The AF_VSOCK address family is a host<->guest communications channel supported by VMware, KVM, and Hyper-V. Initial VMware support was released in Linux 3.9 in 2013 and transports for other hypervisors were added later. AF_VSOCK addresses are <u32 cid, u32 port> tuples. The 32-bit cid integer is comparable to an IP address. AF_VSOCK ports work like TCP/UDP ports. Both SOCK_STREAM and SOCK_DGRAM socket types are available. This patch adds AF_VSOCK support to ss(8) so that sockets can be observed. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> |
