Note that ECDH decryption has not been tested due to the lack of ECC
support in gpgsm.

* scd/app-piv.c (concat_tlv_list): New.
(get_key_algorithm_by_dobj): Rename args for clarity.
(do_auth): factor all code out to ...
(do_sign): new. Implement RSA signing.

* scd/app-piv.c (struct genkey_result_s): Remove type and all users.
(send_keypair_and_cert_info): Print certinfo only if we got a cert..
(readcert_by_tag): Add arg r_mechanism and implement reading of public
keys.
(get_keygrip_by_tag): Use a public key to compute the keygrip.
(do_readcert): Make sure to only return a certificate.
(do_readkey): Read public key from the DO if a certificate is missing.
(get_key_algorithm_by_dobj): Get the algorithm also from a public key.
(does_key_exist): String changes.
(do_genkey): Remove result caching and store public key in the DO.
--
This removes the result cache and instead stores the public key in the
certificate object. This allows to properly list public keys at any
time after generating a key and before a new certificate is stored
there.

(iso7816_generate_keypair): Add new args p1 and p2.
* scd/app-openpgp.c (do_genkey): Adjust for changes.

The OpenPGP card creates keys according to parameters read from a data
object. Other cards we are about to implement require a direct
specification of the requested keytype. This patch implements the
required changes.

The generic keyref allows for better error detection in case a keyref
is send to a wrong card.

* scd/app-openpgp.c (do_setattr): Add new table item to flush a
different tag.
--
For whatever reasons the OpenPGP card reads the 3 CA fingerprints from
one object but sets them individually using 3 different tags. The
cache flushing was not prepared for this and so a changed CA
fingerprint showed only up after a card reset. This patch fixes it.
Signed-off-by: Werner Koch <wk@gnupg.org>
* scd/app-openpgp.c (do_change_pin): Implement handling
APP_CHANGE_FLAG_CLEAR.
--
It is specified in the specification version 3.1 or later. Some
version 2 cards (including Gnuk) support this feature. Any version 1
card has no support for this feature.
For CHVNO = 1, it clears for both of 81 and 82; That is, user's key
usages for signing and others (decryption and auth).
For CHVNO = 3, it clears for 83, admin key.
For CHVNO = 2, it clears 82; That is, user's key usages
others (decryption and auth).

Detect the PIV application.
(get_supported_applications): Add "piv".
--
Right now this allows the use of the authentication key (9A) for SSH
authentication. More support will follow soon.
Tested with Yubikey-5.

arg.
--
iso7816_general_authenticate will be used for the PIV card support.
The new arg to iso7816_apdu_direct and apdu_send_direct allows to get
the raw status word back without the need to handle an output buffer.

* scd/command.c (cmd_readkey): Reformat for advanced mode.

The --advanced option used to work only if the driver supported that
but not if we extracted the public key from an x.509 certificate.
This patch fixes that.

* scd/app.c (app_new_register): Don't lock APP_LIST_LOCK here.
(select_application): Lock with APP_LIST_LOCK earlier.
--
What we want to do here is to serialize the call of
select_application. In the old code, it was possible
that a call of select_application was blocked internally,
and then another call of select_application entered.
We can have a dedicated lock for call of select_application,
but it is easier to re-use APP_LIST_LOCK.

We have a corner case: In "not forced" situation and authenticated,
and it is changed to "forced", card implementaiton can actually accept
signing, but GnuPG requires authentication, because it is "forced".

--
Gnuk has "admin-less" mode. To support "admin-less" mode with KDF
feature, salt should be same for user and admin. Thus, I introduce a
valid use of single salt.

* scd/app-openpgp.c (change_rsa_keyattr): Try usual RSA.
--
In the OpenPGP card specification, there are multiple options to
support RSA (having P and Q or not, etc.), and it is implementation
dependent. Since GnuPG doesn't have knowledge which card
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,
factory-reset would be easier option.

For new thread, signal mask is inherited by thread creation.
Thus, it is best to setup signal mask just after npth_init.

* scd/ccid-driver.c (intr_cb): Try submitting INTERRUPT urb
to see if it's suspend/resume.

Upon suspend/resume, LIBUSB_TRANSFER_NO_DEVICE is returned, since all
URBs are cancelled. We need to see if it's real NODEV error or its by
suspend/resume. We can distinguish by sending URB again.

* configure.ac (require_pipe_to_unblock_pselect): Default is "yes".
* scd/scdaemon.c (scd_kick_the_loop): Minor clean up.
--
Normally SIGCONT or SIGUSR2 works for unblocking pselect. But on my
machine with GNU/Linux, when a machine is suspend/resume-ed, pselect
keeps blocked, while signal itself is delivered.
It's better to use pipe.

Return SW_HOST_NO_READER when PCSC_STATE_CHANGED.
* scd/scdaemon.c (handle_connections): Silence a warning.
--
To detect some change of card status, including suspend/resume
possibly, SCardGetStatusChange should be used keeping the
dwCurrentState field.
This change could improve situation for suspend/resume with Yubikey on
Windows. Even not, this is doing the Right Thing.

--
This fixes a potential overflow if LFs are passed to the status
string functions. This is actually not the case and would be wrong
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.
