It's not a complex task to add support for unix sockets, but the socket netdev parameters are not defined to manage well unix socket parameters. As discussed in: "socket.c added support for unix domain socket datagram transport" https://lore.kernel.org/qemu-devel/1C0E1BC5-904F-46B0-8044-68E43E67BE60@gmail.com/ This series adds support of unix socket type using SocketAddress QAPI structure. A new netdev backend "socket-ng" is added, that is barely a copy of "socket" backend but it uses the SocketAddress QAPI to provide socket parameters. And then it also implement unix sockets (TCP and UDP). Some examples of CLI syntax: for TCP: -netdev socket-ng,id=socket0,mode=server,addr.type=inet,addr.host=localhost,addr.port=1234 -netdev socket-ng,id=socket0,mode=client,addr.type=inet,addr.host=localhost,addr.port=1234 -netdev socket-ng,id=socket0,mode=dgram,\ local.type=inet,local.host=localhost,local.port=1234,\ remote.type=inet,remote.host=localhost,remote.port=1235 for UNIX: -netdev socket-ng,id=socket0,mode=server,addr.type=unix,addr.path=/tmp/qemu0 -netdev socket-ng,id=socket0,mode=client,addr.type=unix,addr.path=/tmp/qemu0 -netdev socket-ng,id=socket0,mode=dgram,\ local.type=unix,local.path=/tmp/qemu0,\ remote.type=unix,remote.path=/tmp/qemu1 for FD: -netdev socket-ng,id=socket0,mode=server,addr.type=fd,addr.str=4 -netdev socket-ng,id=socket0,mode=client,addr.type=fd,addr.str=5 -netdev socket-ng,id=socket0,mode=dgram,local.type=fd,addr.str=4 CC: Ralph Schmieder CC: Stefano Brivio CC: Daniel P.
