2020-11-27scd: New getinfo sub-command apdu_strerror.Werner Koch1-2/+7
* scd/apdu.c (apdu_strerror): Add missing status codes. * scd/command.c (cmd_getinfo): New sub-command apdu_strerror. -- This is quite handy for gpg-card's APDU command and avoids that we need to duplicate the mapping table or put it into a shared file.
2020-11-11scd: Do not print reader status change with --debug cardio.Werner Koch1-1/+1
-- ... but use --debug reader for this. Signed-off-by: Werner Koch <[email protected]> (cherry picked from commit bd3b698d8ec427a02f2fa793777f2a88bc356f25)
2020-11-05scd: Use lock_slot for apdu_send_direct.NIIBE Yutaka1-1/+1
* scd/apdu.c (apdu_send_direct): Use lock_slot. -- With trylock_slot, it may return SW_HOST_BUSY. This may occur when apdu_get_status is called by scd_update_reader_status_file. Simply using lock_slot is much easier for user of apdu_send_direct. Signed-off-by: NIIBE Yutaka <[email protected]>
2020-09-28scd: Internal CCID: Clear the handle after use.NIIBE Yutaka1-1/+5

2020-09-25scd: For PC/SC, send the ESC command at init for SPR532 reader.NIIBE Yutaka1-25/+32
* scd/apdu.c (struct reader_table_s): Remove is_spr532. (pcsc_vendor_specific_init): Send the ESC command for SPR532. (pcsc_pinpad_verify, pcsc_pinpad_modify): Remove no_lc hack. -- The "no_lc" hack lets PC/SC-lite send the ESC command for SPR532 internally, for pcsc_pinpad_verify. However, PC/SC-lite doesn't do that for pcsc_pinpad_modify, unfortunately. Besides, I'm not sure this hack works on Windows, which has different implementation of PC/SC service. It's better to send the ESC command by the driver explicitly, at the initialization. Sending the ESC command results PCSC_E_NOT_TRANSACTED error when a card is not active (that is the case, usually). We ignore this error. Signed-off-by: NIIBE Yutaka <[email protected]>
2020-09-04scd: Increase the number of supported readers from 4 to 16.Werner Koch1-1/+2
-- The limit on 4 readers I introduced in 2003 is too low for some of our use cases. 16 looks better. TODO: Return a useful error message in gpg-card if the limit has been reached. Signed-off-by: Werner Koch <[email protected]>

Instead of checking a version number, we enable them depending on macros set by recent gpg-error versions. Eventually the whole divert stuff can be removed. The -Wno-format-zero-length is required because log_printhex can be called with an empty format string. Note that this is fully specified standard C behaviour.
