scsi: sd_zbc: block: Respect bio vector limits for REPORT ZONES buffer
The REPORT ZONES buffer size is currently limited by the HBA's maximum
segment count to ensure the buffer can be mapped. However, the block
layer further limits the number of iovec entries to 1024 when allocating
a bio.
To avoid allocation of buffers too large to be mapped, further restrict
the maximum buffer size to BIO_MAX_INLINE_VECS.
Replace the UIO_MAXIOV symbolic name with the more contextually
appropriate BIO_MAX_INLINE_VECS.

scsi: scsi_debug: Reduce DEF_ATOMIC_WR_MAX_LENGTH
The default atomic write max length in DEF_ATOMIC_WR_MAX_LENGTH is
excessively large.
For 512B LBS, we would get a 4MB max, but due to block layer atomic write
restrictions this is limited to 512KB.
Reduce DEF_ATOMIC_WR_MAX_LENGTH to a value which would be more realistic
(for a real device supporting atomic writes), 64KB.

scsi: lpfc: Notify FC transport of rport disappearance during PCI fcn reset
A PCI function reset implies a temporary disappearance of a fc_rport.
So, call lpfc_scsi_dev_block(), which sets all mapped fc_rports into the
temporary FC_PORTSTATE_BLOCKED state. Once PCI function reset completes
and link reinitialized, the fc_rport is rediscovered and
FC_PORTSTATE_BLOCKED state is removed.

scsi: lpfc: Fix lpfc_check_sli_ndlp() handling for GEN_REQUEST64 commands
In lpfc_check_sli_ndlp(), the get_job_els_rsp64_did remote_id assignment
does not apply for GEN_REQUEST64 commands as it only has meaning for a
ELS_REQUEST64 command. So, if (iocb->ndlp == ndlp) is false, we could
erroneously return the wrong value. Fix by replacing the fallthrough
statement with a break statement before the remote_id check.

scsi: qla4xxx: Remove duplicate struct crb_addr_pair
In preparation for making the kmalloc family of allocators type aware, we
need to make sure that the returned type from the allocation matches the
type of the variable being assigned. (Before, the allocator would always
return "void *", which can be implicitly cast to any pointer type.)
The assigned type is "struct crb_addr_pair *" and the returned type will
be a _different_ "struct crb_addr_pair *", causing a warning. This really
stumped me for a bit. :) Drop the redundant declaration.

SATA devices are lost when FLR is performed while the controller and disks

This is because the libata layer is called to initialize the SATA device

command fails. As a result, the revalidate fails, and the SATA device is

scsi: hisi_sas: Call I_T_nexus after soft reset for SATA disk
In commit 21c7e972475e ("scsi: hisi_sas: Disable SATA disk phy for severe
I_T nexus reset failure"), if the softreset fails upon certain
conditions, the PHY connected to the disk is disabled directly. Manual
recovery is required, which is inconvenient for users in actual use.
In addition, SATA disks do not support simultaneous connection of multiple
hosts. Therefore, when multiple controllers are connected to a SATA disk
at the same time, the controller which is connected later failed to issue
an ATA softreset to the SATA disk. As a result, the PHY associated with
the disk is disabled and cannot be automatically recovered.
Now that, we will not focus on the execution result of softreset. No
matter whether the execution is successful or not, we will directly carry
out I_T_nexus_reset.

Commands that have not been completed with scsi_done() do not clear the

scsi: ufs: mcq: Add NULL check in ufshcd_mcq_abort()
A race can occur between the MCQ completion path and the abort handler:
once a request completes, __blk_mq_free_request() sets rq->mq_hctx to
NULL, meaning the subsequent ufshcd_mcq_req_to_hwq() call in
ufshcd_mcq_abort() can return a NULL pointer. If this NULL pointer is
dereferenced, the kernel will crash.
Add a NULL check for the returned hwq pointer. If hwq is NULL, log an
error and return FAILED, preventing a potential NULL-pointer
dereference. As suggested by Bart, the ufshcd_cmd_inflight() check is
removed.
This is similar to the fix in commit 74736103fb41 ("scsi: ufs: core: Fix

scsi: elx: sli4: Replace deprecated strncpy() with strscpy()
strncpy() is deprecated for NUL-terminated destination buffers; use
strscpy() instead.
Since sli_config_cmd_init() already zeroes out the destination buffers,
the potential NUL-padding by strncpy() is unnecessary. strscpy() copies
only the required characters and guarantees NUL-termination.
And since all three destination buffers have a fixed length, strscpy()
automatically determines their size using sizeof() when the argument is
omitted. This makes any explicit sizeof() calls unnecessary.
The source strings are also NUL-terminated and meet the __must_be_cstr()
requirement of strscpy().
No functional changes intended.

scsi: ufs: core: Delegate the interrupt service routine to a threaded IRQ handler
On systems with a large number request slots and unavailable MCQ ESI,
the current design of the interrupt handler can delay handling of other
subsystems interrupts causing display artifacts, GPU stalls or system
firmware requests timeouts.
Since the interrupt routine can take quite some time, it's preferable to
move it to a threaded handler and leave the hard interrupt handler wake
up the threaded interrupt routine, the interrupt line would be masked
until the processing is finished in the thread thanks to the
IRQS_ONESHOT flag.
When MCQ & ESI interrupts are enabled the I/O completions are now
directly handled in the "hard" interrupt routine to keep IOPs high since
queues handling is done in separate per-queue interrupt routines.
This fixes all encountered issued when running FIO tests on the Qualcomm
SM8650 platform.

scsi: soc: qcom: ice: Add HWKM support to the ICE driver
Qualcomm's Inline Crypto Engine (ICE) version 3.2 and later includes a
key management hardware block called the Hardware Key Manager (HWKM).
Add support for HWKM to the ICE driver. HWKM provides hardware-wrapped
key support where the ICE (storage) keys are not exposed to software and
instead are protected in hardware. Later patches will wire up this
feature to ufs-qcom and sdhci-msm using the support added in this patch.
HWKM and legacy mode are currently mutually exclusive. The selection of
which mode to use has to be made before the storage driver(s) registers
any inline encryption capable disk(s) with the block layer (i.e.,
generally at boot time) so that the appropriate crypto capabilities can
be advertised to upper layers. Therefore, make the ICE driver select
HWKM mode when the all of the following are true:
- The new module parameter qcom_ice.use_wrapped_keys=1 is specified.
- HWKM is present and is at least v2, i.e. ICE is v3.2.1 or later.
- The SCM calls needed to fully use HWKM are supported by TrustZone.
[EB: merged related patches; fixed the module parameter to work
correctly; dropped unnecessary support for HWKM v1; fixed error
handling; improved log messages, comments, and commit message;
fixed naming; merged enable and init functions; and other cleanups]

scsi: soc: qcom: ice: Make qcom_ice_program_key() take struct blk_crypto_key
qcom_ice_program_key() currently accepts the key as an array of bytes,
algorithm ID, key size enum, and data unit size. However both callers
have a struct blk_crypto_key which contains all that information. Thus
they both have similar code that converts the blk_crypto_key into the
form that qcom_ice_program_key() wants. Once wrapped key support is
added, the key type would need to be added to the arguments too.
Therefore, this patch changes qcom_ice_program_key() to take in all this
information as a struct blk_crypto_key directly. The calling code is
updated accordingly. This ends up being much simpler, and it makes the
key type be passed down automatically once wrapped key support is added.
Based on a patch by Gaurav Kashyap <quic_gaurkash@quicinc.com> that
replaced the byte array argument only. This patch makes the
blk_crypto_key replace other arguments like the algorithm ID too,
ensuring that there remains only one source of truth.

scsi: megaraid_sas: Block zero-length ATA VPD inquiry
A firmware bug was observed where ATA VPD inquiry commands with a
zero-length data payload were not handled and failed with a non-standard
status code of 0xf0.
Avoid sending ATA VPD inquiry commands without data payload by setting
the device no_vpd_size flag to 1. In addition, if the firmware returns a
status code of 0xf0, set scsi_cmnd->result to CHECK_CONDITION to
facilitate proper error handling.

scsi: ufs: core: Add device level exception support
The ufs device JEDEC specification version 4.1 adds support for the
device level exception events. To support this new device level
exception feature, expose two new sysfs nodes below to provide the user
space access to the device level exception information.
/sys/bus/platform/drivers/ufshcd/*/device_lvl_exception_count
/sys/bus/platform/drivers/ufshcd/*/device_lvl_exception_id
The device_lvl_exception_count sysfs node reports the number of device
level exceptions that have occurred since the last time this variable is
reset. Writing a value of 0 will reset it. The device_lvl_exception_id
reports the exception ID which is the qDeviceLevelExceptionID attribute
of the device JEDEC specifications version 4.1 and later. The user space
application can query these sysfs nodes to get more information about
the device level exception.

scsi: smartpqi: Use is_kdump_kernel() to check for kdump
The smartpqi driver checks the reset_devices variable to determine
whether special adjustments need to be made for kdump. This has the
effect that after a regular kexec reboot, some driver parameters such as
max_transfer_size are much lower than usual. More importantly, kexec
reboot tests have revealed memory corruption caused by the driver log
being written to system memory after a kexec.
Fix this by testing is_kdump_kernel() rather than reset_devices where
appropriate.
