2008-09-062.1_rc8 and earlier did implicit shell expansion on scriptjames1-1/+1
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
2008-08-10Fixed build issue with ./configure --disable-socks --disable-http.james1-1/+1
Fixed separate compile errors in options.c and ntlm.c that occur on strict C compilers (such as old versions of gcc) that require that C variable declarations occur at the start of a {} block, not in the middle. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3219 e7ae566f-a301-0410-adde-c780ea21d3b5
2008-08-05Added additional warnings to flag common gotchas:james1-0/+5
* 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
2008-07-27Added additional warnings for:james1-0/+7
* --tls-remote -- some people misunderstand the semantics * --script-security -- warn if script-security will allow user-defined scripts to be called, and also warn separately if passwords may be passed to scripts via the environment git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3129 e7ae566f-a301-0410-adde-c780ea21d3b5
2008-07-26Completely revamped the system for calling external programs and scripts:james1-2/+5
* 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

2008-06-11Updated version to 2.1_rc7e.james1-8/+15
Added client authentication and packet filtering capability to management interface. Extended packet filtering capability to work on both --dev tun and --dev tap tunnels. Updated valgrind-suppress file. Made "Linux ip addr del failed" error nonfatal. Amplified --client-cert-not-required warning. Added #pragma pack to proto.h. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@2991 e7ae566f-a301-0410-adde-c780ea21d3b5
2008-06-04Incremented version to 2.1_rc7d.james1-0/+9
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

2006-11-23Fixed issue where struct env_set methods thatjames1-1/+17
change the value of an existing name=value pair would delay the freeing of the memory held by the previous name=value pair until the underlying client instance object is closed.

2006-04-05I've recently worked on a better version of pkcs11-helper. I've also mergedjames1-2/+3
it into QCA (Qt Cryptographic Architecture), so that KDE 4 will finally be able to use smartcards. The changes allows the following features: 1. Thread safe, is activated if USE_PTHREAD. 2. Slot event - Will allow us in the future to disconnect VPN when smartcard is removed. In order to support this OpenVPN must support threading... At least SIGUSR1 from a different thread. Threading should be supported in both Windows and Linux. -- currently disabled. When I talk about threading support it is just support in configuration script and that the method that SIGUSR1 self can be called from a different thread. I already handle the monitor threads. 3. Certificate enumeration - Will allow us to finally have one configuration file for all users! When you add the plugin GUI stuff you talked about, we will be able to display a list of available certificates for the user to select. -- currently disabled. 4. Data object manipulation - Will allow us to store tls-auth on the smartcard as well. -- currently disabled. 5. Many other minor improvements.
