ccc8c311b2 storage: Internally represent @autostart as bool
Since it's been used that way anyway, let's just convert it to a bool

5bf9b65501 storage: Introduce APIs to search/scan storage pool volumes list
Introduce virStoragePoolObjForEachVolume to scan each volume
calling the passed callback function until all volumes have been
processed in the storage pool volume list, unless the callback
function returns an error.

Introduce virStoragePoolObjSearchVolume to search each volume
calling the passed callback function until it returns true
indicating that the desired volume was found.

40630a8e45 storage: Introduce storage volume add, delete, count APIs
Create/use virStoragePoolObjAddVol in order to add volumes onto list.

Create/use virStoragePoolObjRemoveVol in order to remove volumes from list.

Create/use virStoragePoolObjGetVolumesCount to get count of volumes on list.

For the storage driver, the logic alters when the volumes.obj list grows
to after we've fetched the volobj. This is an optimization of sorts, but
also doesn't "needlessly" grow the volumes.objs list and then just decr
the count if the virGetStorageVol fails.

c09c93cf57 conf: Move <disk> authdef validation
Rather than checking during XML processing, move the checks for correct
and valid auth into virDomainDiskDefParseValidate. This will introduce
virDomainDiskSourceDefParseAuthValidate to validate that the authdef
stored for the virStorageSource is valid. This can then be expanded
to service backingStore sources as well.

Alter the message text slightly as well to distinguish between an
unknown name and an incorrectly used name.  Since type is not a
mandatory field, add the NULLSTR() around the output of the unknown
error. NB, a config using unknown formatting would fail virschematest
since it only accepts 'iscsi' and 'ceph' as "valid" types.

f64f03b5b1 qemu: Provide default LUN=0 for iSCSI if not provided
https://bugzilla.redhat.com/show_bug.cgi?id=1477880

If the "/#" is missing from the provided iSCSI path, then we need
to provide the default LUN of /0; otherwise, QEMU will fail to parse
the URL causing a failure to either create the guest or hotplug
attach the storage.

During post parse, for any iSCSI disk or hostdev, scan the source
path looking for the presence of '/', if found, then we can assume
the LUN is provided.  If not found, alter the input XML to add the
"/0".  This will cause the generated XML to have the generated
value when the domain config is saved after post parse.

c57f3fd2f8 conf: Validate device on update-device
https://bugzilla.redhat.com/show_bug.cgi?id=1439991

Whenever a device is being updated via
virDomainUpdateDeviceFlags() API, we parse the device XML and
ideally run some generic checks to validate the configuration
(e.g. if device defines per-device boot order but the domain has
os/boot element already). Well, that's the theory - due to a
missing check we've jumped early from that check function.

5102be52d8 conf: Properly truncate wide character names in virDomainObjGetShortName
We always truncated the name at 20 bytes instead of characters.  In
case 20 bytes were in the middle of a multi-byte character, then the
string became invalid and various parts of the code would error
out (e.g. XML parsing of that string).  Let's instead properly
truncate it after 20 characters instead.

We cannot test this in our test suite because we would need to know
what locales are installed on the system where the tests are ran and
if there is supported one (most probably there will be, but we cannot
be 100% sure), we could initialize gettext in qemuxml2argvtest, but
there would still be a chance of getting two different (both valid,
though) results.

In order to test this it is enough to start a machine with a name for
which trimming it after 20 bytes would create invalid sequence (e.g.
1234567890123456789č where č is any multi-byte character).  Then start
the domain and restart libvirtd.  The domain would disappear because
such illegal sequence will not go through the XML parser.  And that's
not a bug of the parser, it should not be in the XML in the first
place, but since we don't use any sophisticated formatter, just
mash some strings together, the formatting succeeds.

21bfd1e9b9 conf: error out for multiple source elements while parsing chardev
Currently we accept and correctly parse this chardev XML:

  ...
  <channel type='tcp'>
    <source mode='connect'/>
    <source mode='bind' host='localhost'/>
    <source service='4567'/>
    <target type='virtio' name='test'/>
  </channel>
  ...

The parsed formatted XML is:

  ...
  <channel type='tcp'>
    <source mode='connect' host='localhost' service='4567'/>
    <target type='virtio' name='test'/>
  </channel>
  ...

That behavior is super wrong and should not be allowed.  If you notice
the current parse takes the first found attribute and uses that value,
so for example from the "<source mode='bind' host='localhost'/>" only
the "host" attribute is used.  It works the same way for all possible
attributes that we are able to parse for source element.

This patch enforces providing only one source element for all character
devices, only for UDP type we allow to provide two source elements
since you can specify both modes.

d04bc0278d secret: Fix memory leak in virSecretLoad
If the virSecretLoadValue fails, the code jumped to cleanup without
setting @ret = obj, thus calling virSecretObjListRemove which only
accounts for the object reference related to adding the object to
the list during virSecretObjListAdd, but does not account for the
reference to the object itself as the return of @ret would be NULL
so the caller wouldn't call virSecretObjEndAPI on the object recently
added thus reducing the refcnt to zero.

This patch will perform the ObjListRemove in the failure path of
virSecretLoadValue and Unref @obj in order to perform clean up
and return @obj as NULL. The @def will be freed as part of the
virObjectUnref.

c4030331c8 storage: Fix existing parent check for vHBA creation
https://bugzilla.redhat.com/show_bug.cgi?id=1472277

Commit id '106930aaa' altered the order of checking for an existing
vHBA (e.g something created via nodedev-create functionality outside
of the storage pool logic) which inadvertantly broke the code to
decide whether to alter/force the fchost->managed field to be 'yes'
because the storage pool will be managing the created vHBA in order
to ensure when the storage pool is destroyed that the vHBA is also
destroyed.

This patch moves the check (and checkParent helper) for an existing
vHBA back into the createVport in storage_backend_scsi. It also
adjusts the checkParent logic to more closely follow the intentions
prior to commit id '79ab0935'. The changes made by commit id '08c0ea16f'
are only necessary to run the virStoragePoolFCRefreshThread when
a vHBA was really created because there's a timing lag such that
the refreshPool call made after a startPool from storagePoolCreate*
wouldn't necessarily find LUNs, but the thread would. For an already
existing vHBA, using the thread is unnecessary since the vHBA already
exists and the lag to configure the LUNs wouldn't exist.

4ae9dbea99 nodedev: Convert virNodeDeviceObjListPtr to use hash tables
Rather than use a forward linked list of elements, it'll be much more
efficient to use a hash table to reference the elements by unique name
and to perform hash searches.

This patch does all the heavy lifting of converting the list object to
use a self locking list that contains the hash table. Each of the FindBy
functions that do not involve finding the object by it's key (name) is
converted to use virHashSearch in order to find the specific object.
When searching for the key (name), it's possible to use virHashLookup.
For any of the list perusal functions that are required to evaluate
each object, the virHashForEach function is used.

e5a0579996 qemu: Enable NUMA node tag in pci-root for PPC64
This patch addresses the same aspects on PPC the bug 1103314 addressed
on x86.

PCI expander bus creates multiple primary PCI busses, where each of these
busses can be assigned a specific NUMA affinity, which, on x86 is
advertised through ACPI on a per-bus basis.

For SPAPR, a PHB's NUMA affinities are assigned on a per-PHB basis, and
there is no mechanism for advertising NUMA affinities to a guest on a
per-bus basis. So, even if qemu-ppc manages to get some sort of multi-bus
topology working using PXB, there is no way to expose the affinities
of these busses to the guest. It can only be exposed on a per-PHB/per-domain
basis.

So patch enables NUMA node tag in pci-root controller on PPC.

The way to set the NUMA node is through the numa_node option of
spapr-pci-host-bridge device. However for the implicit PHB, the only way
to set the numa_node is from the -global option. The -global option applies
to all the PHBs unless explicitly specified with the option on the
respective PHB of CLI. The default PHB has the emulated devices only, so
the patch prevents setting the NUMA node for the default PHB.

b8b6abbcd4 conf: Introduce isolation groups
Isolation groups will eventually allow us to make sure certain
devices, eg. PCI hostdevs, are assigned to guest PCI buses in
a way that guarantees improved isolation, error detection and
recovery for machine types and hypervisors that support it,
eg. pSeries guest on QEMU.

This patch merely defines storage for the new information
we're going to need later on and makes sure it is passed from
the hypervisor driver (QEMU / bhyve) down to the generic PCI
address allocation code.

dae23ec345 nodedev: Convert virNodeDeviceObj to use virObjectLockable
Now that we have a bit more control, let's convert our object into
a lockable object and let that magic handle the create and lock/unlock.

This also involves creating a virNodeDeviceEndAPI in order to handle
the object cleanup for API's that use the Add or Find API's in order
to get a locked/reffed object. The EndAPI will unlock and unref the
object returning NULL to indicate to the caller to not use the obj.

In an overall effort to privatize access to virNodeDeviceObj and
virNodeDeviceObjList into the virnodedeviceobj module, move the
object list parsing from node_device_driver and replace with a
call to a virnodedeviceobj helper. This follows other similar
APIs/helpers which peruse the object list looking for some specific
data in order to get/return an @device (virNodeDevice) object to
the caller.

from the driver specific node_device_linux_sysfs into its own API

Nothing in the code deals with sysfs anyway, as that's hidden by the

87e50c9cea nodedev: Alter virNodeDeviceObjRemove
Rather than passing the object to be removed by reference, pass by value
and then let the caller decide whether or not the object should be free'd
and how to handle the logic afterwards. This includes free'ing the object
and/or setting the local variable to NULL to prevent subsequent unexpected
usage (via something like virNodeDeviceObjRemove in testNodeDeviceDestroy).

For now this function will just handle the remove of the object from the
list for which it was placed during virNodeDeviceObjAssignDef.

This essentially reverts logic from commit id '61148074' that free'd the
device entry on list, set *dev = NULL and returned. Thus fixing a bug in
node_device_hal.c/dev_refresh() which would never call dev_create(udi)
since @dev would have been set to NULL.
