Subject: [PATCH v2 0/2] kasan: reset tag when accessing invalid data
Date: Wed, 4 Aug 2021 16:22:28 +0800	[thread overview]
Message-ID: <20210804082230.10837-1-Kuan-Ying.Lee@mediatek.com> (raw)

With hardware tag-based kasan enabled, we reset the tag
when we access metadata to avoid from false alarm.

Changes since v2:
 - Refine the commit message in detail.
 - Thanks Andrey's explanation about false alarm
   of kmemleak.

Kuan-Ying Lee (2):
  kasan, kmemleak: reset tags when scanning block
  kasan, slub: reset tag when printing address
