Subject: [Buildroot] [PATCH 2/4] tpm2-abrmd: new package
Date: Fri,  2 Feb 2018 13:56:12 -0200	[thread overview]
Message-ID: <20180202155614.26938-3-casantos@datacom.ind.br> (raw)
In-Reply-To: <20180202155614.26938-1-casantos@datacom.ind.br>

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.
