| | | | | | | | | | | | | | | In order to let event defines use existing types later, instead of redefine new ones, some old type defines for spice and vnc are changed, and BlockErrorAction is moved from block.h to qapi schema. Note that BlockErrorAction is not merged with BlockdevOnError. At this point, VncInfo is not made a child of VncBasicInfo, because VncBasicInfo has mandatory fields where VncInfo makes them optional.

* block/iscsi: bump libiscsi requirement to 1.9.0Peter Lieven2014-06-181-67/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch lifts the minimum supported libiscsi version from 1.4.0 to 1.9.0 since the BUSY patch required that change. On one this allows us to remove all #ifdefs from the code which makes the code easier to maintain and read. On the other hand I would not recommend libiscsi prior to 1.8.0 for production use because the following important libiscsi fixes for deadlocks and protocol errors are missing prior to 1.8.0: dbe9a1e SOCKET queue cmd PDUs directly in waitpdu queue 30df192 DATA-OUT set pdu->cmdsn appropriately 548bd22 ISCSI fix broken send logic in iscsi_scsi_async_command 14bee10 RECONNECT do not increase CmdSN for immediate PDUs 1f4a66a PDU queue out PDUs in order of itt. 562dd46 PDU avoid incrementing itt to 0xffffffff cd09c0f PDU use serial32 arithmetic for cmdsn, maxcmdsn and expcmdsn. 89e918e SOCKET validate data_size in in_pdu header 91267f5 Limit immediate and unsolicited data to FirstBurstLength Note that libiscsi 1.9.0 was released on Feb 24th, 2013, about one month after 1.8.0.

* block/iscsi: use 16 byte CDBs only when necessaryPeter Lieven2014-06-181-18/+40
| | | | | | | | | | | | | | | | | this patch changes the driver to uses 16 Byte CDBs for READ/WRITE only if the target requires 64bit lba addressing. On one hand this saves 6 bytes in each PDU on the other hand it seems that 10 Byte CDBs seems to be much better supported and tested as a recent issue I had with a major storage supplier lined out. For WRITESAME the logic is a bit more tricky as WRITESAME10 with UNMAP was added really late. Thus a fallback to WRITESAME16 is possible if it supports UNMAP and WRITESAME10 not.

* block/iscsi: handle BUSY conditionPeter Lieven2014-06-181-12/+43
| | | | | | | | | | | | | | | | | | | | this patch adds handling of BUSY status reponse from an iSCSI target. Currently, we fail with -EIO in case of SCSI_STATUS_BUSY while the obvious reaction would be to retry the operation after some time. The retry time is randomly choosen from a range with exponential growth increasing with each retry. This patch includes most of the changes by a an upcoming patch from Stefan Hajnoczi: iscsi: implement .bdrv_detach/attach_aio_context() because I also need the reference to the aio_context for the retry timer to work.
