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.

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

the connect call in Libassuan fails when it tries to connect to a v6
address using a v4 socket.
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/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.

Due to our switch to Libdns getsrv didn't worked correctly because it

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

--
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.

class (a) provides no confidentiality of requests.
class (b) currently will never work because the server certificate

class (c) is currently supported as intended.
This patch allows users with configurations in class (b) to work as

--
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.

* dirmngr/dirmngr.c (main): Add new --supervised command, which is a
mode designed for running under a process supervision system like
systemd or runit.
* doc/dirmngr.texi: document --supervised option.
--
"dirmngr --supervised" is a way to invoke dirmngr such that a system
supervisor like systemd can provide socket-activated startup, log
management, and scheduled shutdown.
When running in this mode, dirmngr:
* Does not open its own listening socket; rather, it expects to be
given a listening socket on file descriptor 3.
* Does not detach from the invoking process, staying in the
foreground instead.

A better would be to use a linked list and avoid these large arrays.

I assumed that the log_fd also has a reader object but that reader

The real bug with the non-released ldap_wrapper control objects was
that when looping over distribution points we did not closed the used

gnulib has always been a cause of trouble in GnuPG because we used
only a very few functions and the complex include machinery of gnulib
is quite complex and the cause for many build problems for example on
OS X. This is not gnulib's fault but due to our limited use of gnulib
and that we only rarely update the gnulib code to avoid regressions.
In part two we will address the functions
mkdtemp
setenv
unsetenv
strpbrk

* dirmngr/crlfetch.c (!USE_LDAP): Ditto.
Signed-off-by: Werner Koch <wk@gnupg.org>
* dirmngr/Makefile.am: Avoid $(DNSLIBS) for dirmngr_ldap
* g10/Makefile.am: $(LIBREADLINE) is only for gpg2; gpgv2 does not
need $(LIBASSUAN_LIBS)
* sm/Makefile.am: gpgsm does not need $(ZLIBS)
* tools/Makefile.am: gpgconf does not need $(NPTH_LIBS)

In the course of building GnuPG 2.1.0 beta864 on debian, i found that
several of the installed executables were linked to libraries that
they did not need to be linked to, which would cause unnecessary
package dependencies at runtime.
The changeset here removes these unnecessary libraries from linking.
Something similar could possibly also be done by passing --as-needed
to the linker, but trimming the depenencies seems more parsimonious.
* configure.ac (NEED_NTBTLS_ABI, NEED_NTBTLS_VERSION): New.
(HTTP_USE_NTBTLS): New. Prefer over GNUTLS.
* m4/ntbtls.m4: New.
* m4/Makefile.am (EXTRA_DIST): Add new file.
* common/http.c: Add conditionals to eventually use NTBTLS.
--
This is only the configure stuff. If you have NTBTLS installed GNUTLS
will not be used but there won't be any https support either :-(.
This patch is used to have a real world test bench for the forthcoming
library.
* dirmngr/ks-engine-hkp.c (cert_log_cb): Move to ...
* dirmngr/misc.c (cert_log_cb): here.
* dirmngr/ks-engine-http.c (ks_http_fetch): Support 307-redirection
and https.
--
Note that this requires that the root certificates are registered using
the --hkp-cacert option. Eventually we may introduce a separate
option to allow using different CAs for KS_FETCH and keyserver based
requests.
* dirmngr/ks-engine-hkp.c (hostinfo_s): Add fields cname, v4addr, and
v6addr.
(create_new_hostinfo): Clear them.
(my_getnameinfo): Add args numeric and r_isnumeric.
(is_ip_address): New.
(map_host): Add arg r_host. Rewrite the code to handle pools in a
special way.
(ks_hkp_print_hosttable): Change format of help info output.
(make_host_part): Add arg optional r_httphost.
(send_request): Add arg httphost.
(ks_hkp_search, ks_hkp_get, ks_hkp_put): Get httphost and pass it to
send_request.
--
This changes quite some things on how the hostinfo is maintained.
However, it might be better to rework the data structures and have one
entry per IP address instead of this clumsy patch.
* common/http.c (http_open): Add arg httphost.
(http_open_document): Pass NULL for httphost.
(send_request): Add arg httphost. If given, use HTTPHOST instead of
SERVER. Use https with a proxy if requested.
(http_verify_server_credentials): Do not stop at the first error
message.
* dirmngr/ocsp.c (do_ocsp_request): Adjust call to http_open.
* keyserver/curl-shim.c (curl_easy_perform): Ditto.
* dirmngr/ks-engine-http.c (ks_http_fetch): Ditto.
* dirmngr/ks-engine-hkp.c (ks_hkp_help): Ditto.
* common/Makefile.am ($(PROGRAMS)): New rule
(t_http_LDADD): Use libcommontls.a without directory prefix.
* dirmngr/Makefile.am ($(PROGRAMS)): New rule.
* common/mischelp.h (JNLIB_GCC_HAVE_PUSH_PRAGMA): New.
* dirmngr/dirmngr.c (handle_tick): Factor time check out to ...
(time_for_housekeeping_p): new.
--
I am not sure whether that y2038 hack is really useful but it might
make me smile in my retirement.
* dirmngr/dirmngr.c (HOUSEKEEPING_INTERVAL): New.
(housekeeping_thread): New.
(handle_tick): Call new function.
* dirmngr/ks-engine-hkp.c (RESURRECT_INTERVAL): New.
(struct hostinfo_s): Add field died_at and set it along with the dead
flag.
(ks_hkp_print_hosttable): Print that info.
(ks_hkp_housekeeping): New.
--
The resurrection gives the host a chance to get back to life the next
time a new host is selected.
* dirmngr/ks-engine-hkp.c (ks_hkp_get): Allow exact search mode.
* g10/keyserver.c (keyserver_import_name): Implement.
(keyserver_get): Use exact mode for name based import.
(keyserver_get): Add args R_FPR and R_FPRLEN. Change all callers.
* dirmngr/ks-engine-hkp.c (ks_hkp_search, ks_hkp_get): Print SOURCE
status lines.
* g10/call-dirmngr.c (ks_status_parm_s): New.
(ks_search_parm_s): Add field stparm.
(ks_status_cb): New.
(ks_search_data_cb): Send source to the data callback.
(gpg_dirmngr_ks_search): Change callback prototope to include the
SPECIAL arg. Adjust all users. Use ks_status_cb.
(gpg_dirmngr_ks_get): Add arg r_source and use ks_status_cb.
* g10/keyserver.c (search_line_handler): Adjust callback and print
"data source" disgnostic.
(keyserver_get): Print data source diagnostic.
--
It has often been requested that the actually used IP of a keyservers
is shown in with gpg --recv-key and --search-key. This is helpful if
the keyserver is actually a pool of keyservers. This patch does this.
* dirmngr/ks-action.c (ks_action_resolve): Rename var for clarity.
(ks_action_search, ks_action_put): Ditto.
(ks_action_get): Consult only the first server which retruned some
data.
* dirmngr/ks-engine-hkp.c (SEND_REQUEST_RETRIES): New.
(map_host): Add arg CTRL and call dirmngr_tick.
(make_host_part): Add arg CTRL.
(mark_host_dead): Allow the use of an URL.
(handle_send_request_error): New.
(ks_hkp_search, ks_hkp_get, ks_hkp_put): Mark host dead and retry on
error.
* dirmngr/server.c (cmd_killdirmngr): Factor some code out to ...
(check_owner_permission): here.
(cmd_keyserver): Add options --dead and --alive.
* dirmngr/ks-engine-hkp.c (host_in_pool_p): New.
(ks_hkp_mark_host): New.
--
Also removed the warning that the widnows part has not yet been done.
AFAICS, the current mingw supports the all used socket functions.
* dirmngr/cdblib.c (cdb_init) [W32]: Remove unused var.
* dirmngr/dirmngr-client.c (start_dirmngr): s/int/assuan_fd_t/.
* dirmngr/dirmngr.c (w32_service_control): Mark unused args.
(call_real_main): New.
(main) [W32]: Use new function to match prototype.
(real_main) [W32]: Mark unused vars.
(handle_signal) [W32]: Do not build the function at all.
(handle_connections) [W32]: Do not define signo.
* dirmngr/ldap-wrapper-ce.c (outstream_reader_cb): Remove used vars.
* g10/tdbio.c (ftruncate) [DOSISH]: Define only if not yet defined.
* dirmngr/ldap-url.c (ldap_utf8_strtok): Remove unused r3d arg.
(ldap_str2charray): Remove lasts.
--
I have no clue why an utf8 version was planned to be used. Do the
LDAP folks really assume that eventually non-ascii delimiters might be
used? Simplified it to silence the warning about an used helper var.
Replace hardwired strings at many places with new macros from config.h
and use the new strusage macro replacement feature.
* common/asshelp.c (lock_spawning) [W32]: Change the names of the spawn
sentinels.
* agent/command.c (cmd_import_key): Use asprintf to create the prompt.
The asymmetric quotes used by GNU in the past (`...') don't render
nicely on modern systems. We now use two \x27 characters ('...').
The proper solution would be to use the correct Unicode symmetric
quotes here. However this has the disadvantage that the system
requires Unicode support. We don't want that today. If Unicode is
available a generated po file can be used to output proper quotes. A
simple sed script like the one used for en@quote is sufficient to
change them.
The changes have been done by applying
sed -i "s/\`\([^'\`]*\)'/'\1'/g"
to most files and fixing obvious problems by hand. The msgid strings in
the po files were fixed with a similar command.
GnuPG requires that options are given before other arguments. This
can sometimes be confusing. We now print a warning if we found an
argument looking alike a long option without being preceded by the
stop option. This is bug#1343.
* common/argparse.h (ARGPARSE_FLAG_STOP_SEEN): New.
* common/argparse.c (arg_parse): Set new flag.
* g10/gpg.c (main): Print the warning.
* agent/gpg-agent.c (main): Ditto.
* dirmngr/dirmngr.c (main): Ditto.
* g13/g13.c (main): Ditto.
* scd/scdaemon.c (main): Ditto.
* sm/gpgsm.c (main): Ditto.
* tools/gpg-connect-agent.c (main): Ditto.
* tools/gpgconf.c (main): Ditto.
For the shared code parts it is cumbersome to pass an error sourse
variable to each function. Its value is always a constant for a given
binary and thus a global variable makes things a lot easier than the
former macro stuff.
* common/init.c (default_errsource): New global var.
(init_common_subsystems): Rename to _init_common_subsystems. Set
DEFAULT_ERRSOURCE.
* common/init.h: Assert value of GPG_ERR_SOURCE_DEFAULT.
(init_common_subsystems): New macro.
* common/util.h (default_errsource): Add declaration.
* kbx/keybox-defs.h: Add some GPG_ERR_SOURCE_DEFAULT trickery.
* agent/gpg-agent.c (get_agent_ssh_socket_name): Use
INVALID_HANDLE_VALUE instead of 0.
(handle_signal) [!HAVE_W32_SYSTEM]: Don't define.
(handle_connections): Port Windows code to NPTH.
* dirmngr/dirmngr.c (handle_connections): Port Windows code to NPTH.
* g13/g13.c (handle_connections): Port Windows code to NPTH.
* scd/scdaemon.c (handle_connections): Port Windows code to NPTH.
* agent/gpg-agent.c, dirmngr/dirmngr.c, g13/g13.c, scd/scdaemon.c
(USE_GCRY_THREAD_CBS): New macro, defined if
GCRY_THREAD_OPTION_VERSION is 0.
(fixed_gcry_pth_init) [!USE_GCRY_THREAD_CBS]: Don't define.
(main) [!USE_GCRY_THREAD_CBS]: Do not install thread callbacks.
* scripts/gitlog-to-changelog: New script. Taken from gnulib.
* scripts/git-log-fix: New file.
* scripts/git-log-footer: New file.
* doc/HACKING: Describe the ChangeLog policy
* ChangeLog: New file.
* Makefile.am (EXTRA_DIST): Add new files.
(gen-ChangeLog): New.
(dist-hook): Run gen-ChangeLog.
Rename all ChangeLog files to ChangeLog-2011.
We had some debug code here which prevented it from working.
The host selection code still needs a review!
* ks-engine-http.c (ks_http_help): Do not print help for hkp.
* ks-engine-hkp.c (ks_hkp_help): Print help only for hkp.
(send_request): Remove test code.
(map_host): Use xtrymalloc.
* certcache.c (classify_pattern): Remove unused variable and make
explicit substring search work.
Since 2009-12-08 gpg was not able to find email addresses indicated
by a leading '<'. This happened when I merged the user id
classification code of gpgsm and gpg.
To better cope with round robin pooled A records like keys.gnupg.net
we need to keep some information on unresponsive hosts etc. What we
do now is to resolve the hostnames, remember them and select a random
one. If a host is dead it will be marked and a different one
selected. This is intended to solve the problem of long timeouts due
to unresponsive hosts.
The code is not yet finished but selection works.
The import test imports the keys as needed and because they are
passphrase protected we now need a pinentry script to convey the
passphrase to gpg-agent.
The basic network code from http.c is used for finger. This keeps the
network related code at one place and we are able to use the somewhat
matured code form http.c. Unfortunately I had to enhance the http
code for more robustness and probably introduced new bugs.
Test this code using
gpg --fetch-key finger:wk@g10code.com
(I might be the last user of finger ;-)
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
Similar to gpg-agent, dirmngr's wait timeouts are now synced to the
full second. Increased ldap helper thread timeout to 2 seconds.
Nuked some white spaces.
Changed order of some conditional to make to put the special case into
the true branch. Indentation changes. Minor other changes to make the
ECC code more similar to the rest of our code.
It builds but many sefltests still fail. Need to fix that before
using it with an ECDH enabled libgcrypt.

2011-01-21 Werner Koch <wk@g10code.com>
* configure.ac: Need Libgcrypt 1.4.6 due to AESWRAP.
(HAVE_GCRY_PK_ECDH): Add new test.
[agent/]
2011-01-21 Werner Koch <wk@g10code.com>
* cvt-openpgp.c (GCRY_PK_ECDH) [!HAVE_GCRY_PK_ECDH]: New.
[include/]
2011-01-21 Werner Koch <wk@g10code.com>
* cipher.h (GCRY_PK_USAGE_CERT): Remove compatibility macros
because we now require libgcrypt 1.4.6.
(GCRY_PK_ECDH): Add replacement.
The following works:
gpg2 --gen-key (ECC)
gpg2 --list-keys
gpg2 --list-packets ~/.gnupg/pubring.gpg
gpg2 --list-packets <private key from http://sites.google.com/site/brainhub/pgpecckeys>
ECDH doesn't work yet as the code must be re-written to adjust for gpg-agent refactoring.
