From mboxrd@z Thu Jan 1 00:00:00 1970 From: stefanb@linux.vnet.ibm.com (Stefan Berger) Date: Thu, 4 May 2017 10:56:26 -0400 Subject: [PATCH v3 2/3] tpm: vtpm_proxy: Implement request_locality function. In-Reply-To: <1493909787-1848-1-git-send-email-stefanb@linux.vnet.ibm.com> References: <1493909787-1848-1-git-send-email-stefanb@linux.vnet.ibm.com> Message-ID: <1493909787-1848-3-git-send-email-stefanb@linux.vnet.ibm.com> To: linux-security-module@vger.kernel.org List-Id: linux-security-module.vger.kernel.org Implement the request_locality function. Accept all localities assuming that the recipient (TPM emulator) handling TPM commands with prepended locality modifier will check for a valid locality and return a TPM error in case the locality is invalid.
