* http: Improve diagnostic messages.Werner Koch2014-12-081-9/+32
| | | | | | | | | | | | | * common/http.c (send_request): Print TLS alert info (connect_server): Detect bogus DNS entry. -- 1. Prints the TLS alert description. 2. Detect case where the DNS returns an IP address but the server is not reachable at this address. This may happen for a server which is reachable only at IPv6 but but the local machine has no full IPv6 configuration.
* w32: Fix http access module.Werner Koch2014-11-071-8/+25
| | | | | | | * common/http.c (write_server) [W32]: Rework to use send() instead of write even when build with npth. (cookie_read) [W32]: Rework to use recv() instead of read even when build with npth.
* First changes for future use of NTBTLS.Werner Koch2014-10-021-28/+94
| | | | | | | | | | | | | | * 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: Fix the ks_fetch command for the http scheme.Werner Koch2014-09-101-3/+8
| | | | | | | | | | * common/http.c (http_session_ref): Allow for NULL arg. -- We always test for a an existing session and thus passing NULL as session object should be allowed. Reported-by: Jens Lechtenboerger
* Switch to the libgpg-error provided estream.Werner Koch2014-08-261-2/+2
| | | | | | | | | | * configure.ac (NEED_GPG_ERROR_VERSION): Reguire 1.14. (GPGRT_ENABLE_ES_MACROS): Define. (estream_INIT): Remove. * m4/estream.m4: Remove. * common/estream-printf.c, common/estream-printf.h: Remove. * common/estream.c, common/estream.h: Remove. * common/init.c (_init_common_subsystems): Call gpgrt initialization.
* http: Print human readable GNUTLS status.Werner Koch2014-06-131-1/+27
| | | | | * common/http.c (send_gnutls_bye): Take care of EAGAIN et al. (http_verify_server_credentials): Print a human readable status.
* http: Add callback to help logging of server certificates.Werner Koch2014-05-191-20/+33
| | | | | | * common/http.c (http_session_s): Add field cert_log_cb. (http_session_set_log_cb): New. (http_verify_server_credentials): Call callback.

| | | | | | | | | | | | | * 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.
* http: Add reference counting to the session object.Werner Koch2014-05-051-40/+80
| | | | | | | | | | | | | | | | | * common/http.c (http_session_t): Add field "refcount". (_my_socket_new, _my_socket_ref, _my_socket_unref): Add debug code. (send_request, my_npth_read, my_npth_write): Use SOCK object for the transport ptr. (http_session_release): Factor all code out to ... (session_unref): here. Deref SOCK. (http_session_new): Init refcount and transport ptr. (http_session_ref): New. Ref and unref all assignments. -- Having the reference counted session objects makes it easier for the application to pass around only an estream. Without that the application would need to implement an es_onclose machinery for the session object.
* http: Add HTTP_FLAG_FORCE_TLS and http_get_tls_info.Werner Koch2014-05-021-31/+75
| | | | | | | | | | | * common/http.c (http_parse_uri): Factor code out to ... (parse_uri): here. Add arg FORCE_TLS. (do_parse_uri): Ditto. Implement flag. (http_get_tls_info): New.

(make_header_line): Fix bug using int* instead of char*. (http_register_tls_callback): New. (http_register_tls_ca): New. (http_session_new): New. (http_session_release): New. (http_get_header_names): New. (escape_data): Add hack to escape in forms mode. (send_request) [HTTP_USE_GNUTLS]: Support SNI. (send_request) [HTTP_USE_GNUTLS]: Fix use of make_header_line. (send_gnutls_bye): New. (cookie_close): Make use of preclose feature. (http_verify_server_credentials): New. (main) [TEST]: Remove test code. * common/t-http.c: New. * common/tls-ca.pem: New. * common/Makefile.am (tls_sources): New. Move http code to here. (libcommontls_a_SOURCES): New. (libcommontlsnpth_a_SOURCES): New. (EXTRA_DIST): Add tls-ca.pem (module_maint_tests): Add t-http.

| | | | | | | | | | | | | | | | | * configure.ac (HAVE_NPTH): New ac_define. * common/estream.c: Use USE_NPTH instead of HAVE_NPTH. * common/http.c: Ditto. Replace remaining calls to pth by npth calls. (connect_server): Remove useless _(). * common/exechelp-posix.c, common/exechelp-w32.c * common/exechelp-w32ce.c: Use HAVE_PTH to include npth.h. * common/init.c (_init_common_subsystems): Remove call to pth_init. * common/sysutils.c (gnupg_sleep): Use npth_sleep. * scd/ccid-driver.c (my_sleep): Ditto. -- USE_NPTH is used in case were we may build with and without nPth. The missing definition HAVE_NPTH didn't allowed us to build outher sources with nPTh support.
* dirmngr: Make use of IPv4 and IPV6 more explicit.Werner Koch2014-03-141-2/+6
| | | | | | | | | * common/http.c (connect_server): Handle the new flags. * common/http.h (HTTP_FLAG_IGNORE_IPv4, HTTP_FLAG_IGNORE_IPv4): New. * dirmngr/ks-engine-hkp.c (map_host): Add arg r_httpflags.

* Change all quotes in strings and comments to the new GNU standard.Werner Koch2012-06-051-9/+9
| | | | | | | | | | | | | | | | | | | 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.
* Change license for some files in common to LGPLv3+/GPLv2+.Werner Koch2012-04-201-5/+15
| | | | | | | | | | | | | | | | | | | | | | | Having the LGPL on the common GnuPG code helps to share code between GnuPG and related projects (like GPGME and Libassuan).

| | | | | | | | | | | | | | | | | | | | | * configure.ac: Don't check for PTH but for NPTH. (AH_BOTTOM): Remove PTH_SYSCALL_SOFT. (have_pth): Rename to ... (have_npth): ... this. (USE_GNU_NPTH): Rename to ... (USE_GNU_PTH): ... this. * m4/npth.m4: New file. * agent/Makefile.am, agent/cache.c, agent/call-pinentry.c, agent/call-scd.c, agent/findkey.c, agent/gpg-agent.c, agent/trustlist.c, common/Makefile.am, common/estream.c, common/exechelp-posix.c, common/exechelp-w32.c, common/exechelp-w32ce.c, common/http.c, common/init.c, common/sysutils.c, dirmngr/Makefile.am, dirmngr/crlfetch.c, dirmngr/dirmngr.c, dirmngr/dirmngr_ldap.c, dirmngr/ldap-wrapper-ce.c, dirmngr/ldap-wrapper.c, dirmngr/ldap.c, g13/Makefile.am, g13/call-gpg.c, g13/g13.c, g13/runner.c, scd/Makefile.am, scd/apdu.c, scd/app.c, scd/ccid-driver.c, scd/command.c, scd/scdaemon.c, tools/Makefile.am: Port to npth.
* Add finger support to dirmngr.Werner Koch2011-02-081-69/+290
| | | | | | | | | | | | | 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:[email protected] (I might be the last user of finger ;-)
* Nuked almost all trailing white space.post-nuke-of-trailing-wsWerner Koch2011-02-041-40/+40
| | | | | | | | 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.

(http_document): And here. * gpgkeys_hkp.c (srv_replace): New function to transform a SRV hostname to a real hostname. (main): Call it from here for the HAVE_LIBCURL case (without libcurl is handled via the curl-shim). * curl-shim.h, curl-shim.c (curl_easy_setopt, curl_easy_perform): Add a CURLOPT_SRVTAG_GPG_HACK (passed through the the http engine).

| | | | | | | * http.c (do_parse_uri): Remove the hkp port 11371 detection. We implement hkp in the keyserver handler, and the support here makes it appear like a bad hkp request actually succeeded.
