Subject: [PATCH 0/3] x86: Fixes to shadowing dom0
Date: Fri, 9 Nov 2018 15:26:15 +0000 [thread overview]
Message-ID: <1541777178-3844-1-git-send-email-andrew.cooper3@citrix.com> (raw)
It turns out there are some real bugs attempting to shadow dom0, and it is
because of these that XSA-273 went out with `pv-l1tf=` defaulting to not
shadowing dom0. They aren't security issues themselves.
Patch 1 is a general problem with dom0 and 1G superpages, and wants to be
taken onto all releases.
Patches 2 and 3 are various backports of work already upstream, to fix the
shadowing of PV guests with 2M superpages.
~Andrew
