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.

success/error, and any truncation of output due to an insufficiently
large output buffer will be cause for error.
In verify_callback, read X509 Subject Name without truncation.
In verify_callback, rather than silently truncating Common Name at
64 bytes, throw an error if Common Name is larger than 64 bytes.

Added client authentication and packet filtering capability
to management interface.
Extended packet filtering capability to work on both --dev tun
and --dev tap tunnels.
Updated valgrind-suppress file.
Made "Linux ip addr del failed" error nonfatal.
Amplified --client-cert-not-required warning.
Added #pragma pack to proto.h.

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.
setenv and setenv-safe directives may now omit a value argument
which defaults to "".

Implemented AUTO_USERID using
MD5(MAC address(primary network adapter)).
Currently implemented for Linux and Windows.
Basically if ENABLE_AUTO_USERID is defined,
the --auth-user-pass option will not prompt
for username/password, but will rather generate
a unique username and blank password.

back in r893 which causes TLS soft resets
(1 per hour by default) in TCP server mode to force
a blockage of tunnel packets and later time-out and
restart the connection.

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.

* Added code to make sure that the local PATH environmental
variable points to the Windows system32 directory.
* Added new --ip-win32 adaptive mode which tries 'dynamic'
and then fails over to 'netsh' if the DHCP negotiation fails.
* Made --ip-win32 adaptive the default.

from the file specified by --ca regardless if the pkcs12 file
contains a CA cert or not (Mathias Sundman).
