[PATCH v2] openvpn: update to 2.5.0

Magnus Kroken mkroken at gmail.com
Tue Dec 1 04:57:07 EST 2020


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.

v2: Fix missed -/_ conversion in openvpn.options, thanks Jo for pointing
this out. Restored LZO as enabled by default to ease the version update,
proposal to disable LZO will be sent as a separate patch.
