* sm/certchain.c (find_up_search_by_keyid): Consider all matching
certificates.
(find_up): Add some debug messages.
--
The DFN-Verein recently re-issued its CA certificates without
generating new keys. Thus looking up the chain using the authority
keyids works but may use still existing old certificates. This may
break the CRL lookup in the Dirmngr. The hack to fix this is by using
the latest issued certificate with the same subject key identifier.
As usual Peter Gutman's X.509 style guide has some comments on that
re-issuing.

Resolved conflicts:
sm/certchain.c - whitespace fixes.
* g10/getkey.c (get_user_id): Do not call xmalloc with 0.
* common/xmalloc.c (xmalloc, xcalloc): Take extra precaution not to
pass 0 to the arguments.
--
The problem did not occur in 1.x because over there the xmalloc makes
sure to allocate at least one byte. With 2.x for most calls the
xmalloc of Libgcrypt is used and Libgcrypt returns an error insteead
of silent allocating a byte. Thus gpg 2.x bailed out with an
"Fatal: out of core while allocating 0 bytes".
The extra code in xmalloc.c is for more robustness for the other
xmalloc calls.

Note that GUIs may use the gpg status line

(pubkey_get_nskey): Ditto.
(pubkey_get_nsig): Ditto.
(pubkey_get_nenc): Ditto.
(pubkey_nbits): Take care of RSA_E and RSA_S.
--
The problem was that parse_key did not know about RSA_S and thus used
an opaque MPI which later crashed Libgcrypt. It is possible to fix
that also in Libgcrypt but we better do it here as well.
A test key using RSA_S is 0x98EEB6F7D87171CF.

--
This feature can be used to return the session key for just a part of
a file. For example to downloading just the first 32k of a huge file,
decrypting that incomplete part and while ignoring all the errors
break out the session key. The session key may then be used on the
server to decrypt the entire file without the need to have the private
key on the server.

This slightly changes the semantics of most commands in that they

not make sense to create a trustdb if there is no need for it.

Due to recent changes to adjust for use with Libgcrypt 1.6, "gpg
--version" printed two question marks. This patches fixes that and
also make sure that gpg does advertise any ECC features. The patch in
build_list is not really needed.

(pubkey_get_nenc): Return 0 for ECC algorithms.
--
Libgcrypt 1.6 features algorithm 18 (generic ECC). Because of the
missing mapping and no real support for the OpenPGP ECC format, this
led to parsing errors of ECC packets. We better better explicitly
tell gpg that we ECC is not supported.

--
By modifying a keyserver or a DNS record to send a secret key, an
attacker could trick a user into signing using a different key and
user id. The trust model should protect against such rogue keys but
we better make sure that secret keys are never received from remote
sources.

* include/cipher.h (PUBKEY_USAGE_NONE): New.
* g10/getkey.c (parse_key_usage): Set new flag.
--
We do not want to use the default capabilities (derived from the
algorithm) if any key flags are given in a signature. Thus if key
flags are used in any way, the default key capabilities are never
used.
This allows to create a key with key flags set to all zero so it can't
be used. This better reflects common sense.

This is a more general fix for the nested compression packet bug. In

compression filters onto an iobuf stream. This patch also reduces the
number of error messages for the non-import case.

* configure.ac (NEED_GPG_ERROR_VERSION): Set to 1.11.
* common/util.h: Remove GPG_ERR_ replacements.

The replacement macros actually never worked because gog-error.h uses
enums and not macros. libgpg-error 1.11 is 6 months old and thus it
should not be a problem to require that version.
Future replacement macros may then use the new
GPG_ERROR_VERSION_NUMBER to detect missing error codes.

gniibe reported this to gnupg-devel on 2012-07-04:
[...]
(2) UPDATESTARTUPTTY doesn't work to switch TTY for pinentry for
SSH.
[...]
Current implementation:
In the function start_command_handler_ssh, the logic puts
priority on ctrl->session_env which is initialized by
agent_init_default_ctrl. There are always GPG_TTY and TERM
defined, because lines around 968 in gpg-agent.c, it says:
/* Make sure that we have a default ttyname. */
While UPDATESTARTUPTTY updates opt.startup_env, it doesn't
affect at all.
Here is a patch to point the issue. Tested and works for me.
