Hello Douglas and Anthony,
sorry for late reply and cool, thanks you for helping me with gdb :-).
Thanks to you help I was able to run with my loaded library in debug mode.
Anyway, the crash (in the debug mode) looks as follows:
Program received signal SIGSEGV, Segmentation fault.
0xd810b787 in ?? ()
where 0xd810b787 is p11->C_Initialize (checked with printf("p11 = 0x%0x,
p11->C_Initialize = 0x%0x\n", p11, p11->C_Initialize);)
>OK, but is 0x5810b6fa in your module?
This I am not completely sure about. But I don't really know how can I find
out if this is in my module or not.
I suspect that there is C_Initialize defined also somewhere else and the
pkcs11-tool picks it from somewhere else and not from my library.
>I will ask again, does your module define the C_GetFunctionList, and does
it
>return a valid function list?
Yes it has - in the upper layer of the library I defined it as
CK_DEFINE_FUNCTION(CK_RV, C_GetFunctionList)
(
CK_FUNCTION_LIST_PTR_PTR ppFunctionList // receives pointer to function
list
)
{
try
{
API_ENTRY();
API_PARAM_PTR_EX("ppFunctionList", ppFunctionList);
if (ppFunctionList == NULL)
API_EXIT(CKR_ARGUMENTS_BAD);
*ppFunctionList = &functionList;
API_EXIT(CKR_OK);
}
catch(...)
{
TRACE_ERROR("Catching top-level exception", "");
API_EXIT(CKR_FUNCTION_FAILED);
}
}
And it should return a valid function list. In fact I have my own small
test tool that uses dlopen(libname, RTLD_NOW) to open the library and
GetFuncList = (C_GetFunctionListPtr)dlsym(lib, "C_GetFunctionList") to get
the correct address of the functions.
I believe this is the same thing as done with pkcs11-tool, but somehow it
works in my small test tool, I can do C_Initialize and other pkcs11
functions and in pkcs11-tool it crashes.
I have Ubuntu11.10, 32bit and the OpenSC version is very recent -
opensc 0.12.1-1ubuntu1
I took it from here: http://apt.gooze.eu/ubuntu/dists/oneiric/
Cheers,
Anna
