The following are the final set of patches for vtpm in xen.
They are derived from the previous v7 and Ian's xen
vtpm respository with the various minor bug fixes we
have discussed and fixed along the way. The bug fixes
are baked into their respective patches.
Matthew Fioravante (8):
add vtpm-stubdom code
add stubdom/vtpmmgr code
vtpm/vtpmmgr and required libs to stubdom/Makefile
Add vtpm documentation
README: Add cmake dependency
stubdom: Add autoconf
Add a top level configure script
Add conditional build of subsystems to configure.ac

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 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 -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.

In the stubdom/Makefile we define TPM_NO_EXTERN using cmake to build the tpm emulator. In tpm_emulator-x86_64/tpm/tpm_emulator_extern.c all of the functions defined there use open() and mkdir() etc.. However when TPM_NO_EXTERN is defined this file contains only a set of null initialized function pointers (which vtpm assigns to its own functions). Using the standard make targets there should be no possible way to get the tpm emulator to build without TPM_NO_EXTERN. When cmake is not present make vtpm-stubdom will fail because vtpm-stubdom is not present in the TARGETS variable. I certainly was not able to reproduce it in xen-unstable or in staging using a variety or permutations of make targets and cmake present/not-present. Were you playing with building the tpm emulator manually? Anyway I'm confident that if you do a distclean and rebuild the error should go away. Unless there is something broken about the clean targets leaving things around that should be deleted.

There is however a bug if you try to do make cross-tpmemu with cmake not installed. It creates tpm_emulator-$(ARCH) but doesn't run cmake, screwing up the make rules that expect this directory to exist. I'm creating a fix now to do a check and abort early. Still, this bug doesn't cause the linker error you've given, it only causes tpm emulator to fail to build. >> lseek and open are defined in extras/mini-os/lib/sys.c but: >> $ nm stubdom/mini-os-x86_64-vtpm/lib/sys.o | egrep T.\(open\|lseek\) >> 0000000000002456 T lseek64 >> 0000000000002a4e T open64 >> >> Perhaps some sort of -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE mismatch >> between the libc and the app libraries? >> >> Not sure about the __errno_location one other than: >> >> $ grep -B2 __errno_location stubdom/caml/main-caml.c >> /* Ugly binary compatibility with Linux */ >> FILE *_stderr asm("stderr"); >> int *__errno_location; >> >> Everything else seems to build ok. so without cmake installed it works >> fine. >> >>> Matthew Fioravante (8): >>> add vtpm-stubdom code >>> add stubdom/vtpmmgr code >>> vtpm/vtpmmgr and required libs to stubdom/Makefile >>> Add vtpm documentation >>> README: Add cmake dependency >>> stubdom: Add autoconf >>> Add a top level configure script >>> Add conditional build of subsystems to configure.ac >> Ian. >> > [-- Attachment #1.2: S/MIME Cryptographic Signature --] [-- Type: application/pkcs7-signature, Size: 1459 bytes --] [-- Attachment #2: Type: text/plain, Size: 126 bytes --] _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel ^ permalink raw reply [flat|nested] 32+ messages in thread

No, my script just runs configure + make dist -j12. > Anyway I'm confident that if you do a distclean and rebuild the error > should go away. Unless there is something broken about the clean targets > leaving things around that should be deleted. My standard test script includes both a distclean and a "git clean -f -dx" which results in a pristine build tree. e.g. : $ ls stubdom/ c/ newlib-chk.patch caml/ newlib.patch grub/ newlib-stdint-size_max-fix-from-1.17.0.patch grub.patches/ ocaml.patch ioemu-minios.cfg pciutils.patch libpci.config.h README libpci.config.mak stubdom-dm lwip.patch-cvs xenstore-minios.cfg Makefile > Can you try one more time with cmake installed? I have just rerun: $ make distclean -j12 -s $ git clean -f -dx $ cmake --version cmake version 2.8.2 $ ./configure $ make dist-stubdom -j12 Same result. This is from a totally clean tree. I have pushed it to git://xenbits.xen.org/people/ianc/xen-unstable vtpm4 in case there is some sort of patch misapplication. I've just rerun again but this time doing "make -C stubdom vtpm-dom -j12" at the end. The complete log of the configure+make stage of that is attached. $ ( ./configure && make -C stubdom/ vtpm-stubdom -j12 ) 2>&1 | tee vtpm-build.log Interesting lines: cd tpm_emulator-x86_64/build; /usr/bin/cmake .. -DCMAKE_C_COMPILER=gcc -DCMAKE_C_FLAGS="-std=c99 -DTPM_NO_EXTERN \ -isystem /local/scratch/ianc/devel/committer.git/stubdom/../extras/mini-os/include [....] so TPM_NO_EXTERN is there but: cd /local/scratch/ianc/devel/committer.git/stubdom/tpm_emulator-x86_64/build/tpm && /usr/lib/ccache/gcc -I/opt/local/include -I/local/scratch/ianc/devel/committer.git/stubdom/tpm_emulator-x86_64 -I/local/scratch/ianc/devel/committer.git/stubdom/tpm_emulator-x86_64/build -Wall -Werror -Wno-unused-parameter -Wpointer-arith -Wcast-align -Wwrite-strings -Wextra -o CMakeFiles/tpm.dir/tpm_emulator_extern.o -c /local/scratch/ianc/devel/committer.git/stubdom/tpm_emulator-x86_64/tpm/tpm_emulator_extern.c IOW the TPM_EXTERN stuff has disappeared.

Ok I think that’s the bug. It looks like the default value of BUILD_TYPE is dependent on the compiler. Can you try changing the line in stubdom/Makefile to do -DCMAKE_C_FLAGS_RELEASE=<stuff> and and add -DCMAKE_BUILD_TYPE=Release.

Yes that’s what I meant. One more thing to try. Keep the BUILD_TYPE but set CMAKE_C_FLAGS_RELEASE back to CMAKE_C_FLAGS.
