3be20b6fc1 This is the second round of ext4 commits for 5.8 merge window. It
includes the per-inode DAX support, which was dependant on the DAX
 infrastructure which came in via the XFS tree, and a number of
 regression and bug fixes; most notably the "BUG: using
 smp_processor_id() in preemptible code in ext4_mb_new_blocks" reported
 by syzkaller.

Pull i2c updates from Wolfram Sang:
 "I2C has quite some patches for you this time. I hope it is the move to
  per-driver-maintainers which is now showing results. We will see.

  The big news is two new drivers (Nuvoton NPCM and Qualcomm CCI),
  larger refactoring of the Designware, Tegra, and PXA drivers, the
  Cadence driver supports being a slave now, and there is support to
  instanciate SPD eeproms for well-known cases (which will be
  user-visible because the i801 driver supports it), and some
  devm_platform_ioremap_resource() conversions which blow up the
  diffstat.

  Note that I applied the Nuvoton driver quite late, so some minor fixup
  patches arrived during the merge window. I chose to apply them right
  away because they were trivial"

Merge tag 'notifications-20200601' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

Pull notification queue from David Howells:
 "This adds a general notification queue concept and adds an event
  source for keys/keyrings, such as linking and unlinking keys and
  changing their attributes.

  Thanks to Debarshi Ray, we do have a pull request to use this to fix a
  problem with gnome-online-accounts - as mentioned last time:

     https://gitlab.gnome.org/GNOME/gnome-online-accounts/merge_requests/47

  Without this, g-o-a has to constantly poll a keyring-based kerberos
  cache to find out if kinit has changed anything.

  [ There are other notification pending: mount/sb fsinfo notifications
    for libmount that Karel Zak and Ian Kent have been working on, and
    Christian Brauner would like to use them in lxc, but let's see how
    this one works first ]

  LSM hooks are included:

   - A set of hooks are provided that allow an LSM to rule on whether or
     not a watch may be set. Each of these hooks takes a different
     "watched object" parameter, so they're not really shareable. The
     LSM should use current's credentials. [Wanted by SELinux & Smack]

   - A hook is provided to allow an LSM to rule on whether or not a
     particular message may be posted to a particular queue. This is
     given the credentials from the event generator (which may be the
     system) and the watch setter. [Wanted by Smack]

  I've provided SELinux and Smack with implementations of some of these
  hooks.

  WHY
  ===

  Key/keyring notifications are desirable because if you have your
  kerberos tickets in a file/directory, your Gnome desktop will monitor
  that using something like fanotify and tell you if your credentials
  cache changes.

  However, we also have the ability to cache your kerberos tickets in
  the session, user or persistent keyring so that it isn't left around
  on disk across a reboot or logout. Keyrings, however, cannot currently
  be monitored asynchronously, so the desktop has to poll for it - not
  so good on a laptop. This facility will allow the desktop to avoid the
  need to poll.

  DESIGN DECISIONS
  ================

   - The notification queue is built on top of a standard pipe. Messages
     are effectively spliced in. The pipe is opened with a special flag:

        pipe2(fds, O_NOTIFICATION_PIPE);

     The special flag has the same value as O_EXCL (which doesn't seem
     like it will ever be applicable in this context)[?]. It is given up
     front to make it a lot easier to prohibit splice&co from accessing
     the pipe.

     [?] Should this be done some other way?  I'd rather not use up a new
         O_* flag if I can avoid it - should I add a pipe3() system call
         instead?

     The pipe is then configured::

        ioctl(fds[1], IOC_WATCH_QUEUE_SET_SIZE, queue_depth);
        ioctl(fds[1], IOC_WATCH_QUEUE_SET_FILTER, &filter);

     Messages are then read out of the pipe using read().

   - It should be possible to allow write() to insert data into the
     notification pipes too, but this is currently disabled as the
     kernel has to be able to insert messages into the pipe *without*
     holding pipe->mutex and the code to make this work needs careful
     auditing.

   - sendfile(), splice() and vmsplice() are disabled on notification
     pipes because of the pipe->mutex issue and also because they
     sometimes want to revert what they just did - but one or more
     notification messages might've been interleaved in the ring.

   - The kernel inserts messages with the wait queue spinlock held. This
     means that pipe_read() and pipe_write() have to take the spinlock
     to update the queue pointers.

   - Records in the buffer are binary, typed and have a length so that
     they can be of varying size.

     This allows multiple heterogeneous sources to share a common
     buffer; there are 16 million types available, of which I've used
     just a few, so there is scope for others to be used. Tags may be
     specified when a watchpoint is created to help distinguish the
     sources.

   - Records are filterable as types have up to 256 subtypes that can be
     individually filtered. Other filtration is also available.

   - Notification pipes don't interfere with each other; each may be
     bound to a different set of watches. Any particular notification
     will be copied to all the queues that are currently watching for it
     - and only those that are watching for it.

   - When recording a notification, the kernel will not sleep, but will
     rather mark a queue as having lost a message if there's
     insufficient space. read() will fabricate a loss notification
     message at an appropriate point later.

   - The notification pipe is created and then watchpoints are attached
     to it, using one of:

        keyctl_watch_key(KEY_SPEC_SESSION_KEYRING, fds[1], 0x01);
        watch_mount(AT_FDCWD, "/", 0, fd, 0x02);
        watch_sb(AT_FDCWD, "/mnt", 0, fd, 0x03);

     where in both cases, fd indicates the queue and the number after is
     a tag between 0 and 255.

   - Watches are removed if either the notification pipe is destroyed or
     the watched object is destroyed. In the latter case, a message will
     be generated indicating the enforced watch removal.

  Things I want to avoid:

   - Introducing features that make the core VFS dependent on the
     network stack or networking namespaces (ie. usage of netlink).

   - Dumping all this stuff into dmesg and having a daemon that sits
     there parsing the output and distributing it as this then puts the
     responsibility for security into userspace and makes handling
     namespaces tricky. Further, dmesg might not exist or might be
     inaccessible inside a container.

   - Letting users see events they shouldn't be able to see.

  TESTING AND MANPAGES
  ====================

   - The keyutils tree has a pipe-watch branch that has keyctl commands
     for making use of notifications. Proposed manual pages can also be
     found on this branch, though a couple of them really need to go to
     the main manpages repository instead.

     If the kernel supports the watching of keys, then running "make
     test" on that branch will cause the testing infrastructure to spawn
     a monitoring process on the side that monitors a notifications pipe
     for all the key/keyring changes induced by the tests and they'll
     all be checked off to make sure they happened.

        https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/keyutils.git/log/?h=pipe-watch

   - A test program is provided (samples/watch_queue/watch_test) that
     can be used to monitor for keyrings, mount and superblock events.
     Information on the notifications is simply logged to stdout"

b791d1bdf9 The Kernel Concurrency Sanitizer (KCSAN)
KCSAN is a dynamic race detector, which relies on compile-time
 instrumentation, and uses a watchpoint-based sampling approach to detect
 races.
 
 The feature was under development for quite some time and has already found
 legitimate bugs.
 
 Unfortunately it comes with a limitation, which was only understood late in
 the development cycle:
 
   It requires an up to date CLANG-11 compiler
 
 CLANG-11 is not yet released (scheduled for June), but it's the only
 compiler today which handles the kernel requirements and especially the
 annotations of functions to exclude them from KCSAN instrumentation
 correctly.
 
 These annotations really need to work so that low level entry code and
 especially int3 text poke handling can be completely isolated.
 
 A detailed discussion of the requirements and compiler issues can be found
 here:
 
   https://lore.kernel.org/lkml/CANpmjNMTsY_8241bS7=XAfqvZHFLrVEkv_uM4aDUWE_kh3Rvbw@mail.gmail.com/
 
 We came to the conclusion that trying to work around compiler limitations
 and bugs again would end up in a major trainwreck, so requiring a working
 compiler seemed to be the best choice.
 
 For Continous Integration purposes the compiler restriction is manageable
 and that's where most xxSAN reports come from.
 
 For a change this limitation might make GCC people actually look at their
 bugs. Some issues with CSAN in GCC are 7 years old and one has been 'fixed'
 3 years ago with a half baken solution which 'solved' the reported issue
 but not the underlying problem.
 
 The KCSAN developers also ponder to use a GCC plugin to become independent,
 but that's not something which will show up in a few days.
 
 Blocking KCSAN until wide spread compiler support is available is not a
 really good alternative because the continuous growth of lockless
 optimizations in the kernel demands proper tooling support.

b5265c813c lib/lzo: fix ambiguous encoding bug in lzo-rle
In some rare cases, for input data over 32 KB, lzo-rle could encode two
different inputs to the same compressed representation, so that
decompression is then ambiguous (i.e.  data may be corrupted - although
zram is not affected because it operates over 4 KB pages).

This modifies the compressor without changing the decompressor or the
bitstream format, such that:

 - there is no change to how data produced by the old compressor is
   decompressed

 - an old decompressor will correctly decode data from the updated
   compressor

 - performance and compression ratio are not affected

 - we avoid introducing a new bitstream format

In testing over 12.8M real-world files totalling 903 GB, three files
were affected by this bug.  I also constructed 37M semi-random 64 KB
files totalling 2.27 TB, and saw no affected files.  Finally I tested
over files constructed to contain each of the ~1024 possible bad input
sequences; for all of these cases, updated lzo-rle worked correctly.

There is no significant impact to performance or compression ratio.

0db958b689 dt-bindings: Fix more incorrect 'reg' property sizes in examples
The examples template is a 'simple-bus' with a size of 1 cell for
had between 2 and 4 cells which really only errors on I2C or SPI type
devices with a single cell.

The easiest fix in most cases is to change the 'reg' property to 1 cell
for address and size.

086e9074f5 dt-bindings: Remove more cases of 'allOf' containing a '$ref'
Another round of 'allOf' removals that came in this cycle.

json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.

This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.

   https://lore.kernel.org/r/1588348912-24781-1-git-send-email-bfields@redhat.com
   The result is Tejun Heo's suggestion, and he was OK with this going

Pull READ/WRITE_ONCE rework from Will Deacon:
 "This the READ_ONCE rework I've been working on for a while, which
  bumps the minimum GCC version and improves code-gen on arm64 when
  stack protector is enabled"

[ Side note: I'm _really_ tempted to raise the minimum gcc version to
  4.9, so that we can just say that we require _Generic() support.

  That would allow us to more cleanly handle a lot of the cases where we
  depend on very complex macros with 'sizeof' or __builtin_choose_expr()
  with __builtin_types_compatible_p() etc.

  This branch has a workaround for sparse not handling _Generic(),
  either, but that was already fixed in the sparse development branch,
  so it's really just gcc-4.9 that we'd require.   - Linus ]

6f630784cc This time around we have 4 lines of diff in the core framework, removing a
function that isn't used anymore. Otherwise the main new thing for the common
 clk framework is that it is selectable in the Kconfig language now. Hopefully
 this will let clk drivers and clk consumers be testable on more than the
 architectures that support the clk framework. The goal is to introduce some
 Kunit tests for the framework.
 
 Outside of the core framework we have the usual set of various driver updates
 and non-critical fixes. The dirstat shows that the new Baikal-T1 driver is the
 largest addition this time around in terms of lines of code. After that the x86
 (Intel), Qualcomm, and Mediatek drivers introduce many lines to support new or
 upcoming SoCs. After that the dirstat shows the usual suspects working on their
 SoC support by fixing minor bugs, correcting data and converting some of their
 DT bindings to YAML.
 
 Core:
  - Allow the COMMON_CLK config to be selectable
 
 New Drivers:
  - Clk driver for Baikal-T1 SoCs
  - Mediatek MT6765 clock support
  - Support for Intel Agilex clks
  - Add support for X1830 and X1000 Ingenic SoC clk controllers
  - Add support for the new Renesas RZ/G1H (R8A7742) SoC
  - Add support for Qualcomm's MSM8939 Generic Clock Controller
 
 Updates:
  - Support IDT VersaClock 5P49V5925
  - Bunch of updates for HSDK clock generation unit (CGU) driver
  - Start making audio and GPU clks work on Marvell MMP2/MMP3 SoCs
  - Add some GPU, NPU, and UFS clks to Qualcomm SM8150 driver
  - Enable supply regulators for GPU gdscs on Qualcomm SoCs
  - Add support for Si5342, Si5344 and Si5345 chips
  - Support custom flags in Xilinx zynq firmware
  - Various small fixes to the Xilinx clk driver
  - A single minor rounding fix for the legacy Allwinner clock support
  - A few patches from Abel Vesa as preparation of adding audiomix clock support
    on i.MX
  - A couple of cleanups from Anson Huang for i.MX clk-sscg-pll and clk-pllv3
    drivers
  - Drop dependency on ARM64 for i.MX8M clock driver, to support aarch32 mode on
    aarch64 hardware
  - A series from Peng Fan to improve i.MX8M clock drivers, using composite
    clock for core and bus clk slice
  - Set a better parent clock for flexcan on i.MX6UL to support CiA102 defined
    bit rates
  - A couple changes for EMC frequency scaling on Tegra210
  - Support for CPU frequency scaling on Tegra20/Tegra30
  - New clk gate for CSI test pattern generator on Tegra210
  - Regression fixes for Samsung exynos542x and exynos5433 SoCs
  - Use of fallthrough; attribute for Samsung s3c24xx
  - Updates and fixup HDMI and video clocks on Meson8b
  - Fixup reset polarity on Meson8b
  - Fix GPU glitch free mux switch on Meson gx and g12
  - A minor fix for the currently unused suspend/resume handling on Renesas RZ/A1 and RZ/A2
  - Two more conversions of Renesas DT bindings to json-schema
  - Add support for the USB 2.0 clock selector on Renesas R-Car M3-W+

The improved paragraph about line lengths contains a sentence with a

second one at the beginning of the next line.

Drop the first one, as that one is part of the longest line.

42612e7763 f2fs-for-5.8-rc1
In this round, we've added some knobs to enhance compression feature and harden
 testing environment. In addition, we've fixed several bugs reported from Android
 devices such as long discarding latency, device hanging during quota_sync, etc.
 
 Enhancement:
 - support lzo-rle algorithm
 - add two ioctls to release and reserve blocks for compression
 - support partial truncation/fiemap on compressed file
 - introduce sysfs entries to attach IO flags explicitly
 - add iostat trace point along with read io stat
 
 Bug fix:
 - fix long discard latency
 - flush quota data by f2fs_quota_sync correctly
 - fix to recover parent inode number for power-cut recovery
 - fix lz4/zstd output buffer budget
 - parse checkpoint mount option correctly
 - avoid inifinite loop to wait for flushing node/meta pages
 - manage discard space correctly
 
 And some refactoring and clean up patches were added.

8b4d37db9a Merge branch 'x86/srbds' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 srbds fixes from Thomas Gleixner:
 "The 9th episode of the dime novel "The performance killer" with the
  subtitle "Slow Randomizing Boosts Denial of Service".

  SRBDS is an MDS-like speculative side channel that can leak bits from
  the random number generator (RNG) across cores and threads. New
  microcode serializes the processor access during the execution of
  RDRAND and RDSEED. This ensures that the shared buffer is overwritten
  before it is released for reuse. This is equivalent to a full bus
  lock, which means that many threads running the RNG instructions in
  parallel have the same effect as the same amount of threads issuing a
  locked instruction targeting an address which requires locking of two
  cachelines at once.

  The mitigation support comes with the usual pile of unpleasant
  ingredients:

   - command line options

   - sysfs file

   - microcode checks

   - a list of vulnerable CPUs identified by model and stepping this
     time which requires stepping match support for the cpu match logic.

   - the inevitable slowdown of affected CPUs"

* branch 'x86/srbds' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86/speculation: Add Ivy Bridge to affected list
  x86/speculation: Add SRBDS vulnerability and mitigation documentation
  x86/speculation: Add Special Register Buffer Data Sampling (SRBDS) mitigation
  x86/cpu: Add 'table' argument to cpu_matches()

32b6aba85c f2fs: add node_io_flag for bio flags likewise data_io_flag
This patch adds another way to attach bio flags to node writes.

Description:   Give a way to attach REQ_META|FUA to node writes
               given temperature-based bits. Now the bits indicate:
               *      REQ_META     |      REQ_FUA      |
               *    5 |    4 |   3 |    2 |    1 |   0 |

abfbb29297 remoteproc updates for v5.8
This introduces device managed versions of functions used to register
 remoteproc devices, add support for remoteproc driver specific resource
 control, enables remoteproc drivers to specify ELF class and machine for
 coredumps. It integrates pm_runtime in the core for keeping resources
 active while the remote is booted and holds a wake source while
 recoverying a remote processor after a firmware crash.
 
 It refactors the remoteproc device's allocation path to simplify the
 logic, fix a few cleanup bugs and to not clone const strings onto the
 heap. Debugfs code is simplifies using the DEFINE_SHOW_ATTRIBUTE and a
 zero-length array is replaced with flexible-array.
 
 A new remoteproc driver for the JZ47xx VPU is introduced, the Qualcomm
 SM8250 gains support for audio, compute and sensor remoteprocs and the
 Qualcomm SC7180 modem support is cleaned up and improved.
 
 The Qualcomm glink subsystem-restart driver is merged into the main
 glink driver, the Qualcomm sysmon driver is extended to properly notify
 remote processors about all other remote processors' state transitions.
