HighPoint RocketRAID 3220/3320 series 8 channel PCI-X SATA RAID Host Adapters. Fixes from original submission: Merge Andrew Morton's patches: - Provide locking for global list - Fix debug printks - uninline function with multiple callsites - coding style fixups - remove unneeded casts of void* - kfree(NULL) is legal - Don't "succeed" if register_chrdev() failed - otherwise we'll later unregister a not-registered chrdev. - Don't return from hptiop_do_ioctl() with the spinlock held. - uninline __hpt_do_ioctl() Update for Arjan van de Ven's comments: - put all asm/ includes after the linux/ ones - replace mdelay with msleep - add pci posting flush - do not set pci command reqister in map_pci_bar - do not try merging sg elements in hptiop_buildsgl() - remove unused outstandingcommands member from hba structure - remove unimplemented hptiop_abort() handler - remove typedef u32 hpt_id_t Other updates: - fix endianess Signed-off-by:

Initial pass at converting the gdth driver away from the scsi_request interface so that the request interface can be removed post 2.6.18 without breaking gdth. Based on changes from Christoph Hellwig <hch@lst.de> Signed-off-by:

Various scsi drivers use scsi_cmnd.buffer and scsi_cmnd.bufflen in their queuecommand functions. Those fields are internal storage for the midlayer only and are used to restore the original payload after request_buffer and request_bufflen have been overwritten for EH. Using the buffer and bufflen fields means they do very broken things in error handling. Signed-off-by:

We can race and misset the suspend bit if iscsi_write_space is called then iscsi_send returns with a failure indicating there is no space. To handle this this patch returns a error upwards allowing xmitworker to decide if we need to try and transmit again. For the no write space case xmitworker will not retry, and instead let iscsi_write_space queue it back up if needed (this relies on the work queue code to properly requeue us if needed).

If recovery failed or we are in recovery only overwrite the state if we are going to terminate the session or if we logged back in. STOP_CONN_SUSPEND and conn_cnt are not used. We only support a single connection session ATM, so cleanup that code while we are working around it. Signed-off-by:

(LSI Logic / Symbios Logic SAS1064E PCI-Express Fusion-MPT SAS (rev 01)) o Problem is easily reproducible, if system crashed while some disk activity like cp operation was going on. o After a system crash, devices are not shutdown and capture kernel starts booting while skipping BIOS. Hence underlying device is left in operational state. In this case scsi contoller was left with interrupt line asserted reply FIFO was not empty. When driver starts initializing in the second kernel, it receives the interrupt the moment request_irq() is called. Interrupt handler, reads the message from reply FIFO and tries to access the associated message frame and panics, as in the new kernel's context that message frame is not valid at all. o In this scenario, probably we should delay the request_irq() call. First bring up the IOC, reset it if needed and then should register for irq. o I have tested the patch with SAS1064E and 53c1030 controllers.

max_id now means the maximum number of ids on the bus, which means it is one greater than the largest possible id number. Signed-off-by: -
Amit Arora authored
The scsi_scan_host_selected() should return -EINVAL when the id is equal to the max_id. Currently it uses ">" when comparing with max_id, and hence leaves the border case when "id==max_id". The channel and lun have values valid from 0 up to, and including, max_channel or max_lun. But, the valid values for id range from 0 to max_id-1. This patch fixes the problem. Signed-off-by:

If zfcp's port erp fails we now call fc_remote_port_delete. This helps to avoid offlined scsi devices if scsi commands time out due to path failures. When an adapter erp fails we call fc_remote_port_delete for all ports on that adapter. Signed-off-by:

Do not flush queues then block session. This will cause commands to needlessly swing around on us and remove goofy recovery_failed field and replace with state value. And do not start recovery from within the host reset function. This causeis too many problems becuase open-iscsi was desinged to call out to userspace then have userpscae decide if we should go into recovery or kill the session. Signed-off-by:
