Subject: [PATCH 0/2] net: socket: Fix potential spectre v1 gadgets
Date: Fri, 27 Jul 2018 22:43:00 +0000 [thread overview]
Message-ID: <20180727224302.5503-1-jcline@redhat.com> (raw)
Hi folks,
This fixes a pair of potential spectre v1 gadgets.
Note that because the speculation window is large, the policy is to stop
the speculative out-of-bounds load and not worry if the attack can be
completed with a dependent load or store[0].
