When the application (NSS) does not use WaitForSlotEvent and just
opportunistically tries to detect card and reader removals with
C_GetSlotInfo() and C_GetSessionInfo(), we might get errors in
various plcaes, in the sc_lock() function, when we try to transfer
other messages or when we ask for the reader status.
This is generally too late to call any disconnect functions because no
PC/SC handles are valid anymore. The reader state from PCSC
is searched by name so we can be pretty sure it is very similar
reader (with same name as the old one) and I hope we can reuse the
reader structure and just call the pcsc_connect() on that as we do
with invalid handles.
Otherwise we detect this issue in the refresh_attributes() (called
from C_GetSlotInfo()), where we can report the slot change in the
expected manner.
Fixes#1822
The error was
fuzz_pkcs15_reader.c: In function ‘fuzz_get_chunk’:
fuzz_pkcs15_reader.c:66:19: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
66 | *chunk_size = (uint16_t) data->Data;

cc1: all warnings being treated as errors
The negative integers were parsed uterly wrong, resulting in undefined
shift overflows as reported by oss-fuzz.
The current implementation takes negated values (properly masked) and
calculates two's complement in the end, which results in correct values
and correct data handling.

* pkcs11-register: Fixed detection of already registered OpenSC
Anny configuration of onepin-opensc-pkcs11.so and opensc-pkcs11.so
should be enough to skip registering the default module again.
* Use onepin module for generic NSS DB
fixes https://github.com/OpenSC/OpenSC/issues/1818
May have the disadvantage that some other programs that use NSS don't
see the signature keys. However, we currently only know for sure that
Chromium is using the generic NSS DB.
The corresponding GET DATA command only returns the serial,
nothing else.
Tested with CardOS 5.0 and 5.3 cards. The serial number
is the same as shown with other tools
Changed four places where "<" should be "<=" so Le will be set correctly
Previous for 65K (extended) or 256 (short) Le is left set to 0.
This then caused Le to be to be not added to APDU as Le==0
Code later converts actual Le in APDU to be set to 0 to mean 256 or 65K.
SC_APDU_CASE_*_EXT are changed to SC_APDU_CASE_* so sc_detect_apdu_cse
to set the cse based on card capabilities as well as data chaining.
This commit is not well tested and neds review.

buf_len is a CK_ULONG (unsigned long). But if the attribute is sensitive
or is not extractable or is invalid for the object then the library set
the buffer length value to (CK_LONG)-1.
It is more friendly to see "-1" instead of "18446744073709551615" (on
64-bits CPU)
opensc-tool: for options --version, --list-readers, -D, etc. we do not
need to connect card/reader. This removes unnecessary error messages
if card is not present in card reader or if reader is not available.
util.c: use symbolic error codes, pass error codes to caller without change.
CID 344928 (#1 of 1): Sizeof not portable (SIZEOF_MISMATCH)
suspicious_sizeof: Passing argument object_handles of type CK_OBJECT_HANDLE_PTR and argument objects_length * 8UL /* sizeof (CK_OBJECT_HANDLE_PTR) */ to function realloc is suspicious. In this case, sizeof (CK_OBJECT_HANDLE_PTR) is equal to sizeof (CK_OBJECT_HANDLE), but this is not a portable assumption.
CID undefined (#1 of 1): Unchecked return value (CHECKED_RETURN)
10. check_return: Calling RSA_set0_key without checking return value (as is done elsewhere 7 out of 8 times).
* The fail_msg() in cmocka has a way not to fail, which confuses coverity. Adding explicit retunr/exit should address this issue
* Reformat some code in p11test
Option -r is used in other opensc tools to specify card reader. pkcs15-tool
uses -r to specify cerfificate. This fix intorduces warning message if -r
is used, and for future versions of pkcs15-tool -r is used to specify
reader.
sc-ossl-compat.h will check if OpenSSL has been built with or without some
deprecated defines. OpenSSL will provide defines for some of these if
built to still support depreacted routines but not if built with
"no-depracted". .
This commit will define some of the needed defines if ther are not
defined by OpenSSL. Thus if a distro builds OpenSSL with "no-depracted"
it can still be used.

When card supports SC_ALGORITHM_RSA_PAD_PKCS1 but not SC_ALGORITHM_RSA_HASH_NONE, then the DigestInfo need to be removed.
Current check make requires the card to not support both SC_ALGORITHM_RSA_PAD_PKCS1 and SC_ALGORITHM_RSA_HASH_NONE to have the removal done.
when importing a private key onto a pkcs15 card, if the card does not support
extended APDUs, we need to use chaining to store keys longer than 255 bytes.
While for RSA keys, this check was included, it was missing for EC keys.
This patch adds the SC_APDU_FLAGS_CHAINING flag to apdu.flags if data length is
greater than 255 and the card caps does not include SC_CARD_CAP_APDU_EXT.
Fixes#1747
The check condition is obviously wrong. It should check for EQUAL. The original bitwise check caused any other language to turn into DE because as long as a bit is filtered, it will hit.
Fixes regression from commit 3688dfe which did not consider that
the zero prefixing tests were too generic and matched EC keys too.
This simplifies the code even further and avoids data copying
when possible. Proper test is now included to do data value prefixing
only for the RSA keys it is needed.
Closes#1701.
At the point when gemsafe_match_card is called, the card type is already known,
either because of a previous match at card.c, or because it is forced at opensc.conf.
With this redundant match it's not possible to force selection on opensc.conf.
