Subject: [RFC PATCH v3 06/11] KEYS: trusted: TEE: Disable sysfs bind attributes
Date: Thu, 5 Nov 2026 02:53:05 +0200 [thread overview]
Message-ID: <20261105005311.804098-7-jarkko@kernel.org> (raw)
In-Reply-To: <20261105005311.804098-1-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>
