spy segfaulted if CKU_CONTEXT_SPECIFIC was used,
pkcs11-session was reseting the userType before calling
framework. Framework will now see CKU_CONTEXT_SPECIFIC
and use slot->login_user to determine which PIN was used
to create the original session, and will send the PIN
to the card. It does not treats CKU_CONTEXT_SPECIFIC
as a full login, only a reassertion of the PIN.

sc_pkcs15_cert now has pointer to sc_pkcs15_pubkey, allowing it to
be removed and used separatly.
sc_pkcs15_pubkey now has pointer to sc_algorithm_id to faclitate
addition of other key algorithms and their parameters.
Various code changes to free these structures and references
to the structures have been changed.

Assuming the driver has correctly set max_tries to 1 then PKCS#11 is very clear about it:

Support for importing cleartext keys is left untouched, but all transparent key generation by either opensc-pkcs11.so or pkcs15-init is removed, to make the operation with cleartext keys visible to the user and his explicit wish.
OpenSC is a PKCS#11 library for accessing keys protected by a smart card. Key material in software is not protected by smart cards and can leave a false sense of security to the user.

From http://en.wikipedia.org/wiki/Malloc#Casting_and_type_safety
" Casting and type safety
malloc returns a void pointer (void *), which indicates that it is a
pointer to a region of unknown data type. One may "cast" (see type
conversion) this pointer to a specific type, as in
int *ptr = (int*)malloc(10 * sizeof (int));
When using C, this is considered bad practice; it is redundant under the
C standard. Moreover, putting in a cast may mask failure to include the
header stdlib.h, in which the prototype for malloc is found. In the
absence of a prototype for malloc, the C compiler will assume that
malloc returns an int, and will issue a warning in a context such as the
above, provided the error is not masked by a cast. On certain
architectures and data models (such as LP64 on 64 bit systems, where
long and pointers are 64 bit and int is 32 bit), this error can actually
result in undefined behavior, as the implicitly declared malloc returns
a 32 bit value whereas the actually defined function returns a 64 bit
value. Depending on calling conventions and memory layout, this may
result in stack smashing.
The returned pointer need not be explicitly cast to a more specific
pointer type, since ANSI C defines an implicit conversion between the
void pointer type and other pointers to objects. An explicit cast of
malloc's return value is sometimes performed because malloc originally
returned a char *, but this cast is unnecessary in standard C
code.[4][5] Omitting the cast, however, creates an incompatibility with
C++, which does require it.
The lack of a specific pointer type returned from malloc is type-unsafe
behaviour: malloc allocates based on byte count but not on type. This
distinguishes it from the C++ new operator that returns a pointer whose
type relies on the operand. (see C Type Safety). "

In fact, the middleware of the manufacturer of the gemalto (axalto, gemplus) cards
reports the CKA_ID of CA certificates as '0'.
But it's not true for the others middlewares (Oberthur), NSS (afais) and PKCS#11 standard.

- slots, sessions and objects are kept as lists.
- change the way slots, cards and readers are managed.
- re-implement C_WaitForSlotEvent(/C_Finalize) as written in PCKS#11 v2.20, canceling pending blocking calls.
- implement a "virtual hotplug slot" with a floating slot id to keep NSS working with C_WaitForSlotEvent with a new reader.
NSS does not call C_GetSlotList(NULL) to re-fetch the list of available slots if C_WaitForSlotEvent returns an event in an already known slot ID.
By changing the ID of a slot whenever a reader attached NSS/Firefox can be tricked into recognizing new readers when waiting for events with C_WaitForSlotEvent.
- change (possibly break something) sc_to_cryptoki_error() to not have side-effects
- Implement CKU_CONTEXT_SPECIFIC in C_Login to implement CKA_ALWAYS_AUTHENTICATE (keys with user consent)

One of the three unblock methods can be activated from the 'opensc-pkcs11' section of opensc.conf:
- C_SetPin() in the unlogged sesssion;
- C_SetPin() in the CKU_SPECIFIC_CONTEXT session;
- C_InitPin() in CKU_SO session (inspired by Pierre Ossman).
-- This last one works, for a while, only for the pkcs15 cards without SOPIN auth object.
For the pkcs15 cards with SOPIN, this method will be useful for the cards
that do not have then modes '00' and '01' of ISO command 'RESET RETRY COUNTER'.
Test commands:
# pkcs11-tool --module ./opensc-pkcs11.so --slot 0 --unlock-pin --puk "123456" --new-pin "9999"
# pkcs11-tool --module ./opensc-pkcs11.so --slot 0 --unlock-pin -l --login-type context-specific --puk "123456" --new-pin "9999"
