We find that some disks use D2H frame instead of SDB frame to return NCQ
error. Currently, only the I/O corresponding to the D2H frame is processed
in this scenario, which does not meet the processing requirements of the
NCQ error scenario. So we set dev_status to HISI_SAS_DEV_NCQ_ERR and abort
all I/Os of the disk in this scenario.

Hello,
this series fixes the same issue in four drivers. The warning is a false
positive and to suppress it the driver structs are marked with
__refdata and a comment is added to describe the (non-trivial)
situation.

Modules registering driver with scsi_driver_register() might forget to set
.owner field. The field is used by some of other kernel parts for
reference counting (try_module_get()), so it is expected that drivers will
set it.
Solve the problem by moving this task away from the drivers to the core
scsi code, just like we did for platform_driver in commit 9447057eaff8
("platform_device: use a macro instead of platform_driver_register").

Commit 27f58c04a8f4 ("scsi: sg: Avoid sg device teardown race") introduced
an incorrect WARN_ON_ONCE() and missed a sequence where sg_device_destroy()
was used after scsi_device_put().
sg_device_destroy() is accessing the parent scsi_device request_queue which
will already be set to NULL when the preceding call to scsi_device_put()
removed the last reference to the parent scsi_device.
Drop the incorrect WARN_ON_ONCE() - allowing more than one concurrent
access to the sg device - and make sure sg_device_destroy() is not used
after scsi_device_put() in the error handling.

This series [1] reduced the kmalloc() minimum alignment on arm64 to 8 bytes
(from 128). In libsas, this will cause SMP requests to be 8-byte aligned
through kmalloc() allocation. However, for hisi_sas hardware, all command
addresses must be 16-byte-aligned. Otherwise, the commands fail to be
executed.
ARCH_DMA_MINALIGN represents the minimum (static) alignment for safe DMA
operations, so use ARCH_DMA_MINALIGN as the alignment for SMP request.

The myrb and myrs drivers use an odd way of implementing their sysfs files,
calling snprintf() with a fixed length of 32 bytes to print into a page
sized buffer. One of the strings is actually longer than 32 bytes, which
clang can warn about:
drivers/scsi/myrb.c:1906:10: error: 'snprintf' will always be truncated; specified size is 32, but format string expands to at least 34 [-Werror,-Wformat-truncation]
drivers/scsi/myrs.c:1089:10: error: 'snprintf' will always be truncated; specified size is 32, but format string expands to at least 34 [-Werror,-Wformat-truncation]
These could all be plain sprintf() without a length as the buffer is always
long enough. On the other hand, sysfs files should not be overly long
either, so just double the length to make sure the longest strings don't
get truncated here.

Commit b4d3ddd2df75 ("scsi: libsas: Define NCQ Priority sysfs attributes
for SATA devices") introduced support for ATA NCQ priority control for ATA
devices managed by libsas. This commit introduces the ncq_prio_supported
and ncq_prio_enable sysfs device attributes to discover and control the use
of this features, similarly to libata. However, libata publicly declares
these device attributes and export them for use in ATA low level
drivers. This leads to a compilation error when libsas and libata are
built-in due to the double definition:
ld: drivers/ata/libata-sata.o:/home/Linux/scsi/drivers/ata/libata-sata.c:900:
multiple definition of `dev_attr_ncq_prio_supported';
drivers/scsi/libsas/sas_ata.o:/home/Linux/scsi/drivers/scsi/libsas/sas_ata.c:984:

Resolve this problem by directly declaring the libsas attributes instead of
using the DEVICE_ATTR() macro. And for good measure, the device attribute
variables are also renamed.

Commit fc663711b944 ("scsi: core: Remove the /proc/scsi/${proc_name}
directory earlier") fixed a bug related to modules loading/unloading, by
adding a call to scsi_proc_hostdir_rm() on scsi_remove_host(). But that led
to a potential duplicate call to the hostdir_rm() routine, since it's also
called from scsi_host_dev_release(). That triggered a regression report,
which was then fixed by commit be03df3d4bfe ("scsi: core: Fix a procfs host
directory removal regression"). The fix just dropped the hostdir_rm() call
from dev_release().
But it happens that this proc directory is created on scsi_host_alloc(),
and that function "pairs" with scsi_host_dev_release(), while
scsi_remove_host() pairs with scsi_add_host(). In other words, it seems the
reason for removing the proc directory on dev_release() was meant to cover
cases in which a SCSI host structure was allocated, but the call to
scsi_add_host() didn't happen. And that pattern happens to exist in some
error paths, for example.
Syzkaller causes that by using USB raw gadget device, error'ing on
usb-storage driver, at usb_stor_probe2(). By checking that path, we can see
that the BadDevice label leads to a scsi_host_put() after a SCSI host
allocation, but there's no call to scsi_add_host() in such path. That leads
to messages like this in dmesg (and a leak of the SCSI host proc
structure):
usb-storage 4-1:87.51: USB Mass Storage device detected
proc_dir_entry 'scsi/usb-storage' already registered
WARNING: CPU: 1 PID: 3519 at fs/proc/generic.c:377 proc_register+0x347/0x4e0 fs/proc/generic.c:376
The proper fix seems to still call scsi_proc_hostdir_rm() on dev_release(),
but guard that with the state check for SHOST_CREATED; there is even a
comment in scsi_host_dev_release() detailing that: such conditional is
meant for cases where the SCSI host was allocated but there was no calls to
{add,remove}_host(), like the usb-storage case.
This is what we propose here and with that, the error path of usb-storage
does not trigger the warning anymore.

libata sysfs attributes cannot be used for libsas-managed SATA devices
because the ata_port location is different for libsas.
Defined sysfs attributes (visible for SATA devices only):
- /sys/block/sda/device/ncq_prio_enable
- /sys/block/sda/device/ncq_prio_supported
The newly defined attributes will pass the correct ata_port to libata
helper functions.

When the "storcli2 show" command is executed for eHBA-9600, mpi3mr driver
prints this WARNING message:
memcpy: detected field-spanning write (size 128) of single field "bsg_reply_buf->reply_buf" at drivers/scsi/mpi3mr/mpi3mr_app.c:1658 (size 1)
WARNING: CPU: 0 PID: 12760 at drivers/scsi/mpi3mr/mpi3mr_app.c:1658 mpi3mr_bsg_request+0x6b12/0x7f10 [mpi3mr]
The cause of the WARN is 128 bytes memcpy to the 1 byte size array "__u8
replay_buf[1]" in the struct mpi3mr_bsg_in_reply_buf. The array is intended
to be a flexible length array, so the WARN is a false positive.
To suppress the WARN, remove the constant number '1' from the array
declaration and clarify that it has flexible length. Also, adjust the
memory allocation size to match the change.

Commit 3cc2ffe5c16d ("scsi: sd: Differentiate system and runtime start/stop
management") introduced the manage_system_start_stop scsi_device flag to
allow libata to indicate to the SCSI disk driver that nothing should be
done when resuming a disk on system resume. This change turned the
execution of sd_resume() into a no-op for ATA devices on system
resume. While this solved deadlock issues during device resume, this change
also wrongly removed the execution of opal_unlock_from_suspend(). As a
result, devices with TCG OPAL locking enabled remain locked and
inaccessible after a system resume from sleep.
To fix this issue, introduce the SCSI driver resume method and implement it
with the sd_resume() function calling opal_unlock_from_suspend(). The
former sd_resume() function is renamed to sd_resume_common() and modified
to call the new sd_resume() function. For non-ATA devices, this result in
no functional changes.
In order for libata to explicitly execute sd_resume() when a device is
resumed during system restart, the function scsi_resume_device() is
introduced. libata calls this function from the revalidation work executed
on devie resume, a state that is indicated with the new device flag
ATA_DFLAG_RESUMING. Doing so, locked TCG OPAL enabled devices are unlocked
on resume, allowing normal operation.

sg_remove_sfp_usercontext() must not use sg_device_destroy() after calling
scsi_device_put().
sg_device_destroy() is accessing the parent scsi_device request_queue which
will already be set to NULL when the preceding call to scsi_device_put()
removed the last reference to the parent scsi_device.
The resulting NULL pointer exception will then crash the kernel.

Justin Stitt <[email protected]> says:
This series contains multiple replacements of strncpy throughout the
scsi subsystem.
strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces. The details of each replacement will be in their
respective patch.

Pull more SCSI updates from James Bottomley:
"The vfs has long had a write lifetime hint mechanism that gives the
expected longevity on storage of the data being written. f2fs was the
original consumer of this and used the hint for flash data placement
(mostly to avoid write amplification by placing objects with similar
lifetimes in the same erase block).
More recently the SCSI based UFS (Universal Flash Storage) drivers
have wanted to take advantage of this as well, for the same reasons as
f2fs, necessitating plumbing the write hints through the block layer
and then adding it to the SCSI core.
The vfs write_hints already taken plumbs this as far as block and this
completes the SCSI core enabling based on a recently agreed reuse of
the old write command group number. The additions to the scsi_debug
driver are for emulating this property so we can run tests on it in
the absence of an actual UFS device"
