* | enhance tls-verify possibilityMathieu GIANNECCHINI2010-10-211-0/+13
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. The man page has been updated and tmp_file in ssl.c is checked for not being NULL before calling delete_file().

* Exclude ping and control packets from activityDavide Brini2010-10-211-5/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: using --ping and --inactive together partially defeats the point of using --inactive as periodic ping packets are counted as activity. Here is the original discussion: http://article.gmane.org/gmane.network.openvpn.devel/3676 It turns out that "activity" is detected and recorded in two places in the code, both in forward.c: in process_outgoing_tun() for received packets, after they've been decrypted and sent to the TUN device; and in process_outgoing_link(), after they've been encrypted and written to the network socket. In the first case we can be sure that packets that get so far are really due to user activity, whereas in the second case there can be non-user packets (like OpenVPN's internal ping packets, and TLS control packets), and those should not be counted as activity as they are not coming from the user. So a need arises to detect those control packets and not count them as activity for the purposes of --inactive. Unfortunately, at that stage packets are already compressed and encrypted, so it's not possible to look into them to see what they are. However, there seems to be a convention in the code that packets whose buffer length in the context_2 structure is 0 should be ignored for certain purposes. TLS control packets follow that convention already, so this patch makes a small change in the code that generates the ping packets to set their buffer length to 0 as well. Finally, the call to register_activity() in process_outgoing_link() is made conditional to the buffer length being > 0. According to my tests, now --inactive behaves correctly according to the configured parameters (time or time+bytes) even when --ping is being used. forward.c: Call register_activity() in process_outgoing_link() only if the packet is not a ping or TLS control packet. openvpn.8: Updated the description of --inactive to describe the new semantics. ping.c: Set c->c2.buf.len = 0 after the ping packet has been generated and encrypted. Test routine is described here: <https://community.openvpn.net/openvpn/wiki/PingInactivePatch?version=6> Signed-off-by: Davide Brini <dave_br@gmx.com> Acked-by: David Sommerseth <dazo@users.sourceforge.net> Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>
* Fix certificate serial number exportDavide Brini2010-10-211-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | contrib/OCSP_check/OCSP_check.sh: New barebone script to demonstrate how to use $tls_serial_{n} to perform simple OCSP queries using OpenSSL command line "openssl ocsp". Minimal sanity checks to fail if user tries to use it without customizing. openvpn.8: Added some notes about $tls_serial_{n} format and usage to the existing description. ssl.c: correctly manage and export serial numbers of any size (as parsed by OpenSSL) into the environment. Set to empty string in case of errors, as 0 and negative numbers are all possible (although illegal) certificate serial numbers. Use an OpenSSL BIO object to do the job. Conforms to coding style guidelines. See the discussion at http://article.gmane.org/gmane.network.openvpn.devel/3588 for more details.

* The man page needs dash escaping in UTF-8 environmentsJan Brinkmann2010-10-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | There was a debian bugreport which was filed in 2005 . It was patched but it seems that nobody forwarded the patch to the openvpn project itself. The problem is quite simple: The dashes for options (the double dashes) are not escaped. This causes trouble in relationship with utf-8 . Since the bugreport was closed it was patched within the debian/ubuntu packages itself. I've attached the patch to get it atleast reviewed by the openvpn project itself.

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
