This is is the second part to support the new Key Block subpacket.
The idea is that after having received a signed mail, it is instantly
possible to reply encrypted - without the need for any centralized
infrastructure.
There is one case where this does not work: A signed mail is received
using a specified signer ID (e.g. using gpg --sender option) and the
key block with only that user ID is thus imported. The next time a
mail is received using the same key but with a different user ID; the
signatures checks out using the key imported the last time. However,
the new user id is not imported. Now when trying to reply to that
last mail, no key will be found. We need to see whether we can update
a key in such a case.

This patch adds support for a to be proposed OpenPGP ferature:
Introduce the Key Block subpacket to align OpenPGP with CMS.
This new subpacket may be used similar to the CertificateSet of
CMS (RFC-5652) and thus allows to start encrypted communication
after having received a signed message. In practice a stripped down
version of the key should be including having only the key material
and the self-signatures which are really useful and shall be used by
the recipient to reply encrypted.
#### Key Block
(1 octet with value 0, N octets of key data)
This subpacket MAY be used to convey key data along with a signature
of class 0x00, 0x01, or 0x02. It MUST contain the key used to create
the signature; either as the primary key or as a subkey. The key
SHOULD contain a primary or subkey capable of encryption and the
entire key must be a valid OpenPGP key including at least one User ID
packet and the corresponding self-signatures.
Implementations MUST ignore this subpacket if the first octet does not
have a value of zero or if the key data does not represent a valid
transferable public key.

* configure.ac (SAFE_VERSION, SAFE_VERSION_DOT)
(SAFE_VERSION_DASH): Remove.
--
Die to the switch to the new option parser, the permissions were not
anymore checked. This patch fixes this. Note that there there is no
checking for the global config file because that file is not expected
to be user modifiable.
This patch also adds checking against the list of SE-linux secured
files. However, like in the old code the checking does not work in
practise because the to be checked files are added to the the list
only after option parsing. Tested using temporary debug code.
The SAFE_VERSION macros were used for RISC OS, which is not anymore
supported, and only in the now removed get_default_configname. There
purpose was that a RISC OS could use a modified config.h here.

--
Key generation direct from the card used to work for all cards except
the OpenPGP cards. The key generation from card using an OpenPGP card
is special because the fingerprint is stored on the card and we must
make sure that the newly created key has the same fingerprint. This
requires that we take the key creation date as stored on the card into
account.
Along with the recent change in gpg-agent this change also fixes a
problem with existing stub files.
Note that with a key take from a card the self-signature are created
with the current time and not the creation time. This allows to
better distinguish keys created using the same card.

This allows to first create keys on the card (e.g. using gpg-card)
even without having any public key for OpenPGP. Then the key
generation option 14 (cardkey) can be used to create a primary OpenPGP
key from the key on the card.
There are still a couple of problems related to the agent which
creates the stub key and may run into problems if creating a second
key from the card. This will be fixed in a future patch.

It seems to be possible to play tricks with packet structures so that

return code and let the main driver in gpg call log_error, we can fix
this case.
Note that using gpg --verify-files and relying solely on gpg's return

This function is intended as a more general version of gpg's

uses static table of algorithm strings instead. There should be only

we do internally in gpg's pubkey_string and the static buffers all

--
It turned out that using the hash of the entire blob was not helpful.
Thus we redefine the Unique-Blob-ID (UBID) as the primary fingerprint
of the blob. In case this is a v5 OpenPGP key a left truncated
version of the SHA-256 hash is used; in all other cases the full SHA-1
hash. Using a SHA-256 hash does not make sense because v4 keys are
and will for some time be the majority of keys and thus padding them
with zeroes won't make any difference. Even if fingerprint collisions
can eventually be created we will assume that the keys are bogus and
that it does not make sense to store its twin also in our key storage.
We can also easily extend the update code to detect a collision and
reject the update.

parameter which defaults to 400ms. This works on my Windows-10

The Web Key Directory should carry only one key. However, some

This patch puts a limit on 5 on it (we had none right now) and also
fixes the issue that gpg could not work immediately with the requested
key because the code uses the fingerprint of the key to use the
imported key. Now the first key is used. On a second try (w/o
accessing the WKD) the regular key selection mechanism would be in
effect. I think this is the most conservative approach. Let's see

When importing an invalid secret key ring for example without key
binding signatures or no UIDs, gpg used to let gpg-agent store the
secret keys anyway. This is clearly a bug because the diagnostics
before claimed that for example the subkeys have been skipped.
Importing the secret key parameters then anyway is surprising in
particular because a gpg -k does not show the key. After importing
the public key the secret keys suddenly showed up.
This changes the behaviour of

A little drawback of that code is that if the WKD has no update for an
expired key each access of the key will trigger a WKD lookup (unless
cached by the dirmngr). To avoid this we need to record the last time
we have checked for an update but that would in turn require that we
update the keyring for each check. We defer this until we have a
better key database which allows for fast updates of meta data.
Testing the code is currently a bit cumbersome because it requires to
update a key in the WKD several times. Eventually we we need a
network emulation layer to provide sample data for the regression
tests.

* g10/key-check.c (sig_comparison): Take care of HELP_COUNTER.
(key_check_all_keysigs): De-duplicate on a per-block base.
--
The key_check_all_keysigs first does a detection of duplicate
signature. This is done over all signatures at once. The problem
here is for example:
key
uid_1
sig_uid_1.1
sig_uid_1.2
subkey_1
sig_sub_1.1
subkey_2
sig_sub_2.1
sig_sub_2.2 (duplicate of sig_sub_1.1)
Now the de-duplication deletes the first signature and keeps the
second. That works in most cases for foreign signature on userids but
in the above constellation the code simply removes sig_sub_1.1 so that
subkey_1 has no binding signature anymore. In a later step during
import the missing binding is detected and subkey_1 is removed because
it is not anymore valid. The sig_sub_2.2 will also be removed later
because it does not check out for subkey_2 (that is as expected).
The fix is to let the de-duplication work only on blocks (ie. within
the signatures of a user id or a subkey). This will not detect all
duplicates but that does not harm because later steps will detect and
remove them.
In the above case (with this patch applied) the second phase of
key_check_all_keysigs will reorder key signatures and move the
duplicate sig_sub_2.2 directly after sig_sub_1.1. This duplicates the
signature and for cleanness we should kick the de-duplication process
again. This will be done with a followup patch.

This fixes an actual regression in GPGME where FAILURE is considered

fail and not just record that that a signature could not be verified.
In particular for files with more than one signature a log_error if
often called to show that a pubkey is missing for one of the
signatures. Using that log_error is correct in that case.
