884f0e84f1 blk-throttle: fix UAF by deleteing timer in blk_throtl_exit()
The pending timer has been set up in blk_throtl_init(). However, the
timer is not deleted in blk_throtl_exit(). This means that the timer
handler may still be running after freeing the timer, which would
result in a use-after-free.

Fix by calling del_timer_sync() to delete the timer in blk_throtl_exit().

Commit 1c500ad706 ("loop: reduce the loop_ctl_mutex scope") is for
breaking "loop_ctl_mutex => &lo->lo_mutex" dependency chain. But enabling
a different block module results in forming circular locking dependency
due to shared major_names_lock mutex.

The simplest fix is to call probe function without holding
major_names_lock [1], but Christoph Hellwig does not like such idea.
Therefore, instead of holding major_names_lock in blkdev_show(),
introduce a different lock for blkdev_show() in order to break
"sb_writers#$N => &p->lock => major_names_lock" dependency chain.

b58da2d270 nvme: update keep alive interval when kato is modified
Currently the connection between host and NVMe-oF target gets
disconnected by keep-alive timeout when a user connects to a target
with a relatively large kato value and then sets the smaller kato
with a set features command (e.g. connects with 60 seconds kato value
and then sets 10 seconds kato value).

The cause is that keep alive command interval on the host, which is
defined as unsigned int kato in nvme_ctrl structure, does not follow
the kato value changes.

This patch updates the keep alive interval in the following steps when
the kato is modified by a set features command: stops the keep alive
work queue, then sets the kato as new timer value and re-start the queue.

1ba2e507f5 nvme-tcp: Do not reset transport on data digest errors
The spec says

  7.4.6.1 Digest Error handling

  When a host detects a data digest error in a C2HData PDU, that host
  shall continue processing C2HData PDUs associated with the command and
  when the command processing has completed, if a successful status was
  returned by the controller, the host shall fail the command with a
  non-fatal transport error.

Currently the transport is reseted when a data digest error is
detected. Instead, when a digest error is detected, mark the final
status as NVME_SC_DATA_XFER_ERROR and let the upper layer handle
the error.

In order to keep track of the final result maintain a status field in
nvme_tcp_request object and use it to overwrite the completion queue
status (which might be successful even though a digest error has been
detected) when completing the request.

e7d65803e2 nvme-multipath: revalidate paths during rescan
When triggering a rescan due to a namespace resize we will be
receiving AENs on every controller, triggering a rescan of all
attached namespaces. If multipath is active only the current path and
the ns_head disk will be updated, the other paths will still refer to
the old size until AENs for the remaining controllers are received.

If I/O comes in before that it might be routed to one of the old
paths, triggering an I/O failure with 'access beyond end of device'.
With this patch the old paths are skipped from multipath path
selection until the controller serving these paths has been rescanned.

d32d3d0b47 nvme-multipath: set QUEUE_FLAG_NOWAIT
The nvme multipathing code just dispatches bios to one of the blk-mq
based paths and never blocks on its own, so set QUEUE_FLAG_NOWAIT
to support REQ_NOWAIT bios.

1c500ad706 loop: reduce the loop_ctl_mutex scope
syzbot is reporting circular locking problem at __loop_clr_fd() [1], for
commit a160c6159d ("block: add an optional probe callback to
major_names") is calling the module's probe function with major_names_lock
held.

Fortunately, since commit 990e78116d ("block: loop: fix deadlock
between open and remove") stopped holding loop_ctl_mutex in lo_open(),
current role of loop_ctl_mutex is to serialize access to loop_index_idr
and loop_add()/loop_remove(); in other words, management of id for IDR.
To avoid holding loop_ctl_mutex during whole add/remove operation, use
a bool flag to indicate whether the loop device is ready for use.

loop_unregister_transfer() which is called from cleanup_cryptoloop()
currently has possibility of use-after-free problem due to lack of
serialization between kfree() from loop_remove() from loop_control_remove()
and mutex_lock() from unregister_transfer_cb(). But since lo->lo_encryption
should be already NULL when this function is called due to module unload,
and commit 222013f9ac ("cryptoloop: add a deprecation warning")
indicates that we will remove this function shortly, this patch updates
this function to emit warning instead of checking lo->lo_encryption.

Holding loop_ctl_mutex in loop_exit() is pointless, for all users must
close /dev/loop-control and /dev/loop$num (in order to drop module's
refcount to 0) before loop_exit() starts, and nobody can open
/dev/loop-control or /dev/loop$num afterwards.

2d52c58b9c block, bfq: honor already-setup queue merges
The function bfq_setup_merge prepares the merging between two
bfq_queues, say bfqq and new_bfqq. To this goal, it assigns
bfqq->new_bfqq = new_bfqq. Then, each time some I/O for bfqq arrives,
the process that generated that I/O is disassociated from bfqq and
associated with new_bfqq (merging is actually a redirection). In this
respect, bfq_setup_merge increases new_bfqq->ref in advance, adding
the number of processes that are expected to be associated with
new_bfqq.

Unfortunately, the stable-merging mechanism interferes with this
setup. After bfqq->new_bfqq has been set by bfq_setup_merge, and
before all the expected processes have been associated with
bfqq->new_bfqq, bfqq may happen to be stably merged with a different
queue than the current bfqq->new_bfqq. In this case, bfqq->new_bfqq
gets changed. So, some of the processes that have been already
accounted for in the ref counter of the previous new_bfqq will not be
associated with that queue.  This creates an unbalance, because those
references will never be decremented.

This commit fixes this issue by reestablishing the previous, natural
behaviour: once bfqq->new_bfqq has been set, it will not be changed
until all expected redirections have occurred.

   <debugfs>/printk/index/. It can be used when monitoring important
   kernel messages on a farm of various hosts. The monitor has to be
   updated when some messages has changed or are not longer available by
   a newly deployed kernel.

 - Add printk.console_no_auto_verbose boot parameter. It allows to
   generate crash dump even with slow consoles in a reasonable time
   frame.

 - Remove printk_safe buffers. The messages are always stored directly
   to the main logbuffer, even in NMI or recursive context. Also it
   allows to serialize syslog operations by a mutex instead of a spin
   lock.

7c636d4d20 ARM: SoC DT changes for 5.15
As usual, the bulk of work in the SoC tree goes into DT files,
 this time with a roughly even split between 32-bit and 64-bit
 SoCs rather than the usual mostly 64-bit changes.
 
 New SoCs:
 
  - Microchip SAMA7 SoC family based on Cortex-A7, a new
    32-bit platform based on the older SAMA5 series.
 
  - Qualcomm Snapdragon SDM636 and SM8150, variations of the
    existing phone SoCs.
 
  - Renesas R-Car H3e-2G and M3e-2G SoCs, variations of
    older Renesas SoCs.
 
 New boards:
 
  - Marvell CN913x reference boards
 
  - ASpeed AST2600 BMC implementations for Facebook Cloudripper,
    Elbert and Fuji server boards.
 
  - Snapdragon 665 based Sony Xperia 10II
 
  - Snapdragon MSM8916 based Xiaomi Redmi 2
 
  - Snapdragon MSM8226 based Samsung Galaxy S3 Neo
 
  - NXP i.MX based 32-bit boards:
    - DHCOM based PicoITX

 "As usual, the bulk of work in the SoC tree goes into DT files, this
  time with a roughly even split between 32-bit and 64-bit SoCs rather
  than the usual mostly 64-bit changes.

  New SoCs:

   - Microchip SAMA7 SoC family based on Cortex-A7, a new 32-bit
     platform based on the older SAMA5 series.

   - Qualcomm Snapdragon SDM636 and SM8150, variations of the existing
     phone SoCs.

634135a07b ARM: SoC updates for 5.15
There are three noteworthy updates for 32-bit arm platforms this time:
 
  - The Microchip SAMA7 family based on Cortex-A7 gets introduced, a new
    cousin to the older SAM9 (ARM9xx based) and SAMA5 (Cortex-A5 based)
    SoCs.
 
  - The ixp4xx platform (based on Intel XScale) is finally converted to
    device tree, and all the old board files are getting removed now.
 
  - The Cirrus Logic EP93xx platform loses support for the old
    MaverickCrunch FPU. Support for compiling user space applications
    was already removed in gcc-4.9, and the kernel support for old
    applications could not be built with clang ias. After confirming
    that there are no remaining users, removing this from the kernel
    seemed better than adding support for unused features to clang.
 
 There are minor updates to the aspeed, omap and samsung platforms

4cdc4cc2ad asm-generic changes for 5.15
The main content for 5.15 is a series that cleans up the handling of
 strncpy_from_user() and strnlen_user(), removing a lot of slightly
 incorrect versions of these in favor of the lib/strn*.c helpers
 that implement these correctly and more efficiently.
 
 The only architectures that retain a private version now are
 mips, ia64, um and parisc. I had offered to convert those at all,
 but Thomas Bogendoerfer wanted to keep the mips version for the
 moment until he had a chance to do regression testing.
 
 The branch also contains two patches for bitops and for ffs().

Pull exit cleanups from Eric Biederman:
 "In preparation of doing something about PTRACE_EVENT_EXIT I have
  started cleaning up various pieces of code related to do_exit. Most of
  that code I did not manage to get tested and reviewed before the merge
  window opened but a handful of very useful cleanups are ready to be
  merged.

  The first change is simply the removal of the bdflush system call. The
  code has now been disabled long enough that even the oldest userspace
  working userspace setups anyone can find to test are fine with the
  bdflush system call being removed.

  Changing m68k fsp040_die to use force_sigsegv(SIGSEGV) instead of
  calling do_exit directly is interesting only in that it is nearly the
  most difficult of the incorrect uses of do_exit to remove.

  The change to the seccomp code to simply send a signal instead of
  calling do_coredump directly is a very nice little cleanup made
  possible by realizing the existing signal sending helpers were missing
  a little bit of functionality that is easy to provide"

 "Highlights:

   - i915 has seen a lot of refactoring and uAPI cleanups due to a
     change in the upstream direction going forward

     This has all been audited with known userspace, but there may be
     some pitfalls that were missed.

   - i915 now uses common TTM to enable discrete memory on DG1/2 GPUs

   - i915 enables Jasper and Elkhart Lake by default and has preliminary
     XeHP/DG2 support

   - amdgpu adds support for Cyan Skillfish

   - lots of implicit fencing rules documented and fixed up in drivers

   - msm now uses the core scheduler

   - the irq midlayer has been removed for non-legacy drivers

   - the sysfb code now works on more than x86.

  Otherwise the usual smattering of stuff everywhere, panels, bridges,
  refactorings.

  Detailed summary:

  core:
   - extract i915 eDP backlight into core

0d290223a6 sound updates for 5.15-rc1
There are a few intensive changes in ALSA core side at this time that
 helped the significant code reduction.  Meanwhile we keep getting new
 stuff, so the total size still grows...
 Anyway, the below are some highlights in this development cycle.
 
 ALSA core:
 - New helpers to manage page allocations and card object with devres
 - Refactoring for memory allocation with wc-pages
 - A new PCM hardware flag SNDRV_PCM_INFO_EXPLICIT_SYNC for controlling
   the explicit sync of the stream control; it'll be used for ASoC SOF
   and non-coherent memory in future
 
 ASoC:
 - Lots of cleanups and improvements to the Intel drivers, including
   some new systems support
 - New support for AMD Vangoh, CUI CMM-4030D-261, Mediatek Mt8195,
   Renesas RZ/G2L Mediatek Mt8195, RealTek RT101P, Renesas RZ/G2L,
   Rockchip RK3568 S/PDIF
 
 USB-audio:
 - Re-organized the quirk handling and  a new option quirk_flags
 - Fix for a regression in 5.14 code change for JACK
 - Quirks for Sony WALKMAN, Digidesign mbox
 
 HD-audio:
 - Enhanced support for CS8409 codec
 - More consistent shutdown behavior with the runtime PM
 - The model option can accept the PCI or codec SSID as an alias
 - Quirks for ASUS ROG, HP Spectre x360
 
 Others:
 - Lots of code reduction in legacy drivers with devres helpers
 - FireWire MOTU 896HD support

ea7b4244b3 x86/setup: Explicitly include acpi.h
After commit 342f43af70 ("iscsi_ibft: fix crash due to KASLR physical
memory remapping") x86_64_defconfig shows the following errors:

  arch/x86/kernel/setup.c: In function ‘setup_arch’:
  arch/x86/kernel/setup.c:916:13: error: implicit declaration of function ‘acpi_mps_check’ [-Werror=implicit-function-declaration]
    916 |         if (acpi_mps_check()) {
        |             ^~~~~~~~~~~~~~
  arch/x86/kernel/setup.c:1110:9: error: implicit declaration of function ‘acpi_table_upgrade’ [-Werror=implicit-function-declaration]
   1110 |         acpi_table_upgrade();
        |         ^~~~~~~~~~~~~~~~~~
  [... more acpi noise ...]

acpi.h was being implicitly included from iscsi_ibft.h in this
configuration so the removal of that header means these functions have
no definition or declaration.

In most other configurations, <linux/acpi.h> continued to be included
through at least <linux/tboot.h> if CONFIG_INTEL_TXT was enabled, and
there were probably other implicit include paths too.

Add acpi.h explicitly so there is no more error, and so that we don't
continue to depend on these unreliable implicit include paths.

ebf435d3b5 IIO / Staging driver update for 5.15-rc1
Here is the big set of staging and IIO driver updates for 5.15-rc1.
 Also included in here are the counter driver subsystem updates as the
 IIO drivers needed them.
 
 Lots of churn in some staging drivers, we dropped the "old" rtl8188eu
 driver and replaced it with a newer version of the driver that had been
 maintained out-of-tree by Larry with the end goal of actually being able
 to get this driver out of staging eventually.  Despite that driver being
 "newer" the line count of this pull request is going up.
 
 Some drivers moved out of staging as well, which is always nice to see,
 that is why there are additions to the mfc and misc driver subsystems.
 All of these were acked by the various subsystem maintainers involved.
 
 But by far, as normal, it's coding style cleanups all over the
 drivers/staging/ tree in here.
 
 Full details of these changes are in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 problems.

[ Note: the r8188eu merge clashed with commit 89939e8906 ("staging:
  rtlwifi: use siocdevprivate") from the networking tree. When resolving
  the issue, I noted that the whole r8188eu rtw_android code is dead
  since commit ae7471cae0 ("staging: r8188eu: remove rtw_ioctl
  function").

  End result: the merge resolution was to throw all of that away,
  rather than do the mindless fixup to code that isn't actually
  reachable                                               - Linus ]

c6c3c5704b Driver core update for 5.15-rc1
Here is the big set of driver core patches for 5.15-rc1.
 
 These do change a number of different things across different
 subsystems, and because of that, there were 2 stable tags created that
 might have already come into your tree from different pulls that did the
 following
 	- changed the bus remove callback to return void
 	- sysfs iomem_get_mapping rework
 
 The latter one will cause a tiny merge issue with your tree, as there
 was a last-minute fix for this in 5.14 in your tree, but the fixup
 should be "obvious".  If you want me to provide a fixed merge for this,
 please let me know.
 
 Other than those two things, there's only a few small things in here:
 	- kernfs performance improvements for huge numbers of sysfs
 	  users at once
 	- tiny api cleanups
 	- other minor changes
 
 All of these have been in linux-next for a while with no reported
 problems, other than the before-mentioned merge issue.

efa916af13 - Add DM infrastructure for IMA-based remote attestion. These changes
are the basis for deploying DM-based storage in a "cloud" that must
   validate configurations end-users run to maintain trust. These DM
   changes allow supported DM targets' configurations to be measured
   via IMA. But the policy and enforcement (of which configurations are
   valid) is managed by something outside the kernel (e.g. Keylime).
 
 - Fix DM crypt scalability regression on systems with many cpus due to
   percpu_counter spinlock contention in crypt_page_alloc().
 
 - Use in_hardirq() instead of deprecated in_irq() in DM crypt.
 
 - Add event counters to DM writecache to allow users to further assess
   how the writecache is performing.
 
 - Various code cleanup in DM writecache's main IO mapping function.
