Subject: [PATCH 4.14 110/115] kvm: x86: Set highest physical address bits in non-present/reserved SPTEs
Date: Thu, 13 Sep 2018 15:32:10 +0200
Message-ID: <20180913131830.061070299@linuxfoundation.org> (raw)
In-Reply-To: <20180913131823.327472833@linuxfoundation.org>

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Junaid Shahid <junaids@google.com>

commit 28a1f3ac1d0c8558ee4453d9634dad891a6e922e upstream.

Always set the 5 upper-most supported physical address bits to 1 for SPTEs
that are marked as non-present or reserved, to make them unusable for
L1TF attacks from the guest. Currently, this just applies to MMIO SPTEs.
(We do not need to mark PTEs that are completely 0 as physical page 0
is already reserved.)

This allows mitigation of L1TF without disabling hyper-threading by using
shadow paging mode instead of EPT.
