Subject: [PATCH v38 36/39] netlabel: Use a struct lsmblob in audit data
Date: Tue, 27 Sep 2022 12:54:18 -0700 [thread overview]
Message-ID: <20220927195421.14713-37-casey@schaufler-ca.com> (raw)
In-Reply-To: <20220927195421.14713-1-casey@schaufler-ca.com>
Remove scaffolding in netlabel audit by keeping subject
lsm information in an lsmblob structure instead of a secid.
Acked-by: Paul Moore <paul@paul-moore.com>
