The virt_boundary_mask limit requires an unlimited max_segment_size for
bio splitting to not corrupt data. Historically, the block layer tried
to validate this, although the check was half-hearted until the addition
of the atomic queue limits API. The full blown check then triggered
issues with stacked devices incorrectly inheriting limits such as the
virt boundary and got disabled in commit b561ea56a2 ("block: allow
device to have both virt_boundary_mask and max segment size") instead of
fixing the issue properly.
Ensure that the SCSI mid layer doesn't set the default low
max_segment_size limit for this case, and check for invalid
max_segment_size values in the host template, similar to the original
block layer check given that SCSI devices can't be stacked.
This fixes reported data corruption on storvsc, although as far as I can
tell storvsc always failed to properly set the max_segment_size limit as
the SCSI APIs historically applied that when setting up the host, while
storvsc only set the virt_boundary_mask when configuring the scsi_device.

sd_read_block_limits_ext() currently assumes that vpd->len excludes the
size of the page header. However, vpd->len describes the size of the entire
VPD page, therefore the sanity check is incorrect.
In practice this is not really a problem since we don't attach VPD
pages unless they actually report data trailing the header. But fix
the length check regardless.
This issue was identified by Wukong-Agent (formerly Tencent Woodpecker), a
code security AI agent, through static code analysis.

When both the RHBA and RPA FDMI requests time out, fnic reuses a frame to
send ABTS for each of them. On send completion, this causes an attempt to
free the same frame twice that leads to a crash.
Fix crash by allocating separate frames for RHBA and RPA, and modify ABTS
logic accordingly.
Tested by checking MDS for FDMI information.
Tested by using instrumented driver to:
- Drop PLOGI response
- Drop RHBA response
- Drop RPA response
- Drop RHBA and RPA response
- Drop PLOGI response + ABTS response
- Drop RHBA response + ABTS response
- Drop RPA response + ABTS response

When a host is configured with a few LUNs and I/O is running, injecting
FC faults repeatedly leads to path recovery problems. The LUNs have 4
paths each and 3 of them come back active after say an FC fault which
makes 2 of the paths go down, instead of all 4. This happens after
several iterations of continuous FC faults.
Reason here is that we're returning an I/O error whenever we're
encountering sense code 06/04/0a (LOGICAL UNIT NOT ACCESSIBLE, ASYMMETRIC
ACCESS STATE TRANSITION) instead of retrying.

Currently storvsc_timeout is only used in storvsc_sdev_configure(), and
5s and 10s are used elsewhere. It turns out that rarely the 5s is not
enough on Azure, so let's use storvsc_timeout everywhere.
In case a timeout happens and storvsc_channel_init() returns an error,
close the VMBus channel so that any host-to-guest messages in the
channel's ringbuffer, which might come late, can be safely ignored.
Add a "const" to storvsc_timeout.

Correct the error handling goto labels used when host lookup fails in
various flashnode-related event handlers:
- iscsi_new_flashnode()
- iscsi_del_flashnode()
- iscsi_login_flashnode()
- iscsi_logout_flashnode()
- iscsi_logout_flashnode_sid()
scsi_host_put() is not required when shost is NULL, so jumping to the
correct label avoids unnecessary operations. These functions previously
jumped to the wrong goto label (put_host), which did not match the
intended cleanup logic.
Use the correct exit labels (exit_new_fnode, exit_del_fnode, etc.) to
ensure proper error handling. Also remove the unused put_host label
under iscsi_new_flashnode() as it is no longer needed.
No functional changes beyond accurate error path correction.

PCIe native device hotplug:
- Ignore Presence Detect Changed caused by DPC.
pciehp already ignores Link Down/Up events caused by DPC, but on

Detect Changed event (Lukas Wunner)
- Ignore Link Down/Up caused by Secondary Bus Reset.
On hotplug ports using in-band presence detect, the reset causes a
Presence Detect Changed event, which mistakenly caused teardown and
re-enumeration of the device. Drivers may need to annotate code
that resets their device (Lukas Wunner)

pci_epc_set_msix()/pci_epc_ops::set_msix() (Niklas Cassel)
Common host controller library:

- Add T602x PCIe support (Hector Martin)
- Directly set/clear INTx mask bits because T602x dropped the
accessors that could do this without locking (Marc Zyngier)
- Move port PHY registers to their own reg items to accommodate
T602x, which moves them around; retain default offsets for existing
DTs that lack phy%d entries with the reg offsets (Hector Martin)
- Stop polling for core refclk, which doesn't work on T602x and the
bootloader has already done anyway (Hector Martin)
- Use gpiod_set_value_cansleep() when asserting PERST# in probe
because we're allowed to sleep there (Hector Martin)
Cadence PCIe controller driver:

- Apply link training workaround only on IMX6Q, IMX6SX, IMX6SP
(Richard Zhu)
- Remove redundant dw_pcie_wait_for_link() from
imx_pcie_start_link(); since the DWC core does this, imx6 only
needs it when retraining for a faster link speed (Richard Zhu)
- Toggle i.MX95 core reset to align with PHY powerup (Richard Zhu)
- Set SYS_AUX_PWR_DET to work around i.MX95 ERR051624 erratum: in
some cases, the controller can't exit 'L23 Ready' through Beacon or
PERST# deassertion (Richard Zhu)
- Clear GEN3_ZRXDC_NONCOMPL to work around i.MX95 ERR051586 erratum:
controller can't meet 2.5 GT/s ZRX-DC timing when operating at 8
GT/s, causing timeouts in L1 (Richard Zhu)
- Wait for i.MX95 PLL lock before enabling controller (Richard Zhu)
- Save/restore i.MX95 LUT for suspend/resume (Richard Zhu)

Rockchip PCIe controller driver:
- Reorder rockchip_pci_core_rsts because
reset_control_bulk_deassert() deasserts in reverse order, to fix a
link training regression (Jensen Huang)
- Mark RK3399 as being capable of raising INTx interrupts (Niklas
Cassel)
Rockchip DesignWare PCIe controller driver:
- Check only PCIE_LINKUP, not LTSSM status, to determine whether the

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.

Clang warns (or errors with CONFIG_WERROR=y):
drivers/scsi/dc395x.c:2553:6: error: variable 'id' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized]
2553 | if (!(rsel_tar_lun_id & (IDENTIFY_BASE << 8)))
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/scsi/dc395x.c:2556:22: note: uninitialized use occurs here
2556 | dcb = find_dcb(acb, id, lun);

drivers/scsi/dc395x.c:2553:2: note: remove the 'if' if its condition is always true
2553 | if (!(rsel_tar_lun_id & (IDENTIFY_BASE << 8)))
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2554 | id = rsel_tar_lun_id & 0xff;
This if statement only existed for a debugging print but it was not
removed with the debugging print in a recent cleanup, leading to id only
being initialized when the if condition is true. Remove the if statement
to ensure id is always initialized, clearing up the warning.

This is one of the last drivers depending on the block layer bounce
buffering code. Restrict it to run on non-highmem configs so that the
bounce buffering code can be removed.

scsi: ufs: core: Remove redundant query_complete trace
scsi: myrb: Fix spelling mistake "statux" -> "status"
Don Brace <don.brace@microchip.com> says:
These patches are based on Martin Petersen's 6.16/scsi-queue tree
https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git
6.16/scsi-queue
There are two main functional changes in this patch series:
smartpqi-take-drives-offline-when-controller-is-offline
smartpqi-fix-smp_processor_id-call-trace-for-preemptible-kernels
The other two patches add PCI-IDs for new controllers and change the
driver version.
This set of changes consists of:
* smartpqi-take-drives-offline-when-controller-is-offline
On rare occasions, the controller can lock up and the driver was
removing the controller instance from OS but leaving the
drives exposed and their state was still 'running'.
This patch sets the drive state as 'offline' to avoid confusion.
* smartpqi-add-new-pci_ids
Add support for more PCI devices.
* smartpqi-enhance_wwid-logging-logic
Cosmetic change for logging WWIDs for NVMe devices and for drives
that support the extended format.
* smartpqi-fix-smp_processor_id-call-trace-for-preemptible-kernels
When preemption is enabled, there are call traces in the console
logs which are annoying. The call trace mentions using
smp_processor_id(). Since the driver is only using this function call
when accessing a per_cpu variable, we changed the call to
raw_smp_processor_id(). This patch was written by
Yi Zhang <yi.zhang@redhat.com> and I am posting it on his behalf.
* smartpqi-update-driver-version-to-2.1.34-035
No functional changes.
