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/li...
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
