Mark Haverkamp 5d497cecde [SCSI] aacraid: regression fix
The fixes for sparse warnings mixed in with the fixups for
the raw_srb handler resulted in a bug that showed up in the 32 bit
environments when trying to issue calls directly to the physical devices
that are part of the arrays (ioctl scsi passthrough).

Received from Mark Salyzyn at adaptec.
Applied comment from Christoph to remove cpu_to_le32(0)
Applied Mark S fix of missing memcpy.
It applies to the scsi-misc-2.6 git tree.

Albert Lee 6952df0355 [PATCH] sg traverse fix for __atapi_pio_bytes()
Problem:
Incorrect md5sum when using ATAPI PIO mode to verify a distro CD.

Root cause:  sg traverse problem.
In __atapi_pio_bytes(), if qc->cursg++ is increased and "goto
next_page" is executed, then sg is not updated to the new qc->cursg
and the old sg is overwritten with the new data.

Changes:
- Replace "goto next_page" with "goto next_sg" to make sg updated.

There are several extra things that have to be considered when running
Domain Validation on a u320 target (notably how you fall back).

Hopefully this should help us when someone adds this transport class to
aic79xx.

I've tested this on the lsi1030, so I know it works correctly up to
u320.

brking@us.ibm.com 521314c122 [SCSI] sg: Command completion after remove oops
A problem exists todayin the sg driver that if an SG_IO request is
outstanding to a device when it is removed from the system. The
system may oops if that command completes later in time.

1. sg_remove gets called
2. sg_remove calls sg_finish_req_req on all pending requests
   This removes the Sg_request's from the headrp list in the Sg_fd
3. The sleeping SG_IO ioctl is woken. It does nothing and returns.
4. The caller closes the fd, which invokes sg_release
5. sg_release calls sg_remove_sfp. It finds no outstanding commands
   since the headrp list is empty, so it calls __sg_remove_sfp,
   which frees the sfp.
6. Now when sg_cmd_done gets called, sg uses upper_private_data in
   the Scsi_Request, which should point to the srp, which has been
   freed, so it points to freed memory.
7. sg then dereferences the srp pointer to get the sfp, and we oops.

The fix is to NULL out the upper_private_data field in this path,
which sg_cmd_done already checks for, which will prevent the oops
from occurring.

Nathan Lynch c92715b3c2 [SCSI] fix slab corruption during ipr probe
With CONFIG_DEBUG_SLAB=y I see slab corruption messages during boot on
pSeries machines with IPR adapters with any 2.6.12-rc kernel.

The change which seems to have introduced the problem is "SCSI: revamp
target scanning routines" and may be found at:
http://marc.theaimsgroup.com/?l=bk-commits-head&m=111093946426333&w=2

In order to revert that in a 2.6.12-rc1 tree, I had to revert "target
code updates to support scanned targets" first:
http://marc.theaimsgroup.com/?l=bk-commits-head&m=111094132524649&w=2

With both patches reverted, the corruption messages go away.

I did some digging and the problem seems to be a refcounting issue in
__scsi_add_device.  The target gets freed in scsi_target_reap, and
then __scsi_add_device tries to do another device_put on it.
