The idea here is to unify our use of URLS or colon delimited ldap
keyserver specification. The requirement for percent escaping, for
example the bindname in an URLs, is cumbersome and prone to errors.
This we allow our classic colon delimited format as an alternative.
That format makes it also easy to specify flags to tell dirmngr
whether to use starttls or ldap-over-tls. The code is nearly 100%
compatible to existing specification. There is one ambiguity if the
hostname for CRL/X509 searches is just "ldap"; this can be solved by
prefixing it with "ldap:" (already implemented in gpgsm).

detect this here and use the v4 fingerprint format to convert
it to a key id.

Regarding the freeing of values: I was not able to find a
specification stating it is okay to pass NULL to ldap_value_free, thus
the new wrapper. Also add robustness measures in case ldap_get_value

* dirmngr/ks-engine-ldap.c (keyspec_to_ldap_filter): Ignore revoked

The LDAP schema has a revoked and a disabled flag. The former will be

keys with these LDAP attributes set. This allows to better maintain a
directory with multiple keys per mailbox.

--
This change makes it easy to start working with gnupg: Just insert the
smartcard or token provided to you and the first time you sign a
message the public key associated with the current card will be
imported and everything is set without any configuration.
This works only with an LDAP directory because it can be expected that
the public key has been put into the LDAP during card personalization.
Of course an LDAP server needs to be configured; in a Windows AD
domain this can be a mere "keyserver ldap:///" in dirmngr.conf. Other
configured keyservers are ignored.
Requirements for the card driver: The $SIGNKEYID attribute must exists
and a query for the KEY-FPR attribute needs to return the OpenPGP
fingerprint for that key. This is currently supported for OpenPGP
cards and certain PKCS#15 cards.

The pgpSignerID has no use in the LDAP and thus don't store it.
David's idea back in 2004 was
/* This bit is really for the benefit of people who
store their keys in LDAP servers. It makes it easy
to do queries for things like "all keys signed by
Isabella". */
See-commit: 3ddd4410ae
I consider this dangerous because such a query is not able to validate
the signature, does not get revocation signatures, and also has no
information about the validity of the signatures. Further many keys
are spammed tehse days with faked signatures and it does not make
sense to blow up the LDAP with such garbage.

There is no need to read the list of options from the components

There was no way to specify an LDAPS server in

patch fixes this. Eventually we should allow to replace host and port
by a partial URI in the same way ldap_initialize does it. For backward
compatibility we do not yet do that.
Although the dirmngr code accepts an URL (eg. taken from a
certificate), I can't see how the scheme was ever used. Thus the
patch also detects an ldaps scheme and uses this. That part has not
been tested, though.

We append the raw non-canonicalized local address part to the hash.
Servers who serve the requests from static files will ignore the

database ignore the parameter. The general idea is that service
providers may use their own canonicalization rules. The problem is
that we currently filter the returned key for the full mail address
and thus we will never see a key if the service did a different
canonicalization than we. So consider this to be an experiment.

* dirmngr/ks-engine-hkp.c (select_random_host): Use atomic pass
through the host table instead of risking out-of-bounds write.
--
Multiple threads may write to hosttable[x]->dead while
select_random_host() is running. For example, a housekeeping thread
might clear the ->dead bit on some entries, or another connection to
dirmngr might manually mark a host as alive.
If one or more hosts are resurrected between the two loops over a
given table in select_random_host(), then the allocation of tbl might
not be large enough, resulting in a write past the end of tbl on the
second loop.
This change collapses the two loops into a single loop to avoid this
discrepancy: each host's "dead" bit is now only checked once.
As Werner points out, this isn't currently strictly necessary, since
npth will not switch threads unless a blocking system call is made,
and no blocking system call is made in these two loops.
However, in a subsequent change in this series, we will call a
function in this loop, and that function may sometimes write(2), or
call other functions, which may themselves block. Keeping this as a
single-pass loop avoids the need to keep track of what might block and
what might not.

The old code simply did not use https for downloading of CRLS.
Instead it rewrote https to http under the assumption that the CRL

provided by TLS. These days we should not use any unencrypted content
and thus this patch.

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.

This finalizes the feature to efficiently cache WKD checks. If a

This check tests whether the server responsible for the queried
address has WKD at all enabled. The test is done by checking whether
the "policy" file exists. We do not check the "submission-address"
file because that is not necessary for the web key operation. The
policy file is now required.

useless queries for domains which do not support WKD. The missing
part is a background task to check whether a queried domain supports
WKD at all and to expire old entries.

(cherry picked from commit 65038e6852)
* 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.

* dirmngr/crlcache.c: Clearly document that this fucntions takes
ownership of MD.
(abort_sig_check): Allow NULL for MD.
(crl_parse_insert): Immediately set MD to NULL. Remove check for md
before a calling abort_sig_check.

* common/asshelp.c (wait_for_sock): Round SECSLEFT.
* dirmngr/dirmngr.c (main): Take care of --debug-wait also in dameon
mode.
* common/sysutils.c (gnupg_usleep) [HAVE_NANOSLEEP]: Fix nanosleep use.
--
Without the rounding we saw in verbose mose
[...]to come up ... (5s)
[...]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.

This finalizes the feature to efficiently cache WKD checks. If a
standard WKD query returns no data, we queue a test to be run after
the end of the session (so that we do not delay the calling client).
This check tests whether the server responsible for the queried
address has WKD at all enabled. The test is done by checking whether
the "policy" file exists. We do not check the "submission-address"
file because that is not necessary for the web key operation. The
policy file is now required.
