2011-06-15Remove support for Linux 2.2 configuration fallbackDavid Sommerseth1-11/+2
When configuring OpenVPN nowadays, the TUN/TAP configuration can sometimes jump into the Linux 2.2 fallback code paths, which will also fails. The reason it jumps into fallback mode is that the tun/tap device already exists or that /dev/net/tun does not exist. This can be very confusing, as /dev/tunX which the fallback mode tries to use, does not exist on Linux 2.4 and newer. Considering that the last Linux 2.2 update was released 25-Feb-2004 and the first Linux 2.4 release came 04-Jan-2001, there are no reasonable reasons to help users to stay on outdated kernels. I consider this extra code path just waste of bytes ... so lets make the world simpler. Signed-off-by: David Sommerseth <davids@redhat.com> Acked-by: Gert Doering <gert@greenie.muc.de>

2011-05-22Windows IPv6 cleanup - properly remove IPv6 routes and interface configGert Doering1-2/+28
after tunnel shutdown. Needs to make delete_route_ipv6() visible from tun.c (route.c, route.h) and to properly zero-out host bits from IPv6 "network" at interface route clearing. Further, add IPv6 routes with "store=active" to make sure nothing lingers after a system crash while OpenVPN was running. While at it, small Solaris cleanup - use CLEAR() to zero-out "ifr" struct. Tested on Windows XP SP3 and Win7 by Gert Doering and Tony Lim. Signed-off-by: Gert Doering <gert@greenie.muc.de>
2011-05-19Change the netsh.exe command from "add" to "set".smos1-2/+2
This prevents the netsh.exe command from exiting with a status 1 when the address already exists. By adding store=active the address will not survive a reboot and be assigned temporarily.

2011-04-24- Win32 IPv6 ifconfig support, using "netsh" callsGert Doering1-73/+152
- 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

2009-11-19Fixed a client-side bug that occurred when the "dhcp-pre-release"james1-29/+67
or "dhcp-renew" options were combined with "route-gateway dhcp". The problem is that the IP Helper functions for DHCP release and renew are blocking, and so calling them from a single-threaded client stops tunnel traffic forwarding, and hence breaks "route-gateway dhcp" which requires an active tunnel. The fix is to call the IP Helper functions for DHCP release and renew from another process. Version 2.1_rc21b. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@5164 e7ae566f-a301-0410-adde-c780ea21d3b5

2008-08-05Added additional warnings to flag common gotchas:james1-1/+64
* 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:james1-110/+144
* 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
