* docs/news.html.in libvirt.spec.in: Updated for the release
* po/*.po*: regenerated

This was originally set to 5 seconds, but times of 5.5 to 7 seconds
were experienced. Since it's an arbitrary number intended to prevent
an infinite hang, having it a bit too high won't hurt anything, and 20
seconds looks to be adequate (i.e. I think/hope we don't need to make
it tunable in libvirtd.conf)

If DAD not finished in 5 seconds, user will get an
unknown error like this:

 # virsh net-start ipv6
 error: Failed to start network ipv6
 error: An error occurred, but the cause is unknown

Call virReportError to set an error.

There has been a report on the list [1] that we are not
installing the wireshark dissector into the correct plugin
directory. And in fact we are not. The problem is, the plugin
directory path is constructed at compile time. However, it's
dependent on the wireshark version, e.g.

  /usr/lib/wireshark/plugins/1.12.6

This is rather unfortunate, because if libvirt RPMs were built
with one version, but installed on a system with newer one, the
plugins are not really loaded. This problem lead fedora packagers
to unify plugin path to:

  /usr/lib/wireshark/plugins/

Cool! But this was enabled just in wireshark-1.12.6-4. Therefore,
we must require at least that version.

And while at it, on some distributions, the wireshark.pc file
already has a variable that defines where plugin dir is. Use that
if possible.

Build on non-Linux fails because the virNetDevWaitDadFinish() stub
has unused parameters. Fix by adding appropriate ATTRIBUTE_UNUSED
for these parameters.

Pushing under build-breaker rule.

commit db488c79 assumed that dnsmasq would complete IPv6 DAD before
daemonizing, but in reality it doesn't wait, which creates problems
when libvirt's bridge driver sets the matching "dummy tap device" to
IFF_DOWN prior to DAD completing.

This patch waits for DAD completion by periodically polling the kernel
using netlink to check whether there are any IPv6 addresses assigned
to bridge which have a 'tentative' state (if there are any in this
state, then DAD hasn't yet finished). After DAD is finished, execution
continues. To avoid an endless hang in case something was wrong with
the kernel's DAD, we wait a maximum of 5 seconds.

Such messages do not have NLMSG_ERROR or NLMSG_DONE type
but they are valid responses. We test 'multi-partness'
by looking for NLM_F_MULTI flag.

Commit id '9deb96f9' removed the code to fetch the nodeset from the
CpusetMems cgroup for a running vm in favor of using the return from
virDomainNumatuneFormatNodeset introduced by commit id '43b67f2e'.
However, that API will return the value of the passed 'auto_nodeset'
when placement is VIR_DOMAIN_NUMATUNE_PLACEMENT_AUTO, which happens
to be NULL.

Since commit id 'c74d58ad' started using priv->autoNodeset in order
to manage the auto placement value during qemuProcessStart, it should
be passed along in order to return the correct value if the domain
requests the auto placement.

When a RBD volume has snapshots it can not be removed.

This patch introduces a new flag to force volume removal,
VIR_STORAGE_VOL_DELETE_WITH_SNAPSHOTS.

With this flag any existing snapshots will be removed prior to
removing the volume.

No existing mechanism in libvirt allowed us to pass such information,
so that's why a new flag was introduced.

Use the virProcessGetStartTime implementation also when only the kernel
is FreeBSD, such as on GNU/kFreeBSD.

While parsing device addresses we should use correct base and don't
count on auto-detect.  For example, PCI address uses hex numbers, but
each number starting with 0 will be auto-detected as octal number and
that's wrong.  Another wrong use-case is for PCI address if for example
bus is 10, than it's incorrectly parsed as decimal number.

PCI and CCW addresses have all values as hex numbers, IDE and SCSI
addresses are in decimal numbers.

This calls the PCI-, USB- and SCSI-specific functions just
like qemuHostdev{Prepare,ReAttach}DomainDevices() already do,
and was the missing piece for the qemuHostdev API to nicely
mirror the virHostdev API.

Update qemuProcessReconnect() to use the new function.

Adopt the same names used for virHostdevUpdateActive*Devices() for
consistency's sake and to make it easier to jump between the two.

No functional changes.

A bunch of files that we don't currently parse, and are very

The number of vCPUs for a guest must be between 1 and the

introduces checks to make sure that passing count <= 0

Fix a cut-n-paste error from commit id '35eecdde' where the previous
check for max_sectors seems to have been copied, but the error message
parameter not updated to be ioeventfd

Commit id '1c24cfe9' added error messages for virNumaSetPagePoolSize;
however, virNumaGetHugePageInfo also uses virNumaGetHugePageInfoPath
in order to build the path, but it never checked upon return if
the built path exists which could lead to an error message as follows:

$ virsh freepages 0 1
error: Failed to open file
    '/sys/devices/system/node/node0/hugepages/hugepages-1kB/free_hugepages':
    No such file or directory

Rather than add the same message for the other two callers, adjust
the virNumaGetHugePageInfoPath in order not only build the path, but
also check if the built path exists.  If the path does not exist,
then generate the error message and return failure.

Commit id '1c24cfe9' added new checks and error messaes for failure
scenarios. Let's adjust those error messages to after the call to
virNumaGetHugePageInfoPath in order to provide a more specific error
message depending on node and page_size

After this patch:
 # virsh allocpages --pagesize 2047 --pagecount 1 --cellno 0
 error: operation failed: page size 2047 is not available on node 0

 # virsh allocpages --pagesize 2047 --pagecount 1

Refactor helper virNumaGetHugePageInfoPath to handle returning a directory
path when passed a page_size of 0 and suffix == NULL into a new helper
virNumaGetHugePageInfoDir which will only be called when a directory
path is expected to be returned. This solves the issue where the helper
was called with page_size == 0 expecting a file path in return, but
instead got a directory path and failed in virFileReadAll with:

    error : virFileReadAll:1358 : Failed to read file
                '/sys/devices/system/node/node0/hugepages/': Is a directory

Since virNumaGetPages API expects to return a directory by passing
page_size == 0 and suffix == NULL, it will now call the new helper.
Callers to virNumaGetHugePageInfoPath expect to return a file path
which could then be used in the call to virFileReadAll.

This has been broken for a looong time - in fact, we've been
shipping a mostly-empty NEWS file for at least the past two years.

Including the html namespace and using it for matching elements,
like hacking1.xsl and hacking2.xsl were already doing, makes the
NEWS file useful again.

Add a note explaining that the release list has been split up
by year as well.

Update cfg.mk to ignore the split files during
syntax-check (thanks Martin).

It's better if we stat() file that we are about to chown() at
first and check if there's something we need to change. Not that
it would make much difference, but for the upcoming patches we
need to be doing stat() anyway. Moreover, if we do things this
way, we can drop @chown_errno variable which will become
redundant.
