Subject: [PATCH v2 5/5] ima: modify arguments of tpm_pcr_extend()
Date: Fri, 5 May 2017 16:21:52 +0200 [thread overview]
Message-ID: <20170505142152.29795-6-roberto.sassu@huawei.com> (raw)
In-Reply-To: <20170505142152.29795-1-roberto.sassu@huawei.com>
ima_pcr_extend() has been modified to pass the correct arguments
to tpm_pcr_extend(): the pointer of a tpm2_digest structure containing
the template digest and the size of the array (1).
