Subject: [PATCH v1 0/7] add more tests to MTE kselftests
Date: Tue, 25 Jan 2022 15:09:13 +0000	[thread overview]
Message-ID: <20220125150920.23955-1-joey.gouly@arm.com> (raw)

This is a series which refactors and then adds some extra tests for MTE
in the kselftest framework.

The issue that these tests are for was was fixed by Robin in
295cf156231c ("arm64: Avoid premature usercopy failure") and based on a
simplified example by Catalin [1].

They test some combinations of pointer offsets, sizes and syscalls to
exercise different paths in the kernel.

Thanks,
Joey
