From mboxrd@z Thu Jan 1 00:00:00 1970 From: Carlos Santos Date: Fri, 2 Feb 2018 13:56:12 -0200 Subject: [Buildroot] [PATCH 2/4] tpm2-abrmd: new package In-Reply-To: <20180202155614.26938-1-casantos@datacom.ind.br> References: <20180202155614.26938-1-casantos@datacom.ind.br> Message-ID: <20180202155614.26938-3-casantos@datacom.ind.br> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net This is a system daemon implementing the TPM2 access broker (TAB) & Resource Manager (RM) spec from the TCG. The daemon (tpm2-abrmd) is implemented using Glib and the GObject system. Communication between the daemon and clients using the TPM is done with a combination of DBus and Unix pipes. DBus is used for discovery, session management and the 'cancel', 'setLocality', and 'getPollHandles' API calls (mostly these aren't yet implemented). Pipes are used to send and receive TPM commands and responses (respectively) between client and server. The daemon owns the com.intel.tss2.Tabrmd name on dbus. It can be configured to connect to either the system or the session bus. The package also provides a client library for interacting with the daemon via TPM Command Transmission Interface (TCTI). It is intended for use with the SAPI library (libsapi) like any other TCTI.
