Must clear adapter failed flag if an fsf request times out. This is necessary because on link down situations the failed flags gets set but the QDIO queues are still up. Since an adapter reopen will be skipped if the failed flag is set an adapter_reopen that is issued on fsf request timeout has no effect if the local link is down. Might lead to locked up system if the SCSI stack is waiting for abort completion. Signed-off-by:

The SCSI stack requires low level drivers to register and unregister devices. For zfcp this leads to the situation where zfcp calls the SCSI stack, the SCSI tries to scan the new device and the scan SCSI command fails. This would require the zfcp erp, but the erp thread is already blocked in the register call. The fix is to make sure that the calls from the ERP thread to the SCSI stack do not block the ERP thread. In detail: 1) Use a workqueue to avoid blocking of the scsi_scan_target calls. 2) When removing a unit make sure that no scsi_scan_target call is pending. 3) Replace scsi_flush_work with scsi_target_unblock. This avoids blocking and has the same result. Signed-off-by:

There is a possible race condition while generating the unique request ids and sequence numbers. Both might be read at the same time and have the same value. Fix this by serializing the access through the queue lock of the adapter: First call zfcp_fsf_req_sbal_get that acquires the lock, then read and increment the unique ids. Signed-off-by:

Use a newly added PCI API to issue a PCI Fundamental reset (warm reset) to a new ipr PCI-E adapter. Typically, the ipr adapter uses the start BIST bit in config space to reset an adapter. Issuing start BIST on this particular adapter results in the PCI-E logic on the card losing sync, which causes PCI-E errors, making the card unusable. The only reset mechanism that exists on this hardware that does not have this problem is PCI Fundamental reset (warm reset). Signed-off-by:

For each request that is sent to the FCP adapter, zfcp allocates memory. Status information and data that is being read from the device is written to this memory by the hardware. After that, the hardware signals this via the response queue and zfcp continues processing. Now, if zfcp detects that there is a signal for an incoming response from the hardware, but there is no outstanding request for that request id, then some memory that can be in use anywhere in the system has just been overwritten. This should never happen, but if it does, stop the system with a panic. Signed-off-by:

The kexec patch introduced a superfluous (and otherwise inert) reset of some adapters. The register can have a hardware default value that has zeros for the undefined interrupts. This patch refines the test of the interrupt enable register to focus on only the interrupts that affect the driver in order to detect if an incomplete shutdown of the Adapter had occurred (kdump).

cpu_to_le32 endianness conversions in tmscsim.c, followed by arithmetic operations don't look correct. Besides, {in,out}[wl] already perform the necessary conversions. Further, bus addresses of request buffers are guaranteed to be (mapped) under 4G by current scsi- and block-layer defaults. This could be explicitly enforced by using blk_queue_bounce_limit(), which, however, doesn't seem to be the common practice among SCSI drivers. Signed-off-by: -

If an ipr adapter encounters an adapter error requiring an adapter reset to recover from prior to driver load time, the error will be ignored and recovery will not happen until the initial timeout occurs waiting for the firmware to come ready, which means a five minute timeout. Fix is to read the interrupt register before clearing any of the interrupts at probe time. Signed-off-by:

Now that we have the much better esp_scsi driver and low level drivers are easy to port over deprecate the old NCR53C9x driver. I've Cc'ed the m68k and mips lists because all but one bus glues are for these platforms. Chances stand bad for the remaining driver, mca_53c9x which hasn't gotten any non-trivial update since it was merge in late 2.1.x and whos maintainers mail address bounces. Signed-off-by:

Per the comment in the change - it's not always prudent to immediately remove the rport upon first notice of a disconnect. Make all rports wait dev_loss_tmo before being deleted (and each could have a separate dev_loss_tmo value). The original post was: http://marc.info/?l=linux-scsi&m=117392196006703&w=2 The repost contains the following changes: - Bug fix in fc_starget_delete(). Dev_loss_tmo_callbk() was called prior to tearing down the target. The callback is to be the last thing called, as it tells the LLDD that the rport is completely finished and can be torn down. Rework so that terminate_rport_io() is called to terminate the outstanding io. Isolated work so it's is simply "starget" work. - Fix holes in original patch. There were code paths that did not expect the dev_loss_tmo timer to be running for the non-fcp rports. - Bug Fix: the transport wasn't protecting against a LLDD calling fc_remote_port_delete() back-to-back. Thus, the dev_loss_tmo timer could be restarted such that it fires after the rport had been deleted. Validate rport state before starting the timer. Signed-off-by:
