We can't check for `tag == SC_ASN1_TAG_EOC` directly, because this
would also be true for a tag of 0x80 (with `class ==
SC_ASN1_CLASS_CONSTRUCTED`). So what we do is we check for the output
buffer to be NULL!

for 3.5 everything is fine.
In order to satisfy some concerns over the use of <card>_match_card

overhead of repeating some card commands.

Some CAC card return '6A80` Incorrect parameters in APDU when trying to
read the Discovery object. If it fails other then not found, then we can
not use the Discovery object to test for the active AID.
The test is done in piv_match_card just after doing a SELECT AID for the PIV.
and set CI_DISCOVERY_USELESS if needed. piv_card_reader_lock_obtained will
then not use the Discovery object.
Some older PIV cards, prior to the introduction of the PIV
Discovery and History objects, may get errors trying to read them.
Ignore these errors too.

Framework-pkcs15.c will now set pin_info->auth_method to SC_AC_CONTEXT_SPECIFIC
iso7816.c iso7816_build_pin_apdu treats this the same as SC_AC_CHV
card-piv.c piv_pin_cmd sets priv->xcontext_specific=1 and calls sc_lock before
the verify command. If the verify fails sc_unlock is called.
Later after the next card command returns, if priv->context_specific==1 piv_check_sw
will call sc_unlock as the application may not have requested the crypto but
some other command.
Some additional calls to sc_lock and sc_unlock have been added to make sure
PIV internal command sequences including the crypto command ('87') and any get
responses are always protected by a lock.
This guarantees the card is locked for verify and the next command
which should be the crypto operation. The PIV card also inforces this restriction
on the card.
This is based on suggestions in:

Many OpenSC drivers try and detect during match if the card supports
their AID by doing a SELECT FILE for the AID.
But this can cause problems with cards such as Yubico that do not ignore
SELECT AID commands for applications they do not support. Other cards may
have the same problems. Selecting the wrong AID can also lose the security
state.
The card-piv.c will now uses the GET DATA to read the PIV Discovery Object '7E'
which is a ISO standard template that will contain the AID of the currently
active application. The driver will then double check that the template is
for the PIV application.
If the template contains the PIV AID, then no SELECT AID is done.
PIV standards say there can only be one PIV application on a card.
PIV standards also say PIV must be the the default application,
but Yubico does not follow this.
The command fails only then will a SELECT AID be done.
Thus this can avoid the Yubico problem.
This logic is used in both "match" and in the piv_card_reader_lock_obtained
routine.
Additional logic was in piv_card_reader_lock_obtained was added to handle
when the card reset was received by some other program. Multiple programs
may be trying to use the PIV application on the card, and thus multiple
programs will all receive that the card was reset. The first program to receive
the card was reset will do all of the above logic, and may leave the card in
a state will cause other programs to not have to do much at all.
The intent of all of this is to avoid sending extra commands to the card
including SELECT AID that could change the card state when not needed.

Use names that are specific to EAC, not the German ID card (nPA),
because Protocol and Commands are defined by BSI TR-03110 and ICAO.
Functions that are nPA specific are moved to card-npa.h.
RutokenS returns data with little endian byte order, due to this
fact token wouldn't work with standard function. So function for
parsing fcp from little endian data was inplemented.
The maximum length for sending and receiving data can now be found in DO
7F66. For now, we just use the default values for short/extended length
capabiliites.
PKI-Applets may not be active if the card has been reset or unpowered.
The SELECT command used to activate the applet, is identical to the one
used during card matching or initialization.
Some "unfriendly" cards return SW 90 00 to any instruction including
the ACA file selection and therefore they are identified as CAC card.
To avoid this, we will try to read the assumed ACA file and we will
mark the card as matched only if we will read something from that file.
We do not parse the content yet.
To avoid infinite loop on "unfriendly" cards, we assume that
read data instruction always returns some data. It it does not,
we can safely assume the file is not there or it is not the card
we are looking for.
Windows/macOS (minidriver/tokend) handle the authentication status and
perform an explicit logout on shutdown. PKCS#11 standard requires a
session for logging into the card; when closing the session we perform
an explicit logout. Hence, the authentication status should be reset
even if not performing a reset on disconnect.
partially implements https://github.com/OpenSC/OpenSC/issues/1215
Refactored OpenPGP code so that future versions of the card will be
accessed using the logic for OpenPGP V2. We hope that backward
compatibility of the standard will keep the new versions functional.

Mingw currently links to msvcrt.dll as C runtime.
This library is documented by Microsoft as off-limits to applications and
its feature set vary between Windows versions.
Due to this, presence of particular printf() format string directives
depends on which Windows version the code is run.
This is, naturally, bad, so mingw developers introduced ability to replace
formatted output functions with built-in equivalents with defined feature
set by setting "__USE_MINGW_ANSI_STDIO" macro to 1.
There are, however, no built-in equivalents for "_s" suffixed functions.
Fortunately, they are used only a few times in minidriver so let's simply
replace them with equivalent code using standard functions.
This also allows skipping "MINGW_HAS_SECURE_API" macro definition so any
future uses will be caught by compiler.

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).

This commit fixes most of warnings shown by GCC on 64-bit Linux, 32-bit and
64-bit mingw builds (with SM and OpenSSL enabled).
These warnings were mostly caused by missing casts.
In minidriver there was also a bit of unused variables and dead code.
Remaining warnings on mingw are mostly caused by GCC not recognizing on
this platform "ll" size specifier (present at least since
Visual Studio 2005, also in mingw own CRT) and "z" size specifier (this one
will be fixed in next commits).
There is also a warning about pointer truncation on Win64 when making
PKCS#11 object handle from pointer to this object.
This is a legitimate warning, since it could result in the same handles
being generated from different pointers and so from different objects.

Issue #824
In Windows, file handles (including 'stderr', 'stdout') can not be shared
between DLL-s, and so, the log handle (File *), defined in one module, cannot
be reused in another.
That is the situation when, for example, the SM is processed
in external, dynamically loadable module as it currently implemented for
IAS/ECC card.
That's for the configuration option 're-open of log file on each message' was
introduced.
This 're-open' logic has not been tested in the particular case of opensc-*
tools used with verbose log into 'stderr' -- in dynamically loaded module the
'stderr' handle, defined in the 'main' module, was not recognized as 'stderr'
and there was an attempt to close it.

This mod is for non federal issued PIV cards. It will set PKCS#11 key attributes
based on the keyUsage extension from the coresponding certificates.
This mod applies to a PIV or PIV-like card without a CHUID or without a FASC-N
or a FASC-N that startes with 9999. A federal issued PIV card will have a CHUID
object with FASC-N that does not have the agency code 9999.
If the certificate does not have keyUsage,the current defaults will be used.
This avoids backword compatability issues with cards in the field.
To take advantage of this mod, make sure certificates have keyUsage extension.
This mod applies to all keys on the card including retiered keys.
The NIST 800-73 standards specify the key usage for each key and different keys
have different PIN requirements. This mod is designed to be used with PIV-like
cards or devices.

The OpenSC source can now use the OpenSSL 1.1 API. The libopensc/sc-ossl-compat.h
has defines for the new API for use with older versions of OpenSSL.
sc-ossl-compat.h is included by libopensc/internal.h so all OpenSC
library routines can take advantage of it. For the tools, which do not use
libopensc/internal.h, libopensc/sc-ossl-compat.h is included by the tools.
The OpenSC source has been modified to use OpenSSL functions to access
hidden structures, such X509, BIGNUM, EVP_CIPHER_CTX, and use XXX_new
functions to allocate structures which must use pointer such as
BIGNUM and EVP_CIPHER_CTX.
For backward compatability sc-ossl-compat.h now defines inline routines
to emulate the RSA and DSA access routines in OpenSSL-1.1.0. Thus
the same OpenSC source code can be used with openSSL versions from
0.9.7 to 1.1.0.
Inline routines were chosen, because using macros does not work on all platforms.
Having OpenSC versions of these routines in libopensc would be a posibility,
but they are only used for older version of OpenSSL, and could be removed in
the future.

Commit 2f10de4f5c ("use sc_pkcs15_get_pin_info in C_GetTokenInfo")
introduced dependency of logged in state returned for session
by C_GetTokenInfo() on logged_in field of that session slot PIN.
This field is updated by sending pin_cmd of type SC_PIN_CMD_GET_INFO to
card.
However, not all cards support such pin_cmd type (in fact, majority of
them don't). In this case logged_in field is usually left zero-initialized
which means SC_PIN_STATE_LOGGED_OUT.
With such logged_in field value C_GetTokenInfo() always returns
CKS_R{O,W}_PUBLIC_SESSION, instead of CKS_R{O,W}_USER_FUNCTIONS when
logged in.
At least Firefox (and probably other NSS-based software, too) is confused
by such value and keeps repeating PIN prompts a few times until it
ultimately considers that logging in to this slot has failed.
Fix this by initializing PIN logged_in field to SC_PIN_STATE_UNKNOWN for
cards that do not support SC_PIN_CMD_GET_INFO pin_cmd.

"CHANGE REFERENCE DATA" (PIN change) and "RESET RETRY COUNTER"
(PIN unblock) commands in OpenPGP card have various limitations.
These also depend on whether the card is version 1.x or 2.x.
Provide helpful debug messages for user in case he is trying to do
a PIN command in a way that isn't supported by the card.
Also, take into account that version 2.x cards don't support references to

The code attempted to handle extensions assuming extensions were ordered. The
only extension it handled was crl's, but the handling was wrong and I didn't
find any actual use of the crl code. I've changed it to cache all the extensions
and then provided accessors functions to read a specific extension. I needed this
to read the key Usage, but the extension fetching code can work with any extension
(though the caller will need to parse the result. I also added code that parses DN
and returns a specifically requested DN component. I needed this to get the Common
Name for the certificate Subject. This gives the token a 'unique' name rather than
some generic name (like CAC-I or CAC-II). Both of these can be used to enhance the
piv support as well.

Add card_reader_lock_obtained function to sc_card_operations
During sc_lock, if card->reader->ops->lock is called, card->ops->card_reader_lock_obtained will be called.
If PCSC is being used as the reader driver, this occures just after pcsc_lock has done a SCardBeginTransaction
and our process has exclusive control over the card. The card driver can then determine if the state of the
card has changed, and take action to get the card into an acceptable state.
If card->reader->ops->lock returns SC_ERROR_CARD_RESET, indicating some other process has interefered
with the state of the card. was_reset=1 is passed to card->ops->card_reader_lock_obtained.
Some examples of actions that could be done by the card driver is to select the AID and reset logged_in.
Currently the card driver is not notified. So no default card_reader_lock_obtained is defined in iso7816.c

Not all PIV cards follow the NIST 800-73-3 standard. This commit is designed to address some
of the issues. OpenSC developers don't have access to all the different versions of devices
or access to release notes for the devices to see when a bug was introduced and when it is fixed.
To make OpenSC code changes easier, the code is divided into four sections:
(1) Identify the card/token as best possible by looking at the "Historical bytes" in the ATR.
For the Yubico devices read their version number and log it via sc_debug.
(2) Define the card_issues CI_* defines in card-piv.c. There are 8 of them at the moment.
See below.
(3) based on the card->type and possibly Yubico version set the priv->card_issues flags that
apply to current card or device.
(4) Implement in the code changes needed for each issue.
Other issues can be added. As more info is obtained (3) can be updated using the version
number as needed.
The card issues are:
CI_VERIFY_630X - VERIFY "tries left" returns 630X rather then 63CX
CI_VERIFY_LC0_FAIL - VERIFY Lc=0 never returns 90 00 if PIN not needed. Will also test after
first PIN verify if protected object can be used instead
CI_CANT_USE_GETDATA_FOR_STATE - No object to test verification in place of VERIFY Lc=0
CI_LEAKS_FILE_NOT_FOUND - GET DATA of empty object returns 6A 82 even if PIN not verified
CI_OTHER_AID_LOSE_STATE - Other drivers match routines may reset our security state and lose AID
CI_NFC_EXPOSE_TOO_MUCH - PIN, crypto and objects exposed over NFS in violation of 800-73-3
CI_NO_RSA2048 - does not have RSA 2048
CI_NO_EC384 - does not have EC 384

resolves issue #735
This is a cleaner fix for #720 which take part of #721 and #730
A driver private struct is used which allow to remove all globals which might changed base on the token in use.
simclist.h is changed to either accept a predefined inline and/or
predefined restrict macro or tests for known compilers and sets
simclist_inline and simclist_restrict with the approprate keyword
for the compiler being used or defines them as blank.
The logic used is based on code in OpenSSL-1.1 e_os2.h
For example, "configure" could define inline and/or restrict.
But OpenSC is built on other platforms without a config.h and thus
changes to simclist.h are still needed.
simclist.c is changed by replacing inline with simclist_inline
and restrict with simclist_restrict.
The one and only use of inline in card-dnie.c is removed as there
is no need to have the function inline. This avoids any inline issues.
If inline is needed in other OpenSC code or in card-dnie.c,
simclist_inline could be used.
(Another option is to just remove all inline and restrict keywords
from OpenSC code.)

GemSAFE V1 cards support signing 36 bytes of free form data.
When signing a hash, the hash must be prepended by the DigestInfo
header. The PKCS#1 padding is done on the card. The 36 bytes limit
is sufficient for MD5 (16 + 18 bytes for the header), SHA1 and
RIPEMD160 (both use 20 + 15 bytes for the header) and MD5_SHA1
(16 + 20 bytes, no header). The algorithm reference ("cryptographic
mechanism reference" in ISO 7816 parlance) for signing free form data
is 0x12.
GemSAFE V3 cards changed the algorithm reference for signing free
form data to 0x02. In addition, they gained the ability to sign SHA256.
Since SHA256 exceeds the 36 bytes limit (32 + 19 bytes for the header),
it must be sent to the card *without* DigestInfo header. The header
will be prepended by the card and it is instructed to do so by sending
algorithm reference 0x42.
This scheme is also supported for SHA1, the algorithm reference is
0x12 in this case. However using this is not necessary as SHA1 fits
within the 36 bytes limit, including the header.
Supporting SHA256 is straightforward, we just add it to the flags
before adding the RSA algorithms. When sc_pkcs15_compute_signature()
calls sc_get_encoding_flags(), the input will be "iFlags 0x202, card
capabilities 0x8000021A" and the output will be "pad flags 0x0, secure
algorithm flags 0x202". I.e. the hash is neither prepended by the
DigestInfo header nor PKCS#1 padded and the hash algorithm is passed
to gemsafe_set_security_env() which can send the appropriate algorithm
reference 0x42 to the card.
However there's a catch: Once we add SHA256 to the flags, PKCS#11
applications will be unable to use the other hashes like SHA1 or
RIPEMD160. That's because register_mechanisms() checks if the card
supports no hashes, and if so, adds all of them:
if (!(rsa_flags & SC_ALGORITHM_RSA_HASHES)) {
rsa_flags |= SC_ALGORITHM_RSA_HASHES;
}
We cannot add these missing hashes to the flags like we did with SHA256
because like SHA256, they would be sent to the card *without* DigestInfo
header. What we want is to send all hashes *with* DigestInfo header,
*except* for SHA256.
We can achieve that by registering a fake RSA algorithm which includes
the missing hashes in its flags. This fake algorithm is never used
because sc_card_find_rsa_alg() searches the algorithm list in-order
and we register the fake algorithm *after* the real algorithms.
The fake algorithm persuades register_mechanisms() to register the
missing hashes because it ORs the flags of all RSA algorithms together:
num = card->algorithm_count;
while (num--) {
switch (alg_info->algorithm) {
case SC_ALGORITHM_RSA:
rsa_flags |= alg_info->flags;
break;
}
}
So when signing e.g. a RIPEMD160 hash and sc_pkcs15_compute_signature()
calls sc_get_encoding_flags(), the input will be "iFlags 0x102, card
capabilities 0x8000021A" and the output will be "pad flags 0x100, secure
algorithm flags 0x2". This will result in the hash being prepended by
the DigestInfo header, which is what we want.
pkcs15-piv.c was setting the auth_id of the public keys
which would cause some appications to require a login to access
a public key. The public keys are obtained from the certificates
which do not require the PIN to read.
Very early drafts of NIST 800-73 did require the PIN to access the
certificates, and the auth_id was removed in the opensc code for
certificates many years ago, but not from the public keys.

PIV cards uses get/put data not select file and read_binary.
To allow access via pkcs15 emulation card-piv.c emulates
select_file and read_binary but only when used with the path as
created by the piv emulation.
There are no MF.DIR or ED.DIR files.
opensc-tool and opensc-explorer will not work with this emulation.
Patch removes code that caused problems with opensc-tooland opensc-explorer.
card-piv.c was not selecting the PIV AID correctly from piv_find_aid.
This cause a CAC card that also has the PIV application to fail a VERIFY command
of the pin would use a VERIFY APDU P2 where P2 for PIV is 80, but for CAC was 00.
A CAC card could work if the caller requested the serial number of the card
which did call piv_select_aid. All the OpenSC tools, minidriver and
PKCS#11 do this, but Tokend does not.
This is a partial fix for https://github.com/OpenSC/OpenSC/issues/570.
Tokend in later MacOS versions still has other issues.
A more complete solution is needed for cards with multiple applications.
I do not have a CAC card or MAC to do any testing.
Thanks to https://github.com/mouse07410 who has a CAC card, and a Mac,
and has tested this fix.
Removed cmap_record in sc_pkcs15_prkey_info (not used by any driver nor code)
Remove cardcf specific code (cardcf neutralized by CP_CACHE_MODE_NO_CACHE and it maintened by the Base CSP/KSP, not the minidriver)
Add conversion code for Windows GUID / OpenSC self computed GUID
For ECDSA signatures, there are multiple ways to format the signature:
- R|S (R and S filled with zeroes at the most significant bytes)
- ASN1 sequence of R,S integers (e.g. used by OpenSSL).
It is rare that the filling with zeroes is needed.
But if it is, in the second case, the filling zeroes should not be there
or the verification of the signature by OpenSSL will fail.
in cases where you use pam_pkcs11, HOME might not be set
so paths based on $HOME are not usable, so that the combination
of home and caching does not work. Having the paths configurable
(together with a good setting of access rights)
resolves that problem.
The special value still needs to be handled for commands that are issued
during card initialization. This especially concerns T=0 cards that need
to use iso_get_response.
fixes#533
regression of 85b79a3332
This adds support for the Yubikey NEO. I'm not sure whether it breaks
the specification, or follows some other version of the spec, but in my
testing it returns SW1=0x63, SW2=0x0N for N PIN tries remaining.
Ignoring the top nibble seems a harmless change to the behaviour to
support this device.
This is already supported for a couple of the card drivers, but
since it's a general feature of ISO7816 it should go in iso7816.c,
rather than the current situation where identical code for this is
copy and pasted in each driver.
However, some cards apparently don't support this feature and count
it as a failed PIN attempt, so I've added a flag for now to indicate
whether the card supports this feature. It future, it could be moved
to blacklist cards rather than whitelist them, subject to more testing.
If the reader announces extended length support, but the card driver
leaves max_send_size/max_recv_size at `0`, max_send_size/max_recv_size
previously would have been overwritten with the reader's size though the
card might not have set SC_CARD_CAP_APDU_EXT. This commit fixes this
behavior.
Additionally card->max_send_size/max_recv_size is always initialized to
a value different from 0 after the card initialization. This removes the
need to check for this special value in all subsequent calls.

card-piv.c tries to read the first 8 bytes of an object to get object size
so it can allocate a buffer. It then reads the whole object. apdu.c has changed
over the years, and apdu.c will keep reading as long as the card returns
status of 61 XX thus apdu.c will read the whole object while discarding
the extra data and returning to the caller only the first part of the data.
This in effect causes a double read of objects.
This patch sets SC_APDU_FLAGS_NO_GET_RESP to tell apdu to stop doing the
extra get-response commands thus avoiding most of the extra overhead.
This in not an optimal patch as it only works with T=1 cards/readers
but the patch is confined to just card-piv.c.
A better patch is in the works.

minidriver: fix some code analysis warnings
Prior to 066132327c71300188aa66180fde2fb3d90c5140, CKM_ECDH1_DERIVE and
CKM_ECDH1_COFACTOR_DERIVE were always registered for cards that support
SC_ALGORITHM_ECDSA_RAW.
The mentioned commit changed this behavior, so that the ECDH mechanisms
are only registered for cards that set the SC_ALGORITHM_ECDH_CDH_RAW
capability flag.
To keep the existing behavior for the cards, they need to set this flag
in the card driver.
This patch fixes 3 issues which consecutively have shown up when debugging the original problem:
1 - Newer DNIe report a byte count for public certificates which is the compressed size,
while older DNIe report the uncompressed size. This resulted in short-reading the x509 certificates,
and in an error parsing. Therefore, during initialization we proceed to set path->count for
public certificates to -1. This ensures that the lenght of the certificates for reading
will be set to file-> length, which has the correct size.
2 - pkcs11-tool -t was broken for DNIe (old and new)as it tried to strip pcks11 padding
from the data to sign and OpenSC tried signatures with non-padded data
(as the card had SC_ALGORITHM_RSA_RAW).
The new algoflags (SC_ALGORITHM_RSA_HASH_NONE | SC_ALGORITHM_RSA_PAD_PKCS1) and the
removal of the strip-padding call fix the issue.
3 - The new cards won't allow setting the LE bytes when calculating the TLV, when LE equals
256. This caused an wrong SM object error response (0x69 0x88). Therefore,
we don't send the LE bytes anymore in this case.
The patch has been tested to work on the new problematic card and on another old one.

There are few Java Cards that do not support ECDSA at all.
Starting with IsoApplet version 00.06, the applet returns whether the card
supports ECDSA or not. This commit uses this information to decider whether to
register ECDSA mechanisms or not.
Recent BELPIC cards (issued since March 2014) have a validity of 10
years (rather than 5 as before), and therefore also increased the key
size from 1024 bits to 2048 bits.
Key size can be detected by checking the applet version, for which we
have to issue a "GetCardData" command. If the applet is version 0x17 or
higher, keys are 2048 bits.
Use #defines rather than magic numbers
Keeps the code slightly more readable.
While we're at it, refactor slightly so that the code which issues the
GET CARD DATA command doesn't just keep the applet version, but also
makes other things available.

It is required to strip excessive zeroes returned by some Java Cards when removeing the ASN1 structural information for PKCS#11 so that the x/y can be calculated by dividing the signature length by 2. However, the leading zero may only be stripped if it is excessive (outside the field length). Otherwise generated signatures are wrong in rare cases (1 out of 256).
See: 189e998486
The IsoApplet requires the host to do the hashes with RSA. OpenSC will
add all hashes that are available in software and will not expect the
card to do the hashing.
Rework the EC key generation mechanism to send the curve parameters to
the card. In earlier versions, the applet had a copy of the curve
parameters and there was a different algorithm reference for every
curve. This is unfeasible when trying to support a larger number of
curves because of size limitations of the applet.
This commit additionally includes some refactorings that should not
change the functionality.
needed to store information about EC curve supported by card.
Primary usage is when importing/generating key to get know if particular curve is supported by card.
sc_pkcs15_get_object_guid() should prefer the serial number from
EF(TokenInfo) over card->serialnr because the user may override the
card's serial number with "pkcs15-init -C --serial". The card->serialnr
should be used before calling card CTL with SC_CARDCTL_GET_SERIALNR
because it might contain a cached value.
This change *should* allow cards to be used with the minidriver even if
SC_CARDCTL_GET_SERIALNR is not implemented. For example, a driver might
set card->serialnr at initialization or the user might initialize a
PKCS#15 card with its own "--serial".

* With commit facaf59, access_flags were set for most cards. A closer look
revealed that this is already done in `sc_pkcs15emu_add_rsa_prkey`.
Therefore, this removes the duplicated code for cards calling this function.
Enhance sc_asn1_put_tag to support larger tag names and larger tags.
Prior to this, sc_asn1_put_tag did only support tags with a length of at most 127 bytes and tag names of one byte.
* Add default behavior for cards using the PKCS#15 emulation layer.
Hence, this patch provide a default value for access_flags compatible with
current OpenSC's behavior while allowing compatible cards to fetch the real
value from the card (IAS-ECC and AuthentIC).
Previously, partial DF name selection was used, which is not mandatory
to implement for a JCRE. We now use the full DF name which must always
be implemented.
Note that the MUSCLE applet is deprecated and should not be used.

framework-pkcs15: Duplicate public key related to private key rather than referencing the framework object
Referencing the related public key is required to return PKCS#11 attributes for a private key only available
in the public key object (i.e. CKA_MODULUS). This patch adds a copy of the public key to the private key object rather than
referencing the public key object in the framework. This prevents SEGV when the public key framework object
is deleted with C_DestroyObject, but the reference from the public key remains intact.
The bug leads to all kind of stability problems when keys are created and deleted in the same session.
The patch is in particular important if OpenSC is used with EJBCA or any other application using the
SUN PKCS#11 provider: When generating key pairs, then the public key object is eventually garbage collected
which removes the related object in the PKCS#11 module. Because there is no fixed time for this operation,
corruption occurs at random.
In a next step, the remaining related_xxx fields in sc_pkcs11_object should be revised and possibly removed.

Support nonces that are not only 8 bytes in
Mutual Authenticate. Use the witness length
to determine the nonce size, thus existing
systems using 8 bytes will continue to use 8
bytes. However, with AES 256, the nonces could
be a single block size of 16 bytes or greater.
This adds algorithm IDs 0xA, 0xA, 0xC which as documented
by the NIST PIV specification is algorithms AES-128, AES-192
and AES-256 respectively.
This patch also addresses some of the hardcodes that prevented
nonces greater than the single byte TLV length tags would allow.
It was explicitly tested with AES-256 and 256 byte nonces.

In old implementation, the DOs which their access is restricted by
PIN (like DOs 0101 -> 0104) were excluded from the fake filesystem,
leading to that we cannot read their data later, even if we verified PIN.
Contact cards have ATR-s, contactless not. Only contact
cards should be broken so that they answer 0x9000 to application
selection, so this should be failsafe.
I had some ideas on how to improve the experience for JavaCards
but that path did not get implemented further and my approach now
is very different.
While it would be nice if OpenSC (command line) detected
somehow blank JavaCard-s and informed the user that steps a-b-c
should be taken to make use of it, it doesn't really fit in.

The name implies what the format of the returned value, a SPKI.
The support for spki as a pkcs15 format of a pubkey, is extended to
work for any algorithm not just EC pubkeys. PKCS#15 appears to allow this.
sc_pkcs15_decode_pubkey_with_param will look for a SPKI
and attempt to use it for any algorithm, including RSA.
(RSA is the null case, as there are no algorithm parameters.)
sc_pkcs15_encode_pubkey_as_spki is exported from libopensc.
pkcs15-piv.c will use sc_pkcs15_encode_pubkey_as_spki to load public keys
as SPKI for RSA and EC.
The pubkey->data is never a SPKI, it is the DER encoding of the
pubkey without the parameters. If an spki is needed, use the
sc_pkcs15_encode_pubkey_as_spki to get the DER encoding of the spki.
As in the previous set of patches, pkcs15-tool.c will output both
sc_pkcs15_decode_pubkey_with_param and its internal.
This was left for testing, and the pubkey_pem_encode should be deleted
The original ECC code in OpenSC stored the ecpointQ as a DER encoded OCTET STRING.
Shortly before 0.13.0, code changes where made to store the ecpointQ as raw data
without the DER encoding.
Only some of the code was changed to support this but not all, and the comments
that said the ecpointQ was in DER where not changed either.
Some card drivers continued to work, using the original code in all place,
while some cards failed, as they where using a mixture of original code and
0.13.0 code.
This commit fixes these problems.
The ecpointQ is stored in raw format
A new structure type sc_pkcs15_u8 is defined.
The ecpointQ are changed to use the struct sc_pkcs15_u8. This was done to avoid
the confusion of using struct sc_pkcs15_der to hold non-DER encoded data.
(There may be other uses for this too...)
Comments are change is many places.
sc_pkcs15_decode_pubkey_ec was fixed to store the raw ecpointQ correctly.
sc_pkcs15_pubkey_from_spki was change to get the sc_ec_params from the alg_id
and fix up u.ec.params. Unfortunately the OpenSC code has two places EC parameters
are stored. They can get out of sync, or there may still be code
that looks in the wrng oplace. o(TODO get it to only only place.)
The u.ec.params.field_length is now set in a number of places, as this is need
in many of the PKCS#11 routines.
framework-pkcs15.c will now correctly return the DER encode ecpointQ,
for the CKA_EC_POINT attribute using pubkey->data which has the DER encoding
for the ecpointQ.
framework-pkcs15.c will look for the EC parameters in either the u.ec.params.der,
or in the alg_id->params. (TODO get it to only only place.)
pkcs15-myeid.c has some comments, as it looks like the code is storing a TLV
rather then a DER encoding of the ecpointQ. With the wrong encoding PKCS#11 will
return the wrong attribute for CKA_ECDSA_PARAMS.
pkcs15-piv.c is changed so emulation of a pubkey taken from a certificate will
work correctly.

From @geoffbeier:
(https://github.com/OpenSC/OpenSC/pull/171#issuecomment-20407132)
So it sounds like the right fix is to:
* check the return value of sc_ctx_log_to_file() and have sc_do_log_va()
return if it's anything other than SC_SUCCESS.
* Inside sc_ctx_log_to_file() make sure to set ctx->debug_file to NULL
whenever it does call fclose() on it.
* Inside sc_do_log_va() where it currently calls fclose() check
if(ctx->debug_file && ctx->debug_file != stdout &&ctx->debug_file != stderr)
* iso7816_check_sw() emits a "informational message" (from ISO7816-4 table 6)
* SW-s which are not known or not meaningful for internal API get translated
to SC_ERROR_CARD_CMD_FAILED by default, so use it also in the SW table
* Remove undefined SW-s and move generic SW-s to their sequential location.

New member keeps the value of the PKCS#15 DATA object.
Internal pkcs15 procedure that reads DATA object is modified
to check if requested data are already vailable in 'data-info',
an only then try to read the content of dedicated on-card file.
For some emulated PKCS#15 systems value of DATA object is kept as 'direct' value
in a proprietary attribute files and so the common read procedure could not be used.

For some cards that currently use the common iso-7816 operations
only SELECT with return of FCI/FCP can be applied.
In iso-7816 'select-file' handle, if 'SELECT without FCI' fails with error code 6A86,
then retry 'SELECT with FCI'. Other error code can be added.
Sorry for the 'coding style' noise.
In PukDF of PKCS#15 the public key value can be presented by 'direct value', by path or by path and reference.
For the different cards the public key can be stored in EF, internal EF or in card specific SDO (security data objects).
A new card handle allows to read out the public key from the card specific SDOs.
CK_VERSION is included into PKCS#11 data but is not specified by PKCS#15.
CK_VERSION can be provided by card's pkcs15 emulator or by the card's driver,
including the cards with the native support of pkcs#15 (and thus without pkcs15 emulator).
That's why the more general solution is to have these data included into 'sc-card' data type.
Thanks to Andreas Schwier.

In PKCS#11 FW, the 'certificate' FW object is used to create corresponding 'public'key' FW object
or to get some of its attributes.

'PACE' is extremely card specific protocol and has not to be ostensibly
present in the common part of OpenSC:
* currently in OpenSC there is no card driver that supports or uses this protocol;
* amazing content of the common 'sc_perform_pace' -- beside the verbose logs
the only substantial action is to call the card/reader specific handler.
According to the current sources and the pull request 83
this 'common' procedure is called by the card driver or
card specific tool/operation.
* currently the 'PACE' can be thouroghly tested only by one person (Frank Morgner),
and only using the OpenSSL patched with the PACE specific patch.
So, at least a dedicated configuration option could be introduced when comiting PACE to the common part.
* common 'sc_perfom_pace' has the same role as the 'initialize-SM' handler of the existing SM framework
and can be implemented as card specific SM, as the others cards do.
This confirmed by Frank Morgner, the author of PACE commits and nPA card driver, himself.

According to ch.4.2 of MyEID reference manual v1.7.6 the only possible value of P2 of 'SELECT' APDU is '00'.
For this reason, when caller do not request to return 'sc_file' data,
use the non-null dummy 'sc_file' pointer in the call of iso->select_file,
and thus avoid the P2 different from '00'.
Also log calls are replaced by its short forms,

But this certificate is bound with authentication key, so when decrypting,
the authentication key will be presented to check.
This commit allows to bypass the check in driver. However, it is not enough.

CKA_ALWAYS_AUTHENTICATE implies CKU_CONTEXT_SPECIFIC login, but all this
key really should need is a C_Login with CKU_USER.
The historical reason for having CKA_ALWAYS_AUTHENTICATE set was to keep
Firefox/NSS from using that particular key for SSL connections. However,
starting with Firefox 8, NSS ignores Non Repudiation certificates for
SSL and that makes the CKA_ALWAYS_AUTHENTICATE workaround unnecessary.
Now that Firefox is fixed, drop the workaround in OpenSC so that
applications that follow the pkcs11 spec wouldn't have to login twice to
access the key.
For some cards some APDUs are always transmitted in a plain mode,
even if SM session is opened.
For these APDUs the 'get_sm_apdu' card's handler returns SUCCESS without wrapped APDU version.
