I'm not a native speaker but maybe is better 'connection oriented' or
looking at socket(2) man page 'connection-based' is also fine.

This adds rest of logic for SEQPACKET:

2) SEQPACKET specific functions which send SEQ_BEGIN/SEQ_END.
Note that both functions may sleep to wait enough
Please move this patch before the test and I'd change the prefix in
"vsock_loopback" or "vsock/loopback".
Thanks,

Commit 65b709586e222fa6ffd4166ac7fdb5d5dad113ee upstream.
Before this patch, if 'offset + len' was equal to
sizeof(struct virtio_net_config), the entire buffer wasn't filled,
returning incorrect values to the caller.
Since 'vdpasim->config' type is 'struct virtio_net_config', we can
safely copy

Sorry, I should have paid more attention.

Hi guys,
I am working on supporting DGRAM type for virtio/vhost vsock. I
already did some work and a draft code is here (which passed my tests,
but still need some cleanup and only works from host to guest as of
now, will add host to guest soon):
