d14c273132 nvme-pci: disable Write Zeroes on Phison E3C/E4C
E3C/E4C SSDs do support the Write Zeroes command in theory, but have very
bad performance when using it.  As the firmware has been frozen for these
products we can not expect firmware improvements for it, so disable
Write Zeroes.

c292a337d0 nvme: Fix IOC_PR_CLEAR and IOC_PR_RELEASE ioctls for nvme devices
The IOC_PR_CLEAR and IOC_PR_RELEASE ioctls are
non-functional on NVMe devices because the nvme_pr_clear()
and nvme_pr_release() functions set the IEKEY field incorrectly.
The IEKEY field should be set only when the key is zero (i.e,
not specified).  The current code does it backwards.

Furthermore, the NVMe spec describes the persistent
reservation "clear" function as an option on the reservation
release command. The current implementation of nvme_pr_clear()
erroneously uses the reservation register command.

Fix these errors. Note that NVMe version 1.3 and later specify
that setting the IEKEY field will return an error of Invalid
Field in Command.  The fix will set IEKEY when the key is zero,
which is appropriate as these ioctls consider a zero key to
be "unspecified", and the intention of the spec change is
to require a valid key.

Tested on a version 1.4 PCI NVMe device in an Azure VM.

This reverts commit a09b314005f3a0956ebf56e01b3b80339df577cc.

Dusty Mabe reported consistent hang during CoreOS shutdown with a MD
RAID1 setup.  Although apparently similar hangs happened before,
and this patch most likely is not the root cause it made it much
more severe.  Revert it until we can figure out what is going on
with the md driver.

db7ba07108 s390/dasd: fix Oops in dasd_alias_get_start_dev due to missing pavgroup
Fix Oops in dasd_alias_get_start_dev() function caused by the pavgroup
pointer being NULL.

The pavgroup pointer is checked on the entrance of the function but
without the lcu->lock being held. Therefore there is a race window
between dasd_alias_get_start_dev() and _lcu_update() which sets
pavgroup to NULL with the lcu->lock held.

Fix by checking the pavgroup pointer with lcu->lock held.

c4fa368466 blk-lib: fix blkdev_issue_secure_erase
There's a bug in blkdev_issue_secure_erase. The statement
"unsigned int len = min_t(sector_t, nr_sects, max_sectors);"
sets the variable "len" to the length in sectors, but the statement
"bio->bi_iter.bi_size = len" treats it as if it were in bytes.
The statements "sector += len << SECTOR_SHIFT" and "nr_sects -= len <<
SECTOR_SHIFT" are thinko.

This patch fixes it.

56f99b8d06 block: blk_queue_enter() / __bio_queue_enter() must return -EAGAIN for nowait
Today blk_queue_enter() and __bio_queue_enter() return -EBUSY for the
nowait code path. This is not correct: they should return -EAGAIN
instead.

This problem was detected by fio. The following command exposed the
above problem:

t/io_uring -p0 -d128 -b4096 -s32 -c32 -F1 -B0 -R0 -X1 -n24 -P1 -u1 -O0 /dev/ng0n1

By applying the patch, the retry case is handled correctly in the slow

b7e97872a6 nvmet: fix mar and mor off-by-one errors
Maximum Active Resources (MAR) and Maximum Open Resources (MOR) are 0's
based vales where a value of 0xffffffff indicates that there is no limit.

Decrement the values that are returned by bdev_max_open_zones and
bdev_max_active_zones as the block layer helpers are not 0's based.
A 0 returned by the block layer helpers indicates no limit, thus convert
it to 0xffffffff (U32_MAX).

3770a42bb8 nvme-tcp: fix regression that causes sporadic requests to time out
When we queue requests, we strive to batch as much as possible and also
signal the network stack that more data is about to be sent over a socket
with MSG_SENDPAGE_NOTLAST. This flag looks at the pending requests queued
as well as queue->more_requests that is derived from the block layer
last-in-batch indication.

We set more_request=true when we flush the request directly from
.queue_rq submission context (in nvme_tcp_send_all), however this is
wrongly assuming that no other requests may be queued during the
execution of nvme_tcp_send_all.

Due to this, a race condition may happen where:

 1. request X is queued as !last-in-batch
 2. request X submission context calls nvme_tcp_send_all directly
 3. nvme_tcp_send_all is preempted and schedules to a different cpu
 4. request Y is queued as last-in-batch
 5. nvme_tcp_send_all context sends request X+Y, however signals for
    both MSG_SENDPAGE_NOTLAST because queue->more_requests=true.

==> none of the requests is pushed down to the wire as the network
stack is waiting for more data, both requests timeout.

To fix this, we eliminate queue->more_requests and only rely on
the queue req_list and send_list to be not-empty.

Commit b9684a71fca7 ("block, loop: support partitions without scanning")
adds GD_SUPPRESS_PART_SCAN for replacing part function of
GENHD_FL_NO_PART. But looks blk_add_partitions() is missed, since
loop doesn't want to add partitions if GENHD_FL_NO_PART was set.
And it causes regression on libblockdev (as called from udisks) which
operates with the LO_FLAGS_PARTSCAN.

Fixes the issue by not adding partitions if GD_SUPPRESS_PART_SCAN is
set.

This reverts commit e151db8ecfb019b7da31d076130a794574c89f6f. Because it
obviously breaks clustered raid as noticed by Neil though it fixed KASAN
issue for dm-raid, let's revert it and fix KASAN issue in next commit.

5e8daf906f md: Flush workqueue md_rdev_misc_wq in md_alloc()
A race condition still exists when removing and re-creating md devices
in test cases. However, it is only seen on some setups.

The race condition was tracked down to a reference still being held
to the kobject by the rdev in the md_rdev_misc_wq which will be released
in rdev_delayed_delete().

md_alloc() waits for previous deletions by waiting on the md_misc_wq,
but the md_rdev_misc_wq may still be holding a reference to a recently
removed device.

To fix this, also flush the md_rdev_misc_wq in md_alloc().

c490a0b5a4 loop: Check for overflow while configuring loop
The userspace can configure a loop using an ioctl call, wherein
a configuration of type loop_config is passed (see lo_ioctl()'s
case on line 1550 of drivers/block/loop.c). This proceeds to call
loop_configure() which in turn calls loop_set_status_from_info()
(see line 1050 of loop.c), passing &config->info which is of type
loop_info64*. This function then sets the appropriate values, like
the offset.

loop_device has lo_offset of type loff_t (see line 52 of loop.c),
which is typdef-chained to long long, whereas loop_info64 has
lo_offset of type __u64 (see line 56 of include/uapi/linux/loop.h).

The function directly copies offset from info to the device as
follows (See line 980 of loop.c):
	lo->lo_offset = info->lo_offset;

This results in an overflow, which triggers a warning in iomap_iter()
due to a call to iomap_iter_done() which has:
	WARN_ON_ONCE(iter->iomap.offset > iter->pos);

Thus, check for negative value during loop_set_status_from_info().

65fac0d54f blk-mq: fix io hung due to missing commit_rqs
Currently, in virtio_scsi, if 'bd->last' is not set to true while
dispatching request, such io will stay in driver's queue, and driver
will wait for block layer to dispatch more rqs. However, if block
layer failed to dispatch more rq, it should trigger commit_rqs to
inform driver.

There is a problem in blk_mq_try_issue_list_directly() that commit_rqs
won't be called:

// assume that queue_depth is set to 1, list contains two rq
blk_mq_try_issue_list_directly
 blk_mq_request_issue_directly
 // dispatch first rq
 // last is false
  __blk_mq_try_issue_directly
   blk_mq_get_dispatch_budget
   // succeed to get first budget
   __blk_mq_issue_directly
    scsi_queue_rq
     cmd->flags |= SCMD_LAST
      virtscsi_queuecommand
       kick = (sc->flags & SCMD_LAST) != 0
       // kick is false, first rq won't issue to disk
 queued++

 blk_mq_request_issue_directly
 // dispatch second rq
  __blk_mq_try_issue_directly
   blk_mq_get_dispatch_budget
   // failed to get second budget
 ret == BLK_STS_RESOURCE
  blk_mq_request_bypass_insert
 // errors is still 0

 if (!list_empty(list) || errors && ...)
  // won't pass, commit_rqs won't be called

In this situation, first rq relied on second rq to dispatch, while
second rq relied on first rq to complete, thus they will both hung.

Fix the problem by also treat 'BLK_STS_*RESOURCE' as 'errors' since
it means that request is not queued successfully.

Same problem exists in blk_mq_dispatch_rq_list(), 'BLK_STS_*RESOURCE'
can't be treated as 'errors' here, fix the problem by calling
commit_rqs if queue_rq return 'BLK_STS_*RESOURCE'.

d3b3859687 blk-mq: run queue no matter whether the request is the last request
We do test on a virtio scsi device (/dev/sda) and the default mq
scheduler is 'none'. We found a IO hung as following:

blk_finish_plug
  blk_mq_plug_issue_direct
      scsi_mq_get_budget
      //get budget_token fail and sdev->restarts=1

			     	 scsi_end_request
				   scsi_run_queue_async
                                   //sdev->restart=0 and run queue

     blk_mq_request_bypass_insert
        //add request to hctx->dispatch list

  //continue to dispath plug list
  blk_mq_dispatch_plug_list
      blk_mq_try_issue_list_directly
        //success issue all requests from plug list

After .get_budget fail, scsi_mq_get_budget will increase 'restarts'.
Normally, it will run hw queue when io complete and set 'restarts'
as 0. But if we run queue before adding request to the dispatch list
and blk_mq_dispatch_plug_list also success issue all requests, then
on one will run queue, and the request will be stall in the dispatch
list and cannot complete forever.

It is wrong to use last request of plug list to decide if run queue is
needed since all the remained requests in plug list may be from other
hctxs. To fix the bug, pass run_queue as true always to
blk_mq_request_bypass_insert().

e6190dd003 ublk_drv: do not add a re-issued request aborted previously to ioucmd's task_work
In ublk_queue_rq(), Assume current request is a re-issued request aborted
previously in monitor_work because the ubq_daemon(ioucmd's task) is
PF_EXITING. For this request, we cannot call
io_uring_cmd_complete_in_task() anymore because at that moment io_uring
context may be freed in case that no inflight ioucmd exists. Otherwise,
we may cause null-deref in ctx->fallback_work.

Add a check on UBLK_IO_FLAG_ABORTED to prevent the above situation. This
check is safe and makes sense.

Note: monitor_work sets UBLK_IO_FLAG_ABORTED and ends this request
(releasing the tag). Then the request is restarted(allocating the tag)
and we are here. Since releasing/allocating a tag implies smp_mb(),
finding UBLK_IO_FLAG_ABORTED guarantees that here is a re-issued request
aborted previously.

Commit 6f8191fdf41d ("block: simplify disk shutdown") removed the call
to blk_get_queue() during gendisk allocation but missed to remove the
corresponding cleanup code blk_put_queue() for it. Thus, if the gendisk
allocation fails, the request_queue refcount gets decremented and
reaches 0, causing blk_mq_release() to be called with a hctx still
alive. That triggers a WARNING report, as found by syzkaller:

2bff487f9a nvme-tcp: check if the queue is allocated before stopping it
When an error is detected and the host reconnects, the
nvme_tcp_error_recovery_work() function is called and starts
tearing down the io queues and de-allocating them;
If at the same time the "nvme" process deletes the controller via sysfs,
the nvme_tcp_delete_ctrl() gets called and waits until the
nvme_tcp_error_recovery_work() finishes its job; then starts
tearing down the io queues, but at this point they have already
been freed and the mutexes are destroyed.

Calling mutex_lock() against a destroyed mutex triggers a warning:

746fc76b82 SCSI misc on 20220804
Updates to the usual drivers (ufs, qla2xx, target, lpfc, smartpqi,
 mpi3mr).  The main driver change that might cause issues on down the
 road is the conversion of some of our oldest surviving drivers to the
 DMA API (should only affect m68k).  The only major core change is the
 rework of async resume; the rest are either completely trivial or for
 updating deprecated APIs.

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Consolidate duplicated 'next function' scanning and extend to allow
     'isolated functions' on s390, similar to existing hypervisors
     (Niklas Schnelle)

  Resource management:
   - Implement pci_iobar_pfn() for sparc, which allows us to remove the
     sparc-specific pci_mmap_page_range() and pci_mmap_resource_range().

     This removes the ability to map the entire PCI I/O space using
     /proc/bus/pci, but we believe that's already been broken since
     v2.6.28 (Arnd Bergmann)

   - Move common PCI definitions to asm-generic/pci.h and rework others
     to be be more specific and more encapsulated in arches that need
     them (Stafford Horne)

  Power management:

   - Convert drivers to new *_PM_OPS macros to avoid need for '#ifdef
     CONFIG_PM_SLEEP' or '__maybe_unused' (Bjorn Helgaas)

  Virtualization:

   - Add ACS quirk for Broadcom BCM5750x multifunction NICs that isolate
     the functions but don't advertise an ACS capability (Pavan Chebbi)

  Error handling:

   - Clear PCI Status register during enumeration in case firmware left
     errors logged (Kai-Heng Feng)

   - When we have native control of AER, enable error reporting for all
     devices that support AER. Previously only a few drivers enabled
     this (Stefan Roese)

   - Keep AER error reporting enabled for switches. Previously we
     enabled this during enumeration but immediately disabled it (Stefan
     Roese)

   - Iterate over error counters instead of error strings to avoid
     printing junk in AER sysfs counters (Mohamed Khalfella)

  ASPM:

   - Remove pcie_aspm_pm_state_change() so ASPM config changes, e.g.,
     via sysfs, are not lost across power state changes (Kai-Heng Feng)

  Endpoint framework:

   - Don't stop an EPC when unbinding an EPF from it (Shunsuke Mie)

  Endpoint embedded DMA controller driver:

   - Simplify and clean up support for the DesignWare embedded DMA
     (eDMA) controller (Frank Li, Serge Semin)

  Broadcom STB PCIe controller driver:

   - Avoid config space accesses when link is down because we can't
     recover from the CPU aborts these cause (Jim Quinlan)

   - Look for power regulators described under Root Ports in DT and
     enable them before scanning the secondary bus (Jim Quinlan)

   - Disable/enable regulators in suspend/resume (Jim Quinlan)

  Freescale i.MX6 PCIe controller driver:

   - Simplify and clean up clock and PHY management (Richard Zhu)

   - Disable/enable regulators in suspend/resume (Richard Zhu)

   - Set PCIE_DBI_RO_WR_EN before writing DBI registers (Richard Zhu)

   - Allow speeds faster than Gen2 (Richard Zhu)

   - Make link being down a non-fatal error so controller probe doesn't
     fail if there are no Endpoints connected (Richard Zhu)

  Loongson PCIe controller driver:

   - Add ACPI and MCFG support for Loongson LS7A (Huacai Chen)

   - Avoid config reads to non-existent LS2K/LS7A devices because a
     hardware defect causes machine hangs (Huacai Chen)

   - Work around LS7A integrated devices that report incorrect Interrupt
     Pin values (Jianmin Lv)

  Marvell Aardvark PCIe controller driver:

   - Add support for AER and Slot capability on emulated bridge (Pali
     Rohár)

  MediaTek PCIe controller driver:

   - Add Airoha EN7532 to DT binding (John Crispin)

   - Allow building of driver for ARCH_AIROHA (Felix Fietkau)

  MediaTek PCIe Gen3 controller driver:

   - Print decoded LTSSM state when the link doesn't come up (Jianjun
     Wang)

  NVIDIA Tegra194 PCIe controller driver:

   - Convert DT binding to json-schema (Vidya Sagar)

   - Add DT bindings and driver support for Tegra234 Root Port and
     Endpoint mode (Vidya Sagar)

   - Fix some Root Port interrupt handling issues (Vidya Sagar)

   - Set default Max Payload Size to 256 bytes (Vidya Sagar)

   - Fix Data Link Feature capability programming (Vidya Sagar)

   - Extend Endpoint mode support to devices beyond Controller-5 (Vidya
     Sagar)

  Qualcomm PCIe controller driver:

   - Rework clock, reset, PHY power-on ordering to avoid hangs and
     improve consistency (Robert Marko, Christian Marangi)

   - Move pipe_clk handling to PHY drivers (Dmitry Baryshkov)

   - Add IPQ60xx support (Selvam Sathappan Periakaruppan)

   - Allow ASPM L1 and substates for 2.7.0 (Krishna chaitanya chundru)

   - Add support for more than 32 MSI interrupts (Dmitry Baryshkov)

  Renesas R-Car PCIe controller driver:

   - Convert DT binding to json-schema (Herve Codina)

   - Add Renesas RZ/N1D (R9A06G032) to rcar-gen2 DT binding and driver
     (Herve Codina)

  Samsung Exynos PCIe controller driver:

36001a2fa6 The clk core gains a new set of APIs that allow drivers to both acquire clks
and prepare and enable them at the same time. This also comes with devm support
 so that drivers can make a single call to get and prepare and enable the clk
 and have that all undone when their driver is removed. Many folks have
 requested this feature over the years, but we've had disagreements about how to
 implement it and if it was worthwhile to encourage drivers to use such an API.
 Now it's here, so let's see how it goes. I hope that by introducing this API we
 can identify drivers that would benefit from further consolidation of clk API
 usage, possibly by moving such logic to the bus layer and out of drivers
 altogether.
 
 Outside of that major API update, we have the usual collection of driver
 updates. A few new SoCs are supported, mostly Qualcomm and Renesas this time
 around. Then we have the long tail of non-critical fixes and minor feature
 additions to various clk drivers. And finally more clk provider migration to
 struct clk_parent_data, reducing boot times in the process.
 
 Core:
  - devm helpers for clk_get() + clk_prepare() and clk_enable()
 
 New Drivers:
  - Support for the camera clock controller in Qualcomm SM8450 and
    the display and gpu clock controllers in Qualcomm SM8350
  - Add support for the Renesas RZ/Five SoC
 
 Updates:
  - Various fixes, new clocks and USB GDSCs are introduced for Qualcomm IPQ8074
  - Fixes to Qualcomm MSM8939 for issues introduced by inheriting the MSM8916
    GCC driver
  - Support for a new type of voteable GDSCs used by Qualcomm SC8280XP PCIe
    GDSCs
  - Qualcomm SC8280XP pipe clocks transitioned to the new phy-mux implementation
  - Qualcomm MSM8996 GCC, RPM clock driver and some clocks in MSM8994 GCC are
    migrated to use clk_parent_data
  - Corrected the topology for Titan (camera) GDSCs on Qualcomm SDM845 and
    SM8250
  - Qualcomm MSM8916 gains more possible frequencies for its GP clocks.
  - The GCC and tsens handling on Qualcomm MSM8960 is reworked to mimic the
    design in IPQ8074 to allow the GCC driver to probe earlier.
  - The regulator based mmcx supply for Qualcomm dispcc and videocc is dropped,
    as the only upstream target that adapted this interface was transitioned
    several kernel versions ago
  - Qualcomm GDSCs found to be enabled at boot will now reflect in the enable
    count of the supply, as was done with the regulator supplies previously
  - Correct adc1, nic_media and edma1's parents for NXP i.MX93
  - rdiv, mfd values, the return rate in recalc_rate and add more frequencies in
    the table for fracn-gppll on i.MX
  - Remove Allwinner workaround logic/compatible in fixed factor code
  - MediaTek clk driver cleanups
  - Add reset support to more MediaTek clk drivers
  - deduplicate Allwinner ccu_clks arrays
  - Allwinner H6 GPU DFS support
  - Adjust Allwinner Kconfig to limit choice
  - Fix initconst confusion on Renesas R-Car Gen4
  - Add GPT/POEG (PWM) clocks and resets on Renesas RZ/G2L
  - Add PFC and WDT clocks and resets on Renesas RZ/V2M
  - Add thermal, SDHI, Z (CPU core), PCIe, and HSCIF (serial) clocks on
    Renesas R-Car S4-8
