Subject: [PATCH v25 08/25] LSM: Use lsmblob in security_secid_to_secctx
Date: Tue,  9 Mar 2021 06:42:26 -0800
Message-ID: <20210309144243.12519-9-casey@schaufler-ca.com> (raw)
In-Reply-To: <20210309144243.12519-1-casey@schaufler-ca.com>

Change security_secid_to_secctx() to take a lsmblob as input
instead of a u32 secid. It will then call the LSM hooks
using the lsmblob element allocated for that module. The
callers have been updated as well. This allows for the
possibility that more than one module may be called upon
to translate a secid to a string, as can occur in the
audit code.
