87199e4c24 drm/framebuffer: Format modifier for Intel Gen 12 render compression with Clear Color
Gen12 display can decompress surfaces compressed by render engine with
Clear Color, add a new modifier as the driver needs to know the surface
was compressed by render engine.

V2: Description changes as suggested by Rafael.
V3: Mention the Clear Color size of 64 bits in the comments(DK)
v4: Fix trailing whitespaces
v5: Explain Clear Color in the documentation.
v6: Documentation Nitpicks(Nanley)

0e0dc44800 drm/doc: demote old doc-comments in drm.h
Sphinx doesn't like old doc-comments in drm.h and generates warnings
like:

    ./include/uapi/drm/drm.h:87: warning: cannot understand function prototype: 'struct drm_clip_rect '
    ./include/uapi/drm/drm.h:97: warning: cannot understand function prototype: 'struct drm_drawable_info '
    ./include/uapi/drm/drm.h:105: warning: cannot understand function prototype: 'struct drm_tex_region '
    ...

Demote these to regular comments, because converting all of them is
quite a lot of work (also requires documenting all of the struct fields
for instance). Also many of these structures aren't really used by
modern user-space.

We can easily convert these remaining old comments to Sphinx style on a
one-by-one basis.

Pull GPIO updates from Linus Walleij:
 "This is the bulk of the GPIO changes for the v5.11 kernel cycle:

  Core changes:

   - Retired the old set-up function for GPIO IRQ chips. All chips now
     use the template struct gpio_irq_chip and pass that to the core to
     be set up alongside the gpio_chip. We can finally get rid of the
     old cruft.

   - Some refactoring and clean up of the core code.

   - Support edge event timestamps to be stamped using REALTIME (wall
     clock) timestamps. We have found solid use cases for this, so we
     support it.

  New drivers:

   - MStar MSC313 GPIO driver.

   - HiSilicon GPIO driver.

  Driver improvements:

   - The PCA953x driver now also supports the NXP PCAL9554B/C chips.

   - The mockup driver can now be probed from the device tree which is
     pretty useful for virtual prototyping of devices.

   - The Rcar driver now supports .get_multiple()

   - The MXC driver dropped some legacy and became a pure device tree
     client.

   - The Exar driver was moved over to the IDA interface for
     enumerating, and also switched over to using regmap for register
     access"

Pull cifs updates from Steve French:
 "The largest part are for support of the newer mount API which has been
  needed for cifs/smb3 mounts for a long time due to the new API's
  better handling of remount, and better error reporting. There are
  three additional small cleanup patches for this being tested, that are
  not included yet.

  This series also includes addition of support for the SMB3 witness
  protocol which can provide important notifications from the server to
  client on server address or export or network changes. This can be
  useful for example in order to be notified before the failure - when a
  server's IP address changes (in the future it will allow us to support
  server notifications of when a share is moved).

8c3b1ba0e7 drm/i915/gt: Track the overall awake/busy time
Since we wake the GT up before executing a request, and go to sleep as
soon as it is retired, the GT wake time not only represents how long the
device is powered up, but also provides a summary, albeit an overestimate,
of the device runtime (i.e. the rc0 time to compare against rc6 time).

v3: software-gt-awake-time and I915_PMU_SOFTWARE_GT_AWAKE_TIME

Pull f2fs updates from Jaegeuk Kim:
 "In this round, we've made more work into per-file compression support.

  For example, F2FS_IOC_GET | SET_COMPRESS_OPTION provides a way to
  change the algorithm or cluster size per file. F2FS_IOC_COMPRESS |
  DECOMPRESS_FILE provides a way to compress and decompress the existing
  normal files manually.

  There is also a new mount option, compress_mode=fs|user, which can
  control who compresses the data.

  Chao also added a checksum feature with a mount option so that
  we are able to detect any corrupted cluster.

  In addition, Daniel contributed casefolding with encryption patch,
  which will be used for Android devices.

  Summary:

  Enhancements:
   - add ioctls and mount option to manage per-file compression feature
   - support casefolding with encryption
   - support checksum for compressed cluster
   - avoid IO starvation by replacing mutex with rwsem
   - add sysfs, max_io_bytes, to control max bio size

  Bug fixes:
   - fix use-after-free issue when compression and fsverity are enabled
   - fix consistency corruption during fault injection test
   - fix data offset for lseek
   - get rid of buffer_head which has 32bits limit in fiemap
   - fix some bugs in multi-partitions support
   - fix nat entry count calculation in shrinker
   - fix some stat information

  And, we've refactored some logics and fix minor bugs as well"

with the _BITUL() macro which is already used in other macro definitions
in <linux/devlink.h>.

Pull io_uring updates from Jens Axboe:
 "Fairly light set of changes this time around, and mostly some bits
  that were pushed out to 5.11 instead of 5.10, fixes/cleanups, and a
  few features. In particular:

   - Cleanups around iovec import (David Laight, Pavel)

   - Add timeout support for io_uring_enter(2), which enables us to
     clean up liburing and avoid a timeout sqe submission in the
     completion path.

     The big win here is that it allows setups that split SQ and CQ
     handling into separate threads to avoid locking, as the CQ side
     will no longer submit when timeouts are needed when waiting for
     events (Hao Xu)

   - Add support for socket shutdown, and renameat/unlinkat.

   - SQPOLL cleanups and improvements (Xiaoguang Wang)

Pull close_range/openat2 updates from Christian Brauner:
 "This contains a fix for openat2() to make RESOLVE_BENEATH and
  RESOLVE_IN_ROOT mutually exclusive. It doesn't make sense to specify
  both at the same time. The openat2() selftests have been extended to
  verify that these two flags can't be specified together.

  This also adds the CLOSE_RANGE_CLOEXEC flag to close_range() which
  allows to mark a range of file descriptors as close-on-exec without
  actually closing them.

  This is useful in general but the use-case that triggered the patch is
  installing a seccomp profile in the calling task before exec. If the
  seccomp profile wants to block the close_range() syscall it obviously
  can't use it to close all fds before exec. If it calls close_range()
  before installing the seccomp profile it needs to take care not to
  close fds that it will still need before the exec meaning it would
  have to call close_range() multiple times on different ranges and then
  still fall back to closing fds one by one right before the exec.

  CLOSE_RANGE_CLOEXEC allows to solve this problem relying on the exec
  codepath to get rid of the unwanted fds. The close_range() tests have
  been expanded to verify that CLOSE_RANGE_CLOEXEC works"

 "We have a mix of all kinds of changes, feature updates, core stuff,
  performance improvements and lots of cleanups and preparatory changes.

  User visible:

   - export filesystem generation in sysfs

   - new features for mount option 'rescue':
       - what's currently supported is exported in sysfs
       - 'ignorebadroots'/'ibadroots' - continue even if some essential
         tree roots are not usable (extent, uuid, data reloc, device,
         csum, free space)
       - 'ignoredatacsums'/'idatacsums' - skip checksum verification on
         data
       - 'all' - now enables 'ignorebadroots' + 'ignoredatacsums' +
         'nologreplay'

   - export read mirror policy settings to sysfs, new policies will be
     added in the future

   - remove inode number cache feature (mount -o inode_cache), obsoleted
     in 5.9

  User visible fixes:

   - async discard scheduling fixes on high loads

   - update inode byte counter atomically so stat() does not report

   - free space tree fixes:
       - correctly report status of v2 after remount
       - clear v1 cache inodes when v2 is newly enabled after remount

  Core:

   - switch own tree lock implementation to standard rw semaphore:
       - one-level lock nesting is not required anymore, the last use of
         this was in free space that's now loaded asynchronously
       - own implementation of adaptive spinning before taking mutex has
         been part of rwsem
       - performance seems to be better in general, much better (+tens
         of percents) for some workloads
       - lockdep does not complain

   - finish direct IO conversion to iomap infrastructure, remove
     temporary workaround for DSYNC after iomap API updates

   - preparatory work to support data and metadata blocks smaller than
     page:
       - generalize code that assumes sectorsize == PAGE_SIZE, lots of
         refactoring
       - planned namely for 64K pages (eg. arm64, ppc64)
       - scrub read-only support

   - preparatory work for zoned allocation mode (SMR/ZBC/ZNS friendly):
       - disable incompatible features
       - round-robin superblock write

   - free space cache (v1) is loaded asynchronously, remove tree path
     recursion

   - slightly improved time tacking for transaction kthread wake ups

  Performance improvements (note that the numbers depend on load type or
  other features and weren't run on the same machine):

   - skip unnecessary work:
       - do not start readahead for csum tree when scrubbing non-data
         block groups
       - do not start and wait for delalloc on snapshot roots on
         transaction commit
       - fix race when defragmenting leads to unnecessary IO

   - dbench speedups (+throughput%/-max latency%):
       - skip unnecessary searches for xattrs when logging an inode
         (+10.8/-8.2)
       - stop incrementing log batch when joining log transaction (1-2)
       - unlock path before checking if extent is shared during nocow
         writeback (+5.0/-20.5), on fio load +9.7% throughput/-9.8%
         runtime
       - several tree log improvements, eg. removing unnecessary
         operations, fixing races that lead to additional work
         (+12.7/-8.2)

   - tree-checker error branches annotated with unlikely() (+3%
     throughput)

  Other:

   - cleanups

   - lockdep fixes

   - more btrfs_inode conversions

   - error variable cleanups"

37cd0575b8 userfaultfd: add UFFD_USER_MODE_ONLY
Patch series "Control over userfaultfd kernel-fault handling", v6.

This patch series is split from [1].  The other series enables SELinux
support for userfaultfd file descriptors so that its creation and movement
can be controlled.

It has been demonstrated on various occasions that suspending kernel code
execution for an arbitrary amount of time at any access to userspace
memory (copy_from_user()/copy_to_user()/...) can be exploited to change
the intended behavior of the kernel.  For instance, handling page faults
in kernel-mode using userfaultfd has been exploited in [2, 3].  Likewise,
FUSE, which is similar to userfaultfd in this respect, has been exploited
in [4, 5] for similar outcome.

This small patch series adds a new flag to userfaultfd(2) that allows
callers to give up the ability to handle kernel-mode faults with the
resulting UFFD file object.  It then adds a 'user-mode only' option to the
unprivileged_userfaultfd sysctl knob to require unprivileged callers to
use this new flag.

The purpose of this new interface is to decrease the chance of an
unprivileged userfaultfd user taking advantage of userfaultfd to enhance
security vulnerabilities by lengthening the race window in kernel code.

[5] https://bugs.chromium.org/p/project-zero/issues/detail?id=808

This patch (of 2):

userfaultfd handles page faults from both user and kernel code.  Add a new
UFFD_USER_MODE_ONLY flag for userfaultfd(2) that makes the resulting
userfaultfd object refuse to handle faults from kernel mode, treating
these faults as if SIGBUS were always raised, causing the kernel code to
fail with EFAULT.

A future patch adds a knob allowing administrators to give some processes
the ability to create userfaultfd file objects only if they pass
UFFD_USER_MODE_ONLY, reducing the likelihood that these processes will
exploit userfaultfd's ability to delay kernel page faults to open timing
windows for future exploits.

-> <linux/sysinfo.h>.

This indirect include causes on MUSL redefinition of struct sysinfo when

caaf95e0f2 vm_sockets: Add VMADDR_FLAG_TO_HOST vsock flag
Add VMADDR_FLAG_TO_HOST vsock flag that is used to setup a vsock
connection where all the packets are forwarded to the host.

Then, using this type of vsock channel, vsock communication between
sibling VMs can be built on top of it.

Changelog

v3 -> v4

* Update the "VMADDR_FLAG_TO_HOST" value, as the size of the field has
  been updated to 1 byte.

v2 -> v3

* Update comments to mention when the flag is set in the connect and
  listen paths.

v1 -> v2

* New patch in v2, it was split from the first patch in the series.
* Remove the default value for the vsock flags field.
* Update the naming for the vsock flag to "VMADDR_FLAG_TO_HOST".

dc8eeef73b vm_sockets: Add flags field in the vsock address data structure
vsock enables communication between virtual machines and the host they
are running on. With the multi transport support (guest->host and
host->guest), nested VMs can also use vsock channels for communication.

In addition to this, by default, all the vsock packets are forwarded to
the host, if no host->guest transport is loaded. This behavior can be
implicitly used for enabling vsock communication between sibling VMs.

Add a flags field in the vsock address data structure that can be used
to explicitly mark the vsock connection as being targeted for a certain
type of communication. This way, can distinguish between different use
cases such as nested VMs and sibling VMs.

This field can be set when initializing the vsock address variable used
for the connect() call.

Changelog

v3 -> v4

* Update the size of "svm_flags" field to be 1 byte instead of 2 bytes.

v2 -> v3

* Add "svm_flags" as a new field, not reusing "svm_reserved1".

v1 -> v2

* Update the field name to "svm_flags".
* Split the current patch in 2 patches.

Pull core entry/exit updates from Thomas Gleixner:
 "A set of updates for entry/exit handling:

   - More generalization of entry/exit functionality

   - The consolidation work to reclaim TIF flags on x86 and also for
     non-x86 specific TIF flags which are solely relevant for syscall
     related work and have been moved into their own storage space. The
     x86 specific part had to be merged in to avoid a major conflict.

   - The TIF_NOTIFY_SIGNAL work which replaces the inefficient signal
     delivery mode of task work and results in an impressive performance
     improvement for io_uring. The non-x86 consolidation of this is
     going to come seperate via Jens.

   - The selective syscall redirection facility which provides a clean
     and efficient way to support the non-Linux syscalls of WINE by
     catching them at syscall entry and redirecting them to the user
     space emulation. This can be utilized for other purposes as well
     and has been designed carefully to avoid overhead for the regular
     fastpath. This includes the core changes and the x86 support code.

   - Simplification of the context tracking entry/exit handling for the
     users of the generic entry code which guarantee the proper ordering
     and protection.

   - Preparatory changes to make the generic entry code accomodate S390
     specific requirements which are mostly related to their syscall
     restart mechanism"
