Subject: L1TF Patch Series v10
Date: Thu, 14 Mar 2019 13:50:03 +0100	[thread overview]
Message-ID: <1552567811-5301-1-git-send-email-nmanthey@amazon.de> (raw)

Dear all,

This patch series attempts to mitigate the issue that have been raised in the
XSA-289 (https://xenbits.xen.org/xsa/advisory-289.html). To block speculative
execution on Intel hardware, an lfence instruction is required to make sure
that selected checks are not bypassed. Speculative out-of-bound accesses can
be prevented by using the array_index_nospec macro.

The major change compared to version 9 is patch 8/8, which slipped through the
analysis in the first rounds.

Best,
Norbert
