John Hubbard f1f6a7dd9b mm, tree-wide: rename put_user_page*() to unpin_user_page*()
In order to provide a clearer, more symmetric API for pinning and
unpinning DMA pages.  This way, pin_user_pages*() calls match up with
unpin_user_pages*() calls, and the API is a lot closer to being
self-explanatory.

John Hubbard eddb1c228f mm/gup: introduce pin_user_pages*() and FOLL_PIN
Introduce pin_user_pages*() variations of get_user_pages*() calls, and
also pin_longterm_pages*() variations.

For now, these are placeholder calls, until the various call sites are
converted to use the correct get_user_pages*() or pin_user_pages*() API.

These variants will eventually all set FOLL_PIN, which is also
introduced, and thoroughly documented.

    pin_user_pages()
    pin_user_pages_remote()
    pin_user_pages_fast()

All pages that are pinned via the above calls, must be unpinned via
put_user_page().

The underlying rules are:

* FOLL_PIN is a gup-internal flag, so the call sites should not directly
  set it.  That behavior is enforced with assertions.

* Call sites that want to indicate that they are going to do DirectIO
  ("DIO") or something with similar characteristics, should call a
  get_user_pages()-like wrapper call that sets FOLL_PIN.  These wrappers
  will:

    * Start with "pin_user_pages" instead of "get_user_pages".  That
      makes it easy to find and audit the call sites.

    * Set FOLL_PIN

* For pages that are received via FOLL_PIN, those pages must be returned
  via put_user_page().

Thanks to Jan Kara and Vlastimil Babka for explaining the 4 cases in
this documentation.  (I've reworded it and expanded upon it.)

Linus Torvalds 33c84e89ab SCSI misc on 20200129
This series is slightly unusual because it includes Arnd's compat
 ioctl tree here:
 
 1c46a2cf2d Merge tag 'block-ioctl-cleanup-5.6' into 5.6/scsi-queue
 
 Excluding Arnd's changes, this is mostly an update of the usual
 drivers: megaraid_sas, mpt3sas, qla2xxx, ufs, lpfc, hisi_sas.  There
 are a couple of core and base updates around error propagation and
 atomicity in the attribute container base we use for the SCSI
 transport classes.  The rest is minor changes and updates.

Linus Torvalds 6aee4badd8 Merge branch 'work.openat2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull openat2 support from Al Viro:
 "This is the openat2() series from Aleksa Sarai.

  I'm afraid that the rest of namei stuff will have to wait - it got
  zero review the last time I'd posted #work.namei, and there had been a
  leak in the posted series I'd caught only last weekend. I was going to
  repost it on Monday, but the window opened and the odds of getting any
  review during that... Oh, well.

  Anyway, openat2 part should be ready; that _did_ get sane amount of
  review and public testing, so here it comes"

From Aleksa's description of the series:
 "For a very long time, extending openat(2) with new features has been
  incredibly frustrating. This stems from the fact that openat(2) is
  possibly the most famous counter-example to the mantra "don't silently
  accept garbage from userspace" -- it doesn't check whether unknown
  flags are present[1].

  This means that (generally) the addition of new flags to openat(2) has
  been fraught with backwards-compatibility issues (O_TMPFILE has to be
  defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
  kernels gave errors, since it's insecure to silently ignore the
  flag[2]). All new security-related flags therefore have a tough road
  to being added to openat(2).

  Furthermore, the need for some sort of control over VFS's path
  resolution (to avoid malicious paths resulting in inadvertent
  breakouts) has been a very long-standing desire of many userspace
  applications.

  This patchset is a revival of Al Viro's old AT_NO_JUMPS[3] patchset
  (which was a variant of David Drysdale's O_BENEATH patchset[4] which
  was a spin-off of the Capsicum project[5]) with a few additions and
  changes made based on the previous discussion within [6] as well as
  others I felt were useful.

  In line with the conclusions of the original discussion of
  AT_NO_JUMPS, the flag has been split up into separate flags. However,
  instead of being an openat(2) flag it is provided through a new
  syscall openat2(2) which provides several other improvements to the
  openat(2) interface (see the patch description for more details). The
  following new LOOKUP_* flags are added:

  LOOKUP_NO_XDEV:

     Blocks all mountpoint crossings (upwards, downwards, or through
     absolute links). Absolute pathnames alone in openat(2) do not
     trigger this. Magic-link traversal which implies a vfsmount jump is
     also blocked (though magic-link jumps on the same vfsmount are
     permitted).

  LOOKUP_NO_MAGICLINKS:

     Blocks resolution through /proc/$pid/fd-style links. This is done
     by blocking the usage of nd_jump_link() during resolution in a
     filesystem. The term "magic-links" is used to match with the only
     reference to these links in Documentation/, but I'm happy to change
     the name.

     It should be noted that this is different to the scope of
     ~LOOKUP_FOLLOW in that it applies to all path components. However,
     you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it
     will *not* fail (assuming that no parent component was a
     magic-link), and you will have an fd for the magic-link.

     In order to correctly detect magic-links, the introduction of a new
     LOOKUP_MAGICLINK_JUMPED state flag was required.

  LOOKUP_BENEATH:

     Disallows escapes to outside the starting dirfd's
     tree, using techniques such as ".." or absolute links. Absolute
     paths in openat(2) are also disallowed.

     Conceptually this flag is to ensure you "stay below" a certain
     point in the filesystem tree -- but this requires some additional
     to protect against various races that would allow escape using
     "..".

     Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it
     can trivially beam you around the filesystem (breaking the
     protection). In future, there might be similar safety checks done
     as in LOOKUP_IN_ROOT, but that requires more discussion.

  In addition, two new flags are added that expand on the above ideas:

  LOOKUP_NO_SYMLINKS:

     Does what it says on the tin. No symlink resolution is allowed at
     all, including magic-links. Just as with LOOKUP_NO_MAGICLINKS this
     can still be used with NOFOLLOW to open an fd for the symlink as
     long as no parent path had a symlink component.

  LOOKUP_IN_ROOT:

     This is an extension of LOOKUP_BENEATH that, rather than blocking
     attempts to move past the root, forces all such movements to be
     scoped to the starting point. This provides chroot(2)-like
     protection but without the cost of a chroot(2) for each filesystem
     operation, as well as being safe against race attacks that
     chroot(2) is not.

     If a race is detected (as with LOOKUP_BENEATH) then an error is
     generated, and similar to LOOKUP_BENEATH it is not permitted to
     cross magic-links with LOOKUP_IN_ROOT.

     The primary need for this is from container runtimes, which
     currently need to do symlink scoping in userspace[7] when opening
     paths in a potentially malicious container.

     There is a long list of CVEs that could have bene mitigated by
     having RESOLVE_THIS_ROOT (such as CVE-2017-1002101,
     CVE-2017-1002102, CVE-2018-15664, and CVE-2019-5736, just to name a
     few).

  In order to make all of the above more usable, I'm working on
  libpathrs[8] which is a C-friendly library for safe path resolution.
  It features a userspace-emulated backend if the kernel doesn't support
  openat2(2). Hopefully we can get userspace to switch to using it, and
  thus get openat2(2) support for free once it's ready.

  Future work would include implementing things like
  RESOLVE_NO_AUTOMOUNT and possibly a RESOLVE_NO_REMOTE (to allow
  programs to be sure they don't hit DoSes though stale NFS handles)"

Here is the big USB and Thunderbolt and PHY driver updates for 5.6-rc1.
 
 With the advent of USB4, "Thunderbolt" has really become USB4, so the
 renaming of the Kconfig option and starting to share subsystem code has
 begun, hence both subsystems coming in through the same tree here.
 
 PHY driver updates also touched USB drivers, so that is coming in
 through here as well.
 
 Major stuff included in here are:
 	- USB 4 initial support added (i.e. Thunderbolt)
 	- musb driver updates
 	- USB gadget driver updates
 	- PHY driver updates
 	- USB PHY driver updates
 	- lots of USB serial stuff fixed up
 	- USB typec updates
 	- USB-IP fixes
 	- lots of other smaller USB driver updates
 
 All of these have been in linux-next for a while now (the usb-serial

 here), with no reported issues.

     keyring, for example during early boot, before a custom policy has
     been loaded, are queued and only processed after loading the custom
     policy.

   - IMA calculates and caches files hashes. Other kernel subsystems,
     and possibly kernel modules, are interested in accessing these
     cached file hashes.

  The bug fixes prevent classifying a file short read (e.g. shutdown) as
  an invalid file signature, add a missing blank when displaying the
  securityfs policy rules containing LSM labels, and, lastly, fix the
  handling of the IMA policy information for unknown LSM labels"

  IMA: Defined delayed workqueue to free the queued keys

Linus Torvalds fb95aae6e6 sound updates for 5.6-rc1
As diffstat shows we've had again a lot of works done for this cycle:
 majority of changes are the continued componentization and code
 refactoring in ASoC, the tree-wide PCM API updates and cleanups
 and SOF updates while a few ASoC driver updates are seen, too.
 
 Here we go, some highlights:
 
 Core:
 - Finally y2038 support landed to ALSA ABI;
   some ioctls have been extended and lots of tricks were applied
 - Applying the new managed PCM buffer API to all drivers;
   the API itself was already merged in 5.5
 - The already deprecated dimension support in ALSA control API is
   dropped completely now
 - Verification of ALSA control elements to catch API misuses
 
 ASoC:
 - Further code refactorings and moving things to the component level
 - Lots of updates and improvements on SOF / Intel drivers;
   now including common HDMI driver and SoundWire support
 - New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm
   WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011, RT1015
   and RT1308
 
 HD-audio:
 - Improved ring-buffer communications using waitqueue
 - Drop the superfluous buffer preallocation on x86
 
 Others:
 - Many code cleanups, mostly constifications over the whole tree
 - USB-audio: quirks for MOTU, Corsair Virtuoso, Line6 Helix
 - FireWire: code refactoring for oxfw and dice drivers

Linus Torvalds 3d3b44a61a The interrupt departement provides:
- A mechanism to shield isolated tasks from managed interrupts:
 
    The affinity of managed interrupts is completely controlled by the
    kernel and user space has no influence on them. The reason is that
    the automatically assigned affinity correlates to the multi-queue
    CPU handling of block devices.
 
    If the generated affinity mask spaws both housekeeping and isolated CPUs
    the interrupt could be routed to an isolated CPU which would then be
    disturbed by I/O submitted by a housekeeping CPU.
 
    The new mechamism ensures that as long as one housekeeping CPU is online
    in the assigned affinity mask the interrupt is routed to a housekeeping
    CPU.
 
    If there is no online housekeeping CPU in the affinity mask, then the
    interrupt is routed to an isolated CPU to keep the device queue intact,
    but unless the isolated CPU submits I/O by itself these interrupts are
    not raised.
 
  - A small addon to the device tree irqdomain core code to avoid
    duplication in irq chip drivers
 
  - Conversion of the SiFive PLIC to hierarchical domains
 
  - The usual pile of new irq chip drivers: SiFive GPIO, Aspeed SCI, NXP
    INTMUX, Meson A1 GPIO
 
  - The first cut of support for the new ARM GICv4.1
 
  - The usual pile of fixes and improvements in core and driver code

Linus Torvalds e279160f49 The timekeeping and timers departement provides:
- Time namespace support:
 
     If a container migrates from one host to another then it expects that
     clocks based on MONOTONIC and BOOTTIME are not subject to
     disruption. Due to different boot time and non-suspended runtime these
     clocks can differ significantly on two hosts, in the worst case time
     goes backwards which is a violation of the POSIX requirements.
 
     The time namespace addresses this problem. It allows to set offsets for
     clock MONOTONIC and BOOTTIME once after creation and before tasks are
     associated with the namespace. These offsets are taken into account by
     timers and timekeeping including the VDSO.
 
     Offsets for wall clock based clocks (REALTIME/TAI) are not provided by
     this mechanism. While in theory possible, the overhead and code
     complexity would be immense and not justified by the esoteric potential
     use cases which were discussed at Plumbers '18.
 
     The overhead for tasks in the root namespace (host time offsets = 0) is
     in the noise and great effort was made to ensure that especially in the
     VDSO. If time namespace is disabled in the kernel configuration the
     code is compiled out.
 
     Kudos to Andrei Vagin and Dmitry Sofanov who implemented this feature
     and kept on for more than a year addressing review comments, finding
     better solutions. A pleasant experience.
 
   - Overhaul of the alarmtimer device dependency handling to ensure that
     the init/suspend/resume ordering is correct.
 
   - A new clocksource/event driver for Microchip PIT64
 
   - Suspend/resume support for the Hyper-V clocksource
 
   - The usual pile of fixes, updates and improvements mostly in the
     driver code.

Merge tag 'selinux-pr-20200127' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux

Pull SELinux update from Paul Moore:
 "This is one of the bigger SELinux pull requests in recent years with
  28 patches. Everything is passing our test suite and the highlights
  are below:

   - Mark CONFIG_SECURITY_SELINUX_DISABLE as deprecated. We're some time
     away from actually attempting to remove this in the kernel, but the
     only distro we know that still uses it (Fedora) is working on
     moving away from this so we want to at least let people know we are
     planning to remove it.

   - Reorder the SELinux hooks to help prevent bad things when SELinux
     is disabled at runtime. The proper fix is to remove the
     CONFIG_SECURITY_SELINUX_DISABLE functionality (see above) and just
     take care of it at boot time (e.g. "selinux=0").

   - Add SELinux controls for the kernel lockdown functionality,
     introducing a new SELinux class/permissions: "lockdown { integrity
     confidentiality }".

   - Add a SELinux control for move_mount(2) that reuses the "file {
     mounton }" permission.

   - Improvements to the SELinux security label data store lookup
     functions to speed up translations between our internal label
     representations and the visible string labels (both directions).

   - Revisit a previous fix related to SELinux inode auditing and
     permission caching and do it correctly this time.

   - Fix the SELinux access decision cache to cleanup properly on error.
     In some extreme cases this could limit the cache size and result in
     a decrease in performance.

   - Enable SELinux per-file labeling for binderfs.

   - The SELinux initialized and disabled flags were wrapped with
     accessors to ensure they are accessed correctly.

   - Mark several key SELinux structures with __randomize_layout.

   - Changes to the LSM build configuration to only build
     security/lsm_audit.c when needed.

   - Changes to the SELinux build configuration to only build the IB
     object cache when CONFIG_SECURITY_INFINIBAND is enabled.

   - Move a number of single-caller functions into their callers.

   - Documentation fixes (/selinux -> /sys/fs/selinux).

   - A handful of cleanup patches that aren't worth mentioning on their
     own, the individual descriptions have plenty of detail"

Linus Torvalds aae1464f46 regulator: Updates for v5.6
Hardly anything going on in the core this time around with the regulator
 API and pretty quiet on the driver front:
 
  - An API for comparing regulators, useful for devices that need to
    check if supply voltages exactly match rather than just nominally
    match.
  - Conversion of several DT bindings to YAML format.
  - Conversion of I2C drivers to probe_new().
  - New drivers for Monolithic MPQ7920 and MP8859, and Rohm BD71828.

Linus Torvalds 0238d3c753 arm64 updates for 5.6
- New architecture features
 	* Support for Armv8.5 E0PD, which benefits KASLR in the same way as
 	  KPTI but without the overhead. This allows KPTI to be disabled on
 	  CPUs that are not affected by Meltdown, even is KASLR is enabled.
 
 	* Initial support for the Armv8.5 RNG instructions, which claim to
 	  provide access to a high bandwidth, cryptographically secure hardware
 	  random number generator. As well as exposing these to userspace, we
 	  also use them as part of the KASLR seed and to seed the crng once
 	  all CPUs have come online.
 
 	* Advertise a bunch of new instructions to userspace, including support
 	  for Data Gathering Hint, Matrix Multiply and 16-bit floating point.
 
 - Kexec
 	* Cleanups in preparation for relocating with the MMU enabled
 	* Support for loading crash dump kernels with kexec_file_load()
 
 - Perf and PMU drivers
 	* Cleanups and non-critical fixes for a couple of system PMU drivers
 
 - FPU-less (aka broken) CPU support
 	* Considerable fixes to support CPUs without the FP/SIMD extensions,
 	  including their presence in heterogeneous systems. Good luck finding
 	  a 64-bit userspace that handles this.
 
 - Modern assembly function annotations
 	* Start migrating our use of ENTRY() and ENDPROC() over to the
 	  new-fangled SYM_{CODE,FUNC}_{START,END} macros, which are intended to
 	  aid debuggers
 
 - Kbuild
 	* Cleanup detection of LSE support in the assembler by introducing
 	  'as-instr'
 
 	* Remove compressed Image files when building clean targets
 
 - IP checksumming
 	* Implement optimised IPv4 checksumming routine when hardware offload
 	  is not in use. An IPv6 version is in the works, pending testing.
 
 - Hardware errata
 	* Work around Cortex-A55 erratum #1530923
 
 - Shadow call stack
 	* Work around some issues with Clang's integrated assembler not liking
 	  our perfectly reasonable assembly code
 
 	* Avoid allocating the X18 register, so that it can be used to hold the
 	  shadow call stack pointer in future
 
 - ACPI
 	* Fix ID count checking in IORT code. This may regress broken firmware
 	  that happened to work with the old implementation, in which case we'll
 	  have to revert it and try something else
 
 	* Fix DAIF corruption on return from GHES handler with pseudo-NMIs
 
 - Miscellaneous
 	* Whitelist some CPUs that are unaffected by Spectre-v2
 
 	* Reduce frequency of ASID rollover when KPTI is compiled in but
 	  inactive
 
 	* Reserve a couple of arch-specific PROT flags that are already used by
 	  Sparc and PowerPC and are planned for later use with BTI on arm64
 
 	* Preparatory cleanup of our entry assembly code in preparation for
 	  moving more of it into C later on
 
 	* Refactoring and cleanup

Pull arm64 updates from Will Deacon:
 "The changes are a real mixed bag this time around.

  The only scary looking one from the diffstat is the uapi change to
  asm-generic/mman-common.h, but this has been acked by Arnd and is
  actually just adding a pair of comments in an attempt to prevent
  allocation of some PROT values which tend to get used for
  arch-specific purposes. We'll be using them for Branch Target
  Identification (a CFI-like hardening feature), which is currently
  under review on the mailing list.
