openvpn (2.1~rc15-1) unstable; urgency=low
The openvpn utility changed its handling of pkcs11 certificates when it
switched from built-in code to the pkcs11-helper library (package
libpkcs11-helper1 on Debian). This means that you will have to update your
openvpn configuration files if you are using such certificates. For
example, a stanza in a configuration file might previously have referred to
a given pkcs11 certificate like this:
pkcs11-providers /usr/lib/opensc-pkcs11.so
pkcs11-slot-type id
pkcs11-slot 0
pkcs11-id-type label
pkcs11-id "YOUR_LABEL"
This stanza has to be rewritten now in the following way:
pkcs11-providers /usr/lib/opensc-pkcs11.so
pkcs11-id 'YOUR_PKCS11_SERIALIZED_ID'
The pkcs11-slot, pkcs11-slot-type, pkcs11-id-type options are obsolete;
a long ID string that is unique for each certificate is now used as the
only identifier. Note that YOUR_PKCS11_SERIALIZED_ID will almost
certainly be different from YOUR_LABEL that you used previously with the
pkcs11-id option. To find out the correct serialized ID(s) for your
certificate(s), you have to query the pkcs11-provider library:
$ openvpn --show-pkcs11-ids /usr/lib/opensc-pkcs11.so
The following objects are available for use.
Each object shown below may be used as parameter to --pkcs11-id option
please remember to use single quote mark.
Certificate
DN: /CN=YOUR_USER
Serial: SERIAL_NUMBER
Serialized id: YOUR_PKCS11_SERIALIZED_ID
You have to paste YOUR_PKCS11_SERIALIZED_ID as seen in this output into
your openvpn configuration file and make sure that the string is enclosed
in single quotation marks.
The example above assumes that your cryptographic token can be accessed
via the opensc-pkcs11.so library from libopensc2. If you have to use
another library, for example a proprietary driver from the vendor of your
token, then you have to adapt both the stanza in the configuration file
and the path given on the command line accordingly.

openvpn (2.1~rc9-3) unstable; urgency=low
Calling of external commands/scripts
Starting with version 2.1~rc9, openvpn has a new option to control the
ability to execute external commands (--script-security).
By default (script-security 1) it will only allow the execution of
built-in commands (ip, ifconfig, route,...). If you require the execution
of external commands, such as /etc/openvpn/update-resolv-conf, you'll have
to include the following option in your configuration file:
script-security 2
