[Virtio-fs] virtiofsd-rs: A rust virtiofs daemon

[Virtio-fs] virtiofsd-rs: A rust virtiofs daemon

[Dr. David Alan Gilbert]

Hi,
  Sergio has been working on virtiofsd-rs, a virtiofs daemon
written in rust, and which can be found at:

  https://gitlab.com/virtio-fs/virtiofsd-rs

It started life originally as part of the crosvm project, got
ported to vhost-user as part of the Cloud Hypervisor project, and
has now been split out.

While the C version of virtiofsd isn't going away for now, the hope
is to stabilise virtiofsd-rs, add some missing features and start
preferentially adding new features and new work onto the Rust version
rather than the C version.

So please try it, and let the list (and Sergio!) know how you get on.

Dave

Awesome, really happy that the Rust daemon has come so far. Thanks
Chirantan, Sebastien, Sergio, and everyone else who developed it.

I talked to Sergio and he is currently looking at what's missing for
feature parity with C virtiofsd. This is an opportunity for anyone who
wants to contribute.

In response to this post[1]:

Is the feature parity list documented somewhere? I would like to help.

Thank you,

Connor

(Is something wrong with the archives for this list? I tried downloading 
the December 2020 posts to import into Thunderbird but it only contained 
the very first message from December)

Probably the biggest missing piece is xattr mapping:

https://gitlab.com/virtio-fs/virtiofsd-rs/-/issues/3

The other was remote locks, but we already have a MR for that:

https://gitlab.com/virtio-fs/virtiofsd-rs/-/issues/2
https://gitlab.com/virtio-fs/virtiofsd-rs/-/merge_requests/4

I'd also be nice keeping an eye on the improvements that are being
made on fuse-backend-rs [1] to see if we can cherry-pick some of them.

Thanks!
Sergio.
