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.
Patch 1 is of RFC quality
Patches 2-3 are independent and quite self-contained.
Sergey Dyasli (1):
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
