2007-05-08[SCSI] zfcp: clear adapter failed flag if an fsf request times out.Heiko Carstens1-1/+1
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.

2007-05-08[SCSI] zfcp: Fix deadlock between zfcp ERP and SCSIChristof Schmitt4-4/+72
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.

2007-05-08[SCSI] zfcp: Locking for req_no and req_seq_noChristof Schmitt1-9/+8
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.

2007-05-08[SCSI] zfcp: Stop system after memory corruptionChristof Schmitt1-28/+6
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.

2007-04-27s390: cio: Delay uevents for subchannelsCornelia Huck1-0/+6
We often have the situation that we register a subchannel and start device recognition, only to find out that the device is not usable after all, which triggers an unregister of the subchannel. This often happens on hundreds of subchannels on a LPAR, leading to a storm of events which aren't of any use. Therefore, use uevent_suppress to delay the KOBJ_ADD uevent for a subchannel until we know that its ccw_device is to be registered.

The first 32 MB of memory are saved by the hardware before the dump Linux is booted. Via an SCLP interface, the saved memory can be accessed from Linux.
