[PATCH v1 0/4] basic KASAN support for Xen PV domains
From: Sergey Dyasli
Date: Wed Jan 08 2020 - 10:28:25 EST
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 with KASAN
