When zfcp receives 16 unsolicited status messages, this could trigger an adapter reopen. In this case, first try to send a new status read, and only if this fails, go through the recovery. Signed-off-by:

In some situations the auto port attachment task is started before the ERP is finished. To prevent this unwanted situation we wait until the adapter is up and running before we start our work. Signed-off-by:

This patch adds a new device driver to support the Virtual Fibre Channel interface on IBM Power based servers. The Virtual I/O Server on IBM Power servers utilizes N-Port ID Virtualization to export a Virtual Fibre Channel adapter to the client. This driver is the client device driver. Signed-off-by:

The features enable bit has to be set in the config2 register before we can be absolutely sure we will probe a correct part unique ID and family code from the transfer-count-high register. Also, reload the CFACT, STP, SOFF, and TIMEO near the end of esp_reset_esp(). From a patch by Maciej W. Rozycki. Signed-off-by:

class_find_device gets a ref to the device so we must release it. The class will serialize access to the ep so we do not have to worry about a remove racing with the callers access, so we can simplify the use and drop the ref right away. Signed-off-by:

Update iscsi class version number. Signed-off-by:

Mike Christie authored
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:

Miscellaneous Fixes: - Fix bug in mbox sysfs interface that locked in EAGAIN if discovery stalled. - Fix missing error message when npiv and loop are true when link up occurs. - Fix panic in lpfc_scsi_cmd_iocb_cmpl: scsi_buf was NULL, but created race conditions with other code paths. - Fix error in sysfs mailbox structure that didn't rezero on next use. - Add missing mempool_free() to attachment failure path - Fix missing put of ndlp structure during driver unload. - Fix applications unable to send mailbox commands during discovery. - Remove unused argument (type) from function lpfc_post_buffer() API - Fix vport name is not shown after hbacmd vportcreate. - Remove repeated code statements.

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'. Signed-off-by:

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. [jejb: fixed up compile failure] Signed-off-by:

We don't need to hold bsg_mutex during bsg_complete_all_commands(). It leads to a problem that we block bsg_unregister_queue during bsg_complete_all_commands (untill all the outstanding commands complete).

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. Signed-off-by:

This hooks iser into the iscsi endpoint code. Previously it handled the lookup and allocation. This has been made generic so bnx2i and iser can share it. 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.
