G'day,

A while ago I had made a patch dealing with data objects where the
CKA_VALUE was being stored in the attribute file under certain
circumstances (which usually causes the attribute file to run out of
space). I do not know if this will fix your problem but it might be
worth a try. See attached patch for p11_object.c
I applied the patch, but I still can view only one data object,
regardless of how many data objects I create.
I also used muscleTool to verify this.
On an empty card, there are no objects present:
muscle [MuscleCard Applet] > list
Object ID Object Size READ WRITE DELETE
----------------- ----------- ------ ------ ------
ERR: ListObjects Failed (0x9C12 End of sequence)
After I create one data object on the card, muscleTool shows the following:
muscle [MuscleCard Applet] > list
Object ID Object Size READ WRITE DELETE
----------------- ----------- ------ ------ ------
o0 512 ALWAYS PIN #1 PIN #1
O0 3 PIN #1 PIN #1 PIN #1
The object with ID "O0" represents the 3-byte value of the PKCS#11 data
object, the object with ID "o0" presumably represents the other PKCS#11
attributes.
I can view the data object using PKCS#11 commands, but when I delete
file with object ID "o0", then I cannot view the data object using
PKCS#11 commands.
Next, if I create three PKCS#11 data objects, then use muscleTool to
list the contents of the card, I get the following:
muscle [MuscleCard Applet] > list
Object ID Object Size READ WRITE DELETE
----------------- ----------- ------ ------ ------
O0 3 PIN #1 PIN #1 PIN #1
o0 512 ALWAYS PIN #1 PIN #1
This is the same object list as creating one PKCS#11 data object. Using
PKCS#11 if I create three objects and find objects in the same session,
then the find returns the three newly-created objects. If I pause
between creating the data objects and viewing them in the one session,
then muscleTool still shows the two objects listed above. So I assume
that some form of caching is occuring in libmusclepkcs11 here?
