[Xen-devel] vTPM NVM, loadkey and trousers questions

Hi everyone,

I am using Xen 3.2.1 with the vtpm-12-patch.diff patch posted in [0]. My TPM is
an Infineon 1.2. In total I have got three different questions:

1. NVM loading problem at VM creation
When I am creating a VM the last few lines of the vtpm_manager output are:
TPMD[245]: tpm/tpm_startup.c:45: Info: TPM_Startup(1)
Loading NVM.
        Sending LoadNVM command
ERROR[VTPM]: Failed to load NVM
.INFO[VTPM]: [VTPM Listener]: VTPM Listener waiting for messages.
        Reading LoadNVM header

For every VM a new tpmd instance is created, ignoring the setting in my VM
config file. In /var/vtpm are only two folders (fifos, socks) and two files
(VTPM, vtpm.db). I am missing the one for non volatile memory. Any ideas what
might be wrong here?


2. Using IAIK jTSS in VM (http://trustedjava.sourceforge.net/)
I want to use the jTSS in my VMs. Some simple operations like taking ownership,
extending a PCR and creating keys are working, but there seems to be a problem
when it comes to loading keys.
For example, if I try to bind data after taking ownership using the jtpmtools
example (jtt.sh bind) the operation fails. Java stack trace is:
iaik.tc.tss.api.exceptions.tcs.TcTpmException: 

TSS Error:
error layer:                0x00 (TPM)
error code (without layer): 0x1f
error code (full):          0x1f
error message: An IO error occurred transmitting information to the TPM

        at
iaik.tc.tss.impl.java.tcs.pbg.TcTpmCmdCommon.handleRetCode(TcTpmCmdCommon.java:73)

iaik.tc.tss.impl.java.tcs.pbg.TcTpmCmdDeprMisc.TpmLoadKey(TcTpmCmdDeprMisc.java:222)

        at
iaik.tc.tss.impl.java.tcs.tcsi.TcTcsi.TcsipLoadKeyByBlob(TcTcsi.java:535)

A lot of vtpm_manager output is produced. The last few lines are:
TPMD[6]: tpm/tpm_cmd_handler.c:4162: Debug: tpm_handle_command()
TPMD[6]: tpm/tpm_cmd_handler.c:3466: Debug: [TPM_TAG_RQU_AUTH1_COMMAND]
TPMD[6]: tpm/tpm_cmd_handler.c:3654: Debug: [TPM_ORD_LoadKey]
TPMD[6]: tpm/tpm_storage.c:526: Info: TPM_LoadKey()
TPMD[6]: tpm/tpm_storage.c:528: Debug: [ parentHandle=40000000 ]
TPMD[6]: tpm/tpm_cmd_handler.c:4117: Info: TPM command succeeded
ERROR[VTPM]: [Backend Listener]: Error reading from DMI. Aborting... 
INFO[VTPM]: [Backend Listener]: Backend Listener waiting for messages.

Let me know, if you need the whole output. From my understanding it says
"TPM command succeeded". What''s the matter with "Error
reading from DMI"? On my real TPM the command is working.

I also tried a self written application using jTSS. When trying to load a key
vtpm_managers output finishes with:
TPMD[1]: tpm/tpm_cmd_handler.c:4162: Debug: tpm_handle_command()
TPMD[1]: tpm/tpm_cmd_handler.c:3466: Debug: [TPM_TAG_RQU_AUTH1_COMMAND]
TPMD[1]: tpm/tpm_cmd_handler.c:3654: Debug: [TPM_ORD_LoadKey]
TPMD[1]: tpm/tpm_storage.c:526: Info: TPM_LoadKey()
TPMD[1]: tpm/tpm_storage.c:528: Debug: [ parentHandle=40000000 ]
TPMD[1]: tpm/tpm_cmd_handler.c:4110: Info: TPM command failed: (0x0c) The key
handle presented was invalid.
TPMD[1]: tpm/tpm_eviction.c:56: Info: TPM_FlushSpecific()
TPMD[1]: tpm/tpm_eviction.c:57: Debug: [ handle=02000000 resourceType=00000002 ]
TPMD[1]: tpmd.c:227: Debug: Sent[14]: 0 0 0 1 0 c4 0 0 0 a 0 0 0 c 

INFO[VTPM]: [Backend Listener]: Sending DMI''s response to guest.
INFO[VTPM]: [Backend Listener]: Backend Listener waiting for messages.

Again this program is running well on a real TPM and I created the key which is
tried to load before.


3. Trousers 0.2.9
IAIK provides a java wrapper to use the TPM. Unfortunately this is only working
with trousers version 0.2.9. Using trousers 0.3.1 the tpm tools like tpm_version
are working. But as mentioned, the wrapper is only compatible with 0.2.9.
Using that version (no matter if I apply IFX patch or not) the result of
tpm_version is:
Tspi_Context_Connect failed: 0x00003004 - layer=tsp, code=0004 (4), Internal
software error
TCSD''s output:
TCSD svrside.c:272 accepted socket 6
TCSD tcsd_threads.c:225 Rx''d packet
TCSD tcsd_wrap.c:4060 Dispatching ordinal 1
TCSD tcsd_wrap.c:366 thread b7c7eb90 servicing a tcs_wrap_OpenContext request
TCSD tcsd_threads.c:252 Sending 0x21 bytes back
TCS tcs_utils.c:1317 Socket connection closed.
TCSD tcsd_threads.c:264 Thread exiting.
TCS tcscm.c:40 Closing context A0907600
TCS tcscm.c:52 Context A0907600 closed

When I start tcsd the following output appears:
TDDL tddl.c:105 Calling write to driver
TDDL tddl.c:116 ioctl: (25) Inappropriate ioctl for device
TDDL tddl.c:117 Falling back to Read/Write device support.

Does anyone know if 0.2.9 is just outdated or should it be working and there is
something else wrong?

Any hints are very welcome!

Thanks in advance
Tim

Re: [Xen-devel] vTPM NVM, loadkey and trousers questions

Hi

See post in [0] about loading keys into vTPM on infineon 1.2 TPMs. IMO, 
you also need this patch.

Could you send any progress about this NVM issue. This is one of my 
biggest problems in vTPM and I want to see if anyone gets it work.

Thank you
Erdem Bayer

Hi Erdem,

thanks for your reply.

Are you using Xen 3.1.x yet? I am pretty sure the patch you mentioned is
included in Xen 3.2.1.

I will definitely keep you posted on any progress concerning this.
