Currently, if scrub (used for wiping algorithms) is not present
at compile time, we don't support any other wiping algorithms than
zeroing, even if it was installed later. Switch to runtime detection
instead.

Commit 7033c5f2 introduced some bugs in polkit0 authentication.

Fix libvirtd segfault in remoteDispatchAuthPolkit().

Fix polkit authentication bypass when caller UID = 0.

Commit 8dd623b9 introduced a build error with --enable-compile-warnings=error

  remote.c:2593: error: unused variable 'rv' [-Wunused-variable]

Pushing under build-breaker rule.

The v4 patch corrects indentation issues.

The v3 patch follows latest python binding codes and change 'size'
type from int to Py_ssize_t.

An simple example to show how to use it:

#!/usr/bin/env python

import libvirt

conn = libvirt.open(None)
dom = conn.lookupByName('foo')

print dom.interfaceParameters('vnet0', 0)

params = {'outbound.peak': 10,
          'inbound.peak': 10,
          'inbound.burst': 20,
          'inbound.average': 20,
          'outbound.average': 30,
          'outbound.burst': 30}

print dom.setInterfaceParameters('vnet0', params, 0)
print dom.interfaceParameters('vnet0', 0)

Bug introduced in commit 35abced2.  On an inactive domain,
$ virsh snapshot-create-as dom snap
$ virsh snapshot-create dom
$ virsh snapshot-create dom
$ virsh snapshot-delete --children dom snap
could crash libvirtd, due to a use-after-free that results
when the callback freed the current element in the iteration.

* src/conf/domain_conf.c (virDomainSnapshotForEachChild)
(virDomainSnapshotActOnDescendant): Allow iteration to delete
current child.

Regression introduced in commit 7033c5f2, due to improper conversion
from snprintf to virAsprintf.

* daemon/remote.c (remoteDispatchAuthList): Check return value
correctly.

Leak introduced in commit bb2eddc6.

* daemon/remote.c (remoteDispatchAuthPolkit): Also free pkout on
success.

This patch allows libvirt to add interfaces to already
existing Open vSwitch bridges. The following syntax in
domain XML file can be used:

    <interface type='bridge'>
      <mac address='52:54:00:d0:3f:f2'/>
      <source bridge='ovsbr'/>
      <virtualport type='openvswitch'>
        <parameters interfaceid='921a80cd-e6de-5a2e-db9c-ab27f15a6e1d'/>
      </virtualport>
      <address type='pci' domain='0x0000' bus='0x00'
                          slot='0x03' function='0x0'/>
    </interface>

or if libvirt should auto-generate the interfaceid use
following syntax:

    <interface type='bridge'>
      <mac address='52:54:00:d0:3f:f2'/>
      <source bridge='ovsbr'/>
      <virtualport type='openvswitch'>
      </virtualport>
      <address type='pci' domain='0x0000' bus='0x00'
                          slot='0x03' function='0x0'/>
    </interface>

It is also possible to pass an optional profileid. To do that
use following syntax:

   <interface type='bridge'>
     <source bridge='ovsbr'/>
     <mac address='00:55:1a:65:a2:8d'/>
     <virtualport type='openvswitch'>
       <parameters interfaceid='921a80cd-e6de-5a2e-db9c-ab27f15a6e1d'
                   profileid='test-profile'/>
     </virtualport>
   </interface>

To create Open vSwitch bridge install Open vSwitch and
run the following command:

    ovs-vsctl add-br ovsbr

An upcoming patch will add a <virtualport> element to interfaces of
type='bridge', so it makes sense to give this function a more generic
name.

The current default method of terminating the qemu process is to send
a SIGTERM, wait for up to 1.6 seconds for it to cleanly shutdown, then
send a SIGKILL and wait for up to 1.4 seconds more for the process to
terminate. This is problematic because occasionally 1.6 seconds is not
long enough for the qemu process to flush its disk buffers, so the
guest's disk ends up in an inconsistent state.

Since this only occasionally happens when the timeout prior to SIGKILL
is 1.6 seconds, this patch increases that timeout to 10 seconds. At
the very least, this should reduce the occurrence from "occasionally"
to "extremely rarely". (Once SIGKILL is sent, it waits another 5
seconds for the process to die before returning).

Note that in the cases where it takes less than this for qemu to
shutdown cleanly, libvirt will *not* wait for any longer than it would
without this patch - qemuProcessKill polls the process and returns as
soon as it is gone.

This patch is based on an earlier patch by Eric Blake which was never
committed:

https://www.redhat.com/archives/libvir-list/2011-November/msg00243.html

Aside from rebasing, this patch only drops the driver lock once (prior
to the first time the function sleeps), then leaves it dropped until
it returns (Eric's patch would drop and re-acquire the lock around
each call to sleep).

At the time Eric sent his patch, the response (from Dan Berrange) was
that, while it wasn't a good thing to be holding the driver lock while
sleeping, we really need to rethink locking wrt the driver object,
switching to a finer-grained approach that locks individual items
within the driver object separately to allow for greater concurrency.

This is a good plan, and at the time it made sense to not apply the
patch because there was no known bug related to the driver lock being
held in this function.

However, we now know that the length of the wait in qemuProcessKill is
sometimes too short to allow the qemu process to fully flush its disk
cache before SIGKILL is sent, so we need to lengthen the timeout (in
order to improve the situation with management applications until they
can be updated to use the new VIR_DOMAIN_DESTROY_GRACEFUL flag added
in commit 72f8a7f1). But, if we
lengthen the timeout, we also lengthen the amount of time that all
other threads in libvirtd are essentially blocked from doing anything
(since just about everything needs to acquire the driver lock, if only
for long enough to get a pointer to a domain).

The solution is to modify qemuProcessKill to drop the driver lock
while sleeping, as proposed in Eric's patch. Then we can increase the
timeout with a clear conscience, and thus at least lower the chances
that someone running with existing management software will suffer the
consequence's of qemu's disk cache not being flushed.

In the meantime, we still should work on Dan's proposal to make
locking within the driver object more fine grained.

(NB: although I couldn't find any instance where qemuProcessKill() was
called with no jobs active for the domain (or some other guarantee
that the current thread had at least one refcount on the domain
object), this patch still follows Eric's method of temporarily adding
a ref prior to unlocking the domain object, because I couldn't
convince myself 100% that this was the case.)

* libvirt.pc.in: Add missing '/api/' in path
* libvirt.spec.in, mingw32-libvirt.spec.in: s/apis/api/

via user agent. Allow targets mem & hybrid iff system_wakeup
monitor command is available.

In the future (my next patch in fact) we may want to make
decisions depending on qemu having a monitor command or not.
Therefore, we want to set qemuCaps flag instead of querying
on the monitor each time we are about to make that decision.

Language bindings may well want to use the libvirt-api.xml and
libvirt-qemu-api.xml files to either auto-generate themselves,
or sanity check the manually written bindings for completeness.
Currently these XML files are not installed as standard, merely
ending up as a %doc file in the RPM.

This changes them to be installed into $prefix/share/libvirt/apis/
The *-refs.xml files are not installed, since those are only
useful during generation of the online API doc files.

The pkg-config file is enhanced so that you can query the install
location of the API files. eg

  # pkg-config --variable=libvirt_qemu_api libvirt
  /home/berrange/builder/i686-pc-mingw32/sys-root/mingw/share/libvirt/libvirt-qemu-api.xml

* docs/Makefile.am: Install libvirt-api.xml & libvirt-qemu-api.xml
* libvirt.pc.in: Add vars for querying API install location
* libvirt.spec.in, mingw32-libvirt.spec.in: Include API XML files

When blkdeviotune was first committed in 0.9.8, we had the limitation
that setting one value reset all others.  But bytes and iops should
be relatively independent.  Furthermore, setting tuning values on
a live domain followed by dumpxml did not output the new settings.

* src/qemu/qemu_driver.c (qemuDiskPathToAlias): Add parameter, and
update callers.
(qemuDomainSetBlockIoTune): Don't lose previous unrelated
settings.  Make live changes reflect to dumpxml output.
* tools/virsh.pod (blkdeviotune): Update documentation.

* configure.ac docs/news.html.in libvirt.spec.in: updated for the release
* po/*.po*: update ja, it and uk localization, fixed the ja one

Replace calls to fwrite() and fscanf() with more portable-friendly

The auto-generated WWN comply with the new addressing schema of WWN:

<quote>
the first nibble is either hex 5 or 6 followed by a 3-byte vendor
identifier and 36 bits for a vendor-specified serial number.
</quote>

We choose hex 5 for the first nibble. And for the 3-bytes vendor ID,
we uses the OUI according to underlying hypervisor type, (invoking
virConnectGetType to get the virt type). e.g. If virConnectGetType
returns "QEMU", we use Qumranet's OUI (00:1A:4A), if returns
ESX|VMWARE, we use VMWARE's OUI (00:05:69). Currently it only
supports qemu|xen|libxl|xenapi|hyperv|esx|vmware drivers. The last
36 bits are auto-generated.

Some audit records generated by libvirt contain fields enclosed by single
quotes. Since those fields are inside the msg field, which is enclosed by
single quotes, these records generated by libvirt are not correctly parsed by
libauparse.

Some tools, such as virt-manager, prefers having the default USB
controller explicit in the XML document. This patch makes sure there
is one. With this patch, it is now possible to switch from USB1 to
USB2 from the release 0.9.1 of virt-manager.

Fix tests to pass with this change.

romfile wasn't mentioned in the comment, and the fact that rombar is
now supported for network interfaces also wasn't there.

The API definition accepts "flags" argument, however, the
implementation ignores it, though "flags" is unused currently,
we should expose it instead of hard coding, the API
implementation inside hypervisor driver is responsible to check
if the passed "flags" is valid.
