Subject: [PATCH v3 0/4] basic KASAN support for Xen PV domains
Date: Fri, 7 Feb 2020 14:26:48 +0000 [thread overview]
Message-ID: <20200207142652.670-1-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
