[SCSI] iscsi class: regression - fix races with state manipulation and blocking/unblocking

2008-03-05T18:04:09Z

For qla4xxx, we could be starting a session, but some error (network, target, IO from a device that got started, etc) could cause the session to fail and curring the block/unblock and state manipulation could race with each other. This patch just has those operations done in the single threaded iscsi eh work queue, so that way they are serialized. Signed-off-by: Mike Christie Signed-off-by: James Bottomley

[SCSI] libsas: export sas_find_local_phy function

2008-02-24T05:52:30Z

This is needed by the to be added I_T reset function in aic94xx. It needs to know the local phy so it can send a link or hard reset along the path. Signed-off-by: James Bottomley

[SCSI] update SG_ALL to avoid causing chaining

2008-02-11T19:40:13Z

Since the sg chaining patches went in, our current value of 255 for SG_ALL excites chaining on some drivers which cannot support it (and would thus oops). Redefine SG_ALL to mean no sg table size preference, but use the single allocation (non chained) limit. This also helps for drivers that use it to size an internal table. We'll do an opt in system later where truly chaining supporting drivers can define their sg_tablesize to be anything up to SCSI_MAX_SG_CHAIN_ELEMENTS. Signed-off-by: James Bottomley

[SCSI] Small cleanups for scsi_host.h

2008-02-08T00:02:43Z

Small cleanups in scsi_host.h. Few #defines make me wonder if their description is still up to date..? Signed-off-by: Pavel Machek Signed-off-by: Andrew Morton Signed-off-by: James Bottomley

[SCSI] add protocol definitions

2008-02-08T00:02:41Z

A lot of SCSI command replies have a protocol ID field. Add definitions for the interpretation of that from SPC-3. Signed-off-by: James Bottomley

[SCSI] libiscsi: fix session age rollover and remove cid encoding

2008-02-08T00:02:37Z

The session age mask is only 4 bits, but session->age is 32. When it gets larger then 15 and we try to or the bits some bits get dropped and the check for session age in iscsi_verify_itt is useless. The ISCSI_CID_MASK related bits are also useless since cid is always one. Signed-off-by: Mike Christie Signed-off-by: James Bottomley

[SCSI] iscsi: fix up iscsi printk prefix

2008-02-08T00:02:37Z

Some iscsi class messages have the dev_printk prefix and some libiscsi and iscsi_tcp messages have "iscsi" or the module name as a prefix which is normally pretty useless when trying to figure out which session or connection the message is attached to. This patch adds iscsi lib and class dev_printks so all messages have a common prefix that can be used to figure out which object printed it.

[SCSI] iscsi class: add async scan helper

2008-02-08T00:02:35Z

In qla4xxx's probe it will call the iscsi session setup functions for session that got setup on the initial start. This then makes it easy for the iscsi class to export a helper which indicates when those scans are done. Signed-off-by: Mike Christie Signed-off-by: James Bottomley

[SCSI] iscsi class: add session scanning

2008-02-08T00:02:35Z

This just adds iscsi session scanning which works like fc rport scanning. The future patches will hook the drivers into Mathew Wilcox's async scanning infrastructure, so userspace does not have to special case iscsi and so userspace does not have to make a extra special case for hardware iscsi root scanning.

[SCSI] iscsi class, libiscsi: add iscsi sysfs session state file

2008-02-08T00:02:34Z

This adds a iscsi session state file which exports the session state for both software and hardware iscsi. It also hooks libiscsi in. Signed-off-by: Mike Christie Signed-off-by: James Bottomley
