Subject: [PATCH 7/8] sandbox: tpm: Fix TPM2_CC_NV_DEFINE_SPACE command
Date: Tue, 12 Sep 2023 02:47:30 -0700 [thread overview]
Message-ID: <20230912094731.51413-8-seanedmond@linux.microsoft.com> (raw)
In-Reply-To: <20230912094731.51413-1-seanedmond@linux.microsoft.com>
From: Sean Edmond <seanedmond@microsoft.com>
The TPM 2.0 command reference shows "auth" (type TPM2B_AUTH) before
"publicInfo" (type TPM2B_NV_PUBLIC).
The TPM v2 driver was updated to add this field. The sandbox driver
needs to be updated to match the driver implementation.
