scd: New standard attributes $ENCRKEYID and $SIGNKEYID.
* g10/call-agent.c (agent_scd_keypairinfo): Use --keypairinfo.
* sm/call-agent.c (gpgsm_agent_scd_keypairinfo): Ditto.
* scd/app-openpgp.c (do_getattr): Add attributes "$ENCRKEYID" and
"$SIGNKEYID".
* scd/app-piv.c (do_getattr): Ditto.
--

We already have $AUTHKEYID to locate the keyref of the key to be used
with ssh.  It will also be useful to have default keyref for
encryption and signing.  For example, this will allow us to repalce
the use of "OPENPGP.2" by a app type specific keyref.

The OpenPGP card creates keys according to parameters read from a data

scd: Fix flushing of CA-FPR data objects
* 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.

APP_CHANGE_FLAG_CLEAR.

It is specified in the specification version 3.1 or later.  Some

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).

* 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.

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.

Arnaud wrote:

  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.

Commit 91b826a38880fd8a989318585eb502582636ddd8 was not enough to
avoid all sign extension on shift problems.  Hanno Böck found a case
with an invalid read due to this problem.  To fix that once and for
all almost all uses of "<< 24" and "<< 8" are changed by this patch to
use an inline function from host2net.h.

096e7457ec Change all quotes in strings and comments to the new GNU standard.
The asymmetric quotes used by GNU in the past (`...') don't render
nicely on modern systems.  We now use two \x27 characters ('...').

The proper solution would be to use the correct Unicode symmetric
quotes here.  However this has the disadvantage that the system
requires Unicode support.  We don't want that today.  If Unicode is
available a generated po file can be used to output proper quotes.  A
simple sed script like the one used for en@quote is sufficient to
change them.

The changes have been done by applying

  sed -i "s/\`\([^'\`]*\)'/'\1'/g"

to most files and fixing obvious problems by hand.  The msgid strings in
the po files were fixed with a similar command.

37228cfa05 Allow generation of card keys up to 4096 bit.
This patch implementes a chunk mode to pass the key parameters from
scdaemon to gpg.  This allows to pass arbitrary long key paremeters;
it is used for keys larger than 3072 bit.

Note: the card key generation in gpg is currently broken.  The keys
are generated but it is not possible to create the self-signature
because at that time the gpg-agent does not yet know about the new
keys and thus can't divert the sign request to the card.  We either
need to run the learn command right after calling agent_scd_genkey or
implement a way to sign using the currently inserted card.  Another
option would be to get rid of agent_scd_genkey and implement the
feature directly in agent_genkey.
