Subject: init_on_free breaks hibernate
Date: Mon, 23 Dec 2019 22:13:09 +0100 [thread overview]
Message-ID: <20191223211309.GA4609@sig21.net> (raw)
Hi,
I upgraded the kernel on one of my machines to 5.3.18 (from 5.2.x)
and found it failed after resume from hibernate due to what seemed
to be memory corruption. I had a hunch it could be related to
CONFIG_INIT_ON_ALLOC_DEFAULT_ON or CONFIG_INIT_ON_FREE_DEFAULT_ON,
and a quick web search found this which seems to confirm:
https://bbs.archlinux.org/viewtopic.php?pid=1877845#p1877845
I rebuilt the kernel with CONFIG_INIT_ON_FREE_DEFAULT_ON disabled,
and hibernate works again. I'm fine with this workaround and
just wanted to share this information.
The commit that introduces CONFIG_INIT_ON_FREE_DEFAULT_ON:
6471384af2a6 mm: security: introduce init_on_alloc=1 and init_on_free=1 boot options
FWIW, these errors made it into /var/log/kern.log after resume before
I had to press the reset button:
