      fs: fix fd table size alignment properly · d888c83f
      Linus Torvalds authored
      Jason Donenfeld reports that my commit 1c24a186 ("fs: fd tables have
      to be multiples of BITS_PER_LONG") doesn't work, and the reason is an
      embarrassing brown-paper-bag bug.
      
      Yes, we want to align the number of fds to BITS_PER_LONG, and yes, the
      reason they might not be aligned is because the incoming 'max_fd'
      argument might not be aligned.
      
      But aligining the argument - while simple - will cause a "infinitely
      big" maxfd (eg NR_OPEN_MAX) to just overflow to zero.  Which most
      definitely isn't what we want either.
      
      The obvious fix was always just to do the alignment last, but I had
      moved it earlier just to make the patch smaller and the code look
      simpler.  Duh.  It certainly made _me_ look simple.

       "Highlights include:
      
        Features:
      
         - Switch NFS to use readahead instead of the obsolete readpages.
      
         - Readdir fixes to improve cacheability of large directories when
           there are multiple readers and writers.
      
         - Readdir performance improvements when doing a seekdir() immediately
           after opening the directory (common when re-exporting NFS).
      
         - NFS swap improvements from Neil Brown.
      
         - Loosen up memory allocation to permit direct reclaim and write back
           in cases where there is no danger of deadlocking the writeback code
           or NFS swap.
      
         - Avoid sillyrename when the NFSv4 server claims to support the
           necessary features to recover the unlinked but open file after
           reboot.
      
        Bugfixes:
      
         - Patch from Olga to add a mount option to control NFSv4.1 session
           trunking discovery, and default it to being off.
      
         - Fix a lockup in nfs_do_recoalesce().
      
         - Two fixes for list iterator variables being used when pointing to

         - Fix a kernel memory scribble when reading from a non-socket
           transport in /sys/kernel/sunrpc.
      
         - Fix a race where reconnecting to a server could leave the TCP
           socket stuck forever in the connecting state.
      
         - Patch from Neil to fix a shutdown race which can leave the SUNRPC
           transport timer primed after we free the struct xprt itself.
      
         - Patch from Xin Xiong to fix reference count leaks in the NFSv4.2
           copy offload.

      fs: fd tables have to be multiples of BITS_PER_LONG · 1c24a186
      Linus Torvalds authored
      This has always been the rule: fdtables have several bitmaps in them,
      and as a result they have to be sized properly for bitmaps.  We walk
      those bitmaps in chunks of 'unsigned long' in serveral cases, but even
      when we don't, we use the regular kernel bitops that are defined to work
      on arrays of 'unsigned long', not on some byte array.
      
      Now, the distinction between arrays of bytes and 'unsigned long'
      normally only really ends up being noticeable on big-endian systems, but
      Fedor Pchelkin and Alexey Khoroshilov reported that copy_fd_bitmaps()
      could be called with an argument that wasn't even a multiple of
      BITS_PER_BYTE.  And then it fails to do the proper copy even on
      little-endian machines.
      
      The bug wasn't in copy_fd_bitmap(), but in sane_fdtable_size(), which
      didn't actually sanitize the fdtable size sufficiently, and never made
      sure it had the proper BITS_PER_LONG alignment.
      
      That's partly because the alignment historically came not from having to
      explicitly align things, but simply from previous fdtable sizes, and
      from count_open_files(), which counts the file descriptors by walking
      them one 'unsigned long' word at a time and thus naturally ends up doing
      sizing in the proper 'chunks of unsigned long'.
      
      But with the introduction of close_range(), we now have an external
      source of "this is how many files we want to have", and so
      sane_fdtable_size() needs to do a better job.
      
      This also adds that explicit alignment to alloc_fdtable(), although
      there it is mainly just for documentation at a source code level.  The
      arithmetic we do there to pick a reasonable fdtable size already aligns
      the result sufficiently.
      
      In fact,clang notices that the added ALIGN() in that function doesn't
      actually do anything, and does not generate any extra code for it.
      
      It turns out that gcc ends up confusing itself by combining a previous
      constant-sized shift operation with the variable-sized shift operations
      in roundup_pow_of_two().  And probably due to that doesn't notice that
      the ALIGN() is a no-op.  But that's a (tiny) gcc misfeature that doesn't
      matter.  Having the explicit alignment makes sense, and would actually
      matter on a 128-bit architecture if we ever go there.
      
      This also adds big comments above both functions about how fdtable sizes
      have to have that BITS_PER_LONG alignment.

      Absolute paths in $ref should always begin with '/schemas'. The tools
      mostly work with it omitted, but for correctness the path should be
      everything except the hostname as that is taken from the schema's $id
      value. This scheme is defined in the json-schema spec.

      Rob Herring authored
      'dma-ranges' in the example is written for cell sizes of 2 cells, but
      the schema and example specify sizes of 1 cell. As the h/w has a bus
      address of >32-bits, cell sizes of 2 is correct. Update the schema's
      '#address-cells' and '#size-cells' to be 2 and adjust the example
      throughout.
      
      There's no error currently because dtc only checks 'dma-ranges' is a
      correct multiple number of cells (3) and the schema checking is based on
      bracketing of entries.

      dt-bindings: display: mediatek: Fix examples on new bindings · bff4e302
      AngeloGioacchino Del Regno authored
      To avoid failure of dt_binding_check perform a slight refactoring
      of the examples: the main block is kept, but that required fixing
      the address and size cells, plus the inclusion of missing dt-bindings
      headers, required to parse some of the values assigned to various
      properties.
      
      Fixes: 4ed545e7 ("dt-bindings: display: mediatek: disp: split each block to individual yaml")

      Pull ptrace cleanups from Eric Biederman:
       "This set of changes removes tracehook.h, moves modification of all of
        the ptrace fields inside of siglock to remove races, adds a missing
        permission check to ptrace.c
      
        The removal of tracehook.h is quite significant as it has been a major
        source of confusion in recent years. Much of that confusion was around
        task_work and TIF_NOTIFY_SIGNAL (which I have now decoupled making the
        semantics clearer).
      
        For people who don't know tracehook.h is a vestiage of an attempt to
        implement uprobes like functionality that was never fully merged, and
        was later superseeded by uprobes when uprobes was merged. For many
        years now we have been removing what tracehook functionaly a little
        bit at a time. To the point where anything left in tracehook.h was
        some weird strange thing that was difficult to understand"
