Hi! Currently, sc_check_apdu checks the length of an R-APDU buffer using SC_MAX_APDU_BUFFER_SIZE, which defines the maximum length for a C-APDU. https://github.com/OpenSC/OpenSC/blob/master/src/libopensc/apdu.c#L415 https://github.com/OpenSC/OpenSC/blob/master/src/libopensc/apdu.c#L392
A quick fix would be to use 0xff+1/0xffff+1 instead. However, in multiple files I have seen this wrong usage of SC_MAX_APDU_BUFFER_SIZE (eg, see `grep rbuf *.c | grep SC_MAX_APDU_BUFFER_SIZE`). Unfortunately I dont have time to check libopensc in depth, so I leave this up to the community. -- Frank Morgner Virtual Smart Card Architecture http://vsmartcard.sourceforge.net OpenPACE http://openpace.sourceforge.net IFD Handler for libnfc Devices http://sourceforge.net/projects/ifdnfc
