      Pull safesetid updates from Micah Morton:
       "These changes from Jann Horn fix a couple issues in the recently added
        SafeSetID LSM:
      
         - There was a simple logic bug in one of the hooks for the LSM where
           the code was incorrectly returning early in some cases before all
           security checks had been passed.
      
         - There was a more high level issue with how this LSM gets configured
           that could allow for a program to bypass the security restrictions
           by switching to an allowed UID and then again to any other UID on
           the system if the target UID of the first transition is
           unconstrained on the system. Luckily this is an easy fix that we
           now enforce at the time the LSM gets configured.
      
        There are also some changes from Jann that make policy updates for
        this LSM atomic. Kees Cook, Jann and myself have reviewed these
        changes and they look good from our point of view"

      Pull pidfd and clone3 fixes from Christian Brauner:
       "This contains a bugfix for CLONE_PIDFD when used with the legacy clone
        syscall, two fixes to ensure that syscall numbering and clone3
        entrypoint implementations will stay consistent, and an update for the
        maintainers file:
      
         - The addition of clone3 broke CLONE_PIDFD for legacy clone on all
           architectures that use do_fork() directly instead of calling the
           clone syscall itself. (Fwiw, cleaning do_fork() up is on my todo.)
      
           The reason this happened was that during conversion of _do_fork()
           to use struct kernel_clone_args we missed that do_fork() is called
           directly by various architectures. This is fixed by making sure
           that the pidfd argument in struct kernel_clone_args is correctly
           initialized with the parent_tidptr argument passed down from
           do_fork(). Additionally, do_fork() missed a check to make
           CLONE_PIDFD and CLONE_PARENT_SETTID mutually exclusive just a
           clone() does. This is now fixed too.
      
         - When clone3() was introduced we skipped architectures that require
           special handling for fork-like syscalls. Their syscall tables did
           not contain any mention of clone3().
      
           To make sure that Arnd's work to make syscall numbers on all
           architectures identical (minus alpha) was not for naught we are
           placing a comment in all syscall tables that do not yet implement
           clone3(). The comment makes it clear that 435 is reserved for
           clone3 and should not be used.
      
         - Also, this contains a patch to make the clone3() syscall definition
           in asm-generic/unist.h conditional on __ARCH_WANT_SYS_CLONE3. This
           lets us catch new architectures that implicitly make use of clone3
           without setting __ARCH_WANT_SYS_CLONE3 which is a good indicator
           that they did not check whether it needs special treatment or not.
      
         - Finally, this contains a patch to add me as maintainer for pidfd
           stuff so people can start blaming me (more)"

      Merge branch 'proc-cmdline' (/proc/<pid>/cmdline fixes) · 29541522
      Linus Torvalds authored
      This fixes two problems reported with the cmdline simplification and
      cleanup last year:
      
       - the setproctitle() special cases didn't quite match the original
         semantics, and it can be noticeable:
      
            https://lore.kernel.org/lkml/alpine.LNX.2.21.1904052326230.3249@kich.toxcorp.com/
      
       - it could leak an uninitialized byte from the temporary buffer under
         the right (wrong) circustances:
      
            https://lore.kernel.org/lkml/20190712160913.17727-1-izbyshev@ispras.ru/
      
      It rewrites the logic entirely, splitting it into two separate commits
      (and two separate functions) for the two different cases ("unedited
      cmdline" vs "setproctitle() has been used to change the command line").
      
      * proc-cmdline:
        /proc/<pid>/cmdline: add back the setproctitle() special case
        /proc/<pid>/cmdline: remove all the special cases

      /proc/<pid>/cmdline: add back the setproctitle() special case · d26d0cd9
      Linus Torvalds authored
      This makes the setproctitle() special case very explicit indeed, and
      handles it with a separate helper function entirely.  In the process, it
      re-instates the original semantics of simply stopping at the first NUL
      character when the original last NUL character is no longer there.
      
      [ The original semantics can still be seen in mm/util.c: get_cmdline()
        that is limited to a fixed-size buffer ]
      
      This makes the logic about when we use the string lengths etc much more
      obvious, and makes it easier to see what we do and what the two very
      different cases are.
      
      Note that even when we allow walking past the end of the argument array
      (because the setproctitle() might have overwritten and overflowed the
      original argv[] strings), we only allow it when it overflows into the
      environment region if it is immediately adjacent.
      
      [ Fixed for missing 'count' checks noted by Alexey Izbyshev ]

      /proc/<pid>/cmdline: remove all the special cases · 3d712546
      Linus Torvalds authored
      Start off with a clean slate that only reads exactly from arg_start to
      arg_end, without any oddities.  This simplifies the code and in the
      process removes the case that caused us to potentially leak an
      uninitialized byte from the temporary kernel buffer.
      
      Note that in order to start from scratch with an understandable base,
      this simplifies things _too_ much, and removes all the legacy logic to
      handle setproctitle() having changed the argument strings.
      
      We'll add back those special cases very differently in the next commit.

      LSM: SafeSetID: verify transitive constrainedness · 4f72123d
      Jann Horn authored
      Someone might write a ruleset like the following, expecting that it
      securely constrains UID 1 to UIDs 1, 2 and 3:
      
          1:2
          1:3
      
      However, because no constraints are applied to UIDs 2 and 3, an attacker
      with UID 1 can simply first switch to UID 2, then switch to any UID from
      there. The secure way to write this ruleset would be:
      
          1:2
          1:3
          2:2
          3:3
      
      , which uses "transition to self" as a way to inhibit the default-allow
      policy without allowing anything specific.
      
      This is somewhat unintuitive. To make sure that policy authors don't
      accidentally write insecure policies because of this, let the kernel verify
      that a new ruleset does not contain any entries that are constrained, but
      transitively unconstrained.

      LSM: SafeSetID: rewrite userspace API to atomic updates · 03638e62
      Jann Horn authored
      The current API of the SafeSetID LSM uses one write() per rule, and applies
      each written rule instantly. This has several downsides:
      
       - While a policy is being loaded, once a single parent-child pair has been
         loaded, the parent is restricted to that specific child, even if
         subsequent rules would allow transitions to other child UIDs. This means
         that during policy loading, set*uid() can randomly fail.
       - To replace the policy without rebooting, it is necessary to first flush
         all old rules. This creates a time window in which no constraints are
         placed on the use of CAP_SETUID.
       - If we want to perform sanity checks on the final policy, this requires
         that the policy isn't constructed in a piecemeal fashion without telling
         the kernel when it's done.
      
      Other kernel APIs - including things like the userns code and netfilter -
      avoid this problem by performing updates atomically. Luckily, SafeSetID
      hasn't landed in a stable (upstream) release yet, so maybe it's not too
      late to completely change the API.
      
      The new API for SafeSetID is: If you want to change the policy, open
      "safesetid/whitelist_policy" and write the entire policy,
      newline-delimited, in there.

      Looking at current_cred() in write handlers is bad form, stop doing that.
      
      Also, let's just require that the write is coming from the initial user
      namespace. Especially SAFESETID_WHITELIST_FLUSH requires privilege over all
      namespaces, and SAFESETID_WHITELIST_ADD should probably require it as well.

      (1,1,1) calls setresuid(2,3,4), safesetid_task_fix_setuid() only checks
      whether the transition 1->2 is permitted; the transitions 1->3 and 1->4 are
      not checked. Fix this.
      
      This is also a good opportunity to refactor safesetid_task_fix_setuid() to
      be less verbose - having one branch per set*uid() syscall is unnecessary.
      
      Note that this slightly changes semantics: The UID transition check for
      UIDs that were not in the old cred struct is now always performed against
      the policy of the RUID. I think that's more consistent anyway, since the
      RUID is also the one that decides whether any policy is enforced at all.

      LSM: SafeSetID: fix pr_warn() to include newline · c783d525
      Jann Horn authored
      Fix the pr_warn() calls in the SafeSetID LSM to have newlines at the end.
      Without this, denial messages will be buffered as incomplete lines in
      log_output(), and will then only show up once something else prints into
      dmesg.

           nouveau to be using this API.
      
         - Remove old or transitional hmm APIs. These are hold overs from the
           past with no users, or APIs that existed only to manage cross tree
           conflicts. There are still a few more of these cleanups that didn't
           make the merge window cut off.
      
         - Improve some core mm APIs:
             - export alloc_pages_vma() for driver use
             - refactor into devm_request_free_mem_region() to manage
               DEVICE_PRIVATE resource reservations
             - refactor duplicative driver code into the core dev_pagemap
               struct

      Pull stream_open() updates from Kirill Smelkov:
       "This time on stream_open front it is only two small changes:
      
         - the first one converts stream_open.cocci to treat all functions
           that start with wait_.* as blocking. Previously it was only
           wait_event_.* functions that were considered as blocking, but this
           was falsely reporting several deadlock cases as only warning.
      
           This was picked by linux-kbuild and entered mainline as commit
           0c4ab18f ("coccinelle: api/stream_open: treat all wait_.*()
           calls as blocking"), and already merged earlier.
      
         - the second one teaches stream_open.cocci to consider files as being
           stream-like even if they use noop_llseek. It results in two more
           drivers being converted to stream_open() (mousedev.c and

      Pull x86 platform driver updates from Andy Shevchenko:
       "Gathered a bunch of x86 platform driver changes. It's rather big,
        since includes two big refactors and completely new driver:
      
         - ASUS WMI driver got a big refactoring in order to support the TUF
           Gaming laptops. Besides that, the regression with backlight being
           permanently off on various EeePC laptops has been fixed.
      
         - Accelerometer on HP ProBook 450 G0 shows wrong measurements due to
           X axis being inverted. This has been fixed.
      
         - Intel PMC core driver has been extended to be ACPI enumerated if
           the DSDT provides device with _HID "INT33A1". This allows to
           convert the driver to be pure platform and support new hardware
           purely based on ACPI DSDT.
      
         - From now on the Intel Speed Select Technology is supported thru a
           corresponding driver. This driver provides an access to the
           features of the ISST, such as Performance Profile, Core Power, Base
           frequency and Turbo Frequency.
      
         - Mellanox platform drivers has been refactored and now extended to
           support more systems, including new coming ones.
      
         - The OLPC XO-1.75 platform is now supported.
      
         - CB4063 Beckhoff Automation board is using PMC clocks, provided via
           pmc_atom driver, for ethernet controllers in a way that they can't
           be managed by the clock driver. The quirk has been extended to
           cover this case.
      
         - Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile
           the information of Chuwi Hi10 Air has been fixed to cover more
           models based on the same platform.
      
         - Xiaomi notebooks have WMI interface enabled. Thus, the driver to
           support it has been provided. It required some extension of the
           generic WMI library, which allows to propagate opaque context to
           the ->probe() of the individual drivers.
      
        This release includes debugfs clean up from Greg KH for several
        drivers that drop return code check and make debugfs absence or
        failure non-fatal.
      
        Also miscellaneous fixes here and there, mostly for Acer WMI and

      unistd: protect clone3 via __ARCH_WANT_SYS_CLONE3 · 05a70a8e
      Christian Brauner authored
      This lets us catch new architectures that implicitly make use of clone3
      without setting __ARCH_WANT_SYS_CLONE3.
      Failing on missing __ARCH_WANT_SYS_CLONE3 is a good indicator that they
      either did not really want this syscall or haven't really thought about
      whether it needs special treatment and just accidently included it in
      their entrypoints by e.g. generating their syscall table automatically
      via asm-generic/unistd.h
      
      This patch has been compile-tested for the h8300 architecture which is
      one of the architectures that does not yet implement clone3 and
      generates its syscall table via asm-generic/unistd.h.

      arch: mark syscall number 435 reserved for clone3 · 1a271a68
      Christian Brauner authored
      A while ago Arnd made it possible to give new system calls the same
      syscall number on all architectures (except alpha). To not break this
      nice new feature let's mark 435 for clone3 as reserved on all
      architectures that do not yet implement it.
      Even if an architecture does not plan to implement it this ensures that
      new system calls coming after clone3 will have the same number on all
      architectures.
