It is assumed -that the user is fairly familiar with compiling and installing XEN -and Linux on a machine. +Copyright (c) 2010-2012 United States Government, as represented by +the Secretary of Defense. All rights reserved. +November 12 2012 +Authors: Matthew Fioravante (JHUAPL), + +This document describes the virtual Trusted Platform Module (vTPM) subsystem +for Xen. The reader is assumed to have familiarity with building and installing +Xen, Linux, and a basic understanding of the TPM and vTPM concepts. + +------------------------------ +INTRODUCTION +------------------------------ +The goal of this work is to provide a TPM functionality to a virtual guest +operating system (a DomU). This allows programs to interact with a TPM in a +virtual system the same way they interact with a TPM on the physical system. +Each guest gets its own unique, emulated, software TPM. However, each of the +vTPM''s secrets (Keys, NVRAM, etc) are managed by a vTPM Manager domain, which +seals the secrets to the Physical TPM. Thus, the vTPM subsystem extends the +chain of trust rooted in the hardware TPM to virtual machines in Xen. Each +major component of vTPM is implemented as a separate domain, providing secure +separation guaranteed by the hypervisor. The vTPM domains are implemented in +mini-os to reduce memory and processor overhead. + +This mini-os vTPM subsystem was built on top of the previous vTPM +work done by IBM and Intel corporation. -Production Prerequisites: An x86-based machine machine with a -Linux-supported TPM on the motherboard (NSC, Atmel, Infineon, TPM V1.2). -Development Prerequisites: An emulator for TESTING ONLY is provided - +------------------------------ +DESIGN OVERVIEW +------------------------------ + +The architecture of vTPM is described below: + ++------------------+ +| Linux DomU | ... +| | ^ | +| v | | +| xen-tpmfront | ++------------------+ + | ^ + v | ++------------------+ +| mini-os/tpmback | +| | ^ | +| v | | +| vtpm-stubdom | ... +| | ^ | +| v | | +| mini-os/tpmfront | ++------------------+ + | ^ + v | ++------------------+ +| mini-os/tpmback | +| | ^ | +| v | | +| vtpmmgrdom | +| | ^ | +| v | | +| mini-os/tpm_tis | ++------------------+ + | ^ + v | ++------------------+ +| Hardware TPM | ++------------------+ + * Linux DomU: The Linux based guest that wants to use a vTPM. There many be + more than one of these. + + * xen-tpmfront.ko: Linux kernel virtual TPM frontend driver. This driver + provides vTPM access to a para-virtualized Linux based DomU. + + * mini-os/tpmback: Mini-os TPM backend driver. The Linux frontend driver + connects to this backend driver to facilitate + communications between the Linux DomU and its vTPM. This + driver is also used by vtpmmgrdom to communicate with + vtpm-stubdom. + + * vtpm-stubdom: A mini-os stub domain that implements a vTPM. There is a + one to one mapping between running vtpm-stubdom instances and + logical vtpms on the system. The vTPM Platform Configuration + Registers (PCRs) are all initialized to zero. + + * mini-os/tpmfront: Mini-os TPM frontend driver. The vTPM mini-os domain + vtpm-stubdom uses this driver to communicate with + vtpmmgrdom. This driver could also be used separately to + implement a mini-os domain that wishes to use a vTPM of + its own. + + * vtpmmgrdom: A mini-os domain that implements the vTPM manager. + There is only one vTPM manager and it should be running during + the entire lifetime of the machine. This domain regulates + access to the physical TPM on the system and secures the + persistent state of each vTPM. + + * mini-os/tpm_tis: Mini-os TPM version 1.2 TPM Interface Specification (TIS) + driver. This driver used by vtpmmgrdom to talk directly to + the hardware TPM. Communication is facilitated by mapping + hardware memory pages into vtpmmgrdom. + + * Hardware TPM: The physical TPM that is soldered onto the motherboard. + +------------------------------ +INSTALLATION +------------------------------ + +Prerequisites: +-------------- +You must have an x86 machine with a TPM on the motherboard. +The only software requirement to compiling vTPM is cmake. +You must use libxl to manage domains with vTPMs. ''xm'' is +deprecated and does not support vTPM. Compiling the XEN tree: ----------------------- -Compile the XEN tree as usual after the following lines set in the -linux-2.6.??-xen/.config file: +Compile and install the XEN tree as usual. Be sure to build and install +the stubdom tree. + +Compiling the LINUX dom0 kernel: +-------------------------------- -CONFIG_XEN_TPMDEV_BACKEND=m +The Linux dom0 kernel has no special prerequisites. -CONFIG_TCG_TPM=m -CONFIG_TCG_TIS=m (supported after 2.6.17-rc4) -CONFIG_TCG_NSC=m -CONFIG_TCG_ATMEL=m -CONFIG_TCG_INFINEON=m -CONFIG_TCG_XEN=m -<possible other TPM drivers supported by Linux> +Compiling the LINUX domU kernel: +-------------------------------- -If the frontend driver needs to be compiled into the user domain -kernel, then the following two lines should be changed. +The domU kernel used by domains with vtpms must +include the xen-tpmfront.ko driver. It can be built +directly into the kernel or as a module. CONFIG_TCG_TPM=y CONFIG_TCG_XEN=y +------------------------------ +VTPM MANAGER SETUP +------------------------------ + +Manager disk image setup: +------------------------- + +The vTPM Manager requires a disk image to store its +encrypted data. The image does not require a filesystem +and can live anywhere on the host disk. The image does not need +to be large. 8 to 16 Mb should be sufficient. + +# dd if=/dev/zero of=/var/vtpmmgrdom.img bs=16M count=1 + +Manager config file: +-------------------- + +The vTPM Manager domain (vtpmmgrdom) must be started like +any other Xen virtual machine and requires a config file. +The manager requires a disk image for storage and permission +to access the hardware memory pages for the TPM. An +example configuration looks like the following. + +kernel="/usr/lib/xen/boot/vtpmmgrdom.gz" +memory=16 +disk=["file:/var/vtpmmgrdom.img,hda,w"] +name="vtpmmgrdom" +iomem=["fed40,5"] + +The iomem line tells xl to allow access to the TPM +IO memory pages, which are 5 pages that start at +0xfed40000. + +Starting and stopping the manager: +---------------------------------- + +The vTPM manager should be started at boot, you may wish to +create an init script to do this. + +# xl create -c vtpmmgrdom.cfg + +Once initialization is complete you should see the following: +INFO[VTPM]: Waiting for commands from vTPM''s: + +To shutdown the manager you must destroy it. To avoid data corruption, +only destroy the manager when you see the above "Waiting for commands" +message. This ensures the disk is in a consistent state. + +# xl destroy vtpmmgrdom + +------------------------------ +VTPM AND LINUX PVM SETUP +------------------------------ -You must also enable the virtual TPM to be built: +In the following examples we will assume we have Linux +guest named "domu" with its associated configuration +located at /home/user/domu. It''s vtpm will be named +domu-vtpm. -In Config.mk in the Xen root directory set the line +vTPM disk image setup: +---------------------- -VTPM_TOOLS ?= y +The vTPM requires a disk image to store its persistent +data. The image does not require a filesystem. The image +does not need to be large. 8 Mb should be sufficient. -and in +# dd if=/dev/zero of=/home/user/domu/vtpm.img bs=8M count=1 -tools/vtpm/Rules.mk set the line +vTPM config file: +----------------- -BUILD_EMULATOR = y +The vTPM domain requires a configuration file like +any other domain. The vTPM requires a disk image for +storage and a TPM frontend driver to communicate +with the manager. An example configuration is given: -Now build the Xen sources from Xen''s root directory: +kernel="/usr/lib/xen/boot/vtpm-stubdom.gz" +memory=8 +disk=["file:/home/user/domu/vtpm.img,hda,w"] +name="domu-vtpm" +vtpm=["backend=vtpmmgrdom,uuid=ac0a5b9e-cbe2-4c07-b43b-1d69e46fb839"] -make install +The vtpm= line sets up the tpm frontend driver. The backend must set +to vtpmmgrdom. You are required to generate a uuid for this vtpm. +You can use the uuidgen unix program or some other method to create a +uuid. The uuid uniquely identifies this vtpm to manager. +If you wish to clear the vTPM data you can either recreate the +disk image or change the uuid. -Also build the initial RAM disk if necessary. +Linux Guest config file: +------------------------ -Reboot the machine with the created Xen kernel. +The Linux guest config file needs to be modified to include +the Linux tpmfront driver. Add the following line: -Note: If you do not want any TPM-related code compiled into your -kernel or built as module then comment all the above lines like -this example: -# CONFIG_TCG_TPM is not set +vtpm=["backend=domu-vtpm"] +Currently only paravirtualized guests are supported. -Modifying VM Configuration files: ---------------------------------- +Launching and shut down: +------------------------ -VM configuration files need to be adapted to make a TPM instance -available to a user domain. The following VM configuration file is -an example of how a user domain can be configured to have a TPM -available. It works similar to making a network interface -available to a domain. +To launch a Linux guest with a vTPM we first have to start the vTPM domain. -kernel = "/boot/vmlinuz-2.6.x" -ramdisk = "/xen/initrd_domU/U1_ramdisk.img" -memory = 32 -name = "TPMUserDomain0" -vtpm = [''instance=1,backend=0''] -root = "/dev/ram0 console=tty ro" -vif = [''backend=0''] +# xl create -c /home/user/domu/vtpm.cfg -In the above configuration file the line ''vtpm = ...'' provides -information about the domain where the virtual TPM is running and -where the TPM backend has been compiled into - this has to be -domain 0 at the moment - and which TPM instance the user domain -is supposed to talk to. Note that each running VM must use a -different instance and that using instance 0 is NOT allowed. The -instance parameter is taken as the desired instance number, but -the actual instance number that is assigned to the virtual machine -can be different. This is the case if for example that particular -instance is already used by another virtual machine. The association -of which TPM instance number is used by which virtual machine is -kept in the file /var/vtpm/vtpm.db. Associations are maintained by -a xend-internal vTPM UUID and vTPM instance number. +After initialization is complete, you should see the following: +Info: Waiting for frontend domain to connect.. -Note: If you do not want TPM functionality for your user domain simply -leave out the ''vtpm'' line in the configuration file. +Next, launch the Linux guest +# xl create -c /home/user/domu/domu.cfg -Running the TPM: ----------------- +If xen-tpmfront was compiled as a module, be sure to load it +in the guest. -To run the vTPM, the device /dev/vtpm must be available. -Verify that ''ls -l /dev/vtpm'' shows the following output: +# modprobe xen-tpmfront -crw------- 1 root root 10, 225 Aug 11 06:58 /dev/vtpm +After the Linux domain boots and the xen-tpmfront driver is loaded, +you should see the following on the vtpm console: -If it is not available, run the following command as ''root''. -mknod /dev/vtpm c 10 225 +Info: VTPM attached to Frontend X/Y -Make sure that the vTPM is running in domain 0.

See docs/misc/vtpm.txt for details on the +vTPM subsystem as a whole. + + +------------------------------ +OPERATION +------------------------------ + +The vtpm-stubdom is a mini-OS domain that emulates a TPM for the guest OS to +use. It is a small wrapper around the Berlios TPM emulator +version 0.7.4. Commands are passed from the linux guest via the +mini-os TPM backend driver. vTPM data is encrypted and stored via a disk image +provided to the virtual machine. The key used to encrypt the data along +with a hash of the vTPM''s data is sent to the vTPM manager for secure storage +and later retrieval. The vTPM domain communicates with the manager using a +mini-os tpm front/back device pair. + +------------------------------ +COMMAND LINE ARGUMENTS +------------------------------ + +Command line arguments are passed to the domain via the ''extra'' +parameter in the VM config file. Each parameter is separated +by white space. For example: + +extra="foo=bar baz" + +List of Arguments: +------------------ + +loglevel=<LOG>: Controls the amount of logging printed to the console. + The possible values for <LOG> are: + error + info (default) + debug + +clear: Start the Berlios emulator in "clear" mode. (default) + +save: Start the Berlios emulator in "save" mode. + +deactivated: Start the Berlios emulator in "deactivated" mode. + See the Berlios TPM emulator documentation for details + about the startup mode. For all normal use, always use clear + which is the default. You should not need to specify any of these. + +maintcmds=<1|0>: Enable to disable the TPM maintenance commands. + These commands are used by tpm manufacturers and thus + open a security hole. They are disabled by default. + +hwinitpcr=<PCRSPEC>: Initialize the virtual Platform Configuration Registers + (PCRs) with PCR values from the hardware TPM. Each pcr specified by + <PCRSPEC> will be initialized with the value of that same PCR in TPM + once at startup. By default all PCRs are zero initialized. + Value values of <PCRSPEC> are: + all: copy all pcrs + none: copy no pcrs (default) + <N>: copy pcr n + <X-Y>: copy pcrs x to y (inclusive) + + These can also be combined by comma separation, for example: + hwinitpcrs=5,12-16 + will copy pcrs 5, 12, 13, 14, 15, and 16. + +------------------------------ +REFERENCES +------------------------------ + +Berlios TPM Emulator: +http://tpm-emulator.berlios.de/ diff --git a/stubdom/vtpmmgr/README b/stubdom/vtpmmgr/README new file mode 100644 index 0000000..09f3958 --- /dev/null +++ b/stubdom/vtpmmgr/README @@ -0,0 +1,75 @@ +Copyright (c) 2010-2012 United States Government, as represented by +the Secretary of Defense.

See docs/misc/vtpm.txt for details on the +vTPM subsystem as a whole. + + +------------------------------ +OPERATION +------------------------------ + +The vtpmmgrdom implements a vTPM manager who has two major functions: + + - Securely store encryption keys for each of the vTPMS + - Regulate access to the hardware TPM for the entire system + +The manager accepts commands from the vtpm-stubdom domains via the mini-os +TPM backend driver. The vTPM manager communicates directly with hardware TPM +using the mini-os tpm_tis driver. + + +When the manager starts for the first time it will check if the TPM +has an owner. If the TPM is unowned, it will attempt to take ownership +with the supplied owner_auth (see below) and then create a TPM +storage key which will be used to secure vTPM key data. Currently the +manager only binds vTPM keys to the disk. In the future support +for sealing to PCRs should be added. + +------------------------------ +COMMAND LINE ARGUMENTS +------------------------------ + +Command line arguments are passed to the domain via the ''extra'' +parameter in the VM config file. Each parameter is separated +by white space. For example: + +extra="foo=bar baz" + +List of Arguments: +------------------ + +owner_auth=<AUTHSPEC>: Set the owner auth of the TPM. The default + is the well known owner auth of all ones. + +srk_auth=<AUTHSPEC>: Set the SRK auth for the TPM. The default is + the well known srk auth of all zeroes. + The possible values of <AUTHSPEC> are: + well-known: Use the well known auth (default) + random: Randomly generate an auth + hash: <HASH>: Use the given 40 character ASCII hex string + text: <STR>: Use sha1 hash of <STR>. + +tpmdriver=<DRIVER>: Which driver to use to talk to the hardware TPM. + Don''t change this unless you know what you''re doing. + The possible values of <DRIVER> are: + tpm_tis: Use the tpm_tis driver to talk directly to the TPM. + The domain must have access to TPM IO memory. (default) + tpmfront: Use tpmfront to talk to the TPM. The domain must have + a tpmfront device setup to talk to another domain + which provides access to the TPM. + +The following options only apply to the tpm_tis driver: + +tpmiomem=<ADDR>: The base address of the hardware memory pages of the + TPM (default 0xfed40000). + +tpmirq=<IRQ>: The irq of the hardware TPM if using interrupts. A value of + "probe" can be set to probe for the irq. A value of 0 + disabled interrupts and uses polling (default 0). + +tpmlocality=<LOC>: Attempt to use locality <LOC> of the hardware TPM. + (default 0) -- 1.7.10.4

I''d already done all the autoconf faff and updated .*ignore for you (adding autom4te.cache, config.log and config.status as appropriate). So rather than resending please could you provide an incremental fix against: git://xenbits.xen.org/people/ianc/xen-unstable.git vtpm I''ll then merge that into the appropriate patch. It also occurs to me that this series introduces a little bisection blip where cmake will be required (i.e. from patch 3 until here). The right way to do this would have been to put the patch introducing autoconf at the start. I''m inclined to just gloss over that for now, but if you feel so inclined you could reorder things.> --- > autogen.sh | 2 + > config/Stubdom.mk.in | 45 ++++++++++++++++ > {tools/m4 => m4}/curses.m4 |

I would recommend reordering things, yes.
If the bisection blip bites us, what will happen is that the automatic
bisector will finger the cmake-requiring changeset. Normally if that
happens it would be fair to ask the person who introduces the
bisection breakage to debug whatever the other problem is that the
bisector is hunting for. I wouldn''t recommend knowingly putting
oneself in that position :-).
Ian.
Ok, just for reference for now, Nothing has changed with the vtpm patches, just the autoconf stuff is evolving. -----Original Message----- From: Ian Campbell [mailto:Ian.Campbell@citrix.com] Sent: Thursday, December 13, 2012 6:48 AM To: Fioravante, Matthew E.

The original stubdom makefile did not include it as a build target but my configure.ac erroneously enables it by default. The multiple definition problem occurs because like c-stubdom its minios.cfg enables CONFIG_TEST which defines a main function. It also defines a main function for itself.

That way if someone does does a make or a make install in stubdom before autoconf they won''t hit the cmake dependency.> >> --- >> autogen.sh | 2 + >> config/Stubdom.mk.in | 45 ++++++++++++++++ >>
