[Trustedjava-support] Unable to open TPM device file /dev/tpm0 through Trusted JAVA

[waqar a. <afr...@gm...>]

Hello Dear List

I am using Trusted JAVA to Extend a byte array to the PCR 11 of the TPM but
when I do I get the Following Error:

===========================================================================================

The Part of Code for PCR Extending is:

===========================================================================================

    int pcrIndex = 11;
    byte[] byteData = xmlFromNode.getBytes();

    TcBlobData data = TcBlobData.newByteArray(byteData);

    try

        TcTssAbstractFactory factory = new TcTssLocalCallFactory();
        TcIContext context = factory.newContextObject();

        context.connect("localhost");
        TcITpm tpm = context.getTpmObject();
        TcTssPcrEvent event = new TcTssPcrEvent();
        event.setPcrIndex(pcrIndex);
        event.setEventType(TcTssConstants.TSS_EV_PLATFORM_SPECIFIC);

event.setVersionInfo(tpm.getCapabilityVersion(TcTssConstants.TSS_TPMCAP_VERSION,
null));
//      event.setEvent(TcBlobData.newString(logEntry));

        TcBlobData oldPcrContent = tpm.pcrRead(pcrIndex);

        try

        }

        catch (TcTssException e)
        {
            if (e.getErrCode() == TcTssErrors.TSS_E_NOTIMPL)
            {
                System.out.println("\n\nNote: This TSS has no event log
support\n\n");
            }
            else
            {
                throw e;
            }
        }

        context.closeContext();

        System.out.println("\n\nExtendPcr succeeded\n\n");

        if (event != null)
        {
            TcBlobData newPcrContentPlain = TcBlobData.newUINT32(pcrIndex);
            newPcrContentPlain.append(data.sha1());

newPcrContentPlain.append(TcBlobData.newUINT32(event.getEventType()));
            newPcrContentPlain.append(event.getEvent());
            oldPcrContent.append(newPcrContentPlain.sha1());
        }
        else
        {
            oldPcrContent.append(data.sha1());
        }
            System.out.println("expected new content of PCR " + pcrIndex +
": "
                    + oldPcrContent.sha1().toHexStringNoWrap());

    }
    catch (TcTssException e)
    {
        if (e.getErrLayer() == TcTssErrors.TSS_LAYER_TPM)
        {
            System.out.println("can't extend this pcr - wrong locality");
        }
        else
        {
            System.out.println("Error");
        }
        }
    }

===========================================================================================

I tried with both Hardware TPM and TPM Emulator but still getting the Error,
The above Error is of Software TPM (Both Error messages are exactly the Same
just for hardware TPM its tpm0)

Any Idea or Hint what could be the Problem?

Thanx in Advance

Hello,

What's your platform? How did you configure the jTSS TCS and are there 
any other TSSes installed?

Re: [Trustedjava-support] Unable to open TPM device file /dev/tpm0 through Trusted JAVA

[waqar a. <afr...@gm...>]

I was about to reply, I have Fixed the problem, Actually the TPM was in use
by the Trousers, Fedora 14 had it installed by default which i didn't know,
Stopping it solved the above problem.

Thanx Ronald
