2011-07-23net: Consistently use qemu_macaddr_default_if_unsetJan Kiszka1-8/+2
Drop the open-coded MAC assignment from net_init_nic and replace it with standard qemu_macaddr_default_if_unset which is also used by qdev. That avoid creating colliding MACs when instantiating NICs via different mechanisms. This change requires to store the MAC as MACAddr in NICInfo, and the remaining nd_table users need to be updated.

2011-07-19Fix netdev name lookup in -device, device_add, netdev_delMarkus Armbruster1-2/+8
qemu_find_netdev() looks up members of non_vlan_clients by name. It happily returns the first match. Trouble is the names need not be unique. non_vlan_clients contains host parts (netdevs) and guest parts (NICs). Netdevs have unique names: a netdev's name is a (mandatory) qemu_netdev_opts ID, and these are unique. NIC names are not unique. If a NIC has a qdev ID (which is unique), that's its name. Else, we make up a name. The made-up names are unique, but they can clash with qdev IDs. Even if NICs had unique names, they could still clash with netdev names. Callers of qemu_find_netdev(): * net_init_nic() wants a netdev. It happens to work because it runs before NICs get added to non_vlan_clients. * do_netdev_del() wants a netdev. If it gets a NIC, it complains and fails. Bug: a netdev with the same name that comes later in non_vlan_clients can't be deleted: $ qemu-system-x86_64 -nodefaults -vnc :0 -S -monitor stdio -netdev user,id=hostnet0 -device virtio-net-pci,netdev=hostnet0,id=virtio1 [...] (qemu) netdev_add user,id=virtio1 (qemu) info network Devices not on any VLAN: hostnet0: net=10.0.2.0, restricted=n peer=virtio1 virtio1: model=virtio-net-pci,macaddr=52:54:00:12:34:56 peer=hostnet0 virtio1: net=10.0.2.0, restricted=n (qemu) netdev_del virtio1 Device 'virtio1' not found * parse_netdev() wants a netdev. If it gets a NIC, it gets confused. With the test setup above: (qemu) device_add virtio-net-pci,netdev=virtio1 Property 'virtio-net-pci.netdev' can't take value 'virtio1', it's in use You can even connect two NICs to each other: $ qemu-system-x86_64 -nodefaults -vnc :0 -S -monitor stdio -device virtio-net-pci,id=virtio1 -device e1000,netdev=virtio1 [...] Devices not on any VLAN: virtio1: model=virtio-net-pci,macaddr=52:54:00:12:34:56 peer=e1000.0 e1000.0: model=e1000,macaddr=52:54:00:12:34:57 peer=virtio1 (qemu) q Segmentation fault (core dumped) * do_set_link() works fine for both netdevs and NICs. Whether it really makes sense for netdevs is debatable, but that's outside this patch's scope. Change qemu_find_netdev() to return only netdevs. This fixes the netdev_del and device_add/-device bugs demonstrated above. To avoid changing set_link, make do_set_link() search non_vlan_clients by hand instead of calling qemu_find_netdev(). Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Michael S.

2011-07-19Fix automatically assigned network names for netdevMarkus Armbruster1-2/+7
If a network client doesn't have a name, we make one up, with assign_name(). assign_name() creates a name MODEL.NUM, where MODEL is the client's model, and NUM is the number of MODELs that already exist. Bug: it misses clients that are not on a VLAN, i.e. netdevs and the NICs using them: $ qemu-system-x86_64 -nodefaults -vnc :0 -S -monitor stdio -netdev user,id=hostnet0 -net nic,netdev=hostnet0 -netdev user,id=hostnet1 -net nic,netdev=hostnet1 QEMU 0.14.50 monitor - type 'help' for more information (qemu) info network Devices not on any VLAN: hostnet0: net=10.0.2.0, restricted=n peer=e1000.0 hostnet1: net=10.0.2.0, restricted=n peer=e1000.0 e1000.0: model=e1000,macaddr=52:54:00:12:34:56 peer=hostnet0 e1000.0: model=e1000,macaddr=52:54:00:12:34:57 peer=hostnet1 Fix that.

2011-03-05net: fix qemu_can_send_packet logicVincent Palatin1-3/+3
If any of the clients is not ready to receive (ie it has a can_receive callback and can_receive() returns false), we don't want to start sending, else this client may miss/discard the packet. I got this behaviour with the following setup : the emulated machine is using an USB-ethernet adapter, it is connected to the network using SLIRP and I'm dumping the traffic in a .pcap file. As per the following command line : -net nic,model=usb,vlan=1 -net user,vlan=1 -net dump,vlan=1,file=/tmp/pkt.pcap Every time that two packets are coming in a row from the host, the usb-net code will receive the first one, then returns 0 to can_receive call since it has a 1 packet long queue. But as the dump code is always ready to receive, qemu_can_send_packet will return true and the next packet will discard the previous one in the usb-net code.

2011-02-20net: notify peer about link status changeMichael S. Tsirkin1-0/+11
qemu makes it possible to disable link at tap which is not communicated to the guest but causes all packets to be dropped. This works for virtio userspace, as qemu stops giving it packets, but not for virtio-net connected to vhost-net as that does not get notified about this change. Notify peer when this happens, which will then be used by the follow-up patch to stop/start vhost-net. Note: it might be a good idea to make peer link status match tap in this case, so the guest gets an event and updates the carrier state. For now stay bug for bug compatible with what we used to have in userspace. Signed-off-by: Michael S.

Add an option to specify the host IP to send multicast packets from, when using a multicast socket for networking. The option takes an IP address and sets the IP_MULTICAST_IF socket option, which causes the packets to use that IP's interface as an egress.

2010-10-06net: delay freeing peer host deviceMichael S. Tsirkin1-7/+42
With -netdev, virtio devices present offload features to guest, depending on the backend used. Thus, removing host netdev peer while guest is active leads to guest-visible inconsistency and/or crashes. As a solution, while guest (NIC) peer device exists, we prevent the host peer from being deleted. This patch does this by adding peer_deleted flag in nic state: if host device is going away while guest device is around, set this flag and keep a shell of the host device around for as long as guest device exists. The link is put down so all packets will get discarded. At the moment, management can detect that device deletion is delayed by doing info net. As a next step, we shall add commands that control hotplug/unplug without removing the device, and an event to report that guest has responded to the hotplug event. Signed-off-by: Michael S.

2010-06-30net: Fix VM start with '-net none'Amit Shah1-1/+1
Commit 50e32ea8f31035877decc10f1075aa0e619e09cb changed the behaviour for the return type of net_client_init() when a nic type with no init method was specified. 'none' is one such nic type. Instead of returning 0, which gets interpreted as an index into the nd_table[] array, we switched to returning -1, which signifies an error as well. That broke VM start with '-net none'. Testing was only done with the monitor command 'pci_add', which doesn't fail. The correct fix would still be to return 0+ values from net_client_init() only when the return value can be used as an index to refer to an entry in nd_table[]. With the current code, callers can erroneously poke into nd_table[0] when -net nic is used, which can lead to badness. However, this commit just returns to the previous behaviour before the offending commit. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-06-14Make netdev_del delete the netdev even when it's in useMarkus Armbruster1-4/+0
To hot-unplug guest and host part of a network device, you do: device_del NIC-ID netdev_del NETDEV-ID For PCI devices, device_del merely tells ACPI to unplug the device. The device goes away for real only after the guest processed the ACPI unplug event. You have to wait until then (e.g. by polling info pci) before you can unplug the netdev. Not good. Fix by removing the "in use" check from do_netdev_del(). Deleting a netdev while it's in use is safe; packets simply get routed to the bit bucket.

2010-04-10net: remove broken net_set_boot_mask() boot device validationEduardo Habkost1-19/+0
There are many problems with net_set_boot_mask(): 1) It is broken when using the device model instead of "-net nic". Example: $ qemu-system-x86_64 -device rtl8139,vlan=0,id=net0,mac=52:54:00:82:41:fd,bus=pci.0,addr=0x4 -net user,vlan=0,name=hostnet0 -vnc 0.0.0.0:0 -boot n Cannot boot from non-existent NIC $ 2) The mask was previously used to set which boot ROMs were supposed to be loaded, but this was changed long time ago. Now all ROM images are loaded, and SeaBIOS takes care of jumping to the right boot entry point depending on the boot settings. 3) Interpretation and validation of the boot parameter letters is done on the machine type code. Examples: PC accepts only a,b,c,d,n as valid boot device letters. mac99 accepts only a,b,c,d,e,f. As a side-effect of this change, qemu-kvm won't abort anymore if using "-boot n" on a machine with no network devices. Checking if the requested boot device is valid is now a task for the BIOS or the machine-type code.

2010-02-19net: Fix bogus "Warning: vlan 0 with no nics" with -deviceMarkus Armbruster1-7/+18
net_check_clients() prints this when an VLAN has host devices, but no guest devices. It uses VLANState members nb_guest_devs and nb_host_devs to keep track of these devices. However, -device does not update nb_guest_devs, only net_init_nic() does that, for -net nic. Check the VLAN clients directly, and remove the counters.
