Pull SCSI fixes from James Bottomley:
"This is really three fixes, but the SES one comes in a bundle of three
(making the replacement API available properly, using it and removing
the non-working one). The SES problem causes an oops on hpsa devices
because they attach virtual disks to the host which aren't SAS
attached (the replacement API ignores them).
The other two fixes are fairly minor: the sense key one means we
actually resolve a newly added sense key and the RDAC device
blacklisting is needed to prevent us annoying the universal XPORT lun
of various RDAC arrays"

As there are no more users of is_sas_attached() left, remove it.

Use scsi_is_sas_rphy() instead of is_sas_attached() to decide whether we
should obtain the SAS address from a scsi device or not. This will
prevent us from tripping on the BUG_ON() in sas_sdev_to_rdev() if the
rphy isn't attached to the SAS transport class, like it is with hpsa's
logical devices.

Currently we free the resources backing the enclosure device before we
call device_unregister(). This is racy: during rmmod of low-level SCSI
drivers that hook into enclosure, we end up with a small window of time
during which writing to /sys can OOPS. Example trace with mpt3sas:
general protection fault: 0000 [#1] SMP KASAN
Modules linked in: mpt3sas(-) <...>
RIP: [<ffffffffa0388a98>] ses_get_page2_descriptor.isra.6+0x38/0x220 [ses]

Fortunately the solution is extremely simple: call device_unregister()
before we free the resources, and the race no longer exists. The driver
core holds a reference over ->remove_dev(), so AFAICT this is safe.

It turns out megasas_init_fw() etc are using bar index as mask. index 1

request BAR0 instead of BAR1.

In aacraid's ioctl_send_fib() we do two fetches from userspace, one the
get the fib header's size and one for the fib itself. Later we use the
size field from the second fetch to further process the fib. If for some
reason the size from the second fetch is different than from the first
fix, we may encounter an out-of- bounds access in aac_fib_send(). We
also check the sender size to insure it is not out of bounds. This was
reported in https://bugzilla.kernel.org/show_bug.cgi?id=116751 and was
assigned CVE-2016-6480.

If an EEH or some other hard error occurs while the adapter instance was

could crash with:

This crash is due to the AFU not being mapped when the shutdown
notification routine is called and is a regression that was inserted
recently with Commit 704c4b0ddc03 ("cxlflash: Shutdown notify support
for CXL Flash cards").
As a fix, shutdown notification should only occur when the AFU is
mapped.

The lpfc_sli4_scmd_to_wqidx_distr() function expects the scsi_cmnd
'lpfc_cmd->pCmd' not to be null, and point to the midlayer command.
That's not true in the .eh_(device|target|bus)_reset_handler path,
because lpfc_send_taskmgmt() sends commands not from the midlayer, so
does not set 'lpfc_cmd->pCmd'.
That is true in the .queuecommand path because lpfc_queuecommand()
stores the scsi_cmnd from midlayer in lpfc_cmd->pCmd; and lpfc_cmd is
stored by lpfc_scsi_prep_cmnd() in piocbq->context1 -- which is passed
to lpfc_sli4_scmd_to_wqidx_distr() as lpfc_cmd parameter.
This problem can be hit on SCSI EH, and immediately with sg_reset.
These 2 test-cases demonstrate the problem/fix with next-20160601.

Pull SCSI target updates from Nicholas Bellinger:
"The most notable item is IBM virtual SCSI target driver, that was
originally ported to target-core back in 2010 by Tomo-san, and has
been brought forward to v4.x code by Bryant Ly, Michael Cyr and co
over the last months.
Also included are two ORDERED task related bug-fixes Bryant + Michael
found along the way using ibmvscsis with AIX guests, plus a few
miscellaneous target-core + iscsi-target bug-fixes with associated
stable tags"
* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
target: fix spelling mistake: "limitiation" -> "limitation"
target: Fix residual overflow handling in target_complete_cmd_with_length
tcm_fc: set and unset FCP_SPPF_TARG_FCN
iscsi-target: Fix panic when adding second TCP connection to iSCSI session
ibmvscsis: Initial commit of IBM VSCSI Tgt Driver
target: Fix ordered task CHECK_CONDITION early exception handling
target: Fix ordered task target_setup_cmd_from_cdb exception hang

This driver is a pick up of the old IBM VIO scsi Target Driver
that was started by Nick and Fujita 2-4 years ago.
http://comments.gmane.org/gmane.linux.scsi/90119
The driver provides a virtual SCSI device on IBM Power Servers.
This patch contains the fifth version for an initial merge of the
tcm ibmvscsis driver. More information on this driver and config
can be found:

Remove the CXL_KERNEL_API and CXL_EEH Kconfig options, as they were only
needed to coordinate the merging of the cxlflash driver. Also remove the
stub implementation of cxl_perst_reloads_same_image() in cxlflash which is
only used if CXL_EEH isn't defined (i.e. never).

That macros uses logical "&&" instead of bit-wise "&" which is
apparently wrong. Since the macro is completely unused, simply
remove it, so that nobody can accidentially use it anymore.

When building with -Wextra, we get a lot of warnings for the lpfc driver
concerning expressions that are always true, starting with:
drivers/scsi/lpfc/lpfc_attr.c: In function 'lpfc_enable_npiv_init':
drivers/scsi/lpfc/lpfc_attr.c:2786:77: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits]
drivers/scsi/lpfc/lpfc_attr.c: In function 'lpfc_enable_rrq_init':
drivers/scsi/lpfc/lpfc_attr.c:2802:76: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits]
drivers/scsi/lpfc/lpfc_attr.c: In function 'lpfc_suppress_link_up_init':
drivers/scsi/lpfc/lpfc_attr.c:2812:2050: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits]
drivers/scsi/lpfc/lpfc_attr.c: In function 'lpfc_log_verbose_init':
drivers/scsi/lpfc/lpfc_attr.c:3064:1930: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits]
The code works as intended, but it would be nice to shut up the warning
so we don't clutter up build logs with this. Using a separate inline
function for it makes it clear to the compiler that the comparison is
necessary in the caller but still lets it do the constant-folding.

When running in VN2VN mode there is no central instance which would send
out any FIP VLAN discovery notifications. So this patch adds a new sysfs
attribute 'fip_vlan_responder' which will activate a FIP VLAN discovery
responder.

When buff_ascii kmalloc failed, there is no need to call kfree, it
should return -ENOMEM directly, this patch fixes it.

The SA controller spins down RAID drive spares.
A REGNEWD event causes an inquiry to be sent to all physical
drives. This causes the SA controller to spin up the spare.
The controller suspends all I/O to a logical volume until
the spare is spun up. The spin-up can take over 50 seconds.
This can result in one or both of the following:
- SML sends down aborts and resets to the logical volume
and can cause the logical volume to be off-lined.
- a negative impact on the logical volume's I/O performance
each time a REGNEWD is triggered.

If there is error recovery going on due to command timeout and
there is register disconnect, then disable the adapter.
