* [SCSI] qla4xxx: do not reuse session when connecting to different target portMike Christie2009-01-251-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | qla4xxx does not check the I_T nexus values correctly so it ends up creating one session to the target. If a portal should disappear or they should be reported in different order the driver will think it is already logged in when it could now be speaking to a different target portal or accessing it through a different initiator port (iscsi initiator port is not tied to hardware and is just the initiator name plus isid so you could end up with multiple ports through one host). This patch has the driver check the iscsi scsi port values when matching sessions (we do not check the initiator name because that is static). It results in a portal from each target portal group getting logged into instead of just one per target. In the future the firmware should hopefully send us notification of other sessions that are created to other portals within the same tpgt and the sessions should have different isids.

* [SCSI] qla4xxx: fix host reset dpc raceMike Christie2008-03-051-1/+1
| | | | | | | | | | | | | | | | The host reset callout could be starting to reset the hba at the same time the dpc thread is. This creates lots of problems because they both want to do wierd things with the firmware and interrupts, etc. This patch just has the host reset function fully shutdown the dpc thread before resetting the hba. This patch also moves the setting of the session online bit to fix a potential race with the dpc thread and iscsi recovery thread.

* [SCSI] qla4xxx: directly call iscsi recovery functionsMike Christie2008-02-071-0/+1
| | | | | | | | | | | | | | | | Qla4xxx can just call the iscsi recovery functions directly. There is no need for userspace to do this for qla4xxx, because we do not use the mutex to iterate over devices anymore and iscsi_block /unblock_session can be called from interrupt context or the dpc thread. And having userspace do this just creates uneeded headaches for qla4xxx root situations where the session may experience problems. For example during the kernel shutdown the scsi layer wants to send sync caches, but at this time userspace is not up (iscsid is not running), so we cannot recover from the problem.

| | | | | | | | | | | | | We were using the device delete sysfs file to remove each device then logout. Now in 2.6.21 this will not work because the sysfs delete file returns immediately and does not wait for the device removal to complete. This causes a hang if a cache sync is needed during shutdown. Before .21, that approach had other problems, so this patch fixes the shutdown code so that we remove the target and unbind the session before logging out and shut down the session Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

This is because qla4xxx HBA supports one ethernet and iscsi interfaces per port. Both iscsi and ethernet interfaces share the same state machine.
