  Affects: users of security/openvpn

  Author: mandree@FreeBSD.org

  Reason: 
    The security/openvpn port has been updated to v2.5.0, which brings a
    change to the default ciphersuite, which no longer contains BF-CBC.
  
    Some options have been removed. Also, if you need to support very old (v2.3)
    and unsupported clients or servers, you will need to adjust the
    configuration. For details, see:

  Affects: users of security/openvpn, security/openvpn-polarssl

  Author: Matthias Andree <mandree@FreeBSD.org>

  Reason: 
    The OpenVPN ports have been updated to the new upstream release v2.4,
    and their predecessors preserved as openvpn23 and openvpn23-polarssl,
    respectively.  Note that for the new v2.4 release, the
    openvpn-polarssl port has been renamed to openvpn-mbedtls to match the
    upstream library's new name.

security/openvpn: run ldd -a when multi-link of "same" library found

The build runs a sanity to check that libssl and libcrypto are linked
only once, to catch mismatches in SSL providers to libpkcs11-helper
and openvpn itself.  In order to assist the operator to find out
which libraries pull in differing versions of libcrypto or libssl,
run ldd -a in the error path. (Not run normally, not PORTREVISION bump.)

security/openvpn: fix test suite when ifconfig emits ::1/128 address format

Some systems apparently format output of ifconfig lo0 similar to
"inet6 ::1/128" instead of 12.1's "inet6 ::1 prefixlen 128". This
confuses the test script, so strip the slash and trailing prefixlen
off.

Since that bug affects the build-time test suite and its occurrence
breaks the build, no PORTREVISION bump needed.

security/openvpn: Fix illegal client float (CVE-2020-11810)

There is a time frame between allocating peer-id and initializing data
channel key (which is performed on receiving push request or on async
push-reply) in which the existing peer-id float checks do not work right.

If a "rogue" data channel packet arrives during that time frame from another
address and with same peer-id, this would cause client to float to that new
address.

The net effect of this behaviour is that the VPN session for the "victim
client" is broken. Since the "attacker client" does not have suitable keys,
it can not inject or steal VPN traffic from the other session. The time
window is small and it can not be used to attack a specific client's session,
unless some other way is found to make it disconnect and reconnect first.

This fix is inherited by the openvpn-mbedtls slave port.

Fix self-tests in poudriere, make them more robust [1].

The self-tests used to fail in poudriere with dependency cycles in
Makefile that weren't visible earlier. Conditionally change ALL_TARGET
to check (do not use all check, that would require gmake) if the TEST
option is set (default), or set TEST_TARGET if the TEST option is unset.

While I am unable to reproduce 212146 claiming the self-tests fail on an
IPv6-disabled host, and I believe it's a red herring masking a local
configuration issue, doubt sed(1) and add blanks, and be sure to add the
"proto" earlier. The reporter didn't mention his OS version.

No PORTREVISION bump since the default build is unaffected.

security upgrade to OpenVPN 2.3.1; upstream release notes are

  "This release adds supports for PolarSSL 1.2. It also adds a fix to
  prevent potential side-channel attacks by switching to a constant-time
  memcmp when comparing HMACs in the openvpn_decrypt function. In
  addition, it contains several bugfixes and documentation updates, as
  well as some minor enhancements."

Full ChangeLog:
<https://community.openvpn.net/openvpn/wiki/ChangesInOpenvpn23>

The port upgrade also offers an option to use the GPLv2+-licensed
PolarSSL instead of OpenSSL (which brings in a license mix).

Move the rc.d scripts of the form *.sh.in to *.in

Where necessary add $FreeBSD$ to the file

No PORTREVISION bump necessary because this is a no-op

In the rc.d scripts, change assignments to rcvar to use the
literal name_enable wherever possible, and ${name}_enable
when it's not, to prepare for the demise of set_rcvar().

In cases where I had to hand-edit unusual instances also
modify formatting slightly to be more uniform (and in
some cases, correct). This includes adding some $FreeBSD$
tags, and most importantly moving rcvar= to right after
name= so it's clear that one is derived from the other.

Update to new upstream release v2.2.2.

Changelog:
http://openvpn.net/index.php/open-source/documentation/change-log/425-changelog-for-openvpn-22.html

Remove more tags from pkg-descr files fo the form:

- Name
em@i.l

or variations thereof. While I'm here also fix some whitespace and other
formatting errors, including moving WWW: to the last line in the file.

Update and demote CONFLICTS to CONFLICTS_INSTALL.

Use required_modules rather than _precmd.

To fix failures with 'restart'.

Fix skipping t_cltsrv when IP missing. Really this time.

Cause was a   trap "... ; exit 1" 0   shell construct that needs to be
cancelled for the exit 77 to take effect. trap 0 inserted to that end.
