Since commit dba0f56 the tokenPresent parameter is ignored in case the
slot has been already seen.
This breaks the API expectations as we may return a slot that has no
token inserted.
So, only consider the SC_PKCS11_SLOT_FLAG_SEEN if tokenPresent is false
While trying to setup an OpenSC context, the global_locking
and detect cards, it is possible that multiple threads may
call C_Initialize. The current code tries to prevent this using
"if (context == NULL)" but this is not a mutex, and
multiple threads may endup overwrite contexts and global locking and
cause additional problems, with pcsc and segfault.
FireFox appears to do this see #2032
The PR adds a mutex or Critical section to make sure only one
thread creates the context sets the global_locking and does
the initial detect cards, etc.
This allows the global_lock (if requested) to be setup
which is then used for other calls.
All but the first call to C_Initialize will return with CKR_OK,
others will return CKR_CRYPTOKI_ALREADY_INITIALIZED.

Changes to be committed:
modified: src/pkcs11/pkcs11-global.c
before 14e396273 sc_wait_for_event() only notified in case of a new
reader, but didn't add it to the internal list of readers. That's why
PKCS#11 needed to bail out early in this case (and the application had
to call C_WaitForSlotEvent a second time to actually get the related
slot). Since sc_wait_for_event() can now handle insertion correctly, we
can now immediately check (and reset) the events on the slots.
- when listing the slots, we don't have a hotplug slot anymore with
slot->reader == NULL. Instead, we're now using this state for any left
over slots when a reader is removed. So we don't need to include this in
the slot list
- when listing the slots, we need to remember which slots the
application has seen already, to not shrink the list of slots (which is
allowed in PKCS#11 v2.2, but NSS can't handle this)
Since "Add GCC format checking attributes to log functions" commit GCC
warns us about problems with format strings and their arguments provided
to OpenSC message logging functions.
This commit fixes all cases where GCC warned about incorrect format on
64-bit Linux, 32-bit and 64-bit mingw builds (with SM and OpenSSL enabled).
Well, almost all since on mingw GCC does not recognize "ll" size specifier
(present at least since Visual Studio 2005, also in mingw own CRT) so these
(few) warnings about it remain.
In most cases format size specifier for size_t type was missing (usually
size was left at default int level, with is different on 64-bit x86).
Some formats had too few / too many arguments.
In some cases pointers were printed as integers.
Some long variables were missing "l" prefix (especially with regard to %x
format).

... as required by PKCS#11 2.30, if the application doesn't call
`C_GetSlotList` with `NULL`.
Fixes ghost tokens in Firefox when detaching a reader that contained a
card.
Fixes https://github.com/OpenSC/OpenSC/issues/629
* Add configure-time dependency on pcsclite (required version from comments in reader-pcsc.c)
* The functionality is already supported in PCSC-Lite
* For older PCSC-Lite versions still return CKR_FUNCTION_NOT_SUPPORTED
# closes#899
This is name change only fix.
The variable name "card" was being used to refer to a struct sc_card or a struct sc_pkcs11_card
in some files including sc_pkcs11.h. In other files the variable name "p11card" is used for struct sc_pkcs11_card.
This creates hard to read code, such as: slot->card->card.
All definitations of sc_pkcs11_card *card now use p11card as the variable name.
Fix#471
to prepare future enhancements and in the sake of uniformity
in 'struct sc_pkcs11_framework_ops'
the 'struct sc_pkcs11_card' argument of 'init_token' handler is changed for 'struct sc_pkcs11_slot'
coding style issues
The list of slots returned by C_GetSlotList() contains:
- if present, virtual hotplug slot;
- any slot with token;
- without token(s), one empty slot per reader;
