Subject: [PATCH v39 32/42] LSM: Identify which LSM handles the context string
Date: Fri, 15 Dec 2023 14:16:26 -0800 [thread overview]
Message-ID: <20231215221636.105680-33-casey@schaufler-ca.com> (raw)
In-Reply-To: <20231215221636.105680-1-casey@schaufler-ca.com>
The security_secctx_to_secid() call can only interpret the
context string for a single LSM. Use the first LSM that supplies a hook.
