[Xen-devel] [RFC PATCH 0/3] basic KASAN support for Xen PV domains

[Sergey Dyasli <sergey.dyasli@xxxxxxxxxx>]

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
