agent: Make --allow-loopback-pinentry the default.
* agent/gpg-agent.c (oNoAllowLoopbackPinentry): New.
(opts): Add --no-allow-loopback-pinentry.  Hide
description of --allow-loopback-pinentry.
(parse_rereadable_options): Set opt.allow_loopback_pinentry by
default.
(main): Replace allow-loopback-pinentry by no-allow-loopback-pinentry
in the gpgconf list.
* tools/gpgconf-comp.c (gc_options_gpg_agent): Ditto.
--

Given that a user can anyway change that options in the gpg-agent.conf
file and that gpg needs to be invoked with --pinentry-mode=loopback
the former default does not make much sense - in that option is useful
at all.  There was a discussion of this topic on gnupg-devel in April
without a clear result.  So we try this new default and just in case
real problems are found for the majority of installations, we can
revert that.  The new default is also aligned with GnuPG's policy to
make its use easier and only require users with very high security
standards to tweak certain options (those users have anyway modeled
their threat model and configured their software according to this).

GnuPG 2.3+ will use a new format to store private keys that is both
more flexible and easier to read and edit by human beings.  The new
format stores name,value-pairs using the common mail and http header
convention.

This patch adds the parser and support code and prepares GnuPG 2.1 for
the new format.

agent: Fix regression due to recent commit 4159567.
* agent/protect.c (do_encryption): Fix CBC hashing.
--

The buggy code included an extra closing parenthesis before
the (protected-at) term in the CBC hashing.  We now do it by
explicitly hashing the protected stuff and append the rest of the
expression instead of a fixed closing parenthesis.  Note that the OCB
hashing only differs that it does no include the protected part.

Instead of using the old OpenPGP way of appending a hash of the
plaintext and encrypt that along with the plaintext, the new scheme
uses a proper authenticated encryption mode.  See keyformat.txt for a
description.  Libgcrypt 1.7 is required.

This mode is not yet enabled because there would be no way to return
to an older GnuPG version.  To test the new scheme use
gpg-protect-tool:

 ./gpg-protect-tool -av -P abc -p --debug-use-ocb <plain.key >prot.key
 ./gpg-protect-tool -av -P abc -u <prot.key

Any key from the private key storage should work.

This is a first step to support certificate via the agent.  The only

certificate.  Note that ssh-add sends the private key anyway first and
only then follows with the certificate+private key.

What we need to implement next is a way to store the certificate in
the agent and return it on request.

a (sig)bus PC/VAX hacker bugs.

Instead of trying to fix the alignment, it is better to use a second
calloc for the second struct.

bba74cdd95 Fix pinentry loopback and passphrase contraints.
* agent/command.c (cmd_get_passphrase): Don't repeat passphrase for
pinentry loopback mode.
* agent/genkey.c (check_passphrase_constraints): Immediately return when
pinentry mode is loopback.

--
Fixes endless loop when inquiring a passphrase with
pinentry-mode=loopback that may not satisfy passphrase contraints.

* agent/cvt-openpgp.c (get_keygrip, convert_secret_key)
(convert_transfer_key): CURVE is the name of curve.

e5891a82c3 Curve25519 support.
* 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.

Replace GNUPG_GCC_A_ macros by GPGRT_ATTR_ macros.
* 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.

agent: Unset INSIDE_EMACS on gpg-agent startup
* agent/gpg-agent.c (main): Unset INSIDE_EMACS envvar.

--

The variable is set only temporarily when gpg is called from Emacs,
keeping it during the session makes no sense.

i18n_localegettext.  Expand LunderscorePROTO.
* agent/genkey.c (check_passphrase_constraints): Use xtryasprintf
again to keep the old translations.
