f5782e11a5 dirmngr: Avoid warnings during non-ntbtls build.
* dirmngr/t-http.c (my_http_tls_verify_cb): Avoid warnings when not
using ntbtls.

Without this patch, when building without ntbtls, we see the following
warnings during "make check":

Note that this changes the way the standard cert is used: We require
that it is installed at /usr/share/gnupg and we do not allow to change
it.  If this is not desired, the the standard cert can be removed or
replaced by a newer one.

libdns: Hack to skip negation term.
* dirmngr/dns.c (dns_nssconf_loadfile): Skip negation terms in
nsswitch.conf parser.
--

This small patch was submitted along with this comment:

  We've been having issues over at Arch Linux with the new libdns
  code.  Our /etc/nsswitch.conf contains the following line:

    hosts: files mymachines resolve [!UNAVAIL=return] dns myhostname

  And it turns out dirmngr fails to parse the negation statement (the
  bang in !UNAVAIL). This results in gnupg not being able to resolve
  any name.

  Looking at dirmngr/dns.c it was unclear to me how to properly handle
  such negations. The dns_anyconf_scan calls used in
  dns_nssconf_loadfile do not allow to store a negation bit easily...

  In the meantime, I wrote the attached patch which ignores those
  statements altogether. It makes libdns work as expected for us.

ChangeLog entry by wk.

This fixed the problem:

  Short version: macOS doesn't include /etc/nsswitch.conf and GnuPG's
  dirmngr is hard-erroring when that file is missing, such that no DNS
  operations succeed and --recv-key returns ENOENT type errors to the
  caller.

Libassuan always uses 127.0.0.1 to connect to the local Tor proxy.

the connect call in Libassuan fails when it tries to connect to a v6

It would be cleaner to have the my_sock_new_for_addr function as a
public interface in Libassuan; for now we need to duplicate some code.

dirmngr: Implement experimental SRV record lookup for WKD.
* dirmngr/server.c (cmd_wkd_get): Support SRV records.
--

This patch changes the way a WKD query is done.  Now we first look for
a SRV record for service "openpgpkey" and port "tcp" under the
to-be-queried domain.  If such a record was found and the target host
matches the to-be-queried domain or is a suffix to that domain, that
target host is used instead of the domain name.  The SRV record also
allows to change the port and obviously can be used for
load-balancing.

For example a query for the submission address of example.org with the
SRV record specification

_openpgpkey._tcp        IN     SRV   0 0  0    wkd.foo.org.
                        IN     SRV   0 0  0    wkd.example.net.
                        IN     SRV   0 0  4711 wkd.example.org.

(queried using the name "_openpgpkey._tcp.example.org") would fetch
from this URL:

 https://wkd.example.org:4711/.well-known/openpgpkey/submission-address

Note that the first two SRV records won't be used because foo.org and
example.net do not match example.org.  We require that the target host
is identical to the domain or be a subdomain of it.  This is so that
an attacker modifying the SRV records needs to setup a server in a
sub-domain of the actual domain and can't use an arbitrary domain.
Whether this is a sufficient requirement is not clear and needs
further discussion.

This option allows for runtime switching to the system's standard

optional resolver libraries (as of now ADNS).  Note that on Windows
there is no code to use systems's resolver and thus for full
functionality dirmngr must be build with a separate resolver.

This patch also does way with configure options to disable the use of
CERT and SRV records.

Before we need it.
* dirmngr/ldap-wrapper.c (ldap_wrapper): Call
ldap_wrapper_launch_thread() just in time (before any attempt to use
an ldap subprocess).

--

A dirmngr process that never looks anything up in LDAP has no need for
a reaper thread, but one was started automatically.  This thread wakes
up every two seconds to look for ldap processes that might never have
been running.  We won't start more than one reaper thread for any
given dirmngr due to the static int "done" in
ldap_wrapper_launch_thread(), so it's safe to call this every time
there is a use of ldap_wrapper.

If someone wants to do further dirmngr optimizations for ldap users,
the reaper thread itself could use dynamically-calculated timeouts
(and probably needs to be alerted dynamically when a new ldap
subprocess is available so it can re-calculate those timeouts).

Note: It's not clear to me how to test ldap access effectively; i know
of no public ldap services that i can verify against, and i do not run
my own ldap servers.  If someone has a publicly-available ldap server
that developers can run tests against, i would be happy to hear about
it.

Given that the timer tick is only used for housekeeping tasks and

The minor drawback is tha the housekeeping may be delayed by one
minute.

set from w32_service_control().  shutdown_pending is now never
assigned outside of handle_signal() or within an inotify test, neither
of which are available on w32.

Consider three possible classes of dirmngr configuration:

 b) hkps:// keyserver URLs, but no hkp-cacert directives

 c) hkps:// keyserver URLs, and at least one hkp-cacert directive

class (a) provides no confidentiality of requests.

class (b) currently will never work because the server certificate
cannot be validated.

class (c) is currently supported as intended.

This patch allows users with configurations in class (b) to work as
most users expect (relying on the system certificate authorities),
without affecting users in classes (a) or (c).

--

Without this changeset, the condition of the filesystem when dirmngr
is initialized will have an effect on later activities of dirmngr.

For example, if a file identified by a hkp-cacert directive doesn't
exist when dirmngr starts, dirmngr will behave as though it simply
didn't have the hkp-cacert directive set at all, even if the file
should appear later.

dirmngr currently behaves differently if no hkp-cacert directives have
been set then it does when at least one hkp-cacert directive has been
set.  For example, its choice of CA cert for
hkps://hkps.pool.sks-keyservers.net depends on whether a TLS CA file
has been registered.  That behavior shouldn't additionally depend on
the state of the filesystem at the time of dirmngr launch.

In standard English, the normal construction is "${XXX} allows ${YYY}
to" -- that is, the subject (${XXX}) of the sentence is allowing the
object (${YYY}) to do something.  When the object is missing, the
phrasing sounds awkward, even if the object is implied by context.
There's almost always a better construction that isn't as awkward.

These changes should make the language a bit clearer.

pre-2.1 made sure that the 0x prefix was put before the fingerprint so
