empty response -> crash on empty sw1 #18

Closed tshirtman closed 8 years ago

tshirtman commented 8 years ago

looks a lot like https://github.com/LudovicRousseau/pyscard-contrib/issues/2

trying any example with transmit (here http://pyscard.sourceforge.net/pyscard-framework.html#selecting-the-df-telecom-of-a-card), with any tag, i get:

insert a card (SIM card if possible) within 10s

IndexError: list index out of range

when i get down to it with pudb, response is just [] in there, so of course it's out of range. First tried with python-pysdcard from ubuntu repository, then i built/installed from source (this repository). I'm having a look into scard.i, and SCardTransmit, but i have no experience with swig, so i'm not positive i'll find the cause on my own, so any idea welcome :). If i start gscriptor and run a script like FFCA000000, i do get an answer, so i guess pcscd is working correctly.

result of pcsc_scan in case it helps

What happens with gscriptor if you send the APDU "A0 A4 00 00 02 7F 10"?

tshirtman commented 8 years ago 
Sending: A0 A4 00 00 02 7F 10 
Received: 
wrong SW size for: 

Script was executed without error...

not much apparently…

Thanks for fast answer :)

edit: this made me understand (quite new to rfid, sorry) that what i want mainly, getting tag ID was simpler than i though, i was sending SELECT + FFCA000000 for that, when i only needed the latter part, and in this case, answer is immediate, so for now i'm settled, but if think there is a real bug to solve in pyscard for the DF_TELECOM (if it should work with any tag/reader), i can help debugging this further, it might be useful in the future.

LudovicRousseau commented 8 years ago

Can you generate pcscd logs as described in https://pcsclite.alioth.debian.org/ccid.html#support and send the problematic APDU A0 A4 00 00 02 7F 10 using gscriptor ?

tshirtman commented 8 years ago

I've read a bit more about DF_TELECOM, which i was only trying because it was the example, it seems only about SIM cards, maybe it's normal that i don't get an answer for it with my simple rfid/nfc tags?

LudovicRousseau commented 8 years ago

Please attach a complete pcscd log.

tshirtman commented 8 years ago

Sorry, i though keeping only the communication part would be more useful

LudovicRousseau commented 8 years ago

The reader firmware is bogus. It returns 80 00 00 00 00 00 0F 00 FE 00 bStatus = 0x00 indicating No Error bError = 0xFE indicating ICC_MUTE, CCID timed out while talking to the ICC

The reader should report an error in bStatus so that the driver knows something failed and returned an error so that the upper layers, in this case pyscard, do not try to parse the empty result.

LudovicRousseau commented 8 years ago

Can you follow https://pcsclite.alioth.debian.org/ccid.html#CCID_compliant please?

Your reader is already in the "unsupported" list but I want to know what firmware version you are using https://pcsclite.alioth.debian.org/ccid/unsupported.html#0x072F0x2200

tshirtman commented 8 years ago

Sure, here it is, thanks for looking into it and explaining, i've been told this reader was quite common, so though it would have good support, but maybe it's limited by a bad firmware, support is good enough for what i want for now anyway :), i guess i should have started with the support list.

You are using a "recent" firmware bcdDevice: 2.14. I added a note to https://pcsclite.alioth.debian.org/ccid/unsupported.html#0x072F0x2200 It is not a bug in pyscard. Thanks for your help.
