Subject: [PATCH v5 37/38] LSM: Infrastructure management of the ipc security blob
Date: Mon, 26 Nov 2018 15:56:02 -0800
Message-ID: <fcf07080-4e73-9f54-2e22-de48782806ed@schaufler-ca.com> (raw)
In-Reply-To: <50db058a-7dde-441b-a7f9-f6837fe8b69f@schaufler-ca.com>

Move management of the kern_ipc_perm->security and
msg_msg->security blobs out of the individual security
modules and into the security infrastructure. Instead
of allocating the blobs from within the modules the modules
tell the infrastructure how much space is required, and
the space is allocated there.
