pushed by server, and that is used to offer a temporary session
token to clients that can be used in place of a password on
subsequent credential challenges.
This accomplishes the security benefit of preventing caching
of the real password while offering most of the advantages
of password caching, i.e. not forcing the user to re-enter
credentials for every TLS renegotiation or network hiccup.
auth-token does two things:
1. if password caching is enabled, the token replaces the
previous password, and
2. if the management interface is active, the token is output
to it:
>PASSWORD:Auth-Token:<token>
Also made a minor change to HALT/RESTART processing when password
caching is enabled. When client receives a HALT or RESTART message,
and if the message text contains a flags block (i.e. [FFF]:message),
if flag 'P' (preserve auth) is present in flags, don't purge the Auth
password. Otherwise do purge the Auth password.

LZO, but that has limited interoperability with LZO-enabled servers.
Modified "push-peer-info" option to push IV_LZO_STUB=1 to server when
client was built with --enable-lzo-stub configure option. This tells
the server that the client lacks LZO capabilities, so the server
should turn off LZO compression for this client via "lzo no".
Added "setenv PUSH_PEER_INFO" option having the same effect as
"push-peer-info".

Commit 2e8337de248ef0b5b48cbb2964da0d5c3f28b15b introduced a new
feature for using other SSL certificate fields for authentication
than the CN field.
This commit introduced a bug, which made the verify_callback()
function getting called even if --client-cert-not-required was
enabled in the config.
The reason for this was that an 'else' statement was lacking a
couple of curly braces. The offending commit in reality moved
the setup of the verify_callback() function out of the 'else'
statement.

After some discussion [1] regarding an extension of this feature,
James Yonan wanted this extension to be an opt-in feature. However,
as it does not make sense to opt-in on a extension of a feature which
was discussed, this patch makes the base feature an opt-in instead.
The base feature comes from commit 2e8337de248ef0b5b48cbb2964 (beta2.2)
and commit 935c62be9c0c8a256112 (feat_misc).

This code was not activated at all, and hard coded as disabled in syshead.h
with this code snippet:
/*
* Pthread support is currently experimental (and quite unfinished).
*/
#if 1 /* JYFIXME -- if defined, disable pthread */
#undef USE_PTHREAD
#endif
So no matter if --enable-pthread when running ./configure or not, this feature
was never enabled in reality. 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

The OCSP patch (commit a3982181e284f8c5c8f, feat_misc) introduced
a new function which was calling create_temp_filename(). When merging
in bugfix2.1 into allmerged, create_temp_filename() got renamed to
create_temp_file() in commit 5d30273a8741d2c141.
This patch only changes create_temp_filename() to create_temp_file()
in the new function introduced by commit a3982181e284f8c5c8f.

This patch fixes two bugs introduced in
commit 339f2a4d4b487afa53fa99d72c35b16f31e417d3
Author: David Sommerseth <dazo@users.sourceforge.net>
Date: Thu Apr 29 23:35:45 2010 +0200
David's patch replaced openvpn_execve() with openvpn_run_script() in two places,
but didn't adjust the return value handling. openvpn_run_script() returns true
or false, while openvpn_execve() returns the program's exit code.
Without the fix, the --tls-verify script and the --auth-user-pass-verify
script fail to run. (I noticed the latter, but haven't actually tested the
former.)
The return value handling is fine for the other places where
openvpn_run_script() is used, because those places previously used
openvpn_execve_check() (notice the "_check" suffix).

The main task of this patch is to avoid reporting the SCRIPT_SECURITY_WARNING
over and over again, in addition to not show this warning when it should not
be a problem. 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.

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

exit 1

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().

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.

deferred authentication features in 2.1_rc8.

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
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.

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
as well. -- currently disabled.
5. Many other minor improvements.
