Subject: [RFC 0/2] SROP Mitigation for powerpc
Date: Tue, 17 May 2016 17:47:49 +1000 [thread overview]
Message-ID: <1463471271-26788-1-git-send-email-rashmicy@gmail.com> (raw)
This is all derived from Scott Bauer's x86 patches (https://lkml.org/lkml/2016/3/29/788). Have tested rc5 with these patches on:
- BE VM
- BE bare metal
- LE VM
- LE bare metal
with the Linux Test Project runltp test script with all default configs. From rc5 to rc5 with these patches no new tests failed.
Any comments/suggestions are welcome!
