.

v2 takes a slightly different approach to this per feedback. Patch #1 moves
CONFIG_DEBUG_RODATA and CONFIG_DEBUG_SET_MODULE_RONX to a common arch config.
These configs are def_bool y for every arch except !CPU_V7 for arm
CONFIG_DEBUG_RODATA. I think this also mitigates another concern about changing
the name since these are basically internal configs at this point and not end
user selectable. Patch #2 does the rename to something more descriptive.
Hopefully this should separate discussion more clearly into two parts (refactor
and rename)

Thanks,
Laura
