      rmap: recompute pgoff for unmapping huge page · 369a713e
      Hillf Danton authored
      We have to recompute pgoff if the given page is huge, since result based
      on HPAGE_SIZE is not approapriate for scanning the vma interval tree, as
      shown by commit 36e4f20a ("hugetlb: do not use vma_hugecache_offset()
      for vma_prio_tree_foreach").

      vm: adjust ifdef for TINY_RCU · 8375ad98
      Paul E. McKenney authored
      There is an ifdef in page_cache_get_speculative() that checks for !SMP
      and TREE_RCU, which has been an impossible combination since the advent
      of TINY_RCU.  The ifdef enables a fastpath that is valid when preemption
      is disabled by rcu_read_lock() in UP systems, which is the case when
      TINY_RCU is enabled.  This commit therefore adjusts the ifdef to
      generate the fastpath when TINY_RCU is enabled.

      mm, show_mem: suppress page counts in non-blockable contexts · 4b59e6c4
      David Rientjes authored
      On large systems with a lot of memory, walking all RAM to determine page
      types may take a half second or even more.
      
      In non-blockable contexts, the page allocator will emit a page allocation
      failure warning unless __GFP_NOWARN is specified.  In such contexts, irqs
      are typically disabled and such a lengthy delay may even result in NMI
      watchdog timeouts.
      
      To fix this, suppress the page walk in such contexts when printing the
      page allocation failure warning.

      mm: trace filemap add and del · fe0bfaaf
      Robert Jarzmik authored
      Use the events API to trace filemap loading and unloading of file pieces
      into the page cache.
      
      This patch aims at tracing the eviction reload cycle of executable and
      shared libraries pages in a memory constrained environment.
      
      The typical usage is to spot a specific device and inode (for example
      /lib/libc.so) to see the eviction cycles, and find out if frequently
      used code is rather spread across many pages (bad) or coallesced (good).

      HWPOISON: check dirty flag to match against clean page · e3986295
      Naoya Horiguchi authored
      Currently page_action() does not check dirty flag to determine whether
      the error page is "clean mlocked/unevictable LRU" page.  This doesn't
      cause any misjudgement because we do matching against "dirty
      mlocked/unevictable LRU" just before the check.  But in order to make
      code consistent and/or to avoid potential regression, we had better
      check dirty flag explicitly.

      debug_locks.h: make warning more verbose · 2c2fea11
      James Hogan authored
      The WARN_ON(1) in DEBUG_LOCKS_WARN_ON is surprisingly awkward to track
      down when it's hit, as it's usually buried in macros, causing multiple
      instances to land on the same line number.
      
      This patch makes it more useful by switching to:
      
          WARN(1, "DEBUG_LOCKS_WARN_ON(%s)", #c);
      
      so that the particular DEBUG_LOCKS_WARN_ON is more easily identified and
      grep'd for.  For example:
      
          WARNING: at kernel/mutex.c:198 _mutex_lock_nested+0x31c/0x380()
          DEBUG_LOCKS_WARN_ON(l->magic != l)

      scripts/decodecode: make faulting insn ptr more robust · 18ff44b1
      Borislav Petkov authored
      It can accidentally happen that the faulting insn (the exact instruction
      bytes) is repeated a little further on in the trace.  This causes that
      same instruction to be tagged twice, see example below.
      
      What we want to do, however, is to track back from the end of the whole
      disassembly so many lines as the slice which starts with the faulting
      instruction is long.  This leads us to the actual faulting instruction
      and *then* we tag it.
      
      While we're at it, we can drop the sed "g" flag because we address only
      this one line.
      
      Also, if we point to an instruction which changes decoding depending on
      the slice being objdumped, like a Jcc insn, for example, we do not even
      tag it as a faulting instruction because the instruction decode changes
      in the second slice but we use that second format as a regex on the
      fsrst disassembled buffer and more often than not that instruction
      doesn't match.
      
      Again, simply tag the line which is deduced from the original "<>"
      marking we've received from the kernel.
      
      This also solves the pathologic issue of multiple tagging like this:
      
        29:*  0f 0b                   ud2         <-- trapping instruction
        2b:*  0f 0b                   ud2         <-- trapping instruction
        2d:*  0f 0b                   ud2         <-- trapping instruction
      
      Double tagging example:
      
      Code: 34 dd 40 30 ad 81 48 c7 c0 80 f6 00 00 48 8b 3c 30 48 01 c6 b8 ff ff ff ff 48 8d 57 f0 48 39 f7 74 2f 49 8b 4c 24 08 48 8b 47 f0 <48> 39 48 08 75 0e eb 2a 66 90 48 8b 40 f0 48 39 48 08 74 1e 48

      There is a kernel memory leak observed when the proc file

      The reason is that in fscache_stats_open, single_open is called and the
      respective release function is not called during release.  Hence fix
      with correct release function - single_release().

      Convert the struct i2c_msg initialization to C99 format.  This makes
      maintaining and editing the code simpler.  Also helps once other fields
      like transferred are added in future.

      kernel/auditfilter.c: tree and watch will memory leak when failure occurs · 373e0f34
      Chen Gang authored
      In audit_data_to_entry() when a failure occurs we must check and free
      the tree and watch to avoid a memory leak.
      
        test:
          plan:
            test command:
              "auditctl -a exit,always -w /etc -F auid=-1"
              (on fedora17, need modify auditctl to let "-w /etc" has effect)
            running:
              under fedora17 x86_64, 2 CPUs 3.20GHz, 2.5GB RAM.
              let 15 auditctl processes continue running at the same time.
            monitor command:
              watch -d -n 1 "cat /proc/meminfo | awk '{print \$2}' \
                | head -n 4 | xargs \
                | awk '{print \"used \",\$1 - \$2 - \$3 - \$4}'"
      
          result:
            for original version:
              will use up all memory, within 3 hours.
              kill all auditctl, the memory still does not free.
            for new version (apply this patch):
              after 14 hours later, not find issues.

      We only need to check if kauditd is valid after we start it, if kauditd

      kthread: kill task_get_live_kthread() · b5c5442b
      Oleg Nesterov authored
      task_get_live_kthread() looks confusing and unneeded.  It does
      get_task_struct() but only kthread_stop() needs this, it can be called
      even if the calller doesn't have a reference when we know that this
      kthread can't exit until we do kthread_stop().
      
      kthread_park() and kthread_unpark() do not need get_task_struct(), the
      callers already have the reference.  And it can not help if we can race
      with the exiting kthread anyway, kthread_park() can hang forever in this
      case.
      
      Change kthread_park() and kthread_unpark() to use to_live_kthread(),
      change kthread_stop() to do get_task_struct() by hand and remove
      task_get_live_kthread().

      kthread: introduce to_live_kthread() · 4ecdafc8
      Oleg Nesterov authored
      "k->vfork_done != NULL" with a barrier() after to_kthread(k) in
      task_get_live_kthread(k) looks unclear, and sub-optimal because we load
      ->vfork_done twice.
      
      All we need is to ensure that we do not return to_kthread(NULL).  Add a
      new trivial helper which loads/checks ->vfork_done once, this also looks
      more understandable.

      Pull pinctrl update from Linus Walleij:
       "These are the pinctrl changes for v3.10:
      
         - Patrice Chotard contributed a new configuration debugfs interface
           and reintroduced fine-grained locking into the core: instead of
           having a "big pinctrl lock" we have a per-controller lock and
           specialized locks for the global controller and pinctrl handle
           lists.
      
         - Haoijan Zhuang deleted all the PXA and MMP2 pinctrl drivers and
           replaced them with pinctrl-single (which is also used by other
           SoCs) so we are gaining consolidation.  The platform particulars
           now come in through the device tree.
      
         - Haoijan also added support for generic pin config into the
           pinctrl-single driver which is another big consolidation win.
      
         - Finally also GPIO ranges are now supported by the pinctrl-single
           driver.
      
         - Tomasz Figa contributed a new Samsung S3C pinctrl driver, bringing
           more of the older Samsung platforms under the pinctrl umbrella and
           out of arch/arm.
      
         - Maxime Ripard contributed new Allwinner A10/A13 drivers.
      
         - Sachin Kamat, Wei Yongjun and Axel Lin did a lot of cleanups."
