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.
Stefan> Thanks, Stefan
