Subject: [PATCH 0/2] fs/quota: Fix potential spectre v1 gadgets
Date: Tue, 31 Jul 2018 01:37:29 +0000 [thread overview]
Message-ID: <20180731013731.1987-1-jcline@redhat.com> (raw)
Hi folks,
This series unifies XQM_MAXQUOTAS with MAXQUOTAS, which were both being
used to perform bounds checks on arrays, and then sanitizes 'type' so it
can't be used in speculative out-of-bounds array access.
