Hi,

as I notice there exists several quic user space implementations, is
there any interest or process of doing an in-kernel implementation? I
am asking because I would like to try out quic with an in-kernel
application protocol like DLM. Besides DLM I've heard that the SMB
community is also interested into such implementation.

Hi!
I'm working on test in-kernel implementation of quic. It's based on the
kernel-tls work and uses the same ULP approach to setup connection
configuration. It's mostly about offload crypto operations of short header
to kernel and use user-space implementation to deal with any other types
of packets. Hope to test it till the end of June with some help from
Jakub.

Thanks, sounds interesting. Does this allow the kernel to create a quic socket?

Not exactly. It's based on top of UDP socket and is configured by setsockopt
like it's done for Kernel TLS implementation. The main point of this work is to
offload cryptography only without implementing special address family.
