qapi: net: add stream and dgram netdevs 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.

net: Allow hubports to connect to other netdevs QEMU can emulate hubs to connect NICs and netdevs. This is currently primarily used for the mis-named 'vlan' feature of the networking subsystem. Now the 'vlan' feature has been marked as deprecated, since its name is rather confusing and the users often rather mis-configure their network when trying to use it. But while the 'vlan' parameter should be removed at one point in time, the basic idea of emulating a hub in QEMU is still good: It's useful for bundling up the output of multiple NICs into one single l2tp netdev for example. Now to be able to use the hubport feature without 'vlan's, there is one missing piece: The possibility to connect a hubport to a netdev, too. This patch adds this possibility by introducing a new "netdev=..." parameter to the hubports. To bundle up the output of multiple NICs into one socket netdev, you can now run QEMU with these parameters for example: qemu-system-ppc64 ... -netdev socket,id=s1,connect=:11122 \ -netdev hubport,hubid=1,id=h1,netdev=s1 \ -netdev hubport,hubid=1,id=h2 -device e1000,netdev=h2 \ -netdev hubport,hubid=1,id=h3 -device virtio-net-pci,netdev=h3 For using the socket netdev, you have got to start another QEMU as the receiving side first, for example with network dumping enabled: qemu-system-x86_64 -M isapc -netdev socket,id=s0,listen=:11122 \ -device ne2k_isa,netdev=s0 \ -object filter-dump,id=f1,netdev=s0,file=/tmp/dump.dat After the ppc64 guest tried to boot from both NICs, you can see in the dump file (using Wireshark, for example), that the output of both NICs (the e1000 and the virtio-net-pci) has been successfully transfered via the socket netdev in this case.

qapi: net: add stream and dgram netdevs 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.
