On a Solaris 10 sparc machine, using pcsc and opensc both from
svn, there appears to be a mismatch of handing the length
field within the message for using a pin pad reader.
pcscd trace shows:
00000126 ../../src/src/ifdhandler.c:1307:IFDHControl() ControlCode: 0x42330006,
usb:076b/3821:libusb:/dev/usb:76b.
3821/0 (lun: 0)
00000068 Control TxBuffer: 1E 1E 02 08 00 04 08 02 FF 00 00 00 00 00 00 00 00
00 0D 00 20 00 80 08 FF FF FF FF FF
FF FF FF
00000636 ../../src/src/commands.c:312:SecurePINVerify() Wrong lengths:
218103827 32
00000055 Control RxBuffer:
00000049 ../../src/src/ifdwrapper.c:644:IFDControl() Card not transacted: 614
This comes down to: 218103827 = 0x0D000013
as the test in ccid commands.c is testing:
if (dw2i(TxBuffer, 15) + 19 != TxLength)
which if it was stored as 0D 00 00 00, dw2i would have converted it to
13+19=32, and the length would have been correct.
OpenSC internal-winscard.h appears to be where the problem is:
#define HOST_TO_CCID_16(x) (x)
#define HOST_TO_CCID_32(x) (x)
Where as PCSC/reader.h has:
#define HOST_TO_CCID_16(x) ((((x) >> 8) & 0xFF) + ((x & 0xFF) << 8))
#define HOST_TO_CCID_32(x) ((((x) >> 24) & 0xFF) + (((x) >> 8) & 0xFF00) + ((x
& 0xFF00) << 8) + (((x) & 0xFF) <<
24))
and PCSC has in "configure.in" tests for bigendian using:
# HOST_TO_CCID
if test "x$ac_cv_c_bigendian" = "xyes"; then
AC_SUBST(host_to_ccid_16, ['((((x) >> 8) & 0xFF) + ((x & 0xFF) << 8))'])
AC_SUBST(host_to_ccid_32, ['((((x) >> 24) & 0xFF) + (((x) >> 8) & 0xFF00
) + ((x & 0xFF00) << 8) + (((x
) & 0xFF) << 24))'])
AC_MSG_RESULT([plateform endianess : big endian])
else
AC_SUBST(host_to_ccid_16, ['(x)'])
AC_SUBST(host_to_ccid_32, ['(x)'])
AC_MSG_RESULT([plateform endianess : little endian])
fi
It looks like OpenSC need to test for bigendian.
(On the Muscle list there is a discussion of size of DWORD, and since the
SecurePINVerify is using dw2i() assuming 32 bit number,
this might also cause an error on a 64 bit machine trying to use a
pin pad reader.)
