easier for OpenVPN client UIs to start a pre-existing client config file with
proxy options, or to adaptively fall back to a proxy connection if a direct
connection fails.

Improved the ability of http-auth "auto" flag to dynamically detect
the auth method required by the proxy.
Added http-auth "auto-nct" flag to reject weak proxy auth methods.
Added HTTP proxy digest authentication method.
Removed extraneous openvpn_sleep calls from proxy.c.

or "dhcp-renew" options were combined with "route-gateway dhcp".
The problem is that the IP Helper functions for DHCP release and
renew are blocking, and so calling them from a single-threaded
client stops tunnel traffic forwarding, and hence breaks
"route-gateway dhcp" which requires an active tunnel. The fix is
to call the IP Helper functions for DHCP release and renew from
another process.

to clients, including routes. Previously, all pushed options needed
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.

file or pulled from a server) can now be configured via the new
"max-routes" directive.
Previously, the limit was set to 100 and fixed by a compile-time
constant. Now the limit is dynamic and can be modified by the
"max-routes" directive. If max-routes is not specified, the default
limit is 100.
Note that this change does not address the maximum size of the
pushed options string sent from server to client, which is still
controlled by the TLS_CHANNEL_BUF_SIZE compile-time constant.

client will examine the routing table and determine whether (a) the
OpenVPN server is reachable via a locally connected interface, or (b)
traffic to the server must be forwarded through the default router.
Only add a special bypass route for the OpenVPN server if (b) is true.
If (a) is true, behave as if the 'local' flag is specified, and do not
add a bypass route.
The new 'autolocal' flag depends on the non-portable test_local_addr()
function in route.c, which is currently only implemented for Windows.
The 'autolocal' flag will act as a no-op on platforms that have not
yet defined a test_local_addr() function.
Increased TLS_CHANNEL_BUF_SIZE to 2048 from 1024 (this will allow for
more option content to be pushed from server to client).
Raised D_MULTI_DROPPED debug level to 4 from 3.

to be pushed to the client in such a way that they don't accidently
obscure critical local addresses such as the DHCP server address and
DNS server addresses.

versions, the PRNG was hardcoded to use the SHA1
hash. Now any OpenSSL hash may be used. This is
part of an effort to remove hardcoded references to
a specific cipher or cryptographic hash algorithm.

it from being combined with --server directive.
Now, for example, we can configure thusly:
server 10.8.0.0 255.255.255.0 nopool
ifconfig-pool 10.8.0.2 10.8.0.99 255.255.255.0
to have ifconfig-pool manage only a subset
of the VPN subnet.

user-defined authentication script/module is in place (via

Also added management-client-user and management-client-group
directives to control which processes are allowed to connect
to the socket.

from server (rather than only IP address) for --ifconfig, --route, and
--route-gateway. OpenVPN versions 2.1_rc7 and earlier allowed DNS names
for these options to be pulled and translated to IP addresses by default.
Now --allow-pull-fqdn will be explicitly required on the client to enable
DNS-name-to-IP-address translation of pulled options.

Fixed separate compile errors in options.c and ntlm.c that occur
on strict C compilers (such as old versions of gcc) that require
that C variable declarations occur at the start of a {} block,
not in the middle.

DHCP proxy mode: Configure server mode for ethernet
bridging using a DHCP-proxy, where clients talk to the
OpenVPN server-side DHCP server to receive their IP address
allocation and DNS server addresses.
Added "--route-gateway dhcp", to enable the extraction
of the gateway address from a DHCP negotiation with the
OpenVPN server-side LAN.
Modified client.conf and server.conf to reflect new option
modes.
Incremented version to 2.1_rc9a.

* 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.
