      CIFS: Fix build failure with smb2 · 4fa8e504
      Tobias Regnery authored
      I saw the following build error during a randconfig build:
      
      fs/cifs/smb2ops.c: In function 'smb2_new_lease_key':
      fs/cifs/smb2ops.c:1104:2: error: implicit declaration of function 'generate_random_uuid' [-Werror=implicit-function-declaration]
      
      Explicit include the right header to fix this issue.

      Introduce cifs_copy_file_range() · 620d8745
      Sachin Prabhu authored
      The earlier changes to copy range for cifs unintentionally disabled the more
      common form of server side copy.
      
      The patch introduces the file_operations helper cifs_copy_file_range()
      which is used by the syscall copy_file_range. The new file operations
      helper allows us to perform server side copies for SMB2.0 and 2.1
      servers as well as SMB 3.0+ servers which do not support the ioctl
      FSCTL_DUPLICATE_EXTENTS_TO_FILE.
      
      The new helper uses the ioctl FSCTL_SRV_COPYCHUNK_WRITE to perform
      server side copies. The helper is called by vfs_copy_file_range() only
      once an attempt to clone the file using the ioctl
      FSCTL_DUPLICATE_EXTENTS_TO_FILE has failed.

      SMB3: Rename clone_range to copychunk_range · 312bbc59
      Sachin Prabhu authored
      Server side copy is one of the most important mechanisms smb2/smb3
      supports and it was unintentionally disabled for most use cases.
      
      Renaming calls to reflect the underlying smb2 ioctl called. This is
      similar to the name duplicate_extents used for a similar ioctl which is
      also used to duplicate files by reusing fs blocks. The name change is to
      avoid confusion.

      Handle mismatched open calls · 38bd4906
      Sachin Prabhu authored
      A signal can interrupt a SendReceive call which result in incoming
      responses to the call being ignored. This is a problem for calls such as
      open which results in the successful response being ignored. This
      results in an open file resource on the server.
      
      The patch looks into responses which were cancelled after being sent and
      in case of successful open closes the open fids.
      
      For this patch, the check is only done in SendReceive2()

       "Here are three more fixes for 4.11.
      
        The first one reworks the inline directory verifier to check the
        working copy of the directory metadata and to avoid triggering a
        periodic crash in xfs/348. The second patch fixes a regression in hole
        punching at EOF that corrupts files; and the third patch closes a
        kernel memory disclosure bug.
      
        Summary:
      
         - rework the inline directory verifier to avoid crashes on disk
           corruption
      
         - don't change file size when punching holes w/ KEEP_SIZE
      
         - close a kernel memory exposure bug"

      We should unregister the net_device first, before we give back

      tcp: fix reordering SNMP under-counting · 2d2517ee
      Yuchung Cheng authored
      Currently the reordering SNMP counters only increase if a connection
      sees a higher degree then it has previously seen. It ignores if the
      reordering degree is not greater than the default system threshold.
      This significantly under-counts the number of reordering events
      and falsely convey that reordering is rare on the network.
      
      This patch properly and faithfully records the number of reordering
      events detected by the TCP stack, just like the comment says "this
      exciting event is worth to be remembered". Note that even so TCP
      still under-estimate the actual reordering events because TCP
      requires TS options or certain packet sequences to detect reordering
      (i.e. ACKing never-retransmitted sequence in recovery or disordered
       state).
