* [SCSI] replace sizeof sense_buffer with SCSI_SENSE_BUFFERSIZEFUJITA Tomonori2008-01-23
| | | | | | | | | This replaces sizeof sense_buffer with SCSI_SENSE_BUFFERSIZE in several LLDs. It's a preparation for the future changes to remove sense_buffer array in scsi_cmnd structure.

* [SCSI] aic7xxx_old, eata_pio, ips, libsas: don't zero out sense_buffer in ↵FUJITA Tomonori2008-01-23
| | | | | | | | | | | | | | | | queuecommand LLDs don't need to zero out scsi_cmnd::sense_buffer in queuecommand since scsi-ml does. This is a preparation of the future changes to allocate the sense_buffer only when necessary. Many LLDs zero out the sense_buffer before touching it on the error case. This patch lets them alone for now because new APIs for them would be added later on.

* [SCSI] aacraid: SMC vendor identificationSalyzyn, Mark2008-01-23
| | | | | | | | | | | | | | | | | | Due to an internal limit associated with the AdapterTypeText field, SMC required a product ID that overloaded the combined vendor and product ID. A decision was made to ship the SMC products without a vendor string dropping the defacto space that used to delineate vendor and product to boot. To correct this, we needed to adjust the code in the driver to parse out the vendor and product strings for the adapter. We match of 'AOC' in the AdapterTypeText, if so we set the vendor to SMC and place the entire AdapterTypeText into the product field. This only affects the cosmetic presentation of the Adapter vendor and product in the logs and in sysfs.

* [SCSI] aacraid: respond to enclosure service eventsSalyzyn, Mark2008-01-23
| | | | | | | | | | | | | Added support to respond to enclosure service events (controller AIFs) to add, online or offline physical targets reported to sg. Also added online and offlining of arrays. Removed an automatic variable definition in a sub block that hid an earlier definition, determined to be inert as the sub-block use did not interfere. Bumped the driver versioning to stamp the addition of this feature. Signed-off-by: Mark Salyzyn <aacraid@adaptec.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
* [SCSI] sym53c8xx: fixes two bugs related to chip resetKrzysztof Helt2008-01-23
| | | | | | | | | | | | | | | | | This patch fixes two bugs pointed by James Bottomley: 1. the if (!sym_data->io_reset). That variable is only ever filled by a stack based completion. If we find it non empty it means this code has been entered twice and we have a severe problem, so that should just become a BUG_ON(sym_data->io_reset). 2. sym_data->io_reset should be set to NULL before the routine is exited otherwise the PCI recovery code could end up completing what will be a bogus pointer into the stack.

* [SCSI] aacraid: improve queue balancingSalyzyn, Mark2008-01-23
| | | | | | | | | | | | | | | | | | | | The adapter queue is divided up equally to all the arrays to prevent command starvation to any individual array. On the other hand, physical targets are only granted a queue depth of one each. The code prior to this patch used to deal with the incremental discovery of targets, but the driver knows how many arrays are present prior to the scan so this knowledge is used to generate a better estimate for the queue depth. Remove the capability of 'physical=0' from preventing access to the class of adapters that have the RAID/SCSI mode of operation since none of the physicals on the SCSI channel are candidates ever for an array. As always, the user can override this default queue depth policy by making the appropriate adjustments utilizing sysfs.

* [SCSI] aacraid: OS panic after Adapter panic (hardening).Salyzyn, Mark2008-01-23
| | | | | | | | | | | | | | | | | | | | In experiments in the lab we managed to trigger an Adapter firmware panic (BlinkLED) coincidentally while several pass-through ioctl command from the management software were outstanding on a bug only present on a class of RAID Adapters that require a hardware reset rather than a commanded reset. The net result was an attempt to time out the management software command as if it came from the SCSI layer resulting in an OS panic. Adapters that use commanded reset, management commands are returned failed by the Adapter correctly. The adapter firmware panic that resulted in this condition was also resolved, and there were no adapters in the field with this specific firmware bug so we do not expect any field reports. This is a rare or unlikely corner condition, and no reports have ever been forwarded from the field.

* [SCSI] aacraid: fix big endian issuesSalyzyn, Mark2008-01-23
| | | | | | | | | | | | | | | | Big endian systems issues discovered in the aacraid driver. Somewhat reverses a patch from November 7th of last year that removed swap operations because they formerly were being assigned to an u8 array when they should have been assigned to an le32 array. This patch is largely inert for any little endian processor architecture. It resolves a bug in delivering the BlinkLED AIF event to registered applications when the adapter or associated hardware was reset due to ill health. A rare corner case occurrence, also largely unnoticed by any as it was a new (untested!) feature.

* [SCSI] scsi_transport_spi: convert to attribute groupsJames Bottomley2008-01-23
| | | | | | | | | | | This conversion makes full use of the is_visible() callback on attribute groups. Now, each device appears only with its capability flags in the transport class directory. Previously each device appeared with the capability of the host, so this is a functionality improvement.

| | | | | | | | | | | | While trying to convert the SPI transport class to attribute groups, I discovered that we don't actually have any transport configure points for either the target or the host. This patch adds these missing transport class triggers.

* [SCSI] libata: fix corruption induced by relaxed DMA alignment in SCSIJames Bottomley2008-01-23
| | | | | | | | | | | | | | | | | Hugh Dickens noticed that SMART commands issued from user space can end up corupting memory. The problem occurs if the buffer used to read data spans two pages. The reason is that the PIO sector routines in libata are expecting physically contiguous pages when they do sector operations, so the left overs on the second page go into the next physically adjacent page rather than the next page in the sg mapping. Fix this by enforcing strict 512 byte alignment on all buffers from userspace.

| | | | | | | | | | | | | | This patch relaxes the default SCSI DMA alignment from 512 bytes to 4 bytes. I remember from previous discussions that usb and firewire have sector size alignment requirements, so I upped their alignments in the respective slave allocs. The reason for doing this is so that we don't get such a huge amount of copy overhead in bio_copy_user() for udev. (basically all inquiries it issues can now be directly mapped).

| | | | | | | | | | | | | | | | | zfcp_erp_strategy_check_fsfreq() checks if it is safe to access the fsf_req associated with the erp_action that gets passed. To test if it is safe it accesses the fsf_req in order to get its index into the hash list. This is broken since the fsf_req might be freed already and the read index has no meaning. It could lead to memory corruption. Fix this by introducing a new zfcp_reqlist_find_safe() method which just checks if addresses are equal.
