      ftrace: Be first to run code modification on modules · c1bf08ac
      Steven Rostedt authored
      If some other kernel subsystem has a module notifier, and adds a kprobe
      to a ftrace mcount point (now that kprobes work on ftrace points),
      when the ftrace notifier runs it will fail and disable ftrace, as well
      as kprobes that are attached to ftrace points.
      
      Here's the error:

        actual: cc:bb:d2:4b:e1
      
      A kprobe was added to the init_once() function in the fat module on load.
      But this happened before ftrace could have touched the code. As ftrace
      didn't run yet, the kprobe system had no idea it was a ftrace point and
      simply added a breakpoint to the code (0xcc in the cc:bb:d2:4b:e1).
      
      Then when ftrace went to modify the location from a call to mcount/fentry
      into a nop, it didn't see a call op, but instead it saw the breakpoint op
      and not knowing what to do with it, ftrace shut itself down.
      
      The solution is to simply give the ftrace module notifier the max priority.
      This should have been done regardless, as the core code ftrace modification
      also happens very early on in boot up. This makes the module modification
      closer to core modification.

      This happens because sockets do not define the removexattr operation.
      Before removing the xattr, verify the removexattr function pointer is
      not NULL.

      module: fix missing module_mutex unlock · ee61abb3
      Linus Torvalds authored
      Commit 1fb9341a
      
       ("module: put modules in list much earlier") moved
      some of the module initialization code around, and in the process
      changed the exit paths too.  But for the duplicate export symbol error
      case the change made the ddebug_cleanup path jump to after the module
      mutex unlock, even though it happens with the mutex held.
      
      Rusty has some patches to split this function up into some helper
      functions, hopefully the mess of complex goto targets will go away
      eventually.

      ttm: on move memory failure don't leave a node dangling · 014b3440
      Dave Airlie authored
      
      
      if we have a move notify callback, when moving fails, we call move notify
      the opposite way around, however this ends up with *mem containing the mm_node
      from the bo, which means we double free it. This is a follow on to the previous
      fix.

      ttm: don't destroy old mm_node on memcpy failure · 63054186
      Dave Airlie authored
      
      
      When we are using memcpy to move objects around, and we fail to memcpy
      due to lack of memory to populate or failure to finish the copy, we don't
      want to destroy the mm_node that has been copied into old_copy.
      
      While working on a new kms driver that uses memcpy, if I overallocated bo's
      up to the memory limits, and eviction failed, then machine would oops soon
      after due to having an active bo with an already freed drm_mm embedded in it,
      freeing it a second time didn't end well.

      asm-generic, mm: pgtable: convert my_zero_pfn() to macros to fix build · 2f91ec8c
      Kirill A. Shutemov authored
      Commit 816422ad
      
       ("asm-generic, mm: pgtable: consolidate zero page
      helpers") broke the compile on MIPS if SPARSEMEM is enabled.  We get
      this:
      
        In file included from arch/mips/include/asm/pgtable.h:552,
                         from include/linux/mm.h:44,
                         from arch/mips/kernel/asm-offsets.c:14:
        include/asm-generic/pgtable.h: In function 'my_zero_pfn':
        include/asm-generic/pgtable.h:466: error: implicit declaration of function 'page_to_section'
        In file included from arch/mips/kernel/asm-offsets.c:14:
        include/linux/mm.h: At top level:

        include/asm-generic/pgtable.h:466: note: previous implicit declaration of 'page_to_section' was here
      
      Due header files inter-dependencies, the only way I see to fix it is
      convert my_zero_pfn() for __HAVE_COLOR_ZERO_PAGE to macros.

      USB: io_ti: Fix NULL dereference in chase_port() · 1ee0a224
      Wolfgang Frisch authored
      
      
      The tty is NULL when the port is hanging up.
      chase_port() needs to check for this.
      
      This patch is intended for stable series.
      The behavior was observed and tested in Linux 3.2 and 3.7.1.
      
      Johan Hovold submitted a more elaborate patch for the mainline kernel.
