Jakub Jelen aacac57230 Another note/todo about PINs on uninitialized cards 2018-06-11 22:31:44 +02:00
David Ward fff4ca901d Provide more space for card holder name in CAC token label
The PKCS#15 emulation layer for the CAC uses a single PIN. Set its
label to "PIN" (rather than the card type "CAC I" or "CAC II"), so
that the PIN label will be omitted from the token label, providing
more space for the card holder name instead.

This is intended to match the behavior used for PIV cards, which
was changed with commit 56c8f59b25.

Nathaniel Wesley Filardo 00535f0174 sc_pkcs15_get_bitstring_extension: int, not long long
Use the ASN.1 decoder's SC_ASN1_BIT_FIELD decoder to properly decode
into a machine word.  As _bitstring_extension is used only for the OID
2.5.29.15 by all callers, which is at most 9 bits wide, this is a
reasonable thing to do.

Nathaniel Wesley Filardo 5882df745a Use |, not ||, when decoding CAC key_reference
This quiets two compiler warnings and is almost surely what was actually
meant.  However, I do not have a CAC card to test.

Maciej S. Szmigiero 62cbda6cd9 Fix log messages format and parameter issues flagged by GCC
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).
