2022-10-28tests/qtest: libqtest: Correct the timeout unit of blocking receive calls ↵Bin Meng
for win32 Some qtest cases don't get response from the QEMU executable under test in time on Windows. It turns out that the socket receive call got timeout before it receive the complete response. The timeout value is supposed to be set to 50 seconds via the setsockopt() call, but there is a difference among platforms. The timeout unit of blocking receive calls is measured in seconds on non-Windows platforms but milliseconds on Windows.

2022-10-28tests/qtest: Use send/recv for socket communicationXuzhou Cheng
Socket communication in the libqtest and libqmp codes uses read() and write() which work on any file descriptor on *nix, and sockets in *nix are an example of a file descriptor. However sockets on Windows do not use *nix-style file descriptors, so read() and write() cannot be used on sockets on Windows.

2022-10-28qapi: net: add stream and dgram netdevsLaurent Vivier
Copied from socket netdev file and modified to use SocketAddress to be able to introduce new features like unix socket. "udp" and "mcast" are squashed into dgram netdev, multicast is detected according to the IP address type. "listen" and "connect" modes are managed by stream netdev. An optional parameter "server" defines the mode (off by default) The two new types need to be parsed the modern way with -netdev, because with the traditional way, the "type" field of netdev structure collides with the "type" field of SocketAddress and prevents the correct evaluation of the command line option. Moreover the traditional way doesn't allow to use the same type (SocketAddress) several times with the -netdev option (needed to specify "local" and "remote" addresses). The previous commit paved the way for parsing the modern way, but omitted one detail: how to pick modern vs. traditional, in netdev_is_modern(). We want to pick based on the value of parameter "type". But how to extract it from the option argument? Parsing the option argument, either the modern or the traditional way, extracts it for us, but only if parsing succeeds. If parsing fails, there is no good option. No matter which parser we pick, it'll be the wrong one for some arguments, and the error reporting will be confusing. Fortunately, the traditional parser accepts *anything* when called in a certain way. This maximizes our chance to extract the value of "type", and in turn minimizes the risk of confusing error reporting.

2022-10-28qapi: net: introduce a way to bypass qemu_opts_parse_noisily()Laurent Vivier
As qemu_opts_parse_noisily() flattens the QAPI structures ("type" field of Netdev structure can collides with "type" field of SocketAddress), we introduce a way to bypass qemu_opts_parse_noisily() and use directly visit_type_Netdev() to parse the backend parameters. More details from Markus: qemu_init() passes the argument of -netdev, -nic, and -net to net_client_parse(). net_client_parse() parses with qemu_opts_parse_noisily(), passing QemuOptsList qemu_netdev_opts for -netdev, qemu_nic_opts for -nic, and qemu_net_opts for -net. Their desc[] are all empty, which means any keys are accepted. The result of the parse (a QemuOpts) is stored in the QemuOptsList. Note that QemuOpts is flat by design. In some places, we layer non-flat on top using dotted keys convention, but not here. net_init_clients() iterates over the stored QemuOpts, and passes them to net_init_netdev(), net_param_nic(), or net_init_client(), respectively. These functions pass the QemuOpts to net_client_init(). They also do other things with the QemuOpts, which we can ignore here. net_client_init() uses the opts visitor to convert the (flat) QemOpts to a (non-flat) QAPI object Netdev. Netdev is also the argument of QMP command netdev_add. The opts visitor was an early attempt to support QAPI in (QemuOpts-based) CLI. It restricts QAPI types to a certain shape; see commit eb7ee2cbeb "qapi: introduce OptsVisitor". A more modern way to support QAPI is qobject_input_visitor_new_str(). It uses keyval_parse() instead of QemuOpts for KEY=VALUE,... syntax, and it also supports JSON syntax. The former isn't quite as expressive as JSON, but it's a lot closer than QemuOpts + opts visitor. This commit paves the way to use of the modern way instead.

2022-10-28net: improve error message for missing netdev backendDaniel P. Berrangé
The current message when using '-net user...' with SLIRP disabled at compile time is: qemu-system-x86_64: -net user: Parameter 'type' expects a net backend type (maybe it is not compiled into this binary) An observation is that we're using the 'netdev->type' field here which is an enum value, produced after QAPI has converted from its string form. IOW, at this point in the code, we know that the user's specified type name was a valid network backend. The only possible scenario that can make the backend init function be NULL, is if support for that backend was disabled at build time. Given this, we don't need to caveat our error message with a 'maybe' hint, we can be totally explicit. The use of QERR_INVALID_PARAMETER_VALUE doesn't really lend itself to user friendly error message text. Since this is not used to set a specific QAPI error class, we can simply stop using this pre-formatted error text and provide something better. Thus the new message is: qemu-system-x86_64: -net user: network backend 'user' is not compiled into this binary The case of passing 'hubport' for -net is also given a message reminding people they should have used -netdev/-nic instead, as this backend type is only valid for the modern syntax.

2022-10-28virtio-net: fix TX timer with tx_burstLaurent Vivier
When virtio_net_flush_tx() reaches the tx_burst value all the queue is not flushed and nothing restart the timer. Fix that by doing for TX timer as we do for bottom half TX: rearming the timer if we find any packet to send during the virtio_net_flush_tx() call.

2022-10-28virtio-net: fix bottom-half packet TX on asynchronous completionLaurent Vivier
When virtio-net is used with the socket netdev backend, the backend can be busy and not able to collect new packets. In this case, net_socket_receive() returns 0 and registers a poll function to detect when the socket is ready again. In virtio_net_tx_bh(), virtio_net_flush_tx() forwards the 0, the virtio notifications are disabled and the function is not re-scheduled, waiting for the backend to be ready. When the socket netdev backend is again able to send packets, the poll function re-starts to flush remaining packets. This is done by calling virtio_net_tx_complete(). It re-enables notifications and calls again virtio_net_flush_tx(). But it seems if virtio_net_flush_tx() reaches the tx_burst value all the queue is not flushed and no new notification is sent to re-schedule virtio_net_tx_bh(). Nothing re-start to flush the queue and remaining packets are stuck in the queue. To fix that, detect in virtio_net_tx_complete() if virtio_net_flush_tx() has been stopped by tx_burst and if yes re-schedule the bottom half function virtio_net_tx_bh() to flush the remaining packets. This is what is done in virtio_net_tx_bh() when the virtio_net_flush_tx() is synchronous, and completly by-passed when the operation needs to be asynchronous.
