Subject: [PATCH v7 21/28] NET: Store LSM netlabel data in a lsmblob
Date: Wed,  7 Aug 2019 12:44:03 -0700
Message-ID: <20190807194410.9762-22-casey@schaufler-ca.com> (raw)
In-Reply-To: <20190807194410.9762-1-casey@schaufler-ca.com>

Netlabel uses LSM interfaces requiring an lsmblob and
the internal storage is used to pass information between
these interfaces, so change the internal data from a secid
to a lsmblob. Update the netlabel interfaces and their
callers to accommodate the change. This requires that the
modules using netlabel use the lsm_id.slot to access the
correct secid when using netlabel.
