This patch fixes two bugs that are related. 1. Old tools did not set can_queue/cmds_max. This patch modifies libiscsi so that when we add the host we catch this and set it to the default. 2. iscsi_tcp thought that the scsi command that was passed to the eh functions needed a iscsi_cmd_task allocated for it. It only needed a mgmt task, and now it does not matter since it all comes from the same pool and libiscsi handles this for the drivers. ib_iser had copied iscsi_tcp's code and set can_queue to its max - 1 to handle this. So this patch removes the max -1, and just sets it to the max. Signed-off-by: NMike Christie <michaelc@cs.wisc.edu> Signed-off-by: NJames Bottomley <James.Bottomley@HansenPartnership.com>

The sysfs attribute /sys/class/fc_host/hostX/port_state was not set by zfcp so far. Now, the appropriate members of the fc_function_template struct are set during its initialziation. The first is a boolean to show the port state. The second is a function pointer to the function zfcp_get_host_port_state, which reads the port state from our adapter status bits and calls fc_host_port_state with the approriate port state afterwards.

Seen: kernel BUG at arch/i386/lib/usercopy.c:872 under a 2.6.18-8.el5 kernel. Traced it to a garbage-in/garbage-out ioctl condition in the aacraid driver. Adaptec's special ioctl scb passthrough needs to check the validity of the individual scatter gather count fields to the maximum the adapter supports. Doing so will have the side effect of preventing copy_from_user() from bugging out while populating the dma buffers. This is a hardening effort, issue was triggered by an errant version of the management tools and thus the BUG should not be seen in the field.

The recv lock was defined so the iscsi layer could block the recv path from processing IO during recovery. It turns out iser just set a lock to that pointer which was pointless. We now disconnect the transport connection before doing recovery so we do not need the recv lock. For iscsi_tcp we still stop the recv path incase older tools are being used. This patch also has iscsi_itt_to_ctask user grab the session lock and has the caller access the task with the lock or get a ref to it in case the target is broken and sends a tmf success response then sends data or a response for the command that was supposed to be affected bty the tmf.

This adds two new attrs used for creating initiator ports and binding sessions to hardware. The session level initiatorname: Since bnx2i does a scsi_host per host device, we need to add the iface initiator port settings on the session, so we can create multiple initiator ports (each with different inames) per device/scsi_host. The current iname reflects that qla4xxx can have one iname per hba, and we are allocating a host per session for software. The iname on the host will remain so we can export and set the hba level qla4xxx setting. The ifacename attr: To bind a session to a some peice of hardware in userspace we maintain some mappings, but during boot or iscsid restart (iscsid contains the user space part of the driver) we need to be able to figure out which of those host mappings abstractions maps to certain sessions. This patch adds a ifacename attr, which userspace can set to id the host side of the endpoint across pivot_roots and iscsid restarts.
