      smb3: fix cached file size problems in duplicate extents (reflink) · cfc63fc8
      Steve French authored
      
      
      There were two problems (one of which could cause data corruption)
      that were noticed with duplicate extents (ie reflink)
      when debugging why various xfstests were being incorrectly skipped
      (e.g. generic/138, generic/140, generic/142). First, we were not
      updating the file size locally in the cache when extending a
      file due to reflink (it would refresh after actimeo expires)
      but xfstest was checking the size immediately which was still
      0 so caused the test to be skipped.  Second, we were setting
      the target file size (which could shrink the file) in all cases
      to the end of the reflinked range rather than only setting the
      target file size when reflink would extend the file.

      cifs: Silently ignore unknown oplock break handle · 219481a8
      Vincent Whitchurch authored
      
      
      Make SMB2 not print out an error when an oplock break is received for an
      unknown handle, similar to SMB1.  The debug message which is printed for
      these unknown handles may also be misleading, so fix that too.
      
      The SMB2 lease break path is not affected by this patch.
      
      Without this, a program which writes to a file from one thread, and
      opens, reads, and writes the same file from another thread triggers the
      below errors several times a minute when run against a Samba server

      cifs: revalidate mapping when we open files for SMB1 POSIX · cee8f4f6
      Ronnie Sahlberg authored
      
      
      RHBZ: 1933527
      
      Under SMB1 + POSIX, if an inode is reused on a server after we have read and
      cached a part of a file, when we then open the new file with the
      re-cycled inode there is a chance that we may serve the old data out of cache
      to the application.
      This only happens for SMB1 (deprecated) and when posix are used.
      The simplest solution to avoid this race is to force a revalidate
      on smb1-posix open.

      kernel: don't call do_exit() for PF_IO_WORKER threads · 10442994
      Jens Axboe authored
      
      
      Right now we're never calling get_signal() from PF_IO_WORKER threads, but
      in preparation for doing so, don't handle a fatal signal for them. The
      workers have state they need to cleanup when exiting, so just return
      instead of calling do_exit() on their behalf. The threads themselves will
      detect a fatal signal and do proper shutdown.

      dm ioctl: fix out of bounds array access when no devices · 4edbe1d7
      Mikulas Patocka authored
      
      
      If there are not any dm devices, we need to zero the "dev" argument in
      the first structure dm_name_list. However, this can cause out of
      bounds write, because the "needed" variable is zero and len may be
      less than eight.
      
      Fix this bug by reporting DM_BUFFER_FULL_FLAG if the result buffer is
      too small to hold the "nl->dev" value.
