[SCSI] fix incorrect value of SCSI_MAX_SG_CHAIN_SEGMENTS due to include file ordering

2011-01-24T17:49:34Z

If the compiled object doesn't include linux/scatterlist.h before scsi/scsi.h, it will get an incorrect definition of SCSI_MAX_SG_CHAIN_SEGMENTS. Signed-off-by: David Dillow Cc: stable@kernel.org Signed-off-by: James Bottomley

[SCSI] libiscsi: do not take host lock in queuecommand

2010-12-31T15:52:44Z

iscsi_tcp, ib_iser, cxgb*, be2iscsi and bnx2i do not use the host lock and do not take the session lock against a irq, so this patch drops the DEF_SCSI_QCMD use. Instead we just take the session lock and disable bhs. Signed-off-by: Mike Christie Signed-off-by: James Bottomley

[SCSI] libiscsi: add more informative failure message during iscsi scsi eh

2010-12-31T15:51:54Z

This adds a more informative error code and message for the iscsi scsi eh session drop paths. This allows you to distinguish if the session was dropped due to a connection failure vs the iscsi layer dropping the session due to scsi eh failure processing.

[SCSI] Add missing SPC-4 CDB and MAINTENANCE_[IN,OUT] service action definitions

2010-12-21T18:37:30Z

This patch adds a handful of missing CDBs defs that are used by TCM persistent reservation logic in the SPC-4 defined CDB exclusion table for registrations and reservations. This includes a number of missing MI_* and MO_* prefixed service actions defs for MAINTENANCE_IN and MAINTENANCE_OUT that are mentioned wrt to persistent registration and reservation status for the SCSI Initiator Port.

[SCSI] libfc: fix statistics for FCP input/output megabytes

2010-12-21T18:24:34Z

The statistics for InputMegabytes and OutputMegabytes are misnamed. They're accumulating bytes, not megabytes. The statistic returned via /sys must be in megabytes, however, which is what the HBA-API wants. The FCP code needs to accumulate it in bytes and then divide by 1,000,000 (not 2^20) before it presented via sysfs. This affects fcoe.ko only, not fnic. The fnic driver correctly by accumulating bytes and then converts to megabytes. I checked that libhbalinux is using the /sys file directly without conversion. BTW, qla2xxx does divide by 2^20, which I'm not fixing here. Signed-off-by: Joe Eykholt Signed-off-by: Robert Love Signed-off-by: James Bottomley

[SCSI] libfcoe: retry rejected FLOGI to another FCF if possible

2010-12-21T18:24:32Z

Switches using multiple-FCFs may reject FLOGI in order to balance the load between multiple FCFs. Even though the FCF was available, it may have more load at the point we actually send the FLOGI. If the FLOGI fails, select a different FCF if possible, among those with the same priority. If no other FCF is available, just deliver the reject to libfc for retry.

[SCSI] libfc: remove tgt_flags from fc_fcp_pkt struct

2010-12-21T18:24:22Z

We can easily remove the tgt_flags from fc_fcp_pkt struct and use rpriv->tgt_flags directly where needed. Signed-off-by: John Fastabend Signed-off-by: Robert Love Signed-off-by: James Bottomley
