2014-03-05iscsi: Use bs->sg for everything else than disksKevin Wolf
The current iscsi block driver code makes the rather arbitrary decision that TYPE_MEDIUM_CHANGER and TYPE_TAPE devices have bs->sg = 1 and all other device types are disks. Instead of this, check for TYPE_DISK to expose the disk interface and make everything else bs->sg = 1. In particular, this includes devices with TYPE_STORAGE_ARRAY, which is what LUN 0 of an iscsi target is. (See https://bugzilla.redhat.com/show_bug.cgi?id=1067784 for the exact scenario.)

2014-02-28block: gluster - add reopen support.Jeff Cody
Gluster does parse open flags in its .bdrv_open() implementation, and the .bdrv_reopen_* implementations need to do the same. A new gluster connection to the image file to be created is established in the .bdrv_reopen_prepare(), and the image file opened with the new flags. If this is successful, then the old image file is closed, and the old connection torn down. The relevant structure pointers in the gluster state structure are updated to the new connection. If it is not successful, then the new file handle and connection is abandoned (if it exists), while the old connection is not modified at all. With reopen supported, block-commit (and offline commit) is now also supported for image files whose base image uses the native gluster protocol driver.

2014-02-21quorum: Simplify quorum_open()Max Reitz
Although it may not look like it, this patch simplifies quorum_open(). qdict_array_split() is now able to return QLists with different objects than only QDicts, therefore it will now do all the work and quorum_open() does not have to handle reference strings by itself. This allows mixing full option dicts and reference strings for specifying the child block devices of quorum; furthermore, it improves handling of malformed specifications.

2014-02-21quorum: Add quorum mechanism.Benoît Canet
This patchset enables the core of the quorum mechanism. The num_children reads are compared to get the majority version and if this version exists more than threshold times the guest won't see the error at all. If a block is corrupted or if an error occurs during an IO or if the quorum cannot be established QMP events are used to report to the management. Use gnutls's SHA-256 to compare versions. --enable-quorum must be used to enable the feature.

2014-02-21quorum: Create quorum.c, add QuorumChildRequest and QuorumAIOCB.Benoît Canet
Quorum is a block filter mirroring writes to num_children children. For reads quorum reads each children and does a vote. If more than vote_threshold versions are identical the quorum is reached and this winning version is returned to the guest. So quorum prevents bit corruption. For high availability purpose minority errors are reported via QMP but the guest does not see them. This patch creates the driver C source file and introduces the structures that will be used in asynchronous reads and writes.
