2021-11-28vdpa: Add dummy receive callbackEugenio Pérez
Qemu falls back on userland handlers even if vhost-user and vhost-vdpa cases. These assumes a tap device can handle the packets. If a vdpa device fail to start, it can trigger a sigsegv because of that. Add dummy receiver that returns no progress so it can keep running.

2021-11-15vdpa: Replace qemu_open_old by qemu_open atEugenio Pérez
There is no reason to keep using the old one, since we neither use the variadics arguments nor open it with O_DIRECT. Also, net_client_init1, the caller of net_init_vhost_vdpa, wants all net_client_init_fun to use Error API, so it's a good step in that direction.

2021-10-15net/vhost-vdpa: Fix device compatibility checkKevin Wolf
vhost-vdpa works only with specific devices. At startup, it second guesses what the command line option handling will do and error out if it thinks a non-virtio device will attach to them. This second guessing is not only ugly, it can lead to wrong error messages ('-device floppy,netdev=foo' should complain about an unknown property, not about the wrong kind of network device being attached) and completely ignores hotplugging. Drop the old checks and implement .check_peer_type() instead to fix this. As a nice side effect, it also removes one more dependency on the legacy QemuOpts infrastructure and even reduces the code size.

2021-08-26net: Zero sockaddr_in in parse_host_port()Peter Maydell
We don't currently zero-initialize the 'struct sockaddr_in' that parse_host_port() fills in, so any fields we don't explicitly initialize might be left as random garbage. POSIX states that implementations may define extensions in sockaddr_in, and that those extensions must not trigger if zero-initialized. So not zero initializing might result in inadvertently triggering an impdef extension. memset() the sockaddr_in before we start to fill it in.
