578539e096 nvme-tcp: fix connect failure on receiving partial ICResp PDU
nvme_tcp_init_connection() attempts to receive an ICResp PDU but only
checks that the return value from recvmsg() is non-negative. If the
sender closes the TCP connection or sends fewer than 128 bytes, this
check will pass even though the full PDU wasn't received.

Ensure the full ICResp PDU is received by checking that recvmsg()
returns the expected 128 bytes.

Additionally set the MSG_WAITALL flag for recvmsg(), as a sender could
split the ICResp over multiple TCP frames. Without MSG_WAITALL,
recvmsg() could return prematurely with only part of the PDU.

01ef7ff7dd nvmet: pci-epf: Avoid RCU stalls under heavy workload
The delayed work item function nvmet_pci_epf_poll_sqs_work() polls all
submission queues and keeps running in a loop as long as commands are
being submitted by the host. Depending on the preemption configuration
of the kernel, under heavy command workload, this function can thus run
for more than RCU_CPU_STALL_TIMEOUT seconds, leading to a RCU stall:

The solution for this is simply to explicitly allow rescheduling using
cond_resched(). However, since doing so for every loop of
nvmet_pci_epf_poll_sqs_work() significantly degrades performance
(for 4K random reads using 4 I/O queues, the maximum IOPS goes down from
137 KIOPS to 110 KIOPS), call cond_resched() every second to avoid the
RCU stalls.

ffa3556763 nvmet: pci-epf: Do not uselessly write the CSTS register
The function nvmet_pci_epf_poll_cc_work() will do nothing if there are
no changes to the controller configuration (CC) register. However, even
for such case, this function still calls nvmet_update_cc() and uselessly
writes the CSTS register. Avoid this by simply rescheduling the poll_cc
work if the CC register has not changed.

Also reschedule the poll_cc work if the function
nvmet_pci_epf_enable_ctrl() fails to allow the host the chance to try
again enabling the controller.

While at it, since there is no point in trying to handle the CC register
as quickly as possible, change the poll_cc work scheduling interval to
10 ms (from 5ms), to avoid excessive read accesses to that register.

68a5c91f01 nvmet: pci-epf: Correctly initialize CSTS when enabling the controller
The function nvmet_pci_epf_poll_cc_work() sets the NVME_CSTS_RDY bit of
the controller status register (CSTS) when nvmet_pci_epf_enable_ctrl()
returns success. However, since this function can be called several
times (e.g. if the host reboots), instead of setting the bit in
ctrl->csts, initialize this field to only have NVME_CSTS_RDY set.
Conversely, if nvmet_pci_epf_enable_ctrl() fails, make sure to clear all
bits from ctrl->csts.

To simplify nvmet_pci_epf_poll_cc_work(), initialize ctrl->csts to
NVME_CSTS_RDY directly inside nvmet_pci_epf_enable_ctrl() and clear this
field in that function as well in case of a failure. To be consistent,
move clearing the NVME_CSTS_RDY bit from ctrl->csts when the controller
is being disabled from nvmet_pci_epf_poll_cc_work() into
nvmet_pci_epf_disable_ctrl().

as the queue is already torn down when calling submit_bio();

So we need to init the percpu counter in nvmet_ns_enable(), and
wait for it to drop to zero in nvmet_ns_disable() to avoid having
I/O pending after the namespace has been disabled.

fcd8754458 nvme-pci: quirk Acer FA100 for non-uniqueue identifiers
In order for two Acer FA100 SSDs to work in one PC (in the case of
myself, a Lenovo Legion T5 28IMB05), and not show one drive and not
the other, and sometimes mix up what drive shows up (randomly), these
two lines of code need to be added, and then both of the SSDs will
show up and not conflict when booting off of one of them. If you boot
up your computer with both SSDs installed without this patch, you may
also randomly get into a kernel panic (if the initrd is not set up) or
stuck in the initrd "/init" process, it is set up, however, if you do
apply this patch, there should not be problems with booting or seeing
both contents of the drive. Tested with the btrfs filesystem with a
RAID configuration of having the root drive '/' combined to make two
256GB Acer FA100 SSDs become 512GB in total storage.

 - The bailout for a bad partoffset must use put_dev_sector(), since the

 - If the partition table claims a silly sector size like 0xfff bytes
   (which results in partition table entries straddling sector boundaries),
   bail out instead of accessing out-of-bounds memory.
 - We must not assume that the partition table contains proper NUL
   termination - use strnlen() and strncmp() instead of strlen() and

1f47ed294a block: cleanup and fix batch completion adding conditions
The conditions for whether or not a request is allowed adding to a
completion batch are a bit hard to read, and they also have a few
issues. One is that ioerror may indeed be a random value on passthrough,
and it's being checked unconditionally of whether or not the given
request is a passthrough request or not.

Rewrite the conditions to be separate for easier reading, and only check
ioerror for non-passthrough requests. This fixes an issue with bio
unmapping on passthrough, where it fails getting added to a batch. This
both leads to suboptimal performance, and may trigger a potential
schedule-under-atomic condition for polled passthrough IO.

1e1a9cecfa block: force noio scope in blk_mq_freeze_queue
When block drivers or the core block code perform allocations with a
frozen queue, this could try to recurse into the block device to
reclaim memory and deadlock.  Thus all allocations done by a process
that froze a queue need to be done without __GFP_IO and __GFP_FS.
Instead of tying to track all of them down, force a noio scope as
part of freezing the queue.

Note that nvme is a bit of a mess here due to the non-owner freezes,
and they will be addressed separately.

14ef49657f block: fix nr_hw_queue update racing with disk addition/removal
The nr_hw_queue update could potentially race with disk addtion/removal
while registering/unregistering hctx sysfs files. The __blk_mq_update_
nr_hw_queues() runs with q->tag_list_lock held and so to avoid it racing
with disk addition/removal we should acquire q->tag_list_lock while
registering/unregistering hctx sysfs files.

With this patch, blk_mq_sysfs_register() (called during disk addition)
and blk_mq_sysfs_unregister() (called during disk removal) now runs
with q->tag_list_lock held so that it avoids racing with __blk_mq_update
_nr_hw_queues().

fe66286086 block: get rid of request queue ->sysfs_dir_lock
The request queue uses ->sysfs_dir_lock for protecting the addition/
deletion of kobject entries under sysfs while we register/unregister
blk-mq. However kobject addition/deletion is already protected with
kernfs/sysfs internal synchronization primitives. So use of q->sysfs_
dir_lock seems redundant.

Moreover, q->sysfs_dir_lock is also used at few other callsites along
with q->sysfs_lock for protecting the addition/deletion of kojects.
One such example is when we register with sysfs a set of independent
access ranges for a disk. Here as well we could get rid off q->sysfs_
dir_lock and only use q->sysfs_lock.

The only variable which q->sysfs_dir_lock appears to protect is q->
mq_sysfs_init_done which is set/unset while registering/unregistering
blk-mq with sysfs. But use of q->mq_sysfs_init_done could be easily
replaced using queue registered bit QUEUE_FLAG_REGISTERED.

So with this patch we remove q->sysfs_dir_lock from each callsite
and replace q->mq_sysfs_init_done using QUEUE_FLAG_REGISTERED.

ee59e3820c nvme-fc: do not ignore connectivity loss during connecting
When a connectivity loss occurs while nvme_fc_create_assocation is
being executed, it's possible that the ctrl ends up stuck in the LIVE
state:

  1) nvme nvme10: NVME-FC{10}: create association : ...
  2) nvme nvme10: NVME-FC{10}: controller connectivity lost.
                  Awaiting Reconnect
     nvme nvme10: queue_size 128 > ctrl maxcmd 32, reducing to maxcmd
  3) nvme nvme10: Could not set queue count (880)
     nvme nvme10: Failed to configure AEN (cfg 900)
  4) nvme nvme10: NVME-FC{10}: controller connect complete
  5) nvme nvme10: failed nvme_keep_alive_end_io error=4

A connection attempt starts 1) and the ctrl is in state CONNECTING.
Shortly after the LLDD driver detects a connection lost event and calls
nvme_fc_ctrl_connectivity_loss 2). Because we are still in CONNECTING
state, this event is ignored.

nvme_fc_create_association continues to run in parallel and tries to
communicate with the controller and these commands will fail. Though
these errors are filtered out, e.g in 3) setting the I/O queues numbers
fails which leads to an early exit in nvme_fc_create_io_queues. Because
the number of IO queues is 0 at this point, there is nothing left in
nvme_fc_create_association which could detected the connection drop.
Thus the ctrl enters LIVE state 4).

Eventually the keep alive handler times out 5) but because nothing is
being done, the ctrl stays in LIVE state.

There is already the ASSOC_FAILED flag to track connectivity loss event
but this bit is set too late in the recovery code path. Move this into
the connectivity loss event handler and synchronize it with the state
change. This ensures that the ASSOC_FAILED flag is seen by
nvme_fc_create_io_queues and it does not enter the LIVE state after a
connectivity loss event. If the connectivity loss event happens after we
entered the LIVE state the normal error recovery path is executed.

294b2b7516 nvme: handle connectivity loss in nvme_set_queue_count
When the set feature attempts fails with any NVME status code set in
nvme_set_queue_count, the function still report success. Though the
numbers of queues set to 0. This is done to support controllers in
degraded state (the admin queue is still up and running but no IO
queues).

Though there is an exception. When nvme_set_features reports an host
path error, nvme_set_queue_count should propagate this error as the
connectivity is lost, which means also the admin queue is not working
anymore.

d3d380eded nvme-fc: go straight to connecting state when initializing
The initial controller initialization mimiks the reconnect loop
behavior by switching from NEW to RESETTING and then to CONNECTING.

The transition from NEW to CONNECTING is a valid transition, so there is
no point entering the RESETTING state. TCP and RDMA also transition
directly to CONNECTING state.

a9ae6fe1c3 blk-mq: create correct map for fallback case
The fallback code in blk_mq_map_hw_queues is original from
blk_mq_pci_map_queues and was added to handle the case where
pci_irq_get_affinity will return NULL for !SMP configuration.

blk_mq_map_hw_queues replaces besides blk_mq_pci_map_queues also
blk_mq_virtio_map_queues which used to use blk_mq_map_queues for the
fallback.

It's possible to use blk_mq_map_queues for both cases though.
blk_mq_map_queues creates the same map as blk_mq_clear_mq_map for !SMP
that is CPU 0 will be mapped to hctx 0.

The WARN_ON_ONCE has to be dropped for virtio as the fallback is also
taken for certain configuration on default. Though there is still a
WARN_ON_ONCE check in lib/group_cpus.c:

       WARN_ON(nr_present + nr_others < numgrps);

which will trigger if the caller tries to create more hardware queues
than CPUs. It tests the same as the WARN_ON_ONCE in
blk_mq_pci_map_queues did.

b13ee668e8 block: don't revert iter for -EIOCBQUEUED
blkdev_read_iter() has a few odd checks, like gating the position and
count adjustment on whether or not the result is bigger-than-or-equal to
zero (where bigger than makes more sense), and not checking the return
value of blkdev_direct_IO() before doing an iov_iter_revert(). The
latter can lead to attempting to revert with a negative value, which
when passed to iov_iter_revert() as an unsigned value will lead to
throwing a WARN_ON() because unroll is bigger than MAX_RW_COUNT.

Be sane and don't revert for -EIOCBQUEUED, like what is done in other
spots.

88e969fc18 Input updates for v6.14-rc0
- more conversions to the guard notation in the input core
 
 - a fix for NXP BBNSM power key driver to clean up wake IRQ after
   unbinding
 
 - several new vendor/device ID pairs added to xpad game controller
   driver
 
 - several drivers switched to using str_enable_disable and similar
   helpers instead of open-coding
 
 - add mapping for F23 to atkbd driver so that MS "Copilot" key shortcut
   works out of the box (if userspace is ready to handle it)
 
 - evbug input handler has been removed (debugging through evdev is
   strongly preferred to dumping all events into the kernel log).

Pull power management updates from Rafael Wysocki:
 "The majority of changes here are cpufreq updates which are dominated
  by amd-pstate driver changes, like in the previous cycle. Moreover,

  Included are some pieces of new hardware support, like the addition of
  Clearwater Forest processors support to intel_idle, new cpufreq driver
  for Airoha SoCs, and Apple cpufreq driver extensions to support more
  SoCs. The intel_pstate driver is also extended to be able to support
  new platforms by using ACPI CPPC to compute scaling factors between
  HWP performance states and frequency.

641b0c64b8 A pretty quiet cycle this time around. We have a bunch of new Qualcomm clk
drivers, per usual, and then a handful of drivers for other SoCs. Then the
 usual pile of cleanups is fairly small data fixes or converting DT bindings to
 YAML so they can be validated. No changes to the core framework besides an OF
 node refcount bump that never got decremented.
 
 New Drivers:
  - 5L35023 variant of Versa 3 clock generator
  - Various Qualcomm clk controllers: IPQ CMN PLL, SM6115 LPASS, SM750 global,
    tcsr, rpmh, and display. X Plus GPU and global. QCS615 rpmh and MSM8937 and
    MSM8940 RPM.
  - Qualcomm Pongo and Taycan Alpha PLLs
  - Qualcomm IPQ5424 NoC-related interconnect clks
  - Renesas RZ/G3E (R9A09G047) SoC clk driver
  - SAMA7D65 SoC clk driver

38f5265ed2 spi: Updates for v6.14
This is a fairly quiet release for the most part, though we do have one
 really nice improvement in the spi-mem framework which will improve
 performance for flash devices especially when built on by changes in the
 MTD subsystem which are also due to be sent this merge window.  There's
 also been some substantial work on some of the drivers, highlights
 include:
 
  - Support for per-operation bus frequency in the spi-mem framework,
    meaning speeds are no longer limited by the slowest operation.
  - ACPI support and improved power management for Rockchip SFC
    controllers.
  - Support for Atmel SAM7G5 QuadSPI and KEBA SPI controllers.
