1e4ce418b1 HID: betop: fix slab-out-of-bounds Write in betop_probe 
Syzbot reported slab-out-of-bounds Write bug in hid-betopff driver.
The problem is the driver assumes the device must have an input report but
some malicious devices violate this assumption.

So this patch checks hid_device's input is non empty before it's been used.

75d6e7d9ce Nothing changed in the clk framework core this time around. We did get 
some updates to the basic clk types to use determine_rate for the
 divider type and add a power of two fractional divider flag though.
 Otherwise, this is a collection of clk driver updates. More than half
 the diffstat is in the Qualcomm clk driver where we add a bunch of data
 to describe clks on various SoCs and fix bugs. The other big new thing
 in here is the Mediatek MT8192 clk driver. That's been under review for
 a while and it's nice to see that it's finally upstream.
 
 Beyond that it's the usual set of minor fixes and tweaks to clk drivers.
 There are some non-clk driver bits in here which have all been acked by
 the respective maintainers.
 
 New Drivers:
  - Support video, gpu, display clks on qcom sc7280 SoCs
  - GCC clks on qcom MSM8953, SM4250/6115, and SM6350 SoCs
  - Multimedia clks (MMCC) on qcom MSM8994/MSM8992
  - RPMh clks on qcom SM6350 SoCs
  - Support for Mediatek MT8192 SoCs
  - Add display (DU and DSI) clocks on Renesas R-Car V3U
  - Add I2C, DMAC, USB, sound (SSIF-2), GPIO, CANFD, and ADC clocks and
    resets on Renesas RZ/G2L
 
 Updates:
  - Support the SD/OE pin on IDT VersaClock 5 and 6 clock generators
  - Add power of two flag to fractional divider clk type
  - Migrate some clk drivers to clk_divider_ops.determine_rate
  - Migrate to clk_parent_data in gcc-sdm660
  - Fix CLKOUT clocks on i.MX8MM and i.MX8MN by using imx_clk_hw_mux2
  - Switch from .round_rate to .determine_rate in clk-divider-gate
  - Fix clock tree update for TF-A controlled clocks for all i.MX8M
  - Add missing M7 core clock for i.MX8MN
  - YAML conversion of rk3399 clock controller binding
  - Removal of GRF dependency for the rk3328/rk3036 pll types
  - Drop CLK_IS_CRITICAL flag from Tegra fuse clk
  - Make CLK_R9A06G032 Kconfig symbol invisible
  - Convert various DT bindings to YAML

7661809d49 mm: don't allow oversized kvmalloc() calls 
'kvmalloc()' is a convenience function for people who want to do a
kmalloc() but fall back on vmalloc() if there aren't enough physically
contiguous pages, or if the allocation is larger than what kmalloc()
supports.

However, let's make sure it doesn't get _too_ easy to do crazy things
with it.  In particular, don't allow big allocations that could be due
to integer overflow or underflow.  So make sure the allocation size fits
in an 'int', to protect against trivial integer conversion issues.

Pull erofs updates from Gao Xiang:
 "In this cycle, direct I/O and fsdax support for uncompressed files are
  now added in order to avoid double-caching for loop device and VM
  container use cases. All uncompressed cases are now turned into iomap
  infrastructure, which looks much simpler and cleaner.

  In addition, fiemap support is added for both (un)compressed files by
  using iomap infrastructure as well so end users can easily get file
  distribution. We've also added chunk-based uncompressed files support
  for data deduplication as the next step of VM container use cases.

  Summary:

   - support direct I/O for all uncompressed files

   - Add a cookie debug ID that can be used in tracepoints instead of a
     pointer and cache it in the netfs_cache_resources struct rather
     than in the netfs_read_request struct to make it more available.

   - Use file_inode() in cachefiles rather than dereferencing
     file->f_inode directly.

   - Provide a procfile to display fscache cookies.

   - Remove the fscache and cachefiles histogram procfiles.

   - Remove the fscache object list procfile.

   - Avoid using %p in fscache and cachefiles as the value is hashed and
     not comparable to the register dump in an oops trace.

   - Fix the cookie hash function to actually achieve useful dispersion.

   - Fix fscache_cookie_put() so that it doesn't dereference the cookie
     pointer in the tracepoint after the refcount has been decremented

90c90cda05 New code for 5.15: 
- Fix a potential log livelock on busy filesystems when there's so much
    work going on that we can't finish a quotaoff before filling up the log
    by removing the ability to disable quota accounting.
  - Introduce the ability to use per-CPU data structures in XFS so that
    we can do a better job of maintaining CPU locality for certain
    operations.
  - Defer inode inactivation work to per-CPU lists, which will help us
    batch that processing.  Deletions of large sparse files will *appear*
    to run faster, but all that means is that we've moved the work to the
    backend.
  - Drop the EXPERIMENTAL warnings from the y2038+ support and the inode
    btree counters, since it's been nearly a year and no complaints have
    come in.
  - Remove more of our bespoke kmem* variants in favor of using the
    standard Linux calls.
  - Prepare for the addition of log incompat features in upcoming cycles
    by actually adding code to support this.
  - Small cleanups of the xattr code in preparation for landing support
    for full logging of extended attribute updates in a future cycle.
  - Replace the various log shutdown state and flag code all over xfs
    with a single atomic bit flag.
  - Fix a serious log recovery bug where log item replay can be skipped
    based on the start lsn of a transaction even though the transaction
    commit lsn is the key data point for that by enforcing start lsns to
    appear in the log in the same order as commit lsns.
  - Enable pipelining in the code that pushes log items to disk.
  - Drop ->writepage.
  - Fix some bugs in GETFSMAP where the last fsmap record reported for a
    device could extend beyond the end of the device, and a separate bug
    where query keys for one device could be applied to another.
  - Don't let GETFSMAP query functions edit their input parameters.
  - Small cleanups to the scrub code's handling of perag structures.
  - Small cleanups to the incore inode tree walk code.
  - Constify btree function parameters that aren't changed, so that there
    will never again be confusion about range query functions changing
    their input parameters.
  - Standardize the format and names of tracepoint data attributes.
  - Clean up all the mount state and feature flags to use wrapped bitset
    functions instead of inconsistently open-coded flag checks.
  - Fix some confusion between xfs_buf hash table key variable vs. block
    number.
  - Fix a mis-interaction with iomap where we reported shared delalloc
    cow fork extents to iomap, which would cause the iomap unshare
    operation to return IO errors unnecessarily.
  - Fix DONTCACHE behavior.

Merge tag 'xfs-5.15-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Darrick Wong:
 "There's a lot in this cycle.

  Starting with bug fixes: To avoid livelocks between the logging code
  and the quota code, we've disabled the ability of quotaoff to turn off
  quota accounting. (Admins can still disable quota enforcement, but
  truly turning off accounting requires a remount.) We've tried to do
  this in a careful enough way that there shouldn't be any user visible
  effects aside from quotaoff no longer randomly hanging the system.

  We've also fixed some bugs in runtime log behavior that could trip up
  log recovery if (otherwise unrelated) transactions manage to start and
  commit concurrently; some bugs in the GETFSMAP ioctl where we would
  incorrectly restrict the range of records output if the two xfs
  devices are of different sizes; a bug that resulted in fallocate
  funshare failing unnecessarily; and broken behavior in the xfs inode
  cache when DONTCACHE is in play.

  As for new features: we now batch inode inactivations in percpu
  background threads, which sharply decreases frontend thread wait time
  when performing file deletions and should improve overall directory
  tree deletion times. This eliminates both the problem where closing an
  unlinked file (especially on a frozen fs) can stall for a long time,
  and should also ease complaints about direct reclaim bogging down on
  unlinked file cleanup.

  Starting with this release, we've enabled pipelining of the XFS log.
  On workloads with high rates of metadata updates to different shards
  of the filesystem, multiple threads can be used to format committed
  log updates into log checkpoints.

  Lastly, with this release, two new features have graduated to
  supported status: inode btree counters (for faster mounts), and
  support for dates beyond Y2038. Expect these to be enabled by default
  in a future release of xfsprogs.

  Summary:

   - Fix a potential log livelock on busy filesystems when there's so
     much work going on that we can't finish a quotaoff before filling
     up the log by removing the ability to disable quota accounting.

   - Introduce the ability to use per-CPU data structures in XFS so that
     we can do a better job of maintaining CPU locality for certain
     operations.

   - Defer inode inactivation work to per-CPU lists, which will help us
     batch that processing. Deletions of large sparse files will
     *appear* to run faster, but all that means is that we've moved the
     work to the backend.

   - Drop the EXPERIMENTAL warnings from the y2038+ support and the
     inode btree counters, since it's been nearly a year and no
     complaints have come in.

   - Remove more of our bespoke kmem* variants in favor of using the
     standard Linux calls.

   - Prepare for the addition of log incompat features in upcoming
     cycles by actually adding code to support this.

   - Small cleanups of the xattr code in preparation for landing support
     for full logging of extended attribute updates in a future cycle.

   - Replace the various log shutdown state and flag code all over xfs
     with a single atomic bit flag.

Pull printk updates from Petr Mladek:

 - Optionally, provide an index of possible printk messages via
   <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.

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

Merge tag 'soc-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC updates from Arnd Bergmann:
 "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().

- Support for 32-bit tasks on asymmetric AArch32 systems (on top of the
   scheduler changes merged via the tip tree).
 
 - More entry.S clean-ups and conversion to C.
 
 - MTE updates: allow a preferred tag checking mode to be set per CPU
   (the overhead of synchronous mode is smaller for some CPUs than
   others); optimisations for kernel entry/exit path; optionally disable

 - Kselftest improvements for SVE and signal handling, PtrAuth.
 
 - Fix unlikely race where a TLBI could use stale ASID on an ASID
   roll-over (found by inspection).
 
 - Miscellaneous fixes: disable trapping of PMSNEVFR_EL1 to higher
   exception levels; drop unnecessary sigdelsetmask() call in the
   signal32 handling; remove BUG_ON when failing to allocate SVE state
   (just signal the process); SYM_CODE annotations.
 
 - Other trivial clean-ups: use macros instead of magic numbers, remove

bcfeebbff3 Merge branch 'exit-cleanups-for-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace 
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"

Pull siginfo si_trapno updates from Eric Biederman:
 "The full set of si_trapno changes was not appropriate as a fix for the
  newly added SIGTRAP TRAP_PERF, and so I postponed the rest of the
  related cleanups.

  This is the rest of the cleanups for si_trapno that reduces it from
  being a really weird arch special case that is expect to be always
  present (but isn't) on the architectures that support it to being yet
  another field in the _sigfault union of struct siginfo.

  The changes have been reviewed and marinated in linux-next. With the
  removal of this awkward special case new code (like SIGTRAP TRAP_PERF)
  that works across architectures should be easier to write and
  maintain"
