Subject: unable to load modules with CONFIG_MODVERSIONS=y after commit 8ab2ae655b
Date: Tue, 6 Dec 2016 08:31:01 -0500 (EST) [thread overview]
Message-ID: <656276734.2322009.1481031061742.JavaMail.zimbra@redhat.com> (raw)

Hi,
Starting with 4.9-rc8 / commit 8ab2ae655b ("default exported asm symbols to zero")
I'm running into issue with kernel built with CONFIG_MODVERSIONS=y
and (older) binutils (binutils-2.25.1-20.base.el7.ppc64le).
Modules fail to load, for example:
[ 3.163646] Found checksum 0 vs module 4829A47E
[ 3.163787] dm_mod: disagrees about version of symbol memcpy
[ 3.163862] dm_mod: Unknown symbol memcpy (err -22)
Bisect led me to 8ab2ae655b, reverting it allows boot to
progress as before.
Regards,
Jan
