* Added "setenv opt" directive prefix. If present, and if theJames Yonan2013-07-151-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | directive that follows is recognized, it will be processed as if the "setenv opt" prefix was absent. If present and if the directive that follows is not recognized, the directive will be ignored rather than cause a fatal error. For example, suppose you are distributing a client configuration file and want to set the minimum TLS version that the client requires from the server to 1.2. By using the following directive, setenv opt tls-version-min 1.2 or-highest only newer clients that understand the tls-version-min directive would process it, while older clients would ignore it.

* TLS version negotiationJames Yonan2013-07-116-4/+139
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Updated the TLS negotiation logic to adaptively try to connect using the highest TLS version supported by both client and server. Previously, OpenVPN (when linked with OpenSSL) would always connect using TLS 1.0. Also added tls-version-min directive to force a higher TLS version than 1.0: tls-version-min <version> ['or-highest'] -- sets the minimum TLS version we will accept from the peer. Examples for version include "1.0" (default), "1.1", or "1.2". If 'or-highest' is specified and version is not recognized, we will only accept the highest TLS version supported by the local SSL implementation. Examples: tls-version-min 1.1 -- fail the connection unless peer can connect at TLS 1.1 or higher. tls-version-min 1.2 or-highest -- require that the peer connect at TLS 1.2 or higher, however if the local SSL implementation doesn't support TLS 1.2 (as it wouldn't if linked with an older version of OpenSSL), reduce the minimum required version to the highest version supported by the local SSL implementation (such as TLS 1.0). This is intended to allow client configurations to target higher TLS versions that are supported on the server, even if some older clients don't support these versions yet.

* plugin: Extend the plug-in v3 API to identify the SSL implementation usedDavid Sommerseth2013-07-032-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OpenVPN would segfault unexpectedly if it would be compiled against PolarSSL and the plug-in would expect OpenSSL, or vice-versa. This segfault would not appear before the plug-in would try to access functions which would be available if the plug-in and OpenVPN uses the same SSL implementation. This patch adds a member to the plug-in initialisation function, which identifies the SSL implementation. The log_v3 plug-in is updated accordingly + a simple fix to make it buildable again using the ./build script. A minor documentation error in the openvpn-plugin.h was also corrected, where it mentioned OPENVPN_PLUGIN_VERSION instead of OPENVPN_PLUGINv3_STRUCTVER. v2 - add const ovpnSSLAPI ssl_api at the end of struct openvpn_plugin_args_open_in and not in the "middle" v3 - fix bug in plug-in init, as the SSLAPI was located wrong in the args struct sent to the openvpn_plugin_open_v3() function. v4 - Ensure SSLAPI got a sane/known value if SSL is disabled or unknown Signed-off-by: David Sommerseth <davids@redhat.com> Acked-by: Gert Doering <gert@greenie.muc.de> Message-Id: <1372879030-10576-1-git-send-email-dazo@users.sourceforge.net> URL: http://article.gmane.org/gmane.network.openvpn.devel/7754 Signed-off-by: Gert Doering <gert@greenie.muc.de>

* Make push-peer-info visible in "normal" per-instance environment.Gert Doering2013-05-275-44/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without this patch, peer-info pushed by clients in the TLS handshake is only visible on the management interface, and only if --management-client-auth is enabled. With this patch, received records are sanitized and put into the normal "multi instance" environment, where it can be evaluated by --client-connect or --auth-user-pass-verify scripts and plugins, etc. Only records matching a fairly strict "name=value" format are accepted, and only names starting with IV_ or UV_ are exported, to avoid clients sending funny stuff and playing havoc with script/plugin environments on the server. In the "value" part, spaces, non-printable characters and shell metacharacters are replaced by '_'. The change is somewhat invasive as reception of the peer_info string was only done when username+password are expected from the client, but the data is always there (if the client sends no username/password, it will send 0-length strings, so always extracting 3 strings is safe). Also, the sanitation function validate_peer_info_line() and the opts->peer_info field were only compiled in #ifdef MANGEMENT_DEF_AUTH... Patch v3: do not call the old man_output_peer_info_env() anymore, unless a management env-filter has been set (= ensure IV_ and UV_ stuff is sent at most *once*, and exactly the way OpenVPN AS expects it). Add substituting of "bad" characters in the environment values.

* Added support for the Snappy compression algorithmJames Yonan2013-05-1917-393/+898
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added support for the Snappy compression algorithm which has shown to have considerably better compression speed than LZO at a comparable compression ratio. To enable Snappy add: compress snappy to both client and server config files. Alternatively, enable compression framing on the client: compress and have the server selectively push "compress snappy" to the client. This change also extends the client capability handshake to include IV_SNAPPY so the server can be aware that a connecting client supports Snappy. Note that the Snappy implementation also includes an improved framing approach where the first byte of the compressed payload is replaced by the compression control byte (the first payload byte is moved to the end of the packet). This solves off-by-one alignment issues, which improves performance on ARM. By default, the configure script will try to build with Snappy support. To disable, use the --disable-snappy option. The --enable-lzo-stub configure directive is now --enable-comp-stub (because it's not actually "lzo" but "compression-enabled packet framing") Add compression overhead to extra buffer unconditionally, as long as USE_COMP is defined.

It was working in f0eac1a59790, and got broken by the route.c/route.h refactoring in 576dc96ca1ef1 - the patch un-does that change to the TARGET_SOLARIS code, plus adds some more descriptive comments.

Since official builds are now built with enable_debug=no, this warning will help developers identify why expected debug messages may not be present in log output. The test and message output code is omitted when built with enable_debug=yes or enable_small=yes.

* Fix parameter listing in non-debug builds at verb 4Josh Cepek2013-03-145-11/+11
| | | | | | | | | | | | | | | | | | | | | | | When built with enable_debug=no, the parameter output expected at --verb 4 is not printed due to use of #ifdef ENABLE_DEBUG in the responsible code sections. This appears to be a mistake when looking at the configure help text for enable_small and enable_debug. This change keys the relevant code off of enable_small instead, including the parameter listing when enale_small=no (the configure-script default.) Most of this code is in options.c, with some callers present in plugin.c/h and route.c/h. No function code is changed, just the #ifdef values to use the small feature instead of debug. This means builds no longer need enable_debug=yes in order to get the expected log output at verb 4.
