Zoltan Kelemen 6e3e81a9f4 Remove unused stored_length field. 2020-08-19 10:01:58 +02:00
Zoltan Kelemen 48d939b057 Removed length_offset since it is not used any more. 2020-08-19 10:01:58 +02:00
Zoltan Kelemen aca0d08e29 Removed the 'crts' field from 'sc_acl_entry' type since:
- its definition is specific to the IAS-ECC card type
- its presence can not be assumed since it is read from non-mandatory SE type of an SDO
- it is currently not used anywhere in the code

Frank Morgner 978c912c70 fixed Heap-buffer-overflow READ
7cf8087351 seemed to be incomplete. Change
the length of the buffer right before it's accessed.

Julian Strobl 9ffb9bae63 tcos: add missing encryption certificates 2020-07-30 02:00:15 +02:00
Zoltan Kelemen 2b78374e37 Print error message for the case that a PUK object is not available for a PIN
during an unblock operation (this is a sign of a card with invalid PKCS #15
info). Without this error message the program just terminates silently, which
is confusing to the user.
2020-07-22 22:58:57 +02:00
Zoltan Kelemen 6f1df6454a Reject the case that the PIN and PUK padding flags are different, since this
case can not be handled by the card driver interface. Better to detect and
fail early instead of sending invalid data to the card.
2020-07-22 22:58:57 +02:00
Zoltan Kelemen 555cb73615 Fix for using the correct info for PIN/PUK (before they were switched). 2020-07-22 22:58:57 +02:00
Zoltan Kelemen e80906d973 Add path selection to sc_pkcs15_get_pin_info to make it work correctly with
local PINs. This makes the code behave the same way as PIN verification,
change and unblock, before calling the PIN command handler in the card driver.
2020-07-22 22:58:57 +02:00
Zoltan Kelemen bad74e1ed6 Enabled code for using PUK reference for PIN unblock, when available. 2020-07-22 22:57:23 +02:00
Zoltan Kelemen 998284dd1c Removed unused define. 2020-07-22 22:57:23 +02:00
Zoltan Kelemen ba76bc0239 Improved syntactic readability without any change in functionality. 2020-07-22 22:57:23 +02:00
Zoltan Kelemen c903ddfce1 Fixed bounds checking and enabled the function again. 2020-07-22 22:57:23 +02:00
Zoltan Kelemen 163b69e6a7 Change ADF selection to return FCP for Oberthur cards. No need to simulate
since it is supported.
2020-07-22 22:57:23 +02:00
Zoltan Kelemen 3331a7f134 Fix MF selection APDU to use 0x0c in P2 (no data). The previous value of 0x00
is invalid according to IAS-ECC and resulted in 6A 86 on the Oberthur
cards that we tested with.
2020-07-22 22:57:23 +02:00
Zoltan Kelemen 471468260e Improved PIN unblock function:
- Uses PIN padding from merged policy
- Added PIN-pad support
- Use ISO 7816 layer to avoid code duplication
2020-07-22 22:57:23 +02:00
Zoltan Kelemen 79e81eeef0 Improved PIN change function:
- Uses PIN padding from merged policy
- Improved PIN-pad logic and merged here from separate function
2020-07-22 22:57:23 +02:00
Zoltan Kelemen 5ae488c1b9 Improved PIN verification function:
- Uses PIN padding from merged policy
- Moved PIN-pad logic into this function instead of keeping separate
2020-07-22 22:57:23 +02:00
Zoltan Kelemen d0b3e90431 Simlified low-level CHV verification function:
- Removed special PIN-pad case, moving logic into high-level function.
- Use ISO 7816 layer to avoid code duplication.
2020-07-22 22:57:23 +02:00
Zoltan Kelemen 8c2d629f94 Functions used to control PIN padding and PIN pad use:
- Use PIN padding information when provided by upper layers
- Enable PIN padding at card level when min/max len set to same, nonzero value
- Allow PIN-pad use to be dynamically selected for each PIN
2020-07-22 22:57:23 +02:00
Zoltan Kelemen ca911e342c Improved PIN info retrieval, now returning verification status, and attempts
left even when previously not available (due to card not providing it in the
SDO).
2020-07-22 22:57:23 +02:00
Zoltan Kelemen 19063932f0 Simplified PIN policy retrieval to only read the data that is actually needed,
excluding the CRT info from the SE-SDO, which is not guaranteed to be
available in all card types.

Use an explicit PIN policy structure type instead of keeping the info in the
sc_pin_cmd_data, since this type of info is only used privately in the card
driver.
2020-07-22 22:57:23 +02:00
Zoltan Kelemen 741ee73ec9 Add generic function for PIN status retrieval, for subsequent use (among
others intended to replace iasecc_pin_is_verified).

Base it on functionality in the ISO 7816 layer to avoid code duplication.
2020-07-22 22:57:23 +02:00
Zoltan Kelemen 7ed876c816 Added ATR mask for Idemia (Oberthur) IAS-ECC card to recognize Cosmo V8 cards. 2020-07-22 22:57:23 +02:00
Zoltan Kelemen eb3e00a385 Corrected highly misleading, confusing and ambiguous use of PIN length_offset
field. Now only the PIN offset fields are used. Also added error checking for
invalid values.
2020-07-22 22:56:09 +02:00
Zoltan Kelemen 80853bda31 Only enable static frame size for PIN padding when padding length is below
maximum limits. Otherwise resort to adaptive support.
2020-07-22 22:56:09 +02:00
Zoltan Kelemen afffeccc29 Fixed problems with PIN min/max length handling:
- The wrong PIN was selected from the sc_pin_cmd_data structure.
- When the PIN max value was zero from the caller (meaning unknown max), the
  reader max value was not used.
2020-07-22 22:56:09 +02:00
Zoltan Kelemen 1dc359cb61 Fix for issue #1999:
- Reset context to undefined handle value on error since call may alter
  output parameter.
- Continue to assume -1 as undefined handle value in all PCSC
  implementations, to keep this fix as small and surgical as possible.
