Linus Torvalds 71a7507afb Driver Core changes for 6.2-rc1
Here is the set of driver core and kernfs changes for 6.2-rc1.
 
 The "big" change in here is the addition of a new macro,
 container_of_const() that will preserve the "const-ness" of a pointer
 passed into it.
 
 The "problem" of the current container_of() macro is that if you pass in
 a "const *", out of it can comes a non-const pointer unless you
 specifically ask for it.  For many usages, we want to preserve the
 "const" attribute by using the same call.  For a specific example, this
 series changes the kobj_to_dev() macro to use it, allowing it to be used
 no matter what the const value is.  This prevents every subsystem from
 having to declare 2 different individual macros (i.e.
 kobj_const_to_dev() and kobj_to_dev()) and having the compiler enforce
 the const value at build time, which having 2 macros would not do
 either.
 
 The driver for all of this have been discussions with the Rust kernel
 developers as to how to properly mark driver core, and kobject, objects
 as being "non-mutable".  The changes to the kobject and driver core in
 this pull request are the result of that, as there are lots of paths
 where kobjects and device pointers are not modified at all, so marking
 them as "const" allows the compiler to enforce this.
 
 So, a nice side affect of the Rust development effort has been already
 to clean up the driver core code to be more obvious about object rules.
 
 All of this has been bike-shedded in quite a lot of detail on lkml with
 different names and implementations resulting in the tiny version we
 have in here, much better than my original proposal.  Lots of subsystem
 maintainers have acked the changes as well.
 
 Other than this change, included in here are smaller stuff like:
   - kernfs fixes and updates to handle lock contention better
   - vmlinux.lds.h fixes and updates
   - sysfs and debugfs documentation updates
   - device property updates
 
 All of these have been in the linux-next tree for quite a while with no
 problems, OTHER than some merge issues with other trees that should be
 obvious when you hit them (block tree deletes a driver that this tree
 modifies, iommufd tree modifies code that this tree also touches).  If
 there are merge problems with these trees, please let me know.

  - fastrpc driver updates
  - iio new drivers and updates
  - habanalabs driver updates for new hardware and features
  - slimbus driver updates
  - speakup module parameters added to aid in boot time configuration
  - i2c probe_new conversions for lots of different drivers

   - minor thunderbolt driver changes and tweaks
   - chipidea driver updates
   - usual set of typec driver features and hardware support added
   - musb minor driver fixes
   - fotg210 driver fixes, bringing that hardware back from the "dead"
   - minor dwc3 driver updates
   - addition, and then removal, of a list.h helper function for many USB
     and other subsystem drivers, that ended up breaking the build.  That
     will come back for 6.3-rc1, it missed this merge window.
   - usual xhci updates and enhancements
   - usb-serial driver updates and support for new devices
   - other minor USB driver updates

Linus Torvalds 041fae9c10 f2fs-for-6.2-rc1
In this round, we've added two features: 1) F2FS_IOC_START_ATOMIC_REPLACE and
 2) per-block age-based extent cache. 1) is a variant of the previous atomic
 write feature which guarantees a per-file atomicity. It would be more efficient
 than AtomicFile implementation in Android framework. 2) implements another type
 of extent cache in memory which keeps the per-block age in a file, so that block
 allocator could split the hot and cold data blocks more accurately.
 
 Enhancement:
  - introduce F2FS_IOC_START_ATOMIC_REPLACE
  - refactor extent_cache to add a new per-block-age-based extent cache support
  - introduce discard_urgent_util, gc_mode, max_ordered_discard sysfs knobs
  - add proc entry to show discard_plist info
  - optimize iteration over sparse directories
  - add barrier mount option
 
 Bug fix
  - avoid victim selection from previous victim section
  - fix to enable compress for newly created file if extension matches
  - set zstd compress level correctly
  - initialize locks early in f2fs_fill_super() to fix bugs reported by syzbot
  - correct i_size change for atomic writes
  - allow to read node block after shutdown
  - allow to set compression for inlined file
  - fix gc mode when gc_urgent_high_remaining is 1
  - should put a page when checking the summary info
 
 Minor fixes and various clean-ups in GC, discard, debugfs, sysfs, and doc.

Linus Torvalds 48ea09cdda hardening updates for v6.2-rc1
- Convert flexible array members, fix -Wstringop-overflow warnings,
   and fix KCFI function type mismatches that went ignored by
   maintainers (Gustavo A. R. Silva, Nathan Chancellor, Kees Cook).
 
 - Remove the remaining side-effect users of ksize() by converting
   dma-buf, btrfs, and coredump to using kmalloc_size_roundup(),
   add more __alloc_size attributes, and introduce full testing
   of all allocator functions. Finally remove the ksize() side-effect
   so that each allocation-aware checker can finally behave without
   exceptions.
 
 - Introduce oops_limit (default 10,000) and warn_limit (default off)
   to provide greater granularity of control for panic_on_oops and
   panic_on_warn (Jann Horn, Kees Cook).
 
 - Introduce overflows_type() and castable_to_type() helpers for
   cleaner overflow checking.
 
 - Improve code generation for strscpy() and update str*() kern-doc.
 
 - Convert strscpy and sigphash tests to KUnit, and expand memcpy
   tests.
 
 - Always use a non-NULL argument for prepare_kernel_cred().
 
 - Disable structleak plugin in FORTIFY KUnit test (Anders Roxell).
 
 - Adjust orphan linker section checking to respect CONFIG_WERROR
   (Xin Li).
 
 - Make sure siginfo is cleared for forced SIGKILL (haifeng.xu).
 
 - Fix um vs FORTIFY warnings for always-NULL arguments.

Merge tag 'hardening-v6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull kernel hardening updates from Kees Cook:

 - Convert flexible array members, fix -Wstringop-overflow warnings, and
   fix KCFI function type mismatches that went ignored by maintainers
   (Gustavo A. R. Silva, Nathan Chancellor, Kees Cook)

 - Remove the remaining side-effect users of ksize() by converting
   dma-buf, btrfs, and coredump to using kmalloc_size_roundup(), add
   more __alloc_size attributes, and introduce full testing of all
   allocator functions. Finally remove the ksize() side-effect so that
   each allocation-aware checker can finally behave without exceptions

 - Introduce oops_limit (default 10,000) and warn_limit (default off) to
   provide greater granularity of control for panic_on_oops and
   panic_on_warn (Jann Horn, Kees Cook)

 - Introduce overflows_type() and castable_to_type() helpers for cleaner
   overflow checking

 - Improve code generation for strscpy() and update str*() kern-doc

 - Convert strscpy and sigphash tests to KUnit, and expand memcpy tests

 - Always use a non-NULL argument for prepare_kernel_cred()

 - Disable structleak plugin in FORTIFY KUnit test (Anders Roxell)

 - Adjust orphan linker section checking to respect CONFIG_WERROR (Xin
   Li)

 - Make sure siginfo is cleared for forced SIGKILL (haifeng.xu)

 - Fix um vs FORTIFY warnings for always-NULL arguments

Pull drm updates from Dave Airlie:
 "The biggest highlight is that the accel subsystem framework is merged.
  Hopefully for 6.3 we will be able to line up a driver to use it.

  In drivers land, i915 enables DG2 support by default now, and nouveau
  has a big stability refactoring and initial ampere support, AMD
  includes new hw IP support and should build on ARM again. There is
  also an ofdrm driver to take over offb on platforms it's used.

  Stuff outside my tree, the dma-buf patches hit a few places, the vc4
  firmware changes also do, and i915 has some interactions with MEI for
  discrete GPUs. I think all of those should have been acked/reviewed by
  relevant parties.

Linus Torvalds add7695957 Perf events updates for v6.2:
- Thoroughly rewrite the data structures that implement perf task context handling,
    with the goal of fixing various quirks and unfeatures both in already merged,
    and in upcoming proposed code.
 
    The old data structure is the per task and per cpu perf_event_contexts:
 
          task_struct::perf_events_ctxp[] <-> perf_event_context <-> perf_cpu_context
               ^                                 |    ^     |           ^
               `---------------------------------'    |     `--> pmu ---'
                                                      v           ^
                                                 perf_event ------'
 
    In this new design this is replaced with a single task context and
    a single CPU context, plus intermediate data-structures:
 
          task_struct::perf_event_ctxp -> perf_event_context <- perf_cpu_context
               ^                           |   ^ ^
               `---------------------------'   | |
                                               | |    perf_cpu_pmu_context <--.
                                               | `----.    ^                  |
                                               |      |    |                  |
                                               |      v    v                  |
                                               | ,--> perf_event_pmu_context  |
                                               | |                            |
                                               | |                            |
                                               v v                            |
                                          perf_event ---> pmu ----------------'
 
    [ See commit bd27568117 for more details. ]
 
    This rewrite was developed by Peter Zijlstra and Ravi Bangoria.
 
  - Optimize perf_tp_event()
 
  - Update the Intel uncore PMU driver, extending it with UPI topology discovery
    on various hardware models.
 
  - Misc fixes & cleanups

Jaegeuk Kim 71644dff48 f2fs: add block_age-based extent cache
This patch introduces a runtime hot/cold data separation method
for f2fs, in order to improve the accuracy for data temperature
classification, reduce the garbage collection overhead after
long-term data updates.

Enhanced hot/cold data separation can record data block update
frequency as "age" of the extent per inode, and take use of the age
info to indicate better temperature type for data block allocation:
 - It records total data blocks allocated since mount;
 - When file extent has been updated, it calculate the count of data
blocks allocated since last update as the age of the extent;
 - Before the data block allocated, it searches for the age info and
chooses the suitable segment for allocation.

Test and result:
 - Prepare: create about 30000 files
  * 3% for cold files (with cold file extension like .apk, from 3M to 10M)
  * 50% for warm files (with random file extension like .FcDxq, from 1K
to 4M)
  * 47% for hot files (with hot file extension like .db, from 1K to 256K)
 - create(5%)/random update(90%)/delete(5%) the files
  * total write amount is about 70G
  * fsync will be called for .db files, and buffered write will be used
for other files

The storage of test device is large enough(128G) so that it will not
switch to SSR mode during the test.

Benefit: dirty segment count increment reduce about 14%
 - before: Dirty +21110
 - after:  Dirty +18286

Pull cxl updates from Dan Williams:
 "Compute Express Link (CXL) updates for 6.2.

  While it may seem backwards, the CXL update this time around includes
  some focus on CXL 1.x enabling where the work to date had been with
  CXL 2.0 (VH topologies) in mind.

  First generation CXL can mostly be supported via BIOS, similar to DDR,
  however it became clear there are use cases for OS native CXL error
  handling and some CXL 3.0 endpoint features can be deployed on CXL 1.x
  hosts (Restricted CXL Host (RCH) topologies). So, this update brings
  RCH topologies into the Linux CXL device model.

  In support of the ongoing CXL 2.0+ enabling two new core kernel
  facilities are added.

  One is the ability for the kernel to flag collisions between userspace
  access to PCI configuration registers and kernel accesses. This is
  brought on by the PCIe Data-Object-Exchange (DOE) facility, a hardware
  mailbox over config-cycles.

  The other is a cpu_cache_invalidate_memregion() API that maps to
  wbinvd_on_all_cpus() on x86. To prevent abuse it is disabled in guest
  VMs and architectures that do not support it yet. The CXL paths that
  need it, dynamic memory region creation and security commands (erase /
  unlock), are disabled when it is not present.

  As for the CXL 2.0+ this cycle the subsystem gains support Persistent
  Memory Security commands, error handling in response to PCIe AER
  notifications, and support for the "XOR" host bridge interleave
  algorithm.

  Summary:

   - Add the cpu_cache_invalidate_memregion() API for cache flushing in
     response to physical memory reconfiguration, or memory-side data
     invalidation from operations like secure erase or memory-device
     unlock.

   - Add a facility for the kernel to warn about collisions between
     kernel and userspace access to PCI configuration registers

   - Add support for Restricted CXL Host (RCH) topologies (formerly CXL
     1.1)

   - Add handling and reporting of CXL errors reported via the PCIe AER
     mechanism

   - Add support for CXL Persistent Memory Security commands

   - Add support for the "XOR" algorithm for CXL host bridge interleave

   - Rework / simplify CXL to NVDIMM interactions

   - Miscellaneous cleanups and fixes"

Daniel Scally 81c25247a2 usb: gadget: uvc: Rename bmInterfaceFlags -> bmInterlaceFlags
In the specification documents for the Uncompressed and MJPEG USB
Video Payloads, the field name is bmInterlaceFlags - it has been
misnamed within the kernel.

Although renaming the field does break the kernel's interface to
userspace it should be low-risk in this instance. The field is read
only and hardcoded to 0, so there was never any value in anyone
reading it. A search of the uvc-gadget application and all the
forks that I could find for it did not reveal any users either.

Dave Jiang bd429e5355 cxl/pmem: add id attribute to CXL based nvdimm
Add an id group attribute for CXL based nvdimm object. The addition allows
ndctl to display the "unique id" for the nvdimm. The serial number for the
CXL memory device will be used for this id.

[
  {
      "dev":"nmem10",
      "id":"0x4",
      "security":"disabled"
  },
]

The id attribute is needed by the ndctl security key management to setup a
keyblob with a unique file name tied to the mem device.

Greg Kroah-Hartman 56d784d177 1st set of IIO new device support, feature and cleanup for 6.2 (take2)
We have finally managed to take the mlock mutex entirely private so as
 to avoid it being used for multiple purposes.  Now it is just used to
 protect device mode transitions (typically to and from buffered capture).
 
 Includes merge of an immutable i2c branch to get the new
 i2c_client_get_device_id() (thanks to Wolfram for providing the branch).
 
 Based on rc3 to pick up some precursor fixes from early in the cycle and
 avoid an unnecessarily messy history.

    of the correct type.
  - Last transitions of drivers to local locks rather than missuses of mlock.
  - Add an iio_device_claim_buffer_mode() callback to avoid a race in the
    max30100 driver without directly using mlock.
  - Move mlock to the opaque IIO device structure to prevent misuse.
  - Add missing spi_device_id tables to support auto loading of modules.
  - Update some ADI maintainers in DT bindings.

David E. Box a96f1b9c48 platform/x86/intel/sdsi: Add meter certificate support
Add support for reading the meter certificate from Intel On Demand
hardware.  The meter certificate [1] is used to access the utilization
metrics of enabled features in support of the Intel On Demand consumption
model. Similar to the state certificate, the meter certificate is read by
mailbox command.

While making similar changes also use the BIN_ATTR_ADMIN_RO helper to
create the 'registers' sysfs file.

Armin Wolf a77272c160 platform/x86: dell: Add new dell-wmi-ddv driver
The dell-wmi-ddv driver adds support for reading
the current temperature and ePPID of ACPI batteries
on supported Dell machines.

Since the WMI interface used by this driver does not
do any input validation and thus cannot be used for probing,
the driver depends on the ACPI battery extension machanism
to discover batteries.

The driver also supports a debugfs interface for retrieving
buffers containing fan and thermal sensor information.
Since the meaing of the content of those buffers is currently
unknown, the interface is meant for reverse-engineering and
will likely be replaced with an hwmon interface once the
meaning has been understood.

The driver was tested on a Dell Inspiron 3505.

Thomas Weißschuh d3d76fbde1 kernel/ksysfs.c: export kernel cpu byteorder
Certain files in procfs are formatted in byteorder-dependent formats.
For example the IP addresses in /proc/net/udp.

When using emulation like qemu-user, applications are not guaranteed to
be using the same byteorder as the kernel.
Therefore the kernel needs to provide a way for applications to discover
the byteorder used in API-filesystems.
Using systemcalls is not enough because these are intercepted and
translated by the emulation.

Also this makes it easier for non-compiled applications like
shellscripts to discover the byteorder.
