cc18cc5e82 io_uring: mem-account pbuf buckets
Potentially, someone may create as many pbuf bucket as there are indexes
in an xarray without any other restrictions bounding our memory usage,
put memory needed for the buckets under memory accounting.

f482aa9865 audit, io_uring, io-wq: Fix memory leak in io_sq_thread() and io_wqe_worker()
Currently @audit_context is allocated twice for io_uring workers:

  1. copy_process() calls audit_alloc();
  2. io_sq_thread() or io_wqe_worker() calls audit_alloc_kernel() (which
     is effectively audit_alloc()) and overwrites @audit_context,
     causing:

Then,

  3. io_sq_thread() or io_wqe_worker() frees @audit_context using
     audit_free();
  4. do_exit() eventually calls audit_free() again, which is okay
     because audit_free() does a NULL check.

As suggested by Paul Moore, fix it by deleting audit_alloc_kernel() and
redundant audit_free() calls.

e2b5421007 flexible-array transformations in UAPI for 6.0-rc1
Hi Linus,
 
 Please, pull the following treewide patch that replaces zero-length arrays
 with flexible-array members in UAPI. This patch has been baking in
 linux-next for 5 weeks now.
 
 -fstrict-flex-arrays=3 is coming and we need to land these changes
 to prevent issues like these in the short future:
 
 ../fs/minix/dir.c:337:3: warning: 'strcpy' will always overflow; destination buffer has size 0,
 but the source string has length 2 (including NUL byte) [-Wfortify-source]
 		strcpy(de3->name, ".");
 		^
 
 Since these are all [0] to [] changes, the risk to UAPI is nearly zero. If
 this breaks anything, we can use a union with a new member name.
 
 Link: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101836
 
 Thanks

665fe72a7d linux-kselftest-kunit-5.20-rc1
This KUnit update for Linux 5.20-rc1 consists of several fixes and an
 important feature to discourage running KUnit tests on production
 systems. Running tests on a production system could leave the system
 in a bad state. This new feature adds:
 
 - adds a new taint type, TAINT_TEST to signal that a test has been run.
   This should discourage people from running these tests on production
   systems, and to make it easier to tell if tests have been run
   accidentally (by loading the wrong configuration, etc.)
 
 - several documentation and tool enhancements and fixes.

 nocb.2022.07.19a: Callback-offload updates, perhaps most notably a new
 	RCU_NOCB_CPU_DEFAULT_ALL Kconfig option that causes all CPUs to
 	be offloaded at boot time, regardless of kernel boot parameters.
 	This is useful to battery-powered systems such as ChromeOS
 	and Android.  In addition, a new RCU_NOCB_CPU_CB_BOOST kernel
 	boot parameter prevents offloaded callbacks from interfering
 	with real-time workloads and with energy-efficiency mechanisms.

 	periods.
 
 rcu-tasks.2022.06.21a: Tasks RCU updates, perhaps most notably reducing
 	the CPU overhead of RCU tasks trace grace periods by more than
 	a factor of two on a system with 15,000 tasks.	The reduction
 	is expected to increase with the number of tasks, so it seems
 	reasonable to hypothesize that a system with 150,000 tasks might
 	see a 20-fold reduction in CPU overhead.
 
 torture.2022.06.21a: Torture-test updates.
 
 ctxt.2022.07.05a: Updates that merge RCU's dyntick-idle tracking into
 	context tracking, thus reducing the overhead of transitioning to
 	kernel mode from either idle or nohz_full userspace execution
 	for kernels that track context independently of RCU.  This is
 	expected to be helpful primarily for kernels built with
 	CONFIG_NO_HZ_FULL=y.

Merge tag 'rcu.2022.07.26a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu

Pull RCU updates from Paul McKenney:

 - Documentation updates

 - Miscellaneous fixes

 - Callback-offload updates, perhaps most notably a new
   RCU_NOCB_CPU_DEFAULT_ALL Kconfig option that causes all CPUs to be
   offloaded at boot time, regardless of kernel boot parameters.

   This is useful to battery-powered systems such as ChromeOS and
   Android. In addition, a new RCU_NOCB_CPU_CB_BOOST kernel boot
   parameter prevents offloaded callbacks from interfering with
   real-time workloads and with energy-efficiency mechanisms

 - Polled grace-period updates, perhaps most notably making these APIs
   account for both normal and expedited grace periods

 - Tasks RCU updates, perhaps most notably reducing the CPU overhead of
   RCU tasks trace grace periods by more than a factor of two on a
   system with 15,000 tasks.

   The reduction is expected to increase with the number of tasks, so it
   seems reasonable to hypothesize that a system with 150,000 tasks
   might see a 20-fold reduction in CPU overhead

 - Torture-test updates

 - Updates that merge RCU's dyntick-idle tracking into context tracking,
   thus reducing the overhead of transitioning to kernel mode from
   either idle or nohz_full userspace execution for kernels that track
   context independently of RCU.

   This is expected to be helpful primarily for kernels built with
   CONFIG_NO_HZ_FULL=y

Merge tag 'random-6.0-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random

Pull random number generator updates from Jason Donenfeld:
 "Though there's been a decent amount of RNG-related development during
  this last cycle, not all of it is coming through this tree, as this
  cycle saw a shift toward tackling early boot time seeding issues,
  which took place in other trees as well.

  Here's a summary of the various patches:

   - The CONFIG_ARCH_RANDOM .config option and the "nordrand" boot
     option have been removed, as they overlapped with the more widely
     supported and more sensible options, CONFIG_RANDOM_TRUST_CPU and
     "random.trust_cpu". This change allowed simplifying a bit of arch
     code.

   - x86's RDRAND boot time test has been made a bit more robust, with
     RDRAND disabled if it's clearly producing bogus results. This would
     be a tip.git commit, technically, but I took it through random.git
     to avoid a large merge conflict.

   - The RNG has long since mixed in a timestamp very early in boot, on
     the premise that a computer that does the same things, but does so
     starting at different points in wall time, could be made to still
     produce a different RNG state. Unfortunately, the clock isn't set
     early in boot on all systems, so now we mix in that timestamp when
     the time is actually set.

   - User Mode Linux now uses the host OS's getrandom() syscall to
     generate a bootloader RNG seed and later on treats getrandom() as
     the platform's RDRAND-like faculty.

   - The arch_get_random_{seed_,}_long() family of functions is now
     arch_get_random_{seed_,}_longs(), which enables certain platforms,
     such as s390, to exploit considerable performance advantages from
     requesting multiple CPU random numbers at once, while at the same
     time compiling down to the same code as before on platforms like
     x86.

   - A small cleanup changing a cmpxchg() into a try_cmpxchg(), from
     Uros.

   - A comment spelling fix"

Merge tag 'selinux-pr-20220801' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux

Pull selinux updates from Paul Moore:
 "A relatively small set of patches for SELinux this time, eight patches
  in total with really only one significant change.

  The highlights are:

   - Add support for proper labeling of memfd_secret anonymous inodes.

     This will allow LSMs that implement the anonymous inode hooks to
     apply security policy to memfd_secret() fds.

   - Various small improvements to memory management: fixed leaks, freed
     memory when needed, boundary checks.

   - Hardened the selinux_audit_data struct with __randomize_layout.

   - A minor documentation tweak to fix a formatting/style issue"

  The core network changes to support this is in a stable branch from
  Jakub that both io_uring and net-next has pulled in, and the io_uring
  changes are layered on top of that.

Pull io_uring buffered writes support from Jens Axboe:
 "This contains support for buffered writes, specifically for XFS. btrfs
  is in progress, will be coming in the next release.

  io_uring does support buffered writes on any file type, but since the
  buffered write path just always -EAGAIN (or -EOPNOTSUPP) any attempt
  to do so if IOCB_NOWAIT is set, any buffered write will effectively be
  handled by io-wq offload. This isn't very efficient, and we even have
  specific code in io-wq to serialize buffered writes to the same inode
  to avoid further inefficiencies with thread offload.

  This is particularly sad since most buffered writes don't block, they
  simply copy data to a page and dirty it. With this pull request, we
  can handle buffered writes a lot more effiently.

  If balance_dirty_pages() needs to block, we back off on writes as
  indicated.

  This improves buffered write support by 2-3x.

  Jan Kara helped with the mm bits for this, and Stefan handled the
  fs/iomap/xfs/io_uring parts of it"

Pull io_uring updates from Jens Axboe:

 - As per (valid) complaint in the last merge window, fs/io_uring.c has
   grown quite large these days. io_uring isn't really tied to fs
   either, as it supports a wide variety of functionality outside of
   that.

   Move the code to io_uring/ and split it into files that either
   implement a specific request type, and split some code into helpers
   as well. The code is organized a lot better like this, and io_uring.c
   is now < 4K LOC (me).

 - Deprecate the epoll_ctl opcode. It'll still work, just trigger a
   warning once if used. If we don't get any complaints on this, and I
   don't expect any, then we can fully remove it in a future release
   (me).

 - Improve the cancel hash locking (Hao)

 - kbuf cleanups (Hao)

 - Efficiency improvements to the task_work handling (Dylan, Pavel)

 - Provided buffer improvements (Dylan)

 - Add support for recv/recvmsg multishot support. This is similar to
   the accept (or poll) support for have for multishot, where a single
   SQE can trigger everytime data is received. For applications that
   expect to do more than a few receives on an instantiated socket, this
   greatly improves efficiency (Dylan).

 - Efficiency improvements for poll handling (Pavel)

 - Poll cancelation improvements (Pavel)

 - Allow specifiying a range for direct descriptor allocations (Pavel)

 - Cleanup the cqe32 handling (Pavel)

 - Move io_uring types to greatly cleanup the tracing (Pavel)

 - Tons of great code cleanups and improvements (Pavel)

 - Add a way to do sync cancelations rather than through the sqe -> cqe
   interface, as that's a lot easier to use for some use cases (me).

 - Add support to IORING_OP_MSG_RING for sending direct descriptors to a
   different ring. This avoids the usually problematic SCM case, as we
   disallow those. (me)

 - Make the per-command alloc cache we use for apoll generic, place
   limits on it, and use it for netmsg as well (me).

 - Various cleanups (me, Michal, Gustavo, Uros)

Pull power management updates from Rafael Wysocki:
 "These are mostly minor improvements all over including new CPU IDs for
  the Intel RAPL driver, an Energy Model rework to use micro-Watt as the
  power unit, cpufreq fixes and cleanus, cpuidle updates, devfreq
  updates, documentation cleanups and a new version of the pm-graph
  suite of utilities.

  Specifics:

   - Make cpufreq_show_cpus() more straightforward (Viresh Kumar).

   - Drop unnecessary CPU hotplug locking from store() used by cpufreq
     sysfs attributes (Viresh Kumar).

   - Make the ACPI cpufreq driver support the boost control interface on
     Zhaoxin/Centaur processors (Tony W Wang-oc).

   - Print a warning message on attempts to free an active cpufreq
     policy which should never happen (Viresh Kumar).

   - Fix grammar in the Kconfig help text for the loongson2 cpufreq
     driver (Randy Dunlap).

   - Use cpumask_var_t for an on-stack CPU mask in the ondemand cpufreq
     governor (Zhao Liu).

   - Add trace points for guest_halt_poll_ns grow/shrink to the haltpoll
     cpuidle driver (Eiichi Tsukata).

   - Modify intel_idle to treat C1 and C1E as independent idle states on
     Sapphire Rapids (Artem Bityutskiy).

   - Extend support for wakeirq to callback wrappers used during system
     suspend and resume (Ulf Hansson).

   - Defer waiting for device probe before loading a hibernation image
     till the first actual device access to avoid possible deadlocks
     reported by syzbot (Tetsuo Handa).

   - Unify device_init_wakeup() for PM_SLEEP and !PM_SLEEP (Bjorn
     Helgaas).

   - Add Raptor Lake-P to the list of processors supported by the Intel
     RAPL driver (George D Sworo).

   - Add Alder Lake-N and Raptor Lake-P to the list of processors for
     which Power Limit4 is supported in the Intel RAPL driver (Sumeet
     Pawnikar).

   - Make pm_genpd_remove() check genpd_debugfs_dir against NULL before
     attempting to remove it (Hsin-Yi Wang).

   - Change the Energy Model code to represent power in micro-Watts and
     adjust its users accordingly (Lukasz Luba).

   - Add new devfreq driver for Mediatek CCI (Cache Coherent
     Interconnect) (Johnson Wang).

   - Convert the Samsung Exynos SoC Bus bindings to DT schema of
     exynos-bus.c (Krzysztof Kozlowski).

   - Address kernel-doc warnings by adding the description for unused
     function parameters in devfreq core (Mauro Carvalho Chehab).

   - Use NULL to pass a null pointer rather than zero according to the
     function propotype in imx-bus.c (Colin Ian King).

   - Print error message instead of error interger value in
     tegra30-devfreq.c (Dmitry Osipenko).

   - Add checks to prevent setting negative frequency QoS limits for
     CPUs (Shivnandan Kumar).

   - Update the pm-graph suite of utilities to the latest revision 5.9
     including multiple improvements (Todd Brandt).

   - Drop pme_interrupt reference from the PCI power management
     documentation (Mario Limonciello)"

After v5.19 had all drivers converted to the new atomic API and nobody
 has reported any breakage, this set of changes starts by dropping the

 Some existing drivers get improvements and broader chip support and a

0805c6fb39 spi: Updates for v5.20
The big update this time around is some excellent work from David Jander
 who went through the fast path and really eliminated overheads, meaning
 that we are seeing a huge reduction in the time spent between transfers
 for single threaded clients. Benchmarking has been coming out at about a
 halving of overhead which is clearly visible in system level usage that
 stresses SPI like some CAN and IIO applications, especially with small
 transfers. Thanks to David for taking the time to drill down into this
 and push the work upstream.
 
 Otherwise there's been a bunch of new device support and the usual
 
  - Optimisation of the fast path, particularly around the number and
    types of locking operations, from David Jander.
  - Support for Arbel NPCM845, HP GXP, Intel Meteor Lake and Thunder Bay,
    MediaTek MT8188 and MT8365, Microchip FPGAs, nVidia Tegra 241 and
    Samsung Exynos Auto v9 and 4210.

  CAN and IIO applications, especially with small transfers. Thanks to
  David for taking the time to drill down into this and push the work
  upstream.

  Otherwise there's been a bunch of new device support and the usual
  updates.

   - Optimisation of the fast path, particularly around the number and
     types of locking operations, from David Jander.

   - Support for Arbel NPCM845, HP GXP, Intel Meteor Lake and Thunder

7d0d3fa733 ARM: boardfile deprecation for 6.0
Over the past ten years, new machine support was based on device tree,
 and an initial set of about 400 boards using ATAGS with boardfile
 for booting were grandfathered in, with about half of them either
 removed or converted to DT over time.
 
 Based on the recent mailing list discussion I started, I have now
 turned the findings into a set of patches that marks most board files as
 'depends on UNUSED_BOARD_FILES', leaving only 38 of the 196 boards.
 
 For the boards that are marked as unused, there are two final chances
 for potential users: The removal is scheduled to take place after the
 longterm stable kernel at the end of 2022, so users can stay on that
 version for another few years, and if anyone still has one of these
 machines and is planning to keep updating kernels beyond that version,
 they can speak up now to have their boards taken off the list again.
 
 Waiting for the LTS release also makes sure that there will be at
 least one longterm kernel that contains the recent multiplatform
 conversion along while still supporting all legacy boards.
 
 The short summary of the current status is:
 
  - The s3c24xx, cns3xxx, iop32x and mv78xx0 platforms have no known
    users and will be removed entirely.
 
  - The mmp and davinci platforms have DT support for the important
    machines and will become DT-only after this.
 
  - s3c64xx, dove, orion5x, and pxa keep some board files to allow
    those to be migrated over to DT more easily, but most board files
    are getting removed now. DT support on these platforms is partially
    working but requires changes to additional drivers for the other
    boards.
 
  - omap1, ep93xx, sa1100, footbridge and rpc have no DT support at
    the moment but have some boards with known users. Removing the board
    files that nobody uses should make it easier to try a DT conversion
    if anyone cares.
 
 There is no explicit timeline what happens with the boards that remain
 after this removal, but I expect to revisit this in the future, and
 with most boards gone, there will be a good time to do a treewide
 review of platform drivers that never gained DT support and have no
 remaining in-tree board files.

3976d758e0 ARM: DT changes for 6.0
As usual, the bulk of the changes for the SoC tree are devicetree file
 updates, and most of these changes are for 64-bit embedded machines.
 As before, there are a ton of style cleanups, and additional hardware
 support for existing machines.
 
 Looking only at the new SoC, the notable additions are:
 
  - A whole family of Broadcom broadband SoCs, both 32-bit and 64-bit:
    BCM63178, BCM63158, BCM4912, BCM6858, BCM6878, BCM6846, BCM63146,
    BCM6856, BCM6855, BCM6756, BCM63148, and BCM6813.
    Each SoC comes with a corresponding reference board.
 
  - The new NXP i.MX93 SoC, the follow-up to the popular i.MX6 and
    i.MX8 embedded SoCs, now using Cortex-A55 cores and the
    Ethos-U65 NPU.
 
  - Qualcomm Snapdragon 8cx Gen3 (SC8280XP), the current high end
    of Arm based Laptop SoCs, and its automotive cousin, the
    SA8540P. The SC8280XP is used in the Lenovo Thinkpad X13s
    laptop that also gets added here in addition to the reference
    boards.

Pull ARM DT updates from Arnd Bergmann:
 "As usual, the bulk of the changes for the SoC tree are devicetree file
  updates, and most of these changes are for 64-bit embedded machines.
  As before, there are a ton of style cleanups, and additional hardware
  support for existing machines.

  Looking only at the new SoC, the notable additions are:

   - A whole family of Broadcom broadband SoCs, both 32-bit and 64-bit:
     BCM63178, BCM63158, BCM4912, BCM6858, BCM6878, BCM6846, BCM63146,
     BCM6856, BCM6855, BCM6756, BCM63148, and BCM6813. Each SoC comes
     with a corresponding reference board.

   - The new NXP i.MX93 SoC, the follow-up to the popular i.MX6 and
     i.MX8 embedded SoCs, now using Cortex-A55 cores and the Ethos-U65
     NPU.

   - Qualcomm Snapdragon 8cx Gen3 (SC8280XP), the current high end of
     Arm based Laptop SoCs, and its automotive cousin, the SA8540P. The
     SC8280XP is used in the Lenovo Thinkpad X13s laptop that also gets
     added here in addition to the reference boards.

   - Allwinner H616, a newer version of the H6 SoC, targeted at
     Set-top-box applications. It comes with dts files for the Orange Pi
     zero2 single-board computer and the X96 Mate set-top-box

   - Marvell Prestera 98DX2530 (AlleyCat5), a network switch chip in the
     Armada SoC family based on the Cortex-A55 core.

e233cc59d0 ARM: SoC updates for 6.0
The updates for arch/arm/mach-* platform code this time are mainly
 minor cleanups.
 
 Most notably, the DaVinci DM644x/DM646x SoC support gets removed. This was
 also scheduled for later removal early next year, but Linus Walleij asked
 for having them removed earlier to avoid problems for the GPIO subsystem.

    that can lose the lock_type & cause false reports. No such mishap was
    observed in the wild.
 
  - jump_label improvements: simplify the cross-arch support of

b167fdffe9 This cycle's scheduler updates for v6.0 are:
Load-balancing improvements:
 ============================
 
 - Improve NUMA balancing on AMD Zen systems for affine workloads.
 
 - Improve the handling of reduced-capacity CPUs in load-balancing.
 
 - Energy Model improvements: fix & refine all the energy fairness metrics (PELT),
   and remove the conservative threshold requiring 6% energy savings to
   migrate a task. Doing this improves power efficiency for most workloads,
   and also increases the reliability of energy-efficiency scheduling.
 
 - Optimize/tweak select_idle_cpu() to spend (much) less time searching
   for an idle CPU on overloaded systems. There's reports of several
   milliseconds spent there on large systems with large workloads ...
 
   [ Since the search logic changed, there might be behavioral side effects. ]
 
 - Improve NUMA imbalance behavior. On certain systems
   with spare capacity, initial placement of tasks is non-deterministic,
   and such an artificial placement imbalance can persist for a long time,
   hurting (and sometimes helping) performance.
 
   The fix is to make fork-time task placement consistent with runtime
   NUMA balancing placement.
 
   Note that some performance regressions were reported against this,
   caused by workloads that are not memory bandwith limited, which benefit
   from the artificial locality of the placement bug(s). Mel Gorman's
   conclusion, with which we concur, was that consistency is better than
   random workload benefits from non-deterministic bugs:
 
      "Given there is no crystal ball and it's a tradeoff, I think it's
       better to be consistent and use similar logic at both fork time
       and runtime even if it doesn't have universal benefit."
 
 - Improve core scheduling by fixing a bug in sched_core_update_cookie() that
   caused unnecessary forced idling.
 
 - Improve wakeup-balancing by allowing same-LLC wakeup of idle CPUs for newly
   woken tasks.
 
 - Fix a newidle balancing bug that introduced unnecessary wakeup latencies.
 
 ABI improvements/fixes:
 =======================
 
 - Do not check capabilities and do not issue capability check denial messages
   when a scheduler syscall doesn't require privileges. (Such as increasing niceness.)
 
 - Add forced-idle accounting to cgroups too.
 
 - Fix/improve the RSEQ ABI to not just silently accept unknown flags.
   (No existing tooling is known to have learned to rely on the previous behavior.)
 
 - Depreciate the (unused) RSEQ_CS_FLAG_NO_RESTART_ON_* flags.
 
 Optimizations:
 ==============
 
 - Optimize & simplify leaf_cfs_rq_list()
 
 - Micro-optimize set_nr_{and_not,if}_polling() via try_cmpxchg().
 
 Misc fixes & cleanups:
 ======================
 
 - Fix the RSEQ self-tests on RISC-V and Glibc 2.35 systems.
 
 - Fix a full-NOHZ bug that can in some cases result in the tick not being
   re-enabled when the last SCHED_RT task is gone from a runqueue but there's
   still SCHED_OTHER tasks around.
 
 - Various PREEMPT_RT related fixes.
 
 - Misc cleanups & smaller fixes.

aa16fb4b9e smack: Remove the redundant lsm_inode_alloc
It's not possible for inode->i_security to be NULL here because every
inode will call inode_init_always and then lsm_inode_alloc to alloc
memory for inode->security, this is what LSM infrastructure management
do, so remove this redundant code.
