      Fix up MAINTAINERS file sorting · 3882a734
      Linus Torvalds authored
      Another merge window, another MAINTAINERS file disaster.
      
      People have serious problems with the alphabet and sorting, and poor
      Jérôme Glisse and Radim Krčmář get their names mangled by locale issues,
      turning them into some mangled mess (probably others do too, but those
      two stood out when sorting things again).
      
      And we now have two copies of the same 'AS3645A LED FLASH CONTROLLER
      DRIVER' in the tree and in the MAINTAINERS file, but that's a separate
      issue - the duplication is real, and I left them as two entries for the
      same name.
      
      This does not try to sort the actual section pattern entries, although I
      may end up doing that later.

       "The diff is dominated by the Allwinner A10/A20 SoCs getting converted
        to the sunxi-ng framework. Otherwise, the heavy hitters are various

        some other new clk drivers in here too but overall this is just a
        bunch of clk drivers for various different pieces of hardware and a
        collection of non-critical fixes for clk drivers.

      xfs: XFS_IS_REALTIME_INODE() should be false if no rt device present · b31ff3cd
      Richard Wareing authored
      If using a kernel with CONFIG_XFS_RT=y and we set the RHINHERIT flag on
      a directory in a filesystem that does not have a realtime device and
      create a new file in that directory, it gets marked as a real time file.
      When data is written and a fsync is issued, the filesystem attempts to
      flush a non-existent rt device during the fsync process.
      
      This results in a crash dereferencing a null buftarg pointer in
      xfs_blkdev_issue_flush():
      
        BUG: unable to handle kernel NULL pointer dereference at 0000000000000008
        IP: xfs_blkdev_issue_flush+0xd/0x20
        .....
        Call Trace:
          xfs_file_fsync+0x188/0x1c0
          vfs_fsync_range+0x3b/0xa0
          do_fsync+0x3d/0x70
          SyS_fsync+0x10/0x20
          do_syscall_64+0x4d/0xb0
          entry_SYSCALL64_slow_path+0x25/0x25
      
      Setting RT inode flags does not require special privileges so any
      unprivileged user can cause this oops to occur.  To reproduce, confirm
      kernel is compiled with CONFIG_XFS_RT=y and run:
      
        # mkfs.xfs -f /dev/pmem0
        # mount /dev/pmem0 /mnt/test
        # mkdir /mnt/test/foo
        # xfs_io -c 'chattr +t' /mnt/test/foo
        # xfs_io -f -c 'pwrite 0 5m' -c fsync /mnt/test/foo/bar
      
      Or just run xfstests with MKFS_OPTIONS="-d rtinherit=1" and wait.
      
      Kernels built with CONFIG_XFS_RT=n are not exposed to this bug.

      f2fs: hurry up to issue discard after io interruption · e6c6de18
      Chao Yu authored
      Once we encounter I/O interruption during issuing discards, we will delay
      long time before next round, but if system status is I/O idle during the
      time, it may loses opportunity to issue discards. So this patch changes
      to hurry up to issue discard after io interruption.
      
      Besides, this patch also fixes to issue discards accurately with assigned
      rate.

      ovl: fix false positive ESTALE on lookup · 939ae4ef
      Amir Goldstein authored
      Commit b9ac5c27 ("ovl: hash overlay non-dir inodes by copy up origin")
      verifies that the origin lower inode stored in the overlayfs inode matched
      the inode of a copy up origin dentry found by lookup.
      
      There is a false positive result in that check when lower fs does not
      support file handles and copy up origin cannot be followed by file handle
      at lookup time.
      
      The false negative happens when finding an overlay inode in cache on a
      copied up overlay dentry lookup. The overlay inode still 'remembers' the
      copy up origin inode, but the copy up origin dentry is not available for
      verification.
      
      Relax the check in case copy up origin dentry is not available.

      fuse: allow server to run in different pid_ns · 5d6d3a30
      Miklos Szeredi authored
      Commit 0b6e9ea0 ("fuse: Add support for pid namespaces") broke
      Sandstorm.io development tools, which have been sending FUSE file
      descriptors across PID namespace boundaries since early 2014.
      
      The above patch added a check that prevented I/O on the fuse device file
      descriptor if the pid namespace of the reader/writer was different from the
      pid namespace of the mounter.  With this change passing the device file
      descriptor to a different pid namespace simply doesn't work.  The check was
      added because pids are transferred to/from the fuse userspace server in the
      namespace registered at mount time.
      
      To fix this regression, remove the checks and do the following:
      
      1) the pid in the request header (the pid of the task that initiated the
      filesystem operation) is translated to the reader's pid namespace.  If a
      mapping doesn't exist for this pid, then a zero pid is used.  Note: even if
      a mapping would exist between the initiator task's pid namespace and the
      reader's pid namespace the pid will be zero if either mapping from
      initator's to mounter's namespace or mapping from mounter's to reader's
      namespace doesn't exist.
      
      2) The lk.pid value in setlk/setlkw requests and getlk reply is left alone.
      Userspace should not interpret this value anyway.  Also allow the
      setlk/setlkw operations if the pid of the task cannot be represented in the
      mounter's namespace (pid being zero in that case).

      f2fs: clear radix tree dirty tag of pages whose dirty flag is cleared · 0abd8e70
      Daeho Jeong authored
      On a senario like writing out the first dirty page of the inode
      as the inline data, we only cleared dirty flags of the pages, but
      didn't clear the dirty tags of those pages in the radix tree.
      
      If we don't clear the dirty tags of the pages in the radix tree, the
      inodes which contain the pages will be marked with I_DIRTY_PAGES again
      and again, and writepages() for the inodes will be invoked in every
      writeback period. As a result, nothing will be done in every
      writepages() for the inodes and it will just consume CPU time
      meaninglessly.

      Pull namespace updates from Eric Biederman:
       "Life has been busy and I have not gotten half as much done this round
        as I would have liked. I delayed it so that a minor conflict
        resolution with the mips tree could spend a little time in linux-next
        before I sent this pull request.
      
        This includes two long delayed user namespace changes from Kirill
        Tkhai. It also includes a very useful change from Serge Hallyn that
        allows the security capability attribute to be used inside of user
        namespaces. The practical effect of this is people can now untar
        tarballs and install rpms in user namespaces. It had been suggested to
        generalize this and encode some of the namespace information
        information in the xattr name. Upon close inspection that makes the
        things that should be hard easy and the things that should be easy
        more expensive.
      
        Then there is my bugfix/cleanup for signal injection that removes the
        magic encoding of the siginfo union member from the kernel internal
        si_code. The mips folks reported the case where I had used FPE_FIXME
        me is impossible so I have remove FPE_FIXME from mips, while at the
        same time including a return statement in that case to keep gcc from
        complaining about unitialized variables.
      
        I almost finished the work to get make copy_siginfo_to_user a trivial
        copy to user. The code is available at:
      
           git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git neuter-copy_siginfo_to_user-v3
      
        But I did not have time/energy to get the code posted and reviewed
        before the merge window opened.
      
        I was able to see that the security excuse for just copying fields
        that we know are initialized doesn't work in practice there are buggy
        initializations that don't initialize the proper fields in siginfo. So
        we still sometimes copy unitialized data to userspace"

      block: directly insert blk-mq request from blk_insert_cloned_request() · 157f377b
      Jens Axboe authored
      A NULL pointer crash was reported for the case of having the BFQ IO
      scheduler attached to the underlying blk-mq paths of a DM multipath
      device.  The crash occured in blk_mq_sched_insert_request()'s call to
      e->type->ops.mq.insert_requests().
      
      Paolo Valente correctly summarized why the crash occured with:
      "the call chain (dm_mq_queue_rq -> map_request -> setup_clone ->
      blk_rq_prep_clone) creates a cloned request without invoking
      e->type->ops.mq.prepare_request for the target elevator e.  The cloned
      request is therefore not initialized for the scheduler, but it is
      however inserted into the scheduler by blk_mq_sched_insert_request."
      
      All said, a request-based DM multipath device's IO scheduler should be
      the only one used -- when the original requests are issued to the
      underlying paths as cloned requests they are inserted directly in the
      underlying dispatch queue(s) rather than through an additional elevator.
      
      But commit bd166ef1 ("blk-mq-sched: add framework for MQ capable IO
      schedulers") switched blk_insert_cloned_request() from using
      blk_mq_insert_request() to blk_mq_sched_insert_request().  Which
      incorrectly added elevator machinery into a call chain that isn't
      supposed to have any.
      
      To fix this introduce a blk-mq private blk_mq_request_bypass_insert()
      that blk_insert_cloned_request() calls to insert the request without
      involving any elevator that may be attached to the cloned request's
      request_queue.
