When running in libvirtd, we are happy for any of the drivers to simply
skip their initialization in virStateInitialize, as other drivers are

When running in per-driver daemons though, we want the daemon to abort

In many files there are header comments that contain an Author:

In a large collaborative project like libvirt, any non-trivial

omitting people who have made significant contribitions.
In some places Author: lines have been added despite the person
merely being responsible for creating the file by moving existing

With this all in mind, the comments are useless as a means to identify
who to talk to about code in a particular file. Contributors will always

This commit thus deletes all Author: comments from the source and adds

If a system has a large number of active or active interfaces, it can
be a big waste of time to retrieve and qualify all interfaces if the
caller only wanted one subset. Since netcf has a simple flag for this,
translate the libvirt flag into a netcf flag and let netcf pre-filter.
Getting the MAC address of an interface is actually fairly expensive,
and we've already gotten it and stored it into def, so just keep def
around a bit longer and retrieve it from there.
This reduces the time for "virsh iface-list --all" from 28 to 23
seconds when there are 400 interfaces.
The spec for virConnectListAllInterfaces says that if the pointer that
is supposed to hold the list of interfaces is NULL, the function
should just return the count of interfaces that matched the filter,
but the code never increments the count if the list pointer is NULL.
For stateless, client side drivers, it is never correct to
probe for secondary drivers. It is only ever appropriate to
use the secondary driver that is associated with the
hypervisor in question. As a result the ESX & HyperV drivers
have both been forced to do hacks where they register no-op
drivers for the ones they don't implement.
For stateful, server side drivers, we always just want to
use the same built-in shared driver. The exception is
virtualbox which is really a stateless driver and so wants
to use its own server side secondary drivers. To deal with
this virtualbox has to be built as 3 separate loadable
modules to allow registration to work in the right order.
This can all be simplified by introducing a new struct
recording the precise set of secondary drivers each
hypervisor driver wants
struct _virConnectDriver {
virHypervisorDriverPtr hypervisorDriver;
virInterfaceDriverPtr interfaceDriver;
virNetworkDriverPtr networkDriver;
virNodeDeviceDriverPtr nodeDeviceDriver;
virNWFilterDriverPtr nwfilterDriver;
virSecretDriverPtr secretDriver;
virStorageDriverPtr storageDriver;
};
Instead of registering the hypervisor driver, we now
just register a virConnectDriver instead. This allows
us to remove all probing of secondary drivers. Once we
have chosen the primary driver, we immediately know the
correct secondary drivers to use.

Other drivers in libvirt (e.g. network, qemu) will automatically
return the "inactive" (persistent configuration) XML of an object when
that object is inactive. The netcf backend of the interface driver
would always try to return the live status XML of the interface, even
when it was down. Although netcf does return valid XML in that case,
for bond interfaces it is missing almost all of its content, including
the <bond> subelement itself, leading to this error message from
"virsh iface-dumpxml" of a bond interface that is inactive:
error: XML error: bond interface misses the bond element
(this is because libvirt's validation of the XML returned by netcf
always requires a <bond> element be present).
This patch modifies the interface driver netcf backend to check if the
interface is inactive, and in that case always return the inactive XML
(which will always have a <bond> element, thus eliminating the error
message, as well as making operation more in line with other drivers.

This resolves: https://bugzilla.redhat.com/show_bug.cgi?id=983026
The netcf interface driver previously had no state driver associated
with it - as a connection was opened, it would create a new netcf
instance just for that connection, and close it when it was
finished. the problem with this is that each connection to libvirt
used up a netlink socket, and there is a per process maximum of ~1000
netlink sockets.
The solution is to create a state driver to go along with the netcf
driver. The state driver will opens a netcf instance, then all
connections share that same netcf instance, thus only a single
netlink socket will be used no matter how many connections are mde to
libvirtd.
This was rather simple to do - a new virObjectLockable class is
created for the single driverState object, which is created in
netcfStateInitialize and contains the single netcf handle; instead of
creating a new object for each client connection, netcfInterfaceOpen
now just increments the driverState object's reference count and puts
a pointer to it into the connection's privateData. Similarly,
netcfInterfaceClose() just un-refs the driverState object (as does
netcfStateCleanup()), and virNetcfInterfaceDriverStateDispose()
handles closing the netcf instance. Since all the functions already
have locking around them, the static lock functions used by all
functions just needed to be changed to call virObjectLock() and
virObjectUnlock() instead of directly calling the virMutex* functions.
This better fits the modern naming scheme in libvirt, and anticipates
an upcoming change where a single instance of this state will be
maintained by a separate state driver, and every instance of the netcf
driver will share the same state.
Convert the type of loop iterators named 'i', 'j', k',
'ii', 'jj', 'kk', to be 'size_t' instead of 'int' or

All other backends for virInterface or other HVs implementations of
virInterface list their own names for the name instead of the generic
'Interface' value. This does the same for the netcf based backend.
Also, report any errors during registration.
Add a read-only udev based backend for virInterface. Useful for distros
that do not have netcf support yet. Multiple libvirt based utilities use
a HAL based fallback when virInterface is not available which is less
than ideal. This implements:
* virConnectNumOfInterfaces()
* virConnectListInterfaces()
* virConnectNumOfDefinedInterfaces()
* virConnectListDefinedInterfaces()
* virConnectListAllInterfaces()
* virConnectInterfaceLookupByName()
* virConnectInterfaceLookupByMACString()

* globally: s/; If/. If/
Based exclusively on work by Eric Blake in a patch posted with the same

build the driver and using WITH_NETCF to identify that we're wanting to

* src/interface/netcf_driver.c: Renamed..
* src/interface/interface_backend_netcf.c: ..to this to match storage.
* src/interface/netcf_driver.h: Renamed..
* src/interface/interface_driver.h: ..to this.
* daemon/Makefile.am: Respect WITH_INTERFACE and WITH_NETCF.
* libvirt.spec.in: Add RPM support for --with-interface
This is not that ideal as API for other objects, as it's still
O(n). Because interface driver uses netcf APIs to manage the
stuffs, instead of by itself. And netcf APIs don't return a object.
It provides APIs like old libvirt APIs:
ncf_number_of_interfaces
ncf_list_interfaces
ncf_lookup_by_name
......
Perhaps we should further improve netcf to let it provide an API
to return the object, but it could be a later patch. And anyway,
we will still benefit from the new API for the simplification,
and no race like the old APIs.

There were two API in driver.c that were silently masking flags
bits prior to calling out to the drivers, and several others
that were explicitly masking flags bits. This is not
forward-compatible - if we ever have that many flags in the
future, then talking to an old server that masks out the
flags would be indistinguishable from talking to a new server
that can honor the flag. In general, libvirt.c should forward
_all_ flags on to drivers, and only the drivers should reject
unknown flags.
In the case of virDrvSecretGetValue, the solution is to separate
the internal driver callback function to have two parameters
instead of one, with only one parameter affected by the public
API. In the case of virDomainGetXMLDesc, it turns out that
no one was ever mixing VIR_DOMAIN_XML_INTERNAL_STATUS with
the dumpxml path in the first place; that internal flag was
only used in saving and restoring state files, which happened
to be in functions internal to a single file, so there is no
mixing of the internal flag with a public flags argument.
Additionally, virDomainMemoryStats passed a flags argument
over RPC, but not to the driver.
