Subject: [PATCH v2 0/4] basic KASAN support for Xen PV domains
Date: Fri, 17 Jan 2020 12:58:30 +0000	[thread overview]
Message-ID: <20200117125834.14552-1-sergey.dyasli@citrix.com> (raw)

This series allows to boot and run Xen PV kernels (Dom0 and DomU) with
CONFIG_KASAN=y. It has been used internally for some time now with good
results for finding memory corruption issues in Dom0 kernel.

Only Outline instrumentation is supported at the moment.

Sergey Dyasli (2):
  kasan: introduce set_pmd_early_shadow()
  x86/xen: add basic KASAN support for PV kernel

Ross Lagerwall (2):
  xen: teach KASAN about grant tables
  xen/netback: fix grant copy across page boundary
