[PATCH 0/2] fs/quota: Fix potential spectre v1 gadgets

From: Jeremy Cline
Date: Mon Jul 30 2018 - 21:37:49 EST


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.

Jeremy Cline (2):
fs/quota: Replace XQM_MAXQUOTAS usage with MAXQUOTAS
fs/quota: Fix spectre gadget in do_quotactl
