      hwmon: (ftsteutates) Fix potential memory access error · 4c8702b3
      Guenter Roeck authored
      Using set_bit() to set a bit in an integer is not a good idea, since
      the function expects an unsigned long as argument, which can be 64 bit
      wide. Coverity reports this problem as
      
      >>>     CID 1364488:  Memory - illegal accesses  (INCOMPATIBLE_CAST)
      >>>     Pointer "&ret" points to an object whose effective type is "int"
      >>>	(32 bits, signed) but is dereferenced as a wider "unsigned
      +long" (64 bits, unsigned).  This may lead to memory corruption.
      245                     set_bit(1, (unsigned long *)&ret);
      
      Just use BIT instead.

       "The majority of this update is about ASoC, including a few new
        drivers, and the rest are mostly minor changes.  The only substantial
        change in ALSA core is about the additional error handling in the
        compress-offload API.  Below are highlights:
      
         - Add the error propagating support in compress-offload API
      
         - HD-audio: a usual Dell headset fixup, an Intel HDMI/DP fix, and the
           default mixer setup change ot turn off the loopback
      
         - Lots of updates for ASoC Intel drivers, mostly board support and
           bug fixing, and to the NAU8825 driver
      
         - Work on generalizing bits of simple-card to allow more code sharing
           with the Renesas rsrc-card (which can't use simple-card due to DPCM)
      
         - Removal of the Odroid X2 driver due to replacement with simple-card
      
         - Support for several new Mediatek platforms and associated boards
      
         - New ASoC drivers for Allwinner A10, Analog Devices ADAU7002,
           Broadcom Cygnus, Cirrus Logic CS35L33 and CS53L30, Maxim MAX8960
           and MAX98504, Realtek RT5514 and Wolfson WM8758"

      random: Fix crashes with sparse node ids · dd0f0cf5
      Michael Ellerman authored
      On a system with sparse node ids, eg. a powerpc system with 4 nodes
      numbered like so:
      
        node   0: [mem 0x0000000000000000-0x00000007ffffffff]
        node   1: [mem 0x0000000800000000-0x0000000fffffffff]
        node  16: [mem 0x0000001000000000-0x00000017ffffffff]
        node  17: [mem 0x0000001800000000-0x0000001fffffffff]
      
      The code in rand_initialize() will allocate 4 pointers for the pool
      array, and initialise them correctly.
      
      However when go to use the pool, in eg. extract_crng(), we use the
      numa_node_id() to index into the array. For the higher numbered node ids
      this leads to random memory corruption, depending on what was kmalloc'ed
      adjacent to the pool array.
      
      Fix it by using nr_node_ids to size the pool array.
      
      Fixes: 1e7f583a ("random: make /dev/urandom scalable for silly userspace programs")

      Pull NFS client updates from Trond Myklebust:
       "Highlights include:
      
        Stable bugfixes:
         - nfs: don't create zero-length requests
      
         - several LAYOUTGET bugfixes
      
        Features:
         - several performance related features
      
         - more aggressive caching when we can rely on close-to-open
           cache consistency
      
         - remove serialisation of O_DIRECT reads and writes
      
         - optimise several code paths to not flush to disk unnecessarily.
      
           However allow for the idiosyncracies of pNFS for those layout
           types that need to issue a LAYOUTCOMMIT before the metadata can
           be updated on the server.
      
         - SUNRPC updates to the client data receive path
      
         - pNFS/SCSI support RH/Fedora dm-mpath device nodes
      
         - pNFS files/flexfiles can now use unprivileged ports when
           the generic NFS mount options allow it.
      
        Bugfixes:
         - Don't use RDMA direct data placement together with data
           integrity or privacy security flavours
      
         - Remove the RDMA ALLPHYSICAL memory registration mode as
           it has potential security holes.
      
         - Several layout recall fixes to improve NFSv4.1 protocol
           compliance.
      
         - Fix an Oops in the pNFS files and flexfiles connection
           setup to the DS
      
         - Allow retry of operations that used a returned delegation
            stateid
      
         - Don't mark the inode as revalidated if a LAYOUTCOMMIT is
           outstanding

      Pull userns vfs updates from Eric Biederman:
       "This tree contains some very long awaited work on generalizing the
        user namespace support for mounting filesystems to include filesystems
        with a backing store.  The real world target is fuse but the goal is
        to update the vfs to allow any filesystem to be supported.  This
        patchset is based on a lot of code review and testing to approach that
        goal.
      
        While looking at what is needed to support the fuse filesystem it
        became clear that there were things like xattrs for security modules
        that needed special treatment.  That the resolution of those concerns
        would not be fuse specific.  That sorting out these general issues
        made most sense at the generic level, where the right people could be
        drawn into the conversation, and the issues could be solved for
        everyone.
      
        At a high level what this patchset does a couple of simple things:
      
         - Add a user namespace owner (s_user_ns) to struct super_block.
      
         - Teach the vfs to handle filesystem uids and gids not mapping into
           to kuids and kgids and being reported as INVALID_UID and
           INVALID_GID in vfs data structures.
      
        By assigning a user namespace owner filesystems that are mounted with
        only user namespace privilege can be detected.  This allows security
        modules and the like to know which mounts may not be trusted.  This
        also allows the set of uids and gids that are communicated to the
        filesystem to be capped at the set of kuids and kgids that are in the
        owning user namespace of the filesystem.
      
        One of the crazier corner casees this handles is the case of inodes
        whose i_uid or i_gid are not mapped into the vfs.  Most of the code
        simply doesn't care but it is easy to confuse the inode writeback path
        so no operation that could cause an inode write-back is permitted for
        such inodes (aka only reads are allowed).
      
        This set of changes starts out by cleaning up the code paths involved
        in user namespace permirted mounts.  Then when things are clean enough
        adds code that cleanly sets s_user_ns.  Then additional restrictions
        are added that are possible now that the filesystem superblock
        contains owner information.
      
        These changes should not affect anyone in practice, but there are some
        parts of these restrictions that are changes in behavior.
      
         - Andy's restriction on suid executables that does not honor the
           suid bit when the path is from another mount namespace (think
           /proc/[pid]/fd/) or when the filesystem was mounted by a less
           privileged user.
      
         - The replacement of the user namespace implicit setting of MNT_NODEV
           with implicitly setting SB_I_NODEV on the filesystem superblock
           instead.
      
           Using SB_I_NODEV is a stronger form that happens to make this state
           user invisible.  The user visibility can be managed but it caused
           problems when it was introduced from applications reasonably
           expecting mount flags to be what they were set to.
      
        There is a little bit of work remaining before it is safe to support
        mounting filesystems with backing store in user namespaces, beyond
        what is in this set of changes.
      
         - Verifying the mounter has permission to read/write the block device
           during mount.
      
         - Teaching the integrity modules IMA and EVM to handle filesystems
           mounted with only user namespace root and to reduce trust in their
           security xattrs accordingly.
      
         - Capturing the mounters credentials and using that for permission
           checks in d_automount and the like.  (Given that overlayfs already
           does this, and we need the work in d_automount it make sense to
           generalize this case).
      
        Furthermore there are a few changes that are on the wishlist:
      
         - Get all filesystems supporting posix acls using the generic posix
           acls so that posix_acl_fix_xattr_from_user and
           posix_acl_fix_xattr_to_user may be removed.  [Maintainability]
      
         - Reducing the permission checks in places such as remount to allow
           the superblock owner to perform them.
      
         - Allowing the superblock owner to chown files with unmapped uids and
           gids to something that is mapped so the files may be treated
           normally.
      
        I am not considering even obvious relaxations of permission checks
        until it is clear there are no more corner cases that need to be
        locked down and handled generically.
      
        Many thanks to Seth Forshee who kept this code alive, and putting up
        with me rewriting substantial portions of what he did to handle more
        corner cases, and for his diligent testing and reviewing of my
        changes"

      documentation: da9052: Update regulator bindings names to match DA9052/53 DTS expectations · 099c0cbd
      Steve Twiss authored
      Buck and LDO binding name changes.
      
      The binding names for the regulators have been changed to match the current
      expectation from existing device tree source files.
      
      This fix rectifies the disparity between what currently exists in some
      .dts[i] board files and what is listed in this binding document. This
      change re-aligns those differences and also brings the binding document
      in-line with the expectations of the product datasheet from Dialog
      Semiconductor.
      
      Bucks and LDOs now follow the expected notation:
      { buck1, buck2, buck3, buck4 }
      { ldo1, ldo2, ldo3, ldo4, ldo5, ldo6, ldo7, ldo8, ldo9, ldo10 }
