* Fixes for the plugin system:Adriaan de Jong2011-10-221-4/+4
| | | | | | | | | - Removed the dependency on an SSL library for USE_SSL when creating non-SSL plugins - Fixed example plugin code to include USE_SSL when needed Signed-off-by: Adriaan de Jong <dejong@fox-it.com> Acked-by: James Yonan <james@openvpn.net> Signed-off-by: David Sommerseth <davids@redhat.com>
* New feauture: Add --stale-routes-checkDavide Guerri2011-09-301-0/+46
| | | | | | | | | | | | | | | | | | This patch adds a stale-routes-check option that takes 2 parameters: a ageing time (in seconds) and a check interval (in seconds). The latter defaults to the former if it's not present. Internally, a new "check" is added in multi_process_per_second_timers_dowork(). This check deletes stale routes and it is inspired to the function multi_reap_range(). We're running a very large connectivity infrastructure based on openVPN (more than 4000 different clients connected per day per server), so we can throughly check this patch (or, of course, any variant of it).

* USE_PF_INET6 by default for v2.3JuanJo Ciarlante2011-08-251-14/+0
| | | | | | | | | | | | | | | | | - put all #ifdef'd code in place, kill the cpp symbol, - thus in v2.3 it's not actually possible to --disable-ipv6 :) RATIONALE: #1 some wacky compilers choke on #ifdef'd constructions for concatenated strings, and given that: #2 v2.3 has already transport ipv6 by default => doesn't justify putting effort on #1 to keep USE_PF_INET6 ifdef wraps.

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>
| * | Revamped the script-security warning logging (version 2)David Sommerseth2010-04-291-3/+3

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.

* 2.1_rc8 and earlier did implicit shell expansion on scriptjames2008-09-061-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | 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

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
