The volume manager should call driver.create_export()
and driver.remove_export() with an elevated context.
This is already done for remove_export() in some cases
but not in initialize_connection error paths, or for
terminate_connection.
This will at a minimum cause issues with the LVM LIO
driver as its create/remove_export methods uses database
queries requiring admin access (volume_get_iscsi_target_num,
iscsi_target_count_by_host).

Check for silent failure of tgtadm remove
In order to work around a failure to remove targets that
had a reconnect the force flag was added to the tgt delete cmd.
(https://bugs.launchpad.net/cinder/+bug/1159948)
It turns out there's a bug in tgt where some versions will
sometimes silently fail when using the force flag.
(https://bugs.launchpad.net/ubuntu/+source/tgt/+bug/1305343)
The problem is that in the gates since we merged the force change
there's a very high number of cases where lvremove fails because
the device is still active. It appears that this is a result of
the silent force failures in target.
This patch adds a simple check after the force target removal,
if it detects the target is still present it reverts back to the old
non-force method to catch the cases that don't actually need the
force option.
This is a work-around until the version of target in the distros
is updated and can be used reliably, but closes the gate issue
bug that was reported.

_translate_from_glance() can cause an unnecessary HTTP request
After returning from a get() call to python-glanceclient, cinder runs a
translation function on the returned Image to get the data it wants. Part of
this process is checking for an expected set of attributes, one of which is
the deletion time ('deleted_at'). However, if the image has not been deleted,
deleted_at key will not exist. This forces another call to glance to occur for
the same image. A similar problem exists for the checksum attribute, which does
not exist before an image is active. The fix here is to only consider
deleted_at and checksum if they are expected to be present.

Fixes a problem in attach volume in EMC driver.
This patch fixes a problem in attach volume in EMC SMI-S driver.
The existing logic checks if a volume is already attached to any host,
but it doesn't check whether a volume is already attached to the specific

could return success (thinking it is already attached), but nova will
fail to discover the LUN later and fail the attach.
This patch adds a check to see if a volume is already attached to a
specific host. If not, it will do the attach. The reason that the
volume being attached already could be due to a nova live-migration
use case. Cinder doesn't support multiple attaches currently, but
allows a volume to be attached multiple times from nova during

combination of filters and limit will only work if all volumes matching
the filters are in the page of data being retrieved from the database.

retrieved from the database starting at index 100 and that you query for
all volumes with a name of "foo" while specifying a limit of 50. In this
