      Input: soc_button_array - fix mapping of the 5th GPIO in a PNP0C40 device · e9eb788f
      Hans de Goede authored
      The Microsoft documenation for the PNP0C40 device aka the
      "Windows-compatible button array" describes the 5th GpioInt listed in
      the resources as: '5. Interrupt corresponding to the "Rotation Lock"
      button, if supported'.
      
      Notice this describes the 5th entry as a button while we sofar have been
      mapping it to EV_SW, SW_ROTATE_LOCK. On my Point of View TAB P1006W-232
      which actually comes with a rotation-lock button, the button indeed is a
      button and not a slider/switch. An image search for other Windows tablets
      has found 2 more models with a rotation-lock button and on both of those
      it too is a push-button and not a slider/switch.
      
      Further evidence can be found in the HUT extension HUTRR52 from Microsoft
      which adds rotation lock support to the HUT, which describes 2 different
      usages: "0xC9 System Display Rotation Lock Button" and
      "0xCA System Display Rotation Lock Slider Switch" note that switch is seen
      as a separate thing here and the non switch wording is an exact match for
      the "Windows-compatible button array" spec wording.
      
      TL;DR: our current mapping of the 5th GPIO to SW_ROTATE_LOCK is wrong
      because the 5th GPIO is for a push-button not a switch.
      
      This commit fixes this by maping the 5th GPIO to KEY_ROTATE_LOCK_TOGGLE.

      Input: soc_button_array - add usage-page 0x01 usage-id 0xca mapping · 39be9b6d
      Hans de Goede authored
      The ACPI0011 _DSD button descriptor on a CHT based Intel Compute Sticks
      contains a mapping for usage-page 0x01 usage-id 0xca.
      
      As described in hutrr52_system_display_rotation_lock_controls_0.pdf this
      should be mapped as a "System Display Rotation Lock Slider Switch", this
      commit adds support for this, silencing the following warning:

      Revert "vfs: Allow userns root to call mknod on owned filesystems." · 94f82008
      Christian Brauner authored
      This reverts commit 55956b59.
      
      commit 55956b59 ("vfs: Allow userns root to call mknod on owned filesystems.")
      enabled mknod() in user namespaces for userns root if CAP_MKNOD is
      available. However, these device nodes are useless since any filesystem
      mounted from a non-initial user namespace will set the SB_I_NODEV flag on
      the filesystem. Now, when a device node s created in a non-initial user
      namespace a call to open() on said device node will fail due to:
      
      bool may_open_dev(const struct path *path)
      {
              return !(path->mnt->mnt_flags & MNT_NODEV) &&
                      !(path->mnt->mnt_sb->s_iflags & SB_I_NODEV);
      }
      
      The problem with this is that as of the aforementioned commit mknod()
      creates partially functional device nodes in non-initial user namespaces.
      In particular, it has the consequence that as of the aforementioned commit
      open() will be more privileged with respect to device nodes than mknod().
      Before it was the other way around. Specifically, if mknod() succeeded
      then it was transparent for any userspace application that a fatal error
      must have occured when open() failed.
      
      All of this breaks multiple userspace workloads and a widespread assumption
      about how to handle mknod(). Basically, all container runtimes and systemd
      live by the slogan "ask for forgiveness not permission" when running user
      namespace workloads. For mknod() the assumption is that if the syscall
      succeeds the device nodes are useable irrespective of whether it succeeds
      in a non-initial user namespace or not. This logic was chosen explicitly
      to allow for the glorious day when mknod() will actually be able to create
      fully functional device nodes in user namespaces.
      A specific problem people are already running into when running 4.18 rc
      kernels are failing systemd services. For any distro that is run in a
      container systemd services started with the PrivateDevices= property set
      will fail to start since the device nodes in question cannot be
      opened (cf. the arguments in [1]).
      
      Full disclosure, Seth made the very sound argument that it is already
      possible to end up with partially functional device nodes. Any filesystem
      mounted with MS_NODEV set will allow mknod() to succeed but will not allow
      open() to succeed. The difference to the case here is that the MS_NODEV
      case is transparent to userspace since it is an explicitly set mount option
      while the SB_I_NODEV case is an implicit property enforced by the kernel
      and hence opaque to userspace.

      The reason is we do not pass the Head to page_hstate(), and so, the call
      to compound_order() in page_hstate() returns 0, so we end up checking
      all hstates's size to match PAGE_SIZE.
      
      Obviously, we do not find any hstate matching that size, and we return
      NULL.  Then, we dereference that NULL pointer in
      hugepage_migration_supported() and we got the #PF from above.
      
      Fix that by getting the head page before calling page_hstate().
      
      Also, since gigantic pages span several pageblocks, re-adjust the logic
      for skipping pages.  While are it, we can also get rid of the
      round_up().

      fork,memcg: fix crash in free_thread_stack on memcg charge fail · 5eed6f1d
      Rik van Riel authored
      Commit 9b6f7e16 ("mm: rework memcg kernel stack accounting") will
      result in fork failing if allocating a kernel stack for a task in
      dup_task_struct exceeds the kernel memory allowance for that cgroup.
      
      Unfortunately, it also results in a crash.
      
      This is due to the code jumping to free_stack and calling
      free_thread_stack when the memcg kernel stack charge fails, but without
      tsk->stack pointing at the freshly allocated stack.
      
      This in turn results in the vfree_atomic in free_thread_stack oopsing
      with a backtrace like this:

      mm: thp: fix flags for pmd migration when split · 2e83ee1d
      Peter Xu authored
      When splitting a huge migrating PMD, we'll transfer all the existing PMD
      bits and apply them again onto the small PTEs.  However we are fetching
      the bits unconditionally via pmd_soft_dirty(), pmd_write() or
      pmd_yound() while actually they don't make sense at all when it's a
      migration entry.  Fix them up.  Since at it, drop the ifdef together as
      not needed.
      
      Note that if my understanding is correct about the problem then if
      without the patch there is chance to lose some of the dirty bits in the
      migrating pmd pages (on x86_64 we're fetching bit 11 which is part of
      swap offset instead of bit 2) and it could potentially corrupt the
      memory of an userspace program which depends on the dirty bit.

      auxdisplay: charlcd: fix x/y command parsing · 9bc30ab8
      Mans Rullgard authored
      The x/y command parsing has been broken since commit 12995706
      ("staging: panel: Fixed checkpatch warning about simple_strtoul()").
      
      Commit b34050fa ("auxdisplay: charlcd: Fix and clean up handling of
      x/y commands") fixed some problems by rewriting the parsing code,
      but also broke things further by removing the check for a complete
      command before attempting to parse it.  As a result, parsing is
      terminated at the first x or y character.
      
      This reinstates the check for a final semicolon.  Whereas the original
      code use strchr(), this is wasteful seeing as the semicolon is always
      at the end of the buffer.  Thus check this character directly instead.

      serial/sunsu: fix refcount leak · d430aff8
      Yangtao Li authored
      The function of_find_node_by_path() acquires a reference to the node
      returned by it and that reference needs to be dropped by its caller.
      
      su_get_type() doesn't do that. The match node are used as an identifier
      to compare against the current node, so we can directly drop the refcount
      after getting the node from the path as it is not used as pointer.
      
      Fix this by use a single variable and drop the refcount right after
      of_find_node_by_path().

      tls: Do not call sk_memcopy_from_iter with zero length · 65a10e28
      Vakul Garg authored
      In some conditions e.g. when tls_clone_plaintext_msg() returns -ENOSPC,
      the number of bytes to be copied using subsequent function
      sk_msg_memcopy_from_iter() becomes zero. This causes function
      sk_msg_memcopy_from_iter() to fail which in turn causes tls_sw_sendmsg()
      to return failure. To prevent it, do not call sk_msg_memcopy_from_iter()
      when number of bytes to copy (indicated by 'try_to_copy') is zero.

        fixing the underlying inliner weaknesses - so as time ran out we
        decided to do a reasonably straightforward revert of the patches. The
        plan is to rely on the 'asm inline' GCC 9 feature, which might be
        backported to GCC 8 and could thus become reasonably widely available
        on modern distros.
      
        Other than those reverts, there's misc fixes from all around the

      Prevent overflow of sk_msg in sk_msg_clone() · 5c1e7e94
      Vakul Garg authored
      Fixed function sk_msg_clone() to prevent overflow of 'dst' while adding
      pages in scatterlist entries. The overflow of 'dst' causes crash in kernel
      tls module while doing record encryption.
      
      Crash fixed by this patch.
