Thanks for CC me. I think it's related to this issue: https://gitlab.com/vsock/vsock/-/issues/1

virtio-vsock provides a credit mechanism, but we need to improve the memory tracking, maybe reusing sk_sndbuf and sk_rcvbuf.

Unfortunately, when vsock was introduce it adds is own IOCTL to set the buffer size, so we need to clean up a bit that part.

I can't work on it right now, maybe in the next months I can, but I can help for sure if someone has time.

Thanks,
Stefano
