[LEDE-DEV] [PATCH RFC 1/2] openvpn: update to 2.4_rc2
Magnus Kroken
mkroken at gmail.com
Fri Dec 16 16:53:39 PST 2016
OpenVPN 2.4 builds with mbedTLS 2.x, rename openvpn-polarssl
variant to openvpn-mbedtls.
Some feature highlights:
* Data channel cipher negotiation
* AEAD cipher support for data channel encryption (currently only AES-GCM)
* ECDH key exchange for control channel
* LZ4 compression support
See https://github.com/OpenVPN/openvpn/blob/master/Changes.rst
for additional change notes.

- MBEDTLS_DEBUG_C
-
-For targets with space constraints, one might want to compile mbed TLS
-without MBEDTLS_DEBUG_C defined, to save some tens of kilobytes. Make
-sure OpenVPN still compiles if that is the case.
