commit 1abc900ddda8ad2ef739fedf498d415655b6c3b8 upstream.
Some firmware versions of the 9600 series SAS HBA byte-swap the REPORT
ZONES command reply buffer from ATA-ZAC devices by directly accessing the
buffer in the host memory. This does not respect the default command DMA
direction and causes IOMMU page faults on architectures with an IOMMU
enforcing write-only mappings for DMA_FROM_DEVICE DMA direction (e.g. AMD
hosts), leading to the device capacity to be dropped to 0:

using DMA_BIDIRECTIONAL, that is, using a read-write IOMMU mapping.

Avoid such issue by always mapping the buffer of REPORT ZONES commands

introducing the helper function _base_scsi_dma_map() and using this helper

commit 9f499b8c791d2983c0a31a543c51d1b2f15e8755 upstream.
While working on simplifying the minmax functions, and avoiding
excessive macro expansion, it turns out that the sr.c use of the
'clamp()' macro has the arguments the wrong way around.
The clamp logic is
val = clamp(in, low, high);
and it returns the input clamped to the low/high limits. But sr.c ddid
speed = clamp(0, speed, 0xffff / 177);
which clamps the value '0' to the range '[speed, 0xffff / 177]' and ends
up being nonsensical.
Happily, I don't think anybody ever cared.

This makes it hard to read. This patch convert those opcode and flags into

commit c3d98b12eef8db436e32f1a8c5478be57dc15621 upstream.
The device does not come online when the target port is online. There were
multiple RSCNs indicating multiple devices were affected. Driver is in the
process of finishing a fabric scan. A new RSCN (device up) arrived at the
tail end of the last fabric scan. Driver mistakenly thinks the new RSCN is
being taken care of by the previous fabric scan, where this notification is
cleared and not acted on. The laser needs to be blinked again to get the
device to show up.
To prevent driver from accidentally clearing the RSCN notification, each
RSCN is given a generation value. A fabric scan will scan for that
generation(s). Any new RSCN arrive after the scan start will have a new
generation value. This will trigger another scan to get latest data. The
RSCN notification flag will be cleared when the scan is associate to that
generation.

Certain vendor specific targets initially register with the fabric as an
initiator function first and then re-register as a target function
afterwards.
The timing of the target function re-registration can cause a race
condition such that the driver is stuck assuming the remote port as an
initiator function and never discovers the target's hosted LUNs.
Expand the nlp_state qualifier to also include NLP_STE_PRLI_ISSUE because
the state means that PRLI was issued but we have not quite reached
MAPPED_NODE state yet. If we received an RSCN in the PRLI_ISSUE state,
then we should restart discovery again by going into DEVICE_RECOVERY.

In lpfc_prep_embed_io, the memcpy(ptr, fcp_cmnd, sgl->sge_len) is
referencing a little endian formatted sgl->sge_len value. So, the memcpy
can cause big endian systems to crash.

The SCSI disk message "Starting disk" to signal resuming of a suspended
disk is printed in both sd_resume() and sd_resume_common() which results
in this message being printed twice when resuming from e.g. autosuspend:

[ 4980.558806] sd 0:0:0:0: [sda] Starting disk
Fix this double print by removing the call to sd_printk() from sd_resume()
and moving the call to sd_printk() in sd_resume_common() earlier in the
function, before the check using sd_do_start_stop(). Doing so, the message
is printed once regardless if sd_resume_common() actually executes
sd_start_stop_device() (i.e. SCSI device case) or not (libsas and libata
managed ATA devices case).

Target debugfs entry is removed via async_schedule() which isn't drained

Fix it by switching to domain async schedule, and draining it before

The function mpi3mr_qcmd() of the mpi3mr driver is able to indicate to
the HBA if a read or write command directed at an ATA device should be
translated to an NCQ read/write command with the high prioiryt bit set
when the request uses the RT priority class and the user has enabled NCQ
priority through sysfs.
However, unlike the mpt3sas driver, the mpi3mr driver does not define
the sas_ncq_prio_supported and sas_ncq_prio_enable sysfs attributes, so
the ncq_prio_enable field of struct mpi3mr_sdev_priv_data is never
actually set and NCQ Priority cannot ever be used.
Fix this by defining these missing atributes to allow a user to check if
an ATA device supports NCQ priority and to enable/disable the use of NCQ
priority. To do this, lift the function scsih_ncq_prio_supp() out of the
mpt3sas driver and make it the generic SCSI SAS transport function
sas_ata_ncq_prio_supported(). Nothing in that function is hardware
specific, so this function can be used in both the mpt3sas driver and
the mpi3mr driver.

For SCSI devices supporting the Command Duration Limits feature set, the
user can enable/disable this feature use through the sysfs device attribute
"cdl_enable". This attribute modification triggers a call to
scsi_cdl_enable() to enable and disable the feature for ATA devices and set
the scsi device cdl_enable field to the user provided bool value. For SCSI
devices supporting CDL, the feature set is always enabled and
scsi_cdl_enable() is reduced to setting the cdl_enable field.
However, for ATA devices, a drive may spin-up with the CDL feature enabled
by default. But the SCSI device cdl_enable field is always initialized to
false (CDL disabled), regardless of the actual device CDL feature
state. For ATA devices managed by libata (or libsas), libata-core always
disables the CDL feature set when the device is attached, thus syncing the
state of the CDL feature on the device and of the SCSI device cdl_enable
field. However, for ATA devices connected to a SAS HBA, the CDL feature is
not disabled on scan for ATA devices that have this feature enabled by
default, leading to an inconsistent state of the feature on the device with
the SCSI device cdl_enable field.
Avoid this inconsistency by adding a call to scsi_cdl_enable() in
scsi_cdl_check() to make sure that the device-side state of the CDL feature
set always matches the scsi device cdl_enable field state. This implies
that CDL will always be disabled for ATA devices connected to SAS HBAs,
which is consistent with libata/libsas initialization of the device.

Commit 321da3dc1f3c ("scsi: sd: usb_storage: uas: Access media prior
to querying device properties") triggered a read to LBA 0 before
attempting to inquire about device characteristics. This was done
because some protocol bridge devices will return generic values until
an attached storage device's media has been accessed.
Pierre Tomon reported that this change caused problems on a large
capacity external drive connected via a bridge device. The bridge in
question does not appear to implement the READ(10) command.
Issue a READ(16) instead of READ(10) when a device has been identified
as preferring 16-byte commands (use_16_for_rw heuristic).

The prior strscpy() replacement of strncpy() here expected the
manufacture_reply strings to be NUL-terminated, but it is possible
they are not, as the code pattern here shows, e.g., edev->vendor_id
being exactly 1 character larger than manufacture_reply->vendor_id,
and the replaced strncpy() was copying only up to the size of the
source character array. Replace this with memtostr(), which is the
unambiguous way to convert a maybe not-NUL-terminated character array
into a NUL-terminated string.

updating to 6.8.4. Peter bisected the issue and identified commit
b5fc07a5fb56 ("scsi: core: Consult supported VPD page list prior to

Turns out the enclosure device in Peter's system reports a byteswapped
page length for VPD page 0. It reports "02 00" as page length instead
of "00 02". This causes us to attempt to access 516 bytes (page length
+ header) of information despite only 2 pages being present.
Limit the page search scope to the size of our VPD buffer to guard
against devices returning a larger page count than requested.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Skip E820 checks for MCFG ECAM regions for new (2016+) machines,
since there's no requirement to describe them in E820 and some
platforms require ECAM to work (Bjorn Helgaas)
- Rename PCI_IRQ_LEGACY to PCI_IRQ_INTX to be more specific (Damien
Le Moal)
- Remove last user and pci_enable_device_io() (Heiner Kallweit)
- Wait for Link Training==0 to avoid possible race (Ilpo Järvinen)
- Skip waiting for devices that have been disconnected while
suspended (Ilpo Järvinen)
- Clear Secondary Status errors after enumeration since Master Aborts
and Unsupported Request errors are an expected part of enumeration
(Vidya Sagar)
MSI:
- Remove unused IMS (Interrupt Message Store) support (Bjorn Helgaas)
Error handling:
- Mask Genesys GL975x SD host controller Replay Timer Timeout
correctable errors caused by a hardware defect; the errors cause
interrupts that prevent system suspend (Kai-Heng Feng)
- Fix EDR-related _DSM support, which previously evaluated revision 5
but assumed revision 6 behavior (Kuppuswamy Sathyanarayanan)
ASPM:
- Simplify link state definitions and mask calculation (Ilpo
Järvinen)
Power management:
- Avoid D3cold for HP Pavilion 17 PC/1972 PCIe Ports, where BIOS
apparently doesn't know how to put them back in D0 (Mario
Limonciello)
CXL:
- Support resetting CXL devices; special handling required because
CXL Ports mask Secondary Bus Reset by default (Dave Jiang)
DOE:
- Support DOE Discovery Version 2 (Alexey Kardashevskiy)
Endpoint framework:
- Set endpoint BAR to be 64-bit if the driver says that's all the
device supports, in addition to doing so if the size is >2GB
(Niklas Cassel)
- Simplify endpoint BAR allocation and setting interfaces (Niklas
Cassel)
Cadence PCIe controller driver:
- Drop DT binding redundant msi-parent and pci-bus.yaml (Krzysztof
Kozlowski)
Cadence PCIe endpoint driver:
- Configure endpoint BARs to be 64-bit based on the BAR type, not the
BAR value (Niklas Cassel)
Freescale Layerscape PCIe controller driver:
- Convert DT binding to YAML (Frank Li)
MediaTek MT7621 PCIe controller driver:
- Add DT binding missing 'reg' property for child Root Ports
(Krzysztof Kozlowski)
- Fix theoretical string truncation in PHY name (Sergio Paracuellos)
NVIDIA Tegra194 PCIe controller driver:
- Return success for endpoint probe instead of falling through to the
failure path (Vidya Sagar)
Renesas R-Car PCIe controller driver:
- Add DT binding missing IOMMU properties (Geert Uytterhoeven)
- Add DT binding R-Car V4H compatible for host and endpoint mode
(Yoshihiro Shimoda)
Rockchip PCIe controller driver:

BAR value (Niklas Cassel)
- Add DT binding missing maxItems to ep-gpios (Krzysztof Kozlowski)
- Set the Subsystem Vendor ID, which was previously zero because it
was masked incorrectly (Rick Wertenbroek)
Synopsys DesignWare PCIe controller driver:
- Restructure DBI register access to accommodate devices where this
requires Refclk to be active (Manivannan Sadhasivam)
- Remove the deinit() callback, which was only need by the
pcie-rcar-gen4, and do it directly in that driver (Manivannan
Sadhasivam)
- Add dw_pcie_ep_cleanup() so drivers that support PERST# can clean
up things like eDMA (Manivannan Sadhasivam)
- Rename dw_pcie_ep_exit() to dw_pcie_ep_deinit() to make it parallel
to dw_pcie_ep_init() (Manivannan Sadhasivam)
- Rename dw_pcie_ep_init_complete() to dw_pcie_ep_init_registers() to
reflect the actual functionality (Manivannan Sadhasivam)
- Call dw_pcie_ep_init_registers() directly from all the glue
drivers, not just those that require active Refclk from the host
(Manivannan Sadhasivam)
- Remove the "core_init_notifier" flag, which was an obscure way for
glue drivers to indicate that they depend on Refclk from the host
(Manivannan Sadhasivam)
TI J721E PCIe driver:
- Add DT binding J784S4 SoC Device ID (Siddharth Vadapalli)
- Add DT binding J722S SoC support (Siddharth Vadapalli)
TI Keystone PCIe controller driver:
- Add DT binding missing num-viewport, phys and phy-name properties
(Jan Kiszka)
Miscellaneous:
- Constify and annotate with __ro_after_init (Heiner Kallweit)
- Convert DT bindings to YAML (Krzysztof Kozlowski)
- Check for kcalloc() failure in of_pci_prop_intr_map() (Duoming
Zhou)"
