40fa7394a1 scsi: pm80xx: Fix potential infinite loop
The for-loop iterates with a u8 loop counter i and compares this with the
loop upper limit of pm8001_ha->max_q_num which is a u32 type.  There is a
potential infinite loop if pm8001_ha->max_q_num is larger than the u8 loop
counter. Fix this by making the loop counter the same type as
pm8001_ha->max_q_num.

[mkp: this is purely theoretical, max_q_num is currently limited to 64]

6f305bf699 scsi: pm80xx: Remove busy wait from mpi_uninit_check()
mpi_uninit_check() is not being called in an atomic context.  The only
caller of mpi_uninit_check() is pm80xx_chip_soft_rst().

 - pm8001_ioctl_soft_reset()
 - pm8001_pci_probe()
 - pm8001_pci_remove()
 - pm8001_pci_suspend()
 - pm8001_pci_resume()

3f744a14f3 scsi: pm80xx: Increase timeout for pm80xx mpi_uninit_check()
The mpi_uninit_check() takes longer for inbound doorbell register to be
cleared. Increase the timeout substantially so that the driver does not
fail to load.

Previously, the inbound doorbell wait time was mistakenly increased in the
mpi_init_check() instead of mpi_uninit_check(). It is okay to leave the
mpi_init_check() wait time as-is as these are timeout values and if there
is a failure, waiting longer is not an issue.

176ddd8917 scsi: libsas: Reset num_scatter if libata marks qc as NODATA
When the cache_type for the SCSI device is changed, the SCSI layer issues a
MODE_SELECT command. The caching mode details are communicated via a
request buffer associated with the SCSI command with data direction set as
DMA_TO_DEVICE (scsi_mode_select()). When this command reaches the libata
layer, as a part of generic initial setup, libata layer sets up the
scatterlist for the command using the SCSI command (ata_scsi_qc_new()).
This command is then translated by the libata layer into
ATA_CMD_SET_FEATURES (ata_scsi_mode_select_xlat()). The libata layer treats
this as a non-data command (ata_mselect_caching()), since it only needs an
ATA taskfile to pass the caching on/off information to the device. It does
not need the scatterlist that has been setup, so it does not perform
dma_map_sg() on the scatterlist (ata_qc_issue()). Unfortunately, when this
command reaches the libsas layer (sas_ata_qc_issue()), libsas layer sees it
as a non-data command with a scatterlist. It cannot extract the correct DMA
length since the scatterlist has not been mapped with dma_map_sg() for a
DMA operation. When this partially constructed SAS task reaches pm80xx
LLDD, it results in the following warning:

"pm80xx_chip_sata_req 6058: The sg list address
start_addr=0x0000000000000000 data_len=0x0end_addr_high=0xffffffff
end_addr_low=0xffffffff has crossed 4G boundary"

Update libsas to handle ATA non-data commands separately so num_scatter and
total_xfer_len remain 0.

and that patch ended up resetting the state during conn stoppage and using
the wrong state value during ep_disconnect. This patch moves the setting of
the class state to the class module and then fixes the two issues above.

To remove the last user of the unchecked_isa_dma flag and thus the block

buffer.  This has the effect of not needing the chain indirection and

transfer size for each command to something that can be reasonable
allocated by dma_alloc_coherent like 8K.

1352eec8c0 scsi: ufs: core: Fix out-of-bounds warnings in ufshcd_exec_raw_upiu_cmd()
Fix the following out-of-bounds warnings by enclosing some structure

Refactor the code by making it more structured.

The problem is that the original code is trying to copy data into a bunch
of struct members adjacent to each other in a single call to memcpy(). Now
that a new struct _upiu_req_ enclosing all those adjacent members is
introduced, memcpy() doesn't overrun the length of &treq.req_header,
because the address of the new struct object _upiu_req_ is used as the
destination, instead. The same problem is present when memcpy() overruns
the length of the source &treq.rsp_header; in this case the address of the
new struct object _upiu_rsp_ is used, instead.

Also, this helps with the ongoing efforts to enable -Warray-bounds and
avoid confusing the compiler.

Update enclosure identifier field corresponding to physical devices in

During device add the SCSI devtype is filled in during slave_configure().
However, when pqi_scsi_update_device() runs (REGNEWD) the firmware returns
zero for the SCSI devtype field, and valid devtype is overwritten by
zero. Due to this, lsscsi output shows wrong values.

c7ffedb3a7 scsi: smartpqi: Add stream detection
Enhance performance by adding sequential stream detection for RAID5/RAID6
sequential write requests. Reduce stripe lock contention with full-stripe
write operations.

There is one common stripe lock for each RAID volume that can be set by
either the RAID engine or the AIO engine. The AIO path has I/O request
sizes well below the stripe size resulting in many Read-Modify-Write
operations.

Sending the request to the RAID engine allows for coalescing requests into
full stripe operations resulting in reduced Read-Modify-Write operations.

In this case, the code is entirely valid, as the string is properly

case it exceeds a page.

This cannot really happen here, so just simplify it to a sizeof().

02ec144292 scsi: hpsa: Fix boot on ia64 (atomic_t alignment)
Boot failure was observed on an HP rx3600 ia64 machine with RAID bus
controller: Hewlett-Packard Company Smart Array P600:

    kernel unaligned access to 0xe000000105dd8b95, ip=0xa000000100b87551
    kernel unaligned access to 0xe000000105dd8e95, ip=0xa000000100b87551
    hpsa 0000:14:01.0: Controller reports max supported commands of 0 Using 16 instead. Ensure that firmware is up to date.
    swapper/0[1]: error during unaligned kernel access

The unaligned access comes from 'struct CommandList' that happens to be
packed. Commit f749d8b7a9 ("scsi: hpsa: Correct dev cmds outstanding for
retried cmds") introduced unexpected padding and unaligned atomic_t from
natural alignment to something else.

This change removes packing annotation from a struct not intended to be
sent to controller as is. This restores natural `atomic_t` alignment.

The change was tested on the same rx3600 machine.

5482a9a1a8 scsi: hpsa: Use __packed on individual structs, not header-wide
The hpsa driver uses data structures which contain a combination of driver
internals and commands sent directly to the hardware. To manage alignment
for the hardware portions the driver used #pragma pack(1).

Commit f749d8b7a9 ("scsi: hpsa: Correct dev cmds outstanding for retried
cmds") switched an existing variable from int to bool. Due to the pragma an
atomic_t in the same data structure ended up being misaligned and broke
boot on ia64.

Add __packed to every struct and union in the header file. Subsequent
commits will address the actual atomic_t misalignment regression.

The commit is a no-op at least on ia64:
    $ diff -u <(objdump -d -r old.o) <(objdump -d -r new.o)

d2478dd256 scsi: fnic: Remove bogus ratelimit messages
Commit b43abcbbd5 ("scsi: fnic: Ratelimit printks to avoid flooding when
vlan is not set by the switch.i") added printk_ratelimit() in front of a
couple of debug-mode messages to reduce logging overrun when debugging the
driver. The code:

>           if (printk_ratelimit())
>                   FNIC_FCS_DBG(KERN_DEBUG, fnic->lport->host,
>                             "Start VLAN Discovery\n");

ends up calling printk_ratelimit() quite often, triggering many kernel
messages about callbacks being supressed.

The fix is to decompose FNIC_FCS_DBG(), then change the order of checks so
that printk_ratelimit() is only called if driver debugging is enabled.

9e67600ed6 scsi: iscsi: Fix race condition between login and sync thread
A kernel panic was observed due to a timing issue between the sync thread
and the initiator processing a login response from the target. The session
reopen can be invoked both from the session sync thread when iscsid
restarts and from iscsid through the error handler. Before the initiator
receives the response to a login, another reopen request can be sent from
the error handler/sync session. When the initial login response is
subsequently processed, the connection has been closed and the socket has
been released.

To fix this a new connection state, ISCSI_CONN_BOUND, is added:

 - Set the connection state value to ISCSI_CONN_DOWN upon
   iscsi_if_ep_disconnect() and iscsi_if_stop_conn()

 - Set the connection state to the newly created value ISCSI_CONN_BOUND
   after bind connection (transport->bind_conn())

 - In iscsi_set_param(), return -ENOTCONN if the connection state is not
   either ISCSI_CONN_BOUND or ISCSI_CONN_UP

On some configurations, gcc warns about overlapping source and destination
arguments to snprintf:

drivers/scsi/pm8001/pm8001_init.c:977:3: error: 'snprintf' argument 4 may overlap destination object 'pm8001_ha' [-Werror=restrict]
  977 |   snprintf(drvname, len, "%s-%d", pm8001_ha->name, i);
      |   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/scsi/pm8001/pm8001_init.c:962:56: note: destination object referenced by 'restrict'-qualified argument 1 was declared here
  962 | static u32 pm8001_request_msix(struct pm8001_hba_info *pm8001_ha)
      |                                ~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~

I first assumed this was a gcc bug, as that should not happen, but a
reduced test case makes it clear that this happens when the loop counter is
not bounded by the array size.

Help the compiler out by adding an explicit limit here to make the code
slightly more robust and avoid the warning.

adb253433d scsi: bnx2i: Make bnx2i_process_iscsi_error() simpler and more robust
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.

39c0c8553b scsi: Revert "qla2xxx: Make sure that aborted commands are freed"
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.

62fc266148 scsi: ibmvfc: Make ibmvfc_wait_for_ops() MQ aware
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.

8b1c9b2025 scsi: ibmvfc: Fix potential race in ibmvfc_wait_for_ops()
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.

3d9c3dcc58 scsi: storvsc: Enable scatterlist entry lengths > 4Kbytes
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).

Don't use spin_lock_bh() to protect the update of the write pointer offset
cache, but use spin_lock_irqsave() for it.

In st_open(), if STp->in_use is true, STp will be freed by
scsi_tape_put(). However, STp is still used by DEBC_printk() after. It is
better to DEBC_printk() before scsi_tape_put().

febb0cc847 scsi: ibmvfc: Free channel_setup_buf during device tear down
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().
