I was very interested in this as well and there seems to be a logical
use case for SMB3.1.1 mounts from the kernel client (cifs.ko) since
multiple servers already support QUIC for SMB3.1.1 mounts (e.g.
Windows and apparently also an embedded server that demoed at Storage
Developer Conference last year). Key question remains how much of the
code can stay in userspace (so only the key socket read/write code
must be in kernel, not necessarily the connection setup). There are
also some interesting points that the Microsoft QUIC (open source
project in github) project guys mentioned including that for testing
you can often do "unencrypted QUIC" as a first step (which also has
performance benefits over TCP)
We can discuss more details if you want, but Wedson had some great
ideas about doing some of this in Rust (and looks there are already 3
work in progress user space opensource QUIC implementations in Rust -
so some of the code could be reused)

Hi, Samba Team,
I'm currently working on QUIC implementation in Linux Kernel, and thinking
of applying it to fs/smb for SMB over QUIC in kernel. For interoperability
testing, I'm looking for an existing userspace implementation for SMB over
QUIC in Linux.
I heard there are already some internal patches in samba for SMB over QUIC
support, anyone knows where I can get it for this testing?
I just did some research, and this engine (in C) appears to be easiest
to use for Samba.

The tutorial shows an example being used with libevent, we could
adapt this to libtevent.
