gpg: default-preference-list: prefer SHA512.
* g10/keygen.c (keygen_set_std_prefs): when producing default internal
personal-digest-preferences, keep the same order.  When publishing
external preferences, state preference for SHA512 first.

--

SHA-512 has a wider security margin than SHA-256.  It is also slightly
faster on most of the architectures on which GnuPG runs today.  New
keys should publish defaults that indicate we prefer the stronger,
more performant digest.

Specifically, this changes --default-preference-list from:

   SHA256 SHA384 SHA512 SHA224

to:

   SHA512 SHA384 SHA256 SHA224

This patch deliberately avoids touching --personal-digest-preferences
(which itself would affect the default of --digest-algo and
--cert-digest-algo), so that public-facing cleartext signatures and
identity certifications will continue to be made with SHA256 by
default.

0d0b9eb0d4 g10: Fix regexp sanitization.
* g10/trustdb.c (sanitize_regexp): Only escape operators.

--

Backport from master commit:
	ccf3ba92087e79abdeaa0208795829b431c6f201

To sanitize a regular expression, quoting by backslash should be only
done for defined characters.  POSIX defines 12 characters including
dot and backslash.

Quoting other characters is wrong, in two ways; It may build an
operator like: \b, \s, \w when using GNU library.  Case ignored match
doesn't work, because quoting lower letter means literally and no
much to upper letter.

This actually does not harm because we merely display a buffer
allocated by ourselves.  However, we better tell Valgrind about it so
that we don't need to track this thing down ever again.

  echo cb 0a 75 ff 59 ae 90 d5  74 65 73 74 | \

g10: Simplify "factory-reset" procedure.
* g10/card-util.c (factory_reset): Simplify.

--

In this summer, I got report about old code before this change didn't
work with newer Yubikey.  I got another report test version of OpenPGP
card V3.3 implementation didn't work, either.  Then, I confirmed that
according to the OpenPGP card specification, the procedure of old code
is not expected by its author.

This change simplify "factory-reset" as simple.

Only versions of Gnuk 1.2.2, 1.2.3, 1.2.4, won't work with this
change.  That's because the factory-reset feature of Gnuk was
introduced by reading the implementation of GnuPG, instead of reading
the specification.  Gnuk 1.2.5 and later works well.  All OpenPGPcard
implementations I have work well (2.0, 2.1, 2.2, test version of 3).

We try to verify the primary key and thus seed the passphrase cache
before generating the subkey.  However, the verification does not yet
work for on-card keys and thus the PASSWD --verify send to the agent
returns an error.  This patch detects this error and continues without
a seeded passphrase cache.  After all that pre-seeding is just a
convenience.

The same could happen with other options taking keyids but we won't

* doc/gpg.texi: document this change.
--

This is a partial reversion of
7e1fe791d188b078398bf83c9af992cb1bd2a4b3.  Werner and i discussed it
earlier today, and came to the conclusion that:

 * the risk of metadata leakage represented by a default
   --auto-key-retrieve, both in e-mail (as a "web bug") and in other
   contexts where GnuPG is used to verified signatures, is quite high.

 * the advantages of --auto-key-retrieve (in terms of signature
   verification) can sometimes be achieved in other ways, such as when
   a signed message includes a copy of its own key.

 * when those other ways are not useful, a graphical, user-facing
   application can still offer the user the opportunity to choose to
   fetch the key; or it can apply its own policy about when to set
   --auto-key-retrieve, without needing to affect the defaults.

Note that --auto-key-retrieve is specifically about signature
verification.  Decisions about how and whether to look up a key during
message encryption are governed by --auto-key-locate.  This change
does not touch the --auto-key-locate default of "local,wkd".  The user
deliberately asking gpg to encrypt to an e-mail address is a different
scenario than having an incoming e-mail trigger a potentially unique
network request.

--

The idea here is that the owner of the key created a non-compliant key
and later receives a mail encrypted to that key.  The sender should
have checked this key too but we can't guarantee that.  By hard
failing here the owner of the key will notice that he had created a
non-compliant key and thus has a chance to generate a new compliant
key.  In case the compliant criteria changes and the owner wants to
decrypt an old message he can still switch gpg to another compliant
mode.

gpg: Fix error handling.
* g10/keygen.c (generate_subkeypair): Handle errors from pinentry.
--

Previously, when generating a subkey, gpg would ask for the passphrase
of the primary key.  If that dialog is canceled, gpg would ask a
second time for a passphrase to protect the new subkey.

Fix this by handling the error.

gpg,gpgsm: Fix compliance check for DSA and avoid an assert.
* common/compliance.c (gnupg_pk_is_compliant): Swap P and Q for DSA
check.  Explicitly check for allowed ECC algos.
(gnupg_pk_is_allowed): Swap P and Q for DSA check.
* g10/mainproc.c (proc_encrypted): Simplify SYMKEYS check.  Replace
assert by debug message.

--

Note that in mainproc.c SYMKEYS is unsigned and thus a greater than 0
condition is surprising because it leads to the assumption SYMKEYS
could be negative.  Better use a boolean test.

The assert could have lead to a regression for no good reason.  Not
being compliant is better than breaking existing users.

--
This created a big regression for Windows because the keyring
is only released after the global ctrl is released. So if an operation
does a getkey and then tries to modify the keyring it will fail on
Windows with a sharing violation. We need to modify all
keyring write operations to also take the ctrl and close the
cached_getkey_kdb handle to make writing work. See:

The defaults for gpg and dirmngr are good.  Both programs should work
fine for the simple case without any config file.  The skeleton config
files were being copied at first use (when the defaults are fine).
But when the user needs to fiddle with them (after they've become
sophisticated users), they're likely out of date because gpg has been
upgraded since then.  So they're used for documentation, but they're
stale documentation, which is probably worse than a clean empty file.

--

This patch introduced the framework to store meta data for keys and
user ids in the keyrings/keyboxes.  Ring trust packets are
implementation defined and have always been used in gpg to cache the
signature verification status.

Ring trust packets are only exported with the export option "backup"
and only imported with the import option "restore".

The new code uses a cleaner way to handle the ring trust packets: When
the parser reads a ring trust packet and the previously read packet
matches the type of that ring trust packet, the information is stored
in that previously read packet (signature, user id, or primary key)
and the next packet is read immediately.  Thus only the parser sees
the ring trust packets.  Ring trust packets are written by using the
new function build_packet_and_meta instead of build_packet.  That
function writes a ring trust packet when the needed information is
available.

As a side-effect of this patch the signature status cache works again
and "gpg --check-sigs" is thus much faster.

Back in the old days we did not used the export options for secret
keys export because of a lot of duplicated code and that the old
secring.gpg was anyway smaller that the pubring.gpg.  With 2.1 it was
pretty easy to enable it.

Consider a situation where the user passes "--status-fd 3" but file
descriptor 3 is not open.

During the course of executing the rest of the commands, it's possible
that gpg itself will open some files, and file descriptor 3 will get
allocated.

In this situation, the status information will be appended directly to
whatever file happens to have landed on fd 3 (the trustdb? the
keyring?).

This is a potential data destruction issue for all writable file
descriptor options:

   --status-fd
   --attribute-fd
   --logger-fd

It's also a potential issue for readable file descriptor options, but
the risk is merely weird behavior, and not data corruption:

   --override-session-key-fd
   --passphrase-fd
   --command-fd

Fixes this by checking whether the fd is valid early on before using
it.

gpg: Fix aliases --list-key, --list-sig, and --check-sig.
* g10/gpg.c (opts): Define commands with ARGPARSE_c
instead of ARGPARSE_s_n.

--

These three entries are commands, but they're being treated as a
string-based option for some reason.  However, if you try to use them
concurrently with another command like --clearsign, you'll get "gpg:
conflicting commands".

Furthermore, because they're marked as options, their flags differ
from the commands that they alias, they cause ambiguity in
abbreviation (e.g. try "gpg --list-ke") which should have been fixed
by 7249ab0f95d1f6cb8ee61eefedc79801bb56398f.

Marking them explicitly as commands for argparse should be more
accurate and should resolve the abbreviation ambiguity issue.

According to SUSv3:

  If the subject sequence is empty or does not have the expected form,
  no conversion is performed
  ...
  If no conversion could be performed, 0 is returned and errno may be
  set to [EINVAL].

  http://pubs.opengroup.org/onlinepubs/007908799/xsh/strtol.html

It appears that MacOS X sets errno to EINVAL, but glibc doesn't.
Hence, we map NULL to 0 explicitly.
