Subject: [RFC PATCH v2 07/11] KEYS: trusted: TEE: Disable sysfs bind attributes
Date: Tue, 3 Nov 2026 05:02:12 +0200 [thread overview]
Message-ID: <20261103030226.2685251-8-jarkko@kernel.org> (raw)
In-Reply-To: <20261103030226.2685251-1-jarkko@kernel.org>
Suppress sysfs bind and unbind attributes on trusted_key_driver so that
userspace cannot unbind the driver and unregister key_type_trusted while
the trusted module remains loaded.
Signed-off-by: Jarkko Sakkinen <jarkko@kernel.org>
