* dirmngr/dirmngr.h (opt): Add field "use_tor". * dirmngr/dirmngr.c (oUseTor): New. (opts): Add --use-tor. (parse_rereadable_options): Set option. (main): Tell gpgconf about that option. * dirmngr/crlfetch.c (crl_fetch): Pass TOR flag to the http module and return an error if LDAP is used in TOR mode. (ca_cert_fetch): Return an error in TOR mode. (start_cert_fetch): Ditto. * dirmngr/ks-engine-finger.c (ks_finger_fetch): Pass TOR flag to the http module. * dirmngr/ks-engine-hkp.c (send_request): Ditto. * dirmngr/ks-engine-http.c (ks_http_fetch): Ditto. * dirmngr/ks-engine-ldap.c (ks_ldap_get): Return an error in TOR mode. (ks_ldap_search): Ditto. (ks_ldap_put): Ditto. * dirmngr/ocsp.c (do_ocsp_request): Ditto. Also pass TOR flag to the http module. * dirmngr/server.c (option_handler): Add "honor-keyserver-url-used". (cmd_dns_cert): Return an error in TOR mode. (cmd_getinfo): Add subcommand "tor" * tools/gpgconf-comp.c (gc_options_dirmngr): Add TOR group. -- More work is required to actually make --use-tor useful. For now it returns an error for almost all network access but as soon as we have added the TOR feature to the http module some parts will start to work. Signed-off-by: Werner Koch <wk@gnupg.org>
