KVM/QEMU + vsock to replace 9pfs
KVM support for vsock and nfs support could have a better performance than 9pfs. This work could be interesting to libreswan KVM testing. It started in 2015. Slowly picking up, as 2018 it seems AWS and firecracker is pushing it. We are almost there.

IPsec and Linux Kernel developments
- XFRM Offload : starting 4.14
* NAT support ??? * What if the interface is a bridge? can libreswan/strongswan configure SA correctly? bridge * what if the packets arrive on different interface would that get decrypted correctly?

Userspace IPsec Stacks
Over last few years specialized user space IPSec(ESP) stacks and IKE implementations are becoming popular.
VPP + DPDK (Userspace ESP + IKE)
VPP has its own IKEv2 and ESP implimentation.
Snabb ESP userspace stack
Snabb as of 2020 has ESP. No IKE, it can easily use of the shelf IKE say strongswan for IKE and and few command line calls to installl snabb esp Snabb FOSDEM 2020 snabb ipsec podcast Strongswan inegeration
