* dirmngr/http.c (run_proxy_connect): Don't set keep_alive, since it
causes resource leak of FP_WRITE.
Don't try to read response body to fix the hang.

* dirmngr/http.c (enum auth_negotiate_states): New.
(struct proxy_info_s): Add new fields.
(release_proxy_info): Free Windows stuff.
(proxy_get_token): New. Implemented only for Windows for now.
(run_proxy_connect): Add support for auth method Negotiation.
(store_header): Keep some header lines separate.
--
The code does something but I have not yet been able to test it due
to problems setting up Squid with AD authentication. As of now it
will respond with a failure but that should not be worse than not to
implement Negotiation.
Supporting Negotiation using GSS for Unix should eventually also be
done.
GnuPG-bug-id: 6719
* dirmngr/http.c (cookie_s): Add fields pending, up_to_empty_line,
last_was_lf, and last_was_lfcr.
(http_context_s): Add field keep-alive.
(http_wait_response): Set up_to_empty_line. Take care of keep_alive
flag.
(coookie_read): Implement detection of empty lines.
(cookie_write): Free the pending buffer.
--
The problem we fix here is that we already buffered stuff beyond the
empty line which marks the start of the content-length counting. Thus
we tried to wait for more bytes despite that everything had already
been read. This bug might have showed up more often in the real world
since the we changed the BUFSIZ on Windows from 512 byte to 8k. It
also depends on the length of the headers and whether the server
closed the connection so that we ignored the Content-Length.
The bug was introduced earlier than 2010 and could have the effect
that a connection got stuck until the network layer timed out.
Note that the keep-alive parts of the patch are not yet used.
* dirmngr/http.c: Remove gnutls version specific code.
(send_request): Factor some code out to ...
(run_proxy_connect): new.
(mk_proxy_request): new.
(mk_std_request): new.
* configure.ac (NEED_GNUTLS_VERSION): Require 3.2.
--
This patch is to factor out some code and also to remove support for
legacy gnutls versions. Note that gnutls 3.2 was released 10 years
ago.
* configure.ac (NEED_NTBTLS_VERSION): Require at least 0.2.0 so that
we can remove a conditional compilation.
* dirmngr/http.c (struct proxy_info_s): New.
(release_proxy_info): New to keep proxy information in one object.
(send_request): Factor some code out to ...
(get_proxy_for_url): this,
(send_request_basic_checks): this,
(send_request_set_sni): this,
(run_ntbtls_handshake): this,
(run_gnutls_handshake): and this.
--
Note that this also removes some never used code. For example the
NTBTLS handshake has code taken from GNUTLS which was never used due
to the different ways on how the certificates are checked.
The proxy code has been factored out to make to prepare further
authentication methods. The proxy_info_t was introduced for the same
reason.
Tested against gnutls and ntbtls builds. No proxy tests yet done,
because we need more sophisticated tests anyway.

* dirmngr/server.c (cmd_keyserver): Ignore also hkps://none.
(ensure_keyserver): Better ignore also "none" with a hkp or hpks
scheme.

GnuPG-bug-id: 6708
* common/asshelp.h (ASSHELP_FLAG_AUTOSTART): New.
* common/asshelp.c (start_new_service): Rename arg autostart to flags
and adjust checks.
(start_new_gpg_agent): Likewise. Change all callers.
(start_new_keyboxd): Likewise. Change all callers.
(start_new_dirmngr): Likewise. Change all callers.
--
It is easier to have a generic flags arg instead of adding more and
more dedicated args. verbose and debug are kept as they are because
they are not boolean.
* dirmngr/ldap-misc.c (rfc4517toisotime): Correct index.
--
Obviously the parser assumes the standard ISO format with the 'T'
before the hour. That is not correct here. We need this parser for
the modifyTimestamp thingy.
* dirmngr/dirmngr.c (gpgrt_opt_t): Use string for oFakedSystemTime.
(oFakedSystemTime): Use similar conversion as gpgsm has.
* dirmngr/dirmngr.texi (faked-system-time): Document it.
--
For testing X509 certificates this is usually required and
then confusing that the example from the gpgsm man page
does not work for dirmngr.
* dirmngr/dirmngr.c (gpgrt_opt_t): Use string for oFakedSystemTime.
(oFakedSystemTime): Use similar conversion as gpgsm has.
* dirmngr/dirmngr.texi (faked-system-time): Document it.
--
For testing X509 certificates this is usually required and
then confusing that the example from the gpgsm man page
does not work for dirmngr.
* dirmngr/dirmngr.c (oIgnoreCRLExtension): New.
(opts): Add --ignore-crl-extension.
(parse_rereadable_options): Add to list/
* dirmngr/dirmngr.h (opt): Add ignored_crl_extensions.
* dirmngr/crlcache.c (crl_cache_insert): Implement option.
--
This option is is useful for debugging problems with new CRL
extensions. It is similar to --ignore-cert-extension.
GnuPG-bug-id: 6545
* sm/call-dirmngr.c (run_command_inq_cb): Support SENDCERT_SKI.
* dirmngr/crlcache.c (crl_cache_insert): Print the CRL name along with
the unknown OID nortice.
* dirmngr/http.h (struct http_redir_info_s): Add restrict_redir.
* dirmngr/ks-engine-hkp.c (send_request): Set it depending on flags.
* dirmngr/ks-engine-http.c (ks_http_fetch): Ditto.
* dirmngr/t-http-basic.c (test_http_prepare_redirect): Always set it.
* dirmngr/http.c (http_prepare_redirect): Remove location rewriting
unless the flag is set.
--
GnuPG-bug-id: 6477
* dirmngr/server.c (cmd_ad_query): Add options --help and --subst.
(cmd_getinfo): Add sub-command "sid".
* dirmngr/ks-engine.h (KS_GET_FLAG_SUBST): New.
* dirmngr/ks-engine-ldap.c (ks_ldap_help_variables): New.
(getval_for_filter): New.
(map_rid_to_dn): New.
(ks_ldap_query): Support variables.
--
The new variables features makes it easier to write AD queries without
requiring domain specific expressions.
* dirmngr/server.c (cmd_ks_get): Add option --newer.
(cmd_ad_query): Ditto.
* dirmngr/ldap-misc.c (isotime2rfc4517): New.
(rfc4517toisotime): New.
* dirmngr/ks-action.c (ks_action_get): Add arg newer and pass on.
(ks_action_query): Ditto.
* dirmngr/ks-engine-ldap.c (extract_keys): Print new "chg" record.
(ks_ldap_get): Add arg newer. Modify filter with newer arg.
(ks_ldap_search): Print the modifyTimestamp.
(ks_ldap_query): Add arg newer. Modify filter with newer arg.
--
Note that the modifyTimestamp is also available on Windows, where its
value is more commonly known as whenChanged. Both are constructed
attributes.
Note that the --newer option is a bit of a misnomer because LDAP has
only a greater-or-equal and no greater-than operator.
