      NTB: Fix zero size or integer overflow in ntb_set_mw · 8c9edf63
      Allen Hubbe authored
      A plain 32 bit integer will overflow for values over 4GiB.
      
      Change the plain integer size to the appropriate size type in
      ntb_set_mw.  Change the type of the size parameter and two local
      variables used for size.
      
      Even if there is no overflow, a size of zero is invalid here.

      NTB: Fix oops in debugfs when transport is half-up · 260bee94
      Dave Jiang authored
      When the remote side is not up, we do not have all the context for the
      transport, and that causes NULL ptr access. Have the debugfs reads check
      to see if transport is up before we make access.

      NTB: Fix transport stats for multiple devices · c8650fd0
      Dave Jiang authored
      Currently the debugfs does not have files for all NTB transport queue
      pairs.  When there are multiple NTBs present in a system, the QP names
      of the last transport clobber the names of previously added transport
      QPs.  Only the last added QPs can be observed via debugfs.
      
      Create a directory per NTB transport to associate the QPs with that
      transport.  Name the directory the same as the PCI device.

      NTB: Fix ntb_transport out-of-order RX update · da2e5ae5
      Allen Hubbe authored
      It was possible for a synchronous update of the RX index in the error
      case to get ahead of the asynchronous RX index update in the normal
      case.  Change the RX processing to preserve an RX completion order.
      
      There were two error cases.  First, if a buffer is not present to
      receive data, there would be no queue entry to preserve the RX
      completion order.  Instead of dropping the RX frame, leave the RX frame
      in the ring.  Schedule RX processing when RX entries are enqueued, in
      case there are RX frames waiting in the ring to be received.
      
      Second, if a buffer is too small to receive data, drop the frame in the
      ring, mark the RX entry as done, and indicate the error in the RX entry
      length.  Check for a negative length in the receive callback in
      ntb_netdev, and count occurrences as rx_length_errors.

      Pull MIPS fixes from Ralf Baechle:
       "Another round of MIPS fixes for 4.2.  No area does particularly stand
        out but we have a two unpleasant ones:
      
         - Kernel ptes are marked with a global bit which allows the kernel to
           share kernel TLB entries between all processes.  For this to work
           both entries of an adjacent even/odd pte pair need to have the
           global bit set.  There has been a subtle race in setting the other
           entry's global bit since ~ 2000 but it take particularly
           pathological workloads that essentially do mostly vmalloc/vfree to
           trigger this.
      
           This pull request fixes the 64-bit case but leaves the case of 32
           bit CPUs with 64 bit ptes unsolved for now.  The unfixed cases
           affect hardware that is not available in the field yet.
      
         - Instruction emulation requires loading instructions from user space
           but the current fast but simplistic approach will fail on pages
           that are PROT_EXEC but !PROT_READ.  For this reason we temporarily
           do not permit this permission and will map pages with PROT_EXEC |
           PROT_READ.
      
        The remainder of this pull request is more or less across the field
        and the short log explains them well"
