Security fixes:
CVE-2025-2704: fix possible ASSERT() on OpenVPN servers using --tls-crypt-v2
Security scope: OpenVPN servers between 2.6.1 and 2.6.13 using --tls-crypt-v2 can be made
to abort with an ASSERT() message by sending a particular combination of authenticated and
malformed packets. No crypto integrity is violated, no data is leaked, and no remote code
execution is possible. This bug does not affect OpenVPN clients.

This is a bugfix release containing several security fixes.
Security fixes
--------------
- CVE-2024-4877: Windows: harden interactive service pipe.
Security scope: a malicious process with "some" elevated privileges
could open the pipe a second time, tricking openvn GUI
into providing user credentials (tokens), getting full access
to the account openvpn-gui.exe runs as.
- CVE-2024-5594: control channel: refuse control channel messages
with nonprintable characters in them.
Security scope: a malicious openvpn peer can send garbage to openvpn log,
or cause high CPU load.
- CVE-2024-28882: only call schedule_exit() once (on a given peer).
Security scope: an authenticated client can make the server "keep the session"
even when the server has been told to disconnect this client
Bug fixes
---------
- fix connect timeout when using SOCKS proxies
- work around LibreSSL crashing on OpenBSD 7.5 when enumerating ciphers
- Add bracket in fingerprint message and do not warn about missing verification

- license change is now complete, and all code has been re-licensed
under the new license (still GPLv2, but with new linking exception
for Apache2 licensed code).
Code that could not be re-licensed has been removed or rewritten.
- add support for building with mbedTLS 3.x.x
- new option "--force-tls-key-material-export" to only accept clients
that can do TLS keying material export to generate session keys
(mostly an internal option to better deal with TLS 1.0 PRF failures).
- Windows: bump vcpkg-ports/pkcs11-helper to 1.30
- Log incoming SSL alerts in easier to understand form and move logging
from "--verb 8" to "--verb 3".
- protocol_dump(): add support for printing "--tls-crypt" packets
and other fixes

This is a bugfix release containing security fixes.
Security Fixes (included in 2.6.7):
CVE-2023-46850 OpenVPN versions between 2.6.0 and 2.6.6 incorrectly use a send buffer
after it has been free()d in some circumstances, causing some free()d memory to be sent to the peer.
All configurations using TLS (e.g. not using --secret) are affected by this issue.
CVE-2023-46849 OpenVPN versions between 2.6.0 and 2.6.6 incorrectly restore --fragment configuration
in some circumstances, leading to a division by zero when --fragment is used.
On platforms where division by zero is fatal, this will cause an OpenVPN crash.

This commit updates openvpn to version 2.6.5 and add DCO support.
There are several changes:
- Starting with version 2.6.0, the sources are only provided as .tar.gz
file.
- removed OPENVPN_<variant>_ENABLE_MULTIHOME:
multihome support is always included and cannot be disabled anymore
with 2.6.x.
- removed OPENVPN_<variant>_ENABLE_DEF_AUTH:
deferred auth support is always included and cannot be disabled
anymore with 2.6.x.
- removed OPENVPN_<variant>_ENABLE_PF:
PF (packet filtering) support was removed in 2.6.x.
- The internal lz4 library was removed in 2.6.x; we now use the liblz4
package if needed
- To increase reproducibility, _DATE_ is only used for development
builds and not in release builds in 2.6.x.
- wolfSSL support was integrated into upstream openvpn
- DES support was removed from openvpn
The first two wolfSSL patches were created following these 2 commits:

Fix a possible security issue with OpenSSL config autoloading on Windows (CVE-2021-3606).
Include a number of small improvements and bug fixes.

Fixes two related security vulnerabilities (CVE-2020-15078) which
under very specific circumstances allow tricking a server using delayed
authentication (plugin or management) into returning a PUSH_REPLY before
the AUTH_FAILED message, which can possibly be used to gather
information about a VPN setup. In combination with "--auth-gen-token" or
a user-specific token auth solution it can be possible to get access to
a VPN with an otherwise-invalid account.
OpenVPN 2.5.2 also includes other bug fixes and improvements.
Add CI build test script.

New features:
* Per client tls-crypt keys
* ChaCha20-Poly1305 can be used to encrypt the data channel
* Routes are added/removed via Netlink instead of ifconfig/route
(unless iproute2 support is enabled).
* VLAN support when using a TAP device
Significant changes:
* Server support can no longer be disabled.
* Crypto support can no longer be disabled, remove nossl variant.
* Blowfish (BF-CBC) is no longer implicitly the default cipher.
OpenVPN peers prior to 2.4, or peers with data cipher negotiation
disabled, will not be able to connect to a 2.5 peer unless
option data_fallback_ciphers is set on the 2.5 peer and it contains a
cipher supported by the client.
