* [SCSI] zfcp: Remove sysfs attribute port_addMartin Peschke2008-07-121-46/+0
| | | | | | | | | With the automatic scanning of remote ports in place, there is no need to add remote ports manually. So, remove the port_add attribute.

* [SCSI] zfcp: Automatically attach remote portsSwen Schillig2008-07-128-31/+336
| | | | | | | | | | | Automatically attach the remote ports in zfcp when the adapter is set online. This is done by querying all available ports from the FC namesever. The scan for remote ports is also triggered by RSCNs and can be triggered manually with the sysfs attribute 'port_rescan'.

* [SCSI] zfcp: Add port_state attribute to sysfsSven Schuetz2008-07-121-0/+19
| | | | | | | | | | | | | | | | 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.

* [SCSI] aacraid: prevent copy_from_user() BUG!Mark Salyzyn2008-07-121-0/+33
| | | | | | | | | | | | | | | | | | | | | 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.

* [SCSI] libiscsi, iser, tcp: remove recv_lockMike Christie2008-07-126-117/+144
| | | | | | | | | | | | | | | | | | | 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.

* [SCSI] iscsi class: Add session initiatorname and ifacename sysfs attrs.Mike Christie2008-07-126-39/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

It also allows us to pass iser the leading conn's ep, so we know the ib_deivce being used and can set it as the scsi_host's parent. And that allows scsi-ml to set the dma_mask based on those values.

This patch modifies iser so that userspace can just call the ep_disconnect callback, which will halt all recv IO, before calling the stop_conn callback so we do not have to worry about the conn->recv_lock and suspend rx field. iser just needs to stop the send side from accessing the ib conn.
