SCSI: sd: handle bad lba in sense information

2008-02-26T00:14:06+00:00

patch 366c246de9cec909c5eba4f784c92d1e75b4dc38 in mainline.

Some devices report medium error locations incorrectly.  Add guards to
make sure the reported bad lba is actually in the request that caused
it.  Additionally remove the large case statment for sector sizes and
replace it with the proper u64 divisions.

esp_scsi: fix reset cleanup spinlock recursion

2007-12-14T17:51:01+00:00

patch 522939d45c293388e6a360210905f9230298df16 in mainline.

The esp_reset_cleanup() function is called with the host lock held and
invokes starget_for_each_device() which wants to take it too.  Here is a
fix along the lines of shost_for_each_device()/__shost_for_each_device()
adding a __starget_for_each_device() counterpart which assumes the lock
has already been taken.

Eventually, I think the driver should get modified so that more work is
done as a softirq rather than in the interrupt context, but for now it
fixes a bug that causes the spinlock debugger to fire.

While at it, it fixes a small number of cosmetic problems with
starget_for_each_device() too.

        [SCSI] dpt_i2o: convert to SCSI hotplug model

         - Delete refereces to HOSTS_C
         - Switch to module_init/module_exit instead of detect/release
         - Don't pass around the host template and rename it to adpt_template
         - Switch from scsi_register/scsi_unregister to scsi_host_alloc,
           scsi_add_host, scsi_scan_host and scsi_host_put.

Because it caused (for unknown reasons) Andres' all-data-reads-as-zeroes
problem, reported at

hptiop: avoid buffer overflow when returning sense data

2007-11-16T17:30:24+00:00

patch 0fec02c93f60fb44ba3a24a0d3e4a52521d34d3f in mainline.

avoid buffer overflow when returning sense data.

With current adapter firmware the driver is working but future firmware
updates may return sense data larger than 96 bytes, causing overflow on
scp->sense_buffer and a kernel crash.

This fix should be backported to earlier kernels.

[SCSI] megaraid_old: fix READ_CAPACITY

2007-10-04T16:08:49+00:00

The bulk transfer mode got eleminated by
3f6270ef76f2ce5c134615a470685d6c2a66c07e.  Unfortunately, this mode is
required for READ_CAPACITY commands on certain cards, so put it back
again.  This fixes a boot failure regression reported by Burton
Windle.

[SCSI] esp: fix instance numbering.

2007-09-26T01:55:02+00:00

Because the ->unique_id is set too late, the ESP scsi host
instance numbers in the kernel log during probing are
wrong.

[SCSI] scsi_transport_spi: fix domain validation failure from incorrect width setting

2007-09-22T13:52:12+00:00

Domain Validation in the SPI transport class is failing on boxes with
damaged cables (and failing to the extent that the box hangs).  The
problem is that the first test it does is a cable integrity test for
wide transfers and if this fails, it turns the wide bit off.  The
problem is that the next set of tests it does turns wide back on
again, with the result that it runs through the entirety of DV with a
known bad setting and then hangs the system.

The attached patch fixes the problem by physically nailing the wide
setting to what it deduces it should be for the whole of Domain
Validation.
