If the issuer does not provide a DP and the user wants such an issuer,

old behaviour which requires that a suitable LDAP server has been
configured to lookup a CRL by issuer.

There is no need to read the list of options from the components
unless they convey a default value.  It is better to consult only the
list we have in gpgconf-comp.c to decide on whether an option should
be displayed.   Right, this might mess up thing if a newer gpgconf
version is used with an older component, but we already print warnings
in this case and in general we do not want to support this anymore -
the times of gpg 1.4. and 2.0 are long over now.

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.

This is not yet finished but a make check works.  gpg has the most

migration target.  SE-Linux checks and version-ed config files are
missing and will be added later.

This function is intended as a more general version of gpg's
pubkey_string function.  It has the advantage to avoid mallocs and
uses static table of algorithm strings instead.  There should be only
a few dozen of such strings (if at all) and thus all those allocations
we do internally in gpg's pubkey_string and the static buffers all
over the place are not too nice.

This change does away with encrypting and decrypting the cached PIN in

cryptogram and let scdaemon decrypt after retrieving it from the
agent.  This way we do not need to share a key between gpg-agent and
scdaemon and further the cached content is invalid after the scdaemon
process has been replaced.

--

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.

This code as a lot of rough edges, in particular it relies on a well
behaving keyboxd.  We need to add code to shutdown the datastream
reader thread in case of errors and to properly get it up again.  We
also need to make really sure that both threads run in lockstep so
that the datastream thread is only active while we are sending a
command to the keyboxd.

We should also see whether we can depend nPth initialization on the
--use-keyboxd option to avoid any problems with nPth.

And we need to test on Windows.

common: Prepare for parsing mail sub-addresses.
* common/mbox-util.c (mailbox_from_userid): Add arg subaddress and

(main): Call new test and add option --no-sub.
--

Some stats: In the about 5300000 keys on the SKS servers we found 3055
unique mailboxes with a '+' in it.  After removing leading and
trailing '+' as well as multiple '+' (e.g. "c++" or "foo+bar+baz")
2697 were left which seem to be valid sub-addresses.

To filter mailboxes out from a line delimited list with
user-ids (e.g. an SQL output), the command

   t-mbox-util --verbose --filter

can be used; to output w/o sub-addresses add --no-sub.

2b5718c1f7 common/iobuf: optimize iobuf_read_line
* common/iobuf.c (iobuf_read_line): Add fast path for finding '\n'
character in buffer.
--

This patch reduce per byte overhead in iobuf_read_line by avoiding
using iobuf_get when possible and use memchr to find '\n'. This
speeds armored decryption.

Benchmark results below, tested on Intel Core i7-4790K (turbo off).

When gpg was invoked by a Perl web application on FreeBSD, fstat in

lighter than fstat, it works fine.  Since uur purpose is to check if
file descriptor is valid or not, lighter operation is better.

Spawning minimized shows icons in the task bar so users

This actually fixes a couple of cases for Windows.  Both --home-dir

surprising one.  Note that this does not include a full syntax check

--

This fixes a potential overflow if LFs are passed to the status
string functions.  This is actually not the case and would be wrong
because neither the truncating in libassuan or our escaping is not the
Right Thing.  In any case the functions need to be more robust and
comply to the promised interface.  Thus the code has been factored out
to a helper function and N has been bumped up correctly and checked in
all cases.

For some uses this changes the behaviour in the error case (i.e. CR or
LF passed): It will now always be C-escaped and not passed to
libassuan which would truncate the line at the first LF.

I did some test to see whether this has an effect.  A test program

compression.  Single read means the old behaviour, multi read the new
behaviour which fills up the buffer when the read(2) returned only 4k

Originally the KBX code was written to allow standalone use.  However
this required lot of ugliness like separate memory allocators and
such.  It also precludes the use of some standard functions from
common due to their use of the common gnupg malloc functions.
Dropping all that makes things easier.  Minor disadvantages: the kbx
call done for gpg will now use gcry malloc fucntions and not the
standard malloc functions.  This might be a bit slower but removing
them even fixes a possible bug in keybox_tmp_names which is used in
gpg and uses gpg's xfree which is actually gcry_free.

https://lists.gnupg.org/pipermail/gnupg-devel/2017-November/033250.html
for a longer explanation why this is sometimes useful.

build: Do not define logging.h constants for libgpg-error dev versions.
* common/logging.h [GPGRT_LOG_WITH_PREFIX]: Do not define the log
constants.
--

logging.h uses constants we plan to use for future versions of
libgpg-error.  My dev version already has the logging functions and
thus I run into a conflict.  This patch protects against this and make
the GnuPG work with later libgpg-error versions.

It was not the best idea to use constants from a planned libgpg-error
in the first place.  The actual problem are the enums, the macros
won't harm.

Use the gpgrt log functions if possible.
* common/logging.c: Do not build any code if we can use the gpgrt_log
functions.
(log_logv_with_prefix): Rename to log_logv_prefix and change order of
args so that this function matches its printf like counterpart
gpgrt_logv_prefix.  Change all callers.
(log_debug_with_string): Rename to log_debug_string. Change all
callers.
(log_printhex): Move first arg to end so that this function matches
its printf like counterpart gpgrt_log_printhex.  Change all callers.
* common/logging.h: Divert to gpgrt/libgpg-error if we can use the
gpgrt_log functions.
(bug_at): Add inline versions if we can use the gpgrt_log functions.
* configure.ac (GPGRT_ENABLE_LOG_MACROS): Add to AH_BOTTOM.
(mycflags): Add -Wno-format-zero-length.
--

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.

--

Without the rounding we saw in verbose mose

 [...]to come up ... (4s)

immediately without the expected one second delay.  Waiting for the
next seconds did not work if nanosleep was used due to improper passed
parameters in gnupg_usleep.

Adding --debug-wait for dirmngr in daemon mode is required to test
this change.

Prior to 26086b36 the non-existance of the socket directory was

26086b36 we now create the directory on demand, but the function still
returned the fallback path.  This made the agent bind the socket in
the socket directory, and the client trying to connect to the socket
in the home directory.

Note that this does not yet allow to detect compressed data piped to

Our regression test suite makes use of the envvar GNUPG_BUILDDIR.  Now
the code in gnupg for evaluating this envvar is only included in a
development version (that is one with a "-betaNNN" suffix).  For a
real release the envvar is not considered.  However during a "make
distcheck" a "make check" is done for the build directory.  Without
defining that envar we would try to run binaries in the install
directory ("_inst" sub-directory) which are not yet installed at that
time.

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.

If two struct ARGPARSE_OPTS share a prefix in their long_opt name, but

When removing not a simple socket file but the entire directory the
old code missed most events and thus did not worked properly.

IN_DELETE_SELF has also been added to the watch list to detect a
removal of the directory.  However, in all tests that event was not
triggered.  The only way it could be triggered was by not watching
the socket dir but an arbitary directory and rmdir that.

common: Rename an odd named function.
* common/openpgp-oid.c (oid_crv25519): Rename to oid_cv25519.
(openpgp_oid_is_crv25519): Rename to openpgp_oid_is_cv25519.  Change
callers.

--

We use "cv25519" everywhere else and thus the test function should not
have a surprising name.

common: Guarantee that gnupg_get_time does not return an error.
* common/gettime.c (gnupg_get_time): Abor if time() failed.
(gnupg_get_isotime): Remove now useless check.
(make_timestamp): Remove check becuase we already checked this modulo
the faked time thing.
--

In reality a call foo = time (NULL) can never fail because the only
defined error is EFAULT, but we don't provide a buffer.
