I have allocated #define DLT_VSOCK 271 Stefan> Hi, Gerard Garcia previously requested a linktype for AF_VSOCK in Stefan> July 2016 (http://seclists.org/tcpdump/2016/q3/17). I am picking Stefan> up his work now that the vsockmon Linux kernel module has been Stefan> merged upstream. The header files and struct definitions are Stefan> available as part of the Linux kernel headers. Stefan> AF_VSOCK is a guest<->host communications mechanism available in Stefan> VMware and KVM hypervisors. It is not based on Ethernet or IP Stefan> but offers SOCK_STREAM and SOCK_DGRAM (only on VMware) semantics Stefan> analogous to TCP and UDP. Stefan> The vsockmon packet capture headers are here: Stefan> https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/include/uapi/linux/vsockmon.h Stefan> The virtio-vsock transport headers are here: Stefan> https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/include/uapi/linux/virtio_vsock.h Stefan> For your convenience I have included a full header description Stefan> below based on a draft previously posted by Guy Harris. Stefan> You can find more information about virtio-vsock and how to try Stefan> it out at http://qemu-project.org/Features/VirtioVsock. Stefan> Please assign a linktype for AF_VSOCK.
