[Pkg-utopia-maintainers] Bug#1012664: Rudamentary patch

[Gard Spreemann]

Hello,

I'm also affected by this bug. Inspection of the upstream code shows
that the NetworkManager OpenVPN plugin has no notion of the
--data-ciphers flag of OpenVPN. The previously used --cipher flag, which
NM does know about, used to imply appending the cipher to the
--data-ciphers list, but that is no longer the case as of OpenVPN 2.6 [1].

I've attached a very rudamentary patch that adds support for
--data-ciphers to network-manager-openvpn, and passes the corresponding
string on as an OpenVPN argument. The patch is a bit crude, and treats
--data-ciphers _exactly_ like --ciphers was already treated. That might
not be appropriate, as the former has the structure of a colon-separated
list, and any GUI/TUI interface might want to reflect that
visually/functionally. My patch treats it as an opaque string.

With the patch, one can in a network-manager-openvpn VPN connection add
an entry of the form

 data-ciphers = WHATEVER

to the .data field of the VPN connection, and WHATEVER will be passed on
to OpenVPN's --data-ciphers argument.

I'll try to have this patch upstreamed, but in the meantime it might be
appropriate for inclusion into Debian so as not to break people's
NM-managed VPN connections upon upgrading OpenVPN.


PS: Simon, you incidate that you are having trouble due to being
unfamiliar with Debian packaging. Do let me know if you'd like me to
provide a precompiled package with the patch included.
