Instead of strcpy'ing into a stack buffer, just let additional_notice point
to a string literal living in .rodata. This is better in a few ways:
- Smaller .text - instead of gcc compiling the strcpys as a bunch of
immediate stores (effectively encoding the string literal in the
instruction stream), we only pay the price of storing the literal in
.rodata.
- Faster, because there's no string copying.
- Smaller stack usage (with my compiler, 72 bytes instead of 176 for the
sole caller, bnx2i_indicate_kcqe)
Moreover, it's currently possible for additional_notice[] to get used
uninitialized, so some random stack garbage would be passed to printk() -
in the worst case without any '\0' anywhere in those 64 bytes. That could
be fixed by initializing additional_notice[0], but the same is achieved
here by initializing the new pointer variable to "".
Also give the message pointer a similar treatment - there's no point making
temporary copies on the stack of those two strings.

Calling vha->hw->tgt.tgt_ops->free_cmd() from qlt_xmit_response() is wrong
since the command for which a response is sent must remain valid until the
SCSI target core calls .release_cmd(). It has been observed that the
following scenario triggers a kernel crash:
- qlt_xmit_response() calls qlt_check_reserve_free_req()
- qlt_check_reserve_free_req() returns -EAGAIN
- qlt_xmit_response() calls vha->hw->tgt.tgt_ops->free_cmd(cmd)
- transport_handle_queue_full() tries to retransmit the response
Fix this crash by reverting the patch that introduced it.

During MQ enablement of the ibmvfc driver ibmvfc_wait_for_ops() was
missed. This function is responsible for waiting on commands to complete
that match a certain criteria such as LUN or cancel key. The implementation
as is only scans the CRQ for events ignoring any sub-queues and as a result
will exit successfully without doing anything when operating in MQ
channelized mode.
Check the MQ and channel use flags to determine which queues are
applicable, and scan each queue accordingly. Note in MQ mode SCSI commands
are only issued down sub-queues and the CRQ is only used for driver
specific management commands. As such the CRQ events are ignored when
operating in MQ mode with channels.

For various EH activities the ibmvfc driver uses ibmvfc_wait_for_ops() to
wait for the completion of commands that match a given criteria be it
cancel key, or specific LUN. With recent changes commands are completed
outside the lock in bulk by removing them from the sent list and adding
them to a private completion list. This introduces a potential race in
ibmvfc_wait_for_ops() since the criteria for a command to be outstanding is
no longer simply being on the sent list, but instead not being on the free
list.
Avoid this race by scanning the entire command event pool and checking that
any matching command that ibmvfc needs to wait on is not already on the
free list.

There are similar code implementations for WB configuration in
ufshcd_wb_{ctrl, toggle_flush_during_h8, toggle_flush}. Extract the common
parts to create a new helper with a flag parameter to reduce code
duplication.
Meanwhile, rename ufshcd_wb_ctrl() to ufshcd_wb_toggle() for better
readability. And remove unnecessary log messages from ufshcd_wb_config()
since relevant toggle function will emit messages. Also change
ufshcd_wb_toggle_flush{__during_h8} to void type accordingly.

storvsc currently sets .dma_boundary to limit scatterlist entries to 4
Kbytes, which is less efficient with huge pages that offer large chunks of
contiguous physical memory. Improve the algorithm for creating the Hyper-V
guest physical address PFN array so that scatterlist entries with lengths >
4Kbytes are handled. As a result, remove the .dma_boundary setting.
The improved algorithm also adds support for scatterlist entries with
offsets >= 4Kbytes, which is supported by many other SCSI low-level
drivers. And it retains support for architectures where possibly PAGE_SIZE
!= HV_HYP_PAGE_SIZE (such as ARM64).

The buffer for negotiating channel setup is DMA allocated at device probe
time. However, the remove path fails to free this allocation which will
prevent the hypervisor from releasing the virtual device in the case of a
hotplug remove.
Fix this issue by freeing the buffer allocation in ibmvfc_free_mem().

On a setup with a dual port HBA and both ports direct connected, an rmmod
hangs momentarily when we log an Illegal State Transition. Once it resumes,
a nodelist not empty logic is hit, which forces rmmod to cleanup and exit.
We're missing a state transition case in the discovery engine.
Fix by adding a case for a DEVICE_RM event while in the unmapped state to
avoid illegal state transition log message.

While testing target port swap test with ADISC enabled, several nodes
remain in UNUSED state. These nodes are never freed and rmmod hangs for
long time before finising with "0233 Nodelist not empty" error.
During PLOGI completion lpfc_plogi_confirm_nport() looks for existing nodes
with same WWPN. If found, the existing node is used to continue discovery.
The node on which plogi was performed is freed. When ADISC is enabled, an
ADISC els request is triggered in response to an RSCN. It's possible that
the ADISC may be rejected by the remote port causing the ADISC completion
handler to clear the port and node name in the node. If this occurs, if a
PLOGI is received it causes a node lookup based on wwpn to now fail,
causing the port swap logic to kick in which allocates a new node and swaps
to it. This effectively orphans the original node structure.
Fix the situation by detecting when the lookup fails and forgo the node
swap and node allocation by using the node on which the PLOGI was issued.

When connected in pt2pt mode, there is a scenario where the remote port
significantly delays sending a response to our FLOGI, but acts on the FLOGI
it sent us and proceeds to PLOGI/PRLI. The FLOGI ends up timing out and
kicks off recovery logic. End result is a lot of unnecessary state changes
and lots of discovery messages being logged.
Fix by terminating the FLOGI and noop'ing its completion if we have already
accepted the remote ports FLOGI and are now processing PLOGI.

There are several code paths where the following sequence occurs:
- An ndlp pointer is assigned to an iocb via a nlp_get()
- An attempt is made to issue the iocb, but it fails
- The failure case does a put on the ndlp then calls lpfc_els_free_iocb()
The put may free the ndlp structure, but the els_free_iocb may reference
the now-stale ndlp pointer and cause a crash.
Fix by ensuring that the lpfc_els_free_iocb() occurs before the
lpfc_nlp_put().
While fixing, refactor the code to better ensure this calling sequence.

lpfc_fcp_io_cmd_wqe_cmpl() is intended to mirror
lpfc_nvme_io_cmd_wqe_cmpl() for sli4 fcp completions. When the routine was
added, lpfc_fcp_io_cmd_wqe_cmpl() included a null pointer check for
phba. However, phba is definitely valid, being dereferenced by the calling
routine and used later in the routine itself.
Remove the unnecessary null check.

After an initial successful FLOGI into the switch, if a subsequent FLOGI
fails the driver crashed accessing a node struct. On FLOGI error, the flogi
completion logic triggers the final dereference on the node structure
without checking if it is registered with a backend. The devloss logic is
triggered after node is freed leading to the access of freed node.
Fix by adjusting the error path to not take the final dereferece if there
is an outstanding transport registration. Let the transport devloss call
remove the final reference.

Whenever an RRQ needs to be triggered, the DID from the node structure and
node pointer are stored in the RRQ data structure and the RRQ is scheduled
for later transmission. However, at the point in time that the timer
triggers, there's no validation on the node pointer. Reference counters may
have freed the structure. Additionally the DID in the node may no longer be
valid.
Fix by not tracking the node pointer in the RRQ, only the DID. At the time
of the timer expiration, look up the node with the did and if present, send
the RRQ. If no node exists, no need to send the RRQ.

An LBA is 8 bytes. The driver generates a reftag from the LBA but the

our reftag size.
Fix by converting all the code to calling the common routine
t10_pi_ref_tag() which returns a u32, thus ensuring a consistent 4byte
value. Also correct a few code lines that access LBA directly and ensure
64-bit data types are used.

Add a new sdeb_defer_type enumeration: SDEB_DEFER_POLL for requests that
have REQ_HIPRI set in cmd_flags field. It is expected that these requests
will be polled via the mq_poll entry point which is driven by calls to
blk_poll() in the block layer. Therefore timer events are not 'wired up' in
the normal fashion.
There are still cases with short delays (e.g. < 10 microseconds) where by
the time the command response processing occurs, the delay is already
exceeded in which case the code calls scsi_done() directly. In such cases
there is no window for mq_poll() to be called.
Add 'mq_polls' counter that increments on each scsi_done() called via the
mq_poll entry point. Can be used to show (with 'cat
/proc/scsi/scsi_debug/<host_id>') that blk_poll() is causing completions
rather than some other mechanism.

SCSI currently uses an atomic variable to track queue depth for each
attached device. The queue depth depends on many factors such as transport
type and device implementation. In addition, the SCSI device queue depth is
not a static entity but changes over time as a result of congestion
management.
While blk-mq currently tracks queue depth for each hctx, it can't easily be
changed to accommodate the SCSI per-device requirement.
The current approach of using an atomic variable doesn't scale well when
there are lots of CPU cores and the disk is very fast. IOPS can be
substantially impacted by the atomic in the hot path.
Replace the atomic variable sdev->device_busy with an sbitmap for tracking
the SCSI device queue depth.
It has been observed that IOPS is improved ~30% by this patchset in the
following test:
1) test machine(32 logical CPU cores)
Thread(s) per core: 2
Core(s) per socket: 8
Socket(s): 2
NUMA node(s): 2
Model name: Intel(R) Xeon(R) Silver 4110 CPU @ 2.10GHz
2) setup scsi_debug:
modprobe scsi_debug virtual_gb=128 max_luns=1 submit_queues=32 delay=0 max_queue=256
3) fio script:
fio --rw=randread --size=128G --direct=1 --ioengine=libaio --iodepth=2048 \
--numjobs=32 --bs=4k --group_reporting=1 --group_reporting=1 --runtime=60 \

Limit SCSI device's queue depth to max(host->can_queue, 1024) in
scsi_change_queue_depth(). 1024 is big enough for saturating current fast
SCSI LUN(SSD or RAID volume on multiple SSDs). Also single hardware queue
depth is usually enough for saturating single LUN because per-core
performance is often considered in storage design.
This patch is needed for replacing sdev->device_busy with sbitmap which has

Currently, exception event status can be read from wExceptionEventStatus
attribute (sysfs file attributes/exception_event_status under the UFS host
controller device directory). Polling that attribute to track UFS exception
events is impractical, so add a tracepoint to track exception events for
testing and debugging purposes.
Note, by the time the exception event status is read, the exception event

Note also, only enabled exception events can be reported. A subsequent

A live partition migration (LPM) results in a CRQ disconnect similar to a
hard reset. In this LPM case the hypervisor mostly preserves the CRQ
transport such that it simply needs to be reenabled. However, the
capabilities may have changed such as fewer channels, or no channels at
all. Further, its possible that there may be sub-CRQ support, but no
channel support. The CRQ reenable path currently doesn't take any of this
into consideration.
For simplicity release and reinitialize sub-CRQs during reenable, and set
do_enquiry and using_channels with the appropriate values to trigger
channel renegotiation.

A non-zero return code for H_REG_SUB_CRQ is currently treated as a failure
resulting in failing sub-CRQ setup. The case of H_CLOSED should not be
treated as a failure. This return code translates to a successful sub-CRQ
registration by the hypervisor, and is meant to communicate back that there
is currently no partner VIOS CRQ connection established as of yet. This is
a common occurrence during a disconnect where the client adapter can
possibly come back up prior to the partner adapter.
For non-zero return code from H_REG_SUB_CRQ treat a H_CLOSED as success so
that sub-CRQs are successfully setup.

A hard reset results in a complete transport disconnect such that the CRQ
connection with the partner VIOS is broken. This has the side effect of
also invalidating the associated sub-CRQs. The current code assumes that
the sub-CRQs are perserved resulting in a protocol violation after trying
to reconnect them with the VIOS. This introduces an infinite loop such that
the VIOS forces a disconnect after each subsequent attempt to re-register
with invalid handles.
Avoid the aforementioned issue by releasing the sub-CRQs prior to CRQ
disconnect, and driving a reinitialization of the sub-CRQs once a new CRQ
is registered with the hypervisor.

If ibmvfc_init_sub_crqs() fails ibmvfc_probe() simply parrots registration
failure reported elsewhere, and futher vhost->scsi_scrq.scrq == NULL is
indication enough to the driver that it has no sub-CRQs available. The
mq_enabled check can also be moved into ibmvfc_init_sub_crqs() such that
each caller doesn't have to gate the call with a mq_enabled check. Finally,
in the case of sub-CRQ setup failure setting do_enquiry can be turned off
to putting the driver into single queue fallback mode.
The aforementioned changes also simplify the next patch in the series that
fixes a hard reset issue, by tying a sub-CRQ setup failure and do_enquiry
logic into ibmvfc_init_sub_crqs().

The driver core ignores the return value of struct bus_type::remove()
because there is only little that can be done. To simplify the quest to
make this function return void, let struct vio_driver::remove() return
void, too. All users already unconditionally return 0, this commit makes
it obvious that returning an error code is a bad idea.
Note there are two nominally different implementations for a vio bus:
one in arch/sparc/kernel/vio.c and the other in
arch/powerpc/platforms/pseries/vio.c. This patch only adapts the powerpc
one.
Before this patch for a device that was bound to a driver without a
remove callback vio_cmo_bus_remove(viodev) wasn't called. As the device
core still considers the device unbound after vio_bus_remove() returns
calling this unconditionally is the consistent behaviour which is
implemented here.

Prevent incrementing device->commands_outstanding for ioaccel command
retries that are driver initiated. If the command goes through the retry
path, the device->commands_outstanding counter has already accounted for
the number of commands outstanding to the device. Only commands going
through function hpsa_cmd_resolve_events decrement this counter.
- ioaccel commands go to either HBA disks or to logical volumes comprised
of SSDs.
The extra increment is causing device resets to hang.
- Resets wait for all device outstanding commands to complete before
returning.
Replace unused field abort_pending with retry_pending. This is a
maintenance driver so these changes have the least impact/risk.

Dan reported we're passing in GFP_NOIO to kvmalloc() which will then
fallback to doing kmalloc() instead of an optional vmalloc() if the size
exceeds kmalloc()s limits. This will break with drives that have zone
numbers exceeding PAGE_SIZE/sizeof(u32).
Instead of passing in GFP_NOIO, enter an implicit GFP_NOIO allocation
scope.

For host-aware ZBC disk, setting the device zoned model to BLK_ZONED_HA
using blk_queue_set_zoned() in sd_read_block_characteristics() may
result in the block device effective zoned model to be "none"
(BLK_ZONED_NONE) if partitions are present on the device. In this case,
sd_zbc_read_zones() should not setup the zone related queue limits for
the disk so that the device limits and configuration is consistent with
a regular disk and resources not uselessly allocated (e.g. the zone
write pointer tracking array for zone append emulation).
Furthermore, if the disk zoned model changes at run time due to the
creation of a partition by the user, the zone related resources can be
released.
Fix both problems by introducing the function sd_zbc_clear_zone_info()
to reset the scsi disk zone information and free resources and by
returning early in sd_zbc_read_zones() for a block device that has a
zoned model equal to BLK_ZONED_NONE.

Per ZBC and ZAC specifications, host-managed SMR hard-disks mandate that
all writes into sequential write required zones be aligned to the device
physical block size. However, NVMe ZNS does not have this constraint and
allows write operations into sequential zones to be aligned to the
device logical block size. This inconsistency does not help with
software portability across device types.
To solve this, introduce the zone_write_granularity queue limit to
indicate the alignment constraint, in bytes, of write operations into
zones of a zoned block device. This new limit is exported as a
read-only sysfs queue attribute and the helper
blk_queue_zone_write_granularity() introduced for drivers to set this
limit.
The function blk_queue_set_zoned() is modified to set this new limit to
the device logical block size by default. NVMe ZNS devices as well as
zoned nullb devices use this default value as is. The scsi disk driver
is modified to execute the blk_queue_zone_write_granularity() helper to
set the zone write granularity of host-managed SMR disks to the disk
physical block size.
The accessor functions queue_zone_write_granularity() and
bdev_zone_write_granularity() are also introduced.

The session lock in iscsi_session_chkready() is not needed because when we
transition from logged into to another state we will block and/or remove
the devices under the session, so no new I/O will be sent to the drivers
after the block/remove. I/O that races with the block/removal is cleaned up
by the drivers when it handles all outstanding I/O, so this just added an
extra lock in the main I/O path. This patch removes the lock like other
transport classes.

If we lose the session then relogin, but the new cmdsn window has shrunk
(due to something like an admin changing a setting) we will have the old
exp/max_cmdsn values and will never be able to update them. For example,
max_cmdsn would be 64, but if on the target the user set the window to be
smaller then the target could try to return the max_cmdsn as 32. We will
see that new max_cmdsn in the rsp but because it's lower than the old
max_cmdsn when the window was larger we will not update it.
So this patch has us reset the window values during session cleanup so they
can be updated after a new login.

The following bug was reported and debugged by wubo40@huawei.com:
When testing kernel 4.18 version, NULL pointer dereference problem occurs
in iscsi_eh_cmd_timed_out() function.
I think this bug in the upstream is still exists.
The analysis reasons are as follows:
1) For some reason, I/O command did not complete within the timeout
period. The block layer timer works, call scsi_times_out() to handle I/O
timeout logic. At the same time the command just completes.
2) scsi_times_out() call iscsi_eh_cmd_timed_out() to process timeout logic.
Although there is an NULL judgment for the task, the task has not been
released yet now.
3) iscsi_complete_task() calls __iscsi_put_task(). The task reference count
reaches zero, the conditions for free task is met, then
iscsi_free_task() frees the task, and sets sc->SCp.ptr = NULL. After
iscsi_eh_cmd_timed_out() passes the task judgment check, there can still
be NULL dereference scenarios.

To prevent this, we take a ref to the cmd under the back (completion) lock
so if the completion side were to call iscsi_complete_task() on the task
while the timer/eh paths are not holding the back_lock it will not be freed
from under us.
Note that this requires the previous patch, "scsi: libiscsi: Drop
taskqueuelock" because bnx2i sleeps in its cleanup_task callout if the cmd
is aborted. If the EH/timer and completion path are racing we don't know
which path will do the last put. The previous patch moved the operations we
needed to do under the forward lock to cleanup_queued_task. Once that has
run we can drop the forward lock for the cmd and bnx2i no longer has to
worry about if the EH, timer or completion path did the ast put and if the
forward lock is held or not since it won't be.

The purpose of the taskqueuelock was to handle the issue where a bad target
decides to send a R2T and before its data has been sent decides to send a
cmd response to complete the cmd. The following patches fix up the
frwd/back locks so they are taken from the queue/xmit (frwd) and completion
(back) paths again. To get there this patch removes the taskqueuelock which
for iSCSI xmit wq based drivers was taken in the queue, xmit and completion
paths.
Instead of the lock, we just make sure we have a ref to the task when we
queue a R2T, and then we always remove the task from the requeue list in
the xmit path or the forced cleanup paths.

If iscsi_prep_scsi_cmd_pdu() fails we try to add it back to the cmdqueue,
but we leave it partially setup. We don't have functions that can undo the
pdu and init task setup. We only have cleanup_task which can clean up both
parts. So this has us just fail the cmd and go through the standard cleanup
routine and then have the SCSI midlayer retry it like is done when it fails
in the queuecommand path.

MPT Fusion adapters can steer completions to individual queues and we now
have support for shared host-wide tags in the I/O stack. The addition of
the host-wide tags allows us to enable multiqueue support for MPT Fusion
adapters. Once host-wise tags are enabled, the CPU hotplug feature is also
supported.
Allow use of host-wide tags to be disabled through the "host_tagset_enable"
module parameter. Once we do not have any major performance regressions
using host-wide tags, we will drop the hand-crafted interrupt affinity
settings.
Performance is meeting expectations. About 3.1M IOPS using 24 Drive SSD on
Aero controllers.

Currently the driver allocates memory for ReplyPostFree queues in chunks of
16. In resource constrained environments--such as VM with 1 GB RAM and 2
CPUs--memory allocation for ReplyPostFree pools may fail because the driver
tries to allocate a memory for 16 ReplyPostFree queues even though the
actual number needed is 2.
Change the driver to allocate memory for only the actual number of queues
needed if the ReplyPostFree queue count is less than 16.

Building with 'make W=1' enables -Wpacked-not-aligned, and this warns about
pmcraid because of incompatible alignment constraints for
pmcraid_passthrough_ioctl_buffer:
drivers/scsi/pmcraid.h:1044:1: warning: alignment 1 of 'struct pmcraid_passthrough_ioctl_buffer' is less than 32 [-Wpacked-not-aligned]
1044 | } __attribute__ ((packed));
| ^
drivers/scsi/pmcraid.h:1041:24: warning: 'ioarcb' offset 16 in 'struct pmcraid_passthrough_ioctl_buffer' isn't aligned to 32 [-Wpacked-not-aligned]
1041 | struct pmcraid_ioarcb ioarcb;
The inner structure is documented as having 32 byte alignment here, but is
starts at a 16 byte offset in the outer structure, so it's never actually
aligned, as the outer structure is also marked 'packed'.
Lee Jones point this out as one of the last files that need to be changed
before the warning can be enabled by default.
Change the annotations in a way that avoids the warning but leaves the
layout unchanged, by removing the packing on the inner structure and adding
it to the outer one. The one-byte request_buffer[] array should have been a
flexible array member here, which is how I change it to avoid extra padding
from the alignment attribute.
