2011-04-24- Win32 IPv6 ifconfig support, using "netsh" callsGert Doering
- initialize tuntap->ipv6 in init.c::do_init_tun(), to make sure it's setup "early enough", no matter what ifconfig_order() wants - change call convention for open_tun(): drop "ipv6" flag, because it's incompatible with windows/openbsd calling sequence (ifconfig first, open_tun later) - also affects open_tun_generic() and tuncfg(). - drop ipv6_support() helper function - has no useful purpose anymore - introduce add_route_connected_v6_net() helper for Win32, Darwin, Netbsd (cleanup code) - fix NetBSD tunnel setup - destroy/recreate before ifconfig'ing, to make sure no leftover configuration lingers on tunnel from previous call (NetBSD tunnels are always persistent unless explicitely destroyed) - DARWIN (MacOS X) gets its own #ifdef section for open_tun()/close_tun() now, because close_tun() needs to cleanup IPv6 ifconfig

2011-03-25Extend the v3 plug-in API to send over X509 certificatesDavid Sommerseth
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>
2011-03-25Provide 'dev_type' environment variable to plug-ins and script hooksDavid Sommerseth
Normally OpenVPN is configured with --dev {tun,tap}, but it is also possible to use --dev myvpn instead. In these situations, OpenVPN will request --dev-type as well to be able to set up a tun or tap device properly. The 'dev' environment variable will contain the value provided by --dev. In those cases where the plug-in/script need to behave differently when using a tun device versus using a tap device, there are no possibilities for it to know what kind of device --dev myvpn would be. This patch adds a 'dev_type' environment variable which contains a string of the device type, either automatically discovered based on the --dev name, or set using the --dev-type option.

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>
2010-11-14Clean-up: Remove pthread and mutex locking codeDavid Sommerseth
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>

2010-11-12Adding support for SOCKS plain text authenticationPierre Bourdon
This patch adds support for SOCKS plain text (username/password) authentication as described in RFC 1929. It adds an optional third parameter to the socks-proxy option, which is a file containing the login credentials. I've been using this patch for two weeks now and it does not seem to cause any problem. The only modifications are in the SOCKS handshake handling and the options parser.

2010-10-21Revamped the script-security warning logging (version 2)David Sommerseth
The main task of this patch is to avoid reporting the SCRIPT_SECURITY_WARNING over and over again, in addition to not show this warning when it should not be a problem. This general warning should now only appear once, and only when --script-security is not set, 0 or 1. In all other cases this warning should not appear. In addition, this warning will come close to the script-hook which most probably will fail. It will also give a little bit more concrete hint on which script-hook which failed. If --script-security is 2 or 3, only the execve failure itself will be shown. This message will on the other hand be shown repeatedly. This is a new rewritten version which simplifies the implementaion of the new openvpn_run_script() function. It was considered to remove it completely, but due to code clearity and easy of use it was decided to make this function a static inline function instead. Anyhow, this function will enforce openvpn_execve_check() to be called with the S_SCRIPT flag. Patch ACKed on the developers meeting 2009-04-29.

2010-10-21enhance tls-verify possibilityMathieu GIANNECCHINI
It should be nice to enhance tls-verify check possibilities against peer cert during a pending TLS connection like : - OCSP verification - check any X509 extensions of the peer certificate - delta CRL verification - ... This patch add a new "tls-export-cert" option which allow to get peer certificate in PEM format and to store it in an openvpn temporary file. Peer certificate is stored before tls-script execution and deleted after. The name of the related temporary file is available under tls-verify script by an environment variable "peer_cert". The patch was made from OpenVPN svn Beta21 branches. Here is a very simple exemple of Tls-verify script which provide OCSP support to OpenVPN (with tls-export-cert option) without any OpenVPN "core" modification : X509=$2 openssl ocsp \ -issuer /etc/openvpn/ssl.crt/RootCA.pem \ -CAfile /etc/openvpn/ssl.capath/OpenVPNServeur-cafile.pem \ -cert $peer_cert \ -url http://your-ocsp-url if [ $? -ne 0 ] then echo "error : OCSP check failed for ${X509}" | logger -t "tls-verify" exit 1 fi This has been discussed here: <http://thread.gmane.org/gmane.network.openvpn.devel/2492> <http://thread.gmane.org/gmane.network.openvpn.devel/3150> <http://thread.gmane.org/gmane.network.openvpn.devel/3217> This patch has been modified by David Sommerseth, by fixing a few issues which came up to during the code review process.

2009-09-27Eliminated the limitation on the number of options that can be pushedjames
to clients, including routes. Previously, all pushed options needed to fit within a 1024 byte options string. Remember that to make use of this feature to allow many routes to be pushed to clients, the client config file must specify the max-routes option, and the number of pushed routes cannot exceed this limit. Also, both server and client must include this commit. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@4991 e7ae566f-a301-0410-adde-c780ea21d3b5
2009-09-17The maximum number of "route" directives (specified in the configjames
file or pulled from a server) can now be configured via the new "max-routes" directive. Previously, the limit was set to 100 and fixed by a compile-time constant. Now the limit is dynamic and can be modified by the "max-routes" directive. If max-routes is not specified, the default limit is 100. Note that this change does not address the maximum size of the pushed options string sent from server to client, which is still controlled by the TLS_CHANNEL_BUF_SIZE compile-time constant. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@4967 e7ae566f-a301-0410-adde-c780ea21d3b5

2008-09-062.1_rc8 and earlier did implicit shell expansion on scriptjames
arguments since all scripts were called by system(). The security hardening changes made to 2.1_rc9 no longer use system(), but rather use the safer execve or CreateProcess system calls. The security hardening also introduced a backward incompatibility with 2.1_rc8 and earlier in that script parameters were no longer shell-expanded, so for example: client-connect "docc CLIENT-CONNECT" would fail to work because execve would try to execute a script called "docc CLIENT-CONNECT" instead of "docc" with "CLIENT-CONNECT" as the first argument. This patch fixes the issue, bringing the script argument semantics back to pre 2.1_rc9 behavior in order to preserve backward compatibility while still using execve or CreateProcess to execute the script/executable. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3311 e7ae566f-a301-0410-adde-c780ea21d3b5

* Warn when ethernet bridging that the IP address of the bridge adapter is probably not the same address that the LAN adapter was set to previously. * When running as a server, warn if the LAN network address is the all-popular 192.168.[0|1].x, since this condition commonly leads to subnet conflicts down the road. * Primarily on the client, check for subnet conflicts between the local LAN and the VPN subnet. Added a 'netmask' parameter to get_default_gateway, to return the netmask of the adapter containing the default gateway. Only implemented on Windows so far. Other platforms will return 255.255.255.0. Currently the netmask information is only used to warn about subnet conflicts. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3179 e7ae566f-a301-0410-adde-c780ea21d3b5

2008-07-26Completely revamped the system for calling external programs and scripts:james
* 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

2008-06-04Incremented version to 2.1_rc7d.james
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
