https://bugzilla.redhat.com/show_bug.cgi?id=1174096

When both parameter have lockspaces present, virDomainLeaseIndex
always returns -1 even there is a lease the same with the one we
check. This is due to broken logic in 'if-else' statement.

311b4a677f qemu: Allow system pages to <memoryBacking/>
https://bugzilla.redhat.com/show_bug.cgi?id=1173507

It occurred to me that OpenStack uses the following XML when not using
regular huge pages:

  <memoryBacking>
    <hugepages>
      <page size='4' unit='KiB'/>
    </hugepages>
  </memoryBacking>

However, since we are expecting to see huge pages only, we fail to
startup the domain with following error:

  libvirtError: internal error: Unable to find any usable hugetlbfs
  mount for 4 KiB

While regular system pages are not huge pages technically, our code is
prepared for that and if it helps OpenStack (or other management
applications) we should cope with that.

5fc1c51743 conf: Fix libvirtd crash matching hostdev XML
https://bugzilla.redhat.com/show_bug.cgi?id=1174053

Introduced by commit id '17bddc46f' - fix a libvirtd crash when
matching a network iscsi hostdev with a host iscsi hostdev.

When we use attach-device to coldplug a network iscsi hostdev,
libvirt will check if there is already a device in XML. But if
the 'b' is a host iscsi hostdev and 'a' is a network iscsi hostdev,
then libvirtd will crash in virDomainHostdevMatchSubsysSCSIiSCSI
because 'b' doesn't have a hostname.

Add a check in virDomainHostdevMatchSubsys, if the a's protocol
and b's protocol is not the same.

Following is the backtrace:

ca4f9518b8 virconf: Introduce VIR_CONF_ULONG
https://bugzilla.redhat.com/show_bug.cgi?id=1160995

In our config files users are expected to pass several integer values
for different configuration knobs. However, majority of them expect a
nonnegative number and only a few of them accept a negative number too
(notably keepalive_interval in libvirtd.conf).
Therefore, a new type to config value is introduced: VIR_CONF_ULONG
that is set whenever an integer is positive or zero. With this
approach knobs accepting VIR_CONF_LONG should accept VIR_CONF_ULONG
too.

c5a54917d5 qemu: add a qemuInterfaceStopDevices(), called when guest CPUs stop
We now have a qemuInterfaceStartDevices() which does the final
activation needed for the host-side tap/macvtap devices that are used
for qemu network connections. It will soon make sense to have the
converse qemuInterfaceStopDevices() which will undo whatever was done
during qemuInterfaceStartDevices().

A function to "stop" a single device has also been added, and is
called from the appropriate place in qemuDomainDetachNetDevice(),
although this is currently unnecessary - the device is going to
immediately be deleted anyway, so any extra "deactivation" will be for
naught. The call is included for completeness, though, in anticipation
that in the future there may be some required action that *isn't*
nullified by deleting the device.

This patch is a part of a more complete fix for:

879c13d6cc qemu: always call qemuInterfaceStartDevices() when starting CPUs
The patch that added qemuInterfaceStartDevices() (upstream commit
82977058f5) had an extra conditional to
prevent calling it if the reason for starting the CPUs was
VIR_DOMAIN_RUNNING_UNPAUSED or VIR_DOMAIN_RUNNING_SAVE_CANCELED.  This
was put in by the author as the result of a reviewer asking if it was
necessary to ifup the interfaces in *all* occasions (because these
were the two cases where the CPU would have already been started (and
stopped) once, so the interface would already be ifup'ed).

It turns out that, as long as there is no corresponding
qemuInterfaceStopDevices() to ifdown the interfaces anytime the CPUs
are stopped, neglecting to ifup when reason is RUNNING_UNPAUSED or
RUNNING_SAVE_CANCELED doesn't cause any problems (because it just
happens that the interface will have already been ifup'ed by a prior
call when the CPU was previously started for some other reason).

However, it also doesn't *help*, and there will soon be a
qemuInterfaceStopDevices() function which *will* ifdown these
interfaces when the guest CPUs are stopped, and once that is done, the
interfaces will be left down in some cases when they should be up (for
example, if a domain is paused and then unpaused).

So, this patch is removing the condition in favor of always calling
qemuInterfaeStartDevices() when the guest CPUs are started.

This patch (and the aforementioned patch) resolve:

c7d1c139ca qemu: avoid rare race when undefining domain
When one domain is being undefined and at the same time started, for
example, there is a possibility of a rare problem occuring.

 - Thread 1 does virDomainUndefine(), has the lock, checks that the
   domain is active and because it's not, calls
   virDomainObjListRemove().

 - Thread 2 does virDomainCreate() and tries to lock the domain.

 - Thread 1 needs to lock domain list in order to remove the domain from
   it, but must unlock domain first (proper order is to lock domain list
   first and the domain itself second).

 - Thread 2 grabs the lock, starts the domain and releases the lock.

 - Thread 1 grabs the lock and removes the domain from list.

With this patch:

 - The undefining domain gets marked as "to undefine" before it is
    unlocked.

 - If domain is found in any of the search APIs, it's returned only if
   it is not marked as "to undefine".  The check is done while the
   domain is locked.

dd324bb270 Do not format CPU features without a model
For host-passthrough CPU we don't honor the CPU
features specified in the XML, but we allow
outputting them via the UPDATE_CPU flag for dumpxml,
this gives user a rough idea of what features the CPU
might have.

After restoring a managedsave'd domain, the features
might end up in the live status XML (in /var/run) without
the model. This XML cannot be parsed by the daemon after
restart and the domain might disappear.

This fix skips formatting the features for HOST_PASSTHROUGH
when UPDATE_CPU is not specified, so the newly restored domains
and newly created snapshots won't be affected.

Note: this doesn't fix existing snapshots or already restored
running domains.

729251692f viriscsi: Need to sendtargets on Initiator IQN
https://bugzilla.redhat.com/show_bug.cgi?id=1172015

The refactoring done as part of commit id '59446096' caused a regression
for the multi initiator IQN commit '6aabcb5b' because the sendtargets was
not done on/for the initiator IQN prior to login (or trying to disable
autologin)

Prior to that commit, the paths were essentially

virStorageBackendISCSIStartPool
    virStorageBackendISCSILogin
        virStorageBackendISCSIConnection
            if initiatoriqn
                virStorageBackendCreateIfaceIQN
                Issue sendtargets
                Perform --login
            else
                Issue sendtargets
                Perform --login

After that commit:

virStorageBackendISCSIStartPool
    Issue sendtargets
    Call virStorageBackendISCSIConnection
        If initiatoriqn
            virStorageBackendCreateIfaceIQN
            Perform --login
        else
            Perform --login

So for non initiator IQN paths, nothing changed. For the initiator path,
the --login fails as does any attempts to change autologin via "--op update
--name node.startup --value manual".

57023c0a3a CVE-2014-8131: Fix possible deadlock and segfault in qemuConnectGetAllDomainStats()
When user doesn't have read access on one of the domains he requested,
the for loop could exit abruptly or continue and override pointer which
pointed to locked object.

This patch fixed two issues at once.  One is that domflags might have
had QEMU_DOMAIN_STATS_HAVE_JOB even when there was no job started (this
is fixed by doing domflags |= QEMU_DOMAIN_STATS_HAVE_JOB only when the
job was acquired and cleaning domflags on every start of the loop.
Second one is that the domain is kept locked when
virConnectGetAllDomainStatsCheckACL() fails and continues the loop when
it didn't end.  Adding a simple virObjectUnlock() and clearing the
pointer ought to do.

f36d9285cd security: Manage SELinux labels on shared/readonly hostdev's
https://bugzilla.redhat.com/show_bug.cgi?id=1082521

Support for shared hostdev's was added in a number of commits, initially
starting with 'f2c1d9a80' and most recently commit id 'fd243fc4' to fix
issues with the initial implementation.  Missed in all those changes was
the need to mimic the virSELinux{Set|Restore}SecurityDiskLabel code to
handle the "shared" (or shareable) and readonly options when Setting
or Restoring the SELinux labels.

This patch will adjust the virSecuritySELinuxSetSecuritySCSILabel to not
use the virSecuritySELinuxSetSecurityHostdevLabelHelper in order to set
the label. Rather follow what the Disk code does by setting the label
differently based on whether shareable/readonly is set.  This patch will
also modify the virSecuritySELinuxRestoreSecuritySCSILabel to follow
the same logic as virSecuritySELinuxRestoreSecurityImageLabelInt and not
restore the label if shared/readonly
