Subject: [PATCH v2 19/37] kasan: don't allow SW_TAGS with ARM64_MTE
Date: Tue, 15 Sep 2020 23:16:01 +0200 [thread overview]
Message-ID: <42f25c11d97aa8497ee3851ee3531b379d6a922e.1600204505.git.andreyknvl@google.com> (raw)
In-Reply-To: <cover.1600204505.git.andreyknvl@google.com>
Software tag-based KASAN provides its own tag checking machinery that
can conflict with MTE. Don't allow enabling software tag-based KASAN
when MTE is enabled.
