In the OpenPGP card specification, there are multiple options to

implementation support which option and there is no way (yet) for card
to express itself which key attributes are supported, we haven't
supported key attribute change back to RSA. But, many card
implementation uses P and Q, try this option. If other cases,

This fixes a potential overflow if LFs are passed to the status

because neither the truncating in libassuan or our escaping is not the
Right Thing. In any case the functions need to be more robust and
comply to the promised interface. Thus the code has been factored out
to a helper function and N has been bumped up correctly and checked in
all cases.
For some uses this changes the behaviour in the error case (i.e. CR or
LF passed): It will now always be C-escaped and not passed to
libassuan which would truncate the line at the first LF.

Actually, when the incorrect expected response length (i.e. Le
field) is transmitted to the card, the card's answer is missing a
byte (i.e. ... 6101) so an additional command has to be sent to the
card to retrieve the last byte. Using the correct length avoids to
send the additional command to retrieve the missing byte, when the
computed length is wrong.
Note that an value of 65537 for E is pretty standard and thus we can
avoid the 6101 return code inmost cases.

Signed-off-by: Werner Koch <wk@gnupg.org>
* scd/apdu.c (apdu_close_reader): Call CLOSE_READER method even if we
got an error from apdu_disconnect.
* scd/app-common.h (no_reuse): Remove.
* scd/app.c (application_notify_card_reset): Deallocate APP here.
(select_application, release_application): Don't use NO_REUSE.
--
Reproducible scenario: Invoke gpg --card-edit session from a terminal.
Invoke another gpg --card-edit session from another. Remove a token.
Insert a token again. Type RET on both terminals. One of terminal
answers "Conflicting usage".
Perhaps, having NO_REUSE field was to avoid race conditions. Now,
APP can be safely deallocated by application_notify_card_reset.
Thanks to the2nd.
* scd/app-openpgp.c (get_public_key): Improve error handling.

* scd/ccid-driver.c (bulk_out): Use LIBUSB_ERRNO_NO_SUCH_DEVICE.
--
With libusb-compat library, the error is different than original
libusb. (The libusb-compat library is used by Fedora.)
* scd/ccid-driver.c (CCID_CMD_TIMEOUT): New.
(ccid_transceive_apdu_level, ccid_transceive): Use.
--
It is reported that key generation causes timeout with OpenPGPcard
v2.1. Ideally, timeout value could be determined at run-time by
examining card's ATR. Compile-time fixed value is OK for internal
CCID driver.
* scd/app-openpgp.c (change_rsa_keyattr): New.
(change_keyattr_from_string): Use change_rsa_keyattr.
(rsa_writekey): Call change_rsa_keyattr when different size.
(ecc_writekey): Try to change key attribute.
* agent/cvt-openpgp.c (get_keygrip): Handle Curve25519.
(convert_secret_key, convert_transfer_key): Ditto.
* common/openpgp-oid.c (oidtable): Add Curve25519.
(oid_crv25519, openpgp_oid_is_crv25519): New.
* common/util.h (openpgp_oid_is_crv25519): New.
* g10/ecdh.c (pk_ecdh_encrypt_with_shared_point): Handle the case
with Montgomery curve which uses x-only coordinate.
* g10/keygen.c (gen_ecc): Handle Curve25519.
(ask_curve): Change the API and second arg is to return subkey algo.
(generate_keypair, generate_subkeypair): Follow chage of ask_curve.
* g10/keyid.c (keygrip_from_pk): Handle Curve25519.
* g10/pkglue.c (pk_encrypt): Handle Curve25519.
* g10/pubkey-enc.c (get_it): Handle the case with Montgomery curve.
* scd/app-openpgp.c (ECC_FLAG_DJB_TWEAK): New.
(send_key_attr): Work with general ECC, Ed25519, and Curve25519.
(get_public_key): Likewise.
(ecc_writekey): Handle flag_djb_tweak.
--
When libgcrypt has Curve25519, GnuPG now supports Curve25519.
* common/openpgp-oid.c (openpgp_oid_to_curve): Add CANON argument.
* common/util.h: Update.
* g10/import.c (transfer_secret_keys): Follow the change.
* g10/keyid.c (pubkey_string): Likewise.
* g10/keylist.c (list_keyblock_print, list_keyblock_colon): Likewise.
* parse-packet.c (parse_key): Likewise.
* scd/app-openpgp.c (send_key_attr, get_public_key): Likewise.
--
Change the function so that caller can select canonical name of curve
or name for printing. Suggested by wk.
* scd/app-openpgp.c (send_key_attr): Send KEYNO.
(get_public_key): Fix SEXP composing.
(ecc_writekey): Fix OID length calculation.
(ecc_oid): Prepend the length before query.
(parse_algorithm_attribute): Handle the case the curve is not available.
* common/util.h: Provide replacement for GPGRT_ATTR_ macros when using
libgpg-error < 1.20.
* common/mischelp.h: Ditto.
* common/types.h: Ditto.
--
Given that libgpg-error is a dependency of all GnuPG related libraries
it is better to define such macros at only one place instead of having
similar macros at a lot of places. For now we need repalcement
macros, though.
* g10/call-agent.h (struct agent_card_info_s): Add curve field.
* g10/call-agent.c (learn_status_cb): Use curve name.
* g10/card-util.c (card_status): Show pubkey name.
* scd/app-openpgp.c (struct app_local_s): Record OID and flags.
(store_fpr): Use ALGO instead of key type.
(send_key_attr): Use curve name instead of OID.
(get_public_key): Clean up by OID to curve name.
(ecc_writekey): Support any curves in libgcrypt.
(do_genkey, do_auth, ): Follow the change.
(ecc_oid): New.
(parse_algorithm_attribute): Show OID here.
* g10/card-util.c (do_change_keysize): Put "rsa".
* scd/app-openpgp.c (change_keyattr, change_keyattr_from_string):
Change the command format.
(rsa_writekey): Check key type.
(do_writekey): Remove "ecdh" and "ecdsa" support which was available
in experimental libgcrypt before 1.6.0.
* scd/Makefile.am (sc_copykeys_*): Remove.
* scd/sc-copykeys.c: Remove.
* scd/pcsc-wrapper.c: Remove.
* scd/{card-common.h,card-dinsig.c,card-p15.c,card.c}: Remove.
--
sc-copykeys doesn't work any more because it's based on old API.
pcsc-wrapper has gone because of nPth which is compatible to pthreads.
The card* files are old files, now we have app*.
* g13/g13.c: Make use of debug_parse_flag.
* scd/scdaemon.c: Ditto.
* sm/gpgsm.c: Ditto
* agent/gpg-agent.c: Ditto. But do not terminate on "help"
* dirmngr/dirmngr.c: Ditto.

* scd/adpu.c (pcsc_pinpad_verify, pcsc_pinpad_modify): Bigger buffer
for TPDU card reader.

GnuPG-bug-id: 2003, 2004
This is needed for PC/SC on Debian Jessie. Note that it's not only
for Cherry ST-2000, but also, for any TPDU card readers.
* scd/apdu.c (pcsc_vendor_specific_init): Set pinmax to 15.
* scd/ccid-driver.c (ccid_transceive_secure): Add zero for the
template of APDU.

GnuPG-bug-id: 2003, 2004
* scd/apdu.c (open_pcsc_reader_direct): Partial string match.
--
The card reader name by PC/SC service might include USB bus,
which varies (on some platform like GNU/Linux). Thus, it's
better to match partial string.
Original patch was submitted by anstein. I changed it to fallback to
the first reader if no match found.
Note that we need to change pcsc-wrapper.c in 2.0 backport.
