Package: libpcsclite-dev
Severity: normal
Tags: patch
Hi,
I saw Kuro-box Pro (arm arch) users claims that when they use program
to decode B25 data that build with libpcsclite-dev, it occurs
"winscard_svc.c:565:MSGCheckHandleAssociation() Client failed to authenticate"
error.
With PCSC-Lite, "transmit_struct_extended" structure is defined as below
----------------------------------------------------------------------------
struct transmit_struct_extended
{
int32_t hCard;
uint32_t pioSendPciProtocol;
uint32_t pioSendPciLength;
uint32_t cbSendLength;
uint32_t pioRecvPciProtocol;
uint32_t pioRecvPciLength;
uint32_t pcbRecvLength;
uint32_t rv;
uint64_t size;
uint8_t data[1];
};
typedef struct transmit_struct_extended transmit_struct_extended;
----------------------------------------------------------------------------
and in src/winscard_clnt.c, SCardTransmit() function is
----------------------------------------------------------------------------
2894 unsigned char buffer[sizeof(sharedSegmentMsg) + MAX_BUFFER_SIZE_EXTENDED];
2895 transmit_struct_extended *scTransmitStructExtended =
(transmit_struct_extended *)buffer;
2896 sharedSegmentMsg *pmsgStruct = (psharedSegmentMsg)buffer;
2897
2898 scTransmitStructExtended->hCard = hCard;
2899 scTransmitStructExtended->cbSendLength = cbSendLength;
----------------------------------------------------------------------------
hCard in line 2898 will be changed when 2899 called, they say.
And some of them pointed out what they need is to set "CFLAGS =
-fno-strict-aliasing"
for workaround.
I don't have any (configurable ;) arm box, so I'm sure attached patch works or
not.
But, anyway, could you check it please?
