We are implementing a test suite for the VSOCK sockets and we discovered that vmci_transport never allowed half-closed socket on the host side. As Jorgen explained [1] this is due to the implementation of VMCI. Since we want to have the same behaviour across all transports, this series adds a section in the "Implementation notes" to exaplain this behaviour, and changes the

Hello, I'm trying to find out how to pxe boot with syslinux.efi on QEMU with OVMF. After getting through the initial hurdle caused by the iPXE based option ROM included with QEMU having a problem as described in these threads: http://www.syslinux.org/archives/2014-November/022804.html http://sourceforge.net/p/edk2/mailman/message/33236100/ I'm now getting further to almost being able

At first glance it seems strange, because if sk_state is TCP_ESTABLISHED, the transport shouldn't be NULL, that's why we didn't put the check. Stefano

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:

Hi all, 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
