* handle Windows unicode pathsHeiko Hund2012-02-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | Openvpn for Windows is not compiled as a Unicode binary and thus cannot handle paths which contain non-ASCII characters using the argv vector. Characters that are not present in the system codepage are simply replaced with a question mark, e.g. if started as 'openvpn --config домой.ovpn' the file '?????.ovpn' is tried to be opened as configuration. The same applies to paths in config files which need to be UTF-8 encoded if they contain non ASCII characters. The option line 'key лев.pem' will lead to openvpn trying to open 'лев.pem' on a system with codepage 1252. This patch makes openvpn read the command line in UCS-2 and convert it to UTF-8 internally. Windows stores names in the filesystem in UCS-2. When using a paths openvpn converts it from UTF-8 to UCS-2 and uses the wide character Windows API function.

* Fix Microsoft Visual Studio incompatibility in plugin.cDavid Sommerseth2011-08-251-10/+10
| | | | | | | | | | | MS Visual Studio don't like to have struct members named in the variable declaration. Without this fix, Visual Studio is not able to compile the new v3 plug-in API.

* Separate the general plug-in version constant and v3 plug-in structs versionDavid Sommerseth2011-03-251-2/+2
| | | | | | | | | | | | | After a review of the second round of the the v3 plug-in implementation, it was decided to use a separate constant defining the version of the structs used for argument and return value passing, instead of OPENVPN_PLUGIN_VERSION. To not make it too complex, this patch uses a shared version constant for all the v3 structures. It is not expected that these strucutures will change too much and too often.

* Extend the v3 plug-in API to send over X509 certificatesDavid Sommerseth2011-03-251-4/+11
| | | | | | | | | The certificates sent to the plug-in API will only happen during the OPENVPN_PLUGIN_TLS_VERIFY phase and will contain a pointer to the OpenSSL X509 certificate data. Signed-off-by: David Sommerseth <dazo@users.sourceforge.net> Acked-by: James Yonan <james@openvpn.net>

* Merge branch 'feat_misc' into beta2.2David Sommerseth2010-11-181-4/+0
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | Conflicts: acinclude.m4 config-win32.h configure.ac misc.c thread.c thread.h - These conflicts was mainly due to feat_misc getting old and mostly caused by the pthread clean-up patches in feat_misc Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>
| * Clean-up: Remove pthread and mutex locking codeDavid Sommerseth2010-11-141-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code was not activated at all, and hard coded as disabled in syshead.h with this code snippet: /* * Pthread support is currently experimental (and quite unfinished). */ #if 1 /* JYFIXME -- if defined, disable pthread */ #undef USE_PTHREAD #endif So no matter if --enable-pthread when running ./configure or not, this feature was never enabled in reality. Further, by removing the blocker code above made OpenVPN uncompilable in the current state. As the threading part needs to be completely rewritten and pthreading will not be supported in OpenVPN 2.x, removing this code seems most reasonable. In addition, a lot of mutex locking code was also removed, as they were practically NOP functions, due to pthreading being forcefully disabled Signed-off-by: David Sommerseth <dazo@users.sourceforge.net> Acked-by: James Yonan <james@openvpn.net>

* Completely revamped the system for calling external programs and scripts:james2008-07-261-9/+10
| | | | | | | | | | | | | | | | | | | | | | * All external programs and scripts are now called by execve() on unix and CreateProcess on Windows. * The system() function is no longer used. * Argument lists for external programs and scripts are now built by the new argv_printf function which natively outputs to string arrays (i.e. char *argv[] lists), never truncates its output, and eliminates the security issues inherent in formatting and parsing command lines, and dealing with argument quoting. * The --script-security directive has been added to offer policy controls on OpenVPN's execution of external programs and scripts. Also added a new plugin example (openvpn/plugin/examples/log.c) that logs information to stdout for every plugin method called by OpenVPN. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3122 e7ae566f-a301-0410-adde-c780ea21d3b5

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support asynchronous authentication by plugins by allowing OPENVPN_PLUGIN_AUTH_USER_PASS_VERIFY to return OPENVPN_PLUGIN_FUNC_DEFERRED. See comments in openvpn-plugin.h for documentation. Enabled by ENABLE_DEF_AUTH. Added a simple packet filter functionality that can be driven by a plugin. See comments in openvpn-plugin.h for documentation. Enabled by ENABLE_PF. See openvpn/plugin/defer/simple.c for examples of ENABLE_DEF_AUTH and ENABLE_PF. "TLS Error: local/remote TLS keys are out of sync" is no longer a fatal error for TCP-based sessions, since the error can arise normally in the course of deferred authentication. In a related change, allow packet-id sequence to begin at some number n > 0 for TCP sessions, rather than strictly requiring sequence to begin at 1. Added a test to configure.ac for LoadLibrary function on Windows. Modified "make dist" function to include all files from install-win32 so that ./domake-win can be run from a tarball-expanded directory. setenv and setenv-safe directives may now omit a value argument which defaults to "". git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@2978 e7ae566f-a301-0410-adde-c780ea21d3b5
