      perf_counter: Fix buffer overflow in perf_copy_attr() · b3e62e35
      Xiao Guangrong authored
      If we pass a big size data over perf_counter_open() syscall,
      the kernel will copy this data to a small buffer, it will
      cause kernel crash.
      
      This bug makes the kernel unsafe and non-root local user can
      trigger it.

      SELinux: inline selinux_is_enabled in !CONFIG_SECURITY_SELINUX · 8a478905
      Eric Paris authored
      Without this patch building a kernel emits millions of warning like:
      
      include/linux/selinux.h:92: warning: ?selinux_is_enabled? defined but not used
      
      When it is build without CONFIG_SECURITY_SELINUX.  This is harmless, but
      the function should be inlined, so it gets compiled out.

      fix undefined reference to user_shm_unlock · 2195d281
      Hugh Dickins authored
      My 353d5c30 "mm: fix hugetlb bug due to
      user_shm_unlock call" broke the CONFIG_SYSVIPC !CONFIG_MMU build of both
      2.6.31 and 2.6.30.6: "undefined reference to `user_shm_unlock'".
      
      gcc didn't understand my comment! so couldn't figure out to optimize
      away user_shm_unlock() from the error path in the hugetlb-less case, as
      it does elsewhere.  Help it to do so, in a language it understands.

      KEYS: Fix garbage collector · c08ef808
      David Howells authored
      Fix a number of problems with the new key garbage collector:
      
       (1) A rogue semicolon in keyring_gc() was causing the initial count of dead
           keys to be miscalculated.
      
       (2) A missing return in keyring_gc() meant that under certain circumstances,
           the keyring semaphore would be unlocked twice.
      
       (3) The key serial tree iterator (key_garbage_collector()) part of the garbage
           collector has been modified to:
      
           (a) Complete each scan of the keyrings before setting the new timer.
      
           (b) Only set the new timer for keys that have yet to expire.  This means
               that the new timer is now calculated correctly, and the gc doesn't
               get into a loop continually scanning for keys that have expired, and
               preventing other things from happening, like RCU cleaning up the old
               keyring contents.
      
           (c) Perform an extra scan if any keys were garbage collected in this one
           	 as a key might become garbage during a scan, and (b) could mean we
           	 don't set the timer again.
      
       (4) Made key_schedule_gc() take the time at which to do a collection run,
           rather than the time at which the key expires.  This means the collection
           of dead keys (key type unregistered) can happen immediately.

      When we exit early from keyctl_session_to_parent because of permissions or

      Xiaotian Feng authored
      transition_started should be set once the preparation of devices for
      a PM has started, reset before starting to resume devices. When
      resuming devices, kernel calls dpm_resume_noirq then
      dpm_resume_end(dpm_resume).  Thus we should reset transition_started
      at dpm_resume_noirq.

      PM / Hibernate / Memory hotplug: Always use for_each_populated_zone() · 98e73dc5
      Gerald Schaefer authored
      Use for_each_populated_zone() instead of for_each_zone() in hibernation
      code. This fixes a bug on s390, where we allow both config options
      HIBERNATION and MEMORY_HOTPLUG, so that we also have a ZONE_MOVABLE
      here. We only allow hibernation if no memory hotplug operation was
      performed, so in fact both features can only be used exclusively, but
      this way we don't need 2 differently configured (distribution) kernels.
      
      If we have an unpopulated ZONE_MOVABLE, we allow hibernation but run
      into a BUG_ON() in memory_bm_test/set/clear_bit() because hibernation
      code iterates through all zones, not only the populated zones, in
      several places. For example, swsusp_free() does for_each_zone() and
      then checks for pfn_valid(), which is true even if the zone is not
      populated, resulting in a BUG_ON() later because the pfn cannot be
      found in the memory bitmap.
      
      Replacing all occurences of for_each_zone() in hibernation code with
      for_each_populated_zone() would fix this issue.

      PM/Hibernate: Do not try to allocate too much memory too hard (rev. 2) · ef4aede3
      Rafael J. Wysocki authored
      We want to avoid attempting to free too much memory too hard during
      hibernation, so estimate the minimum size of the image to use as the
      lower limit for preallocating memory.
      
      The approach here is based on the (experimental) observation that we
      can't free more page frames than the sum of:
      
      * global_page_state(NR_SLAB_RECLAIMABLE)
      * global_page_state(NR_ACTIVE_ANON)
      * global_page_state(NR_INACTIVE_ANON)
      * global_page_state(NR_ACTIVE_FILE)
      * global_page_state(NR_INACTIVE_FILE)
      
      minus
      
      * global_page_state(NR_FILE_MAPPED)
      
      Namely, if this number is subtracted from the number of saveable
      pages in the system, we get a good estimate of the minimum reasonable
      size of a hibernation image.

      PM/Hibernate: Do not release preallocated memory unnecessarily (rev. 2) · 64a473cb
      Rafael J. Wysocki authored
      Since the hibernation code is now going to use allocations of memory
      to make enough room for the image, it can also use the page frames
      allocated at this stage as image page frames.  The low-level
      hibernation code needs to be rearranged for this purpose, but it
      allows us to avoid freeing a great number of pages and allocating
      these same pages once again later, so it generally is worth doing.
