VSOCK: Don't dec ack backlog twice for rejected connections

2016-09-27T11:59:25+00:00

If a pending socket is marked as rejected, we will decrease the
sk_ack_backlog twice. So don't decrement it for rejected sockets
in vsock_pending_work().

Testing of the rejected socket path was done through code
modifications.

vhost/vsock: drop space available check for TX vq

2016-08-15T02:05:21+00:00

Remove unnecessary use of enable/disable callback notifications
and the incorrect more space available check.

The virtio_transport_tx_work handles when the TX virtqueue
has more buffers available.

VSOCK: defer sock removal to transports

2016-08-01T23:57:28+00:00

The virtio transport will implement graceful shutdown and the related
SO_LINGER socket option.  This requires orphaning the sock but keeping
it in the table of connections after .release().

This patch adds the vsock_remove_sock() function and leaves it up to the
transport when to remove the sock.

VSOCK: transport-specific vsock_transport functions

2016-08-01T23:57:28+00:00

struct vsock_transport contains function pointers called by AF_VSOCK
core code.  The transport may want its own transport-specific function
pointers and they can be added after struct vsock_transport.

Allow the transport to fetch vsock_transport.  It can downcast it to
access transport-specific function pointers.

The virtio transport will use this.

vsock: make listener child lock ordering explicit

2016-06-27T14:44:46+00:00

There are several places where the listener and pending or accept queue
child sockets are accessed at the same time.  Lockdep is unhappy that
two locks from the same class are held.

Tell lockdep that it is safe and document the lock ordering.

Originally Claudio Imbrenda  sent a similar
patch asking whether this is safe.  I have audited the code and also
covered the vsock_pending_work() function.

In netdevice.h we removed the structure in net-next that is being
changes in 'net'.  In macsec.c and rtnetlink.c we have overlaps
between fixes in 'net' and the u64 attribute changes in 'net-next'.

The mlx5 conflicts have to do with vxlan support dependencies.

VSOCK: do not disconnect socket when peer has shutdown SEND only

2016-05-06T03:31:29+00:00

The peer may be expecting a reply having sent a request and then done a
shutdown(SHUT_WR), so tearing down the whole socket at this point seems
wrong and breaks for me with a client which does a SHUT_WR.

Looking at other socket family's stream_recvmsg callbacks doing a shutdown
here does not seem to be the norm and removing it does not seem to have
had any adverse effects that I can see.

I'm using Stefan's RFC virtio transport patches, I'm unsure of the impact
on the vmci transport.
