* [SCSI] megaraid_{mm,mbox}: a fix on "kernel unaligned access address" issueJu, Seokmann2006-07-28
| | | | | | | | | | | | There was an issue in the data structure defined by megaraid driver casuing "kernel unaligned access.." messages to be displayed during IOCTL on IA64 platform.

| | | | | | | | | | | With this patch, driver will protect data corruption created by INQUIRY with EVPD request to megaraid controllers. As specified in the changelog, megaraid F/W already has fixed the issue and being under process of release. Meanwhile, driver will protect the system with this patch.

* [SCSI] megaraid_{mm,mbox}: 64-bit DMA capability checkerJu, Seokmann2006-07-28
| | | | | | | | | | | | | | | | | | | This patch contains - a fix for 64-bit DMA capability check in megaraid_{mm,mbox} driver. - includes changes (going back to 32-bit DMA mask if 64-bit DMA mask failes) suggested by James with previous patch. - addition of SATA 150-4/6 as commented by Vasily Averin. With patch, the driver access PCIconfiguration space with dedicated offset to read a signature. If the signature read, it means that the controller has capability to handle 64-bit DMA. Without this patch, the driver used to blindly claim 64-bit DMA capability. The issue has been reported by Vasily Averin [vvs@sw.ru]. Thank you Vasily for the reporting.

* [SCSI] iscsi bugfixes: reduce memory allocationsMike Christie2006-07-28
| | | | | | | | | | | | | | | | | We currently try to allocate a max_recv_data_segment_length which can be very large (default is 64K), and common uses are up to 1MB. It is very very difficult to allocte this much contiguous memory and it turns out we never even use it. We really only need a couple of pages, so this patch has us allocates just what we know what we need today. Later if vendors start adding vendor specific data and we need to handle large buffers we can do this, but for the last 4 years we have not seen anyone do this or request it.

* [SCSI] iscsi bugfixes: fix oops when iser is flushing ioMike Christie2006-07-28
| | | | | | | | | | | | | When we enter recovery and flush the running commands we cannot freee the connection before flushing the commands. Some commands may have a reference to the connection that needs to be released before. iscsi_stop was forcing the term and suspend too early and was causing a oops in iser, so this patch removes those callbacks all together and allows the LLD to handle that detail.

* [SCSI] iscsi bugfixes: fix abort handlingMike Christie2006-07-28
| | | | | | | | | | | | | | | Abort handler fixes. If a connection is dropped and reconnected while an abort is running then we should assume the recovery code will clean up the abort. Not doing so causes a oops. And if a command completes then we get the status for the abort, we do not need to call into the LLD to cleanup the resources. Doing this causes and oops in iser because it ends up freeing some resources twice. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] iscsi bugfixes: handle data rsp errorsMike Christie2006-07-28
| | | | | | | | | | | | if iscsi_data_rsp fails we must bail out. Since the pdu values like data length are invalid we cannot continue to process the data since it could over run buffers.

* [SCSI] iscsi bugfixes: fix r2t handlingMike Christie2006-07-28
| | | | | | | | | | | | The iscsi tcp code can pluck multiple rt2s from the tasks's r2tqueue in the xmit code. This can result in the task being queued on the xmit queue but gettting completed at the same time. This patch fixes the above bug by making the fifo a list so we always remove the entry on the list del.

* [SCSI] sym2: claim only "Storage" classGrant Grundler2006-07-28
| | | | | | | | | | | | The follow patch fixes a problem for Matt Taggart. The Compaq system he had (dl380?) has a SmartArray device that exposes the 53c1510 device in both RAID and "normal" modes. The difference is in RAID mode, the smart array driver (IIRC) should claim the device instead of sym2 driver. Patch below prevents sym2 from claiming the device when the RAID "daughter board" is attached.

* [PATCH] fix compile regression for a few scsi driversChristoph Hellwig2006-07-26
| | | | | | | | | | | | | | | | | | | | | This fixes three drivers to compile again after my patch that removes the data_cmnd member from struct scsi_cmnd. The fas216 change is trivial, it should have been using ->cmnd all the time. NCR53C9 (which seem to be mostly duplicate driver with esp.c!) is doing something odd, it should only have looked at ->cmnd before not the saved copy that is kept for the error handlers sake. Note that it really should deal with the sync setting themselves but use the generic domain validation code that get this right - but that's for later let's push this simple compile fix for now. And sorry for the late fix for this, I have been busy with OLS and associated activities last week. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| * [SCSI] hide EH backup data outside the scsi_cmndChristoph Hellwig2006-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently struct scsi_cmnd has various fields that are used to backup original data after the corresponding fields have been overridden for EH commands. This means drivers can easily get at it and misuse it. Due to the old_ naming this doesn't happen for most of them, but two that have different names have been used wrong a lot (see previous patch). Another downside is that they unessecarily bloat the scsi_cmnd size. This patch moves them onstack in scsi_send_eh_cmnd to fix those two issues aswell as allowing future EH fixes like moving the EH command submissions to use SG lists like everything else.
