Daniel Kahn Gillmor 7249ab0f95 common: Avoid unnecessary ambiguity in argparse.
* common/argparse.c (find_long_option): Avoid unnecessary ambiguity.
--

If two struct ARGPARSE_OPTS share a prefix in their long_opt name, but
have the exact same short_opt and flags, they are aliases and not
distinct options.  Avoid reporting this as an ambiguity, so that (for
example) both --clearsign and --clear-sign can be invoked as --clear.

* doc/examples/systemd-user/*.service: Add ExecReload directives to
  indicate the canonical way to reload the services.

GnuPG recommends reloading the agent and dirmngr with "gpgconf
--reload".  if anyone is running them as systemd user services, they
might ask them to reload in the systemd way, so teach systemd the
right thing to do.

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 is a long standing bug.  There are two different things; The
serialization of allocating a new SLOT, and the serialization of using
the SLOT.  The latter was implemented in new_reader_slot by lock_slot.
However, the former was not done.  Thus, there was a possible race where
a same SLOT is allocated to multiple threads.

NIIBE Yutaka c7ec9c4224 scd: Improve internal CCID driver.
* scd/ccid-driver.c (scan_or_find_usb_device): Fix return value.
Support device with multiple CCID interfaces.  Fix the case with
READERNO.  Support partial string match of "reader-port" like PC/SC
driver.

I don't know any device with multiple CCID interfaces, though.

NIIBE Yutaka d26c51825e dirmngr: Fix for --disable-libdns usage.
* dirmngr/dns-stuff.c (enable_recursive_resolver, set_dns_nameserver)
(reload_dns_stuff): Conditionalize with USE_LIBDNS.
(get_h_errno_as_gpg_error): Map HOST_NOT_FOUND to GPG_ERR_NO_NAME.

--

get_dns_srv assumes error code of GPG_ERR_NO_NAME when no SRV record
available.

Neal H. Walfield 1909e994cb tools: Show a clearer error message if a server doesn't support WKS
* tools/gpg-wks-client.c (command_send): If we fail to lookup the
submission address, print a better error message.  If it is because
the corresponding file doesn't exist, provide the hint that the server
probably doesn't support WKS.
