* Remove ENABLE_SSL define (and --disable-ssl configure option)Steffan Karger2014-12-311-4/+4
| | | | | | | | | | | | | | | | | | | Remove the --disable-ssl configure option and accompanying ENABLE_SSL defines in the master/2.4 branch, to reduce the code and testing complexity a bit. This does not remove to runtime option to run without SSL, just the compile time option to not include any SSL-related code. During the community meeting in November 2014 there were no objections amongst he developers present. Also, this has been announced on the -users and -devel mailing lists two weeks ago, without any response whatsoever.

* plugin: Extend the plug-in v3 API to identify the SSL implementation usedDavid Sommerseth2013-07-031-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OpenVPN would segfault unexpectedly if it would be compiled against PolarSSL and the plug-in would expect OpenSSL, or vice-versa. This segfault would not appear before the plug-in would try to access functions which would be available if the plug-in and OpenVPN uses the same SSL implementation. This patch adds a member to the plug-in initialisation function, which identifies the SSL implementation. The log_v3 plug-in is updated accordingly + a simple fix to make it buildable again using the ./build script. A minor documentation error in the openvpn-plugin.h was also corrected, where it mentioned OPENVPN_PLUGIN_VERSION instead of OPENVPN_PLUGINv3_STRUCTVER. v2 - add const ovpnSSLAPI ssl_api at the end of struct openvpn_plugin_args_open_in and not in the "middle" v3 - fix bug in plug-in init, as the SSLAPI was located wrong in the args struct sent to the openvpn_plugin_open_v3() function. v4 - Ensure SSLAPI got a sane/known value if SSL is disabled or unknown Signed-off-by: David Sommerseth <davids@redhat.com> Acked-by: Gert Doering <gert@greenie.muc.de> Message-Id: <1372879030-10576-1-git-send-email-dazo@users.sourceforge.net> URL: http://article.gmane.org/gmane.network.openvpn.devel/7754 Signed-off-by: Gert Doering <gert@greenie.muc.de>
* Fix parameter listing in non-debug builds at verb 4Josh Cepek2013-03-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | When built with enable_debug=no, the parameter output expected at --verb 4 is not printed due to use of #ifdef ENABLE_DEBUG in the responsible code sections. This appears to be a mistake when looking at the configure help text for enable_small and enable_debug. This change keys the relevant code off of enable_small instead, including the parameter listing when enale_small=no (the configure-script default.) Most of this code is in options.c, with some callers present in plugin.c/h and route.c/h. No function code is changed, just the #ifdef values to use the small feature instead of debug. This means builds no longer need enable_debug=yes in order to get the expected log output at verb 4.

* Fix v3 plugins to support returning values back to OpenVPN.Kenneth Rose2012-10-151-2/+2
| | | | | | | | | | | | | | | | There's a small implementation issue with the V3 plugin API implementation. V3 plugins cannot return data back to OpenVPN using openvpn_plugin_args_func_return since openvpn_plugin_args_func_return.return_list is always NULL. This patch makes the behaviour identical to the V2 API (return_list is again a proper out parameter).

* add API for plug-ins to write to openvpn logHeiko Hund2012-08-061-1/+61
| | | | | | | | | | | | | | Some plugins want to add messages to the openvpn log file. The plugin_log() and plugin_vlog() APIs provide ways for them to do so. OPENVPN_PLUGINv3_STRUCTVER is not incremented as the v3 plugin API is new in 2.3 and this is merged during alpha phase.
