+1

ChaCha20/Poly1305 actually made it in 5.3.3 [1] and I haven't heard of
any problem on the mailing list.

I too would be glad to give it a spin and report about it.

Indeed! Chacha20 and Poly1305 are cool and getting quite some traction
these days [2].

For the IKE part, the kernel version shouldn't matter. For the ESP part,
you indeed need a recent kernel or you can always use the userspace
implementation (libipsec).

libipsec support is very cool (thanks for enabling it!) as it should
allow running a IPsec in containers.

The reporter was looking for NTRU (enabled in your PPA build IIRC) and
BLISS. That said, I'm sure the reporter would welcome having another
AEAD cipher available because they are well regarded [3] in terms of
security.

Thanks,
