Hey there @danglus. A couple things: First is that the tpmclient
should be run against the TPM2 simulator only. We haven't been particularly clear about this in the past but I updated the README file this week to clear this up. Second is some debugging tips: in the tpm2.0-tools repo there's a tool called tpm2_rc_decode
which should help out decoding those hex response codes you're getting.
Ignoring the tpmclient
failure for the time being...
The error you're getting from the tpm2.0-tool is 0x101 which decodes to:
flihp@lappy:~/tpm2.0-tools$ src/tpm2_rc_decode 0x101
error layer
hex: 0x0
identifier: TSS2_TPM_ERROR_LEVEL
description: Error produced by the TPM
format 0 error code
hex: 0x01
name: TPM_RC_FAILURE
description: commands not being accepted because of a TPM failure
So this looks like the TPM on that platform is reporting that the TPM has failed in some way and is now refusing to accept commands. Yipes! I've never seen this before personally.
Generally the first thing I'd recommend is checking for a firmware update on that platform. Do you know if that system has a discrete TPM or PTT? I'd also recommend you retry running the tpm2.0-tools commands after you power cycle the system. It could be that the execution of tpmclient
before running the tools put the TPM into some weird state.
Yes, this NUC has a "Discrete trusted platform module (TPM v2.0). I updated the BIOS and power cycled the NUC, but problem persists (we even jumpered the TPM - just in case).
Was this library tested on HW TPMs? if so, do you know which brands?
I've only ever tested the TSS against Intel's PTT and the Infineon TPM. Have you been able to perform simple operations like query the TPM for capabilities? This is where I would start, simple metadata queries. Then move on to stuff like key creation & usage.
Can you grab the tpm2_dump_capability
and see if you can at least get your TPM to dump info about its current state / supported capabilities?
Thanks Philip,
1) According to its datasheet, the TPM in this NUC is an Infineon SLB9665TT2.0 TPM version 2.0
2) The tpm2.0 tools that I pulled from github doesn’t include a tpm2_dump_capability, basically here are the commands that it has:
~/tpm/tpm2.0-tools/src# tpm2_ tpm2_activatecredential tpm2_getmanufec tpm2_listpersistent tpm2_nvreadlock tpm2_rsaencrypt tpm2_akparse tpm2_getpubak tpm2_load tpm2_nvrelease tpm2_sign tpm2_certify tpm2_getpubek tpm2_loadexternal tpm2_nvwrite tpm2_takeownership tpm2_create tpm2_getrandom tpm2_makecredential tpm2_quote tpm2_unseal tpm2_createprimary tpm2_hash tpm2_nvdefine tpm2_rc_decode tpm2_verifysignature tpm2_encryptdecrypt tpm2_hmac tpm2_nvlist tpm2_readpublic tpm2_evictcontrol tpm2_listpcrs tpm2_nvread tpm2_rsadecrypt
3) The simplest thing that I could think of was to get a random value – which seems to work: root@optn36:~/tpm/tpm2.0-tools/test# tpm2_getrandom -s 256 -o out.random
GetRandom succ... byte size: 32 0xA4 0xB2 0xA6 0xF3 0x4F 0x01 0x84 0xA0 0x10 0xE7 0x53 0x61 0x1A 0xCF 0x65 0x8F 0x4A 0x42 0x55 0x23 0xC6 0xC6 0x4B 0x51 0x55 0xE9 0xAE 0xDB 0x1A 0xDA 0x98 0x2D
4) But still, whenever I try to create a primary key, I’m getting the same error message:
CreatePrimary Succeed ! Handle: 0x80000000
......ContextSave:Save handle 0x80000000 context failed. TPM Error:0x101......
Thanks, Dan

Ah sounds like you're using a packaged version of the TSS & tools?. To get the tpm2_dump_capability
tool you'll need to pull from the tools project git and build from source. Having the data produced by this tool will give us a better understanding of the TPM (manufacturer data, version numbers for the firmware etc). Also building from the latest git for both tools will rule out a bug that may have been fixed since the release your package is built from. No guarantees this will fix the issue but it's the lowest effort test we can do.
Actually, I built the tools from source, but I pulled them a long time ago. Anyway, I pulled again, and here is the dump: TPMA_CC: 0x0440011f commandIndex: 0x11f reserved1: 0x0 nv: set extensive: clear flushed: clear cHandles: 0x2 rHandle: clear V: clear Res: 0x0 TPMA_CC:

Ah sounds like you're using a packaged version of the TSS & tools?. To get the tpm2_dump_capability tool you'll need to pull from the tools project git and build from source. Having the data produced by this tool will give us a better understanding of the TPM (manufacturer data, version numbers for the firmware etc). Also building from the latest git for both tools will rule out a bug that may have been fixed since the release your package is built from. No guarantees this will fix the issue but it's the lowest effort test we can do.

The failure you're seeing with the createprimary
tool doesn't look like it's related to the actual creation of the primary key. Looks like it's failing to save the context of the transient object. The tools do this so you can use the key in future commands.
Are you able to execute this command against the software simulator?
Probably a good idea to hack up a quick integration test that does a simple key creation, context save and context flush.
Hi, 1) Yes, it works fine against the IBM simulator, even on the same machine. 2) I'm getting the same error on the two NUCs that I have. 3) it takes the command 17 seconds to fail: root@frc-nuc:~/tpm/tpm2.0-tools/test# time tpm2_createprimary -A n -g 0xB -G 0x1 -C primary.ctx nameAlg = 0x000b type = 0x0001 contextFile = primary.ctx

real 0m17.435s user 0m0.000s sys 0m0.000s root@frc-nuc:~/tpm/tpm2.0-tools/test#
4) when running a successful command, like: tpm2_getrandom -s 16 -o rnd.txt The resoruce manager dumps the following
Accept socket: 0x9 Accept socket: 0x8 Resource Manager TPM CMD Server accepted client Resource Manager Other CMD Server accepted client In rmRecvBytes, recv failed (socket: 0x8) with error: 0 TpmCmdServer died (TPM CMD), rval: 0x000a000a, socket: 0x8. In rmRecvBytes, recv failed (socket: 0x9) with error: 0 OtherCmdServer died (Other CMD), socket: 0x9.
This happens in about 100ms. I wonder why it says "In rmRecvBytes, recv failed" because the command return a valid value: root@frc-nuc:~/tpm/tpm2.0-tools/test# time tpm2_getrandom -s 16 -o rnd.txt byte size: 16 0x98 0x13 0xFB 0x26 0x72 0x09 0x3A 0x97 0x41 0x8A 0xFB 0xFF 0xD3 0xD7 0xF5 0xAB
real 0m0.163s user 0m0.000s sys 0m0.000s
However for the faulty createprimary command, it first dumps:
Accept socket: 0x7 Resource Manager Other CMD Server accepted client Accept socket: 0x6 Resource Manager TPM CMD Server accepted client
and then after the 17 seconds:
In rmRecvBytes, recv failed (socket: 0x7) with error: 0 OtherCmdServer died (Other CMD), socket: 0x7. In rmRecvBytes, recv failed (socket: 0x6) with error: 0 TpmCmdServer died (TPM CMD), rval: 0x000a000a, socket: 0x6.
BTW, why did you recommend to 'hack up a quick integration test'? do you suspect that tpm2_tools is doing something wrong?
Anyway, I'll have time tomorrow to try new staff.
Thanks, Dan
Under normal circumstances a TPM should never respond with TPM_RC_FAILURE. What you're seeing here is probably a bug in the firmware of your TPM. When you see the error with tpm2_createprimary, could you also try to create an ECC key (-G 0x23) instead?
Hi Alex, From what I can see, this error is not coming from the TPM but from the resourceMgr itself. When I run: “tpm2_createprimary -A n -g 0xB -G 0x1 -C primary.ctx”
The EvictContext() function is called twice. Unfortunately, when the HW TPM is in use, on the 2nd call, FindEntry return TSS2_RC_SUCCESS but: foundEntryPtr->status.loaded is false which cause the EvictContext() to fail (return 0xC1000), and this what causes the overall return val to be 0x101.
TSS2_RC EvictContext(TPM_HANDLE virtualHandle) { TSS2_RC rval = TSS2_RC_SUCCESS; RESOURCE_MANAGER_ENTRY_PTR foundEntryPtr;
// Find entry corresponding to this virtual handle.
rval = FindEntry( entryList, RMFIND_VIRTUAL_HANDLE, virtualHandle, &foundEntryPtr);
printf("dangl: resourcemgr.c:906/EvictContext/FindEntry(virtualHandle=%X): rval=%X\n",virtualHandle,rval);
if( rval != TSS2_RC_SUCCESS )
return rval;
ENABLE_RM_TPM_CMD_DEBUG_MSGS;
if( foundEntryPtr->status.loaded )
{
…
}
else
{
SetRmErrorLevel( &rval, TSS2_RESMGRTPM_ERROR_LEVEL );
}
Any ideas?
Thanks, Dan

@danglus : Given all of the data I'm inclined to agree with @webmeister. The response code 0x101 should only be returned by your TPM, and it indicates an internal error (aka a bug in the TPM).
No guarantees that we're right though. The best way to test this theory is to remove the resourcemgr from your configuration. This can be done using the dynamic TCTI mechanism recently introduced to the tpm2.0-tools project. Each tool now accepts command line options that allow it to instantiate either the socket or the device TCTI. The socket interface is the default, but you can use the device TCTI to communicate directly with the TPM device driver (removing the resourcemgr from the equation).
Oh, this is interesting.
root@frc-nuc:~/tpm/tpm2.0-tools# tools/tpm2_createprimary -T device -A n -g 0xB -G 0x1 -C primary.ctx nameAlg = 0x000b type = 0x0001 contextFile = primary.ctx
CreatePrimary Succeed ! Handle: 0x80000000
But it now fails when I try it again:
root@frc-nuc:~/tpm/tpm2.0-tools# tools/tpm2_createprimary -T device -A n -g 0xB -G 0x1 -C primary.ctx nameAlg = 0x000b type = 0x0001 contextFile = primary.ctx

But now you get a different error code: TPM_RC_VALUE, which usually indicates an invalid command parameter. And according to the message, it is already the CreatePrimary call that fails, whereas before it failed in the ContextSave step.
@flihp: Is there an easy way to dump the commands and responses on their way to/from the TPM? Such a log would make it easier to see which commands are executed and why they fail. --debugLevel does not seem to have any effect for me.
Debug flags need to be enabled at build time. All of the necessary flags are collected in a CONFIG_SITE file here: https://github.com/01org/TPM2.0-TSS/blob/master/lib/debug_config.site The INSTALL file has instructions / examples showing the use of the CONFIG_SITE file here: https://github.com/01org/TPM2.0-TSS/blob/master/INSTALL#L67
The debug output you'll get will include full dumps of the buffers as they pass though the resourcemgr.
@webmeister Just realized that your reference to debugLevel was an option that the resourcemgr / test code is expected to understand. Unfortunately, AFAIK, that option never did anything :frowning_face: I'm in the process of re-implementing a lot of functionality and the debug interfaces are part of that.

So, when using the '-T option' I can use the TPM. I had less luck when I tried to use context files (but maybe I'm not doing it right). From what I can see, context saving is also problem when I'm using the resorucemgr. From what I can see the problem is with the EvictContext() function (and not an error returned by the TPM).
BTW, is there a way for to run the resorucemgr in a debugger? (it is a bash script an not an executable so I've no idea how to do it).
Again, any idea will be appreciated (if possible from your side, we could even try to schedule on online debug session).
Thanks, Dan
@flihp, @webmeister : we tried to use the TPM using Microsoft's TSS.MSR.NET on Windows10 and it worked (even with context).
@danglus : Glad you're making progress. Using the device TCTI means you don't have to rely on saving / loading contexts since the resourcemgr won't be flushing transient objects when the tpm2.0-tools programs exit. This is a reasonable short term work-around but there's still a bug: the tools should be able to save / restore context files.
Let me circle back with the folks over at the tpm2.0-tools project to see if we can "root cause" this one.
Sorry, joining this party late. Here is my output executing tpm2_createprimary repeatedly. In summary I am not seeing create primary error.

@idesai: Could you run those commands in a loop, to ensure it does not fail after multiple tries? Also, what TPM (vendor/firmware version) do you use?
Are you creating a primary key using the same template under the same hierarchy in a tight loop? You would always arrive at the same key, what is the use case? My test was on a skylake with Intel Platform Trust Technology (PTT), Intel's integrated TPM2.0 solution.
Looped for about 10 minutes now, no errors yet.
Still going no errors yet.
Hi, I managed to write my own code, that can do ContextSave and ContextLoad with the TPM in this NUC. Anyway, given that the resorucemgr is going thought a major re-write, I think that we can close this ticket.
Thanks! Dan
Hey Dan. I've got one of these NUCs on order. Should land here in the next few days. Will try to repro when I have the hardware.
This is great!
Two comments:
1) Using the SAPI commands directly, I’m now able to create primary keys, RSA keys as well as save/load and flash context.
2) I got the following response from Infineon support:
“According to the github link and the corresponding description, the device is a SLB 9665 FW5.40: TPM_PT_FIRMWARE_VERSION_1: 0x00050028 indicates FW V5.40
The issue is described as known issue in the errata sheet: 3.3.5.3 Context management issue for RSA primary keys Long sequences of TPM2_ContextSave / TPM2_ContextLoad for RSA primary keys may cause the TPM to return TPM_RC_FAILURE in TPM2_ContextLoad. So RSA primary key context is rejected.
With the next FW version, e.g. FW5.51 the issue has been fixed.” So, maybe, the resourcemgr failing because of a FW bug afterall. Anyway, I’ll try to update the TPM FW to see if it solves the resourcemgr problem.
Regards, Dan
@flihp have received that NUC device?
I have a problem which I wasn't able to solve with Intel Support. The TPM on this NUC is installed with an old TPM version (5.40) that has few known bugs. Anyway, I got an update package from Infineon - but I can't install it because it only work with NULL platform password (and, apparently, Intel has changed it).
Thanks, Dan
@danglus did they provide a link to their site for it? I'd be interested in whatever they've given as I have one of those systems.
Well, this is a real issue. I got the update from Infineon, but I can't install it on the NUC's TPM because the platform password is not NULL. I have a very long discussion with Intel support about it, they asked me to install all kind of, unfortunately, unrelated Windows only update packages which didn't help. Additionally, so far they were reluctant to escalate this problem to higher support tiers.
@flihp, as an Intel employee, and an owner of one of those NUC any chance you could help here? (my ticket number Case #: 02977336 [ ref:_00DU0YT3c._5000Pc4utz:ref ]).
Let me ask around a bit. Not sure how this stuff works TBH. Not sure where to start asking really.
@danglus Typically platform hierarchy authorization is set to a random value at startup by early boot code. Start with information on BIOS: vendor, version, tpm configuration options, etc. Does infineon provide an EFI application to update firmware by any chance?
@danglus there is infact an EFI update utility from infineon. See issue #270. PS: What coincidence that the tool was referenced by @musakontron on Oct 6th (today) last year :) fs1:\TPMUpdate> TPMFactoryUpd.efi -update tpm20-emptyplatformauth -firmware TPM20_5.51.2098.0_to_TPM20_5.60.2677.0.BIN
To update the Infineon SLB9665 firmware on our boards (I am a BIOS dev for ericsson HDS8000 CSU01 implementation of the Intel RiverForest platform Intel LongBrook CRB based chipset port from Insyde software), I first have to run the Intel TXT provisioning tools script "ResetPlatformAuth sha256 TopSecret" from the UEFI shell to reset the Platform Authority to the “Empty Buffer”, but that needs the bunch of TXT provisioning files "TopSecret" (*.hash , .pdef . .idef . .wpdef etc), which are derived from the Insyde provided example provisioning files which I think are based on the Intel TXT provisioning files from the IBP (Intel Business Portal) doc#542298 TPM2ProvTool v0.7 , with the policy digest changed for our boards...
Thanks for the info @gregelkin, any chance the tools you're referring to are available to the public? Can you provide links?
The Infineon firmware update tool needs the Platform Hierarchy (policy to be satisfied? value is randomised by BIOS code?) to be in the "empty buffer" state, which I've achieved before for my platform by the TXT provisioning tool ResetPlatformAuth script with the policy/hash definition files that match the policy/hash in our BIOS. So even if the Intel provisioning tool/script were in public domain, it's unlikely that the definition files to match the customers BIOS PlatformHierarchy policy would be available to the public? I don't know what other way to get the Platform Hierarchy policy satisfied for the Infineon tool to let the firmware update work. It's a bit of a mess to be honest...
some links at https://www.intel.com/content/www/us/en/embedded/products/grantley-refresh/software-and-drivers.html whose download require an Intel "resource and design center" account registration & CNDA, but I also note that doc#542298 now says the tools/example provisioning scripts & definitions (which I got 2+ years ago from there) are in CDI/IBL# 563989 and that I can't see outside of my IBP account anywhere.
I think flashing the firmware on these chips is about to get a lot more relevant: https://arstechnica.com/information-technology/2017/10/crypto-failure-cripples-millions-of-high-security-keys-750k-estonian-ids/
Hi, I'm trying to use the TPM2.0-TSS on an Intel's NUC that has a TPM http://www.intel.com/content/www/us/en/nuc/nuc-kit-nuc5i3myhe-board-nuc5i3mybe.html). The NUC is running Ubuntu.
Anyway, after installing few missing packages, I managed to make the library.
