625434dafd Merge tag 'for-5.13/io_uring-2021-04-27' of git://git.kernel.dk/linux-block
Pull io_uring updates from Jens Axboe:

 - Support for multi-shot mode for POLL requests

 - More efficient reference counting. This is shamelessly stolen from
   the mm side. Even though referencing is mostly single/dual user, the
   128 count was retained to keep the code the same. Maybe this
   should/could be made generic at some point.

 - Removal of the need to have a manager thread for each ring. The
   manager threads only job was checking and creating new io-threads as
   needed, instead we handle this from the queue path.

 - Allow SQPOLL without CAP_SYS_ADMIN or CAP_SYS_NICE. Since 5.12, this
   thread is "just" a regular application thread, so no need to restrict
   use of it anymore.

 - Cleanup of how internal async poll data lifetime is managed.

 - Fix for syzbot reported crash on SQPOLL cancelation.

 - Make buffer registration more like file registrations, which includes
   flexibility in avoiding full set unregistration and re-registration.

 - Fix for io-wq affinity setting.

 - Be a bit more defensive in task->pf_io_worker setup.

 - Various SQPOLL fixes.

 - Cleanup of SQPOLL creds handling.

 - Improvements to in-flight request tracking.

 - File registration cleanups.

 - Tons of cleanups and little fixes

16b3d0cf5b Merge tag 'sched-core-2021-04-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull scheduler updates from Ingo Molnar:

 - Clean up SCHED_DEBUG: move the decades old mess of sysctl, procfs and
   debugfs interfaces to a unified debugfs interface.

 - Signals: Allow caching one sigqueue object per task, to improve
   performance & latencies.

 - Improve newidle_balance() irq-off latencies on systems with a large
   number of CPU cgroups.

 - Improve energy-aware scheduling

 - Improve the PELT metrics for certain workloads

 - Reintroduce select_idle_smt() to improve load-balancing locality -
   but without the previous regressions

 - Add 'scheduler latency debugging': warn after long periods of pending
   need_resched. This is an opt-in feature that requires the enabling of
   the LATENCY_WARN scheduler feature, or the use of the
   resched_latency_warn_ms=xx boot parameter.

 - CPU hotplug fixes for HP-rollback, and for the 'fail' interface. Fix
   remaining balance_push() vs. hotplug holes/races

 - PSI fixes, plus allow /proc/pressure/ files to be written by
   CAP_SYS_RESOURCE tasks as well

 - Fix/improve various load-balancing corner cases vs. capacity margins

 - Fix sched topology on systems with NUMA diameter of 3 or above

 - Fix PF_KTHREAD vs to_kthread() race

 - Minor rseq optimizations

 - Misc cleanups, optimizations, fixes and smaller updates

42dec9a936 Merge tag 'perf-core-2021-04-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf event updates from Ingo Molnar:

 - Improve Intel uncore PMU support:

     - Parse uncore 'discovery tables' - a new hardware capability
       enumeration method introduced on the latest Intel platforms. This
       table is in a well-defined PCI namespace location and is read via
       MMIO. It is organized in an rbtree.

       These uncore tables will allow the discovery of standard counter
       blocks, but fancier counters still need to be enumerated
       explicitly.

     - Add Alder Lake support

     - Improve IIO stacks to PMON mapping support on Skylake servers

 - Add Intel Alder Lake PMU support - which requires the introduction of
   'hybrid' CPUs and PMUs. Alder Lake is a mix of Golden Cove ('big')
   and Gracemont ('small' - Atom derived) cores.

   The CPU-side feature set is entirely symmetrical - but on the PMU
   side there's core type dependent PMU functionality.

 - Reduce data loss with CPU level hardware tracing on Intel PT / AUX
   profiling, by fixing the AUX allocation watermark logic.

 - Improve ring buffer allocation on NUMA systems

 - Put 'struct perf_event' into their separate kmem_cache pool

 - Add support for synchronous signals for select perf events. The
   immediate motivation is to support low-overhead sampling-based race
   detection for user-space code. The feature consists of the following
   main changes:

     - Add thread-only event inheritance via
       perf_event_attr::inherit_thread, which limits inheritance of
       events to CLONE_THREAD.

     - Add the ability for events to not leak through exec(), via
       perf_event_attr::remove_on_exec.

     - Allow the generation of SIGTRAP via perf_event_attr::sigtrap,
       extend siginfo with an u64 ::si_perf, and add the breakpoint
       information to ::si_addr and ::si_perf if the event is
       PERF_TYPE_BREAKPOINT.

   The siginfo support is adequate for breakpoints right now - but the
   new field can be used to introduce support for other types of
   metadata passed over siginfo as well.

 - Misc fixes, cleanups and smaller updates.

e7c6e405e1 Fix misc new gcc warnings
It seems like Fedora 34 ends up enabling a few new gcc warnings, notably
"-Wstringop-overread" and "-Warray-parameter".

Both of them cause what seem to be valid warnings in the kernel, where
we have array size mismatches in function arguments (that are no longer
just silently converted to a pointer to element, but actually checked).

This fixes most of the trivial ones, by making the function declaration
match the function definition, and in the case of intel_pm.c, removing
the over-specified array size from the argument declaration.

At least one 'stringop-overread' warning remains in the i915 driver, but
that one doesn't have the same obvious trivial fix, and may or may not
actually be indicative of a bug.

[ It was a mistake to upgrade one of my machines to Fedora 34 while
  being busy with the merge window, but if this is the extent of the
  compiler upgrade problems, things are better than usual    - Linus ]

Pull AFS updates from David Howells:
 "Use the new netfs lib.

  Begin the process of overhauling the use of the fscache API by AFS and
  the introduction of support for features such as Transparent Huge
  Pages (THPs).

   - Add some support for THPs, including using core VM helper functions
     to find details of pages.

   - Use the ITER_XARRAY I/O iterator to mediate access to the pagecache
     as this handles THPs and doesn't require allocation of large bvec
     arrays.

   - Delegate address_space read/pre-write I/O methods for AFS to the
     netfs helper library. A method is provided to the library that
     allows it to issue a read against the server.

     This includes a change in use for PG_fscache (it now indicates a
     DIO write in progress from the marked page), so a number of waits
     need to be deployed for it.

   - Split the core AFS writeback function to make it easier to modify
     in future patches to handle writing to the cache. [This might
     feasibly make more sense moved out into my fscache-iter branch].

  I've tested these with "xfstests -g quick" against an AFS volume
  (xfstests needs patching to make it work). With this, AFS without a
  cache passes all expected xfstests; with a cache, there's an extra
  failure, but that's also there before these patches. Fixing that
  probably requires a greater overhaul (as can be found on my
  fscache-iter branch, but that's for a later time).

  Thanks should go to Marc Dionne and Jeff Altman of AuriStor for
  exercising the patches in their test farm also"

Pull network filesystem helper library updates from David Howells:
 "Here's a set of patches for 5.13 to begin the process of overhauling
  the local caching API for network filesystems. This set consists of
  two parts:

  (1) Add a helper library to handle the new VM readahead interface.

      This is intended to be used unconditionally by the filesystem
      (whether or not caching is enabled) and provides a common
      framework for doing caching, transparent huge pages and, in the
      future, possibly fscrypt and read bandwidth maximisation. It also
      allows the netfs and the cache to align, expand and slice up a
      read request from the VM in various ways; the netfs need only
      provide a function to read a stretch of data to the pagecache and
      the helper takes care of the rest.

  (2) Add an alternative fscache/cachfiles I/O API that uses the kiocb
      facility to do async DIO to transfer data to/from the netfs's
      pages, rather than using readpage with wait queue snooping on one
      side and vfs_write() on the other. It also uses less memory, since
      it doesn't do buffered I/O on the backing file.

      Note that this uses SEEK_HOLE/SEEK_DATA to locate the data
      available to be read from the cache. Whilst this is an improvement
      from the bmap interface, it still has a problem with regard to a
      modern extent-based filesystem inserting or removing bridging
      blocks of zeros. Fixing that requires a much greater overhaul.

  This is a step towards overhauling the fscache API. The change is
  opt-in on the part of the network filesystem. A netfs should not try
  to mix the old and the new API because of conflicting ways of handling
  pages and the PG_fscache page flag and because it would be mixing DIO
  with buffered I/O. Further, the helper library can't be used with the
  old API.

  This does not change any of the fscache cookie handling APIs or the
  way invalidation is done at this time.

  In the near term, I intend to deprecate and remove the old I/O API
  (fscache_allocate_page{,s}(), fscache_read_or_alloc_page{,s}(),
  fscache_write_page() and fscache_uncache_page()) and eventually
  replace most of fscache/cachefiles with something simpler and easier
  to follow.

  This patchset contains the following parts:

   - Some helper patches, including provision of an ITER_XARRAY iov
     iterator and a function to do readahead expansion.

   - Patches to add the netfs helper library.

   - A patch to add the fscache/cachefiles kiocb API.

   - A pair of patches to fix some review issues in the ITER_XARRAY and
     read helpers as spotted by Al and Willy.

  Jeff Layton has patches to add support in Ceph for this that he
  intends for this merge window. I have a set of patches to support AFS
  that I will post a separate pull request for.

  With this, AFS without a cache passes all expected xfstests; with a
  cache, there's an extra failure, but that's also there before these
  patches. Fixing that probably requires a greater overhaul. Ceph also
  passes the expected tests.

  I also have patches in a separate branch to tidy up the handling of
  PG_fscache/PG_private_2 and their contribution to page refcounting in
  the core kernel here, but I haven't included them in this set and will
  route them separately"

Pull CFI on arm64 support from Kees Cook:
 "This builds on last cycle's LTO work, and allows the arm64 kernels to
  be built with Clang's Control Flow Integrity feature. This feature has
  happily lived in Android kernels for almost 3 years[1], so I'm excited
  to have it ready for upstream.

  The wide diffstat is mainly due to the treewide fixing of mismatched
  list_sort prototypes. Other things in core kernel are to address
  various CFI corner cases. The largest code portion is the CFI runtime
  implementation itself (which will be shared by all architectures
  implementing support for CFI). The arm64 pieces are Acked by arm64
  maintainers rather than coming through the arm64 tree since carrying
  this tree over there was going to be awkward.

  CFI support for x86 is still under development, but is pretty close.
  There are a handful of corner cases on x86 that need some improvements
  to Clang and objtool, but otherwise works well.

  Summary:

   - Clean up list_sort prototypes (Sami Tolvanen)

   - Introduce CONFIG_CFI_CLANG for arm64 (Sami Tolvanen)"

 "The only core work for SPI this time around is the completion of the
  conversion to the new style method for specifying transfer delays,
  meaning we can cope with what most controllers support more directly
  using conversions in the core rather than open coding in drivers.

  Otherwise it's a good stack of cleanups and fixes plus a few new
  drivers.

     from when it was ITER_MAPPING.

 (2) Fix _copy_mc_to_iter() so that the xarray segment updates count and
     iov_offset in the iterator before returning.

 (3) Fix iov_iter_alignment() to not loop in the xarray case.  Because the
     middle pages are all whole pages, only the end pages need be
     considered - and this can be reduced to just looking at the start
     position in the xarray and the iteration size.

 (4) Fix iov_iter_advance() to limit the size of the advance to no more
     than the remaining iteration size.

Pull btrfs updates from David Sterba:
 "The updates this time are mostly stabilization, preparation and minor
  improvements.

  User visible improvements:

   - readahead for send, improving run time of full send by 10% and for
     incremental by 25%

   - make reflinks respect O_SYNC, O_DSYNC and S_SYNC flags

   - export supported sectorsize values in sysfs (currently only page
     size, more once full subpage support lands)

   - more graceful errors and warnings on 32bit systems when logical
     addresses for metadata reach the limit posed by unsigned long in
     page::index
      - error: fail mount if there's a metadata block beyond the limit
      - error: new metadata block would be at unreachable address
      - warn when 5/8th of the limit is reached, for 4K page systems
        it's 10T, for 64K page it's 160T

   - zoned mode
      - relocated zones get reset at the end instead of discard
      - automatic background reclaim of zones that have 75%+ of unusable
        space, the threshold is tunable in sysfs

  Fixes:

   - fsync and tree mod log fixes

   - fix inefficient preemptive reclaim calculations

   - fix exhaustion of the system chunk array due to concurrent
     allocations

   - fix fallback to no compression when racing with remount

   - preemptive fix for dm-crypt on zoned device that does not properly
     advertise zoned support

  Core changes:

   - add inode lock to synchronize mmap and other block updates (eg.
     deduplication, fallocate, fsync)

   - kmap conversions to new kmap_local API

   - subpage support (continued)
      - new helpers for page state/extent buffer tracking
      - metadata changes now support read and write

   - error handling through out relocation call paths

   - many other cleanups and code simplifications"

Pull ARM devicetree updates from Arnd Bergmann:
 "There are six new SoCs added this time.

  Apple M1 and Nuvoton WPCM450 have separate branches because they are
  new SoC families that require changes outside of device tree files.
  The other four are variations of already supported chips and get
  merged through this branch:

   - STMicroelectronics STM32H750 is one of many variants of STM32
     microcontrollers based on the Cortex-M7 core.

     This is particularly notable since we rarely add support for new
     MMU-less chips these days. In this case, the board that gets added
     along with the platform is not a SoC reference platform but the
     "Art Pi" (https://art-pi.gitee.io/website/) machine that was
     originally design for the RT-Thread RTOS.

   - NXP i.MX8QuadMax is a variant of the growing i.MX8
     embedded/industrial SoC family, using two Cortex-A72 and four
     Cortex-A53 cores.

     It gets added along with its reference board, the "NXP i.MX8QuadMax
     Multisensory Enablement Kit".

   - Qualcomm SC7280 is a Laptop SoC following the SC7180 (Snapdragon
     7c) that is used in some Chromebooks and Windows laptops.

     Only a reference board is added for the moment.

   - TI AM64x Sita4ra is a new version of the K3 SoC family for
     industrial control, motor control, remote IO, IoT gateway etc.,
     similar to the older AM65x family.

     Two reference machines are added alongside.

  Among the newly added machines, there is a very clear skew towards
  64-bit machines now, with 12 32-bit machines compared to 23 64-bit
  machines. The full list sorted by SoC is:

   - ASpeed AST2500 BMC: ASRock E3C246D4I Xeon server board
   - Allwinner A10: Topwise A721 Tablet
   - Amlogic GXL: MeCool KII TV box
   - Amlogic GXM: Mecool KIII, Minix Neo U9-H TV boxes
   - Broadcom BCM4908: TP-Link Archer C2300 V1 router
   - MStar SSD202D: M5Stack UnitV2 camera
   - Marvell Armada 38x: ATL-x530 ethernet switch
   - Mediatek MT8183 Chromebooks: Lenovo 10e, Acer Spin 311, Asus Flip
     CM3, Asus Detachable CM3
   - Mediatek MT8516/MT8183: OLogic Pumpkin Board
   - NXP i.MX7: reMarkable Tablet
   - NXP i.MX8M: Kontron pitx-imx8m, Engicam i.Core MX8M Mini
   - Nuvoton NPCM730: Quanta GBS BMC
   - Qualcomm X55: Telit FN980 TLB SoM, Thundercomm TurboX T55 SoM
   - Qualcomm MSM8998: OnePlus 5/5T phones
   - Qualcomm SM8350: Snapdragon 888 Mobile Hardware Development Kit
   - Rockchip RK3399: NanoPi R4S board
   - STM32MP1: Engicam MicroGEA STM32MP1 MicroDev 2.0 and SOM, EDIMM2.2
     Starter Kit, Carrier, SOM
   - TI AM65: Siemens SIMATIC IOT2050 gateway

  There is notable work going into extending already supported machines
  and SoCs:

   - ASpeed AST2500
   - Allwinner A23, A83t, A31, A64, H6
   - Amlogic G12B
   - Broadcom BCM4908
   - Marvell Armada 7K/8K/CN91xx
   - Mediatek MT6589, MT7622, MT8173, MT8183, MT8195
   - NXP i.MX8Q, i.MX8MM, i.MX8MP
   - Qualcomm MSM8916, SC7180, SDM845, SDX55, SM8350
   - Renesas R-Car M3, V3U
   - Rockchip RK3328, RK3399
   - STEricsson U8500
   - STMicroelectronics STM32MP141
   - Samsung Exynos 4412
   - TI K3-AM65, K3-J7200
   - TI OMAP3

  Among the treewide cleanups and bug fixes, two parts stand out:

   - There are a number of cleanups for issues pointed out by 'make
     dtbs_check' this time, and I expect more to come in the future as
     we increasingly check for regressions.

   - After a change to the MMC subsystem that can lead to unpredictable
     device numbers, several platforms add 'aliases' properties for
     these to give each MMC controller a fixed number"

     dra7
   - omap-prm driver needs to enable autoidle retention support for
     omap4
   - omap5 clocks are missing gpmc and ocmc clock registers
   - pci-dra7xx now needs to use builtin_platform_driver instead of

 "Here is the big set of staging and IIO driver updates for 5.13-rc1.

  Lots of little churn in here, and some larger churn as well. Major
  things are:

   - removal of wimax drivers, no one has this hardware anymore for this
     failed "experiment".

   - removal of the Google gasket driver, turns out no one wanted to
     maintain it or cares about it anymore, so they asked for it to be
     removed.

   - comedi finally moves out of the staging directory into drivers/comedi

     This is one of the oldest kernel subsystems around, being created
     in the 2.0 kernel days, and was one of the first things added to
     drivers/staging/ when that was created over 15 years ago.

     It should have been moved out of staging a long time ago, it's well
     maintained and used by loads of different devices in the real world
     every day. Nice to see this finally happen.

   - so many tiny coding style cleanups it's not funny.

     Perfect storm of at least 2 different intern project application
     deadlines combined to provide a huge number of new contributions in
     this area from people learning how to do kernel development. Great
     job to everyone involved here.

  There's also the normal updates for IIO drivers with new IIO drivers
  and updates all over that subsystem.

  All of these have been in linux-next for a while with no reported
  issues"

Pull arm64 updates from Catalin Marinas:

 - MTE asynchronous support for KASan. Previously only synchronous
   (slower) mode was supported. Asynchronous is faster but does not
   allow precise identification of the illegal access.

 - Run kernel mode SIMD with softirqs disabled. This allows using NEON
   in softirq context for crypto performance improvements. The
   conditional yield support is modified to take softirqs into account
   and reduce the latency.

 - Preparatory patches for Apple M1: handle CPUs that only have the VHE
   mode available (host kernel running at EL2), add FIQ support.

 - arm64 perf updates: support for HiSilicon PA and SLLC PMU drivers,
   new functions for the HiSilicon HHA and L3C PMU, cleanups.

 - Re-introduce support for execute-only user permissions but only when
   the EPAN (Enhanced Privileged Access Never) architecture feature is
   available.

 - Disable fine-grained traps at boot and improve the documented boot
   requirements.

 - Support CONFIG_KASAN_VMALLOC on arm64 (only with KASAN_GENERIC).

 - Add hierarchical eXecute Never permissions for all page tables.

 - Add arm64 prctl(PR_PAC_{SET,GET}_ENABLED_KEYS) allowing user programs
   to control which PAC keys are enabled in a particular task.

 - arm64 kselftests for BTI and some improvements to the MTE tests.

 - Minor improvements to the compat vdso and sigpage.

eea2647e74 Merge tag 'x86-entry-2021-04-26' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull entry code update from Thomas Gleixner:
 "Provide support for randomized stack offsets per syscall to make
  stack-based attacks harder which rely on the deterministic stack
  layout.

  The feature is based on the original idea of PaX's RANDSTACK feature,
  but uses a significantly different implementation.

  The offset does not affect the pt_regs location on the task stack as
  this was agreed on to be of dubious value. The offset is applied
  before the actual syscall is invoked.

  The offset is stored per cpu and the randomization happens at the end
  of the syscall which is less predictable than on syscall entry.

  The mechanism to apply the offset is via alloca(), i.e. abusing the
  dispised VLAs. This comes with the drawback that
  stack-clash-protection has to be disabled for the affected compilation
  units and there is also a negative interaction with stack-protector.

  Those downsides are traded with the advantage that this approach does
  not require any intrusive changes to the low level assembly entry
  code, does not affect the unwinder and the correct stack alignment is
  handled automatically by the compiler.

  The feature is guarded with a static branch which avoids the overhead
  when disabled.

  Currently this is supported for X86 and ARM64"
