Subject: [PATCH net-next 00/14] vsock: add multi-transports support
Date: Wed, 23 Oct 2019 11:55:40 +0200 [thread overview]
Message-ID: <20191023095554.11340-1-sgarzare@redhat.com> (raw)
This series adds the multi-transports support to vsock, following
this proposal: https://www.spinics.net/lists/netdev/msg575792.html
With the multi-transports support, we can use VSOCK with nested VMs
(using also different hypervisors) loading both guest->host and
host->guest transports at the same time.
Before this series, vmci-transport supported this behavior but only
using VMware hypervisor on L0, L1, etc.
RFC: https://patchwork.ozlabs.org/cover/1168442/
RFC -> v1:
- Added R-b/A-b from Dexuan and Stefan
- Fixed comments and typos in several patches (Stefan)
- Patch 7: changed .notify_buffer_size return to void (Stefan)
- Added patch 8 to simplify the API exposed to the transports (Stefan)
- Patch 11:
+ documented VSOCK_TRANSPORT_F_* flags (Stefan)
+ fixed vsock_assign_transport() when the socket is already assigned
+ moved features outside of struct vsock_transport, and used as
parameter of vsock_core_register() as a preparation of Patch 12
- Removed "vsock: add 'transport_hg' to handle g2h\h2g transports" patch
- Added patch 12 to register vmci_transport only when VMCI guest/host
are active
The first 9 patches are cleanups and preparations, maybe some of
these can go regardless of this series.
Patch 10 changes the hvs_remote_addr_init(). setting the
VMADDR_CID_HOST as remote CID instead of VMADDR_CID_ANY to make
the choice of transport to be used work properly.
Patch 11 adds multi-transports support.
Patch 12 touch a little bit the vmci_transport and the vmci driver
to register the vmci_transport only when there are active host/guest.
Patch 13 prevents the transport modules unloading while sockets are
assigned to them.
Patch 14 fixes an issue in the bind() logic discoverable only with
the new multi-transport support.
I've tested this series with nested KVM (vsock-transport [L0,L1],
virtio-transport[L1,L2]) and with VMware (L0) + KVM (L1)
(vmci-transport [L0,L1], vhost-transport [L1], virtio-transport[L2]).
Dexuan successfully tested the RFC series on HyperV with a Linux guest.
Stefano Garzarella (14):
vsock/vmci: remove unused VSOCK_DEFAULT_CONNECT_TIMEOUT
vsock: remove vm_sockets_get_local_cid()
vsock: remove include/linux/vm_sockets.h file
vsock: add 'transport' member in the struct vsock_sock
vsock/virtio: add transport parameter to the
virtio_transport_reset_no_sock()
vsock: add 'struct vsock_sock *' param to vsock_core_get_transport()
vsock: handle buffer_size sockopts in the core
vsock: add vsock_create_connected() called by transports
vsock: move vsock_insert_unbound() in the vsock_create()
hv_sock: set VMADDR_CID_HOST in the hvs_remote_addr_init()
vsock: add multi-transports support
vsock/vmci: register vmci_transport only when VMCI guest/host are
active
vsock: prevent transport modules unloading
vsock: fix bind() behaviour taking care of CID
