Subject: [PATCH 0/5 v16] KASan for Arm
Date: Mon, 19 Oct 2020 10:41:35 +0200	[thread overview]
Message-ID: <20201019084140.4532-1-linus.walleij@linaro.org> (raw)

This is the 16th and final (knock on wood) version of
KASan for ARM32.

Changes since v15:

- Things now work on all boards we have tested on including
  Broadcom and i.MX6Q.

- Folded in a fix from Ard to PAGE_ALIGN() the end of
  mappings making everything work on all Broadcom board.

- Folded in a fix from Ahmad Fatoum making things work
  with fortify on i.MX6Q.

- Testing and testing and testing on build servers.

- We are good to go.

I will now put this in Russell's patch tracker for v5.11.

There is a git branch you can pull in:
https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator.git/log/?h=kasan

This branch includes Ard's two patches already in Russell's
patch tracker.


Abbott Liu (1):
  ARM: Define the virtual space of KASan's shadow region

Andrey Ryabinin (3):
  ARM: Disable KASan instrumentation for some code
  ARM: Replace string mem* functions for KASan
  ARM: Enable KASan for ARM

Linus Walleij (1):
  ARM: Initialize the mapping of KASan shadow memory
