* 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.

* 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.

scheme.

The new variables features makes it easier to write AD queries without
requiring domain specific expressions.
(cherry picked from commit 207c99567c)
* 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/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.

* dirmngr/dirmngr.h (opt): Add ignored_crl_extensions.
* dirmngr/crlcache.c (crl_cache_insert): Implement option.

* dirmngr/ks-engine-ldap.c (PAGE_SIZE): New.
(struct ks_engine_ldap_local_s): Add several new fields.
(ks_ldap_clear_state): Release them.
(search_and_parse): Factored out from ks_ldap_get and extended to
support the paged mode.
(ks_ldap_get): Implement the pages mode for --first and --next.
* dirmngr/server.c (cmd_ks_get): Provide a dummy passphrase in --first
mode.
* dirmngr/Makefile.am (dirmngr_LDADD): Add LBER_LIBS.
--
The paged mode allows to retrieve more items than the servers usually
limit (e.g. 1000 for an LDS). This patch also allows to use --first
without a patter to retrieve all keyblocks (except for disabled and
revoked keys).

This feature allows to fetch keyblock by keyblock from an LDAP server.
This way tools can process and maybe filter each keyblock in a more
flexible way. Here is an example where two keyblocks for one mail
address are returned:
$ gpg-connect-agent --dirmngr
> ks_get --ldap --first <foo@example.org>
[... First keyblock is returned ]
OK
> ks_get --next
[ ... Next keyblock is returned ]
OK
> ks_get --next

* dirmngr/ldapserver.c (ldapserver_parse_one): Turn LINE into a const.
Use strtokenize instead of strtok style parsing.

This fixes a problem with resulted in a General Error for the second

LDAP_OPT_AREC_EXCLUSIVE. It is ignored on other systems.

* dirmngr/crlcache.c (crl_cache_reload_crl): Rework the double loop.
Remove the unused issuername_uri stuff.
--
It is quite common that LDAP servers are blocked and thuis the HTTP
access point should be used instead. This worked well for
certificates where the DP are given in this form:
crlDP: ldap://x500.bund.de/[...]
http://x500.bund.de/[...]
issuer: none
but it failed for this form
crlDP: ldap://x500.bund.de/[...]
issuer: none
crlDP: http://x500.bund.de/[...]
issuer: none
because the LAST_ERR thing terminated the outer loop. This pacth
fixes this and also cleans up the code to be more robust.
Note that the common workaround of using --ignore-ldap-dp will now
only be needed if the firewall uses packet dropping instead of proper
ICMP rejects.
* dirmngr/certcache.c (put_cert): When PERMANENT, reject the
certificate which is obviously invalid.
--
With this change, invalid certificates from system won't be registered
into cache. Then, an intermediate certificate which is issued by an
entity certified by such an invalid certificate will be also rejected
with GPG_ERR_INV_CERT_OBJ. With less invalid certificates in cache,
it helps the validate_cert_chain function work better.
