2015-02-26QemuOpts: Drop qemu_opt_set(), rename qemu_opt_set_err(), fix useMarkus Armbruster
qemu_opt_set() is a wrapper around qemu_opt_set() that reports the error with qerror_report_err(). Most of its users assume the function can't fail. Make them use qemu_opt_set_err() with &error_abort, so that should the assumption ever break, it'll break noisily. Just two users remain, in util/qemu-config.c. Switch them to qemu_opt_set_err() as well, then rename qemu_opt_set_err() to qemu_opt_set(). Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>
2015-02-26QemuOpts: Convert qemu_opts_set() to Error, fix its useMarkus Armbruster
Return the Error object instead of reporting it with qerror_report_err(). Change callers that assume the function can't fail to pass &error_abort, so that should the assumption ever break, it'll break noisily. Turns out all callers outside its unit test assume that. We could drop the Error ** argument, but that would make the interface less regular, so don't. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>

2014-09-04net: Forbid dealing with packets when VM is not runningzhanghailiang
For all NICs(except virtio-net) emulated by qemu, Such as e1000, rtl8139, pcnet and ne2k_pci, Qemu can still receive packets when VM is not running. If this happened in *migration's* last PAUSE VM stage, but before the end of the migration, the new receiving packets will possibly dirty parts of RAM which has been cached in *iovec*(will be sent asynchronously) and dirty parts of new RAM which will be missed. This will lead serious network fault in VM. To avoid this, we forbid receiving packets in generic net code when VM is not running. Bug reproduction steps: (1) Start a VM which configured at least one NIC (2) In VM, open several Terminal and do *Ping IP -i 0.1* (3) Migrate the VM repeatedly between two Hosts And the *PING* command in VM will very likely fail with message: 'Destination HOST Unreachable', the NIC in VM will stay unavailable unless you run 'service network restart' Signed-off-by: zhanghailiang <zhang.zhanghailiang@huawei.com> Reviewed-by: Jason Wang <jasowang@redhat.com> Reviewed-by: Juan Quintela <quintela@redhat.com> Reviewed-by: Michael S.

2014-02-25net: remove implicit peer from offload APIStefan Hajnoczi
The virtio_net offload APIs are used on the NIC's peer (i.e. the tap device). The API was defined to implicitly use nc->peer, saving the caller the trouble. This wasn't ideal because: 1. There are callers who have the peer but not the NIC. Currently they are forced to bypass the API and access peer->info->... directly. 2. The rest of the net.h API uses nc, not nc->peer, so it is inconsistent. This patch pushes nc->peer back up to callers. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2013-12-09net: Update netdev peer on link changeVlad Yasevich
When a link change occurs on a backend (like tap), we currently do not propage such change to the nic. As a result, when someone turns off a link on a tap device, for instance, then a guest doesn't see that change and continues to try to send traffic or run DHCP even though the lower-layer is disconnected. This is OK when the network is set up as a HUB since the the guest may be connected to other HUB ports too, but when it's set up as a netdev, it makes thinkgs worse. The patch addresses this by setting the peers link down only when the peer is not a HUBPORT device. With this patch, in the following config -netdev tap,id=net0 -device e1000,mac=XXXXX,netdev=net0 when net0 link is turned off, the guest e1000 shows lower-layer link down. This allows guests to boot much faster in such configurations. With windows guest, it also allows the network to recover properly since windows will not configure the link-local IPv4 address, and when the link is turned on, the proper address address is configured.

2013-12-09net: Adding netmap network backendVincenzo Maffione
This patch adds support for a network backend based on netmap. netmap is a framework for high speed packet I/O. You can use it to build extremely fast traffic generators, monitors, software switches or network middleboxes. Its companion software switch VALE lets you interconnect virtual machines. netmap and VALE are implemented as a non-intrusive kernel module, support NICs from multiple vendors, are part of standard FreeBSD distributions and available in source format for Linux too. To compile QEMU with netmap support, use the following configure options: ./configure [...] --enable-netmap --extra-cflags=-I/path/to/netmap/sys where "/path/to/netmap" contains the netmap source code, available at http://info.iet.unipi.it/~luigi/netmap/ The same webpage contains more information about the netmap project (together with papers and presentations).

2013-07-15net: add support of mac-programming over macvtap in QEMU sideAmos Kong
Currently macvtap based macvlan device is working in promiscuous mode, we want to implement mac-programming over macvtap through Libvirt for better performance. Design: QEMU notifies Libvirt when rx-filter config is changed in guest, then Libvirt query the rx-filter information by a monitor command, and sync the change to macvtap device. Related rx-filter config of the nic contains main mac, rx-mode items and vlan table. This patch adds a QMP event to notify management of rx-filter change, and adds a monitor command for management to query rx-filter information. Test: If we repeatedly add/remove vlan, and change macaddr of vlan interfaces in guest by a loop script. Result: The events will flood the QMP client(management), management takes too much resource to process the events. Event_throttle API (set rate to 1 ms) can avoid the events to flood QMP client, but it could cause an unexpected delay (~1ms), guests guests normally expect rx-filter updates immediately. So we use a flag for each nic to avoid events flooding, the event is emitted once until the query command is executed. The flag implementation could not introduce unexpected delay. There maybe exist an uncontrollable delay if we let Libvirt do the real change, guests normally expect rx-filter updates immediately. But it's another separate issue, we can investigate it when the work in Libvirt side is done. Michael S. Tsirkin: tweaked to enable events on start Michael S.

Socket buffer sizes were hard-coded to 4K for VDE and socket netdevs. Bump this up to 68K (ala tap netdev) to handle maximum GSO packet size (64k) plus plenty of room for the ethernet and virtio_net headers. Originally, ran into this limitation when using -netdev UDP sockets to connect VM-to-VM, where VM interface is configure with MTU=9000. (Using virtio_net NIC model). Test is simple: ping -M do -s 8500 <target>. This test will attempt to ping with unfragmented packet of given size. Without patch, size is limited to < 4K (minus protocol hdrs). With patch, ping test works with pkt size up to 9000 (again, minus protocol hdrs). v2: per Stefan, increase buf size to (4096+65536) as done in tap and apply to vde and socket netdevs. v1: increase buf size to 12K just for -netdev UDP sockets Signed-off-by: Scott Feldman <sfeldma@cumulusnetworks.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

1ceef9f27359cbe92ef124bf74de6f792e71f6fb added handling for cleaning up multiple queues in qemu_del_nic() for cases where multiqueue is in use. To determine the number of queues it looks at nic->conf->queues, then iterates through all the queues to cleanup the associated NetClientStates. If no queues are found, no NetClientStates are deleted. However, nic->conf->queues is only set when a peer is created via -netdev or netdev_add, and is otherwise 0. This causes us to spin in net_cleanup() if we attempt to shut down qemu before adding a host device. Since qemu_new_nic() unconditionally creates at least 1 queue/NetClientState at queue idx 0, make qemu_del_nic() always attempt to clean it up.

2013-02-01net: multiqueue supportJason Wang
This patch adds basic multiqueue support for qemu. The idea is simple, an array of NetClientStates were introduced in NICState, parse_netdev() were extended to find and match all NetClientStates belongs to the backend and place their pointers in NICConf. Then qemu_new_nic can setup a N:N mapping between NICStates that belongs to a nic and NICStates belongs to the netdev. And a queue_index were introduced in NetClientState to track its index. After this, each peers of a NICState were abstracted as a queue. After this change, all NetClientState that belongs to the same backend/nic has the same id. When use want to change the link status, all NetClientStates that belongs to the same backend/nic will be also changed. When user want to delete a device or netdev, all NetClientStates that belongs to the same backend/nic will be deleted also. Changing or deleting an specific queue is not allowed.
