where credentials are entered from stdin. This capability is
compiled when ENABLE_CLIENT_CR is defined in syshead.h (enabled
by default).
Challenge/response support was previously implemented for creds
that are queried via the management interface. In this case,
the challenge message will be returned as a custom
client-reason-text string (see management-notes.txt for more
info) on auth failure.
Also, see the comments in misc.c above get_auth_challenge()
for info on the OpenVPN challenge/response protocol.

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.

to fit within a 1024 byte options string.
Remember that to make use of this feature to allow many routes to
be pushed to clients, the client config file must specify the
max-routes option, and the number of pushed routes cannot exceed
this limit. Also, both server and client must include this commit.

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.

* 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.

Support asynchronous authentication by plugins by allowing
OPENVPN_PLUGIN_AUTH_USER_PASS_VERIFY to return
OPENVPN_PLUGIN_FUNC_DEFERRED. See comments in

See openvpn/plugin/defer/simple.c for examples of ENABLE_DEF_AUTH

"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.

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
