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) On 8/21/23 09:55, Xin Long wrote: > 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.

I just did some research, and this engine (in C) appears to be easiest to use for Samba. https://github.com/litespeedtech/lsquic/blob/master/docs/tutorial.rst The tutorial shows an example being used with libevent, we could adapt this to libtevent. ^ permalink raw reply [flat|nested] 2+ messages in thread
