       "Here are a bunch of USB fixes for the 3.7-rc tree.
      
        There's a lot of small USB serial driver fixes, and one larger one
        (the mos7840 driver changes are mostly just moving code around to fix
        problems.) Thanks to Johan Hovold for finding the problems and fixing
        them all up.
      
        Other than those, there is the usual new device ids, xhci bugfixes,
        and gadget driver fixes, nothing out of the ordinary.

      VFS: don't do protected {sym,hard}links by default · 561ec64a
      Linus Torvalds authored
      In commit 800179c9 ("This adds symlink and hardlink restrictions to
      the Linux VFS"), the new link protections were enabled by default, in
      the hope that no actual application would care, despite it being
      technically against legacy UNIX (and documented POSIX) behavior.
      
      However, it does turn out to break some applications.  It's rare, and
      it's unfortunate, but it's unacceptable to break existing systems, so
      we'll have to default to legacy behavior.
      
      In particular, it has broken the way AFD distributes files, see
      
        http://www.dwd.de/AFD/
      
      along with some legacy scripts.
      
      Distributions can end up setting this at initrd time or in system
      scripts: if you have security problems due to link attacks during your
      early boot sequence, you have bigger problems than some kernel sysctl
      setting. Do:
      
      	echo 1 > /proc/sys/fs/protected_symlinks
      	echo 1 > /proc/sys/fs/protected_hardlinks
      
      to re-enable the link protections.
      
      Alternatively, we may at some point introduce a kernel config option
      that sets these kinds of "more secure but not traditional" behavioural
      options automatically.

      Input: wacom - handle split-sensor devices with internal hubs · aea2bf6a
      Jason Gerecke authored
      Like our other pen-and-touch products, the Cintiq 24HD touch needs data
      to be shared between its two sensors to facilitate proximity-based palm
      rejection.
      
      Unlike other tablets that report sensor data through separate interfaces
      of the same USB device, the Cintiq 24HD touch has separate USB devices
      that are connected to an internal USB hub.
      
      This patch makes it possible to designate the USB VID/PID of the other
      device so that the two may share data.  To ensure we don't accidentally
      link to a sensor from a physically separate device (if several have been
      plugged in), we limit the search to siblings (i.e., devices directly
      connected to the same hub).

      Makefile: Documentation for external tool should be correct · 2008713c
      H. Peter Anvin authored
      If one includes documentation for an external tool, it should be
      correct.  This is not:
      
      1. Overriding the input to rngd should typically be neither
         necessary nor desired.  This is especially so since newer
         versions of rngd support a number of different *types* of sources.
      2. The default kernel-exported device is called /dev/hwrng not
         /dev/hwrandom nor /dev/hw_random (both of which were used in the
         past; however, kernel and udev seem to have converged on
         /dev/hwrng.)
      
      Overall it is better if the documentation for rngd is kept with rngd
      rather than in a kernel Makefile.

      pidns: limit the nesting depth of pid namespaces · f2302505
      Andrew Vagin authored
      'struct pid' is a "variable sized struct" - a header with an array of
      upids at the end.
      
      The size of the array depends on a level (depth) of pid namespaces.  Now a
      level of pidns is not limited, so 'struct pid' can be more than one page.
      
      Looks reasonable, that it should be less than a page.  MAX_PIS_NS_LEVEL is
      not calculated from PAGE_SIZE, because in this case it depends on
      architectures, config options and it will be reduced, if someone adds a
      new fields in struct pid or struct upid.
      
      I suggest to set MAX_PIS_NS_LEVEL = 32, because it saves ability to expand
      "struct pid" and it's more than enough for all known for me use-cases.
      When someone finds a reasonable use case, we can add a config option or a
      sysctl parameter.
      
      In addition it will reduce the effect of another problem, when we have
      many nested namespaces and the oldest one starts dying.
      zap_pid_ns_processe will be called for each namespace and find_vpid will
      be called for each process in a namespace.  find_vpid will be called
      minimum max_level^2 / 2 times.  The reason of that is that when we found a
      bit in pidmap, we can't determine this pidns is top for this process or it
      isn't.
      
      vpid is a heavy operation, so a fork bomb, which create many nested
      namespace, can make a system inaccessible for a long time.  For example my
      system becomes inaccessible for a few minutes with 4000 processes.

      drivers/dma/dw_dmac: make driver's endianness configurable · d5ea7b5e
      Hein Tibosch authored
      The dw_dmac driver was originally developed for avr32 to be used with the
      Synopsys DesignWare AHB DMA controller.  Starting from 2.6.38, access to
      the device's i/o memory was done with the little-endian readl/writel
      functions(1)
      
      This broke the driver for the avr32 platform, because it needs big
      (native) endian accessors.  This patch makes the endianness configurable
      using 'DW_DMAC_BIG_ENDIAN_IO', which will default be true for AVR32
      
      I submitted this patch before(2) but then waited for Andy to finish other
      changes to the same module(3).

      mm/mmu_notifier: allocate mmu_notifier in advance · 35cfa2b0
      Gavin Shan authored
      While allocating mmu_notifier with parameter GFP_KERNEL, swap would start
      to work in case of tight available memory.  Eventually, that would lead to
      a deadlock while the swap deamon swaps anonymous pages.  It was caused by

      rbtree: include linux/compiler.h for definition of __always_inline · 29fc7c5a
      Will Deacon authored
      rb_erase_augmented() is a static function annotated with
      __always_inline.  This causes a compile failure when attempting to use
      the rbtree implementation as a library (e.g.  kvm tool):
      
        rbtree_augmented.h:125:24: error: expected `=', `,', `;', `asm' or `__attribute__' before `void'
      
      Include linux/compiler.h in rbtree_augmented.h so that the __always_inline
      macro is resolved correctly.

      genalloc: stop crashing the system when destroying a pool · eedce141
      Thadeu Lima de Souza Cascardo authored
      The genalloc code uses the bitmap API from include/linux/bitmap.h and
      lib/bitmap.c, which is based on long values.  Both bitmap_set from
      lib/bitmap.c and bitmap_set_ll, which is the lockless version from
      genalloc.c, use BITMAP_LAST_WORD_MASK to set the first bits in a long in
      the bitmap.
      
      That one uses (1 << bits) - 1, 0b111, if you are setting the first three
      bits.  This means that the API counts from the least significant bits
      (LSB from now on) to the MSB.  The LSB in the first long is bit 0, then.
      The same works for the lookup functions.
      
      The genalloc code uses longs for the bitmap, as it should.  In
      include/linux/genalloc.h, struct gen_pool_chunk has unsigned long
      bits[0] as its last member.  When allocating the struct, genalloc should
      reserve enough space for the bitmap.  This should be a proper number of
      longs that can fit the amount of bits in the bitmap.
      
      However, genalloc allocates an integer number of bytes that fit the
      amount of bits, but may not be an integer amount of longs.  9 bytes, for
      example, could be allocated for 70 bits.
      
      This is a problem in itself if the Least Significat Bit in a long is in
      the byte with the largest address, which happens in Big Endian machines.
      This means genalloc is not allocating the byte in which it will try to
      set or check for a bit.
      
      This may end up in memory corruption, where genalloc will try to set the
      bits it has not allocated.  In fact, genalloc may not set these bits
      because it may find them already set, because they were not zeroed since
      they were not allocated.  And that's what causes a BUG when
      gen_pool_destroy is called and check for any set bits.
      
      What really happens is that genalloc uses kmalloc_node with __GFP_ZERO
      on gen_pool_add_virt.  With SLAB and SLUB, this means the whole slab
      will be cleared, not only the requested bytes.  Since struct
      gen_pool_chunk has a size that is a multiple of 8, and slab sizes are
      multiples of 8, we get lucky and allocate and clear the right amount of
      bytes.
      
      Hower, this is not the case with SLOB or with older code that did memset
      after allocating instead of using __GFP_ZERO.
      
      So, a simple module as this (running 3.6.0), will cause a crash when
      rmmod'ed.
