Commits da9b292733 and
315f6fbc7f broke the use case where we are
asking password from the management client. The password is always asked
before daemonization. With this fix we avoid this and ask it via management
interface in the same spot as before the mentioned commits. Tested on Linux.
v2: This patch was first submitted by Christian Pellegrin (from Google),
and reworked by Steffan Karger (from the OpenVPN team) to also work for
setups with --management-query-passwords but without --auth-user-pass.

This resolves --askpass treating stdin as a file during the file access
check. In turn, this leads to openvpn failing to start if this option is
set to stdin.
By default, --askpass reads the certificate's password from stdin rather
than a file. Without passing the CHKACC_ACPTSTDIN flag to
check_file_access(), stdin is marked as being a nonexistent file.

With the --daemon / SSL init reordering in da9b292733, we fail if we
daemonize first and then try to ask for a private key passphrase (or,
for that matter, username+password if --auth-nocache is set) - but
no meaningful error message was printed, instead depending on operating
system and library versions, either we looped around "ssl init failed"
or died with an unspecified "fatal error".
So: check if get_user_pass_cr() is called in a context that needs
"from_stdin", but both stdin and stderr are not connected to a tty
device (which getpass() needs). In that case, print a meaningful
error message pointing to --askpass, and die.

The init sequence was changed to daemonize before the crypto init to fix
issues on FreeBSD some commits ago. This introduced a regression where
we would no longer query for passwords before daemonizing, as described
in trac #574 and #576.
This commit restores the correct order, and adds a bit of const
correctness since we're touching this now code anyway.

Instead of limiting the control channel TCP/UDP packet payload size at
'100 bytes + real control channel overhead' (~140 bytes ethernet payload),
increase the max TCP/UDP payload size to '1250 bytes - calculated overhead'
(~1210 bytes ethernet payload).
Note that this patch does *not* yield an optimal solution, but it is a
simple and rather safe change that will improve connection setup times
significantly.
v2: use the mininum value of --link-mtu and 1250 to give the user a way to
reduce control packet size if really needed.

When a linux tun interface is closed (e.g. on disconnect)
an optional ipv6 addr that was previously set is deleted now.
Without this patch a later reconnect could fail with
'Linux ip -6 addr add failed: external program exited with error status: 2'
and openvpn would exit.
This is mainly relevant for persistant tun devices (staying around
after openvpn exits) but can also happen at reconnect.
If addresses are *supposed* to stay around on openvpn exit, run
openvpn with --ifconfig-noexec and configure IPv4/IPv6 addresses
manually before openvpn starts (or using an --up script).

* The --help option: An extra parameter for --help generates a
specific error message after showing the syntax message. This
is done to help a user who tries "--help tls-cipher" or similar,
hoping to get more information about the "tls-cipher" option.
* The --dhcp-option option: It has its own similar message, into
which " or extra" has been inserted.
* Ten options such as --up that accept a command (instead of a

error messages that mention double-quoting commands which

using the tun if in point-to-point mode - but for that to fully
work, the "remote" address needs to be different from the "local"

subnet - base+1, if "that is not us", base+2, otherwise.

Previously, the code tried to find res_init(), and on some systems
got it wrong in configure, silently not-using res_init(), leading
to unexpected failures to re-init the resolver.
We know that all supported OSes (except Windows) have res_init(), so
change the call to "#ifndef WIN32", and adjust configure.ac to just
find the library to link (if any). With that, failures to find
res_init() are no longer "hidden" but clearly visible at link time.

Disable record splitting (for now). OpenVPN assumes records are sent
unfragmented, which is no longer a valid assumption when record splitting
is enabled (which polarssl/mbedtls did in 1.3.10, see trac #524).
Changing the code to deal with record splitting will require intrusive
changes that need thorough review and testing. Since OpenVPN is not
susceptible to BEAST (the data transmitted over the control channel is
very hard to influence for a remote attacker), we can just disable record
splitting as a quick fix. This gives us the time to develop a proper
solution in the mean time, and test that thoroughly.

As described in trac #484, the current inline file size limit of 10000
bytes is becoming an issue for some users. Since RSA keys and signature
sizes are increasing, we need to adjust our limits. As #484 reports,
10000 can be too small for PKCS#12 files with 4K RSA keys. Instead of
postponing this issue by increasing the static limit, dynamically increase
the buffer size while reading. This keeps the memory usage limited but does
allow for larger inlined files.

The static helper function possibly_become_daemon() is called only once,
by do_init_first_time(), which checks 'first_time' to be true before
calling possibly_become_daemon(). This makes the parameter useless.

This patch adds support for using certificates stored in the Mac OSX
Keychain to authenticate with the OpenVPN server. This works with
certificates stored on the computer as well as certificates on hardware
tokens that support Apple's tokend interface. The patch is based on
the Windows Crypto API certificate functionality that currently exists
in OpenVPN.
This patch version implements management client which handles RSA-SIGN
command for RSA offloading. Also it handles new 'NEED-CERTIFICATE'
request to pass a certificate from the keychain to OpenVPN.
OpenVPN itself gets new 'NEED-CERTIFICATE" command which is called when
--management-external-cert is used. It is implemented as a multiline
command very similar to an existing 'RSA-SIGN' command.
The patch is against commit 3341a98c28.
v4:
- added '--management-external-cert' argument
- keychain-mcd now parses NEED-CERTIFICATE argument if 'auto' is passed
as cmdline's identity template
- fixed typo in help output option name
- added '--management-external-cert' info in openvpn(8) manpage
- added 'certificate' command documentation into doc/management-notes.txt
v3:
- used new 'NEED-CERTIFICATE' command for certificate data request
instead of 'NEED-OK'
- improved option checking
- improved invalid certificate selection string handling
- added man page for keychain-mcd
- handle INFO, FATAL commands from openvpn and show them to user
* ACK from Arne Schwabe for OpenVPN part
* ACK from James based on Arne's testing
v2 (http://sourceforge.net/p/openvpn/mailman/message/33225603/):
- used management interface to communicate with OpenVPN process
v1 (http://sourceforge.net/p/openvpn/mailman/message/33125844/):
- used RSA_METHOD to extend openvpn itself

The previous Linux/iproute2 code converted binary netmasks to string
representation (print_in_addr_t()), just to immediately scanf() it back
to binary to count bits. netmask_to_netbits2() directly works on the
in_addr_t.

Due to this bug, mssfix hasn't been assigned to fragment value
and used default value (1450) instead. As a consequence, TCP packets
get fragmented, which causes performance penalty.
Since dual stack patch (commit 23d61c56b9)
OpenVPN uses options->connection_list, even for single remote.
This fix assigns mssfix value to fragment value for connection_entry
inside connection_list instead of connection_entry inside options struct
(which does not work for connection_list case).
