Subject: [PATCH 37/59] LSM: Create a data structure for a security context
Date: Tue, 9 Apr 2019 14:39:24 -0700 [thread overview]
Message-ID: <20190409213946.1667-38-casey@schaufler-ca.com> (raw)
In-Reply-To: <20190409213946.1667-1-casey@schaufler-ca.com>
A "security context" is the text representation of
the information used by LSMs. This provides a structure
so that the use can be made consistant.
