      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
      
      percpu.h is included by sched.h and module.h and thus ends up being
      included when building most .c files.  percpu.h includes slab.h which
      in turn includes gfp.h making everything defined by the two files
      universally available and complicating inclusion dependencies.
      
      percpu.h -> slab.h dependency is about to be removed.  Prepare for
      this change by updating users of gfp and slab facilities include those
      headers directly instead of assuming availability.  As this conversion
      needs to touch large number of source files, the following script is
      used as the basis of conversion.
      
        http://userweb.kernel.org/~tj/misc/slabh-sweep.py
      
      The script does the followings.
      
      * Scan files for gfp and slab usages and update includes such that
        only the necessary includes are there.  ie. if only gfp is used,
        gfp.h, if slab is used, slab.h.
      
      * When the script inserts a new include, it looks at the include
        blocks and try to put the new include such that its order conforms
        to its surrounding.  It's put in the include block which contains
        core kernel includes, in the same order that the rest are ordered -
        alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
        doesn't seem to be any matching order.
      
      * If the script can't find a place to put a new include (mostly
        because the file doesn't have fitting include block), it prints out
        an error message indicating which .h file needs to be added to the
        file.
      
      The conversion was done in the following steps.
      
      1. The initial automatic conversion of all .c files updated slightly
         over 4000 files, deleting around 700 includes and adding ~480 gfp.h
         and ~3000 slab.h inclusions.  The script emitted errors for ~400
         files.
      
      2. Each error was manually checked.  Some didn't need the inclusion,
         some needed manual addition while adding it to implementation .h or
         embedding .c file was more appropriate for others.  This step added
         inclusions to around 150 files.
      
      3. The script was run again and the output was compared to the edits
         from #2 to make sure no file was left behind.
      
      4. Several build tests were done and a couple of problems were fixed.
         e.g. lib/decompress_*.c used malloc/free() wrappers around slab
         APIs requiring slab.h to be added manually.
      
      5. The script was run on all .h files but without automatically
         editing them as sprinkling gfp.h and slab.h inclusions around .h
         files could easily lead to inclusion dependency hell.  Most gfp.h
         inclusion directives were ignored as stuff from gfp.h was usually
         wildly available and often used in preprocessor macros.  Each
         slab.h inclusion directive was examined and added manually as
         necessary.
      
      6. percpu.h was updated not to include slab.h.
      
      7. Build test were done on the following configurations and failures
         were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
         distributed build env didn't work with gcov compiles) and a few
         more options had to be turned off depending on archs to make things
         build (like ipr on powerpc/64 which failed due to missing writeq).
      
         * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
         * powerpc and powerpc64 SMP allmodconfig
         * sparc and sparc64 SMP allmodconfig
         * ia64 SMP allmodconfig
         * s390 SMP allmodconfig
         * alpha SMP allmodconfig
         * um on x86_64 SMP allmodconfig
      
      8. percpu.h modifications were reverted so that it could be applied as
         a separate patch and serve as bisection point.
      
      Given the fact that I had only a couple of failures from tests on step
      6, I'm fairly confident about the coverage of this conversion patch.
      If there is a breakage, it's likely to be something in one of the arch
      headers which should be easily discoverable easily on most builds of
      the specific arch.

      x86: don't include slab.h from arch/x86/include/asm/pgtable_32.h · 57f4c226
      Tejun Heo 提交于
      Including slab.h from x86 pgtable_32.h creates a troublesome
      dependency chain w/ ftrace enabled.  The following chain leads to
      inclusion of pgtable_32.h from define_trace.h.
      
       trace/define_trace.h
       trace/ftrace.h
       linux/ftrace_event.h
       linux/ring_buffer.h
       linux/mm.h
       asm/pgtable.h
       asm/pgtable_32.h
      
      slab.h itself defines trace hooks via
      
       linux/sl[aou]b_def.h
       linux/kmemtrace.h
       trace/events/kmem.h
      
      If slab.h is not included before define_trace.h is included, this
      leads to duplicate definitions of kmemtrace hooks or other include
      dependency problems.
      
      pgtable_32.h doesn't need slab.h to begin with.  Don't include it from
      there.

      ext3: fix broken handling of EXT3_STATE_NEW · de329820
      Linus Torvalds 提交于
      In commit 9df93939 ("ext3: Use bitops to read/modify
      EXT3_I(inode)->i_state") ext3 changed its internal 'i_state' variable to
      use bitops for its state handling.  However, unline the same ext4
      change, it didn't actually change the name of the field when it changed
      the semantics of it.
      
      As a result, an old use of 'i_state' remained in fs/ext3/ialloc.c that
      initialized the field to EXT3_STATE_NEW.  And that does not work
      _at_all_ when we're now working with individually named bits rather than
      values that get masked.  So the code tried to mark the state to be new,
      but in actual fact set the field to EXT3_STATE_JDATA.  Which makes no
      sense at all, and screws up all the code that checks whether the inode
      was newly allocated.
      
      In particular, it made the xattr code unhappy, and caused various random
      behavior, like apparently
      
      	https://bugzilla.redhat.com/show_bug.cgi?id=577911
      
      So fix the initialization, and rename the field to match ext4 so that we
      don't have this happen again.

      r8169: offical fix for CVE-2009-4537 (overlength frame DMAs) · c0cd884a
      Neil Horman 提交于
      Official patch to fix the r8169 frame length check error.
      
      Based on this initial thread:
      http://marc.info/?l=linux-netdev&m=126202972828626&w=1
      This is the official patch to fix the frame length problems in the r8169
      driver.  As noted in the previous thread, while this patch incurs a performance
      hit on the driver, its possible to improve performance dynamically by updating
      the mtu and rx_copybreak values at runtime to return performance to what it was
      for those NICS which are unaffected by the ideosyncracy (if there are any).
      
      Summary:
      
          A while back Eric submitted a patch for r8169 in which the proper
      allocated frame size was written to RXMaxSize to prevent the NIC from dmaing too
      much data.  This was done in commit fdd7b4c3.  A
      long time prior to that however, Francois posted
      126fa4b9, which expiclitly disabled the MaxSize
      setting due to the fact that the hardware behaved in odd ways when overlong
      frames were received on NIC's supported by this driver.  This was mentioned in a
      security conference recently:
      http://events.ccc.de/congress/2009/Fahrplan//events/3596.en.html
      
      It seems that if we can't enable frame size filtering, then, as Eric correctly
      noticed, we can find ourselves DMA-ing too much data to a buffer, causing
      corruption.  As a result is seems that we are forced to allocate a frame which
      is ready to handle a maximally sized receive.
      
      This obviously has performance issues with it, so to mitigate that issue, this
      patch does two things:
      
      1) Raises the copybreak value to the frame allocation size, which should force
      appropriately sized packets to get allocated on rx, rather than a full new 16k
      buffer.
      
      2) This patch only disables frame filtering initially (i.e., during the NIC
      open), changing the MTU results in ring buffer allocation of a size in relation
      to the new mtu (along with a warning indicating that this is dangerous).
      
      Because of item (2), individuals who can't cope with the performance hit (or can
      otherwise filter frames to prevent the bug), or who have hardware they are sure
      is unaffected by this issue, can manually lower the copybreak and reset the mtu
      such that performance is restored easily.

      But unlike when the userspace actually does load and store
      instructions, the top 32-bits don't get automatically truncated by the
      cpu in kernel mode (because the kernel doesn't execute with PSTATE_AM
      address masking enabled).
      
      So we have to do it by hand.
