Re: [Xense-devel] vtpm_managerd problem

[Burak OÐUZ <burakoguzs@xxxxxxxxx>]

I have cleared the TPM and as you said vtpm_managerd tried to take the ownership of the IFX TPM. After clearing once, I tried 3 times and in all of them it gives different errors.

In the first time :

dungeon burak # vtpm_managerd
INFO[VTPM]: Starting VTPM.
INFO[TCS]: Constructing new TCS:
INFO[TCS]: Calling TCS_OpenContext:
INFO[VTSP]: OIAP.
ERROR[VTPM]: Failed to load service data with error = TPM_IOERROR
INFO[VTPM]: Failed to read manager file. Assuming first time initialization.
INFO[VTSP]: Reading Public EK.
INFO[VTSP]: Taking Ownership of TPM.
INFO[VTSP]: Disabling Pubek Read.
ERROR[TCS]: TCSP_DisablePubekRead Failed with return code TPM_BAD_ORDINAL
ERROR in VTSP_DisablePubekRead at vtsp.c:428 code: TPM_BAD_ORDINAL.
ERROR in VTPM_Create_Manager at vtpm_manager.c:106 code: TPM_BAD_ORDINAL.

In the second time :

It had created binding keys and while loading the keys into the tpm it gave bad ordinal error again.

INFO[VTPM]: Saved VTPM Manager state (status = 0, dmis = -1)
INFO[VTSP]: Loading Key into TPM.
ERROR[TCS]: TCSP_LoadKeyByBlob Failed with return code TPM_BAD_ORDINAL
ERROR in VTSP_LoadKey at vtsp.c:634 code: TPM_BAD_ORDINAL.
ERROR in VTPM_Init_Manager at vtpm_manager.c:243 code: TPM_BAD_ORDINAL.
ERROR[VTPM]: Closing vtpmd due to error during startup.


And in the third time :

dungeon burak # vtpm_managerd
INFO[VTPM]: Starting VTPM.
INFO[TCS]: Constructing new TCS:
INFO[TCS]: Calling TCS_OpenContext:
INFO[VTSP]: OIAP.
INFO[VTSP]: Loading Key into TPM.
ERROR[TCS]: TCSP_LoadKeyByBlob Failed with return code TPM_BAD_ORDINAL
ERROR in VTSP_LoadKey at vtsp.c:634 code: TPM_BAD_ORDINAL.
ERROR in VTPM_LoadManagerData at securestorage.c:453 code: TPM_BAD_ORDINAL.
ERROR[VTPM]: Failed to load service data with error = TPM_BAD_ORDINAL

Simply there is a situation with ordinals sent to TPM. In trousers there exists a patch for infineon tpms for these issues. Is this a similar sitution like this?

Thanks again...

Best regards..

This is correct: The vtpm manager tries to use the TPM, but can not take ownership because the TPM was in use before.
If you clear your TPM (should be a BIOS option, perhaps you need to press a special key on boot or set some jumper), and then start the vtpm manager again, you should be fine.

HTH,
Martin
