SCSI: osd_protocol.h: Add missing #include

2009-12-14T17:44:45Z

commit 0899638688f223fd9e9fee60d662665e11693d12 upstream. include/scsi/osd_protocol.h uses ALIGN() without an #include , leading to: | include/scsi/osd_protocol.h:362: error: implicit declaration of function 'ALIGN' Signed-off-by: Martin Michlmayr Signed-off-by: Boaz Harrosh Signed-off-by: James Bottomley Signed-off-by: Greg Kroah-Hartman

SCSI: scsi_lib_dma: fix bug with dma maps on nested scsi objects

2009-12-14T17:44:44Z

commit d139b9bd0e52dda14fd13412e7096e68b56d0076 upstream. Some of our virtual SCSI hosts don't have a proper bus parent at the top, which can be a problem for doing DMA on them This patch makes the host device cache a pointer to the physical bus device and provides an extra API for setting it (the normal API picks it up from the parent). This patch also modifies the qla2xxx and lpfc vport logic to use the new DMA host setting API. Acked-By: James Smart Signed-off-by: James Bottomley Signed-off-by: Greg Kroah-Hartman

[SCSI] fix async scan add/remove race resulting in an oops

2009-11-26T15:43:39Z

Async scanning introduced a very wide window where the SCSI device is up and running but has not yet been added to sysfs. We delay the adding until all scans have completed to retain the same ordering as sync scanning. This delay in visibility causes an oops if a device is removed before we make it visible because the SCSI removal routines have an inbuilt assumption that if a device is in SDEV_RUNNING state, it must be visible (which is not necessarily true in the async scanning case). Fix this by introducing an additional is_visible flag which we can use to condition the tear down so we do the right thing for running but not yet made visible.

[SCSI] Fix incorrect reporting of host protection capabilities

2009-11-06T17:50:52Z

The advent of DIF Type 2 devices exposed some missing break statements in the protection mask switch constructs. However, rewriting the code to use an index into a small static array seemed like a more elegant solution. Signed-off-by: Martin K. Petersen Signed-off-by: James Bottomley

[SCSI] libiscsi: iscsi_session_setup to allow for private space

[SCSI] sd: Support disks formatted with DIF Type 2

2009-10-02T14:47:04Z

Disks formatted with DIF Type 2 reject READ/WRITE 6/10/12/16 commands when protection is enabled. Only the 32-byte variants are supported. Implement support for issusing 32-byte READ/WRITE and enable Type 2 drives in the protection type detection logic. Signed-off-by: Martin K. Petersen Signed-off-by: James Bottomley

[SCSI] sd: Detach DIF from block integrity infrastructure

2009-10-02T14:46:39Z

So far we have only issued DIF commands if CONFIG_BLK_DEV_INTEGRITY is enabled. However, communication between initiator and target should be independent of protection information DMA. There are DIF-only host adapters coming out that will be able to take advantage of this. Move the relevant DIF bits to sd.c. Signed-off-by: Martin K. Petersen Signed-off-by: James Bottomley

[SCSI] Deprecate SCSI_PROT_*_CONVERT operations

2009-10-02T14:46:25Z

The checksum format is orthogonal to whether the protection information is being passed on beyond the HBA or not. It is perfectly valid to use a non-T10 CRC with WRITE_STRIP and READ_INSERT. Consequently it no longer makes sense to explicitly refer to the conversion in the protection operation. Update sd_dif and lpfc accordingly. Signed-off-by: Martin K.

[SCSI] libiscsi, bnx2i: make bound ep check common

2009-09-12T14:35:33Z

bnx2i currently has a check for if a ep is properly bound, so if iscsi_queuecommand/xmit_task is called while there is no ep we will not queue IO. be2iscsi sends IO from queuecommand/xmit_task like how bnx2i does and needs a similar test. This patch has us just use the suspend_bit test for this. When ep_poll has succeeed iscsid will call conn_bind, the LLD will then call iscsi_conn_bind which will clear the suspend bit. When ep_disconnect is called (or if there is a conn error) we set the suspend bit. For the ep_disconnect case I am adding a helper in this patch that will take the session lock to make sure iscsi_queuecommand/xmit_task is not running and it will set the suspend bit.
