Express a properly terminated backing chain by putting a
virStorageSource of type VIR_STORAGE_TYPE_NONE in the chain. The newly
used helpers simplify this greatly.
The change fixes a bug as formatting an incomplete backing chain and
parsing it back would end up in expressing a terminated chain since
src->backingStoreRaw was not populated. By relying on the terminator
object this can be now processed appropriately.
Add helpers that will simplify checking if a backing file is valid or
whether it has backing store. The helper virStorageSourceIsBacking
returns true if the given virStorageSource is a valid backing store
member. virStorageSourceHasBacking returns true if the virStorageSource
has a backing store child.
Adding these functions creates a central points for further refactors.
Storage driver uses virStorageSource only partially to store it's
configuration but fully when parsing backing files of storage volumes.
This patch sets the 'type' field to a value other than
VIR_STORAGE_TYPE_NONE so that further patches can add a terminator
element to backing chains without breaking iteration.
The backing store indexes were not bound to the storage sources in any
way. To allow us to bind a given alias to a given storage source we need
to save the index in virStorageSource. The backing store ids are now
generated when detecting the backing chain.
Since we don't re-detect the backing chain after snapshots, the
numbering needs to be fixed there.
In preparation for privatizing the object, use the accessor to fetch
the obj->def instead of the direct reference.

We have been trying to implement the ALLOCATE flag to mean
"the volume should be fully allocated after the resize".
Since commit b0579ed9 we do not allocate from the existing
capacity, but from the existing allocation value.
However this value is a total of all the allocated bytes,
not an offset.
For a sparsely allocated file:
$ perl -e 'print "x"x8192;' > vol1
$ fallocate -p -o 0 -l 4096 vol1
$ virsh vol-info vol1 default
Capacity: 8.00 KiB
Allocation: 4.00 KiB
Treating allocation as an offset would result in an incompletely
allocated file:
$ virsh vol-resize vol1 --pool default 16384 --allocate
Capacity: 16.00 KiB
Allocation: 12.00 KiB
Call fallocate from zero on the whole requested capacity to fully
allocate the file. After that, the volume is fully allocated
after the resize:
$ virsh vol-resize vol1 --pool default 16384 --allocate
$ virsh vol-info vol1 default
Capacity: 16.00 KiB
Allocation: 16.00 KiB

If a Disk pool was defined/created using XML that either didn't
specify a specific format or specified format type='unknown', then
restarting a pool after an initial disk backend build with overwrite
would fail after a libvirtd restart for a non-autostarted pool.
This is because the persistent pool data is not updated during pool
build w/ overwrite processing to have the VIR_STORAGE_POOL_DISK_DOS
default format.
So in addition to the alteration done during disk build processing,
alter the default expectation for disk startup to be DOS if nothing
has been defined yet. That will either succeed if the pool had been
successfully built previously using the default DOS format or fail
with a message indicating the format is something else that does not
match the expect format 'dos'.

Rather than using refreshVol which essentially only updates the
allocation, capacity, and permissions for the volume, but not
the format which does get updated in a pool refresh - let's use
the same helper that pool refresh uses in order to update the
volume target.
Our backing probing code handles directory file types properly in
virStorageFileGetMetadataRecurse(), by that I mean it leaves them
alone. However its caller, the virStorageFileGetMetadata() resets the
type to raw before probing, without even checking the type. We need
to special-case TYPE_DIR in order to achieve desired results.
Also, in order to properly test this, we need to stop resetting format
of volumes in tests for TYPE_DIR (probably the reason why we didn't
catch that and why the test data didn't need to be modified).

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.

If a remote call fails during event registration (more than likely from
a network failure or remote libvirtd restart timed just right), then when
calling the virObjectEventStateDeregisterID we don't want to call the
registered @freecb function because that breaks our contract that we
would only call it after succesfully returning. If the @freecb routine
were called, it could result in a double free from properly coded
applications that free their opaque data on failure to register, as seen
in the following details:
Program terminated with signal 6, Aborted.

The double dereference of 'pyobj_cbData' is triggered in the following way:
(1) libvirt_virConnectDomainEventRegisterAny is invoked.
(2) the event is successfully added to the event callback list
(virDomainEventStateRegisterClient in
remoteConnectDomainEventRegisterAny returns 1 which means ok).
(3) when function remoteConnectDomainEventRegisterAny is hit,
network connection disconnected coincidently (or libvirtd is
restarted) in the context of function 'call' then the connection
is lost and the function 'call' failed, the branch
virObjectEventStateDeregisterID is therefore taken.
(4) 'pyobj_conn' is dereferenced the 1st time in
libvirt_virConnectDomainEventFreeFunc.
(5) 'pyobj_cbData' (refered to pyobj_conn) is dereferenced the
2nd time in libvirt_virConnectDomainEventRegisterAny.
(6) the double free error is triggered.
Resolve this by adding a @doFreeCb boolean in order to avoid calling the
freeCb in virObjectEventStateDeregisterID for any remote call failure in
a remoteConnect*EventRegister* API. For remoteConnect*EventDeregister* calls,
the passed value would be true indicating they should run the freecb if it
exists; whereas, it's false for the remote call failure path.

During 'matrix' testing of all possible combinations I found that if
device is formated with "gpt" first, then an attempt is made to format
using "mac", a startup will fail.
Deeper analysis by Peter Krempa indicates that the "mac" table fits
into the first block on the disk. Since the GPT disklabel is stored
at LBA address 1 it is not overwritten at all. Thus it's apparent that
the (blkid) detection tool then prefers GPT over a older disklabel.
The GPT disklabel has also a secondary copy at the last LBA of the disk.
So, follow the same logic as the logical pool in clearing a 1MB swath
at the beginning and end of the device to avoid potential issues with
larger sector sizes for the device.
Also fixed a minor formatting nit in virStorageBackendDeviceIsEmpty call.
Create a wrapper/helper that can be used to call the storage backend
wipe helper - storageBackendVolWipeLocalFile for future use by logical
and disk backends to clear out the partition table rather than having
each open code the same algorithm.
Add bool 'zero_end' and logic that would allow a caller to wipe specific
portions of a target device either from the beginning (the default) or
from the end when zero_end is true.
This will allow for this code to wipe out partition table information
from a device.

Rather than returning true/false and having the caller check if the
vHBA was actually created, let's do that check within the CreateVport
function. That way the caller can faithfully assume success based
on a name start the thread looking for the LUNs. Prior to this change
it's possible that the vHBA wasn't really created (e.g if the call to
virVHBAGetHostByWWN returned NULL), we'd claim success, but in reality
there'd be no vHBA for the pool. This also fixes a second yet seen
issue that if the nodedev was present, but the parent by name wasn't
provided (perhaps parent by wwnn/wwpn or by fabric_name), then a failure
would be returned. For this path it shouldn't be an error - we should
just be happy that something else is managing the device and we don't
have to create/delete it.

Add a new storage driver registration function that will force the
backend code to fail if any of the storage backend modules can't be
loaded. This will make sure that they work and are present.
If driver modules are enabled turn storage driver backends into
dynamically loadable objects. This will allow greater modularity for
binary distributions, where heavyweight dependencies as rbd and gluster
can be avoided by selecting only a subset of drivers if the rest is not
necessary.
The storage modules are installed into 'LIBDIR/libvirt/storage-backend/'
and users can override the location by using
'LIBVIRT_STORAGE_BACKEND_DIR' environment variable.
rpm based distros will at this point install all the backends when
libvirt-daemon-driver-storage package is installed.
Add APIs that allow to dynamically register driver backends so that the
list of available drivers does not need to be known during compile time.
This will allow us to modularize the storage driver on runtime.
Create a virscsihost.c and place the functions there. That removes the
last #ifdef __linux__ from virutil.c.
Take the opporunity to also change the function names and in one case
the parameters slightly
Use the new virNodeDeviceGetParentName instead. Modify the callers to
build the node device scsi_host# name string in order to call the new
function so that proper lookup occurs.
Rather than have them mixed in with the virutil apis, create a separate
virvhba.c module and move the vHBA related calls into there. Soon there
will be more added.
Also modify the names of the functions and some arguments to be more
indicative of what is really happening. Adjust the callers respectively.
While I was changing fchosttest, rather than the non-descriptive names
test1...test6, rename them to match what the test is doing.
Right now, we use simple string comparison both on the source paths

symlinks in its output, e.g. /dev/mappper/lvm_symlink. The same goes for
the pool's source/target, so in order to successfully compare these two
replace plain string comparison with virFileComparePaths which will
resolve all symlinks and canonicalize the paths prior to comparison.
