In the vsock vmci_transport driver, sock_put wasn't safe to call in interrupt context, since that may call the vsock destructor which in turn calls several functions that should only be called from process context. This change defers the callling of these functions to a worker thread. All these functions were deallo...

virtio_transport and vmci_transport handle the buffer_size sockopts in a very similar way. In order to support multiple transports, this patch moves this handling in the core to allow the user to change the options also if the socket is not yet assigned to any transport. This patch also adds the '.notify_buffer_size' c...

...ansport() 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...

Most of the patches are reviewed by Dexuan, Stefan, and Jorgen. The following patches need reviews: - [11/15] vsock: add multi-transports support - [12/15] vsock/vmci: register vmci_transport only when VMCI guest/host are active - [15/15] vhost/vsock: refuse CID assigned to the guest->host transport RFC: https://patchwork.ozlabs.org/cover/1168442/ v1: https://patchwork.ozlabs.org/cover/1181986/ v1 -> v2: - Patch 11: + vmci_transport: sent reset when vsock_assi...

...ork on it now, or when another transport will support DGRAM. The big issues here is that we cannot link 1-1 a socket to transport as for stream sockets since DGRAM is not connection-oriented. Patches 11 and 12 maybe can be merged with patch 10. Patch 11 maybe is tricky, but it allows to have vmci_transport and vhost_vsock loaded at the same time and it also alleviates the problem of having MODULE_ALIAS_NETPROTO(PF_VSOCK) in vmci_transport.c Patch 12 prevents the transport modules unloading while sockets are assigned to them. Patch 13 fixes an issue in the bind() logic discoverable only with the...
