Replace copied structure elements with including <net/route.h>
The code for FreeBSD, Dragonfly, OpenBSD and NetBSD contained copies
of structures from <net/route.h> (struct rt_msghdr in particular).
OpenBSD changed some structure elements, making OpenVPN incompatible,
depending on the specific OpenBSD version. Clean up: remove copied
definitions, replace by including <net/route.h> directly - this could
not be done originally due to a conflict with "struct route" in OpenVPN
and <net/route.h>, cleaned up by the previous commit.
Tested on FreeBSD 9.1-RELEASE, NetBSD 5.1, OpenBSD 4.9 (route.c compiles
with no warnings, and "openvpn --show-gateway" works, which is the only
part of the code that uses the structures in question).

Fix spurious ignoring of pushed config options (trac#349).
The function incoming_push_message(...) in push.c uses a local variable
option_types_found, that gets passed to do_up(...).
If the server push got split into several parts, only the last part
(PUSH_MSG_REPLY) option_types_found is used for do_up (initilized as 0
locally), the previous ones (PUSH_MSG_CONTINUATION) are ignored.
So e.g. a ping config, pushed by the server in the first push, followed
by a lot of "push route" configs, causing a second push message, will
have the do_up() called, but without e.g. the OPT_P_TIMER flag, so those
options will be silently ignored.
The patch resolves that, by introducing "push_option_types_found" in
"c->options" and using that as storage.

Use RSA_generate_key_ex() instead of deprecated, RSA_generate_key()
This patch moves from using the deprecated RSA_generate_key() to the 'new'
RSA_generate_key_ex() to generate ephemeral RSA keys. This patch does
not change OpenVPN's behaviour.
One note on the implementation though; the code generates one ephemeral
RSA key that is used during the entire lifetime of an OpenVPN process.
If OpenSSL requests a new (ephemeral) key, it will keep on returning the
same (usually rather small) key. Not the best solution.
To actually run this code, I had to force usage by selecting the
TLS-RSA-EXPORT-WITH-DES40-CBC-SHA tls-cipher. That generated a 512-bit
ephemeral RSA key, and uses the outdated DES encryption protocol.
Using this mode could lead to a false sense of security. Then again, one
should be using (Ephemeral) Diffie-Hellman anyway, and OpenVPN requires
a tls-server to supply dh parameters. A user would need to deliberately
choose a weak tls-cipher like TLS-RSA-EXPORT-WITH-DES40-CBC-SHA, which
would be aligning a gun with his foot anyway. If one would decide this
implementation is not good enough anymore, I'd suggest to just strip out
support for this completely.
Code has been tested using the TLS-RSA-EXPORT-WITH-DES40-CBC-SHA tls-cipher
which uses this to create ephemeral RSA keys.

Refactor tls_ctx_use_external_private_key()
OpenSSL's tls_ctx_load_cert_file() had a parameter in which a copy of the
context's certificate chain was stored on return, used by
tls_ctx_use_external_private_key() only and free()d immediately thereafter.
PolarSSL also supported this output parameter, but returned a pointer to
the
context's certificate chain (rather than to a copy of the certificate, as
OpenSSL does) - which meant that we would have to #ifdef the free().
PolarSSL cannot make a copy of a certificate chain, and OpenSSL cannot
store a
pointer to (instead of a copy of) the cert.
So remove the output parameter from tls_ctx_load_cert_file() and
incorporate
the needed functionality directly into tls_ctx_use_external_private_key()

Examples:
tls-version-min 1.1 -- fail the connection unless peer can
connect at TLS 1.1 or higher.
tls-version-min 1.2 or-highest -- require that the peer
connect at TLS 1.2 or higher, however if the local SSL
implementation doesn't support TLS 1.2 (as it wouldn't
if linked with an older version of OpenSSL), reduce the
minimum required version to the highest version supported

Always push basic set of peer info values to server.
On the client, allow certain peer info fields to be pushed even if
push-peer-info isn't specified in the config.
This is needed to allow the compression handshake to work correctly

Fields that have privacy implications such as Mac Address and UV_*

Subject: [PATCH] Warn when using verb levels >=7 without debug
This patch adds a log warning when using --verb levels at 7 or higher
when running on builds lacking debug support. Since official builds are
now built with enable_debug=no, this warning will help developers
identify why expected debug messages may not be present in log output.
The test and message output code is omitted when built with
enable_debug=yes or enable_small=yes.

Fix parameter listing in non-debug builds at verb 4
When built with enable_debug=no, the parameter output expected at --verb
4 is not printed due to use of #ifdef ENABLE_DEBUG in the responsible
code sections. This appears to be a mistake when looking at the
configure help text for enable_small and enable_debug.
This change keys the relevant code off of enable_small instead,
including the parameter listing when enale_small=no (the
configure-script default.) Most of this code is in options.c, with some
callers present in plugin.c/h and route.c/h. No function code is
changed, just the #ifdef values to use the small feature instead of
debug.
This means builds no longer need enable_debug=yes in order to get the
expected log output at verb 4.

Ignore UTF-8 byte order mark
Currently openvpn exits when reading configuration from a file
that has an UTF-8 byte order mark (EF BB BF) at its start.
While it is useless to put a BOM into UTF-8 encoded files, the
Unicode standard [1] permits it (on page 36):
"Use of a BOM is neither required nor recommended for UTF-8,
but may be encountered in contexts where UTF-8 data is converted
from other encoding forms that use a BOM or where the BOM is
used as a UTF-8 signature."
Notepad.exe, the default text editor on Windows, always puts the BOM
into UTF-8 encoded files when saving them. Others may do as well.
Just ignoring the UTF-8 BOM will make config files with UTF-8 BOM
readable.
