* scd/app-openpgp.c (verify_chv2): Call verify_a_chv with chvno=1
when needed.

--

Confusingly, verify_chv2 has two different purposes;  One for
verifying with CHV2 (in addition to CHV1), and the call by
CHECKPIN.  For the latter, we should check CHV1.

This can be used with gpg-card to write the 3 extra certificates of a
Telesec TCOS Signature Card v2.  The card with the qualified signature
is distributed with the keys for encryption and advanced signatures
but without the certificates.  The certificates can be downloaded from
the website after an mail confirmation.  Unpacked the downloaded
zipfile has these certificates:

  auth_zert.crt
  sig_zert.crt
  enc_zert.crt

Using gpg-card issue these commands:

 writecert NKS-NKS3.4531 <sig_zert.crt
 writecert NKS-NKS3.45B1 <enc_zert.crt
 writecert NKS-NKS3.4571 <auth_zert.crt

Don't mix that up, tight now there is no checking that the
certificates match the public key.  I also need to write another patch
to actually implement signing and encryption with these nistp256
certificates.

scd: Fix Yubikey app switching problem
* scd/app.c (select_all_additional_applications_internal): Re-select

--

Usually keygrip based access to the Yubikey does a switching back and
forth and thus keeps the card and scdaemon's internal state in sync.
However, if we do only a listing scdaemon did not reselect the first
application (e.g. OpenPGP) after adding other applications (e.g. PIV)
and thus led to wrong info returned in a listing.

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

has been done.  Clearing the PIN cache is also not fully

scd: Use a scdaemon internal key to protect the PIN cache IPC.
* agent/call-scd.c (handle_pincache_put): Do not decrypt.

(inq_needpin): Call it.
* scd/command.c (set_key_for_pincache): New.
(pincache_put): Restructure and set key.
(pincache_get): Ditto.
--

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.

Using the enum is wrong because a string is expected.  However it did

Better safe than sorry.

We should also review the card reference counting to see whether we
better ref the returned card object already here.

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.

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

since cleanup routine in a driver may not be called properly, it's

In the OpenPGP card specification, there are multiple options to

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.

When GET_DATA returns no data with success (90 00), this routine
firstly returned buffer with length zero, and secondly (with cache)
returned NULL, which is inconsistent.  Now, it returns NULL for both
cases.

gpgrt_logv_prefix.  Change all callers.

callers.
(log_printhex): Move first arg to end so that this function matches
its printf like counterpart gpgrt_log_printhex.  Change all callers.

gpgrt_log functions.
(bug_at): Add inline versions if we can use the gpgrt_log functions.
* configure.ac (GPGRT_ENABLE_LOG_MACROS): Add to AH_BOTTOM.
(mycflags): Add -Wno-format-zero-length.
--

This patch enables the use of the log function from libgpgrt (aka
libgpg-error).  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.

We can use the interrupt transfer to be notified about card status
change.  In this case, we don't need to issue PC_to_RDR_GetSlotStatus
command.  This change improve the setup the notification; it should be
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.
