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 "".

by allowing openvpn --mktun to be used with --user and --group
to set the UID/GID of the tun device node. Also added --iproute
option to allow an alternative command to be executed in place
of the default iproute2 command (Alon Bar-Lev).

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.

malicious or compromised server could potentially receive
"setenv" configuration directives from the server which could
cause arbitrary code execution on the client via a LD_PRELOAD
attack. A successful attack appears to require that (a) the
client has agreed to allow the server to push configuration
directives to it by including "pull" or the macro "client" in
its configuration file, (b) the client configuration file uses
a scripting directive such as "up" or "down", (c) the client
succesfully authenticates the server, (d) the server is
malicious or has been compromised and is under the control of
the attacker, and (e) the attacker has at least some level of
pre-existing control over files on the client (this might be
accomplished by having the server respond to a client web request
with a specially crafted file).
The fix is to disallow "setenv" to be pushed to clients from
the server, and to add a new directive "setenv-safe" which is
pushable from the server, but which appends "OPENVPN_" to the
name of each remotely set environmental variable.

connect-retry-max option from
/contrib/alon/BETA21@783.
Added uninit_management_callback call to
init_instance_handle_signals so that
signals thrown during initialization can
bring us back to a management hold.

Allow plugin and push directives to have multiple
parameters specified instead of only 1 quoted
parameter.
Allow plugin and push directives to have multi-line
parameter lists, such as:
<plugin>
my-plugin.so
parm1
parm2
</plugin>

* 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.

used at the same time as --pkcs12, the CA certificate is loaded
from the file specified by --ca regardless if the pkcs12 file
contains a CA cert or not (Mathias Sundman).
