[Tpm4java-users] tpm4java: count not init dll code: -2

[Markus <ax...@go...>]

Hi!

Is tpm4java limited to tpm emulators or does it also work with 'real' tpms?

This is my tpm:

Trusted Platform Module:
TCG Spec. Version = 1.2
Infineon Technologies AG
SLB 9635 TT 1.2 (41313100)

and this is the exception I get while initializing the tss:

java.lang.RuntimeException: count not init dll code: -2
	at de.datenzone.tpm4java.TddlJniDeviceDriver.<init>(TddlJniDeviceDriver.java:74)
	at de.datenzone.tpm4java.TssFactory.getLowlevel(TssFactory.java:165)
	at de.datenzone.tpm4java.TssFactory.getHighLevel(TssFactory.java:183)

(there is no TPMDDL.dll so I had to create a copy of IFXTPM.dll which
is the actual device driver).

Please help!

This works with real TPMs too, it is not limited. But we did not test it
with your one I think.

I don't know exactly what is going wrong here, I will have to step to
the code. Can you install an C-Compiler to compile some simple tests?

Erik:

thank you for your quick reply!

I'll be glad to do some testing, C code is just fine!

Please don't gun down my tpm :-)

OK, here is the code from tpm4java which seems to cause this problem:

        opentpm =3D (MyTddli_Open) GetProcAddress(dll, "Tddli_Open");
        if (opentpm =3D=3D NULL) {
		(*env)->ReleaseByteArrayElements(env, dllname, realname, 0);
		FreeLibrary(dll);
                return -2;
        }

So, could you send me your dll please or check if there is really a
function called "Tddli_Open" in that file?

Erik:

here's the function list:

TDDL_Cancel	0x10002740	0x00002740	1
(0x1)	IFXTPM.dll	C:\WINDOWS\system32\IFXTPM.dll
TDDL_Close	0x10002440	0x00002440	2
(0x2)	IFXTPM.dll	C:\WINDOWS\system32\IFXTPM.dll
TDDL_GetCapability	0x100028e0	0x000028e0	3
(0x3)	IFXTPM.dll	C:\WINDOWS\system32\IFXTPM.dll
TDDL_GetStatus	0x100025a0	0x000025a0	4
(0x4)	IFXTPM.dll	C:\WINDOWS\system32\IFXTPM.dll
TDDL_Open	0x100022f0	0x000022f0	5
(0x5)	IFXTPM.dll	C:\WINDOWS\system32\IFXTPM.dll
TDDL_SetCapability	0x10002d60	0x00002d60	6

TDDL_TransmitData	0x10003090	0x00003090	7
(0x7)	IFXTPM.dll	C:\WINDOWS\system32\IFXTPM.dll

I guess the infineon driver is not 100% TSS 1.2 compliant. Could you
do a workaround that accepts both sets of function names?

Sorry, I can't. My Windows system crashed some days ago, and now I
cannot compile any windows code.

But you can just use the latest release, rename the function names in
javaddl.c and recompile it. Then you can use it with your tpm.

I used visual studio .net 2005 for that, that worked fine.
