nfc-mfclassic doesn't work when used with mifare 4k emulated #98

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 

I have the following tools:
- Feig Elettronics M02 reader e software tool.
- Reader ACR122U102 - PN532,
- Nokia 6212 with Mifare 4k,
- MIFARE 4k (emulated)
- Another Mifare 1k.

If I use the Feig and proprietary software for windows, I get the following 
dump:

Nokia 6212 phone - sector 0:

work well.

If  use nfc-mfclassic, micmd  or another tools with libnfc and PN532:

FF FF FF FF FF FF FF 07 80 69 00 00 00 00 00 00
.... ok.

libnfc correctly read the Mifare 1k,  but the 4k filled with FF and the UID. 
This seems very strange .... libnfc Bug?

Hello,
Thanks for report.

Could you try with current libnfc's trunk version ?

On which OS do you use libnfc ?

Thanks for the reply.

I used micmd in Windows XP.
Even with Ubuntu 10.04, libnfc 1.3.4 have the same problem.
Now i'm using Slackware 13 with libusb 1.0.0 because 1.0.8 have problems with 
stability with the reader.

However, try libnfc svn version in Slackware 13:

This issue was updated by revision r526.

This should fix the problem: because the response was not the expected length, 
the actual card data was not copied to the buffer, so it was always the same 16 
uninitialized bytes that where returned for any block.

Meh. In this case, I can't reproduce the issue.

Please ensure:
  - You are using the code from trunk (e.g. svn info);
  - You are not running old versions of the examples (the best to ensure you run examples with the appropriate library is to run them using the wrappers in the examples directory (i.e. ./examples/nfc-list and so on).

You may also try with a non-emulated target (just in case)

Can you please add --enable-debug=yes to your ./configure flags and retry?

Thanks!

Thanks for the debug trace!  If I compare yours and mine I see something that 
looks like extra bytes in your case (e.g. I get: "RX: d5  41  00  90  00" when 
you have "RX: d5  41  00  6e  00  90  00". 

I'll hopefully come back to you soon with a fix / questions.

Thank you very much and good work.
I remind you that sometimes I even stability problems. I do not know if there 
are traces of this. I will try in coming days to use Ubuntu because worked 
better.

I did a test with key b.

Hum, no more luck but that does not surprise me: if authentication with Key A 
gives strange results, I feel better knowing that authentication with Key B 
also does the same :-)

A quick way to see if some data is actually read is to check the debug output: 
in your case, no RX lines contains data, while you should have looooooong RX 
lines such as:

 TX: ff  00  00  00  05  d4  40  01  30  07  
 RX: d5  41  00  00  00  00  00  00  00  ff  07  80  69  ff  ff  ff  ff  ff  ff  90  00  
 TX: ff  00  00  00  05  d4  40  01  30  06  
 RX: d5  41  00  00  00  00  00  00  00  00  00  00  00  00  00  00  00  00  00  90  00  
 TX: ff  00  00  00  05  d4  40  01  30  05  
 RX: d5  41  00  00  00  00  00  00  00  00  00  00  00  00  00  00  00  00  00  90  00  

In your case it's more like:

 TX: ff  00  00  00  05  d4  40  01  30  07  
 RX: d5  41  00  6f  00  90  00  
 TX: ff  00  00  00  05  d4  40  01  30  06  
 RX: d5  41  00  6f  00  90  00  
 TX: ff  00  00  00  05  d4  40  01  30  05  
 RX: d5  41  00  6f  00  90  00  

... I guess there is some error checking missing in the examples ;-)

Let's dig into your frames:

0xd541 is a reply to the 0xd540 command.  The next byte 0x00 is supposed to be 
the error status (0 = no error) and the rest should be the data returned by the 
card, according to the PN532 documentation.  Here it starts to be tricky, for a 
reply to a Mifare Classic "read" command:
  - The libfreefare comments says "No result.  The MIFARE tag just ACKed." and I was pretty sure there was no additional data at all (since I wrote that comment);
  - I have 0x9000 (meh … however, at the libfreefare's level I don't see this extra data. I just see it at the libnfc level. But I can't recall how these bytes are stripped... I'll have to look at this I guess since it does not work as I think it does);
  - You have 0x6e009000 and 0x6f009000 (which is even more weird).

Let's make it even a bit more funny, (with no search, so maybe it is 100 % 
irrelevant, but it's so unlikely I can't think it is a coincidence):
  - 0x9000 correspond to the status-byes in ISO/IEC 7816-4 for "Normal processing";
  - 0x6e00 is a "Class not supported" error in the same document, same table;
  - 0x6f00 is a "No precise diagnosis" error always in the same status-bytes table.

… Looks like an error frame (0 bytes of data followed by the error status 
"0x6x00") is transmitted "as-it" successfully (2 bytes of data "0x6x00" 
followed by the success status-code "0x9000")...

You said you have a passive 1k target? Can you please try to dump it and attach 
a trace like you did previously?  I would like to be sure about the extra bytes 
being send by the telephone emulating a NFC target (and not added by the NFC 
initiator) and that everything is fine when you use passive targets.

It might also be interesting to give the libfreefare's examples a try: they 
might fail "earlier" with more relevant error messages (not that my 
brain-embedded hexadecimal ADPU decoder is bad, but it might miss things).

And finally, have you ever got the examples working with the telephone 
emulating a target ?

Thanks!

Hey!

Looks like the uploaded debug trace is not the good file, but BTW, the dump 
looks-like much more what we expect!

So, I suspect a weirdness in the communication with the telephone (and not the 
device)…  Do you have some "advanced documentation" that way have useful 
information about "how emulation works" ?  I don't really know what you can 
look for exactly, but maybe you can "switch NFC communication modes" on the 
telephone, or maybe it is required to put the PN532 in a particular 
configuration… No real idea, mobile-phones or somewhat cursed devices as far 
as I can tell (I don't own one).

Thanks, and good luck!

1) I am sure that the phone is turned on. ;-)
   (Access to the secure element is to set free)
2) I write on the console  > nfc-mfclassic  r a  ....
3) I position my hand and phone near the reader (1 cm).
4) Press ENTER on the keyboard.
5) I stand while reading.
6) After the reading, take away the phone.
7) I read the result.

I attach a screenshot of the Feig reader and its software manager. The reading 
is correct.
