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.
There's a copy-and-paste bug in there, where the CKA_PRIVATE attribute
is being set on the wrong variables! As well as fixing that, we should
explicitly set CKA_PRIVATE to "false" for certificates and public keys,
since the PKCS#11 spec doesn't specify a default and some drivers use
"private" as the default, making it impossible to add a public key/cert
using pkcs11-tool.
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.

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
The PKCS#11 Usage Guide, at least up to v2.40, says that calling
C_Initialize() in the child after fork is "considered to be good
Cryptoki programming practice, since it can prevent the existence of
dangling duplicate resources that were created at the time of the fork()
call."
(It neglects to mention that doing so in the child of a multi-threaded
process is a clear violation of POSIX, mind you. Not to mention being
utterly pointless if all you're going to do in the child is exec something
else anyway.)
Regardless of the sagacity of this recommendation, we need to cope when
it happens. Historically, we've been quite bad at that. Let's add a test
to pkcs11-tool in the hope it'll help...
Fixes#464
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.

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.
Prior to this commit, all hashes registered for RSA or other key types were
registered for ECDSA as well.
register ECDH mechanism only when supported by card
ECDH should only be registered if the card driver sets the
SC_ALGORITHM_ECDH_CDH_RAW flag.
register software PKCS#1 (1.5) padding only when RAW RSA is supported by card
If OpenSC supports PSS/OAEP padding or other padding mechanisms in
future, and there would be a card that enforces hardware PSS/OAEP
padding, the PKCS#1 v1.5 padding mechanism should not be registered.
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.

fix#445
In OpenSC the EC field_length is the number of bits in the field.
Most curves have a field_length which is a multiple of 8 bits
but there are many that are not.
The X and Y points and privateD are stored in octetstrings
so there may need to be an extra byte in the octetstring.
An OpenSSL BIGNUM will drop leading zero bytes, so its size can not be used
to determine the field_length.
