That makes it easier to read.  An open question is whether we should

This has been tested with a D-Trust card featuring 3072 bit keys.
Note that non-repudiation key for a qualified signature does not yet
work because we do not yet support rsaPSS padding.  Thus a gpgsm
--learn shows a couple of Bad Signature errors for this key.

The card under test is a "Test-Signaturkarte D-TRUST Card 3.1" for a
mere 49 Euro and no specs available.  D-Trust is a branch of the
German Bundesdruckerei.  Compare that to Telesec and Yubikey who have
always been nice enough to send bunches of sample cards without a need
to wade through lots of forms and not even asking for money.  Guess
which cards I prefer.

--

There is no need to read the list of options from the components
unless they convey a default value.  It is better to consult only the
list we have in gpgconf-comp.c to decide on whether an option should
be displayed.   Right, this might mess up thing if a newer gpgconf
version is used with an older component, but we already print warnings
in this case and in general we do not want to support this anymore -
the times of gpg 1.4. and 2.0 are long over now.

Note that some of the changes are required because we can't rely that

Testing the PIN cache can currently only be done my modifying the

has been done.  Clearing the PIN cache is also not fully
implemented.  With the forthcoming changes to app-piv we should be
enter able to test the PIN cache.

Missing stuff:
 - The agent should be able to selectively clear the cache on a per
   slot base.
 - We should replace AESWRAP by OCB.

This change does away with encrypting and decrypting the cached PIN in
the agent.  There is no need for this we can simply cache the
cryptogram and let scdaemon decrypt after retrieving it from the
agent.  This way we do not need to share a key between gpg-agent and
scdaemon and further the cached content is invalid after the scdaemon
process has been replaced.

* scd/app.c: Chnage all function dispatcher.
--

This change will allow us to easier integrate an app swithcing logic.
The change should have no user visible effect.  The error checking we
do now with the card locked will rarely be asserted.  It is the
correct thing to do anyway.

There was the card-timeout option in GnuPG 2.0, but it was never
implemented correctly.  The intention of this option was to allow
sharing smartcard among multiple applications, but this didn't work
well as user's expectation (it only worked with DISCONNECT command).
This is because other parts of scdaemon assumes exclusive access.  In
GnuPG 2.1, the support of the option was removed, improving
"DISCONNECT" command always works well without this option.

This has been tested with gpgsm and RSA keys.  For ECC keys only

because gpgsm does not yet support ECC certificates and thus we can't
write the certificates to the cert object after a writekey.  Note that
they nevertheless show up in "gpgcard list" because gpg-card searches
for them in gpg and gpgsm.  However, this does not work completely.

This handling is not mondatory, but it's better to do so, because

User interaction status should be reset at open time.  The status

since cleanup routine in a driver may not be called properly, it's
good to submit SET_INTERFACE at open time.

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
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.

This patch enables the use of the log function from libgpgrt (aka

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

done after registration of APP.

When the setup is done just after opening the USB connection (before
issuing PC_to_RDR_IccPowerOn), a reader might notifies about no card
availability (because of not yet powered on), even though the card is
ready to be powered on.

  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.

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.
