Subject: Re: [RFC PATCH v2 08/11] KEYS: trusted: TEE: Synchronize session lifetime
Date: Wed, 04 Nov 2026 03:03:07 +0000 [thread overview]
Message-ID: <sashiko-outbox-196572@kernel.org> (raw)
In-Reply-To: <20261103030226.2685251-9-jarkko@kernel.org>
> Even with sysfs bind attributes suppressed on trusted_key_driver, the
> parent TEE device can still remove trusted_key_device while live trusted
> keys keep trusted.ko loaded, and init_trusted() updated static calls
> only after backend init() had already registered key_type_trusted.
>
> Update the static calls before invoking backend init() and reset them on
> failure. In the TEE backend, guard session context state with a mutex,
> publish pvt_data.dev before registering key_type_trusted, sanitize
> pvt_data on probe failure and remove, and reject seal/unseal/get_random
> with -ENODEV when no active TEE session is bound.
