      aio: fix kioctx not being freed after cancellation at exit time · 03e04f04
      Benjamin LaHaise 提交于
      The recent changes overhauling fs/aio.c introduced a bug that results in
      the kioctx not being freed when outstanding kiocbs are cancelled at
      exit_aio() time.  Specifically, a kiocb that is cancelled has its
      completion events discarded by batch_complete_aio(), which then fails to
      wake up the process stuck in free_ioctx().  Fix this by modifying the
      wait_event() condition in free_ioctx() appropriately.
      
      This patch was tested with the cancel operation in the thread based code
      posted yesterday.

      mm/pagewalk.c: walk_page_range should avoid VM_PFNMAP areas · a9ff785e
      Cliff Wickman 提交于
      A panic can be caused by simply cat'ing /proc/<pid>/smaps while an
      application has a VM_PFNMAP range.  It happened in-house when a
      benchmarker was trying to decipher the memory layout of his program.
      
      /proc/<pid>/smaps and similar walks through a user page table should not
      be looking at VM_PFNMAP areas.
      
      Certain tests in walk_page_range() (specifically split_huge_page_pmd())
      assume that all the mapped PFN's are backed with page structures.  And
      this is not usually true for VM_PFNMAP areas.  This can result in panics
      on kernel page faults when attempting to address those page structures.
      
      There are a half dozen callers of walk_page_range() that walk through a
      task's entire page table (as N.  Horiguchi pointed out).  So rather than
      change all of them, this patch changes just walk_page_range() to ignore
      VM_PFNMAP areas.
      
      The logic of hugetlb_vma() is moved back into walk_page_range(), as we
      want to test any vma in the range.
      
      VM_PFNMAP areas are used by:
      - graphics memory manager   gpu/drm/drm_gem.c
      - global reference unit     sgi-gru/grufile.c
      - sgi special memory        char/mspec.c
      - and probably several out-of-tree modules

      ocfs2: goto out_unlock if ocfs2_get_clusters_nocache() failed in ocfs2_fiemap() · b4ca2b4b
      Joseph Qi 提交于
      Last time we found there is lock/unlock bug in ocfs2_file_aio_write, and
      then we did a thorough search for all lock resources in
      ocfs2_inode_info, including rw, inode and open lockres and found this
      bug.  My kernel version is 3.0.13, and it is also in the lastest version
      3.9.  In ocfs2_fiemap, once ocfs2_get_clusters_nocache failed, it should
      goto out_unlock instead of out, because we need release buffer head, up
      read alloc sem and unlock inode.

      random: fix accounting race condition with lockless irq entropy_count update · 10b3a32d
      Jiri Kosina 提交于
      Commit 902c098a ("random: use lockless techniques in the interrupt
      path") turned IRQ path from being spinlock protected into lockless
      cmpxchg-retry update.
      
      That commit removed r->lock serialization between crediting entropy bits
      from IRQ context and accounting when extracting entropy on userspace
      read path, but didn't turn the r->entropy_count reads/updates in
      account() to use cmpxchg as well.
      
      It has been observed, that under certain circumstances this leads to
      read() on /dev/urandom to return 0 (EOF), as r->entropy_count gets
      corrupted and becomes negative, which in turn results in propagating 0
      all the way from account() to the actual read() call.
      
      Convert the accounting code to be the proper lockless counterpart of
      what has been partially done by 902c098a.

      drivers/char/random.c: fix priming of last_data · 1e7e2e05
      Jarod Wilson 提交于
      Commit ec8f02da ("random: prime last_data value per fips
      requirements") added priming of last_data per fips requirements.
      
      Unfortuantely, it did so in a way that can lead to multiple threads all
      incrementing nbytes, but only one actually doing anything with the extra
      data, which leads to some fun random corruption and panics.
      
      The fix is to simply do everything needed to prime last_data in a single
      shot, so there's no window for multiple cpus to increment nbytes -- in
      fact, we won't even increment or decrement nbytes anymore, we'll just
      extract the needed EXTRACT_SIZE one time per pool and then carry on with
      the normal routine.
      
      All these changes have been tested across multiple hosts and
      architectures where panics were previously encoutered.  The code changes
      are are strictly limited to areas only touched when when booted in fips
      mode.
      
      This change should also go into 3.8-stable, to make the myriads of fips
      users on 3.8.x happy.

      Ryusuke Konishi 提交于
      nilfs2: fix issue of nilfs_set_page_dirty for page at EOF boundary
      
      DESCRIPTION:
       There are use-cases when NILFS2 file system (formatted with block size
      lesser than 4 KB) can be remounted in RO mode because of encountering of
      "broken bmap" issue.
      
      The issue was reported by Anthony Doggett <Anthony2486@interfaces.org.uk>:
       "The machine I've been trialling nilfs on is running Debian Testing,
        Linux version 3.2.0-4-686-pae (debian-kernel@lists.debian.org) (gcc
        version 4.6.3 (Debian 4.6.3-14) ) #1 SMP Debian 3.2.35-2), but I've
        also reproduced it (identically) with Debian Unstable amd64 and Debian
        Experimental (using the 3.8-trunk kernel).  The problematic partitions
        were formatted with "mkfs.nilfs2 -b 1024 -B 8192"."
      
      SYMPTOMS:
      (1) System log contains error messages likewise:
      
          [63102.496756] nilfs_direct_assign: invalid pointer: 0
          [63102.496786] NILFS error (device dm-17): nilfs_bmap_assign: broken bmap (inode number=28)
          [63102.496798]
          [63102.524403] Remounting filesystem read-only
      
      (2) The NILFS2 file system is remounted in RO mode.
      
      REPRODUSING PATH:
      (1) Create volume group with name "unencrypted" by means of vgcreate utility.
      (2) Run script (prepared by Anthony Doggett <Anthony2486@interfaces.org.uk>):
      
      ----------------[BEGIN SCRIPT]--------------------
      
      VG=unencrypted

      mkdir /var/tmp/n
      mkdir /var/tmp/n/ntest
      mount /dev/mapper/$VG-ntest /var/tmp/n/ntest
      mkdir /var/tmp/n/ntest/thedir
      cd /var/tmp/n/ntest/thedir

      darcs whatsnew || true
      date
      sleep 2
      dmesg|tail -n 5
      ----------------[END SCRIPT]--------------------
      
      REPRODUCIBILITY: 100%
      
      INVESTIGATION:
      As it was discovered, the issue takes place during segment
      construction after executing such sequence of user-space operations:
      
        open("_darcs/index", O_RDWR|O_CREAT|O_NOCTTY, 0666) = 7
        fstat(7, {st_mode=S_IFREG|0644, st_size=0, ...}) = 0
        ftruncate(7, 60)
      
      The error message "NILFS error (device dm-17): nilfs_bmap_assign: broken
      bmap (inode number=28)" takes place because of trying to get block
      number for third block of the file with logical offset #3072 bytes.  As
      it is possible to see from above output, the file has 60 bytes of the
      whole size.  So, it is enough one block (1 KB in size) allocation for
      the whole file.  Trying to operate with several blocks instead of one
      takes place because of discovering several dirty buffers for this file
      in nilfs_segctor_scan_file() method.
      
      The root cause of this issue is in nilfs_set_page_dirty function which
      is called just before writing to an mmapped page.
      
      When nilfs_page_mkwrite function handles a page at EOF boundary, it
      fills hole blocks only inside EOF through __block_page_mkwrite().
      
      The __block_page_mkwrite() function calls set_page_dirty() after filling
      hole blocks, thus nilfs_set_page_dirty function (=
      a_ops->set_page_dirty) is called.  However, the current implementation
      of nilfs_set_page_dirty() wrongly marks all buffers dirty even for page
      at EOF boundary.
      
      As a result, buffers outside EOF are inconsistently marked dirty and
      queued for write even though they are not mapped with nilfs_get_block
      function.
      
      FIX:
      This modifies nilfs_set_page_dirty() not to mark hole blocks dirty.

      In reviewing man pages, I noticed that io_getevents is documented to
      update the timeout that gets passed into the library call.  This doesn't
      happen in kernel space or in the library (even though it's documented to
      do so in both places).  Unless there is objection, I'd like to fix the
      comments/docs to match the code (I will also update the man page upon

      mm compaction: fix of improper cache flush in migration code · c2cc499c
      Leonid Yegoshin 提交于
      Page 'new' during MIGRATION can't be flushed with flush_cache_page().
      Using flush_cache_page(vma, addr, pfn) is justified only if the page is
      already placed in process page table, and that is done right after
      flush_cache_page().  But without it the arch function has no knowledge
      of process PTE and does nothing.
      
      Besides that, flush_cache_page() flushes an application cache page, but
      the kernel has a different page virtual address and dirtied it.
      
      Replace it with flush_dcache_page(new) which is the proper usage.
      
      The old page is flushed in try_to_unmap_one() before migration.
      
      This bug takes place in Sead3 board with M14Kc MIPS CPU without cache
      aliasing (but Harvard arch - separate I and D cache) in tight memory
      environment (128MB) each 1-3days on SOAK test.  It fails in cc1 during
      kernel build (SIGILL, SIGBUS, SIGSEG) if CONFIG_COMPACTION is switched
      ON.

      rapidio/tsi721: fix bug in MSI interrupt handling · 1ccc819d
      Alexandre Bounine 提交于
      Fix bug in MSI interrupt handling which causes loss of event
      notifications.
      
      Typical indication of lost MSI interrupts are stalled message and
      doorbell transfers between RapidIO endpoints.  To avoid loss of MSI
      interrupts all interrupts from the device must be disabled on entering
      the interrupt handler routine and re-enabled when exiting it.
      Re-enabling device interrupts will trigger new MSI message(s) if Tsi721
      registered new events since entering interrupt handler routine.
      
      This patch is applicable to kernel versions starting from v3.2.

      mm: memcg: remove incorrect VM_BUG_ON for swap cache pages in uncharge · 28ccddf7
      Johannes Weiner 提交于
      Commit 0c59b89c ("mm: memcg: push down PageSwapCache check into
      uncharge entry functions") added a VM_BUG_ON() on PageSwapCache in the
      uncharge path after checking that page flag once, assuming that the
      state is stable in all paths, but this is not the case and the condition
      triggers in user environments.  An uncharge after the last page table
      reference to the page goes away can race with reclaim adding the page to
      swap cache.
      
      Swap cache pages are usually uncharged when they are freed after
      swapout, from a path that also handles swap usage accounting and memcg
      lifetime management.  However, since the last page table reference is
      gone and thus no references to the swap slot left, the swap slot will be
      freed shortly when reclaim attempts to write the page to disk.  The
      whole swap accounting is not even necessary.
      
      So while the race condition for which this VM_BUG_ON was added is real
      and actually existed all along, there are no negative effects.  Remove
      the VM_BUG_ON again.

      drivers/video: implement a simple framebuffer driver · 26549c8d
      Stephen Warren 提交于
      A simple frame-buffer describes a raw memory region that may be rendered
      to, with the assumption that the display hardware has already been set
      up to scan out from that buffer.
      
      This is useful in cases where a bootloader exists and has set up the
      display hardware, but a Linux driver doesn't yet exist for the display
      hardware.
      
      Examples use-cases include:
      
      * The built-in LCD panels on the Samsung ARM chromebook, and Tegra
        devices, and likely many other ARM or embedded systems.  These cannot
        yet be supported using a full graphics driver, since the panel control
        should be provided by the CDF (Common Display Framework), which has been
        stuck in design/review for quite some time.  One could support these
        panels using custom SoC-specific code, but there is a desire to use
        common infra-structure rather than having each SoC vendor invent their
        own code, hence the desire to wait for CDF.
      
      * Hardware for which a full graphics driver is not yet available, and
        the path to obtain one upstream isn't yet clear.  For example, the
        Raspberry Pi.
      
      * Any hardware in early stages of upstreaming, before a full graphics
        driver has been tackled.  This driver can provide a graphical boot
        console (even full X support) much earlier in the upstreaming process,
        thus making new SoC or board support more generally useful earlier.

      ocfs2: unlock rw lock if inode lock failed · afe1bb73

      Xiao Guangrong 提交于
      Commit 751efd86 ("mmu_notifier_unregister NULL Pointer deref and
      multiple ->release()") breaks the fix 3ad3d901 ("mm: mmu_notifier:
      fix freed page still mapped in secondary MMU").
      
      Since hlist_for_each_entry_rcu() is changed now, we can not revert that
      patch directly, so this patch reverts the commit and simply fix the bug
      spotted by that patch
      
      This bug spotted by commit 751efd86 is:
      
          There is a race condition between mmu_notifier_unregister() and
          __mmu_notifier_release().
      
          Assume two tasks, one calling mmu_notifier_unregister() as a result
          of a filp_close() ->flush() callout (task A), and the other calling
          mmu_notifier_release() from an mmput() (task B).
      
                              A                               B

          t2            if (!hlist_unhashed())
          t3                                            srcu_read_unlock()
          t4            srcu_read_lock()
          t5                                            hlist_del_init_rcu()
          t6                                            synchronize_srcu()
          t7            srcu_read_unlock()
          t8            hlist_del_rcu()  <--- NULL pointer deref.
      
      This can be fixed by using hlist_del_init_rcu instead of hlist_del_rcu.
      
      The another issue spotted in the commit is "multiple ->release()
      callouts", we needn't care it too much because it is really rare (e.g,
      can not happen on kvm since mmu-notify is unregistered after
      exit_mmap()) and the later call of multiple ->release should be fast
      since all the pages have already been released by the first call.
      Anyway, this issue should be fixed in a separate patch.
      
      -stable suggestions: Any version that has commit 751efd86 need to be
      backported.  I find the oldest version has this commit is 3.0-stable.

      wait: fix false timeouts when using wait_event_timeout() · 4c663cfc
      Imre Deak 提交于
      Many callers of the wait_event_timeout() and
      wait_event_interruptible_timeout() expect that the return value will be
      positive if the specified condition becomes true before the timeout
      elapses.  However, at the moment this isn't guaranteed.  If the wake-up
      handler is delayed enough, the time remaining until timeout will be
      calculated as 0 - and passed back as a return value - even if the
      condition became true before the timeout has passed.
      
      Fix this by returning at least 1 if the condition becomes true.  This
      semantic is in line with what wait_for_condition_timeout() does; see
      commit bb10ed09 ("sched: fix wait_for_completion_timeout() spurious
      failure under heavy load").
      
      Daniel said "We have 3 instances of this bug in drm/i915.  One case even
      where we switch between the interruptible and not interruptible
      wait_event_timeout variants, foolishly presuming they have the same
      semantics.  I very much like this."

      The following set of patches is intended to simplify process of
      introduction of new RapidIO fabric enumeration/discovery methods.
      
      The first patch offers ability to add new RapidIO enumeration/discovery
      methods using kernel configuration options.  This new configuration
      option mechanism allows to select statically linked or modular
      enumeration/discovery method(s) from the list of existing methods or use
      external module(s).
      
      This patch also updates the currently existing enumeration/discovery
      code to be used as a statically linked or modular method.
      
      The corresponding configuration option is named "Basic
      enumeration/discovery" method.  This is the only one configuration
      option available today but new methods are expected to be introduced
      after adoption of provided patches.
      
      The second patch address a long time complaint of RapidIO subsystem
      users regarding fabric enumeration/discovery start sequence.  Existing
      implementation offers only a boot-time enumeration/discovery start which
      requires synchronized boot of all endpoints in RapidIO network.  While
      it works for small closed configurations with limited number of
      endpoints, using this approach in systems with large number of endpoints
      is quite challenging.
      
      To eliminate requirement for synchronized start the second patch
      introduces RapidIO enumeration/discovery start from user space.
      
      For compatibility with the existing RapidIO subsystem implementation,
      automatic boot time enumeration/discovery start can be configured in by
      specifying "rio-scan.scan=1" command line parameter if statically linked
      basic enumeration method is selected.
      
      This patch:
      
      Rework to implement RapidIO enumeration/discovery method selection
      combined with ability to use enumeration/discovery as a kernel module.
      
      This patch adds ability to introduce new RapidIO enumeration/discovery
      methods using kernel configuration options.  Configuration option
      mechanism allows to select statically linked or modular
      enumeration/discovery method from the list of existing methods or use
      external modules.  If a modular enumeration/discovery is selected each
      RapidIO mport device can have its own method attached to it.
      
      The existing enumeration/discovery code was updated to be used as
      statically linked or modular method.  This configuration option is named
      "Basic enumeration/discovery" method.
      
      Several common routines have been moved from rio-scan.c to make them
      available to other enumeration methods and reduce number of exported
      symbols.

      If the port number is missing from the device-tree the device gets named
      xs` instead of xsa.  This fixes the check for missing ids.
