[libvirt] [PATCH v4 00/29] network: refactor to decouple virt drivers from network driver
An update to v1: https://www.redhat.com/archives/libvir-list/2018-December/msg00681.html v2: https://www.redhat.com/archives/libvir-list/2019-February/msg01581.html v3: https://www.redhat.com/archives/libvir-list/2019-March/msg01259.html Currently the network driver registers a set of callbacks with the virt driver in order to handle allocating/releasing network ports associated with guest NICs. This series introduces a virNetworkPortPtr object and associated XML that describes a network port. The virt drivers now call public APIs associated with this new object to create/delete ports for guest NICs. Changed in 4: - Merged the ACKd patches which didn't depend on other un-acked parts - Improve bandwidth error messages - Ensure we set floor sum to zero when starting network - Misc fixes for previous review comments NB, I have not added missing docs for the new XML doc format yet. This is work in progress. Changed in v3: - Remove unused API symbol - Fix dist of test data files Changed in v2: - Fix many bugs related to upgrades with running VMs - Convert over bandwidth controls to the new APIs - Handle reconnecting VIFs to bridges during startup - Much much more that I can't remember Daniel P. Berrangé (29): network: ensure floor sum is reset to zero when starting networks network: explain reason for bandwidth floor rejection conf: don't pass interface type into virNetDevBandwidthParse network: use 'bridge' as actual type instead of 'network' virt drivers: don't handle type=network after resolving actual network type network: move re-attach of bridge device out of network driver network: move fixup for domain actual net def out of network driver conf: introduce virNetworkPortDefPtr struct and XML support network: make networkLogAllocation independent of domain conf conf: add APIs to convert virDomainNetDef to virNetworkPortDef network: convert networkAllocateActualDevice to virNetworkPortDef network: convert networkNotifyActualDevice to virNetworkPortDef network: convert networkReleaseActualDevice to virNetworkPortDef network: convert hook script to take a network port XML network: remove the virDomainNetBandwidthChangeAllowed callback network: introduce networkAllocatePort network: introduce networkNotifyPort network: introduce networkReleasePort network: introduce networkUpdatePortBandwidth network: add public APIs for network port object access: add permissions for network port objects remote: add support for new network port APIs virsh: add support for network port APIs conf: support recording ports against virNetworkObjPtr network: add implementation of network port APIs lxc, libxl: notify network driver of NICs during reconnect lxc, libxl: save domain status after reconnect conf: record a portid against the domain conf conf: switch over to use network port APIs for virt drivers docs/formatdomain.html.in | 8 + docs/hooks.html.in | 24 +- docs/schemas/domaincommon.rng | 5 + include/libvirt/libvirt-network.h | 122 ++ include/libvirt/virterror.h | 3 + src/access/genpolkit.pl | 2 +- src/access/viraccessdriver.h | 6 + src/access/viraccessdrivernop.c | 11 + src/access/viraccessdriverpolkit.c | 26 + src/access/viraccessdriverstack.c | 25 + src/access/viraccessmanager.c | 16 + src/access/viraccessmanager.h | 6 + src/access/viraccessperm.c | 6 + src/access/viraccessperm.h | 44 + src/conf/Makefile.inc.am | 2 + src/conf/domain_conf.c | 549 +++++++- src/conf/domain_conf.h | 49 +- src/conf/netdev_bandwidth_conf.c | 22 +- src/conf/netdev_bandwidth_conf.h | 2 +- src/conf/network_conf.c | 4 +- src/conf/virnetworkobj.c | 303 ++++ src/conf/virnetworkobj.h | 34 + src/conf/virnetworkportdef.c | 515 +++++++ src/conf/virnetworkportdef.h | 112 ++ src/datatypes.c | 60 + src/datatypes.h | 41 + src/driver-network.h | 41 + src/libvirt-network.c | 444 ++++++ src/libvirt_private.syms | 23 +- src/libvirt_public.syms | 15 + src/libxl/libxl_conf.c | 21 +- src/libxl/libxl_driver.c | 33 + src/lxc/lxc_driver.c | 15 +- src/lxc/lxc_process.c | 35 + src/network/bridge_driver.c | 1219 +++++++++-------- src/qemu/qemu_command.c | 8 +- src/qemu/qemu_driver.c | 10 +- src/qemu/qemu_hotplug.c | 13 +- src/qemu/qemu_interface.c | 12 +- src/qemu/qemu_process.c | 5 +- src/remote/remote_daemon_dispatch.c | 73 + src/remote/remote_driver.c | 69 + src/remote/remote_protocol.x | 124 +- src/remote_protocol-structs | 69 + src/rpc/gendispatch.pl | 18 +- src/util/virerror.c | 9 + src/util/virhook.c | 4 +- src/util/virhook.h | 4 +- tests/Makefile.am | 7 + .../net-virtio-network-portgroup.xml | 6 +- tests/virnetdevbandwidthtest.c | 2 +- .../plug-bridge-mactbl.xml | 9 + .../virnetworkportxml2xmldata/plug-bridge.xml | 12 + .../virnetworkportxml2xmldata/plug-direct.xml | 12 + .../plug-hostdev-pci.xml | 12 + tests/virnetworkportxml2xmldata/plug-none.xml | 8 + tests/virnetworkportxml2xmltest.c | 104 ++ tools/virsh-completer.c | 50 + tools/virsh-completer.h | 4 + tools/virsh-network.c | 399 +++++- tools/virsh-network.h | 5 + 61 files changed, 4171 insertions(+), 720 deletions(-) create mode 100644 src/conf/virnetworkportdef.c create mode 100644 src/conf/virnetworkportdef.h create mode 100644 tests/virnetworkportxml2xmldata/plug-bridge-mactbl.xml create mode 100644 tests/virnetworkportxml2xmldata/plug-bridge.xml create mode 100644 tests/virnetworkportxml2xmldata/plug-direct.xml create mode 100644 tests/virnetworkportxml2xmldata/plug-hostdev-pci.xml create mode 100644 tests/virnetworkportxml2xmldata/plug-none.xml create mode 100644 tests/virnetworkportxml2xmltest.c -- 2.20.1
In extreme cases libvirt can get mixed up about what VMs are running and attached to a network leading to the cached floor sum value being outdated. When this happens the only option is to destroy the network and then restart libvirtd. If we set floor sum back to zero when starting the network, we avoid the need for a libvirtd restart at least.

The virNetDevBandwidthParse method uses the interface type to decide whether to allow use of the "floor" parameter. Using the interface type is not convenient as callers may not have that available, but still wish to allow use of "floor". Switch to an explicit boolean to control its usage.

I think this is a bug, but even if it is, it is pre-existing. (The bandwidth in a <portgroup> should be applied to any interface tagged with that portgroup, i.e. it's not an attribute that's set for the entire network, but for just one interface. So iiuc, allowFloor should be true if the network is one that uses a routed connection (forward mode route/nat/none))

Well sort of. If using a plain bridge virtual network you can't use floor - that's only valid for routed networks. Trying to enforce this at parse time is doomed though - you can only corrrectly report this at runtime as you need the context of the virtual network itself. This was already an issue when parsing the top level netdef - only the actual netdef had any better checking. I'm almost inclined to remove all the logic preventing "floor" at XML parse time and rely on runtime checks entirely.

Except that the same parse function is used for the <bandwidth> element in <network>, which never allows floor to be set. For the <bandwidth> in an interface though, you're correct that it's impossible to know beforehand.

I was thinking in terms of making it still correct in the "new world order" where actual->type will always be bridge rather than network. But then later I saw that this line is removed in the next patch anyway, so it's kind of irrelevant - for the state of everything at the point of *this* patch, the two are equivalent.
Ports allocated on virtual networks with type=nat|route|open all get given an actual type of 'network'. Only ports in networks with type=bridge use an actual type of 'bridge'.

Yeah, I don't remember if there was an operational difference between the two in the past (other than bandwidth floor) or if I just made the distinction because I was concerned that there *might be*, but definitely it's something that needs to go! (Heck, maybe there *still* is a reason for differentiating, but even if there is we should still be able to look at the config of the network itself to learn the necessary details).
This doesn't affect user visible XML since the "actual" device XML is internal only, but we need code to convert the data upgrades.
This does mean that downgrades will create "strange situations". Nothing horribly bad, but worth remembering for future reference.

It looks like git was confused here during a rebase, and it merged the code into the wrong function - this patch puts it into virDomainDiskDefPostParse(), but I'm guessing it should go in virDomainNetDefPostParse() (moving it there certainly gets it to compile properly at least :-) (NB: once several years ago git merged a chunk into the wrong function and I learned that (at that time, hopefully it's changed since) git ignored the name of the function listed just after the line number info at the top of each chunk).

Instead, any "status" item that could *ever* possibly differ from a similar "transient config" item should have its own distinct read-only attribute/element in the XML.

It will be more complicated that just reading the domain XML a single time, but at least it will allow us to learn status info distinct from transient config.

Doesn't it all come down to the fact that the status XML now has "bridge" instead of "network"? Maybe if we make a patch to change *only* what is put in the externally visible status XML, but internally (and in the <actual> element of the status that's stored on disk) maintain the change from "network" to "bridge"? I can try making a patch like that.
Should we revert this?
If we can't do something to get these virsh commands working before the release, then I think we'll have to.

Maybe if we make a patch to change *only* what is put in the externally visible status XML, but internally (and in the <actual> element of the status that's stored on disk) maintain the change from "network" to "bridge"? I can try making a patch like that.
Double Ugh. Not so easy as I'd assumed :-( The problem is that we can't just fix it by always putting the type from the config in the XML - if the config type is "network" and the network has a forward mode that uses IP routing to forward packets then the type stays at "network", but if the network has any other forward mode, then the status XML shows the actual type (bridge, direct, hostdev). Essentially, the forward mode of the network is encoded into the "actual type" of the interface, and it's not available from anywhere else at the time we format the status XML, so we can't "internally change the type, but format 'what we would have set the type to in the past' when we're creating the XML document to output. I *would like to say* that putting the actual type in the status XML at all is an error, and should be fixed. But it's been that way for nearly 5 years now, and changing it might break something else. Also, the actual type (i.e. status of the interface) isn't available from anywhere else. So my brain is kind of stuck on what is the right thing to do.
Should we revert this?
If we can't do something to get these virsh commands working before the release, then I think we'll have to.
In order to preserve compatibility with old virsh, I think we need to keep the interface type as it previously was in the status XML. On the other hand, the way it was is just... bad. Not only does it make it impossible to do a "read transient config. modify, update transient config" of an interface, it is encoding multiple things into a single attribute. (*This* is a great example of why I always worry excessively over any XML addition/change. For all the good it apparently does...)

Ports allocated on virtual networks with type=nat|route|open all get given an actual type of 'network'.
Only ports in networks with type=bridge use an actual type of 'bridge'.
This distinction makes little sense since the virtualization drivers will treat both actual types in exactly the same way, as they're all just bridge devices a VM needs to be connected to.
This doesn't affect user visible XML since the "actual" device XML is internal only, but we need code to convert the data upgrades.

Actually, this breaks a lot of stuff. Firstly, for a live XML the type is changed to <interface type='bridge'> .. </interface>. This is because virDomainNetDefFormat() decides to format actual info.
Urgh this is a real pain point & really a regression. I believed the comments that the Actual def was internal only and not visible to users. I think this alone makes a revert necceessary and probably meansI have to abandon this idea completely :-(
Having said that, transitionally some APIs are broken too. For instance, I have the following interface for my domain (inactive XML):
<interface type='network' trustGuestRxFilters='yes'> <mac address='52:54:00:a4:6f:91'/> <source network='default'/> <bandwidth> <inbound average='1024' peak='4096' floor='500' burst='1024'/> <outbound average='10240'/> </bandwidth> <model type='virtio'/> <mtu size='9000'/> </interface>
Now, 'virsh domif-setlink', 'virsh update-device', 'virsh domiftune' don't work, because at runtime type is changed to 'bridge' and we don't implement many features for that network type.
I'll post patches for the first two issues I've found. But they look pretty hacky and I'm not sure my testing was exhaustive enough to find other cases where this will break. The third one I have no idea how to fix because it boils down to looking a network in the bridge driver but we don't know the network name because we don't parse it for interface type bridge.
Should we revert this?
I think reverting is going to be the easiest, certainly for this imminent release.

The call to resolve the actual network type will turn any NICs with type=network into one of the other types. Thus there should be no need to handle type=network in later switch() statements jumping off the actual type. Reviewed-by: Cole Robinson <crobinso@redhat.com> Signed-off-by: Daniel P.

When (un)plugging an interface into a network, the 'plugged' and 'unplugged' operations are invoked in the hook script. The data provided to the script contains the network XML, the domain XML and the domain interface XML. When we strictly split the drivers up this will no longer be possible and thus breakage is unavoidable. The hook scripts are not considered to be covered by the API guarantee so this is OK. To avoid existing scripts taking the wrong action, the existing operations are changed to 'port-created' and 'port-deleted' instead. These will receive the network XML and the network port XML.

The current qemu driver code for changing bandwidth on a NIC first asks the network driver if the change is supported, then changes the bandwidth on the VIF, and then tells the network driver to update the bandwidth on the bridge. This is potentially racing if a parallel API call causes the network driver to allocate bandwidth on the bridge between the check and the update phases. Change the code to just try to apply the network bridge update immediately and rollback at the end if something failed. Reviewed-by: Laine Stump <laine@laine.org> Signed-off-by: Daniel P.
