From: Antonio Quartulli <antonio@openvpn.net>
The current interface limits the nonce 64bit, however, new users
may want to specify a 96bit nonce, as dictated by the
AEAD_CHACHA20_POLY1305 construction in RFC7539 Section 2.8.
This patch changes the interface from accepting the nonce as single u64
variable to an array of 12 bytes.
Since ChaCha still expects an IV of 16 bytes, the nonce is transferred
to a termporary 16byte long buffer, where the initial 8 bytes are set to
0 (ChaCha block counter).
At the end of the procedure, the IV is explicitly overwritten with
zeros.
The only two in-tree users of this interface are:
- WireGuard[tm]
- security/keys/big_key.c
Both have been modified accordingly to accommodate the new API.
The chacha20poly1305-selftest has also been updated by getting rid of the
_bignonce() wrapper and by prepending every 8byte long nonce with 4
0-octects..

Note: I am not 100% sure that the WireGuard[tm] adaptation to the new
API is optimal. But after several attempts, this is the simplest I could
come up with. Feedback is welcome!
*******
For the curious reader: the "other user" I am concerned about is
ovpn-dco.
ovpn-dco is the implementation of the OpenVPN data channel offload in
kernelspace.
It is currently under heavy development and the source code is available
online at: git@gitlab.com:openvpn/ovpn-dco.git
Next to AES-GCM it will also support ChaCha20Poly1305 and therefore we
decided to re-use this relatively new API.

Nack.
This API is meant to take simple integers, so that programmers can use
atomic64_t with it and have safe nonces. I'm also interested in
preserving the API's ability to safely encrypt more than 4 gigs of
data at once. Passing a buffer also encourages people to use
randomized nonces, which isn't really safe. Finally, there are no
in-tree users of 96bit nonces for this interface. If you're after a
cornucopia of compatibility primitives, the ipsec stuff might be more
to your fitting. Or, add a new simple function/api. But adding
complexity to users of the existing one and confusing future users of
it is a non-starter. It's supposed to be deliberately non-awful to
use.

If you are going back to the drawing board with in-kernel acceleration
for OpenVPN, I strongly suggest to:
a) either stick to one implementation, and use the library interface,
or use dynamic dispatch using the crypto API AEAD abstraction, which
already implements 96-bit nonces for ChaCha20Poly1305,
b) consider using Aegis128 instead of AES-GCM or ChaChaPoly - it is
one of the winners of the CAESAR competition, and on hardware that
supports AES instructions, it is extremely efficient, and not
encumbered by the same issues that make AES-GCM tricky to use.
We might implement a library interface for Aegis128 if that is preferable.

As far as I can tell, they're mostly after compatibility with their
existing userspace stuff. Otherwise, if they were going back to the
drawing board, they could just make openvpn userspace set up xfrm or
wg tunnels to achieve basically the same design. And actually, the
xfrm approach kind of makes a lot of sense for what they're doing; it
was designed for that type of split-daemon tunneling design.

Thanks for explaining the ratio behind this API.
At first I thought this API wanted to take over the existing one, hence
my attempt of making it more generic and re-use it.
But I understand now this was not the goal.
I will stick to the classic crypto API then.
Best Regards,
p.s. I am curious about any use case you may have in mind for encrypting
more than 4GB in one go, as there are no users doing that right now.

What we are implementing is a simple Data Channel Offload, which is
expected to be compatible with the current userspace implementation.
Therefore we don't want to change how encryption is performed.
Using the crypto API AEAD abstraction will be my next move at this point.
I just find it a bit strange that an API of a well defined crypto schema
is implemented in a way that accommodates only some of its use cases.
But I guess it's accepted that we will have to live with two APIs for a bit.

Thanks for the pointer!
I guess we will consider supporting Aegis128 once it gets standardized
(AFAIK it is not yet).

You mean the 64-bit nonce used by the library version of
ChaCha20Poly1305? I agree that this is a bit unusual, but a library
interface doesn't seem like the right abstraction for this in the
first place, so I guess it is irrelevant.

It is. The CAESAR competition is over, and produced a suite of
recommended algorithms, one of which is Aegis128 for the high
performance use case. (Note that other variants of Aegis did not make
it into the final recommendation)

Yes, correct. That's why I had no real objection to using it :-)
At first I was confused and I thought this new library interface was
"the preferred way" for using chacha20poly1305, therefore I went down
this path.

oops, I was not up-to-date. Thanks again!
We'll definitely look into this soon.
