[Openvpn-devel] [PATCH applied] Re: Fix dco with null cipher being enabled without auth none

[Gert D. <ge...@gr...>]

We know everything about corners inside corner cases!

But we also do them right!

I have not tested this for real - it's fairly trivial anyway, and it has
no memory leaks anymore :-) - the use case is "testing" or "I just need
a tunnel with a more dynamic endpoint than statically-configured GRE,
no crypto needed, and minimum overhead required".  Whether or not this is
a good idea is not addressed by the patch, and OpenVPN itself *will* print
a big fat warning when trying to do "cipher none".

Your patch has been applied to the master branch.
