Subject: [PATCH v11 14/14] selftests, arm64: add a selftest for passing tagged pointers to kernel
Date: Fri, 15 Mar 2019 20:51:38 +0100 [thread overview]
Message-ID: <8e7bfcb3812ae2a1f558864f56eec71a8f78fa2e.1552679409.git.andreyknvl@google.com> (raw)
In-Reply-To: <cover.1552679409.git.andreyknvl@google.com>
This patch is a part of a series that extends arm64 kernel ABI to allow to
pass tagged user pointers (with the top byte set to something else other
than 0x00) as syscall arguments.
This patch adds a simple test, that calls the uname syscall with a
tagged user pointer as an argument. Without the kernel accepting tagged
user pointers the test fails with EFAULT.
